Abstract
The utility model discloses an external heat-preserving structure of a wall body. The external heat-preserving structure comprises the wall body, wherein a fixing layer, a heat-preserving layer, a protecting layer and a decorating layer are sequentially arranged on the surface of the wall body, wherein the heat-preserving layer is an inorganic rock wool board or belt; the inorganic rock wool board or belt is fixedly arranged on the surface of the wall body through a building adhesive layer; the protecting layer is arranged on the surface of the inorganic rock wool board or belt and comprises a rendering coat mortar layer and a fiberglass grid fabric layer which is buried in the rendering coat mortar; and the decorating layer is arranged at the outside of the protecting layer. The external heat-preserving structure has the advantage that: the inorganic rock wool board or belt serves as the heat-preserving layer, so the flame level is level A, and the fireproof performance of the external heat-preserving structure of the wall body is greatly improved.
Description
Technical field
The utility model relates to building and energy-conservation technical field, specifically a kind of outer wall heat insulating structure that adopts inorganic rock wool.
Background technology
Because several big fire, fire prevention becomes the building energy conservation focus.The organic insulation materials of the most employing of external thermal insulation system at present, the organic insulation material good heat insulating, but the burning grade can only reach B1 or B2 level.
Summary of the invention
The purpose of the utility model is to provide a kind of inorganic rock wool external wall outer insulation wall body structure, and the burning grade of this kind inorganic insulating layer is A level (not firing).
To achieve these goals; The technical scheme of the utility model is following: a kind of outer wall heat insulating structure; It comprises body of wall, it is characterized in that: the surface at body of wall is provided with fixed bed, insulation layer, overcoat and finish coat successively, and described insulation layer is inorganic rock cotton board or band.Described overcoat comprises finishing mucilage layer and glass fiber reticular cloth layer, finishing mucilage layer parcel glass fiber reticular cloth layer.Fixed bed is the building adhesive-layer; Inorganic rock cotton board or band are fixed on the body of wall through building adhesive-layer and crab-bolt, in inorganic rock cotton board or belt surface overcoat are set, and this overcoat comprises the finishing mucilage layer; And be embedded in the glass fiber reticular cloth layer in the finishing mucilage layer, at overcoat arranged outside finish coat.
When inorganic rock cotton board tensile strength is the 7.5kpa grade, in inorganic rock cotton board or belt surface overcoat is set, crab-bolt is set on the overcoat, crab-bolt penetrates overcoat and is fixed in body of wall to inorganic rock cotton board or band, and crab-bolt quantity is no less than 6/m2.When the tensile strength of inorganic rock cotton board or band was other grade, inorganic rock cotton board or band were fixed in surface of wall through the building adhesive-layer, crab-bolt directly is set on the inorganic rock cotton board is connected with body of wall, and crab-bolt quantity is no less than 6/m2.
The advantage of the utility model is that the burning grade of insulation layer is A level (not firing), thereby has improved the fireproof performance of external heat preserving structure for exterior wall greatly owing to adopt inorganic rock cotton board (band) as insulation layer.
Description of drawings
Fig. 1 is the sketch map of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
The utility model is a kind of thermal insulation wall of exterior wall facing structure; It mainly comprises body of wall 1; It is different from prior art and is: the external surface at body of wall 1 is provided with fixed bed 2, insulation layer 3, overcoat and finish coat 6 successively; Said insulation layer 3 is inorganic rock cotton board or band, and described overcoat comprises finishing mucilage layer 4 and glass fiber reticular cloth layer 5, and glass fiber reticular cloth layer 5 is wrapped in the finishing mucilage layer 4.Fixed bed during practical implementation is the building adhesive-layer, and the thickness of building adhesive-layer is 3-10mm; Insulation layer adopts inorganic rock cotton board or band, and burning grade A level has improved the fireproof performance of outer heat preservation system greatly.Rock cotton board coefficient of thermal conductivity≤0.040W/m.K; Rock wool band coefficient of thermal conductivity≤0.048W/m.K; Burning grade A level, fusing point is greater than 1000 ℃, and acidity coefficient should be not less than 1.6, and water absorption should be not more than 1.0kg/m
2
Look the difference of the energy-conservation requirement of construction wall during concrete operations, of is 3mm-10mm, and insulation layer thickness is 30-300mm.The thickness of finishing mucilage layer is 2-4mm.Finish coat is a dope layer, looks the various textures effect, and the thickness of finish coat (containing decoration mortar) is 0.8-2mm.
The utility model be at building-site after relevant operation construction, the external heat preserving structure for exterior wall that on outer surface of wall, forms, rock cotton board or band is fixing at surface of wall earlier with the building viscose glue, additional again crab-bolt, crab-bolt quantity is no less than 6/m
2, and then buried glass fiber reticular cloth at rock cotton board or belt surface with finishing mucilage and form overcoat, finish coat is set at last, form the outer insulation construction of outer body of wall.When rock cotton board tensile strength was the 7.5kpa grade, crab-bolt penetrated overcoat and is fixed in basic unit's body of wall; When rock wool or band tensile strength when be other grade, crab-bolt is fixed in basic unit's body of wall through insulation layer.The crab-bolt of said fixing layer, the inorganic rock cotton board (band) of insulation layer, the fiberglass gridding cloth in the overcoat is the existing product of buying from market, does not specifically describe at this.
