Description

Operation platform for prefabricated staircase

Technical Field

The utility model belongs to the technical field of operation platform, especially, relate to an operation platform that prefabricated staircase used.

Background

In recent years, with the rapid development of assembly type buildings in China, the application of prefabricated assembly type stairs is more and more common. In the cast-in-place concrete structure of the prefabricated staircase, the rest platform of the staircase is generally cast in-place concrete, and the prefabricated staircase needs to be installed after the concrete of the rest platform of the staircase reaches a certain strength. The installation lag of the prefabricated staircase causes the workers to have no operating space for the construction operation of the previous layer. The prefabricated assembled stairway is affected by factors such as field supply, construction arrangement and the like, and can not be installed in place in time, so that the construction height of the stairway is too high. If no reliable hole opening sealing measure or anti-falling measure exists, safety accidents are easy to happen.

The traditional solution is to set up or place temporary scaffold construction chute on the next floor of prefabricated staircase, and the worker carries out construction operation on the temporary construction chute. And after the concrete pouring of the construction layer is finished, the construction chute is dismantled, or the construction chute is lifted away from the staircase by using a tower crane. When the prefabricated staircase on the previous layer is installed, a construction chute needs to be erected on the staircase again, or the prefabricated staircase is hung on the staircase again by a tower crane, and then the construction operation of the previous layer is carried out. When the number of the lagging layers of the prefabricated stair sections is too large, the scaffold construction inclined channel is limited by the height and the weight of the scaffold construction inclined channel, the construction operation with too high height is difficult to support, I-shaped steel needs to be overhung, and then the construction inclined channel is erected and placed on the I-shaped steel.

If the method is adopted, scaffolds are required to be erected during the construction of each floor of the stairs, and the repeated installation and removal work causes great waste of labor, materials and machines. In addition, the stairwell space is narrow and small, and the scaffold is built and is spent time and power, influences the project progress. Meanwhile, the stability of the floor scaffold is poor, and great safety risk exists in construction.
