Problems solved by technology

[0002] As we all know, cable bridges are generally suitable for large-scale engineering transformation of large enterprises, cable erection, large bridges, subway cable laying, and offshore drilling. There is a common defect in cable trays, that is, at the fire scene, the cable trays used as carrying cables cannot effectively prevent fire damage to cables, and further cause greater safety accidents. Therefore, an effective fireproof type is developed. Cable tray is imminent

Abstract

The invention relates to a fireproof cable bridge which comprises a cover plate, two C-shaped side plates with corresponding openings, a first phenol resin plate, two second phenol resin plates and a third phenol resin plate, wherein the first phenol resin plate is transversely paved on the upper end surfaces of installation portions of the C-shaped side plates, and a base plate is arranged on the upper end surface of the first phenol resin plate. A protrusion portion is arranged on the upper end surface of a supporting portion of each C-shaped side plate, a corresponding groove is arranged on the lower end surface of each supporting portion at the position corresponding to the protrusion portion, the cross sections at the upper ends of the second phenol resin plates in the longitudinal direction are matched with the grooves, and the lower end surfaces of the second phenol resin plates butt against the upper end surface of the base plate. Steps are formed between corresponding lateral sides on the supporting portions of the two C-shaped side plates and respective protrusion portions respectively, and two sides of the third phenol resin plate are in lap joint with the steps respectively. The fireproof cable bridge has a fireproof effect due to the fact that the phenol resin plates have good heat isolation and fireproof performances.

Description

technical field [0001] The invention relates to a cable laying device for erecting and protecting cables, in particular to a fire-resistant cable tray applied to a large bracket span. Background technique [0002] As we all know, cable bridges are generally suitable for large-scale engineering transformation of large enterprises, cable erection, large bridges, subway cable laying, and offshore drilling. There is a common defect in cable trays, that is, at the fire scene, the cable trays used as carrying cables cannot effectively prevent fire damage to cables, and further cause greater safety accidents. Therefore, an effective fireproof type is developed. Cable tray is imminent. Contents of the invention [0003] The object of the present invention is to overcome the defects of the prior art and provide a cable tray with simple structure and effective fire prevention. [0004] In order to achieve the above object, the present invention adopts a fire-proof cable tray, incl...
