Description
Technical field
The invention belongs to technical field of bridge engineering, relate to a kind of steel curved surface shock absorption and insulation rubber support, specially refer 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 the desired displacement of bridge span structure and rotation simultaneously.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 the spherical steel support of antidetonation type, lead core rubber support and high-damping rubber bearing.The spherical steel support of antidetonation type is by changing the structural form of 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 anti-fall beam 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.The high-damping rubber bearing is that common used materials such as the neoprene in the elastomeric material replacement General Purpose Rubber bearing with higher energy dissipation capacity of formulated, natural rubber are made.The characteristics of this bearing are that the hysteretic loop area is big, have the ability of bigger absorption seismic energy.At present domesticly main subtract, there is stressed big, the problem such as cost is high, easily come to nothing of anchor block in shock isolating pedestal and aseismatic bearing.
Summary of the invention
The invention provides a kind of steel curved surface shock absorption and insulation rubber support, use this bearing, can make each bridge pier resist seismic forces jointly, not only satisfy shockproof requirements, and cost low, do not come to nothing.
Technical scheme of the present invention 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:
The cylinder pendulum is the part cylinder, accommodates cambered surface at suitable bridge to cylinder and pastes mutually with lower support plate;
The ball pendulum is a segment, and ball is accommodated cambered surface and pasted mutually with lower support plate.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 block is set down, 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 pre-embedded bolt sleeve in the beam body by bolt; Four jiaos of pinner end face pre-embedded steel slabs link to each other with pre-embedded 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 invention and benefit are: use this bearing, can not distinguish fixed bearing and sliding support, subtract shock insulation by rubber layer and guarantee that each pier at any time bears seismic forces jointly, 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 bigger, by cylinder (ball) face solve vertical bridge to the big corner of Liang Dun, can satisfy by the rubber layer distortion if the direction across bridge corner is less, if the direction across bridge corner can satisfy by the ball face more greatly, solve the problem of coming to nothing of conventional laminated rubber bearing.This bearing cost is low, easy to assembly, be convenient to safeguard.
