TECHNICAL FIELD

[0001] The present application relates to the technical field of water flashing construction, in particular to a metal water flashing edge closing structure. BACKGROUND

[0002] The profiled metal sheet is a kind of wall and roof cladding material for industrial buildings, which has the advantage of light weight, and in combination with light weight thermal insulation material, is an excellent cladding system for replacing traditional brick-concrete external walls.

[0003] This system is used for industrial buildings, which can reduce the work intensity, effectively improve the construction efficiency, has the advantage of cost performance, and because the metal sheet is thin and light, it has little effect on the main load-bearing structure, and the main structure component can also obtain the advantage of lightweight design.

[0004] According to its process characteristics, the profiled metal sheet is made into a kind of unidirectional extension plane sheet, and the side edges of adjacent sheets are connected through the pre-designed lap joints, and the head and tail of the sheet are connected through the water flashing edge closing.

[0005] This water flashing metal sheet is made by bending / rolling, used for connecting the head and tail of the profiled metal sheet, and mainly used to eliminate the temperature stress in the length direction of the sheet, and at the same time provides a unique building appearance.

[0006] The existing water flashing edge closing structure has a flat surface protruding outside the transversely arranged profiled sheet, and the cross-sectional shape is a few characters. In some cases, customers need a water flashing without a flat surface, so there is also a water flashing with a T-shaped edge closing.

[0007] In actual construction operation, it is found that the effect of this T-shaped edge closing is not perfect, and the reason is that the T-shaped rib tip lacks sufficient rigidity, and there is a chance of distortion in the process of production, transportation, on-site handling, and installation, which causes poor straightness after installation and the appearance is difficult to be accepted by customers.

[0008] In summary, there is currently a lack of a metal water flashing edge closing structure to solve the problem that the existing structure has a chance of distortion in the process of production, transportation, on-site handling, and installation, which causes damage to the structure. SUMMARY

[0009] The purpose of the present application is to overcome the defects of the prior art and provide a metal water flashing edge closing structure to solve or partially solve the problem that the existing structure has a chance of distortion in the process of production, transportation, on-site handling, and installation, which causes damage to the structure.

[0010] The purpose of the present application can be achieved by the following technical solutions:

[0011] The application provides a metal flashing edge closing structure, which comprises a first metal plate and a second metal plate arranged in parallel, and a flashing edge closing module used for connecting the first metal plate and the second metal plate, wherein the flashing edge closing module comprises:

[0012] a first connecting plate connected with the first metal plate and the second metal plate respectively;

[0013] a second connecting plate connected with the first connecting plate, wherein the second connecting plate is provided with a protruding part on the side far away from the first connecting plate, and the cross section of the area surrounded by the protruding part is circular or elliptical.

[0014] As a preferred technical scheme, the first connecting plate and the second connecting plate are arranged perpendicularly.

[0015] As a preferred technical scheme, the area surrounded by the protruding part is hollow.

[0016] As a preferred technical scheme, the flashing edge closing module further comprises a solid rod matched with the area surrounded by the protruding part.

[0017] As a preferred technical scheme, a plurality of the metal flashing edge closing structures are connected with other metal flashing edge closing structures through the solid rod.

[0018] As a preferred technical scheme, the edge of the flashing edge closing module is chamfered.

[0019] As a preferred technical scheme, the first metal plate and the second metal plate are respectively abutted with the second connecting plate.

[0020] As a preferred technical scheme, the flashing edge closing module is threadedly connected with the first metal plate and the second metal plate respectively.

[0021] As a preferred technical scheme, the first metal plate and the second metal plate are wavy.

[0022] As a preferred technical scheme, the first connecting plate, the second connecting plate and the protruding part are integrally formed.

[0023] Compared with the prior art, the application has the following advantages:

[0024] (1) By arranging the protruding part with a circular or elliptical cross section on the second connecting plate, compared with the traditional flashing element with a U-shaped edge closing structure and the flashing element with a T-shaped edge closing structure, the protruding part is free of edges, so that the probability of damage of the flashing edge closing structure caused by bending is effectively reduced, thereby solving or partially solving the problem that the existing structure is distorted during the production, transportation, on-site handling and installation, and is damaged.

[0025] (2) The rigid inner liner rod left in the spherical flashing member is used as the connection of the flashing member lengthening, ensures the quality of installation, and can improve the construction speed.

[0026] (3) The area surrounded by the protruding part can be equipped with the inner liner rod matched therewith, so that the flashing structure after the folding edge production maintains the design circular arc appearance, and has excellent quality.

[0027] (4) The flashing edge structure is slender in shape, and the geometric line feeling reflects the light and delicate characteristics of the metal enclosure system, and improves the aesthetic appearance. BRIEF DESCRIPTION OF DRAWINGS

[0036] Embodiment 1

[0037] As Figures 1-4 described, the present embodiment provides a metal flashing edge closing structure, as Figures 1-2 described, the edge closing structure includes a first metal plate 1 and a second metal plate 2 arranged in parallel and in a wavy shape, the first metal plate 1 is connected with the second metal plate 2 through a flashing edge closing module 3, the flashing edge closing module 3 is threadedly connected with the first metal plate 1 and the second metal plate 2 respectively, and the edge of the flashing edge closing module 3 is chamfered, wherein the flashing edge closing module 3 includes:

[0038] a first connecting plate 4 connected with the first metal plate 1 and the second metal plate 2 respectively;

[0039] a second connecting plate 5 connected with the first connecting plate 4, the first connecting plate 4 and the second connecting plate 5 are arranged perpendicularly, the second connecting plate 5 is provided with a protruding part 6 on the side away from the first connecting plate 4, the protruding part 6 encloses a region with a circular or elliptical cross section, as Figure 3 described, the protruding part 6 encloses a region with a solid rod 7 cooperating therewith, and the first connecting plate 4, the second connecting plate 5 and the protruding part 6 are integrally formed.

[0040] As Figure 4 described, it is a schematic diagram of multiple metal flashing edge closing structures abutting, the multiple metal flashing edge closing structures are connected with other metal flashing edge closing structures through the solid rod 7.

[0041] The present embodiment adds a circular protruding part to the tip of the T-shaped edge closing flashing part, which is referred to as "spherical flashing edge closing" below. The circular head of the expansion has rigidity, which can overcome the distortion phenomenon in the process of manufacturing, transportation and on-site handling and installation, and the form after installation is as Figure 1 shown.

[0042] The difficulty in applying such a flashing edge closing lies in the manufacturing process of the spherical flashing edge closing. The bending machine can be used to manufacture the flashing part with a bent edge. However, it is difficult for the bending machine to make a very smooth curve shape for the non-linear part of the circular arc type of the spherical flashing, and it is also difficult to make the shape consistent along the entire length of the flashing edge closing part.

[0043] The manufacturing method proposed in the present embodiment is:

[0044] As Figure 3The circular arc part of the spherical flashing edge member is internally provided with a rigid lining rod member, the cross section of which is circular in the spherical flashing edge member according to the present application, and other cross section forms (such as ellipse, water drop, polygon, etc.) can be used to make other types of curved surface shapes.

[0045] The rigid lining rod member is used to limit the collapse of the curved part of the flashing member due to the compression of the knife edge of the folding machine, and to maintain the curved shape during folding, so as to obtain the intended curved shape of the flashing member.

[0046] After the spherical flashing folding is completed, the rigid lining rod member remains in the spherical flashing member as a component of the flashing member, and is used to enhance the rigidity of the flashing member.

[0047] As Figure 4 The rigid lining rod member remaining in the spherical flashing member is used as a connection for lengthening the flashing member, and ensures the quality of the flashing installation.

[0048] The improvements and advantages of the present embodiment are as follows:

[0049] A. Compared with the original scheme of the U-shaped flashing, the spherical flashing edge shape is slender, and the geometric line feeling reflects the light and delicate characteristics of the metal enclosure system;

[0050] B. Compared with the original scheme of the T-shaped flashing edge, the spherical flashing edge provides better out-of-plane rigidity, and improves the defects of distortion after the T-shaped flashing is installed;

[0051] C. Through the specific shape of the rigid lining rod member, the spherical flashing maintains the designed circular arc appearance after folding, and has excellent quality;

[0052] D. The rigid lining rod member remaining in the spherical flashing member is used as a connection for lengthening the flashing member, and ensures the quality of the flashing installation;

[0053] Embodiment 2

[0054] Compared with Embodiment 1, the rigid lining rod member in the present embodiment is extracted from the flashing member after the spherical flashing folding is completed, and can be used for subsequent product manufacturing. In addition, the first metal plate 1 and the second metal plate 2 respectively abut against the second connecting plate 5, further improving the aesthetic appearance.

[0055] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
