Description
Technical field
The utility model relates to technical field of bridge construction, and in particular to a kind of interim expanded joint structure of bridge.
Background technique
Bridge expanssion joint is when having the influence such as external factor such as contraction of running car, temperature change, pontic to meet
The flexible requirement of bridge floor, usually at the expansion joint of two beam-ends joints or beam-ends and abutment joint setting one fixed width.
Expansion joint needs are vertical, are parallel in the both direction of bridge axes equal can generate is displaced free extension, and when vehicle crosses
Want steady when expansion joint, without convex jump and noise.The sequence of construction of bridge expanssion joint are as follows: pave and complete bituminous concrete upper layer
Afterwards, the bituminous concrete of expansion joint position is rejected, the fashioned iron at expansion joint and the embedded bar of bridge end is welded, finally existed
Casting concrete at the reserved location of expansion joint, can open to traffic after the completion of concrete curing.
Highway reconstruction, enlarging during, need frequently to carry out traffic lead change, the stage guarantor lead to, in order to guarantee most
The smooth traffic changed greatly, some sections need to just open section in pavement spread completion and pass through, construct to other sections after surface layer
After whole, then blocks section of not completing and construct；Therefore, section of not completing can not carry out expansion joint construction, but
It is the temporary traffic in order to ensure section of not completing, needs to be arranged before middle surface layer paves interim expansion joint, guarantees that road is handed over
Clear and coherent smooth, vehicle safety passes through.
Currently, existing interim expansion joint is that direct casting concrete and bridge deck pavement are flat in the step of bridge end
Together, surface layer in then paving on bridge deck pavement, then top plate is set in gap upper cover, the interim expansion joint of such structure exists such as
Lower disadvantage: bridge step is equipped with embedded bar with flexible seam welding, embedded bar is wrapped in when concreting in,
It is subsequent to cut concrete construct again lay permanent expansion joint when, embedded bar, which is laid in, to be caused to cut difficulty in concrete,
It is uneven directly to contact parting surface when causing to cut with bridge step for concrete simultaneously, in addition, cover board is only used at the both ends at expansion joint
Connection, so that the deformation buffer between bridge is unstable, the middle surface layer structure at frangible cover plate edge, service life is short.
Summary of the invention
In order to solve above-mentioned problem of the prior art, the utility model provides a kind of interim expanded joint structure of bridge, it is ensured that
Expansion joint can smoothly buffer when removing conveniently, while can guarantee bridge deformation, the integrality of surface layer in guarantee, improve and use the longevity
Life.
The purpose of this utility model can be realized by the following technical scheme: a kind of interim expanded joint structure of bridge, including
Building body, elastic cord breaker and filled layer are poured, the filled layer is located in the gap of two bridges engagement, and the building body of pouring is set respectively
It sets on the step of bridge, described pour is equipped with one layer of insulation blanket between building body and the step contact surface of bridge, the elasticity is slow

Layer is of same size.
Preferably, the filled layer is made with the transition pad of cystosepiment.
Preferably, the insulation blanket is made of malthoid.
The use principle of the utility model: installing filled layer between the gap of bridge, lays on bridge step and pours building body
Template, then carry out concreting, pour it is body formed after remove template, poured at two building body opposite side attach transition pad,
Then cover board is covered to be fastened and fixed with screw；Elastic cord breaker is poured between two transition pads, until elastic cord breaker and lid
Plate is concordant；Surface layer in being finally laid with, is cut into clip slot in middle surface layer, after middle surface layer acceptance(check), can temporarily pass through.
Resultant effect brought by the utility model includes:
1, the utility model simple structure is reasonable, easy to use, pours building body and is equipped with the contact surface of bridge step and is isolated
Felt avoids the concrete for pouring building body directly with step face contact, conveniently pours cutting for building body, while ensuring the complete of step surface
Property；Simultaneously the embedded bar in step be located in the groove for pouring building body not with pour building body and contact, it is ensured that pour internal clear,
Enable pour building body when smashing quickly, conveniently；Cover board is removably attachable to pour on building body upper surface；Transition pad is slow by elasticity
It rushes layer and is separated with building body is poured；To sum up, the above structure ensures that interim expansion joint can quickly remove, and accelerates the speed of construction in later period.
2, transition is lined with foam pad and is made, and has certain elasticity, expands in elastic cord breaker stress to two sides and upper end
When deformation, transition pad is compressed thinning, and certain deformation space is provided to elastic cord breaker, so that the change that elastic cord breaker is upward
Shape amount reduces, so that it is guaranteed that middle surface layer is smooth.
