Simplified structure of hogging moment area of concrete continuous beam
The invention discloses a simplified structure of a hogging moment area of a concrete continuous beam. The simplified structure comprises a steel bar structure and a concrete pouring structure. The steel bar structure comprises constructional steel bars arranged on a hogging moment area cast-in-place section and anti-bending steel bars arranged on a hogging moment area bridge deck slab section. The constructional steel bars are fixedly connected with beam end steel bars; the constructional steel bars are fixedly connected with the anti-bending steel bars; wherein the hogging moment area cast-in-place section is located between two adjacent beam ends, the hogging moment area bridge deck slab section is located above the two adjacent beam ends and above the hogging moment area cast-in-placesection, and an integral T-shaped structure formed by simultaneously pouring concrete on the hogging moment area bridge deck slab section and the hogging moment area cast-in-place section is a concrete pouring structure. Compared with the prior art, the simplified structure has advantages that hogging moment is resisted by arranging common steel bars and pouring high-performance concrete, the construction process is simple, and the cost is low.
本发明公开了一种混凝土连续梁负弯矩区简化结构，包括钢筋结构和混凝土浇筑结构。钢筋结构包括布设于负弯矩区现浇段的构造钢筋和布设于负弯矩区桥面板段的抗弯钢筋，构造钢筋与梁端钢筋固定相连，构造钢筋与抗弯钢筋固定相连，负弯矩区现浇段位于相邻的两个梁端之间，负弯矩区桥面板段位于相邻的两个梁端的上方以及负弯矩区现浇段的上方，在负弯矩区桥面板段和负弯矩区现浇段同时浇筑混凝土形成的整体T形结构为混凝土浇筑结构。与现有技术相比，本发明通过布设普通钢筋并且浇筑高性能混凝土来抵抗负弯矩，施工过程简单，成本较低。
