多层砖房通常会发生开裂现象,特别是北方地区,气候干燥,年温差大,房屋建成后一年,有的二、三年,甚至更长一段时间后,墙体产生裂缝,它影响了建筑的功能和美观,严重的导致结构安全度降低,抗震性能差。因此防止砖墙开裂十分重要,但裂缝产生的原因较复杂,下面就各种裂缝的状态、产生,处理及预防措施作一概述。 Cracks often occur in multi-storey brick houses, especially in the northern part of the country, where the climate is dry and the annual temperature difference is very large. Cracks occur in the walls after a year, some two, three or even a long time after the houses are built, The function and aesthetics of the building result in a serious decrease of structural safety and poor seismic performance. Therefore, it is very important to prevent the cracking of the brick wall, but the reasons for the cracks are complicated. The following gives an overview of the status of various cracks, their production, handling and preventive measures.
