Semiautomatic self-climbing hoisting mechanism of light steel structure under closed structure

Abstract

The invention relates to a semiautomatic self-climbing hoisting mechanism of a light steel structure under a closed structure. The semiautomatic self-climbing hoisting mechanism comprises a main load-bearing truss body and a hydraulic jacking mechanism, which are arranged in a core drum, wherein a climbing guide rail which extends along the vertical direction is also arranged inside the core drum, the main load-bearing truss body is matched with the climbing guide rail, and the hydraulic jacking mechanism can drive the main load-bearing truss body to move along the climbing guide rail; and a material to be hoisted is driven to transfer between the interior and the exterior of the core drum by virtue of a material platform (particularly an article to be hoisted from the exterior of the core drum is transported into the core drum). The construction efficiency is improved, the interval of the construction period is shortened, the construction period is greatly shortened, the construction cost is greatly saved, the construction safety risk is effectively reduced, and good social benefit, environmental benefit and economic benefit can be achieved.

Description

technical field [0001] The invention belongs to the field of construction engineering, and relates to a steel structure construction hoisting mechanism, in particular to a "self-climbing, semi-automatic" hoisting mechanism capable of performing steel structure hoisting operations in a closed structure. Background technique [0002] At present, most of the (super) high-rise buildings in my country adopt the frame-core tube structure system (reinforced concrete core tube or steel concrete core tube), in order to improve the construction efficiency of the core tube concrete structure, reduce the loss and loss of wood caused by artificial formwork Advocating green construction, most of the concrete construction of the core tube adopts large-scale steel formwork + climbing formwork or top formwork technology. It makes it impossible to use large machinery such as tower cranes for the construction of the inner plane structure of the core tube, and can only manually reload materials, ...
