武广铁路客运专线现浇梁膺架快速制梁施工技术

Construction Technology of Falseframe Rapid Beam Fabrication on Site in Wuhan-Guangzhou Passenger Line

针对目前铁路客运专线工期紧、现场施工环境复杂,桥梁梁部结构施工控制工期的情况,结合作者在施工现场丰富的施工经验,介绍膺架法这种并不新鲜的施工技术和施工工艺如何有效的利用到铁路客运专线现浇梁的建设中。重点对膺架基础、膺架搭设、贝雷片的拼装、模板的安装拆除等现场关键技术进行详细的叙述。特别针对困扰现场技术人员的桥梁现浇梁模板的拆除,介绍一种投资少、方便有效的工具,值得现场施工技术人员参考借鉴。

According to the situation of urgent construction period,complicated on-site construction environment,and control time limit of beam spandrel construction of railway passenger line,in connecting with the author’s rich experience on construction sites,this paper introduces how to use the falseframe method,one common construction technology,in construction of cast-in-situ beam in the railway passenger line,especially focusing on some key technologies,such as foundation of falseframe,building of falseframe,assembly of JQJ,installing and dismantling of building templates,and so on.Particularly,aiming to the troubling problem of dismantling of templates of cast-in-situ team,one convenient and effective tool with small investment is introduced for reference.
