[0002] In the construction of high-rise buildings, the elevator shaft construction must be carried out simultaneously with the main structure construction phase. The elevator shaft is a dedicated space for installing elevators. The elevator tracks and counterweight tracks are installed in the shaft, and the reserved door openings are used to install elevator doors. Before pouring the elevator shaft, the inner and outer molds must be supported to form a square cylinder. The cavity formed between the inner and outer molds is used to pour concrete. The formwork structure of this square cylinder structure has the problem of being difficult to fix at the corners, which makes it easy for material to leak during the pouring process. In addition, during the construction of the elevator shaft formwork, an operating frame platform needs to be set up, which is erected upwards as the number of floors increases.
