Abstract
Rubber bridge beam supports with protection device is moved to side, including last bedplate, lower bedplate and rubber support, rubber support lies in between bedplate and the lower bedplate, rubber support is provided with the rubber protective layer outward, and upward bedplate and lower bedplate edge are provided with the baffle, are provided with the rubber dog between baffle and the rubber support, is provided with the projection in the one side that upward bedplate and lower bedplate and rubber support contacted. The utility model discloses simple structure, convenient to use, the difficult horizontal displacement that takes place.
Description
Technical field
The utility model relates to a kind of bridge pad, is especially with the rubber bridge support of side moves protective device.
Background technology
Bridge pad, is set up on pier, the device of end face supporting bridge superstructure.Its function, for superstructure is fixed on pier, is born the various power acting on superstructure, and it is reliably passed to pier.Under load, temperature, concrete shrinkage and creep effect, bearing can adapt to corner and the displacement of superstructure, makes superstructure can Free Transform and do not produce extra additional internal force.At present, good with its damping characteristic for the laminated rubber bearing below highway, railroad bridge beam body, bearing capacity is high and be widely used.But common laminated rubber bearing bears the function of vertical force for master, horizontal force mainly relies on frictional resistance to bear, usually only have about 15% of vertical force, in use easily produce larger horizontal movement and destroying because of horizontal earthquake power, vehicular impact power.
Summary of the invention
The purpose of this utility model overcomes the problem that the easy occurred level displacement of laminated rubber bearing in prior art causes bearing to damage, and provides the rubber bridge support of a kind of structure band sidesway that is simple, easy to use, not easily occurred level displacement protective device.
For realizing above object; technical solution of the present utility model is: the rubber bridge support of band side moves protective device; comprise upper base plate, lower seat board and neoprene bearing; described neoprene bearing is between upper base plate and lower seat board; described neoprene bearing is outside equipped with rubber cover; upper base plate and lower seat board edge are provided with baffle plate, are provided with rubber block between baffle plate and neoprene bearing, and the one side that upper base plate and lower seat board contact with neoprene bearing is provided with projection.
Described baffle plate is curved baffle.
The height of described projection is not more than 8 millimeters.
The utility model compared with the existing technology has following beneficial effect:
1, in the design, upper base plate and lower seat board edge are provided with baffle plate, rubber block is provided with between baffle plate and neoprene bearing, when bearing is subject to the displacement of horizontal force occurred level, rubber block can stop the horizontal movement of neoprene bearing, even if neoprene bearing breaches rubber block, because upper base plate and lower seat board edge are provided with baffle plate, and baffle plate is curved baffle, can well stop neoprene bearing to outer displacement.
2, the one side that in the design, upper base plate and lower seat board contact with neoprene bearing is provided with projection, and the height of projection is not more than 8 millimeters, under the effect of bridge pier gravity, projection tightly can compress into neoprene bearing, make upper base plate, between lower seat board and neoprene bearing, keep compact siro spinning technology, the effect stoping neoprene bearing horizontal movement can be played.
3, in the design, neoprene bearing is outside equipped with rubber cover, and when the displacement of neoprene bearing occurred level, what first contact with baffle plate is rubber cover, avoids neoprene bearing and contacts with the direct of baffle plate, can available protecting neoprene bearing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the lateral view of upper base plate in the utility model.
In figure: upper base plate 1, lower seat board 2, neoprene bearing 3, rubber cover 4, baffle plate 5, rubber block 6, projection 7.
Detailed description of the invention
Illustrate below in conjunction with accompanying drawing and with detailed description of the invention, the utility model to be described in further detail:
See Fig. 1 and Fig. 2; with the rubber bridge support of side moves protective device; comprise upper base plate 1, lower seat board 2 and neoprene bearing 3; described neoprene bearing 3 is between upper base plate 1 and lower seat board 2; described neoprene bearing 3 is outside equipped with rubber cover 4; upper base plate 1 and lower seat board 2 edge are provided with baffle plate 5, are provided with rubber block 6 between baffle plate 5 and neoprene bearing 3, and the one side that upper base plate 1 and lower seat board 2 contact with neoprene bearing 3 is provided with projection 7.
Described baffle plate 5 is curved baffle.
The height of described projection 7 is not more than 8 millimeters.
In the design, upper base plate 1 and lower seat board 2 edge are provided with baffle plate 5, rubber block 6 is provided with between baffle plate 5 and neoprene bearing 3, when bearing is subject to the displacement of horizontal force occurred level, rubber block 6 can stop the horizontal movement of neoprene bearing 3, even if neoprene bearing 3 breaches rubber block 6, because upper base plate 1 and lower seat board 2 edge are provided with baffle plate 5, and baffle plate 5 is curved baffle, can well stop neoprene bearing 3 to outer displacement.The one side that in the design, upper base plate 1 and lower seat board 2 contact with neoprene bearing 3 is provided with projection 7, and the height of projection 7 is not more than 8 millimeters, under the effect of bridge pier gravity, projection 7 can tightly compress into neoprene bearing 3, make upper base plate 1, between lower seat board 2 and neoprene bearing 3, keep compact siro spinning technology, the effect stoping neoprene bearing 3 horizontal movement can be played.In the design, neoprene bearing 3 is outside equipped with rubber cover 4, and when neoprene bearing 3 occurred level displacement, what first contact with baffle plate 5 is rubber cover 4, avoids neoprene bearing 3 and contacts with the direct of baffle plate 5, can available protecting neoprene bearing 3.The utility model structure is simple, easy to use, not easily occurred level displacement.
