现浇钢筋混凝土空心楼盖气囊式芯模安装施工

Construction Method of Air Bag Core Mould for Cast-in-situ Reinforced Concrete Hollow Floor

文章对贵州省贵阳市花溪区中铁城·锦溪项目2#地下车库芯模安装施工工艺进行总结,结构形式为现浇钢筋混凝土框架结构,楼盖形式采用现浇钢筋混凝土空心楼盖。芯模安装施工工艺流程如下:①绑扎墙柱钢筋、搭设模板支架并安装模板;②对暗梁及肋梁位置进行放线;③安装抗浮件;④绑扎柱帽钢筋、暗梁、框架梁、肋梁钢筋;⑤捆绑扎带;⑥绑扎板底钢筋;⑦安放下层楼板厚度定位件;⑧安放芯模并以扎带及铁扣固定;⑨绑扎板面钢筋及柱帽面筋与拉结筋;⑩安放上层楼板厚度定位件;?混凝土浇筑及养护。本施工工艺流程经过在本工程中多次实践与完善,已经具备了较为成熟的施工技术可行性。

In this paper, the construction technology of the 2# underground garage core mould of Jinxi project in Huaxi District of Guizhou city in Guiyang province was summarized, and the structure was cast in place reinforced concrete frame stxucture.the core mold installation construction process is as follows ： Lashing wall column reinforced, erection the template bracket and install the template;for beam and rib beam position line; the installation of anti floating;the lashing column cap beam,steel beam,reinforced rib;the binding belt; the binding reinforcement;the thickness of the floor slab placed lower positioning parts; the mandrel and tie to put belt and hasp fixed;to tie plate Bar and column caps and Rachel gluten ribs;the upper placed slab thickness positioning parts; concrete pouring and cuiing.The construction process has been in practice and improved in the project,has a more mature construction technology feasibility.
