Description

Technical Field

[0001] The utility model relates to the technical field of cable trays, and more specifically, to a lightweight and high-strength plastic-steel cable tray. Background Technique

[0002] Cable trays are divided into trough type, tray type, ladder type, grid type and other structures. Cable trays in buildings can be erected independently or laid on various building (structure) buildings and pipe gallery supports. They should reflect the characteristics of simple structure, beautiful shape, flexible configuration and convenient maintenance. All parts need to be galvanized. For cable trays installed outdoors of buildings, there are many kinds of materials for cable trays. Because plastic-steel has the advantages of light weight and high strength, cable trays made of plastic-steel are widely used.

[0003] Existing plastic-steel cable trays are usually of an integral rectangular pipe rack structure, which occupies a large space. Therefore, when transported by vehicles, the stacking quantity in the carriage is limited, which is not conducive to the large-scale transportation of plastic-steel cable trays. At the same time, because the wall thickness of the cable tray is relatively thin, when stacked in the carriage for transportation, the pressure on the plastic-steel cable trays stacked at the bottom of the carriage increases, and it is very easy to be deformed by pressure. In view of this, we propose a lightweight and high-strength plastic-steel cable tray. Content of the Utility Model
