Description

Technical Field

[0001] This invention belongs to the field of building steel column structure processing and manufacturing technology, specifically involving a cross-octagonal composite column structure and its manufacturing method. Background Technology

[0002] Today, steel structures in China are becoming increasingly diversified and complex. Cross-shaped, box-shaped, and circular tube steel column structures are being used more and more in steel structure projects due to their unique advantages in building structural systems.

[0003] With the maturation of technology and the rapid development of the steel structure processing industry in my country, the single application of cross-shaped, box-shaped, and circular tube structures is gradually shifting towards combined applications of cross-shaped and box-shaped, box-shaped and circular tube, and cross-shaped and circular tube structures. Furthermore, in the design of high-rise frame structures, underground structures often use steel-reinforced concrete columns with cross-shaped or H-shaped sections, while above-ground steel columns mostly use box-shaped columns. The significant differences between underground and above-ground steel columns make the transition between them extremely important. Steel column components are generally the most crucial structural members of the entire steel structure; if their manufacturing methods are unscientific or unreasonable, it will affect the structural safety of the entire building.

[0004] Chinese invention patent (CN202010310352.2) discloses a reinforced steel column and ECC concrete composite joint and its construction method. The reinforced steel column and ECC concrete composite joint includes a cross-shaped column, four steel beam brackets, four vertically arranged annular hoops, and ECC concrete poured into the end areas of the steel column and steel beam. Each cross-shaped column includes a cross-shaped web and four cross-shaped flanges connected to the corresponding ends of the web. By using annular hoops to replace some stirrups, the production process is simplified. The use of inclined connecting plates and annular connecting plates improves the overall energy dissipation capacity; however, additional annular hoops need to be installed when installing the brackets.

[0005] Chinese invention patent (CN202011594428.5) discloses a method for manufacturing a cross-shaped support node inside a cross-shaped box-type to circular tube. First, the upper and lower nodes are self-closing; a first partition plate is welded; a middle panel is welded; then, the inner partition plate inside the circular tube is welded, and finally, the upper and lower nodes are joined together. This invention optimizes the structure of the support node by allowing the upper and lower nodes to self-close separately, enabling simultaneous processing and shortening the processing time. However, the structure is relatively complex and not suitable for octagonal column transition structures.

[0006] Octagonal column structures are a type of box column. Compared to traditional quadrilateral columns, octagonal columns are superior in avoiding stress concentration and strength. They are also easier to ensure the connection strength of beams and to weld than round columns. However, the structure of cross columns transitioning to octagonal columns does not have the same mature processing and manufacturing technology as other conventional steel structure components (such as box, H, and round tubes).

[0007] As can be seen from the above existing technology, there is no mature manufacturing process for the structure connecting the cross column and the octagonal column in the existing technology. The existing octagonal column structure has a long manufacturing cycle and is difficult to manufacture; the structural stability and safety are difficult to guarantee. Summary of the Invention

[0008] The purpose of this invention is to address the problems existing in the prior art by providing a cross-octagonal composite column structure and its manufacturing method. This solution has the advantages of simple manufacturing, short manufacturing cycle, and good safety, which greatly facilitates the design of domestic building structures and solves the processing difficulties of converting cross columns of building steel structures into octagonal columns.

[0009] To achieve the above objectives, the technical solution adopted by the present invention is: a method for manufacturing a cross-octagonal composite prism structure, comprising the following steps:

[0010] S1: Make cross pillar one and cross pillar three. Set at least two inner partition plates one between the adjacent web plate one and wing plate one of cross pillar one, and set at least one gusset plate between the adjacent wing plate three of cross pillar three.

[0011] S2: The upper cross column 1 and the lower cross column 3 are welded together to form a cross column body. The inclined panel 1 is welded between the adjacent wing plates 1 in the lower part of the cross column 1. The upper and lower parts of the inner side of the inclined panel 1 are welded to the two inner partition plates 1 respectively. The steel column panel is welded between the adjacent wing plates 1 in the upper part of the cross column 1. The steel column panel and the wing plate 1 form a box column mounting part. The bottom surface of the steel column panel is welded to the inclined panel 1. The steel column panel, the inclined panel 1 and the wing plate 1 form an octagonal cross section.

[0012] S3: Weld the H-shaped bracket to the outer surface of the inclined panel one and the wing plate one, and weld the column base plate to the bottom surface of the web plate three and the wing plate three of the cross column three.

[0013] In the above scheme, in step S1, the cross-shaped column structure is strengthened by processing the existing cross-shaped column and setting an inner partition plate between the web plate 1 and the flange plate 1, and a connecting plate between the flange plates 3. The cross-shaped column 1 and cross-shaped column 3 are processed simultaneously, accelerating production efficiency. The cross-shaped column 1 is processed in sections, and it needs to serve as a floor beam to support the corbel. The plate thickness is designed to be greater than that of the cross-shaped column 3, which serves as an inter-floor beam, to ensure sufficient strength. In step S2, the web plate 1 and flange plate 1 are welded to the web plate 3 and flange plate 3 of the cross-shaped column 3 to form a cross-shaped column body. The inclined plate 1 and flange plate 1 form an octagonal prism-shaped corbel mounting part. The corbel installation part corresponds to the box column installation part and the outline of the octagonal column, which facilitates installation and ensures structural consistency. The left and right sides of the inclined panel one are welded to the wing plate one, and the inner side of the inclined panel one is welded to the inner partition plate one to ensure the stability of the corbel installation part structure. After the inclined panel one and the inner partition plate one are welded, the steel column panel is welded separately to the wing plate one and the inclined panel one to ensure sufficient welding space and welding quality. In S3, the H-shaped corbel is welded to the outer surface of the inclined panel one and the wing plate one to form a connection of multiple surfaces to improve stability. The crossbeam is connected by welding the H-shaped corbel, and the column base plate is set to support the bottom surface and facilitate installation.

[0014] Furthermore, an installation hole is provided on at least one of the inner partition plates, and at least one pipe support is welded on the web plate. A downpipe is provided inside the pipe support, passing through the installation hole. An installation hole is provided in the middle of at least one inclined panel, and the downpipe passes through the installation hole when the inclined panel is installed.

[0015] The downpipe is positioned and installed using a pipe bracket. The downpipe passes through a mounting hole and its bottom end protrudes from the mounting hole. The downpipe is then placed inside the column structure to protect it and extend its service life. Water from the upper building is drained through the downpipe. The integrated design of the downpipe and the column reduces the steps required for subsequent water pipe installation, shortens the production cycle, and minimizes damage to the exterior wall during installation.

[0016] Furthermore, the following steps are also included: S4: Install an octagonal column on the top surface of the box column installation part, insert the second downpipe inside the octagonal column with the top of the first downpipe, so that the outer contour of the octagonal column corresponds to the outer contour of the box column installation part and is temporarily fixed, reserve a manhole at the lower end of the inclined plate second of the octagonal column, weld the second web plate of the octagonal column to the corresponding first web plate through the manhole, and then weld the second wing plate and the second inclined plate of the octagonal column to the corresponding first wing plate and the first inclined plate respectively, and weld the manhole plate.

[0017] The box column mounting section is consistent with the outer contour of the octagonal column, which facilitates installation and positioning. It can be temporarily fixed by spot welding connectors. The second downpipe is connected to the top of the first downpipe to draw water down from the top. Space is left through the manhole to weld the second web plate to the corresponding first web plate. Then, the second wing plate and the second inclined plate are welded to the first wing plate and the first inclined plate, respectively. The manhole plate is then welded to complete the connection between the box column mounting section and the octagonal column, ensuring the stability of the connection.

[0018] Furthermore, the octagonal column is manufactured through the following steps: First, a cross-shaped column 2 is made. Several inner partition plates 2 are set between adjacent web plates 2 and wing plates 2 of the cross-shaped column 2. Mounting holes 2 are opened on the inner partition plates 2. Then, at least one pipe support 2 is welded on the web plate 2 of the cross-shaped column 2. A downpipe 2 passing through the mounting hole 2 is set in the pipe support 2. An inclined plate 2 is spot welded between adjacent wing plates 2 of the cross-shaped column 2 to form a welding bevel. A strip-shaped gap and a manhole are reserved. Finally, the wing plates 2 and the inclined plate 2 are automatically welded by a track and a submerged arc welding machine.

[0019] Several inner partition plates are installed on the cross column 2 to reinforce the column. The downpipe 2, which passes through the installation hole 2, is installed through the pipe support 2 to draw water from the upper building down. The integrated installation protects the pipe, simplifies the later pipe installation work, and shortens the work cycle. The strip gap is formed by spot welding the inclined panel 2 to facilitate the use of the track for submerged arc automatic welding. A manhole is left for welding the web plate.

[0020] Furthermore, during submerged arc welding, the bottom of the track is temporarily welded to the second wing plate via a connecting rod. After the submerged arc welding is completed, the connection is cut open.

[0021] The bottom of the track is temporarily fixed to the second wing plate by welding the connecting rod, which facilitates the movement of the submerged arc welding machine. After the welding is completed, the connection is cut open and the track is moved to the next second wing plate for fixing and continued welding.

[0022] Furthermore, in the manufacture of the H-shaped corbel, firstly, the two corbel flange plates and the corbel web plate are welded together to form an H-shaped steel structure, and then stiffening plates are welded between the two sides of the corbel web plate and the corbel flange plates respectively.

[0023] The structural strength and load-bearing capacity of the H-shaped bracket are improved by welding stiffening plates.

[0024] Furthermore, the bracket flange plate has an annular groove corresponding to the outer contour of the bracket mounting part, and four H-shaped brackets are welded at 90° intervals on the outer ring of the bracket mounting part. The inner partition plate corresponds to the height of the bracket flange plate of the H-shaped bracket.

[0025] The annular groove connects to a wing plate and two inclined plates, improving the stability of the connection. The inner partition plate corresponds to the height of the corbel flange plate to improve the strength of the connection with the H-shaped corbel, ensuring the stability and safety of the structure.

[0026] A cross-octagonal composite column structure includes a cross column, which is welded together from an upper cross column 1 and a lower cross column 3. At least two inner partition plates 1 are provided between adjacent web plates 1 and wing plates 1 of the cross column 1. At least one gusset plate is provided between adjacent wing plates 3 of the cross column 3. An inclined panel 1 is welded between adjacent wing plates 1 in the lower part of the cross column 1. The upper and lower parts of the inner side of the inclined panel 1 are respectively welded to two inner partition plates 1. The inclined panel 1 and the wing plates 1 form an octagonal bracket mounting part. A steel column panel is welded between adjacent wing plates 1 in the upper part of the cross column 1. The steel column panel and the wing plates 1 form an octagonal box column mounting part. The bottom surface of the steel column panel is welded to the inclined panel 1. An H-shaped bracket is welded to the bracket mounting part. A column base plate is welded to the bottom surface of the web plates 3 and wing plates 3 of the cross column 3.

[0027] In the above scheme, the cross-shaped column structure is strengthened by processing the existing cross-shaped column and setting an inner partition plate and a connecting plate. The cross-shaped column body is formed by welding the web plate 1 and wing plate 1 of cross-shaped column 1 to the web plate 3 and wing plate 3 of cross-shaped column 3. It can be processed in sections simultaneously. Cross-shaped column 1 needs to support the corbel as a floor beam. The plate thickness is designed to be greater than that of cross-shaped column 3 as an inter-floor beam to ensure sufficient strength. The lower middle part of cross-shaped column 1 is welded with a sloping panel 1. The left and right sides of the sloping panel 1 are welded to the wing plate 1. The inner side of the sloping panel 1 is welded to the inner partition plate 1 to ensure the stability of the corbel installation structure. The octagonal prism corbel installation part corresponds to the outline of the box column installation part and the octagonal column for easy installation and to ensure structural consistency. After the sloping panel 1 and inner partition plate 1 are welded, the steel column panel is welded separately to the wing plate 1 and sloping panel 1 to ensure sufficient welding space and welding quality. The crossbeam is connected by welding H-shaped corbels. A column base plate is set to support the bottom of the column and facilitate installation.

[0028] Furthermore, a connecting lug is provided at the top of one of the wing plates of the cross-shaped column.

[0029] A connecting lug is provided at the top of the wing plate to facilitate the connection and fixation of the upper column.

[0030] Furthermore, at least one of the inner partition plates is provided with a mounting hole, and at least one pipe support is welded to the web plate. A drain pipe is provided inside the pipe support, passing through the mounting hole, and the drain pipe extends out from the mounting hole three in the middle of the inclined plate.

[0031] The downpipe is installed by a pair of pipe supports. The downpipe passes through the mounting hole 1 on the inner partition 1 and the mounting hole 3 on the inclined panel 1, so that water is drawn out and discharged from the upper building.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] 1. Provides a cross-octagonal composite column structure and manufacturing method, applicable to the transition between underground and above-ground structures, providing a reference for building structural design and solving the manufacturing problem of converting cross-shaped columns to octagonal columns in building steel structures;

[0034] 2. Adopting a conventional structure, it is easy to manufacture. It transforms the cross-shaped column into an octagonal column structure with a natural transition. It is equipped with an inner partition and H-shaped brackets are installed on the octagonal bracket mounting part. The bracket flange plate is equipped with an annular groove to ensure the overall stability and safety of the structure. The steel column panel is welded separately to ensure the quality of the welding at the inner partition and also to meet the strength requirements of the box column mounting part.

[0035] 3. By using a segmented manufacturing method, the two end columns and H-shaped brackets can be manufactured simultaneously, and assembly is convenient, reducing the manufacturing cycle; by setting downpipes inside the column structure to protect the water pipes, the subsequent water pipe installation steps are reduced, the production cycle is shortened, and damage to the exterior wall is reduced.

[0036] 4. By reserving manholes, it is convenient to weld the box column installation part to the internal cross column web of the octagonal column, thus ensuring structural strength;

[0037] 5. When assembling the cross-column to octagonal column structure, reasonable assembly and welding procedures were formulated based on relevant industry standards, ensuring good operability of concealed welds inside the octagonal column and thus guaranteeing the welding quality between various plates. Based on national standard recommendations, bevels were designed to reduce the filler volume of welds while ensuring welding quality, and reasonable welding process parameters were selected. By setting tracks on the wing plates of the octagonal column box body for automatic submerged arc welding of the octagonal box column, welding stability was achieved, production efficiency and welding quality were improved, the production cycle was shortened, and the use of welding materials was greatly reduced.

[0051] Example 1

[0052] like Figure 1-4 As shown, a method for manufacturing a cross-octagonal composite prism structure includes the following steps:

[0053] S1: Make cross post 1 and cross post 3. Set at least two inner partition plates 8 between the adjacent web plates 10 and wing plates 5 of cross post 1, and set at least one gusset plate 4 between the adjacent wing plates 7 of cross post 3.

[0054] S2: The upper cross column 1 and the lower cross column 3 are welded together to form a cross column body. The inclined plate 13 is welded between the adjacent wing plates 5 in the lower part of the cross column 1. The upper and lower parts of the inner side of the inclined plate 13 are welded to the two inner partition plates 8 respectively. The steel column panel 16 is welded between the adjacent wing plates 5 in the upper part of the cross column 1. The steel column panel 16 and the wing plate 5 form a box column mounting part. The bottom surface of the steel column panel 16 is welded to the inclined plate 13. The steel column panel 16, the inclined plate 13 and the wing plate 5 form an octagonal cross section.

[0055] S3: Weld the H-shaped bracket to the outer surface of the inclined panel 13 and the wing plate 5, and weld the column base plate 15 to the bottom surface of the web plate 12 and the wing plate 7 of the cross column 33.

[0056] In the above scheme, in step S1, the cross-shaped column structure is strengthened by processing the existing cross-shaped column and setting an inner partition plate 8 between the web plate 10 and the flange plate 5, and a connecting plate 4 between the flange plates 7. The cross-shaped column 1 and cross-shaped column 3 are processed simultaneously, which speeds up the production efficiency. The cross-shaped column 1 needs to be used as a floor beam to support the corbel. The plate thickness is designed to be greater than that of the cross-shaped column 3, which is used as an inter-floor beam, to ensure sufficient strength. In step S2, the web plate 10 and the flange plate 5 are welded to the web plate 312 and the flange plate 37 of the cross-shaped column 3 to form a cross-shaped column body. The octagonal corbel installation part corresponds to the box column installation part and the outline of the octagonal column, which facilitates installation and ensures structural consistency. The inclined panel 13 The left and right sides are welded to the wing plate 5, and the inner side of the inclined panel 13 is welded to the inner partition plate 8 to ensure the stability of the bracket installation structure. After the inclined panel 13 and the inner partition plate 8 are welded, the steel column panel 16 is welded separately to the wing plate 5 and the inclined panel 13 to ensure sufficient welding space and welding quality. In S3, the crossbeam is connected by welding H-shaped brackets, and the column base plate 15 is set to support the bottom surface and facilitate installation.

[0057] Furthermore, in the process of manufacturing the H-shaped corbel, the two corbel flange plates 25 and the corbel web plate 26 are first welded together to form an H-shaped steel structure, and then stiffening plates 27 are welded between the two sides of the corbel web plate 26 and the corbel flange plates 25 respectively.

[0058] The structural strength and load-bearing capacity of the H-type bracket are improved by welding stiffening plates 27.

[0059] The angle between the stiffening plate 27 and the corbel web plate 26 is between 30° and 70°, which makes the structure stable.

[0060] Furthermore, the bracket flange plate 25 has an annular groove corresponding to the outer contour of the bracket mounting part, and four H-shaped brackets are welded at 90° intervals on the outer ring of the bracket mounting part. The inner partition plate 8 corresponds to the height of the bracket flange plate 25 of the H-shaped bracket.

[0061] The annular groove connects to a wing plate 5 and two inclined plates 13, improving the stability of the connection. The inner partition plate 8 corresponds in height to the corbel flange plate 25 to improve the strength of the connection with the H-shaped corbel, ensuring the stability and safety of the structure.

[0062] A cross-octagonal composite column structure includes a cross column, which is welded together by an upper cross column 1 and a lower cross column 3. At least two inner partition plates 8 are provided between adjacent web plates 10 and wing plates 5 of the cross column 1. At least one connecting plate 4 is provided between adjacent wing plates 7 of the cross column 3. An inclined plate 13 is welded between adjacent wing plates 5 in the lower part of the cross column 1. The upper inner surface of the inclined plate 13... The upper and lower parts are respectively welded to the two inner partition plates 8. The inclined panel 13 and the wing plate 5 form an octagonal prism bracket mounting part. Steel column panels 16 are welded between adjacent wing plates 5 on the upper part of the cross column 1. The steel column panels 16 and the wing plates 5 form an octagonal prism box column mounting part. The bottom surface of the steel column panels 16 is welded to the inclined panel 13. H-shaped brackets are welded on the bracket mounting part. The web plate 312 and the bottom surface of the wing plate 37 of the cross column 33 are welded to the column base plate 15.

[0063] In the above scheme, the cross-shaped column structure is strengthened by processing the existing cross-shaped column and setting an inner partition plate 8 and a connecting plate 4. The cross-shaped column body is formed by welding the web plate 10 and flange plate 5 of cross-shaped column 1 to the web plate 12 and flange plate 7 of cross-shaped column 3. It can be processed in sections simultaneously. Cross-shaped column 1 needs to support the corbel as a floor beam. The plate thickness is designed to be greater than that of cross-shaped column 3, which serves as an inter-floor beam, to ensure sufficient strength. The lower part of cross-shaped column 1 is welded with a sloping panel 13. The left and right sides of the sloping panel 13 are connected to the corbel. The inner side of the wing plate 13 is welded to the inner partition plate 8 to ensure the stability of the corbel installation structure. The octagonal corbel installation corresponds to the outline of the box column installation and the octagonal column, facilitating installation and ensuring structural consistency. After the sloping panel 13 and the inner partition plate 8 are welded, the steel column panel 16 is separately welded to the wing plate 5 and the sloping panel 13 to ensure sufficient welding space and welding quality. H-shaped corbels are welded to connect the crossbeams, and a column base plate 15 is provided to support the bottom of the column and facilitate installation.

[0079] like Figure 5-7 As shown, this embodiment presents a cross-octagonal composite column structure and its manufacturing method, which are further optimized based on Embodiment 1:

[0080] A method for manufacturing a cross-octagonal composite column structure further includes: opening an installation hole 1 on at least one of the inner partition plates 8; welding at least one pipe support 20 on the web plate 10; providing a drain pipe 22 passing through the installation hole 1 inside the pipe support 20; and opening an installation hole 3 in the middle of at least one inclined panel 13, through which the drain pipe 22 passes when the inclined panel 13 is installed.

[0081] The downpipe 22 is installed and positioned using pipe bracket 20. A mounting hole 1 allows the downpipe 22 to pass through, and the bottom end of the downpipe 22 protrudes from the mounting hole 3. The downpipe 22 is housed inside the column structure, protecting it and extending its service life. Water from the upper building is drained through the downpipe 22. The integrated design of the downpipe 22 and the column reduces the number of steps required for subsequent water pipe installation, shortens the production cycle, and minimizes damage to the exterior wall during installation. Stainless steel pipes are preferred for the downpipe.

[0082] A cross-octagonal composite column structure, further optimized based on Example 1:

[0083] Furthermore, at least one of the inner partition plates 8 has an installation hole 1, and at least one pipe support 20 is welded to the web plate 10. A downpipe 22 is provided inside the pipe support 20, passing through the installation hole 1, and the downpipe 22 exits from the installation hole 3 in the middle of the inclined panel 13.

[0084] The downpipe 22 is installed via pipe bracket 20, and water is drawn out and discharged from the upper building through mounting holes 1 on the inner partition 8 and mounting holes 3 on the inclined panel 13. Pipe bracket 20 includes pipe clamp 17 and support rod 18.

[0085] Example 3

[0086] like Figure 8-11 As shown, the manufacturing method of a cross-octagonal composite column structure in this embodiment is further optimized based on Embodiment 2:

[0087] Furthermore, the following steps are also included: S4: Install an octagonal column on the top surface of the box column mounting part, insert the drain pipe 23 inside the octagonal column with the top of the drain pipe 22, so that the outer contour of the octagonal column corresponds to the outer contour of the box column mounting part and is temporarily fixed, reserve a manhole at the lower end of the inclined plate 2 14 of the octagonal column, weld the web plate 2 11 of the octagonal column to the corresponding web plate 10 through the manhole, and then weld the wing plate 2 6 and the inclined plate 2 14 of the octagonal column to the wing plate 1 5 and the inclined plate 13 respectively, and weld the manhole plate 24.

[0088] The box column mounting part is consistent with the outer contour of the octagonal column, which facilitates installation and positioning. It can be temporarily fixed by spot welding connectors. The top of the downpipe 23 is inserted and connected to the top of the downpipe 22 to draw water down from the top. Space is left through the manhole to weld the web plate 21 to the corresponding web plate 10. Then, the wing plate 26 and the inclined plate 24 are welded to the wing plate 5 and the inclined plate 13 respectively. The manhole plate 24 is then welded to complete the docking of the box column mounting part and the octagonal column, ensuring the stability of the connection.

[0089] Two manholes are located opposite each other on the octagonal prism.

[0090] Furthermore, the octagonal column is manufactured through the following steps: First, a cross-shaped column 2 is made. Several inner partitions 9 are set between the adjacent web plates 11 and wing plates 6 of the cross-shaped column 2. Mounting holes 2 are opened on the inner partitions 9. Then, at least one pipe support 21 is welded to the web plate 11 of the cross-shaped column 2. A downpipe 23 passing through the mounting hole 2 is set in the pipe support 21. An inclined plate 24 is spot welded between the adjacent wing plates 6 of the cross-shaped column 2 to form a welding bevel. A strip gap and a manhole are reserved. Finally, the wing plates 6 and the inclined plate 24 are automatically welded by a track and a submerged arc welding machine.

[0091] Several inner partition plates 29 are installed on the cross column 22 to reinforce the column. The downpipe 23, which passes through the installation hole 2, is installed through the pipe support 21 to draw water from the upper building down. The integrated installation protects the pipe, simplifies the later pipe installation work, and shortens the work cycle. The strip gap is formed by spot welding the inclined panel 214 to facilitate the use of the track for submerged arc automatic welding. A manhole is left for welding the web plate.

[0092] Downpipe 23 is made of stainless steel. The track consists of two angle steel rails 29 and several fixing rods 30 located between the angle steel rails 29.

[0093] Furthermore, during submerged arc welding, the bottom of the track is temporarily welded to the second wing plate 6 via a connecting rod. After the submerged arc welding is completed, the connection is cut open.

[0094] The bottom of the track is temporarily fixed to the second wing plate 6 by welding the connecting rod, which facilitates the movement of the submerged arc welding machine. After the welding is completed, the connection is cut open and the track is moved to the next wing plate 6 for fixing and continued welding.

[0095] The connecting rod is made of steel bars. Use a cutting machine to cut the connection or cut the steel bars.

[0096] Furthermore, a connecting lug 28 is provided on the top of the wing plate 5 of the cross column.

[0097] When installing the octagonal column, the cross column 2 is also provided with a connecting lug 28, which is temporarily fixed to the cross column 1 by a clamp 19. The clamp 19 is connected by bolts or welding.

[0098] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
