Description
Technical field
The utility model relates to external wall heat-insulation plate for external and corresponding external wall outer insulation structure thereof.Specifically, be the warming plate external wall outer insulation structure that is used to replace the foamed plastics external wall outer insulation.
Background technology
Building energy conservation is a fundamental state policy of China, and it requires building must carry out the space enclosing structure insulation, to reduce warming and cooling in summer energy consumption.Wherein, external wall outer insulation is the emphasis of building heat preservation.But up to now, the extensive external wall outer insulation method that adopts of China all is outer subsides or plug-in foamed plastics based on the polyphenyl foam plate.Adopt foamed plastics to carry out external wall outer insulation and exposed three big serious problems: one, because foamed plastics is inflammable, initiation fire very easily, and Hong combustion property is strong, and smog is big, toxicity is big, death by suffocation rate height, even adopt the flame retardant type foamed plastics, still can not avoid fire, resemble super-huge fire such as encircling the building fire in CCTV's building annex fire, China Science and Technology Hall's new shop fire, the Olympic Sports Center, Jinan fire, the Nanjing, all cause by foamed plastics.Input insulation on the net and fire can search 410,000 relevant informations, the seriousness of visible foam plastics initiation fire; Its two, hollowing comes off.Because foamed plastics is organic material, body of wall is an inorganic material, and the two interface is in conjunction with bad, if adopt polymer mortar to paste, the foam insulation hollowing incident that comes off often takes place; Its three because foamed plastics is easily aging, the design life of China is up to 25 years, this means 25 years will overhaul once insulation layer, not only serious to the building infringement, and produce a large amount of rubbish, and strengthen the accumulative total cost of building heat preservation.
Foam concrete is the inorganic heat insulation material that rises in recent years, and it is made by cement foamed, does not fire fully, and insulation approaches foamed plastics, and the energy-absorbing antidetonation, sound-absorbing sound insulation, and the operating period is more than 60 years, substantially with the same life-span of building.Therefore, foam concrete is the best regeneration product of foamed plastics in the building heat preservation of generally acknowledging both at home and abroad, also is the developing direction of building heat preservation.
As everyone knows, the heat insulation effect that directly is incubated of exterior wall is best.It not only has protective effect to agent structure, reduces ambient temperature directly to the influence of body of wall, the cold and hot bridge of favourable elimination, and favourable body of wall cool-storage in summer and accumulation of heat in winter.It is a kind of very good building thermal insulation material that the foam concrete plate is used for external wall outer insulation, but its difficult point is sheet material fixing at wall face.Because the thermal conductivity ratio foamed plastics of foam concrete is higher (be used for external wall outer insulation and be generally 0.05～0.07w/mk), so thickness of slab is big, and (be generally 30～150mm), density (to be used for external wall outer insulation and to be generally 150～300kg/m greatly in addition
3), just make its surface density also bigger, if finish coat is arranged, its surface density is bigger.Simultaneously, since foam concrete porosity height, intensity difference, and low to the adhesion strength of metope, this just makes it very difficult fixing of metope.If adopt the method for bonding, be difficult to cement, action of gravity causes bigger bearing down, also makes its bonding operation be difficult for carrying out, when particularly breadth is big.If adopt the method for fixture anchoring, then because the foam concrete quality is loose, and relatively poor to the bond stress of crab-bolt, selfweight stress concentrates on crab-bolt, be easy to make foam concrete to destroy, crab-bolt is loosening, and warming plate is peeled off under blast.
Just because of the problems referred to above, China's foam concrete warming plate does not so far obtain extensive use in external wall outer insulation, have only the minute quantity small-sized do not have veneer products adopt method of attaching to be used for external wall outer insulation (general requirements is 200 * 200mm, 250 * 250mm), then carries out the construction of polymer cement crack-resistant layer and finish coat.The shortcoming that adopts this small-sized not have veneer products is to need to adopt earlier thin the plastering of cracking resistance grid cloth to carry out surfacing, carries out the finish coat construction again, and construction complexity and speed are slow, have improved the insulation cost.As a whole, also there are not desirable foam concrete external wall outer insulation goods to release and use at present both at home and abroad.
The utility model content
The purpose of this utility model is exactly to solve the problem that above-mentioned external wall is incubated existence outward, and several foam concrete Outwall thermal insulation boards are provided, and corresponding external wall outer insulation structure.
Foam concrete warming plate that the utility model proposes and external wall outer insulation thereof are configured with two kinds, that is: facing small-sized warming plate and paste structure, big specification warming plate of facing and anchoring thereof the structure that combines with stickup.
The specification of facing small-sized warming plate is 200 * 200mm, or 250 * 250mm, or 300 * 300mm, and its structure is density 150kg/m
3～250kg/m
3Foam concrete basic unit and finish coat on it.Finish coat can be the polychromy concrete, also can be the following stone material of thickness 3mm, or ceramic tile, or aluminium-plastic panel.This warming plate external wall outer insulation is made up of warming plate, adhesive mortar layer, body of wall for pasting structure, and the adhesive mortar layer is bonded as one warming plate and body of wall.
The standard specification of the big specification warming plate of facing is 1200mm * 600mm.
The big specification warming plate of facing type structure is: on the foam concrete insulation layer, be compounded with the polychromy surface layer; Its finish coat can be the polychromy concrete, also can be that thickness is the following stone material of 3mm, or ceramic tile, or aluminium-plastic panel, or metal sheet.Embeded nut is arranged in the warming plate, and nut has bolt to match.For making things convenient for stacking of warming plate, bolt just screws in nut at warming plate fixedly the time to metope.
The external wall outer insulation that the stickup that facing thermal insulation board adopted combines with anchoring is constructed by warming plate, adhesive mortar layer, Embeded nut in the anchor bolt, plate, and the anchor hole on the metope is formed.Bolt is anchored at warming plate on the metope by Embeded nut in the plate and the anchor hole on the metope.Between warming plate and metope, add screed in addition, cooperate anchorage effect, make warming plate fixing more firm on metope.
The beneficial effects of the utility model are:
(1) the small-sized facing thermal insulation board is because specification is little, and drying shrinkage stress is difficult for concentrating, and brickwork joint is not easy to crack, and it is little to conduct oneself with dignity, and easily pastes.Moreover because foam concrete porous surface and mortar are combined, it is that Pasting is firm that the small-sized product does not need polymer mortar.In addition, finish coat has been protected foam concrete basic unit, has prolonged the application life of product.
(2) big specification facing thermal insulation board adopts anchoring and the technology path of pasting dual fail-safe, insulation layer is combined with metope firmly, obscission can not appear, even meet with the influence of strong wind and cold and hot temperature, the danger that does not also have warming plate to come off, overcome that existing foam concrete plate is only sticking not to be hung, the deficiency of poor stability can be mounted on metope with the foam concrete warming plate than large format (as 1200 * 600mm specification commonly used etc.).
