Abstract
The utility model discloses an expansion joint device of a bridge, which comprises an expansion joint frame arranged in a pavement gap, wherein a hollow groove is arranged in the expansion joint frame, and the expansion joint device is characterized in that an elastic filling piece with the shape matched with the hollow groove is arranged in the hollow groove, an elastic cover plate is arranged on the upper sealing cover of the hollow groove, the elastic cover plate is fixedly connected with the top surface of the expansion joint frame through a viscous connection cushion layer, and the elastic filling piece is abutted on the elastic cover plate; the advantage is that the cost is lower, and the construction is comparatively quick, can prevent effectively that sewage, solid rubbish from getting into the dead slot, improves expansion joint device's life, through the top surface fixed connection of adhesive connection bed course with elastic cover plate and expansion joint frame, can prevent effectively that expansion joint frame from causing elastic cover plate to take place to break away from because of flexible deformation, and elasticity filler top connects on elastic cover plate, plays the prevention of seepage jointly and prevents effects such as sediment, buffering shock attenuation, noise reduction.
Description
Technical Field
The utility model relates to an expansion joint structure, especially an expansion joint device of bridge.
Background
The expansion joint is a structural joint arranged along a proper position in the direction of a building or a construction joint of a structure in order to prevent the building structure from cracking or destroying due to the load action corresponding to the expansion deformation of the building structure caused by the change of the climate and temperature, and the expansion joint of the existing bridge mainly has the following problems: because the traffic volume is big, the solid rubbish blocks up seriously and can't normally work in the bridge expansion joint, and bridge management and maintenance department maintenance personnel regularly clear up the numerous solid rubbish in the expansion joint and hardly realize at present stage, cause the expansion joint function can't reach the design function to lead to following series serious consequence: 1) the anchoring area of the expansion joint connected with the bridge or the road is more easily damaged due to the accumulation of solid garbage in the joint under the coupling action of adverse factors such as wheel impact load, rainwater and the like; 2) the bridge girder can not extend under the action of high temperature in summer, so that two ends of the girder, the bridge deck and the bridge abutment are damaged by extrusion; 3) the rubber waterstop of the expansion joint is easy to age and damage under the action of adverse environmental factors such as ozone, rainwater, ultraviolet rays and the like; 4) in rainy days, sewage easily flows into the expansion joint, and the steel members of the joint body, the steel bars of the anchoring area of the expansion joint and the bridge support are easily corroded. Above-mentioned bad consequence can finally lead to bridge expansion joint and bridge life greatly reduced, appears destroying the back when the expansion joint structure, need change it, and construction period is longer, can seriously influence the traffic to bring great economic burden.
Disclosure of Invention
The utility model aims to solve the technical problem that an expansion joint device of bridge that can effectively play buffering cushioning effect and construct fast and conveniently is provided.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides an expansion joint device of bridge, is including setting up the expansion joint frame in the road surface gap, the expansion joint frame in be provided with the dead slot, the dead slot in be provided with the shape with the elastic filling piece that the dead slot matches, the dead slot on sealed lid be equipped with the elastic cover board, the elastic cover board with the top surface of expansion joint frame pass through adhesive bonding bed course fixed connection, the elastic filling piece top connect in the elastic cover board on.
An elastic shaping piece is arranged between the elastic filling piece and the elastic cover plate, and the elastic cover plate is positioned at the elastic shaping piece and arched upwards. The elastic shaping piece can adopt high-compressibility elastic profiles such as foam strips, so that the construction is more convenient, the buffering effect is better and the cost is saved; the elastic cover plate is located at the elastic positioning piece and arches upwards, so that the falling solid garbage can roll downwards to two sides of the arched position, and the solid garbage is prevented from being continuously pressed into the elastic cover plate when a vehicle passes through, and the elastic cover plate is prevented from being damaged.
The upper surface of the elastic shaping piece is an arc surface which is arched upwards. The design effect is better, makes the holding power that the position that upwards arches of elastic cover plate received more stable.
The end of the elastic cover plate extends to the external road surface and is provided with an extending part, the extending part is a slope structure with the thickness gradually increasing from outside to inside, and the adhesive connecting pad layer extends outwards and is arranged between the extending part and the road surface. The vehicle is comparatively steady during the process, and has further increased the firm in connection nature between elastic cover and the expansion joint frame to elastic cover takes place to break away from when further avoiding the deformation of expansion joint frame.
Compared with the prior art, the utility model has the advantages that the elastic cover plate is covered on the empty groove of the expansion joint frame, thereby effectively preventing sewage and solid garbage from entering the empty groove, reducing maintenance cost, preventing the rubber waterstop of the expansion joint frame from accelerated aging due to the action of adverse environmental factors such as ultraviolet rays, rainwater and ozone, and prolonging the service life of the expansion joint device; the cover plate is wide, the elastic cover plate is fixedly connected with the top surface of the expansion joint frame through the adhesive connection cushion layer, and the elastic cover plate can be effectively prevented from being separated when the expansion joint frame is deformed in a stretching mode, so that sewage and garbage enter the empty groove and damage to the interior of the expansion joint frame is caused; the elastic filling piece is abutted against the elastic cover plate, and plays roles of seepage prevention, slag prevention, buffering and shock absorption, noise reduction and the like together, so that the driving comfort of a vehicle is improved; the materials of the elastic cover plate, the viscous connection cushion layer and the elastic filling piece can be conventional materials, the economical efficiency is good, the construction can be directly carried out on the original expansion joint frame, the construction is rapid, the influence on the traffic degree is small, and the vehicle can be driven after the construction is finished.
