木材结构 - 胶合层压木材 - 面和边缘接缝切割试验

[中文适用范围]： 本文件规定了在制造工厂内通过在干燥和潮湿条件下裂解胶合线来评估胶合层压木材表面和边缘粘合有效性的方法。 它并不打算用于首选循环分层或块剪切的初始型式测试。 它基于的原理是，如果满足最小木材破坏百分比，则粘合强度超过底层基材的垂直于纹理的拉伸强度，因此粘合不是限制胶合木组件完整性的弱元素。 [外文原描述]： This document specifies methods of evaluating the effectiveness of glued laminated timber face and edge bonds within a manufacturing plant by cleaving of the glue line in both dry and wet conditions. It is not intended that it be used for initial type testing where cyclic delamination or block shear is preferred. It is based on the principle that, provided minimum wood failure percentages are met, then the bond strength exceeds the perpendicular to the grain tension strength of the under-lying substrate and therefore the bond is not the weak element limiting the integrity of a glulam assembly.
