Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, the utility model provides a thin outer wall insulation construction that plasters of polyphenyl board aims at solving the existing thin outer wall insulation construction that plasters of polyphenyl board and coheres insecurely, the problem that heat preservation performance reduces, and specific characteristic is as follows:
a thin outer wall insulation structure that plasters of polyphenyl board, including the basic unit wall body 1, polystyrene cystosepiment 2, anti-crack layer 3 and finish coat 4 that connect in order.
The anti-cracking layer 3 comprises a first anti-cracking surface layer 301 positioned on the inner side and a second anti-cracking surface layer 302 positioned on the outer side, a hot galvanizing electric welding net 303 is arranged between the first anti-cracking surface layer 301 and the second anti-cracking surface layer 302, and the hot galvanizing electric welding net 303 ensures that the veneer layer 4, particularly the veneer layer made of face bricks, is tightly connected with the inner wall. And the hot galvanizing electric welding net 303, the first anti-cracking surface layer 301, the polystyrene foam board 2 and the base layer wall body 1 are fixedly connected through the fixing device 5.
The inner side surface of the polystyrene foam board 2 is provided with a plurality of square grooves 201 along the horizontal direction. And a vitrified micro bubble heat preservation mortar layer 6 is sprayed on the inner side of the polystyrene foam board 2.
The advantages of this approach are: during construction, the polystyrene foam board 2 can be integrally formed by the vitrified microsphere thermal mortar layer 6 sprayed on the surface of the base layer wall body 1, and the friction force between the polystyrene foam board and the base layer wall body is improved by the square grooves 201. The polystyrene foam board 2 can be combined with a wall body into a whole after the form is removed, the construction is easy to operate, and the construction can be carried out as usual even in winter.
One of the characteristics of this insulation construction lies in: the fixing device 5 prefabricated inside the base layer wall body 1 is adopted to strengthen the structural stability. Specifically, the method comprises the following steps:
the fixing device 5 comprises an embedded part 501 arranged inside the base layer wall body 1, a threaded pipe 502 with threads arranged inside is arranged on the embedded part 501, a pressing cap 503 is screwed on the threaded pipe 502, and the pressing cap 503 is pressed on the outer side of the hot galvanizing electric welding net 303. The fixing device 5 is preferably made of plastic, so that the weight of the wall surface can be reduced, and the stability is improved.
Common mode is generally through the plastics crab-bolt with polystyrene foam board 2 fix on basic unit's wall body 1, but this kind of mode exists fixed insecure, produces the problem that drops easily for a long time, utilizes pre-buried built-in fitting 501 in basic unit's wall body 1, sets up built-in fitting 501 simultaneously when pouring basic unit's wall body 1, can improve the stability of wall surface layer. Preferably, the number of the fixing devices 5 per square meter is not less than three, and the length of the screwed pipe 502 inserted into the wall of the base wall 1 is not less than 50mm, so as to improve the stability of the wall surface.
The second characteristic of the heat preservation structure is that: the bonding structure adopts the modified vitrified micro bubble thermal insulation mortar with the same thermal insulation performance, and the thermal insulation effect is strengthened. Specifically, the method comprises the following steps:
the vitrified micro bubble heat preservation mortar layer 6 is a combination of vitrified micro bubbles and heat preservation concrete, wherein the vitrified micro bubbles comprise aluminum powder, a water reducing agent and a phase change material additive. The vitrified micro bubbles are prepared from vitreous lava ore sand through processes of expansion, vitrification and the like, have a vitrified closed surface, have a porous cavity structure inside, are irregular spherical inorganic particle materials, can play a role of hollow sand and solid air entraining agent in buildings, serve as novel inorganic heat-insulating materials, and have been better applied to the field of building energy conservation in recent years. However, the traditional vitrified micro bubbles have the defects of low vitrification rate, low closed pore rate, high water absorption rate, fragility and the like, and the heat insulation effect of the vitrified micro bubbles and products thereof is seriously influenced. Therefore, the performance of the glass bead is improved by adding additives such as aluminum powder, a water reducing agent and the like into the traditional glass bead. The vitrified micro bubble heat preservation mortar layer 6 has the super-strong high temperature resistance functions of heat preservation, sound absorption and absorption of decorative harmful gas. The polystyrene foam board 2 is sprayed to the inner side of the polystyrene foam board 2 through a spraying machine conveying pipe by utilizing a foaming spraying process, so that the heat preservation function is enhanced, the polystyrene foam board can serve as a bonding layer, the polystyrene foam board 2 is bonded with the inner side material, and the polystyrene foam board is prevented from falling off.
