the anti-falling clamping piece consists of a cross rod, an inclined rod and an inserting rod, the cross rod, the inclined rod and the inserting rod are of an integral structure, and the inserting rod is vertically connected with the inclined rod;
the inserted bar is inserted into the slot or the jack on the screw rod, and the cross rod is inserted into the strip-shaped groove at the bottom of the fastening bolt.
The steel structure fastener for building site, the groove width in bar groove be greater than the horizontal pole diameter of anticreep fastener, bar groove and slot or jack be parallel structure and arrange on locking bolt.
The steel structure fastener for the construction site, the locking bolt pass in the jack of two risers on crossbeam web and the girder support frame respectively.
The steel structure fastener for the construction site is characterized in that a gasket is sleeved on the locking bolt and is fixed through a locking nut.
The utility model discloses the beneficial effect who reaches is:
1. the utility model discloses with fastening bolt, lock nut and anticreep fastener make up the use, at first the bar groove has been seted up in the bottom of fastening bolt's screw rod, slot or jack have been seted up on the face of shank of bolt, when carrying out steel construction installation, at first pass the riser jack of crossbeam web and supporting the girder structure respectively with fastening bolt, then embolia the gasket on fastening bolt's screw rod, lock nut on the screw rod, then insert the horizontal pole of anticreep fastener bottom in the bar groove of locking bolt bottom, because the anticreep fastener adopts the cross-section to be circular shape stainless steel metallic structure, itself has certain toughness and elasticity, then open the down tube of anticreep fastener, it is parallel to make between two down tubes, two inserted bars that are connected with the down tube this moment are also close with the plane and are parallel structure, then insert the inserted bar in jack groove or the jack on the screw rod, fix between fastener and the fastening bolt this moment, can prevent through setting up the anticreep fastener that lock nut from coming off from fastening bolt.
2. The utility model has the characteristics of simple structure, be convenient for production and processing, convenient operation etc, only need to fix the anticreep fastener and can prevent that lock nut from droing on fastening bolt, at the tip processing of slot or jack conical surface structure simultaneously, increase the diameter of inserted hole through setting up conical surface structure to can make things convenient for more quick the inserted bar with on the anticreep fastener to insert in slot or jack.
