An easy-to-install cable tray

Abstract

The invention relates to a cable bridge convenient to install and relates to a cable bridge. A top plate (2) is provided with a plurality of installation holes (1) at intervals, vertical plates are arranged on the lower portions of the two sides of the top plate respectively, inward-folding plates (5) are arranged on the parts, close to the lower portions, of the two vertical plates respectively, corresponding insertion holes (4) are formed in the two inward-folding plates at intervals, vertical rods (9) are arranged on the lower portions at the two ends of each supporting rod (8) and inserted in the corresponding two insertion holes, a cable containing space is formed between the upper portions of the supporting rods and the top plate, and inward flangings (11) are arranged on the two sides of a bottom buckling plate (10) and are clamped to outward flangings (7) arranged at the lower ends of the two vertical plates. According to the cable bridge convenient to install, the supporting rods which are movably connected in an insertion mode are used for replacing existing welded and integrated steel plates, a cable does not need to be cut off in the construction process, and the purpose of electrified construction is achieved.

[0004] It is known that the cable tray is mainly used for laying cables on the building, and the cable can be closed on the building through the cable tray. format and other structures; cable trays use brackets, brackets and installation accessories where conditions permit, and use cable trays to avoid accidents from being exposed to cables and being directly contacted by other objects; cable trays can be installed in bridges and culverts. To reduce secondary damage to buildings without cable trenches, "cutting grooves on buildings to hide cables" also has aesthetic effects; but the existing cable bridge structures suitable for installation at the bottom of bridges and at the top of culverts are channel steel, By fixing the channel-shaped cable tray on the bottom of the bridge or the top of the culvert, the steel plates on both sides of the connection wall are welded at intervals at the lower opening. When in use, the cables are inserted into the channel-shaped cable tray on the upper part of the steel plate, and then use the plug-in bottom plate Close the lower opening. The use of this structure must disconnect the cable close to the bridge or culvert, and then connect the disconnected part of the cable after the construction is completed. In the operation of loading the old cable into the cable bridge, it is necessary to cut off the power. Therefore, the construction steps are cumbersome
