Connecting piece of anti-pulling and non-anti-shearing open type steel-concrete composite beam
The invention discloses a connecting piece of an anti-pulling and non-anti-shearing open type steel-concrete composite beam. The connecting piece is used for solving the technical problem that an existing connecting piece such as a shear nail or a shear shear is unfavorable for the structure stress of a hogging moment area. The connecting piece is applied to a hogging moment area of a steel-concrete composite beam structure, the tensile stress of a concrete bridge deck in the hogging moment area can be reduced, the prestress applying effect can be improved through the longitudinal non-shear-resisting measure, and the vertical pulling resistance can resist the vertical separation and lifting effect of concrete and a steel beam. The connecting piece comprises an open steel plate used for being installed on a steel beam, and the open steel plate is provided with a bent installation hole; and the penetrating reinforcing steel bar is used for being embedded in the concrete structure of the concrete slab, the penetrating reinforcing steel bar penetrates through the mounting hole, and the penetrating arrangement is configured to allow the penetrating reinforcing steel bar to generate displacement of a specified degree relative to the mounting hole. The connecting piece is simple in structure and convenient to construct.
本申请公开了一种抗拔不抗剪开口型钢‑砼组合梁的连接件。该连接件，用来解决现有剪力钉或剪力剪等连接件对负弯矩区结构受力不利的技术问题。连接件应用于钢‑混凝土组合梁结构负弯矩区，能减小负弯矩区混凝土桥面板的拉应力，纵向不抗剪措施能提高预应力施加效果，而竖向抗拔能力能抵抗砼与钢梁的竖向分离和掀起作用。该连接件包括：一开口钢板，用以安装在钢梁上，开口钢板具有呈现弯折状的安装孔；和一贯穿钢筋，用以埋入混凝土板的混凝土结构内部，贯穿钢筋穿设安装孔内，该穿设被配置成允许贯穿钢筋相对于所述安装孔发生指定程度的位移。本申请的连接件构造简单，便于施工。
