Description
Technical Field
The utility model relates to a construction technical field, concretely relates to dismouting is convenient, can repeat turnover use, anti-seismic performance is good, safe and reliable's assembly weighs formula tower crane foundation structure.
Background
The tower crane is the most common hoisting equipment on the building site, also called tower crane, which is lengthened section by section (called standard section for short) and is mainly used for vertical and horizontal conveying of materials and installation of building components in the building construction due to large operation space, and is also commonly used for pouring large-volume concrete in hydraulic engineering. The tower crane is hung by the hanging arm which is hung out, so that a very large dumping moment is generated, and the requirement on the bearing capacity of a bearing foundation is high, so that the foundation structure of the tower crane is a necessary condition for keeping the safe operation of the tower crane.
The tower crane foundation structure is generally formed by pouring concrete into a base, and the length, height, width and reinforcing bars of the base need to meet the requirements of the tower crane on overturning stability, foundation bearing capacity and base crack resistance. However, for installing a tower crane in an environment where a basement has been constructed and put into commercial use, a common method is a cast-in-place pile, a steel pipe pile + a lattice steel column, a steel pipe column + a concrete bearing platform or a profile steel platform, and although the above-mentioned various construction methods can meet the requirements of a tower crane foundation structure, due to the complex installation, high cost and poor seismic performance of a combined foundation, the cast-in-place pile or the steel pipe pile cannot be constructed when a multi-layer basement is encountered and a basement bottom plate is finished, the pulling resistance, torsion resistance and bearing capacity of the foundation cannot be guaranteed, and a part of space is occupied, so that the use function of the basement which is put into use is affected. Therefore, in the prior art, an integral reinforced concrete beam is used as a support of the tower crane, and the support column at the bottom of the reinforced concrete beam is supported on the frame column structure of the basement, so that although the construction time is shortened and the support column can be repeatedly used, the rigid reinforced concrete beam structure is poor in anti-seismic performance and is directly supported on the frame column structure of the basement through the support column, so that the connection reliability is poor, the anti-sliding capacity is weak, and the anti-seismic performance is further reduced. In addition, in the prior art, a prefabricated assembled reinforced concrete structure is adopted as a tower crane foundation, so that the problems of incapability of reuse, poor anti-seismic performance and high construction difficulty are solved, but the split assembled reinforced concrete structure is connected with a basement frame column structure through an anti-sliding shaft, so that the reliability is poor, the disassembly and assembly are difficult, the toughness of the reinforced concrete structure is poor, the reinforced concrete structure is easy to damage in the use and transportation process, and the use cost is high. Therefore, in order to solve the problems of the reinforced concrete beam in the prior art, the concrete pressing block is arranged on the longitudinal beam in a pressing mode, so that the longitudinal beam and the cross beam are pressed and fixed tightly to form a tower crane foundation, the tower crane foundation is arranged on a top plate of a basement through a support at the bottom, and although the tower crane foundation is simple to disassemble and assemble, low in cost and not easy to damage, a stacked structure of the tower crane foundation is poor in connection reliability, weak in anti-sliding capacity and poor in overall anti-seismic performance. Therefore, it is necessary to develop an assembled tower crane foundation structure capable of solving the above problems.
