通过115个试件的拉拔试验,研究了埋置于混凝土块体中带锚固板钢筋的机械锚固强度,分析了埋入深度、保护层厚度、箍筋配置、混凝土强度和钢筋直径等因素对带锚固板钢筋机械锚固强度的影响,并与传统的带90°弯折钢筋的锚固性能试验进行了比较。试验结果表明:推广带锚固板钢筋,用规格合适的钢筋锚固板取代带90°弯折钢筋的弯折延伸段是可行的,是可以实现相同或更好的锚固强度的。
The mechanical anchoring strength of anchoring plate embedded in concrete block was studied by the pullout test of 115 specimens. The effects of embedding depth, thickness of protective layer, stirrup configuration, concrete strength and steel bar diameter on The mechanical anchorage strength of anchorage-bar reinforcement is compared with that of conventional anchorage performance test of 90-degree-bent reinforcement. The experimental results show that it is feasible to extend the flexure with anchorage plate and to replace the flexural extension with 90 ° flexure with the appropriate specification of anchorage plate, which can achieve the same or better anchorage strength.
