Description

Technical Field

[0001] The invention relates to a rigid column and a splicing and welding method thereof. Background Art

[0002] The rigid cross column is a key structural form in modern construction. Its basic construction consists of steel sections encased in concrete. This structure offers numerous advantages, including high seismic resistance. Its application is particularly important in high-rise buildings, large structures, and earthquake-prone areas. By encasing the steel sections in concrete, the rigid cross column not only increases its overall load-bearing capacity but also effectively reduces its cross-sectional dimensions, thereby saving space and lowering construction costs.

[0003] In the prior art, a rigid cross column is assembled and welded by combining an H-shaped steel and two T-shaped steel structures. Since the assembled T-shaped structure has a partition inside and the steel structure is provided with a relatively wide flange, the above-mentioned structure blocks the welding robot from extending the welding gun into the welding area, and manual welding is the only option, resulting in low welding efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a technical solution for a rigid column and its splicing and welding method to address the deficiencies in the prior art. This solution not only improves the overall stability and reliability of the rigid column, but also enables the welding robot to extend the welding gun into the welding area, thereby improving welding efficiency, facilitating splicing and welding, adapting to industrial production, and greatly improving production efficiency. The splicing and welding process makes the quality controllable during the processing process and improves the yield rate.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] The rigid column is characterized by comprising:

[0007] at least one first component;

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

[0009] Through the design of the above structure, not only the overall stability and reliability of the stiffening column can be improved, but also the welding robot can extend the welding gun into the welding area, thereby improving welding efficiency, facilitating splicing and welding, adapting to industrial production, and greatly improving production efficiency.

[0010] Furthermore, the first component and the second component include web assemblies and / or I-beams, meeting the splicing and welding requirements of stiffening columns of different shapes.

[0011] Furthermore, the web assembly includes an integral web connected to a flange plate or two single webs of matching sizes, which can meet the needs of splicing and welding rigid columns in different occasions and improve the flexibility of splicing and welding rigid columns.

[0012] Furthermore, both the integral web and the I-beam are provided with slots, the length of which is 1 / 2 of the length of the integral web or the I-beam, which is beneficial to improving the overall connection strength of the rigid column and making the entire structure more stable and reliable.

[0013] Furthermore, the flange plate is provided with a mounting opening, and the mounting opening, the inner edge of the slot and one side of the single web are each provided with at least one groove, the inclination angle of the groove is 25° to 45°, and the welding gun can deposit metal along the groove during welding to improve the welding quality of the weld. A smaller welding angle requires less metal to be deposited, which reduces welding and heat input, thereby reducing deformation caused by welding. The angle of the groove is adjusted according to the welding performance of the welding robot.

[0014] Furthermore, when welding the single web, the single web is assembled obliquely with respect to the welding surface, which is beneficial to reducing the cooling shrinkage deformation during welding and reducing the subsequent correction work.

[0015] Furthermore, when the flange plates are connected by plug welding, a steel lining strip is provided on the side away from the groove to prevent welding through and burning through.

[0016] Furthermore, the I-beam is in an I-shaped structure with flange plates on both sides of equal length or in an I-shaped structure with an outer flange plate of shorter length than an inner flange plate.

[0017] Furthermore, it also includes a plurality of inner baffles, which are welded between the first component and the second component.

[0018] The method for splicing and welding the rigid columns is characterized by comprising the following steps:

[0019] S1. Cutting and selecting a suitable steel plate shape, which includes a first component and a second component;

[0020] S2. Assemble and position the first component and the second component, and perform a correction on the first component and the second component by flame correction or mechanical correction;

[0021] S3, scanning a scanning area between the first component and the second component by a scanner of the welding robot, and welding along the weld between the first component and the second component to obtain a stiffening column;

[0022] S4. Reassemble and reposition the rigid columns that failed welding, complete the assembly of the rigid columns with qualified dimensions, and perform secondary correction through flame correction or mechanical correction;

[0023] S5. After correction, the rigid columns are inspected. The rigid columns that fail the inspection are further corrected by flame correction or mechanical correction. The rigid columns that pass the inspection are finished products.

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

[0025] The present invention has the following beneficial effects due to the adoption of the above technical solution:

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

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0058] It should be noted that the terms "first," "second," and so on in the description and claims of the present invention and the accompanying drawings are used to distinguish similar items and are not necessarily used to describe a specific order or precedence. Furthermore, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions.

[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 a plurality of inner partitions 3. The first component is spliced ​​to the second component, and the vertical fixation of the first component and the second component is achieved by welding.

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

[0062] The first component and the second component both include web assemblies, which meet the splicing and welding requirements of stiff columns of different shapes.

[0063] The web assembly comprises an integral web connected to a flange plate 4, which satisfies the splicing and welding of rigid columns in different occasions and improves the flexibility during the splicing and welding of rigid columns.

[0064] The integral web in this embodiment includes a first web 1 and a second web 2, and the first web 1 and the second web 2 are both 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 1 / 2 of the length of the first web 1, and the length of the second slot 201 is 1 / 2 of the length of the second web 2, which is beneficial to improving the overall connection strength of the stiffening column and making the entire structure more stable and reliable.

[0065] The flange plate 4 is provided with an installation opening 401, and the installation opening 401, the inner edge of the slot and one side of the single web are all provided with grooves. The first groove 402 is on the installation opening 401, and the inner edge of the slot and one side of the single web are the second groove 8. During welding, the welding gun can deposit metal along the groove to improve the welding quality of the weld.

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

[0067] When the flange plate 4 is connected by plug welding, a steel lining strip 5 is provided on the side away from the groove to prevent welding through and burning through.

[0068] Through the design of the above structure, not only the overall stability and reliability of the stiffening column can be improved, but also the welding robot can extend the welding gun into the welding area, thereby improving welding efficiency, facilitating splicing and welding, adapting to industrial production, and greatly improving production efficiency.

[0073] When welding the first web 1 and the second web 2, the first weld 6 is welded first, and then the second weld 7. The first weld 6 and the second weld 7 are welded in the order of ① to ⑤. After the first weld 6 is cooled, the deformation degree of the welding material is observed. If it exceeds the allowable deformation value, flame correction is performed. The specific flame temperature is selected from 600 to 800°C, preferably 700°C. Flame correction is performed along the length direction of the weld to eliminate the residual stress of the weld.

[0074] After the flame correction is completed and cooled, the second weld 7 is welded again. The welding sequence is base welding-filling welding-cap welding. The cap welding adopts robot automatic welding, and submerged arc welding can also be selected. When submerged arc welding is selected, the flux needs to be dried. Similarly, if flame correction is required, the welding process as described above is used to eliminate welding stress.

[0075] S4. Reassemble and reposition the rigid columns that failed welding, complete the assembly of the rigid columns with qualified dimensions, and perform secondary correction through flame correction or mechanical correction;

[0076] After the first web 1 and the second web 2 are welded, the inner partition 3 is assembled first. After the positioning of the inner partition 3 is completed, it is welded and corrected to keep the inner partition 3 flush, and 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 groove 402. When assembling, the flange plate 4 at the corresponding position is placed on the inner partition 3, and then welded. The flange plate 4 adopts plug welding. In order to make the welding beautiful and adapt to industrial production, a steel lining strip 5 is used on the side of the second web 2 located at the second groove 8 to prevent dripping during welding. When the flange plate 4 is welded, Figure 8 As shown, first weld ①~④ on one side, then weld ④~⑧ on the other side, and finally weld the cover ⑨.

[0078] S5. After correction, the rigid columns are inspected. The rigid columns that fail the inspection are further corrected by flame correction or mechanical correction. The rigid columns that pass the inspection are finished products.

[0079] This splicing welding process makes the quality controllable during the 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 a plurality of inner partitions 3. The first component is spliced ​​to the second component, and the vertical fixation of the first component and the second component is achieved by welding.

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

[0084] The web assembly comprises an integral web connected to a flange plate 4, which satisfies the splicing and welding of rigid columns in different occasions and improves the flexibility during the splicing and welding of rigid columns.

The first groove 402 is on the installation opening 401, and the inner edge of the slot and one side of the single web are the second groove 8. During welding, the welding gun can deposit metal along the groove to improve the welding quality of the weld.

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

[0088] When the flange plate 4 is connected by plug welding, a steel lining strip 5 is provided on the side away from the groove to prevent welding through and burning through.

[0089] Through the design of the above structure, not only the overall stability and reliability of the stiffening column can be improved, but also the welding robot can extend the welding gun into the welding area, thereby improving welding efficiency, facilitating splicing and welding, adapting to industrial production, and greatly improving production efficiency.

[0090] like Figure 26 As shown, the splicing and welding method of the stiffening column of the present invention includes the following steps:

[0091] S1, cutting and blanking, selecting a suitable steel plate shape, the steel plate shape including the first web 1 and the first I-beam 9;

[0092] S2. Assemble and position the first web 1 and the first I-beam 9, and perform a primary correction on the first web 1 and the first I-beam 9 by flame correction or mechanical correction;

[0094] When welding the first web 1 and the first I-beam 9, the first weld 6 is welded first, and then the second weld 7. The first weld 6 and the second weld 7 are welded in the order of ① to ⑤. After the first weld 6 is cooled, the deformation degree of the welding material is observed. If it exceeds the allowable deformation value, flame correction is performed. The specific flame temperature is selected from 600 to 800°C, preferably 700°C. Flame correction is performed along the length direction of the weld to eliminate the residual stress of the weld.

[0095] After the flame correction is completed and cooled, the second weld 7 is welded again. The welding sequence is base welding-filling welding-cap welding. The cap welding adopts robot automatic welding, and submerged arc welding can also be selected. When submerged arc welding is selected, the flux needs to be dried. Similarly, if flame correction is required, the welding process as described above is used to eliminate welding stress.

[0096] S4. Reassemble and reposition the rigid columns that failed welding, complete the assembly of the rigid columns with qualified dimensions, and perform secondary correction through flame correction or mechanical correction;

[0097] After the first web 1 and the first I-beam 9 are welded, the inner partition 3 is assembled first. After the positioning of the inner partition 3 is completed, it is welded and corrected to keep the inner partition 3 flush. Then the flange plate 4 is assembled. After welding and flame correction, the size inspection and size correction are carried out.

[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 groove 402. When assembling, the flange plate 4 at the corresponding position is placed on the inner partition 3, and then welded. The flange plate 4 adopts plug welding. In order to make the welding beautiful and adapt to industrial production, a steel lining strip 5 is used on the side of the first web 1 located at the second groove 8 to prevent dripping during welding. When the flange plate 4 is welded, Figure 8 As shown, first weld ①~④ on one side, then weld ④~⑧ on the other side, and finally weld the cover ⑨.

[0099] S5. After correction, the rigid columns are inspected. The rigid columns that fail the inspection are further corrected by flame correction or mechanical correction. The rigid columns that pass the inspection are finished products.

[0100] This splicing welding process makes the quality controllable during the 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 a plurality of inner partitions 3. The first component is spliced ​​to the second component, and the vertical fixation of the first component and the second component is achieved by welding.

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

[0104] Through the design of the above structure, not only the overall stability and reliability of the stiffening column can be improved, but also the welding robot can extend the welding gun into the welding area, thereby 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 is an I-shaped structure with flange plates 4 of equal length on both sides. The second component includes a web assembly to meet the splicing and welding requirements of rigid columns of different shapes.

[0106] Alternatively, the first component includes a wider third web 10 and two narrower fourth webs 11 , the third web 10 is pre-connected with two flange plates 4 , and then the two fourth webs 11 are connected to both sides of the third web 10 .

[0107] The web assembly comprises two single webs of matching sizes connected to flange plates 4, which meet the requirements of splicing and welding of rigid columns in different occasions and improve the flexibility of splicing and welding of rigid columns.

[0108] The single web in this embodiment adopts the third web 10 and the fourth web 11 .

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

[0110] When welding single webs, assembling them diagonally relative to the welding surface helps reduce shrinkage and deformation during welding and reduces subsequent correction work. The inclination angle of the single web is β, which is preferably 5° and can be selected according to actual working conditions.

[0111] When the flange plate 4 is connected by plug welding, a steel lining strip 5 is provided on the side away from the groove to prevent welding through and burning through.

[0112] like Figure 26 As shown, the splicing and welding method of the stiffening column of the present invention includes the following steps:

[0115] S3, scanning the scanning area between the first I-beam 9, the third web 10 and the fourth web 11 by the scanner of the welding robot, and welding along the weld between the first I-beam 9, the third web 10 and the fourth web 11 to obtain a stiff column;

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

[0117] After the flame correction is completed and cooled, the second weld 7 is welded again. The welding sequence is base welding-filling welding-cap welding. The cap welding adopts robot automatic welding, and submerged arc welding can also be selected. When submerged arc welding is selected, the flux needs to be dried. Similarly, if flame correction is required, the welding process as described above is used to eliminate welding stress.

[0118] S4. Reassemble and reposition the rigid columns that failed welding, complete the assembly of the rigid columns with qualified dimensions, and perform secondary correction through flame correction or mechanical correction;

[0119] After the first I-beam 9 , the third web 10 and the fourth web 11 are welded, the inner partition 3 is assembled first. After the positioning of the inner partition 3 is completed, it is welded and corrected to keep the inner partition 3 flush, and 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 groove 402. When assembling, the flange plate 4 at the corresponding position is placed on the inner partition 3, and then welded. The flange plate 4 adopts plug welding. In order to make the welding beautiful and adapt to industrial production, a steel lining strip 5 is used on the side of the third web 10 and the fourth web 11 located at the second groove 8 to prevent dripping during welding. When the flange plate 4 is welded, Figure 8 As shown, first weld ①~④ on one side, then weld ④~⑧ on the other side, and finally weld the cover ⑨.

[0121] S5. After correction, the rigid columns are inspected. The rigid columns that fail the inspection are further corrected by flame correction or mechanical correction. The rigid columns that pass the inspection are finished products.

[0122] This splicing welding process makes the quality controllable during the 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 a plurality of inner partitions 3. The first component is spliced ​​to the second component, and the vertical fixation of the first component and the second component is achieved by welding.

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

[0126] The first assembly and the second assembly both use the first I-beam 9 to meet the splicing and welding requirements of rigid columns of different shapes.

[0127] The first I-beam 9 is in an I-shaped structure with flange plates 4 on both sides of equal length.

[0128] Through the design of the above structure, not only the overall stability and reliability of the stiffening column can be improved, but also the welding robot can extend the welding gun into the welding area, thereby improving welding efficiency, facilitating splicing and welding, adapting to industrial production, and greatly improving production efficiency.

[0129] like Figure 24 and Figure 26 As shown, the splicing and welding method of the stiffening column of the present invention includes the following steps:

[0130] S1, cutting and blanking, selecting a suitable steel plate shape, the steel plate shape including the first I-beam 9;

[0131] S2. Connect the first I-beam 9 to the inclined base, assemble and position another first I-beam 9, and correct the two first I-beams 9 once by flame correction or mechanical correction; by turning over the pre-assembled steel components, the weld seam will not be blocked by the outer flange, thereby improving the welding quality.

[0132] S3, scanning the scanning area of ​​the two first I-beams 9 by the scanner of the welding robot, and welding along the weld seams of the two first I-beams 9 to obtain a stiffening column;

[0133] S4. Reassemble and reposition the rigid columns that failed welding, complete the assembly of the rigid columns with qualified dimensions, and perform secondary correction through flame correction or mechanical correction;

[0134] S5. After correction, the rigid columns are inspected. The rigid columns that fail the inspection are further corrected by flame correction or mechanical correction. The rigid columns that pass the inspection are finished products.

[0135] This splicing welding process makes the quality controllable during the 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 a plurality of inner partitions 3. The first component is spliced ​​to the second component, and the vertical fixation of the first component and the second component is achieved by welding.

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

[0138] The first assembly adopts the first I-beam 9 and the second assembly adopts the second I-beam 12, which meet the splicing and welding requirements of rigid columns of different shapes.

[0139] The first I-beam 9 is in an I-shaped structure with flange plates 4 on both sides of equal length, and the second I-beam 12 is in an I-shaped structure with an outer flange plate 4 of less length than an inner flange plate 4 .

[0140] The above structure can make it easier for the robot's welding gun to weld along the weld seam, and the external flange plate 4 will not collide with the welding gun. The external flange of the second I-beam 12 is shorter than the flange of the first I-beam 9, so that the welding gun has a larger swing radius, gun advance path and gun retreat path.

[0141] Through the design of the above structure, not only the overall stability and reliability of the stiffening column can be improved, but also the welding robot can extend the welding gun into the welding area, thereby improving welding efficiency, facilitating splicing and welding, adapting to industrial production, and greatly improving production efficiency.

[0142] like Figure 25 and Figure 26 As shown in FIG, the splicing and welding method of the stiffening column of the present invention comprises the following steps:

[0143] S1, cutting and blanking, selecting a suitable steel plate shape, the steel plate shape includes a first I-beam 9 and a second I-beam 12;

[0144] S2, assembling and positioning the first I-beam 9 and the second I-beam 12 horizontally, and correcting the first I-beam 9 and the second I-beam 12 once by flame correction or mechanical correction;

[0145] S3, scanning the scanning area between the first I-beam 9 and the second I-beam 12 by the scanner of the welding robot, and welding along the weld between the first I-beam 9 and the second I-beam 12 to obtain a stiffening column;

[0146] S4. Reassemble and reposition the rigid columns that failed welding, complete the assembly of the rigid columns with qualified dimensions, and perform secondary correction through flame correction or mechanical correction;

[0147] S5. After correction, the rigid columns are inspected. The rigid columns that fail the inspection are further corrected by flame correction or mechanical correction. The rigid columns that pass the inspection are finished products.

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