Detailed Description

The present invention will be further described with reference to the accompanying drawings by way of preferred embodiments. The utility model provides a rag bolt subassembly mainly is applicable to the construction installation of steel column base.

As shown in fig. 1, the anchor bolt assembly provided by the present invention comprises a guide cone 1, a screw rod 2, a fastening nut 3, a sleeve 5 and a supporting block 6.

The end of the screw rod 2 and the sleeve 5 which are embedded in the foundation is a first end, and the end extending out of the foundation is a second end. The supporting block 6 is provided with a through hole for the screw rod 2 to pass through, the supporting block 6 and the first end of the sleeve 5 are fixedly welded, and the first end of the screw rod 2 sequentially passes through the sleeve 5 and the supporting block 6. At the first end of the screw rod 2, one or more anti-pulling nuts 7 are spirally connected to the screw rod 2, the end face of the screw rod 2 is enabled to be flush with the end face of the anti-pulling nut 7, and the anti-pulling nut 7 is used for enhancing the anti-pulling capacity of the foundation bolt assembly and guaranteeing the stability of a steel column.

The embodiment of the utility model provides a select the steel sheet preparation supporting shoe 6 that 12mm is thick for use to set up the diameter slightly and be greater than the through-hole of screw rod diameter at supporting shoe 6 central point, select for use two resistance to plucking nuts 7, in construction work, with the first end of screw rod 2, the first end of sleeve pipe 5 and supporting shoe 6 and resistance to plucking nut 7 all pre-buried in basis 8. The second end of screw rod 2 stretches out the outside that sleeve pipe 5 second was held, and outside sleeve pipe 5's second end stretched out basic 8, 2 second end centers welded fastening guide cone 1 of screw rod, guide cone 1 is used for guide screw rod 2 to pass the column base bolt hole of seting up on the column foot board 10, measures the distance between rag bolt in the convenient construction.

The rag bolt subassembly still contains apron 4, it makes it pass

guide cone

1 and 2 second ends of screw rod to have seted up the through-hole on the apron 4, the plane area of apron 4 slightly is greater than the port of sleeve pipe 5 to cover the port of 5 second ends of sleeve pipe, prevent that sleeve pipe 5 from getting into impurity in the construction, influencing the closely knit intensity of the grout material of later stage and the intensity of screw rod 2.

The foundation bolt assembly further comprises an adjusting nut 9, the adjusting nut 9 penetrates through the second end of the screw rod 2 and is in threaded connection with the screw rod 2, and the position of the column foot plate 10 on the screw rod 2 is controlled through the adjusting nut 9 in the construction and installation process of the steel column foot.
