Abstract
A kind of transition slab at bridge head, be made up of attachment strap, hinge, steel plate, sub-attachment strap and pile, attachment strap forms stairstepping, when bypass face, the material on road surface can additionally arrange on sub-attachment strap with continuing, and road surface and attachment strap divide echelon transition, makes the stress of foundation settlement on attachment strap, have a slow process of falling, to reduce the difference that foundation settlement causes road surface and end of the bridge, bridge floor and road surface is avoided to occur step-like drop.
Description
Technical field
The present invention relates to a kind of highway bridge, specifically the rebound on a kind of bridge floor and road surface.
Background technology
The road surface of highway and bridge are because of the impact of ground gene power, and the stiffness difference of road and bridge, the differential settlement of unavoidable end of the bridge, the sedimentation difference phenomenon caused.The joining place of the highways and bridges especially newly built; owing to there is larger difference in height; often can run into and jump car phenomenon; sometimes then vehicle can soar into jumping up and fall heavyly; especially the stepped drop that occurs of bridge floor and road surface; this also exists huge hidden peril of accident concerning driving, is unfavorable for traffic safety.
Summary of the invention
In order to solving problem of vehicle bump at bridge head, the invention provides a kind of transition slab at bridge head, this attachment strap and bridge floor are provided with active joint, and the other end of attachment strap can sedimentation synchronous with road surface, thus avoids bridge floor and road surface to occur step-like drop, improves the safety factor of driving.
The present invention solves the technical measures that its technical problem takes, attachment strap is made up of steel concrete, steel plate is laid in the joint face of attachment strap and end of the bridge, one of steel plate is hinged with bridge floor, below the tip side of attachment strap and end of the bridge, open semicircle groove, this groove face steel plate wraps up, below corresponding half slot, pile squeezed into by ground, semicircle is made in pile upper end, and wrap up with steel plate, the arc head of pile just in time matches by dress with the half slot of attachment strap, stairstepping is made in the other end of attachment strap, the plane of lower one deck ladder drives deep-slotted chip breaker, sub-attachment strap is laid on deep-slotted chip breaker, protruding arc head is established in the position of the corresponding deep-slotted chip breaker of sub-attachment strap, this arc head matches with the deep-slotted chip breaker of sub-attachment strap and installs, the plate face of sub-attachment strap is lower than the plate face of attachment strap, horizontal straight trough is opened on sub-attachment strap, this groove can stop the superincumbent road surface of paving to glide, when paving, the material on road surface can be laid on above sub-attachment strap with continuing, road surface and attachment strap divide echelon transition, make the stress of foundation settlement on attachment strap, have a slow process of falling, to reduce the difference that foundation settlement causes road surface and end of the bridge, bridge floor and road surface is avoided to occur step-like drop, thus reach the object improving safe driving.
The invention has the beneficial effects as follows, improve the safety factor of driving, structure is simple.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is a kind of structural representation of transition slab at bridge head.
In figure, 1, attachment strap, 2, joint face, 3, steel plate, 4, hinge, 5, half slot, 6, pile, 7. deep-slotted chip breaker, 8. sub-attachment strap, 9. arc head, 10. straight trough.
Detailed description of the invention
In FIG, attachment strap 1 is made up of steel concrete, steel plate 3 is laid in the joint face 2 of attachment strap and end of the bridge, one of steel plate is connected with bridge floor hinge 4, below the tip side of attachment strap and end of the bridge, open semicircle groove 5, this groove face steel plate wraps up, below corresponding half slot, pile 6 squeezed into by ground, pile upper end is made arc and is wrapped up with steel plate, the arc head of pile just in time matches by dress with the half slot of attachment strap, stairstepping is made in the other end of attachment strap, the plane of lower one deck ladder drives deep-slotted chip breaker 7, sub-attachment strap 8 is laid on deep-slotted chip breaker, the arc head 9 of the position projection of the corresponding deep-slotted chip breaker of sub-attachment strap, this arc head matches with the deep-slotted chip breaker of sub-attachment strap and installs, the plate face of sub-attachment strap is lower than the plate face of attachment strap, horizontal straight trough 10 is opened on sub-attachment strap, this groove can stop the superincumbent road surface of paving to glide, when paving, the material on road surface can be laid on above sub-attachment strap with continuing, road surface and attachment strap divide echelon transition, make the stress of foundation settlement on attachment strap, have one to delay and fall process, to reduce the difference that foundation settlement causes road surface and end of the bridge.
