VERTICAL ANGLE TRUNKING for laying the power and control cables and wires

摘要

The proposed utility model for vertical duct angular rotation of the cable route (hereinafter - the corner box) refers to electrical engineering and can be used to route cables and wires of various purposes by turning the vertical cable tray 90 or 45 degrees up or down. The technical result of the proposed utility model solved is to improve the reliability of the design angular vertical duct. This is achieved in that the vertical angular box comprising a body and a lid made of a monolithic strip by bending to form a base and side walls, the box body has a non-closed angular cross-sectional profile. The side wall of the housing box corner in the upper vertical parts are provided with U-shaped bends, as well as the two sides are symmetrically arranged openings intended for joining cable tray boxes together. The base housing box corner with two vertical sides provided with grooves oval. Further, in the corner of the vertical duct structure introduced symmetrical clamping bar designed as a rectangular metal plate with a thickness greater than the thickness of the side walls box body corner at least twice, located inside the housing box corner with two sides and having a central opening. Symmetrical clamping bar is made with the possibility of regulation of its location with a washer and nut. Further, in the corner of the vertical duct introduced construct threaded rod mounted in the beginning and the end of the duct corner and adapted to be fixed at its lower end through oval slots base housing corner box by a threaded connection. Additionally, for the vertical and angular tie box lid body inserted threaded rod installed on both sides (at the beginning and at the end) and a box representing the axis with metric thread on two sides. Such installation of the threaded rod increases rigidity angular vertical duct which leads to an increase in mechanical strength, and thus reliability in operation box corner. On the threaded rod fastened cover, which is also fixed by a threaded connection and is formed of a monolithic strip by bending at a right angle to form side walls and a base. The presence of the threaded rod in the design unifies and simplifies the assembly of the vertical duct corner. Furthermore, as a monolithic strip material of the box parts, carbon steel is used. All surfaces of the parts bin angular vertical have corrosion protection in the form of paint coating thickness of at least 50 microns or coating metal - hot dip galvanizing at least 80 microns thick, or a combination coating of a paint and the metal - hot-dip galvanized with a thickness of respectively 50 mm and 80 um or paint based on epoxy enamels. Angular vertical duct for routing power and control cables and wires may be formed with a perforated base and cover.
