| Abstract: | In Beijing Jinrnao Center project, unbonded prestressing technique is used in the 8.4m×8.4m equipment interlining and partial floor slabs of low-storey public building. In order to insure the unbonded prestress engineering quality, supervisor pays attentions to precontrol, construction control and engineering acceptance, especially on some key processes, such as fabrication, laying, tensioning and anchorage of unbonded prestressed steel bar, to guarantee high engineering quality. |
