For convenience of description, in the present invention, the bracket, the support, the spreader of the hanger, etc. for supporting the bridge body are collectively referred to as a bridge bracket, which is simply referred to as a bracket.
The cover plate of the existing bridge is manufactured separately from other parts of the bridge body, so that the laying space in the bridge can be opened and closed by installing the cover plate. The cover plate is detached to open the internal space of the bridge frame so as to facilitate the operations of laying, binding and fixing, detecting and marking and the like of the cable, and the cover plate is attached to seal the bridge frame and protect the cable.
The existing bridge system is usually built by building foundation structures such as cable trenches, frames and the like; firstly, mounting a bracket arm on the side vertical surface of the built cable trench, the top surface of the frame and the like; and then, the bridge assembly is processed and installed on site, and the bridge assembly is arranged on the support arm. And laying cables after the bridge frame is assembled. The cable is drawn to pass through each section of bridge frame and the bracket or the hanger in sequence, is arranged in the bridge frame according to the specification, and is bound and fixed; and covering the cover plate, and binding and fixing the cover plate.
The cover plate has the functions of protecting and decorating the cable, and is convenient to mount and dismount so as to facilitate the inspection and maintenance operation of the cable. Sufficient space is required inside and around the tray to facilitate cable addition or removal.
However, the work can be completed in a local area of the bridge, the cover plate is large in size, low in rigidity and easy to warp and deform due to the structure that the cover plate is separated from the groove box, the cover plate is not easy to align and fix during installation, the cover plate is often warped and deformed during disassembly, and the processing, installation and maintenance cost is high.
In the direction along cable laying, only in the interval that needs operate the cable, the apron that sets up can the dismouting can satisfy actual engineering needs, and the apron size can reduce, makes its rigidity grow non-deformable and the dismouting of being convenient for. In the interval without the cover plate, the bridge body can adopt a circumferentially closed box-shaped beam structure with higher rigidity and strength. Because the size of the window for installing the cover plate and the size of the cover plate are smaller, the connection is firm, the bridge frame body structure system becomes an integrally closed box-type beam structure system, and the bridge frame is high in integral rigidity and strength, large in bearing capacity, straight and neat.
