Construction method of large silo dome concrete
The invention relates to the field of building construction, in particular to a construction method of large silo dome concrete. The large silo dome concrete comprises the following steps: 1) when a silo wall is constructed to an elevation, pre-burying a plurality of pull rings at a certain distance from the lower part of a top beam of the silo wall, and mounting steel suspension cables on the pull rings, so that all the steel suspension cables are arranged into a steel cable net in a criss-cross manner; 2) prefabricating a central net rack and a fan-shaped net rack; 3) hoisting and fixing thecentral net rack and the fan-shaped net rack on the steel cable net; 4) erecting formwork supporting scaffolds on the net racks; 5) measuring downwarp amount of the steel cable net after performing pre-compaction for a period of time based on weight of cast-in-situ reinforced concrete at a silo dome, and adjusting stretching height of a supporting vertical rod based on the downwarp amount after dismantling; 6) erecting a dome formwork; (7) pouring dome concrete; and (8) disassembling a steel pipe supporting frame and the dome formwork. According to the construction method, the construction efficiency is greatly improved, the construction period is shortened, and the construction cost is lowered.
本发明涉及建筑施工领域，具体是一种大型筒仓穹顶砼的施工方法，包括以下步骤：1）当仓壁施工到标高时，在距离仓壁顶梁下方一定距离处预埋一圈若干个拉环，在拉环上安装钢悬索，使所有钢悬索纵横交错布置成钢索网；2）预制中心网架和扇形网架；3）将中心网架和扇形网架吊装到钢索网上并固定；4）在网架上搭设模板支撑脚手架；5）按筒仓穹顶现浇钢筋砼的重量预压一段时间后测量钢索网的下挠量，卸载后根据下扰量调整支撑立杆的伸出高度；6）支设穹顶模板；7）浇筑穹顶砼；8）拆除钢管支撑架和穹顶模板；本发明施工效率大大提高，缩短了工期，降低了施工成本。
