[0002] Steel structure buildings break through the boundaries of real estate, construction and metallurgical industries, integrating them into a new industrial system. Compared with traditional concrete buildings, steel structure buildings use steel plates or steel sections instead of reinforced concrete, which have higher strength and better earthquake resistance. Since the components can be manufactured in the factory and installed on site, the construction period is greatly shortened. Steel can be reused, which can greatly reduce construction waste and is more environmentally friendly. Therefore, it is widely used in industrial and civil buildings. With the increasing number of steel structure buildings, some detailed problems have gradually emerged. For example, the splicing between supporting steel pipes, that is, the construction of supporting steel pipe splicing nodes.

[0009] In addition, a preferred structure is that the first weld is arranged along the length direction of the first steel pipe to be spliced; and the second weld is arranged along the length direction of the second steel pipe to be spliced.
[0010] In addition, a preferred structure is that the total length of the first weld and the second weld is greater than half the length of the liner steel pipe.

[0022] In response to the above, in the prior art, the nodes of the supporting steel pipes are constructed by flange plus bolt connection, ear plate positioning welding, and inserted partition welding. There are problems such as high production and installation precision requirements, long production and installation cycle, and increased construction cost. A supporting steel pipe splicing node structure is proposed.
[0023] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0024] In order to illustrate the supporting steel pipe splicing node structure provided by the utility model, Figure 1 The structure of the supporting steel pipe splicing node structure according to an embodiment of the utility model is shown; Figure 2 Shows Figure 1 The structure in the AA direction; Figure 3 The structure in which the supporting steel pipe is welded to the frame according to the embodiment of the utility model is shown.
[0025] like Figures 1 to 3 As shown together, the supporting steel pipe splicing node structure provided by the utility model includes: an inner lining steel pipe 1, a first weld 21 arranged on the first steel pipe 2 to be spliced, and a second weld 31 arranged on the second steel pipe 3 to be spliced; wherein, the butt end of the first steel pipe 2 to be spliced is sleeved on the outer periphery of one end of the inner lining steel pipe 1, and the first weld 21 corresponds to the position of the outer side wall of the inner lining steel pipe 1; the butt end of the second steel pipe 3 to be spliced is sleeved on the outer periphery of the other end of the inner lining steel pipe 1, and the second weld 31 corresponds to the position of the outer side wall of the inner lining steel pipe 1; the projection of the first weld 21 on the side wall of the first steel pipe 2 to be spliced and the projection of the second weld 31 on the side wall of the second steel pipe 3 to be spliced are butted in a Z shape.
[0026] Specifically, the inner diameter of the butt end of the first steel pipe 2 to be spliced is slightly larger than the outer diameter of the lining steel pipe 1, so when the butt end of the first steel pipe 2 to be spliced is sleeved on the outer periphery of one end of the lining steel pipe 1, the inner wall of the first steel pipe 2 to be spliced fits with the outer wall of the lining steel pipe 1; similarly, the inner diameter of the butt end of the second steel pipe 3 to be spliced is slightly larger than the outer diameter of the lining steel pipe 1, so when the butt end of the second steel pipe 3 to be spliced is sleeved on the outer periphery of the other end of the lining steel pipe 1, the inner wall of the second steel pipe 3 to be spliced fits with the outer wall of the lining steel pipe 1. At the site or processing site, the first steel pipe 2 to be spliced is welded to the lining steel pipe 1 through the first weld 21; the second steel pipe 3 to be spliced is welded to the lining steel pipe 1 through the second weld 31, thereby making the first steel pipe 2 to be spliced, the lining steel pipe 1, and the second steel pipe 3 to be spliced welded into an integrated structure. Due to the addition of the inner lining steel pipe 1, the welding of the three is made more convenient and faster; the accuracy requirements for welding butt and welding position positioning are reduced, and the projection of the first weld 21 on the side wall of the first steel pipe 2 to be spliced and the projection of the second weld 31 on the side wall of the second steel pipe 3 to be spliced are connected to form a Z-shaped structural design. The inner lining steel pipe 1 also serves as an arc-starting plate, which is easy to meet the requirements of equal strength connection and avoids the increased stress when the welds are in a straight line, thereby ensuring the welding quality. Therefore, the supporting steel pipe splicing node structure provided by the utility model has the advantages of short production cycle, convenient on-site connection, strong seismic performance, clear force, easy to ensure welding quality, low cost, etc.
[0027] The first weld 21 and the second weld 31 may be welded by groove penetration welding.
[0028] By correspondingly arranging the first weld 21 and the second weld 31 on the lining steel pipe 1 and the first steel pipe 2 to be spliced and the second steel pipe 3 to be spliced, the splicing accuracy between the steel pipes to be spliced is improved, the amount of on-site welding is small, and the welding quality requirements are easily met; the projections of the first weld 21 and the second weld 31 on the side walls of the first steel pipe 2 to be spliced and the second steel pipe 3 to be spliced are in a Z-shaped structural design, which avoids welding stress concentration and makes the structure safer and more complete; the utility model has the advantages of simple operation, fast construction speed, high installation accuracy, and reduced engineering cost.
[0029] As a preferred solution of the present invention, the first weld 21 and the second weld 31 are respectively located on two sides of the lining steel pipe 1 .
[0030] Specifically, the first weld 21 and the second weld 31 are preferably located on opposite sides of the lining steel pipe 1, respectively, which can further avoid stress concentration and thus improve welding quality.
[0031] As a preferred solution of the present invention, the first weld 21 and the second weld 31 are located on the same side of the lining steel pipe 1 .
[0032] Specifically, the first weld 21 and the second weld 31 may also be located on the same side of the lining steel pipe 1, as long as the projection on the side wall of the steel pipe to be spliced is a Z-shaped structure.
[0033] As a preferred solution of the present invention, the length of the lined steel pipe 1 is 100 mm-110 mm.
[0034] Specifically, the length of the lined steel pipe 1 can be determined according to the actual length of the steel pipes to be spliced, and the utility model does not specifically limit the specific length of the lined steel pipe 1.
[0035] As a preferred solution of the present invention, the first weld 21 is arranged along the length direction of the first steel pipe 2 to be spliced; the second weld 31 is arranged along the length direction of the second steel pipe 3 to be spliced.
[0036] Specifically, the overall length of the first weld 21 is set along the length direction of the first steel pipe 2 to be spliced, but because its projection and the projection of the second weld 31 are spliced in a Z shape, it also has a certain length in the diameter direction of the first steel pipe 2 to be spliced, as shown in FIG. Figure 1 The second weld 31 also has an overall length that is arranged along the length direction of the second steel pipe 3 to be spliced, but also has a certain length in the diameter direction of the second steel pipe 3 to be spliced.
[0037] As a preferred solution of the present invention, the total length of the first weld 21 and the second weld 31 is greater than half of the length of the lining steel pipe 1 .
[0038] Specifically, the starting end and the ending end of the Z-shaped weld projection formed by the projection and splicing of the first weld 21 and the second weld 31 are both greater than half of the length of the lining steel pipe 1, so that the welding fixation is more firm.
[0039] As a preferred solution of the utility model, the sleeve length of the first steel pipe 2 to be spliced at one end of the lining steel pipe 1 is equal to the sleeve length of the second steel pipe 3 to be spliced at the other end of the lining steel pipe 1.
[0040] Specifically, the sleeve length of the first steel pipe 2 to be spliced at one end of the lining steel pipe 1 is equal to the sleeve length of the second steel pipe 3 to be spliced at the other end of the lining steel pipe 1, that is, the length of the sleeve overlapping part of the first steel pipe 2 to be spliced and one end of the lining steel pipe 1 is equal to the length of the sleeve overlapping part of the second steel pipe 3 to be spliced and the other end of the lining steel pipe 1, thereby increasing the symmetry of the structure and making the force on the welding part equal.
[0041] As a preferred solution of the present invention, the width of the butt gap between the butt end of the first steel pipe 2 to be spliced and the butt end of the second steel pipe to be spliced is 20 mm.
[0042] Specifically, the butt gap between the butt end of the first steel pipe 2 to be spliced and the butt end of the second steel pipe to be spliced can be determined according to actual conditions, and the present invention does not make any special limitation on this.
[0043] As a preferred solution of the present invention, the wall thicknesses of the first steel pipe 2 to be spliced, the second steel pipe 3 to be spliced, and the lining steel pipe 1 are all equal.
[0044] Specifically, the wall thicknesses of the first steel pipe 2 to be spliced, the second steel pipe 3 to be spliced, and the lining steel pipe 1 are all equal, so that the welding of the three is more firm.
[0045] As a preferred solution of the present invention, the groove angle of the welding groove of the first weld 21 is 45°; the groove angle of the welding groove of the second weld 31 is 45°.
[0046] Specifically, the groove angle of the weld can be determined according to actual needs, and the present invention does not make any special limitation on this.
[0047] In order to better illustrate the support steel pipe splicing node structure provided by the utility model, a specific application example is as follows Figure 3 shown.
[0048] When constructing a steel structure support frame, the frame 4 can be made in the factory according to the size of the drawing, and the splicing position of the splicing joint 5 can be reserved. Then, the steel pipes to be spliced can be spliced in the factory or on site according to the requirements of the drawing using the support steel pipe splicing node structure provided by the utility model, and fixed by welding through the first weld 21 and the second weld 31 until the steel pipes to be spliced meet the preset length. The spliced steel pipes are installed in the frame 4 in a central cross manner, and fixed by welding through the splicing joint 5 in the center. The ends of the spliced steel pipes are fixed to the frame 4 by welding through the free joint 6, thereby obtaining a complete frame unit. Among them, the frame 4 can also be spliced by the node structure in the utility model when welding.
[0049] It can be seen from the above specific implementation methods that the supporting steel pipe splicing node structure provided by the utility model improves the splicing accuracy between the steel pipes to be spliced by lining the steel pipe and correspondingly arranging the first weld and the second weld on the first steel pipe to be spliced and the second steel pipe to be spliced. The amount of on-site welding is small, and it is easy to meet the welding quality requirements; the projections of the first weld and the second weld on the side walls of the first steel pipe to be spliced and the second steel pipe to be spliced are in a Z-shaped structural design, which avoids the generation of welding stress concentration and makes the structure safer and more complete; the utility model has the advantages of simple operation, fast construction speed, high installation accuracy, and reduced project cost.
