[0022] In order for those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below.

[0023] The embodiment of the present application discloses an ideal hinged suspension steel structure node structure based on a 3D printing steel structure technology, as shown in Figure 2As shown, the node structure comprises a connecting node, the connecting node comprises a first connecting piece 1, a second connecting piece 2, the second connecting piece 2 is provided with a ball head 21, the first connecting piece 1 is spliced by a plurality of connecting parts 11, the first connecting piece 1 is provided with a containing cavity, the second connecting piece 2 is hinged with the containing cavity of the first connecting piece 1 through the ball head 21, the splicing part of adjacent connecting parts 11 is provided with a reinforcing piece 12, and the reinforcing piece 12 is fixedly connected with the connecting part 11.

[0024] The containing cavity is a spherical cavity structure, the lower part is provided with an opening, and the first connecting piece 1 is provided with a flared structure which is narrow at the top and wide at the bottom at the opening, and can be clamped and fixed with the ball head 21. The second connecting piece 2 comprises a ball head 21 and a conical seat, the ball head 21 is installed on the conical seat, in the embodiment of the application, the ball head 21 and the conical seat are both 3D printed steel structures and are integrally formed, and are connected with the lower suspended steel pipe column through the conical seat. The first connecting piece 1 and the second connecting piece 2 can realize universal hinge function under the action of the containing cavity and the ball head 21. The adjacent connecting parts 11 are welded and fixed, and the reinforcing piece 12 is welded between the adjacent connecting parts 11, so as to reinforce the connecting part 11.

[0025] The embodiment of the application realizes universal hinge connection of the first connecting piece 1 and the second connecting piece 2 by arranging the ball head 21 and the containing cavity, and realizes reinforcement and fixation of the connecting part 11 by cooperating with the reinforcing piece 12, so as to improve the structural stress performance of the first connecting piece 1.

[0026] Optionally, as shown in Figure 2 The connecting part 11 is in an arc structure.

[0027] In particular, as shown in Figure 3 The first connecting piece 1 is spliced into a cylindrical structure by a plurality of connecting parts 11.

[0028] The connecting part 11 is two, the radian of the arc structure is 180 degrees, and the connecting part 11 is a continuous structure at the opening. The connecting part 11 of the embodiment of the application can also be selected to be three or more than three according to needs. During installation, the connecting part 11 is spliced around the ball head 21 and is welded and fixed.

[0029] The traditional universal hinge structure sets the first connecting piece 1 as an integral structure, and sets a plurality of opening formed disconnected structures at the opening of the first connecting piece 1, so that the opening of the first connecting piece 1 has certain variability, and the ball head 21 is convenient to insert into the accommodating cavity, but such structure itself also causes the stress performance of the first connecting piece 1 to be reduced, and when the external force is too large, the ball head 21 is also caused to be separated from the accommodating cavity. The embodiment of the present application sets a plurality of connecting parts 11, and the ball head 21 is installed in the accommodating cavity by the spliced welding of the connecting parts 11, so that the connecting parts 11 can be set as a continuous structure at the opening, the stress performance of the first connecting piece 1 is improved, and the possibility of the ball head 21 being separated from the accommodating cavity is reduced.

[0030] Particularly, as shown in Figure 3 The inner wall of the reinforcing part 12 is arc-shaped, and the reinforcing part 12 is welded and fixed with the at least two adjacent connecting parts 11 through the inner wall.

[0031] The inner wall of the reinforcing part 12 is spliced and welded with the two adjacent connecting parts 11, and is welded to realize fixation. The reinforcing part 12 of the embodiment of the present application is two.

[0032] The embodiment of the present application fixes the welding part of the connecting part 11 by setting the reinforcing part 12, and reduces the separation of the adjacent connecting parts 11.

[0033] Particularly, as shown in Figure 3 The inner wall of the reinforcing part 12 is not less than 90 degrees.

[0034] The inner wall of the reinforcing part 12 is not less than 90 degrees.

[0035] The embodiment of the present application sets that the inner wall of the reinforcing part 12 is not less than 90 degrees, and is preferably 120-150 degrees. When the first connecting piece 1 is subjected to a force in a direction of separating the adjacent connecting parts 11, the inner wall of the reinforcing part 12 can realize the transmission of the force and the deflection of the direction, so as to reduce the risk of separation of the adjacent connecting parts 11.

[0036] Optionally, as shown in Figure 3 The accommodating cavity of the first connecting piece 1 is also provided with a plurality of first sliding layers 13, and the ball head 21 abuts against the inner wall of the accommodating cavity through the first sliding layer 13.

[0037] The first sliding layer 13 is two layers.

[0038] Particularly, the first sliding layer 13 is a polytetrafluoroethylene sliding layer.

[0039] The embodiment of the present application sets the polytetrafluoroethylene sliding layer, reduces the friction between the ball head 21 and the accommodating cavity, and improves the durability.

[0040] The node structure of the embodiment of the present application further comprises a top fixing member 3, a bottom column 4 and a column foot 5, one end of the top fixing member 3 is fixedly connected with the first connecting member 1, one end of the bottom column 4 is fixedly connected with the second connecting member 2, and the other end of the bottom column 4 is anchored with the column foot 5.

[0041] The top fixing member 3 is a frame body, a column body or a top wall structure, which can realize lifting of the first connecting member 1, thereby forming a suspended steel structure.

[0042] In particular, the bottom column 4 further comprises a universal member 41, the universal member 41 comprises a buried member 411 provided at the bottom and a spherical steel arc plate 412, the buried member 411 is anchored with the column foot 5, the bottom column 4 is sleeved outside the spherical steel arc plate 412, a second sliding layer 42 is provided at the inner side of the bottom of the bottom column 4, and the spherical steel arc plate 412 abuts against the second sliding layer 42.

[0043] The second sliding layer 42 and the first sliding layer 13 are of the same material. The spherical steel arc plate 412 is a 3D printed steel structure, and the spherical steel arc plate 412 can be selected as a spherical structure or a partial spherical structure. There is a neck structure between the spherical steel arc plate 412 and the buried member 411. The bottom of the bottom column 4 is sleeved outside the spherical steel arc plate 412, so that the bottom of the bottom column 4 can be adjusted in angle relative to the spherical steel arc plate 412, thereby achieving the effect of universal hinge connection. Meanwhile, the bottom of the bottom column 4 is a through groove structure, and the spherical steel arc plate 412 can slide relative to the bottom of the bottom column 4, so that the bottom column 4 can slide in the vertical direction relative to the spherical steel arc plate 412.

[0044] The connecting part 11 (two half-arc-shaped steel pipes) of the connecting node and the second connecting member 2 (spherical steel structure) with the spherical head part 21 of the embodiment of the present application adopt a 3D printed steel structure technology, which realizes universal rotation. The outer side of the connecting part 11 is attached and welded with a reinforcing member 12 (a reinforcing steel plate), which is used as a multi-line defense line, so that the connecting node is more reliable. The connecting part 11 (two half-arc-shaped steel pipes) and the second connecting member 2 (spherical steel structure) can be quickly installed on site, which also improves the construction efficiency and quality. Meanwhile, the bottom column 4 and the universal member 41 form a lower fulcrum node in the embodiment of the present application. Compared with a traditional short straight steel pipe, the bottom column 4 is improved to a spherical steel plate (an arc-shaped steel plate - a part of a spherical surface), and also adopts a 3D printed steel structure technology. The bottom of the bottom column 4 is sleeved in the universal member 41, thereby forming a hinge structure. Meanwhile, this plug-in structure can also slide in the vertical direction, so that the lower fulcrum node itself has multiple functions of hinge connection and sliding, thereby improving the adjustability of the node structure itself.

[0045] It should be noted that the ideal hinge suspended steel structure node structure based on the 3D printed steel structure technology of the embodiment of the present application has rich application scenarios. For example, in a certain scene of environmental conditions, such as Figure 6As shown, only to meet the needs of the upper node has a suspension steel structure 7, the bottom of the embedded parts, steel beams and other fixed bearing structure 8 can provide the scene can use the scheme of the embodiment of the present application, and the current listed scenarios of the embodiment of the present application are only part of the use cases.
