Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a connection node between the end of a closed steel component and the side of a closed steel component. Background Technology

[0002] Closed-section steel members, also known as box-type steel members, are structural elements with a cross-section shaped like a "□". Due to their unique closed structure, closed-section steel members exhibit excellent bending and torsional stiffness, and are therefore widely used in applications requiring high structural stability.

[0003] Currently, the side connection method for closed steel components generally involves using a head plate and a connecting plate at the end of the closed steel component to achieve side connection and fixation. For example, a prefabricated beam-column connection node for metal structure systems disclosed in Chinese Patent Publication No. CN115405000A includes a beam, a column, a head plate, a fastener, and a connecting plate; the head plate is fixed to the top of the column; the fastener is fixed to the top of the column and located above the head plate; the connecting plate is set on the fastener and bolted to the beam.

[0004] However, in practical applications, it has been found that the torsional resistance of the assembly structure using end plates and connecting plates is relatively weak, which may not be sufficient to meet the structural safety requirements in some application scenarios. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing connection structures, such as relatively weak torsional resistance, and to propose a closed-end steel member and closed-side steel member connection node.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a connection node between the end and side of a closed-section steel member, including:

[0008] The main box column and the side connecting box column located on the main box column are provided. Two connecting plates are also fixedly installed on the outside of the main box column. The connecting plates are connected and fixed to the connecting box column by fasteners.

[0009] A reinforcing component is provided between the connecting plate and the connecting box column, and an operating hole is also provided on at least one of the upper surfaces of the connecting box column.

[0010] Furthermore, the two connecting plates are arranged opposite each other and horizontally, with the two connecting plates located on the inner or outer side of the connecting box column, and the connecting plates and the connecting box column having their walls in contact.

[0011] Furthermore, the reinforcing component includes a reinforcing plate, which has a Z-shaped structure;

[0012] The bending part of the reinforcing plate fits into the end of the connecting plate, and the two horizontal surfaces are respectively attached to the connecting box column and the connecting plate.

[0013] Furthermore, one horizontal surface of the reinforcing plate is connected to the connecting plate via the fastener, and the other horizontal surface is connected to the connecting box column via a locking member.

[0014] Furthermore, the operating hole is an arc-shaped opening on the upper and lower abdominal surfaces of the connecting box column, with the two arc-shaped openings facing each other and both extending to the outer edge of the connecting box column.

[0015] Furthermore, the operating hole is a circular hole formed on the upper and lower surface of the connecting box column, with the two circular holes facing each other vertically.

[0016] Furthermore, the edge of the connecting box column away from the connecting plate is welded to the main box column.

[0017] This invention proposes a connection node for the end and side of a closed-section steel member. The advantages are as follows: By installing two connecting plates at corresponding positions on the main box column, the connecting plates are effectively connected to the web of the connecting box column. Operating holes are provided on the upper and lower flanges of the connecting box column to facilitate the installation of bolts and other fasteners. This connection design significantly improves the torsional and shear resistance of the end of the connecting box column. Furthermore, with the addition of specially designed reinforcing components, the connection strength is further enhanced, and the overall torsional and shear resistance is optimized. This structural design is reliable, easy to install, and better meets the needs of closed-section steel members in engineering applications. It also supports both rigid and hinged side connections, making it more versatile. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Reference Figure 1-3 As one embodiment of this utility model, a connection node between the end of a closed-section steel member and the side of the closed-section steel member is disclosed. This side connection structure is used to solve the insufficient torsional and shear resistance of current side connection structures of closed-section steel members. Specifically, this embodiment takes the lateral hinged connection of the closed-section steel structure as an example, and it specifically includes:

[0028] The main box column 1 and the side connecting box column 2 located on the main box column 1. Specifically, the connecting box column 2 can be set at the top of the main box 1 at the same height or at other positions. In this embodiment, the diagram is illustrated at the same height. Other height positions can use the same connection method, which will not be elaborated here.

[0029] In this embodiment, two connecting plates 3 are also fixedly installed on the outside of the main box column 1, and the connecting plates 3 are connected and fixed to the connecting box column 2 by fasteners 4;

[0030] A reinforcing component 5 is provided between the connecting plate 3 and the connecting box column 2, and an operating hole 21 is also provided on at least one of the upper surfaces of the connecting box column 2.

[0031] like Figure 2 and Figure 3 As shown, in some embodiments, the two connecting plates 3 are arranged opposite each other and horizontally, wherein the two connecting plates 3 are located on the inner or outer side of the connecting box column 2, and the connecting plates 3 are in contact with the wall of the connecting box column 2. Preferably, in this embodiment, the thickness of the connecting plate 3 should be 2 mm greater than the thickness of the web of the connecting box column 2. The connecting plates 3 can be laid out and installed in the factory, and the position of the connecting plates 3 can be on the inner or outer side of the web of the connecting box column 2, which can be determined according to the convenience of construction.

[0032] Furthermore, the reinforcing component 5 in this embodiment includes a reinforcing plate, which has a Z-shaped structure;

[0033] The bending part of the reinforcing plate fits into the end of the connecting plate 3, and the two horizontal surfaces are respectively attached to the connecting box column 2 and the connecting plate 3.

[0034] Based on the above embodiments, one horizontal surface of the reinforcing plate is connected to the connecting plate 3 via the fastener 4, and the other horizontal surface is connected to the connecting box column 2 via the locking member. In this embodiment, both the fastener 4 and the locking member are set as torsion-shear type high-strength bolts to improve the torsion-shear resistance at the connection. In addition, the reinforcing plate can further improve the connection strength between the main box column 1 and the connecting box column 2, thereby further improving the torsion-shear resistance of the connection between the two.

[0035] In some embodiments, the operating hole 21 in this invention is an arc-shaped opening formed on the upper and lower abdominal surfaces of the connecting box post 2. The two arc-shaped openings are opposite each other and both extend to the outer edge of the connecting box post 2. Specifically, in this embodiment, the arc-shaped openings are used to provide an operating channel when installing the fastener 4. That is, during installation, the user can place the fastener 4 or the reinforcing plate inside the connecting box post 2 through the arc-shaped openings. The specific size of the arc-shaped openings can be designed according to actual needs and is not limited here.

[0036] Example 2

[0037] Reference Figure 4-6 The similarities between this embodiment and Embodiment 1 will not be repeated here. The difference is that this embodiment takes the closed-type steel structure with lateral rigid connection as an example. Of course, in this embodiment, the connecting box column 2 can be set at the top of the main box column 1 at the same height or other positions. This embodiment uses the same height position for illustration. Other height positions can use the same connection method. Further details will not be provided here.

[0038] Specifically, in this embodiment, the operating hole 21 is a circular hole opened on the upper and lower surface of the connecting box column 2, with the two circular holes facing each other vertically.

[0039] In addition, to achieve a rigid connection, in this embodiment, the edge of the connecting box column 2 away from the connecting plate 3 is welded to the main box column 1.

[0040] In this real-time exchange rate, two connecting plates 3 are used to connect and fix the two sides of the connecting box column 2. The other two sides are welded together to fix the main box column 1 and the connecting box column 2, thus achieving a rigid connection of the sides of the connecting box column 2. Secondly, since the other two sides of the connecting box column 2 should be welded in this embodiment, it is not advisable to start with an arc-shaped opening. Therefore, in this embodiment, round holes are opened on the upper and lower surfaces of the connecting box column 2 to enable the operation of the fasteners 4 and the reinforcing plates.

[0041] In summary, this invention achieves effective connection between the connecting plates 3 and the web of the connecting box column 2 by installing two connecting plates 3 at corresponding positions on the main box column 1. Operating holes 21 are provided on the upper and lower flanges of the connecting box column 2 to facilitate the installation of bolts and other fasteners. This node connection design significantly improves the torsional and shear resistance of the end of the connecting box column 2. Furthermore, the specially designed reinforcing components 5 further enhance the connection strength and optimize the overall torsional and shear performance. This structural design is reliable, easy to install, and better meets the needs of closed-section steel components in engineering applications.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
