自1996年以来,先后参与设计了几幢高层住宅,其结构形式均是钢筋混凝土剪力墙体系,住宅的外墙一般是200mm～250mm 厚的钢筋混凝土墙,依据《民用建筑节能设计标准》(JN26-95)第一期节能要求,上述墙体均需做保温设计,将采暖能耗控制在规定的水平。在此以前,太原地区的住宅外墙保温多用于多层住宅局部,措施简单,一般内侧抹水泥珍珠岩砂浆。高层住宅大面积的外墙保温还未有实例。从热工性能上讲,外墙外保温要优于内保温,可减少热桥,提高墙体内壁表面温度,减少对人体辐射,改善热舒适条件。然而,在当时,缺乏外墙外保温的施工经验,调研北京地区的一些外墙外保温实例均不是很理想,不同程度地存在外墙裂缝
Since 1996, it has participated in the design of several high-rise residential buildings whose structural forms are all reinforced concrete shear wall systems. The external walls of residential buildings are generally 200mm to 250mm thick reinforced concrete walls, based on the “Civil Building Energy Efficiency Design Standards” ( JN26-95) The first phase of energy-saving requirements, the above-mentioned walls need to do insulation design, control heating energy consumption at the required level. Prior to this, the outer wall insulation of residential buildings in the Taiyuan area was mostly used in multi-storey residential buildings. The measures were simple, and the inner surface was generally covered with cement-perlite mortar. There are no examples of high-rise residential exterior wall insulation. From the thermal performance point of view, the external wall insulation is better than the internal insulation, can reduce the thermal bridge, increase the wall surface temperature of the wall, reduce radiation to the human body, improve the thermal comfort conditions. However, at the time, there was a lack of experience in the construction of external insulation of the external walls. It was not very ideal for investigating some examples of exterior insulation of the external walls in the Beijing area. There were cracks in the external walls to varying degrees.
