【摘要】：我國(guó)北方寒冷地區(qū)農(nóng)村住宅大多靠結(jié)構(gòu)本身保溫,保溫隔熱性差,每年冬季采暖消耗能源巨大,約占全國(guó)建筑總能源消耗的2/5左右,因此,對(duì)適合北方寒冷地區(qū)農(nóng)村住宅的節(jié)能保溫結(jié)構(gòu)的設(shè)計(jì)與研究是非常必要的。建筑保溫與結(jié)構(gòu)一體化技術(shù)是將建筑結(jié)構(gòu)和節(jié)能保溫融為一體,具有保溫與結(jié)構(gòu)同壽命、保溫和防火性能優(yōu)良、質(zhì)量安全可靠等特點(diǎn),可以減少工程成本、提高建筑質(zhì)量和節(jié)能環(huán)保性能。本文首先對(duì)國(guó)內(nèi)外建筑保溫結(jié)構(gòu)一體化技術(shù)和保溫隔熱材料發(fā)展現(xiàn)狀進(jìn)行了概括介紹和分析。通過(guò)實(shí)地調(diào)研和文獻(xiàn)研究,了解到北方地區(qū)農(nóng)村房屋在結(jié)構(gòu)的整體性、抗震性、保溫隔熱性以及工業(yè)化發(fā)展水平方面還存在很多問(wèn)題。經(jīng)過(guò)對(duì)北方農(nóng)村住宅現(xiàn)有保溫材料、結(jié)構(gòu)型式和發(fā)展趨勢(shì)分析,課題組提出了新型預(yù)制外保溫板與砌筑墻體和預(yù)制秸稈板與混凝土板兩種保溫結(jié)構(gòu)一體化設(shè)計(jì)方案。然后選用一棟三層住宅,使用建筑熱環(huán)境模擬軟件DeST-h對(duì)該住宅分別采用兩種保溫結(jié)構(gòu)一體化方案與普通粘土磚在保溫節(jié)能性方面進(jìn)行模擬計(jì)算、對(duì)比分析,得出每年采暖能耗可降低30%左右,具有良好的熱工性能和節(jié)能減排效果。使用pkpm結(jié)構(gòu)計(jì)算軟件對(duì)兩種保溫結(jié)構(gòu)一體化體系在建筑整體受力計(jì)算分析,得出兩種方案下整體受力均滿足要求;通過(guò)使用ABAQUS有限元分析軟件對(duì)墻體承載力性能進(jìn)行計(jì)算,對(duì)拉結(jié)筋采用不同直徑和間距進(jìn)行比較分析,得出墻整體以及墻體中拉結(jié)筋、保溫層和結(jié)構(gòu)層的應(yīng)力和變形均很小,同時(shí)分布較為合理,體現(xiàn)出這兩種結(jié)構(gòu)均具有良好的結(jié)構(gòu)性能。綜上所述,這兩種保溫結(jié)構(gòu)一體化方案值得在我國(guó)嚴(yán)寒和寒冷地區(qū)推廣應(yīng)用,也可以為今后農(nóng)村住宅的設(shè)計(jì)研究提供一些思路。
[Abstract]:Most rural residential buildings in the cold areas of northern China rely on the insulation of the structure itself and poor thermal insulation. The annual energy consumption of heating in winter is huge, which accounts for about 2/5 of the total energy consumption of the construction in the whole country. It is very necessary to design and study the energy-saving and thermal insulation structure for rural residential buildings in the cold area of northern China. The integrated technology of building insulation and structure is to integrate the building structure and energy conservation and heat preservation. The utility model has the characteristics of the same life as the structure, excellent heat preservation and fire resistance, high quality, safety and reliability, and can reduce the project cost. Firstly, this paper introduces and analyzes the integrated technology of thermal insulation structure and the development status of thermal insulation materials at home and abroad, through field research and literature research. Understand that there are still many problems in the structure integrity, seismic resistance, thermal insulation and industrialization development level of rural housing in the north. Based on the analysis of the structure type and development trend, a new type of prefabricated outer insulation board and masonry wall and two integrated design schemes of prefabricated straw slab and concrete slab are put forward, and then a three-story residence is selected. In this paper, the thermal environment simulation software DeST-h is used to simulate and calculate the heat preservation and energy conservation of the residential building by adopting two kinds of thermal insulation structure integration scheme and ordinary clay brick respectively. It is concluded that the annual heating energy consumption can be reduced by about 30%, which has good thermal performance and energy saving and emission reduction effect. Using pkpm structure calculation software to calculate and analyze the two kinds of thermal insulation structure integration system in the whole building force analysis. It is concluded that the whole force under the two schemes meets the requirements. Through the use of ABAQUS finite element analysis software to calculate the bearing capacity of the wall, the different diameters and spacing of the tension bars are compared and analyzed. The stress and deformation of the insulation layer and the structure layer are very small, and the distribution is reasonable, which shows that the two structures have good structural performance. It is worth popularizing and applying in the cold and cold areas of our country, and can also provide some ideas for the design and research of rural housing in the future.
