Slipover distribution cabinet

Description of the invention

The present invention relates to a method for expanding the installation space of an open-air switch cabinet and an assembly kit for a new switch cabinet unit.

Known is a switch cabinet, which is usually installed outdoors and contains technical, e.g. electrical or optical distribution devices for e.g. telecommunication systems, e.g. telephone installations, with associated power supply devices and devices for disconnecting and connecting cables for a specific spatial area. Such switch cabinets must - in addition to sufficient structural stability and resistance to vandalism etc. - now meet further requirements, for example, not too strong electromagnetic radiation should be released into the environment, and for use primarily in warmer countries, the temperatures inside the switch cabinet should not rise too high despite the fact that there are electrical components that emit heat, but nor should they fall too low.

Switch cabinets of this kind are essentially made of either metal or plastic, the plastic combining the advantage of being able to be manufactured cheaply with the advantage of a non-electrically conductive material, even if an electrical component touches the switch cabinet housing unintentionally. construction, there is no risk of electric shock when touching the casing from the outside.

As regards the possibility of sufficiently cooling such switch cabinets, cooling by circulating air is known. For this purpose, the body walls are double-walled, and ambient air can circulate in the space between the walls, i.e. enter from below and exit from above, as a result of which, on the one hand, the interior is heated by sunlight and, on the other, heat dissipation on the internal walls which are heated by electric units in the main chamber.

In addition, modern switch cabinets with electromagnetic compatibility tightness have been created, so that electromagnetic radiation can only take place within a predetermined limit value.

Such switch cabinets are partly on private property, but often also on public property, so that the relevant municipality has to grant permission for the erection of such switch cabinets. As long as the telecommunications companies were also in the hands of the state, this did not create any problems, but as privatization increased, public authorities refuse or charge fees for staking, completely disregarding the fact that the consent procedure must be conducted and cost a lot of time. .

This problem occurs with all newly built switch cabinets, especially in new-build areas, or when space is created in an existing switch cabinet for technical components, especially electrical components, and a further switch cabinet would have to be installed next to it in order to enlarge it.

A further technical problem arises when replacing an existing switch cabinet for technical reasons, i.e. when, for example, the body of an existing switch cabinet has to be replaced in order to improve the EMC-tightness or the cooling capability.

It should be noted that, as a rule, the switch box is embedded in a deeply buried plinth, most often made of concrete, and recently also made of plastic, into which the earth cables leading to the switch box and leaving from it are inserted from below. back, and to which the usually existing mounting frame is also fastened with bolts, on which the elements of the technical development, in particular electrics, and the surrounding body are fixed. The body is - especially with the aforementioned double-shell structure of the inner body - either made of permanently joined plates or of a frame of the body which is closed by a plate covering. The outer body is attached to such an inner body with a plate covering at a distance from the outside.

From the German patent application DE 101 05 993 A1, a construction kit is known for creating an electrical equipment cabinet, which includes an outer body, an inner assembly frame, a covering for an inner assembly frame, several plinth boxes of different dimensions, and support plates for connecting the assembly frame to a plinth box and several mounting positions for the support plates on the mounting frame with which a cabinet for

PL 204 649 B1 of electrical appliances above the old pedestal of an old cabinet for electrical appliances. In order to be able to fix the cabinet for electrical equipment on the plinth boxes that protrude at different heights above the ground, especially the plinth boxes that end flush with the ground, the support plates, which create the connection between the mounting frame and the plinth box, can be placed in different mounting positions for the frame assembly.

From the German patent application DE 199 41 413 A1, a movable distribution system for supplying power to poles is known, comprising a housing and supply and output connections arranged therein in several supply modules, the housing being formed with bearing supports between which they are detachably arranged with different sides of the supply modules, the supply modules being thus enclosed in the tubs, that the distribution lines provided between the inlet and outlet connections are surrounded by the tub and between the supporting supports only the tub surfaces face each other, while the open sides of the tubs only face the outer side of the housing in order to make the outlet ports accessible there. In addition, the housing has a door that covers the open sides of the bathtubs from the front, and a cover projecting beyond the supporting supports, on which lugs for the crane are provided.

Furthermore, from French patent application FR 2 752 103 A1, a device for measuring and distributing electrical energy is known, in particular on construction sites, with a supply part and a distribution part, the supply part having a retaining element for holding the measuring device and the switch part comprising an energy distribution and protection device and, moreover, the retainer is designed to fix the junction box containing the measuring device, and the supply part is electrically connected to the distribution part via a connecting element, the connecting element having a clamping device to which the junction box can be connected.

The object of the invention is to provide a method for replacing, in particular enlarging, the body of a switch cabinet and a construction kit therefor, the replacement of which is problem-free and in which the switch cabinet remains in its original position and where no new installation permit or building permit is required and a possible construction permit is possible. there is uninterrupted work.

The method of expanding the installation space of an open-air switch cabinet having a body, an embedded plinth and a mounting frame, according to the invention, is characterized in that the body of the old switch cabinet is removed, a new empty plinth is slipped in top view over the old mounting frame and the old plinth, and settles and levels out on the ground base, the internal, slip-on free space of the new plinth is greater than the external width of the old plinth, and the new body slides from above onto the old mounting frame, is placed on the new pedestal, aligns and secured, the new body having a larger interior space than the old body.

PL 204 649 B1

Preferably, the kit comprises electromagnetic compatibility sealing strips, in particular in the form of a self-adhesive metal foil, especially aluminum foil, especially in the form of a bitumen strip covered with a metal foil.

By sliding the new plinth, as well as the new body - after removing the old body - over the old internal components of the switch cabinet, i.e. leaving the old plinth in its position and the technical transmission elements installed on it, including technical, especially electrical functional elements, interrupting the network, i.e. disconnecting technical, in particular electrical, functional elements inside the switch cabinet.

Since the connection cabinet remains in its previous position and only the outer dimensions of the new body increase more or less greatly, no new permission from the authorities is usually required for installation.

By removing the soil around the plinth, but preferably not all the way to the lower edge of the old plinth, the old plinth not only remains in its position, but most often is not completely deprived of its stability during conversion work, so that tipping is not to be expected during these steps. work without an external cover, an old junction box.

However, if necessary, deliberately at any time - by removing the soil up to the lower edge of the plinth - the dismantled connection box can be rendered unstable, so that it can be straightened again, for example when installed at an angle, or to be moved slightly away from its installation location. The latter is, for example, often necessary when the old junction box is positioned with its back side too close to an existing building, garden wall or the like, and has to be pushed away from there a few centimeters in order to slide the new switch box over it.

By inserting a new, empty top view, the plinth box, preferably in the form of a closed box profile, and in particular thanks to the plinth, preferably on the sides outside the plinth feet, protruding from the plinth, its installation surface is so enlarged that, despite the smaller installation depth, a secure support is guaranteed in the ground.

The plinth can in this case preferably be assembled before being put on from a plinth box that is usually one-part, but possibly also multi-part, and the plinth feet, the plinth feet preferably in turn consisting of lateral plinth feet and one on one side, and thus, for the two side sections, a continuous one. plinth foot plates.

For transport, the pedestal feet are often already attached to the plinth, but turned 180 [deg.] With respect to the vertical axis, so that the plinth foot plate does not protrude beyond the plinth box. In this transport position, the pedestal can also be used when building a new switch cabinet.

This reduces, on the one hand, the transport volume of the plinth and, on the other hand, the parts can be produced from each preferred material, for example the base plates of the plinth made of galvanized sheet steel grating or plastic grating, while the side parts of the base base may be bent steel sheet parts. The plinth box itself is made, for example, of concrete, plastic, metal or a mixture of these materials.

Manufacturing the base plates in the form of lattice parts, in particular of plastic, has proved to be advantageous for a number of reasons: on the one hand, thanks to the lattice shape, it is possible to perform a simple vibrational compaction and, in this case, align the plinth exactly horizontally. If the base plate of the plinth is made of plastic, it is easy to make recesses and cut-outs in the plate at the installation site, for example to accommodate cables coming out of the switch cabinet.

After aligning the plinth, mainly horizontally, but also roughly at a lateral distance from the old plinth, the new body is placed on the new plinth, in such a way that the new body is lifted by means of lifting eyes screwed into the body by a crane, in particular by the loading and unloading crane of the truck that delivers it, and slid from the top onto the electrical components of the old switch cabinet, freed from its old housing, as well as on its plinth, since the new plinth generally extends less far upwards than the old plinth, the new plinth also embraces part of the old plinth at its height. As a rule, for further work it will be necessary to remove the outer covering of the new body, i.e. the outer side wall, the rear wall and the door, which, depending on the size and weight of the new body, may take place before or after sliding on it.

PL 204 649 B1

In contrast, removal of the roof module, most often consisting of the top cover and the intermediate part below it, which is seated on the intrinsically stable main part of the main body, is absolutely necessary, since it is necessary to slide it on to this main part of the new body for insertion. Lifting lugs screwed in or otherwise attached, for crane attachment.

For this purpose, when a new body is delivered, the roof module is only fitted loosely and is no longer permanently connected to the rest of the body.

After the new body has been connected, in particular by bolts, to the new plinth, in particular the lower edge of the new body to the upper edge of the new plinth, the new body - and therefore also the new plinth already associated with it - is fed, preferably by means of a horizontally arranged adjusting screw in the new plinth. to the required distance from the old plinth in the horizontal direction.

To this end, the body, and in particular the frame of the new body, has crossbars that extend horizontally slightly below the height of the upper edge of the body, into which or through which adjustment screws can be screwed from outside by means of horizontal threaded holes, which rest on the outer surface of the old plinth.

Preferably also the old mounting frame on which the transmission elements are built is detached from the old plinth, in particular by unscrewing or breaking the connecting bolts, and is instead fixed, in particular screwed, against the new body.

This is done, for example, with the known metal or plastic punched strips which are screwed on the one hand to the old mounting frame and on the other hand to the new body on the inside, in particular to its frame. For this purpose, in such a frame, in particular, the sliding blocks in the undercut grooves that extend along the edge profile can be screwed with screws.

Such locking preferably takes place in the upper part of the old mounting frame as well as, if appropriate, in its lower part. Thanks to the use of punched tapes, various forms and positions of fixing the old mounting frame to the new body are possible.

In addition, an EMC tightness is achieved in that, in the top view, the circumferential gap between the old plinth and the new body is closed by an EMC seal overlapping the upper side of the old plinth.

If the new body only surrounds the old body with a small gap, this is done by sticking a strip of metal foil, for example an aluminum foil bituminous strip, with one edge lying on the upper side of the old base and the other edge on the crossbar of the new body frame running at this height. .

If the new body serves to enlarge the interior space for new technical or electrical components, then this larger open area next to the old base is closed with a suitable plate made of metal or covered with metal.

In this additional interior space, there is already a new mounting frame - preferably already connected to the new body, in particular its frame - for accommodating the new electrical components.

Finally, the hitherto unguarded new body is again covered with a covering for better access, so that the side walls are attached from above to the outside, and so is the rear wall, and the hinged door is suspended by inserting a hinge rod that extends the entire height of the door. guided through both the hinge lugs of the side part and the hinge lugs of the door.

In this connection, in particular, care must be taken that the circumferential, combined splash and electromagnetic compatibility seal in the door and / or the enclosure frame, which is preferably made of a conventional soft plastic or rubber, preferably with a hollow section, as a seal, is not damaged. splash-proof, on the outer surface of which is placed metallized or containing a metal fabric, preferably a self-adhesive foil as an EMC seal.

Finally, a roof module is attached which, with its lower edge, encircles the upper edge of the side walls and the rear wall to form a positive fit. In this case, the roof module reaches downward with its securing projections having a transverse opening between the casing frame and the outer side wall. When the door is fully open, the roof module is secured against lifting by inserting a safety bar at a time horizontally from the front to the

The intermediate space between the casing frame and the side wall of the casing extends to form a positive fit both through the openings in the securing projections of the roof module and through the corresponding openings in the corresponding securing protrusions extending from the casing frame outwardly. After the door has been closed and locked, this safety bar is no longer accessible from the outside and therefore cannot be removed and therefore the roof module cannot be removed and consequently also the side walls and the rear wall cannot be lifted upwards from the suspension, and - if the lock is not damaged - the door cannot be opened either.

The subject of the invention is shown in the embodiment in the drawing, in which fig. 1 shows the insertion of a new plinth, fig. 2 - a new plinth inserted, inserted, fig. 3 - a new inner body slipped on, fig. 4 - the inner body slipped on, assembled and secured , Fig. 5 - the inner body covered with a perimeter cover, Fig. 6 - with an additional roof module, Fig. 7 - the inner body itself, Fig. 8 - the body covered with plates, Fig. 9 - body with additional covers at the front and rear in the lower part, Fig. 10 - body with additionally placed rear wall and front door, Fig. 11 - body with a roof module for additional mounting, Fig. 12 - body ready assembled, Fig. 13 shows the plinth itself.

Before explaining the procedure for inserting a new switch cabinet on the basis of FIGS. 1 to 6, its individual parts will be described separately with reference to FIGS. 7 to 13, namely the new plinth 2 and the new body 3, and different states of construction of the new body 3 based on FIGS. 7 to 12.

Fig. 13 shows the new plinth 2 which has been assembled from a plurality of separate parts by means of bolted connections.

On the one hand, the hollow, and therefore seen from above, the plinth box 2a, which is usually made of plastic, concrete, a mixture of the two materials or some other non-corrosive material. Below it, in the transverse direction 20 of the greater transverse dimension of the pedestal box 2a, on the outside of the lateral regions, the pedestal feet 2b are fixed, with which the pedestal box 2a is placed on the ground, in which for this purpose the pedestal box 2a is excavated to the desired height.

The pedestal feet 2b consist of plates 2d with preferably an inherently stable grating, in particular a galvanized steel sheet grating with perpendicular ribs or a plastic grating. They have a width that preferably corresponds exactly to the horizontal depth, i.e. the width, of the plinth box 2a and project laterally beyond the plinth box 2a. The plates 2d extend under the plinth box 2a only in correspondence with the thickness of the side walls of the plinth box 2a, so that in the plan view the free space in the plinth box is not reduced.

In this position, each plate 2d is fixed by means of two approximately triangular side parts 2c, which with one of their two perpendicular outer edges are bolted to the plate 2d, in particular to its upper side, and are the upper, tapering part connected to the box 2a. plinth and thus position the plates 2d under the plinth box 2a and at a distance therefrom.

The plates 2d are used to enlarge the installation surface in relation to the base surface in a plan view of only a narrow circumferentially extending part - one piece or a vertically or horizontally divided multi-piece plinth box and can theoretically project outwards, instead of cross-section on the narrow sides, also on the front sides and back sides, or on all four sides. As a result, however, an optimally large footprint with a relatively small excavation required around the old plinth is achieved by mounting plates which extend in cross section beyond the sides of the plinth box 2a.

Figures 7 to 12 show the construction phases of an increasingly completed new body 3. The inner body has a cubic shape and is intrinsically stable thanks to the body frame 16, which is assembled from edge profiles 17, which at their ends, especially in the corners of the body frame 16, are connected to each other, in particular bolted, by means of appropriate corner connectors.

In addition to the edge profiles 17 along the edge of the cubic inner body 21, there are cross-members 34 extending circumferentially horizontally between the vertical bars in the lower third part of the frame 16 of the body, against which the adjusting screws 13 are also arranged horizontally from the outside towards the inside.

PL 204 649 B1

The adjusting screws 13 are disposed in pairs at a distance from one another on the front and rear crossbars 34 in the transverse direction, preferably also one in the middle of the short crossbars 20 in the transverse direction.

The frame 16 of the body is closed on the sides, on the rear side and on the upper side by preferably electromagnetic-compatible sealed plates, which preferably lie in the area of ​​the thickness of the edge profiles 17, so that only the front side is open, in particular only in this case. the area located above the cross-member 34 and the base surface between the bottom-circumferential edge profiles 17.

Shown are two screw-in lifting lugs 12 lying on the upper plate cover, which, if necessary, namely to lift this inner body 21 vertically, can be screwed into upwardly open internal threads 22 of two diagonally oriented in relation to it. body frame upper corner links 16.

In contrast, Fig. 8 shows a state in which the inner body 21 thus described is already provided with side walls 8 which are brought from outside to the side surfaces of the inner body 21 and connected to it by means of a positive fit or attached in some other way.

Fig. 9 shows a state in which, unlike the equipment of Fig. 8 front flap 23 and tail flap 24 - which, like the side walls 8 and the rest of the cover, are preferably made of plastic, cover the front and rear lower areas of the inner body 21, so that they are also preferably fitted with a positive fit onto it from the outside or otherwise attached and thus enclose this area from the circumferential crossbars in the lower third part to the lower end of the body frame 16 at the front and rear, while the side walls 8 preferably extend the full height of the frame body 21.

10 shows a state in which the inner body 21 is additionally equipped with a rear wall 11 and a door 4a, 4b on the front side. The door 4a, 4b is in this case suspended on the longitudinal edges of the front side by corresponding hinges constituting the pivot axis, while the rear wall 11 in turn is attached from the outside by suspension from above or otherwise.

As primarily shown in the top views in Figs. 10d and 9d, the rear wall 11 and the side walls 8 are positioned offset outwardly with respect to the inner body 21 - with top and bottom openings, so that there may be between them air flowing upwards due to the chimney effect.

For the same reason, the doors 4a, 4b are also designed as double-walled with through openings from the bottom upwards, preferably the inner wall of the door 4a, 4b is again made tight in an electromagnetic-compatible manner.

Fig. 11 shows the state of the body 3 when assembling the roof module 50, which consists of an upper intermediate part 7 and a cover 5, and preferably projecting projections 25 downwardly for insertion into the rest of the body 3, in particular between its inner body. 21 and its outer cover and for screwing with the inner body 21, in particular its frame 16.

As the roof module 50 in top view extends beyond the inner body 21 and also covers the rear wall 11, the side walls 8 and the doors 4a, 4b when closed, the fixed roof module 50 - as shown in the final state - prevents these parts from being lifted upwards. and thereby removing them from the inner body 21.

Fig. 1 shows the slipping of the plinth 2 shown in Fig. 13 onto an old mounting frame 6 equipped with technical or electrical functional elements and onto an old plinth 2 'that supports it, to which it is connected by means of fastening screws 18.

For the sake of clarity, the old assembly frame 6 does not show the technical or electrical functional elements usually fixed there with screws and wired there, but for the sake of clarity, only the cable inlets 27 for the cables are shown in the base plate 26 of the assembly frame 6. The electrical functional elements, which are not shown, do not extend beyond the base surface of the old pedestal 2 'when viewed from above, since they were surrounded by it prior to the removal of the old body, not shown here, which was mounted on the outer periphery of the old pedestal 2'.

2 shows its final position on the ground after the new plinth 2 has been slipped on. As it is primarily shown in Fig. 2b, the new plinth is significantly lower than the old plinth 2 '. Because in the old 2 'plinth, the ground level, and therefore the usual level

The ground is visible, so around the old pedestal 2 ', especially in the transverse direction on the sides of the old pedestal 2', the soil is removed so deep that a new pedestal can be set up in the excavated area at the positioning level thus formed. 2 with its erecting plates 2d, which level is selected such that the upper edge of the new pedestal is at the level of the previous ground level 40.

Depending on the immersion depth of the old pedestal 2 ', this new orientation level as shown in Fig. 2 may be slightly below the level of the old pedestal 2' or also on it, preferably the new orientation level 29 is chosen to be above it. old plumbing so that the old plinth 2 'does not have to be completely excavated, which reduces the stability of the old plinth 2' and thus the old switch cabinet during remodeling work.

It is possible to vary the height of the new base 2 by means of different heights of the base side parts 2c.

The view according to Fig. 2d further shows that the width of the new plinth in the plan view, and thus transversely to its extension in the transverse direction 20, is only so large that the inner, suitable for the free space of the new plinth 2, in particular its box 2a, is slightly larger than the outer width of the old plinth 2 '.

In the transverse direction, the new plinth may also hardly fit over the old plinth, or - as shown in Fig. 2 - be considerably larger in order to create space next to the old mounting frame 6 later for a new mounting frame. For this reason, the new plinth 2 is then slid over the old plinth so that it is on one of its sides close to the lateral (right or left) inner circumference of the new plinth 2, in particular its box 2a, and the additional interior space is thus available only after one side of the old mounting frame 6, i.e. in one piece.

After the new plinth 2 has been inserted in this way and has been brought horizontally at the correct height, the new body 3, in particular only its inner body 21, as shown in Fig. 3, is slipped as shown in Fig. 3 from above - preferably suspended from a hook. crane - onto the old mounting frame 6 so that it is completely surrounded by the new internal body 21. The new body 3, in particular its inner body 21, is lowered until it stands on the upper side of the new plinth 2 and is finally connected to it by means of fastening screws 18.

Preferably, the inner body 21 does not project laterally - in top view - beyond the outer periphery of the plinth box 2a, as can be seen from FIG. 4 after fixing the inner body to the new plinth 2 by means of fastening bolts 18.

Fig. 5 shows, analogously to Fig. 10, the new body 3, i.e. with the outer covering on the inner body 21 in the form of side walls 8, rear wall 11 and two doors 4a, b fixed outside. a front view according to fig. 5b and a top view according to fig. 5d, the outer circumference of the new body 3 equipped in this way is larger than the outer circumference of the new plinth box 2a, so that the side walls 8 extend through the entire height of the inner body and the plinth box 2a, and the front hatch 23 'and rear hatch 24' used cover in terms of not only the lower region of the inner body 21, and thus downwards from the crossbars 34, but also the lower part of the new box 2a of the plinth located below it.

FIG. 5a also shows a new mounting frame 6a which is attached sideways to the old mounting frame 6 in the inner body 21 of the new body 3, which, according to FIG. 4a, can already take place before the new inner body or the new body 3 is slipped on or also right after that.

Also - differently from Fig. 1 to Fig. 6 - the inner body 21 can be slipped on already covered by the side walls, the rear wall and the front flap and the rear flap, that is, in the condition shown in Fig. 5.

In Fig. 5, especially in Fig. 5c, moreover, the fixing of the old mounting frame 6 is shown, above all in the upper region - with the new body 3, which is preferably done by screwing a section of the punch tape 14, which is preferably made of metal or plastic, the central region of which is secured with bolts to, for example, the upper end of the old mounting frame 6 and whose front and rear ends inclined upwards are bolted to the front and rear, transversely extending edge profiles 17 of the body frame 16, preferably by bolting to the sliding keys 15, which are slidably positioned along these edge profiles 17 in respective undercut grooves.

FIG. 6 shows the final state, that is - with the lifting eyes 12 removed again - after the roof module 50 has been placed on the upper side of the rest of the new body 3 and connected to it.
