Description
Technical field
The invention belongs to the bridge technology field, relate to a kind of vibration-insulation damping supporting seat that subtracts that is used for bridge concretely.
Background technology
At present, the bearing that is used for bridge generally includes upper bracket plate 8, lower support plate 1, pressure-bearing rubber tile 2 and middle steel liner plate 3, steel liner plate 3 and pressure-bearing rubber tile 2 are arranged between upper bracket plate 8 and the lower support plate 1 in the middle of described, according to function require have horizontal relative displacement trend between upper bracket plate 8 and the middle steel liner plate 3, be adjusted by the self adaptation under external force or the vibration situation in order to adapt to bridge, carry out spacing by the edge-on wall of upper bracket plate 8 as shown in Figure 3 to middle steel liner plate 3 simultaneously, in when, earthquake taking place or be subjected to strong external force when, upper bracket plate 8 and middle steel liner plate 3 in this structure opposing earthquake horizontal force, all be to adopt hard anti-mode between middle steel liner plate 3 and the lower support plate 1, need be when improving intensity by increasing the intensity of lower support plate 1 basin ring and upper bracket plate 8 edge-on walls for meeting design requirement, or the tonnage that improves beam body and pier satisfies the requirement of horizontal force, so just increased cost.And also unusual trouble of the replacing of bearing, need with jack beam all jack-up come integral replacing.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, be skillfully constructed, anti seismic efficiency is good and the vibration-insulation damping supporting seat that subtracts that is used for bridge of antidetonation assembly easy installation and removal.
Technical scheme of the present invention is as follows:
A kind of vibration-insulation damping supporting seat that subtracts that is used for bridge, comprise upper bracket plate, lower support plate, pressure-bearing rubber tile and middle steel liner plate, steel liner plate and pressure-bearing rubber tile are arranged between upper bracket plate and the lower support plate in the middle of described, outside described middle steel liner plate, be fixed with and subtract the shock insulation block, this subtract the shock insulation block and described in the middle of be provided with damping rubber and shearing-resistance blocks between the steel liner plate outside, described damping rubber subtracts in the groove that forms between shock insulation block and the shearing-resistance blocks described, wherein said shearing-resistance blocks and subtract and be plugged with shear-pin between the shock insulation block and be bolted to connection.
Adopt said structure can realize following function:
1, during non-earthquake this structure can play a part normal fixing in the middle of steel liner plate, horizontal force through the upper bracket plate, subtract the connecting bolt between shock insulation block and the shearing-resistance blocks, middle steel liner plate is delivered to lower support plate, and then be delivered on the pier;
2, during earthquake, when horizontal force surpassed design load, shearing-resistance blocks and the shear-pin that subtracts between the shock insulation block will be cut off, and constraint is released, and beam body drive bearing superstructure moves horizontally, squeezed air-damping rubber, and the crimp by damping rubber is consumed energy gradually.In this process, cutting off of shear-pin can absorb energy.So just, isolate and weaken the percussion of earthquake horizontal force beam body, pier and a seat body;
3, this structure has also played anti-fall beam action simultaneously, retrain the displacement of upper bracket plate when the earthquake by the thickness of adjusting damping rubber, to prevent beam body generation over-large displacement and the beam situation that falls by subtracting being moved further of shock insulation stop limits beam body after reaching the design displacement;
4, the replacing of this structure and safeguard the convenience all compare only need be laid down and connects the upper bracket plate and subtract connecting bolt between the vibration-insulation damping device, repairs or change to get final product.
5, the connecting bolt that subtracts between shock insulation block and the shearing-resistance blocks can play the counteracting moment of flexure that middle steel liner plate produces shearing-resistance blocks under the effect of horizontal force.But also play with described shearing-resistance blocks and subtract the identical purpose of shear-pin between the shock insulation block, when being cut off, further absorb energy, reduce the percussion of earthquake horizontal force to beam body, pier and a seat body.
The described shock insulation block soffit that subtracts is provided with pressing plate.
Pressing plate is to subtracting the effect that shock insulation block, shearing-resistance blocks and damping rubber play lower limit, can also reach endergonic effect simultaneously when making pressing plate produce gradually yield deformation because of the earthquake horizontal force when.
Described upper bracket plate is provided with " U " shape groove, should " U " shape groove fixes with the described protuberance that subtracts the setting of the shock insulation block upper end merga pass connecting bolt that matches.
By upper bracket plate " U " shape groove with subtract the design that shock insulation block upper end protuberance matches, can play on the upper bracket plate subtracting the horizontal position-limiting action of shock insulation block, avoid connecting bolt to be subjected to the shearing force fracture.
Beneficial effect: the present invention is simple in structure, be skillfully constructed, anti seismic efficiency is good and the easy installation and removal of antidetonation assembly.
