ROOF CONDUCTOR HOLDER

Abstract

A roof-mounted conductor holder is part of a lightning protection system installed on flat-roofed buildings and designed to prevent direct lightning strikes. The use of a roof-mounted conductor holder, which consists of a plastic housing with recesses designed to accommodate the down conductor and a cover secured to the housing by a weld (either ultrasonic, laser, or thermal). The replacement of concrete filler with a loose filler such as sand, gravel, or slag increases the reliability of the conductor holder.

Description

[0001] The device being declared is a roof conductor holder, which is part of a lightning protection system located on buildings with a flat roof and designed to prevent a direct lightning strike to the building.

[0002] A roof conductor holder (hereinafter referred to as the holder) is an element of the lightning protection system that is attached to the roof, on the upper surface of which, in turn, a down conductor is attached, made in the form of a round or strip conductor.

[0003] The prior art includes holders produced by various manufacturers, on the surface of which conductors with a diameter of 8 or 10 mm are fixed (see https: / / ezetek.ru / produkciya / sistemy-molniezaschity / komplektuyuschie / derzhateli / 91053, for example, the manufacturer EZETEK https: / / www.iek.ru / products / catalog / sistemy_dlya_prokladki_kabelya / molniezashchita_i_zazemlenie / passivnaya_molniezashchita_i_zazemlenie / derzhateli / derzhatel_provodnika_kruglogo_8mm_dlya_ploskoy_krovli_plastik_s_betonom_iek), which are made as follows.

[0004] The EZETEK holder is made of a plastic housing and a lid that fits onto the housing from below. The interior of these holders is filled with concrete.

[0005] The disadvantages of such holders are the use of concrete as a filler and the weak connection of the body with the lid.

[0006] When poured, concrete has a viscous consistency that changes over time, making it difficult to automate the process of filling the housings. Moreover, the edges of the housings are often stained with this concrete and do not have a tight connection with the lids.

[0007] The concrete used as filler in the holders is typically weak. As a result, during use, the concrete filler deteriorates due to the thermal expansion of the water and the contraction of the concrete due to exposure to the external environment and water remaining in the concrete itself. A poorly secured cover eventually becomes detached from the body. Under the influence of the external environment, the deteriorated concrete spills out of the holder, resulting in the holder becoming poorly secured to the roof and failing to perform its intended function.

[0008] The production of known holders includes sequentially performed operations: the production of concrete, its pouring into the body of the retainer, closing this body with a lid.

[0009] Considering concrete's viscous nature and its hardening over time, pouring it into the small plastic housing of the holder is problematic. Therefore, concrete is most often poured manually. Another drawback of the well-known concrete holders is that they require a dedicated facility with specialized equipment, including water and sewer lines, and additional storage space.

[0010] The technical result of using the claimed technical solution is increased reliability of the holders due to the fact that the filler in the holders is loose materials—such as sand, fine gravel, small pebbles, and slag—which do not disrupt the connection between the body and the lid. Furthermore, these fillers do not expand or degrade at low temperatures.

[0011] The body and cover are connected by a welded seam, which is made using either ultrasonic, laser or thermal welding, as a result of which the connection of the cover and the body is much more reliable than that of the analogue.

[0012] At the same time, the declared holders have lower production costs due to the elimination of the concrete production section and automation of filler filling.

[0013] DESCRIPTION OF ROOF CONDUCTOR HOLDERS

[0014] The figure shows a sectional image of the holder, where:

[0015] 1 - Holder body,

[0016] 2 - Filler;

[0017] 3 - Cover;

[0018] 4 - Seam.

[0019] A roof conductor holder made in the form of a plastic housing with recesses intended for laying a down conductor, and a cover fixed to the housing, where the housing and the cover have a contact connection made by means of a welded seam, while the interior space of the conductor holder has a filler in the form of sand.

[0020] The seam can be made by either ultrasonic, laser or thermal welding.

[0021] The production of these holders is automated.

[0022] Plastic housings and covers are produced by molding.

[0023] On the automated line, sand weighing 1000 ± 25 g is poured into the cavity of the housing, then the covers are put on the housing and welded to it.

[0024] The finished holders are packed and sent to their destination.

2. A roofing conductor holder according to paragraph 1, characterized in that sand is used as a filler.

3. A roofing conductor holder according to paragraph 1, characterized in that pebbles are used as filler.

4. A roofing conductor holder according to paragraph 1, characterized in that slag is used as a filler.

5. A roofing conductor holder according to paragraph 1, characterized in that the weld seam is made by ultrasonic welding.

6. A roofing conductor holder according to paragraph 1, characterized in that the weld seam is made by laser welding.

7. A roofing conductor holder according to paragraph 1, characterized in that the weld seam is made by thermal welding.

8. A roofing conductor holder according to paragraph 2, characterized in that the weight of the sand poured into the holder is 1000±25 g.
