Background
The bridge expansion device is an important component of a bridge end, has the function of preventing rainwater or accumulated water of other bridge floors from directly flowing into the end of a beam body so as to avoid corroding parts such as a prestressed anchoring system at the end, the beam body and the like, and plays an important role in expansion and contraction of the bridge end, water collection, drainage, water prevention and the like. Meanwhile, the requirements of the two side beam bodies on displacement along the bridge direction, the transverse bridge direction and the vertical direction and the rotation of the beam bodies are met, and the quality and the performance of the two side beam bodies directly influence the durability of the whole bridge.
In recent years, with the increase of investment of infrastructure, bridge construction is rapidly developed, and the construction of bridges such as large-span bridges, cable-stayed bridges, suspension bridges and the like is more and more, and the bridges put new requirements on the performance of the expansion device. Traditional fishback telescoping device has through steady, and the noise is low grade advantage, but to the bridge because of the vertical corner displacement that load and other exogenic actions arouse or because of the bridge subsides the traditional fishback telescoping device of the beam surface difference that produces just hardly adapt to.
In order to adapt to vertical corner displacement caused by load and other external force actions on a bridge or beam surface height difference change caused by bridge settlement, people set a vertical displacement rotating shaft through a unit type multidirectional displacement comb plate type telescopic device, but do not realize separation of a rotating system and concrete, so that the rotating shaft is wrapped by the concrete and cannot rotate, or the rotating shaft peels off the concrete wrapped on the surface of the rotating shaft to cause damage to the telescopic device.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a construction convenience, after the big corner of bridge rotates or subsides, the multidirectional broach type telescoping device that shifts that the vehicle can steadily pass through, long service life.
In order to solve the above problem, the utility model discloses the technical scheme that multidirectional broach type telescoping device that shifts adopted does: including main fishback, main fishback anchor mechanism, vice fishback anchor mechanism and the waterstop that is located main fishback below, being close to the below of vice fishback one side is provided with the stainless steel slide below is provided with the yielding rubber board, main fishback is including the preceding main fishback that has the broach and back main fishback, preceding main fishback with back main fishback swing joint, main fishback anchor mechanism with back main fishback is connected preceding main fishback below is provided with strong magnet, the strong magnet lower extreme is fixed with the roof beam body.
The additional technical characteristics are as follows:
the front main comb plate is connected with the rear main comb plate through a tenon structure;
magnet holes are formed in the damping rubber plate and the stainless steel sliding plate, and the powerful magnets are located in the magnet holes;
the powerful magnet is located below the comb teeth of the main comb plate.
The utility model provides a multidirectional broach type telescoping device that shifts compares with prior art, has following advantage: firstly, the main comb plate anchoring mechanism, the auxiliary comb plate anchoring mechanism and the water stop belt positioned below the main comb plate are included, the stainless steel sliding plate is arranged below one side close to the auxiliary comb plate, the damping rubber plate is arranged below the stainless steel sliding plate, the main comb plate comprises a front main comb plate and a rear main comb plate, the front main comb plate is movably connected with the rear main comb plate, the main comb plate anchoring mechanism is connected with the rear main comb plate, the strong magnets are arranged below the front main comb plate, the lower ends of the strong magnets are fixed with the beam body, when the vertical rotation angle is caused by the action of load and other external forces or the beam surface height difference is generated by the settlement of the bridge, the auxiliary comb plate and the rear main comb plate are respectively fixed with the beam body, and the front main comb plate is always tightly attracted on the beam body under the action of the strong magnets, at the moment, the space between the front main comb plate and the auxiliary comb plate is smoother, vehicles can stably and safely pass through the front main comb plate, the service life is longer, and the damping rubber plate is positioned below the stainless steel sliding plate and plays a role in damping and reducing noise; the stainless steel sliding plate and the front main comb plate form a sliding pair, so that free expansion of the bridge beam end is ensured; secondly, the front main comb plate is connected with the rear main comb plate through a tenon structure, so that the structure is firmer and the rotation is more flexible; thirdly, as the damping rubber plate and the stainless steel sliding plate are provided with the magnet holes, the strong magnets are positioned in the magnet holes, so that the strong magnets are more firmly fixed, and the attractive force between the strong magnets and the front main comb plate is larger; fourthly, because powerful magnet is located the broach below of main fishback, the arm of force of powerful magnet and the effort of broach is long, and the turning moment who produces is bigger.
