原竹预制构件房屋设计与制造技术

Design and manufacture technology of prefabricated bamboo house

以原竹为主要原料设计与制造符合现代居住要求的预制构件房屋,内容包括毛竹的处理与设计强度计算,建筑构件的连接、模块化设计与性能测试,以及预制构件房屋的建造等。结果表明:屋架在实际使用载荷下具有足够的安全性能;墙体的抗侧承载力为0.78t,可用作1～2层住宅承重墙体。通过建设示范房屋证明利用原竹进行现代房屋的设计建造是完全可行的。

This paper introduces a design and manufacture technology of prefabricated modular bamboo house, which can meet the modern residential requirements. Firstly,Moso bamboo （ Phyllostachys pubescens） was conditioned to approximate constant mass in atmospheric conditions,then main physical-mechanical properties were tested and design stresses were calculated. After that,modular construction components including trusses and walls were assembled by using special connections and joints to combine and reinforce bamboo together. The truss was tested safe enough under specified load; lateral bearing capacity of the wall was 0. 78 t and could be used as load-bearing wall in two-storey building. Based on the experiments,a modular bamboo house was built up with the designed components. The results show that it is technically feasible to use bamboo as main materials in modern prefabricated house.
