The special-shaped column 1 is divided into three sections: an upper chord section 6, an intermediate section 7 and a lower chord section 8 from top to bottom, and a plurality of inner partition plates 9 are arranged inside. The upper chord gusset plate 2 is fixedly arranged in the upper chord section 6, the lower chord gusset plate 3 is fixedly arranged in the lower chord section 8, both sides of the upper chord gusset plate 2 and both sides of the lower chord gusset plate 3 penetrate to the outside of the special-shaped column 1, and the first corbel 4 and the second corbel 5 are inserted. Both the first corbel 4 and the second corbel 5 adopt H-shaped corbels, and a plurality of stiffening plates are fixedly arranged between the flange plates of the first corbel 4 to strengthen the structural strength. Each second corbel 5 is arranged between the first corbels 4, that is, at the upper chord section 6 of the special-shaped column 1, the second corbel 5 is obliquely inserted below the first corbel 4, and at the lower chord section 8 of the special-shaped column 1, the second corbel 5 is obliquely inserted above the first corbel 4.

[0028] The special-shaped column 1 mainly includes components such as a circular tube 10, a conical tube 11, an arc-shaped tube sheet 12, and a triangular sealing plate 13. Among them, the circular tube 10 includes an inclined circular tube section 15 and a vertical circular tube section 16. The inclined circular tube section 15 is connected below the vertical circular tube section 16, and the inclined circular tube section 15 and the vertical circular tube section 16 are respectively slotted and inserted with the upper chord joint plate 2. That is to say, part of the upper chord section 6, the middle section 7, and the lower chord section 8 of the special-shaped column 1 are composed of the inclined circular tube section 15, and there is a certain angle between the inclined circular tube section 15 and the vertical circular tube section 16.

[0029] The arc-shaped tube sheet 12 is vertically arranged on the side of the circular tube 10 section, especially the inclined circular tube section 15. The conical tube 11 is coaxially arranged with the arc-shaped tube sheet 12 and is connected below the arc-shaped tube sheet 12. There are two symmetrically arranged triangular sealing plates 13. The two triangular sealing plates 13 are parallel and spaced apart, and their edges are respectively connected to both sides of the arc-shaped tube sheet 12 and the outer wall of the circular tube 10. The upper part of the arc-shaped tube sheet 12 is connected to the outer wall of the circular tube 10, and the lower part is connected to the conical tube 11, thereby forming a closed cavity between the arc-shaped tube sheet 12 and the outer wall of the circular tube 10. The inner partition 9 is arranged inside the circular tube 10 and is arranged along the axial direction of the circular tube 10, and is also arranged between the outer wall of the circular tube 10, the triangular sealing plate 13, and the arc-shaped tube sheet 12.

[0030] Both the above-mentioned upper chord joint plate 2 and the lower chord joint plate 3 are bent. After bending, the included angle between the plate surfaces of the upper chord joint plate 2 for inserting the first bracket 4 and the second bracket 5 is an obtuse angle, and the same is true for the lower chord joint plate 3. The lower chord joint plate 3 is bent along two parallel bending lines. One bending line is located inside the circular tube 10, and the other is located between the arc-shaped tube sheet 12 and the circular tube 10. Both sides of the lower chord joint plate 3 pass through the circular tube 10 and the arc-shaped tube sheet 12 to the outside of the special-shaped column 1, and the part of the lower chord joint plate 3 between the two bending lines is parallel to the two triangular sealing plates 13.

[0031] Two groups of support plates 14 are vertically fixed on the lower chord joint. The two groups of support plates 14 are relatively arranged on both sides of the lower chord joint plate 3, and their positions correspond to the wing plates of the first bracket 4 connected to the lower chord joint plate 3. The support plate 14 is horizontally arranged inside the special-shaped column 1 and is located outside the circular tube 10. Part of the support plate 14 penetrates out of the special-shaped column 1 and is fixedly connected to the wing plate of the first bracket 4 facing away from the circular tube 10. The three sides of the above-mentioned triangular sealing plate 13 are respectively connected to the outer wall of the circular tube 10, the arc-shaped tube sheet 12, and the support plate 14 corresponding to the lower wing plate of the first bracket 4, and cooperate with the support plate 14 to hermetically connect the arc-shaped tube sheet 12 and the outer wall of the circular tube 10. The conical tube 11 is correspondingly connected below the support plate 14, and then connected to the arc-shaped tube sheet 12.

[0032] In addition, a number of third corbels 17 are fixedly connected to the outer side of the special-shaped column 1. The third corbels 17 are horizontally arranged, and their position heights correspond to those of the first corbels 4. The third corbels 17 can be selected from one or two of H-shaped corbels and box-shaped corbels, and can be directly welded to the outer side of the special-shaped column 1, or can be connected to the special-shaped column 1 through an external insertion plate 18 and a through plate 20.

[0033] When the third corbel 17 is connected to the special-shaped column 1 through the external insertion plate 18, the external insertion plate 18 is vertically fixed to the outer side of the special-shaped column 1, and an internal stiffening plate 19 is vertically fixed inside the special-shaped column 1. The internal stiffening plate 19 is fixedly connected to the inner wall of the special-shaped column 1 and the internal stiffening plate 19, and can even extend and be fixed to the upper chord joint plate 2 and the lower chord joint plate 3. Moreover, the positions of the internal stiffening plate 19 and the external insertion plate 18 correspond to each other inside and outside, which can enhance the structural bearing capacity and play a role in improving the local stress distribution. The third corbel 17 can be slotted and inserted into the external insertion plate 18 to stably connect to the special-shaped column 1.

[0034] When the third corbel 17 is connected to the special-shaped column 1 through the through plate 20, the special-shaped column 1 is perpendicular to the outer wall of the special-shaped column 1. One side of the through plate 20 penetrates through the special-shaped column 1 and is connected to the upper chord joint plate 2 or the lower chord joint plate 3, and the other side is connected to the third corbel 17. The third corbel 17 is stably connected to the special-shaped column 1 by means of slotted insertion.

[0035] In this embodiment, four third corbels 17 are arranged at the upper chord section 6 of the special-shaped column 1. Two of the third corbels 17 are directly welded to the outer side of the round tube 10 by using H-shaped corbels, and the other two third corbels 17 are box-shaped corbels and are connected by inserting the external insertion plate 18. Four third corbels 17 are arranged at the lower chord section 8 of the special-shaped column 1. Two of the third corbels 17 are directly welded to the outer side of the round tube 10 by using H-shaped corbels, one third corbel 17 is a box-shaped corbel and is connected to the outer side of the round tube 10 by inserting the external insertion plate 18, and another third corbel 17 is a box-shaped corbel and is connected by inserting the through plate 20. A handhole cover plate 21 is also welded on the special-shaped column 1.
