Abstract

This application discloses a rigid column, comprising a first support segment, a connecting segment, and a second support segment arranged in the same direction and connected sequentially. The first support segment is thinner than the second support segment. Both the first and second support segments have mounting seats at their axial ends. The connecting segment has two ends, a small-diameter end and a large-diameter end, respectively matching the dimensions of the first and second support segments, with the small-diameter end and the large-diameter end fixedly connected to two mounting seats. The second support segment includes a curved panel and a folded panel, with the curved panel located at a local position in the circumferential direction of the second support segment, and the folded panel located at the remaining positions in the circumferential direction. This segmented design of the rigid column utilizes the connecting segment to connect the first and second support segments of different thicknesses, improving the welding sequence and optimizing the processing flow, which helps ensure welding deformation and weld quality in each segment.

Description

Technical Field

[0001] This application relates to the field of steel structure technology, and in particular to a rigid column. Background Technology

[0002] With rapid economic development, buildings are becoming taller and larger. Considering structural strength, safety performance and other aspects, the structural form of buildings is shifting from reinforced concrete structures to steel-reinforced concrete structures or steel structures.

[0003] The underground portion of high-rise buildings experiences relatively low stress. Designing the steel columns of such buildings as uniform cross-section columns from bottom to top would be wasteful of materials. Therefore, a cross-shaped to box-shaped member can be used instead of uniform cross-section steel columns to better balance the stress characteristics and material cost requirements of the steel structure. The aforementioned cross-shaped to box-shaped member can be seen as a combination of a cross-shaped column and a box-shaped column. For example, the cross-shaped column and the box-shaped column extend in the same direction and are fixedly connected. The cross-shaped column has a roughly cross-shaped cross-section, while the box-shaped column has a roughly box-shaped cross-section, and the cross-shaped column's cross-section is often significantly smaller than that of the box-shaped column. Furthermore, besides cross-shaped to box-shaped members, common cross-shaped to circular tube column members also have a similar effect, better balancing the stress characteristics and material cost requirements of the steel structure.

[0004] However, the aforementioned cross-shaped to box-shaped and cross-shaped to circular tube column components also have significant drawbacks. For example, in the cross-shaped to box-shaped component, one end of the cross-shaped column needs to be inserted into the box-shaped column for internal welding, so that the four flanges of the cross-shaped column are welded one-to-one to the four wall panels of the box-shaped column. However, the internal welding operation is difficult, the welding process is not visible, and it is difficult to guarantee the quality of the weld. When welding the four flanges and four wall panels, the assembly process of the flanges and wall panels is carried out concurrently with the welding process, and some flanges may not be able to be welded to the corresponding wall panels due to excessive welding errors of other flanges. In addition, when welding the last pair of flanges and wall panels, it is necessary to slot the last wall panel of the box-shaped column to achieve welding. This not only increases the complexity of the process, but also inevitably changes the original structure of the box-shaped column, often requiring the original design unit to re-verify the parameters of the box-shaped column. Furthermore, the box-shaped columns of the cross-shaped to box-shaped component are often exposed on the ground, but the appearance of the box-shaped column has significant limitations and is difficult to adapt to the various requirements of ground construction.

[0044] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

Figure 13 This is a schematic diagram of the structure of the first arched reinforcing plate and the second arched reinforcing plate provided in the embodiments of this application; Figure 14 This is a schematic diagram of the structure of the first support segment provided in an embodiment of this application.

[0046] Please refer to Figure 1 , Figure 2 and Figure 9 This application provides a rigid column, including a first support segment 1, a connecting segment 2, and a second support segment 3; the first support segment 1, the connecting segment 2, and the second support segment 3 are distributed in the same direction and connected in sequence; wherein, the shaft ends of both the first support segment 1 and the second support segment 3 are provided with mounting seats 4, and the two ends of the connecting segment 2 are respectively connected to the mounting seats 4 of the first support segment 1 and the second support segment 3.

[0047] In this embodiment, the first support segment 1 is thinner than the second support segment 3. Correspondingly, the connecting segment 2 gradually widens from one end to the other, forming a small-diameter end and a large-diameter end that match the dimensions of the first support segment 1 and the second support segment 3, respectively. Obviously, the small-diameter end is connected to the mounting base 4 of the first support segment 1, and the large-diameter end is connected to the mounting base 4 of the second support segment 3.

[0048] In this embodiment, the second support segment 3 includes a curved panel 311 and a folded panel 312. The curved panel 311 is located at a partial position in the circumferential direction of the second support segment 3, and the folded panel 312 is located at the remaining position in the circumferential direction of the second support segment 3. It can be seen that the curved panel 311 and the folded panel 312 together form the circumferential surface of the second support segment 3.

[0049] The rigid column segmented design provided in this embodiment features a second support segment 3 with a specific shaped outer peripheral surface. Combining the second support segment 3 with the first support segment 1 and the connecting segment 2 can meet various construction requirements, allowing the rigid column to better perform its positioning and support functions. The connecting segment 2 securely connects the first support segment 1 and the second support segment 3, which have different thicknesses, into a single unit, improving the welding sequence, optimizing the processing flow, and benefiting the welding deformation and weld quality of each segment. Therefore, the rigid column provided in this embodiment not only meets the construction characteristics requirements of different areas of the rigid column but also improves the processing technology and reduces the difficulty of production and assembly.

[0050] The rigid column provided in this application will be further described below with reference to the accompanying drawings and embodiments.

[0051] For reference Figure 1, Figure 2 , Figure 9 , Figure 10 and Figure 14 In some embodiments, the rigid column includes a first support segment 1, a connecting segment 2, and a second support segment 3. Any one of the first support segment 1, the connecting segment 2, and the second support segment 3 includes an inner support and an outer shell. The inner support is disposed within the outer shell; in other words, the outer shell surrounds the inner support.

[0052] In the above embodiment, the first support section 1, the connecting section 2, and the second support section 3 all have an inner support and an outer shell. When using rigid columns for specific construction operations, concrete or other filler materials can be poured between the inner support and the outer shell to further improve the structural strength of the rigid column.

[0053] For reference Figures 7 to 9 Based on the above embodiments, the second support section 3 includes an inner support and an outer shell, the outer shell being formed by a curved panel 311 and a folded panel 312; both the curved panel 311 and the folded panel 312 are provided with cutouts 5, any one of the cutouts 5 is adjacent to the shaft end of the outer shell of the second support section 3, or any one of the cutouts 5 is connected to the shaft end of the outer shell of the second support section 3.

[0054] The outer shell of the second support section 3 is formed by a curved panel 311 and a folded panel 312, thus giving the outer shell of the second support section 3 a cylindrical shape. In the above embodiment, any cut 5 adjacent to the axial end of the outer shell of the second support section 3 means that the cut 5 is separated from the cylindrical opening of the aforementioned outer shell, and any cut 5 connected to the axial end of the outer shell of the second support section 3 means that the cut 5 is connected to the cylindrical opening of the aforementioned outer shell.

[0055] Typically, the outer shell of the second support section 3 is provided with multiple cuts 5. One of the functions of these cuts 5 is to serve as filling ports. Construction workers can fill concrete and other fillers either through the filling ports of the aforementioned outer shell or through the aforementioned cuts 5. The latter helps to fill the concrete with poor fluidity more quickly and evenly between the outer shell and the inner support of the second support section 3, thereby improving filling efficiency and filling quality.

[0056] For reference Figures 4 to 9 Based on the above embodiments, the outer shell of the second support section 3 includes a curved panel 311 and a folded panel 312; the curved panel 311 is specifically an arched plate formed by cutting along the axial direction of the cylinder, and the central angle of the arched plate is not greater than 0°; the folded panel 312 may include a first flat plate 3121, a second flat plate 3122 and a third flat plate 3123, the third flat plate 3123 and the curved panel 311 are distributed opposite to each other, and the first flat plate 3121 and the second flat plate 3122 are distributed opposite to each other.

[0057] The aforementioned shape of the second support segment 3 results in a horseshoe-shaped cross-section for its outer shell. During construction using rigid columns, multiple rigid columns can be arranged in a ring around the construction center. In this process, the curved panel 311 of any rigid column faces outwards, while the folded panel 312 faces inwards. The outward-facing curved panels 311 of all rigid columns give the building's outer perimeter a curved surface characteristic, which improves the building's appearance and reduces the impact of external wind forces on the building with less material. The inward-facing folded panels 312 of all rigid columns facilitate easy and quick positioning and installation of any rigid column using any plane of the folded panel 312.

[0058] For reference Figure 1 and Figure 2 As for the first support segment 1, its cross-section can be set as a centrally symmetrical figure or a regular polygon with an odd number of sides. When using rigid columns for specific construction operations, the first support segment 1 is often buried underground, while the second support segment 3 extends out of the ground. The aforementioned first support segment 1 has a regular shape, which can better serve as the foundation structure to support the building above. The aforementioned second support segment 3 has a horseshoe-shaped cross-section, which has good installation characteristics and appearance performance.

[0059] For reference Figure 1 , Figure 2 and Figure 14 As described above, the first support segment 1, the connecting segment 2, and the second support segment 3 all have an inner support and an outer shell. In some embodiments, the inner support of the first support segment 1 can be configured as a first radial support 11, and the outer shell of the first support segment 1 includes multiple first reinforcing plates 12. The first radial support 11 of the first support segment 1 has multiple first radial edges, all of which are of equal length; all the first radial edges are correspondingly disposed on all the first reinforcing plates 12, and any one of the first radial edges is fixedly connected to the corresponding first reinforcing plate 12, while adjacent first reinforcing plates 12 are separated from each other.

[0060] For reference, 14, in the above embodiment, the first radial bracket 11 can be specifically set as a cross-shaped bracket. Obviously, the cross-shaped bracket has four first radial sides of equal length. These four first radial sides are respectively connected to four first reinforcing plates 12. Any one of the first reinforcing plates 12 is vertically fixed to the corresponding first radial side. These four first reinforcing plates 12 are on the same square outline.

[0061] The shape and structure of the first support segment 1 provided in the above example are for reference. In addition, the first support segment 1 can also be designed as other column structures that meet the requirements of construction operations.

[0062] For reference Figure 1 , Figure 2 , Figure 10 and Figure 11 The cross-section of connecting segment 2 is similar in shape to that of the first support segment 1, and can also be set as a centrally symmetrical figure or a regular polygon with an odd number of sides. For example, the inner support of connecting segment 2 is a second radial support 21, and the outer shell of connecting segment 2 includes a plurality of second reinforcing plates 22. All the second reinforcing plates 22 are provided one-to-one on all the second radial sides, and adjacent second reinforcing plates 22 are separated from each other.

[0063] For reference Figures 10 to 14 In the above embodiments, any one of the first reinforcing plates 12 can be set as a flat plate; any one of the second reinforcing plates 22 can include a first arched reinforcing plate 221 and a second arched reinforcing plate 222; in this embodiment, the first arched reinforcing plate 221 and the second arched reinforcing plate 222 are distributed sequentially along the length direction of the connecting segment 2 and are connected to each other; in this embodiment, the axis of the first arched reinforcing plate 221 is parallel to the length direction of the connecting segment 2, and the axial direction of the second arched reinforcing plate 222 is inclined to the length direction of the connecting segment 2.

[0064] like Figure 2 and Figure 10 As shown, the outer shell of the connecting section 2 includes multiple pairs of first arched reinforcing plates 221 and second arched reinforcing plates 222. The same-side ends of all the first arched reinforcing plates 221 and the same-side ends of all the second arched reinforcing plates 222 can respectively enclose the small-diameter end and the large-diameter end of the connecting section 2.

[0065] For reference Figure 1 , Figure 2 , Figure 3 , Figure 11 and Figure 14 Based on the above embodiments, the outer shell of the second support segment 3 is provided with multiple cuts 5, and any one of the cuts 5 is connected to the shaft end of the outer shell of the second support segment 3; the shaft end of the outer shell of the second support segment 3 is provided with multiple extension plates 32, and all extension plates 32 and all cuts 5 are alternately spaced. In the rigid column provided in this application, the first support segment 1, the connecting segment 2 and the second support segment 3 are distributed in the same direction and connected in sequence. The first support segment 1 includes multiple first reinforcing plates 12 disposed on the outer periphery, the connecting segment 2 includes multiple second reinforcing plates 22 disposed on the outer periphery, and the second support segment 3 includes multiple extension plates 32 disposed on the outer periphery. The number of all extension plates 32, the number of all second reinforcing plates 22 and the number of all first reinforcing plates 12 are all equal. All first reinforcing plates 12 and all second reinforcing plates 22 correspond one-to-one and are connected by corresponding mounting seats 4. All second reinforcing plates 22 and all extension plates 32 correspond one-to-one and are connected to each other by corresponding mounting seats 4.

[0066] In the above embodiments, the first support segment 1, the connecting segment 2, and the second support segment 3 are easy to install and can safely and effectively transfer stress, thereby improving the structural performance of the rigid column.

[0067] For reference Figure 1 , Figure 9 , Figure 11 and Figure 14 In the embodiments provided above, the first support segment 1, the connecting segment 2, and the second support segment 3 not only include an inner support and an outer shell, but also a partition 6 disposed between the inner support and the outer shell. This partition 6 extends along the cross-section of the outer shell. Taking the second support segment 3 as an example, the second support segment 3 includes an inner support, an outer shell surrounding the inner support, and a plurality of partitions 6 disposed between the aforementioned inner support and the aforementioned outer shell. Any partition 6 is fixedly connected to the inner support and the outer shell, and any partition 6 extends along the cross-section of the aforementioned outer shell to reinforce the inner support and the outer shell.

[0068] In summary, the segmented design of the rigid column provided in this application not only meets the construction characteristics requirements of different areas of the rigid column, but also improves the processing technology of the rigid column and reduces the difficulty of production and assembly.

[0069] From the perspective of the construction characteristics of rigid columns, this rigid column combines a regularly shaped first support segment 1 and a horseshoe-shaped second support segment 3. The first support segment 1 is buried underground, while the second support segment 3 extends above the ground surface. Compared to the second support segment 3, the first support segment 1 has a more regular shape and can better serve as a foundation structure for support. The outer periphery of the second support segment 3 has curved panels 311 and folded panels 312. The combination of curved panels 311 and folded panels 312 can better achieve positioning and support effects with effective materials.

[0070] From the perspective of the manufacturing process of the rigid column, this rigid column combines the first support section 1, the second support section 3, and the connecting section 2 to achieve the fixed connection of the first support section 1 and the second support section 3 with different thicknesses into one unit using the connecting section 2. When the connecting section 2 is used to connect the first support section 1 and the second support section 3, both ends of the first support section 1 and the second support section 3 are provided with mounting seats 4. The two ends of the connecting section 2 can be fixedly connected to the two mounting seats 4 respectively, without having to extend into the interior of either the first support section 1 or the second support section 3 for welding. When the connecting section 2 is used to connect the first support section 1 and the second support section 3, the connecting section 2 can smoothly transition between the first support section 1 and the second support section 3 with different thicknesses, which is conducive to ensuring that each of the first reinforcing plates 12 of the first support section 1 meets the assembly size requirements and avoids the other first reinforcing plates 12 being difficult to effectively fix to the second support section 3 due to large assembly errors in some of the first reinforcing plates 12.

[0071] Based on the shape characteristics of the first support section 1, the second support section 3, and the connecting section 2, the first support section 1 can be considered as the lower cross-shaped column of the rigid column, the connecting section 2 as the middle cross-shaped column of the rigid column, and the second support section 3 as the upper horseshoe-shaped column of the rigid column. After the lower cross-shaped column, the middle cross-shaped column, and the upper horseshoe-shaped column are assembled in sequence, other auxiliary accessories can be welded around the rigid column to meet the connection requirements between the rigid column and other construction materials.

[0072] In the various embodiments provided herein, reference may be made to Figures 3 to 9 The upper horseshoe column can be manufactured according to the following steps: (1) Prepare a round tube of the same specification according to the size of the upper horseshoe column, draw a cutting line on the outside of the round tube, and build support columns at both ends of the round tube to prevent the round tube from deforming during cutting; (2) Cut the round tube along the cutting line to obtain a horseshoe semicircular plate, and make a hole at one end of the horseshoe semicircular plate; (3) Cut multiple flat plates; (4) Combine and weld the horseshoe semicircular plate and all the flat plates; (5) Insert a cross-shaped bracket into the assembled horseshoe semicircular plate and all the flat plates, and weld the horseshoe semicircular plate, flat plates and cross-shaped bracket at the same time; (6) Insert and weld the partition plate 6 into the aforementioned assembly, and weld the mounting seat 4 at the end of the aforementioned assembly. Among them, the horseshoe semicircular plate can be regarded as a curved panel 311, and all the flat plates are assembled to form a folded panel 312.

[0073] In the various embodiments provided herein, reference may be made to Figures 10 to 13 The middle cross column can be processed and manufactured according to the following steps: (1) Prepare a suitable round tube according to the first arched reinforcing plate 221 and the second arched reinforcing plate 222 of the middle cross column, draw a cutting line on the outside of the aforementioned round tube and cut to obtain the first arched reinforcing plate 221 and the second arched reinforcing plate 222; (2) Assemble and weld the cross-shaped bracket, multiple first arched reinforcing plates 221, multiple second arched reinforcing plates 222 and multiple partitions 6 into one piece.

[0074] For reference Figure 14 The lower cross column is a common rigid beam-column structure. Therefore, in the embodiments provided herein, the lower cross column can be welded with reference to relevant existing technologies.

[0075] The rigid column provided in this application can be fabricated from steel. As described above, the rigid column provided in this application includes a lower cross column, a middle cross column, and an upper horseshoe column; therefore, the rigid column provided in this application can be regarded as a horseshoe-shaped steel column.

[0076] In summary, the segmented design and welding of the rigid column provided in this application can improve the welding sequence, optimize the processing flow, control welding deformation, and ensure weld quality. The upper horseshoe column and the middle cross column of the rigid column are made by rolling and cutting round tubes, which can reduce equipment investment costs and labor intensity.

[0077] The rigid column provided in this application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this application.
