摘要：胶合木是我国梁柱式、井干式木结构建筑的主要材料。介绍我国胶合木应用现状,分析层板分等、指接工艺和胶合工艺对层板及胶合木力学性能的影响,阐述各主体制备工艺目前存在的问题及发展趋势。在此基础上,分析胶合木梁抗弯承载性能和破坏模式,探讨布状、棒状和板状增强方式对胶合木的增强机制,总结各种增强方式的作用效果和不足,为胶合木的进一步研究提出建议。
Glued laminated timber(GLT)is a main material for beam-column timber structures and log houses in China.In this paper,the current status of GLT industry in China was elaborated.The effects of the key manufacturing process of GLT including the laminate grading,finger-joining process,and gluing process on the mechanical properties of GLT were analyzed.The existing challenges and developing trends of the main manufacturing processes were described.Based on the practical situation,the bending properties and failure modes of GLT were analyzed,and the reinforcement mechanisms of cloth-like,rodlike,and plate-like reinforcement on the GLT were discussed.The benefits and deficiencies of the reinforcement technologies were summarized.
