Close, extension spring hook is drawn in being vertically connected between plate.But the tensible rigidity and pressure of this tensile laminate rubber shock-insulation bracket
Although contracting rigidity compared to smaller, is also far longer than not influence rubber earthquake isolation support horizontal distortion, initial stiffness etc. basic
Improve the rigidity of the spring of bearing tensile capacity on the premise of mechanical property, major part pulling force is still during rubber earthquake isolation support tension
The spring in bearing or outside bearing is undertaken rather than be arranged on by rubber support itself, can not improve the tension energy of rubber earthquake isolation support
Power.
Utility model content
For the deficiency in the presence of the prior art, the utility model, which provides, a kind of can improve rubber earthquake isolation support
A kind of rubber earthquake isolation support rubber compression spring assembly of tensile capacity.
To achieve the above object, the utility model employs following technical solution：
A kind of bullet between rubber earthquake isolation support rubber compression spring assembly, including upper sealing plate, lower sealing plate, upper and lower sealing plate
Spring sleeve, spring pull rod, ball-type packing ring and spring fixing bolt, described seal up and down in steel plate are respectively arranged with concave spherical surface bolt
Hole；Fixed plate equipped with elastic component and the fixed elastic component, spring spool both ends and elastic component center in the spring spool

The utility model can significantly improve the anti-of rubber earthquake isolation support compared to the spring in traditional rubber earthquake isolation support
Drawing ability.The concave spherical surface bolt hole that ball-type packing ring seals steel plate relative to bearing up and down can be made each to rotation, make rubber vibration isolation branch
Rubber elasticity of compression component in seat meets horizontal direction respectively to displacement.Among the process of rubber earthquake isolation support horizontal direction displacement,
The horizontal direction that earthquake is effectively reduced with the elastic damping energy consumption effect that elastomer plays in rubber elasticity of compression component acts on；
When rubber earthquake isolation support reaches horizontal direction displacement limits, due to the effect of contraction of spring spool tube wall, elastic component no longer by after
Continuous compression, and limit shock isolating pedestal and continue horizontal direction displacement, so as to play horizontal direction drawing-resistant function.Erected in rubber earthquake isolation support
To during movement, the elastic damping energy consumption effect of elastomer can also be effectively reduced the vertical effect of shake；When elastomer is compressed
During to design limit, due to the effect of contraction of spring spool tube wall, elastomer no longer continues to compress, and then limits rubber vibration isolation
Bearing continues to move up and down, and allocates for using so as to play vertical tension.
Further, the elastic component compresses spring for the rubber of cylinder or polyurethane compresses spring, the table of cylinder
Face is corrugated in rule.
Corrugated spring has a larger big decrement, and the big decrement of corrugated spring and cylindrical rubber springs
Respectively meet each to horizontal displacement and vertical displacement of rubber earthquake isolation support to shear displacemant ability.
Compared with the prior art, the beneficial effects of the utility model are：Adhere to that elastic component reset capability is strong, durability
Well, the advantages of stable and reliable for performance, simple structure, easy to produce etc., big decrement and cylindrical rubber using corrugated spring
The each of glue spring meets each to horizontal displacement of rubber earthquake isolation support to shear displacemant ability, and utilizes elastomeric material bearing capacity
The anti-pulling ability of bearing is substantially improved in the advantages of big, has good practical value, the utility model can be additionally used in common rubber
The elasticity such as glue laminated shock isolation support, lead rubber laminated bearing, high-damping rubber shock isolating pedestal, ultra-high damping rubber shock isolating pedestal
The tension of body shock isolating pedestal dials structure, has good practical value, is widely used in building structure, bridge structure, road knot
The shock insulation protection of the civil engineering structures such as structure.
