摘要
通过对木结构规格材握钉力试件进行盐溶液处理研究。结果表明,盐溶液中规格材握钉力较清水条件下力小;随着盐浓度的升高,木结构试件的表面握钉力、侧面握钉力均呈下降趋势,但在各盐度处理间差异并不显著;试件端面握钉力与表面、侧面握钉力相比,普遍较小,在不同盐浓度处理下,差异不明显,变化平缓;相同浓度的盐环境处理条件下,随着处理周期的延长,木构件握钉力性能呈先上升后下降的趋势。
This article mainly studied the effect of salinity on the nail-holding power in wood construction.The results showed that：in saline solution,the holding power of nails was smaller than that in purified water condition. With the increase of salt concentration,both of the surface and side nail-holding power of the wood specimens was decline,but the differences between salinity treatments were not significant.However,compared to the surface and side nail-holding power,the power on the edge was generally smaller and the difference was not obvious in the treatment of different salt concentrations.In the same concentration of salt environment,with the extension of the processing cycle,the holding power of nails showed an increasing first and then downward trend.
