胶合空心木柱结构设计与制造工艺

Structural Design and Manufacturing Process of Glued Hollow Wooden Columns

胶合木结构建筑中,柱作为轴心受压构件,需要对其承载能力进行强度和稳定性验算。对空心柱进行理论设计计算,从而确定一定尺寸、规格下柱能承受的最大载荷。由于没有专用设备进行实验论证,本研究仅对不同规格的空心木柱和实心木柱进行对比,得出了在保证空心木柱强度与实心木柱相当时,空心木柱的外围直径与实心木柱相比均有一定程度扩大的结论,从而使胶合木结构中的胶合木柱达到了美观与结构的双向要求。同时提供了几种具体空心木柱的外观设计。

In the construction of glued wooden structures,it is necessary to calculate the strength and stability involved in the bearing capacity of columns, as axial compression members. The theoretical design and calculation of hollow columns can help determine a certain size, specification and maximum load of columns. Due to the lack of complete equipment for experimental demonstration, the study simply compares the hollow wooden columns and solid wooden columns of different sizes ,with the conclusion obtained that when it is guaranteed that the strength of hollow wooden columns is equivalent to that of solid wooden columns, the outer diameter of hollow wooden columns is expanded to a certain degree, compared with solid wooden columns,thereby making the glued wooden columns in glued wooden structures meet the bidirectional requirements for beautiful ap pearance and structure. At the same time, cross-sectional appearance design of several kinds of hollow wooden columns are provided.
