在民用住宅工程中,封闭阳台常采用实体立砖栏板上设钢窗的作法。现大多数联二阳台由于处理不好使分隔墙处的正立面栏板由上而下产生竖向或倒八字形裂缝(图1),这些裂缝的出现不仅影响建筑物的观感,还直接影响工程质量和使用功能。不向结构形式的阳台,其栏板的裂缝形式也不同, In civil residential projects, closed balconies often use solid bricks to set up steel windows. Most of the existing No. 2 Balconies have caused the vertical façade panels at the partition wall to have vertical or inverted B-shaped cracks due to poor handling (Fig. 1). These cracks not only affect the perception of the buildings, but also directly Affect project quality and use of features. Not to the structural form of the balcony, the form of the cracks in the fences are also different.
