Description

Technical Field

[0001] This utility model relates to the field of steel structure connection technology, specifically a connection node between a steel structure box column and a box beam. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel profiles and steel plates, and uses rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing.

[0003] The existing method of connecting box columns and box beams directly with bolts or bolt-fitted joints has a small stress-bearing area at the connection point. When the load-bearing capacity is too large, the connection will become unstable, affecting the overall stability.

[0004] Therefore, it is necessary to propose a connection node between a steel structure box column and a box beam. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a connection node between a steel structure box column and a box beam, which has the advantage of effectively improving the stress on the connection node to ensure overall stability, thus solving the problems mentioned in the background technology.

[0006] This utility model provides the following technical solution: a connection node between a steel structure box column and a box beam, comprising a box column and a box beam:

[0007] The box girder is connected to the side of the box column;

[0008] The box column has four sets of mounting holes on its side. Angle steel is attached to the upper and lower parts of the side of the box column. The angle steel is threaded to the box column with a single-sided high-strength bolt. The ends of two sets of single-sided high-strength bolts are threaded to the inside of the mounting holes. A channel steel is attached to the other side of the angle steel, and a channel steel is attached to the other side of the angle steel. The channel steel is provided with mounting holes. The two sets of single-sided high-strength bolts are threaded to the inside of the mounting holes. A box beam is attached to the inside of the opposite sides of the channel steel.

[0009] Preferably, one side of the angle steel is welded to the side of the box column, and the other side of the angle steel is welded to the surfaces of channel steel one and channel steel two.

[0010] Preferably, the single-sided high-strength bolts connecting the channel steel one and the channel steel two to the angle steel are simultaneously connected to the internal threads of the box beam.

[0011] Preferably, the inner width values ​​of the first channel steel and the second channel steel are slightly larger than the width value of the box girder.

[0012] Preferably, the specifications of each group of angle steel are the same, and the diameters of the first mounting hole and the second mounting hole are the same.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this type of steel structure box column and box beam connection node, four sets of angle steel are installed on the side of the box column using single-sided high-strength bolts and mounting holes. The four sets of angle steel are then welded to the box column. At this time, channel steel one and channel steel two are placed on the sides of the adjacent two sets of angle steel and installed on the angle steel by welding. The box beam to be connected is inserted into the square formed by the combination of channel steel one and channel steel two. The box beam is then limited and installed using single-sided high-strength bolts and mounting holes, thus completing the installation of one set of box beams and box columns. One or more sets of box beams can be installed in the same way. This structure can effectively connect the box beams to the box columns. The double reinforcement of bolts and welding strengthens the connection stability between the box columns and box beams. The angle steel enhances the load-bearing capacity of the box columns on the box beams and improves the stress of the connection node. Attached Figure Description

[0023] Steel structures are structures made of steel materials and are one of the main types of building structures. They are primarily composed of steel beams, columns, trusses, and other components made of shaped steel and steel plates, and undergo rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, steel structures are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields. Steel structures are prone to corrosion and generally require rust removal, galvanizing, or painting, as well as regular maintenance.

[0024] In the main structure of the steel structure, box columns and box beams are used to form the overall frame, and most of the force of the overall frame is borne by the box columns and box beams.
