Construction method combining tower crane foundation and building basement floor

Abstract

The invention discloses a construction method combining a tower crane foundation and a building basement floor, and belongs to a building construction method. The method comprises the steps that an earthwork slot of a tower crane is excavated downwards in the building basement floor, and brick forming dies are built in the earthwork slot along the inner walls of the earthwork slot; waterproof materials are laid in the earthwork slot along the brick forming dies, and the waterproof materials are extended from the earthwork slot onto an adjacent building basement floor. Due to the fact that the construction technique combining the tower crane foundation and the building basement floor is adopted, potential safety hazards left in the detaching process of the tower crane are effectively eliminated; because the tower crane foundation is flush with the basement floor, the problem of long-term ponding of the installing position of the tower crane is avoided, and the working procedures of demounting and mounting the tower crane are simplified. Meanwhile, the construction method combining the tower crane foundation and the building basement floor has the advantages that construction procedures are simple, suitable for being applied to the construction process of the tower crane of various mid-rise buildings and high-rise buildings and easy to popularize.

Description

technical field [0001] The invention relates to a building construction method, more specifically, the invention mainly relates to a construction method in which a tower crane foundation is combined with a basement floor of a building. Background technique [0002] In recent years, with the rapid development of modern buildings, there are more and more buildings with high-rise buildings, super high-rise buildings, and main buildings with large basements. within the basement floor. The traditional construction method is to set the top of the tower crane foundation below the basement floor. After the concrete pouring of the basement floor, the tower crane foundation is surrounded by a sunken pit. During the construction process, it is easy to cause long-term water accumulation in the pit, and After the tower crane is dismantled, the reserved steel bars on the basement floor must be bent before waterproofing can be done. During the bending process, quality problems are likely ...

AI Technical Summary

Problems solved by technology

[0003] One of the objectives of the present invention is to address the above-mentioned deficiencies and provide a construction method combining the foundation of the tower crane with the floor of the basement of the building, in order to solve the problem of narrow operating space and difficult working procedures when tower cranes are installed on the floor of the basement in the prior art. It is cumbersome, and the operation of bending steel bars after the removal of the tower crane foundation is likely to leave technical problems such as safety hazards in the later construction
