Description
Technical field
The present invention relates to waterproof and the moisture-proof dosing technology field of architectural exterior-protecting construction, is a kind of moistureproof impervious structure of back side of architecture indoor body of wall simple in structure specifically.
Background technology
The peripheral structure body of wall of China's building construction is generally to be formed by the two-sided composite mortar leveling layers of masonry such as common brick, sand lime brick or air-entrained concrete building block, insulation layer and architectural surface structure.What the leveling mortar of interior outer wall body generally adopted is that common 32.5 portland cements and quartz sand mix together in 1:2.5 ratio; Insulation layer generally adopts perlite or kervit microbead insulated sand slurry, and northern area also adopts the ways such as the compound anticracking grout linked network of polyphenyl plate; Outer decorative layer material is mainly coating, stone material or ceramic tile etc.; The material of interior trim layer is mainly coating, wallpaper, wall cloth and dalle etc.
The building material coefficient of thermal conductivity difference of all kinds of building external envelope structure bodies of wall is very large, and coefficient of thermal expansion is also different, and consequent thermal stresses is just different.If the coefficient of thermal conductivity of gas concrete is 0.11-0.18W/ (m.K), the coefficient of thermal conductivity of sand lime brick is 0.528W/ (m.K), and mortar heat conductivity coefficient is 0.93W/ (m.K), and concrete coefficient of thermal conductivity is 1.74W/ (m.K); Because the ringing of thermal stresses affects the wall crazing of the exterior wall causing, and then cause the Seepage of external wall body of wall more and more general, become at present China's many ground Common Quality Fault In The Construction Project.Because the back side of external wall body of wall is not generally taked waterproof or moisture-proof structure, and then cause the decorative layer on architecture indoor surface to occur the phenomenons such as burn into comes off or goes mouldy, have a strong impact on the normal use in house.
In the metope of architecture indoor space enclosing structure, the waterproofing course inefficacy seepage that the body of wall upstream face of kitchen, washroom is done, will cause its body of wall retaining, and then occurs seepage at its back side; The body of wall position of closing on balcony, window is because of the water supply and sewerage pipeline of laying under rain leakage and the terrace water source factors such as seepage of breaking, because terrace and Cement for walls are plastered as the loose microcellular structure of hydrophilic, moisture is rapid diffusion under capillary and siphonage, all there will be the body of wall phenomenon of making moist at each position of indoor wall space enclosing structure.Once body of wall makes moist, wall body surface decorative layer, as the wood materials of coating and use, as doorframe, fitment etc., after also can making moist because of body of wall, cause mouldy, be out of shape and grow termite etc., thereby affect its application life.If can need moistureproof position to take preventive measures in advance to building interior space enclosing structure, will extend finishing life cycle, cut the waste.
In the national standard and technical specification of Chinese architecture construction at present and decorations, in architectural exterior-protecting construction, just the upstream face at exterior wall upstream face, roofing and kitchen and toilet has carried out waterproof or moistureproof processing, and on other architectural exterior-protecting construction surface, all do not take any waterproof and moisture preventive measure and structure, architectural surface is attached directly on concrete or cement mortar substrate layer, once wall leakage and channeling water, the architectural surface being attached on substrate layer will be by water destruct.
As can be seen here, on the substrate layer of space enclosing structure, set up the damp-proof coating structure of one safety, environmental protection, the water or the steam that deaden in body of wall permeate to architectural surface, to effectively avoid water or the destruction of steam to architectural surface in body of wall, this is the current technical issues that need to address in this area.
Summary of the invention
In view of this, the object of this invention is to provide on the substrate layer that a kind of plaster of cement in architecture indoor space enclosing structure or concrete surface are firm and brush one or more layers inorganic scale aqueous epoxide resin paint, form damp-proof coating one, water or steam separate layer together with decorative layer is formed with between substrate layer, play moistureproof impervious effect.
