Trace-type light cable bridge frame

Abstract

The invention discloses a trace-type light cable bridge frame which is composed of a baseboard and side boards, wherein two edges of the baseboard are respectively fixed on the inner sides of the lower bottom edges of two side boards; the baseboard or each side board is provided with concave spots with the size of 1-5mm and the depth of 0.2-2mm; the cross section of each concave spot is a circle, or an oval or a square; and the concave spots are arranged in rhombic, square, oblong or other patterns or words. The cable bridge frame adopting the above structure increases intensity, lowers the thickness of the bridge frame sheet material under the same intensity, lowers dead weight and lowers cost.

Description

technical field [0001] The invention relates to a cable bridge used for routing electric power or communication cables, in particular to a trace-type lightweight cable bridge with concave points on the surface. Background technique [0002] At present, the bridges produced in China generally use cutting, folding, punching and electric welding to machine the metal plates to shape them. In order to meet the load-bearing requirements, the deflection of the bridges should not exceed 1 / 200. The size of the bridges is determined according to the amount of cables laid. Size, metal plates require different thicknesses respectively. The disadvantage of this kind of bridge is that the strength is low, and the metal plate used in the high-strength bridge is too thick and the weight is too heavy. Contents of the invention [0003] The object of the present invention is to provide a cable tray with light weight, low cost and high strength. [0004] In order to realize the technical p...
