Construction Technology Research Of Low-rise Residential Building Envelope Based On EPS Cavity Module

Low-rise residence building is an important part of residential construction in China, the total amount of construction occupies a large proportion, the proportion of building energy consumption is particularly large. Low rise residential buildings because of their own characteristics determine, facing the severe energy problem, especially in vast rural areas of China, because of the lagged concept and accept new things ability is poor, so far building energy-saving insulation in rural areas still did not receive the promotion, traditional rural residential construction for decades has not changed, resulting in poor indoor environment and building air conditioning energy consumption high, already did not adapt to the needs of today’s society and people’s living. Traditional external wall thermal insulation system of the material strength, durability and other reasons of low rise residential construction has many limitations, in China in recent years has been in advance of building insulation structural integration technology, gave birth to the many products. EPS cavity module system through the development and application of some foreign countries companies, the introduction of enterprise in our country, and carries on the localization of the floor, but for the application of new products is not specific standards of practice, now mainly used in the rural areas and construction way arbitrarily irregular fan, resulting in thermal insulation performance is not up to the desired effect and material waste. Having lots of construction experience and detailed product information, how to combine the relevant building codes and standards, is used to analyze and design the node of the construction, the problems that need to be solved in the new building materials and promotion system.Based in Dongying City, Shandong Province, the HaiRong new material company EPS module products, based on national building codes and standards, construction experience and product characteristics of EPS hollow block shear wall of low rise residential structural nodes of in-depth study, summary and analysis of the EPS hollow cavity module products and structural requirements of architectural design and construction example of were analysis. Article is divided into six chapters:Chapter one is the introduction part, the domestic construction insulation structure integration of research and application are described, the EPS module products are introduced, the research contents and methods of this thesis etc. are introduced. The second chapter mainly introduces the EPS cavity wall module of low rise residential system characteristics, including the type of EPS module products, application system as well as the wall performance test; the third chapter from the building of the foundation, wall, floor, roof, stairs, fireproof construction, pre buried pipeline and decoration and other aspects of EPS module cavity shear wall system architecture nodes for the research and design. The fifth chapter through one EPS cavity wall module low layer building projects were introduced and analyzed, including the system size of building design, building construction, building indoor thermal environment test, indoor annual temperature and heat load simulation calculation, construction than ordinary wall without insulation construction of economic (cost recovery period). Taking the architecture characteristics as the basis, draw a few sets of typical low rise residential level, provide a useful reference to the construction and promotion of the standard EPS cavity wall module of low rise housing, specification.
