Prestressed concrete cast-in-place box girder structure and construction method thereof
The invention relates to the technical field of bridge box girder construction, and especially relates to a prestressed concrete cast-in-place box girder structure and a construction method thereof. The prestressed concrete cast-in-place box girder structure comprises a bottom plate, webs arranged on the two sides of the upper surface of the bottom plate, a top plate arranged on the webs and flange plates arranged on the two sides of the top plate; a box-shaped cavity is defined by the bottom plate, the web plates and the top plate; a plurality of external prestressing tendons are obliquely arranged on the upper surface of the bottom plate, and a plurality of partition plates allowing the external prestressing tendons to penetrate through and be anchored are arranged on the bottom plate at intervals; and transverse prestressed reinforcements and longitudinal prestressed reinforcements are arranged on the bottom plate, the web plates and the top plate. The overall quality of the box girder structure is improved.
本申请涉及桥梁箱梁施工的技术领域，尤其是涉及一种预应力混凝土现浇箱梁结构及其施工方法，其中，一种预应力混凝土现浇箱梁结构包括底板、设在底板上表面两侧的腹板、设在腹板上的顶板和设在顶板两侧的翼缘板；所述底板、腹板和顶板围成一个箱型空腔；所述底板的上表面上倾斜设有多根体外预应力束，所述底板上间隔设有多个供体外预应力束穿设锚固的隔板；所述底板、腹板和顶板上均设有横向预应力钢筋和纵向预应力钢筋。本申请具有提高箱梁结构的整体质量的优点。
