随着节能标准的不断提高,楼梯间的设计也进一步加强。在实践中出现了对楼梯间内外墙重复保温的情况。通过建立热平衡方程,对多层空心黏土砖砌体结构住宅楼梯间在不同热工设计条件下的耗热量进行对比分析。分析结果表明:楼梯间不采暖,仅需加强楼梯间外围护结构的保温就可以得到良好的综合效益。 With the continuous improvement of energy conservation standards, the design of staircases has been further strengthened. In practice there has been repeated insulation of the staircase inside and outside the case. By establishing the heat balance equation, the heat consumption of multi-storey hollow clay brick masonry residential staircase under different thermal design conditions are compared and analyzed. The analysis results show that the staircase is not heated, so it is only necessary to strengthen the insulation of the outer envelope of the staircase so as to obtain good comprehensive benefits.
