A Beam-to-Column Connecting Device of an Assembled Ribbed T-shaped Part

technical field

The invention belongs to the technical field of construction engineering equipment, and relates to a splicing node structure connected by high-strength bolts of steel frame nodes, in particular to a beam-to-column connection device of an assembled ribbed T-shaped piece.

Background technique:

At present, the connection joints between steel frame H-shaped steel columns and H-shaped steel beams generally adopt the form of bolted and welded hybrid connection structure. The two horizontal sectional welds between the upper and lower flanges of the beam and the column are transmitted to the column. These two horizontal sectional welds need to be welded on site, and the quality of the welds is very high; the labor intensity of on-site welding The quality of the weld is not easy to be guaranteed. Under strong earthquakes, due to potential weld defects, it is very easy to cause brittle failure at the connection joints, and may lead to the overall collapse of the structure.

Invention content:

The purpose of the present invention is to overcome the shortcomings of the prior art, and seek to design and provide a beam-to-column connection device for an assembled ribbed T-shaped piece. Avoid weld defects caused by welding on site, reduce labor intensity, and improve construction quality, and one side of the T-shaped piece is made with a reinforced rib plate, which can effectively improve the mechanical properties of the joints. This connection structure is suitable for H-shaped steel columns and H-shaped steel beam section.

In order to achieve the above object, the main structure of the present invention includes H-shaped steel columns, steel beam upper flange, steel beam lower flange, first high-strength bolts, second high-strength bolts, rib plates of ribbed T-shaped pieces, ribbed plate T-shaped The flange of the ribbed T-shaped piece and the web of the ribbed T-shaped piece; the left and right sides of the upper and lower ends of the H-shaped steel column are vertically installed with the flange of the ribbed T-shaped piece, and the middle of the flange of the ribbed T-shaped piece is horizontal The web of the ribbed T-piece is connected to the right-angled corner formed by the flange of the ribbed T-piece and the web of the ribbed T-piece is connected to the ribbed plate of the ribbed T-piece, ribbed The rib plate of the plate T-shaped piece, the flange of the ribbed T-shaped piece and the web of the ribbed T-shaped piece are combined to form a ribbed T-shaped piece; the H-shaped steel column and the flange of the ribbed T-shaped piece Bolt holes for the second high-strength bolts are reserved, and the flange of the T-shaped piece with ribs is vertically fixed and installed on the H-shaped steel column through the second high-strength bolts; the lower flange of the steel beam, the upper flange of the steel beam and the ribbed plate Bolt holes for the first high-strength bolts are reserved on the web of the T-shaped piece, and the web of the T-shaped piece with ribs is fixed and installed on the lower flange of the steel beam and the upper wing of the steel beam in the horizontal direction through the first high-strength bolts. edge.

Compared with the prior art, the present invention uses high-strength bolts to connect the H-shaped steel beam and the H-shaped steel column to realize on-site assembly, avoid on-site welding, avoid welding stress and welding deformation from adversely affecting the mechanical properties of the joint, and the joint form is suitable for Due to the splicing of H-shaped steel columns and H-shaped steel beams, the installation is simple, the construction speed is fast, and the construction cost is low, and one side of the T-shaped piece is made with a reinforced rib plate, which can effectively improve the mechanical properties of the joints and increase the joint stiffness.
