Description

Technical Field

[0003] The related patent with the publication number CN209482594U provides a truss bar, which includes an upper chord bar, web bars and two lower chord bars. The upper chord bar and the two lower chord bars are arranged in parallel and in an isosceles triangle form. The two lower chord bars are respectively located on both sides below the upper chord bar, and both the two lower chord bars and the upper chord bar are connected by web bars, and the web bars are arranged as corrugated bars. When assembling the truss bar, the steel bars at each place are placed in appropriate positions, and a complete truss bar can be formed by welding the upper chord bar and the lower chord bars with the web bars.

[0004] Regarding the above-mentioned related patent, the inventor found that during the process of pouring the truss bar into a concrete rib to make a composite slab, the truss bar needs to be placed upside down in the concrete pouring container. Since there is only one upper chord bar, the stability of the truss bar after being turned upside down is poor. Therefore, it is necessary to position the truss bar through a positioning tooling before concrete pouring. However, due to the large volume and weight of the positioning tooling, it is inconvenient to carry, so the truss bar needs to be concretely poured at a specific site. When the construction site is not convenient for installing the positioning tooling, the working efficiency and the forming quality will be reduced, so it needs to be improved.

[0049] Referring to Figure 3 and Figure 4 , a rotary torsion spring 331 is sleeved on the outer wall of the rotating rod 33. The rotary torsion spring 331 and the support rib 31 correspond to each other one by one. The two end force arms of the rotary torsion spring 331 are respectively connected to the outer wall of the corresponding rotating rod 33 by gluing, so as to be able to drive the two support ribs 31 to rotate towards each other, so that the support ribs 31 can better abut against the upper chord rib 11; the abutting rib 32 is integrally formed at one end of the corresponding support rib 31 facing away from the other support rib 31.
