Abstract
The invention relates to a novel bridge expansion joint structure, which includes: setting the right angle position of the bridge expansion joint structure shaped like right and left angles into a transitional slope, the section of the bridge expansion joint (1) is similarly Y-shaped structure with wide upper part and narrow lower part; nesting a rubber belt (2) in the expansion joint of the Y-shaped structure, the section of the rubber belt (2) is triangular belt shaped. The expansion joint structure is capable of slowing down the premature damage of the bridge expansion joint, prolonging the service life and ensuring the safe, smooth and express traffic; meanwhile, the expansion joint structure reduces the maintenance cost, saves the raw material and accelerates the construction.
Description
Technical field
The present invention relates to a kind of novel bridge expanded joint structure.Belong to the road and bridge engineering technical field.
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.Speedway, overhead road of city, various places different types of rridges build up in succession.Because vehicle flowrate, the speed of a motor vehicle, vehicular load improves constantly and bridge has been left over some minor issue in construction, makes the damage of bridge expanssion joint fastener very general.And that the damage of bridge expanssion joint fastener is jolted can cause vehicle ' the time is more than, and noise is disturbed the people, and the jumping car phenomenon of click click increases the weight of, and jeopardizes the safety of bridge and the application life of bridge, has increased the maintenance cost of bridge.So the stationarity of its durability, driving, passenger's comfortableness have caused the great attention of design and construction departments.
The adjacent both ends of the two beam bodies at traditional bridge expanssion joint place is
Structure is about to the bridge beam body end and is arranged to rectangular-shapedly, and this structure has increased shrinkage joint difficulty of construction and vulnerability.
Summary of the invention
The invention provides a kind of purpose and be to overcome above deficiency, a kind of novel bridge expanded joint structure that can improve the stationarity of durability and driving is provided.
The object of the present invention is achieved like this: a kind of novel bridge expanded joint structure is characterized in that described structure is with bridge expanssion joint
Transitional slope is arranged at the position, right angle of structure, make the bridge expanssion joint cross section be wide at the top and narrow at the bottom being similar to " Y " type structure, and in the shrinkage joint of this " Y " type structure, set a rubber strip, described rubber strip cross section is the triangle band shape, at last direct asphalt concrete on whole bridge floor again.Bridge expansion joint structure just can closely be linked to be an integral body with the drop table concrete on the bridge floor like this.
Rubber V-belt can play the variation of expanding with heat and contract with cold at the shrinkage joint that adjusting brings because of climate change; can greatly protect the bridge expanssion joint to prolong the application life of bridge again, avoided the contrast that bridge expanssion joint place cement and reinforcing bar rigidity hardness of building and the flexibility that bituminous concrete is built bring and draw current in jumping car phenomenon.
The present invention can slow down the premature failure phenomenon of bridge expanssion joint, increases the service life, and makes the vehicle energy safe, smooth-going, current fast, reduces maintenance cost simultaneously, saves material, and improves construction speed.
Description of drawings
Fig. 1 is the general structure schematic diagram of novel bridge expanded joint structure of the present invention.
The rubber strip outside drawing that Fig. 2 adopts for the present invention.
Among the figure: bridge expanssion joint 1, rubber strip 2, beam body 3, bituminous concrete 4, hole 2.1, small convex pillar 2.2.
The specific embodiment
Referring to Fig. 1, the novel bridge expanded joint structure that the present invention relates to, described structure is with bridge expanssion joint
Transitional slope is arranged at the position, right angle of structure, make bridge expanssion joint 1 cross section be wide at the top and narrow at the bottom being similar to " Y " type structure, and in the shrinkage joint of this " Y " type structure, set a rubber strip 2, described rubber strip 2 cross sections are the triangle band shape, at last direct asphalt concrete 4 on whole bridge floor again.Bridge expansion joint structure just can closely be linked to be an integral body with the drop table concrete on the bridge floor like this.
Referring to Fig. 2, some holes 2.1 are set, on the sidewall of described rubber strip 2 to increase the flexible diastolic dimension of rubber strip.The present invention can also be provided with some small convex pillars 2.2 on the surface of described rubber strip 2, to improve the adhesion of itself and bituminous concrete.
Claims (3)
1, a kind of novel bridge expanded joint structure is characterized in that described structure is with bridge expanssion joint
Transitional slope is arranged at the position, right angle of structure, makes bridge expanssion joint (1) cross section be wide at the top and narrow at the bottom being similar to " Y " type structure, and set a rubber strip (2) in the shrinkage joint of this " Y " type structure, and described rubber strip (2) cross section is the triangle band shape.
2, a kind of novel bridge expanded joint structure according to claim 1 is characterized in that being provided with some holes (2.1) on the sidewall of rubber strip (2).
3, a kind of novel bridge expanded joint structure according to claim 1 and 2 is characterized in that the surface of described rubber strip (2) is provided with some small convex pillars (2.2).
