Description

Technical Field

[0001] This utility model belongs to the field of steel truss technology, specifically relating to a double-panel planar steel truss composite structural system for concrete beam formwork. Background Technology

[0002] Currently, existing ordinary steel trusses are composed of a single top chord, two bottom chords, and a web reinforcement on each side. However, this results in a large amount of material consumption and high cost in manufacturing steel trusses, which is not conducive to their use. Therefore, we propose a double-frame planar steel truss composite structure system for concrete beam formwork. Utility Model Content

[0003] The purpose of this invention is to provide a double-frame planar steel truss composite structural system for concrete beam formwork, in order to solve the problem mentioned in the background art that existing ordinary steel trusses are composed of a single top chord, two bottom chords, and one web member on each side, which results in high material consumption, high cost, and is not conducive to use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a double-panel planar steel truss composite structural system for concrete beam formwork, comprising a truss, transverse reinforcement and longitudinal reinforcement. The truss includes a flared end, an upper chord, a lower chord and web reinforcement. The transverse reinforcement is located at the lower end of the lower chord, and the longitudinal reinforcement is located above the transverse reinforcement.

[0005] Preferably, the upper chord is located above the lower chord, the web rib connects the upper chord and the lower chord, and the flared end is located on one side of the lower surface of the lower chord.

[0006] Preferably, there are two trusses, and the two trusses are fixedly connected by cross braces.

[0007] Compared with the prior art, the beneficial effects of this utility model are:

[0008] This application features high structural strength and saves on steel reinforcement materials, optimizing usage costs while ensuring usability and greatly increasing its practicality. Attached Figure Description
