Description of drawings
Fig. 1 is the structural representation of Cast-in-situs type heat-preserving wall of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail, but not as to restriction of the present utility model.
As shown in Figure 1, the Cast-in-situs type heat-preserving wall of an embodiment of the present utility model, comprise exterior wall protected apron 2 and the insulation layer between exterior wall protected apron 21 to establishing, insulation layer 1 has the foam cement layer of bubble for the inside that forms with exterior wall protected apron 2 bondings after being solidified by cast-in-place foam cement slurry.As shown in Figure 1, the inside of foam cement layer has a lot of bubbles, therefore has heat insulation effect preferably, but because there is bubble inside, fluid loss is big if it solidifies maintenance processes, easily cause be full of cracks, the exterior wall protected apron 2 higher and that play the effect that prevents the moisture excessive evaporation of therefore need gaining in strength in its outside.In addition, after moulding, exterior wall protected apron 2 also plays the inner foam cement layer effect of protection, prevents that it is subjected to the erosion of external environment.
As shown in Figure 1, as preferably, the exterior wall protected apron 2 in the present embodiment is magnesite polyphenyl composite plate, and described magnesite polyphenyl composite plate comprises internal layer and polyphenyl plate 21 and outer field magnesia glass fibre plate 22 foam cement slurry bonding.Polyphenyl plate 21 quality are light and soft, have fabulous insulation and cracking resistance, and polyphenyl plate 21 all has fabulous caking property with magnesite slurry and the foam cement slurry of magnesia glass fibre plate 22, magnesia glass fibre plate 22 has higher intensity, two kinds of materials that are difficult for bonding have not only well bondd, and because the polyphenyl plate quality is light and soft, avoided the different issuable crackings with the foam cement coefficient of expansion of magnesia glass fibre plate, increased the heat insulation effect of body of wall simultaneously.According to the difference in the geographical position of building, the thickness of insulation layer 1 can be selected between 20cm-50cm, is generally 30cm.Be to be raw material with 32.5# or 42.5# Portland cement as the foam cement layer of insulation layer 1, add the foaming slurry and stir and solidify back formation foam cement through foaming machine.Foam cement has light weight, and heat-insulating property is fabulous, cheap advantage.But its intensity is lower, and is easy to the output segmentation crack, thereby as body of wall, its surface must be carried out linked network and be smeared sclerosis, cracking resistance processing such as cement mortar.Because through foaming, the foam cement layer after the curing contains a lot of bubbles, so the density of foam cement layer is at 300kg/m
