Description

Technical Field

[0001] This application relates to the field of building technology, and more specifically, to a corner structure and wall panel system. Background Technology

[0002] Prefabricated construction is a process of reliably assembling industrially produced components on-site using dry construction methods. It features standardized design, industrialized production, prefabricated construction, and information-based collaboration. Through modular design and factory production, it improves quality and efficiency while reducing on-site wet work and waste pollution. Prefabricated construction facilitates later maintenance and replacement, meets energy-saving and environmental protection requirements, and represents the future trend of the construction industry.

[0003] In the field of construction, the external corner is a key concept, referring to the protruding corner of a wall, such as the four protruding corners of a building's exterior, as well as the angle between door and window openings and the wall. In prefabricated construction, a modern construction method, the construction of external corners is particularly unique, requiring precise connection between two wall panels.

[0004] The conventional connection method involves processing the two wall panels at the external corner by cutting them at a 45° angle along the corner line, and then directly connecting them. This method requires a high level of skill from the construction workers, and the cutting work must be performed by skilled technicians. However, in prefabricated decoration projects, there are often many construction steps and a large number of construction workers, making it difficult to ensure that every worker responsible for cutting has sufficient proficiency. Moreover, the complexity of this cutting process itself increases the difficulty and time cost of construction, and is prone to errors, which in turn affect the overall decoration effect and construction progress. Therefore, it is not suitable for the efficient prefabricated decoration process.

[0005] To improve the efficiency and quality of corner treatment in prefabricated decoration, it is necessary to further explore simpler, more reliable and easier-to-operate connection technologies and processes to adapt to the current rapid and precise development needs of prefabricated decoration.

[0035] The embodiments of this application will now be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of this application. In the following detailed description, numerous specific details are set forth to provide a thorough understanding of the embodiments of this application for ease of explanation. However, it will be apparent that one or more embodiments may be implemented without these specific details. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concepts of this application.

[0036] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0037] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.

[0038] When using expressions such as "at least one of A, B and C", they should generally be interpreted in accordance with the meaning that is commonly understood by those skilled in the art (e.g., "a system having at least one of A, B and C" should include, but is not limited to, a system having A alone, a system having B alone, a system having C alone, a system having A and B, a system having A and C, a system having B and C, and / or a system having A, B and C, etc.).

[0039] In this technology, two wall panels intended for installation at the external corner of the wall need to be cut to a specific angle to achieve the desired installation. On one hand, this requires a high level of skill from the construction workers, making the installation difficult and time-consuming. On the other hand, this installation method is not suitable for efficient prefabricated construction processes and does not align with the future development trend of the decoration industry.

[0040] An embodiment of this application provides a corner structure, comprising: a support member, including a first support plate, a second support plate, and a corner plate connected in sequence, wherein the first support plate and the second support plate form an included angle; a first connector, mounted on the first support plate, the first connector having a first fixed end and a first elastic end, the first fixed end being fixed in the first support plate, and the first elastic end extending from the first fixed end in a direction away from the support member; and a second connector, mounted on the second support plate, the second connector having a second fixed end and a second elastic end, the second fixed end being fixed in the second support plate, and the second elastic end extending from the second fixed end in a direction away from the support member.

[0041] According to an embodiment of this application, the external corner structure includes a first connector and a second connector. The first and second connectors are used to install two adjacent wall panels. One end of each wall panel has a groove, and both the first and second connectors have elastic ends that are embedded in the grooves to complete the wall panel installation. Using the external corner structure provided by this application, precise connection of wall panels can be achieved without cutting the wall panels into a 45° angle along the external corner line, reducing construction difficulty and shortening construction time. Furthermore, both the external corner structure and the wall panels to be installed can be industrially produced in a factory, requiring only simple installation on-site. This is suitable for efficient prefabricated decoration processes and aligns with future trends in the decoration industry.

[0042] Figure 1 The schematic diagram illustrates the structure of the external corner structure according to an embodiment of this application.

[0043] like Figure 1 As shown, the support includes a first support plate 21, a second support plate 22, and a corner plate connected in a clockwise direction.

[0044] According to an embodiment of this application, during wall panel installation, the first support plate 21 and the second support plate 22 respectively contact the end faces of two adjacent wall panels. In an optional embodiment, a waterproof strip (not shown in the figure) can be provided on the surfaces of the first support plate 21 and the second support plate 22 that contact the wall panel. When the wall panel is used in an environment with high waterproof requirements, the waterproof strip can increase the sealing between the corner structure and the wall panel, achieving a certain waterproof effect without affecting its thickness or aesthetics.

[0045] According to an embodiment of this application, the corner plate includes a first corner plate 71 and a second corner plate 72, wherein the first corner plate 71 is connected to a first support plate 21, and the second corner plate 72 is connected to a second support plate 22. In an optional embodiment, the connection point between the first corner plate 71 and the second corner plate 72 is a rounded corner structure. The rounded corner structure can reduce the impact severity when a user accidentally collides with the corner, thus protecting the user's safety.

[0046] According to embodiments of this application, the corner plate can be made of metal material. Metal material has good ductility, is easy to grind and manufacture, and has good rigidity, which can prevent deformation of the corner plate. In an optional embodiment, the outer surface of the corner plate can be treated with different processes such as film application and painting, depending on actual needs.

[0047] In one optional embodiment, the external angle formed by the two wall panels is a right angle, therefore, as Figure 1 As shown, the first corner plate 71 is perpendicular to the second corner plate 72, the first support plate 21 is perpendicular to the second support plate 22, the first support plate 21 is perpendicular to the first corner plate 71, and the second support plate 22 is perpendicular to the second corner plate 72. It should be noted that, in this embodiment, "perpendicular" refers to an angle of 90° between the two. , This is the error angle, which can be 0°, 5°, 10°, etc., and its specific value can be set according to the actual situation.

[0048] According to an embodiment of this application, the support further includes a third support plate 23 and a fourth support plate 24. The third support plate 23 is located on the same plane as the first support plate 21 and is connected to the second support plate 22; the fourth support plate 24 is located on the same plane as the second support plate 22 and is connected to the first support plate 21. In this embodiment, the first support plate 21 and the second support plate 22 are vertically connected. Therefore, the first support plate 21, the second support plate 22, the third support plate 23, and the fourth support plate 24 form a cross-shaped structure. The area between the third support plate 23 and the fourth support plate 24 is the installation area 100. When installing the wall panel, the third support plate 23 and the fourth support plate 24 are respectively attached to two adjacent surfaces of the wall, that is, the installation area 100 is used to accommodate the wall.

[0049] According to an embodiment of this application, both the third support plate 23 and the fourth support plate 24 are provided with countersunk nail grooves 30, the openings of which are opposite to the mounting area 100. The countersunk nail grooves 30 are used to install fasteners to fix the external corner structure to the wall.

[0050] According to an embodiment of this application, the countersunk pin groove 30 has a positioning groove 40, which coincides with the axis of symmetry of the countersunk pin groove 30, that is, it is located at the center of the countersunk pin groove 30, and is used to position the fastener during installation.

[0051] According to an embodiment of this application, a first support edge 51 is provided at the end of the third support plate 23 away from the support member. The first support edge 51 is perpendicularly connected to the third support plate 23 and extends from the third support plate 23 toward the mounting area 100. This creates a space between the first support edge 51 and the side of the countersunk nail groove 30, which strengthens the stability of the third support plate 23 and ensures the stability of the overall external corner structure after installation.

[0052] According to an embodiment of this application, a second support edge 52 is provided at the end of the fourth support plate 24 away from the support member. The second support edge 52 is perpendicularly connected to the fourth support plate 24 and extends from the fourth support plate 24 toward the mounting area 100. This creates a space between the second support edge 52 and the side of the countersunk nail groove 30, which strengthens the stability of the fourth support plate 24 and ensures the stability of the overall external corner structure after installation.

[0053] like Figure 1 As shown, the first connector 11 has a first fixed end 111 and a first elastic end 112, which are arranged perpendicularly. The first fixed end 111 is fixed in the first support plate 21, and the first elastic end 112 extends from the first fixed end 111 in a direction away from the support member. Figure 1 (Extended in the X-axis direction shown). When installing the wall panel, the first connector 11 is inserted into the wall panel to connect with it.

[0054] like Figure 1 As shown, the second connector 12 has a second fixed end 121 and a second elastic end 122, which are arranged perpendicularly. The second fixed end 121 is fixed in the second support plate 22, and the second elastic end 122 extends from the second fixed end 121 in a direction away from the support member. Figure 1 (Extended along the Y-axis direction as shown). During wall panel installation, the second connector 12 is inserted into the wall panel to connect with it.

[0055] According to an embodiment of this application, the first connector 11 is mounted on the first support plate 21, and the second connector 12 is mounted on the second support plate 22. In an optional embodiment, the first support plate 21 is arranged parallel to the second elastic end 122, and the second support plate 22 is arranged parallel to the first elastic end 112. In another optional embodiment, the external angle formed by the two wall panels is a right angle; therefore, as... Figure 1 As shown, the first elastic end 112 is perpendicular to the first support plate 21, and the second elastic end 122 is perpendicular to the second support plate 22.

[0056] According to the embodiments of this application, the first elastic end 112 and the second elastic end 122 are both made of elastic materials, such as rubber, polyurethane elastomer, silicone rubber, etc. Since the first elastic end 112 and the second elastic end 122 are made of elastic materials, when the wall panel is installed or disassembled, the first elastic end 112 and the second elastic end 122 are deformed by force, which facilitates the installation and disassembly of the wall panel. Therefore, it is not necessary to cut the wall panel into a shape with a 45° angle along the direction of the external corner, which reduces the construction difficulty, improves the construction accuracy, and is suitable for efficient prefabricated decoration process.

[0057] like Figure 1As shown, the sides of the first elastic end 112 and the second elastic end 122 away from the installation area 100 are both convex arc-shaped surfaces, while the sides close to the installation area 100 are both flat surfaces. This design facilitates wall panel installation and enhances the stability of the wall panel after installation. Taking the first elastic end 112 as an example, when installing the wall panel, it can be installed from the outside inwards towards the installation area 100. The first elastic end 112 deforms under the force of the wall panel, and the convex arc-shaped surface reduces the resistance generated by the first elastic end 112 on the wall panel, thus facilitating wall panel installation. After the wall panel is installed, since the side of the first elastic end 112 close to the installation area 100 is flat, the flat surface generates greater resistance to the wall panel, thus preventing the wall panel from falling off.

[0058] According to the embodiments of this application, shock-absorbing pads 60 are provided on the side of the first elastic end 112 and the second elastic end 122 near the installation area 100, which are used to fill the gap between the wall panel and the first plug-in 11 and the second plug-in 12, prevent the corner structure from shaking with the wall panel, and ensure the stability of the overall corner structure after installation.

[0059] Based on the aforementioned external corner structure, this application also provides a wall panel system. The following will be combined with... Figure 2 The wall panel system is described in detail.

[0060] Figure 2 A schematic diagram of the structure of a wall panel system according to an embodiment of this application is shown.

[0061] like Figure 2 As shown, the wall panel system provided in this embodiment includes a first wall panel 410, a second wall panel 420, and a corner structure. The corner structure includes a support member, a first connector, and a second connector. For details, please refer to... Figure 1 As described above, it will not be repeated here.

[0062] According to an embodiment of this application, the ends of the first wall panel 410 and the second wall panel 420 each have a recessed slot 401, which are used to accommodate the first connector 11 and the second connector 12 in the external corner structure, respectively.

[0063] According to an embodiment of this application, the first connector 11 and the second connector 12 in the corner structure are respectively inserted into the slot 401, so that the first wall panel 410 and the second wall panel 420 are connected through the corner structure. The specific installation method is as follows:

[0064] First, the leveling keel 200 is installed on the wall 300 to form a leveling structure on the wall 300, so as to install the first wall panel 410, the second wall panel 420 and the external corner structure.

[0065] Next, the corner structure is installed at the external corner of the wall 300. Specifically, the corner structure is placed at the external corner of the wall 300, so that the third support plate 23 and the fourth support plate 24 are in contact with two adjacent surfaces of the wall 300, respectively; the fastener 500 is aligned with the positioning groove 40 and passes through the positioning groove 40 and the leveling joist 200 from the outside in, thereby fixing the corner structure to the wall 300. As an example, the fastener 500 can be a screw, pneumatic nail, or other component that can provide a fixing function.

[0066] Next, a first wall panel 410 and a second wall panel 420 are provided, and adhesive, such as structural adhesive, expanding foam, or PVC adhesive, is applied to the mounting surface of the wall panels to facilitate subsequent bonding with the leveling keel 200. According to an embodiment of this application, the end face of the wall panel between the slot 401 and the mounting surface is set as a slope, and this slope forms an angle greater than 90° with the mounting surface. When installing the first wall panel 410 and the second wall panel 420, this slope cooperates with the protruding arc-shaped surface of the first connector 11 or the second connector 12, which can reduce the resistance generated by the first connector 11 or the second connector 12 on the first wall panel 410 and the second wall panel 420.

[0067] Finally, the mounting surface of the wall panel is oriented towards the wall 300, so that the mounting surface of the wall panel is bonded to the wall 300. The first connector 11 and the second connector 12 are respectively inserted into the slots 401 of the first wall panel 410 and the second wall panel 420 to complete the installation.

[0068] The external corner structure provided in this embodiment is suitable for interior decoration. All components are industrially produced in the factory, and only simple installation is required on the decoration site. No skilled technicians are needed on site, and not much construction time is required, which realizes rapid construction and avoids the dirty situation of traditional decoration work sites.
