Dumbbell-shaped concrete-filled steel tube arch rib and construction method thereof
The invention provides a dumbbell-shaped concrete-filled steel tube arch rib which comprises an upper circular steel tube and a lower circular steel tube which are arranged in parallel, concrete fillsthe upper circular steel tube and the lower circular steel tube, and a straight web in the middle and arc-shaped webs with two concave sides are connected between the upper circular steel tube and the lower circular steel tube to form a left abdominal cavity and a right abdominal cavity. Abdominal cavities are filled with concrete. According to the dumbbell-shaped concrete filled steel tube archrib and the construction method thereof, the structure is reasonable, the stress performance is good, building construction is easy and convenient, and the problems that in existing dumbbell-shaped concrete filled steel tube construction, a web plate explodes, and pressure pouring cannot be adopted for concrete in the abdominal cavities can be solved.
本发明提供一种哑铃型钢管混凝土拱肋，包括两根平行设置的上圆钢管和下圆钢管，所述上圆钢管和下圆钢管内均填充有混凝土，在上圆钢管和下圆钢管之间连接有中间的直腹板和两侧内凹的弧形腹板，形成左右两个腹腔，腹腔内均填充有混凝土。本发明提供一种哑铃型钢管混凝土拱肋及其施工方法，其结构合理且受力性能好、建造施工简便，能解决目前哑铃型钢管混凝土施工中腹板爆仓、腹腔内混凝土不能采用压力灌注等问题。
