Structural design of metal exterior wall engraving board external thermal insulation engineering system
1 Metal exterior wall engraved board composite leveling slurry external wall insulation system consists of bonding layer, interface agent, rock wool board, leveling slurry layer (with post-galvanized welded wire mesh), surface layer (with alkali resistance) Glass fiber mesh) and finish layer.
2 Rockwool board reinforced mesh thin plastering exterior insulation system consists of bonding layer, interface agent, rock wool board, plastering layer (with alkali-resistant glass fiber mesh cloth) and facing layer
3 The length of the metal exterior wall carved board shall not exceed 1200mm and the width shall not exceed 600mm.
4 The distance between the lower side of the first row of rock wool board and the scattered water at the bottom of the system shall be not less than 200mm, and shall not be greater than 600mm, and shall be insulated by EPS, XPS or rigid foam polyurethane. frame.
5 After the hot-dip galvanized welded wire mesh lap width should be no less than 100mm (or two complete grid), the lap joint should be tied firmly.
6 The anchor bolts of the fixed rock wool metal exterior wall engraving board and the post-galvanized welded wire mesh shall not be less than 6 per square meter.
7 Waterproof interface agent should be sprayed on both surfaces of the rock wool board and the side of the board. 5.2.8 The thickness of the leveling slurry should not be less than 20mm
