Structure for hogging moment area of steel-concrete composite continuous beam bridge
The invention belongs to the technical field of bridges. The invention discloses a structure for a hogging moment area of a steel-concrete composite continuous beam bridge. The structure comprises a first prefabricated main beam and a second prefabricated main beam, notches are formed in opposite end parts of the first prefabricated body main beam and the second prefabricated body main beam, so that the notches of the first prefabricated body main beam and the second prefabricated body main beam are spliced to form a T-shaped joint of a vertical groove body of which the upper part is a zigzagedge and the middle lower part is a zigzag edge; the first prefabricated main beam and the second prefabricated main beam are each composed of a beam body formed by welding steel plates, the beam plates comprise I-shaped steel, bridge decks and end partition plates, the tops of the I-shaped steel are connected with the bridge decks, the bridge decks are in a step shape, and the end partition plates are welded to the junctions of the I-shaped steel and cast-in-place wet joints. The hogging moment area structure is novel in structure, convenient to construct and high in applicability, so that the cracking of concrete joints of the bridge decks in the hogging moment area is prevented, and the structural durability is improved.
本发明属于桥梁技术领域。一种用于钢‑混组合连续梁桥负弯矩区的构造，包括第一预制体主梁和第二预制体主梁；所述第一预制体主梁和第二预制体主梁的相对端部形成槽口，从而所述第一预制体主梁和第二预制体主梁的槽口拼接形成上部为锯齿状边缘的矩形条带、中下部为锯齿状边缘的竖直槽体的T型接缝；所述第一预制体主梁和第二预制体主梁均由钢板焊接而成的梁体组成，所述梁板包括工字钢、桥面板和端隔板，所述工字钢的顶部连接所述桥面板，所述桥面板呈阶梯形，所述工字钢与现浇湿接缝交界处焊有所述端隔板，本发明构造新颖、施工方便、适用性强的钢‑混组合连续梁桥负弯矩区构造，从而防止负弯矩区桥面板混凝土接缝处开裂，提高结构耐久性。
