SF comb shaped bridge expansion joint expansion capacity, 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. Plate comb type expansion joint device, the overall structure of the height of 30 ~ 40mm. are not to change the original beam structure, shallow buried can to achieve effective anchorage strength. In general, the amount of expansion after the >80mm expansion device of other types of overall height, the overall height of >250mm. shaped steel telescopic device design, must carry out special treatment to the end of the beam structure, and therefore increase the difficulty in construction, a large amount of expansionShallow buried, fully show the expansion device unique technical advantages.
