Telescopic horizontal protection device acting on creeping formwork construction

According to the utility model, the problem of lack of horizontal protection during formwork climbing construction of workers on a working plane is solved, and the possibility of high-altitude falling accidents is reduced; compared with a conventional method of hanging a horizontal protective net, the steel structure is high in stability, and safety risks are reduced; and the expansion and contraction are convenient, repeated disassembly is not needed, repeated use is realized, and the operation is simple and convenient, so that the construction cost is saved, the construction time is shortened, and the construction efficiency is improved. A telescopic horizontal protection device acting on creeping formwork construction comprises an operation platform and a handrail arranged on one side of the operation platform. The handrail comprises a plurality of longitudinal rods and a transverse rod; a plurality of conical through holes for the longitudinal rods to penetrate through are formed in the side wall of the o
