Description

TECHNICAL FIELD

[0001] The present application relates to the field of construction engineering, and in particular to a tower crane wall-attached quick-mounting cross inner support rod structure. BACKGROUND

[0002] When a tower crane is installed and used in a construction site, as the building height increases, the tower crane often needs to exceed the independent height designed by the manufacturer, at which point the tower crane needs to be installed with a wall-attached device to continue jacking within the design-allowed range. With the increasing perfection of national standards and industry standards, and the increasingly fierce market competition, there are higher and higher requirements for the structural safety design and humanization design of tower cranes. Manufacturers generally design a wall-attached system for their own tower crane products, which has a standard section inner support structure inside the system to improve the structural safety and stability of the tower body node.

[0003] There are mainly two design forms of wall-attached devices with inner support structures on the market at present: 1. The wall-attached device with a cross-intersection inner support structure places the structural member at a specified position of the tower body and fixes it using an adjusting screw to tighten. 2. The wall-attached device with a clamp-type inner support structure has four clamp claws fixed to the wall-attached frame with a pin shaft, and the force is transmitted to the wall-attached frame after the tower body is tightened using an adjusting screw or a wedge.
