摘要

CLT所指的新型木质建筑材料需要对各种连接类型的强度进行准确的评估。由于有可能在工厂中创建快速安装和刚性连接，因此使用粘接钢棒的CLT面板连接很有趣。由于CLT在相邻层中具有垂直方向板的结构，因此粘贴杆的强度和性能难以预测。本研究的目的是通过在clt面板的横截面中相对于板层的不同位置进行拉拔试验来确定粘接杆的强度。在无间隙和应力消除的5层CLT试样中，所有考虑的钢棒直径均小于木板厚30mm。采用双组份环氧胶粘剂体系锚固杆长均为100 mm。

STRENGTH ANALYSIS OF GLUED-IN STEEL RODS WITH DIFFERENT LOCATIONS IN CLT PANELS CROSS SECTION

New types of wood based building materials to which the CLT refers require an accurate evaluation of the strength of varioustypes of connections. CLT panels connections with glued-in steel rods are of interest due to the possibility of creating quickmounted and rigid joints in the factory. Since the CLT have the structure of the perpendicular orientated boards in adjacentlayers, the strength and behaviour of the pasted rods is difficult to predict. The purpose of this study was to establish thestrength of the glued-in rods by pull-pull tests with different locations relative to the boards layers in the cross-section of theCLT panel. Diameter of all considered steel rods was smaller than thick of timber planks 30 mm in 5-lyers CLT specimenswithout gaps and stress relieves. Anchored length of rods in all specimens was 100 mm by using two component epoxy adhesive system.
