某底部框架砖砌体房屋楼板裂缝原因分析及处理措施

Cause Analysis and Treatment Measures of Floor Crack in a Bottom Frame Brick Masonry Building

通过某底部框架砖砌体房屋楼板裂缝检测,楼板混凝土剩余原材料复检,楼板混凝土配合比、楼板混凝土模板支架、楼板施工荷载作用调查,楼板实体质量检测等综合结果,分析了该房屋楼板裂缝产生的主要原因,介绍了后期采用凿除楼板混凝土面层,注浆修补、植筋加固混凝土楼板裂缝的技术处理措施。对加固修补后的楼板堆载实荷检验,达到承载力要求,可为今后类似工程的施工质量预控和楼板裂缝加固处理提供参考。

Based on the detection and investigation of floor cracks in a brick masonry building with frame structure at the bottom of the building,this paper analyzes the main causes of floor cracks in the building,and introduces the technical treatment measures at the later stage.
