预制T梁钢筋胎架法整体成型及吊装技术应用

Application of Integral Forming and Hoisting Technology in Prefabricated T-Beam Reinforced Steel Frame

文章主要介绍了高速公路施工中的预制T梁钢筋胎架法整体成型及吊装技术。在钢筋胎架上提前将预制T梁底腹板和顶板钢筋笼绑扎成型,再利用龙门吊整体吊装钢筋骨架到台座上就位。该施工技术提高了施工效率,同时保证了钢筋笼的绑扎精度及预应力管道的定位、安装精度。文章通过对预制T梁钢筋胎架法整体成型及吊装技术的施工过程、注意事项和效益分析,胎架法整体成型及吊装技术较常规施工工艺大大提高了T梁钢筋制作安装施工效率及工程质量。

This paper mainly introducesintegral forming and hoisting technology of prefabricated T-beam reinforced steel frame in expressway construction.Bottom web of prefabricated T-beam and reinforcing cage of the roof are tied up and formed in advance on reinforcing steel frame,and thenreinforcing steel frame is hoisted on platform by the gantry crane as a whole.The construction technology improves construction efficiency and ensures binding accuracy of steel cage and positioning and installation accuracy ofprestressing pipeline.Through construction process,notice and benefit analysis of integral forming and hoisting technology of prefabricated T-beam steel bar,integral forming and hoisting technology of frame method has greatly improved construction efficiency and engineering quality of T-beam steel bar manufacture and installation compared with the conventional construction technology.
