Description

Technical Field

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

[0002] The design of steel structure beams and columns follows the principles of mechanics. Through reasonable cross-sectional shape and size design, optimized load-bearing capacity and economic benefits are achieved. Steel structure beams and columns have excellent load-bearing capacity, which can effectively support the weight of the building and transfer it to the foundation. In the event of natural disasters such as earthquakes, the elastic-plastic deformation capacity of beams and columns helps to dissipate earthquake energy and protect the building from damage.

[0003] In existing technologies, beams are mostly connected and fixed to the side walls of steel structure columns. The strength of the connection nodes is low, which can easily lead to unreliable connections between beams and columns, thus affecting the stability of the overall structure. When subjected to loads, the nodes are prone to deformation or damage, resulting in a reduction in the safety of the overall structure. Utility Model Content

[0004] This utility model provides a steel structure beam-column connection node structure, which aims to solve the problem that most beams are connected and fixed to the side walls of steel structure columns, resulting in low connection node strength.

[0005] This utility model is implemented as follows: a steel structure beam-column connection node structure includes a column, a first connecting beam is provided through the inside of the column, and a second connecting beam is provided through the inside of the first connecting beam, with both ends extending to the outside of the column. The first connecting beam and the second connecting beam form a cross shape.

[0006] The four side walls of the column are each provided with a number of steel bars, and the steel bars surround the outside of the second connecting beam and the first connecting beam.

[0007] Both ends of the surfaces of the plurality of steel bars corresponding to the second connecting beam are fitted with second crossbeam connecting parts that cover the outer ends of the second connecting beam. Both ends of the surfaces of the plurality of steel bars corresponding to the first connecting beam are fitted with first crossbeam connecting parts that cover the outer ends of the first connecting beam. The outer surface width of the second crossbeam connecting parts and the first crossbeam connecting parts is smaller than the width of the corresponding side wall of the column, forming a crossbeam installation gap.

[0008] Preferably, the front and rear sides of the column are provided with a second opening that is adapted to the first connecting beam.

[0009] Preferably, one end face and the other end face of the column are provided with a first opening adapted to the second connecting beam, and the surface of the first connecting beam is provided with a through opening adapted to the second connecting beam.

[0010] Preferably, when the second connecting beam passes through the interior of the through opening, the top of the second connecting beam is flush with the top of the first connecting beam, and a connecting plate located inside the column is welded between the top of the second connecting beam and the top of the first connecting beam.

[0011] Preferably, the side walls of the second connecting beam, the first connecting beam, and the column are all provided with a plurality of insertion slots that are adapted to the steel reinforcement body.

[0012] Preferably, a plurality of second reinforcing plates are provided between the outer surface of the second connecting beam and the inner wall of the second crossbeam connection portion, and a plurality of first reinforcing plates are provided between the outer surface of the first connecting beam and the inner side of the first crossbeam connection portion.

[0013] Preferably, both the top of the second crossbeam connecting part and the top of the first crossbeam connecting part are provided with a plurality of mounting holes.

[0014] Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The steel structure beam-column connection node structure of this utility model has a first connecting beam penetrating the interior of the column, and a second connecting beam sequentially penetrating the interior of the column and the first connecting beam to form a connection support node. After multiple steel bars are inserted, they are combined with the outer casing of the second crossbeam connection part and the first crossbeam connection part. The steel bar insertion processing and outer casing reinforcement improve the support strength of the connection node, thereby improving the reliability of the connection between the beam and the column, improving the overall stability of the steel structure. When bearing load, the beam and column are less likely to deform or be damaged, improving the safety of the overall structure. Moreover, the crossbeam installation gap makes it easy for the crossbeam to be the same width as the side wall of the column after installation, improving the aesthetics of the crossbeam and the column after installation.

[0025] The four side walls of the column 1 are each provided with a number of steel reinforcement bodies 12, which surround the exterior of the second connecting beam 7 and the first connecting beam 4.

[0026] Both ends of the surfaces of the multiple reinforcing bar bodies 12 corresponding to the second connecting beam 7 are fitted with second crossbeam connecting parts 9 that cover the outside of the two ends of the second connecting beam 7. Both ends of the surfaces of the multiple reinforcing bar bodies 12 corresponding to the first connecting beam 4 are fitted with first crossbeam connecting parts 8 that cover the outside of the two ends of the first connecting beam 4. The outer surface width of the second crossbeam connecting parts 9 and the first crossbeam connecting parts 8 is smaller than the width of the corresponding side wall of the column 1 to form a crossbeam installation gap.

[0027] The first connecting beam 4 penetrates the interior of the column 1, and the second connecting beam 7 successively penetrates the interior of the column 1 and the first connecting beam 4, forming a connecting support node. After multiple steel bars 12 are inserted, they are combined with the outer casing of the second crossbeam connecting part 9 and the first crossbeam connecting part 8. The steel bars 12 are inserted and reinforced by the outer casing to improve the support strength of the connecting node, thereby improving the reliability of the connection between the beam and the column, improving the overall stability of the steel structure, and making it less likely for the beam and column to deform or be damaged when bearing loads, thus improving the safety of the overall structure.

[0028] The installation gap of the crossbeam ensures that the width of the crossbeam is the same as that of the side wall of column 1 after installation, thus improving the aesthetics of the crossbeam and column 1 after installation.

[0029] Furthermore, the front and rear sides of the column 1 are provided with second openings 3 that are adapted to the first connecting beam 4. The second openings 3 facilitate welding work after the first connecting beam 4 passes through the column 1.

[0030] Furthermore, one end face of the column 1 and the other end face are provided with a first opening 2 that is adapted to the second connecting beam 7, and the surface of the first connecting beam 4 is provided with a through opening 5 that is adapted to the second connecting beam 7. The first opening 2 and the through opening 5 facilitate the welding work after the second connecting beam 7 passes through the first connecting beam 4 and the column 1.

[0031] Furthermore, when the second connecting beam 7 penetrates the interior of the through opening 5, the top of the second connecting beam 7 is flush with the top of the first connecting beam 4, and a connecting plate 6 located inside the column 1 is welded between the top of the second connecting beam 7 and the top of the first connecting beam 4.

[0032] Furthermore, the side walls of the second connecting beam 7, the first connecting beam 4, and the column 1 are all provided with several insertion holes 13 that are adapted to the steel reinforcement body 12.

[0034] In this embodiment, after the second crossbeam connecting part 9 is sleeved on the outside of the second connecting beam 7, it can be welded to the second reinforcing plate 11 filled between them to improve the connection strength between the second crossbeam connecting part 9 and the second connecting beam 7.

[0035] After the first crossbeam connecting part 8 is sleeved on the outside of the first connecting beam 4, it can be welded to the first reinforcing plate 10 filled between them to improve the connection strength between the first crossbeam connecting part 8 and the first connecting beam 4.

[0036] Furthermore, the top of both the second crossbeam connecting part 9 and the first crossbeam connecting part 8 are provided with a number of mounting holes 14, which facilitate the horizontal connection and fixation with the second crossbeam connecting part 9 or the first crossbeam connecting part 8.

[0037] The working principle and usage process of this utility model are as follows: After the utility model is installed, the first connecting beam 4 penetrates the interior of the column 1, and the second connecting beam 7 successively penetrates the interior of the column 1 and the first connecting beam 4 to form a connecting support node. After multiple steel bar bodies 12 are inserted, they are combined with the outer sleeve of the second crossbeam connecting part 9 and the first crossbeam connecting part 8. The steel bar bodies 12 are inserted and reinforced by the outer sleeve to improve the support strength of the connecting node, thereby improving the reliability of the connection between the beam and the column. The crossbeam installation gap is designed to make the crossbeam and the side wall width of the column 1 the same after installation, thus improving the aesthetics between the crossbeam and the column 1 after installation.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
