Bridge structure with transverse shock absorption and isolation supporting system
The invention relates to a bridge structure with a transverse shock absorption and isolation supporting system, and belongs to the technical field of bridge shock absorption, the bridge structure comprises a bridge tower and a main beam, the bridge tower comprises two tower columns and a bridge tower cross beam located between the two tower columns, and the main beam is located between the two tower columns and located at the top of the bridge tower cross beam; a transverse support is located between the main beam and the tower column, one end of the transverse support is fixedly connected with the main beam, and the other end of the transverse support can make contact with the tower column and longitudinally slide; and a transverse damper is located between the main beam and the tower column, one end of the transverse damper is connected with the main beam, the other end of the transverse damper does not make contact with the tower column, and after the transverse support is cut off, the other end of the transverse damper makes contact with the tower column all the time and is in sliding connection with the tower column. According to the bridge structure, when the transverse support reaches the rated shearing force and stops working, the transverse damper starts to intervene and exert the energy dissipation and shock absorption effect, and the purposes of shock absorption and energy dissipation are achieved. Bolt holes do not need to be formed in webs of girders, additional connecting plates do not need to be welded to top plates or bottom plates of the girders, and the durability of the girders is higher.
本申请涉及一种具有横向减隔震支撑体系的桥梁结构，属于及桥梁减震技术领域，包括：桥塔和主梁，桥塔包括两根塔柱和位于两根塔柱之间的桥塔横梁，主梁位于两根塔柱之间且位于桥塔横梁的顶部；横向支座，其位于主梁和塔柱之间，其一端与主梁固定连接，其另一端与塔柱可接触并纵向滑动；横向阻尼器，其位于主梁和塔柱之间，其一端与所述主梁连接，其另一端与塔柱不接触，当横向支座剪断后，横向阻尼器的另一端始终与塔柱接触并滑动连接。本申请的桥梁结构当横向支座达到额定剪断力而退出工作，横向阻尼器开始介入并发挥耗能减震作用，达到减震耗能的目的。主梁的腹板无需开设螺栓孔，主梁的顶板或底板不需焊接附加连接板件，主梁耐久性更好。
