Tensile sliding rubber support
The invention discloses a tensile sliding rubber support. The rubber support is characterized in that a tensile mechanism and a sliding mechanism are arranged between an upper steel plate and a lower steel plate which are connected to the upper part and the lower part of a support body; the tensile mechanism comprises a left tensile mechanism and a right tensile mechanism which are symmetrically arranged between the upper steel plate and the lower steel plate on the left side and the right side of the support body; an upper tensile steel part and a lower tensile steel part which are respectively connected with an upper steel plate and a lower steel plate are further included, a lower end of the upper tensile steel part and an upper end of the lower tensile steel part are mutually buckled to form a tensile mechanism, and an inner angle formed by buckling surfaces is an acute angle; the sliding mechanism comprises a plane sliding pair, a horizontal sliding pair and a limiting sliding pair, the plane sliding pair is arranged between the upper steel plate and the support body, and the horizontal sliding pair and the limiting sliding pair are arranged between the buckling faces of the upper tensile steel piece and the lower tensile steel piece. The support can provide required bearing capacity in a normal state, can provide tensile resistance in the vertical direction in a strong earthquake, and has the functions of limiting on the left side and the right side and sliding in the main displacement direction, so safety of the sliding support and a bridge structure is improved.
一种抗拉滑动橡胶支座，连接在支座本体上下的上钢板和下钢板之间设有抗拉机构和滑动机构：所述抗拉机构包括对称布置于支座本体左右两侧的上钢板与下钢板之间的左、右抗拉机构，包括分别与上、下钢板连接上抗拉钢件和下抗拉钢件，上抗拉钢件的下端与下抗拉钢件的上端相互扣合形成抗拉机构，其扣合面构成的内角为锐角；所述滑动机构包括平面滑动副、水平滑动副和限位滑动副，平面滑动副设在上钢板与支座本体之间，水平滑动副和限位滑动副设在上抗拉钢件与下抗拉钢件的扣合面之间。该支座在常态下可提供所需的承载力，在强震下能提供竖直方向的抗拉力，同时具有左右侧限位且主位移方向可滑动的功能，提高了滑动支座和桥梁结构的安全性。
