Shear-tensile resistant connecting structure and application thereof in steel-UHPC bridge engineering
The invention discloses a shear-tensile resistant connecting structure and application thereof in steel-UHPC bridge engineering. The problem that the mechanical property of a hogging moment area is poor is solved. The shear-tensile connecting structure comprises a shear nail, a connecting sleeve and a tensile rib, the connecting sleeve is quickly and mechanically connected with the shear nail and fixed at the tail end of the shear nail, the connecting sleeve has a larger section than the shear nail, and the tensile rib is perpendicular to the shear nail and mechanically fixed on the connecting sleeve. And tensile strength along the bridge direction is provided. In the hogging moment area, the upper surface of the bridge is a bridge deck anti-crack structure, the lower side of the bridge is a steel-concrete base, shear nails, connecting sleeves and tensile ribs are arranged in the bridge deck anti-crack structure and the steel-concrete base, and the tensile ribs are arranged in the bridge direction. According to the technology, the occurrence condition of cracking of the hogging moment area of the bridge floor is restrained, and the anti-cracking capacity of the bridge floor is enhanced through the elastic concrete or the elastic asphalt.
本发明公开了一种抗剪‑拉连接构造及在钢‑UHPC桥梁工程中的应用，解决负弯矩区的力学性能不佳问题。该抗剪‑拉连接构造包括剪力钉、连接套筒和抗拉筋，所述连接套筒与剪力钉进行快速机械连接，并固定在剪力钉的末端，该连接套筒具有比剪力钉更大的断面，所述抗拉筋垂直于剪力钉并机械固定在所述连接套筒上，提供沿着顺桥向方向的抗拉。在负弯矩区，该桥梁的上表面为桥面抗裂构造，下侧为钢混底座，以及在所述桥面抗裂构造和钢混底座中设置剪力钉、连接套筒和抗拉筋，其中抗拉筋沿顺桥向设置。本技术抑制了桥面负弯矩区开裂的发生条件，并通过弹性混凝土或者弹性沥青，增强桥面抗裂能力。
