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 an open steel component. Background Technology

[0002] Closed-section steel components, also known as box-type steel components, have a cross-section shaped like a "□" and are commonly used elements in building structures. In contrast, open-section steel, such as I-beams and H-beams, are also common components in building assembly.

[0003] Currently, the side connection method for closed-section steel components typically employs a method of end plates plus connecting plates to achieve side fixation at the ends. For example, the box-shaped steel column connection structure disclosed in Chinese Patent Publication No. CN204081085U includes a steel frame and a connection structure. The steel frame consists of four angle steels, multiple end plates, and multiple sets of high-strength bolts, while the connection structure includes multiple connecting plates, which are combined to form a cuboid.

[0004] However, in practical applications, this assembly structure using end plates and connecting plates exhibits relatively weak torsional resistance, and may not be sufficient to meet structural safety requirements after actual assembly and connection with open steel sections. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies, such as the relatively weak torsional resistance of assembly structures using end plates and connecting plates, and to propose a connection node between the end of a closed steel component and the side of an open steel component.

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

[0007] Design a connection node between the end of a closed steel member and the side of an open steel member, including an open steel member and a closed steel member connected to the side of the open steel member;

[0008] A connecting plate is provided between the open-section steel and the closed-section steel by fasteners. There are two connecting plates, which are respectively connected to the two side ribs of the open-section steel.

[0009] The open-section steel also has an operating hole, and a reinforcing component is fixedly installed on the inner side of the open-section steel.

[0010] Furthermore, the two connecting plates are arranged opposite to each other and fixed to the inner or outer surface of the closed-section steel.

[0011] Furthermore, the reinforcing component includes a first plate and a second plate that are vertically connected. The first plate is connected to the open steel section by a locking member, and the second plate is connected and fixed to the fastener. A reinforcing rib is also fixedly connected between the first plate and the second plate.

[0012] Furthermore, the end of the closed-section steel is spaced a predetermined distance from the web of the open-section steel, and a portion of the first plate is inserted into the predetermined distance.

[0013] Furthermore, it also includes an expansion opening at the end of the closed steel section, the expansion opening extending to the side of the closed steel section.

[0014] Furthermore, the expansion opening is a semi-circular opening, and two expansion openings are opened opposite each other on the upper and lower plates of the closed steel section.

[0015] Furthermore, the end of the closed-section steel is spaced at a predetermined distance from the web of the open-section steel, and a welded component fixed to both the closed-section steel and the open-section steel is provided within this predetermined distance.

[0016] The present invention proposes a connection node for the end of a closed-section steel member and the side of an open-section steel member. The advantages are as follows: By using a connecting plate to connect the closed-section steel and the open-section steel, the connection requirements for both side hinges and rigid connections can be met, improving the applicability of assembly. This connection design significantly enhances the torsional and shear resistance of the closed-section steel end. Furthermore, with the addition of specially designed reinforcing components, the connection strength is further enhanced, optimizing the overall torsional and shear resistance. This structural design is reliable, easy to install, and better meets the needs of closed-section steel members in engineering applications. 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 an embodiment of this utility model, a side connection node between the end of a closed steel member and the side of an open steel member is disclosed. This side connection node is used to solve the problem of insufficient torsional and shear resistance of the current closed steel member when it is side-connected. Specifically, in this embodiment, the side of the closed steel member is hinged to the open steel member. It should be noted that the open steel member mentioned in this embodiment includes, but is not limited to, I-beams or H-beams.

[0028] Specifically, the node structure includes an open steel section 1 and a closed steel section 2 connected to the side of the open steel section 1. Specifically, the closed steel section 2 can be set at the same height as the top of the open steel section 1 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 further here.

[0029] A connecting plate 4 is provided between the open-section steel 1 and the closed-section steel 2 by fasteners 3. Two connecting plates 4 are provided and are respectively connected to the two side ribs of the open-section steel 1. (Refer to...) Figure 2 or Figure 3 As shown, the connecting plate 4 can be connected to the inner or outer sides of the two side ribs of the open steel profile 1.

[0030] The open-section steel 1 also has an operating hole 11. A reinforcing component 5 is fixedly installed on the inner side of the open-section steel 1. In this preferred embodiment, the operating hole 11 is set as a round hole so that bolts and other parts can be placed between the two connecting plates 4 during the assembly process, thereby increasing the operating space.

[0031] In some embodiments, the two connecting plates 4 are arranged opposite to each other and fixed on the inner or outer surface of the closed steel section 2. Specifically, the connecting plate 4 is in contact with the wall of the closed steel section 2. Preferably, the thickness of the connecting plate 4 in this embodiment should be 2 mm greater than the web thickness of the closed steel section 2. The connecting plate 4 is laid out and installed in the factory. The position of the connecting plate 4 can be on the inner or outer side of the web of the closed steel section 2, and can be determined according to the convenience of construction.

[0032] Furthermore, in this embodiment, the reinforcing component 5 includes a first plate 51 and a second plate 52 connected vertically. The first plate 51 is connected to the open steel section 1 by a locking member 53, and the second plate 52 is connected and fixed to the fastener 3. Preferably, in this embodiment, both the fastener 3 and the locking member 53 are set as torsion-shear type high-strength bolts to improve the torsion-shear resistance of the connection. In this embodiment, a reinforcing rib 54 is also fixedly connected between the first plate 51 and the second plate 52. In addition, it should be further noted that in this embodiment, the first plate 51, the second plate 52 and the reinforcing rib 54 form a triangular frame structure. This structure is designed to reinforce the connection between the open steel section 1 and the closed steel section 2, and also to reinforce the operating hole 11, thereby further improving the torsion-shear resistance of the connection between the two. It should be noted that the reinforcing component 5 should be able to enter through the operating hole 11 for subsequent installation.

[0033] Based on the above embodiments, in this embodiment, the end of the closed-section steel 2 is spaced a predetermined distance from the web of the open-section steel 1, and a portion of the first plate 51 is inserted into the predetermined distance. Since the connecting plate 4 can be connected to the inner or outer side of the side rib of the open-section steel 1, there are two possible installation scenarios for the first plate 51 in this embodiment, such as... Figure 2 As shown, when the two connecting plates 4 are connected between the side ribs of the open steel section 1, the second plate 52 is attached to the inner wall of the closed steel section 2, and a portion of its first plate 51 stops at the end of the closed steel section 2 to enhance the shear resistance.

[0034] like Figure 3 As shown, when the two connecting plates 4 are connected to the outside of the side rib of the open steel 1, holes can be opened on the side rib of the open steel 1, and a part of the first plate 51 passes through the hole and stops at the end of the closed steel 2, thus achieving the effect of enhancing the shear resistance of the connection between the two.

[0035] Furthermore, this embodiment also includes an expansion opening 21 at the end of the closed steel section 2. The expansion opening 21 extends to the side of the closed steel section 2. When the cross-sectional width of the closed steel section 2 is greater than 350mm, the expansion opening 21 can be opened on the closed steel section 2, thereby improving the ease of bolt installation.

[0036] Based on the above embodiments, in this embodiment, the expansion opening 21 is a semi-circular opening, and two expansion openings 21 are opened opposite each other on the upper and lower plates of the closed steel 2.

[0037] Example 2

[0038] In this embodiment, the similarities with Embodiment 1 will not be repeated. The difference is that this embodiment takes the lateral rigid connection of the closed steel structure as an example. Of course, in this embodiment, the closed steel 2 can be set at the top of the open steel 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 are omitted here.

[0039] The end of the closed steel section 2 is spaced at a predetermined distance from the web of the open steel section 1. A welded component 6 is provided within this predetermined distance to fix the closed steel section 2 and the open steel section 1. Specifically, in this embodiment, the two sides of the closed steel section 2 that are not connected to the connecting plate 4 are reinforced and fixed by the welded component 6, thus achieving a rigid connection of the sides of the closed steel section 2. Preferably, the welded component 6 in this embodiment is a plate.

[0040] Example 3

[0041] The embodiments described above all use the example of the closed-section steel 2 being inserted into the inner side of the open-section steel 1. This embodiment is a further improvement on the first embodiment, specifically, as follows: Figure 7 As shown, the side of the open-section steel 1 is extended to form an extension, and the closed-section steel 2 is connected to the extension and connected by fasteners 3. Of course, the reinforcing component 5 also extends to the outside of the open-section steel 1 to connect the closed-section steel 2.

[0042] In summary, this utility model, by using a connecting plate 4 to connect the closed steel section 2 and the open steel section 1, can meet the connection requirements of both side hinged and rigid connections, improving the applicability of assembly. This node connection design significantly improves the torsional and shear resistance of the end of the closed steel section 2. In addition, with the help of specially designed reinforcing components 5, 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 steel section components in engineering applications.

[0043] 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.
