Description

Technical Field

[0001] The utility model belongs to the technical field of waterproof construction, and in particular relates to a flashing structure of horizontal and vertical nodes of large corrugated enclosure outer plates. Background Art

[0002] Colored steel profiled sheets are often used for roofs, walls, and interior and exterior wall decoration of many warehouse buildings, special buildings, and large-span steel structures. Colored steel profiled sheets are usually made into wavy curved sheets. They are light, high-strength, and easy and quick to construct. They are now widely used and are becoming more and more common in building exterior walls. When wavy colored steel profiled sheets are used for exterior walls, the construction focus is usually on two points: one is the external appearance of the arrangement and connection of the wavy sheets; the other is the flashing construction at the connection position of the wavy sheets.

[0003] In traditional wall enclosure systems, wall panels are mostly arranged by simply arranging the corrugated plates horizontally or vertically, and a flashing plate is set at the junction of two adjacent corrugated plates. For example, my country's utility model patent, patent number 202211722914.X, was applied for on December 30, 2022, and discloses a metal flashing edge structure, including a first metal plate and a second metal plate arranged in parallel, and a flashing edge module is installed at the connection position between the first metal plate and the second metal plate. The flashing edge module includes: a first connecting plate, which is respectively connected to the first metal plate and the second metal plate on both sides, and the first connecting plate is located on the inner side of the metal plate; a second connecting plate, which is connected to the first connecting plate, and its position is in the gap between the ends of the first metal plate and the second metal plate, and the outer side of the second connecting plate extends to the outer side of the metal plate. In this scheme, the first connecting plate is used to stop water leaking inward from the edge of the first metal plate or the second metal plate, thereby achieving the purpose of waterproof joints.

[0004] In today's industrial plants, the plant enclosure system must not only have the basic function of sheltering from wind and rain, but also, for the sake of corporate image, the owners have higher requirements for the aesthetics of the appearance. 1) In traditional construction, the architectural form of simply arranging the corrugated plates horizontally or vertically is dull and not beautiful enough; and if it is designed as a comprehensive arrangement of horizontal and vertical rows, there is a lack of flashing structures that can simultaneously connect with the horizontal and vertical nodes of the large corrugated plates; 2) In the existing wall enclosure system flashing method, the corrugated plates are mostly fitted and set on the outside of the flashing plates. Since the size of the corrugated plates needs to be cut and modified according to the actual working conditions, the ends will inevitably leave cutting burrs, especially when cutting parallel to the waves. Since it is difficult to fix the corrugated plates in this direction, it is more likely to have non-straight tangents, burrs, and sawtooth. The exposed burrs affect the beauty of the project. The appearance of the existing flashing structure needs to be improved after construction. Utility Model Content

[0005] The utility model solves the problems in the prior art, thereby providing a flashing structure applied to the connection nodes of horizontal and vertical wave plates, and can improve the aesthetic appearance of the project.

[0032] The present invention is further described below in conjunction with embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0033] See also Figure 1 The existing flashing structure between corrugated plates is symmetrical on both sides, and both have a certain width of plate surface that fits with the side corrugated plates. The middle baffle is used to constrain the verticality of the ends of the corrugated plates on both sides. If the old flashing structure is directly transferred to the horizontal and vertical corrugated plates, the side edges of the vertical corrugated plates are difficult to cut smoothly and cannot fit with the side of the flashing, which will cause burrs and exposed saw teeth, which will greatly affect the appearance of the project and reduce the corporate image.

[0034] The utility model is intended to develop a design project with more corrugated plate pattern arrangement, and a flashing structure is designed for the connection position of the horizontal and vertical rows of corrugated plates to ensure the appearance of the project. Figures 2 to 4 ,

[0035] A flashing structure for horizontal and vertical nodes of a large corrugated enclosure outer plate, comprising a left corrugated plate 2 and a right corrugated plate 3, wherein a flashing plate is arranged at the junction of the left corrugated plate 2 and the right corrugated plate 3, the left corrugated plate 2 is arranged in a horizontal row, and the right corrugated plate 3 is arranged in a vertical row, and the flashing plate is composed of a first component 4 and a second component 5;

[0036] The first component 4 is in a Z-shape as a whole, and includes a first water stop baffle 401 attached to the outer surface of the steel frame, the right end of the first water stop baffle 401 is vertically fixed to the first support baffle 402, the outer end of the first support baffle 402 is fixed to the first decorative baffle 403, and the right end of the first decorative baffle 403 is fixed to the first connecting piece 404 bent toward the steel structure 1;

[0037] The second component 5 is C-shaped as a whole, and includes a second water stop baffle 501 attached to the outer surface of the steel frame, the left end of the second water stop baffle 501 is vertically fixed to the second support baffle 502, the outer end of the second support baffle 502 is fixed to the second decorative baffle 503, and the right end of the second decorative baffle 503 is fixed to the second connecting piece bent toward the steel structure 1;

[0038] The second component 5 is embedded in the rear of the first component 4, between the first supporting baffle 402 and the first connecting piece 404, and the second connecting piece and the first connecting piece 404 are fixed by rivets 10;

[0039] The end of the left corrugated plate 2 is arranged outside the first water stop baffle 401 , and the side of the right corrugated plate 3 is inserted into the inside of the second component 5 .

[0040] The sizes of the first component 4 and the second component 5 of the flashing structure are customized according to the engineering design requirements. Generally, the width of the second water stop baffle 501 is 100 mm, the width of the second support baffle 502 is set according to the flashing shape height required by the project, and the second decorative baffle 503 is set according to the flashing shape width required by the project; the same is true for each plate in the first component 4, the width of the first water stop baffle 401 is generally 40 mm, the width of the first support baffle 402 is 2 mm larger than the width of the second support baffle 502, and the width of the first decorative baffle 403 is 2 mm larger than the width of the second decorative baffle 503.

[0041] Usually the vertical wall beam width is not enough to complete the fixing of the flashing structure of the utility model, so the conventional structure widening method is adopted to fix the cold-bent angle steel 8 on the side of the wall beam to make up the width, see Figure 2 .

[0042] The trough positions of the left corrugated plate 2 and the right corrugated plate 3 need to be fixed to the steel structure 1 using self-tapping screws 9.

[0043] Optionally, the outer ends of the first water stop baffle 401 and the second water stop baffle 501 are also provided with a folded edge 6, and the outer side of the folded edge 6 is offset in the direction away from the steel frame. The width of the folded edge 6 is 10 mm, and the angle is about 150 degrees. The design of the folded edge 6 can effectively stop the moisture that has penetrated into the external protective flashing structure from continuing to penetrate into the steel structure 1, and it can make the moisture flow to the ground along the folded edge 6.

[0044] Optional, see Figure 5 A sealing plug 7 is fixed on the outside of the first water stop baffle 401. The outer surface of the sealing plug 7 is a concave-convex shape that matches the waves of the horizontal row of corrugated plates. The inner and outer surfaces of the sealing plug 7 are provided with glue, and a first connecting nail is also provided. The first connecting nail penetrates the left corrugated plate 2, the sealing plug 7, the first component 4 and is fixed to the steel structure 1. In this example, the edges of the horizontal row of corrugated plates are firmly fixed and can greatly reduce rainwater that penetrates into the inside.

[0045] Corrugated plates arranged in vertical rows need to be cut and prepared parallel to the corrugations. During construction, the corrugated plates are often cut on site according to the construction conditions of the exterior wall in front. However, the on-site cutting equipment and plate fixing tools are limited. In addition, the plate fixing is unstable in the vertical cutting direction, which makes the cutting line discontinuous. Burrs and sawtooth are very common. The defects of the plate material can only be compensated during installation. The C-shaped cavity of the second flashing plate component 5 designed in the utility model provides such a construction adjustment space for the vertical corrugated plate.

[0046] See also Figure 6 , Figure 7 When the right corrugated plate 3 is installed in the second component 5, if the side is a trough, the fixed position is set as follows: the adjacent crest corresponds to the first connecting piece 404, and the crest is fixedly connected to the second water stop baffle 501; when the right corrugated plate 3 is installed in the second component 5, if the side is a crest, the fixed position is set as follows: the adjacent trough abuts against the first connecting piece 404, and the next crest is fixed to the steel structure 1. The opening width of the second component of the utility model (i.e., the interval between the upper end of the second connecting piece and the second water stop baffle) is less than or equal to the thickness of the right corrugated plate.

[0047] After the side edge of the vertical corrugated plate is inserted into the second assembly 5, the burrs can no longer be seen from the building appearance. However, when the crest corresponds to the first connecting piece 404, a more obvious gap will appear after installation. In order to further improve the appearance, the utility model also designs a flexible sealing strip 11, see Figure 8 One end of the flexible sealing strip 11 is fixed between the first connecting piece 404 and the second connecting piece, and the other end abuts against the peak surface of the right corrugated plate 3 opposite to the first connecting piece 404; further, the flexible sealing strip 11 is a rubber plate with plastic deformation ability, which is bent and the other end is elastically attached to the surface of the right corrugated plate 3.

[0048] The beneficial effects of the utility model are:

[0049] 1) The utility model provides a flashing structure that can simultaneously connect the horizontal and vertical corrugated plates, filling the gap in current construction and providing a large design space for improving the design sense of corrugated plate decoration buildings; 2) The utility model hides the side edges of the vertical corrugated plates to solve the problem of exposed rough edges and further enhances the beauty of the building's appearance. 3) The flashing board of the utility model has a beautiful appearance and is decorative on the basis of having a waterproof function.

[0050] The above description is only a preferred feasible embodiment of the present utility model, and does not limit the scope of rights of the present utility model. All equivalent changes made using the contents of the present utility model specification and its drawings are included in the scope of rights of the present utility model.
