Abstract

The invention discloses a heat insulation wall with energy saving and the construction method. The heat insulation wall comprises an inner wall, a middle wall and an outer wall. Inner and outer walls are set by foam concrete prefabricated bricks with E-shape section and higher intensity. The middle wall, which is cast in case, is the foam concrete self-heat insulation wall with good heat insulation performance. The invention also contains the construction of said heat insulation wall. The structure of invention is simple and cool-hot bridge can not be generated. It is provided with good heat insulation performance and there is no need to build another outer wall to reserve heat. Not only the cost is saved but also standards of environmental protection and energy saving can be guaranteed. Compared the heat insulation wall constituted by clay wall and outer heat insulation wall, the cost can be saved more than 30%.

Description

A kind of energy-saving heat preservation thermally insulated wall and job practices thereof

Technical field

The present invention relates to a kind of energy-saving heat preservation thermally insulated wall and job practices thereof, especially relate to a kind of energy-saving and thermal insulating foam concrete body of wall and job practices thereof.

Background technology

At present, whole nation skin has the body of wall more than 60% still using solid clay brick or structural clay tile approximately, having caused ploughs reduces, and the deterioration of the ecological environment is more because the loam brick thermal and insulating performance is relatively poor, be built into 240mm thick wall body (coefficient of thermal conductivity 0.58) with structural clay tile, energy consumption is big, reach energy conservation standard, also needs to do insulating layer of external wall with the thick polystyrene foam plastics of 40mm (coefficient of thermal conductivity 0.042), and only should brush exterior wall coating material on this insulation layer, and should not paste exterior wall tile.

Be development energy-saving building thing, various light heat-insulating novel wall materials arise at the historic moment.But up to now, all there is certain defective in disclosed various heat-preserving heat-insulating wall material.As No. 94112087.2 disclosed foaming plastic ceramic coals ash light wall materials of Chinese patent, 99116095.9 number disclosed light wall material, 200310111249.1 number disclosed is the cast-in-situ wall material of primary raw material preparation with building waste mixture or gangue, 200410021951.3 disclosed multifunctional inorganic foam materials for wall, the primary raw material that adopts all is that flyash or gangue are or/and other discarded objects, thereby raw material are limited to, and process still needs consumes energy etc., causes cost higher; Some difficulty of construction is also bigger.Chinese patent discloses a kind of foam concrete light block for No. 01237175.0, and it comprises is used to the cuboid concrete Hollow brick building block of leading to up and down, is filled with foam concrete at Hollow brick building block inner chamber.02272771.X number disclose the compound solid wall plate of a kind of high strength, it is made up of GRC hollow wall panel and core bar or glass fiber reinforced cement concrete and core bar, and described core bar is made up of sulphate aluminium cement light weight aggregate concrete or sulphate aluminium cement foam concrete.Above-mentioned various material volume is big, builds difficulty by laying bricks or stones; The material heat insulation effect because of masonry mortar produces cold and hot bridge have a greatly reduced quality.Add that also must do insulating layer of external wall just can reach the national environmental protection energy conservation standard, further strengthened building costs, it is bigger therefore to apply resistance.200420080498.9 number disclose a kind of gas concrete self-heat preservation heat insulation wall, though its heat insulating effect is better, structure is quite complicated, it is bigger to apply difficulty.200420064726.3 also there is same defective in number disclosed external heat preservation heat insulation wall.200510047439.0 the preparation method of number disclosed foaming concrete lightweight wall material in situ, use hydrogen peroxide and aluminium powder to make blowing agent, the cost height, and hydrogen peroxide is a kind of strong oxidizer, can bring very big potential safety hazard to construction, need constructing under the condition more than 20 ℃ in addition, also can bring inconvenience to construction.

Summary of the invention

The objective of the invention is to overcome the above-mentioned defective of prior art, a kind of good effect of heat insulation is provided, raw material sources are extensive, and are simple in structure, build by laying bricks or stones easy, lower-cost thermal insulation foam concrete wall and job practices thereof.

The objective of the invention is to be achieved through the following technical solutions:

The present invention's heat-preserving heat-insulating wall is made of interior body of wall, middle body of wall, outer body of wall three parts, body of wall and outer body of wall are to build the body of wall that forms by section by laying bricks or stones for the foam concrete blockwork of " E " shape in described, and middle body of wall is the foam concrete insulation layer that on-the-spot monobloc cast forms; Described foam concrete blockwork is provided with foam concrete spray mouth.

Described foam concrete blockwork spray mouth preferably is located at blockwork top.

Described foam concrete blockwork should be selected the big slightly and higher foam concrete manufacturing of intensity of coefficient of thermal conductivity for use; The described middle body of wall of mainly making insulation layer then should select for use the good foam concrete spray of heat-insulating property to build.

Heat-preserving heat-insulating wall job practices of the present invention may further comprise the steps: (1) is that " E " shape and the foam concrete blockwork that is provided with foam concrete spray mouth are built into interior body of wall, outer body of wall by laying bricks or stones with section; (2) heat insulation effect is good foam concrete adopts spray technology to go between interior body of wall and the outer body of wall by the foam concrete spray mouth spray of blockwork, form the middle body of wall that fuses with inside and outside body of wall inboard, finally formed the self-heat preservation heat insulation wall of the effect of going along with sb. to guard him.

The double template of building insulation layer of doing of external and internal wall that the present invention builds by laying bricks or stones with " E " shape foam concrete blockwork, casting craft is simple; Wall body structure is simple and don't produce cold and hot bridge, high insulating effect, and body of wall of the present invention (coefficient of thermal conductivity 0.11～0.19, adjustable) will reach the same heat insulation effect of above-mentioned structural clay tile, and thickness of wall body only needs 200mm to get final product (coefficient of thermal conductivity gets 0.15); Needn't do external thermal insulation in addition, both save cost, guarantee that again environmental protection and energy saving are up to standard, and can do any decoration of exterior wall.The economy aspect, the present invention saves cost more than 30% than the heat-preserving wall that is made of structural clay tile and clay solid brick and external thermal insulation.
