Prefabricated bridge deck slab structure of steel-concrete composite beam and construction method of prefabricated bridge deck slab structure
The invention discloses a prefabricated bridge deck structure of a steel-concrete composite beam and a construction method thereof.The bridge deck structure comprises a plurality of bridge deck units, the width of the bridge deck units is matched with the width of a bridge, an upper steel plate and a lower steel plate which correspond to each other are arranged in each bridge deck unit, and the lower steel plates are arranged along the full length of the bridge deck units; a plurality of shear nails are arranged on the top face of the lower steel plate, the upper steel plate and the lower steel plate are connected in a welded mode through a plurality of connecting studs, the connecting studs are higher than the shear nails, and the lower steel plate is located on the bottom face of the bridge deck unit and used for being connected with a steel main beam in a welded mode. According to the structure, the arrangement of conventional shear nails can be reduced by about 30%, the overall structural rigidity of the connecting nail group can be improved, the connecting performance of the bridge deck and the steel main beam can be effectively enhanced, and the connecting reliability between the bridge deck and the steel main beam is improved.
本发明公开了一种钢混组合梁的预制桥面板结构及其施工方法，桥面板结构包含若干桥面板单元，所述桥面板单元的宽度适配桥梁的宽度，所述桥面板单元内设有对应的上钢板和下钢板，所述下钢板沿所述桥面板单元通长设置，所述下钢板顶面设有若干剪力钉，所述上钢板和下钢板之间通过若干连接栓钉焊接连接，所述连接栓钉的高度高于所述剪力钉的高度，所述下钢板位于所述桥面板单元底面，所述下钢板用于焊接连接钢主梁。本结构可减少约30%的常规剪力钉的布置，还能提高连接钉群的整体结构刚度，还能有效加强桥面板与钢主梁的连接性能，提高桥面板与钢梁之间的连接可靠性。
