本文系将北京市四层住宅建筑中常用的37cm厚的实心红砖墙,30cm厚的实心墙,24cm厚的七孔空心砖墙,大型砖砌块以及我院试生产的焦渣混凝土大型墙板和大型压轧板等六种外墙构造从其单位面积造价,采暖费用、外墙厚度对单位有效面积造价的影响,以及结构重量对基础的影响等几方面作了一些分析比较,并提出—些看法,作为选用外墙结构、材料时的参考。 This article will use the 37cm thick solid red brick wall, 30cm thick solid wall, 24cm thick seven-hole hollow brick wall, large-scale brick block, and the coke residue concrete large-scale wall board produced in our hospital. Six types of exterior wall structures, such as large-scale platens, were analyzed and compared in terms of their unit area cost, heating costs, and the influence of external wall thickness on the cost per unit area, and the impact of structural weight on the foundation. These views serve as a reference for the selection of exterior wall structures and materials.
