Description

Technical field

[0001] The present application relates to the technical field of building panels and relates in particular to a structural tube panel and a manufacturing process. State of the art

[0002] In the construction industry, hollow-core slabs solve the problem of significant material waste associated with solid slabs, which is why they are already widely used in this sector. Currently, Chinese utility model patent number CN219033774U, entitled "Sandwich Metal Construction Panel," specifically discloses that after welding the closed end and the alignment hole, the overall performance of the corresponding welded panel end face can be ensured without the need for brazing. Welding can be performed using conventional welding methods, allowing for more convenient operation, a higher level of technological maturity, and lower costs.

[0003] The aforementioned well-known technique can complete production without soldering, thus solving the problem of high costs in the manufacture of hollow plates. However, the following problems remain, which can impair the structural strength of the plate.

[0004] 1. Due to the limited thickness of the cover plate, the fitting projection at the closed end is also adapted to the thickness of the cover plate; therefore, the thickness of the fitting projection is also limited. This structural design results in a relatively small weld area between the fitting projection and the alignment hole on the cover plate after assembly.

[0005] 2. With existing plates that use conventional welding processes, filler material is required to fill and join two metal parts. Consequently, the strength of the weld is often lower than the strength of the base material. Content of the present application

[0006] The purpose of the present application is to provide a structural tube plate and a manufacturing process to solve at least one of the above-mentioned problems in the prior art.

[0007] To achieve the above purpose, the present application uses the following technical scheme:

[0008] A structural tube plate comprising a structural tube, an inner welded part, and a welded plate; wherein the inner welded part comprises a support plate and an inner perimeter edge; the inner perimeter edge is formed integrally on a circumference of the support plate and an outer wall of the inner perimeter edge abuts an inner wall of the structural tube; an outer perimeter edge is formed integrally on the welded plate, an inner surface of the outer perimeter edge is a fitting hole and the fitting hole abuts an outer wall of the structural tube; the outer perimeter edge and the structural tube are welded together and the inner perimeter edge and the structural tube are welded together; wherein the structural tube is a cylindrical structural tube and both the inner weld part and the fitting hole are circular structures adapted to a shape of the structural tube; the inner perimeter edge is perpendicular to the support plate and the outer perimeter edge is perpendicular to the weld plate.

[0009] In this technical concept, since the inner welded section encompasses the support plate and the inner perimeter edge, it can seal the end of the structural tube and provide stable internal support. Because the inner perimeter edge is formed integrally around the circumference of the support plate and its outer wall abuts the inner wall of the structural tube, it has a certain length. This increases the weld area between the inner perimeter edge and the inner wall of the structural tube, thereby improving the stability of the connection between the inner welded section and the structural tube. Since the outer perimeter edge is formed integrally on the welded plate, it can provide stable external support for the structural tube.Since the inner surface of the outer edge of the casing forms the fitting that rests against the outer wall of the structural tube, the outer edge of the casing has a height that exceeds the thickness of the weld plate. This increases the weld area between the outer edge of the casing and the outer wall of the structural tube, thereby improving the stability of the connection between the outer edge of the casing and the structural tube. Furthermore, the design of the outer and inner edges of the casing corresponds to a reinforcing structure on the surface of the casing, which can increase the structural strength of the weld plate and the inner welded section. To simplify the forming process of the structural tube and facilitate its assembly with the weld plate and the inner welded section, the structural tube is cylindrical.The inner weld and the fitting hole are both circular structures adapted to the shape of the structural tube. To ensure that both the inner and outer edges of the casing fit more stably against the structural tube and that the welding effect between the three is guaranteed, the inner edge of the casing and the support plate are perpendicular to each other, and the outer edge of the casing and the weld plate are also perpendicular to each other.

[0010] In summary, this technical concept, through the arranged inner circumferential edge on the inner weld section and the arranged outer circumferential edge on the weld plate, allows the weld area to be increased simultaneously from both the inside and outside of the structural tube. This ensures weld strength between the structural tube and the weld plate and increases the structural stability of the structural tube plate.

[0011] Furthermore, to ensure that the inner and outer surfaces of the structural tube end provide the same support effect and to improve the balance and stability of the internal and external support of the structural tube, the weld plate welded to the end of the structural tube is an end weld plate, and the inner weld part welded to the end of the structural tube is a terminal inner weld part. The positions of the end weld plate and the terminal inner weld part are aligned with each other.

[0012] Furthermore, to facilitate simultaneous, weld-proof joining from the outside of the weld plate and to increase welding efficiency, several structural tubes are arranged between two end weld plates. Both the inner and outer edges of these tubes extend towards the outside of the end weld plate.

[0013] Furthermore, to meet the demand for higher structural strength of the structural tube plate, the weld plate welded in the middle of the structural tube is a middle weld plate, and the inner weld part welded in the middle of the structural tube is a middle inner weld part. The middle weld plate is located between the two end weld plates, and the middle inner weld part is located between the two end inner weld parts.

[0014] Furthermore, to meet the demand for higher structural strength of the structural tube plate 1, several weld plates are arranged at intervals along the longitudinal direction of the structural tube. Several internal welds are also arranged at intervals along the longitudinal direction of the structural tube. Each pass hole of each weld plate has a corresponding internal weld.

[0015] Furthermore, to achieve a better weld at both ends of the structural tube and simultaneously minimize weld distortion, both the outer circumferential edge on the end weld plate and the inner circumferential edge of the terminal inner weld are end circumferential edges. The end circumferential edges are flush with the end of the structural tube. The surface where the end circumferential edge is flush with the end of the structural tube is the weld face. This end face is located relatively far from the weld plate and the support plate and is also at the outermost end of the structural tube. Therefore, the circumferential edge directs the weld face to a location that is farther away from the weld plate, the support plate, and the end of the structural tube.The welding temperature does not affect the surface of the weld plate or the structural tube, and deformations are limited to the perimeter edge area, thus reducing welding deformation.

[0016] Furthermore, to ensure that the inner and outer surfaces of the structural tube provide the same support effect and to improve the balance and stability of the internal and external supports, the height of the outer perimeter edge is identical to the height of the inner perimeter edge. To increase the structural strength of the welded plate, its thickness is greater than that of the structural tube.

[0017] The present application further provides a plate manufacturing process, comprising the structural tube plate described above, with the following steps: An inner welding part is installed at one end of each structural tube, and one end of each structural tube is aligned with several locating holes on a welding plate to form a first structure to be welded; The outer perimeter edge, the structural tube and the inner perimeter edge on the first structure to be welded are fixed by means of laser welding to form a first welded structure; At the other end of each structural tube, an inner welded part is installed, and the other end of each structural tube is aligned with several locating holes on another welding plate to form a second structure to be welded; The outer perimeter edge, the structural tube, and the inner perimeter edge on the second structure to be welded are fixed by laser welding to form a second welded structure; and The weld plate(s) located in the middle of the structural tube and the inner weld parts located in the middle of the structural tube are welded one after the other according to the number of layers of weld plates and the number of layers of inner weld parts.

[0018] This technical concept utilizes a laser welding process. Combined with the design of the outer and inner edges, the laser welding process melts the base materials themselves, requiring no filler material. Therefore, the weld strength achieved with this technical concept is higher compared to conventional welding.

[0019] The advantageous effect of the present application is as follows: In this technical concept, since the inner welded part comprises the support plate and the inner perimeter edge, the inner welded part can close the end of the structural tube and provide stable internal support to the structural tube. Because the inner perimeter edge is formed integrally around the circumference of the support plate and its outer wall abuts the inner wall of the structural tube, the inner perimeter edge has a certain extension length. This can increase the weld area between the inner perimeter edge and the inner wall of the structural tube, thereby improving the stability of the connection between the inner welded part and the structural tube. Because the outer perimeter edge is formed integrally on the welded plate, the outer perimeter edge can provide stable external support to the structural tube.Since the inner surface of the outer edge of the casing forms the fitting that rests against the outer wall of the structural tube, the outer edge of the casing has a height that exceeds the thickness of the weld plate. This increases the weld area between the outer edge of the casing and the outer wall of the structural tube, thereby improving the stability of the connection between the outer edge of the casing and the structural tube. Furthermore, the design of the outer and inner edges of the casing corresponds to a reinforcing structure on the surface of the casing, which can increase the structural strength of the weld plate and the inner welded section. To simplify the forming process of the structural tube and facilitate its assembly with the weld plate and the inner welded section, the structural tube is cylindrical.The inner weld and the fitting hole are both circular structures adapted to the shape of the structural tube. To ensure that both the inner and outer edges of the casing fit more stably against the structural tube and that the welding effect between the three is guaranteed, the inner edge of the casing and the support plate are perpendicular to each other, and the outer edge of the casing and the weld plate are also perpendicular to each other.

[0020] In summary, this technical concept, through the arranged inner circumferential edge on the inner weld section and the arranged outer circumferential edge on the weld plate, allows the weld area to be increased simultaneously from both the inside and outside of the structural tube. This ensures weld strength between the structural tube and the weld plate and increases the structural stability of the structural tube plate.

Detailed description of the embodiments

[0021] To clarify the technical solutions in the embodiments of the present application or in the prior art, the present application is presented below simply in conjunction with the figures and the description of the embodiments or the prior art. It is obvious that the following description of the figure structures only represents some embodiments of the present application. A person skilled in the art can obtain further figures from these figures without any creative effort. It should be noted that the description of these embodiments serves to facilitate understanding of the present application, but does not constitute a limitation of the present application. Design 1:

[0022] As in the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8 to Fig. As shown in Figure 9, this embodiment provides a structural tube plate comprising a structural tube 1, an inner welded section 2, and a welded plate 3. The inner welded section 2 comprises a support plate 2.1 and an inner perimeter edge 2.2. The inner perimeter edge 2.2 is formed integrally around the perimeter of the support plate 2.1. The outer wall of the inner perimeter edge 2.2 abuts the inner wall of the structural tube 1. An outer perimeter edge 3.1 is formed integrally on the welded plate 3. The inner surface of the outer perimeter edge 3.1 forms a fitting hole 3.2. The fitting hole 3.2 abuts the outer wall of the structural tube 1. The outer perimeter edge 3.1 and the structural tube 1, as well as the inner perimeter edge 2.2 and the structural tube 1, are welded together.

[0023] In this technical concept, since the inner welded part 2 comprises the support plate 2.1 and the inner circumferential edge 2.2, the inner welded part 2 can close the end of the structural tube 1 and provide stable internal support to the structural tube 1. Because the inner circumferential edge 2.2 is formed integrally around the circumference of the support plate 2.1 and its outer wall abuts the inner wall of the structural tube 1, the inner circumferential edge 2.2 has a certain extension length. This can increase the weld area between the inner circumferential edge 2.2 and the inner wall of the structural tube 1, thereby improving the stability of the connection between the inner welded part 2 and the structural tube 1. Because the outer circumferential edge 3.1 is formed integrally on the welded plate 3, the outer circumferential edge 3.1 can provide stable external support to the structural tube 1. Since the inner surface of the outer circumferential edge 3.1 forms the fitting hole 3.The outer edge 3.1, which abuts the outer wall of the structural tube 1, has a height that exceeds the thickness of the weld plate 3. This increases the weld area between the outer edge 3.1 and the outer wall of the structural tube 1, thereby improving the stability of the connection between the outer edge 3.1 and the structural tube 1. Furthermore, the design of the outer edge 3.1 and the inner edge 2.2 corresponds to a reinforcing structure on the plate surface, which increases the structural strength of the weld plate 3 and the inner weld 2. To simplify the forming structure of the structural tube 1 and facilitate its assembly with the weld plate 3 and the inner weld 2, the structural tube 1 is cylindrical. The inner weld 2 and the fitting 3 are also present.2 are both circular structures adapted to the shape of the structural tube 1. To ensure that both the inner perimeter edge 2.2 and the outer perimeter edge 3.1 can lie more stably against the structural tube 1 and that the welding effect between the three is guaranteed, the inner perimeter edge 2.2 and the support plate 2.1 are perpendicular to each other, and the outer perimeter edge 3.1 and the welding plate 3 are perpendicular to each other.

[0024] In summary, this technical concept, through the arranged inner circumferential edge 2.2 on the inner weld part 2 and the arranged outer circumferential edge 3.1 on the weld plate 3, allows the weld area to be increased simultaneously from both the inside and the outside of the structural tube 1. This ensures the weld strength between the structural tube 1 and the weld plate 3 and increases the structural stability of the structural tube plate 1.

[0025] Specifically, the inner perimeter edge 2.2 is formed in one piece on the circumference of the support plate 2.1 by bending, and the outer perimeter edge 3.1 is formed in one piece on the weld plate 3 by bending. Design 2:

[0026] This embodiment is based on an optimization of the above-mentioned embodiment 1.

[0027] To ensure that the inner and outer surfaces of the end of the structural tube 1 have the same supporting effect and to improve the balance and stability of the inner and outer support of the structural tube 1, the weld plate 3 welded to the end of the structural tube 1 is an end weld plate 5, and the inner weld part 2 welded to the end of the structural tube 1 is an end inner weld part 7. The positions of the end weld plate 5 and the end inner weld part 7 are aligned with each other. Design 3:

[0028] This embodiment is based on an optimization of the aforementioned embodiment 2.

[0029] To facilitate simultaneous weld-tight joining from the outside of the welding plate 3 and to increase welding efficiency, several structural tubes 1 are arranged between two end welding plates 53. Both the inner perimeter edge 2.2 and the outer perimeter edge 3.1 extend towards the outside of the end welding plate 53. The end of the structural tube 1 lies between the inner perimeter edge 2.2 and the outer perimeter edge 3.1. This allows the welding connection between the structural tube 1 and the welding plate 3 to be carried out from the outside of the welding plate 3 using conventional welding methods, thereby reducing welding costs. Design 4:

[0030] This embodiment is based on an optimization of the aforementioned embodiment 2.

[0031] To meet the demand for higher structural strength of the structural tube plate 1, the weld plate 3 welded to the center of the structural tube 1 is a middle weld plate 4, and the inner weld part 2 welded to the center of the structural tube 1 is a middle inner weld part 6. The middle weld plate 4 is located between the two end weld plates 5, and the middle inner weld part 6 is located between the two end inner weld parts 7. This means that the welding method of the middle weld plate 4 and the middle inner weld part 6 to the structural tube 1 is the same as that of the end weld plate 5 and the end inner weld part 7 to the structural tube 1; only the welding position on the structural tube 1 differs. Depending on the specific requirements, the number of weld plates 3 and the specific arrangement of the inner weld parts 2 can be adjusted accordingly. Design 5:

[0032] This embodiment is based on an optimization of the above-mentioned embodiment 1.

[0033] To meet the demand for higher structural strength of the structural tube plate 1, several weld plates 3 are arranged at intervals along the longitudinal direction of the structural tube 1. Several internal weld elements 2 are arranged at intervals along the longitudinal direction of the structural tube 1. Each pass hole 3.2 of each weld plate 3 has a corresponding internal weld element 2. Design 6:

[0034] This embodiment is based on an optimization of the above-mentioned embodiment 1.

[0035] To achieve a better weld at both ends of the structural tube 1 and simultaneously reduce weld distortion as much as possible, both the outer circumferential edge 3.1 on the end welding plate 5 and the inner circumferential edge 2.2 of the terminal inner weld part 7 are end circumferential edges. The end circumferential edges are flush with the end of the structural tube 1. The surface where the end circumferential edge is flush with the end of the structural tube 1 is the weld surface 8. This end face is located relatively far from the welding plate 3 and the support plate 2.1 and is also at the outermost end of the structural tube 1. Therefore, the circumferential edge directs the weld surface 8 to a position that is far from the welding plate 3, the support plate 2.1, and the end of the structural tube 1.The welding temperature does not affect the surface of the welding plate 3 or the structural tube 1, and deformations are limited to the perimeter edge area, thus reducing welding deformation. Design 7:

[0036] This embodiment is based on an optimization of the above-mentioned embodiment 1.

[0037] To ensure that the inner and outer surfaces of the structural tube 1 have the same supporting effect and to improve the balance and stability of the inner and outer supports of the structural tube 1, the height of the outer perimeter edge 3.1 is identical to the height of the inner perimeter edge 2.2. To increase the structural strength of the welded plate 3, the thickness of the welded plate 3 is greater than the thickness of the structural tube 1. Design 8:

[0038] The present application further provides a plate manufacturing process comprising a structural tube plate according to one of embodiments 1-9 and including the following steps:

[0039] An inner weld part 2 is installed at one end of each structural tube 1, and one end of each structural tube 1 is aligned with several locating holes 3.2 on a welding plate 3 to form a first structure to be welded;

[0040] The outer perimeter edge 3.1, the structural tube 1 and the inner perimeter edge 2.2 on the first structure to be welded are fixed by means of laser welding to form a first welded structure;

[0041] At the other end of each structural tube 1, an inner weld part 2 is installed, and the other end of each structural tube 1 is aligned with several locating holes 3.2 on another welding plate 3 to form a second structure to be welded;

[0042] The outer perimeter edge 3.1, the structural tube 1 and the inner perimeter edge 2.2 on the second structure to be welded are fixed by means of laser welding to form a second welded structure;

[0043] The weld plate(s) 3 located in the middle of the structural tube 1 and the inner weld parts 2 located in the middle of the structural tube 1 are welded one after the other according to the number of layers of the weld plates 3 and the number of layers of the inner weld parts 2.

[0044] This technical concept utilizes a laser welding process. In combination with the design of the outer perimeter edge 3.1 and the inner perimeter edge 2.2, the laser welding process involves the melting of the base materials themselves, requiring no filler material. Therefore, the weld strength achieved with this technical concept is higher compared to conventional welding.

[0045] Finally, it should be noted that the above-mentioned statements are merely preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. All amendments, equivalent replacements, improvements, etc., made in the spirit and principle of the present application should be included within the scope of protection of the present application.
