Prestressed fish belly sill based on hinge structure
The invention relates to a hinged structure-based prestressed fish-bellied sill, and relates to the technical field of fish-bellied sills, the hinged structure-based prestressed fish-bellied sill comprises triangular beams, a waist beam, a stay bar and a steel strand, the triangular beams are arranged at two ends of the waist beam, two ends of the steel strand are fixedly connected with the triangular beams, and the triangular beams are hinged to the waist beam through a hinged structure; the supporting rods are fixedly arranged on the waist beam, the multiple supporting rods are arranged in the length direction of the waist beam, and the ends, away from the waist beam, of the supporting rods are provided with bridge frames used for supporting steel strands. The triangular beam and the waist beam are hinged through the hinge structure, the zero bending moment point of soil body pressure is controlled at the hinge joint, the bending moment at the joint is zero, the joint is effectively prevented from being damaged, and safety is improved.
本申请涉及一种基于铰接结构的预应力鱼腹梁，涉及鱼腹梁技术领域，包括三角形梁、腰梁、撑杆和钢绞线，所述三角形梁设置于腰梁的两端，所述钢绞线的两端与三角形梁固定连接，所述三角形梁通过铰接结构与腰梁铰接，所述撑杆固定设置于腰梁上，且撑杆沿腰梁的长度方向设置多个，所述撑杆远离腰梁的一端设置有用于支撑钢绞线的桥架。本申请通过铰接结构将三角形梁与腰梁铰接，将土体压力的弯矩零点控制在铰接节点处，使得该连接处的弯矩为零，有效的防止该处发生破坏，提高安全性。
