The hardware is made of stainless steel, hot-dip galvanized or copper (primarily to prevent rust and corrosion in the future and affect the fastness of the connection). Please drill holes in advance to prevent cracking of Changsha antiseptic wood.
Fixed laying method: fix the keel on the ground with expansion screws, use nylon raw materials for expansion screws (anti-aging is better), iron expansion pipes should be painted with anti-rust paint, and then lay anti-corrosion wood; movable laying method : One is to connect the keel with the stainless steel cross screw on the front of the anti-corrosion wood, and the other is to fix the keel on the anti-corrosion wood with screws. Suspended laying method, the keel leveling on the ground can be connected into a frame / truss structure, and then laid anti-corrosion wood.
Treatment of the bottom layer of the wooden structure: In the planning and construction, the air circulation between the anticorrosive wood and the ground should be fully adhered to, which can more effectively extend the life of the bottom layer of the wooden structure.
When manufacturing the Changsha anti-corrosion wood, a gap of 0.2-1CM should be left between the anti-corrosion wood (the gap size is determined according to the moisture content of the wood. When the moisture content of the wood exceeds 30%, it should not exceed 0.8CM). Expansion of antiseptic wood. A square column with a thickness greater than 50mm or greater than 90mm can be grooved on the bac
