Description

Technical Field

[0001] This invention relates to the field of steel structure technology, and in particular to a method for manufacturing a multi-partition box-type node and the multi-partition box-type node itself. Background Technology

[0002] With the booming development of the construction industry across the country, super high-rise buildings are emerging in various regions. These buildings mainly adopt core tube steel frame structures, which can make full use of the excellent plasticity and toughness of steel to meet various spatial shapes and functional requirements. Some of these steel frame structures adopt unique extended shapes, mainly composed of box-shaped inclined columns and circular tube hanging columns. Irregular box-shaped structures are used as nodes to connect the inclined columns and hanging columns, and multiple stiffening plates are set inside the box-shaped nodes for reinforcement, forming a stable support system. This box-type node typically has a large vertical partition inside, dividing the whole into two symmetrical partition areas. Each partition area has a horizontal partition for stiffening the corresponding external beam, an oblique partition for stiffening the corresponding inclined column, and a small vertical partition for stiffening the corresponding hanging column. Multiple partitions divide each partition area into multiple sealed cavities, and the orientation of each partition inside is different. The bottom plate seals the lower end of the box-type node. Its internal operating space is small, the assembly is difficult, and the welding requirements are high. Some partitions can only be fixed by clamping, which makes it difficult to meet the requirement of welding all partitions on four sides. Therefore, the choice of assembly process and welding method is the key and difficult point in the manufacture of this box-type node. Summary of the Invention

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a method for manufacturing multi-partition box-type nodes, which optimizes the welding sequence and structural design, enabling the welding of all four sides of all partitions in the partition area, thus facilitating the manufacturing of multi-partition box-type nodes.

[0004] The present invention also proposes a method for manufacturing a multi-partition box-type node using this method.

[0005] According to a first aspect embodiment of the present invention, the manufacturing method of the multi-partition box-shaped node includes a first main body plate, a second main body plate, a first vertical partition, a horizontal partition, an oblique partition, a second vertical partition, a third main body plate, a fourth main body plate, a bottom plate, and a top plate. The manufacturing method includes the following steps:

[0006] S1: The first main plate and the second main plate are arranged vertically and assembled with the first vertical partition to form an "H" shape. The first vertical partition is welded to the first main plate and the second main plate respectively, so that the left and right sides of the first vertical partition form two symmetrical partition areas.

[0007] S2: The base plate is located below the first main plate and the first vertical partition and is fixed by spot welding. The lower edge of the second main plate is spaced apart from the base plate, so that the second main plate and the base plate form an operating port that communicates with the partition area. The transverse partition is located above the partition area and is welded to the first main plate, the second main plate and the first vertical partition respectively. The oblique partition is located below the partition area and is set at an angle. The oblique partition is welded to the second main plate, the first vertical partition and the base plate respectively.

[0008] S3: There are two third main body plates located on the left and right sides of the first vertical partition. The two third main body plates are symmetrical with respect to the first vertical partition. The third main body plates are welded to the first main body plate and the second main body plate respectively. The bottom plate is welded to the first main body plate and the third main body plate respectively. They are combined to form a box-shaped main body with an opening on the upper side. The top plate is placed on the upper opening of the box-shaped main body. The top plate is welded to the first main body plate, the second main body plate and the third main body plate respectively.

[0009] S4: Insert the oblique partition into the partition area from the operating port to weld the oblique partition to the third main body plate, completing the welding of the oblique partition on all four sides. Insert the second vertical partition into the partition area from the operating port. Weld the second vertical partition to the first vertical partition, the oblique partition, the third main body plate and the bottom plate respectively, completing the welding of the second vertical partition on all four sides.

[0010] S5: The fourth main body plate is placed over the operating port and fixed by spot welding. The fourth main body plate is welded to the second main body plate, the third main body plate and the bottom plate respectively.

[0011] S6: The transverse partition is welded to the third main plate by electroslag welding to complete the welding of the four sides of the transverse partition.

[0012] The manufacturing method of the multi-partition box-type node according to the embodiments of the present invention has at least the following beneficial effects: The manufacturing method optimizes the welding sequence and structural design of the multi-partition box-type node. For the transverse partition, three-sided welding is first adopted. After the third main plate is welded and assembled, the welding between the transverse partition and the third main plate is completed by electroslag welding, thus completing the four-sided welding of the transverse partition. For the oblique partition and the second vertical partition, the oblique partition is first welded on three sides. Through the operating hole formed between the second main plate and the bottom plate, the welding between the oblique partition and the third main plate can be operated to complete the four-sided welding of the oblique partition. Then, the second vertical partition is placed into the partition area through the operating hole to complete the four-sided welding of the second vertical partition. Thus, all partitions in the partition area meet the requirements of four-sided welding. By adjusting the welding sequence, the problems of weld conflict and inability to weld between opposite partitions are solved, ensuring the welding quality of the weld and facilitating the manufacturing of the multi-partition box-type node.

[0013] According to some embodiments of the present invention, in step S1, before the first main body plate, the second main body plate and the first vertical partition plate are assembled into an "H" shape, they are first marked and positioned, and the weld seams between the first vertical partition plate and the first main body plate and the second main body plate are filled and welded, and the weld seams are cleaned on the outside.

[0015] According to some embodiments of the present invention, in step S2, after the welding of the transverse partition is completed and the weld seam of the transverse partition is inspected, the oblique partition is assembled. The oblique partition is first fixed by spot welding and then welded to the second main body plate, the first vertical partition and the bottom plate respectively. Subsequently, the unassembled second vertical partition is marked and positioned on the oblique partition and the bottom plate.

[0016] According to some embodiments of the present invention, in step S3, the weld between the first main plate, the second main plate and the third main plate is first pre-welded by root pass welding, the bottom plate is welded to the first main plate and the third main plate by backing weld, and the top plate is welded to the first main plate, the second main plate and the third main plate by backing weld, and then the weld between the first main plate, the second main plate and the third main plate is completed, and all welds are full penetration.

[0017] According to some embodiments of the present invention, in step S4, the welding of the four sides of the second vertical partition is carried out by backing welding and all welds are fully penetrated.

[0018] According to some embodiments of the present invention, in step S5, the fourth main plate is welded to the second main plate, the third main plate and the bottom plate by a backing weld, and the welds are all full penetration welds.

[0019] According to some embodiments of the present invention, in step S5, two fourth main body plates are provided and spaced apart in the left and right direction, so that a strip groove is formed between the first vertical partition and the two fourth main body plates, and the groove is plugged and welded to complete the welding between the first vertical partition and the two fourth main body plates.

[0020] According to some embodiments of the present invention, the welding of the first main body plate, the second main body plate, the third main body plate, the fourth main body plate and the first vertical partition plate all adopt the measures of preheating before welding and heat preservation after welding.

[0021] According to some embodiments of the present invention, the multi-partition box-type node includes brackets and angle steel. The structure obtained after completing step S6 is inspected and corrected, and then the brackets and angle steel are assembled and welded at preset positions.

[0023] The multi-partition box-type node according to the embodiments of the present invention has at least the following beneficial effects: by adopting the above-mentioned manufacturing method of the multi-partition box-type node, the welding sequence and structural design are optimized, so that all partitions in the partition area can meet the requirements of four-sided welding. By adjusting the welding sequence, the problems of weld conflict and inability to weld between partitions in opposite directions are solved, ensuring the welding quality of the welds, and making the resulting multi-partition box-type node structure stable, reliable and easy to use.

[0039] S1: The first main plate 110 and the second main plate 120 are arranged vertically and assembled with the first vertical partition 210 to form an "H" shape. The first vertical partition 210 is welded to the first main plate 110 and the second main plate 120 respectively, so that the left and right sides of the first vertical partition 210 form two symmetrical partition areas 101.

[0040] S2: The base plate 150 is located on the lower side of the first main plate 110 and the first vertical partition 210 and is fixed by spot welding. The lower edge of the second main plate 120 is spaced apart from the base plate 150, so that the second main plate 120 and the base plate 150 form an operation port 102 that communicates with the partition area 101. The transverse partition 220 is located on the upper side of the partition area 101 and is welded to the first main plate 110, the second main plate 120 and the first vertical partition 210 respectively. The oblique partition 230 is located on the lower side of the partition area 101 and is inclined. The oblique partition 230 is welded to the second main plate 120, the first vertical partition 210 and the base plate 150 respectively.

[0041] S3: Two third main body plates 130 are provided and located on the left and right sides of the first vertical partition 210 respectively. The two third main body plates 130 are symmetrical with respect to the first vertical partition 210. The third main body plates 130 are welded to the first main body plate 110 and the second main body plate 120 respectively. The bottom plate 150 is welded to the first main body plate 110 and the third main body plate 130 respectively, and the combination forms a box-shaped main body 100 with an upper opening. The top plate 160 is placed on the upper opening of the box-shaped main body 100. The top plate 160 is welded to the first main body plate 110, the second main body plate 120 and the third main body plate 130 respectively.

[0042] S4: Insert the oblique partition 230 into the partition area 101 from the operation port 102 to weld it to the third main body plate 130, completing the welding of the oblique partition 230 on all four sides. Insert the second vertical partition 240 into the partition area 101 from the operation port 102. Weld the second vertical partition 240 to the first vertical partition 210, the oblique partition 230, the third main body plate 130 and the bottom plate 150 respectively, completing the welding of the second vertical partition 240 on all four sides.

[0043] S5: The fourth main plate 140 is placed over the operation port 102 and fixed by spot welding. The fourth main plate 140 is welded to the second main plate 120, the third main plate 130 and the base plate 150 respectively.

[0044] S6: The transverse partition 220 and the third main plate 130 are welded together by electroslag welding to complete the welding of the four sides of the transverse partition 220.

[0045] Understandably, such as Figure 4and Figure 5 As shown, the multi-partition box-type node includes a first main plate 110, a second main plate 120, a first vertical partition 210, a horizontal partition 220, an oblique partition 230, a second vertical partition 240, a third main plate 130, a fourth main plate 140, a bottom plate 150, and a top plate 160. Before step S1, CNC cutting and blanking can be performed according to the plate dimensions, and beveling, drilling, and electroslag welding hole opening of the plates can be completed as required. Specifically, in this embodiment, the first main plate 110 and the second main plate 120... The first vertical partition 210, the horizontal partition 220, the diagonal partition 230, the second vertical partition 240, the third main plate 130, the fourth main plate 140, the bottom plate 150, and the top plate 160 all need to have corresponding bevels. Holes are drilled on the top plate 160 for ventilation. Holes for electroslag welding (not shown in the figure) are made on the first main plate 110 and the second main plate 120 corresponding to the horizontal partition 220. Then, according to the overall dimensions of the components in the drawings, the tooling jig for the assembly welding operation of the components is designed and arranged.

[0046] When performing step S1, refer to Figure 4 and Figure 5 The first main plate 110 and the second main plate 120 are arranged at a distance from front to back. The first vertical partition 210 is arranged between the first main plate 110 and the second main plate 120 and parallel to the front-back direction, so that the first main plate 110, the second main plate 120 and the first vertical partition 210 are assembled into an "H" shape. Then, the welding between the first vertical partition 210 and the first main plate 110 and the second main plate 120 is completed, so that two symmetrical partition areas 101 are formed on the left and right sides of the first vertical partition 210.

[0047] When performing step S2, refer to Figure 4 and Figure 5 The base plate 150 is located below the first main body plate 110 and the first vertical partition 210. When assembling the second main body plate 120 in step S1, the lower edge of the second main body plate 120 is higher than the lower edges of the first main body plate 110 and the first vertical partition 210. This ensures that after the base plate 150 is installed in step S2, there is a gap between the lower edge of the second main body plate 120 and the base plate 150, forming an operating opening 102 that communicates with the partition area 101. The base plate 150 is initially fixed by spot welding. To correct any problems that may arise later; the horizontal partition 220 is placed on the upper side of the partition area 101, and the horizontal partition 220 is welded to the first main plate 110, the second main plate 120 and the first vertical partition 210 respectively, completing the three-sided welding of the horizontal partition 220; the oblique partition 230 is placed on the lower side of the partition area 101 and is set at an angle, and the oblique partition 230 is welded to the second main plate 120, the first vertical partition 210 and the bottom plate 150 respectively, completing the three-sided welding of the oblique partition 230.

[0048] When performing step S3, refer to Figure 3 , Figure 4 and Figure 5 Two third main body plates 130 are respectively placed on the left and right sides of the first vertical partition 210. The two third main body plates 130 are symmetrical with respect to the first vertical partition 210. The first main body plate 110, the second main body plate 120 and the third main body plate 130 form a box shape. Each third main body plate 130 is welded to the first main body plate 110 and the second main body plate 120 respectively. Then, the bottom plate 150 is welded and fixed to the first main body plate 110 and the third main body plate 130 to form a box-shaped main body 100 with an upper opening. Then, the top plate 160 is placed on the upper opening of the box-shaped main body 100. The four edges of the top plate 160 are welded to the first main body plate 110, the second main body plate 120 and the third main body plate 130 respectively.

[0049] When performing step S4, refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 The weld between the inclined partition 230 and the third main plate 130 is extended into the partition area 101 from the operation port 102, thereby fixing the inclined partition 230 on all four sides. After the inclined partition 230 is welded, the second vertical partition 240 is inserted into the partition area 101 from the operation port 102. The four edges of the second vertical partition 240 are welded to the first vertical partition 210, the inclined partition 230, the third main plate 130 and the bottom plate 150, respectively, to complete the welding of the four sides of the second vertical partition 240.

[0050] When performing step S5, refer to Figure 2 , Figure 4 and Figure 5 The fourth main plate 140 is placed over the operating port 102. The fourth main plate 140 is first fixed by spot welding so that the fourth main plate 140 is aligned with the second main plate 120. After confirming the position, the fourth main plate 140 is welded to the second main plate 120, the third main plate 130 and the base plate 150 respectively to close the operating port 102.

[0051] When performing step S6, refer to Figure 3 , Figure 4 and Figure 5 The transverse partition 220 and the third main plate 130 are welded together by electroslag welding to complete the welding of the four sides of the transverse partition 220. After the welding is completed, the weld seam of the electroslag welding can be ground to make the appearance smooth and beautiful.

[0052] This manufacturing method optimizes the welding sequence, structural design, and welding deformation control of multi-partition box-type nodes. For the transverse partition 220, three-sided welding is first used. After the third main plate 130 is welded and assembled, electroslag welding is used to complete the welding between the transverse partition 220 and the third main plate 130, thus completing the four-sided welding of the transverse partition 220. For the oblique partition 230 and the second vertical partition 240, the oblique partition 230 is first welded on three sides. Through the operating hole formed between the second main plate 120 and the bottom plate 150, the oblique partition 230 can be operated to... Welding between the third main plates 130 completes the four-sided welding of the oblique partition 230. Then, the second vertical partition 240 is inserted into the partition area 101 through the operating hole, completing the four-sided welding of the second vertical partition 240. This ensures that all partitions in the partition area 101 meet the requirement of four-sided welding. By adjusting the welding sequence, the problems of weld conflict and inability to weld between partitions in different directions are solved, ensuring the welding quality of the welds and facilitating the fabrication of multi-partition box-type nodes. The fabrication method provided by this invention completes the assembly and welding of irregular multi-partition box-type nodes, broadening its application in the field of steel structures.

[0053] Furthermore, in step S1, before the first main body plate 110, the second main body plate 120 and the first vertical partition plate 210 are assembled into an "H" shape, they are first marked and positioned, and the weld seams between the first vertical partition plate 210 and the first main body plate 110 and the second main body plate 120 are filled and welded, and the weld seams are cleaned on the outside.

[0054] Understandably, marking and positioning facilitates the assembly of the first main plate 110, the second main plate 120, and the first vertical partition 210 into the required "H" shape. The root-cleaning welding method, involving internal filling welding and external root cleaning, helps ensure penetration at the weld root and achieves better weld quality. In practical applications, the marking and positioning between the first main plate 110, the second main plate 120, and the first vertical partition 210 can be determined according to actual usage needs, and the welding method used can also be backing welding, etc.

[0055] Furthermore, in step S2, each partition area 101 is provided with multiple horizontal partitions 220. The horizontal partitions 220 in the same partition area 101 are spaced apart in the vertical direction, and the horizontal partitions 220 in two partition areas 101 are symmetrical with respect to the first vertical partition 210.

[0056] Understandably, such as Figure 4 and Figure 5As shown, each partition area 101 is provided with three transverse partitions 220. The three transverse partitions 220 in the same partition area 101 are spaced apart in the vertical direction. Through multiple transverse partitions 220, a good stiffening effect can be achieved for the corresponding outer beam. The transverse partitions 220 in the left and right partition areas 101 are symmetrical with respect to the first vertical partition 210. During step S6, the transverse partitions 220 on the left and right sides are welded by double-sided symmetrical electroslag welding, which helps to reduce the overall welding deformation of the box-type structure and facilitates its use. In practical applications, the number of transverse partitions 220 in each partition area 101 can also be two, four or more, and the specific number can be set according to the actual needs of use.

[0057] Further, in step S2, after the welding of the transverse partition 220 is completed and the weld seam of the transverse partition 220 is inspected, the oblique partition 230 is assembled. The oblique partition 230 is first fixed by spot welding and then welded to the second main body plate 120, the first vertical partition 210 and the bottom plate 150 respectively. Then, the unassembled second vertical partition 240 is marked and positioned on the oblique partition 230 and the bottom plate 150.

[0058] Understandably, such as Figure 4 and Figure 5 As shown, after the base plate 150 is spot-welded in step S2, the three sides of the transverse partition 220 are welded first, so that the transverse partition 220 is welded and fixed to the first main plate 110, the second main plate 120 and the first vertical partition 210 respectively. Then, the weld of the transverse partition 220 is inspected for weld flaws. After the inspection is qualified, the oblique partition 230 is assembled and welded. The oblique partition 230 is initially fixed by spot welding. After the assembly position is determined, the three sides of the oblique partition 230 are then welded. The inclined partition 230 is welded and fixed to the first main plate 110, the second main plate 120 and the first vertical partition 210 respectively. After the welding is completed, the weld of the inclined partition 230 is inspected to determine its welding quality. After the inclined partition 230 is welded, while the third main plate 130 has not yet been assembled, the second vertical partition 240 that needs to be assembled later is marked and positioned on the inclined partition 230 and the base plate 150 to facilitate the subsequent installation and positioning of the second vertical partition 240.

[0059] Further, in step S3, the welds between the first main plate 110, the second main plate 120 and the third main plate 130 are first pre-welded using root pass welding. The bottom plate 150 is welded to the first main plate 110 and the third main plate 130 respectively using backing welds. The top plate 160 is welded to the first main plate 110, the second main plate 120 and the third main plate 130 respectively using backing welds. Then, the welds between the first main plate 110, the second main plate 120 and the third main plate 130 are completed, and all welds are fully penetrated.

[0060] Understandably, such as Figure 3 and Figure 4 As shown, after the third main plate 130 is assembled with the first main plate 110 and the second main plate 120 to form a box shape, the welds between them are first welded using a root pass weld to prevent angular deformation. The welding between the bottom plate 150 and the first main plate 110 and the third main plate 130 is all done using a backing weld to fix the bottom plate 150. Then, the top plate 160 is assembled, also using a backing weld. After the top plate 160 is welded and fixed to the first main plate 110, the second main plate 120, and the third main plate 130, the welds between the first main plate 110, the second main plate 120, and the third main plate 130 are finally welded and fixed. The welds between the four main plates are all full penetration welds, with high strength, corrosion resistance, and aesthetic appearance. After welding is completed, weld flaw detection can be performed on the welds between the four main plates to determine their welding quality. This welding sequence helps ensure the stability of the box structure, reduces deformation, and facilitates correction.

[0061] Furthermore, in step S4, the welding of the four sides of the second vertical partition 240 is carried out by backing welding and all welds are fully penetrated.

[0062] Understandably, by using backing welding to weld the four edges of the second vertical partition 240, the second vertical partition 240 is welded and fixed to the second main plate 120, the third main plate 130, the bottom plate 150, and the first vertical partition 210, which facilitates the welding operation. The welds on the four edges of the second vertical partition 240 are all fully penetrated, with high weld strength, corrosion resistance, and aesthetic appearance. After the welding is completed, weld flaw detection can be performed on the welds on the four edges of the second vertical partition 240 to determine its welding quality.

[0063] Furthermore, in step S5, the fourth main plate 140 is welded to the second main plate 120, the third main plate 130 and the base plate 150 by means of backing welding, and the welds are all full penetration.

[0064] Understandably, the welding between the fourth main plate 140 and the second main plate 120, the third main plate 130 and the base plate 150 is completed by using a backing welding method to ensure the quality of the weld. The welds between the fourth main plate 140 and the second main plate 120, the third main plate 130 and the base plate 150 are all full penetration welds with high strength, corrosion resistance and aesthetic appearance. After the welding is completed, weld flaw detection can be performed on the welds around the fourth main plate 140 to determine its welding quality.

[0065] Further, in step S5, the fourth main body plate 140 is provided with two and is distributed at intervals in the left and right direction, so that a strip groove 103 is formed between the first vertical partition 210 and the two fourth main body plates 140. The groove 103 is plug welded to complete the welding between the first vertical partition 210 and the two fourth main body plates 140.

[0066] Understandably, such as Figure 2 and Figure 4 As shown, two fourth main body plates 140 are spaced apart in the left-right direction, with a spacing approximately equal to the thickness of the first vertical partition plate 210. This creates a strip-shaped groove 103 extending in the up-down direction between the first vertical partition plate 210 and the two fourth main body plates 140. The cross-section of the strip-shaped groove 103 is roughly U-shaped. A plug weld is performed on the groove to complete the welding between the first vertical partition plate 210 and the two fourth main body plates 140, improving structural stability and reliability. After welding, the weld is inspected for flaws to determine its quality. If the weld passes the flaw inspection, the plug weld can be ground to make the weld smooth and aesthetically pleasing. By using two fourth main body plates 140 in a double-door configuration to plug weld the first vertical partition plate 210, and performing overall welding, the risk of weld lamellar tearing is reduced, facilitating use.

[0067] Furthermore, the welding of the first main plate 110, the second main plate 120, the third main plate 130, the fourth main plate 140 and the first vertical partition 210 all adopt the measures of preheating before welding and heat preservation after welding.

[0068] Understandably, the first main plate 110, the second main plate 120, the third main plate 130, the fourth main plate 140, and the first vertical partition 210 are all relatively important plates in the multi-partition box-type node. By adopting preheating before welding and heat preservation after welding, it is beneficial to ensure the welding quality of the first main plate 110, the second main plate 120, the third main plate 130, the fourth main plate 140, and the first vertical partition 210, and improve the mechanical properties of the weld. In practical applications, in addition to the above-mentioned plates, other plates can also adopt preheating before welding and heat preservation after welding according to the ambient temperature conditions on site. The specific settings can be determined according to the actual needs of use.

[0069] Furthermore, the multi-partition box-type node includes brackets 310 and angle steel 320. The structure obtained after completing step S6 is inspected and corrected, and then the brackets 310 and angle steel 320 are assembled and welded at preset positions.

[0070] Understandably, such as Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the multi-partition box-type node also includes multiple brackets 310 and multiple angle steels 320. The multiple brackets 310 and multiple angle steels 320 are arranged around the box-type body 100. After completing step S6, the manufactured structure is first inspected and corrected. After the inspection and correction are completed, the brackets 310 and angle steels 320 are assembled and welded at preset positions as needed to connect to the outer beam and transfer the load from the outer beam. In actual applications, the number of brackets 310 and angle steels 320, the welding positions, etc. can be set according to actual usage needs, and are not limited here.

[0071] The multi-partition box-type node according to the second aspect of the present invention is manufactured using the manufacturing method of the multi-partition box-type node according to the first aspect of the present invention described above.

[0072] According to the embodiments of the present invention, the multi-partition box-type node, by adopting the above-described manufacturing method of the multi-partition box-type node, optimizes the welding sequence and structural design, so that all partitions in the partition area 101 can meet the requirements of four-sided welding. By adjusting the welding sequence, the problems of weld conflict and inability to weld between partitions in opposite directions are solved, ensuring the welding quality of the welds, and making the resulting multi-partition box-type node structure stable, reliable and easy to use.

[0073] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
