Description

Technical Field

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

[0002] Modular wall panels, also known as prefabricated decorative panels or prefabricated wall coverings, are a type of building material that requires no priming and can be installed directly. Their water resistance is far superior to traditional wallpaper, which is prone to mold and peeling when exposed to moisture, while these panels offer greater dimensional stability and strength. Compared to oil-based paints, modular wall panels release no benzene compounds throughout the entire process, allowing for quick occupancy after completion.

[0003] Typically, a corner structure is added at the location where an inside corner is formed to connect the wall panel. For example, patent application CN222810348U, entitled "A Quick-Installation Inside Corner Connection Structure," claims protection for a quick-installation inside corner connection structure, including an edge-sealing seat, a first connecting seat, and a second connecting seat. The first and second connecting seats are used to connect with the panel. The edge-sealing seat is respectively provided with a first pin and a second pin. The first pin is connected to the first connecting seat, and the second pin is connected to the second connecting seat.

[0004] The inventors discovered that different sized inside corners require different sized inside corner structures to fit the inside corner and complete the wall panel installation. However, usually each set of inside corner structures is adapted to the corresponding size inside corner, and if the inside corner size changes, the entire set of components needs to be replaced.

[0029] Figure 1 A schematic diagram of a concave corner structure 100 including a first-specification target arc-shaped structural portion 130 is shown according to an embodiment of this application.

[0030] In some embodiments, the concave corner structure 100 includes a first transition portion 110, a second transition portion 120, and a target arc-shaped structure portion 130. The first transition portion 110 includes a first transition end 111, which is provided with a first slot 112; the second transition portion 120 includes a second transition end 121, which is provided with a second slot 122; the target arc-shaped structure portion 130 is located between the first transition portion 110 and the second transition portion 120, and the target arc-shaped structure portion 130 includes an arc-shaped member 131, a first protrusion 132, and a second protrusion 133. The first protrusion 132 is located at the first end of the arc-shaped member 131, and the first protrusion 132 is configured to engage with the first slot 112; the second protrusion 133 is located at the second end of the arc-shaped member 131, and the second protrusion 133 is configured to engage with the second slot 122, with the first end of the arc-shaped member 131 opposite to its second end; wherein, the target arc-shaped structure portion 130 is predetermined from a plurality of candidate arc-shaped structure portions, the plurality of candidate arc-shaped structure portions having at least different specifications, and all of them being adapted and connected to the first adapter portion 110 and the second adapter portion 120.

[0031] Exemplarily, the transition portion includes components that serve as a connection or transition. A first transition portion 110 connects to both the target arc-shaped structure portion 130 and the wall panel, and a second transition portion 120 is similar to the first transition portion 110. A transition end is the end of the transition portion used to connect to other components. The first transition portion 110 may be hollow internally, and the first transition end 111 is located on one edge of the plate. The first slot 112 may be a rectangular slot, a spherical slot, etc., formed on the first transition end 111 by injection molding or stamping, and the size of the slot is adapted to the first protrusion 132. The second transition portion 120 is similar to the first transition portion 110.

[0032] The arc-shaped component 131 includes an arc-shaped part. The target arc-shaped structural portion 130 serves to connect the first transition portion 110 and the second transition portion 120, and to form an arc-shaped transition at the inner corner. The target arc-shaped structural portion 130 may include a first structural portion 134 and a second structural portion 135. The first structural portion 134 and the second structural portion 135 are connected by a transition plate. The first structural portion 134 includes a first outer plate and a first portion of the arc-shaped component 131 divided by the transition plate; the second structural portion 135 includes a second outer plate and a second portion of the arc-shaped component 131 divided by the transition plate. Here, the side closer to the interior space during assembly is referred to as the inner side, and correspondingly, the side closer to the wall is referred to as the outer side.

[0033] The first structural part 134 and the second structural part 135 are arranged perpendicularly to mate with the inside corner of the wall. As shown in the figure, the first structural part 134 extends vertically, and the second structural part 135 extends horizontally. The end of the first structural part 134 away from the transition plate has a first protrusion 132, i.e., the upper end of the first structural part 134 has a first protrusion 132. The end of the second structural part 135 away from the transition plate has a second protrusion 133, i.e., the right end of the second structural part 135 has a second protrusion 133, and the opening of the second protrusion 133 faces to the right. As such, it can be understood that the first protrusion 132 and the second protrusion 133 are perpendicular. In actual assembly, the inside corner structure 100 is located at the inside corner of the wall, and its first protrusion 132 and second protrusion 133 can be inserted and mated with the first slot 112 and the second slot 122 respectively, i.e., a snap-fit ​​configuration.

[0034] Figure 2 A schematic diagram of a concave corner structure 100 including a second-specification target arc-shaped structural portion 230 is shown according to another embodiment of this application. Figure 2 The target arc-shaped structure 230, which is selected according to another specification, includes an arc-shaped member 231, a first protrusion 232 and a second protrusion 233; the first protrusion 232 is located at the first end of the arc-shaped member 231 and is configured to engage with the first slot 112; the second protrusion 233 is located at the second end of the arc-shaped member 231 and is configured to engage with the second slot 122, with the first end of the arc-shaped member 231 opposite to its second end.

[0035] Reference Figure 1 The target arc-shaped structure 130 of Embodiment 1 and Figure 2 The target arc-shaped structural part 230 in Embodiment 2 allows for the selection of a suitable target arc-shaped structural part based on actual needs by pre-preparing multiple candidate arc-shaped structural parts of different specifications, thereby improving versatility and adaptability. For example, in interior corner decoration of different sizes, a suitable target arc-shaped structural part can be selected from multiple candidate arc-shaped structural parts of different radii, thicknesses, and other specifications.

[0036] Except for Figure 1 and Figure 2 In addition to comparing the structures shown, the relevant statements in this application are based on... Figure 1 The structure and reference numerals shown in the figures are examples.

[0037] In some embodiments, the plurality of candidate arcuate structural components having at least different specifications includes at least two arcuate components with different arcuate radii. Different internal corner space sizes, design styles, etc., may require arcuate components with different degrees of curvature to meet diverse design requirements.

[0038] For example, the adapter may refer to the end of the first protrusion 132 of multiple candidate arc-shaped structural parts of different specifications along... Figure 1 , Figure 2 The length in the left-right direction is less than or equal to the length of the first adapter end 111, and the ends where the second protrusions 133 of the multiple candidate arc-shaped structural parts of different specifications are located are along... Figure 1 , Figure 2 The length in the vertical direction is less than or equal to the length of the second adapter end 121. One or more first slots 112 are provided at the first adapter end 111 to engage the first protrusion 132, and one or more second slots 122 are provided at the second adapter end 121 to engage the first protrusion 132.

[0039] According to the embodiments of this application, the target arc-shaped structure 130 is firmly connected to the first adapter 110 and the second adapter 120 by the snap-fit ​​method of the first protrusion 132 and the first slot 112, and the second protrusion 133 and the second slot 122, which can withstand a certain external force and is not easy to fall off. By using the first adapter 110 and the second adapter 120, multiple candidate arc-shaped structures with different specifications can be adapted, which can meet the needs of the inside corner structure 100 in different scenarios, such as the corner of the room of different sizes, and the requirements of different decoration styles for the arc shape.

[0040] In some embodiments, the first card slot 112 includes a plurality of first sub-card slots (not shown in the figure), and the plurality of candidate arc-shaped structural portions are adapted to be connected to the first adapter portion 110, including: any one of the plurality of candidate arc-shaped structural portions includes a first protrusion 132, and has a first sub-card slot in the plurality of first sub-card slots that matches the first protrusion 132.

[0041] For example, the multiple first sub-slots include multiple subdivided slot structures constituting the first slot 112. The first sub-slots can be rectangular, trapezoidal, or other shapes, and their dimensions are designed according to the dimensions of the first protrusion 132 of different candidate arc-shaped structural parts. For example, if the first protrusion 132 of the candidate arc-shaped structural part is rectangular, the first sub-slot is also a rectangle that matches it, and the dimensional tolerance is controlled within a certain range to ensure the stability of the snap-fit. "Matching" means that the slot and the protrusion fit each other in terms of shape and size, and can snap-fit. For example, candidate arc-shaped structural parts of different specifications can be connected to the first adapter 110 by cooperating with different first sub-slots. Regardless of which candidate arc-shaped structural part is selected, it can be adapted and connected by its first protrusion 132 to the appropriate first sub-slot on the first adapter 110. For example, when arc-shaped decorative strips of different curvatures are used as candidate arc-shaped structural parts, the first protrusion 132 of each decorative strip can find a corresponding first sub-slot for snap-fit, improving versatility.

[0042] According to the embodiments of this application, the matching of multiple first sub-slots with different first protrusions 132 can adapt to a variety of candidate arc-shaped structural parts of different specifications, improve the adaptability range of the connection between the first adapter 110 and the candidate arc-shaped structural parts, meet diverse design requirements, and make the entire inside corner structure solution more versatile in different scenarios, reducing the unusability caused by specification mismatch.

[0043] In some embodiments, the second card slot 122 includes a plurality of second sub-card slots, and the plurality of candidate arcuate structural portions are adapted to be connected to the second adapter portion 120, including: any one of the plurality of candidate arcuate structural portions includes a second protrusion 133, and the plurality of second sub-card slots have a second sub-card slot that matches the second protrusion 133.

[0044] For example, the multiple second sub-slots include multiple subdivided slot structures constituting the second slot 122. The second sub-slots can be rectangular, trapezoidal, or other shapes, and their dimensions are designed according to the dimensions of the second protrusions 133 of different candidate arc-shaped structural parts. For example, if the second protrusion 133 of the candidate arc-shaped structural part is rectangular, the second sub-slot is also a matching rectangle, and the dimensional tolerance is controlled within a certain range to ensure the stability of the snap-fit. Matching means that the slot and the protrusion fit each other in terms of shape and size, and can snap-fit. For example, candidate arc-shaped structural parts of different specifications can be connected to the second adapter 120 by cooperating with different second sub-slots. Regardless of which candidate arc-shaped structural part is selected, it can be adapted and connected to the appropriate second sub-slot on the second adapter 120 through its second protrusion 133. For example, when arc-shaped decorative strips of different curvatures are used as candidate arc-shaped structural parts, the second protrusion 133 of each decorative strip can find a corresponding second sub-slot for snap-fit, improving versatility.

[0045] According to the embodiments of this application, the matching of multiple second sub-slots with different second protrusions 133 can adapt to a variety of candidate arc-shaped structural parts of different specifications, improve the adaptability range of the connection between the second adapter 120 and the candidate arc-shaped structural parts, meet diverse design requirements, and make the entire inside corner structure solution more versatile in different scenarios, reducing the unusability caused by specification mismatch.

[0046] In some embodiments, the first adapter end 111 extends a first length in a direction perpendicular to the wall, and any one of the plurality of candidate arcuate structural portions includes: a third adapter end, connected to the first end of the arcuate member, and extending a third length in a direction perpendicular to the wall; the third length of any one of the plurality of candidate arcuate structural portions is less than or equal to the first length.

[0047] For example, the first length refers to the length of the first adapter end 111 starting from the end closest to the wall, along a direction perpendicular to the wall (e.g., Figure 1 or Figure 2The third length is the distance extended (in the left and right directions) from the third transition end of the candidate arc-shaped structure, extending in a direction perpendicular to the wall. For example... Figure 1 The third length of the third transition end 141 of the target arc-shaped structure 130 is equal to the first length of the first transition end 111. For example... Figure 2 The third length of the third transition end 241 of the target arc-shaped structure 230 is less than the first length of the first transition end 111. The first protrusion 132 is disposed on the third transition end 141, or the first protrusion 232 is disposed on the third transition end 241.

[0048] According to embodiments of this application, by defining a first length and a third length, and making the third length less than or equal to the first length, the third connecting end of any one of a plurality of candidate arc-shaped structural parts with different specifications is adapted to the first connecting end, thereby improving versatility.

[0049] In some embodiments, the second adapter end 121 extends a second length in a direction perpendicular to the wall, and any one of the plurality of candidate arcuate structural portions includes: a fourth adapter end, connected to the second end of the arcuate member, and extending a fourth length in a direction perpendicular to the wall; the second length of any one of the plurality of candidate arcuate structural portions is less than or equal to the fourth length.

[0050] For example, the second length refers to the length of the second adapter end 121 starting from the end closest to the wall, along a direction perpendicular to the wall (e.g., Figure 1 or Figure 2 The fourth length is the distance extended (vertically in the vertical direction) from the fourth transition end 142 of the candidate arc-shaped structure, in a direction perpendicular to the wall. For example... Figure 1 The fourth length of the fourth transition end 142 of the target arc-shaped structure 130 is equal to the second length of the second transition end 121. For example... Figure 2 The fourth length of the fourth transition end 242 of the target arc-shaped structure 230 is less than the second length of the second transition end 121. The second protrusion 133 is disposed on the fourth transition end 142, or the second protrusion 233 is disposed on the fourth transition end 242.

[0051] According to embodiments of this application, by defining the second length and the fourth length, and making the fourth length less than or equal to the second length, the fourth connecting end of any one of a plurality of candidate arc-shaped structural parts with different specifications is adapted to the second connecting end, thereby improving versatility.

[0052] In some embodiments, the first adapter 110 includes a first abutment 113, a first fitting 114, a first insertion end 115, and a first adapter end 111. The first abutment 113 is configured to abut against a wall; the first fitting 114 includes a finishing layer, is further away from the wall than the first abutment 113, and is generally parallel to the first abutment 113; the first insertion end 115 includes a first insertion member 1151, configured as a slot for inserting into a wall panel; the first adapter end 111 is generally parallel to the first insertion member 1151; wherein the first abutment 113, the first fitting 114, the first insertion end 115, and the first adapter end 111 are connected end to end to form a cavity.

[0053] Exemplarily, the first abutment 113 is a component in the first adapter 110 that at least partially contacts and abuts against the wall. The first fitting 114 has a decorative layer that faces away from the wall and towards the interior space, serving a decorative function to some extent. The first insertion end 115 includes a first insertion member 1151 for insertion into a wall panel slot to achieve connection. For example, in the wall installation of prefabricated buildings, the first insertion member 1151 of the first insertion end 115 acts like a protruding tenon, which can be inserted into a pre-reserved slot in the wall panel, like a piece of a puzzle inserted into a corresponding groove, to achieve the connection between the first adapter 110 and the wall panel.

[0054] According to the embodiments of this application, the first abutment 113 abuts against the wall and the first plug-in end 115 plugs into the wall panel slot, making the installation process of the first adapter 110 simple and convenient, and able to firmly connect with the wall and wall panel, ensuring the stability of the entire inside corner structure 100, and preventing it from loosening or falling off; the finishing layer of the first decorative part 114 can be selected according to different decoration styles, which can effectively improve the aesthetics of the inside corner and meet the decoration needs of different places; the cavity can be used to hide the wiring, making the indoor wiring neater, and can also be filled with sound insulation, heat insulation and other materials to improve the sound insulation and heat insulation performance of the inside corner, increasing the practicality and functionality of the inside corner structure 100.

[0055] In some embodiments, the second adapter 120 includes a second abutment 123, a second fitting 124, a second insertion end 125, and a second adapter end 121. The second abutment 123 is configured to abut against a wall; the second fitting 124 includes a finishing layer, is further away from the wall than the second abutment 123, and is generally parallel to the second abutment 123; the second insertion end 125 includes a second insertion member 1251, configured as a slot for inserting into a wall panel; the second adapter end 121 is generally parallel to the second insertion member 1251; wherein the second abutment 123, the second fitting 124, the second insertion end 125, and the second adapter end 121 are connected end-to-end to form a cavity.

[0056] Exemplarily, the second abutment 123 is a component in the second adapter 120 that at least partially contacts and abuts against the wall. The second fitting 124 has a decorative layer facing away from the wall and towards the interior space, serving a decorative function to some extent. The second insertion end 125 includes a second insertion member 1251 for insertion into a wall panel slot to achieve connection. For example, in the wall installation of prefabricated buildings, the second insertion member 1251 of the second insertion end 125 acts like a protruding tenon, which can be inserted into a pre-reserved slot in the wall panel, like a piece of a puzzle inserted into a corresponding groove, to achieve the connection between the second adapter 120 and the wall panel.

[0057] According to the embodiments of this application, the second abutment 123 abuts against the wall and the second plug-in end 125 plugs into the wall panel slot, making the installation process of the second adapter 120 simple and convenient, and able to firmly connect with the wall and wall panel, ensuring the stability of the entire corner structure 100, and preventing it from loosening or falling off; the finishing layer of the second decorative part 124 can be selected according to different decoration styles, which can effectively improve the aesthetics of the corner and meet the decoration needs of different places; the cavity can be used to hide the wiring, making the indoor wiring neater, and can also be filled with sound insulation, heat insulation and other materials to improve the sound insulation and heat insulation performance of the corner, increasing the practicality and functionality of the corner structure 100.

[0058] For example, firstly, the first abutment 113 is pressed tightly against the wall and fixed with screws or glue to ensure it is firmly against the wall. Next, the first fitting 114 is installed on the outside of the first abutment 113; its decorative layer enhances the aesthetics of the corner. Then, the first connector 1151 of the first insertion end 115 is inserted into the slot of the wall panel. In prefabricated wall panel installation, the first connector 1151 is inserted into the pre-reserved slot in the wall panel, tightly connecting the first adapter 110 to the wall panel to form a single integrated structure. The first abutment 113, the first fitting 114, the first insertion end 115, and the first adapter end 111 are connected end-to-end to form a cavity. Sound-absorbing cotton, insulation layers, etc., can be filled into the cavity. Then, the target arc-shaped structure 130 is connected to the first adapter 110 to complete the installation of the internal corner structure 100. The installation process of the second adapter 120 is the same as that of the first adapter 110 described above, and will not be repeated here. It is understood that this application is not limited to the above installation process. For example, the first adapter 110 or the second adapter 120 can be integrally formed during manufacturing to facilitate transportation and installation and save on-site assembly time.

[0059] In some embodiments, refer to Figure 1 and Figure 2 The first slot 112 includes a T-shaped slot, and the first protrusion 132 includes a T-shaped protrusion; and / or, the second slot 122 includes a T-shaped slot, and the second protrusion 133 includes a T-shaped protrusion.

[0060] The T-shaped slot, resembling the letter "T," consists of horizontal and vertical sections. The T-shaped protrusion, also resembling the letter "T," matches the T-shaped slot, allowing it to snap into place for connection. This combination provides good connection stability and positioning accuracy. The T-shaped design prevents the protrusion from shifting within the slot during engagement, while the vertical section ensures a tight fit, preventing detachment and further enhancing the overall stability of the internal corner structure.

[0061] Figure 3 A schematic diagram of a wall panel system 300 according to an embodiment of this application is shown.

[0062] Reference Figures 1-3 The first plate segment 160 has a first groove 161 recessed towards the wall, so as to Figure 1 and Figure 2 In the indicated orientation, the first plate segment 160 has a first groove 161 recessed to the left; the second plate segment 170 has a second groove 171 recessed towards the wall, similar to the first plate segment 160. Figure 1 and Figure 2 In the indicated orientation, the second plate segment 170 has a second groove 171 recessed in the downward direction. The internal corner structure 100 also includes a first connector 1151 and a second connector 1251. The first connector 1151 and the first connector end 115 form a first slot for connection with the wall panel, and the second connector 1251 and the second connector end 125 form a second slot for connection with the wall panel.

[0063] Reference Figures 1-3 A first abutment 162 is provided on the side of the first panel segment 160 facing the wall. The first abutment 162 is specifically located at the end of the first panel segment 160. During assembly, the first panel segment 160 can abut against the leveling joist through the first abutment 162, which helps improve the stability when the first panel segment 160 and the leveling joist are connected by self-tapping screws. A second abutment 172 is provided on the side of the second panel segment 170 facing the wall. The second abutment 172 is specifically located at the end of the second panel segment 170. During assembly, the second panel segment 170 can abut against the leveling joist through the second abutment 172, which helps improve the stability when the second panel segment 170 and the leveling joist are connected by self-tapping screws.

[0064] In some embodiments, the wall panel system 300 includes the above-mentioned internal corner structure 100, a first wall panel 301 and a second wall panel 307; the first wall panel 301 is connected to the first insertion end 115 of the first transition portion 110 in the internal corner structure 100; the second wall panel 307 is connected to the second insertion end 125 of the second transition portion 120 in the internal corner structure 100.

[0065] Combination Figures 1-3 During assembly, at least a portion of the arc-shaped support of the inside corner structure 100 is fixed to the wall surface at the inside corner. The wall surface on the left side is fixed to the first leveling keel 303 by the first leveling bolt 305, and the wall surface on the lower side is fixed to the second leveling keel 304 by the second leveling bolt 306. During assembly, the target arc-shaped structure 130, the first transition part 110, the second transition part 120, the first plate end, and the second plate end are fixed to the first leveling keel 303 and the second leveling keel 304 (considered as abutting against the wall). They can be fixed to the first leveling keel 303 and the second leveling keel 304 by self-tapping screws or glue. After being fixed by self-tapping screws, the screw heads are located in the first slot 161 and the second slot 171 respectively. This prevents the screw heads from protruding from the first plate segment 160 and the second plate segment 170, thus not hindering the insertion and engagement of the first wall panel 301 with the first slot and the second wall panel 307 with the second slot.

[0066] Before assembly, the corner structure 100 is first leveled by connecting the first leveling keel 303 to the first wall surface of the corner through the first leveling bolt 305 and leveling it, and the second leveling keel 304 to the second wall surface of the corner through the second leveling bolt 306 and leveling it. Then, the target arc-shaped structure part 130, the first adapter part 110, the second adapter part 120, the first plate end and the second plate end are fixed to the first leveling keel 303 and the second leveling keel 304. After the adhesive pads 302 are set on the back of the first wall panel 301 and the second wall panel 307, they are respectively inserted into the first slot and the second slot of the corner structure 100 to form the wall panel system 300.
