Technical Field
The utility model relates to a civil construction technical field specifically indicates an one-way activity pot rubber support that possesses tensile and limit function.
Background
The support is a functional component for connecting the main beam and the pier. The main beam of the bridge can stretch out and draw back and rotate in the work under the effects of dead weight, temperature, earthquake and the like, and the bridge support can eliminate the limitation of the pier on the deformation of the main beam through a proper structure, so that the main beam can freely stretch out and draw back and rotate.
The bridge support can be divided into three types according to the movement characteristics, namely, a fixed support can meet the requirement of the rotation of the main beam, but cannot slide in the length direction and the width direction of the main beam; the unidirectional movable support can meet the rotation function, limit the displacement of the bridge girder along the width direction, enable the bridge girder to bear the horizontal load of the girder and adapt to the movement of the girder along the length direction of the bridge; and thirdly, the bidirectional sliding support can meet the rotation function and move along the length direction and the width direction of the bridge. The bridge bearing can be divided into a steel bearing and a rubber bearing according to materials, at present, rubber bearings are mainly used in China, and a one-way basin-type rubber bearing is one of the most common bearings.
The unidirectional movable basin-type rubber support mainly comprises a bottom basin, a rubber plate on the bottom basin, a middle steel plate, a tetrafluoro plate, a stainless steel sliding plate fixed on an upper top plate, a top plate and lateral steel bars on two non-movable sides of the top plate, wherein the middle steel plate and the tetrafluoro plate are sequentially fixed on the rubber plate. The top plate and the main beam are fixed through anchor bolts, and the bottom basin is fixed with the bridge pier through anchor bolts. The rubber support can realize the rotation of the main beam of the bridge by the characteristic that the rubber plate has fluid in a three-dimensional stress state, and meanwhile, the displacement of the main beam in the moving direction of the length direction of the bridge is realized by the low friction coefficient between the tetrafluoro plate and the stainless steel sliding plate, so that the force born by the rubber support in the length direction of the bridge is not completely borne by the rubber plate, but indirectly acts on the sliding between the tetrafluoro plate and the stainless steel sliding plate, and in addition, lateral steel bars on two non-moving sides of the top plate limit the non-moving direction movement of the main beam in the width direction of the bridge. Under the action of earthquake load, the existing one-way movable basin-type support can only transmit little horizontal earthquake force through friction between the tetrafluoro plate and the stainless steel plate, the movement is limited to displacement without a special device, and unrecoverable overlarge displacement is easy to occur in the earthquake, so that the problems of beam falling, overturning and the like are caused, and huge economic loss is caused.
