Description

Technical Field

[0001] The utility model relates to the technical field of cable construction, in particular to a cable bridge for building electrical construction. Background Art

[0002] In building electrical engineering, the electric shaft is a relatively narrow space with relatively dense cables, wires, cable trays, and distribution cabinets. Due to the narrow space, it is sometimes difficult to carry out the construction and operation and maintenance of the cable tray in accordance with the specifications, which can easily cause damage to the cables. In addition, the entire electric shaft is relatively messy, with a bad appearance and potential safety hazards. The cable tray is divided into trough type, tray type, ladder type, grid type and other structures, and is composed of brackets, brackets and installation accessories. It can not only be installed independently through the bridge, but also installed on other buildings or brackets. It is easy to disassemble and assemble, and can provide all-round protection for the cables. It is frequently used in factories and construction sites. It can also be laid on various buildings and pipe gallery brackets. It should reflect the characteristics of simple structure, beautiful shape, flexible configuration and convenient maintenance. All parts must be galvanized. The bridge installed in the open air outside the building is divided into trough type, tray type, ladder type, grid type and other structures. It is composed of brackets, brackets and installation accessories.

[0003] With regard to the existing cable bridge, when installing the cable bridge, since the required lengths of the cable bridge are different and the specifications of the cable bridge are different, the cable bridge needs to be assembled and fixed according to the construction requirements. During the assembly, several sections of the cable bridge need to be butt-jointed together. When butt-joining the cable bridge, the two sections of the cable bridge need to be aligned first, and then the two sections of the cable bridge need to be fixed by connecting parts. However, since the cable bridge is prone to displacement, when fixing the cable bridge, the assistance of others is required to fix the cable bridge, which is inconvenient during installation and wastes manpower. In addition, the air entering the cable bridge during use may contain dust and other impurities. The accumulation of impurities will affect the heat dissipation of the cable and may cause safety accidents. In this regard, in order to solve this technical problem, the present application proposes a cable bridge for building electrical construction. Utility Model Content
