Embodiment 1

[0026] Embodiment 1: as figure 1 , figure 2 , image 3 with Figure 4 As shown, an inclusive round pipe intersecting node and its manufacturing method are carried out according to the following steps:

[0027] (1) Structural combination:

[0028] Including the main pipe 1 and the secondary pipe 2, the main pipe 1 and the secondary pipe 2 are respectively arc-shaped steel pipes, the outer wall of the secondary pipe 2 is provided with an intersecting opening 3, and the main pipe 1 is half-embedded in the intersecting opening 3;

[0029] (2), production process:

[0030] (1) First, the digital simulation of the secondary pipe is divided into two sections, divided into secondary pipe 1 and secondary pipe 2, and a twisted intersecting opening in the middle of the pipe that cannot be cut is converted into two intersecting openings at the end of the pipe that can be cut by CNC , and issue the arc tube CNC cutting data of secondary tube 1 and secondary tube 2;

[0031] (2), the...

Abstract

The invention relates to a tubular joint, in particular relates to a containment type tubular joint for a round tube and a manufacturing method of the tubular joint and belongs to the field of steel structures. The tubular joint comprises a primary tube and a secondary tube, wherein the primary tube and the secondary tube are respectively arc-shaped steel tubes; a tubular opening is formed in the outer wall of the secondary tube; and the primary tube is semi-embedded into the tubular joint. According to the containment tubular joint for the round tube and the manufacturing method of the tubular joint, the structure is compact, the stress performance is outstanding, and the manufacturing method is scientific.

Description

technical field [0001] The invention relates to an intersecting joint, in particular to an inclusive circular pipe intersecting joint and a manufacturing method, belonging to the field of steel structures. Background technique [0002] In recent years, with the improvement of architectural design level and the development of processing equipment, the theoretical and technical research of new long-span space tube truss structures has also been further developed. Round steel pipes have good cross-sectional geometric properties, good compressive and bending and torsional bearing capacity, closed pipes are not easy to corrode, and the building has a beautiful appearance. Therefore, the pipe truss structure is favored by designers for its unique advantages. [0003] Chinese patent 201010219122.1 discloses a plug-in welded intersecting joint, including a main pipe, a branch pipe and an ear plate. The branch pipe is connected to the main pipe through a fillet weld. The groove is i...
