Novel composite beam with transverse steel plate high-strength bolt connecting pieces and tooth-shaped perforated steel plate connecting pieces
The invention discloses a novel composite beam with a transverse steel plate high-strength bolt connecting piece and a tooth-shaped perforated steel plate connecting piece. The novel composite beam comprises a steel beam, a bent tooth-shaped perforated steel plate, a concrete plate, a penetrating reinforcing steel bar, a distributing reinforcing steel bar, a high-strength bolt and a concrete tenon. The bent tooth-shaped perforated steel plates are cut on the T-shaped steel to penetrate through the steel bars, so that the perforated steel plate connecting pieces are formed to connect the concrete and the steel beams, meanwhile, the bent steel beams can resist pressure above, and vertical displacement can be limited more reasonably through the high-strength bolt connecting pieces. The structure is simple, a combined beam structure form of a novel connecting piece is provided, construction is convenient and fast, reliable and effective transmission of shearing force between steel and concrete is guaranteed while the mechanical advantages of the steel and the concrete are fully utilized, the perforated plate connecting piece has higher shear bearing capacity compared with a welding stud, and the connecting piece is suitable for being used for a large-scale production line. The high-strength bolt connecting piece has good mechanical performance to resist longitudinal shearing force and transverse lifting force, has good shearing resistance and can limit vertical displacement.
本发明公开了一种带横向钢板高强螺栓连接件与齿状开孔钢板连接件的新型组合梁，包括钢梁、弯折齿状开孔钢板、混凝土板、贯穿钢筋、分布钢筋、高强螺栓和混凝土榫。通过在T型钢上切割出弯折齿状开孔钢板来通过贯穿钢筋，从而形成开孔钢板连接件连接混凝土与钢梁，同时弯折的钢梁可以抵抗上方的压力并且通过高强螺栓连接件可以更合理的限制竖向位移。本发明结构简单，提出一种新型连接件的组合梁结构形式，施工方便快捷，且充分利用钢和混凝土各自的力学优势的同时，保证了钢与混凝土之间剪力的可靠有效传递，开孔板连接件具有相对焊钉更高的抗剪承载力，具有良好的力学性能抵抗纵向剪力和横向掀起力，高强螺栓连接件具有很好的抗剪性能，且能限制竖向位移。
