technical field

The utility model relates to a safety protection device for construction operations, in particular to an external cantilever steel scaffold with horizontal protection function which combines an external cantilever scaffold and horizontal protection into one.

Background technique

Preventing falling objects from height is one of the key points of construction site safety management, especially in the construction stage of the main structure of high-rise buildings. There is no horizontal protection on the periphery, and major safety accidents such as object strikes will occur.

The peripheral horizontal protection of the traditional high-rise building structure is to use φ48.3mm×3.5mm steel pipes, fasteners, steel wire ropes and large eye nets to assemble a 3.0m wide horizontal cantilever protective net around the structure of the removed external scaffolding. Steel pipes and fasteners are used as the cantilevered skeleton, and the large eye net is bound on the cantilevered skeleton as a horizontal protective net. In the reserved hole on the top plate of the protective layer. This kind of traditional horizontal protection mainly intercepts falling objects with large eye nets. Generally, a horizontal pocket net is set every two to three floors. It is a kind of horizontal soft protection, which is easily penetrated by slightly heavier and larger falling objects. A high-altitude object strike occurred, causing a safety accident. In addition, because it needs to be installed on the periphery of multiple floors, the construction is cumbersome, the construction volume is large, and it will affect the appearance of the structure under construction.

In order to prevent the construction personnel or the construction tools from falling from the bottom of the protective railing due to accidental contact by the construction personnel, the bottom of the protective railing is vertically fixed with a foot guard.

In order to further enhance the load-bearing capacity of the outer horizontal hard protective layer and save material costs, the horizontal hard protective layer includes multi-layer boards and scaffold boards from bottom to top, and the thickness of the multi-layer boards is 11-13 mm (for example, it can be 12mm), the thickness of the scaffold board is 49~51mm (for example, 50mm), and the junction of the scaffold board and the cantilever steel is bound with iron wire.

Further, the cantilevered scaffold is fixedly connected to the roof of the structural layer through connecting rods and wall parts, which can improve the stability and safety performance of the cantilevered scaffold.

Beneficial effects: the utility model directly utilizes the existing cantilevered steel at the bottom of the external scaffolding to combine the horizontal protection and the external scaffolding into one to form a horizontal hard protection layer, which avoids the breakdown of the horizontal protection when heavy objects fall and improves the level The safety of protection; and only the horizontal hard protective layer is set on the cantilevered steel, which saves the construction of multi-layer cantilevered steel pipe skeleton, the binding of horizontal nets and the cable-stayed wire rope, which greatly improves the convenience of construction; At the same time, various parts in the utility model, such as cantilevered steel, protective railings, etc., are easy to disassemble and use, can be used flexibly and can be used in high-efficiency turnover, saving economic costs; the protective railings in the utility model can prevent falling objects from falling on horizontal hard The guard bounces off and falls off the outer edge of the hard guard.
