Friction and spring combined energy dissipation type bridge anti-seismic check block structure
The invention relates to the technical field of bridge earthquake resistance, in particular to a friction and spring combined energy dissipation type bridge anti-seismic check block structure. The structurecomprises a steel corbel assembly, a top plate, webs, a hollow cube and a sphere, wherein the steel corbel assembly is fixed to the upper portion of the side wall of a pier, the top plate is fixed to the bottom of a main beam, one ends of the two webs are connected with one end of the bottom of the top plate, and the other ends of the two webs are connected with the top of the steel corbel assembly; the hollow cube is of a hollow cube structure, and first dampers connected are arranged between the left outer wall and the right outer wall of the hollow cube and the inner walls of the twowebs. The sphere is arranged in an inner cavity of the hollow cube, and a second damper connected is arranged between the outer wall of the sphere and the inner cavity of the hollow cube. Overlarge displacement of the beam body and the bridge piers in the bridge direction can be limited, the beam falling phenomenon is avoided, energy is absorbed, damage of earthquakes to a bridge is reduced, and earthquake energy is absorbed.
本发明涉及桥梁抗震技术领域，尤其涉及一种摩擦与弹簧组合耗能型桥梁抗震挡块结构，包括钢牛腿组件、顶板、腹板、空心立方体以及球体，所述钢牛腿组件固定于桥墩的侧壁上方，所述顶板固定于主梁的底部，两块所述腹板的一端与所述顶板的底部一端相连，另一端与所述钢牛腿组件的顶部连接；所述空心立方体呈中空的立方体结构，所述空心立方体的左、右外壁与两块所述腹板的内壁之间设有与之连接的第一阻尼；所述球体设置于所述空心立方体的内腔中，其外壁与所述空心立方体内腔之间设有与之连接的第二阻尼。本发明能够限制梁体和桥墩的顺桥向过大位移，避免发生落梁现象，吸收能量，以至于减少地震对桥梁的损坏，吸收地震能量。
