1. According to the design drawings and the actual construction situation, cut and open the plate. Chamfering shall be carried out on site if necessary. Chamfering has been done on both sides of cement fiber board. However, when the wall is higher than 2440, the short side of horizontal joint of cement fiber board must be chamfered on site. In order to better handle the joint

2. Snap a line on the surface of the cement fiber board and mark the fixing point of the self tapping screw, and pre drill the concave hole. The distance between the self tapping screw and the plate edge is 15, the distance from the plate angle is 50, and the middle distance of the self tapping screw is 200-250

3. The partition board is generally laid longitudinally, that is, the long side of the board is fixed on the vertical keel, and the edge of the cement fiber board is respectively fixed on the keel along the top (ground) or the cross bracing keel, and the boards should be naturally close when butting

4. Be able to press in place: the board joints on both sides of the wall should be staggered with each other and should not fall on the same keel. The cement fiber board should be fixed with self tapping screws. When fixing, it should be fixed from the middle part of the plate to the periphery

5. When installing the plate around the door and window, the plate joint shall not fall on the keel of the fixed door frame, so as to avoid the crack of the plate joint caused by the frequent opening and closing vibration of the door and window
