Description

Technical Field

[0001] The present invention relates to the technical field of wall decoration, and more particularly to a background wall structure for concealing protruding lights outside decorative lines and an installation method thereof. Background Art

[0002] In current building decoration projects, some places need to build background walls to make the wall surface more beautiful. The existing commonly used prefabricated wall panel structure usually only lays a layer of decorative panels on the wall surface, and the three-dimensional layering of the background wall of such a structure is poor.

[0003] In order to increase the three-dimensional layering of the background wall, multi-layer prefabricated wall panels can be used as the background wall. However, when the prefabricated wall panels are used as the background wall for construction, there is a lack of decorative connecting components between the upper and lower layers. Traditional connecting components are processed by bending stainless steel plates. During use, they need to be resized on site and matched on site according to the actual installation size of the wall panels after construction, which greatly increases the processing difficulty, resulting in low construction efficiency, and is therefore labor-intensive, time-consuming and costly.

[0004] Therefore, the existing technology still needs to be improved and developed. Summary of the Invention

[0056] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

When a component is referred to as being "connected to" another component, it may be directly or indirectly connected to the other component. The directions or positions indicated by the terms "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the directions or positions shown in the accompanying drawings and are only for the convenience of description and cannot be understood as limitations on this technical solution. The terms "first" and "second" are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. "Multiple" means two or more, unless otherwise clearly and specifically defined.

[0058] If the existing construction method of prefabricated wall panels is used to build the background wall structure, the traditional stainless steel bent components not only need to be matched and processed on site, resulting in processing difficulties and low construction efficiency, but also require the use of many screws to form the connection points during the fixing process, and the connection points are difficult to hide, further increasing the construction difficulty. In addition, the stainless steel components cannot be decorated with the same finish as the wall panels, resulting in an inconsistent overall effect of the background wall, which greatly reduces the decorative effect of the background wall. To address the above problems, this application optimizes them through the following embodiments, as follows:

[0059] Example 1

[0060] See also Figure 1This embodiment provides a background wall structure for concealing a decorative line protruding light, which is used to cover the surface of a wall 100. For the convenience of structural description, the structure is described by taking the state where the background wall structure is set on the surface of the wall 100 as an example. The side where the wall 100 is located is regarded as the back, and the side where the background wall structure is located is regarded as the front. The wall 100 generally has a front surface and a side surface. The front surface is the surface that the user's eyes face, and the side surface can be a wall surface located to the left and right of the front surface and perpendicular to the front surface. The front surface and the side surface of the wall 100 enclose an indoor space. The background wall structure for concealing a decorative line protruding light mainly includes: an inner concave background portion 200, an outer convex background portion 300, a side wall background portion 600, and a background wall connection assembly. The inner concave background portion 200 is connected to the front surface of the wall 100. The inner concave background portion 200 covers a portion of the front surface of the wall 100. Therefore, the front surface of the inner concave background portion 200 forms a partial decorative surface, which has a decorative effect. The convex background portion 300 is connected to the front surface of the wall 100 and is located on the side (front) of the concave background portion 200 facing away from the wall 100. One side edge of the convex background portion 300 overlaps with the first edge of the concave background portion 200 in the front-to-back direction. For example, the first edge of the concave background portion 200 is the right edge, and the left edge of the convex background portion 300 is located to the left of the right edge of the concave background portion 200, while the right edge of the concave background portion 200 is located to the right of the left edge of the convex background portion. A gap is provided between the convex background portion 300 and the concave background portion 200 in the front-to-back direction, which is used to install the background wall connection assembly. The side wall background portion 600 is connected to the side surface of the wall 100 and is connected to the second edge of the concave background portion 200 via a female corner connection member 700. The first and second edges are opposite edges, so the second edge can be the left edge of the concave background portion 200. By connecting the side wall background portion 600 and the recessed background portion 200 via the internal corner connecting member 700, the left edge of the recessed background portion 200 and the rear edge of the side wall background portion 600 can block each other, thereby rounding off the corners of the background wall structure and making the corners more flat. Furthermore, the internal corner connecting member 700 can secure the left edge of the recessed background portion 200 to the rear edge of the side wall background portion 600, making the background wall structure more stably connected to both sides of the wall 100.

[0061] The background wall connection assembly includes a detachably connected side trimming member 500 and a fixed clipping member 400. The side trimming member 500 is connected to the convex background portion 300, and the fixed clipping member 400 is connected to the concave background portion 200. Through the detachable connection of the side trimming member 500 and the fixed clipping member 400, a faster assembly method can be achieved while ensuring a firm installation, which helps to improve assembly efficiency.

[0062] See also Figure 1 、 Figure 2 、 Figure 5 The side trimming component 500 specifically includes a trimming portion 510, a receiving portion 520, and a plug-in portion 530. The trimming portion 510 is connected to one side edge of the convex background portion 300 and is used to cover the edge of the convex background portion 300 to achieve a trimming function. The receiving portion 520 is connected to the trimming portion 510 and is concave toward the first edge. The receiving portion 520 is located between the convex background portion 300 and the concave background portion 200. A light-emitting component 524 is provided in the receiving portion 520. The light-emitting component 524 does not protrude from the edge of the trimming portion 510 and is hidden by the receiving portion 520. The plug-in portion 530 is connected to the receiving portion 520 and is used to be pluggable and connected to the fixed clamping component 400. In the specific structure, the trimming portion 510, the receiving portion 520, and the plug-in portion 530 are integrally formed. The trimming portion 510 can be detachably positioned on the left edge of the convex background portion 300. When the side trimming member 500 is connected to the convex background portion 300, the trimming portion 510 is sleeved onto the left edge of the convex background portion 300 to achieve trimming. The receiving portion 520 is located at the rear side of the trimming portion 510 and is recessed to the right to form a slot. The light-emitting element 524 is fixed in the slot and emits light toward the slot. The plug-in portion 530 is located at the rear side of the receiving portion 520 and extends a certain distance to the right to facilitate plug-in connection.

[0063] The fixed clamping member 400 specifically includes a connecting portion 410 and a clamping portion 420. The connecting portion 410 is fixedly connected to the first edge of the recessed background portion 200, and the clamping portion 420 is fixedly connected to the connecting portion 410. The plug-in portion 530 abuts against the front surface of the recessed background portion 200 and plugs into the clamping portion 420. In the specific structure, the connecting portion 410 and the clamping portion 420 are integrally formed. The connecting portion 410 is fixedly connected to the right edge of the recessed background portion 200, and the clamping portion 420 is positioned toward the left, thereby allowing for plug-in and removable connection with the plug-in portion 530.

[0064] See also Figure 1 、 Figure 2 、 Figure 5In this embodiment, a background wall structure with hidden decorative line and protruding lights is provided, by setting a convex background part 300 on the front side of the concave background part 200, thereby forming a multi-layer background structure, making the background wall more three-dimensional and layered. In the process of connecting the concave background part 200 with the convex background part 300, a detachable side trimming component 500 and a fixed clamping component 400 are used to cooperate with the fixed clamping component 400 and the internal corner connecting component 700. The concave background part 200 is first fixedly connected, and then the plug-in part 530 of the side trimming component 500 is inserted into the clamping part 420 of the fixed clamping component 400, and the trimming part 510 of the side trimming component 500 trims the convex background part 300. Therefore, through the cooperation of the fixed clamping component 400 and the side trimming component 500, not only the fixed connection of the concave background part 200 is achieved, but also the convex background part 300 can be stably connected to the concave background part 200, and the convex background part 300 is trimmed. Multiple functions are achieved through one combined component, which greatly improves assembly efficiency and saves production costs. Because of the plug-in assembly connection method, during the construction process, if the concave background portion 200 and the convex background portion 300 produce a slight deviation in workability, the plug-in portion 530 can be used to match the appropriate insertion amount based on the actual size, thus achieving a stable connection between the concave background portion 200 and the convex background portion 300. Therefore, it can be mass-produced according to standard parts and does not require on-site dimensional adjustment during use during construction, which reduces processing difficulty, further improves construction efficiency, and thus reduces project costs. In addition, the edge trimming portion 510 not only achieves the side edge trimming of the convex background portion 300, making the structure more beautiful, but also its surface can be sprayed, coated with the same color, and other decorative effects, enriching the decorative effect. A receiving portion 520 is formed on the side trim component 500, and a light-emitting component 524 is hidden in the receiving portion 520 to emit light; not only a lighting effect is formed between the multi-level background walls, further improving the decorative effect of the background wall structure and ensuring the decorative effect of the light strip, but also, combined with the structural characteristics of the side trim component 500, the light-emitting component 524 is hidden, so that the structure of the background wall is further optimized, and the joints between the multi-level background walls are reasonably hidden. When looking at the background wall structure from the front, no decorative seams can be seen, which makes the decorative effect of the background wall structure better.

[0065] See also Figure 1 、 Figure 2 、 Figure 5Furthermore, the concave background portion 200 in this embodiment specifically includes: a first leveling keel 210 and a first decorative wall panel 220. The first leveling keel 210 is connected to the front surface of the wall 100 via the leveling adjustment screws 110, and the first decorative wall panel 220 covers the first leveling keel 210. During the installation process, the first leveling keel 210 is leveled using the leveling adjustment screws 110 so that the first leveling keel 210 is fixed to the wall 100 according to the design requirements and is flat as a whole, providing a foundation for the installation of the first decorative wall panel 220. The first decorative wall panel 220 is located on the front side of the first leveling keel 210, and the edge of the first leveling keel 210 protrudes from the first edge of the first decorative wall panel 220. Specifically, in the left-right direction, the right edge of the first leveling keel 210 protrudes from the right edge of the first decorative wall panel 220. Since the first leveling keel 210 protrudes toward the right, it can provide an installation position for the fixed clamping component 400. When the first decorative wallboard 220 is connected to the first leveling keel 210 , structural adhesive 130 is applied to the back side of the first decorative wallboard 220 to increase the connection stability between the first decorative wallboard 220 and the first leveling keel 210 .

[0066] See also Figure 1 、 Figure 2 、 Figure 5 In the fixed clamping member 400 of this embodiment, the connecting portion 410 specifically includes a first support plate 411. The first support plate 411 extends a certain length in the left-right direction and is fixedly connected to the first leveling keel 210 by means of screws 120. The clamping portion 420 includes a vertical clamping arm 421 and a clamping edge 422. The vertical clamping arm 421 is vertically connected to the middle position of the first support plate 411 in the left-right direction, thereby dividing the first support plate 411 into a left section and a right section. The clamping edge 422 is connected to the vertical clamping arm 421 and forms a clamping groove 423 between the clamping edge 422 and the first support plate 411. That is, the clamping groove 423 is formed in the left section, while the right section is empty, thereby facilitating the installation of the screws 120. When the first decorative wall panel 220 is inserted into the retaining groove 423 for positional fixation, the plug-in portion 530 of the side trim member 500 abuts against the first decorative wall panel 220 and, together with the first edge of the first decorative wall panel 220, is engaged in the retaining groove 423. The use of the fixed retaining member 400 not only stably secures the first decorative wall panel 220 to the first leveling keel 210 at one side edge of the first decorative wall panel 220, but also supports the plug-in portion 530 of the side trim member 500 through the first decorative wall panel 220 during insertion, thereby stably connecting the convex background portion 300 to the concave background portion 200 via the side trim member 500.

[0067] See also Figure 1 、 Figure 2 、 Figure 5The rear surface of the first support plate 411 protrudes rearward to form a boss structure 414. During the molding process of the first support plate 411, a corresponding depression is formed on the front surface of the boss structure 414 to form an inner groove 412. The rear surface of the boss structure 414 abuts against the front surface of the first leveling keel 210. The screw 120 is inserted into the inner groove 412 and fixedly connected to the front surface of the first leveling keel 210. The boss structure 414 of the first support plate 411 abuts against the back surface of the first leveling keel 210, thereby supporting and limiting the connection between the fixed clamping member 400 and the first leveling keel 210. Moreover, the rear surface of the first support plate 411 is only abutted and limited by the boss structure 414, preventing the entire rear surface of the first support plate 411 from abutting against the back surface of the first leveling keel 210, thereby reducing the contact area with the uneven surface area of ​​the front surface of the first leveling keel 210, and facilitating the stable connection of the fixed clamping member 400 to the front surface of the first leveling keel 210. The inner groove 412 provides a countersink position for the screw 120, preventing the head of the screw 120 from protruding forward and interfering with the installation of other structures. In this embodiment, end bosses 413 are further provided at the left and right ends of the first support plate 411. The end bosses 413 are disposed at the edges of the rear surface of the first support plate 411. The surface of the end bosses 413 facing the first leveling keel 210 is flush with the surface of the boss structure 414 facing the first leveling keel 210, and the end bosses 413 abut against the front surface of the first leveling keel 210. The end bosses 413 cooperate with the boss structure 414 so that the first support plate 411 can abut and align with the front surface of the first leveling keel 210 at least at two locations in the left and right directions, thereby more stably connecting the first support plate 411 to the first leveling keel 210 and preventing the fixed first support plate 411 from loosening.

[0068] See also Figure 2 、 Figure 5 In this embodiment, a nail groove 415 is defined within the inner recess 412, and the screw 120 is positioned within the nail groove 415. The screw 120 is a self-tapping screw. The self-tapping screw penetrates the first support plate 411 at the location of the nail groove 415 along the front-to-back direction and connects to the first leveling keel 210, thereby securing the first support plate 411 to the first leveling keel 210. The nail groove defines the position of the self-tapping screw, preventing it from shifting during the nailing process, making installation faster and simpler. This structure further stabilizes the connection between the fixed clamping member 400 and the first leveling keel 210.

[0069] See also Figure 1 、 Figure 2 、 Figure 5Furthermore, the clamping edge 422 in this embodiment specifically includes: a clamping horizontal plate 424 and a protruding limiting plate 425. One end of the clamping horizontal plate 424 is connected to the clamping vertical arm 421 and is parallel to the first support plate 411. The clamping horizontal plate 424 and the first support plate 411 are used to clamp the first edge of the first decorative wall panel 220. The right edge of the first decorative wall panel 220 is embedded between the clamping horizontal plate 424 and the first support plate 411, thereby fixing one side of the first decorative wall panel 220 by fixing the clamping member 400. The protruding limiting plate 425 is connected to the other end of the clamping horizontal plate 424 and is located on the front side of the clamping horizontal plate 424. A docking groove is formed between the protruding limiting plate 425 and the front surface of the first decorative wall panel 220, and the plug-in portion 530 is embedded in the docking groove.

When the first decorative wall panel 220 is inserted and abuts against the clamping horizontal plate 424, a gap is formed between the front surface of the first decorative wall panel 220 and the protruding stopper plate 425. This gap facilitates the insertion of the plug-in portion 530. During the assembly process, by inserting the plug-in portion 530 into the docking groove, the plug-in is facilitated while not causing compression on the front surface of the first decorative wall panel 220, thereby preventing damage to the decorative panel.

[0070] See also Figure 1 、 Figure 2 、 Figure 5 Furthermore, the raised background portion 300 in this embodiment specifically includes: a second leveling keel 310 and a second decorative wall panel 320. The second leveling keel 310 is connected to the front surface of the wall 100, and the second decorative wall panel 320 is located in front of the second leveling keel 310. The edge of the second decorative wall panel 320 protrudes from the edge of the second leveling keel 310. During installation, the second leveling keel 310 is leveled using the leveling adjustment screws 110, so that the second leveling keel 310 is fixed to the wall 100 according to design requirements. It can also be located in front of the first decorative wall panel 220 to make the front surface of the second leveling keel 310 overall flat, providing a foundation for the installation of the second decorative wall panel 320. The second decorative wall panel 320 is located in front of the second leveling keel 310. The edge of the second decorative wall panel 320 protrudes beyond the edge of the second leveling keel 310. Specifically, in the left-right direction, both edges of the second decorative wall panel 320 protrude beyond the edges of the second leveling keel 310. Because the light-emitting element 524 needs to be concealed, the left and right edges of the second leveling keel 310 are recessed to form steps. This provides clearance for the side trim 500, facilitating its installation.

[0071] See also Figure 1 、 Figure 2 、 Figure 5 In this embodiment, the trimming portion 510 is used to wrap around the edge of the second decorative wallboard 320, and the receiving portion 520 is located at the step formed by the second decorative wallboard 320 and the second leveling keel 310. After the trimming portion 510 trims the edge of the second decorative wallboard 320, the receiving portion 520 not only conceals the light-emitting element 524 but also supports the second decorative wallboard 320. Together with the second leveling keel 310, the receiving portion 520 forms a support structure for the second decorative wallboard 320, further stabilizing the connection of the second decorative wallboard 320. The plug-in portion 530 includes a plug-in plate 531, which rests on the front surface of the first decorative wall panel 220 and is plugged into the docking groove; the plug-in plate 531 extends a certain length in the right direction, and the plug-in plate 531 not only realizes the connection between the side trim component 500 and the fixed clamping component 400 by being plugged into the docking groove, but also the plug-in plate 531 rests on the front surface of the first decorative wall panel 220 to form a stable supporting structure, thereby improving the structural strength of the entire side trim component 500, making the structure more stable and having a stronger load-bearing capacity.
