提出一种焊接预留孔钢筋浆锚搭接连接技术,通过对36个钢筋浆锚搭接连接试件的拉拔试验,研究其破坏形态、荷载-试件变形曲线以及裂缝发展过程等。试验中,33个试件为钢筋拉断破坏,3个搭接长度为0.3ll的试件发生了锚固破坏,且锚固破坏的试件出现了纵向贯穿劈裂裂缝。研究表明:该连接方式性能良好,可显著减小钢筋搭接长度。 This paper presents a technique of lap-anchor connection of rebar with welded reserved holes. The failure mode, the deformation curve of load-specimen and the development process of fracture are studied through the pull-out test of 36 rebar lap joints. In the experiment, 33 specimens were broken by the steel bar, and the specimens with three overlap lengths of 0.311 were damaged by anchorage, and the specimens damaged by anchorage appeared longitudinally through the splitting cracks. The research shows that the performance of the connection method is good, which can significantly reduce the lap length.
