[0006] The lower bracket includes three supporting poles, each of which is sleeved with a PVC sleeve; the three supporting poles are fixed to the bottom of the main support frame;

[0007] The adjustable suspension rod is composed of an adjusting screw, an adjusting nut, a transition rod, a hanging plate and a hanging wire; the adjusting screw passes through the threaded holes on the lower positioning plate and the upper positioning plate in sequence and is threadedly connected to the main support frame; the adjusting nut is fixed on the adjusting screw at the upper end of the upper positioning plate, and the hanging plate is fixedly connected to the adjusting screw through the transition rod, and a through hole is provided on the hanging plate for passing the hanging wire.

[0008] Beneficial effects: The utility model has a simple structure and is easy to use; through the combined design of the lower bracket, the main support frame and the adjustable suspension rod, the elevation of the upper steel bars can be adjusted during the concrete pouring process or before the initial setting of the concrete; by burying the PVC sleeve in the concrete, the utility model can be reused.
