Description

STATIONARY ACCOMMODATION WITH WALL ELEMENTS MADE OF SYNTHETIC MATERIAL D &A: Description: The invention relates to a stationary housing for containing electrical devices, in particular cable distribution devices. Such housings are frequently used to weather-proof components of the telecommunications and data technology, being arranged on a base, from which the cables exit, a frame that serves to support the above-mentioned components, towards which then they are carried or from which cables are taken. Open-air housings are known, in which the base is connected to a lower base part and both parts are formed together in one piece, the lower base part frequently being embedded in the floor. This lower part of the base serves on the one hand for the mechanical stabilization of the housing in the open air, and on the other hand also for the protection of the cables that come out of the ground. To meet the constantly growing information needs, it is necessary to install new telecommunications and data networks or increase existing networks. Regardless of what types of wiring technologies or radio techniques are used in telecommunication, it is common to all the techniques that electrical components must be moved increasingly from the intermediation centers or from the technical telecommunications buildings in a decentralized manner to colonies or places of communication. referral arranged outside the populations. The applicant has already proposed in other applications itself to double the existing frames on such sockets, by arranging in parallel of similar usual open-air housings, or to form new accommodation structures from hollow profile rails. In this case, they are metal parts that have in themselves a sufficient rigidity of their own and serve in arbitrary ordering for the restructuring of the housings, or the rails themselves are part of the frames for holding the electrical components. Another problem is that the cable distribution devices or similar distribution housings or housings for radio stations, to be established in an increasing manner, must not disturb the harmonic image in existing colonies. The usual outdoor accommodations, uniformly gray, rarely meet this requirement. Another problem is that the metallic outdoor housings or those made of plastic parts according to the state of the art are not comfortable for the service. Therefore, the invention is based on the problem of forming stationary housings of the type described above in such a way that they are comfortable for service, both in terms of the handling of the electrical components and also to enable a quick and easy assembly by means of as possible a person. Another problem is posed by the adaptation of the relatively large stationary housing to the structure of the housing environment. The problem is solved according to the invention through the features of claims 1 and 16. Improvements of the invention are included in the dependent claims. The invention is based on the idea that the pieces of synthetic material are resistant to weathering and can be manufactured with a structural design and arbitrary color components. In addition to this, the pieces of synthetic material are relatively light and can be handled even for large-area pieces of 1m x 1m and a wall thickness of approximately 3mm easily by one person. Starting from this, it is proposed to compose stationary housings of this type from separately prefabricated wall elements made of recyclable synthetic material, which are held together by shape continuity and together enclose a frame stable in shape. This frame serves for the placement of electrical components, for example for the distribution of cables or for containing relay stations or the like. Ideally, the housing consists of front wall parts and rear wall parts of the same type, which are presented at the same time as integral parts of the side walls and / or roof pieces of such a housing, which is formed as a rule in the form of a parallelepiped. Two pieces of this type can surround a metal frame, which is arranged for example on the base of a cable distribution device, by compressing the parts against each other and the mutual fitting of the side pieces of the front and rear halves of the housing according to the principle of groove and tongue. This method or mode of assembly on the surface has been proven in the best way in travel cases and provides the accommodation with a rigidity greater than that of accommodations that are assembled in the corner areas. If necessary, the assembly grooves or assembly areas can also be shaped in the manner of a labyrinth, so that the penetration of water from precipitation is impossible. Insofar as a corresponding wind load or other mechanical loads have to be feared, the assembly areas can be further formed with snap-in devices or snap-in arrangements, so that the halves of the housing can be held together securely. . It is possible to use, instead of two identical components that are easily dislodged, also different parts, in particular when it is necessary to have very large stationary housings. It is then offered in one of the wall elements, for example the front, the possibility of equipment with a lockable opening and to close this same opening in turn with a closure plate consisting of a piece of synthetic material, being able to find application, in the manner of the usual doors, hinges and pivoting lever closures. It is also possible here to apply locks or similar closing devices, which are known per se. For a centering on the frame, the front part and the rear part can also be provided with snap-in lugs or guide arrangements, which are guided and fastened to frame elements formed in a complementary manner. Such guide pieces or supporting parts for the frame can naturally be arranged on the inside on the parts of the housing or wall elements, so that in no case is it possible to dismantle the housing from the outside and only when the closure plate be open Such housings can be provided with a housing roof formed in one piece, which is insertable in turn into the halves of the housing or wall elements and can be fixed with the help of screws or rivets from the inner side of the elements. of wall. The roof of the housing is structured according to the invention in such a way that the assembly areas of the wall elements or respectively the front and rear halves of the housing are covered by corresponding projections on the roof. A housing of synthetic material, optionally sealed, of a cable distribution device of this type, in particular when the floor and cable entries are sealed tightly with corresponding cable seals, for example cable sleeves made of rubber, it develops a lot of heat, which could lead, according to the meteorological situation, to a corresponding formation of condensed water in the roof of the housing. For this reason, it is envisaged to integrate an insert into the ceiling or to form a dripper on the ceiling, so that in any case the condensed water can drip outside the area of the frame or the electronic components arranged on the frame. Alternatively, the formation of condensed water can be avoided by means of a corresponding shaping of the roof, for example, generating a chimney effect through an opening directed outwards. Another possibility is to collect the condensed water once formed in a half-shell or in a sponge-like insert and to guide the water from there to the outside or again yield the water of successive condensation as humidity of the air. For a further stabilization of the wall element, it can be foreseen according to the invention to profile the latter on the one hand. This may consist of a general macrobombing of the components or also in a formation of grooves or arrangement of fins in small parts, preferably on the outer sides of the housing. A stabilization structure of this type can be covered by a corresponding design of the housings, for which a corresponding coloration can also be of help.

The floor plate of the housing is preferably divided, so that the floor halves can be joined to the frame from both sides, or corresponding cable connection sleeves are surrounded on the floor of the housing respectively. As the synthetic material, a polyester material reinforced with glass fiber is preferably used, which is formed as a laminated material or is manufactured as a homogeneous pressed piece (smc-sheet molding compound, sheet molding composition), optionally from a material recycling. However, depending on the size of the part, it can also be an injection molding, which is made of polypropylene or modified polyethylene, which however increases the weights of the parts, when the inherent rigidity is not sufficient. It must be taken into account here that corresponding UV stabilizers are incorporated in the injection molding composition, as is known per se, however, from the prior art. For reasons of heat insulation for the minimization of transpiration water or of sound insulation to avoid disturbing noises, the wall elements can also be covered with an insulation, which is preferably fixed with clamping elements to the wall elements, so that the disassembled housing can easily be taken to a recycling process. A separation by materials of different synthetic materials from each other can be avoided in this way. The same applies to sealing gaskets in doors or gaskets in joints to be provided, if necessary. In order to be able to shape the synthetic material housing as lightly as possible, it is also envisaged to employ either stationary rigid frames made of sheet metal frames or similar elements and to place traction unloading rails in these, in which they can be suspended with corresponding clips or suspension devices cables to be introduced. The load is then produced only on the frame and not on the parts of the housing, so that they can be formed in a correspondingly light manner. However, in smaller housings it can also be provided that the frame is formed as an integral part of a wall element or that the wall elements are reinforced, for example at their corners, in such a way that racks are fastened there or rails can be placed there. traction discharge. An outdoor housing as a cable distribution device can be structured on a plinth, as it often exists, in such a way that a frame stable in shape and made of metal is fixed on the plinth and that from a factory only send the parts of the housing, separated, consisting of floor plate, rear wall, front wall, door placed, a roof and if necessary sealing gaskets, and then complete the outdoor accommodation in a site assembly. With the help of a drawing, the invention will be explained in more detail: FIG. 1 shows, in an exploded view, a complete housing according to the invention with a separate frame; 2 shows a housing according to the invention without a closing element with an integrated frame; Figures 3a to 3e in four views and in a perspective view from above a closed housing according to Figure 1; 4 shows a traction discharge rail for integrating it into a wall element or a frame; 5 shows a traction discharge rail in a side elevation view.

In the following description, identical or identical parts have the same reference numbers. Figure 1 shows a sheet metal frame 1 with walls 11 and traction discharge rails 15 and 12 formed as crosspieces, in which cables (not shown) can be suspended with strain relief with cable rings 13 or support elements 14. These frames have on the side laterally fastening appendages or respectively guide devices 17 or 16, which can fit into complementary guide devices 37, 36 of a front piece 3 of the housing or respectively center it. The front piece 3 of the housing, made of synthetic material, with integrated side wall 33 has an overlapping assembly area 34, which can be brought into engagement with an assembly area, the assembly slot 24 in the side wall 23, structured in a complementary manner, in the rear part 2 of the housing also made of synthetic material. Both pieces of synthetic material 2, 3 are joined together, as shown in the position of use in the exploded pattern, with mirroring symmetry on the frame 1, they are adjusted together until the assembly areas 24 and 34 fit one into the other. other. At the same time, the clamping appendages or guide devices 36, 37 and 25 or respectively 28 fit into parts of the frame 1 correspondingly shaped in a complementary manner.

In the crosspiece 31 of the front piece 3 of the housing and in the crosspiece 21 of the rear part 2 of the housing, assembly areas 38 and 27, 29 can be seen, which serve for fitting the roof 5, which can be placed on both parts 2, 3. The cross members at the same time form integral parts of the roof of the housing, so that the roof 5 also has its assembly area in the corner areas with the other wall elements 2, 3, but on the surface superior of the accommodation. After fixing the roof 5, the shoulder 51 of the roof 5 covers the lateral assembly areas 24, 34 coupled so that water can not enter from above in these assembly areas. An arrangement for discharging condensed water 9, coupled to the roof 5, completes the housing from above, while from the front side can be placed in the opening 32 of the front piece 3 a closure plate 4. This closure plate 4 can be clamped by hinges 43 in the part 3 of the housing, while a handle 42 in combination with a locking arrangement 44 retains this plate in the front piece 3. The front wall is strongly profiled by corresponding grooves 41, so that the closure plate 4 it obtains additional stiffness and at the same time the large surface of approximately 1 mx 1 m is optically subdivided by the corresponding shading. As the frame is generally placed on a lower part, from which the cables reach the housing, the lower side of the housing must be closed on both sides with corresponding floor pieces 6, fins 61 being placed adjacent to the parts 2, 3 of the housing, producing a seal. As a rule, the floor plates are also assembled first, after the cable guides 7 with corresponding sealing sleeves 8, made of rubber, for cables have previously been placed around the cables. Figure 2 shows that the housing constituted by the front and rear parts 30 and 20, which have an equal shape, can be equipped additively or alternatively also with traction unloading rails 12, 15 in one of the two parts of the housing , here in the rear half 20 of the housing with closed rear wall. In this example, the front wall 30 is open, to perform mounting tasks on the rear wall from there, but it could be closed just like the rear wall. A traction discharge rail 15 such, with the structure shown in FIGS. 4, 5 or the like, is disposed on the rear wall 20 and engaged in the reinforced corner areas 22. By means of reinforcements 26 and stable pieces of frame 205, this simple housing is made resistant for use and is even easier to assemble than that described in figure 1. Figure 3a shows the housing completed from the rear side with the roof 5 placed, while figure 3b shows an elevation view side of the housing with the assembly areas 24, 34 that are on the side wall of the housing. Figure 3c is a front elevational view of the closure plate 4 and the roof 5 placed in the housing, while figure 3d shows a top plan view on the roof 5 with the covering appendages 51 described above. In figure 3e a perspective view of a closed housing according to the partial views 3a to 3d is again represented. The housing has been manufactured from polyester reinforced with fiberglass, the individual housing pieces having been preformed in a corresponding press in the factory and having obtained a determinable coloration by the one in charge of them. Figure 4 shows in front elevation view a traction discharge rail with corresponding discharge brackets 152 for suspending cables by means of plastic ligatures. The traction discharge rail 15 can be placed by snap-on lugs 151 in the frame (Figures 1, 2). According to the invention, however, it is also possible to place these fitting tabs on reinforced corners 22 of a front part, a rear part 2 or a housing half 20.

Fig. 5 shows a side elevation view relative to Fig. 4. The pull-out rail 15, with the holding bracket 154 shown here - in contrast to the use-position also usable upside-down, can also cooperate with corresponding cable collars 153; the corresponding captive screw is not shown. Discharge brackets 152 can be used additionally.
