Description
Technical Field
The invention relates to the technical field of bridge engineering, in particular to a reinforcing device for a hinge joint of a bridge hinge joint.
Background
Hinge seam before concreting, need seal the board seam between the hollow slab earlier, prevent that concreting from revealing, current hinge seam seal structure, for example: in the middle of the patent that application number is 201410173720.8, need special bar planting hole and U type muscle, come the lower extreme opening of sealed board seam, seal the board seam pouring sealing material, make its structure complicated, sealed cost is higher.
The original hinge joint treatment method is characterized in that hinge joint diseases are generated by adjusting a hinge joint structure, increasing the thickness of a bridge deck pavement layer and adopting a traditional repair material, the adjustment of the hinge joint structure has a poor treatment effect on the hinge joint diseases, the thickness of the bridge deck pavement layer is increased greatly, the construction cost is increased, and the existing bridge hinge joint treatment material mainly comprises an inorganic repair material mainly based on cement and an organic repair material mainly based on polymer concrete and epoxy resin. The problems of the cement-based inorganic repair materials are as follows: the interface transition area between the repairing material and the base material is relatively weak, the repairing material is easy to fall off to cause repairing failure, and cracks are easy to generate under the condition of large temperature difference to influence the integrity of the hinge joint. The problems of the organic repairing materials mainly comprising polymer concrete and epoxy resin are as follows: high cost, easy ageing, big performance difference with old concrete, no fire resistance and poor durability.
The original treatment method is adopted to generate larger temperature cracks in a large temperature difference area, once the cracks appear in the hinge joint, the cracks are damaged and accelerated under the condition of long-term dynamic load, the bridge deck is damaged by light people, the plate joint has water leakage, and freeze thawing circulation forms icicles under the winter condition to cause safety accidents, such as long-term damage of the hinge joint, stress on a single plate of a beam plate and fracture of the beam plate; and long-time traffic sealing is needed, which brings great inconvenience to people.
Disclosure of Invention
According to the reinforcing structure for the bridge hinge joint, the reinforcing device is provided with the elastic unit, and the elastic unit can effectively prevent the bridge hinge joint from cracking due to thermal expansion; the reinforcing device can effectively transfer shearing force, so that the hinge joint of the bridge is reinforced.
In order to achieve the above object, the present invention adopts the following technical means.
The utility model provides a reinforced structure of bridge hinge joint, includes two adjacent hollow bridge floor slabs, leaves the hinge joint between two adjacent hollow bridge slabs, still includes bridge hinge joint lower part and is provided with fixed unit, fixed unit includes the steel sheet with the laminating of the hollow bridge floor face, the steel sheet respectively with the hollow slab bottom surface fixed connection of bridge hinge joint both sides, the steel sheet is equipped with the bellied grafting portion that makes progress in corresponding hinge joint department, fixed connection elastic element in the grafting portion, elastic element is including hugging closely curb plate, rubber spring and the flat board of bridge hinge joint, dull and stereotyped both ends are connected fixedly with the top of both sides board respectively, are equipped with the spring layer in the space that both sides board and flat board formed, the both sides on spring layer respectively with both sides board fixed connection, the elasticity direction on spring layer is on a parallel with the flat board.
Further, the steel plate is fixedly connected with the bottom surface of the hollow plate through bolts, and structural glue is filled in the bolt holes to be anchored.
Furthermore, the insertion part is perpendicular to the steel plate, and two side plate surfaces of the insertion part are tightly attached to the side wall of the lower part of the hinge joint.
Furthermore, the spring layer is composed of rubber springs, the rubber springs are small in elastic modulus and are large in elastic deformation after being loaded, so that impact and vibration are absorbed, and the rubber springs can be simultaneously loaded in multiple directions, so that the bridge hinge joint can be further reinforced.
The invention has the beneficial effects that: the reinforcing device comprises a fixing unit and an elastic unit, wherein the elastic unit can effectively prevent the crack phenomenon of the bridge hinge joint caused by thermal expansion; the reinforcing device can effectively transfer shearing force, so that the hinge joint of the bridge is reinforced.
