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.
