Semi-open shear connector used in corrugated steel composite bridge deck slab
The invention relates to a semi-open shear connector used in a corrugated steel composite bridge deck slab, and belongs to the field of steel-concrete composite structures. The bridge deck slab comprises a corrugated steel plate, shear connectors and penetrating steel bars, the shear connectors are fixed on the center line of the trough of the corrugated steel plate, and arc half openings are uniformly formed in the upper parts of the shear connectors. Each arc-shaped opening is correspondingly provided with two penetrating steel bars, the bending shapes of the penetrating steel bars are consistent with the shape of the corrugated steel plate, the downward-concave parts in the middles of the penetrating steel bars are located in the troughs of the corrugated steel plate and penetrate through the arc-shaped half openings, and the two ends of each penetrating steel bar abut against the crests of the corrugated steel plate. The welding workload is small, the shearing force connecting piece is of a semi-open structure, only the penetrating reinforcing steel bar needs to be placed into a designated position during construction, and the problem that a traditional perforated plate shearing force connecting piece penetrates through the reinforcing steel bar difficultly is solved; an elliptical hole is formed in the bottom, so the anti-shearing bearing capacity is further improved. Dueto the characteristics of the structure, certain deformation can be generated when the structure is loaded, and therefore the structure has good ductility.
本发明涉及一种用于波形钢组合桥面板中的半开口剪力连接件，属于钢‑混组合结构领域，包括波形钢板、剪力连接件、贯穿钢筋，所述剪力连接件固定在波形钢板波谷的中线上，剪力连接件的上部均匀地开设有弧形半开口，每个弧形开口对应安装两根贯穿钢筋，贯穿钢筋的弯折形状与波形钢板形状一致，贯穿钢筋中部的下凹部分位于波形钢板的波谷中且从弧形半开口中穿过，贯穿钢筋的两端搭靠在波形钢板波峰上。本发明的焊接工作量较小，剪力连接件为半开口结构，施工时只需要将贯穿钢筋放入指定位置即可，克服了传统的开孔板剪力连接件贯穿钢筋困难的问题；在底部开椭圆孔又进一步提高了抗剪承载能力。由于构造的特点，受荷载时会有一定的变形量，所以具有较好的延性。
