Prevention&Treatment Of The Moisture In Timber-Structure Folk Dwellings Of Tujia Minority In Southwest Hubei

The research on Chinese traditional folk dwellings is always being ofconcern,especially in the condition of globalization,while local techniques are fadingaway.Most researches of folk dwelling are based on design theory and historicalinterpretation,while this article attempts to illustrate the methods of construction andrepair technology in Timber-Structure Folk Dwellings of Tujia Minority in SouthwestHubei,with the point of prevention and treatment of moisture.This paper primarily focuses on the root causes and solutions of the problem in sixparts as follows.ChapterⅠ,which aiming at building a clear and complete background for the latterchapters, gives a brief introduction of the research object, aim, significance, researchmethods and the present research status home and abroad.ChapterⅡ explained the concept of moisture，moisture-proof types and the basicmeasures in principle, and also summarize all sorts of practices on moisture-proof oftraditional buildings in general,which provides the theoretical support for the laterchapters;ChapterⅢ illustrated the presence of moisture environment. in southwest Hubeiwith the view of settlement geography.At the same time through field investigation,itconcludes the harm,characterizations and types of different parts of the building itself,damp issues raised;Chapter IV summarized the moisture-proof methods from three levels,takingtypical villages Qingyang dam and Peng village for example: architectural design level,construction and technical level self-compensation level. One architectural design level,itdescribed its moisture-proof strategy through village layout, street design relations andmonomer scale; On technical level it summarized the moisture-proof technique on load-bearing structure and skin structure; independent compensation focuses primarily onon spontaneous ventilation and moisture-proof heating means;Chapter V described the moisture principle and appearance of wood pillar,therelationships of percentage of moisture,height of wood pillar and compression strengthaccording to the observation experiment of moisture and concentrated load compressivestrength experiment of wood pillar.Also it discussed with the regular roles,trying to get amethod to justify the danger of traditional timber-structure dwellings just by observationand measuring the percentage of moisture of wood.Chapter VI questioned the regulations and norms and called for the significance ofestablishing a simple and easy operation of strength specifications on the traditionaltimber-structure building.
