Description

Technical Field

[0001] The utility model relates to the technical field of building structural components, in particular to a wave crest outer plug for a roof system. Background Art

[0002] There are various shapes of waterproof fittings for industrial buildings, which are mostly used for waterproof sealing of roof systems such as pipelines, ventilation, air conditioning, electricity, heating, etc. In the metal enclosure structure of the roof, waterproof fittings adapted to specific system nodes are particularly important.

[0003] The inventor has learned that when sealing the end of the wave crest in the roof system, a rigid waterproof fitting (outer plug) is generally used. This rigid waterproof fitting is not deformable and is not convenient for achieving a tight fit between itself, the wave crest and the roof panel. As a result, water leakage is likely to occur at the gap between the waterproof fitting and the roof panel. In addition, in some structural settings, flexible waterproof fittings are used, but their heat resistance is insufficient, and they are prone to deformation due to thermal expansion and contraction after long-term use, resulting in local water leakage of the waterproof fitting. Summary of the Utility Model

[0004] The utility model provides a wave crest outer plug for a roof system, which can solve at least one of the above technical problems.

[0005] To solve the above technical problems, one or more embodiments of the utility model provide a wave crest outer plug for a roof system, including a flexible pressing sleeve, a flexible cover plate and a metal skeleton. The pressing sleeve includes a bottom plate, an inclined plate and a top sleeve arranged in sequence from bottom to top. The bottom plate has an opening vertically penetrating itself, and the opening penetrates the bottom plate along a first direction in the horizontal direction. The opening of the bottom plate is used to insert the end of the wave crest along its length direction. The top sleeve is nested on the upper part of the wave crest, and both sides of the top sleeve along the direction perpendicular to the length of the wave crest are respectively connected to the bottom plate through the inclined plate; the connection position between the inclined plate and the bottom plate is at the end of the bottom plate along the first direction; the cover plate can fill the gap between the bottom plate, the inclined plate and the top sleeve; the metal skeleton is nested inside the pressing sleeve.

[0006] The beneficial effects of the above one or more technical solutions are as follows:

[0007] Compared with a completely rigid or completely flexible outer plug, the outer plug in this solution includes a flexible pressing sleeve, a flexible cover plate and a metal skeleton. The metal skeleton is nested in the pressing sleeve, and the pressing sleeve includes a bottom plate, an inclined plate and a top plate. This setting method facilitates the use of the metal skeleton to support the pressing sleeve, avoiding deformation due to thermal expansion and contraction caused by poor heat resistance of the pressing sleeve; and the metal skeleton does not directly contact the wave crest and the roof panel, and the flexible pressing sleeve can fit the wave crest and the roof panel through its own deformation, reducing the problem of water leakage caused by the generation of gaps between the outer plug and the wave crest and the roof panel.

[0008] In addition, in this solution, the metal skeleton is only provided at the compression sleeve and not in the cover plate. This setting method can reduce the use of the metal skeleton and the difficulty of deforming the entire external plug to adapt to the shape and size of the wave crest and the roof panel.

[0009] The wave crest waterproof external plug of this solution has a flexible and adjustable compression sleeve, which can adapt to the waterproof seal at the end of the wave crest in most metal roof systems through its own deformation. Brief Description of the Drawings

However, this application can also be implemented in other ways different from those described herein. Therefore, the protection scope of this application is not limited by the specific embodiments disclosed below.

[0020] In addition, in the description of the present application, it should be understood that the orientation or positional relationship indicated by terms such as "top", "bottom", "inner", "outer", "axial direction", "radial direction", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0021] In the present application, unless otherwise clearly specified and limited, terms such as "install", "connect", "join", "fix", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, an electrical connection, or a communication connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] See Figure 6 - Figure 7 , which provides an application scenario of a wave crest outer plug. The roofing system includes a plurality of roof panels 7 arranged in sequence along a certain direction. The edge of the roof panel 7 is provided with a folded edge that turns upward. The folded edges of every two roof panels 7 are butted to form a wave crest 6. Above the roofing system, there is a fan base 4, and the fan base 4 is used to install and support a fan. It can be seen that the wave crest 6 is disconnected at a position close to the fan base 4, and one end of the wave crest 6 along its own length direction close to the fan base 4 is disconnected to form an end to be plugged. The plug 5 is sleeved on the end formed by the disconnection of the wave crest 6, and the lower end of the plug 5 is connected to the roof panel 7 or the plate member extended from the fan base 4.

[0023] In Figure 6 - Figure 7 , the plug 5 is likely to have a gap with the wave crest 6 due to shape mismatch or thermal expansion and contraction, thus causing water leakage.

[0024] See Figure 1 - Figure 5 , an embodiment of the present utility model provides a wave crest 6 outer plug for a roofing system, including a flexible pressing sleeve 1, a flexible cover plate 2, and a metal skeleton 3. The pressing sleeve 1 includes a bottom plate 101, an inclined plate 105, and a top sleeve 102 arranged in sequence from bottom to top. The bottom plate 101 has an opening that vertically penetrates itself, and the opening penetrates the bottom plate 101 along a first direction in the horizontal direction. The opening of the bottom plate 101 is used to insert the end of the wave crest 6 along its own length direction.

[0025] The top sleeve 102 is nested on the upper part of the wave crest 6. The two sides of the top sleeve 102 along the length direction perpendicular to the wave crest 6 are respectively connected to the bottom plate 101 through the inclined plates 105. The connection positions of the inclined plates 105 and the bottom plate 101 are at the ends of the bottom plate 101 along the first direction. The cover plate 2 can fill the gap between the bottom plate 101, the inclined plates 105 and the top sleeve 102. The metal framework 3 is nested inside the compression sleeve 1.

[0026] Specifically, the compression sleeve 1 and the cover plate 2 here are made of materials such as sealing rubber or silica gel. When using sealing rubber, it is foamed or non-foamed ethylene propylene diene monomer rubber, foamed or non-foamed nitrile rubber, foamed or non-foamed silicone rubber, etc., with a density of 1.0 - 1.35 g / cm3 and 15% - 30% inorganic filler. The performance evaluation refers to "GB / T 24498 - 2009 Sealing Rubber Strips for Building Doors, Windows and Curtain Walls", and it has physical properties such as high raw rubber content, anti-aging, ozone resistance, ultraviolet resistance, high and low temperature resistance, and tear resistance.

[0027] In the case of using sealing rubber, the compression sleeve of this solution has physical properties such as anti-aging, ozone resistance, ultraviolet resistance, high and low temperature resistance, tear resistance, and corrosion resistance.

[0028] Specifically, the metal framework 3 here is a bendable and corrosion-resistant metal sheet. The material can be a low yield strength steel sheet or an alloy aluminum sheet, preferably an alloy aluminum sheet, with a thickness of 0.5 mm - 0.8 mm and a yield strength of 30 - 200 MPa. Using a bendable metal sheet, it can be easily bent into shape by hand. The metal framework 3 in this embodiment is completely coated with sealing rubber, and the thickness of the sealing rubber coating is 1 mm - 3 mm.

[0029] Specifically, the thickness of the compression sleeve 1 is 5 mm; the thickness of the cover body is 2.5 mm.

[0030] In some structural settings, the bottom plate 101 is a horizontal U-shaped, and the top sleeve 102 is U-shaped with its opening facing downwards.

[0031] In some other structural settings, the bottom plate 101 and the top sleeve 102 can adopt other structural forms. For example, the bottom plate 101 is a square plate, and an opening running through itself vertically and in the first direction is provided in the square plate.

[0032] In this embodiment, a telescopic opening 103 is provided at the end of the bottom plate 101 along the direction opposite to the first direction. The telescopic opening 103 runs through the bottom plate 101 vertically. Specifically, the length of the telescopic opening 103 is 15 mm and the width is 4 mm.

[0033] In this embodiment, the metal framework 3 includes a diagonal brace 301, a top brace 304 and two bottom braces 303. The diagonal brace 301 is embedded in the inclined plate 105, the top brace 304 is embedded in the top sleeve 102, and the two bottom braces 303 are embedded in the two sides of the bottom plate 101 along the direction perpendicular to the first direction.

[0034] In this embodiment, the oblique support 301 and the top support 304 are integrally formed, and the oblique support 301 and the bottom support 303 are separately provided.

[0035] In this embodiment, the upper surface of the pressing sleeve 1 is provided with a plurality of positioning grooves 104, and the metal frame 3 is provided with connection holes 302 respectively corresponding to the positioning grooves 104. Specifically, the positioning grooves 104 are circular grooves with a depth of 0.2 mm and a diameter of 6 mm.

[0036] In this embodiment, a vertical positioning plate 107 is provided in the top sleeve 102 , and the positioning plate 107 is fixed to the inner wall surface of the top sleeve 102 .

[0037] In this embodiment, the inner wall surface of the inclined plate 105 is provided with a plurality of spacers 108, and the spacers 108 are perpendicular to the first direction. Specifically, after the pressing sleeve 1 is installed, the spacers 108 are pressed between the outer surface of the crest 6 and the inner wall surface of the inclined plate 105, thereby facilitating the sealing between the pressing sleeve 1 and the crest 6 and reducing the probability of water leakage at the outer plug.

[0038] In this embodiment, a plurality of corrugated strips 109 are provided on the lower surface of the bottom plate 101. This arrangement facilitates the use of the corrugated strips 109 at the bottom to increase the water tightness and air tightness of the system. Specifically, the corrugated strips 109 are evenly arranged on the lower surface of the bottom plate 101.

[0039] Specifically, the height of the protrusion of the corrugated strip 109 is 0.4 mm, and the corrugated strip 109 can also be replaced by a straight line; the height of the spacer 108 is 2.5 mm and the width is 1 mm.

[0040] When in use, the user first bends the pressing sleeve 1 by hand to make the shape of the pressing sleeve 1 match the shape of the end of the crest 6 to be blocked. The lower surface of the bottom plate 101 is sealed with butyl glue or polyurethane glue, and then placed on the end of the crest 6, and the end of the crest 6 stops at the limit plate to prevent the crest 6 from contacting the cover plate 2. Finally, the positioning groove 104 is fixed with screws.
