Background technology
Support at present the face of cylinder steel support that bridge uses, be utilize corrosion resistant plate that going up of steel support use between the pendulum and the bottom and polyfluortetraethylene plate as plane of rotation and slide plane to the material that rubs, adapt to and coordinate that the bridge end takes place vertically to rotate and dilatation.In order to improve the lotus ability of holding of polyfluortetraethylene plate, usually with in the steel tank of polyfluortetraethylene plate half build-in around the cylinder bottom, and this processing technology is quite complicated.It is earlier this workpiece to be divided into three part processing, cylinder body with the two ends band boss that processes, be connected with the cylinder body with the steel block along cylinder body tangential direction, form the boss on the cylinder body tangential direction, around the cylinder body, form steel tank thus, and with the polyfluortetraethylene plate build-in wherein, this complex procedures, difficulty of processing is big.On the other hand, the rotation of this face of cylinder bearing is just unidirectional, can only satisfy the bridge end and produce vertical rotational deformation-be the narrow bridge of folk prescription to rotational deformation.Under the wide bigger situation of bridge, bridge is under its deadweight or load action, and beam-ends two-way rotational deformation will take place comprises the vertical and horizontal rotational deformation, and bridge pad must adapt to the two-way rotational deformation of beam.
Summary of the invention
The purpose of this utility model is to provide a kind of cylinder bridge pad of two-way rotation, the two-way rotational deformation that comprises bridge end vertical and horizontal in order to adaptation, between the last pendulum and the bottom, use copper coin to replace polyfluortetraethylene plate simultaneously, overcome the difficulty of processing of build-in polyfluortetraethylene plate, it is simple in structure, bearing capacity is big, improves application life.
The purpose of this utility model is achieved in that
A kind of cylinder bridge pad of two-way rotation, comprise put 1 on the face of cylinder, the cylinder bottom 4 and base plate 8 form, it is characterized in that on the face of cylinder pendulum 1 below be shaped as the face of cylinder, the top type shape of the cylinder bottom 4 also is the face of cylinder, corrosion resistant plate 2 is equipped with in the bottom of pendulum 1 on the face of cylinder, on the top of the cylinder bottom 4 copper coin 3 being housed, is face of cylinder sliding-contact between corrosion resistant plate 2 and the copper coin 3; Between the cylinder bottom 4 and base plate 8, be provided with simultaneously rubber mat plate 5, polyfluortetraethylene plate 6 and corrosion resistant plate 7, it below the cylinder bottom 4 flanged groove around, bottom land is the plane, rubber mat plate 5 embeds in this groove, the polyfluortetraethylene plate 6 of half build-in in the cylinder bottom 4 grooves arranged below rubber mat plate 5, be welded with corrosion resistant plate 7 on the base plate 8, contact for planar slide between polyfluortetraethylene plate 6 and the corrosion resistant plate 7.
The cylinder bridge pad of two-way rotation of the present utility model, it be utilize to go up pendulum 1 face of cylinder down corrosion resistant plate 2 and the bottom 4 faces of cylinder on cylinder slip between the copper coin 3 satisfy vertical rotational deformation of bridge end, also utilize the lateral rotation of the inhomogeneous compression adaptation bridge end of rubber mat plate 5, utilize simultaneously the rotation and the dilatation of the planar slide coordination bridge end between polyfluortetraethylene plate 6 and the corrosion resistant plate 7 again, be applicable to a kind of novel bridge bearing of bridge and viaduct beam-ends.
