Description
Technical field
The utility model relates to a kind of neoprene bearing, and shock insulation rubber bearing that specifically can anti-pulling belongs to building cushion technique field.
Background technology
China is one of country that seismic activity is in the world the strongest and earthquake disaster is the most serious.Shock insulation rubber bearing applies in various building constructions, highway bridge and structural strengthening, adopts multilayer steel plates and the multilayer rubber good adhesion that is superimposed, and has good horizontal performance, damped coefficient, the vertically series of advantages such as performance and vertical bearing capacity.But this shock insulation rubber bearing can only bear the pressure that transmit on top, the ability of bearing tension.When Seismic Isolation of Isolation Layer bearing tension enters surrender, can cause structural entity to occur overturning.Therefore, at standard GB/T 50011-2001 < < seismic design provision in building code > > 12.2.4 bar, in first item, clearly stipulate that " Seismic Isolation of Isolation Layer neoprene bearing, under rarely occurred earthquake effect, should not occur pulling force." but some building, under rarely occurred earthquake effect, shock isolating pedestal occurs that tensile stress is normal phenomenon, a lot of buildings or bridge, have the existence of tensile stress.Thereby this deficiency of shock insulation rubber bearing has limited the scope of application of shock insulation rubber bearing and has applied.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of anti-pulling shock insulation rubber bearing is provided, and has anti-pulling function, has the larger horizontal movement of all directions in larger vertical bearing capacity and plane simultaneously.
The technical scheme providing according to the utility model, anti-pulling shock insulation rubber bearing comprises lower connecting plate, upper junction plate and bearing core body, it is characterized in that: between lower connecting plate and upper junction plate, by bearing core body, link into an integrated entity.Lower connecting plate soffit is provided with spring gathering sill, in four limit grooves of formation spring gathering sill, is respectively provided with a leaf spring.Leaf spring center connects adjusting screw(rod), and adjusting screw(rod) upper end connects cable wire, and cable wire upper end is fixed on upper junction plate through lower connecting plate.
Further, bearing core body be take the center of lower connecting plate and upper junction plate and is uniformly distributed as the center of circle.
Further, bearing core body comprises a plurality of steel plate layers and a plurality of rubber layer, and a plurality of steel plate layers and the alternately laminated bonding connection of a plurality of rubber layer are integral.
Further, between bearing core body and lower connecting plate, upper junction plate, be bolted.
Further, spring gathering sill is rectangle.
Further, the locking nut locked position that adjusting screw(rod) connects by lower end.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, compact, reasonable, easy for installation, safeguards simply long service life; When playing overturn-preventing effect and horizontal seismic isolation effect, certain horizontal rigidity can be provided, the destruction of earthquake to building can be more effectively reduced.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is AA sectional view in Fig. 1.
Description of reference numerals: 1-lower connecting plate, 2-leaf spring, 3-spring gathering sill, 3.1-limit groove, 4-upper junction plate, 5-bearing core body, 6-cable wire, 7-adjusting screw(rod), 8-locking nut.
The specific embodiment
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Figure 1 and 2, the utility model mainly comprises lower connecting plate 1, upper junction plate 4 and bearing core body 5, between lower connecting plate 1 and upper junction plate 4, by bearing core body 5, link into an integrated entity, bearing core body 5 be take the center of lower connecting plate 1 and upper junction plate 4 and is uniformly distributed as the center of circle.Between described bearing core body 5 and lower connecting plate 1, upper junction plate 4, be bolted.
Described bearing core body 5 comprises a plurality of steel plate layers and a plurality of rubber layer, and a plurality of steel plate layers and the alternately laminated bonding connection of a plurality of rubber layer are integral.
Lower connecting plate 1 soffit is provided with the spring gathering sill 3 of rectangle, in four limit grooves 3.1 of formation spring gathering sill 3, is respectively provided with a leaf spring 2.Spring gathering sill 3 offers the transverse displacement space that leaf spring 2 compressions produce, and guarantees that leaf spring 2 deformation position are not offset simultaneously.
Leaf spring 2 centers connect adjusting screw(rod) 7, and adjusting screw(rod) 7 upper ends connect the high-intensity cable wire 6 of anti-pulling, and cable wire 6 upper ends are fixed on upper junction plate 4 through lower connecting plate 1.Locking nut 8 locked positions that described adjusting screw(rod) 7 connects by lower end.By adjusting adjusting screw(rod) 7, to cable wire 6, regulate pretightning force, guarantee stress balance.
Operating principle of the present utility model is: when bearing produces horizontal movement, cable wire also produces certain horizontal sextant angle displacement, the compression of drive leaf spring, cable wire is extended, make vertical displacement be converted to horizontal movement, bearing can be produced compared with large displacement and unrestricted in all directions, and bearing core body produces horizontal movement and is out of shape to reduce the infringement to building.
While producing tensile stress in bearing, cable wire can drive leaf spring 2 compressions, certain pulling capacity is resisted and cushioned to self rigidity of leaf spring 2, when the pulling force that upwards draws displacement to can bear over bearing core body more greatly, cable wire will play upwards displacement restriction effect, play anti-pulling, the effect of overturn-preventing.
The utility model is simple in structure, compact, reasonable, easy for installation, safeguards simply long service life; When playing overturn-preventing effect and horizontal seismic isolation effect, certain horizontal rigidity can be provided, the destruction of earthquake to building can be more effectively reduced.
