The invention discloses a bracket used for underground section cable laying of a rail transit. The bracket comprises a bracket body and a bracket frame erected on the bracket body, wherein the bracket frame comprises two strip-shaped steel angles which are arranged in parallel at intervals and perpendicular to the bracket, two steel angle connecting plates which are positioned on the end parts of the two ends of the two strip-shaped steel angles respectively, and two groups of steel angle and bracket connecting steel plates arranged below the strip-shaped steel angles, wherein each steel angle connecting plate is used for connecting the corresponding end parts of two strip-shaped steel angles to jointly form a quadrilateral framework; the number of each group of steel angle and bracket connecting steel plates is two, and the two steel angle and bracket connecting steel plates are correspondingly arranged below the corresponding strip-shaped steel angles and positioned on the two side surfaces of the bracket body; and the strip-shaped steel angles are fixedly connected with the bracket body through the steel angle and bracket connecting steel plates. The bracket disclosed in the invention can further support the cable through the two end parts which protrude in a rail direction, by virtue of the optimized structure and improved design, so as to satisfy the span requirement of the cable bracket; and in addition, the bracket is simple and convenient in construction, simple to maintain, and capable of saving much bracket cost.
Description
technical field [0001] The invention belongs to the technical field of rail transit cable laying engineering, and in particular relates to a support for laying cables in underground sections of rail transit. Background technique [0002] In the cable laying project in the underground shield section of rail transit, it is generally used to drill holes in the segments to fix the cable brackets, and fix the cables above the brackets. According to the requirements of Chapter 15.4.3 of the "Code for Design of Metro" (GB50157-2013), the maximum allowable span of the power cable cable support is 1000mm, and the maximum allowable span of the control cable cable support is 800mm. [0003] At present, segment pre-embedded chute technology has been gradually adopted in the segment design of the underground shield section of rail transit in many cities in China. Since the segment width is generally 1500mm, the chute spacing is also 1500mm. If only one cable support is installed on one ...
