Description
Technical field
The utility model belongs to the bridge pad technical field, relates in particular to a kind of highway bridge elastic buffer pot rubber bearing.
Background technology
The function of bridge pad is that the bearing reaction with superstructure is delivered to Bridge Pier and guarantees that structure can Free Transform under the factor effects such as automobile load, variations in temperature, concrete shrinkage and creep.The bearing of beam bridge generally is divided into two kinds of fixed and movable bearings.Usually in placement process, the lateral force of fixed bearing and one-way movable support meeting shared bridge because there is the guiding clearance in one-way movable support, often only has the fixed bearing lateral force resisting, thereby exist anchor block stressed excessive, the irrational situation of bridge system bearing distribution.
The utility model content
The technical problems to be solved in the utility model just is to provide a kind of more rational highway bridge elastic buffer of bridge force-bearing pot rubber bearing that makes.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise upper bracket plate, middle steel liner plate, rubber tile, end basin, be provided with pressing plate, combined steel plate spring and U-shaped plate between described upper bracket plate and middle steel liner plate, U-shaped plate is connected with limiting plate by alignment pin, and limiting plate is connected with middle steel liner plate by fastening bolt.
Its additional technical feature is: the two ends of described pressing plate are provided with boss, and U-shaped plate is provided with the gathering sill that is complementary with boss; Be provided with the sliding friction pair that corrosion resistant plate and SF-1 composite plate consist of between described upper bracket plate and pressing plate.
Highway bridge elastic buffer pot rubber bearing provided by the utility model is provided with the elastic mechanism module that pressing plate, combined steel plate spring and U-shaped plate consist of between upper bracket plate and middle steel liner plate.During the bearing assembling, rubber tile, middle steel liner plate and copper sealing ring are arranged in end basin.Then pressing plate, combined steel plate spring and U-shaped plate are placed successively, by hold down gag, pressing plate is pressed into place, put into long alignment pin and pass limiting plate, U-shaped plate and pressing plate and carry out spacing to pressing plate.Thereafter with fastening bolt, limiting plate and middle steel liner plate are fixed, then installed support plate, the wearing plate of inlaying on the corrosion resistant plate that makes upper bracket plate bottom surface and middle steel liner plate coordinates, and the corrosion resistant plate of upper bracket plate side coordinates with the polyfluortetraethylene plate on pressing plate.Extract at last long alignment pin out, the alignment pin of changing appropriate length only passes limiting plate and U-shaped plate.
A kind of highway bridge elastic buffer pot rubber bearing provided by the utility model in use, when the beam body is subject to lateral force, be delivered to pressing plate by the upper bracket plate, the pressing plate that studs with the SF-1 composite plate moves ahead along the gathering sill of boss, be that pressing plate passes through and is connected the connection of plate key slot type, pressure is passed to the combined steel plate spring uniformly.Under the effect of pressure, the combined steel plate spring occurs bending and deformation, certain resistance of deformation is provided simultaneously, lateral force resisting, then the combined steel plate spring conducts to U-shaped plate with power, and U-shaped plate two ends are fixed by alignment pin, steel liner plate in the middle of U-shaped plate conducts to power again, middle steel liner plate is embedded in end basin, and lateral force is passed to pier the most at last.In the transmittance process of lateral force, because bearing has all increased the elastic mechanism module that pressing plate, combined steel plate spring and U-shaped plate consist of, can alleviate the impact of lateral force, and can make fixed bearing and freely movable bearing lateral force resisting simultaneously, avoided conventional bearing in use, the stressed excessive situation of fixed bearing makes bridge system bearing distribution more reasonable.In the use procedure of bearing, under damage, may cause the fatigue failure of combined steel plate spring, in case such situation occurs, and can first limiting plate be pulled down, and takes out U-shaped plate and pressing plate, then just the combined steel plate spring that destroys can be taken out, again intact combined steel plate spring is put into, by hold down gag, pressing plate is pressed into place, put into long alignment pin spacing.After installation, long alignment pin is replaced by the alignment pin of normal operation, make pressing plate movable freely at direction across bridge.
A kind of highway bridge elastic buffer pot rubber bearing provided by the utility model has changed that the traditional axle beam support is fixed, unidirectional and multidirectional mode classification, this bearing only needs fixed and movable two kinds of structural shapes, just can satisfy whole bridge system carrying, the requirement of displacement and corner.This bearing is provided with the elastic mechanism module, can realize bridge pier shared bridge lateral force, has optimized the mechanical structure of bridge system.On the structure design of bearing, taken into full account the elastic mechanism module if there is fatigue failure, the convertibility of this structure.
