Anti-bending structure to protect underground cables in apartment houses

摘要

The present invention is in the form of a square frame to support the underground cable (1), and at the front end, the male connection part (221a) of the other underground cable support (200a) on the front side is inserted and seated with a seating groove (211) that is screwed together. The formed female connecting rod 210 is provided, and at the rear end, a male connecting rod 220 formed to protrude a male connecting portion 221 bound to the female connecting rod of another underground cable support on the rear side is provided, and the seat 201 and a support plate 200 on which a fastening screw 230 is formed to protrude upward; A rail bar formed integrally with the support plate at a predetermined interval between the female connecting rod 210 and the male connecting rod 220 of the support plate 200, and having long long hole-shaped rail holes 310 on the left and right sides in the left and right directions. (300) and; While being assembled to the rail hole 310 of the rail bar 300 in a screw method, the left and right sides of the underground cable 1 are supported, and the position of the underground cable 1 is movable along the rail hole 310 . Including the left and right support rods 400 for custom support according to the diameter, the female connection rod 210, the male connection rod 220 and the rail bar 300 are formed so that the central part thereof is curved or inclined downward. Underground cable support 100, which is further configured to prevent the underground cable 1 seated on it from being rolled off; Anti-settling mesh mat 500 connected to one side and the other side of the support plate 200, respectively; It serves to cover the upper portion of the support plate 200 and the support plate 200a connected to the front thereof, and the fastening screws 230 and 230a formed on the two support plates 200 and 200a are penetrated at both edges by the nut n. a fastening piece 610 in which a fastening hole 611 to be bound is formed; a cover plate 620 provided between the two fastening pieces 610 and having an upwardly convex tunnel shape; a cover member 600 comprising a ball hole 630 formed at a predetermined interval on the upper portion of the cover plate 620; And while being compressed between the upper surface of the underground cable (1) and the ball hole 630 of the cover member 600, the air ball 700 for pressing the upper portion of the underground cable (1) to prevent the flow of the underground cable ; but, the outer diameter of the air ball 700 is formed larger than the hole diameter of the ball hole 630 formed in the cover plate 620, so that the air ball 700 does not fall out through the ball hole 630. It relates to a bending prevention structure for protecting the underground cable of the apartment house, which further includes a part of the ball inserted into the ball hole to prevent separation. The present invention has an uncomplicated structure and easy construction, relatively low material cost and construction cost, can effectively prevent bending of an underground cable due to external impact, etc. By preventing the subsidence of the underground cable, there is an effect that can also prevent the subsidence of the conduit located above the underground cable in advance.
