[0028] The following further describes the present utility model in conjunction with the accompanying drawings and specific embodiments.

[0029] As Figure 1-3 shown, the present utility model discloses a steel pipe column corbel node, including a steel pipe column 1, a gusset plate 2, two first corbels 3 and two second corbels 4. The gusset plate 2 is fixedly arranged inside the steel pipe column 1 and penetrates through the steel pipe column 1 on both sides. The two first corbels 3 are horizontally arranged on both sides of the steel pipe column 1 and are respectively fixedly connected to both sides of the gusset plate 2 and the outer walls of both sides of the steel pipe column 1. The two second corbels 4 are obliquely arranged on both sides of the steel pipe column 1 and are respectively arranged directly below the two first corbels 3 in one-to-one correspondence, and the two second corbels 4 are respectively fixedly connected to both sides of the gusset plate 2.

[0030] Specifically, the steel pipe column 1 is made of a circular steel pipe. The steel pipe column 1 includes at least two sections of steel pipes arranged in sequence along its own axis and connected up and down. Correspondingly, the gusset plate 2 is inserted into each section of the steel pipe. Using at least two sections of steel pipes connected to form the steel pipe column 1 is more convenient for inserting and assembling the gusset plate 2. Generally, the axes of each section of the steel pipe are arranged parallel to each other. It can also be as Figure 4 shown, set the included angle between the axis of the uppermost steel pipe and its adjacent steel pipe as an obtuse angle, that is, the column end can be set with an angle.

[0031] Inside the steel pipe column 1, there are multiple inner partition plates 5 which are arranged oppositely in a fan-shaped ring on both side surfaces of the gusset plate 2 and are spaced along the axial direction of the steel pipe column 1 to improve the structural strength and rigidity. The inner partition plates 5 are fully penetrated and welded with the steel pipe column 1 and the gusset plate 2 in the form of backing welding to ensure the welding quality and prevent welding deformation.

[0032] The gusset plate 2 is bent, and the bending line 6 is inside the steel pipe column 1 and approaches the center of the steel pipe column 1, that is, there is a certain angle between the two side surfaces of the gusset plate 2.

[0033] The first corbel 3 and / or the second corbel 4 strengthen the connection with the gusset plate 2 and the steel pipe column 1 by means of grooving and inserting into the gusset plate 2 and / or partially consisting of the gusset plate 2. In this embodiment, the first corbel 3 and the second corbel 4 adopt H-shaped corbels. First stiffening plates 7 can be added between the flange plates of the first corbel 3 and the gusset plate 2 and between the flange plates of the second corbel 4 to enhance the bearing capacity. When there is a first stiffening plate 7, the first stiffening plate 7 is fully penetrated (root clearing) and welded to the gusset plate and the flange plates of the first corbel 3 and the second corbel 4.

[0034] As one case, the flange plates of the first corbel 3 and the second corbel 4 are respectively grooved and inserted into the gusset plate 2, and the webs are both composed of the gusset plate 2. As another case, as Figure 5 shown, the flange plate of the first corbel 3 is grooved and inserted into the gusset plate 2, the flange plate of the second corbel 4 is vertically fixed to the side of the gusset plate 2, the webs of the first corbel 3 and the second corbel 4 are both composed of the gusset plate 2, and the upper flange plate of the second corbel 4 extends to the lower flange plate of the first corbel 3 and is connected to the lower flange plate of the first corbel 3.

[0035] In addition to the first corbel 3 and the second corbel 4, a third corbel 8 can also be provided on the outside of the steel pipe column 1. The third corbel 8 is connected to the steel pipe column 1 through an external insertion plate 9. The external insertion plate 9 is arranged on the outside of the steel pipe column 1 and is vertically connected to the outer wall surface of the steel pipe column 1. A second stiffening plate 10 is added inside the steel pipe column 1. The second stiffening plate 10 is vertically connected to the inner wall surface of the steel pipe column 1 and is located inside and outside corresponding to the external insertion plate 9 to enhance the structural bearing capacity and improve the local stress distribution. The third corbel 8 is horizontally arranged. The third corbel 8 is grooved and inserted into the external insertion plate 9 or partially consists of the external insertion plate 9, so as to realize the mutual connection with the steel pipe column 1.

[0036] A fourth corbel 11 can also be provided on the outside of the steel pipe column 1. The fourth corbel 11 is connected to the steel pipe column 1 through a through plate 12. The through plate 12 vertically penetrates the steel pipe column 1 and is fixedly connected to the steel pipe column 1 and the gusset plate 2. The fourth corbel 11 is horizontally arranged and is grooved and inserted into the through plate 12 or partially consists of the through plate 12.

[0037] The above-mentioned third bracket 8 and fourth bracket 9 can adopt box-shaped brackets, H-shaped brackets, special-shaped brackets, etc. When adopting a box-shaped bracket, it is preferably assembled by slotting and inserting an external insertion plate 9 and a through plate 12, and a third stiffening plate (not shown) can be provided between the inner wall surface and the external insertion plate 9. When adopting an H-shaped bracket, it is preferably to use the external insertion plate 9 and the through plate 12 as components of the flange and / or web to improve the connection strength.

[0038] Taking the third node structure as an example, there are three third brackets 8 in this structure, and two of them adopt box-shaped brackets and slot and insert the external insertion plate 9, and one uses the external insertion plate 9 as the web. Taking the fourth node structure as an example, as Figure 6-8 shown, in this structure, the through plate 12 includes a first through plate 13, a second through plate 14, a third through plate 15 arranged horizontally and a fourth through plate 16 arranged vertically. Among them, the positions of the first through plate 13 and the second through plate 14 respectively correspond to the upper and lower flange positions of the first bracket 3, and both the third through plate 15 and the fourth through plate 16 are located between the first through plate 13 and the second through plate 14. A plurality of fourth stiffening plates 18 are arranged in the middle and on both sides of the first through plate 13 and the second through plate 14, and the fourth stiffening plates 18 are arranged at intervals along the radial direction of the steel pipe column 1.

[0039] There are three corresponding fourth brackets 11, one of which is composed of a combination of a T-shaped plate 17 and the first through plate 13 or a combination of a T-shaped plate 17 and the second through plate 14, one is slotted and inserted into the third through plate 15, and one web is composed of the fourth through plate 16 and part of the flange is composed of the second through plate 14.
