【目的】近年来,随着国家在节能减排方面的要求提高,以及大力倡导使用新型绿色材料,木材作为一种传统绿色环保的建材逐渐受到人们的青睐。正交胶合木(CLT)板是近年来兴起的一种建造现代木结构建筑的新型构件,具有良好的整体性、稳定性以及较高的强度。为了研究组坯方式对正交胶合木(CLT)双向板的弯曲性能,本研究采用2种组坯方式(三层交叉和四层交叉)制作了2组厚度相同的胶合木双向板试件,研究其静力弯曲性能。【方法】用于制作试件的原材料为兴安落叶松板材与聚氨酯结构胶粘剂,制作2组、每组2个共4个正交胶合木双向板试件,通过千斤顶在板的跨中施加单点集中荷载,同时测试和分析应变、挠度和极限...

【Objective】In recent years, with the improvement of national requirements on building materials in energy conservation and emission reduction, and the vigorous promotion of the use of new green materials, wood, as a traditional green and environment-friendly building materials, has been increasingly paid attention to, cross laminated timber board is a new type of component used to construct modern timber structure buildings. It has good integrity, stability and high strength. In order to study the influence of assembly pattern on the bending ...
