Description

Technical Field

[0001] This utility model relates to the field of prefabricated steel structure technology, specifically to an assembly node with an adjustable angle for connecting H-shaped steel beams and columns and supports. Background Technology

[0002] Traditional H-beam-column and support connection nodes involve welding connecting plates to the H-beams or columns, causing the connecting plates to protrude outwards from the H-beam cross-section. This approach presents several problems: during packing, the protruding portion of the connecting plate necessitates increased packaging volume for complete assembly, resulting in significant waste of storage and transportation space, especially during long-distance transport and overseas shipping. Furthermore, the protruding portion of the connecting plate is susceptible to deformation from impacts during transport, affecting subsequent installation accuracy. Utility Model Content

[0003] This utility model proposes an adjustable assembly node for H-shaped steel beams and columns and supports. Its purpose is to solve the problem of transportation inconvenience caused by the existing connectors being welded to the H-shaped steel components, resulting in the connectors protruding from the cross-section of the steel components, and the problem of the connectors being easily damaged by collisions during transportation, which affects the subsequent installation accuracy.

[0004] The technical solution of this utility model is as follows:

[0005] An adjustable assembly node for an H-beam column and its support includes an H-beam column, a support, and a connector for connecting the two. The connector includes a third connecting plate bolted to the web of the H-beam column; a first connecting plate, parallel to the upper and lower flanges of the H-beam column, is vertically fixed at the middle position of the outer side of the third connecting plate; the outer side of the first connecting plate has an arc-shaped edge, and a connecting hole is provided in the central area of ​​the arc-shaped edge, through which the support and the first connecting plate are bolted.

[0006] As a further improvement, the connection hole is located on the outside of the flange of the H-shaped steel member.

[0007] As a further improvement, there are two first connecting plates, which are arranged symmetrically to the left and right along the length of the H-shaped steel member.

[0008] As a further improvement, a second connecting plate is also included, which is perpendicularly fixed to the first connecting plate and the third connecting plate respectively, and the outer side of the second connecting plate is chamfered.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] (1) This utility model uses standard connectors and H-shaped steel components for bolt connection. This detachable assembly design enables flush packaging, saves storage and transportation space, greatly improves transportation convenience, and reduces the risk of connector deformation due to collision. Moreover, this assembly method can avoid the weakening of the strength of the welding heat-affected zone, greatly improves the strength retention rate of the base material after the node is disassembled, and realizes reuse.

[0011] (2) This utility model achieves multi-angle installation of the support component through the symmetrical connecting parts on the top, bottom and left and right and the arc edge of the first connecting plate. There is no need to adjust the size according to the support angle, forming a standard part with uniform specifications, which significantly reduces the processing complexity and improves the versatility, and reduces the processing and customization cost.

[0018] The technical solution and effects of this utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0019] like Figures 1-4 An adjustable assembly node for an H-beam and column and its support is disclosed, comprising an H-beam 2 serving as the steel beam / column, a support 1, and a connector 3 for connecting the two. The connector 3 includes a third connecting plate 3-3 bolted to the web of the H-beam 2. The third connecting plate 3-3 and the web are connected by a matrix of double rows of bolts to form a composite shear surface, which can improve the shear strength of the node.

[0020] like Figure 1 and Figure 4A first connecting plate 3-1, parallel to the upper and lower wing plates, is vertically fixed at the middle position of the outer side of the third connecting plate 3-3. The outer side of the first connecting plate 3-1 has an arc-shaped edge, and a connecting hole is opened in the central area of ​​the arc-shaped edge. The support member 1 is bolted to the first connecting plate 3-1 through the connecting hole. The arc-shaped edge design ensures that the first connecting plate 3-1 can provide good strength support when the connecting member 3 is connected to the support member 1 at different angles.

[0021] To avoid interference from the H-beam steel member 2 during the installation of the support member 1, the connecting hole is opened on the outside of the wing plate of the H-beam steel member 2.

[0022] In this embodiment, the first connecting plate 3-1 consists of two sets, which are symmetrically arranged on the left and right sides along the length of the H-shaped steel member 2 to achieve double-sided support.

[0023] As another optional embodiment of this utility model, the first connecting plate 3-1 can be set separately to achieve unilateral support.

[0024] Furthermore, in order to provide sufficient connection strength, washers can be added when bolting the support 1 to the first connecting plate 3-1 to adjust the gap and disperse stress, thereby reducing stress concentration.

[0025] In this embodiment, as Figure 1 and Figure 3 The connector 3 further includes a second connecting plate 3-2, which is perpendicularly welded to the first connecting plates 3-1 on both sides and the third connecting plate 3-3 on the inner side, respectively, to enhance the overall connection strength. Furthermore, the outer side of the second connecting plate 3-2 is chamfered.

[0026] In this embodiment, the connector 3 is symmetrically designed in all directions, and the first connecting plate 3-1 has an arc edge, which can adapt to different force directions. Therefore, the support members 1 on both sides can be freely adjusted within a ±30° angle range without custom processing. It can be widely used as a standard part in different component connection scenarios.

[0027] In the workshop, the corresponding number of first connecting plates 3-1, second connecting plates 3-2, and third connecting plates 3-3 are cut and processed, and bolt holes are drilled. The first connecting plates 3-1, second connecting plates 3-2, and third connecting plates 3-3 are then welded and fixed to complete the fabrication of connector 3. During on-site installation, only the third connecting plate 3-3 of connector 3 needs to be bolted to the web of the H-beam steel component 2, and then the first connecting plate 3-1 needs to be bolted to the support component 1 to complete the node assembly.

[0028] It should be noted that, as will be apparent to those skilled in the art, this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. The scope of this utility model is defined by the claims rather than the foregoing description.
