发布时间：2018-11-07 14:59
【摘要】：在连续刚构施工中的0号梁段、边跨现浇段施工时需搭设落地支架、三角托架,悬浇挂篮拼装后需对挂篮需进行预压。驸马长江大桥北岸引桥连续刚构桥,由于受地形(山区地形起伏大)及专项工程特点(墩高、施工交叉)等原因影响,施工0号梁段、边跨现浇段、挂篮预压时,使用三角托架具有更好的安全性、经济性,项目基于3方面施工考虑设计了通用性的托架,并进行了现场实施。主要探讨此种通用性托架的设计与施工方法、要点、注意事项等。
[Abstract]:In the construction of continuous rigid frame section no. 0, the side span cast-in-place section construction needs to set up the floor support, the triangle bracket, the hanging basket assembly need to carry on the pre-press to the hanging basket. The contiguous rigid frame bridge of the approach bridge on the north bank of the son-in-law Yangtze River Bridge is affected by the topography (large undulating terrain in the mountainous area) and the characteristics of the special project (pier height, construction crossing) and so on. During the construction of the No. 0 beam section, the cast-in-place section of the side span, and the pre-loading of the hanging basket, The use of triangle bracket has better safety and economy, the project is based on three aspects of construction considerations to design a universal bracket, and carried out the implementation of the site. This paper mainly discusses the design and construction method, main points and points for attention of this kind of universal bracket.
