摘要
圆筒形单板层积材(简称圆筒LVL)是一种新型木质工程材料,它是以螺旋缠绕的方式将单板加工成交错层积的构造,从而抑制弹性模量的下降。圆筒LVL具有很好的力学性能和优良的工程性能,可广泛应用于建筑等领域。本文就圆筒LVL的制造方法、研究状况、特点及用途等进行了较为详细的归纳总结。
Cylindrical laminated veneer lumber (LVL) is a new type of structural wood composites. A spiral winding method has been used in the manufacture of cylindrical LVL with helical interlocked grain. The interlocked grain can minimize the reduction of young's modulus. Cylindrical LVL has excellent mechanical properties and engineering performance. It can be used in both residential and commercial applications. This paper summarized the manufacture methods, previous studies, structural features and applications of cylindrical LVL.
