Appliance for making the oblong concrete construction segments

(54) Equipment for production of elongated concrete building components

The present invention relates to an apparatus for producing elongated concrete structural components which enables the production of components in at least two different widths.

For the efficient production of concrete structural components intended, for example, as walls, ceiling elements or roof elements of building structures, a single-dose process has been used so far. In this process, by depositing and curing the concrete mixture, a long concrete slab is formed, which is then cut into a series of panels of shorter lengths. Because a relatively long cure time (approximately 14 hours) is required, this single-dose process is more efficient. rather than making individual shorter boards, because a large number of such boards would have to be produced at the same time. The length of the board before cutting into short pieces may be about 150 meters at a weight of 230,000 kilograms. The shorter cut lengths can range from approximately 2.4 meters for wall panels to 15.2 meters for roof panels.

It is desirable to be able to use the same device to make such plates in different widths, since when the overall lengths of the finished plates vary, their total weight must be kept within the capacity of the hoisting crane. For example, with shorter lengths, parts can be manufactured. 2.4 meters wide while 1.2 meters wide is used for larger lengths. The previous approach to this problem was that all slabs were made in uniform widths, which were then cut in the longitudinal direction, and different placement fields of the concrete mix were used for different widths. Although this achieves the same end result, it is. The lack of this known procedure duplicates the equipment, increased wear of the saw blades with diamond teeth, and the need for costly additional working times.

SUMMARY OF THE INVENTION The present invention relates to an apparatus for producing elongated concrete components of various widths, comprising an elongated horizontal storage field with a longitudinally oriented bottom and side walls, the storage field according to the invention being divided longitudinally along its bottom into longitudinal sections movable · Transverse direction to each other, further comprising a longitudinally displaceable molding partition, retractable between the sections of the deposition field parallel to the side walls and forming a partition in the deposition field upon their insertion so that it is possible to produce either a structural concrete component of one integral width extending from one side wall to the other if the molding partition is B 3 and the sections of the stacking field are pushed together, or separate concrete members in each section when a molding partition is inserted between these sections.

According to one embodiment of the invention, a plurality of transverse rails are arranged below the depot field, spaced perpendicular to the longitudinal dimension of the depot field. To support the stowage section sections during their relative transverse movements, a series of wheels traveling on these rails are rotatably mounted at the bottom of the stowage section sections.

According to a further embodiment of the invention, the device for inducing transverse movement of the storage field sections is provided with an elongate actuating member extending over¹ substantially the entire length of the storage field, and stored with the possibility of longitudinal movement. A series of swinging arms extend from the actuator to the sides and symmetrically to both sections. The rocker arms are pivotally connected to said actuator and to the corresponding section of the storage field at points spaced apart from one another. The longitudinal movement of the actuator is provided by a hydraulic cylinder. As a result of this arrangement, this longitudinal displacement of the actuator ensures the resulting transverse movement of the sections of the storage field. .....

A series of vertical pivot arms pivotally connected between the molding partition and the row of anchors serve to lift and lower the molding partition, so that the longitudinal movement of the molding partition causes its resulting vertical movement.

According to another embodiment of the invention, only one of the sections of the storage field is movable, while the other is fixed. However, the sections remain relatively movable relative to each other. .

The device thus designed is easily adaptable to production in at least two different widths of the parts to be manufactured. It does not require duplication of equipment such as prior art, nor longitudinal cutting of parts. It combines the benefits of lower acquisition costs with increased productivity and equipment efficiency.

The device according to the invention is suitable for both fixed-field or movable-field concrete mix solutions. It makes it possible to produce slabs of a continuous width extending from one side wall of the storage field to the other, which are then cut into individual parts and lifted by crane, or two relatively narrow slabs if the lengths of the parts to be cut cut if they were to stay in full width.

1 and 2 show a molding device with a fixed storage field of the conventional type. The apparatus has an elongated horizontal concrete placement field 22 with a longitudinal bottom 24 and longitudinal side walls 26 and 28. Along the placement field 22 is a track with rails 30 and 32 for carrying different working units not shown in Figure 1; 2, for example, for a concrete mix storage device and a cutting device that move along the length of the storage field 22.

In accordance with the invention, the storage field 22 is divided in the transverse direction into sections movable in the transverse direction relative to each other. In the embodiment shown, these sections are two, namely sections 34 and 36, wherein the bottom 24 is divided by a gap 38 at its center so that it consists of two separate bottom sections 40 and 42. The division of the storage field 22 is provided by a removable molding. a partition 44 which can be inserted between the two sections 34 and 36 parallel to the side walls 26 and 28.

In the arrangement shown in Figures 1 and 2, where the molding partition 44 is inserted between sections 34 and 36, two separate concrete members 46 and 48 can be produced in the sections -34 and 36 of the deposition field 22. 44 in the manner described in more detail below, the sections 34 and 36 of the deposition field 22 are moved to one another so that the bottom sections 40-and 42 will form a continuous bottom and it will be possible to form a concrete member extending from one side wall 26 to the second side wall 28.

To ensure the relative transverse movement of the storage bed sections 34 and 36, a plurality of transverse rails 50 are disposed below the storage field 22 perpendicular to the longitudinal dimension of the field 22. The transverse rails 50 may be spaced apart, e.g. Field 22. The length of the storage field 22 is about 150 meters. A row of spline wheels 52 is rotatably attached to the bottom of the storage field 22 to allow the cross rails 50 to travel. As a result, the sections 34 and 36 can be moved in the transverse direction by means of these grooved wheels 52. In this case, each wheel 52 is supported by a suitable bearing in a housing 54 fixed to the bottom of a section 34 or 36 of the storage field. As can be seen from the drawings, the axes of the spline wheels 52 are parallel to the longitudinal dimension of the storage field 22.

Since the device 20 according to FIGS. 1 and 2 operates with a fixed receiving field 22, the longitudinal rails 30 and 32 as well as the cross rails 50 are fixedly attached to the floor by means of a concrete base 55.

Due to the relatively large spacing between the transverse rails 50 of six meters and the extra weight of the concrete members produced, it is clear that - to avoid undesirable sags - between the support points formed by the transverse rails 50 and wheels 52 with their bushings 54 ' other supporting structures. For this purpose, the Z-shaped beams 56 extend along the sides of the sections 34 and 36 of the storage field 22 below the edges of the bottom sections 40 and 42. When, in the present embodiment, the Z-shaped beams 56 extend continuously over the entire length of the storage field 22, they may be formed of individual parts of approximately 12 meters in length, suitably joined together. A plurality of I-shaped beams 58 are disposed transversely between the beams 56. at intervals of approximately 0.75 m in the direction of the length of the deposition field 22. Finally, the C-shaped beams 60 running through the support sections bottom 40, 42 serve. transversely with respect to the I-shaped beams 58

Giant. 3 and 4 provide details of the right side wall -28, the left side wall 26 being a mirror image of the right-hand wall so that the same reference numerals are used for it. The movable side walls of the molds are well known and the illustrated embodiment serves only to provide one suitable example. The exact details of the side walls -26 and 28 are therefore not essential to the invention.

The right side wall 28 has an actuator 64 in the form of a generally triangular plate with a pivot center 66 mounted on a Z-shaped beam 56, so that it is positioned on a suitable bracket 68 extending from the wall of the beam 56 below the right side wall 28. The right side wall 28 is secured to the upper portion of the actuator 64 by suitable means such as by screwing.

In order to be actuated upwardly by the actuator 64a and the right side wall 28 of FIGS. 1, 2 and 3, a cam lifter 76 extends from the side of the storage box 22 along its length. a variable distance from the edge of the storage field 22, as best seen in FIG.

1. In this case, it is movably mounted with respect to the deposition field 22 in that it is pulled and sprayed by means of hydraulic actuating cylinders (not shown) located at its ends.

To lower the side wall 28 to the position shown in FIG. 4, the cam lifter 76 is pulled to a position in which one of the lowered areas of the front surface wall 78 engages the sliding cam member 70, thereby allowing actuator 64 and the right side wall 28. fall off. In most cases, the side wall 28 and actuator 64 do not fall off spontaneously, but after the previous impact.

3 and 4, side wall extensions 80 and 82 are also shown, which can be added to the right side wall 28 if thicker plates are to be produced, if desired. The extensions 80 and 82 are also shown in dash-dotted lines in FIG. 2. It goes without saying that, in the manufacture of a pair of narrower and thicker plates with similar extensions or extensions, the molding partition 44 also has to be provided.

FIG. 5 shows details of FIG

A mechanism according to the invention for raising and lowering the molding partition 44 and for transversely moving the sections 34 and 36 of the first embodiment of the apparatus 20 of FIGS. 1 and 2. The molding partition 44 is mounted for vertical movement. a series of vertical swinging arms 84, one of which is shown in FIG. The upper end of the vertical swing arm 84 is pivotally connected in the pin 86 to the molding partition 44 and the lower end is pivotally connected to the anchor member 30 by the pin 88. In an embodiment of the device 20 that operates with the fixed storage field 22, the anchor members 90 are fixedly attached to the floor.

The molding partition 44 is further provided with a longitudinal displacement device which comprises a hydraulic cylinder 92 disposed at both ends thereof. This hydraulic cylinder 32 is pivotally attached to pin 44 at pin 94 and pin 96 to a suitable fixed support, not shown in the drawings.

Obviously, the longitudinal displacement of the molding partition 44 by raising and retracting the hydraulic cylinder 92, results in the resulting vertical movement of the molding partition 44 as the vertical swinging arms 84 rotate about the pins 88. As shown in FIG. 5, the molding partition is raised almost to its upper This position is shown in FIG. 2. With the fully lowered position as seen in FIG. 5 when the molding partition 44 is moved below the bottom 24 of the concrete mixture laying field 22.

As further seen in FIG. 5, the transverse displacement means of the sections 34 and 36 of the first embodiment of the apparatus 20 comprise a longitudinal actuator 98 in the form of a long steel tube. The actuator 98 extends over substantially the entire length of the storage field 22 and is supported with the possibility of longitudinal but not transverse displacement. In order to move the actuator 98 in the longitudinal direction, a hydraulic cylinder 100 is attached to one end thereof. The actuator 98 preferably extends through the center of the storage field 22, just above the transverse rails 50. To avoid a collision between the actuator 98 and the anchoring member 90 of the vertical swinging arms 84, the anchoring members 90 are provided with passages 102 through which the actuator 98 can pass freely. If necessary, the passages 102 can be bearings or bushings that secure the actuator 98 against lateral movements .

In order to translate the longitudinal movement of the actuator 98 to the resulting transverse relative movement of the storage field sections 34 and 36, the swing arms 104 are inserted between the actuator 98 and the sections 34 and 36. Each rocker arm 104 is pivotally connected to the actuator 98 at one end 106 and 108 to a corresponding section 34, 36 of the storage field 22. In the illustrated embodiments, the ends 108 of the swingarms 104 are connected directly to the sleeves 54 of the spline wheels 52.

In the illustrated arrangement with the actuator extending substantially through the center of the storage field 22 and with the swinging arms 104 extending from the actuator 98 sideways and symmetrically thereto, it is apparent that the lateral forces acting on the actuator 98 are substantially in equilibrium such that minimal. It can be seen from FIG. 5 that the longitudinal displacement of the actuator 98 caused by the operation of the hydraulic cylinder 100 causes the resulting transverse displacement of the sections 34 and 36 of the deposition field 22.

Giant. 6 and 7 show the bottom region 24 at the point of contact of the bottom sections 40 and 42. FIG. 6 shows the molding partition 44 interposed between the two bottom sections 40 and 42, while in FIG. 7 the molding partition 44 is lowered. As FIGS. 6 and 7 are enlarged, they also show the welds 110 connecting the bottom sections 42 and 44 to the Z-shaped beams 56.

In Fig. 6 it is seen that the molding partition 44 is inserted between the edges 112 and 114 of the bottom sections 40 and 42. Thus, in the sections 34 and 36 of the deposition field 22 it is possible to produce separate concrete panels 34 and 36.

In Fig. 7, the molding partition 44 is removed from the position between the sections 34 and 36 of the storage field 22 and is lowered below the bottom sections 40 and 42. In this figure, the sections 34 and 36 are displaced closely together so that the contact edges 112 and 114 of the bottom sections 40 and 42 are together and form a seal against leakage of uncured concrete. With this arrangement, a solid concrete panel 116 extending from one side wall 28 to the other side wall 26 can be produced.

6 and 7, the bottom sections 40 and 42 are curved upwardly near their edges 112 and 114. When a pair of plates 46 and 48 according to FIG. 6 is produced, this curvature ensures the formation of curved bottom edges of the panels 46 and 48 in the region 118. When a single panel 116 is produced, as is the case in FIG. 7, these curves form a channel 120 that has a visual function and serves to reduce the difference between the joint and the center of the wider plate. This is advantageous in those cases where the overall width of the building structure is equal to the sum of the widths of an odd number of narrower concrete components having relatively small lengths. In such a situation, the full width of the panels satisfies the capacity of the lifting means, but at least one half-width panel is required to assemble the overall dimension of the building structure.

The work of the first embodiment of the device 20 according to the invention, which has been described with reference to Figures 1 to 7, will now be summarized. It is assumed that relatively narrow components are produced. After the batch of concrete mixture has been deposited, the hardened panels 46 and 48 are in the position shown in FIGS. 1, 2 and 6. The cam lifters 76 on the sides of the deposition field 22 are then displaced in the longitudinal direction to allow release of the controls 64 and left and right side walls. 26 and 28. The loose side walls 26 and 28 are allowed to fall off by pivoting around the pins 66 and assuming the position shown in FIG. 4. As mentioned above, an impact, such as a kick, may be needed to release the side walls 26 and 28.

At this point, a hydraulic cylinder 100 is actuated at the end of the actuator 98 to separate the bed sections 34 and 36 by the swinging arms 104. The molding partition 44 is then lowered below the bottom sections 40 and 42 by actuating the hydraulic cylinder 92 let it stretch. In this situation, the panels 46 and 48 rest loosely on top of the bottom sections 40 and 42 and can be cut transversely to the required lengths. Lowering the molding partition 44 and tilting the side walls 26 and 28 creates the necessary access spaces for the saw blade to be used for cutting.

After cutting, the individual parts are lifted by crane from the deposition field 22 and transported to a storage area or a transport vehicle. Prior to the commencement of the next batch of concrete mixture, the side walls 26 and 28 are raised by the action of the cam lifts, and the molding partition 44 is also raised by the hydraulic cylinder 92. This is properly positioned between the sections 34 and 36 of the deposition field 22, and these sections 34 and 36 are moved together to press against the molding partition 44 and seal the bottom of the mold as shown in FIGS. 2 and 6. In this state, Sections 34 and 36 are cleaned and lubricated with molding oil to prepare the next batch of concrete mix.

Obviously, in order to produce full width plates, the mechanisms for lifting the molding partition 44 and for separating the sections 34 and 36 shown in FIG. 5 are not used. field.

Figure 8 shows an alternative embodiment of the device 122 of the invention. The device 122 is a variation of the device 20 described above and a number of elements that are unchanged retain the original reference numerals. The device 122 of FIG. 8 is also a fixed storage field operating device and thus has longitudinal rails 30 and 32 for moving the individual working devices along the storage field 22.

The basic difference between the device of Figures 8 and the device of Figures 1 to 7 lies in the means for transversely moving the sections 34 and 36 of the storage field 22 relative to each other. The device 122 of FIG. 8 also has transverse rails 50 and grooved wheels 52 carrying sections 34 and 36 of the storage field 22 and ensuring their transverse movement. However, instead of the longitudinal actuator 98 and the swing arms 104, transversely directed hydraulic cylinders 124 are used. One end of each of the hydraulic cylinders 124 is connected to sections 34 and 36, preferably to the bushes 54 of wheels 52 at the attachment points 126. the hydraulic cylinders 124 are. attached at points 128 to keyed carriers 130 which, in the case of a fixed storage device 122, are fixed to the floor. Other wedge-shaped members

132 they serve as stops limiting the transverse movement of the sections 34 and 36 by abutting the sleeves 54 of the wheels 52.

Figures 9 and 10 show the shape of the vertical rocker arms used to raise and lower the molding partition 44 in the apparatus of Fig. 8, with the molding partition 44 remaining unchanged. 9 and 10, neither the anchor member 90 nor the passage 102 is visible since they are not needed. The lower ends of the modified swing arms 132 are pivotally connected in pins 134 to the support members 136 which abut the rails 50. Since the force exerted on the pins 134 always acts in one direction, the use of the support members 136 provides an advantageous and efficient way of anchoring the lower ends of the rocker arms 132. The upper ends of the modified rocker arms 132 are connected as before to the partition 44. 19, it can also be seen that the arranged vertical swing arm 132 is provided with a threaded transfer tube 138 screwed onto the threads 140 which allows the vertical swing arms 132 to be lengthwise adjusted.

It should be noted that Fig. 9 provides a representation of two positions of the molding partition 44 relative to the bottom 24 of the deposition field 22. The solid line shows the lowered position of the molding partition 44 in which the molding partition 44 is fully removed from the depositing bed 22. on the other hand, the upper end position used to pull the molding partition 44 out of the gap between the panels 46 and 48 is shown. 9 but is a slightly lowered position relative to the upper limit position shown by the dashed line when the line 142 merges with the bottom 24.

FIG. 11 shows a further embodiment of the device according to the invention, namely a movable storage field device 144. The entire support field 146 travels in the longitudinal direction on the grooved wheels 148 on the track formed by the rails 150 and 152. The transverse rails 154, instead of resting on the floor like the corresponding rails 50, are supported by the wheels 158. the working devices usually remain stationary, while the storage field 146 is displaced in the longitudinal direction. The I-beams 156 are mounted on the sides of the device, on top of which the rails 158 are mounted. The variable field rotary hydraulic motors 163 are equipped with rubberized drive wheels 162, which engage the sides of the beams 156 and friction all over. move the storage fields 146. The rails 156 with rails 158 also allow support of the working devices of the device under which the storage field 146 is moved.

The movable storage field 146 of the device 144 of FIG. 11 is otherwise substantially the same as the fixed storage field 22 of the device 122 of FIG.

8. However, the transverse rails 154 are no longer fixed to the floor, but are connected to the wheel housings 148. The lower ends of the vertical swing arms 132 are attached to suitable projections (not shown) on the rails 154. Furthermore, the hydraulic cylinder 92 shown in FIG. 44 is attached to a fixed support, but is attached to the frame of the movable storage field 146.

Figures 12, 13, 14 and 15 show a fourth embodiment of the device according to the invention, shown mainly schematically. The storage field 200 is divided transversely into two longitudinal sections 202 and 204. Although the sections 202 and 204 are movable relative to each other as in the previous embodiments, the storage field 200 differs from the above-described embodiments in that only one of the sections 202 and 204 is movable relative to the floor, while the other is rigidly connected to the floor. In the illustrated examples, the left-hand section 202 is movable and the right-hand section 204 is fixed. This particular arrangement is structurally simpler in many ways than the embodiments described above, since it minimizes the need for heavy moving elements.

It can be seen from FIG. 12 that two separate concrete panels 206 and 208 are shown in the deposition field 200, shown in dashed lines. The concrete panels 206 and 208 are disposed on days 210 and 212 divided into respective sections 202 and 204, and these bottoms 210, 212 are separated from each other by a molding partition 214 and lined on the opposite sides by side walls 216 and 218.

The procedure of the individual operations required to produce the half-width panels 202 and 204, for example, will now be described

12 meters, referring to Figs. 12, 13 and 14. Ref. 12 illustrates a situation where both the left and right side walls 216, 218 and the molding partition 214 are in the position for depositing and curing the concrete mixture. As shown in FIG. 13, after hardening of the concrete panels 206 and 208 in the same manner as described above, the movable section 202 of the storage field 200 moves in a transverse direction from the fixed section 204. The arrangement is such that the initially movable section 202 is displaced from both the molding baffle 214 and the fixed section 204, while the molding baffle 214 remains in the position in which it is adhered to the concrete member 208. At some point of transverse displacement of the movable section 202 an element of the molding partition 214, which it begins to pull in the transverse direction from the fixed section 204 and thus from the concrete member 208. This particular process is described in more detail with reference to FIG. 21.

As shown in FIG. 14, the molding baffle 214 is lowered below the bottom 210 and 212 and the left and right side walls 216, 218 are folded out. In this state, the concrete members 206 and 208 may be cut into portions of any desired length, as was. explained above, and thereafter they are lifted from the corresponding deposition fields 202, 204 by crane.

Giant. 15 illustrates an arrangement in the manufacture of a single full-width concrete member 220, for example 2.4 meters. In this arrangement, the molding partition 214 remains beneath days 210 and 212, and the movable section 202 of the storage field 200 is close to the fixed section 204 thereby forming an integral storage field for the production of a full width panel.

Upon completion of the laying and curing process resulting in panel 220, the two side walls 216, 218 are folded out and the concrete panel 220 is cut into individual slabs of the required length which are lifted from the laying field 200 as described above.

Fig. 16, which can be compared to Fig. 12, shows various construction details of the apparatus with a storage field 200, while Fig. 17 shows further details of the molding partition 214. The molding partition 214 consists of left and right lower sections 222 and 224, left and right. the middle sections 226 and 228 and the left and right upper sections 230 and 232 connected by the support member 234. The lower sections 222 and 224 are permanent portions of the molding partition 214, while the sections 226, 228, 230 and 232 are fitted as needed when it is desired to form plates of greater thickness than is possible by the sections 222 and 224 themselves.

In FIG. 16, a dashed line depicts the position of the molding partition 214 'lowered beneath the bottom 210 and 212, either to free up space for cutting concrete panels 206 and 208, as in FIG. 14, or to form a single concrete panel. full width, ie 2.4 meters. In the lowered position shown in dashed line in FIG. 16, the upper sections 230 and 232 as well as the support member 234 are removed, and the middle sections 226 and 228 are rotated around the corresponding pins 236 and 238 after removal of the screws 240 and 242, as shown in FIG. 17.

As best seen in FIG. 17, the molding baffle 214 in the up position is retained by the small interference pads 244 and 246 beyond the stops 248 and 250 of the movable and rigid bottom 210, 212, thus supporting the molding baffle 214. Lateral fixation of the molding baffle 214 is provided by abutting the sides of the stops 248 and 250 to the vertical flanges 252 and 254 of the L-shaped members extending from the corresponding overlap flats 244 and 246 and attached to the molding baffle 214 by screws 256 and 258.

As shown in FIG. 16, the left and right side walls 216 and 218 are substantially identical to the corresponding left and right side walls 26 and 28 described above with reference to FIGS. 3 and 4. As in the previous embodiments, each side is The wall 216 and 218 are provided with a triangular actuator 264 rotatable about a pin 266 which is suitably secured to the respective bottom 210 or 212. A sliding cam member 270 is connected to the rear end 274 of each actuator 264 by screw adjusters 272.

To allow the actuators 264 and side walls 216 and 218 to be pushed upwardly to the position shown in FIG. 16, cam lifts 276 are best positioned along the storage field 200, which are best seen in FIG. 22 and are described below. The cam lifter 276 has an outer surface at a variable distance from the side of the deposition field. As the lifter 276 is moved in the longitudinal direction, the left and right side walls 216 and 218 are raised as described above.

As also mentioned above, extensions 280 and 282 can be fitted to the side walls 216 and 218 when thicker plates are produced, as is apparent from FIG. 16, these extensions 280 correspond to the intermediate sections 226 and 228 of the molding baffles. 214, and the mold extensions 282 to the upper extensions 230 and 232.

As mentioned above, the distinguishing feature of the embodiment of Figures 12 is that one of the sections of the storage field is fixed to the floor. As shown in FIG. 16, in the illustrated example of a particular embodiment, section 204 is secured to the floor 284 by built-in anchors 286, and the corresponding bottom 212 is supported by I-beams 288 and support structure 230.

The movable section 202 of the storage field 200, on the other hand, is movable in the transverse direction, i.e. laterally, with the transverse movement caused by the hydraulic cylinder 292. The hydraulic cylinder 292 is provided with a protruding piston rod 294 whose end 296 is attached to the slide assembly 298. The sliding assembly 298 includes a bottom 210 of the movable section 202, a support structure 300 formed by closed cross-section beams 302, a draw bar 304 positioned between the beams 302, and sliding plates 306. The slide assembly 298, and more particularly the slide plates 306, are slidably mounted on the outer surface of the hollow beam 308 extending along the body of the hydraulic cylinder 292. The beam 308 is fixed in position by carriers 310 attached to the embedded anchors 312. it is anchored to the retaining structure 316 at the end of the beam 308, thereby ensuring that the cylinder body 292 does not move.

Preferably, to facilitate mounting tolerance requirements, the connection between the cylinder end 314 and the retaining structure 316, as well as the connection between the end 296 of the piston rod 294 and the slide assembly 298, is designed to allow rotational movement about a vertical axis. It is further preferred to use mechanical stops (not shown) to prevent further pulling of the piston rod 294 into the cylinder body 292 beyond the position that causes the fully open arrangement of Figs. 13 and 14.

Giant. 18 is a section similar to FIG. 16, but showing the piston rod 294 of the hydraulic cylinder 292 fully extended. and the two bottoms 210 and 212 of the sections 202 and 204 are knocked together at their stops 248 and 250 to form a single deposition field of 2.4 meters wide. In this arrangement, the molding partition 214, as indicated by the dashed lines in Fig. 16, is in its lowered position. In the lowered position of the molding partition 214, the upper sections 230 and 232 are visible in FIG. 17, as well as the support member 234. The middle sections 236 and 238 are manually rotated inward to accommodate the available space.

In the arrangement shown in FIG. 18, for cutting and removing the concrete member 216, it is only necessary to fold up the side walls 216 and 218 in the manner described above and indicated in bold lines in FIG.

Next, with reference to FIGS. 19, 20 and 21, the manner in which vertical and transverse displacement of the molding partition 214 is performed will be described.

Similar to the embodiments described above, the vertical displacement of the molding baffle 214 is accomplished by a hydraulically actuated swing arm assembly including the swinging arms 318 and 320 and the hydraulic actuator cylinder 322. The molding baffle 214 extends approximately 180 meters in length and may consist of individual sections any suitable length.

The rocker arm assemblies and the hydraulic cylinder actuator, i.e. the rocker arms 318 and 320 and the hydraulic actuator cylinder 322 are positioned at appropriate intervals along the length of the molding partition 214. The rocker arms are pivotally connected at pins 324 and 326 to feet 328 and 330, respectively. The hydraulic cylinders like cylinder 322 are also rotatably mounted on a pin 334 by which they are attached to one of the feet, for example to the foot 330.

Not all swing arms need to be directly fitted with hydraulic actuators. As can be seen in FIG. 19, the rocker arm 318 is directly operated by the hydraulic cylinder 322, while the second rocker arm 320 is only passively rotated. By way of example, only one of the fifteen swing arm assemblies is directly hydraulically operated. More specifically, 120 swivel arm assemblies are spaced 1.5 meters apart from each other over a length of 180 meters. Most swingarms are passive as an exemplary arm 320, and only every fifteenth swing arm is directly actuated, such as an exemplary swing arm 318. Thus, in the present case, the device has eight directly actuated swing arms as an arm 318 at 22.5 meters apart. .

To raise and lower the molding partition 214, the swinging arms 318 and 320 are rotatably mounted at their upper ends 336 and 338 to the molding partition 214. Between the lower sections 222 and 224 of the molding partition 214, as shown in FIG. Support members 334 fastened to corresponding end brackets 342 and 344. The retaining clips 346 and 348 of the studs 350, 352 provided with slotted holes are joined to the horizontal C-shaped support members 340.

The purpose of the slot-shaped apertures in the liner tabs 346 and 348 is to allow thermal expansion along the length of the molding partition 214. Preferably, the pin retainer assembly has circular holes in the longitudinal direction of the molding partition 214 to form a reference fixed point. from which the molding baffle 214 extends and contracts on both sides in the longitudinal direction.

The transverse movement of the molding baffle 214 is caused by the transverse adjusting arms 354 shown in FIGS. 20 and 21. As can be seen from the figure, these adjusting arms 354 are attached to each of the above swing arm assemblies. As best shown in FIG. 20, the pivoting joints in the pivots 324 and 326 of the swingarms 318, 320, as well as the pivoting joints in the pivots 334 of the hydraulic cylinders 322 allow transverse movement of all the swingarm assemblies and hence the molding partition 214.

A particular feature of the deposition field 200 of FIG. 12, and further, is that the movement of the movable section · 202 in the transverse direction from the fixed section 204 while compressing the hydraulic cylinders 292 (see FIGS. 16 and 18) The adjusting arms 354 and the connection assembly 356 carried by the movable section 202.

The connection assembly 356 shown in FIG. 21 includes a downwardly extending bar member 358 and a strut 360 mounted to the support structure 300 of the movable section 202. In FIG. 21 the arrangement in which the piston rod 294 of the hydraulic cylinder 292 is fully extended and the stops 248 and 250 of the bottom 210 and 212 are abutting each other is marked with solid lines, while the arrangement in which the piston rod 294 is retracted and the storage bed section 202 is is shown in dotted lines with the same reference numerals.

The lower part of the bar element 358 is provided with an opening 362 through which the transverse adjusting arm 354 passes. Near the end of the transverse adjusting arm 354, a support element 364 is movably mounted so that it can be engaged by the bar element 358 as the movable section 202 moves laterally from section 204 and compressing the hydraulic cylinder 292.

The operation of the attachment assembly 356 will now be described, beginning with the configuration shown in solid lines in FIG. 21, where the stops 248 and 250 of the bottom 210 and 212 abut, the piston rod 294 shown in FIG. 18 is fully extended, and the molding baffle 214 is in the lowered position shown in FIG. 18. By way of non-limiting example, the width of the molding baffle 214 between abutment points 248 and 250 may be 40 · cm (arrangement) according to Fig. 12). . When the movable section 202 is fully retracted from the fixed section 204, there is a 5 inch gap on each side of the molding baffle 214 (see arrangement of FIGS. 13 and 14). The total transverse movement of the movable section 202 from the single width storage array arrangement of FIG. 15 to the fully retracted position of the movable section 202 is thus 50 cm.

Since the piston rod 294 initially retracts, the only movement is the transverse movement of the movable section 202 away from the fixed section 204. During this initial movement, the transverse adjusting arms 354 connected to the swing arm assemblies 318 and 320 do not move and the apertures 362 at the end the downwardly extending rod elements 358 slide freely along the transverse adjusting arms 354. After the movable storage section 202 has shifted by 45 centimeters of its fifty centimeter trajectory, the downwardly extending bar member 358 abuts against the support member 364, thereby initiating a lateral movement of the transverse adjuster arms 354.

This lateral movement of the transverse adjusting arms 354, which results in an equal displacement of the rocker arms 318 and 320 'and the molding partition 214 laterally, is five centimeters. At this point, the arrangement of FIG. 14 is achieved in which the molding baffle 214 can be raised by the action of the hydraulic cylinders 322 (FIG. 19).

After the molding baffle 214 has been raised, the cylinders 292 are actuated again to pull the piston rods 294 by 10 cm, resulting in the arrangement of FIGS. 12 and 18.

In order to move from the arrangement of FIGS. 12 and 18 to the arrangement of FIG. 13, the hydraulic cylinder 292 is allowed to retract the piston rod 294 so that it can perform its final ten centimeter displacement. During the first five centimeters of this displacement, the molding baffle 214 normally remains at the fixed storage field section 264, although it is possible that the high adhesion of the produced concrete member 208 'to the bottom 2d (Q of the movable section 202 initially causes the However, assuming that the molding baffle 214 remains at the fixed section 204, the linkage assembly 356 will allow the transverse adjustment arms 354 to remain stationary. During the last five centimeters of the lateral movement of the movable section 202, the elements of the attachment 356, in particular the rods 358 and the support elements 364, engage one another so that they pull the transverse adjusting arms 354 and move the molding partition 214 laterally.

If the molding baffle 214 remains initially adhered to the movable section 202 and is thereby pulled away from the fixed section 204 of the storage field 200, after five centimeters the displacement limit of the sliding pin assemblies 324, 326 and 334 is reached, thereby stopping the displacement molding baffles 214 to the side. The movable section 202 of the storage field 200 then continues in the final five centimeters of sideways movement.

Fig. 22 shows the left side wall

216 together with the retracted cam lifter 276. For longitudinal movement of the cam lifter

276 serves a hydraulic cylinder 370 which, due to the displacement of the cam lifter 276, causes a rotational movement of the triangular actuator 264 (FIGS. 16 and 18) and thus the side walls 216 as the cam members 270 come into contact with the more extended surface portions 372 of the cam actuator 276. has been described above.
