摘要
通过无粘结预应力混凝土空心楼板施工实践,从预应力筋敷设、混凝土浇注、后张拉及锚固封堵等环节探讨若干质量问题,并对照相关规程规定逐一分析原因,提出可行的预防措施及补救方案,为类似工程施工积累经验。
By way of construction practice,the paper analyses the reason and put forward practicable precautions and remedial scheme one by one according to related standards about quality problems on laying of unbonded tendon^placing concrete.expanding unbonded tendon 、 sealing the end etc,so that we can accumulate a wealth of experience for similar engineering.
