Retractable unit horizontal hard protection

Abstract

A retractable unit horizontal hard protection comprises a protective underframe and a protective railing. The outer side edge of the protective underframe is connected with the protective railing perpendicularly. The protective underframe is formed by connecting two main beams and a secondary beam. The protective underframe is paved with a bottom plate. The bottom plate is provided with a transverse rib. The inner end of the main beam is hinged with the outer side of the bottom of an inter-layer steel supporting bracket connected between two layers of structural floor slabs by a rotating shaft. The outer side of the gravity center for the two main beams is fixed with two hanging rings respectively. A wire cable is connected between the hanging ring and the inner side at the top of the inter-layer steel supporting bracket. The invention can resolve the safety demand and the construction demand of simultaneous construction at upper and lower different working areas in a same vertical direction, thereby reducing the limb working time for workers, lowering the risk of falling matters from high altitude, and simultaneously providing convenience for the inverse transportation of the material tool at the lower section by retracting the protective unit. The horizontal protective system is convenient to process and is convenient and fast to mount and demount; and the horizontal protective system is convenient to open and can be used in recycle manner with low cost.

Description

technical field [0001] The invention relates to a construction protection of an outer facade in the construction of a super high-rise building and a construction method using the protection. Background technique [0002] At present, when there is a vertical cross construction in the construction of super high-rise buildings, steel pipes are often used to erect horizontal hard protection, and the bottom plate is laid on top, which is erected as a whole. After the erection is completed, the transportation of the lower materials and machinery is greatly restricted, and transportation is very difficult; at the same time, because the parts are assembled on the facade of the project, it takes a long construction period, the labor intensity of the workers is high, the operation risk is high, and there is a high-altitude fall. The chances are also higher. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a re...
