砌筑套管直埋技术在天津周大福金融中心项目中的应用

Application of Direct Embedding Technology of Masonry Casing in Tianjin CTF Financial Center Project

为避免一般工程在墙体砌筑后因机电管线安装而发生的拆改现象,天津周大福金融中心项目创新性地采用BIM技术对二次墙体进行深化,基于项目结构、机电等专业的高精度模型,可精确在墙体位置处确定所有机电专业套管的排布,进而在模型中深化墙体的圈梁、构造柱与砌块等构造,然后导出施工图进行现场备料、施工,最终实现墙体砌筑达到一墙一图、零剔凿、零拆改的目的,使工程砌筑施工整体质量一次成优。

In order to avoid the dismantle and alter after wall masonry caused by installation of mechanical and electrical pipelines in general construction,based on project structure,mechanical and electrical high-precision model, Tianjin CTF Financial Center project can be accurate in arrangement of electromechanical casing by innovatively using BIM technology in wall deepening design. In the model,the authors deepen designing the structure of the wall＇s ring beam,structure column and block,then export the construction drawings for the site preparation and construction. Finally,this paper realizes the target of building the wall without dismantle and alter,so as to make the whole quality of the masonry project better once.
