首都“前三门”统建高层住宅工程全面推广了大模板建筑体系。在冬季施工中,我公司一工区第一施工队初次采用了液化石油气红外线辐射器养护混凝土墙板的新技术,取得了较好的效果。国外在六十年代后期,已开始在建筑工程中应用红外线加热养护混凝土。国内目前大都用于干燥、烘烤、整型、退火等工艺及局部采暖,建筑施工方面的应用尚不多见。通过几个月的实践,我们体会到这一养护工艺 The “Three First Doors” of the capital’s high-rise residential building project has comprehensively promoted the large formwork construction system. In the winter construction, the first construction team of the company’s first working area adopted the new technology of liquefied petroleum gas infrared radiators to protect concrete wall panels, and achieved good results. In the late 1960s, the use of infrared heating to protect concrete had begun in construction projects. Most of the current domestic use for drying, baking, molding, annealing and other processes and local heating, construction applications are still rare. After a few months of practice, we realized this curing process
