Cover beam structure and construction method thereof
The invention discloses a bent cap structure and a construction method thereof. The bent cap structure comprises a pier, a prefabricated groove body, a second reinforced concrete combination block, a first reinforced concrete combination block and a prestress assembly. The prefabricated groove body is used for being installed on a pier and comprises a pier top groove section and two cantilever groove sections which are separated from each other through a partition plate. The two second reinforced concrete combination blocks are fixed into the two cantilever groove sections correspondingly, and the first reinforced concrete combination block is fixed into the pier top groove section. The prestress assembly comprises a first prestress rib and a second prestress rib. The first prestressed tendons are installed on the first reinforced concrete combination blocks so as to balance the bending moment of the first reinforced concrete combination blocks. The two ends of the second prestressed tendon are fixed to the two second reinforced concrete combination blocks correspondingly so as to balance the bending moment of the two second reinforced concrete combination blocks. The mode of combining the prefabricated groove body and cast-in-place is adopted, the transportation and hoisting difficulty is lowered, and the strength, durability and construction efficiency of the cover beam are improved.
本发明公开了一种盖梁结构及其施工方法，其中盖梁结构包括桥墩、预制槽体、第二钢筋混凝土组合块、第一钢筋混凝土组合块和预应力组件。预制槽体用于安装在桥墩上，包括通过分隔板相互间隔墩顶槽段和两个悬臂槽段。两个第二钢筋混凝土组合块分别固定于两个悬臂槽段内，第一钢筋混凝土组合块固定于墩顶槽段内。预应力组件包括第一预应力筋和第二预应力筋。第一预应力筋安装于第一钢筋混凝土组合块上，以平衡第一钢筋混凝土组合块的弯矩。第二预应力筋的两端分别固定于两个第二钢筋混凝土组合块上，以平衡两个第二钢筋混凝土组合块的弯矩。本发明采用预制槽体与现场浇筑相结合的方式，降低了运输和吊装难度，提高了盖梁的强度、耐久性及施工效率。
