Inserting type safety protection railing

An inserting type safety protection railing is formed by stand columns at two ends and a protection screen frame arranged between the adjacent stand columns in an inserting manner, wherein each stand column is formed by oppositely welding web plates of two pieces of channel steel with the same specification, and notches of the channel steel are parallel; a fixed seat is arranged at the lower end of each stand column, through holes are formed in the fixed seat, and the stand column is fastened with the ground through expansion bolts; the protection screen frame is welded by four pieces of square steel, the overall dimension of the square steel is slightly smaller than the inner ring size of the channel steel, the protection screen frame is as high as the stand columns, and a protection screen is fixed in the protection screen frame; and the interval between the adjacent stand columns is matched with the length of the protection screen frame which can be directly inserted into the notches of the stand column channel steel and connected with the stand columns. The inserting type safety protection railing has the benefits as follows: the structure is simple, the operation is flexible, mounting and dismounting are convenient and fast, time and labor are saved, meanwhile, shaping standardization at the construction site can be realized, and the application range can cover all areas of the site.
