Description
Technical field
The utility model belongs to technical field of bridge, more particularly to a kind of applied to bridges such as steel bridge and concrete bridges
Antidetonation girder falling laminated rubber bearing.
Background technology
In Bridge Design, bearing passes to substructure as critical piece, its load that carry bridge top, and
And the need for meeting the rotation and displacement of superstructure.Bearing is divided into spherical bearing, pot bearing and sheet-type support, sheet-type support
It is to be formed by multilayer rubber plate and sheet metal vulcanization, stickup, sheet-type support is arranged between beam body and pier, can be by superstructure
Counter-force pass to pier, be adapted to beam-ends vertical rotating, there is horizontal shear deformability, the water of superstructure can be met
Prosposition is moved.In practical application, when coming earthquake, when beam body is in the sphere of action of sheet-type support, the protective effect to bridge
Substantially, but when super anticipated movement occurs for bridge beam body, easily cause beam body to take a seat or even fall beam, serious harm is caused to bridge.Plate
Formula bearing lacks girder falling function so that the performance of sheet-type support is influenceed by certain.
Utility model content
The technical problems to be solved in the utility model is just to provide a kind of anti-fall beam and slab type of the antidetonation for possessing girder falling function
Rubber support.
In order to solve the above technical problems, the technical solution adopted in the utility model is：Include the bullet of built-in multilayer sheet metal
It is provided with above property body, the elastomer below upper plate, elastomer and is provided with lower plate, is provided between upper plate and lower plate anti-
Arm-tie, tension plate bottom is connected by bolt with lower plate, and upper plate is provided with L-type handle, and tension plate top is provided with draws with L-type
The groove of palmistry matching.
Its additional technical feature is：Described lower plate is provided with the shear key matched with elastomer phase；
Being provided at both ends with for the L-type handle is spacing.
Upper plate is provided with above antidetonation girder falling laminated rubber bearing provided by the utility model, elastomer, elasticity
Lower plate is provided with below body.During installation, upper plate is fixed with beam body, and lower plate is fixed with pier, due to being set between upper plate and lower plate
It is equipped with tension plate so that upper plate and lower plate are connected as a single entity.The counter-force of superstructure can be passed to pier by bearing, be adapted to beam
Vertical rotating is held, there is horizontal shear deformability, the horizontal displacement of superstructure can be met, and with girder falling function.It is anti-
Arm-tie bottom is connected by bolt with lower plate, and upper plate is provided with L-type handle, and tension plate top is provided with and L-type handle phase
The groove matched somebody with somebody so that tension plate is connected fast and simple with lower plate, upper plate, good integrity.Lower plate is provided with to be matched with elastomer phase
Shear key, when not less than lateral displacement setting value, shear key stop elastomer.Simultaneously as upper plate spacing, Yi Jikang
Arm-tie is held to upper plate, prevents bearing from disintegrating, and effectively prevents that beam body from taking a seat or even falling beam.What L-type was shaken hands is provided at both ends with limit
Position, plays limiting displacement.
Antidetonation girder falling laminated rubber bearing provided by the utility model, is the narrow range base in laminated rubber bearing
Bridge restrainer etc. is designed on plinth, taking increases necessary and simple steel assembling fittings into the bearing with function of seismic resistance.
The Aseismic Design construction cost such as bridge restrainer is transferred in the cost of bearing, it is achieved thereby that simplifying design with applying
Work.It is a kind of multi-functional bearing suitable for earthquake-resistant structure thing, using the safety of flexible protective building, high intensity and with height
The aseismatic bearing of endurance quality.Possess the inclination occurred when the inclination or installation that produce structure and utilize inner rubber or rubber
The peculiar function that layer is absorbed.Its compact conformation, sets easy.
