近年来,我国住宅建筑已逐步形成了几种新的体系,除砖混建筑外主要有大模板建筑、混凝土中、小型砌块建筑、预制装配式大板建筑和框架轻板建筑等等。这些建筑在创造适宜的空间与环境方面达到了新的水平。但是,我国的北方,在建筑保温性能上仍存在着急待解决的课题。例如。由于结构和抗震的要求,在新的建筑体系中往往需要用钢筋混凝土作承重墙、圈梁、地梁 In recent years, China’s residential buildings have gradually formed several new systems. Except for brick and concrete buildings, there are mainly large formwork buildings, concrete middle and small block buildings, prefabricated large-scale buildings, and framed light-board buildings. These buildings have reached a new level in creating a suitable space and environment. However, in the north of China, there are still urgent issues to be solved in the building insulation performance. E.g. Due to structural and seismic requirements, reinforced concrete is often required in new building systems as load-bearing walls, ring beams, and ground beams.
