Connecting structure of socket and spigot type pier column and bearing platform of assembly type bridge
The invention relates to an assembly type bridge socket type pier column and bearing platform connecting structure which comprises a pier column and a bearing platform, a socket groove used for containing the pier column is formed in the bearing platform, a first steel sleeve is arranged on the inner wall of the socket groove in advance, and first shear keys arranged in order are arranged on the inner wall of the first steel sleeve; a first steel sleeve is pre-arranged at the end, inserted into the socket groove, of the pier column, a second steel sleeve is pre-arranged at the end, inserted into the socket groove, of the pier column, second shear keys which are arranged in order are arranged on the outer wall of the second steel sleeve, the first shear keys and the second shear keys are arranged in a staggered mode, a gap between the first steel sleeve and the second steel sleeve is a grouting part, and the grouting part is used for secondary grouting; according to the connecting structure, the requirement for mounting and positioning precision can be effectively lowered on the premise that the structural integrity is guaranteed, the shearing resistance of the grouting part is improved, the mechanical property of the grouting part is reliable, chiseling noise is avoided, the using amount of concrete is saved, and the working efficiency is improved.
本发明涉及一种装配式桥梁承插式墩柱与承台连接结构，包括墩柱和承台，所述承台上设置有用以容纳所述墩柱的承插槽，承插槽的内壁预置有第一钢套管，所述第一钢套管的内壁设置有排列整齐的第一抗剪键，所述墩柱插入承插槽内的一端预置有第二钢套管，所述第二钢套管的外壁设置有排列整齐的第二抗剪键，所述第一抗剪键与所述第二抗剪键错位设置，所述第一钢套管与所述第二钢套管之间的间隙为灌浆部，所述灌浆部用以二次灌浆；所属连接结构在保证结构整体性的前提下能有效降低安装定位精度要求，提高灌浆部位的抗剪性能，且灌浆部位的力学性可靠，无凿毛噪声，节约了混凝土的用量，加快工作效率。
