Expansion joint of bridge expansion joint:

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.

Automatic clearance of comb type telescopic clearance

Telescopic device of different types, generally there is a common problem in the gap. The telescopic ash, hard blockage, affect the normal expansion beams seriously. The plate comb type expansion joint device, due to the special structure, end comb telescopic gap located in unilateral beam, while the comb type bottom surface of stainless steel slide ash cushion, and hard objects can only stay in the surface, which can help the stretching process and vehicle driving plate comb function, automatic ash discharge, hard expansion gap, so as not to cause blockage, no need to clean up, does not affect the normal telescopic ring beams.
