Abstract
A composite insulating layer for exposed wall of building is constructed through plastering a (3-5)-mm cement mortar layer on the surface of wall, spraying a (12-17)-mm foam polyurethane layer, and coating a (5-8)-mm polymer putty layer.
Description
Affiliated technical field
The present invention relates to the construction technology of inside and outside insulating composite layer and this kind insulating composite layer of skin body, belong to building thermal insulation material and technology field.
Background technology
The construction of traditional architecture beyond the region of objective existence wall insulating layer mainly is that polystyrene thermal insulation plate is fixed on the skin body, carries out external surface again and decorate to handle, and such insulation measure piece is more, than being easier to face checking to occur, coming off and the phenomenon of hollowing.For guaranteeing the lower coefficient of thermal conductivity of insulation layer, the thickness of this insulation layer is also bigger, is generally 30 millimeter in addition, and during heat preservation construction, it was bigger to take the interior space in therefore especially externally body of wall carried out.
Summary of the invention
The technical problem to be solved in the present invention is, the problem at prior art exists designs a kind of outer surface of wall continuous whole that makes, not easy to crack, come off, the building outer wall insulating composite layer of hollowing.Simultaneously, the thickness of this insulation layer is little, and coefficient of thermal conductivity is lower.
For solving the technical scheme that the technical problem proposed takes is that constituting of this building outer wall thermal insulating composite panel is respectively cement sand bed 1, hard-foam polyurethane insulation layer 2, polymer putty coating 3 from building outer wall from the inside to the outside.For guaranteeing its performance, the thickness of described cement mortar screeding layer should be 3～5 millimeters, and the thickness of hard-foam polyurethane insulation layer is 12～17 millimeters, and the polymer putty coating layer thickness is 5～8 millimeters, and the thickness of whole heat insulating layer of outer wall is 20～30 millimeters.In this thickness range, can further guarantee the fastness of this thermal insulating composite panel.
Its construction technology is, at first in the levelling of external wall surface water silt particle slurry, its thickness is 3～5 millimeters, now sprays 12～17 millimeters hard-foam polyurethane insulation layer then, in the pitted skin external surface blade coating polymer putty coating of this insulation layer, its thickness is 5～8 millimeters afterwards.
As a kind of improvement of the technology of the present invention, insulation when carrying out this kind construction in to external wall, to the insulating composite layer of interior wall and exterior wall junction and each floor plate and exterior wall junction respectively at least 300 millimeters of interior wall and the extensions of floor place.Can effectively solve the heat bridge problem of this position, two places like this.
Because of this composite heat-insulating layer can be directly outside the building surface of wall construct continuously, do not install and need not carry out prefabricated chunk, guaranteed the continuous whole of building outer wall insulation layer, cracking resistances that simultaneously outermost polymer putty coating 3 itself is had and the certain extensibility that is had also can make phenomenons such as this warming plate is not prone to cracking, comes off, hollowing.In addition, the thermal and insulating performance of the excellence that the hard-foam polyurethane insulation layer has itself, its coefficient of thermal conductivity is 0.022, therefore, uses this kind material as insulation layer, only needs 12～17 millimeters thickness can meet the building heat preservation standard.
