空心砌块,在南方炎热地区需要解决隔热问题,在北方寒冷地区需要解决保温问题,后者尤为重要。适用于南方地区的空心砌块不能简单地直接搬到寒冷的北方地区使用。需要进行空心砌块的保温设计与保温试验;并协同设计、施工、生产部门共同商定方案,经各方面鉴定技术上过关之后,最后定型投入生产。一、保温设计要求北京地区对于采暖的居住建筑物,在室外空气计算温度+18℃,室内空气相对湿度 Hollow blocks need to solve the heat insulation problem in the hot areas in the south, and the insulation problem needs to be solved in cold areas in the north, and the latter is particularly important. Hollow blocks suitable for use in the South cannot be simply moved directly to the cold northern regions. The thermal insulation design and thermal insulation test of the hollow blocks are required; the design, construction and production departments are jointly agreed upon and the technology is passed through all aspects of identification, and the final form is put into production. First, insulation design requirements Beijing residential buildings for heating, in the outdoor air temperature +18 °C, indoor air relative humidity
