The construction method of this kind of retractable unit type horizontal hard protection: it is characterized in that:

Step 1, process the retractable unit horizontal hard protection, install the main beam, the secondary beam and the ribs as a whole to form a protective chassis, and lay a bottom plate on the protective chassis, and connect the outer edge of the protective chassis with the protective chassis. The railings are vertically connected, and the main beam is hinged to the bottom outer side of the interstory steel support frame connected between the two-story structural floors with a rotating shaft, and the suspension ring is fixed on the main beam, and the top inner side of the suspension ring and the interstory steel support frame is connected. between connecting wire rope;

Step 2, set the main beam of the retractable unit type horizontal hard protection parallel to the structural floor;

Step 3, when the material needs to be transported vertically up and down, after the above-mentioned protective unit is erected through the rotating shaft, the front end of the steel wire rope is fixed on the interlayer steel support frame, and the end is fixed on the two suspension rings.

The beneficial effects of the present invention are as follows:

The present invention adopts section steel, base plate and steel bars to process and manufacture hard protection unit, and sets rotating shaft on the main keel, and the protection unit can be erected when necessary. By using retractable unit-type horizontal hard protection, it can solve the safety and construction needs of simultaneous construction in different work areas in the same vertical direction, reduce the time for workers to work on the sidelines, and reduce the risk of falling objects. At the same time, the protection unit can be retracted, It provides convenience for the reverse transportation of materials and tools in the lower section. This horizontal protection system is easy to process, convenient and quick to install and disassemble, easy to open, can be used repeatedly, and has low cost.

The construction method adopted in the present invention can be assembled into different units by using simple components with small specifications and quantities without affecting the construction of the lower part, and install them as a whole in pieces. When materials need to be transported vertically in the lower part, partial units can be turned upside down to facilitate the transport of materials and machines, simplify construction and improve the safety of workers’ operations.
