The upper end of the connecting vertical rod penetrates through the upper end of the rigid bracket and is fixedly connected with a pressing plate.

[0008] By adopting the above technical solution, the rigid corbel is fixed to the support column through multiple groups of steel bar connectors. After fixing, the floor slab steel bars are placed at the upper end of the rigid corbel. Then, according to the model and diameter of the floor slab steel bars, by sliding the lengthened threaded rod and the sleeve, the connecting vertical rod drives the pressing plate to abut against the upper end of the floor slab steel bars. Then, the lifting limit nut is used to limit the lengthened threaded rod. After completion, the threaded rod penetrates through the pressing plate and is fixed through the threaded hole at the upper end of the rigid corbel.

A lifting limit nut is threadedly connected to the outer end of the lengthened threaded rod above the sleeve. The upper end of the lengthened threaded rod is fixedly connected to the lower end of the reinforcing steel plate.

[0010] By adopting the above technical solution, after the lengthened threaded rod slides out of the sleeve, the slid-out lengthened threaded rod is limited and fixed through the thread of the lifting limit nut and the lengthened threaded rod.

[0011] In a preferred embodiment, multiple groups of steel bar connectors are arranged on one side of the rigid corbel close to the support column. The steel bar connectors include a connecting plate. Threaded cross bars are fixedly connected to the opposite inner sides of the connecting plate. A pressing plate is slidably connected to the outer ends of the threaded cross bars. A second nut is threadedly connected to the outer end of the threaded cross bar away from the pressing plate.

[0012] By adopting the above technical solution, the steel bar connectors can reinforce and fix the rigid corbel, the support column and the floor slab steel bars.

[0013] In a preferred embodiment, multiple groups of threaded holes are formed in the upper end of the rigid corbel. A threaded rod is threadedly connected inside the threaded holes. The threaded rod is slidably connected to the pressing plate. A first nut is threadedly connected to the outer end of the threaded rod above the pressing plate.

[0014] By adopting the above technical solution, the threaded rod penetrates through the pressing plate and is threadedly connected to the first nut, which can reinforce the floor slab steel bars at the lower end of the pressing plate.

[0015] In a preferred embodiment, multiple groups of sliding holes are formed in the upper end of the rigid corbel away from the pressing plate. Multiple groups of steel bar connectors can be penetrated and connected inside the sliding holes.

[0016] By adopting the above technical solution, the steel bar connectors at the upper end of the rigid corbel can reinforce the floor slab steel bars.

[0017] In summary, due to adopting the above technical solution, the beneficial effects of this application are:

[0018] In this application, the rigid corbel is fixed to the support column through multiple groups of steel bar connectors. After fixation, the floor slab steel bars are placed at the upper end of the rigid corbel. Then, by sliding the lengthened threaded rod and the sleeve according to the model and diameter of the floor slab steel bars, the connecting vertical rod drives the pressing plate to abut against the upper end of the floor slab steel bars. Next, the lifting limit nut limits the lengthened threaded rod. After completion, the threaded rod penetrates through the pressing plate and is fixed through the threaded hole at the upper end of the rigid corbel, and then the threaded rod and the pressing plate are fixed by nut one, thereby fixing the floor slab steel bars. Through the cooperation of the above structures, it is possible to prevent damage to the floor slab steel bars during welding and facilitate later recycling. BRIEF DESCRIPTION OF THE DRAWINGS
