Title:
FRICTION ENERGY DISSIPATION TYPE WIND-RESISTANT SUPPORT AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/124969
Kind Code:
A1
Abstract:
A friction energy dissipation type wind-resistant support, and a method. The support comprises a planar friction pair and a rotating friction pair, and further comprises a rotating shaft (5), a middle lining plate (6), a guide shaft (9), a first elastic body (10), a friction damper spring assembly (13) and a bottom basin assembly (14), an inner concave hole being provided in the center of a convex spherical surface of a spherical crown; the rotating shaft (5) is arranged in the center of the middle lining plate (6), and the rotating shaft (5) is inserted into the inner concave hole, so that the rotating shaft (5) may adapt to rotation of the support in a horizontal plane; the middle lining plate (6) is arranged on the bottom basin assembly (14), the guide shaft (9) is also arranged on the bottom basin assembly (14); the first elastic body (10) is sleeved on the guide shaft (9), and buffering and restoring force is provided for the movement of a main girder across a bridge by means of the first elastic body (10), which has an energy absorption effect; and the friction damper spring assembly (13) is horizontally arranged in the bottom basin assembly (14) and is perpendicular to the arrangement direction of the guide shaft (9). The function of sliding friction energy dissipation is achieved by applying a pre-tightening force to the friction damper spring assembly (13). The wind-resistant support solves the problems of an impact force on the main girder being large, and the spherical crown of the support easily falling off, under the action of transverse wind on the bridge.
