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.

The inner of above-mentioned main beam is by turning cylinder and to be connected the bottom outside of the interlayer steel bracing frame between the double-layer structure floor hinged, the center of gravity of the two main beams outside is fixed with two suspension ring respectively, is connected wire rope between the inside top of above-mentioned suspension ring and interlayer steel bracing frame.
Above-mentioned interlayer steel bracing frame is to be formed by fixedly connecting by four steel pipe columns, stull, bottom shaped steel and top shaped steel, and the outer end of bottom shaped steel is fixed with and is used to connect the axle bed that protects underframe, and the inboard of top shaped steel is fixed with the bolt seat that is used to connect wire rope.
The cross rib of above-mentioned protection underframe can be reinforcing bar or shaped steel.
Above-mentioned main beam and time crossbeam are shaped steel.
The job practices of this ethnic group retractable unit horizontal hard protection: it is characterized in that:
Step 1, the processing retractable unit horizontal hard protection, become the protection underframe with main beam, inferior crossbeam and the integral installation of cross rib burst, and on the protection underframe, lay base plate, the outer side edges of protection underframe is connected with guard rail is vertical, with turning cylinder with main beam and to be connected the bottom outside of the interlayer steel bracing frame between the double-layer structure floor hinged, and on main beam fixing suspension ring, between the inside top of suspension ring and interlayer steel bracing frame, be connected wire rope;
Step 3 when needs vertically transport material up and down, after by turning cylinder above-mentioned protective unit being erected, is fixed on the front end of wire rope on the interlayer steel bracing frame, and end is fixed on two suspension ring.
Beneficial effect of the present invention is as follows:
The present invention adopts shaped steel, base plate and reinforcing bar to manufacture the hard protection unit, and turning cylinder is set on main joist, protective unit can be erected when needing.By using retractable unit horizontal hard protection, can solve demand for security and construction demand that same vertical different work district up and down constructs simultaneously, reduce the workman and face the limit activity duration, reduce the risk of falling object from high altitude, simultaneously by the protective unit folding and unfolding, have bad luck for compresses lower section material facility and to facilitate.This horizontal protective system is convenient to processing, peace and is torn open convenient, fastly, and it is convenient to open, and can have enough to meet the need use, and cost is lower.
Job practices of the present invention can be assembled into different units, the burst integral installation in that the bottom construction is not had to use the simple member of specification, negligible amounts under the prerequisite of influence.When needing material vertically to have bad luck in the bottom, local unit upset can be erected,, improve the safety of workman's operation so that construction is simplified in having bad luck of material, facility.
