The inner side of the anti-cracking protective layer is provided with the facing layer made of putty and colorful coating. The utility model has the advantages of good thermal insulating effect, strong crack resistance, material saving, high operating efficiency, etc.
Description
One. technical field
The utility model is specifically related to a kind of novel anti-crack inside heat insulation wall body, is mainly used in insulation in the external wall.
Two. background technology
At present, China's building energy consumption has accounted for 35% of national total energy consumption, and, along with constant development of economy, improving constantly of living standards of the people, the proportion of building energy consumption will further increase, and the building energy consumption of present American-European developed country has reached 40% of whole society's total energy consumption.Therefore, save building energy consumption, promotion and implementation building energy conservation work meaning is great, and is imperative.The interior heat preservation technology of body of wall.Existing a large amount of research both at home and abroad, and lot of documents is arranged:
Major technique content in these documents is:
1. the main same basic unit of interior insulation, thermal insulation layer, cracking resistance overcoat and skin coat are formed;
2. how the used heat preserving and insulating material of thermal insulation layer is formed with a polystyrene material, rock wool and thermal insulation plaster;
3. crack-resistant layer is made up of gypsum mortar and glass fiber network cloth or nonwoven.
The construction technology of original internal thermal insulated wall system places anticracking grout or other positions with grid cloth or nonwoven mostly in the construction and use of reality, the construction technology complexity, and the time-consuming material that takes is unfavorable for popularizing in an all-round way and uses.
Three. summary of the invention
The technical problem that the utility model place solves provides a kind of novel anti-crack inside heat insulation wall body.The utility model apply materials compensation, stress dispersion principle and special construction technology make this body of wall have that thermal and insulating performance is good, little, the high efficient construction of material consumption.
The utility model adopts following technical proposal to realize: a kind of novel anti-crack inside heat insulation wall body, this structure comprises basic unit's body of wall, thermal insulation layer, cracking resistance overcoat, finish coat, be provided with the multifunctional heat insulating heat insulating mortar in the inboard of basic unit's body of wall, it is the thermal insulation layer, be provided with the gypsum anticracking grout in the inboard of thermal insulation layer, be the cracking resistance overcoat, be provided with the finish coat of making by putty and color coating in the inboard of cracking resistance overcoat.Described basic unit surface of wall is cutter hair or plucking.
1. base treatment
Processing to basic unit is to prevent that the thermal insulation layer from producing one of requisite measure of " empty, drum " phenomenon.Base treatment technology is generally Surface Physical and handles and chemical treatment, the situation of apparent surface, physical treatment is partly carried out in loosening, the weathering of reply surface of wall, can use the ordinary mortar levelling to the out-of-flatness metope, bright and clean part then should be cut a hole the hair processing or the polymer cement mortar plucking is handled.
2. thermal insulation layer construction
The thermal insulation layer is respectively a composite dry powder and a polystyrene foam material to be pre-mixed also quota packing, directly mix in proportion at the construction field (site), adding water stirs, its thickness should determine that one-shot forming and levelling are adopted in the construction of thermal insulation plaster according to the coefficient of thermal conductivity and the coefficient of heat accumulation of body of wall in 4cm according to designing requirement.
3. cracking resistance overcoat construction
After the thermal insulation plaster drying (an about week), on the basis of thermal insulation plaster, smear the gypsum anticracking grout.
4. finish coat construction
After the cracking resistance overcoat drying, whitewash have flexibility, the putty of water-fast function and color coating.
Four. the beneficial effects of the utility model
1. the realization mechanism of thermal and insulating performance
Adopt granules of polystyrene: because the thermal and insulating performance of polystyrene is good, its coefficient of thermal conductivity is less: λ g=0.126w/ (mk).In this heat preserving and insulating material, dose the granules of polystyrene of some rational gradation compositions, reached the double effects that improves thermal and insulating performance and utilize solid waste.
Adopt the closed pore foaming technique: in order to eliminate the heat convection of gas in the hole, adopt miniature pore can reduce radiation heat transfer between the hole wall, thereby further improve the thermal and insulating performance of solid-state material.
Make the uniform miniature closed pore bubble that contains some in the heat preserving and insulating material: because static real gas is fabulous thermal insulation material, coefficient of thermal conductivity λ g=0.026w/ (mk) in the time of static 0 ℃, the derivative of planting heat preserving and insulating material than present name is all little, so still air is best thermal insulation material.Make the uniform miniature closed pore bubble that contains some in the heat preserving and insulating material, in solid-state heat preserving and insulating material, dosed best thermal insulation material-still air in fact exactly, can improve the thermal and insulating performance of solid material greatly.
2. the realization of the anti-cracking function of cracking resistance overcoat
Gypsum itself has good characteristics such as volume stability, high temperature resistant, good permeability, can avoid wall dewfall to occur; In addition, compare with cement, the coefficient of thermal conductivity of gypsum is lower and with insulation layer better compatibility is arranged.
Compare with existing interior heat preservation method, simplified construction sequence, improved efficiency, saved material usage, reduced material cost.
In whole construction course, selected for use material to have good thermal and insulating performance to guarantee walling system with thermal and insulating performance, meanwhile, by determining good process system, " empty, drum, the split " problem that has solved not only that the heat-preserving heat-insulating wall material often occurs, use this system process to construct, body of wall can satisfy the requirement of building energy conservation.Economically,, can improve efficiency of construction more than 40%, save material cost simultaneously owing to reduced work progress.
