Fabricated steel structure tower crane foundation bearing platform

Abstract

The invention discloses a fabricated steel structure tower crane foundation bearing platform. The fabricated steel structure tower crane foundation bearing platform comprises a plurality of sub-steelstructure bearing platforms, the sub-steel structure bearing platforms are connected through arc-shaped H-shaped composite steel members, a plurality of adjustable-size H-shaped steel members, cross-shaped H-shaped steel members and U-shaped buckles; the sub-steel structure bearing platforms comprise lattice columns of a lower foundation, reinforced cages, concrete and round steel pipes; the reinforced cages are arranged in the round steel pipes, the lattice columns of the lower foundation are arranged in the reinforced cages, and the concrete is poured between the round steel pipes and the lattice columns; and the outer sides of the round steel pipes are fixedly connected with the arc-shaped H-shaped composite steel members, the arc-shaped H-shaped composite steel members are connected with the adjustable-size H-shaped steel members through the U-shaped buckles, the adjustable-size H-shaped steel members are connected with one another through the U-shaped buckles, and the adjustable-size H-shaped steel members are connected with the cross-shaped H-shaped steel members through the U-shaped buckles. The force is reliable, and the installation and disassembly are convenient. The problems of long maintenance time for construction of a cast-in-situ concrete tower crane foundation bearing platform, waste of concrete materials and environmental protection are solved.

Description

technical field [0001] The invention relates to the field of building structures, in particular to an assembled steel structure tower crane foundation cap. Background technique [0002] Tower crane is an indispensable main construction machinery in the mechanization and assembly of modern industry and civil construction. With the continuous development of the construction industry, the number of multi-storey and high-rise buildings in major and medium-sized cities continues to increase, and tower cranes have become the main artery for vertical and horizontal transportation of multi-storey and high-rise building construction. The application of tower cranes plays an important role in speeding up the construction progress, shortening the construction period and reducing the project cost. In the use of tower cranes, the foundation is a crucial part. When the bearing capacity of the ground cannot meet the requirements, pile foundations are often used. Most of the foundations of...
