Description

Technical Field

[0001] This utility model relates to the technical field of steel structure connection nodes in building structures, and more specifically to a circular tube core composite stiffened multidirectional I-beam connection node. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are primarily composed of steel beams, columns, trusses, and other components made of shaped steel and steel plates, and undergo rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, they are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields. Steel structures are prone to corrosion, and generally require rust removal, galvanizing, or painting, as well as regular maintenance. The development and application of new prefabricated steel structure systems are of great significance to the industrialization of structural engineering.

[0003] The multi-directional I-beam connection nodes used in existing engineering practices suffer from problems such as stress concentration, insufficient stiffness, and complex construction, which affect the performance of steel structures.

[0004] Therefore, how to provide an I-beam connection node structure that can achieve rapid on-site installation and precise positioning of I-beams at multiple angles, and improve the bearing capacity and stress distribution uniformity under multi-directional loads, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a circular tube core composite stiffening multi-directional H-beam connection node. Through the composite stiffening structure of the central circular tube and the radial node web, combined with the upper and lower parallel node plates to form a rigid core area, the bearing capacity and stress distribution uniformity of the H-beam under multi-directional loads are significantly improved. At the same time, through the modular connection design of the end plates and the H-beam (welded or assembled bolt fixing), rapid on-site installation and precise positioning of the H-beam at multiple angles are achieved, solving the technical bottlenecks of poor spatial adaptability and long construction cycle of traditional nodes.

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

[0007] A circular tube core composite stiffened multidirectional I-beam connection node includes a circular tube core area and an I-beam;

[0008] The core area of ​​the circular tube includes a circular tube, node webs, and node plates; multiple node webs are provided, which are radially arranged relative to the central axis of the circular tube and one end of each node web is fixed to the outer wall of the circular tube; two node plates are provided, and their panels are respectively fixed to both ends of the circular tube; multiple I-beams are provided, and one end of each I-beam is welded and fixed to the edge of the multiple node webs and node plates.

[0009] The beneficial effects of this utility model are that multiple node web plates are radially fixed to the outer wall of the circular tube to form a composite stiffening structure, two node plates are fixed at both ends of the circular tube and welded to the web plates to form a rigid circular tube core area, and the I-beam is fixed to the web plates. This structure can significantly improve the bearing capacity and stress distribution uniformity of the I-beam.

[0010] Preferably, the two node plates are fixed parallel to each other at both ends of the circular tube; the face plate of the node plate is welded to the web plate and the upper or lower edge of the I-beam by fillet weld. The circular tube, node plates, web plate, and I-beam are welded together to form a stable node structure.

[0011] Preferably, the faceplates of the node plates are arranged parallel to the cross-section of the circular tube, and the faceplates of the two node plates cover the upper and lower edges of the node web. The node plates are welded to the node web across the entire cross-section, ensuring the structural strength of the core area of ​​the circular tube.

[0012] Preferably, an end plate is welded to one end of the upper and lower flanges of the I-beam, and the end plate is welded and fixed to the node web and the node plate. The I-beam and the end plates are welded and fixed to form a modular structure, and the end plates can ensure the precise positioning of the I-beam.

[0013] Preferably, the end plate's face panel is arranged perpendicular to the face panel of the node web; the width of the end plate is equal to the width of the I-beam flange. By arranging the end plate and node web face panel perpendicularly, the welding difficulty between the node web and the end is reduced, improving construction efficiency.

[0014] Preferably, the thickness of the end plate is at least 1.2 times greater than the greater thickness of the node plate or the flange plate of the I-beam. This ensures the connection strength between the I-beam and the core area of ​​the circular tube, improving the quality of the joint.

[0015] Preferably, the face plate of the node web is arranged parallel to the web of the I-beam; the included angle between two adjacent node webs is not less than 30°. This ensures sufficient installation space for the I-beams and prevents mutual interference between adjacent I-beams.

[0016] Preferably, the included angle α between the flange of the I-beam and the panel of the gusset plate is 0–15°. This allows for multi-angle spatial arrangement of the I-beam outside the plane of the gusset plate.

[0017] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a circular tube core composite stiffening multi-directional H-beam connection node. Through the composite stiffening structure of the central circular tube and the radial node web, combined with the upper and lower parallel node plates to form a rigid core area, the bearing capacity and stress distribution uniformity of the H-beam under multi-directional loads are significantly improved. At the same time, through the modular connection design of the end plates and the H-beam, rapid on-site installation and precise positioning of the H-beam at multiple angles are achieved, solving the technical bottlenecks of poor spatial adaptability and long construction cycle of traditional nodes.

The composite stiffening structure of the core area of ​​the circular tube is used to improve the bearing capacity and stress distribution uniformity of the I-beam under multi-directional loads.

[0029] In this embodiment, two node plates 2 are fixed vertically and horizontally at both ends of the circular tube 1; the face plate of the node plate 2 is welded to the upper or lower edge of the node web plate 3 and the I-beam 4 by fillet weld.

[0031] The panel of the node plate is arranged perpendicular to the panel of the node web and completely covers the node web, that is, the edge of the panel of the node plate is flush with the edge of the web, which ensures the overall performance of the core area of ​​the circular tube.

[0032] In this embodiment, end plates 5 are welded to one end of the upper and lower flanges of the I-beam 4, and the end plates 5 are welded and fixed to the node web 3 and the node plate 2.
