Abstract
The invention belongs to the technical field of architectural decoration, and discloses an external heat insulating system of an external wall thinly plastered with a polyphenyl plate and a construction method thereof. The external heat insulating system of the external wall thinly plastered with the polyphenyl plate comprises the polyphenyl plate, a protecting layer and a finishing coat which are arranged on the foundation wall body sequentially; a gap is reserved between two adjacent heat insulating plates; air exhaust grooves with openings towards the foundation wall body are arranged in the gaps, and the air exhaust grooves at the intersecting part of the gaps are communicated with each other; the back of the air exhaust groove is provided with a filler; and the air exhaust groove is provided with vents so that the air exhaust groove is communicated with the gap between the polyphenyl plate and the foundation wall body. The external heat insulating system of the external wall has the advantages that hydrosphere inside a building can be released to the atmosphere in time, so as to avoid vapor from condensing between the polystyrene heat insulating plate and the wall body, and between the heat insulating layer and the protecting layer; the finishing coat is effectively prevented from frothing and cracking; and the thermal performance of the external heat insulating system is ensured.
Description
Technical field
The present invention relates to external thermal insulation system and job practices thereof, relate in particular to a kind of exterior insulation system for polyphenyl plate thin plastering exterior wall and job practices thereof.
Background technology
The ratio maximum that exterior wall accounts in building external envelope structure accounts for 50% of overall floorage, and the heat waste by body of wall accounts for 25% of whole Building Heat loss, therefore, exterior wall is incubated, and is one of key that reduces building energy consumption." JGJ 44-2004 external wall outer insulation engineering rules " have stipulated following 5 kinds of external wall outer insulation ways: expansion polyphenyl plate (EPS plate) external insulating system for thinly plastered external wall, rubber powder EPS granule thermal insulation slurry external thermal insulation system, EPS plate cast-in-place concrete exterior wall outer heat preservation system, EPS steel wire net rack plate cast-in-place concrete exterior wall outer heat preservation system, mechanical fixation EPS steel wire net rack plate exterior wall external heat preservation system.Wherein preceding two kinds is that domestic present external wall outer insulation engineering adopts maximum ways.
In actual use, the steam of interior of building can be by body of wall to external diffusion, if the gas permeability of external thermal insulation system is bad, steam then can accumulate between insulation layer and the float coat, perhaps between insulation layer and body of wall, form dewfall, cause the steam condensation of heat insulation system inside, the water capacity of whole heat insulation system is increased, thereby cause certain hidden danger for the durability and the cracking resistance of external wall heat insulation system.Therefore, " JG 149-2003 expansion polyphenyl plate thinly plastered external insulation system of outer wall " regulation, the wet current density of the steam of the overcoat of external thermal insulation system and finish coat coating is necessary 〉=0.85g/ (m
2.h).The wet current density of coating steam is too low, and the lighter causes surface chromatic aberration, and weight person causes mouldy and the thermal property variation, even destruction in various degree.
Because of low price, easy construction, coating is widely used as the outer decoration of building.For the water paint facing, by rational priming paint, in be coated with and face is coated with design and prescription is adjusted, can reach the requirement of JG 149-2003 to the wet current density of steam.But for the solvent based coating facing, because the densification of solvent based coating film forming, steam can't vapor away from filming, bubble easily and destroy facing, and the variation that above-mentioned outer heat preservation system thermal property takes place.For the relatively poor water paint of gas permeability, as elastic coating, the problem that exists the solvent based coating facing to be caused equally.Compare with water paint, solvent based coating still has bigger advantage on application life and decorative effect, and as fluorocarbon coating, the general life-span is in 20 years, considerably beyond general water paint.Therefore, on external thermal insulation system, do the solvent based coating facing and still have bigger practical significance and value.For being the exterior insulation system for polyphenyl plate thin plastering exterior wall of facing with the solvent based coating, there is insoluble problem in existing way on gas permeability.
Summary of the invention

For achieving the above object, the technical solution used in the present invention is:
A kind of exterior insulation system for polyphenyl plate thin plastering exterior wall, be included in the polyphenyl plate, overcoat and the finish coat that set gradually on basic unit's body of wall, all leave the slit between the two adjacent warming plates, it is characterized in that: be provided with the air discharge duct of opening in the described slit towards basic unit's body of wall, the air discharge duct of each intersection, slit interconnects, and the back of air discharge duct is provided with filler; Air discharge duct is provided with blow vent, and air discharge duct and polyphenyl plate are connected with space between the basic unit body of wall thus.
In a kind of optimized technical scheme, also further comprise escape pipe, an end be positioned at basic unit body of wall top air discharge duct be connected, the other end is straight down.
In a kind of optimized technical scheme, be provided with a circle strip adhesive layer between described polyphenyl plate edge and basic unit's body of wall, and the blow vent that is provided with at least on a blow vent and the air discharge duct joins; Be provided with the point-like glue adhesive layer that several are centered on by this strip adhesive layer between described polyphenyl plate and basic unit's body of wall.
In a kind of optimized technical scheme, the dual-side of described air discharge duct is provided with connector, and two air discharge ducts are provided with through the connector juxtaposition in the intersection.
In a kind of optimized technical scheme, the dual-side of described air discharge duct is provided with connector; In two air discharge duct intersections, an air discharge duct is blocked on the length direction and is communicated with another air discharge duct through connector.
In a kind of optimized technical scheme,, blocked and formed connection in the longitudinal direction each other in two air discharge duct intersections.
As the present invention on the other hand, also provide a kind of exterior insulation system for polyphenyl plate thin plastering exterior wall job practices, comprising:
(1) basic unit's exterior surface of wall is carried out preliminary treatment, on the edge of the one side of polyphenyl plate, evenly smear a circle and leave the strip bonding adhesive of blow vent, in the zone that the strip bonding adhesive is enclosed, evenly smear several dots of adhesive, polyphenyl plate is pasted on basic unit's body of wall, leave the slit between each polyphenyl plate, maintenance certain hour after stickup is finished;
(2) lay air discharge duct in the slit between polyphenyl plate, the opening of air discharge duct is towards basic unit's body of wall, and the air discharge duct of intersection, slit interconnects, and the blow vent on blow vent on the air discharge duct and the strip bonding adhesive is connected;
