PC endurance plate installation methods
1。 The embedded installation
1) Endurance plate protective film will affect and seal glue, so it should be taken before embedded in the PC will be embedded part of the protective film to remove 5 - 250px。
2) Endurance plate embedded, needs to have appropriate embedding quantity and space, such as embedded quantity is too little, the PC endurance plate may be due to wind or other weight loss; Such as the expansion space is not enough, PC board may also be due to inflation pressure endurance, cause damage.
2。 Screw installation method
1) PC endurance plate must be taken into consideration the size of the screw holes of summer and the heat to heat day and night, when drilling to install sheet to allow the expansion of the shift, in case of heat bilges cold shrink, in general, the plank of drilling hole diameter should be 50% larger than the diameter of a bolt or rivet.
2) The location of the screw holes from the edge of the PC endurance plate is too close, very easy to cause fracture phenomenon, in general, the position of the screw holes from the PC board on the edge of the distance of not less than 50 mm. Screw cannot too tight, otherwise deformation blowout, and cause stress.
3) The distance between the screw, can according to the thickness, do proper configuration, army spacing is too small and too bad, such as the spacing is too small, sometimes stress caused by too tight, cause damage; Such as spacing is too big, and may make the PC endurance plate fixed instability. Suggest screw shoulds not be too tight, every 1250 px or more with a screw ( The larger the plate, the thickness of the screw spacing) 。
4) To reduce the pressure of screw for plate directly, can use gaskets pad during filling, but some PVC gasket, rubber washer or bituminous waterproof adhesive damage PC endurance plate, do not use. Recommend the use of the gasket material of epdm, silicone rubber and neoprene.
5) Cold bending processing, the bending part to avoid using screws.
