As a kind of integrated pipe gallery, the cable pipe gallery has the characteristics of less investment and simple maintenance after completion in addition to some commonalities of the integrated pipe gallery, and has great advantages in urban underground pipeline laying. Therefore, the application of the cable pipe gallery is becoming increasingly widespread, and it has become an important laying carrier for pipelines such as electricity, communication, water supply and drainage, and gas. Under the action of an earthquake, the pipeline will move horizontally back and forth along with the bracket, which may cause damage to the pipeline.

The longitudinal cross - section of the upper transition section 22 gradually decreases from the upper connection section 21 towards the energy - dissipating section 23, and the longitudinal cross - section of the lower transition section 24 gradually decreases from the lower connection section 25 towards the energy - dissipating section 23.

[0035] The bracket 1 includes a vertical embedded plate 11 connected to the side wall of the pipe gallery, a horizontal bottom plate 12 with one end connected to the vertical embedded plate 11, and a stiffening rib 13 connected to the side surface of the vertical embedded plate 11 and the lower surface of the horizontal bottom plate 12. The stiffening rib 13 plays a role in improving the vertical bearing capacity of the bracket 1. The vertical embedded plate 11, the horizontal bottom plate 12, and the stiffening rib 13 are connected by welding.

[0036] Both the upper connection section 21 and the lower connection section 25 are provided with U-shaped damper installation holes 26;

[0037] The top plate 3 is provided with top plate installation holes (not shown) corresponding to the U-shaped damper installation holes 26;

[0038] The horizontal bottom plate 12 is provided with bottom plate installation holes 121 corresponding to the U-shaped damper installation holes 26.

[0039] There are at least two U-shaped dampers 2.

[0040] There are four U-shaped dampers 2, which are installed on the horizontal bottom plate 12 in a matrix arrangement.

[0041] Two U-shaped dampers 2 are parallel to the length direction of the cable, and the notches of these two U-shaped dampers 2 are arranged opposite to each other; the other two U-shaped dampers 2 are perpendicular to the length direction of the cable, and the notches of these two U-shaped dampers 2 are arranged opposite to each other.

[0042] The lower connection section 25 is detachably connected to the horizontal bottom plate 12 by a bolt installation method, and the top plate 3 is detachably connected to the upper connection section 21 by a bolt installation method.

[0043] The cable bracket 5 is two C-shaped brackets;

[0049] The installation process of the utility model is as follows: The bracket 1 can be prefabricated in the factory. During construction, the vertical embedded plate 11 is welded to the sidewall steel bars of the cable duct gallery in advance, and then concrete is poured to provide the vertical support for the bracket 1.

The cables and pipes are placed on the cable support 5.

[0050] Under the action of an earthquake, a relative displacement occurs between the cable and the bracket 1. Driven by the horizontal bottom plate 12 of the bracket 1, the energy dissipation section 23 of the U-shaped damper 2 undergoes reciprocating bending and torsion deformation, dissipating the seismic energy. At the same time, the relative displacement between the cable and the bracket 1 is reduced, thereby reducing the horizontal displacement of the cable and protecting the cable from damage. After the earthquake, the damaged U-shaped damper 2 can be conveniently replaced by disassembling and assembling the bolts.

[0051] The advantages of the utility model include: Applying the U-shaped damper to the cable support, taking advantage of the good energy dissipation performance, maintenance-free, and easy-to-replace characteristics of the U-shaped damper, it can effectively reduce the damage of earthquakes to important cables and improve the seismic performance of the cable duct gallery.
