Description

Technical Field

[0001] The utility model relates to the technical field of slot-type straight-through bridge frames, in particular to a slot-type straight-through bridge frame which is easy to disassemble. Background Art

[0002] Trough type straight-through bridge is a device used for cable laying. Its function is to lay wires in a centralized manner and protect them from mechanical damage and other hazards. The following are some of the main features and advantages of trough type straight-through bridge: Structural features: Trough type straight-through bridge is made of a whole steel plate bent with a specific depth and closure. Compared with the tray rack, its height-to-width ratio is different. The tray rack is usually shallow and wide. The straight-through bridge is mainly composed of straight sections, bends, components, brackets (arm-type brackets), hangers, etc. of trays or ladder racks, forming a rigid structural system with close-fitting support cables. The structural design of the trough type straight-through bridge makes it very convenient to install and disassemble, and does not require the use of bolts and other connectors.
