The purpose of this utility model provides a kind of used for building exterior wall insulation mineral wool compound structure, to overcome many deficiencies of the prior art.
For achieving the above object, the skill scheme that the utility model adopts is: this compound structure comprises by anchor studs and is fixed on mineral wool board fiber coating insulation layer on the external wall external surface, be fixed on steel mesh enhancement layer on the mineral wool board fiber coating insulation layer external surface by the anchor studs outer end, spread upon the mortar levelling layer on the steel mesh enhancement layer external surface, spread upon the polymer mortar overcoat on the mortar levelling layer external surface.
The utility model is a kind of compound structure that is made of mineral wool board fiber coating insulation layer, polymer mortar overcoat net and steel mesh enhancement layer.Has sound construction, advantage high temperature resistant, ageing-resistant, that thermal conductivity is low and acidproof, alkaline-resisting, salt spray resistance, characteristic such as nontoxic, tasteless.Reach building A level noninflammability energy after tested, be applied in the generation of having stopped fire incident on the external wall.Owing to having very high heat stability and weatherability, corrosion resistance, service life is at least more than 30 years simultaneously.The utility model is a kind of novel building exterior wall fireproof heat insulating energy-conserving and environment-protective product, and with its superior cost performance, cheap price will obtain to widely popularize at home.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model.
Five, the specific embodiment
As shown in the figure, the utility model comprises by anchor studs 8 and is fixed on mineral wool board, fiber coating insulation layer 2 on the external wall external surface 1, be fixed on steel mesh enhancement layer 3 on mineral wool board fiber coating insulation layer 2 external surfaces by anchor studs 8 outer ends, spread upon the mortar levelling layer 4 on steel mesh enhancement layer 3 external surfaces, spread upon the polymer mortar overcoat 5 on mortar levelling layer 4 external surface.
1. exterior wall external surface
Exterior wall external surface 1 should guarantee the no lime-ash in surface, not have peeling and do not have dust as the basal plane of this structure product.
2. mineral wool board fiber coating insulation layer
At first on exterior wall external surface 1, install and fix mineral wool board 9 with special-purpose anchor studs 8 by designing requirement.Reserve 100mm～150mm gap between the mineral wool board 9, and then fill above-mentioned gap with the mineral wool fiber spraying.This insulation layer is actually by mineral wool board 9 and is used for airtight, the jointless integral heat insulation layer that the mineral wool fiber sprayed coating 6 in infill panel gap constitutes.Because the coefficient of thermal conductivity of mineral wool fiber is generally less than or near polystyrene, this insulation layer is no seam, whole closed structure again in addition, its heat insulating effect is more much better than traditional polystyrene board.Mineral wool board 9 is with mineral fibers and adhesive material, by the produced product of automatic production line.Its technical requirements is apparent density 100～120kg/m
3, coefficient of thermal conductivity≤0.04 (W/mk), thickness deviation ± 2mm, specification 1000mm * 630mm; Burning grade A level; Nonpoisonous and tasteless, do not go mouldy.Mineral wool fiber spraying is to adopt the fiber coating machine, will be ejected on exterior wall mineral wool board 9 gaps through after pretreated mineral granulated wool and adhesive special even mixing of moment.The mineral granulated wool is the centrifugal cotton shape commodity of an inorfil that forms that get rid of of a kind of high temperature melting.Mineral granulated wool technical requirements: average fibre diameter φ 4.0 μ m, slag ball content＜4.5%; Burning grade A level, nontoxic, "dead".The spraying adhesive special is the aqueous binders product that the strong emulsion polymerization of a kind of adhesion stress, auxiliary agent mix with fire retardant.Spraying adhesive special main technical requirements: fire-retardant, solid content 50%, adhesion stress is strong, water-fast, weather-proof after the film forming; Nontoxic, tasteless, do not go mouldy.Stretch out from the external surface of mineral wool board 9 outer end of above-mentioned anchor studs 8.
3. steel mesh enhancement layer
After mineral wool board, fiber coating insulation layer 2 complete, hang steel mesh enhancement layer 3 in its surface shop, and with the zinc-coated wire colligation on the anchor studs 8 that the external surface from mineral wool board 9 stretches out.In order to prevent that mineral wool board fiber coating insulation layer 2 from coming off, strengthen the bond strength of insulation layer 3 and leveling layer 4.The steel mesh that the steel mesh enhancement layer adopts is a galvanized electric welded mesh.Anchor studs 8 is the special-purpose anchor studs of magnetic tape trailer hole thermal-insulating type.
4. mortar levelling layer
