Description

Technical Field

[0002] Cable trays are commonly used in construction projects. They are used to lay and support cables inside and outside a building and are a crucial component of a building's electrical system. Cable trays effectively organize, protect, and support power cables and weak current cables within a construction project.

[0003] There are many types of bridge structures on the market. For example, a bridge for construction engineering is disclosed on the China Patent Network, with the announcement number CN209948562U. This bridge can flexibly change the internal space structure, save the space occupied by cable laying, and is suitable for different projects. However, there are some defects and deficiencies that need to be improved: (1) Due to the structural design of some existing bridges, it is difficult to arrange cables in layers. When weak current and strong current cables are mixed, it is easy to cause signal interference and failure; (2) Some existing bridges have poor extensibility and it is difficult to flexibly combine the bridges according to the laying length of the cables, making the bridges unable to adapt to the installation requirements of different occasions, thereby increasing the time and cost of on-site processing; (3) Some existing bridges are relatively closed inside. In situations where the cable load is high, the heat dissipation performance of the bridge is insufficient, and the internal heat is difficult to be discharged in time, which easily leads to overheating of the cable, thereby affecting the safety and service life of the cable. Therefore, in response to the above problems, the bridge for construction engineering provided by the utility model is of great significance. Utility Model Content
