The loose-branch loose-dismantling formwork is the most traditional construction process, the specifications and the quantity of the formworks are listed according to the construction drawing directly according to the size, and the formworks are assembled on site. The three-hinge cylinder mould is characterized in that a positive and negative buckling screw rod fixed on a vertical steel enclosing frame of the mould plate interacts with a nut, a screw rod of a bolt is rotated, so that three-hinge angle moulds at four corners in the three-hinge cylinder mould are rotated along with the screw rod to enable the mould plate to integrally expand or contract along the horizontal direction, and the mould supporting and the mould removing of the mould plate are realized. The eight-hinge cylinder die consists of eight hinges and eight large die plates, the die plates are connected by the hinges, a vertical shaft in the middle of four sides is provided with a steel support, 2-3 steel supports can be arranged from top to bottom according to the layer height, the middle of each steel support is connected by a positive and negative rotating double-headed screw, and two ends of each steel support are connected with the vertical shaft of the die plate by bolts; when the formwork is dismantled, a worker twists the steel support screw rod to contract inwards to drive the vertical shaft to retract together, the formwork is separated from the surface of concrete, and the defects are as follows:

1. the loose-branch loose-dismantling formwork is not only time-consuming and expensive in the construction of the traditional formwork system, but also has many disadvantages: the mold needs to be installed by multiple persons in a matching way, so that large errors exist, the process is troublesome to disassemble and assemble, and the mold is slow and difficult to demold; and has significant potential safety hazard.

2. The three-hinge cylinder die is labor-consuming and time-consuming; the hinged part is not easy to fix, the rigidity is not enough, and the quality of the hinged part is easy to cause problems when the mould is folded; the angle mould is not tightly connected with the large formwork, and the concrete quality can not be ensured.

3. The reinforced part of the middle screw rod of the eight-hinge cylinder mould body is easily blocked by the leaked slurry; the hinge part has insufficient rigidity, is easy to expand a mould, leaks slurry and can not ensure the quality of concrete.

Therefore, there is a need to provide a new retractable form for elevator shafts to solve the above technical problems.
