Composite concrete filled steel tubular column beam column joint and column-column inner steel pipe flange connecting system
The invention discloses a composite concrete filled steel tubular column beam column joint and column-column inner steel pipe flange connecting system. A composite concrete filled steel tubular columnis composed of an outer steel pipe and an inner steel pipe. An overhung steel beam comprises an inner steel beam and an outer steel beam of the outer steel pipe and an outer steel beam of the inner steel pipe. A stiffening component comprises longitudinal PBL stiffening ribs, cross separation plates and longitudinal stiffening ribs between the cross separation plates. The inner steel pipe and theouter steel pipe in the composite concrete filled steel tubular column are divided into two parts, and are not connected into a whole, and outer flanges are arranged at the upper end and the lower end of the inner steel pipe. In the construction process, the inner steel pipe is firstly mounted, the inner steel pipe is connected with an inner steel pipe of a lower column through the outer flanges,and then the outer steel pipe is mounted. The inner steel pipe and the outer steel pipe are both prefabricated in a factory, the steel pipes in the upper column and the lower column are connected through the flanges, and the inner steel pipe and the outer steel pipe are connected through a bolt; and the outer pipes of the upper column and the lower column are welded, the construction difficulty is greatly reduced, the industrial needs can be greatly met, the construction efficiency is improved, and the construction period is shortened.
本发明公开了一种复合钢管混凝土柱梁柱节点及柱‑柱内钢管法兰连接体系，复式钢管混凝土柱由外钢管和内钢管组成；外伸钢梁包括外钢管的内外钢梁和内钢管的外钢梁；加劲部件包括纵向的PBL加劲肋、横隔板及横隔板间的纵向加劲肋组成。复式钢管混凝土柱的的内、外钢管分成两部分，未连接成整体，内钢管的上下端有外法兰，在施工过程中，先进行内钢管的安装，其通过外法兰与下柱的内钢管连接，而后进行外钢管的安装；内外钢管均在工厂预制完成，且上下柱内钢管通过法兰连接，内外钢管也通过螺栓连接，上下柱的外管通过焊接连接，极大地降低了施工的难度，可极大地适应工业化的需求，提高了施工效率并缩短了施工工期。
