Description

Technical Field

[0001] This invention relates to the field of steel structure technology for building construction, and in particular to a method for manufacturing a supporting steel column with multiple cantilevered cuboids. Background Technology

[0002] The use of truss support structures in construction is becoming increasingly common. A steel truss is a structure composed of members connected at both ends by bolts, welding, or riveting. The connection between the truss and the main structure is a planar or spatial support structure with triangular units, composed of various non-standard structures. The support members mainly bear the axial tensile force of the truss or the vector compressive force of the main structure, thus making full use of the strength of the material. In applications involving multi-directional spatial support nodes, this can reduce self-weight and increase stiffness.

[0003] The building comprises two towers, a two-story podium, and a feather bridge. Each tower features six cantilevered cubes, each topped with a massive cantilevered truss layer, creating a spacious environment. Because the truss connection nodes and floor beams are welded to box-type support columns, and the irregularly shaped steel columns of the cantilever truss are connected to the main structure at an angle, the secondary trusses and beams require high control over their on-site installation points, posing significant challenges to the fabrication of the box-type support columns. Furthermore, the thick steel plates at the support column node areas (up to 80mm thick) and the complex assembly of the internal reinforcing plates, coupled with the fact that this node is a transfer layer requiring high welding quality, highlight the critical challenges in the manufacturing process, particularly regarding the choice of assembly procedures and welding methods to account for welding shrinkage. Summary of the Invention

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a method for manufacturing a supporting steel column with multiple cantilevered cuboids, which optimizes the assembly and welding process, ensures construction efficiency, and enables the supporting steel column to effectively support the cantilevered cuboids, thus ensuring the safety of the building.

[0005] A method for manufacturing a supporting steel column with multiple cantilevered cuboids according to an embodiment of the present invention includes the following steps:

[0006] S1: Construct the box-shaped main body;

[0007] S2: Two large box-shaped structures. The lower wing of one large box-shaped structure is connected to the side wing on the left side of the box-shaped body, and the lower wing of the other large box-shaped structure is connected to the side wing on the right side of the box-shaped body. The remaining structure of the large box-shaped structure is then welded on the lower wing.

[0008] S3: Two small box-shaped structures, one small box-shaped structure welded to the large box-shaped structure on the left, and the other small box-shaped structure welded to the large box-shaped structure on the right;

[0009] S4: Weld the decorative panel assembly to the top of the box-shaped body;

[0010] S5: Weld the irregular box shape to the bottom of the box body.

[0011] The manufacturing method according to embodiments of the present invention has at least the following beneficial effects:

[0012] This method optimizes the transition nodes between trusses and box columns, reducing on-site installation and welding difficulties. The manufacturing process is optimized by employing root cleaning and unloading welding, solving the problem of excessive welding volume in ultra-thick plates and effectively controlling the cross-sectional dimensions of the main node. The assembly sequence is optimized, reducing the number of times the components are turned over during manufacturing. Double-corner bevel joints are minimized, reducing the risk of Z-direction tearing of the base material. Some partition parts are unloaded using backing welding, and small and irregularly shaped box columns are assembled using separate welding, improving manufacturing efficiency and shortening the construction period.

[0013] According to some embodiments of the present invention, the manufacturing steps of the box-shaped body are as follows:

[0014] Step 1: Using the main web as the base plate, two reinforcing bars are set at intervals in the left and right directions of the main web, and thickened partitions are set at both ends of the reinforcing bars.

[0015] Step 2: Install an intermediate plate on the two reinforcing bars, and install multiple transverse inner partitions at intervals along the front-back direction on the intermediate plate.

[0024] According to some embodiments of the present invention, in step S4, the small box is assembled and then welded to the large box; in step S5, the irregular box is assembled and then welded to the bottom of the box body.

[0025] According to some embodiments of the present invention, the decorative panel assembly includes a first vertical support plate, a second vertical support plate, a third vertical support plate, a fourth vertical support plate, and a decorative panel body.

[0049] In some embodiments of the present invention, reference is made to... Figure 3 , Figure 4 As shown, the manufacturing steps of the box-shaped body 100 are as follows:

[0050] Step 1: Using the main web plate 110 as the base plate, two stiffeners are set at intervals in the left and right directions of the main web plate 110, and thickened partition plates 130 are set at both ends of the stiffeners; specifically, the stiffeners are welded using the withdrawal method, and the stiffeners and the main web plate 110 are welded with pads; the main web plate 110 and the thickened partition plates 130 are beveled with a clean root, and the weld is a first-class full penetration weld.

[0051] Step 2: Install an intermediate plate 140 on the two reinforcing bars. Install multiple transverse inner partitions 150 at intervals along the front-to-back direction on the intermediate plate 140. Adjacent transverse inner partitions 150 and the transverse inner partitions 150 are connected by longitudinal inner partitions 160. For details, refer to... Figure 4 As shown, four transverse inner partitions 150 are placed above the intermediate plate 140. The four transverse inner partitions 150 are spaced apart along the length of the main web plate 110. A longitudinal inner partition 160 is provided between two adjacent transverse inner partitions 150. A longitudinal inner partition 160 is also provided between adjacent transverse inner partitions 150 and thickened partitions 130. The longitudinal inner partitions 160 and thickened partitions 130 are welded by backing weld, and the longitudinal inner partitions 160 and transverse inner partitions 150 are welded by root cleaning weld.

[0052] Furthermore, the thickness of the thickened partition 130 is 80 mm, and the thickness of the remaining transverse inner partition 150 and longitudinal inner partition 160 is less than 80 mm.

During installation, the secondary web plate 220, the transverse partition 230, and the longitudinal partition 240 are assembled sequentially, followed by the upper wing plate 270. Then, the dividing plate 250 is installed in a retractable manner, and finally, the sealing plate 260 is installed. Specifically, refer to... Figure 3 , Figure 5As shown, the two large box-shaped structures 200 are basically identical, therefore their connection method with the box-shaped body 100 is also the same. The two large box-shaped structures 200 are respectively connected to the left and right sides of the box-shaped body 100. The lower wing plate 210 of the large box-shaped structure 200 is preferentially welded to the wing plate of the box-shaped body 100, and then a secondary web plate 220 is welded onto the lower wing plate 210. Each large box-shaped structure 200 includes two secondary web plates 220, which are respectively located on both sides of the width direction of the lower wing plate 210; then a transverse partition 230 and a longitudinal partition 240 are welded, with the transverse partition 230 being installed preferentially.

[0056] Furthermore, the transverse partition 230 is rectangular with four edges. Except for the top edge, which is not welded, the other three edges of the transverse partition 230 are welded to the secondary web 220, the lower flange 210, and the lateral flange 170, respectively, all using a backing weld method. The longitudinal partition 240 is triangular, consisting of three edges, which are welded to the transverse partition 230, the lateral flange 170, and the secondary web 220, also using a backing weld method.

[0057] In some embodiments of the present invention, the lower flange 210 and the side flange 170 are connected by a bevel welding method, and the upper flange 270 and the side flange 170 are connected by a bevel welding method; the secondary web 220 and the lower flange 210 are connected by a backing tear-resistant bevel welding method, and the secondary web 220 and the side flange 170 are connected by a backing bevel welding method.

The sealing plate 260 is rectangular, with its left and right edges welded to two secondary web plates 220 respectively, its top edge welded to the upper flange 270, and its bottom edge welded to the lower flange 210. The partition plate 250 and the sealing plate 260 have essentially the same shape and size.

[0059] In some embodiments of the present invention, in step S4, the small box 300 is assembled and then welded to the large box 200; in step S5, the irregularly shaped box 400 is assembled and then welded to the bottom of the box body 100. Specifically, refer to... Figure 1 , Figure 2 As shown, the small box type 300 and the irregular box type 400 have different shapes, but the shapes and structures of the two small box types 300 are basically the same. The irregular box type 400 and the small box type 300 are assembled and welded as a whole, and then the irregular box type 400 is welded to the bottom of the box body 100. The two small box types 300 are respectively welded to the two large box types 200.

[0060] In some embodiments of the present invention, reference is made to... Figure 1 , Figure 3 As shown, the decorative panel assembly 500 includes a first vertical support plate 510, a second vertical support plate 520, a third vertical support plate 530, a fourth vertical support plate 540, and a decorative panel body 550. The lower edge of the first vertical support plate 510 is welded to the bent web plate 190 by means of backing weld. The lower edge of the second vertical support plate 520 is welded to the upper flange 270 of the left large box-shaped plate 200 by means of backing weld. The lower edge of the third vertical support plate 530 is welded to the upper flange 270 of the right large box-shaped plate 200 by means of backing weld. The two ends of the lower edge of the fourth vertical support plate 540 are respectively... The upper wing plate 270 of the left large box 200 and the upper wing plate 270 of the right large box 200 are welded to the cover plate 180. The lower edge of the vertical support plate 4 540 is welded to the cover plate 180. The vertical support plate 1 510, vertical support plate 2 520, vertical support plate 3 530 and vertical support plate 4 540 are arranged to form an irregular groove that is consistent with the shape of the decorative panel body 550. The decorative panel body 550 is covered on the irregular groove. The edges of the decorative panel body 550 are welded to the vertical support plate 1 510, vertical support plate 2 520, vertical support plate 3 530 and vertical support plate 4 540 respectively.

[0061] It is important to understand that all welds must undergo flaw detection and component integrity acceptance after welding is completed to meet acceptance requirements.

[0062] According to the manufacturing method of this invention, the truss and box column conversion nodes are centrally optimized, reducing the difficulty of on-site installation and welding; the manufacturing process of the components is optimized, and the root cleaning and unloading welding are adopted, which solves the problem of excessive welding volume of ultra-thick plates and effectively controls the cross-sectional dimensions of the node body; the assembly sequence is optimized, reducing the number of times the components are turned over during the manufacturing process; the double-corner joint bevel form is minimized, reducing the risk of Z-direction tearing of the base material; some partition 250 parts are unloaded using backing welding, and small box type 300 and irregular box type 400 are assembled by separate welding, which improves manufacturing efficiency and shortens the construction period.

[0063] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
