Design scheme of quake resistance anchor bolt
Disclosed is a design scheme of a quake resistance anchor bolt. The quake resistance anchor bolt is composed of a steel bar, an anchor bolt, a plastering layer and concrete base material. The design scheme of the quake resistance anchor bolt is characterized by selecting a chemical embedded steel bar, and a chambering type anchor bolt or a torque control type expansion type bolt, which can prevent an expansion piece from loosing, and arranging the chemical embedded steel bar, and the chambering type anchor bolt or the torque control type expansion type bolt, which can prevent the expansion piece from loosing, on a pressure area or a non-fracture area of a construction member, and not on a plain concrete area, and for anchoring connections of important structural members for the first level quake resistance on a high intensity seismic area, arranging the chemical embedded steel bar, and the chambering type anchor bolt or the torque control type expansion type bolt, which can prevent the expansion piece from loosing, on an area surrounded by vertical and horizontal steel bars, and reasonably selecting the anchoring depth and anchoring parameters such as edge distances and intervals, or adopting effective quake insulation and energy dissipation measures, and achieving ductility damage for an anchoring connection system, and furthermore for structural members under combined action of tension, edge shearing and tensile shearing, preventing damage to the concrete base material and damage to the anchor when the anchor is pulled out from occurring.
