【摘要】 石家庄市某多层框架结构,由于设计、施工原因,部分混凝土梁在结构主体完工后就出现了不同程度的裂缝,根据检测和计算校核结果对该楼采用了粘贴钢板、裂缝压力灌浆、悬挑梁加掖相结合的综合加固方法,保证了该楼安全使用。该楼加固设计中的构造措施和施工过程中的技术处理方法,可为相关质量问题的处理提供参考依据。更多还原

【Abstract】 Because of the design and construction, some concrete beams of a multistory frame structure in Shijiazhuang have different level cracks after major structure finishing. According to detecting and calculation result, the building is strengthened by the general method with bonded steel, pressure grouting in cracks, and haunching for cantilever beam. And the safe service of the building is assured. The construction measure of the strengthening design and the technical treatment method during construction can supply reference to the related engineering.更多还原
