1. When installing perforated calcium silicate boards, vertical watch plates should be used to avoid horizontal joints as much as possible; The outer part of the board should fall in the middle of the main keel (the spacing between the main keels should closely match the width of the board); When the wall is both high and larger than the board height, a horizontal main keel should be added at the vertical joint of the board.
2. When installing a two-layer perforated calcium silicate board cement board partition wall, the fixation method of the layer board is the same as that of a single-sided perforated calcium silicate board; The tensile joint of the second layer of perforated calcium silicate board cannot fall on the same vertical main keel as the layer joint (including the vertical joint).
3. The installation method of the calcium silicate board partition wall with floor tiles is the same as that of a single sided calcium silicate board wall, but the bright side of the board must be facing the main keel and the rough side should be facing outward during installation, so that the cement mortar can blend well with the board; Apply 6mm thick 1:1 mixed mortar and 107 adhesive bonding layer on the rough calcium silicate board, and then bond 5mm thick floor tiles on the bonding layer.
4. 4mm for plate and main keel × The 25mm Self-tapping screw is fixed, the spacing between screw cores near the plate is ≤ 200mm, and the spacing between screws in the middle of the plate is ≤ 300mm.
5. Fill the joint of the board with putty powder, then apply paper tape at the joint, apply putty, and polish it flat; The preparation of calcium silicate board filling putty powder is as follows: Shuangfei powder 6, gypsum plaster 1, 107 glue, and the water should be adjusted to be suitable for work (adding caulking gypsum is to better fill the joint and have micro plasticity); Generally, the joint filling area is embedded 2-3 times in batches; The total width of the joint is generally 5-7mm.
6. Because the total width of the overlap between the control panel and the ceiling keel reinforcement is small (about 20mm), the spacing specification of the main keel must be maintained vertically.
In fact, the installation of perforated calcium silicate boards and light steel keel partitions is also very simple, saving costs and not looking too heavy during summer work. The size can also be applied by cutting furniture panels anytime and anywhere. It used to be that when someone cut furniture boards, they all cut out flowers. It's also what the Pentagram is. I'm not sure if a kindergarten will be built, it must be so childlike. Overall, perforated calcium silicate boards are very easy to laser cut.
