一种混凝土预制构件智能循环养护系统设计

Design of the Utility Model Relates to an Intelligent Circulating Maintenance System for Precast Concrete Members

国家提倡混凝土预制构件的使用,传统的混凝土自然养护方法时间长、受到外界环境气温的限制;根据混凝土的养护特性,对混凝土预制构件养护工艺进行研究,设计了一套智能循环养护系统,完成硬件设计选型,并给出软件控制方法;通过在模台下方放置加热系统以及加湿系统,并采用折叠养护罩将模台构成封闭空间,中央处理器根据采集到的温湿度,控制变频采暖炉的加热功率以及蒸汽加湿系统电磁阀的通断,实现控温控湿的功能;经过工程应用测试,升温阶段2小时内温度达到55℃,湿度达到90%;恒温阶段8小时内温度保持在46~60℃,湿度≥90%,系统取得良好的效果。

The state advocates the use of precast concrete members.The traditional natural curing method of concrete takes a long time and is limited by ambient temperature.According to the curing characteristics of concrete,the curing technology of precast concrete members is studied,and an intelligent cyclic curing system is designed,selection of hardware design is completed,and software control method is given.By placing heating system and humidifying system under the die,and using folding curing cover to form a closed space for the die.According to the collected temperature and humidity,the CPU controls the heating power of the frequency conversion heating furnace and the opening and closing of the solenoid valve of the steam humidification system,so as to realize the function of temperature and humidity control.Through the engineering application test,the system achieves good results.During the heating stage,the temperature reached 55℃in 2 hours and the humidity reaches 90%.During the constant temperature stage,the temperature was maintained at 46~60℃for 8 hours and the humidity≥90%.
