Telescopic bracket device capable of achieving circulation and using method of telescopic bracket device

Abstract

The invention belongs to the technical field of super high-rise building construction, and discloses a telescopic bracket device capable of achieving circulation and a using method of the telescopic bracket device. The telescopic bracket device comprises an external connection sleeve beam, a telescopic joint, a telescopic mechanism and ejection adjusting mechanisms; the external connection sleeve beam is fixedly installed at the end of a supporting beam of a tower crane, one end of the telescopic joint is arranged in the external connection sleeve beam in a manner of being capable of sliding in the axial direction, and the other end of the telescopic joint extends out of the external connection sleeve beam; the other end of the telescopic joint is detachably installed on a wall of a core barrel, and the telescopic mechanism is arranged in the external connection sleeve beam and located between the external connection sleeve beam and one end of the telescopic joint; the multiple ejection adjusting mechanisms are evenly arranged between the external connection sleeve beam and the telescopic joint, one end of each ejection adjusting mechanism is fixedly installed on the external connection sleeve beam, and the other end of each ejection adjusting mechanism penetrates the external connection sleeve beam to be in contact with the outer surface of the telescopic joint. By means of the telescopic bracket device, loads of the supporting beam of heavy equipment like the tower crane can be effectively transferred, and are transferred along with the supporting beam, and circulation using is achieved.

Description

technical field [0001] The invention belongs to the technical field of super high-rise building construction, and in particular relates to a turnable telescopic corbel device and a use method thereof. Background technique [0002] In the construction of super high-rise buildings, heavy-duty construction equipment represented by tower cranes used for core tube construction requires a large number of measures such as steel embedded parts and steel corbels, which cannot be used in turnaround, resulting in high costs, and the construction of these measures The process is complex, involving factory production of components, on-site high-altitude welding, and cutting off when used up, which requires a lot of labor and has high construction risks. Therefore, it is very necessary to design a turnable heavy equipment support beam support device. Contents of the invention [0003] The purpose of the present invention is to provide a turnable telescopic corbel device and its use met...
