随着大型公共建筑、饭店、宾馆工程的增多,大跨度大厅楼盖结构的设计与施工已成为一个重要课题。我国无粘结预应力技术在大跨度楼板中的推广应用及大跨度梁等的试验应用证明,无粘结预应力大跨度结构具有施工简便、缩短工期、降低结构高度等优点,引起了建筑界的重视。 With the increase of large-scale public buildings, restaurants, and hotel projects, the design and construction of large-span hall floor structures has become an important issue. The promotion and application of unbonded prestressed technology in large-span slabs and the experimental application of long-span beams have proved that unbonded prestressed large-span structures have the advantages of easy construction, shorter construction period, lower structural height, etc. The importance attached.
