[0035]Example 1:
[0036]Such asFigure 1-3As shown, a bridge with intermittent holes includes at least one set of bridge tubes 1 with intermittent holes on the surface of the bridge tube 1, and at least one set of openings has a cover plate assembly 3 on the surface, and the cover plate assembly 3 is connected to the bridge frame through a connector 2 The tube 1 is connected, and the cable 7 is located inside the tube 1 of the bridge frame.
[0037]The bridge tube 1 has a box-shaped structure and can be made of various materials such as metal materials such as steel plates, aluminum alloys, or organic polymer materials such as polyvinyl chloride, or composite materials. Preferably, polymer materials and their alloys are made by extrusion method, and holes are made on each surface of the bridge tube 1 in the circumferential direction after forming.
[0038]The opening can be used as a ventilation hole, and it can also be used for pulling and laying cables, binding and fixing cables, checking ...
