Problems solved by technology

[0003] The basement cable tray of Beichen Hanjiashu project is installed on the basement roof, and the clearance of the basement is 3.8m. Due to the high height, it will take time and effort to install the boom with sliding scaffolding, and there will be many high-altitude operations, which will be more dangerous
[0004] Therefore, there are above-mentioned inconveniences and problems in the known basement cable tray installation method

Embodiment 1

[0033] The cable bridge suspender installation method of the present invention comprises the following steps:

[0034] 1. Positioning of snapping lines: According to the design drawings, determine the installation positions of electrical appliances such as entry and exit lines, boxes, boxes, cabinets, etc., find out the horizontal or vertical lines, and perform snapping lines on the center line of the lines, and determine the drawings and specification requirements to determine each Mark the center position of the expansion bolt of each qualitative bracket.

[0035] 2. Design drilling tools for reserved holes for expansion screws

[0036] see now figure 1 , figure 1 It is a schematic diagram of the wooden frame structure of the drilling tool according to the embodiment of the present invention. As shown in the figure, the wooden frame of the drilling tool is made of 50mm wooden square as the upper and lower poles. The movable arm and the manual support arm are used to conne...

The cable bridge suspender installation method of the invention has the advantages of simple structure of the drilling tool, convenience to manufacture, reasonable design of the cable bridge suspender, convenience for construction, safe and reliable engineering quality, avoidanceof working at heights, improvement of the work efficiency, saving of the construction period and the construction cost and reduction of the engineering cost.

Description

technical field [0001] The invention relates to a cable bridge, in particular to a method for installing a suspension rod of a cable bridge. Background technique [0002] The bridge is a kind of supporting part for laying cables. It is relatively simple to install and convenient to repair and renovate. It is widely used in strong and weak current projects. Cable trays are generally divided into three types: trapezoidal, trough, and tray. All the bridges of this project are trough bridges. The inner and outer surfaces of the bridge frame are all electroplated. The cable bridge is in the stereotyped bracket. The stereotyped bracket consists of two parts: a three-piece set of expansion bolts, a boom and a support arm. The suspension rod is fixed on the beam or roof with steel expansion bolts, and the support arm is fixed on the suspension rod. [0003] The basement cable tray of Beichen Hanjiashu project is installed on the basement roof, and the clearance of the basement is...
