Description

Technical Field

[0001] The present application relates to the technical field of bridge frames, and in particular to a waterproof and anti-theft bridge frame cover quick installation structure. Background Art

[0002] With the continuous development of urban construction, cable trays are widely used in large-scale industrial, public and residential electrical projects due to their fast construction, flexible wiring, easy loading and unloading, and beautiful appearance. As the volume of the project continues to increase, the construction party requires the design to reduce the floor elevation and reduce the size of the strong and weak electric shaft in order to improve the utilization rate of the building and control the cost, which makes it difficult to install and fix the cable tray in densely arranged areas such as the strong and weak electric shaft, basement, and corridor.

[0003] The traditional bridge cover installation adopts the connection methods of snap-on, clamping, screw fixing, buckle, etc., but the connection points are insufficient in strength, the gap between the bridge and the cover is large and cannot be sealed, and the screws are directly fastened to the cover plane, which easily causes the cover to deform and the anti-corrosion layer to be damaged. For example: (1) When the bridge cover adopts the spring clamp fixing structure, the cover cannot be clamped tightly and is easy to loosen by relying on the spring clamp's own elastic force. It is only suitable for horizontal installation of the bridge. When the bridge is installed vertically, the cover is easy to slide off the pallet. (2) When the card code and hook nail fixing are adopted, small square holes can only be punched on the side of the bridge body as the installation fixing point during the production of the bridge. After the cover is fixed, the gap between the bridge and the cover is large and easy to loosen. (3) When the buckle connection is adopted, the buckle structure on the bridge and the cover needs to be pre-welded in the factory, which is prone to misalignment and insufficient strength. The above-mentioned bridge cover connection and fixing method often has quality problems such as large gap between the cover and the bridge after installation, and uneven surface, and cannot meet the requirements of outdoor, roof and waterproof and dustproof environments. The installation quality and visual effect of the bridge have a great impact on the excellence of the project.

[0004] Since the bridge, cover and coating are supplied as finished products, when they are installed at the construction site, it is impossible to open square holes or weld buckles on the bridge cover after the bridge is cut and cut, resulting in insufficient strength of the connection fixings, misalignment of the bridge and cover seams, large gaps, and other problems. Many projects can only use strong attack screws to fix the cover as a temporary remedial measure, but after fixing, it still cannot solve the quality problems such as large interface misalignment gaps and uneven surfaces. Subsequent rework and repair are impossible, and the fixing method does not meet the requirements of electrical specifications. Since the strong attack screw port is sharp, it is easy to damage the insulation layer of the cable laid in the bridge after being fixed with the bridge, and the cable line is prone to leakage and short circuit, which brings great safety hazards to the safe operation of the electrical trunk line. When the bridge and cover are installed and connected in a small space on site, it is difficult to tighten the fixing bolts, which is labor-intensive and time-consuming. If you are not careful, safety accidents may occur, which seriously affect the safety and overall quality of the project.

[0005] Therefore, changing the traditional construction method to form an installation process that has a simple fixed structure, convenient installation, is waterproof and dustproof, and can effectively protect the bridge and cables has become an urgent problem to be solved by various mechanical and electrical installation construction units.
