Abstract

The utility model relates to a inside and outside heat preservation complex board of a outside wall body of building, which comprises a cement sand plasm floor1, rigid foam polyurethane insulating layer 2, polymer putty coating 3, which are arranged from inside to outside in the outside wall body of building. The utility model may keep the surface of the outside wall successive intact, achieves leaking, empty plump and falling resistance, and the utility model is characterized by little thickness, low heat conductive coefficient, and great heat preservation quality.

Description

A kind of building outer wall thermal insulating composite panel

Affiliated technical field

The utility model relates to the inside and outside thermal insulating composite panel of skin body, belongs to building material field.

Background technology

Traditional architecture beyond the region of objective existence wall insulated board 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 problems to be solved in the utility model 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 thermal insulating composite panel 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.

A kind of improvement as the utility model technology, the thickness of described cement mortar screeding layer is 3～5 millimeters, 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 wall insulating layer is 20～30 millimeters.In this thickness range, can further guarantee the fastness of this thermal insulating composite panel.

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.

Description of drawings

Cross-sectional view among Fig. 1-the utility model embodiment

The specific embodiment

Provide embodiment of the present utility model below in conjunction with accompanying drawing, be used for further specifying technical solution.

Embodiment is with reference to figure 1.Find out that by Fig. 1 the constituting of this building outer wall thermal insulating composite panel is respectively that thickness is the polymer putty coating 3 that 5 millimeters cement sand bed 1, hard-foam polyurethane insulation layer 2 that thickness is 12 millimeters and thickness are 5 millimeters from building outer wall from the inside to the outside.The directly outside the building continuous construction and installation of the inner surface of body of wall or external surface of this composite insulation boards, 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.Heat-insulating property is also very excellent.
