Integral abutment-steel pipe concrete pile joint of lead core laminated rubber device
The invention relates to an integral abutment-steel pipe concrete pile joint of a lead core laminated rubber device. The integral abutment-steel pipe concrete pile joint comprises a concrete abutmentand a steel pipe concrete pile, the integral abutment-steel pipe concrete pile joint is characterized in that a lead core laminated rubber device is arranged at the top of the steel pipe concrete pile, the lead core laminated rubber device comprises laminated rubber and at least one lead core, the laminated rubber is formed by alternately laminating rubber sheets and stiffening steel plates in alayered mode, and a hole used for containing the lead core is formed in the laminated rubber. The invention further provides a construction method of the joint. The joint deformation capacity and theenergy absorption capacity can be improved, the joint deformation recovery time is shortened, and post-earthquake residual displacement is reduced.
本发明涉及一种铅芯叠层橡胶装置的整体式桥台‑钢管混凝土桩节点，包括混凝土桥台和钢管混凝土桩，其特征在于，在钢管混凝土桩的顶部设置铅芯叠层橡胶装置，所述的铅芯叠层橡胶装置包括叠层橡胶和至少一个铅芯，所述叠层橡胶由橡胶片和加劲钢板分层交替叠合而成，在层叠橡胶内设置有用于容纳铅芯的孔洞。本发明同时提供一种此种节点的施工方法。本发明能够提高节点变形能力和能量吸收能力，加速节点变形恢复时间，降低震后残余位移。
