Top structure of concrete-filled steel tube combined tower, concrete-filled steel tube combined tower and bridge
The invention relates to a top structure of a concrete-filled steel tube combined tower, the concrete-filled steel tube combined tower and a bridge, the top structure comprises a stiff skeleton column and a steel truss, the steel truss comprises a bottom steel plate and a top steel plate, a main steel tube of the stiff skeleton column is connected to the bottom of the bottom steel plate, and a longitudinal web and a transverse web are connected between the top steel plate and the bottom steel plate; first through holes are formed in the bottom steel plate, the top steel plate, the longitudinal webs and the transverse webs correspondingly, first steel bars penetrate through the first through holes to form PBL shear keys, and the top area of the stiff framework column and the steel truss girder are wrapped with concrete. The steel truss girder, the main steel pipe and the encased concrete are connected into a whole through the PBL shear keys, huge pressure at the cable saddle can be transmitted to the stiff framework column, fixed connection of the steel truss girder and the stiff framework column is achieved, the steel truss girder, the main steel pipe and the encased concrete work cooperatively, the structural integrity is good, joint force transmission is clear, and the structure is simple. The top structure is simple in structure, convenient to operate, short in construction period and good in effect.
本发明关于一种钢管混凝土组合塔的顶部构造、钢管混凝土组合塔及桥梁，该顶部构造包括劲性骨架柱和钢桁梁，钢桁梁包括底钢板和顶钢板，劲性骨架柱的主钢管连接于底钢板底部，顶钢板和底钢板之间连接有纵向腹板和横向腹板，底钢板、顶钢板、纵向腹板和横向腹板上分别设有第一通孔，第一通孔内穿设有第一钢筋形成PBL剪力键，劲性骨架柱顶部区域和钢桁梁外包混凝土。本发明通过PBL剪力键将钢桁梁、主钢管和外包混凝土连接形成一个整体，可将索鞍处的巨大压力传递给劲性骨架柱，实现了钢桁梁和劲性骨架柱固定连接，钢桁梁、主钢管和外包混凝土协同工作，结构整体性好，节点传力明确，该顶部构造结构简单、操作方便、施工周期短，效果良好。
