摘要
对结构工程加固中广泛应用的构件锚固连接技术进行了系统的试验研究 ,试验主要包括双根化学粘结锚杆在若干典型情况下的锚固性能 ,得到了不同锚固深度和不同锚固间距对双根粘结锚杆锚固性能的影响 ,结果表明当锚固间距大于 2 0 0mm时 ,可以不考虑单筋锚固强度的降低 ,当锚固间距小于 2 0 0mm时 ,应适当考虑间距对锚固强度降低的影响 .文中提出的双根粘结锚杆的锚固强度设计建议值 。
Members joints of post_embedding adhesive anchors applied widely to structure engineering strengthening were studied systematically by experiments, which including the testing of strengthening performance of typical diameters, depths and spans for double post_embedding adhesive anchors; that the different depths and spans how effect on the performance of anchors are obtained. All of the testing results show that the pulled_up loads of adhesive anchors do not be considered to lose if the span between two anchors is greater than 200 mm, the performance is similar to the single anchor does. However, the performance decrease should be token account for if the span between two anchors is smaller than 200 mm. The suggested strength values for post_embedding double adhesive anchors can provide some references to the design of anchor groups in structure strengthening engineering.
