Research On Cotton Straw Bale Houses Seismic Properties And The Thermal Performance

Green energy has become a new trend of the development of construction industry, the state vigorously promote energy conservation, environmental protection, new building materials.in this background, using energy-saving insulation plant straw construction of eco-building in our country gradually rise, its main raw material is wheat straw, corn stover, rice straw; Then compressed to form certain size as grass of brick wall building envelope material applied in ecosystem buildings. Research shows that plant grss bricks have good thermal and insulating performance however the cotton stalks as a architecture envelope walls rarely applied in China, the paper through the Cotton grss straw bricks wall as a filler material and wood framework of collaborative force, cotton straw brick construction requirements, thermal performance analysis, providing a theoretical basis for the promotion of cotton stalk grss bricks building. The main contents are as follows:(1) Through the quasi-static test of cotton straw as collaborative mechanical properties of the filler material and wood framework to analyze the experimental phenomena and hysteresis curves, skeleton curves, ductility and stiffness degradation. The results show that the wooden bottom separation, effective connection between them is the main brick and wood-frame seismic performance impact?(2) 121 farms in Shihezi demonstration building, connecting structure proposed measures single cotton straw bricks houses and construction technology, cotton straw construction to provide theoretical reference popularized in engineering construction.(3) Field detection method using heat flow meter transfer coefficient cotton straw bricks house wall. With extremely cold and cold region living architectural energy saving design standards relative ratio, comply with the severe cold wall heat transmission coefficient obtained Area C, cold A cold zone and zone B limit requirements, more energy savings than conventional ordinary wall materials; and calculate its thermal conductivity, verify cotton straw bricks wall can be used as self-insulation material used for the quantitative study of energy-saving effect of cotton straw brick building to provide a theoretical argument.(4) Cotton straw brick wall and indoor thermal environment using FLUENT software simulation analysis reveals that the wall temperature distribution and cotton straw of brick room temperature distribution.Through thesis research, not only add new materials and new structure forms of Countryside Residence in wall, so that the cotton straw to be reused, turning waste into wealth; and green energy. Reduce the economic burden on farmers housing, saving winter heating coal and household expenses have better theoretical significance and application value.
