Abstract
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 transforms traditional construction work into a model of factory prefabrication and on-site assembly. Components involved in the construction, such as flooring, walls, ceilings, doors and windows, as well as furniture and equipment, are standardized and industrialized in factories, and then transported to the construction site for assembly and installation. This method offers advantages such as minimal construction errors, high efficiency, and environmental friendliness, meeting people's pursuit of an environmentally friendly, energy-saving, efficient, and convenient lifestyle. In this modern prefabricated construction method, the construction at external corners is particularly challenging, requiring precise connections between two wall panels.
[0003] In the prior art, Chinese patent CN204098447U discloses a corner strip for an integrated thermal insulation and decoration system. It consists of an inner right angle, an outer right angle, and a web connecting the inner and outer right angles, forming a symmetrical structure along the central axis of the web. In use, the corner strip needs to be installed and fixed to the outer corner of the building's foundation wall. Then, one side of the integrated thermal insulation and decoration panel is cut at a 45-degree angle and installed using normal construction methods, with the 45-degree cut edge tucked into the gap between the inner and outer right angles of the corner strip. The complexity of this cutting process increases the difficulty and time cost of construction, and is prone to errors, thus affecting the overall decoration effect and construction progress. Therefore, it is not suitable for efficient prefabricated decoration processes. Utility Model Content

[0040] 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.
[0041] An embodiment of this application provides a corner structure, including: a corner piece, comprising a first surface, a second surface, and a corner face, wherein the first surface and the second surface are adjacent surfaces, and the two ends of the corner face are respectively connected to the first surface and the second surface; wherein, elastic elements are provided on both the first surface and the second surface, and the elastic elements protrude from the first surface and the second surface; the corner face includes at least one plane, and when the corner face includes two or more planes connected in sequence, the corner face is a concave surface.
[0042] According to an embodiment of this application, the external corner structure includes an elastic element, and one end of the wall panel to be installed has a groove. During wall panel installation, the elastic element is embedded in the groove, thereby completing 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 panel 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 panel to be installed provided by this application 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 development trends in the decoration industry.
[0043] Figure 1 The schematic diagram illustrates the structure of the external corner structure according to an embodiment of this application.
[0044] like Figure 1 As shown, the corner piece includes a first surface 21, a second surface 22, and a corner face 23. The first surface 21 and the second surface 22 are adjacent surfaces, and the two ends of the corner face 23 are connected to the first surface 21 and the second surface 22, respectively.
[0045] According to the embodiments of this application, both the first surface 21 and the second surface 22 are planar. When the wall panel is installed, the first surface 21 and the second surface 22 are in contact with the end faces of two adjacent wall panels respectively. Waterproof strips (not shown in the figure) can be provided on the first surface 21 and the second surface 22. When the wall panel is used in an environment with high waterproof requirements, the waterproof strips can increase the sealing between the corner structure and the wall panel, achieve a certain waterproof effect, and will not affect its thickness and aesthetics.
[0046] According to embodiments of this application, the external corner surface 23 includes at least one plane. In an optional embodiment, the external corner surface 23 includes a plane, in which case the cross-section of the external corner piece is triangular. In another optional embodiment, referring to... Figure 1 As shown, the external corner surface 23 includes two or more planes connected in sequence, and the external corner surface 23 is a concave surface. Preferably, the external corner surface 23 is an axisymmetric figure, and its axis of symmetry coincides with the extension line of the web 70. The specific shape of the external corner surface 23 can be designed according to actual needs, and is not limited here.
[0047] According to an embodiment of this application, during wall panel installation, the external corner surface 23 is located at the external corner. When the wall panel is subjected to external impact or bears its own load, the external corner surface 23 can disperse and transmit stress, preventing stress concentration at the external corner. This reduces the risk of cracking or breakage of the wall panel at the external corner, improves the overall structural stability and mechanical properties of the wall panel, and extends its service life. Furthermore, the design of the external corner surface 23 can reduce the impact severity when a user accidentally bumps into the external corner, protecting user safety. It also enhances the aesthetics and artistry of the space, meeting people's personalized and diverse needs for interior decoration.
[0048] According to an embodiment of this application, a decorative layer (not shown in the figures) is provided on the external corner surface 23. On the one hand, the decorative layer can decorate the external corner, enhance the aesthetics of the external corner structure, and has a simple structure and is easy to install; on the other hand, the decorative layer can improve the weather resistance of the external corner structure, prevent the external corner from deforming, and thus improve the service life of the external corner. As an example, the decorative layer can be a decorative film, such as polyvinyl chloride (PVC) coated cloth or PVDF (polyvinylidene fluoride) film, or it can be a decorative paper.
[0049] According to an embodiment of this application, the external angle formed by the two wall panels is a right angle, therefore, as Figure 1 As shown, the first surface 21 and the second surface 22 are perpendicularly connected. It should be noted that, in this embodiment, "perpendicular" means that the included angle between them is 90°. , This is the error angle, which can be 0°, 5°, 10°, etc., and its specific value can be set according to the actual situation.
[0050] In an optional embodiment, the corner bracket may further include a first end face 24 and a second end face 25, wherein the first end face 24 is used to connect one end of the first surface 21 and the corner face 23, and the second end face 25 is used to connect the other end of the second surface 22 and the corner face 23. Preferably, the first end face 24 is perpendicularly connected to the first surface 21, and the second end face 25 is perpendicularly connected to the second surface 22, so that after the wall panel is installed, the surface of the wall panel is flush with the first end face 24 and the second end face 25, which helps to improve the aesthetics of the wall.
[0051] According to the embodiments of this application, the external corner piece 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 external corner structure.
[0052] like Figure 1 As shown, the external corner structure provided in this embodiment also includes a first connector 31 and a second connector 32, wherein the first connector 31 is parallel to the first surface 21, and the second connector 32 is parallel to the second surface 22; one end face of the first connector 31 is connected to one end face of the second connector 32. In an optional embodiment, the first surface 21 is perpendicular to the second surface 22, therefore, the first connector 31 is perpendicular to the second connector 32.
[0053] According to an embodiment of this application, the area between the first connector 31 and the second connector 32 is a connection area 100, and the opening direction of the connection area 100 is opposite to the orientation of the external corner surface 23. When installing the wall panel, the first connector 31 and the second connector 32 are respectively attached to two adjacent surfaces of the wall, that is, the connection area 100 is used to accommodate the wall.
[0054] According to an embodiment of this application, both the first connector 31 and the second connector 32 are provided with countersunk nail grooves 30, the openings of which are away from the connection area 100. The countersunk nail grooves 30 are used to install fasteners to fix the external corner structure to the wall.
[0055] 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.
[0056] According to an embodiment of this application, a first support edge 51 is provided at the end of the first connector 31 away from the web plate 70. The first support edge 51 is perpendicularly connected to the first connector 31 and extends from the first connector 31 toward the connection area 100. This creates a space between the first support edge 51 and the side of the countersunk nail groove 30, which strengthens the rigidity of the first connector 31 and ensures the stability of the overall external corner structure after installation.
[0057] According to an embodiment of this application, a second support edge 52 is provided at the end of the second connector 32 away from the web plate 70. The second support edge 52 is perpendicularly connected to the second connector 32 and extends from the second connector 32 toward the connection area 100. This creates a space between the second support edge 52 and the side of the countersunk nail groove 30, which strengthens the firmness of the second connector 32 and ensures the stability of the overall external corner structure after installation.
[0058] like Figure 1 As shown, the external corner structure provided in this embodiment also includes a web plate 70. One end of the web plate 70 is connected to the first surface 21 and the second surface 22, and the other end is connected to the first connector 31 and the second connector 32. According to the embodiment of this application, the extension line of the web plate 70 coincides with the angle bisector of the angle between the first surface 21 and the second surface 22, and the two sides of the web plate 70 are respectively used to install two adjacent wall panels.
[0059] like Figure 1 As shown, elastic elements are provided on both the first surface 21 and the second surface 22. The elastic elements include a first elastic element 11 and a second elastic element 12, wherein the first elastic element 11 protrudes from the first surface 21 and the second elastic element 12 protrudes from the second surface 22. When installing the wall panel, the first elastic element 11 and the second elastic element 12 are inserted into the wall panel to connect with it.
[0060] According to embodiments of this application, the first surface 21 is arranged parallel to the second elastic member 12, and the second surface 22 is arranged parallel to the first elastic member 11. In an optional embodiment, the external angle formed by the two wall panels is a right angle; therefore, as... Figure 1As shown, the first elastic element 11 is perpendicular to the first surface 21, and the second elastic element 12 is perpendicular to the second surface 22.
[0061] In an optional embodiment, the first elastic element 11 is located on the perpendicular bisector between the second connector 32 and the first end face 24, and the second elastic element 12 is located on the perpendicular bisector between the first connector 31 and the second end face 25. After the wall panel is installed, the external corner structure can be subjected to uniform force, thereby enhancing the stability and reliability of the overall structure.
[0062] According to the embodiments of this application, the first elastic element 11 and the second elastic element 12 are both made of elastic materials, such as rubber, polyurethane elastomer, silicone rubber, etc. Since the first elastic element 11 and the second elastic element 12 are made of elastic materials, when the wall panel is installed or disassembled, the first elastic element 11 and the second elastic element 12 deform under 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 external corner line, which reduces the construction difficulty, improves the construction accuracy, and is suitable for efficient prefabricated decoration process.
[0063] like Figure 1 As shown, the sides of the first elastic element 11 and the second elastic element 12 away from the connecting area 100 are both convex arc-shaped surfaces, while the sides near the connecting area 100 are both flat surfaces. Furthermore, the dimensions of the first elastic element 11 and the second elastic element 12 gradually decrease from the end near the corner piece to the end away from the corner piece. This design facilitates wall panel installation and enhances the stability of the wall panel after installation. Taking the first elastic element 11 as an example, when installing the wall panel, it can be installed from the outside inwards towards the connecting area 100. The first elastic element 11 deforms under the force of the wall panel, and the convex arc-shaped surface reduces the resistance generated by the first elastic element 11 on the wall panel, thus facilitating wall panel installation. After the wall panel is installed, since the side of the first elastic element 11 near the connecting area 100 is flat, this flat surface generates greater resistance to the wall panel, thereby preventing the wall panel from falling off.
[0064] According to the embodiments of this application, shock-absorbing pads 60 are provided on the side of the first elastic member 11 and the second elastic member 12 near the connection area 100, which are used to fill the gap between the wall panel and the first elastic member 11 and the second elastic member 12, prevent the corner structure from shaking with the wall panel, and ensure the stability of the overall corner structure after installation.
[0065] 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.
[0066] Figure 2 A schematic diagram of the structure of a wall panel system according to an embodiment of this application is shown.
[0067] 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 corner piece, a first elastic member, and a second elastic member. For details, please refer to... Figure 1 As described above, it will not be repeated here.
[0068] 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 groove 401, which are used to accommodate the first elastic member 11 and the second elastic member 12 in the external corner structure, respectively.
[0069] According to an embodiment of this application, the first elastic element 11 and the second elastic element 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:
[0070] 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.
[0071] 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 first connector 31 and the second connector 32 are in contact with two adjacent surfaces of the wall 300, respectively; the fixing member 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 fixing member 500 can be a screw, pneumatic nail, or other component that can provide a fixing function.
[0072] 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.
[0073] 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 elastic element 11 and the second elastic element 12 are respectively inserted into the slots 401 of the first wall panel 410 and the second wall panel 420 to complete the installation.
[0074] 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.

Although various embodiments have been described above, this does not mean that the measures in the various embodiments cannot be used advantageously in combination. The scope of this application is defined by the appended claims and their equivalents.
