Research And Application In Liaoning Hang Assembling-Heat Preservation Wall

In the building development system of our country,the exterior wall part of the building plays an extremely important role.Among them,the main role is embodied in the functional aspects of the envelope and the external wall itself.At present,the building exterior wall system commonly used in our country is mainly composed of concrete block or shear wall,and exterior wall insulation material is composed of insulation structure.The outer wall structure of shear wall is not often used in ordinary buildings because of its high cost and cumbersome construction process.Due to the high water absorption rate of aerated concrete,mortar is easy to lose water too quickly when masonry,which reduces the strength of concrete block external wall system,and then produces some common quality problems.Moreover,the efficiency of aerated concrete masonry construction is low,at the same time,it needs a lot of manpower cost,and the masonry surface itself will appear a large deviation,so it needs to be leveled out.At the end of the construction,there will be a large amount of construction waste,which is not in line with the principles of saving water and saving materials,and it also does not accord with the requirements of developing green buildings.At present,the exterior wall system of concrete block used in Liaoning Province usually adds a layer of insulation layer to the exterior wall.The difference between this layer of insulation technology and the location of the geographical region has a certain relationship.This insulation layer also carries thermal insulation,sound insulation,waterproof,fire-proof and other properties.Therefore,for the construction industry of our country,the urgent problem to be solved is to develop the exterior wall system which is suitable for the present construction,and at the same time,we can make a remarkable improvement in the diversified performance of the building industry.This paper is divided into five parts,the first part is the introduction,mainly on the source of the subject and the purpose and significance of the research,the domestic and foreign research status of insulation wall,the content and research methods of the subject;The second part is the analysis of the current situation of the insulation wall in Liaoning,this part mainly introduces the adhesive external wall insulation technology,the thermal insulation technology system of the exterior wall coated with heat insulation paste and so on.And introduced the material of the wall selection,for the wall structure form research,mainly divides into the wall exterior insulation structure form,the wall interior insulation structure form,the exterior wall sandwich heat preservation and the exterior wall self-insulation system,the third part of this paper the key point,This paper mainly studies the self-insulating wall,and analyzes the material use and construction form of the self-insulating wall.The fourth part is the application of Liaoning hanging and assembling self-insulating wall,and analyzes the convenience of production and installation of hanging and assembling wall.At the same time,the paper analyzes the design of the thermal insulation structure in the exterior wall system and the research on the anti-crack measures of the exterior wall in the construction.The fifth part is the conclusion,which is the summary of the content of the paper.
