Description

The gas concrete self-heat preservation heat insulation wall

Technical field

The utility model relates to a kind of gas concrete self-heat preservation heat insulation wall, is particularly suitable for doing the non-bearing exterior wall.

Background technology

Aerated concrete wall mainly is made up of air-entrained concrete building block, concrete beam and concrete column.Because air-entrained concrete building block has light weight, self thermal resistance is big, has the self-heat preservation heat insulation characteristics, and can save clay solid brick, more and more receives publicity in builing industry in recent years.But, because beam and column with concrete for making, the building block material made from gas concrete is different, so the concrete beam and column is easy to form the heat bridge of body of wall, and be easy to crack at the intersection of body of wall and beam or post, thereby influence the heat insulation effect of air-entrained concrete building block, also can produce the infiltration phenomenon.In addition, with the air-entrained concrete building block masonry panel and in during exterior rendering,, be easy to produce defect such as cracking, hollowing, efflorescence if use conventional cement mortar to body of wall.Above-mentioned disadvantages affect applying of air-entrained concrete building block.

Summary of the invention

The purpose of this utility model is, a kind of gas concrete self-heat preservation heat insulation wall is provided, and this wall body structure is simple, has the self-heat preservation heat insulation effect, the integral heat insulation stable performance.

Realize the technical scheme of the utility model purpose: a kind of gas concrete self-heat preservation heat insulation wall, it has concrete beam, concrete column, the masonry that has air-entrained concrete building block to build by laying bricks or stones therebetween, have between air-entrained concrete building block the pre-buried of level or after the reinforcing bar of planting,

A, on the outer surface of beam and column, articulamentum, insulation layer, topping and finish coat are arranged from inside to outside successively;

B, at the outer surface of masonry the polymer plastering mortar layer that contains the tertiary carbon acetate structure is arranged, the finish coat material of its outer finish coat and above-mentioned beam and column is identical and fuse;

C, the bottom that the fuses bottom with brushing gypsum is arranged at the inner surface of beam, post and masonry, the skin coat of surface layer with brushing gypsum arranged on it;

Masonry mortar layer between d, air-entrained concrete building block is the masonry mortar layer that is mixed with water-loss reducer;

Described topping is to press the pure-acrylic emulsion screed be embedded with mesh sheets, its mesh sheets to surpass seam 150mm at least between beam or post and masonry, and its mesh sheets that surpasses seam portion is pressed in the plastering mortar layer that is embedded in the masonry outside.

The insulation layer of above-mentioned body of wall is the polystyrene particle composite thermal insulation material, and its articulamentum is the concrete interface agent layer; Perhaps described insulation layer is a polyphenyl plate, and its articulamentum is the polyphenyl plate bond layer.

The mesh sheets of above-mentioned body of wall is the alkali-resistant glass fibre grid cloth, or galvanized steel wire netting.

The finish coat of above-mentioned body of wall is to be made of with the elastic coating layer with flexible waterproof putty layer and exterior wall exterior wall; Or constitute with the face brick layer by adhesive layer and exterior wall, the mesh sheets of the topping of adhesive layer inboard is a galvanized steel wire netting and by burying in topping and to pass the crab-bolt and the body of wall base material of galvanized steel wire netting, insulation layer and articulamentum affixed.

Technique effect of the present utility model: body of wall of the present utility model, have following three advantages: one, outer surface at the concrete beam and column has the described articulamentum of technical solutions of the utility model, insulation layer, topping and finish coat from inside to outside successively, so eliminated the heat bridge that produces because of concrete beam, post and aerated concrete masonry material difference, guaranteed the insulation and the effect of heat insulation of aerated concrete wall integral body of the present utility model; They are two years old, in the aerated concrete masonry part, several special-purpose motars and the supporting use of masonry mortar have been adopted, be that outer surface has the polymer plastering mortar layer that contains the tertiary carbon acetate structure, the brushing gypsum layer that the masonry inner surface has bottom to use, the brushing gypsum skin coat that has surface layer to use on it, build by laying bricks or stones with the masonry mortar that is mixed with water-loss reducer, the overall performance that can guarantee masonry like this is stable, can cracking, hollowing and efflorescence, the intrinsic self-heat preservation heat insulation performance of building block itself is not fully exerted, and layer of structure is simple, easy construction; They are three years old; the mesh sheets of burying of pressing can be disperseed stress in the topping in the beam and column outside; so overcome because of ambient temperature and humidity change the material deformation, the coating cracking that cause, shortcoming such as seep water, come off, and then prevented that the aerated concrete wall self-heat conserving lost efficacy.Simultaneously, mesh sheets surpasses the seam of concrete beam or post and aerated concrete masonry, has solved seam crossing again and has produced because of material is different that shrinkage strain differs phenomenon such as the crackle that caused, infiltration and the problem of the heat insulating effect decline that causes thus.Therefore, body of wall of the present utility model not only made full use of the big characteristics of gas concrete self thermal resistance and also the integral heat insulation heat-proof quality stable.
