某砖结构房屋在验收过程中,发现位于伸缩缝两侧的第1层墙体和顶板存在裂缝。通过计算分析,该结构基底反力的差异较大,产生地基不均匀沉降,从而在局部墙体产生较大的剪应力,造成墙体及局部楼板开裂。本文分析了裂缝产生的原因,讨论了裂缝对结构的危害,提出了相应的修复措施,以供设计参考。 During the inspection and acceptance process of a brick-structured house, there was a crack in the first layer of the wall and roof on both sides of the expansion joint. Through calculation and analysis, the difference in base reaction force of the structure is large, resulting in uneven foundation settlement, resulting in a larger shear stress in the local wall, resulting in cracking of the wall and the local floor. This paper analyzes the causes of cracks, discusses the damage of cracks to structures, and proposes corresponding repair measures for design reference.
