Triangular area corner structure of open-web prestressed concrete continuous rigid frame bridge
The invention discloses a triangular area corner structure of an open-web prestressed concrete continuous rigid frame bridge. The proper triangular area corner structure enables construction of the open-web type continuous rigid frame bridge to be convenient, safe and comfortable. The open web section comprises an open web section upper chord top plate, an open web section upper chord bottom plate, an open web section lower chord top plate, an open web section lower chord bottom plate, an open web section upper chord web, an open web section lower chord web and a web arc chamfer. The intersection section comprises an intersection section top plate, a fusion plate, a partition plate, an intersection section bottom plate and an intersection section web plate; the solid web section comprises a solid web section top plate, a solid web section bottom plate and a solid web section web plate; the prestressed steel beams comprise top plate prestressed steel beams, web long steel beams, web short steel beams and bottom plate prestressed steel beams. The internal force of the hollow section web can be transmitted to the fusion plate, the force is dispersed to the intersection section web, the intersection section top plate, the intersection section bottom plate and the fusion plate of the intersection section through the fusion plate, and sudden change of the internal force between the hollow section and the intersection section is reduced.
本发明公开了一种空腹式预应力混凝土连续刚构桥三角区角隅结构。合适的三角区角隅结构可使空腹式连续刚构桥施工便利、安全和舒适。本发明空腹段包括空腹段上弦顶板、空腹段上弦底板、空腹段下弦顶板、空腹段下弦底板、空腹段上弦腹板、空腹段下弦腹板和腹板圆弧倒角；交汇段包括交汇段顶板、融合板、隔板、交汇段底板和交汇段腹板；实腹段包括实腹段顶板、实腹段底板和实腹段腹板；预应力钢束包括顶板预应力钢束、腹板长钢束、腹板短钢束和底板预应力钢束。本发明可将空腹段腹板的内力传到融合板，通过融合板将力分散给交汇段的交汇段腹板、交汇段顶板、交汇段底板和融合板，减小空腹段到交汇段之间内力突变。
