Chord member structure and system for steel truss-concrete composite structure
The invention discloses a chord member structure and system for a steel truss-concrete composite structure, and belongs to the technical field of bridge engineering, the chord member structure comprises a lower flange plate, a plurality of upper flange plates, webs and a plurality of PBL shear key parts, the number of the webs is the same as that of the upper flange plates, and a plurality of first shear nails are fixed on the lower flange plate; a plurality of second shear nails are fixed on the upper flange plate; each web comprises a lower end, a middle section and an upper end, each web is fixedly connected with the lower flange plate through the corresponding lower end, each web is fixedly connected with the corresponding upper flange plate through the corresponding upper end, the lower ends are perpendicular to the lower flange plates, the upper ends are perpendicular to the upper flange plates, and the middle sections are perpendicular to the upper ends. The multiple PBL shear key components penetrate through the middle sections correspondingly, so that the middle sections are connected through the PBL shear key components. The technical effects that the combining capacity between the steel and the concrete can be improved, construction is convenient and fast, and the quality is easy to guarantee are achieved.
本发明公开了一种用于钢桁架‑混凝土组合结构的弦杆构造及系统，属于桥梁工程技术领域，包括下翼缘板、多个上翼缘板、与多个所述上翼缘板数量相同的腹板、多个PBL剪力键部件，于所述下翼缘板上固定有多个第一剪力钉；于所述上翼缘板上固定有多个第二剪力钉；所述腹板包括下端、中间段和上端，每一个所述腹板通过所述下端和所述下翼缘板固定连接，所述腹板通过所述上端和对应的一个所述上翼缘板固定连接，所述下端和所述下翼缘板相垂直，所述上端和所述上翼缘板相垂直，多个所述PBL剪力键部件分别贯穿每一个所述中间段，以使每一个所述中间段通过PBL剪力键部件连接。本发明达到能够提升钢与混凝土之间的结合能力，施工便捷，质量易保证的技术效果。
