This creation is related to formwork used in construction, especially a telescopic formwork group.

Formwork is a kind of construction equipment. In the process of building walls, steel bars are usually erected first, and then the shapes of beams, columns, walls and other architectural structures are surrounded by formwork, and then fixed. Finally, concrete is poured into the formwork In the surrounding space, after the concrete is solidified, the formwork can be removed to complete the shaping of the building structure.

Among them, in the process of constructing a surrounding wall with a rectangular space inside, such as an elevator shaft and a room, the existing method is to combine multiple formworks to form an inner and an outer formwork. The outer formwork and the inner formwork are both rectangular. The area enclosed by the outer formwork is larger than the area enclosed by the inner formwork, and surrounds the inner formwork. A pre-set ring-shaped steel bar structure is surrounded between the outer formwork and the inner formwork. After fixing, concrete is poured between the outer formwork and the inner formwork to form the desired wraparound wall.
