Technical Field

The application relates to the field of building construction, in particular to construction safety protection equipment.

Background

The elevator shaft is a shaft for installing an elevator, the size of the shaft is determined according to elevator type selection, an elevator track and a counterweight track are installed on the wall of the shaft, an elevator door is installed at a reserved door opening, and the position of the elevator shaft is required to be reserved in house building construction. Due to the structural characteristics of the elevator shaft, the elevator shaft becomes an important critical falling risk management and control area in the building during construction.

In the current construction, the protection of the elevator shaft mostly adopts the measures of reserving steel bars inside, paving templates and steel plates above the steel bars or additionally installing protection nets and the like to realize the hole isolation between each floor. Meanwhile, the elevator shaft door opening is provided with a guard rail or a closed door in a fake manner. However, the mode of reserving the reinforcing steel bars also needs to be used for cutting the reinforcing steel bars in later construction, which clearly increases the construction steps and the additional construction risks. For the steel bar heads which are not cut in place, the installation and construction of the later-stage elevator can be influenced.

In addition, the protection mode of the reserved steel bars is not ideal for the adaptation degree of the frontal elevator shafts with different sizes. The concrete is that the strength of the plate surface is paved above the reserved steel bars, and the strength is inconsistent after the size of the elevator shaft is changed.
