Translation of description of equivalent WO 2004076278 A2

Überstülpbarer distribution cabinet

I. FIELD

The invention relates to a distribution cabinet which is placed usually outdoors and technical, such as electrical or optical distribution systems for eg low power systems, such as telephone systems, with associated power supplies and Kabelab -.. / - Connection devices for particular geographical areas receives.

II. Background

Such cabinets have - besides a sufficient structural stability and a resistance to vandalism etc. - today meet other demands, for example, may not be issued to strong electromagnetic radiation to the environment, and for use primarily in warmer countries, the temperatures may inside the distribution cabinet not get too high despite the accommodated there, heat-emitting electrical subassemblies, but also not fall too low.

Such cabinets are generally made of either metal or plastic, said plastic have the advantage of cheaper manufacturability with the advantage of an electrically non-conductive material, so that even if unscheduled contacts the casing of the distribution cabinet never the danger by an electrical component, that when touching the case should the person receives a shock from the outside. With regard to the sufficient cooling ability of such distribution boxes, it is already known, to effect cooling by air circulation. To this end, the carcass walls are double-walled, wherein the space between the walls circulate the ambient air, thus enter the bottom and emerge above, on the one hand to heat the inside by the sunlight and secondly a heat dissipation on the inner wall, which by the electrical components are heated in the main room, causes.

Moreover, modern cabinets are designed EMVproof; so that electromagnetic radiation can take place only within the limits set out.

Such cabinets are partly on private property, but often also on the public domain, so that the respective municipality must grant approval for setting up of such a distribution cabinet. As long as the telecommunications companies were state-owned, this hardly caused problems, with increasing privatization rejects the public sector the establishment from or calls for a fee for the preparation, apart from the fact that an approval process be run must and is quite time consuming.

This problem arises in all newly prepared distribution cabinets, so especially in new residential areas, or if in an existing distribution cabinet space for technical, in particular electrical installations is exhausted, and to extend a further distribution cabinet should be placed next to it.

Another, technical, problem in replacement of an existing distribution cabinet for technical reasons, so if z. B. must be replaced because of the improvement of EMC sealing or of the body of an existing distribution cabinet cooling ability. It should be noted that a distribution cabinet usually on a deep in the ground buried base, usually made of concrete, in recent times, made of plastic, is seated, in which the Power Panel hinführenden and again leading off this underground cables are inserted from below, and in which both of the normally existing mounting frame to which the technical, in particular electrical components are mounted, as well as the surrounding is screwed corpus. The body is - especially in the aforementioned clamshell design with respect to the inner body - either permanently connected plates created, or of a body frame which is closed by planking. On such inner body of the outer body is by means of planking spaced externally fitted.

III. Summary of the Invention

a) Technical Object

It is therefore the object of the present invention, a method for

Replacing, in particular increasing, to provide the body a distribution cabinet and a kit available for this purpose, whose exchange is not a problem and in which the distribution cabinet at the original location remains and thus no new Aufstellgenehmigung or building permit is necessary.

b) solution of the problem

This object is solved by the features of claims 1 and fourteenth Advantageous embodiments result from the dependent claims.

By slipping over a new base and a new body - after removing the old structure - about the old interior of the cabinet, so when leaving the old base in its position and it constructed transmission technology, so the technical, in particular electrical functional parts, is not a power failure, thus switching off the technical, in particular electrical functional elements needed inside a control.

Since the cabinet remains in its previous position and increase more or less only the external dimensions of the new body, no new Aufstellgenehmigung's regulatory agency usually necessary.

By removing the soil around the base, but preferably not completely down to the bottom edge of the old base, not only the old base remains in its position, but is usually not completely stripped during construction work to its stability, so that an overturning of bared old cabinet during work is not to be feared.

However, if necessary at any time intentionally - by removing the soil to the bottom edge of the old base - the undressed old cabinet destabilize him - again to make straight or even to get ready slightly from its location here - for example skewing. The latter is, for example, often necessary when the old cabinet with its back too close to an existing building, garden wall or the like positioned was, and a few centimeters must be slid from there to putting the new cabinet above.

By slipping over the new, hollow in plan view, the base box, preferably in the form of a closed box profile and in particular of the base box to preferably laterally outwardly projecting mounting bases its footprint is enlarged so that - ensures a reliable support in the ground - despite the lower mounting depth ,

The base is preferably before slipping over most unitary from, but possibly also assembled multipart base box and the base feet, the pedestal feet preferably again consists of plinth side panels and one on each side and thus for two side portions continuous plinth panel.

the base feet are often already attached to the base box for the transport, but rotated by 180 ° relative to a vertical axis so that the Sockelfuß- plate does not protrude outward beyond the base box. In this transport position, the base can also be used in case of reconstruction of a distribution cabinet.

This reduces to a transport volume of the base and, secondly, the parts can be produced from the most favorable material, such as the plinth panels of galvanized sheet steel gratings or plastic grids, while the plinth side plates can be steel-bending parts. The base box itself consists of z. B. concrete, plastic, metal or a mixture of these materials.

The preparation of the base foot plates as grid members and, in particular made from plastic has proved to be advantageous for several reasons: first, a shaking in and thus leveling of the base is possible precisely in the horizontal plane in a simple manner by the lattice structure. If this base foot plate made of plastic, can be prepared in a simple manner on site breakthroughs and cutouts in the plate to accommodate, for example, it leads away from the distribution cable.

After alignment of the base, especially in the horizontal, but also roughly in the lateral distance to the old base that the new body placement carried out on the new socket by the new body means screwed into the body lifting lugs by a crane, in particular the Ladekran of delivery trucks, raised and on - freed of its old housing - is put electrical components of the old cabinet and also on its base from above, as the new base is generally less far upward protrudes than the old base, so that the new body in the altitude also overlaps a portion of the old base. In general, for the Further work to remove the outer skin of the new body, so the outer side walls, rear wall and doors can be necessary, which can be done before or after slipping over, depending on the size and weight of the new body.

In contrast, the removal of the roof module, usually consisting of a top lid and an underlying upper intermediate part, the rest on the inherently stable main part of the new body, usually mandatory, as in this main part of the new body from above the for slipping over lifting eyes are screwed for the attachment of the crane or otherwise secured.

To this end, the roof module is placed loosely in the delivery of the new body and not already connected to the rest of the body.

After joining, in particular screwing, of the new body with the new socket, in particular the lower edge of the new body with the upper edge of the new base is preferably by means of a horizontally lying adjusting member screws in the new body of new structure - and thus also the already connected to it new base - placed in the horizontal direction to the desired distance from the old base.

To this end, the body and especially of the new body horizontally extending transverse struts body frame just below the level of the upper body edge comprises at which or through which the adjusting member screws can be screwed by means of horizontal threaded holes from the outside and on the outer surface of is old base support.

Preferably, also the old installation frame to which the transmission equipment is attached, detached from the old base, in particular by twisting or tearing off of the connecting screws, and, instead, with respect to the new body is fixed, in particular screwed. This happens for example by the known perforated strips of metal or plastic, which are screwed on one side to the old installation frame, and the other end on the new body on the inside, in particular on its body frame. For this purpose, especially on such a body frame sliding blocks in undercut grooves which extend along the edge profiles of the body frame, screwed.

Such fixation is preferably carried out in the upper region of the old installation frame and, if necessary, in the lower region. By using the perforated belts of different shapes and positions of the old installation frame on the new body can be fastened.

In addition, EMC sealing is achieved in which the considered in the plan, encircling gap between the old base and the new body by a - acting on the top of the old base - EMC seal is closed.

If the new body surrounding the old base with only a small distance, this is done by sticking a strip of metal foil, such as a coated aluminum foil bitumen strip at one edge on the top of the old base and the other edge on at this level extending transverse struts of the body frame of the new framework rests.

If the new body to increase the interior space for new technical or electrical fixtures used, then larger open area is closed next to the old base by means of an appropriate, made of metal or coated with metal, plate.

In the additional interior space - preferably already connected to the new body and especially its body frame - already a new mounting frame to accommodate the new electrical fixtures available. Recently the previously entmantelte for better accessibility new body will again planked, so attached, the side walls of the upper outer quadrant, as well as the rear wall, and the wing doors hung by inserting the continuous over the entire height of the door hinge rod from above, both by hinge loops of is passed side part as well as by hinge loops of the door.

It is important to take particular care that arranged in the doors and / or in the housing frame, encircling combined Splash and EMC gasket is not damaged, which preferably consists of a conventional soft plastic or rubber material, preferably with a hollow cross section, as a splash -Abdichtung there, and on the outer surface of a metallized or containing a Metailgewebe, preferably self-adhesive, film is applied as EMC seal.

Finally, the roof module is placed, which the upper edge of the side walls and rear wall via positively engages with its lower edge. The roof module protrudes with locking projections, which have a transverse bore between the body frame and the outer side wall to the bottom. The roof module is secured with doors fully open against lifting by a respective securing rod is inserted from the front in the space between the housing frame and side wall of the housing horizontally so that it both the bores of the securing projections of the roof module and the housing frame outwardly analog capture processes appropriate by bores therethrough penetrates form-fitting. After closing and locking the doors this security bar is no longer accessible from the outside, thus can not be removed, so that the roof module is not removed and the side walls and the back wall will be posted not upwards in the sequence, and - if the lock can not destroyed is - and the front doors are not opened. c) Embodiments

An embodiment according to the invention is described below in closer detail. Show it:

FIG. 1, the slipping-over of the new base, Fig. 2 the slipped-over, deposed new socket, Fig. 3, slipped over the inner body, FIG. 4 the slipped-over, settled and fixed inner body, FIG. 5 the disguised circumferentially inner body, Fig. 6 with additional top roof module; Fig. 7 shows the inner body only, Fig. 8 clad with side panels, Fig. 9 in the additional panels, front and rear in the lower region, FIG. 10 with additional attached rear and front doors, FIG. 11 with additional aufzusetzendem roof module, Fig. 12 ready assembled state of the body, and Fig. 13 the base alone.

Before with reference to FIGS. 1 to 6 the procedure is explained while slipping over the new distribution cabinet, its individual parts, namely the new base 2 and the new body 3 will be described individually with reference to Figs. 7 to 13, while the different construction conditions of the new body 3 with reference to FIGS. 7-12.

Fig. Figure 13 shows the new base 2, which is screwed together from several individual parts:

On one hand, the hollow, so in plan considered continuous, base box 2a which is usually made of plastic, concrete, a mixture of both or other non-rusting material. Meanwhile, in the transverse direction 20, the larger transverse dimension of the base box 2a, outer side portions are fixed to mounting bases 2b with which the base box 2a the ground is turned off, which is removed down to the desired height towards this.

The mounting bases 2b consist of plinth plates 2d, preferably of an intrinsically stable grid, in particular a grid of galvanized sheet steel with vertical webs or of a plastic grid. These have a width corresponding preferably exactly horizontal depth, ie width of the base box 2a and are transversely 20 laterally over the base box 2a. The plates 2d rich in plan considered in only according to the thickness of the side walls of the base box 2a among these, so that the viewed in the plan space in the base box is not thereby reduced.

In this position, the plates 2d are secured by means of two approximately triangular side parts 2c, which are bolted to one of its two right-angled outer edges to the plate 2d, especially with the top and with the tapered upper portion of the base box 2a are connected and as the plates move 2d below the base box 2a and at a distance from this.

The plates 2d serve to increase the floor space compared to the base of the supervision only narrow circumferential portions of the - one-piece or vertical or horizontal split, multi-piece base box and can theoretically protrude instead of the transversely outer narrow sides also front and back to the outside, or on all four sides. However, the result of an optimally large standing area with only a relatively small excavation necessary to the old base around arises in securing the plates above in the transverse direction over the sides of the base box 2a.

Figures 7 to 12 show the increasingly completed the new body 3. Construction phases The inner body has a cubic shape and is inherently stable due to a body frame 16, which is composed of edge profiles 17, at their ends, especially in the corners of the body frame 16, on corresponding corner connectors connected, in particular screwed, are.

In addition to the edge profiles 17 run along the edges of the cube-shaped inner body 21 crossbars 34 horizontally circumferentially between the vertical struts in the lower third of Korpusrahm ens 16 against which Alignment screws 13 also arranged horizontally directed from outside to inside.

The adjusting member screws 13 are spaced from each other in pairs disposed on each of extending in the transverse direction of the front and rear cross-member 34, also preferably each in the middle of the transverse to the transverse direction 20 extending short transverse struts.

The body frame 16 is at the sides, at the rear and at the top closed by - preferably EMC-proof plates which are preferably in the thickness range of the edge profile 17 such that only the front side, in particular of only the above the cross-member 34 lying region, is open and the base surface between the bottom peripheral edge profiles 17th

On the upper planking lying two screw-in lifting lugs 12 are shown, which, if required, namely for the lifting of this inner body 21, in upward, upwardly open internal threads 22 of two diagonally opposite upper corner joints of the body frame 16 can be screwed.

The FIG. 8 show other hand, a state in which the inner body 21 as described above is already equipped with side walls 8, which are set by the outside against the side surfaces of the inner body 21 and connected, by lowering form-locking with, or otherwise secured manner. Fig. 9 shows a state in which with respect to the equipment according to Figure 8 is a front cover 23 and a tailgate 24 - cover the inner body 21 the front and rear lower section -. Preferably as the side walls 8 and the rest of the cladding is preferably made of plastic in that they are also preferably positively to this externally mounted or otherwise secured, and thereby close off the area of ​​the circulating in the lower third cross members to the lower end of the body frame 16, front and rear, whereas even the side walls 8 over the entire height of the body frame 21 preferably pass.

The Fig. 10 show a state in which the inner body 21 with a rear wall 11 and front doors 4a, b is additionally provided. The doors 4a, b are mounted on the longitudinal outer edges of the front side in corresponding hinge as the pivot axis while the rear wall 11 in turn is externally by hooking from above or otherwise secured.

As especially the supervisions 10d and 9d show, are rear wall 11, side walls 8 to the inner body 21 offset toward the outside at a distance - open top and bottom - positioned so that between air through the chimney effect may conditionally flow upward.

Also, the doors 4a, b are double-walled for the same reason with through holes from bottom to top, wherein preferably the inner wall of the doors 4a, b, in turn, is EMVproof formed.

The Fig. 11 show that of the body 3 state upon completing by placing the roof module 50, which consists of an upper intermediate part 7 and a lid 5, and preferably downwardly projecting protrusions 25 for insertion in the remaining body 3, in particular between the inner body 21 and its outer lining and fitting with the inner body 21, in particular its body frame 16, serve. As the roof module 50 viewed from the top projects beyond the inner body 21 and rear wall 11, side walls 8 and the doors 4a, b covers in the closed state, prevents the fixed roof module 50 - as in the final state of FIG illustrated. 12 - lifting these parts upwards and thus their removal from the inner body 21st

Figs. 1 show the pushing over of the base 2 shown in Fig. 13 over the old, fitted with technical and electrical functional parts, mounting frame 6 and the carrying it old base 2 ', with which it is connected by means of fastening screws 18.

On old installation frame 6 are for reasons of clarity that there is usually bolted and wired technical or electrical functional elements not shown, but it is only in the base plate 26 of the mounting frame 6, the cable inlets 27 shown for clarity. The electrical functional parts not shown extend in plan does not consider the side but on the base of the old base 2 'addition, since they before removing the old, not shown here corpus, which on the outer periphery of the old base 2' this sat up, of were enclosed.

The Fig. 2 show after slipping over of the new base 2 which deposited on the base end position. Such as especially Figs. 2b shows the new base 2 is considerably less high than the old base 2 '. Since the old base 2 ', the ground level, so that normally existing ground surface level, it can be seen, is at the old base 2' around, especially in the transverse direction laterally of the old base 2 ', the soil removed so deep that in the remote area of new base 2 with its insurgency drives to be 2d situated on the resulting new status level 29, which is selected so that the top of the new base 2 at the level of the previous ground level is 40th Depending on the depth of immersion of the old base 2 ', this new status level as in FIG. 2 just below the state level of the old base 2' are or even higher, preferably the new status level is 29 chosen such that it is above the old standard of living located to the old base 2 'not having to completely free dig what the stability of the old base 2' is reduced and thus the old cabinet during construction work.

There is the possibility to vary the height of the new base 2 2c by different high-side base parts.

The plan view of FIG. 2d further shows that the considered in the plan width of the new base, ie transverse to the transverse extension 20, is so large that the inner, überstülpfähige clearance of the new base 2, ie, in particular its base box 2a, just is slightly larger than the outer width of the old base 2 '.

In the transverse direction 20 of the new base 2 can also fit just above the old base 2 'or -. As shown in Figure 2 shown - be much larger in order to make room for a new mounting frame later next to the old installation frame 6. For this reason, the new base 2 is then placed over the old base 2 ', that this with one of its sides close to the lateral (right or left) the inner circumference of the new base 2, in particular its base box 2a is applied, and the additional interior thus , is only available on one side of the old installation frame 6, ie in one piece.

After is deposited in this manner, the new base 2 and oriented horizontally at the correct height, 3 as shown in FIGS of the new body 3, in particular only the inner body 21, as shown in Fig 3 from above, -.., Preferably to a crane hook hanging - placed over the old installation frame 6, so that it is completely surrounded by the new interior carcase 21st The new body 3, in particular the inner body 21 is lowered with it until it rests on the top of the new base 2, and then screwed with this means of fastening screws 18th Preferably projects - viewed from the top - the inner body 21 is not laterally, as can be seen on the outer periphery of the base box 2a also with reference to Figure 4 after mounting by means of mounting screws 18 between the inner carcass 21 and a new base 2..

Fig. 5 shows the condition 10 of the new body 3 in analogy to the FIG., That is with attached external cladding on the inner body 21 in shape of the side walls 8, the rear wall 11 and the outer hinged two front doors 4a, b. As show above all the front view of Fig. 5b and the plan view of FIG. 5d of the so-equipped new body 3 outer circumference is larger than the outer circumference of the new base box 2a, so that the side walls 8 over the entire height of the inner body 21 and the base box 2a pass, and also the front door used 23 'and the tailgate 24' cover not only the lower portion of the inner body 21, ie downstream of the transverse struts 34, but also the underlying part of the new base box 2a in terms of height.

Fig. 5a also shows the new mounting frame 6a of the old installation frame 6 then the new body 3 is fixed laterally then the inner body 21, which take place according to the Fig. 4a before the slipping-over of the new inner body 21 or of the new body 3 may or may subsequently.

Likewise - be put over already planked with side walls, rear wall and front cover and tailgate of the inner body 21, so by the Figure 5 state shown - notwithstanding Figures 1 to 6...

. Figs. 5, in particular Figure 5c also shows the fixing of the old installation frame 6, especially in the upper portion - with the new body 3, which preferably by means of screwing a piece of perforated tape 14 which is preferably made of metal or plastic, takes place, its central region on z. B. the top of the old installation frame 6 is screwed, and which obliquely upwards front and rear facing ends with the front and rear, extending in the transverse direction 20, edge profiles 17 of the body frame 16 to be screwed, preferably by screwing to sliding blocks 17 which are slidable in corresponding undercut grooves along these edge profiles the 17th

Fig. 6 transmits the final state, thus - after the lifting lugs 12 have been removed - after the placing of the roof module 50 on top of the remaining new body 3 and connecting therewith.
