Description

A construction elevator foundation conversion steel cap

technical field

The utility model relates to the field of high-rise building construction, in particular to a construction elevator foundation conversion steel bearing platform.

Background technique

Construction elevators are essential vertical transportation equipment for high-rise construction. During the construction process, construction elevators often occupy the official elevator shaft, which affects the masonry inserted in advance at the official elevator shaft, as well as the installation and hardcover construction, and affects the overall construction progress. If the construction elevator is removed, the construction of the upper structure will be affected, and the configuration of the standard section of the elevator will not reach the required construction height, which will not meet the construction requirements.

In addition, in super high-rise construction, the construction progress of the core tube is generally ahead of the outer frame structure, which requires several construction elevators to be arranged in the core tube to ensure vertical transportation. The location of the construction elevators is to avoid affecting the construction of the inner tube floor. Often occupy the shaft of the formal elevator. Due to the long construction period of super high-rise structures, formal elevators are often inserted in advance during the construction period of the structure. At this time, the construction elevator is still occupying the official elevator shaft, and the construction elevator cannot be removed, and the official elevator cannot be installed in advance, which affects the construction progress of the entire project. .

At present, one way to solve the above problems is to reset an elevator foundation on the high floor, install another elevator, and remove the previous construction elevator, but this method needs to stay for a long time to install a new elevator, which not only affects the construction period, but also Increased construction costs, resulting in unnecessary waste.
