Description
Technical field:
This utility model relates to a kind of bridge pad, is specifically related to a kind of antidetonation bridge pad.
Background technology:
Bridge is also the infrastructure in daily life, and the anti-seismic performance of bridge just becomes a part very important in Bridge Design. Take rationally effective earthquake resistant construction that usually aseismatic bearing is set between girder and bridge pier for bridge, bearing is a kind of structural vibration reduction element widely applied in engineering construction particularly science of bridge building, not only the weight transfer of central structure on bridge and other building structure to the substructure such as bridge pier, column, but also there is vibration damping and earthquake-resistant effect. Presently used has fixing pot type rubber support, movable pot rubber bearing etc., they resist seismic force mainly by the structural strength improving self, the intensity of the bridge up-down structure being connected with bearing must also be improved simultaneously, construction cost is made to be greatly increased, and existing bearing holds corrosion-vulnerable, affect its service life.
Summary of the invention:
The purpose of this utility model is to provide a kind of antidetonation bridge pad.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of antidetonation bridge pad, its composition includes: upper strata steel plate, described upper strata steel plate connects one group of shock insulation buffer substrate tablet, one group of described shock insulation buffer substrate tablet connects lower floor's steel plate, one group of described shock insulation buffer substrate tablet includes rubber buffer plate, sandwich clad steel, one group of described shock insulation buffer substrate tablet is between described upper strata steel plate and described lower floor's steel plate, the both sides of one group of described shock insulation buffer substrate tablet are respectively fixed with silicon steel plate, the opposite side of described silicon steel plate connects magnet exciting coil respectively, described magnet exciting coil top is separately installed with rubber fixed block, there is outside described upper strata steel plate upper protection coating, described lower floor's steel plate, the outside of described magnet exciting coil is respectively provided with lower protection coating.
Described antidetonation bridge pad, described rubber buffer plate and described sandwich clad steel are to be spaced.
Described antidetonation bridge pad, described upper strata steel plate, described lower floor's steel plate are respectively arranged with fixed bolt hole.
The beneficial effects of the utility model are:
The rubber buffer plate that this utility model adopts is to adopt magnetorheological elastomer material, consists of silicone rubber matrix and ferromagnetic particle, the anti-seismic performance of adjustment bridge pad that can be intelligent by magnetic rheology effect.
This utility model is when seismic wave is transmitted on ground, the both sides of the described one group shock insulation buffer substrate tablet adopted are respectively fixed with silicon steel plate, described silicon steel plate opposite side connects the energy that excitation coil structure can be transferred in structure respectively and is converted into the energy of other forms such as elastic potential energy, magnetic energy, heat energy, the conversion of shock insulation buffer substrate tablet group modulus of shearing is controlled, it is achieved the anti-seismic performance of bearing by the size of externally-applied magnetic field.
Having upper protection coating outside the steel plate of this utility model upper strata, described lower floor's steel plate, the outside of described magnet exciting coil are respectively provided with lower protection coating and can effectively improve the corrosion resistance of bearing, increase the service life of bearing.
The sum of rubber buffer plate described in the utility model and described sandwich clad steel is 7～15 layers.
Accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model.
