Description

Technical Field

[0001] The present application relates to the field of construction, and in particular to a tower crane foundation structure and a basement structure embedded in a basement top plate. Background Art

[0002] At present, tower cranes have become important equipment for vertical transportation of materials in the construction field, and play an important role in improving the efficiency of construction. Usually the tower crane foundation is set on the basement floor, so holes need to be left in the basement floor slabs and the basement roof for the tower crane to pass through, and the holes can only be closed after the tower crane is dismantled.

[0003] However, since the construction period of construction projects is generally long, the spaces on each floor of the basement within the range of the tower crane cannot carry out relevant process operations in a timely manner due to the existence of the tower crane, which has an adverse effect on the arrangement of the construction process. In addition, since the holes of the tower crane have not been sealed for a long time, the water flow and rainwater on the top of the basement flow directly into the basement through the holes, causing the basement to be in a humid state for a long time, which can easily cause the metal equipment and facilities in the basement to rust and be damaged. Utility Model Content

[0004] The purpose of this application is to provide a tower crane foundation structure and a basement structure embedded in the basement roof, which ensures the integrity of the entire basement construction process, prevents external water from entering the room and ensures a dry indoor environment.
