Expansion Joint Systems

General concept of expansion joint is to provide the continuity between two parts of a structure which are in relative movement because of vibration, seismic load, thermal expansion or contraction, shrinkage etc. Expansion joints are used primarily to relieve stress due to confinement of a slab. An expansion joint is an assembly designed to safely absorb the heat-induced expansion and contraction of various construction materials, to absorb vibration, or to allow movement due to ground settlement or earthquakes Expansion joints are designed to support heavy and rigorous traffic load with minimum noise and bumps so that the driving experience can be with maximum pleasure
  
.Steel structure are to be inserted as shown above in either sides, little lowered position
.Top of the insert shall be at par with finished level of wearing coat to maintain the camber
.Steel structure and main reinforcement bar shall be anchored with proper welding
.If required spacer bar shall be used for proper alignment of bolt and leveling of steel insert  
.Steel structure are to be packed with proper mixture of concrete as same as deck casting  
.With proper alignment, manufacturer's recommended adhesive to be applied on thesteel inserts and the elastomeric slab seal shall be placed over there  
.Elastomeric seal shall be tightened with S.S. nut & bold and shall be locked with washer
.The cavity of the nut & bolt shall be filled with elastomeric plug, duly applying the adhesive recommended by the manufacturer  
.Wearing coat shall be done in the spot,with adequate care to ensure a waterproof joint with the existing wearing coat
.Temperature to be checked before installing the elastomeric slab unit
