Shock absorption and isolation support for bridge

Abstract

The invention relates to the technical field of bridge accessories and particularly relates to a shock absorption and isolation support for a bridge. The support comprises an abutment, a bridge floor, an upper pressing plate, a lower pressing plate, a first spring, a second spring, an upper sleeve and a lower sleeve, wherein the upper sleeve is fixedly arranged in the middle of the bottom end of the upper pressing plate, and the lower sleeve is fixedly arranged at the top end of the lower pressing plate; a bottom end of the upper sleeve is fixedly connected with the top ends of the multiple sets of first springs, a connecting block is arranged in the middle of the inner top end of the upper sleeve, a buffer block is arranged at the inner bottom end of the lower sleeve, the connecting block makes contact with the buffer block, and sleeves are arranged on the peripheral sides of the bottom end of the upper pressing plate; round grooves are correspondingly formed in the circumferential sides of the top ends of the lower pressing plates, and the four sets of sleeves extend into the four sets of round grooves from the top ends of the four sets of round grooves correspondingly and are in sliding connection with the four sets of round grooves. The bridge damping device can effectively damp a bridge, relieve pressure borne by the bridge, avoid collapse of the bridge and improve safety.

Description

technical field [0001] The invention relates to the technical field of bridge accessories, in particular to a shock-absorbing and isolating support for bridges. Background technique [0002] As we all know, the bridge bearing is an important structural component connecting the upper structure and the lower structure of the bridge. It is located between the bridge and the pad stone. force device, which has been widely used in the field of bridge accessories; the existing bridge bearings lack the shock absorption effect, and when the bridge is subjected to high pressure and vibration, the pressure on the bridge cannot be relieved, which will easily lead to the collapse of the bridge The danger, safety reduces, meanwhile, the life-span of prior art shock-absorbing bearing is limited, and the main reason is that some parts such as spring are easy to damage. [0003] For this reason, a vibration-absorbing and isolating bearing for bridges is proposed. Contents of the invention...
