At present, with the advantages of high-cost performance, easy installation, excellent heat insulation effect, acid and alkali resistance, PVC roof sheets are more and more commonly used in various buildings. However, in the installation and use, some installation problems have not been corrected in time, which has greatly shortened the service life of the PVC roof sheet. First of all, PVC roof sheet is perforated regularly during installation, and fixing is an important part of successful installation. How to punch holes correctly when installing PVC roof sheet?
Play more attention during the opening of the PVC roof sheet, otherwise the PVC roofing will crack and cause leakage during use. When drilling a hole with a pistol, a plastic special drill bit is used. Considering the factors of thermal expansion and contraction, the diameter of the drill bit is slightly larger than the diameter of the fixed part by 1MM. When drilling the hole, the micro-edge should be kept smooth to avoid stress concentration, and the drilling should be special when the weather is cold. When using self-tapping screw to holes, it is forbidden to directly penetrate the wave board.
If the hole punch installation is not performed correctly, it will seriously affect the service life of the PVC roof sheet.
