Description

The utility model relates to the sectors of the national economy: electric power and communications. Specifically, to the construction of the traverse, which, mainly, can be used for fastening overhead communication lines and overhead power lines at the corners of houses and other buildings located at the nodal points of intersection of overhead communication lines and overhead power lines.

A two-tier rack is known for fastening overhead communication lines and isolated overhead power lines on pitched and flat roofs of low-rise buildings located at nodal intersections of overhead communication lines and isolated overhead power lines (see patent RU 188531 U1, Е04Н 12/24 (2019.02 ), published on April 16, 2019 Bull. No. 11), which is arranged in the form of two parallel rectangular frames connected by jumpers at the corners, anchor brackets are fixed around the frame perimeter for fastening communication lines or s power, the two frames are mounted on towers, still connected at the corners of the structure on the bottom of each leg there is a need for fixing the roof, as well as the anchor point for safety work at height and clamp with bolt for the grounding conductor.

The closest technical solution is a two-tier traverse on a support (see patent RU 185033 U1, Е04Н 12/24 publ. 11/19/2018 Bull. N32), including a rectangular frame, the anchor brackets are fixedly mounted around the perimeter, the crossbar is fixedly fixed in the middle in the middle of the frame made of an angular profile and intended for fastening the traverse to the support, guides made of an angular profile are perpendicularly and motionlessly fixed in the middle of the crossbeam, a stiffener made of an angular profile and connected to the inside of the frame fixed with the frame structure and the crossbar, the frame is attached to the support with a collar using bolts additionally includes a lower frame with anchor brackets connected to the upper frame and the crossbar with jumpers from the angular profile and attached to the support.

However, this two-tier traverse on the support cannot structurally be fixed to the corner of a house or other structure, since the structural fastening of this traverse is intended for fastening to the support. And in places where there is dense building with low-rise houses, the corner of the house can be the place through which you can transit overhead communication lines and isolated overhead power lines without installing a support.

The objective of the proposed utility model is the creation of an angular traverse, which is designed to mount overhead communication lines and isolated overhead power lines at the corners of houses and other buildings located at the nodal points of intersection of overhead communication lines and isolated overhead power lines. The need for a real utility model arises in places where there is dense development of houses and other structures, there is no place for poles, it is not impractical to lay underground communication lines and power lines.

The essence of the utility model is that the angular traverse, including two parallel semicircular frames connected to each other in the middle and at the ends by jumpers, anchor brackets are fixedly mounted around the frame perimeter for fastening communication lines and power lines, on the inside of the frames for mounting them at an angle Brackets are installed at home.

The technical result of this utility model is to create a design for the simultaneous attachment of overhead communication lines and isolated overhead power lines, which can be fixed on the corner of the house (structure) using brackets located around the perimeter of semicircular frames.

In accordance with paragraph 2.4.39 of the Rules for the Installation of Electrical Installations (PUE 7th edition, chapter 2.4, approved by order of the Ministry of Energy of Russia dated 05.20.2003 N 187) "... metal structures and reinforcement of reinforced concrete support elements must be connected to the PEN conductor". Thus, the metal beam must be connected to the PEN conductor. Therefore, in the design of the traverse, a point of its attachment to the grounding conductor and further to the ground electrode is needed.

In accordance with the Rules on labor protection at work at heights, approved by Order of the Ministry of Labor of Russia dated March 28, 2014 N 155н (as amended) installation, operation, and repair of communication lines and power lines which are carried out at a distance of less than 2 m from unshielded height differences more than 5 m on the roofs in the absence of protective fences or with a height of protective fences of less than 1.1 meters will relate to work at heights. To ensure the safety of work, it is necessary to apply a system for ensuring the safety of work at height. The safety system for work at heights consists of: a) an anchor device; b) harness (safety harness, for holding, for positioning, for sitting position); c) a connecting-damping subsystem (slings, ropes, carabiners, shock absorbers, a retractable type of protection, a slide type of fall protection on a flexible or rigid anchor line). The simplest and most logically correct solution is to use a corner beam as an anchor device for attaching protection from falling from a height. Therefore, in the design of the corner beam, a structural element is necessary - an anchor point.

A utility model is illustrated in the drawing, where in FIG. 1 shows a general view of the corner beam.

The angular traverse consists of two semicircular frames, the upper 1 and lower 2, connected in the middle and corners by jumpers 3 and made of an angular profile. Along the perimeter of the frames 1 (upper) and 2 (lower), the anchor brackets 4 are fixedly fixed for fastening the fittings of overhead communication lines and overhead power lines. The whole structure is fastened with brackets 5 located on the inner part around the perimeter of the semicircular frames. On each jumper 3 there is an anchor point 6 for fastening the means of protection against falling from a height and on one of the brackets 4 a clip with a bolt 7 is fixedly mounted for attaching a grounding conductor. The brackets 5 for mounting are T-shaped in order to securely attach to the corner of the structure. The brackets 5 to the structure can be fixed in various ways depending on the structure of the surface 8 (anchor bolt, dowel - nail, etc.).

The device operates as follows. Two identical frames 1 and 2 of a semicircular shape, located between each other at a distance of 0.5 meters or 1.5 meters, (depending on the fastening of the wires of the overhead lines and drugs and LPV). The presence of two parallel frames 1 and 2 provides the ability to mount overhead lines of communication and overhead power lines, increases the throughput on the corner of the traverse and that ultimately organizes these lines. The presence on the inner part of the semicircular frames 1 and 2 of the brackets 5 makes it possible to set the corner beam to the corner of the house (structure). Anchor brackets 4 allow you to fasten various types of wire clamps. The crosshead design allows you to lay wires through it in any direction (transit, angular, perpendicular). A clamp with a bolt 7 is fixedly mounted on one of the brackets 5 for attaching a grounding conductor. Further, the ground conductor is fixedly connected to the ground electrode. The presence in the design of the angular crosshead of the clamp with a bolt 7 for attaching a grounding conductor, if necessary, provides electrical safety for workers, as well as technological protection from electric current. The presence on each jumper 3 of anchor point 6 for fastening protective equipment for workers from falling from a height will allow employees to insure themselves for them when performing installation, maintenance and repair work of communication lines and power lines, if necessary.

The corner beam is installed on the corner of the house (building). The corner beam is fastened through brackets 5 with fasteners 8. Brackets 5 can be fixed to the structure in various ways, depending on the surface structure (anchor bolt, dowel - nail, etc.).

The need for this design arises in places where there is dense building houses (structures). There is no place for towers of overhead communication lines and overhead power lines, it is not impractical to lay underground communication lines and power lines.
