Force-limiting fusing wind-resistant spherical support
The invention discloses a force-limiting fusing wind-resistant spherical support which comprises a sliding plate (1), a spherical crown (4), a lower support plate (6) and a base (9). The spherical crown (4) is arranged between the sliding plate (1) and the lower support plate (6), and is in sliding connection with the sliding plate (1) to form a plane friction pair, the spherical crown (4) is connected with the lower support plate (6) through a stud (13) to form a spherical friction pair; the lower support plate (6) is fixedly connected with the base (9) through a fusing mechanism, a pressingplate (10) is arranged between the lower support plate (6) and the base (9), the fusing mechanism is automatically cut off under the working condition that transverse force exceeds a threshold value,the spherical friction pair is limited through the pressing plate (10), and it is guaranteed that the support structure does not fail. Structural damage and bridge structure damage caused by overlargetransverse load of the beam body are avoided, and structural safety of the beam body is effectively guaranteed.
本发明公开了一种限力熔断抗风球型支座，包括滑动板(1)、球冠(4)、下支座板(6)和底座(9)；球冠(4)设于滑动板(1)和下支座板(6)之间，且与所述滑动板(1)滑动连接，构成平面摩擦副，所述球冠(4)与下支座板(6)之间通过螺柱(13)连接，共同构成球面摩擦副，下支座板(6)通过熔断机构与所述底座(9)固定连接，所述下支座板(6)与底座(9)之间设有压板(10)，横向力超过阈值工况下自动剪断所述熔断机构，且通过所述压板(10)限制所述球面摩擦副，保证支座结构不失效。本发明避免了梁体因横向载荷过大而导致结构破坏，损坏桥梁结构，有效保证梁体的结构安全。
