Abstract
Description
Technical Field
[0001] The present application relates to the technical field of building materials, and in particular to corner sandwich panels and corner curtain walls. Background Art
[0002] To ensure the thermal insulation, waterproofing, and aesthetics of metal buildings, their exteriors are typically covered with metal curtain walls. Most metal buildings are rectangular, with adjacent curtain walls perpendicular to each other. However, as aesthetics become increasingly important, transition surfaces are often added between adjacent perpendicular curtain walls. These transition surfaces can be either rounded or chamfered, enhancing the aesthetics of metal buildings.
[0003] However, since ordinary sandwich panels are rectangular, even if a chamfered curtain wall is laid between two perpendicular curtain walls, there is an angle gap between the side edges of the two adjacent curtain walls at the corner, which cannot fit well. A filling device must be installed at the angle gap to fill the gap, which not only slows down the construction progress and increases the cost, but also causes poor waterproofing and thermal insulation performance at the angle gap. Utility Model Content
[0004] In view of the above problems, an embodiment of the present application is proposed. The purpose of the embodiment of the present application is to provide a corner sandwich panel with an inclined surface and a side surface that can closely fit with the side surface of a horizontal or vertical sandwich panel.
[0005] To achieve this goal, the present invention adopts the following technical solutions:
[0006] A corner sandwich panel,
[0007] One of the upper and lower sides of the corner sandwich panel is a male buckle structure, and the other is a female buckle structure that cooperates with the male buckle structure;
[0008] The left and right sides of the corner sandwich panel are provided with inclined side surfaces that are inclined toward each other, and the angles between the two inclined side surfaces and the vertical plane are respectively a first angle and a second angle, and the sum of the first angle and the second angle is 90°.
[0009] As an optional solution, the first angle and the second angle may be equal or different.
[0010] As an optional solution, the corner sandwich panel includes two layers of inner and outer metal plates and a sandwich layer between the two layers of the metal plates.
[0011] As an alternative,
[0012] The two metal plates are aligned with the center of the sandwich layer;
[0013] The left side and the right side of the sandwich layer are the oblique side surfaces;
[0014] The length of the outer metal plate in the left-right direction is longer than the outer side surface of the sandwich layer;
[0015] The portion of the outer metal plate that is longer than the sandwich layer is bent toward the sandwich layer to form an edge structure that abuts against the sandwich layer.
[0016] As an alternative,
[0017] The lengths of the inner and outer metal plates in the vertical direction are longer than the length of the sandwich layer in the vertical direction, and the parts longer than the sandwich layer are bent toward the sandwich layer to form an edge structure abutting against the sandwich layer.
[0018] As an optional solution, the edges of the inner and outer layers of the metal plates at the male buckle structure and the female buckle structure may abut each other or have a gap therebetween.
[0019] As an optional solution, a waterproof layer is coated on the abutment portion or the spacing portion between the inner and outer layers of the metal plates at the male buckle structure and the female buckle structure.
[0020] As an optional solution, the metal plate is an aluminum plate or a galvanized steel plate.
[0021] As an optional solution, the sandwich layer is fireproof rock wool.
[0022] Another object of the embodiments of the present application is to provide a corner curtain wall that is inclined and whose side surfaces can fit tightly with the side surfaces of a horizontal or vertical curtain wall.
[0023] To achieve this goal, the present invention adopts the following technical solutions:
[0024] A corner curtain wall comprising
[0025] A plurality of corner sandwich panels are arranged in sequence, wherein the corner sandwich panels are the above-mentioned corner sandwich panels.
[0026] The technical solution provided by the embodiment of the present application is to set one of the upper and lower sides of the corner sandwich panel as a male buckle structure, and the other as a female buckle structure that cooperates with the male buckle structure. The upper and lower corner sandwich panels are positioned by the cooperation of the male buckle structure and the female buckle structure. The left and right sides of the corner sandwich panel are provided with inclined side surfaces that are inclined toward each other, and the angles between the two inclined side surfaces and the vertical plane are respectively a first angle and a second angle, and the sum of the first angle and the second angle is 90°. When the corner sandwich panel is in the installation position, the front and rear surfaces of the corner sandwich panel are inclined, but the left and right inclined side surfaces of the corner sandwich panel are parallel to the horizontal plane or the vertical plane, respectively, so that they can be aligned and fitted with the side edges of ordinary sandwich panels without filling the corner gap, which not only speeds up the construction progress but also saves gap filling materials and is low in cost.

[0035] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present application and are not intended to limit the present application. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions of the present application, not all of the structures.
[0036] In the description of this application, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.
[0037] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.
[0038] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meanings.
[0039] The embodiment of the present application provides a corner curtain wall, such as Figure 1 As shown, the corner curtain wall 200 is located between two perpendicular ordinary curtain walls 100 and is in an inclined state. The two side surfaces of the corner curtain wall 200 along the left and right directions are parallel to the XZ plane or the YZ plane, respectively, so that it can be closely connected with the side surfaces of the corresponding ordinary curtain walls 100 without any corner gaps, and thus there is no need for gap filling. This not only saves materials and reduces costs, but also speeds up construction progress and improves thermal insulation and waterproofing.
[0040] Specifically, the corner curtain wall 200 includes a corner keel and a plurality of corner sandwich panels sequentially laid on the corner keel. Figures 2 to 4 As shown, one of the upper and lower sides of the corner sandwich panel has a male buckle structure 1, and the other has a female buckle structure 2 that cooperates with the male buckle structure 1. The male buckle structure 1 of one of the two adjacent sandwich panels cooperates with the female buckle structure 2 of the other to position the two sandwich panels and ensure the flatness of the outer surface of the corner curtain wall. The left and right sides of the corner sandwich panel are provided with inclined side surfaces that are inclined toward each other. The angles between the two inclined side surfaces and the vertical plane are respectively a first angle α and a second angle β, and the sum of the first angle and the second angle is 90°. Since the original relationship between the two adjacent curtain walls is perpendicular, the two curtain walls are at 90°. Therefore, when a corner curtain wall is installed between the two curtain walls, the side angles on both sides of the corner curtain wall should also be 90° to match the side angles of the curtain wall on the corresponding side. The size of the first angle and the second angle can be set as needed to achieve different chamfer angles of the corner curtain wall.
[0041] In some embodiments of the present application, Figures 2 and 3 As shown, the first angle and the second angle can be the same. In this case, the corner curtain wall 200 is chamfered at 45°. The first angle and the second angle can also be set to be different as needed, as long as the preset angle of the corner curtain wall 200 is met.
[0042] The corner sandwich panel includes two inner and outer metal plates 10 and a sandwich layer 20 between the two metal plates 10. The sandwich layer 20 has good thermal insulation performance, and the inner and outer metal plates 10 can isolate the sandwich layer 20 from the outside world, preventing the outside world from affecting the sandwich layer 20 and ensuring the performance of the sandwich layer 20.
[0043] In some embodiments of the present application, Figures 1 and 2 As shown, the two metal plates 10 are aligned with the center of the sandwich layer 20. The left and right sides of the sandwich layer 20 are oblique side surfaces. The outer metal plate 10 is longer in the left-right direction than the outer side surface of the sandwich layer 20. The portion of the outer metal plate 10 that is longer than the sandwich layer 20 is bent toward the sandwich layer 20 to form a hemming structure that abuts the sandwich layer 20. This not only strengthens the structure but also prevents the sandwich layer 20 from leaking out and being affected by the external environment. It is understandable that the side edges of the corner sandwich panel are bonded to the side edges of the corresponding ordinary sandwich panel using adhesive. If the adhesive is exposed to the outside world for a long time, it will be affected by the outside world and its bonding performance will be affected. The hemming provided on the outside of the side of the corner sandwich panel can prevent the adhesive from failing on the outside part of the adhesive. If external liquid enters through the gap between the corner sandwich panel and the ordinary sandwich panel, the hemming can prevent the liquid from affecting the sandwich panel.
[0044] In some embodiments of the present application, Figures 2 and 3 As shown, the inner and outer metal plates 10 are longer in the vertical direction than the sandwich layer 20, and the portion longer than the sandwich layer 20 is bent toward the sandwich layer 20 to form a hemming structure that abuts the sandwich layer 20. The strength of the male and female connector structures is reinforced to ensure the connection strength of two adjacent corner sandwich panels.
[0045] In some embodiments of the present application, the edges of the inner and outer metal plates 10 at the male and female snap structures 1 and 2 may abut or be spaced apart. Because the female snap structure 2 and the male snap structure 1 mate with each other, a spacer is provided in the center of the spacer. This spacer does not affect the protection of the sandwich panel, but also saves material and costs on the inner and outer metal plates 10.
[0046] Furthermore, in some embodiments of the present application, a waterproof layer is coated at the abutment points or the spacing points between the inner and outer metal plates 10 of the male buckle structure 1 and the female buckle structure 2 to ensure waterproof performance and prevent external liquids from entering and damaging the sandwich layer.
[0047] In some embodiments of the present application, the metal plate 10 may be an aluminum plate, which has good anti-oxidation effect and is lightweight. Of course, the metal plate 10 may also be a galvanized steel plate, which also has good anti-oxidation performance and is low in cost.
[0048] In some embodiments of the present application, the sandwich layer is fireproof rock wool, so that the corner sandwich panel is not only fireproof but also has a good thermal insulation effect.
[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
