In some embodiments, in step sl, being pasted onto on body of wall by polymer bonding mortar by warming plate, the surrounding at every piece of warming plate back side arranges polymer bonding mortar band, and the back side of every piece of warming plate arranges and is uniformly arranged multiple polymer bonding mortar bonding cake. Thus, polymer bonding mortar band and arranging of bonding cake ensure warming plate firm pasting and effectively save raw material dosage.
In some embodiments, in step sl, the area that polymer bonding mortar is arranged at every piece of warming plate back side is more than or equal to 0.35 times of warming plate backside area. Thus ensure warming plate firm pasting premise under effectively save raw material dosage.
The invention have the benefit that the mode adopting rigid disk and this rigidity of alkali-resistant glass fibre net to add by the exterior wall heat-preserving system of the present invention flexibility combining can effectively prevent warming plate owing to being affected the irregular phenomenon of wall face of appearance by air and constructing operation, effectively strengthen heat insulation effect and service life. The construction technology step of exterior wall heat-preserving system is simple, and speed is fast, and work efficiency is high, and effect is obvious.
Accompanying drawing explanation
Fig. 1 is the structural representation of the exterior wall heat-preserving system of an embodiment of the present invention;
The warming plate back side that Fig. 2 is exterior wall heat-preserving system shown in Fig. 1 arranges polymer bonding mortar band and the schematic diagram of bonding cake.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
Fig. 1 show schematically show the exterior wall heat-preserving system according to one embodiment of the present invention.
As it is shown in figure 1, this exterior wall heat-preserving system, including body of wall 1, the lateral wall of body of wall 1 is sequentially provided with warming plate the 2, first rigid disk 3, alkali-proof glass fiber mesh the 4, second rigid disk 6 and decorative layer 5 from the inside to the outside. Warming plate 2 specifically adopts graphite polystyrene board or rock-wool heat insulation plate.
Warming plate 2 is fixed on body of wall 1 by bar for line 7. Bar for line 7 embeds in body of wall 1 through warming plate 2, and the quantity of bar for line 7 is no less than 6/m2. It is also provided with polymer bonding mortar, for the Primary Location of warming plate 2 between warming plate 2 and body of wall 1.
First rigid disk 3 and the second rigid disk 6 are steel fabric sheet. Between warming plate 2 and alkali-proof glass fiber mesh 4, being equipped with anticracking grout between alkali-proof glass fiber mesh 4 and decorative layer 5, the first rigid disk 3 and the second rigid disk 6 are respectively positioned in anticracking grout.
The construction technology of above-mentioned exterior wall heat-preserving system comprises the following steps:
S1, at body of wall 1 sticking heat-preservation plate 2, make warming plate 2 be fixed on body of wall by bar for line 7.
By polymer bonding mortar, warming plate 2 is pasted onto on body of wall 1. As in figure 2 it is shown, the surrounding at every piece of warming plate 2 back side arranges polymer bonding mortar band, the back side of every piece of warming plate 2 arranges and is uniformly arranged multiple polymer bonding mortar bonding cake.
