Modular bridge expansion joints: by a combination of rubber plate and steel plate and bridge engineering, suitable for ordinary highway expansion is less than 12Omm.

The modular joints made of profiled steel by integral molding, the side beam, beam, beam, displacement control system, sealing rubber belt and other components. Its characteristic is the overall good flexural compressive strength is high, when the vehicle passes through the smooth jump, low noise. Applicable to all kinds of bend, slope, slope and the width of the bridge. The design of modular expansion joint displacement according to the modulus of any group according to certain actual needs. Many joints from the spell of the single slit 8Omm to 12OOmm, is divided into 15 levels, the expansion amount is greater than 12OOmm, according to the design requirements of processing and manufacturing, to meet the needs of users. The expansion joints for highway bridge engineering.

The main characteristics of plate comb type expansion joint device:

the expansion amount is large, shallow buried

Comb plate type expansion joint device, the allowable expansion amount of 40 ~ 1000mm is not suitable for all kinds of beam structure, reconstruction of different span new bridge and the old bridge, stretching a large quantity, wide range of use.

Comb plate type expansion joint device, the overall structure of the height of 30 ~ 40mm. are not to change the original beam structure, shallow buried can achieve effective anchorage strength. In general, the amount of expansion after the >80mm expansion device of other types of overall height, special-shaped steel telescopic device overall high degree of >250mm. design, must be special treatment at the end of beam structure, and therefore increase the difficulty in construction, expansion of large, shallow buried fully shows that the expansion device unique technical advantages.
