Embodiment 1
[0038] The quick installation device for the supporting arms of cable trays in rows of underground pipe corridors includes a main body assembly 1 and a fixed arm assembly 2. The main body assembly 1 includes a C-shaped channel steel 11, a scale 12 and a magnetic block 13. The length of the scale 12 is Slightly less than the length of the C-shaped channel steel 11, the fixed arm assembly 2 includes a fixed arm 3, a cable tray support arm 4, special-shaped bolts 5, washers 6, nuts 7 and locknuts 8;
[0039] The scale 12 is between the C-shaped channel steel 11 and the magnetic block 13, and the scale 12 is fixed on the side of the C-shaped channel steel 11 by the magnetic block 13;
[0040] One end of the fixed arm 3 is vertically fixedly connected with a fixed plate 31, and the fixed plate 31 is respectively provided with through holes 32 on both sides of the upper and lower parts of the fixed arm 3, and the cable tray support arm 4 is fixedly connected to the fixed arm. 3 lowe...
Embodiment 2
[0055] The difference between embodiment 2 and embodiment 1 is that the groove on the tail end surface of the special-shaped bolt 5 is a cross-shaped groove.
[0056] The present invention proposes the quick installation device for the support arm of the cable bridge in rows in the underground pipe gallery and the beneficial effects of the use method thereof are as follows:
[0057] (1) Speed up the construction progress: the same as the conventional method, use the control line first, and then use a steel tape measure to measure the distance and compare the installation layer by layer. Through the use of special installation devices, all the brackets in the entire pipe gallery can be installed at one time. There is no need to control the layer spacing of the support arms one by one, which greatly improves the working efficiency.
[0058] (2) High economic benefit: adopting this method can save a large number of construction personnel costs and save engineering construction ...
