Description
Technical field
The present invention relates to building structure, especially a kind of jointing structure and method of novel heat insulation heat insualting building are mainly used in the jointing of architectural exterior-protecting construction wall body outer wall outer heat insulation structure and handle.
Background technology
Along with the progressively implementation of China's building energy conservation relevant criterion, the development work of the novel heat insulation heat insualting building structure that some are intended to cut down the consumption of energy begins to quicken, and for adapting to China's construction work actual needs, a collection of novel heat insulation heat-insulating decorative board also emerges successively.At present, research at this class novel heat insulation heat insualting building structure jointing method is few, still be in the starting stage, the jointing method that now is applied to the novel heat insulation heat-insulating decorative board is mainly as follows: when plate seam wide during smaller or equal to 10mm, earlier with the on-the-spot cementation of fissures of polyurathamc; When seam is wider than 10mm, then the seam in pointing and wall heat insulation material identical materials; The no matter cementation of fissures or filleting, all should leave a blank in the sealing position, obturage with the sealing compound jointing.
The jointing technology of original heat-insulation decorative board on the one hand because selected materials is organic material, and weatherability is relatively poor, easily influences external insulation system application life in the use of reality; Because the surface temperature of material changes acutely, surface stress is big, easily forms early stage temperature cracking on the other hand, waterproof, hydrophobic processing are not carried out in the surface when meanwhile constructing, be easy to cause moisture to infiltrate, and then destroy the external insulation system structure, have a strong impact on heat insulating effect.
Summary of the invention
The jointing structure and the jointing method that the purpose of this invention is to provide the novel heat insulation heat insualting building of a kind of thermal insulation, water-proofing anticracking, good decorative property.
The feature of the jointing structure of described novel heat insulation and preservation building is: be provided with mortar levelling layer, thermal insulation layer, anticracking grout layer, elastic water-proof finish coat and heat-insulation decorative board layer outside basic unit's body of wall successively, the heat preserving and insulating material anticracking grout layer and the elastic water-proof finish coat that are provided with in the slit outside the thermal insulation layer, between the heat-insulation decorative board layer, with the jointing structure of thermal insulation building that a kind of thermal insulation, water-proofing anticracking good decorative property are provided, described thermal insulation layer is that identical material constitutes with the heat-insulation decorative board layer; Described anticracking grout layer comprises: polymer base cement mortar 84%～90%, and expansion agent 3%～16%, hydrophober 0.05%～0.1%, water supply volume is 0.5～0.6 times of total amount; Described elastic water-proof finish coat is 300～500% polymeric material for the elastic deformation amount.Described thermal insulation layer can adopt expanded polystyrene (EPS)/extruded polystyrene or directly connect with the polyurethane foam piece.
Beneficial effect of the present invention:
1, the realization of incubation and thermal insulation function
Thermal insulation filleting structure adopts EPS bar/XPS bar or directly uses polyurethane foam: the coefficient of thermal conductivity of selected heat insulating material is less on the one hand: λ≤0.040w/ (mk), heat preservation and insulation is good, the embedding of heat preserving and insulating material between plate can effectively improve the heat bridge problem of exterior-wall heat insulation on the other hand, improves the whole heat insulation and preservation effect of external wall heat insulation system.
2, the realization of anti-cracking function
The cracking resistance structure is introduced expansion agent: for reaching early stage zero purpose of shrinking of anticracking grout, according to the materialogy principle, utilize " ettringite bulge theory ", in material, introduce expansion agent, owing to after aquation, generate dilatancy crystal (ettringite and calcium hydroxide), increased the crystalline content in the mortar, fill or stopped up the pore seam, porosity descends greatly, produce volume expansion, produce compressive stress and compressive strain in the body, compensated all kinds of shrinkage strains, offset or partial offset corresponding tensile stress, thereby improved whole crack resistance.
Elastic water-proof decorating structure employing elastic deformation amount is 300～500% material, effectively avoids the formation of crackle.
3, the realization of water-proof function
The cracking resistance structure is introduced hydrophober: in order to reach waterproof, anti-seepage effect, according to the materialogy principle, utilize " functional group reactions mechanism ", in material, introduce silylation hydrophober, owing under the high alkalinity condition, form silanol with reactivity, silanol is carried out irreversible reaction with the hydroxyl in the cement-hydrate again, thereby makes the pore surface in the cement mortar obtain the hydrophobic effect.Mortar obtains whole hydrophobic effect under hardening state, has stronger water-resistance and lower water absorption rate simultaneously, effectively waterproof, antiseep.
The elastic water-proof decorating structure adopts polymeric material: this polymer-based material can be liquid such as mulseal, also can be solid such as rubber strip, and the hydrophobic character of itself can effectively prevent the infiltration of moisture, reaches the waterproof purpose.
