广州荣庆大厦有粘结预应力平板的设计与施工

广州荣庆大厦楼盖结构中采用的有粘结预应力平板，在设计理论，施工工艺，锚固体系及经济效益方面均有一定优势。由于预应力筋长度较短，锚具回缩引起的损失较大，帮适当提高了σｃｏｎ。为不影响主立面美观，张拉端均为内埋式。有粘结板的预应力筋采用集束布置，束间距较大，因此铺设工序较为简单。

DESIGN AND CONSTRUCTION OF A BOND PRESTRESSEDFLOOR SLAB SYSTEM OF THE GUANGZHOU RONGQING MANSION PROJECT

A bond prestressed floor slab system has been adopted forthe GuangZhou Rongqing mansion floor construction. It has the followingadvantages, namely: 1, a good design 2, an easy construction technology 3, areliable prestressed anchorage system and 4, a rich benefit. Because itslength of prestressed reinforcement is rather short and its loss caused byshrinkage of anchorage is rather heavy, therefore, its has been dulyincreased. In order to make an attractive and beautiful elevation view, allthe prestressing ends are well embeded and concealed. All bond prestressedreinforcements are heavily concentrated, therefore, each of their spacing isspaced rather widely apart, thus, their procedures of construction are rathersimple and easy.
