Description

Technical Field

[0001] This invention relates to stiffened columns and their splicing and welding methods. Background Technology

[0002] The reinforced cross column is an important structural form in modern construction engineering. Its basic structure consists of steel sections encased in concrete. This structure has many advantages, such as high seismic resistance. The application of reinforced cross columns is particularly important in high-rise buildings, large structures, and earthquake-prone areas. By encasing the steel sections in concrete, the reinforced cross column not only improves the overall load-bearing capacity but also effectively reduces the cross-sectional dimensions of the components, thereby saving space and reducing project costs.

[0003] In the existing technology, the rigid cross column assembly welding uses a combination of one H-beam and two T-beams. Because the combined T-shaped structure has internal partitions and the steel structure has wide flanges, the obstruction of the above structures prevents the welding robot from extending the welding torch into the welding area, and welding can only be done manually, resulting in low welding efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a technical solution for stiffening columns and their splicing and welding methods to address the shortcomings of existing technologies. This solution not only improves the overall stability and reliability of the stiffening columns, but also allows welding robots to extend their welding torches into the welding area, increasing welding efficiency. It facilitates splicing and welding, is suitable for industrial production, and greatly improves production efficiency. This splicing and welding process makes the quality controllable during processing and increases the yield rate.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] The stiffening column is characterized by comprising:

[0007] At least one first component;

[0008] And at least one second component, wherein the first component is spliced ​​to the second component, and the first component and the second component are vertically fixed by welding;

[0009] The above structural design not only improves the overall stability and reliability of the stiffening column, but also allows the welding robot to extend the welding torch into the welding area, improving welding efficiency, facilitating splicing and welding, adapting to industrial production, and greatly improving production efficiency.

[0010] Furthermore, the first and second components include web plate assemblies and / or I-beams to meet the splicing and welding requirements of stiffened columns of different shapes.

[0011] Furthermore, the web assembly includes an integral web with connecting flanges or two single webs of matching dimensions, to meet the requirements of stiffened column splicing and welding in different situations and improve the flexibility of stiffened column splicing and welding.

[0012] Furthermore, both the integral web and the I-beam are equipped with slots, the length of which is half the length of the integral web or the I-beam. This helps to improve the overall connection strength of the stiffening column and makes the whole structure more stable and reliable.

[0013] Furthermore, the flange plate is provided with an installation port. The inner edge of the installation port and slot and one side of the single web plate are each provided with at least one bevel. The inclination angle of the bevel is 25° to 45°. During welding, the welding torch can deposit metal along the bevel, which improves the welding quality of the weld. A smaller welding angle requires less metal to be deposited, reducing welding and heat input, thereby reducing the deformation caused by welding. The angle of the bevel can be adjusted according to the welding performance of the welding robot.

[0014] Furthermore, when welding a single web plate, assembling the single web plate at an angle to the welding surface helps to reduce cooling shrinkage deformation during welding and reduces subsequent correction work.

[0015] Furthermore, when the flange plates are connected by plug welds, a steel backing strip is provided on the side away from the bevel to prevent the weld from burning through.

[0016] Furthermore, the I-beam can be an I-shaped structure with equal lengths of both flanges or an I-shaped structure with the outer flange being shorter than the inner flange.

[0017] Furthermore, it also includes several inner partitions, which are welded between the first component and the second component.

[0018] The splicing and welding method for stiffened columns as described above is characterized by including the following steps:

[0019] S1. Material cutting: Select a suitable steel plate shape, which includes the first component and the second component;

[0020] S2. Assemble and position the first and second components, and perform a first and second component straightening through flame straightening or mechanical straightening.

[0021] S3. The scanning area between the first component and the second component is scanned by the scanner of the welding robot, and the stiffening column is obtained by welding along the weld seam between the first component and the second component.

[0022] S4. Reassemble and position the stiffening columns that are not welded properly. Once the stiffening columns that meet the dimensions are assembled, perform secondary straightening through flame straightening or mechanical straightening.

[0023] S5. After straightening, the stiffening column is inspected. The stiffening column that fails the inspection is straightened a second time by flame straightening or mechanical straightening. The stiffening column that passes the inspection is the finished product.

[0024] This splicing and welding process makes the quality controllable during processing and improves the yield rate.

[0025] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0026] 1. This invention not only improves the overall stability and reliability of the stiffening column, but also enables the welding robot to extend the welding torch into the welding area, improving welding efficiency, facilitating splicing and welding, adapting to industrial production, and greatly improving production efficiency.

[0027] 2. This splicing and welding process makes the quality controllable during processing and improves the yield rate. Attached Figure Description

Detailed Implementation

[0056] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0057] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0058] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0059] Example 1

[0060] like Figures 1 to 9 As shown, the rigid column of the present invention includes a first component, a second component and several inner partitions 3. The first component is spliced ​​to the second component, and the first component and the second component are vertically fixed by welding.

[0061] The inner partition 3 is vertically welded between the first component and the second component.

[0062] Both the first and second components include web plate assemblies to meet the splicing and welding requirements of stiffened columns of different shapes.

[0063] The web assembly includes an integral web with flange plates 4 connected to it, which can meet the requirements of stiffened column splicing and welding in different occasions and improve the flexibility of stiffened column splicing and welding.

[0064] The integral web in this embodiment includes a first web 1 and a second web 2, both of which are made of flat steel plates. The first web 1 is provided with a first slot 101, and the second web 2 is provided with a second slot 201. The length of the first slot 101 is half the length of the first web 1, and the length of the second slot 201 is half the length of the second web 2. This is beneficial to improving the overall connection strength of the stiffening column and making the whole structure more stable and reliable.

[0065] The flange plate 4 is provided with a mounting port 401. The mounting port 401, the inner edge of the slot and one side of the single web plate are all provided with bevels. The mounting port 401 is a first bevel 402, and the inner edge of the slot and one side of the single web plate are second bevels 8. During welding, the welding torch can deposit metal along the bevels to improve the welding quality of the weld.

[0066] The inclination angle of the first bevel 402 and the second bevel 8 is 25° to 45°, preferably 30°. A smaller welding angle requires less cladding metal, reduces welding, reduces heat input, and thus reduces welding deformation. The bevel opening angle is adjusted according to the welding performance of the welding robot.

[0067] When the flange plate 4 is connected by plug weld, a steel liner 5 is provided on the side away from the bevel to prevent the weld from burning through.

[0068] The above structural design not only improves the overall stability and reliability of the stiffening column, but also allows the welding robot to extend the welding torch into the welding area, improving welding efficiency, facilitating splicing and welding, adapting to industrial production, and greatly improving production efficiency.

[0069] like Figure 26 The diagram illustrates the splicing and welding method for the stiffening column of the present invention, comprising the following steps:

[0070] S1. Material cutting: Select a suitable steel plate shape, which includes a first web 1 and a second web 2.

[0071] S2. Assemble and position the first web plate 1 and the second web plate 2, and perform a first correction on the first web plate 1 and the second web plate 2 by flame straightening or mechanical straightening.

[0072] S3. The scanning area between the first web plate 1 and the second web plate 2 is scanned by the scanner of the welding robot, and the stiffened column is obtained by welding along the weld seam between the first web plate 1 and the second web plate 2.

[0073] When welding the first web 1 and the second web 2, weld the first weld 6 first, then weld the second weld 7. Weld the first weld 6 and the second weld 7 in the order of ① to ⑤. After the first weld 6 has cooled, observe the degree of deformation of the welding material. If it exceeds the allowable deformation value, flame straightening is performed. The specific flame temperature is selected as 600 to 800℃, preferably 700℃. Flame straightening is performed along the length of the weld to eliminate residual stress in the weld.

[0074] After the flame straightening is completed and cooled, the second weld 7 is welded again. The welding sequence is root pass welding - filler weld - capping weld. The capping weld is automatically welded by a robot, or submerged arc welding can be selected. When submerged arc welding is selected, the flux needs to be dried. Similarly, if flame straightening is required, the welding process described above is used to eliminate welding stress.

[0075] S4. Reassemble and position the stiffening columns that are not welded properly. Once the stiffening columns that meet the dimensions are assembled, perform secondary straightening through flame straightening or mechanical straightening.

[0076] After the first web plate 1 and the second web plate 2 are welded, the inner diaphragm 3 is assembled first. After the inner diaphragm 3 is positioned, it is welded and straightened to keep the inner diaphragm 3 flush. Then the flange plate 4 is assembled.

[0077] The flange plate 4 is provided with an installation port 401, and the edge of the installation port 401 is provided with a first bevel 402. During assembly, the flange plate 4 at the corresponding position is placed on the inner partition plate 3, and then welded. The flange plate 4 is welded using a plug weld. For aesthetic purposes and to adapt to industrial production, a steel liner 5 is placed on the side of the second web plate 2 located at the second bevel 8. During welding, molten metal drips may occur. If the flange plate 4 is welded... Figure 8 As shown, weld ① to ④ on one side first, then weld ④ to ⑧ on the other side, and finally weld the cover ⑨.

[0078] S5. After straightening, the stiffening column is inspected. The stiffening column that fails the inspection is straightened a second time by flame straightening or mechanical straightening. The stiffening column that passes the inspection is the finished product.

[0079] This splicing and welding process makes the quality controllable during processing and improves the yield rate.

[0080] Example 2

[0081] like Figures 10 to 15 As shown, the rigid column of the present invention includes a first component, a second component and several inner partitions 3. The first component is spliced ​​to the second component, and the first component and the second component are vertically fixed by welding.

[0082] The inner partition 3 is vertically welded between the first component and the second component.

[0083] The first component includes a web assembly, and the second component includes a first I-beam 9, which meets the splicing and welding requirements of stiffened columns of different shapes. The first I-beam 9 has an I-shaped structure with equal lengths of two flange plates 4 on both sides.

[0084] The web assembly includes an integral web with flange plates 4 connected to it, which can meet the requirements of stiffened column splicing and welding in different occasions and improve the flexibility of stiffened column splicing and welding.

[0085] In this embodiment, the integral web is the first web 1, the I-beam is the first I-beam 9, the first web 1 is provided with a first slot 101, and the first I-beam 9 is provided with a third slot 901. The length of the first slot 101 is 1 / 2 of the length of the first web 1, and the length of the third slot 901 is 1 / 2 of the length of the first I-beam 9. This is beneficial to improving the overall connection strength of the stiffening column and making the whole structure more stable and reliable.

[0086] The flange plate 4 is provided with a mounting port 401. The mounting port 401, the inner edge of the slot and one side of the single web plate are all provided with bevels. The mounting port 401 is a first bevel 402, and the inner edge of the slot and one side of the single web plate are second bevels 8. During welding, the welding torch can deposit metal along the bevels to improve the welding quality of the weld.

[0087] The bevel angle is 25° to 45°, preferably 30°. A smaller welding angle requires less cladding metal, reduces welding, reduces heat input, and thus reduces welding deformation. The bevel angle is adjusted according to the welding performance of the welding robot.

[0088] When the flange plate 4 is connected by plug weld, a steel liner 5 is provided on the side away from the bevel to prevent the weld from burning through.

[0089] The above structural design not only improves the overall stability and reliability of the stiffening column, but also allows the welding robot to extend the welding torch into the welding area, improving welding efficiency, facilitating splicing and welding, adapting to industrial production, and greatly improving production efficiency.

[0090] like Figure 26 The diagram illustrates the splicing and welding method for the stiffening column of the present invention, comprising the following steps:

[0091] S1. Cutting and blanking: Select a suitable steel plate shape, which includes the first web plate 1 and the first I-beam 9.

[0092] S2. Assemble and position the first web plate 1 and the first I-beam 9, and straighten the first web plate 1 and the first I-beam 9 once by flame straightening or mechanical straightening.

[0093] S3. The scanning area between the first web plate 1 and the first I-beam 9 is scanned by the scanner of the welding robot, and the stiffened column is obtained by welding along the weld between the first web plate 1 and the first I-beam 9.

[0094] When welding the first web plate 1 and the first I-beam 9, weld the first weld 6 first, then weld the second weld 7. Weld the first weld 6 and the second weld 7 in the order of ① to ⑤. After the first weld 6 has cooled, observe the deformation of the welding material. If it exceeds the allowable deformation value, flame straightening is performed. The specific flame temperature is selected as 600 to 800℃, preferably 700℃. Flame straightening is performed along the length of the weld to eliminate residual stress in the weld.

[0095] After the flame straightening is completed and cooled, the second weld 7 is welded again. The welding sequence is root pass welding - filler weld - capping weld. The capping weld is automatically welded by a robot, or submerged arc welding can be selected. When submerged arc welding is selected, the flux needs to be dried. Similarly, if flame straightening is required, the welding process described above is used to eliminate welding stress.

[0096] S4. Reassemble and position the stiffening columns that are not welded properly. Once the stiffening columns that meet the dimensions are assembled, perform secondary straightening through flame straightening or mechanical straightening.

[0097] After the first web plate 1 and the first I-beam 9 are welded, the inner diaphragm 3 is assembled first. After the inner diaphragm 3 is positioned, it is welded and straightened to keep the inner diaphragm 3 flush. Then the flange plate 4 is assembled. After welding and flame straightening, the dimensions are inspected and corrected.

[0098] The flange plate 4 is provided with an installation port 401, and the edge of the installation port 401 is provided with a first bevel 402. During assembly, the flange plate 4 at the corresponding position is placed on the inner partition plate 3, and then welded. The flange plate 4 is welded using a plug weld. For aesthetic purposes and to adapt to industrial production, a steel liner 5 is placed on the side of the first web plate 1 located at the second bevel 8. During welding, dripping molten metal may occur. Figure 8 As shown, weld ① to ④ on one side first, then weld ④ to ⑧ on the other side, and finally weld the cover ⑨.

[0099] S5. After straightening, the stiffening column is inspected. The stiffening column that fails the inspection is straightened a second time by flame straightening or mechanical straightening. The stiffening column that passes the inspection is the finished product.

[0100] This splicing and welding process makes the quality controllable during processing and improves the yield rate.

[0101] Example 3

[0102] like Figures 16 to 20As shown, the rigid column of the present invention includes a first component, a second component and several inner partitions 3. The first component is spliced ​​to the second component, and the first component and the second component are vertically fixed by welding.

[0103] The inner partition 3 is vertically welded between the first component and the second component.

[0104] The above structural design not only improves the overall stability and reliability of the stiffening column, but also allows the welding robot to extend the welding torch into the welding area, improving welding efficiency, facilitating splicing and welding, adapting to industrial production, and greatly improving production efficiency.

[0105] The first component includes a first I-beam 9, which has an I-shaped structure with equal lengths of two side flanges 4. The second component includes a web assembly to meet the splicing and welding requirements of stiffened columns of different shapes.

[0106] Alternatively, the first component may include a wider third web 10 and two narrower fourth webs 11, with two flanges 4 pre-connected to the third web 10, and the two fourth webs 11 connected to both sides of the third web 10.

[0107] The web plate assembly includes two single web plates of matching dimensions connected by flange plates 4, which can meet the requirements of stiffened column splicing welding in different occasions and improve the flexibility of stiffened column splicing welding.

[0108] In this embodiment, the single web plate uses a third web plate 10 and a fourth web plate 11.

[0109] The flange plate 4 is provided with a mounting opening 401, which has a first bevel 402. A second bevel 8 is provided on one side of the single web plate. During welding, the welding torch can deposit metal along the bevel, improving the weld quality. The inclination angle of the first bevel 402 and the second bevel 8 is 25° to 45°, preferably 30°. A smaller welding angle requires less metal to be deposited, reducing welding and heat input, thereby reducing welding deformation. The bevel opening angle is adjusted according to the welding performance of the welding robot.

[0110] When welding a single web plate, assembling it at an angle to the welding surface helps reduce cooling shrinkage deformation during welding and minimizes subsequent straightening work. The inclination angle of the single web plate is β, preferably 5°, which can be selected according to the actual working conditions.

[0111] When the flange plate 4 is connected by plug weld, a steel liner 5 is provided on the side away from the bevel to prevent the weld from burning through.

[0112] like Figure 26 The diagram illustrates the splicing and welding method for the stiffening column of the present invention, comprising the following steps:

[0113] S1. Cutting and blanking: Select a suitable steel plate shape, which includes the first I-beam 9, the third web 10, and the fourth web 11.

[0114] S2. Assemble and position the first I-beam 9, the third web plate 10 and the fourth web plate 11, and straighten the first I-beam 9, the third web plate 10 and the fourth web plate 11 once by flame straightening or mechanical straightening.

[0115] S3. The scanning area between the first I-beam 9, the third web plate 10 and the fourth web plate 11 is scanned by the scanner of the welding robot, and the stiffened column is obtained by welding along the weld between the first I-beam 9, the third web plate 10 and the fourth web plate 11.

[0116] When welding the first I-beam 9, the third web 10, and the fourth web 11, weld the first weld 6 first, then weld the second weld 7. Weld the first weld 6 and the second weld 7 in the order of ① to ⑤. After the first weld 6 has cooled, observe the degree of deformation of the welding material. If it exceeds the allowable deformation value, flame straightening is performed. The specific flame temperature is selected as 600 to 800℃, preferably 700℃. Flame straightening is performed along the length of the weld to eliminate residual stress in the weld.

[0117] After the flame straightening is completed and cooled, the second weld 7 is welded again. The welding sequence is root pass welding - filler weld - capping weld. The capping weld is automatically welded by a robot, or submerged arc welding can be selected. When submerged arc welding is selected, the flux needs to be dried. Similarly, if flame straightening is required, the welding process described above is used to eliminate welding stress.

[0118] S4. Reassemble and position the stiffening columns that are not welded properly. Once the stiffening columns that meet the dimensions are assembled, perform secondary straightening through flame straightening or mechanical straightening.

[0119] After the first I-beam 9, the third web plate 10 and the fourth web plate 11 are welded, the inner diaphragm 3 is assembled first. After the inner diaphragm 3 is positioned, it is welded and straightened to keep the inner diaphragm 3 flush. Then the flange plate 4 is assembled.

[0120] The flange plate 4 is provided with an installation port 401, and the edge of the installation port 401 is provided with a first bevel 402. During assembly, the flange plate 4 at the corresponding position is placed on the inner partition plate 3, and then welded. The flange plate 4 is welded using a plug weld. For aesthetic purposes and to adapt to industrial production, steel lining strips 5 are placed on the side of the third web plate 10 and the fourth web plate 11 located at the second bevel 8. During welding, molten droplets may leak. If the flange plate 4 is welded... Figure 8 As shown, weld ① to ④ on one side first, then weld ④ to ⑧ on the other side, and finally weld the cover ⑨.

[0121] S5. After straightening, the stiffening column is inspected. The stiffening column that fails the inspection is straightened a second time by flame straightening or mechanical straightening. The stiffening column that passes the inspection is the finished product.

[0122] This splicing and welding process makes the quality controllable during processing and improves the yield rate.

[0123] Example 4

[0124] like Figure 21 As shown, the rigid column of the present invention includes a first component, a second component and several inner partitions 3. The first component is spliced ​​to the second component, and the first component and the second component are vertically fixed by welding.

[0125] The inner partition 3 is vertically welded between the first component and the second component.

[0126] Both the first and second components use the first I-beam 9 to meet the splicing and welding requirements of stiffened columns of different shapes.

[0127] The first I-beam 9 has an I-shaped structure with equal lengths on both side flanges 4.

[0128] The above structural design not only improves the overall stability and reliability of the stiffening column, but also allows the welding robot to extend the welding torch into the welding area, improving welding efficiency, facilitating splicing and welding, adapting to industrial production, and greatly improving production efficiency.

[0129] like Figure 24 and Figure 26 The diagram illustrates the splicing and welding method for the stiffening column of the present invention, comprising the following steps:

[0130] S1. Material cutting: Select a suitable steel plate shape, including the first I-beam 9;

[0131] S2. Connect the first I-beam 9 to the inclined base, and assemble and position the other first I-beam 9. Then, straighten the two first I-beams 9 once by flame straightening or mechanical straightening. By flipping the pre-assembled steel components, the weld seam is not blocked by the outer flange, thus improving the welding quality.

[0132] S3. The scanning area of ​​the two first I-beams 9 is scanned by the scanner of the welding robot, and the weld seam of the two first I-beams 9 is welded to obtain the stiffened column.

[0133] S4. Reassemble and position the stiffening columns that are not welded properly. Once the stiffening columns that meet the dimensions are assembled, perform secondary straightening through flame straightening or mechanical straightening.

[0134] S5. After straightening, the stiffening column is inspected. The stiffening column that fails the inspection is straightened a second time by flame straightening or mechanical straightening. The stiffening column that passes the inspection is the finished product.

[0135] This splicing and welding process makes the quality controllable during processing and improves the yield rate.

[0136] like Figures 22 to 23 As shown, the rigid column of the present invention includes a first component, a second component and several inner partitions 3. The first component is spliced ​​to the second component, and the first component and the second component are vertically fixed by welding.

[0137] The inner partition 3 is vertically welded between the first component and the second component.

[0138] The first component uses the first I-beam 9, and the second component uses the second I-beam 12, to meet the splicing and welding requirements of stiffened columns of different shapes.

[0139] The first I-beam 9 has an I-shaped structure with equal lengths of the two side flanges 4, while the second I-beam 12 has an I-shaped structure with the outer flange 4 having a shorter length than the inner flange 4.

[0140] The above structure makes it easier for the robot's welding torch to weld along the weld seam, and the outer flange plate 4 will not collide with the welding torch. The outer flange of the second I-beam 12 is shorter than the flange of the first I-beam 9, which gives the welding torch a larger swing radius, torch entry path and torch exit path.

[0141] The above structural design not only improves the overall stability and reliability of the stiffening column, but also allows the welding robot to extend the welding torch into the welding area, improving welding efficiency, facilitating splicing and welding, adapting to industrial production, and greatly improving production efficiency.

[0142] like Figure 25 and Figure 26 The diagram illustrates the splicing and welding method for the stiffening column of the present invention, comprising the following steps:

[0143] S1. Material cutting: Select a suitable steel plate shape, which includes the first I-beam 9 and the second I-beam 12.

[0144] S2. The first I-beam 9 and the second I-beam 12 are horizontally assembled and positioned, and the first I-beam 9 and the second I-beam 12 are straightened once by flame straightening or mechanical straightening.

[0145] S3. The scanning area between the first I-beam 9 and the second I-beam 12 is scanned by the scanner of the welding robot, and the stiffened column is obtained by welding along the weld between the first I-beam 9 and the second I-beam 12.

[0146] S4. Reassemble and position the stiffening columns that are not welded properly. Once the stiffening columns that meet the dimensions are assembled, perform secondary straightening through flame straightening or mechanical straightening.

[0147] S5. After straightening, the stiffening column is inspected. The stiffening column that fails the inspection is straightened a second time by flame straightening or mechanical straightening. The stiffening column that passes the inspection is the finished product.

[0148] This splicing and welding process makes the quality controllable during processing and improves the yield rate.

[0149] Example 5

[0150] The rigid column of this invention includes a first component and a second component. The first component is spliced ​​onto the second component, and the connection between the first component and the second component is achieved by welding. The first component and the second component may not be perpendicular. Furthermore, an inner partition may not be installed between the first component and the second component.

[0151] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to achieve substantially the same technical effect are all covered within the protection scope of the present invention.
