Abstract

The invention discloses an anti-seismic and anti-overturning support for a bridge. The support comprises an upper connecting component connected with a beam body and a lower connecting component connected with a cover beam, a rubber block is arranged between the upper connecting component and the lower connecting component, the anti-seismic and anti-overturning support further comprises integrated spring steel sheet semi-circular rings, and the spring steel sheet semi-circular rings are arranged on the upper portion and the lower portion respectively. The spring steel sheet semi-circular ring A arranged on the upper portion penetrates through the rubber block and the upper connecting component, the part penetrating through the upper connecting component is in an arc shape, the spring steel sheet semi-circular ring B arranged on the lower portion penetrates through the rubber block and the lower connecting component, and the part penetrating through the lower connecting component is in an arc shape. The upper spring steel sheet semi-circular ring A and the lower spring steel sheet semi-circular ring B are oppositely arranged, and connecting pieces are arranged on the opposite portions of the upper spring steel sheet semi-circular ring A and the lower spring steel sheet semi-circular ring B correspondingly. And a spring is arranged between the connecting piece of the upper spring steel sheet semicircular ring A and the connecting piece of the lower spring steel sheet semicircular ring B.

Description

technical field [0001] The invention relates to an anti-seismic and anti-overturning bearing for a bridge. Background technique [0002] A universal damping device is disclosed in Chinese patent CN105220788A, and it is specifically disclosed that the device includes two panels and at least three limb panels, and the two panels are fixedly connected to both ends of the limb panels. There are eight limb boards. The panel is a circular, polygonal or regular polygonal steel plate. The limb board is a U-shaped steel plate. The opening of the U-shaped steel plate faces inwardly or outwardly and is fixedly connected with the panel. The connection method of the U-shaped steel plate and the panel is welding or setting bolt holes on the corresponding positions of the panel and the U-shaped steel plate to connect with bolts or the U-shaped steel plate and the panel are fixed together by welding and bolts. Although the above-mentioned structure can have an anti-seismic effect in the...
