Fabricated sliding type energy dissipation steel bar anti-seismic stop block
The invention discloses an assembly type sliding energy dissipation steel bar anti-seismic stop block which comprises an assembly type stop block body and a bridge abutment. An assembly type stop block body connecting hole channel and a bridge abutment connecting hole channel are reserved in the assembly type stop block body and the bridge abutment respectively; a plurality of energy dissipation steel bars are arranged in the assembly type check block body connecting hole channels in a penetrating mode. A plurality of common steel bars are arranged in the bridge abutment connecting hole channel in a penetrating manner; one end of the common steel bar extends into the bridge abutment; the energy dissipation steel bars are connected with the common steel bars through bolts; cast-in-place concrete is arranged at the joint of the energy dissipation steel bar and the common steel bar between the assembly type stop block body and the bridge abutment; a dry construction joint isolation layer is arranged in a joint between the cast-in-place concrete and the assembly type stop block body. Assembling construction is convenient and fast, under an earthquake, the force transmission mechanism of the stop blocks is clear, ductility reserve is sufficient, and the energy dissipation capacity is outstanding, so that the limiting function is improved, damage to a bridge abutment/a cover beam and a pier stud cannot be increased, and the functions of multi-stage fortification and multi-stage energy dissipation can be achieved; and the post-earthquake repair and replacement are convenient.
本发明公开了一种装配式滑移型耗能钢棒抗震挡块，包括装配式挡块体和桥台；装配式挡块体和桥台上分别预留有装配式挡块体连接孔道和桥台连接孔道；装配式挡块体连接孔道中穿设有多根耗能钢棒；桥台连接孔道中穿设有多根普通钢棒；普通钢棒的一端伸入桥台的内部；耗能钢棒与普通钢棒通过螺栓连接；位于装配式挡块体和桥台之间的耗能钢棒与普通钢棒的连接处有现浇混凝土；现浇混凝土与装配式挡块体之间的接缝中设置有干施工缝隔离层。本发明装配施工便捷，在地震下挡块传力机理明确、延性储备充分、耗能能力突出，从而限位功能提高，并且不会加重桥台/盖梁及墩柱的损伤，还能实现多级设防及多级耗能的功能；震后便于修复及更换。
