Description
Technical field
The present invention relates to a kind of rubber support, specifically can the shock insulation rubber bearing of anti-pulling, belong to building cushion technique field.
Background technology
China is one of country that seismic activity in the world is the strongest and earthquake disaster is the most serious.Shock insulation rubber bearing applies in various building construction, highway bridge and structural strengthening, uses multilayer steel plates and multilayer rubber to be superimposed good adhesion, has the series of advantages such as good horizontal performance, damped coefficient, vertical performance and vertical bearing capacity.But this shock insulation rubber bearing can only bear the pressure of top transmission, bears the ability of pulling force.When Seismic Isolation of Isolation Layer bearing tension enters surrender, can cause structure entirety that overturning occurs.Therefore, standard GB/T 50011-2001 " seismic design provision in building code " the 12.2.4 article, in first item, ", under rarely occurred earthquake effect, should not there is pulling force to clear stipulaties in Seismic Isolation of Isolation Layer rubber support." but some building, under rarely occurred earthquake effect, shock isolating pedestal occurs that tension is normal phenomenon, and a lot of buildings or bridge have the existence of tension.Thus, this deficiency of shock insulation rubber bearing limits range and the popularization and application of shock insulation rubber bearing.
Summary of the invention
It is an object of the invention to overcome above-mentioned weak point, thus a kind of anti-pulling shock insulation rubber bearing is provided, there is anti-pulling function, there is bigger vertical bearing capacity and all directions greater level displacement in plane simultaneously.
The technical scheme provided according to the present invention, anti-pulling shock insulation rubber bearing includes lower connecting plate, upper junction plate and bearing core body, it is characterized in that: linked into an integrated entity by bearing core body between lower connecting plate and upper junction plate.Lower connecting plate lower surface is provided with spring gathering sill, constitutes in four limit grooves of spring gathering sill and 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 is uniformly distributed with the center of lower connecting plate and upper junction plate for the center of circle.
Further, bearing core body includes that multiple steel plate layer and multiple rubber layer, multiple steel plate layer and the alternately laminated bonding of multiple rubber layer link into an integrated entity.
Further, it is bolted between bearing core body and lower connecting plate, upper junction plate.
Further, spring gathering sill is rectangle.
Further, the locking nut locked position that adjusting screw rod is connected by lower end.
Compared with the prior art the present invention has the advantage that
Present configuration is simple, compact, reasonable, easy for installation, safeguards simple, and service life is long；While playing overturn-preventing effect and horizontal seismic isolation effect, it is provided that certain horizontal rigidity, can more effectively reduce the earthquake destruction to building.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
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.
Detailed description of the invention
The embodiment combined in accompanying drawing is further described by the present invention below:
As shown in Figure 1 and 2, the invention mainly comprises lower connecting plate 1, upper junction plate 4 and bearing core body 5, linked into an integrated entity by bearing core body 5 between lower connecting plate 1 and upper junction plate 4, bearing core body 5 is uniformly distributed with the center of lower connecting plate 1 and upper junction plate 4 for the center of circle.It is bolted between described bearing core body 5 and lower connecting plate 1, upper junction plate 4.
Described bearing core body 5 includes that multiple steel plate layer and multiple rubber layer, multiple steel plate layer and the alternately laminated bonding of multiple rubber layer link into an integrated entity.
Lower connecting plate 1 lower surface is provided with the spring gathering sill 3 of rectangle, constitutes in four limit grooves 3.1 of spring gathering sill 3 and is respectively provided with a leaf spring 2.Spring gathering sill 3 is supplied to the transverse displacement space that leaf spring 2 compression produces, and guarantees that leaf spring 2 deformation position does not offsets simultaneously.
Leaf spring 2 center connects adjusting screw rod 7, and adjusting screw rod 7 upper end connects the cable wire 6 of the high intensity of anti-pulling, and cable wire 6 upper end is fixed on upper junction plate 4 through lower connecting plate 1.Locking nut 8 locked position that described adjusting screw rod 7 is connected by lower end.Pretightning force is regulated to cable wire 6, it is ensured that stress balance by adjusting adjusting screw rod 7.
The operation principle of the present invention is: when bearing produces horizontal displacement, cable wire also produces certain horizontal sextant angle displacement, drive leaf spring compresses, cable wire is made to extend, vertical displacement is made to be converted to horizontal displacement, making bearing can produce larger displacement in all directions and unrestricted, bearing core body produces horizontal displacement deformation to reduce infringement to building.
When producing tension in bearing, cable wire can drive leaf spring 2 to compress, certain pulling capacity is resisted and buffered to the stiffness by itself of leaf spring 2, when pulling up displacement and being larger than the pulling force that bearing core body can bear, cable wire will play and shift up restriction effect, play anti-pulling, the effect of overturn-preventing.
Present configuration is simple, compact, reasonable, easy for installation, safeguards simple, and service life is long；While playing overturn-preventing effect and horizontal seismic isolation effect, it is provided that certain horizontal rigidity, can more effectively reduce the earthquake destruction to building.
