Description

From the supertronic bearing

Technical field:

The utility model relates to a kind of bridge damping device, particularly a kind of neoprene bearing.

Background technology:

Bearing generally has and can carry as superstructure weight such as bridge, buildings, adapts to the function that its rotation that produces and needs slide; When not needing to slide, select fixed bearing, select unidirectional freely movable bearing in the time of only sliding in one aspect, select two-way sliding support when vertical and horizontal all can slide.

The product commonly used that can realize the above bearing function has laminated rubber bearing, pot rubber bearing, spherical bearing, rod shaft stool etc., and they respectively have its pluses and minuses and use compliance.

Big corner be adjusted and be adapted to pot rubber bearing can not, spherical bearing does not have damping performance and designs generation in order to overcome from the supertronic bearing, divide three types of fixed bearings, unidirectional freely movable bearing, bi-directional movable bearing from the supertronic bearing, it is big to have bearing capacity, rotate flexibly, the angle of upper plate that can adjust bearing is to adapt to the characteristics such as gradient needs of bridge or top-out.Utility model patent " title: " from the supertronic neoprene bearing ", notice of authorization number are: CN2563184Y " promptly is wherein a kind of.

Bridge in use, beam is known from experience because of external force (operating car, wind) concrete convergent-divergent or when cold and hot and produce displacement with respect to bridge pier, this displacement should be adapted to by freely movable bearing, susceptor design was not at that time, the generation of this displacement must cause that the strong point changes, will occur being subjected to displacement when the beam body, the weight of beam and superstructure departs from the center and bridge pier is produced additional bending moment, the big more additional bending moment of displacement or weight is big more, these moments of flexure have produced extremely harmful effect to bridge pier, when beam comes and goes activity, additional bending moment also returns and acts on pier again thus, will produce serious bending failure to the root structure of pier.Bridge pier is high more, and this moment of flexure is big more to the harm of bridge pier.Above-mentioned " from the supertronic neoprene bearing " though the angle of upper plate that can adjust bearing to adapt to the gradient of bridge or top-out, but also have the following disadvantages: because the device of its sliding friction pair is in the bearing bottom, when the beam body because of external force (operating car, wind) concrete convergent-divergent or when cold and hot and when producing displacement with respect to bridge pier, whole bearing will move with the beam body, the beam body produces displacement at the strong point of beam-ends with respect to bridge pier, and will produce additional bending moment M, extremely unfavorable to bridge security (referring to Fig. 3～Fig. 4, Fig. 3 is that support friction pair is located at the bearing bottom, the additional bending moment M that the beam body produces when displacement is arranged, Fig. 4 are the situations that the beam body does not have displacement).

The utility model content:

The technical problems to be solved in the utility model is: provide a kind of from the supertronic bearing, this bearing both can be by having adjusted the bearing upper plate angle with the gradient that adapts to bridge or top-out, its bearing upper plate can also with the beam body move adjust the beam body at the strong point of beam-ends with respect to the displacement that bridge pier produces, avoid the generation of additional bending moment.

The technical scheme that solves its above-mentioned technical problem is: a kind of from the supertronic bearing, comprise base-plate, rubber tile, steel liner plate, arc piece, the annular seal space that the cylinder shape groove of base-plate and steel liner plate are formed seals rubber tile, the upper surface of steel liner plate cooperates with the arc soffit cambered surface of arc piece, be provided with the bearing upper plate on the arc piece, the upper surface of arc piece and bearing upper plate soffit are slidingly matched.

Further technical scheme of the present utility model is: the tetrafluoro slide plate that is embedded in arc piece upper surface has been formed the planar slide friction pair with the corrosion resistant plate that is welded on bearing upper plate soffit.

Further again technical scheme of the present utility model is: the upper surface of described steel liner plate is the face of cylinder or sphere, and the upper surface of steel liner plate is that the face of cylinder or sphere cooperate with the arc soffit of arc piece.

Further again technical scheme of the present utility model is: the described side tetrafluoro slide plate that is embedded in arc piece side has been formed the side slip friction pair with the side corrosion resistant plate that is welded on bearing upper plate side.

Because adopt technique scheme, comparing with existing " from the supertronic neoprene bearing " from the supertronic bearing of the utility model has following beneficial effect:

This programme adopted the curved upper surface of steel liner plate to cooperate from the supertronic bearing with the arc soffit face of cylinder or the sphere of arc piece, thereby the angle of upper plate that can adjust bearing is to adapt to the gradient of bridge or top-out, particularly support friction pair being located at bearing top---the corrosion resistant plate that is welded on the bearing upper plate has been formed the planar slide friction pair with the tetrafluoro slide plate that is embedded in arc piece upper surface, when the beam body produces displacement, the bearing upper plate of band corrosion resistant plate friction pair moves with the beam body, and another arc piece of wearing tetrafluoro slide plate friction pair is not because of producing displacement, though the beam body has produced displacement at the strong point of beam-ends with respect to bridge pier, but the gravity of bridge or building can be because of the generation displacement of pier relatively of its displacement, the gravity of bridge or building still remains on the center of former pier, thereby there is not an additional bending moment, can not produce harmful effect (referring to Fig. 5: support friction pair is located at bearing top, and the beam body has displacement but do not have additional bending moment) to bridge pier.

Below, the technical characterictic from the supertronic bearing to the utility model is further described in conjunction with the accompanying drawings and embodiments.
