Concrete-filled steel pipe column-beam joint structure and construction method thereof
The invention discloses a concrete-filled steel pipe column-beam joint structure, and belongs to the technical field of constructional engineering. The concrete-filled steel pipe column-beam joint structure comprises a steel pipe column, a steel pipe beam, an installing and connecting base and a double-bolt fastening assembly, wherein the steel pipe column and the steel pipe beam are composed of inner-layer steel pipes, outer-layer steel pipes, fin strips and concrete mortar poured between the inner-layer steel pipes and the outer-layer steel pipes, the installing and connecting base is composed of a base plate and a sleeve, the double-bolt fastening assembly comprises two bolts, six nuts and two pressing pieces, the turning directions of external threads at the bottom ends and the top ends of screw rods on the bolts are opposite, two through holes are formed in the pressing pieces, the inner diameter of the through holes is slightly larger than the outer diameter of the screw rods, and the double-bolt fastening assembly is fastened by adopting a reverse fastening method. The concrete-filled steel pipe column-beam joint structure and the construction method thereof have the beneficial effects that the strength of the steel pipe column and the strength of the steel pipe beam are improved through the fin strips, and a joint structure of the steel pipe beam and the steel pipe column can be installed more firmly and cannot be loosened on the whole by adopting the double-bolt fastening assembly and the reverse fastening method.
一种钢管混凝土柱梁节点结构，建筑工程技术领域，其包括钢管柱、钢管梁、装接座和双螺栓紧固组件；所述钢管柱和钢管梁由内外层钢管、翼片条和灌注在内外层钢管之间的混凝土砂浆构成，所述装接座由座板和套筒构成，所述双螺栓紧固组件包括两只螺栓、六只螺母和两只压片，其中螺栓上螺杆的底端和顶端上的外螺纹旋向相反，所述压片上有两个通孔，所述通孔的内径略大于螺杆的外径；所述双螺栓紧固组件采用反向紧固法进行紧固；其有益效果是采用翼片条提高了钢管柱和钢管梁的强度，采用双螺栓紧固组件和反向紧固法可以在整体上钢管梁和钢管柱的节点结构安装更加牢固且不会松脱。
