后浇带设计与施工的质量控制

Supervision on Quality Control of Design and Construction of Post-cast Concrete Band

通常对长度较长、面积较大且带地下室的高层板式楼宇等需按设计规范要求设置沉降或伸缩后浇带。后浇带的设计规定和要求不同,其施工做法也不尽一致,在施工前监理对后浇带的设计规定和施工质量控制要点必须有充分的认识和预见性。结合施工监理经验对后浇带的质量控制进行浅要分析,总结了设计阶段和施工阶段监理对后浇带质量控制要点。

According to requirements of design codes, the post-cast concrete band is generally designed to tolerant the settlement and expansion of high-rise building with longer and large scale basement. The construction method of post-cast band is different for the different design requirements and the supervisors should know the design requirement and construction quality control key points and make precaution measurements before construction. Based on practices of similar projects the analysis on post-cast band is carried out and the quality control key points from design phase to construction phase for supervisors are presented.
