Dumbbell-shaped concrete filled steel tube arch rib structure using corrugated steel web
The invention discloses a dumbbell-shaped concrete-filled steel tube arch rib structure which comprises an arch rib, the arch rib comprises an upper circular steel tube and a lower circular steel tube, the upper circular steel tube and the lower circular steel tube are connected through the corrugated steel web in a welded mode, and a suspender anchoring point is arranged at the top of the upper edge or the bottom of the lower edge of the arch rib. The anchoring point of the suspender and the arch rib upper edge suspender is a bearing plate, the anchoring point of the suspender and the arch rib lower edge suspender is an anchoring plate, and concrete is arranged in the upper circular steel pipe and the lower circular steel pipe. The construction method comprises the following steps: 1) prefabricating the arch ribs; 2) hoisting an arch rib; and 3) pouring concrete. Compared with the prior art, the structure has the advantages that the structure is clear, construction is convenient, the corrugated steel web is used for connecting the upper circular steel pipe and the lower circular steel pipe of the dumbbell-shaped concrete-filled steel tube arch bridge arch rib, concrete does not need to be poured into a cavity of the corrugated steel web, and the dead weight of the whole structure can be reduced; the corrugated steel webs are adopted between the upper circular steel pipes and the lower circular steel pipes of the main arch for shear resistance, stress of arch ribs can be optimized, and bin explosion of the webs is avoided.
本发明公开了一种应用波形钢腹板的哑铃型钢管混凝土拱肋结构，包括拱肋，拱肋包括上圆钢管和下圆钢管，上圆钢管与下圆钢管之间通过波形钢腹板焊接连接，拱肋上缘顶部或下缘底部设置吊杆锚固点，吊杆与拱肋上缘吊杆锚固点为承压板，吊杆与拱肋下缘吊杆锚固点为锚拉板，上圆钢管与下圆钢管内设有混凝土。施工方法包括：1)预制拱肋；2)吊装拱肋；3)灌注混凝土。本发明与现有技术相比的优点在于：结构明确，施工方便，利用波形钢腹板连接哑铃型钢管混凝土拱桥拱肋的上圆钢管和下圆钢管，波形钢腹板腔内无需灌注混凝土，能够减轻整体结构的自重；主拱上圆钢管和下圆钢管之间采用波形钢腹板抗剪，能够优化拱肋的受力，避免腹板“爆仓”。
