Description

Technical Field

[0001] The utility model relates to the technical field of drum-shaped nodes, in particular to a small-angle multi-section intersecting drum-shaped node of a blade tube truss. Background Art

[0002] The tube truss structure is generally made of circular steel tubes connected by end welding, and the connection is called intersection. Under normal circumstances, the tube truss node is connected by a main tube and multiple secondary tubes. However, as the steel structure shape becomes more and more novel, the intersection and intersection of the tube truss becomes more and more complex.

[0003] After searching, the Chinese patent with publication number CN204252287U discloses a drum-shaped connection node of a steel structure truss structure, which is composed of a drum-shaped ring, a broken line chord, a radial support and a web. The drum-shaped ring is a cylinder, and the broken line chord, the radial support and the web are connected to the drum-shaped ring by welding. A stiffening plate is arranged inside the drum-shaped ring, and the stiffening plate is fully penetrated and welded to the drum-shaped ring. The utility model is a new type of node form of a large-span space steel pipe structure, which is regarded as a derivative node of a steel pipe intersecting node and a welded spherical node.

[0004] Based on the above search combined with the existing technology, we found that;

[0005] Although the above-mentioned search patent is a derivative node of the steel pipe intersecting node and the welded spherical node, it cannot solve the problem of the intersecting connection of multiple tubes with different diameters at a small angle in the blade plane and the welding connection of the intersecting node of multiple components of steel pipes and steel sections, so it has certain limitations. Utility Model Content

[0006] In order to solve the above technical problems, the utility model proposes a small-angle multi-section intersecting drum-shaped node for a blade tube truss, which solves the problem of intersecting connection of multiple tubes with different diameters at small angles in a plane and welding connection of intersecting nodes of multiple components of steel pipes and steel sections.

[0007] The technical solution to achieve the purpose of the utility model is: a blade tube truss small-angle multi-section intersecting drum-shaped node, including a convergence component one, the side section of the convergence component one is fixedly connected to the convergence component two; the bottom end of the convergence component two is welded with a steel pipe one.

[0008] Preferably, a second steel pipe is welded to the bottom end of the intersection component one, and a pipe truss one is welded between the first steel pipe and the second steel pipe.

[0009] Preferably, a plurality of tube trusses 2 are welded to the surfaces of the steel pipe 1 and the steel pipe 2.

[0010] Preferably, stiffening plates are fixedly installed inside the steel pipe one and the steel pipe two.

[0011] Compared with the prior art, the present invention has the following significant advantages:

[0012] First: The utility model is aimed at the welding processing nodes of the blade hyperbolic tube truss at the intersection nodes of multiple diameter steel pipes and steel sections in the same curved surface, and is mainly suitable for the intersection connection of multiple pipes with different diameters at small angles in the plane, and the welding connection of the intersection nodes of multiple components of steel pipes and steel sections.

[0013] Secondly: the utility model reasonably improves the stress distribution of the steel pipe space truss node, avoids the stress concentration phenomenon in the node area, welds the stiffening plate inside the steel pipe, improves the structural stability of the device, and is beneficial to the welding between the branch pipe and the main pipe, thereby improving the endurance degree.

[0014] The invention solves the existing problem that it is impossible to connect multiple pipes with different diameters at a small angle in a plane and to weld and connect multiple components of steel pipes and section steel at intersecting nodes. BRIEF DESCRIPTION OF THE DRAWINGS
