[0042] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0043] like Figures 1-15 As shown, this invention discloses an irregular column corbel joint, including an irregular column 1, an upper chord node plate 2, a lower chord node plate 3, a horizontally arranged first corbel 4, and an inclined second corbel 5. The irregular column 1 is divided into three sections from top to bottom: an upper chord segment 6, a middle segment 7, and a lower chord segment 8, and has multiple internal partitions 9. The upper chord node plate 2 is fixedly installed inside the upper chord segment 6, and the lower chord node plate 3 is fixedly installed inside the lower chord segment 8. Both sides of the upper chord node plate 2 and the lower chord node plate 3 extend to the outside of the irregular column 1, and are each connected to the first corbel 4 and the second corbel 5. Both the first corbel 4 and the second corbel 5 are H-shaped corbels, and multiple stiffening plates are fixedly installed between the flanges of the first corbel 4 to enhance the structural strength. Each second bracket 5 is positioned between the first brackets 4. That is, at the upper chord section 6 of the irregular column 1, the second bracket 5 is inserted diagonally below the first bracket 4, while at the lower chord section 8 of the irregular column 1, the second bracket 5 is inserted diagonally above the first bracket 4.

[0044] The irregular column 1 mainly includes components such as a round tube 10, a tapered tube 11, an arc-shaped tube segment 12, and a triangular sealing plate 13. Among them, the round tube 10 includes an inclined circular tube segment 15 and a vertically arranged vertical circular tube segment 16. The inclined circular tube segment 15 is connected below the vertical circular tube segment 16, and the inclined circular tube segment 15 and the vertical circular tube segment 16 are respectively slotted and inserted into the upper chord node plate 2. That is, the upper chord segment 6, the middle segment 7, and the lower chord segment 8 of the irregular column 1 are all partially composed of the inclined circular tube segment 15, and there is a certain angle between the inclined circular tube segment 15 and the vertical circular tube segment 16.

[0045] The arc-shaped tube segment 12 is vertically arranged on the side of the circular tube 10 segment, especially the oblique circular tube segment 15. The tapered tube 11 is coaxially arranged with the arc-shaped tube segment 12 and connected below the arc-shaped tube segment 12. Two triangular sealing plates 13 are symmetrically arranged, parallel and spaced apart, with their edges connecting the two sides of the arc-shaped tube segment 12 and the outer wall of the circular tube 10, respectively. The upper part of the arc-shaped tube segment 12 connects to the outer wall of the circular tube 10, and the lower part connects to the tapered tube 11, thus forming a closed cavity between the arc-shaped tube segment 12 and the outer wall of the circular tube 10. The inner partition plate 9 is arranged inside the circular tube 10 along the axial direction of the circular tube 10, and is also arranged between the outer wall of the circular tube 10 and the triangular sealing plates 13 and the arc-shaped tube segment 12. When the inner partition 9 is placed inside the circular tube 10, it is in the shape of a circular ring or a fan ring. When the inner partition 9 is placed between the circular tube 10, the triangular sealing plate 13 and the arc-shaped tube segment 12, it is in the shape of a crescent or a semi-crescent, so as to play a good supporting role and improve the structural bearing capacity and stability.

[0046] Both the upper chord node plate 2 and the lower chord node plate 3 are bent. After bending, the included angle between the plates of the upper chord node plate 2 used to insert the first bracket 4 and the second bracket 5 is an obtuse angle, and the same applies to the lower chord node plate 3. The lower chord node plate 3 is bent along two parallel bending lines, one of which is located inside the circular tube 10, and the other is located between the arc-shaped tube 12 and the circular tube 10. The two sides of the lower chord node plate 3 pass through the circular tube 10 and the arc-shaped tube 12 to the outside of the irregular column 1, respectively. The part of the lower chord node plate 3 located between the two bending lines is parallel to the two triangular sealing plates 13.

[0047] Two sets of support plates 14 are vertically fixed to the lower chord node. These two sets of support plates 14 are positioned opposite each other on both sides of the lower chord node plate 3, corresponding to the wing plates of the first corbel 4 connected to the lower chord node plate 3. The support plates 14 are horizontally positioned inside the irregular column 1 and outside the circular tube 10. A portion of the support plate 14 extends out of the irregular column 1 and is fixedly connected to the wing plate of the first corbel 4 facing away from the circular tube 10. The three sides of the aforementioned triangular sealing plate 13 are respectively connected to the outer wall of the circular tube 10, the arc-shaped tube segment 12, and the support plate 14 corresponding to the lower wing plate of the first corbel 4, thus sealing the arc-shaped tube segment 12 and the outer wall of the circular tube 10 in conjunction with the support plates 14. The tapered tube 11 is correspondingly connected below the support plate 14, thereby connecting to the arc-shaped tube segment 12.

[0048] In addition, several third brackets 17 are fixedly connected to the outer side of the irregular column 1. The third brackets 17 are horizontally arranged and their positions and heights correspond to those of the first brackets 4. The third brackets 17 can be H-shaped brackets or box-shaped brackets. They can be directly welded to the outer side of the irregular column 1, or they can be connected to the irregular column 1 through the outer insert plate 18 and the through plate 20.

[0049] When the third bracket 17 is connected to the irregular column 1 via the outer insert plate 18, the outer insert plate 18 is vertically fixed to the outside of the irregular column 1, while an inner stiffening plate 19 is vertically fixed inside the irregular column 1. The inner stiffening plate 19 is fixedly connected to the inner wall of the irregular column 1, and can even extend and be fixed to the upper chord node plate 2 and the lower chord node plate 3. The positions of the inner stiffening plate 19 and the outer insert plate 18 correspond internally and externally, which can enhance the structural bearing capacity and improve the local stress distribution. The third bracket 17 can be slotted to insert the outer insert plate 18 to securely connect the irregular column 1.

[0050] When the third bracket 17 is connected to the irregular column 1 through the through plate 20, the irregular column 1 and the outer wall of the irregular column 1 are perpendicular to each other. One side of the through plate 20 passes through the irregular column 1 and is connected to the upper chord node plate 2 or the lower chord node plate 3, and the other side is connected to the third bracket 17. The third bracket 17 is stably connected to the irregular column 1 by slotting and inserting.

[0051] In this embodiment, four third brackets 17 are provided at the upper chord section 6 of the irregular column 1. Two of the third brackets 17 are H-shaped brackets directly welded to the outside of the round tube 10, and the other two are box-shaped brackets connected by inserting an outer plate 18. Four third brackets 17 are provided at the lower chord section 8 of the irregular column 1. Two of the third brackets 17 are H-shaped brackets directly welded to the outside of the round tube 10, one third bracket 17 is a box-shaped bracket connected to the outside of the round tube 10 by inserting an outer plate 18, and the other third bracket 17 is a box-shaped bracket connected by inserting a through plate 20.

[0052] Based on this node, the present invention also discloses a method for fabricating a corbel node for an irregularly shaped column 1, which mainly includes the following steps:

[0053] S1. Fabrication of the first, second, and third precast components. The fabrication of the first, second, and third precast components can be performed sequentially or simultaneously. Specifically, the upper chord section 6 of the irregular column 1 and the corresponding inner partition 9 are welded onto the upper chord node plate 2. Then, the corresponding first bracket 4 and second bracket 5 are welded onto both sides of the upper chord node plate 2 to fabricate the first precast component. The middle section 7 of the irregular column 1 and the corresponding inner partition 9 are assembled and welded to fabricate the second precast component. The lower chord section 8 of the irregular column 1 and the corresponding inner partition 9 are welded onto the lower chord node plate 3. Then, the corresponding first bracket 4 and second bracket 5 are welded onto both sides of the lower chord node plate 3 to fabricate the third precast component. All three precast components can be pre-assembled and welded in the factory for on-site construction.

[0054] S2. The upper chord section 6, the middle section 7 and the lower chord section 8 are welded on site to form an irregular column 1 to connect the first precast part, the second precast part and the third precast part. Then, the hand hole sealing plate 21 is welded to seal the pre-set hand hole on the irregular column 1, and the above-mentioned irregular column 1 corbel node can be made.

[0055] Due to the special structure of the irregular column 1, which requires segmented assembly and welding, and the fact that when adding the third bracket 17, some of the third brackets 17 need to be installed through the outer insert plate 18 and the through plate 20, the first prefabricated component, the second prefabricated component, and the third prefabricated component are mainly manufactured in the following order:

[0056] S11. Based on the positional relationships between the upper chord segment 6, the middle segment 7, and the lower chord segment 8; the positional relationships between the oblique circular tube segment 15 and the vertical circular tube segment 16; the positional relationships between the support plate 14 and the irregular column 1; and the positional relationships between the through plate 20 and the irregular column 1, the circular tube 10 is divided into multiple segments, and the triangular sealing plate 13 and the arc-shaped tube segment 12 are divided into multiple pieces. At the same time, slots are made on the circular tube 10 corresponding to the upper chord node plate 2 and the lower chord node plate 3 for insertion, and the arc-shaped tube segment 12 is pre-cut according to the position and size of the hand hole.

[0057] S12. Assemble and weld the corresponding circular tubes 10, and simultaneously install and weld the inner partition plate 9 inside the circular tube 10 using the retraction method. When manufacturing the first and third precast components, it is also necessary to pre-draw assembly position lines corresponding to components such as the inner stiffening plate 19, support plate 14, and through plate 20 on the upper chord node plate 2 and lower chord node plate 3. During the assembly and welding of the circular tubes 10, the inner stiffening plate 19 is installed and welded inside the circular tube 10 according to the assembly position lines.

[0058] For example, when manufacturing the first precast component, the corresponding section of the circular tube 10 and the inner stiffening plate 19 need to be welded onto the upper chord node plate 2 first, and the inner partition plate 9 inside the section of the circular tube 10 needs to be removed and unwelded at the same time. When welding the inner partition plate 9, the inner partition plate 9 can be divided into four groups, and the first group of inner partition plates 9a, the second group of inner partition plates 9b, the third group of inner partition plates 9c and the fourth group of inner partition plates 9d are welded from the inside of the circular tube 10 to both ends in sequence.

[0059] S13. Weld the support plate 14 and the through plate 20, and assemble and weld the divided triangular sealing plate 13 and the arc-shaped tube segment 12. At the same time, weld the inner partition plate 9 on the outer wall of the round tube 10 and between the triangular sealing plate 13 and the arc-shaped tube segment 12. In this embodiment, the welding of the support plate 14 only needs to be carried out in the fabrication of the third prefabricated part.

[0060] S14. The first bracket 4 and the second bracket 5 are welded onto the upper chord node plate 2 and the lower chord node plate 3.

[0061] S15. Weld an outer insert plate 18 to the outside of the round tube 10, and weld a third bracket 17 to the outer insert plate 18 and the through plate 20 respectively.

[0062] S16. Welding the tapered tube 11. In this embodiment, the welding of the tapered tube 11 only needs to be carried out during the fabrication of the third preform.

[0063] Furthermore, step S11 above also includes pre-bending the upper chord node plate 2 and the lower chord node plate 3, and checking the bending angle and dimensions.

[0064] When manufacturing the first prefabricated component, step S13 further includes: drawing an assembly pattern 22 on a horizontal platform based on the positional relationship between the vertical circular pipe segment 16 and the upper chord node plate 2, and marking four positioning lines 23 along the axial direction on the outer wall of the vertical circular pipe segment 16. These positioning lines 23 correspond to the four circumferential division points of the vertical circular pipe segment 16, with one of the positioning lines 23 located at the longitudinal weld seam during the rolling of the vertical circular pipe segment 16. The assembly pattern 22 includes at least the outline of the outer wall of the vertical circular pipe segment 16, the outline of the upper chord node plate 2, and projection points 24 corresponding to the four positioning lines 23. Then, the vertical circular pipe segment 16 is placed vertically and the upper chord node plate 2 is inserted. The projections of the vertical circular pipe segment 16 and the upper chord node plate 2 are adjusted using a plumb line 25 to ensure they coincide with the assembly pattern 22. Finally, the vertical circular pipe segment 16 and the upper chord node plate 2 are welded together to ensure precise assembly and welding of the vertical circular pipe segment 16.

[0065] When manufacturing the second precast component, steps S14-S16 are not required. However, when manufacturing the third precast component, step S13 further includes: drawing an assembly pattern 22 on a horizontal platform based on the positional relationship between the inclined circular pipe segment 15 and the lower chord node plate 3; and marking four positioning lines 23 along the axial direction on the corresponding section of the inclined circular pipe segment 15. These positioning lines 23 correspond to the four circumferential division points of the inclined circular pipe segment 15, with one of the positioning lines 23 located at the longitudinal weld seam during the rolling of the inclined circular pipe segment 15. The assembly pattern 22 includes at least the outline of the lower chord node plate 3, the bending line position line, and projection points 24 corresponding to the four positioning lines 23. After the assembly pattern 22 is drawn, a jig 26 is erected, and the lower chord node plate 3 is placed on the jig 26 with one side horizontal. The projection of the lower chord node plate 3 is adjusted using a plumb line 25 to ensure it corresponds to the assembly pattern 22. After confirmation, the lower chord node plate 3 is fixed to the jig 26. Next, insert the inclined circular pipe section 15 onto the lower chord node plate 3, and adjust it by using the plumb line 25 to ensure that the projection of the inclined circular pipe section 15 coincides with the assembly pattern 22. Control the relative distance between the inclined circular pipe section 15 and the upper horizontal plane of the lower chord node plate 3 to ensure that the assembly and welding between the inclined circular pipe section 15 and the lower chord node plate 3 are accurate and in place.

[0066] In summary, this node has a unique structure. The irregular column 1 of the node has high bonding strength and stable and reliable connection with the first bracket 4, the second bracket 5, and the third bracket 17. The entire node has a reasonable structure, clear force transmission, and good seismic performance and load-bearing capacity. When manufacturing the node, it can be divided into three prefabricated parts: the first prefabricated component, the second prefabricated component, and the third prefabricated component. These three parts can be prefabricated in the factory and then welded on site. The assembly sequence of the node is reasonable and efficient, and the on-site installation is also relatively simple and convenient.
