The utility model relates to an isolation anchor bolt, which comprises a screw and a cone cap. The screw is successively covered with a cone cap, an expansion sleeve, a shock isolation sleeve, a shear resistant tube, a gasket and an installation nut from the head to the tail. The expansion sleeve includes an expansion tube, a friction plate, a brake gap at the tail of the expansion tube, a brake claw at the front end of the isolation sleeve and a shock isolation sleeve package. Including front reinforcing ring, rear reinforcing ring and deformation sleeve, the deformation sleeve has deformation through hole, the outer wall of the front reinforcing ring has anti-skid claws, the isolation sleeve is nylon material, and the screw tail has cross groove. The nylon isolation sleeve in the utility model is spreaded outward by the torsional force acting on the screw-shaped through holes arranged on the surface, effectively preventing the expansion sleeve from following up during installation, facilitating installation, and the brake claw helps to prevent the expansion sleeve from turning. The scattered isolation sleeve has more toughness, which will make the screw tail as well as the screw tail. Kinetic energy absorbed from shear resistant tube reduces vibration transmitted to expansion sleeve, and conical sleeve with cross groove and thread connection facilitates the disassembly of anchor bolt.

一种隔震锚栓
本技术涉及紧固件领域,特别涉及一种隔震锚栓。
技术介绍
现有普通STG式重型锚栓的锥帽采用普通的圆锥台结构,单一斜面导致摩擦片膨胀幅度小,动载荷易于传到到摩擦片处,抵抗动荷载能力差;现有重型锚栓采用塑料防松圈,结构较单一,在锚栓受到安装扭力后,防松圈与混凝土孔壁摩擦力不会增大,容易引起自转,影响膨胀效果。
