How to set the kerf surface joints sealing quota
According to design requirements. The expansion joint is the expansion joint, usually with the asphalt board contraction seam, divides into the crosswise contraction joint and the longitudinal contraction joint. Longitudinal contraction joints can be one transverse contraction joint with SMA ester filling. Depends on the design drawings
The expansion joint divides the building components above the base, such as wall, floor and roof (except wood roof) into two separate parts, so that buildings or structures can be horizontally extended in a long direction.
The telescopic seam building expansion, is a means to prevent the building component due to climate change in temperature (heat expansion and cold contraction), the structure cracks or damage the buildings or structures construction of a tectonic setting the direction of the appropriate parts of sewing seam.
The road is generally set expansion joints, and saw the two caulking ointment is broken by quota; sealing area to calculate the kerf figured according to the extension.
