Technical field
The utility model belongs to technical field of bridge engineering, relates to a kind of steel curved surface shock absorption and insulation rubber support, specially refers to the shock absorption and insulation rubber support of a kind of steel column face or steel ball face.
Background technology
Bridge pad is arranged between the superstructure and pier of bridge, and its effect is that the various load counter-forces on the bridge span structure are delivered on the pier, guarantees simultaneously the desired displacement of bridge span structure and rotation.Bearing is divided into common bearing and aseismatic bearing.Aseismatic bearing is by the shockproof requirements design, can resist seismic forces.At present domesticly main subtract, the type of shock isolating pedestal and aseismatic bearing has Anti-seismic spherical steel support, lead core rubber support and high-damp rubber support.The Anti-seismic spherical steel support is by changing the structural form of upper lower support plate, guaranteeing to satisfy outside the conventional bearing requirement, and the cyclic reverse loading in the time of can also bearing earthquake and satisfy the girder falling requirement.Lead core rubber support is to insert lead for retractable pencil in the multilayer rubber bearing, when multilayer rubber produces shear strain, utilizes the plastic strain of lead for retractable pencil to absorb energy.High-damp rubber support is that having than common used materials such as the neoprene in the elastomeric material replacement General Purpose Rubber bearing of highly energy-consuming ability, natural rubbers of formulated is made.The characteristics of this bearing are that hysteretic loop is large, have the ability of larger absorption seismic energy.At present domesticly main subtract, there is stressed large, the problem such as cost is high, easily come to nothing of anchor block in shock isolating pedestal and aseismatic bearing.
The utility model content
The utility model provides a kind of steel curved surface shock absorption and insulation rubber support, uses this bearing, can make each bridge pier jointly resist seismic forces, not only satisfies shockproof requirements, and cost low, do not come to nothing.
The technical solution of the utility model is:
A kind of steel curved surface shock absorption and insulation rubber support is the shock absorption and insulation rubber support of a kind of steel column face or steel ball face, comprises upper bracket plate, cylinder (ball) pendulum, lower support plate, rubber, interior steel plate.Upper bracket plate and lower support plate all are rectangular slabs, and four limits of upper bracket plate are cast with four side bumper pieces; Lower support plate is basin shape, is embedded in the vertical block of upper bracket plate to lower support plate along bridge, and the horizontal block alignment of direction across bridge lower support plate projection and bearing upper plate, there is the slit centre.
Between upper bracket plate and lower support plate, place cylinder pendulum or ball pendulum:
Cylinder pendulum is the part cylinder, is accommodating cambered surface and lower support plate is affixed along bridge to cylinder;
The ball pendulum is a segment, and cambered surface accommodated by ball and lower support plate is affixed.Between the upper surface of cylinder (ball) pendulum and the upper bracket plate corrosion resistant plate and polyfluortetraethylene plate are set, between soffit and undersetting steel, the plate corrosion resistant plate and polyfluortetraethylene plate are set also.
The lower support plate below arranges laminated rubber bearing, and laminated rubber bearing comprises rubber and interior steel plate.Around lower support plate block is set, is connected with lower support plate to bolt by level, laminated rubber bearing is embedded in the block.Around the laminated rubber bearing bottom surface lower block is set, links to each other with pinner end face pre-embedded steel slab by vertical bolt.
Four jiaos of upper bracket plate link to each other with built-in bolt sleeve in the beam body by bolt; Four jiaos of pinner end face pre-embedded steel slabs link to each other with built-in bolt sleeve in the pinner by bolt.
The arc dust cover is set around between upper bracket plate and the lower steel plate, links to each other by bolt.
Upper bracket plate, lower support plate adopt cast steel, and other part steel adopt Q235 or Q345 material.
Effect of the present utility model and benefit are: use this bearing, can not distinguish fixed bearing and sliding support, subtract shock insulation by rubber layer and guarantee at any time shared seismic forces of each pier, solve spherical steel support mainly by the anchor block antidetonation, the stressed king-sized problem of anchor block can significantly reduce the construction costs of substructure; Since along bridge to corner larger, by cylinder (ball) face solve vertical bridge to the large corner of Liang Dun, if the direction across bridge corner to satisfy by the rubber layer distortion, if the direction across bridge corner can satisfy by Surface of Sphere more greatly, solves the problem of coming to nothing of conventional laminated rubber bearing than I.This bearing cost is low, easy to assembly, be convenient to safeguard.
