高强预应力砼新技术是建设部“八五”期间重点科技推广应用项目,福建省已在各种建筑工程中得到了广泛的应用。 1.工业厂房20个工程中,大型构件采用高强钢丝配筋已超过1000榀,其中:18～24m屋架890榀,10～75吨级吊车梁94榀,12m托架32榀; 2.多层多跨框架结构工程12项,高强预应力配筋的梁段达200个以上,梁跨在14～21m范围内,大多是2～4层框架。其中层数最多的是福州立达大厦14层的扁梁,跨度最多的是福州福华纺织有限公司的四跨连续梁;
The new high-strength prestressed concrete technology is a key technology popularization and application project during the “8th Five-Year Plan” period of the Ministry of Construction. Fujian Province has been widely used in various construction projects. 1. In 20 projects of industrial plants, the use of high-strength steel wire reinforcement for large-scale components has exceeded 1,000 榀, including 890 18 for 18~24m trusses, 94 榀 for cranes of 10~75 metric tons, and 32 12 for 12m cradle; There are 12 multi-span frame structures, with more than 200 high-strength pre-stressed beam sections and beam spans ranging from 14 to 21 m, mostly 2 to 4 layers. Among them, the most numerous layer is the flat beam of the 14th floor of Lida Building in Fuzhou. The most span is the four-span continuous beam of Fuzhou Fuhua Textile Co., Ltd.;
