CN203867210U - Protective connection device for floor adjacent edges - Google Patents

Abstract

The utility model discloses a protective connection device for floor adjacent edges. A protective frame is especially used for protecting adjacent edge holes of all floors when a concrete structure is constructed. The protective connection device is formed by combining and assembling three steel sleeves, scaffold steel pipes and bolts in a sleeved mode. Screw caps are welded to the bolt hole positions of the steel sleeves and are used for bolt connection. A support steel sleeve is fixed to the upper surface of the concrete structure through expansion bolts. The horizontal scaffold steel pipes and vertical scaffold steel pipes are inserted into the steel sleeves and are connected and fixed through the bolts. The starting place of stair is formed by connecting a 150-degree steel sleeve and two horizontal scaffold steel pipes through the bolts so as to guarantee consistency and integrity of the adjacent edge protective frame. The turning corner position of the stair is formed by connecting two 90-degree steel sleeves and a short scaffold steel pipe through the bolts so as to guarantee consistency and integrity of the protective frame.
