无梁GBF管现浇混凝土空心楼板施工技术

CONSTRUCTION TECHNOLOGY OF CAST-IN-PLACE CONCRETE HOLLOW FLOOR SLAB WITH BEAMLESS GBF PIPE

无梁GBF管现浇混凝土空心楼板施工技术是国内最近几年才发展起来的结构施工新技术,尤其适用于大空间、大跨度柱网住宅和公共建筑。此类结构具有减轻自重、增加楼板刚度、提高隔声效果和降低结构造价等优点。大连中银大厦工程应用该项技术时,采用GBF管排列图、GBF管专用定位卡、焊接网片和楼板混凝土二次浇筑到顶等措施,使其应用趋于成熟。

Beamless GBF pipe cast-in-place concrete hollow floor slab, which is a new structural construction technology developed recent years in China, is particularly fit for residence and public building with big space and big span column grid. This structure has the advantages of lightening self-weight, strengthening floor slab rigidity, improving sound insulation and reducing structure cost. When applied to Dalian Zhongyin Mansion Project, measures taken were GBF pipe arrangement diagram, special clamp for GBF pipe, weld mesh and secondary concreting and so forth, making its application closer to the perfect.
