Tower crane wall attached member bar device

Abstract

The invention discloses a tower crane wall attached member bar device. A connecting lug plate is fixed on a steel pipe cylinder; a wall attached member bar is fixed on the connecting lug plate by a connecting plate, so that the wall attached member bar is firmly attached to the steel pipe cylinder, and can be stabilized for a long time so as to guarantee the stability and the safety of a tower crane and the wall attached member bar in the using process of the tower crane; the processing and manufacturing, field installation and adjustment difficulty of the wall attached member bar can be reduced, and the wall attached member bar is more convenient to install and detach, and can be utilized repeatedly after being detached; the construction cost is reduced greatly; the safety hazard possibly caused by the changing of the stress direction and size of attached objects in the construction process of the tower crane is solved; meanwhile, the structural influence is relatively tiny; the precision requirement for subsequent construction is met; meanwhile, the stability in the using process is ensured.

Description

technical field [0001] The invention relates to the technical field of super high-rise building steel structure construction, and relates to a tower crane attachment wall rod device. Background technique [0002] At present, super high-rise buildings are springing up like mushrooms after a spring rain in China. Tower cranes used in construction are usually roughly divided into three types: external attachment, internal climbing and external hanging. For the attached tower crane, how to solve the attachment of the tower crane itself and the building itself is the key factor of the whole project. Among them, it is necessary to take into account the stability of the structure itself after the equipment is attached, and also take into account the differences in the attachment conditions of different buildings. [0003] For the commonly used external tower cranes, the outer structure of high-rise buildings is generally a concrete rigid column. It is generally used to preset embe...

Problems solved by technology

[0004] However, the connecting plate of the hoop on the steel pipe cylinder can withstand tensile force better than the pressure bearing capacity, and the installation components of high-rise steel structures generally have a large single weight. Converting from tension to pressure, such a long-term continuous conversion will affect the connection between the hoop and the steel pipe cylinder, which is not conducive to stability
