摘要
依托某工程预制梁厂,对其T梁构件生产质量影响因素进行了系统研究.首先基于试验最佳配合比,在广泛调阅相关文献的基础上,采取试验研究及理论计算的方法探究了恒温温度及升温速率等蒸养参数及3种不同的浇筑振捣工艺对成型后T梁测区回弹强度的影响规律;其次,在试验研究的基础上,基于显著性分析理论,运用方差分析法得到影响T梁构件生产质量的显著性因素;最后对预制T梁的蒸养制度及浇筑振捣工艺进行了调整,最终结果表明,装配式T梁采用调整后的预制方案,其生产质量得到了显著提升.
Abstract
Based on an engineering prefabricated beam factory,the factors affecting the produc-tion quality of T-beam members were systematically studied.Firstly,based on the optimum mix ratio of the test and extensive review of relevant literature,the influence of steam param-eters such as constant temperature and heating rate and three different casting vibratory processes on the resilience of the measured area of the T-beam after molding was investigated by experimental research and theoretical calculation.Secondly,based on the theory of signifi-cance analysis,the significant factors affecting the production quality of T-beam members are obtained by means of variance analysis.Finally,based on the above research,the steam ma-intenance system and the casting vibration process of the prefabricated T-beam are adjusted.The final results show that the production quality of the prefabricated T-beam has been signif-icantly improved by adopting the adjusted prefabrication scheme.
