东北严寒地区农村住宅稻草制品墙体构造技术研究

A study on the construction technics of strawbale walls in severe cold rural areas of northeast China

东北农村是我国主要的农业生产基地,稻草资源十分丰富,多数农村都以燃烧的方式处理秸秆,既浪费资源,又造成空气污染,严重影响居民的身心健康.研究稻草制品墙体不仅可以促进可再生农作物的循环利用,降低因焚烧秸秆对环境的污染,而且有利于农村建筑的节能减排,对于推进农村绿色建筑发展、改善生态环境具有重要意义,有广泛的社会效益和环境效益.论文系统研究了稻草在东北农村住宅墙体中的应用技术,提出三种可行的构造技术方案,并针对可能出现的问题与弊病进行了深入分析,给出相应的对策.研究成果分别应用于三项示范工程中,经测试:示范住宅墙体热阻为传统砖墙的2倍以上,保温节能效果明显,各方面性能良好,受到广大农户的欢迎.

Rural areas in Northeast China is the national major agricultural production base, where the straw resources are very rich. Straw often burned after harvest in most rural areas, which causes considerable resources wastes and air pollution, and even seriously influences people＇s physical and mental health. Research on strawbale walls may not only promote the recycling of crops remaining, but also reduce the pollution from straw combustion. Moreover, it helps the rural building energy conservation and emission reduction, thus significantly promoting rural green building development, as well as improving ecological environment and delivering widespread social efficiency and environmental benefit. This article systematically studies straw＇s applied technology in northeast rural housing walls. Three feasible structural technics are proposed, each with thorough analysis and corresponding countermeasure towards a wide range of potential issues. The results of the research are applied separately in three demonstration projects, and the test reveals that the thermal resistance of demonstration wall is over twice as much as that of the traditional brick wall, which verifies the obvious effects of heat preservation and energy conservation; with fine performance in all aspects; the wall is popular among farmers.
