Exterior-wall heat insulation, decoration integrated plate
The utility model relates to a kind of building unit, relates in particular to a kind of exterior-wall heat insulation, decoration integrated plate.
Current, building energy conservation is surging forward in the world, and building energy conservation has been that building circle, the whole world is through the later common selection of careful consideration.What building energy conservation was at first referred to is the insulation problem of external wall, and this clause has been the compulsory execution clause of the Ministry of Construction.Present stage, the working procedure of exterior-wall heat insulation was so haply: smear adhesive mortar after the form removable of external wall, paste warming plate, linked network, smear anticracking grout, do finish coat at last again on exterior wall.Wherein, the interior external wall outer insulation sheet material that adopts of industry mainly contains at present: EPS plate and XPS plate.These two kinds with regard to its thermal and insulating performance, its heat inertia index can satisfy energy-conservation requirement fully, but is coming with some shortcomings separately aspect intensity, weatherability, gas permeability, adhesion strength, the surface finish.The deficiency of EPS plate is: first intensity is not high, and weight capacity is lower, need strengthen during outer furring brick handling; It two is that sheet material will be through one period maturity period when dispatching from the factory, and needs to place a period of time just can use.If the curing time deficiency, the quality of sheet material can not be guaranteed, and construction back panel shrinkage makes system's cracking.The weak point of XPS plate is: first XPS plate is difficult to guarantee planeness, and the anticracking grout of outside is difficult to cover up the plate seam, especially at segmental arc, therefore is not suitable for doing the wall insulated board that outside finish is a coating; It two is that the intensity of XPS plate itself is higher, but sheet material is more crisp, is difficult for bending, on the plate if the stress that exists concentrates situation will make that sheet material damages, cracking; It three is that gas permeability is poor, and ventilative hardly, if the temperature difference of plate both sides is bigger, the humidity height is easy to dewfall; It four is that the retractility of its structure is poor, is subjected to the variable effect of temperature and humidity and is out of shape, rises drum and cause insulation layer to come off.In sum, the situation of the insulation of current external wall, decoration site operation is: operation is many and complicated, the defective of these heat insulating materials is exposed nothing left, it is poor to be directed at poor, the exposed heat insulating material fireproof performance of working security, stay serious potential safety hazard, the construction back is of poor quality, architectural appearance is poor, easy to crack, the hollowing of metope, defectives such as lacquer painting peeling.Being carried out if the decoration process of the insulation of exterior wall and exterior wall can take all factors into consideration simultaneously, will be a kind of qualitative leap to present many, high-rise building operations, be the change of revolution.
The utility model content
The purpose of this utility model is exterior-wall heat insulation, the decoration integrated plate that provides the decoration process of a kind of insulation of exterior wall and exterior wall to be taken all factors into consideration at the prior art weak point.
The utility model is by the following technical programs in to realize: a kind of exterior-wall heat insulation, decoration integrated plate, it is characterized in that: it comprises decoration of exterior wall cement board surface layer, middle insulation layer, cement board enhancement Layer, and the mating face of described middle insulation layer and decoration of exterior wall cement board surface layer, cement board enhancement Layer is that convex-concave is joined.
Described cement enhancement Layer back is provided with some back of the body bolt mounting screws hole.
The convex-concave on described mating face is step-like or dovetail groove shape at right angles.
The mating face is symmetric arrangement with the convex-concave on following mating face on the described middle insulation layer.
In the middle of described on the insulation layer convex-concave on mating face and following mating face be and be arranged in parallel.
Insulation layer is an EPS molding foamed polystyrene board in the middle of described.
Insulation layer is an XPS extruded plastic foam polystyrene board in the middle of described.
Good effect of the present utility model is: the exterior-wall heat insulation that the utility model proposes, decoration integrated plate, has following advantage: 1) warming plate is placed between decoration of exterior wall cement board surface layer and the cement board enhancement Layer, sheet material can be finished in precast yard, the job site no longer includes exposed heat insulating material, it is secure to keep the safety in production, no potential safety hazard; 2) exterior-wall heat insulation, architectural surface are finished simultaneously, save operation and man-hour, and reduction of erection time and engineering quantity are a kind of qualitative leaps.
Description of drawings
Fig. 1 is the structural profile schematic diagram of an embodiment of the utility model.
The specific embodiment
The utility model will be further described below in conjunction with embodiment:
Fig. 1 is the structural profile schematic diagram of an embodiment of the utility model.Among the figure, a kind of exterior-wall heat insulation, decoration integrated plate, it comprises: decoration of exterior wall cement board surface layer 1, middle insulation layer 2, cement board enhancement Layer 3, described middle insulation layer 2 is that convex-concave is joined with the mating face of decoration of exterior wall cement board surface layer 1, cement board enhancement Layer 3.Adopt convex-concave to join mainly to be the bond area of insulation layer 2 and decoration of exterior wall cement board surface layer 1, cement board enhancement Layer 3 in the middle of enlarging, its convex-concave is joined and can at right angles step-likely also can be dovetail groove shape 4.The convex-concave of present embodiment is joined and is the dovetail groove shape.The utility model further adopts following measure: in the middle of described on the insulation layer convex-concave on mating face and following mating face be symmetric arrangement or be and be arranged in parallel.These two kinds of forms all can.Decoration of exterior wall cement board surface layer 1 can adopt strengthens the glass fibre cement plate, makes versicolor cement board according to the design needs, and described middle insulation layer 2 is EPS molding foamed polystyrene board or XPS extruded plastic foam polystyrene board.All on-the-spot uncomfortable defectives of warming plate can be resolved in prefabricated factory, and construction site does not have the fire source, guarantees the safety of the on-the-spot lives and properties in building site.Described cement enhancement Layer back is provided with some back of the body bolt mounting screws hole 5, and a kind of mounting means is provided.
Above-mentioned example does not constitute restriction of the present utility model, and all employings are equal to the technical scheme that form obtained of replacement or equivalent transformation, all drop within the protection domain of the present utility model.
