Novel separate rail tray cable bridge frame

Abstract

The invention discloses a novel separate rail tray cable bridge frame comprising two bridge frame bodies, two bridge frame cover plates and a plurality of first fixing plates. The bridge frame cover plates are engaged and connected on the top end of the bridge frame bodies. A plurality of second fixing plates are fixedly arranged at the bottom of the two sides of the bridge frame bodies. A plurality of second fixing plates are equally spaced on the two sides of the bridge frame bodies. A first through hole is arranged in the top of each of a plurality of first fixing plates. A screw column isfixedly arranged in the middle of the bottom end of each of a plurality of first fixing plates. The separation partition plate is arranged and the cables inside the bridge frame bodies are grouped, and the cables of the same transmission type are grouped together so as to avoid the mutual interference between the cables of different types. The flame-retardant separation plate can effectively blockthe spread of the fire, avoid the spread of the fire inside the cable bridge frame and then can effectively control the fire and can effectively ensure the safety of life and property.

Description

technical field [0001] The invention relates to a cable bridge, in particular to a novel rail-divided tray-type cable bridge. Background technique [0002] Cable trays are divided into trough type, tray type, ladder type, grid type and other structures, and are composed of brackets, supporting arms and installation accessories. The bridge frame in the building can be erected independently or laid on various buildings and pipe gallery supports. It should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts need to be galvanized and installed in the building. An open-air bridge. [0003] Most of the existing cable trays have a straight-through structure inside, and generally there is no separation partition, and all the cables inside are mixed together, which is easy to cause fire and other disasters. In addition, most of the existing cable trays have no flame retardant inside In this way, if a fi...

Problems solved by technology

[0003] Most of the existing cable trays have a straight-through structure inside, and generally there is no separation partition, and all the cables inside are mixed together, which is easy to cause fire and other disasters. In addition, most of the existing cable trays have no flame retardant inside In this way, if a fire occurs in a certain part, the entire fire will spread rapidly, which may cause the cables on the entire line to be burned, and may also cause a more serious fire.
