Description
Technical field
This utility model relates to bridge construction field, is specifically related to a kind of spring damping formula bridge expansion joint structure.
Background technology
Along with the fast development of urban construction, the development of all kinds of means of transportation is advanced by leaps and bounds.All kinds of different types of rridges such as highway, overhead road of city build up in succession.Due to vehicle flow, speed, car load improves constantly and some minor issue left over by bridge in construction, and the damage making bridge expanssion joint fastener is very general.And the damage of bridge expanssion joint fastener can cause vehicle to jolt incessantly when travelling, noise disturbs residents, and the jumping car phenomenon of click click increases the weight of, and jeopardizes the safety of bridge and the service life of bridge, increases the maintenance cost of bridge.So the durability degree of bridge, driving stationarity, passenger comfortableness caused the great attention of design and construction department.
Therefore; for solving problem above; need a kind of can regulate because climate change brings the change expanded with heat and contract with cold at expansion joint; bridge expanssion joint can be protected again greatly and extend bridge service life, it is to avoid bridge expanssion joint place Colophonium tilts or depression causes the spring damping formula bridge expansion joint structure of jumping car phenomenon in driving conditions.
Utility model content
The purpose of this utility model is to provide and a kind of can regulate because climate change brings the change expanded with heat and contract with cold at expansion joint; bridge expanssion joint can be protected again greatly and extend bridge service life, it is to avoid bridge expanssion joint place Colophonium tilts or depression causes the spring damping formula bridge expansion joint structure of jumping car phenomenon in driving conditions.
Spring damping formula bridge expansion joint structure of the present utility model, including adjacent two beam body, described beam body opposing sidewalls tilts to make to form up-narrow and down-wide inverted trapezoidal seam between beam body；Being provided with the trapezoidal block rubber coordinated with beam body sidewall contact in described inverted trapezoidal seam, described beam body and trapezoidal block rubber top are coated with bitumen layer, are provided with the spring-damping element for supporting trapezoidal block rubber between described two beam body；Described spring-damping element includes bullet and peaks at the spring between beam body and trapezoidal block rubber bottom surface and the antivibrator being arranged in spring；
Further, the sidewall of described beam body is provided with support platform, and described spring-damping element is installed on described support platform；
Further, the sidewall that described trapezoidal block rubber contacts with beam body is coated with wear-resisting sliding layer；
Further, the hydraulic cylinder of described antivibrator is fixed on support platform, and the piston rod of antivibrator peaks at bottom trapezoidal block rubber.
nullThe beneficial effects of the utility model are: spring damping formula bridge expansion joint structure of the present utility model，Trapezium structure seam wide at the top and narrow at the bottom is formed between two adjacent beam body，Trapezoidal block rubber can move up and down thus changing the Support Position to bitumen layer in ladder shaped connecting seam，When seam between beam body narrows，Trapezoidal block rubber is downward sliding under the pressure effect of beam body side wall inclined plane，Thus reducing the bearing height to bitumen layer，Avoid bitumen layer protruding，When seam between beam beam body broadens，Trapezoidal block rubber is upwards sliding under the action of the spring，Improve the Support Position to bitumen layer，Avoid bitumen layer concave downward，Finally avoid jumping car phenomenon in bridge floor driving conditions，Simultaneously，Owing to being additionally provided with antivibrator between beam body and inverted trapezoidal block rubber，Therefore，Up-down vibration will not be there is in block rubber，Ensure the gentle support to bitumen layer.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model；As it can be seen, the spring 2 damp type bridge expansion joint structure of the present embodiment, including adjacent two beam body 1, described beam body 1 opposing sidewalls tilts to make to be formed between beam body 1 up-narrow and down-wide ladder shaped connecting seam；Being provided with the trapezoidal block rubber 4 coordinated with beam body 1 sidewall contact in described inverted trapezoidal seam, described beam body 1 is coated with bitumen layer 5 with trapezoidal block rubber 4 top, is provided with spring 2 damping unit for supporting trapezoidal block rubber 4 between described two beam body 1；Described spring 2 damping unit includes bullet and peaks at the spring 2 between beam body 1 and trapezoidal block rubber 4 bottom surface and the antivibrator 3 being arranged in spring 2；Trapezoidal block rubber 4 can move up and down thus changing the Support Position to bitumen layer 5 in ladder shaped connecting seam, when seam between beam body 1 narrows, trapezoidal block rubber 4 is downward sliding under the pressure effect of beam body 1 side wall inclined plane, thus reducing the bearing height to bitumen layer 5, avoid bitumen layer 5 protruding, when seam between beam beam body 1 broadens, trapezoidal block rubber 4 is upwards sliding under the effect of spring 2, improve the Support Position to bitumen layer 5, avoid bitumen layer 5 concave downward, finally avoid jumping car phenomenon in bridge floor driving conditions, simultaneously, owing to being additionally provided with antivibrator 3 between beam body 1 and inverted trapezoidal block rubber 4, therefore, up-down vibration will not be there is in block rubber 4, ensure the gentle support to bitumen layer 5.
In the present embodiment, the sidewall of described beam body 1 is provided with support platform, described spring 2 damping unit is installed on described support platform, supports platform and adopts concrete integral type build molding and stretch out in the horizontal direction from beam body 1 sidewall with beam body 1, it is ensured that the bonding strength between itself and beam body 1.
In the present embodiment, the sidewall that described trapezoidal block rubber 4 contacts with beam body 1 is coated with wear-resisting sliding layer 6, this wear-resisting sliding layer 6 can adopt slip fibre board to be pasted on block rubber 4 sidewall, wear-resisting sliding layer 6 is conducive to reducing the force of sliding friction between block rubber 4 and beam body 1, simultaneously, it is to avoid block rubber 4 excessive wear.
In the present embodiment, the hydraulic cylinder of described antivibrator 3 is fixed on support platform, the piston rod of antivibrator 3 peaks at bottom trapezoidal block rubber 4, the hydraulic cylinder of antivibrator 3 can adopt the securing members such as crab-bolt to be fixed on support platform, avoid unstability after its pressurized, for avoiding block rubber 4 bottom surface compressive deformation, a metal profile, spring 2 and antivibrator 3 can be set in its bottom surface and directly act on gripper shoe bottom surface.
What finally illustrate is, above example is only in order to illustrate the technical solution of the utility model and unrestricted, although this utility model being described in detail with reference to preferred embodiment, it will be understood by those within the art that, the technical solution of the utility model can be modified or equivalent replacement, without deviating from objective and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
