Description

The isolation bridge bearing
Technical field
The utility model relates to a kind of shock isolating pedestal, relates in particular to a kind of bridge shock isolating pedestal.
Background technology
For promoting the shock resistance of bridge, between bridge supports and bridge floor, be provided with sliding shock isolating pedestal.Bridge supports is to be poured into undergroundly, and bridge floor generally is prefabricated, when building, is that bridge floor is stacked on pillar.Existing sliding shock isolating pedestal, slide surface is in the bottom of shock isolating pedestal main body.Like this, main body need be connected on the carrier of top.When being applied on the bridge, need the lifting precision very high, can when hoisting prefabricated bridge floor, increase difficulty.
Summary of the invention
The utility model provides a kind of bridge construction of being convenient at above problem, and can guarantee the isolation bridge bearing of isolating affection.
The technical solution of the utility model is: comprise the neoprene bearing that is made of rubber body, lamination steel plate, upper sealing plate and following shrouding, it comprises the screw and the lower connecting plate of reinforcement steel plate, tetrafluoro slide plate, corrosion resistant plate, upper junction plate, low-shearing force; Described upper junction plate area is greater than the area of described neoprene bearing upper surface, and fixedly connected with described upper sealing plate by securing member, go out the part of described neoprene bearing upper surface greatly at upper junction plate, be provided with screw connecting hole, the end face of upper junction plate is provided with the counterbore of height less than described tetrafluoro slide plate thickness; Described tetrafluoro slide plate is located in the described counterbore; Described corrosion resistant plate is fixedly connected on the bottom surface of described reinforcement steel plate, and the bottom surface of corrosion resistant plate contacts described tetrafluoro slide plate, makes described reinforcement steel plate and described upper junction plate leave the space between the correspondence position of the part that goes out described neoprene bearing upper surface greatly; The screw of described low-shearing force links to each other upper junction plate by described screw connecting hole with the reinforcement steel plate; Described lower connecting plate is fixedlyed connected with described shrouding down.
The screw of described low-shearing force be diameter less than 3mm, and described screw offers a circle groove in upper junction plate and position, reinforcement steel plate space, so that fracture.
The utility model is changed into top with slide surface, and adopts the screw of low-shearing force to connect, and can make rubber earthquake isolation support under the usual state and use.During work, the flexible main body in bottom is at first carried seismic surface wave, and when rubber earthquake isolation support is out of shape when excessive, the screw of the low-shearing force between junction plate and the reinforcement steel plate is broken, and can make the slide plate bearing and use, and satisfies the requirement of big displacement quantity.Play double protection.
