石河子地区冬季采暖建筑，室内外温差在30℃以上。室内外温度因为对流、传导、辐射等发生变化。特别是保温性能不同的材料，用在房屋同一构件中．因为它们的导热系数不同，在应用了保温性能差的材料的部位上，往往容易产生“冷桥”。在楼层局部悬挑的房屋中，如果钢筋混凝土楼 Shihezi district winter heating buildings, indoor and outdoor temperature difference is above 30 °C. Indoor and outdoor temperatures change due to convection, conduction, and radiation. In particular, materials with different insulation properties are used in the same component of the house. Because of their different thermal conductivities, “cold bridges” tend to occur at locations where materials with poor thermal insulation properties are used. In a partially overhanging house on the floor, if the reinforced concrete building
