| 摘要: |
| 为了研究具有自主知识产权的预制混凝土结构钢筋连接方法,在钢筋锚固试验结论的基础上,设计制作了108个预制混凝土结构插入式预留孔灌浆钢筋搭接试件.依据搭接接头率为100%的要求确定了钢筋搭接长度,考虑钢筋直径、混凝土强度、搭接长度等不同影响因素,完成了试件的单向拉伸试验,得到了插入式预留孔灌浆钢筋搭接连接的破坏模式及各因素的影响规律,计算分析并给出合理的搭接长度.实验证明,插入式预留孔灌浆钢筋搭接方法,连接性能可靠且施工简便,适合住宅产业化下的预制混凝土结构的钢筋连接. |

| Abstract: |
| In order to study the connection method between reinforced bars of the precast concrete structure,based on research results about reinforcement anchorage experiments,108 lapping tests were completed.For the area percentage rate of the lap joints at 100%,the reinforcement lapping length was determined.According to the facts of bars diameter,concrete strength and different lapping length,some specimen simple tensile tests were completed.The failure mode and the impact law of factors about the reinforcement lapping were obtained,and the reasonable length was calculated.Through a series of tests and discussions,the plug-in filling hole for lap-joint of steel bar is a reliable connection,simply construct and suitable for precast concrete structure reinforced connection under the housing industrialization. |
