[0001] The utility model relates to the technical field of high steel beams, in particular to a connection structure of steel beams of unequal heights. Background Art

[0002] Various steel frame structures are often used in the process of construction. Hot-rolled H-shaped steel is increasingly used in various building steel structures because of its better performance advantages, especially some box column structures and some unequal height steel beam connection structures.

[0003] In the authorized patent document with the announcement number CN211621958U, a connection structure of steel beams of unequal height is disclosed, which belongs to the field of building construction engineering technology. It includes a box column, a first steel beam and a second steel beam. The first steel beam and the second steel beam are respectively located on both sides of the box column and welded to the box column. The bottom surface of the first steel beam is lower than the bottom surface of the second steel beam. A first cross diaphragm is provided inside the box column. The first cross diaphragm includes a first connecting plate and a first fixed plate. The two ends of the first connecting plate are fixedly connected to the first fixed plate. The first fixed plate is connected to the first fixed plate. An upper angle steel is connected between the first steel beam and the box column. A first connecting bolt is connected between the upper angle steel and the first steel beam. The first fixing bolt is fixedly connected to the first fixed plate, the box column and the upper angle steel at the same time. The second steel beam is connected to the box column with the same upper angle steel, which has the effect of high connection strength.

[0004] The above device uses L-shaped angle steel to fix the first steel beam, the second steel beam and the box column. When the first steel beam, the second steel beam and the box column are offset, the stress response of the L-shaped angle steel is poor and the connection effect will be worse. Utility Model Content

[0006] An embodiment of the present application provides a connection structure of steel beams of unequal heights, including a box-type column, wherein a first steel beam and a second steel beam are preliminarily welded to both sides of the box-type column, respectively. The first steel beam and the second steel beam have different heights, and triangular blocks are preliminarily welded to the right-angle ends of the first steel beam, the second steel beam and the box-type column, respectively. The triangular blocks are made of alloy steel, and an internal support mechanism is provided inside the box-type column. The internal support mechanism includes an X-plate, and the X-plate abuts against the inner wall of the box-type column.

[0007] By adopting the above technical solution, the X-plate of the internal support mechanism can support the inside of the box column, and the right-angle position of the connection between the first steel beam, the second steel beam and the box column adopts a triangular block connection method. The triangular block is alloy steel and has good oxidation resistance, corrosion resistance and strength. Therefore, when the box column, the first steel beam and the second steel beam are offset, the box column, the first steel beam and the second steel beam are well supported. This connection method can better prevent the box column, the first steel beam and the second steel beam from being completely deformed.

[0008] Optionally, the upper end and the lower end of the X-plate are respectively fixedly connected with a transverse plate, and the transverse plate is slidably connected to the box-type column.

[0009] By adopting the above technical solution, the X-plate can fix the transverse plate, and the X-plate can support the box-type column.

[0010] Optionally, the four corners of the X-plate are arranged in a 90-degree triangle shape.

[0011] By adopting the above technical solution, the four corners of the X-plate are arranged in a 90-degree triangle shape, which can simultaneously abut the inner wall of the box column and the cross plate, thereby providing better support for the box column.

[0012] Optionally, two fixing plates are fixedly connected to one side of the two transverse plates away from the X plate.

[0013] By adopting the above technical solution, the fixed plate can be fixed by the transverse plate.

[0014] Optionally, the first steel beam and the second steel beam are arranged in an I-shape, and five-sided blocks are preliminarily welded at the grooves of the first steel beam and the second steel beam respectively.

[0015] By adopting the above technical solution, the setting of the five-sided block can further support the empty grooves of the first steel beam and the second steel beam, preventing the first steel beam and the second steel beam from bending at the thin edges.

[0016] Optionally, the outer walls of the pentagonal block and the triangular block are respectively provided with a plurality of bolt holes, and the pentagonal block, the triangular block, the fixed plate, the first steel beam, the second steel beam and the box column are further fixed and installed by bolts and nuts respectively.

[0017] By adopting the above technical solution, the cooperation of bolts and nuts can further fix the pentagonal blocks, triangular blocks, fixed plates, first steel beams, second steel beams and box columns, thereby strengthening the fixation of the pentagonal blocks, triangular blocks, fixed plates, first steel beams, second steel beams and box columns.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0019] The technical solution of the present application can support the interior of the box column through the X-plate of the internal support mechanism, and the right-angle position of the connection between the first steel beam, the second steel beam and the box column adopts a triangular block connection method. The triangular block is alloy steel and has good oxidation resistance, corrosion resistance and strength. Therefore, when the box column, the first steel beam and the second steel beam are offset, it can provide good support for the box column, the first steel beam and the second steel beam. This connection method can better prevent the box column, the first steel beam and the second steel beam from being completely deformed. BRIEF DESCRIPTION OF THE DRAWINGS
