Concrete-filled steel tube beam column joint structure for building and manufacturing method thereof

The invention discloses a concrete-filled steel tube beam column joint structure for building and a manufacturing method thereof. The concrete-filled steel tube beam column joint structure comprises a concrete-filled steel tube column and externally-wrapped U-shaped steel, wherein the concrete-filled steel tube column comprises an upper-section steel tube column and a lower-section steel tube column, the concrete-filled steel tube beam column joint structure is characterized in that an anti-shearing mechanism is arranged between the upper-section steel tube column and the lower-section steel tube column, the anti-shearing mechanism comprises a connecting plate, the connecting plate is provided with an inner hole, four symmetrical air holes are formed in the connecting plate on the periphery of the inner hole, a shear steel cylinder which extends upwards and is located in an inner cavity of the upper-section steel tube column is welded to the edge of the inner hole, the shear steel cylinder is provided with a short-edge cylinder which is integrally formed, penetrates through the inner hole and extends downwards, and a connecting steel cylinder which extends downwards and is located in an inner cavity of the lower-section steel tube column is welded to an outer ring of the edge of the inner hole.

本发明公开了一种建筑用钢管混凝土梁柱节点结构及其制造方法，包括钢管混凝土柱和外包U形钢，所述钢管混凝土柱包括上段钢管柱和下段钢管柱，其特征在于：在所述上段钢管柱和下段钢管柱之间设置有抗剪机构，所述抗剪机构包括连接板，所述连接板具有内孔，所述内孔四周的连接板上设置有四个对称的透气孔；所述内孔边沿焊接有向上伸出位于所述上段钢管柱内腔之中的剪力钢筒，且所述剪力钢筒具有一体成型的穿过所述内孔向下延伸的短边筒，所述内孔边沿的外圈焊接有向下伸出且位于所述下段钢管柱内腔之中的连接钢筒。
