[0017] Furthermore, the screw size is M24×60.

[0018] Furthermore, the size of the steel bar connector is M24×70.

[0019] Beneficial effects

[0020] This invention reduces the need for steel pipes, formwork, and wooden planks used for later concrete support outer formwork. The colored strips isolate the concrete from the steel support, reducing contamination of the steel support and facilitating its subsequent removal and recycling. This reduces safety hazards and construction difficulties in later foundation pit construction, avoiding resource waste and improving the safety of foundation pit enclosures while achieving technical benefits and saving construction costs.
