摘　　要：对专用膨胀螺栓在烧结页岩多孔砖砌体中锚固性能的试验研究结果分析表明,虽然安装在砌体墙不同部位上的锚固力有所不同,但均能达到并略超过其产品抗拉拔力设计值,从而验证了能形成“自螺母效应”的专用膨胀螺栓在多孔砖砌体中应用的可靠性,解除了社会各界对多孔砖锚固可靠性的疑虑,有利于多孔砖的大面积推广应用。Analysis on the test results of the anchorage behavior of expansion bolt in sintered shale porous brick wall shows that though the anchoring strengths of expansion bolts are varied at different positions,they all reach or slightly exceed the design tensile value of the bolt. This thus proves the applicability of the special expansion bolt with self-bolt effect in the porous brick masonry and relieves the doubt about the reliability of the porous brick anchorage. It is beneficial to the wide application of perforated brick.
