砌体结构出现裂缝和产生变形对建筑物的危害主要表现在结构安全性和房屋使用功能两个方面,砌体结构裂缝的出现预示着结构承栽力可能不足,让人们没有安全感,贯穿性裂缝的形成会降低结构的整体稳定性和抗震性能。外墙、楼板和屋面结构裂缝会影响结构防水,造成房屋渗漏,明显的结构裂缝或较大的变形会影响建筑物的美观。 Masonry structure cracks and deformation of buildings on the main hazards in the structure and housing functions in two aspects, the emergence of cracks in the masonry structure indicates that the structure bearing capacity may be insufficient to make people feel insecure, penetrating Crack formation will reduce the overall structural stability and seismic performance. Exterior wall, floor and roof cracks will affect the structural waterproof structure, resulting in housing leakage, the obvious structural cracks or larger deformation will affect the appearance of the building.
