Turnover steel latticed column tower crane foundation structure

Abstract

The invention discloses a turnover steel latticed column tower crane foundation structure which comprises a first tower crane base, concrete foundation piles and connecting plates. A first main limb round pipe is arranged in the bottom end of the first tower crane base, and a reinforcement mechanism is arranged on the surface of the outer wall of the first main limb round pipe. The concrete foundation piles are arranged on the surface of the outer wall of the upper portion of the first main limb round pipe and are connected with the first main limb round pipe in a cast manner. A second main limb round pipe is connected to the surface of the top end of the first main limb round pipe. Bolts are arranged between the second main limb round pipe and the first main limb round pipe. The connecting plates are arranged on the surface of the outer wall of the periphery of the second main limb round pipe. A second tower crane base is arranged on the outer side of the first tower crane base. Through study of a latticed column tower crane foundation, a construction method that the structure is simple, operation is simple and convenient, and latticed columns can be repeatedly used is obtained, quality and safety are effectively guaranteed, energy saving and environment protection are achieved, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of tower crane support, in particular to a tower crane foundation structure with a turnable steel lattice column. Background technique [0002] At present, the construction of deep foundation pits in underground space is increasing day by day. In order to increase the basement area, foundation pit support is often extended to the planned red line. If the number of tower cranes is increased, the project cost will be greatly increased; The tower work can only be carried out after the excavation of the earthwork, which will seriously affect the construction progress. [0003] Existing bases for tower cranes cannot reuse the used lattice columns, resulting in more waste and higher costs, and because they cannot adjust the overall radius of the base according to the use requirements of the tower crane , thus limiting the scope of application of the foundation, for this reason, we propose a tower crane foundation...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a tower crane foundation structure with revolvable steel lattice column, to solve the problem that the existing tower crane base proposed in the background technology cannot reuse the lattice column after use, resulting in There is a lot of waste and high cost, and because it cannot adjust the overall radius of the base according to the use requirements of the tower crane, it limits the scope of application of the base
