Description

Quick mounting structure of waterproof theftproof crane span structure apron

Technical Field

The application relates to the technical field of bridges, in particular to a rapid installation structure of a waterproof anti-theft bridge cover plate.

Background

The continuous development of urban construction, the cable bridge frame is convenient to assemble, disassemble and replace due to quick construction and flexible wiring, and is attractive in appearance and widely applied to large-scale industrial, public and residential electrical engineering. Along with the continuous increase of the volume of engineering, the construction side is required to design and reduce the floor elevation in order to improve the utilization rate of the building and the control of the manufacturing cost, and the building size of strong and weak electric wells is reduced, so that the bridge frame is difficult to splice and fix at the positions of strong and weak electric wells, basements, dense arrangement and the like.

The traditional bridge cover plate is installed by adopting the connection modes of clamping buckle type, clamping pressing type, screw fixing, hasp type and the like, the strength of the connecting point is not enough, the dislocation gap between the bridge and the cover plate joint is large and can not be sealed, the screw is directly fastened with the cover plate plane, and the cover plate is easy to deform and the anti-corrosion layer is easy to damage. If (1) the bridge cover plate adopts a spring clamp fixing structure, the cover plate can not be clamped and is easy to loosen by means of the self elasticity of the spring clamp, and the bridge cover plate is only suitable for horizontal installation of the bridge, and the cover plate is easy to slide from the tray during vertical installation. (2) When the clamping code and the hook nail type fixing are adopted, only when the bridge is produced, small square holes are punched on the side face of the bridge body to serve as mounting fixing points, and the conditions that the gap between the bridge and the cover plate is large, looseness is easy and the like occur after the cover plate is fixed. (3) When the hasp type structure is adopted for connection, the hasp structures on the bridge frame and the cover plate are required to be welded in advance in a factory, and the dislocation and the insufficient strength of the hasp are easy to occur. The bridge cover plate is connected and fixed in a mode, after installation, the cover plate and the bridge are often large in gap and cannot be attached, the surface is uneven, and the like, so that the bridge cover plate cannot be used outdoors, on a roof and in a waterproof and dustproof environment. The installation quality and the impression effect of the bridge frame have great influence on the engineering provide quality goods or brilliant.

Because the bridge, the cover plate and the coating are supplied with finished products, when the bridge is spliced and installed on a construction site, after the bridge is cut and fed, square holes or welding buckles cannot be formed on the bridge cover plate, the problems of insufficient strength of connecting fixing pieces, dislocation of joints of the bridge and the cover plate, large gaps and the like occur, and many projects can only fix the cover plate by using strong tapping screws as temporary remedy measures, but the quality problems of large dislocation gaps of interfaces, uneven surfaces and the like cannot be solved after the fixing, the reworking repair cannot be carried out later, and the fixing mode does not meet the requirements of electrical specifications. Because the strong tapping screw port is sharp, the cable insulation layer laid in the bridge is easy to damage after being fixed with the bridge, the cable circuit is easy to generate electric leakage and short circuit, great potential safety hazard is brought to the safe operation of an electric trunk line, the bridge and the cover plate are difficult to fasten by fixing bolts when being installed and connected in a narrow space on site, the labor and the time are wasted, safety accidents can be caused by slight carelessness, and engineering safety and integral quality are seriously affected.

Therefore, the traditional construction method is changed, the installation process which has the advantages of simple fixed structure, convenient installation, water resistance, dust resistance and effective protection of the bridge and the cable is formed, and the problem to be solved by each electromechanical installation construction unit is solved.
