Abstract

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.

Description

technical field

[0001] The invention belongs to the technical field of bridge supports, and more specifically relates to a force-limited fusing anti-wind ball support. Background technique

[0002] Along with the needs of the development of our country's national economy, a number of cable-stayed bridges and suspension bridges with large span and large bearing capacity have been designed and constructed one after another. These cable-stayed bridges and suspension bridges are vertically installed with wind-resistant bearings between the inner side of the tower and the outer side of the girder, and the wind-resistant bearings are respectively anchored and connected with the tower body and the beam body. The wind-resistant bearing can limit the large-distance swing of the horizontal bridge of the beam body caused by wind or earthquake force, bear the horizontal horizontal force transmitted by the beam body, and at the same time meet the longitudinal bridge displacement and vert...
