Abstract
The utility model discloses a kind of basin-shaped seating of antidetonation, belong to basin type support for bridges field, the technical scheme adopted is, a kind of basin-shaped seating of antidetonation, comprise upper bracket plate, pot base and the PTFE plate set gradually between upper bracket plate and pot base, basin core, frictional damping pair and pressure-bearing rubber tile from top to bottom, outside basin core, be provided with the barrier block being fixed on upper bracket plate soffit by screw, be fixed with block rubber in the inner side of barrier block.The utility model has the advantages that, (1) pot bearing provided by the utility model forms multi-buffer damping when shaking, and all has defencive function to bridge and bearing; (2) earthquake isolation mechanism structure is simple, installs and convenient disassembly.
Description
Technical field
The utility model belongs to basin type support for bridges field, is specifically related to a kind of basin-shaped seating of antidetonation.
Background technology
Along with the development of transportation and the raising of construction standard, bearing not only plays a supportive role in bridge and engineering, more should have damping, antidetonation, resist displacement effect.At present, bearing for bridge generally includes pot base, basin core and basin lid, PTFE plate is set between basin core and basin lid, pressure-bearing rubber tile is set between pot base and basin core, but when there is earthquake or by stronger external force, resist the vibrations of horizontal direction between basin core and basin lid with adaptivity adjustment of displacement, its anti seismic efficiency limitation is very large.
Summary of the invention
For solving the problem, the utility model provides a kind of basin-shaped seating of antidetonation, by easy installation and removal on pot bearing, the mechanism with shock insulation, shock-absorbing function, improves the ability of pot bearing opposing high strength vibrations.
The technical solution adopted in the utility model is, a kind of basin-shaped seating of antidetonation, comprise upper bracket plate, pot base and the PTFE plate set gradually between upper bracket plate and pot base, basin core, frictional damping pair and pressure-bearing rubber tile from top to bottom, outside basin core, be provided with the barrier block being fixed on upper bracket plate soffit by screw, be fixed with block rubber in the inner side of barrier block.
In technique scheme, barrier block is fixedly mounted on upper bracket plate soffit by screw, to be positioned at outside basin core and to have gap with basin core, between block rubber is fixed on outside barrier block and basin core, forms earthquake isolation mechanism.When upper bracket plate chance is shaken strongly, relative displacement is produced with basin core, now first extrude block rubber, by the extruding consumed energy gradually of block rubber, concussion strengthens further when exceeding the deformation limit of block rubber, the stressed and damping of screw, when concussion active force is large again, screw is cut off, and the further damping of consumed energy, is after this delivered to pot base and pier by concussion more simultaneously.Being provided with frictional damping pair between basin core and pressure-bearing rubber tile, making active force further damping when being delivered to pier, this design forming vibrations multi-buffer, reduces the damage because great force causes bridge and bearing.
The beneficial effects of the utility model are: (1) pot bearing provided by the utility model forms multi-buffer damping when shaking, and all has defencive function to bridge and bearing; (2) earthquake isolation mechanism structure is simple, installs and convenient disassembly.
Below in conjunction with accompanying drawing, the utility model is described in detail.

Detailed description of the invention
As shown in Figure 1, basin-shaped seating of antidetonation provided by the utility model, comprise upper bracket plate 1, pot base 4 and be successively set on PTFE plate 2, basin core 3, frictional damping pair 6 and the pressure-bearing rubber tile 5 between upper bracket plate 1 and pot base 4 from top to bottom, outside basin core 3, be provided with the barrier block 8 being fixed on upper bracket plate 1 soffit by screw 11, be fixed with block rubber 9 in the inner side of barrier block 8.
Barrier block 8 is fixedly mounted on upper bracket plate 1 soffit by screw 11, to be positioned at outside basin core 3 and to have gap with basin core 3, between block rubber 9 is fixed on outside barrier block 8 and basin core 3, forms earthquake isolation mechanism.When upper bracket plate 1 meet strongly shake time, relative displacement is produced with basin core 3, now first extrude block rubber 9, by the extruding consumed energy gradually of block rubber 9, concussion strengthens further when exceeding the deformation limit of block rubber 9, the stressed and damping of screw 11, when concussion active force is large again, screw 11 is cut off, and the further damping of consumed energy, is after this delivered to pot base 4 and pier by concussion more simultaneously.Being provided with frictional damping pair 6 between basin core 3 and pressure-bearing rubber tile 5, making active force further damping when being delivered to pier, this design forming vibrations multi-buffer, reduces the damage because great force causes bridge and bearing.
Described barrier block 8 is T-shaped or L shape, and barrier block 8 is fixedly mounted on upper bracket plate 1 soffit by screw 11.Described block rubber 9 is fixed by positioning bolt 12 and barrier block 8, and described positioning bolt 12 is spacing to be also connected with setscrew nut with barrier block 8 through block rubber 9 in the counterbore of baffle plate 10.Positioning bolt 12 surface is shiny surface, can move freely after barrier block 8, block rubber 9, baffle plate 10 are stressed on bolt 12.
With gap outside described basin core 3 and between pot base 4, in gap, be provided with damped ring 7, in the transmittance process of basin core 3 and pot base 4, buffering can be formed further, to alleviate the infringement of vibrations to bridge to horizontal direction active force.
