Description

Technical Field

[0001] This utility model relates to the technical field of three-dimensional steel structure spatial nodes for tower crowns in building structures, and more specifically to a composite three-dimensional steel structure connection node for tower crowns. Background Technology

[0002] With the rapid development of society and the economy, people's living standards and quality of life are constantly improving, and the pace of life, both in production and daily life, is accelerating, including in the construction industry. Currently, most offices and residences are constructed using concrete. We all know that concrete construction has a long construction period and is heavily influenced by weather, especially in winter. We see many construction sites halting work after temperatures drop below zero, further extending the construction period. Furthermore, concrete construction requires a wide variety of trades, including skilled laborers, carpenters, and bricklayers, demanding high-level skills. The increasing costs of materials and labor lead to higher overall construction costs and greater investment. Additionally, as people's demands for quality of life and work increase, more and more young people are unwilling to work in the construction industry. These factors have spurred the development of steel structure buildings.

[0003] Currently, many steel structure projects have adopted novel and unique styles in pursuit of aesthetics and distinctive designs. To meet load-bearing requirements, this has resulted in highly complex and unusual structural nodes. Fabricating these complex structures and nodes presents significant challenges. Therefore, improving the efficiency of fabricating irregularly shaped components is imperative. In this context, steel structure fabrication technologies that can effectively ensure the fabrication of steel components, improve efficiency, and shorten construction time have enormous potential for development.

[0004] A tower crown is usually the top structure of a building, and it is typically located at a high position. Traditional tower crown steel structure nodes suffer from problems such as insufficient spatial stiffness and significant stress concentration under complex three-dimensional loads.

[0005] Therefore, how to provide a tower crown node structure that can achieve advantages such as uniform stress distribution, high bearing capacity and strong spatial adaptability in the tower crown node area, and meet the requirements of complex stress and efficient construction, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the present invention provides a composite three-dimensional tower crown steel structure connection node, which aims to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A composite three-dimensional tower crown steel structure connection node, comprising:

[0009] A support assembly, comprising a steel pipe column, wherein a slot is provided on the upper end wall of the steel pipe column;

[0010] A connecting assembly includes a node plate and multiple connecting plates; the node plate is inserted into the slot at its center and welded to the steel pipe column; both ends of the node plate extend outward along the outer wall of the steel pipe column relative to its slot; one end of each of the multiple connecting plates is welded to the outer wall of the steel pipe column.

[0011] An I-beam assembly, comprising a main beam and multiple secondary beams; one end of the main beam is welded to the outer wall of the steel pipe column; one end of each of the multiple secondary beams is screwed or welded to the end of a multiple connecting plate away from the steel pipe column.

[0012] The beneficial effects of this utility model are that the connection node of the tower crown steel structure takes the steel pipe column as the core, and the main beam and the secondary beam are directly welded and fixed to the steel pipe column. The relative hinge between the secondary beam and the steel pipe column can be realized through the connection plate. By utilizing the stress distribution of the node plate, this utility model has the advantages of uniform stress distribution in the node area, high bearing capacity and strong spatial adaptability.

[0013] Preferably, the support assembly further includes two diagonal bracing tubes, one end of which is welded and fixed to both sides of the lower end of the node plate. The two diagonal bracing tubes and the steel pipe column form a triangular support system, which has stronger stability and higher load-bearing capacity.

[0014] Preferably, the angle α between the axis of the inclined bracing tube and the axis of the steel pipe column is 60° to 90°.

[0015] Preferably, the two diagonal bracing tubes are arranged symmetrically with respect to the axis of the steel pipe column.

[0016] Preferably, the upper end of the bracing pipe has a bevel, and the lower end of the node plate is inserted into the bevel and welded in place. The bracing pipe and the connecting plate are connected by a full-fusion bevel welding method, which simplifies construction and ensures a stable and reliable connection.

[0017] Preferably, the connecting assembly further includes stiffening ribs; the node plate has a slot on its panel inside the steel pipe column, the stiffening rib's surface is inserted into the slot, and both ends are welded and fixed to the inner wall of the steel pipe column; the panels of the stiffening rib and the node plate are arranged perpendicularly to each other. The stiffening rib supports the node plate on the steel pipe column, ensuring the strength and stability of the node plate, and providing higher load-bearing capacity.

[0018] Preferably, the thickness of the node plate, connecting plate and stiffening rib plate is not less than 2cm.

[0019] Preferably, there are two connecting plates, which are symmetrical on both sides of the main beam, and the angle β between the surface of the connecting plate and the surface of the web of the main beam is 30° to 90°.

[0020] Preferably, the wall thickness of the steel pipe column is not less than 6mm. This ensures the supporting performance of the steel pipe column.

[0021] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a composite three-dimensional tower crown steel structure connection node, which takes steel pipe column as the core, combines double diagonal bracing pipe and multi-directional I-beam components, and integrates stiffening rib plate and node plate. It has the advantages of uniform stress distribution in node area, high bearing capacity and strong spatial adaptability, and can meet the needs of complex stress and efficient construction.

[0031] Participate in the attached Figures 1-3 This utility model discloses a composite three-dimensional tower crown steel structure connection node, including:

[0032] Support component 1, which includes a steel pipe column 11, with a slot provided on the upper end of the pipe wall of the steel pipe column 11;

[0033] The connecting component 3 includes a node plate 31 and multiple connecting plates 32; the node plate 31 is inserted into a bayonet in the middle and welded and fixed to the steel pipe column 11, and both ends of the node plate 31 extend outward along the outer wall of the steel pipe column 11 relative to its bayonet; one side of the multiple connecting plates 32 is welded and fixed to the outer wall of the steel pipe column 11.

[0035] like Figure 1 and 2 As shown, two opposing bayonets are opened on the upper end of the steel pipe column. The middle plate of the node plate is inserted into the bayonets. The panel of the node plate is connected to the pipe wall of the steel pipe column opposite the bayonets by a full penetration bevel welding method, which makes the connection more stable and effective.

[0036] The main beam and two secondary beams adopt an orthogonal or oblique three-dimensional layout. One end of the upper and lower flange plates of the main beam is connected to the outer wall of the steel pipe column by a full penetration circumferential weld, and one end of the web plate of the main beam is connected to the outer wall of the steel pipe column by a T-shaped continuous fillet weld. The connecting plate is welded to the outer wall of the steel pipe column by double-sided fillet welds. The web plate of the secondary beam is connected to the connecting plate by assembled high-strength bolts or fillet welds welded on site.

[0037] To further optimize the above technical solution and ensure the stable support of the steel pipe column for the connecting components and I-beam components, as well as its higher load-bearing capacity, the support component 1 also includes two diagonal bracing pipes 12. One end of each diagonal bracing pipe 12 is welded and fixed to both sides of the lower end of the node plate 31. The two diagonal bracing pipes 12 are arranged symmetrically with respect to the axis of the steel pipe column 11.
