Description
Technical Field
The utility model relates to an outer thermal insulation engineering technical field of outer wall, concretely relates to exhaust apparatus for heat preservation outer wall surface course.
Background
In recent years, the external thermal insulation energy-saving system of the external wall is forced to be implemented due to the promotion of national reform. The exterior finish is generally coating and ceramic tile finish, and after a period of time, the external thermal insulation system of the exterior wall often appears the seepage phenomenon, the method of conventional remedy seepage is only to brush the waterproof coating outside the finish, because the living condition of people is improved constantly, in order to improve the comfort level of living, many areas and most residents use heating facilities and air conditioners, under this situation, the exterior wall because the air permeability of heat preservation, crack resistance layer, finish coat and repair use waterproof coating, etc. is poor, make the vapor in the wall difficult to get rid of, thus form indoor dewing, go mouldy. Meanwhile, the phenomenon of whitening and peeling caused by the re-emulsification of the outdoor coating and the phenomenon of falling caused by the damage of a heat preservation system due to the generation of water are also caused. Seriously affecting the living environment and the health of people and greatly reducing the service life of the interior and exterior decorations.
In addition, after the external thermal insulation engineering of the thin-plastered external wall of the expanded polystyrene board is put into use, the surface of the coating decorative layer has bubbles with different sizes, and further development can cause the external wall coating to fall off, so that the problem is frequently generated at the joint of the external wall coating and the external wall putty. Such problems are likely to occur in early spring of the second year of project delivery, most likely in the south side of buildings, with dark paints being more likely to generate bubbles than light paints.
The reason for this problem is: (1) the water content of the base layer wall body is high, and particularly, the insulation board is bonded immediately after the wall body is drenched by rain; (2) after the expanded polystyrene board is placed on the wall, the expanded polystyrene board is drenched by rain, the surface layer construction is started when the humidity of the insulation board is not reduced, and the water is sealed in the insulation layer; (3) the decorative layer has poor air permeability, and moisture can not migrate out through the coating layer. During winter and spring crossing, water vapor is soaked in the putty, the surface temperature of the paint is lower than 0 ℃ at night when the paint changes day and night, the putty containing the water vapor is frozen, and after ten freeze-thaw cycles, the putty loses strength and is pulverized, and the paint falls off. When the temperature is higher, the steam expands, so that bubbles are favored to be generated in the coating layer, and the coating decorative layer is damaged.
The commonly used preventive measures at present are: (1) the water content of newly constructed concrete and brick masonry is not more than 8%, and the construction of a heat insulation layer can be started; (2) measures should be taken to prevent the expanded polystyrene board from being drenched after the expanded polystyrene board is put on the wall, and the drenched expanded polystyrene board should be subjected to surface layer construction after the humidity drops.
