Removable telescopic edge protection system for construction

Abstract

An aspect relates to a removable telescopic edge protection system for construction, orifices arranged from top to bottom are formed in left and right end walls of an inner tube, metal materials originally existing at corresponding positions of the orifices are bent to an inner side of the inner tube, and the metal sheets on a left side are fixedly connected in pairs with the metal sheet on a right side, such that structural firmness of the inner tube can be enhanced, structural stability of the inner tube can be effectively ensured without greatly increasing a wall thickness of the inner tube, an increase of an overall weight of a telescopic edge protection post caused by the increase of the wall thickness of the inner tube is favorably avoided, carrying and using convenience of the telescopic edge protection post can be effectively improved.
