Tower crane foundation structure arranged within the scope of the foundation floor and its construction method

Abstract

The invention discloses a tower crane base structure in the range of a base bottom plate, wherein a waterproof cushion layer a is tiled on the upper surface of the tower crane base; a horizontal segment of a waterproof layer is paved on the upper surface of the waterproof cushion layer a; a waterproof cushion layer b is paved on the upper surface of the horizontal segment of the waterproof layer; along the outside surfaces of a stand column and an inclined strut, the waterproof layer is rolled from the horizontal direction to the vertical direction; an L-shaped waterproof protection layer a fits the inner sides of the horizontal segment and a vertical segment of the waterproof layer which protrudes out from the surface of the waterproof cushion layer a to approach to the positions of the stand column and the inclined strut; and a waterproof protection layer b fits the outside surface of the vertical segment of the waterproof layer. The tower crane base structure in the range of the base bottom plate is capable of solving the technical problem that the project quality cannot be ensured due to the unfavorable stress of the base bottom plates as the tower crane bases are arranged below the bottom elevations of the base bottom plates, construction holes are retained on the base bottom plates and the waterproof layers of the bottom plates are connected at the construction holes and solving the technical problem that great inconvenience is brought to the vertical transportation as the construction of the base bottom plates is prior to the mounting of the tower cranes when the tower crane bases are replaced by the base bottom plates.

Description

technical field [0001] The invention relates to a tower crane foundation structure for building construction and a construction method thereof, in particular to a tower crane foundation structure and a construction method thereof arranged within the scope of a foundation bottom plate. Background technique [0002] With the development of the construction industry, the scale of unit projects is getting larger and larger. The vertical transportation equipment in construction generally uses tower cranes. In order to ensure that the tower cranes can cover the construction area to the maximum extent during construction operations, sometimes it is necessary to set the tower crane foundation in the foundation floor of the building. In this case, there are mainly two traditional tower crane foundation methods. : [0003] The first type: the tower crane foundation is set below the bottom elevation of the foundation floor, a construction hole is left in the foundation floor, and the ...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a tower crane foundation structure and its construction method arranged within the scope of the foundation floor, to solve the problem that the tower crane foundation is set below the bottom elevation of the building foundation floor, and when a construction hole is left on the floor, it cannot be closed during the construction process. , the technical problem of unfavorable stress on the foundation floor; solve the technical problem that the stubble area of ​​the waterproof layer on the four sides of the construction hole is relatively large, and the quality of the waterproof project cannot be guaranteed; solve the problem of throwing out the floor around the construction hole due to the limitation of the size of the construction hole The staggered length of the steel bar joints cannot be guaranteed, the steel bar joints are easy to corrode and the technical problems are difficult to connect; solve the technical problem that when the base plate replaces the foundation of the tower crane, the construction of the base plate is preceded by the installation of the tower crane, which brings great inconvenience to the vertical transportation
