Shearing force connecting piece, steel-concrete composite beam comprising shearing force connecting piece and construction method of steel-concrete composite beam
The invention discloses a shearing force connecting piece, a steel-concrete composite beam comprising the shearing force connecting piece and a construction method of the steel-concrete composite beam. The shearing force connecting piece comprises an inverted-pyramid-frustum-shaped barrel (7), stiffening pieces, a cover plate, penetrating steel bars (8) and high-strength bolts (21). The stiffener comprises a stiffener bottom plate (13) and a stiffener side plate (14) which are integrally formed, the stiffener bottom plate is consistent with the lower opening of the cylinder in size and is attached to the lower opening of the cylinder, a second connecting hole for connecting the high-strength bolt is formed in the stiffener bottom plate, and the stiffener side plate is arranged around the stiffener bottom plate and is attached to the inner wall of the cylinder; the stiffening side plates are lower than the first connecting holes; the cover plate covers the upper opening of the cylinder body; the penetrating reinforcing steel bar transversely penetrates through the cylinder body through the first connecting hole, and connecting sections are reserved on the two sides of the cylinder body respectively; the high-strength bolts are connected with the stiffening bottom plate through the second connecting holes. According to the invention, disassembly and replacement of all parts of the shear connector and the prefabricated bridge deck are realized; and the structural form and the stress performance of the shearing force connecting piece are optimized.
本发明公开了一种剪力连接件、含该剪力连接件的钢混组合梁及其施工方法。所述剪力连接件包括倒棱台型的筒体(7)、加劲件、盖板、贯穿钢筋(8)及高强螺栓(21)；加劲件包括一体成型的加劲底板(13)和加劲侧板(14)，加劲底板的大小与筒体的下开口大小一致，并贴合筒体的下开口，加劲底板上设置有供高强螺栓连接的第二连接孔，加劲侧板围绕加劲底板设置，并贴合筒体的内壁，加劲侧板的高度低于第一连接孔；盖板盖在筒体的上开口处；贯穿钢筋经第一连接孔横向穿过筒体，并在筒体的两侧分别留有连接段；高强螺栓经第二连接孔连接加劲底板。本发明实现了剪力连接件各部件及预制桥面板的拆卸更换；剪力连接件构造形式和受力性能的优化。
