Construction site stair adjustable type border protective device

Abstract

The invention provides a construction site stair adjustable type border protective device. The construction site stair adjustable type border protective device comprises corner stand columns. Fixing pieces are welded to the bottoms of the corner stand columns and fixed to the ground through expansion bolts. Two square supporting seats are arranged on each corner stand column, and each corner stand column is internally provided with a lead screw and a supporting rod piece which are mutually perpendicular. End blocking pieces are installed at the two ends of each lead screw, and the end of each lead screw is connected with the end of a corresponding connecting rod. A fixing nut is arranged on each lead screw, and the connecting rods are fixed to the lead screws through the fixing nuts. The connecting rods are each of a hollow structure and provided with a plurality of screws. The connecting rods of every two corner stand columns are connected through protective rods which are fixed to the connecting rods through the screws. According to the construction site stair adjustable type border protective device, construction is easy, convenient and fast, recycling for many times is achieved, the adjustable rod pieces can adjust the angles and lengths of the protective rods of different floor heights, and unified standard management is achieved; and meanwhile the time for protective setting up is effectively shortened, and working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the edge protection of the construction site, in particular to an adjustable edge protection device for stairs on the construction site. Background technique [0002] In recent years, the protection of the edges and openings of the construction site has been standardized, the operation standard is fast, and it can be used repeatedly. However, the edge protection of the stairs is still spliced ​​with steel pipe fasteners. This kind of protection is first of all unsightly. Again, when the floor height changes a lot, it is necessary to use steel pipes of various specifications, and sometimes it is necessary to connect butt fasteners. After the protection is completed, it not only depends too much on the workers' operating level, but also requires more labor for on-site management. And it can't be used on a turnover basis, which causes a waste of labor and labor time, and increases the cost of the measure. Contents of the inventi...

Moreover, it cannot be used on a turnover basis, causing a waste of labor and labor time, and increasing the cost of measures.
