Construction technology of antiseptic wood pavement
Thickness greater than 50mm or greater than 90mm square column to reduce cracking in the back of the central position to open a groove.
▲ hardware application of stainless steel, hot-dip galvanized or copper (mainly to avoid future rust corrosion, and affect the connection fastness) to install the installation of pre-drilling, in order to avoid corrosion wood cracking.
▲ wood structure of the grass-roots treatment: design and construction should be fully maintained between the anti-corrosion wood and the air flow between the ground, you can more effectively extend the life of wood structure grassroots.
▲ production and installation of preservative wood, preservative wood between the need to stay 0.2-1CM gap (according to the moisture content of wood and then determine the size of the gap, wood moisture content of more than 30% should not exceed 0.8CM as good) to avoid rain and water The expansion of antiseptic wood;
?
▲ fixed laying method: with the expansion screw or galvanized angle code to the keel fixed to the ground, the expansion of the screw application of galvanized (anti-aging is better), and then with stainless steel cross screw in the front of the antiseptic wood and keel connection laying ;
?
Activity Laying Method:
?
A regular arrangement of the ground keel, and then stainless steel cross screw in the front of the wood and the keel connection
;
B with screws to the keel fixed in the anti-corrosion wood on the back, a few pieces into a whole, neither damage the ground structure, but also free to disassemble and clean;
?
C suspension laying method, keel in the ground leveling can be connected into a frame / well frame structure, and then laying preservative wood.
