Abstract
The utility model relates to a thermal insulation fireproof structure of an external wall, which is characterized in that a fixed layer, an insulating layer and a finish coat are sequentially arranged on the outer surface of a wall body; and an isolation strip is arranged in the insulating layer. During use, the fixed layer, the insulating layer and the finish coat are sequentially arranged on the outer surface of the wall body, the insulating board layer is commonly made of an expandable polystyrene (EPS) board, a rock wool board (strip) is arranged in the position of the isolation strip, a protective layer comprises a rendering coat mortar layer and a glass fiber grid cloth layer, the glass fiber cloth grid layer is coated with the rendering coat mortar layer, and the finish coat commonly is a building coating. Inorganic rock wool is used as the insulation isolation strip, so that the fireproof performance of an external thermal insulation system is greatly improved.
Description
Technical field:
The utility model relates to the technical field of building energy conservation, specifically a kind of external wall outer insulation fire barrier structure that adopts inorganic rock wool.
Background technology:
The organic insulation materials of the most employing of external thermal insulation system at present, the organic insulation material good heat insulating, but fireproof performance is not good enough.Because high building big fire in recent years is in case generation often causes huge personnel and property loss, so improve the outstanding request that the fireproof performance of external wall outer insulation becomes building energy conservation at present.
Summary of the invention:
The purpose of the utility model is to provide a kind of improved exterior-wall heat insulation fire barrier, in case it can overcome the some shortcomings that the not good fire of exterior wall heat-preserving system fireproof performance in the prior art causes the heavy losses of personnel, property easily.
To achieve these goals, the technical scheme of the utility model is: a kind of exterior-wall heat insulation fire proof construction, it mainly comprises body of wall, it is characterized in that: the external surface of body of wall is provided with fixed bed, insulation layer and finish coat successively, is provided with the isolation strip in the insulation layer.
During use; The utility model is provided with fixed bed, insulation flaggy, overcoat and finish coat successively on the surface of body of wall; Described insulation flaggy is generally expansion polystyrene plate (EPS) plate, and the place, isolation strip is rock cotton board (band), and described overcoat comprises finishing mucilage layer and glass fiber reticular cloth layer; Finishing mucilage layer parcel glass fiber reticular cloth layer, finish coat is the application layer or pastes ceramic veneer.Owing to adopt inorganic rock wool as the insulation isolation strip, improved the fireproof performance of outer heat preservation system greatly.
Description of drawings:
Fig. 1 is the structural representation of the utility model one embodiment
The specific embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe.
The utility model mainly comprises body of wall 1, and its difference with the prior art is: the external surface of body of wall is provided with fixed bed 2, insulation layer 3 and finish coat 6 successively, is provided with the isolation strip in the insulation layer.The isolation strip of insulation layer adopts inorganic rock cotton board to process, and the remainder of insulation layer adopts expansion polystyrene plate to process, and the thickness of insulation layer is 20-300mm.Be provided with overcoat between insulation layer and the finish coat, overcoat is made up of finishing mucilage layer 4 parcel glass fiber reticular cloth layer 5, and the thickness of finishing mucilage layer is 2-4mm.Finish coat adopts dope layer or ceramic veneer layer, and the thickness of dope layer is 0.8-2mm, and the thickness of ceramic finish coat is 10-20mm.The thickness of fixed bed is 3mm-10mm.
In the enforcement of external thermal insulation system, eaves is no more than the rock wool fire barrier that the 500mm place is provided with horizontal circle on apart from window.For housing construction, height is more than or equal to the building of 60m less than 100m, and when adopting B2 level heat insulating material, every layer should be provided with horizontal fire barrier; Height is more than or equal to the building of 24m less than 60m, when adopting B2 level heat insulating material, whenever two-layer horizontal fire barrier should be set; Height is less than the building of 24m, and when adopting B2 level heat insulating material, per three layers should be provided with horizontal fire barrier.For other civilian construction, height is more than or equal to the building of 24m less than 50m, when adopting B1 level heat insulating material, whenever two-layer horizontal fire barrier should be set; Height is less than the building of 24m, and when adopting B2 level heat insulating material, every layer should be provided with horizontal fire barrier.The rock wool fire barrier is set, and width is not less than 300mm, and carries out gross area and paste.
Fixed bed is fixed for building viscose glue and dish type crab-bolt, the thickness 3-10mm of building adhesive-layer; Insulation flaggy in place, isolation strip adopts inorganic rock cotton board (band), makes the combustibility of warming plate bring up to the A level from B1 level and B2 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; Fire-protection rating A level, fusing point are greater than 1000 ℃, and acidity coefficient should be not less than 1.6, and water absorption should be not more than 1.0kg/m
2Thickness is got and the consistent 20-300mm of being of the EPS plate thickness of main wall face during concrete operations.Finishing mucilage among the embodiment has two kinds of cement based and non-cement based, is respectively Sto protection mortar and the Sto fiber reinforcement glue of plastering, and the thickness of finishing mucilage layer is 2-4mm.Finish coat is dope layer or ceramic veneer layer, when adopting coating to be finish coat, looks the various textures effect, and the thickness of finish coat (containing decoration mortar) is 0.8-2mm; During for the tile decorative surface layer, finish coat thickness is 10-20mm.
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 wool is fixed with building viscose glue and dish type crab-bolt at surface of wall earlier; When rock wool tensile strength was the 7.5kpa grade, holdfast need penetrate the grid cloth protective facing and be fixed in basic unit's body of wall; When rock wool tensile strength was other grade, holdfast saw through insulation layer and is fixed in basic unit's body of wall; And then buried glass fiber reticular cloth on the rock wool surface with finishing mucilage and form overcoat, finish coat is set at last, form the outer insulation construction of outer body of wall.
