Steel-concrete combined bent cap
The invention discloses a steel-concrete combined bent cap. The steel-concrete combined bent cap comprises a steel-concrete combined bent cap shell installed on a reinforced concrete pier stud. The lower end face of the steel-concrete composite bent cap shell is provided with an open hole and a round hole, the upper end face of the reinforced concrete pier column is provided with a reserved groove, the steel-concrete composite bent cap shell is installed at the upper end of the reinforced concrete pier column, and the open hole is aligned with the reserved groove. The upper ends of a pluralityof longitudinal stress main ribs of the reinforced concrete pier column penetrate through the round holes and the open holes and extend into the steel-concrete combined bent cap shell, and the reserved grooves and the steel-concrete combined bent cap shell are filled with concrete. The advantages that steel is high in tensile strength, concrete is good in compression resistance and low in manufacturing cost are fully utilized, light construction and rapid construction of the bent cap are achieved, and the stress performance of the bent cap in the operation period is improved.
本发明公开了一种钢‑混凝土组合盖梁，包括安装在钢筋混凝土墩柱上的钢‑混凝土组合盖梁外壳。钢‑混凝土组合盖梁外壳的下端面设置开孔和圆孔，钢筋混凝土墩柱的上端面设置有预留槽，钢‑混凝土组合盖梁外壳安装到钢筋混凝土墩柱的上端，开孔与预留槽对齐，钢筋混凝土墩柱的若干纵向受力主筋的上端穿过圆孔和开孔并伸入钢‑混凝土组合盖梁外壳内，预留槽和钢‑混凝土组合盖梁外壳内填充混凝土。本发明充分利用钢材抗拉强度高、混凝土的抗压性能好与造价低的优点，实现了盖梁轻型化施工、快速施工，提高了盖梁运营期间的受力性能。
