Embodiment 1

[0048] The embodiment of the present application discloses a bamboo-jointed steel column. refer to figure 1 The bamboo steel column includes a plurality of coaxially spliced ​​round pipe units 1 and a first connecting plate 2 fixed at the joint of two adjacent round pipe units 1 . During manufacture, the first connecting plate 2 and the round pipe unit 1 are pre-welded and fixed, and then fully welded to reduce the possibility of cracks at the joints of two adjacent round pipe units 1 .

[0049] refer to figure 1 with figure 2 , The two ends of the outer wall of the round pipe unit 1 are provided with chamfers 11 along the circumferential direction. According to needs, the chamfer 11 can also be located at the ends of the inner wall and the outer wall of the round pipe unit 1 , so that the cross section of the end of the round pipe unit 1 is trapezoidal.

[0050] The first connecting plate 2 is a circular steel plate, and the two sides of the first connecting plate 2 are ...

Embodiment 2

[0061] The embodiment of the present application discloses a bamboo-jointed steel column. refer to Figure 4 with Figure 5 , the difference from Embodiment 1 is that the first connecting plate 2 is replaced by the second connecting plate 4, and the structure difference between the second connecting plate 4 and the first connecting plate 2 is; A slot 42 is opened on the side wall, and the bottom of the slot 42 is arc-shaped, which reduces the possibility of cracks forming along the slot 42 when the second connecting plate 4 is subjected to an external force. The slot 42 divides the end of the second connecting plate 4 into two symmetrically arranged flanges 41 , and the flanges 41 are provided with a plurality of fan-shaped openings along the circumferential direction. The flanges 41 on each side are bent away from each other to form a truncated cone-shaped shell. After bending, the fan-shaped opening is reduced, and the frequency of examination of two adjacent patents will ...

Embodiment 3

[0065] The embodiment of the present application discloses an auxiliary manufacturing device for a bamboo-jointed steel column. refer to Figure 8 with Figure 9 The auxiliary production device includes a linear guide rail 5 and two pressing mechanisms 6 mounted on the guide rail 5 that can approach and move away from each other. A plurality of support mechanisms 7 are installed between the two pressing mechanisms 6 on the guide rail 5 . Place the round tube unit 1 to be welded on the supporting mechanism 7 for support, place the second connecting plate 4 between two adjacent round tube units 1, and then press and tighten the plurality of round tube units 1 using the pressing mechanism 6 , and then perform pre-welding and full-welding operations.

[0066] refer to Figure 8 , the pressing mechanism 6 includes a support 61 that slides relative to the guide rail 5, and a drive rod 62 is threaded on the support 61 along the length direction of the guide rail 5, and a top plate...

Abstract

The invention relates to a bamboo joint steel column, a manufacturing process and an auxiliary manufacturing device, and relates to the technical field of steel structures. The bamboo joint steel column comprises at least two coaxially-arranged circular pipe units, a connecting plate is fixed to a joint between every two adjacent circular pipe units, a positioning groove is formed in each connecting plate, and the two positioning grooves are coaxially formed. Chamfers are arranged on the sides, away from the central axis, of the end faces of the circular pipe units in the circumferential direction, brazing layers are fixedly arranged on the positioning grooves, and the contact positions between the connecting plates and every two adjacent circular pipe units are fixed in a full-length welding manner in the circumferential direction. The manufacturing process includes the steps of manufacturing the circular pipe units, manufacturing the connecting plates, conducting pre-welding and conducting full-welding. The auxiliary manufacturing device comprises a guide rail and two jacking and pressing mechanisms installed on the guide rail, each jacking and pressing mechanism comprises a support connected to the guide rail in a sliding manner, a top plate is installed on each support, a positioning part is arranged on each top plate, and a limiting part used for fixing the position of each support is arranged between each support and the guide rail. The bamboo joint steel column, the manufacturing process and the auxiliary manufacturing device have the beneficial effects of improvingthe weld joint quality of the bamboo joint steel column and reducing the crack possibility.
