Background technique:

At present, steel frame beam-column rigid connection joints generally adopt the bolt-welding hybrid connection form. When the beam and column are connected, the vertical shear force at the beam end is transmitted to the column through the high-strength bolts of the beam web, and the beam end bending moment is transmitted through the upper and lower beams. The two horizontal sectional welds between the flange and the column are passed to the column. These two horizontal sectional welds need to be welded on site, and the quality of the welds is very high; the upper column and the lower column are butt welded on site. Seam connection; these on-site welding are labor-intensive, and the quality of the weld is not easy to guarantee. Under the action of strong earthquakes, due to potential weld defects, brittle failures at the joints are likely to occur, which may lead to the overall collapse of the structure.

Type high-strength bolts and high-strength through-bolt connections, so that it can avoid weld defects caused by welding at the construction site, effectively improve the mechanical properties of joints, reduce labor intensity, and improve construction quality. The cast steel outer sleeve is suitable for rectangular steel pipe column sections , especially when the section of the rectangular steel pipe column is larger, the applicability is stronger, and the rigidity of the joint is effectively enhanced by using the cast steel outer sleeve, which meets the seismic design requirements of strong joints and weak members.

In order to achieve the above object, the main structure of the present invention includes an upper steel pipe column, a lower steel pipe column, a steel beam upper flange, a steel beam lower flange, a cast steel outer sleeve, high-strength piercing bolts, high-strength bolts, and a T-shaped piece flange and T-shaped web; the upper steel pipe column is embedded in the cuboid structure of the cast steel outer sleeve, and the upper steel pipe column and the lower steel pipe column are planed and tightly connected; the left and right sides of the upper and lower ends of the cast steel outer sleeve are symmetrical and vertical The T-shaped flange is installed in the direction, and the middle of the T-shaped flange is horizontally connected with the T-shaped web, and the T-shaped flange and the T-shaped web are combined to form a T-shaped piece; the lower steel pipe column, the cast steel jacket The lower end of the sleeve and the flange of the T-shaped piece at the lower end of the cast steel outer sleeve are respectively reserved with bolt holes for matching with high-strength bolts, and the flange of the T-shaped piece at the lower end of the cast steel outer sleeve is vertically fixed and installed by high-strength bolts On the lower steel pipe column; the upper steel pipe column, the upper end of the cast steel outer sleeve and the flange of the T-shaped piece at the upper end of the cast steel outer sleeve are reserved with bolt holes for matching with high-strength cross bolts, and the upper end of the cast steel outer sleeve The flange of the T-shaped piece is vertically fixed and installed on the upper steel pipe column through high-strength cross bolts; the lower flange of the steel beam and the web of the T-shaped piece connected to the lower end of the cast steel outer sleeve are reserved There are bolt holes for high-strength bolts, and the T-shaped web connected to the T-shaped flange at the lower end of the cast steel outer sleeve is horizontally fixed and installed on the lower flange of the steel beam through high-strength bolts; The web of the T-shaped piece connected to the flange of the T-shaped piece at the upper end of the steel outer sleeve is reserved with bolt holes for matching with high-strength bolts, and the web of the T-shaped piece connected with the flange of the T-shaped piece at the upper end of the cast steel outer sleeve It is fixed horizontally on the upper flange of the steel beam by high-strength bolts.

Compared with the prior art, the present invention uses high-strength bolts to connect the H-shaped steel beam and the rectangular steel pipe column, which avoids the adverse effects of welding stress and welding deformation on the mechanical properties of the joint. The splicing of such cross-section steel pipe columns has no welding on site, fast construction speed, convenient installation, low production cost, and few nodes protrude from the outer circumference of the column, which is simple and beautiful, and will not affect the design and installation of adjacent components.
