Description

Technical Field

[0001] The utility model relates to the technical field of building main body construction, in particular to an elevator shaft protection device, which is synchronously constructed with a main structure, has a simple construction sequence and high construction efficiency. Background Art

[0002] At present, scaffolding is generally set up in elevator shafts for main structure construction. Horizontal protection in the shaft is generally set up every 2 floors and no more than 10m, and safety nets are set up at other floors. Hard isolation is usually laid with templates (usually wooden templates, constructed by carpenters), and soft isolation is first set up with horizontal steel pipes in the gap between the floor and the scaffolding, and then the safety net is laid. This construction method has many processes and involves the coordinated operation of multiple types of work (the scaffolding is completed by the scaffolding workers, and its construction is synchronized with the main structure construction, while the hard isolation requires the cooperation of carpenters). This not only causes the horizontal protection of the elevator shaft to lag in place, which brings safety hazards to the on-site construction, but also greatly affects the efficiency of on-site construction.

[0003] Therefore, it is of great practical significance to develop an elevator shaft protection device that is constructed synchronously with the main structure, has a simple construction sequence and high construction efficiency. Utility Model Content

[0008] The vertical pole is fixedly connected to the wall corner of the elevator shaft through a wall connecting piece.

[0009] The elevator shaft protection device of the utility model has a reasonable structural design.

Scaffolding boards are laid on the cantilevered horizontal short rods, which can achieve maximum coverage and protection of the shaft. The horizontal protection and the shaft scaffolding are constructed simultaneously. The construction sequence is relatively simple, and there is no need for the coordination of multiple types of work. The overall construction efficiency is high and the application prospect is good.

The horizontal floor frame is fixedly connected to the vertical poles 3 and the multi-layer horizontal floor frames are connected into one by the vertically arranged vertical poles 3. The horizontal floor frame is surrounded by multiple horizontal rods 2 connected end to end. The horizontal floor frame is flush with its corresponding floor plate. A scaffolding board 5 is laid on the horizontal floor frame. A cantilevered horizontal short rod 4 fixedly connected to the horizontal floor frame or the vertical pole is also provided between the horizontal floor frame and the floor plate. The two opposite cantilevered horizontal short rods 4 are also laid with scaffolding boards 5.
