木结构建筑在灾后重建中的应用
|
摘要
为了解决灾后重建中大量永久性建筑的建设问题,通过实验室测试和工程实例检验,提出了针对四川灾区的木结构建筑应用技术和实践示范。实测资料结果表明,四川传统木构建筑的常用围护结构(单层竹泥混合墙体)传热系数为4.59 W/(m2.K),保温隔热效果较差。而采用新工艺制作的改进木构建筑围护结构传热系数在2.1~2.3 W/(m2.K)之间,居住舒适性更好。并且,由于构造技术和施工工艺改进,新型木构建筑,抗震性能更佳,建设周期和成本也低于一般砖混结构建筑,较适于在灾后重建中应用。
In order to meet the requirements of post-disaster permanent reconstruction,this paper,based on lab tests and engineering example examination,presents the application technology of wood-structured building and its practical example for Sichuan post-quake reconstruction.According to experimental results,the heat insulation capability of the common architecture envelope structure(single-layer mixed wall structure of bamboo and soil) in Sichuan traditional wood-structured building is not satisfactory,with its heat transfer coefficient of 4.59 W/(m2·K).Using the innovative technology of increased airspace,the improved envelope structure of wood-structured building,with the lower construction cost and better heat transfer coefficient of 2.1~2.3 W/(m2·K),performs well in heat insulation and living comfortability.Moreover,due to the improvement of construction technology,the new wood-structured building is featured with better quake-proof performance,shorter construction cycle,and lower building costs,which is fit for practical use in the post-disaster reconstruction.
