Description
Comb type Bridge Expansion Joint is to coordinate the rotate of the bridge end and longitudinal displacement caused by natural factors, for example,when the temperature changes,the bridge occurs expansion and longitudinal deformation, vehicle loading also can cause the rotate of the bridge end and longitudinal displacement. In order to let the vehicle smoothly through the bridge deck and meeting bridge deck deformation ,need setting certain flexible device at the bridge expansion joint. This device is called the bridge expansion joints. The comb type expansion joint is in order to adapt to the modern highway transportation,then development the expansion joint products with the characteristics of waterproof, dust-proof, anti-skid, anti-corrosion, prevent noise .

Main features of comb type expansion joint device:

Large amount of expansion and shallow buried steel comb type expansion joint device, design allows for 40 ~ 1000 mm is suitable for various expansion amount not beam structure, different span of building Bridges and old bridge rebuilding, large scale, wide scope of use.Steel comb type expansion joint device, the overall structure height 30 ~ 40 mm.All without changing the original structure of beam end, shallow buried can achieve effective anchoring strength.Under normal circumstances, the expansion amount > 80 mm, the other types of telescopic device the overall height is high, the overall height > 250 mm deformed steel telescopic device.Design, must carry on the special treatment on the beam end structure, increase the difficulty of construction at the same time as a result, large scale, shallow buried fully shows the unique technical advantages of the telescopic mechanism.

Comb type telescopic gap automatic slag removal Various types of telescopic device, a common problems generally.Telescopic gap, ash, hard plug, serious when affect the normal expansion of beam body.Steel comb type expansion joint device, due to the special processing structure, comb telescopic gap is located in a single beam end face, comb type bottom has a stainless steel board pad at the same time, ash and hard objects can only stay in surface, so that can use comb type steel telescopic process and the effect of vehicle, ash, hard objects automatically discharge telescopic gap, so as to not cause blockage, does not need manual cleaning, do not affect the normal expansion of beam body.

Has excellent waterproof and dustproof performance.Steel comb type expansion joint device set neoprene waterproof layer on the second floor, and pour out around a comb type steel telescopic gap waterproof ointment, achieve excellent waterproof and dustproof function, effectively protect the bridge structure and delay the corrosion of bearing, extend the service life of bridge.

The telescopic device and pavement performance on the whole .Steel comb type expansion joint device which is based on firm soft measures, such as more thoroughly removes the car from the structure when the conditions of the vehicle, on both sides of the telescopic device using high grade ribbon-like rigid concrete protection, good rigidity as a whole.Therefore, traffic smoothly, no impact vibration, reduce the impact of the bridge, reduce noise, prolong bridge and vehicle use fixed number of year.
