金属齿板与木材连接强度的研究

Study on Connection Strength of Timber with Toothed Sheet-steel Plate

参照我国《木结构试验方法》国家标准(GB/T 50329-2002)和《木结构设计规范》国家标准(GB 50005-2003),研究不同方向的金属齿板钉入木材时的受剪极限承载力。试验结果表明,使用连接角度为0°的金属齿板连接方法时,受剪极限承载力较好。落叶松木材的受剪极限承载力高于SPF木材。

With reference to standard for methods testing of timber structures（ GB/T 50329 -2002） and standard for code for design of timber structures （ GB 50005 - 2003 ）, the ultimate shear capacity of wood was researched when toothed sheet-steel plate in different directions were thwacked into wood. The results showed that the ultimate shear capacity of wood was better when the e connecting angle for connecting toothed sheet-steel plate was 0°. The ultimate shear capacity of larch was higher than SPF wood.
