The invention relates to a support especially for lightning conductors. In order to protect objects from lightning and other harmful effects of atmospheric electricity on roofs with low inclination - flat, hangar, counter and saddle - it uses a lightning conductor system. The lightning conduction system consists of a network of wire-mesh lines made of galvanized steel or copper conductors, or ropes that are generally laid on cast-iron steel supports for the roof covering.

Support of lightning conductors for flat roofs according to ČSN 35 7622 or MS. of the invention No. 160536 consists of a pedestal of a circular or square pedestal which is laid loose and of a web protruding from the center of the pedestal. To the web, the conductor is fastened either by a steel plate, by a screw and by a nut, or by means of a mounting bracket. All parts are made of metal - gray cast iron or steel.

The disadvantage of this embodiment of the lightning conductor support is the difficulty of laborious manufacturing operations - casting, drilling holes, and the large consumption of metal materials only because of the need for the necessary weight, all of which is supported by the cost of the support. Another disadvantage of the jetvar solu- tion of the support, which does not allow for the inexpensive storage of the supports, increases the costs and demands for storage space, transport, loading and folding. Most of the above-mentioned drawbacks are eliminated by the support for lightning conductors according to the invention, which is based on a support base with a detachable fastener attached to the upper surface, more than 3/4 of the weight of the support is made of non-metallic material. weight from 0.5 g cm-3 to 5.2 g cm-3. The base of the support has a shape of the bearing surface with the formation of a cavity, or a shell of the base as well as a top surface with a projection; transport or storage. Advantages of the support according to the invention are reduced in comparison to casting from cast iron, reduced labor intensity, transport capacity and transport costs in the case of transport from a specialized manufacturer to a construction company or builder, as well as transport from building warehouses to a building site, furthermore, in a better utilization of the storage space in the storage type of the pallet-supporting supports, the multi-layer storage may be superimposed. Further advantages are in reducing the consumption of metal materials by at least seventy-five pens

Claims (3)

2 207265 cent of the total operating weight compared to the all-metal type of flat roof support, and consequently a reduction in production, sales and investment costs of lightning conductors. Corrosion resistance is improved when embedding the plastic and non-metallic storage portions. Examples of embodiments of the support are shown in the accompanying drawings, in which: FIG. 1 is a cross-sectional view of the support suitable also for the local production of a construction company, its overall configuration is shown in FIG. FIG. Fig. 4 is a front view and Fig. 5 shows a support suitable for filling the waste material filling directly at the construction site, as shown in Fig. 6. In the alternative of Figs. a support base made of molten basalt, asbestos cement, slag, compressed concrete or cinder-concrete, concrete with additives of polyvinyl acetate and filler filler from waste inorganic waste pulp, or plastic-concrete filler of waste inorganic materials. The base 1 of the support 1 has a cavity 12 'shaped on the bearing flat 11' which is identical with the projection 14 placed on the upper flat base 13 of the support 1. In the body of the support there is an opening 20 for fixing the screw 21 to the base of the support 1. one arm abuts the square foot 25 and the other arm holds the conductor 30. The square washer 25 is mounted on the protrusion 14. The screw 21 is in the cavity 12 removably attached to the support 1 by a nut 22, which is supported by a circular washer 23. can be stacked on top of each other for five to ten pellets by means of a metal tape or a transport screw through the opening 20. When mounting the conduits, the conductor 30 is clamped between the aperture 23 and the square washer 25. In the second alternative shown in FIGS. and 6, the base of the support 1 is modularly composed of a sheath substrate 15 (the base of which is placed in the base 17) of the tubular spacer 27 and the base cover 16. The filling 17 will be filled into the base shell 15 up to the point of use of the support. When shipped from the manufacturer, the base shell 15 can be inserted at least ten pieces into each other. The sheaths 15 and the base cover 16 can be made of sheet metal with corrosion protection, thermoplastic non-combustible material, fiberglass-prepreg powder. It may be OBJECT to fill the base 17 1. A support especially for lightning conductors, characterized in that it is formed from a support base (1) to which the available waste material is disassembled above the upper surface (13), located either directly on or near the site - deteriorated gravel or grit, slag , construction debris, concrete residues. The base shell 15 has a recessed space 18 and an opening in the housing 28 formed on the bearing surface 11. The base cover 16 has: an opening in the cover 26 for the screw 21. The multi-housing 16 is mounted on the base shell 15 so that it is covered and sealed. A spacing sleeve 27 is inserted between the housing 15 and the base cover 16 through which a screw 21 is mounted on which a square nut 29 is mounted above the base cover 16, where a conductor is attached to the cover 24 and the nut 22 when fixing the lightning conductor through the supports of alternative I 1, 2 and 3 are transported over at least five pieces of palletized base of support 1, a sheath is placed in place and a screw 21 with threaded tab 24a is inserted into the hole 20 and fastened to the base of support 1 in the cavity 12 The nut 30 is inserted between the shim 24 and the square shim 25, whereupon the bolt 21 is tightened, the fastening is terminated. When attaching the lightning conductor, help! 4, 5 and 6, the packed sheath of the base 15 with the lids 16 is transported at least twenty times. Even before transport to the roof, the sheath 28 is inserted into the sheath 28 and the spacer tube spacer is inserted. 27, then after; the top fills the base shell 15 with a suitable and available base 17. The base cover 16 is threaded through the opening in the cover 26 around the screw 21, seated on the base shell 15, and tightened by the square nut 29i to prevent vertical movement. The sanasunia insert 24 on the screw 21 and fastens with the nut 22. Tactosupplied supports are transported to the roof instead of the mounting. The conductor 30 is inserted between the square nut 29 and the shank 24, whereby the screw 21 is terminated. The support is particularly suitable for fastening lightning conductors on roofs with a low slope. 1, 2, 3, it is also possible to use them to fasten portable fences of pits, fence areas, lawns, flower areas, working areas for reconstruction of objects or pastures, and as holders for trapping bars mounted on the roof surface with a low slope.
