Background
At present, the expansion devices for domestic and foreign bridges mainly comprise a modular type (including a single slit), a comb plate type, a seamless type and the like. These several devices have the following characteristics:
the modular product is made of section steel, a seam is reserved between the section steel to adapt to displacement, and the surface of the section steel forms a wheel bearing surface, so that the modular product is suitable for bridges with various displacement amounts. The defects are that when the vehicle passes through the gap, impact and larger noise are generated, the driving comfort is poor, and the noise pollution is large.
The comb plate type adopts a pair of mutually meshed comb plates to form a bearing surface and a displacement seam, relative to wheels, the driving direction is in continuous transition, the impact generated by the vehicle passing through is small, the noise is low, and the driving is comfortable. The defects are that after the wheels rapidly pass through and are separated from the comb plate, the inertia of the comb plate rebounds, and the connecting parts are easy to be fatigued to cause looseness, falling or damage, so that the driving safety is influenced.
In recent years, scientific research institutions and manufacturing enterprises at home and abroad fully combine the advantages of a digital mode and a comb plate mode, and develop a series of noise reduction telescopic devices, but rubber strips cannot be maintained and replaced, most of all, the rubber strips cannot adapt to the working condition of large displacement 160 or above, and the displacement 240 can be achieved to the maximum extent.
