北京市基建指挥部组织北京市第二建筑公司、国家建委建研院、北京市建研所等单位,在201工程中试验采用了煤气红外线养护混凝土的新工艺,从去年11月至今年2月的冬季施工过程中,用这种方法完成了2万平米的高层住宅建筑。煤气红外线养护是采用液化石油气为燃料,在装有液化气的缸上用分气管接通各辐射器,所用的辐射器按单体的发热量不同而有几种型号,在工程中经常使用的是发热量为9000大卡/小时的1号辐射器。在一块进深5.1米,高2.8米的钢模板上附加一个保温套,在内部
The Beijing Infrastructure Command organized the Beijing No. 2 Construction Company, the State Construction and Construction Commission, the Beijing Institute of Construction and other units. In the 201st project, a new process of gas infrared curing concrete was tested, from November last year to February of this year. In the winter construction process, 20,000 square meters of high-rise residential buildings were completed in this way. Infrared gas maintenance uses liquefied petroleum gas as fuel. The radiators are connected to the radiators on the cylinders equipped with liquefied gas. There are several types of radiators used according to the calorific value of the monomers. They are often used in the project. The No. 1 radiator with a calorific value of 9,000 kcal/hour. Attach an insulation sleeve to a steel template 5.1 meters deep and 2.8 meters high, inside
