Description

Technical Field

[0001] This invention relates to the field of building decoration technology, and more specifically, to a building decorative background wall structure and its installation method. Background Technology

[0002] Architectural decorative background walls are a type of background wall used in home decoration. They come in various types, are beautiful and elegant, and are widely used in home decoration and other fields. Existing architectural decorative background walls are designed with various shapes and styles, which not only meet the deeper requirements of homeowners, but also highlight the decoration style.

[0003] Most existing architectural decorative background walls are fixed to the wall for decorative purposes. During installation, edge trimming components need to be installed along the edge of the background wall panel. In related technologies, the edge trimming components of the background wall are made of stainless steel, which needs to be bent and processed on-site after verifying the dimensions. The processing difficulty and cost are relatively high, and it is impossible to make the same decorative finish as the wall panel, thus failing to meet the design effect.

[0004] Therefore, existing technologies still need improvement and development. Summary of the Invention

[0005] The purpose of this invention is to propose a building decorative background wall structure and its installation method to solve the technical problems in the prior art where the edge trimming components need to be bent and processed on-site after verifying the dimensions, which is difficult and costly to process, and cannot be made with the same decorative finish as the wall panel.

[0006] To achieve the above objectives, the first aspect of the present invention provides an architectural decorative background wall structure for installation on a building wall, the architectural decorative background wall structure comprising:

[0007] The leveling keel is fixedly installed on the building wall;

[0008] Multiple edge-finishing components are spaced apart on the leveling keel, including a supporting bottom edge connected to the leveling keel. The supporting bottom edge is provided with a limiting side plate perpendicular to the leveling keel. A low-position insert plate and a high-position insert plate are respectively protruding from both sides of the limiting side plate. The distance between the low-position insert plate and the supporting bottom edge is less than the distance between the high-position insert plate and the supporting bottom edge. The two low-position insert plates of two adjacent edge-finishing components have opposite protrusion directions. A decorative film is provided on the surface of the limiting side plate on the side where the low-position insert plate is located.

[0009] Among them, at least one of the multiple edge-sealing components is provided with a light strip groove, the limiting side plate is bent in the direction of protrusion of the high-position insert plate and forms the light strip groove that opens in the direction of protrusion of the low-position insert plate, a light strip is provided in the light strip groove, and the light strip groove is located between the low-position insert plate and the high-position insert plate;

[0010] A wall panel assembly, wherein the wall panel assembly has a mounting slot along its circumferential sidewall, and the wall panel assembly is engaged with the two lower insert plates of two adjacent edge trimming members, and / or, between the two higher insert plates of two adjacent edge trimming members, through the mounting slot.

[0011] Furthermore, the exposed surface of the wall panel assembly snapped onto the low-position insert plate is flush with the groove of the light strip recess.

[0012] Furthermore, a decorative column is provided at one end of the limiting side plate away from the bottom edge of the support, and the decorative film is provided on the surface of the decorative column. The decorative column is arranged on the same side as the high-position insert plate and covers the edge of the wall panel assembly.

[0013] In some embodiments, the wall panel assembly includes a plurality of decorative wall panels, and two adjacent decorative wall panels are assembled by I-beams to form the wall panel assembly.

[0014] Furthermore, the I-beam includes a connecting wing plate and a snap-fit ​​wing plate that are parallel to each other. The middle parts of the connecting wing plate and the snap-fit ​​wing plate are connected by a web plate, and the connecting wing plate is connected to the leveling keel.

[0015] The I-beam includes an exposed I-beam, the side wall of the decorative wall panel is snapped into the snap-fit ​​groove formed by the connecting wing plate and the snap-fit ​​wing plate, and the snap-fit ​​wing plate of the exposed I-beam is attached to the exposed surface of the decorative wall panel.

[0016] In some embodiments, the I-beam includes an embedded I-beam, and each of the decorative wall panels has a mounting slot along its circumferential sidewall, wherein the snap-fit ​​wing of the embedded I-beam snaps into the mounting slot.

[0017] Furthermore, the visible surface width of the snap-fit ​​wing plates of the decorative column and the exposed I-beam is the same.

[0018] In some embodiments, a leveling screw is provided between the leveling keel and the building wall, the leveling screw being used to adjust the flatness of the leveling keel and the distance between it and the building wall.

[0019] Furthermore, a pad is provided between the wall panel assembly and the leveling keel, which are located between the high-position insert plates. The pad is connected to the leveling keel by screws, and the wall panel assembly is bonded to the pad by structural adhesive.

[0047] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be 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.

[0048] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it may be directly or indirectly located on that other component. When a component is referred to as "connected to" another component, it may be directly or indirectly connected to that other component. The terms "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate orientations or positions based on the accompanying drawings, and are for ease of description only, and should not be construed as limiting the technical solution. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. "A plurality" means two or more, unless otherwise explicitly defined.

[0049] In a first aspect, the present invention provides an architectural decorative background wall structure, which is described below with reference to the accompanying drawings.

[0050] Please see Figure 1 , Figure 1 The diagram shows a top view of the architectural decorative background wall structure of this application when it is installed on the building wall 10. The architectural decorative background wall structure includes a leveling keel 1, an edge trimming component 2, and a wall panel assembly 3. One or more leveling keels 1 can be set and leveled and fixed on the building wall 10. Multiple edge trimming components 2 are set on the leveling keel 1 to trim the edges of the wall panel assembly 3 and assemble the wall panel assembly 3 into an integrated background wall panel. The wall panel assembly 3 is leveled and installed on the leveling keel 1.

[0051] Specifically, see Figures 1-4 Multiple edge trimming components 2 are spaced apart on the leveling keel 1, including a supporting bottom edge 21 connected to the leveling keel 1. The supporting bottom edge 21 is detachably connected to the leveling keel 1 by screws, so that the relative positions between the multiple edge trimming components 2 can be adjusted according to actual needs. The supporting bottom edge 21 is provided with a limiting side plate 22 perpendicular to the leveling keel 1. A low-position insert plate 23 and a high-position insert plate 24 protrude from both sides of the limiting side plate 22, respectively. Figure 2 , Figure 3 As shown, the low-position insert plate 23 and the high-position insert plate 24 are strip plates vertically set on the left and right sides of the limiting side plate 22. The distance between the low-position insert plate 23 and the bottom support 21 is less than the distance between the high-position insert plate 24 and the bottom support 21. The two low-position insert plates 23 of the two adjacent edge-receiving components 2 have opposite protrusion directions. The surface of the limiting side plate 22 on the side where the low-position insert plate 23 is set is provided with a decorative film 25. The decorative film 25 is a decorative layer that is sprayed or covered with the same color as the wall panel assembly 3 on the surface of the limiting side plate 22.

[0052] The wall panel assembly 3 has an installation slot 32 along its circumferential sidewall. The wall panel assembly 3 is engaged with the two low-position insert plates 23 of the two adjacent edge trimming members 2 through the installation slot 32, and / or between the two high-position insert plates 24 of the two adjacent edge trimming members 2, so that the wall panel assembly 3 can be assembled into an integrated background wall panel.

[0053] It is understandable that the two low-position inserts 23 of two adjacent edge trimming components 2 protrude in opposite directions, which means that the two high-position inserts 24 of two adjacent edge trimming components 2 also protrude in opposite directions. After the wall panel assembly 3 is assembled, it forms a background wall panel with a textured surface.

[0054] Since the wall panel components 3 are distributed in a concave-convex manner on the leveling keel 1, some edge trimming components 2 will inevitably be exposed. In some related technologies, some edge trimming components 2 are made of stainless steel bending without a decorative surface layer, which seriously affects the decorative effect of the background wall. Other edge trimming components 2 have a decorative surface layer on each surface, but the processing difficulty and cost are also increased as a result.

[0055] In this embodiment, the distance between the low-position insert plate 23 and the support bottom edge 21 is smaller than the distance between the high-position insert plate 24 and the support bottom edge 21. As a result, when the wall panel assembly 3 between two adjacent edge trimming members 2 is snapped onto the low-position insert plate 23, the side wall of the limiting side plate 22 on one side of the low-position insert plate 23 is exposed. A decorative film 25 is set on this side, and the decorative film 25 complements the finish of the wall panel assembly 3. The background wall structure with a sense of design can be observed from all angles, which greatly improves the design effect and aesthetics of the background wall structure. When the wall panel assembly 3 between two adjacent edge trimming members 2 is snapped onto the high-position insert plate 24, the side wall of the limiting side plate 22 on one side of the high-position insert plate 24 is blocked by the high-position insert plate 24. Therefore, there is no need to set a decorative film 25 on this side, which reduces the processing difficulty and cost, and saves energy and reduces emissions.

[0056] To further enhance the decorative effect, at least one of the multiple edge trimming components 2 is provided with a light strip groove 26. That is, a light strip groove 26 is provided on some edge trimming components 2, while another part is not provided with a light strip groove 26. A light strip 27 is provided in the light strip groove 26. In the actual installation process, edge trimming components 2 with light strip grooves 26 can be selected according to design requirements to make the background wall structure more design-oriented under the illumination of light.

[0057] For ease of distinction, in this embodiment, the edge-trimming component 2 with the LED strip groove 26 is collectively referred to as the LED strip edge-trimming component, such as... Figure 2As shown, the limiting side plate 22 of the light strip edge trim is bent in the direction of protrusion of the high-position insert plate 24 and forms a light strip groove 26 with an opening in the direction of protrusion of the low-position insert plate 23. The light strip groove 26 is located between the low-position insert plate 23 and the high-position insert plate 24. Through the above structural design, after the wall panel assembly 3 is installed between the edge trim members 2, the light strip groove 26 of the light strip edge trim will be automatically covered between the wall panel assembly 3 and the leveling keel 1. That is, the light strip groove 26 will be hidden and will not affect the appearance of the background wall structure. Moreover, the light of the light strip 27 can be emitted laterally from between the two wall panel assemblies 3 installed on the low-position insert plate 23 and the high-position insert plate 24 respectively, providing a backlight effect with a sense of design for the background wall structure. It can also avoid the situation where the light shines backward onto the wall panel assembly 3, causing diffuse reflection and resulting in uneven backlight and insufficient brightness.

[0058] In some implementations, such as Figure 2 As shown, the exposed surface of the wall panel assembly 3 that is snapped onto the low-position insert plate 23 is flush with the groove of the light strip groove 26 of the light strip trim piece. It can also be understood that the groove of the light strip groove 26 is smoothly connected with the exposed surface of the wall panel assembly 3 that is snapped onto the low-position insert plate 23. The purpose is to prevent the wall panel assembly 3 of the low-position insert plate 23 from blocking the light of the light strip 27, so that the light strip trim piece can achieve a better backlight effect. In addition, the background wall structure after assembly is more compact and neat, without too many structural protrusions.

[0059] In some implementations, the supporting bottom edge 21, limiting side plate 22, high-position insert plate 24, low-position insert plate 23, and light strip groove 26 are pre-processed into an integral edge trimming component 2 in the factory using a pressing process. The wall panel assembly 3 is pre-processed in the factory to form an installation groove. The specifications and dimensions of the installation groove are consistent with those of the high-position insert plate 24 and the low-position insert plate 23. The thickness specifications of the multiple wall panel assemblies 3 are consistent, which makes the wall panel assembly 3 and the edge trimming component 2 more compatible during assembly and achieves precise installation.

[0060] In some embodiments, the wall panel assembly 3 and the edge trimming component 2 are both prefabricated parts pre-processed in the factory, and their dimensions are matched. Therefore, the assembly method can be adjusted according to actual needs during the construction and assembly process so that the wall panel assembly 3 can achieve different concave and convex effects.

[0061] For example, see Figures 2-4The length of the limiting side plate 22 of the light strip edge trim is set to be longer, and the length of the limiting side plate 22 of the other edge trim components 2 without light strip groove 26 is the same. Here, the length refers to the distance between the end of the limiting side plate 22 connected to the support bottom edge 21 and the end away from the support bottom edge 21. During assembly, firstly, one LED strip edge trim is installed on the leveling keel 1. Then, an edge trim component 2 without LED strip groove 26 is set on one side of the LED strip edge trim, and another LED strip edge trim is set on the other side. Finally, the wall panel assembly 3 is installed and leveled. The wall panel assembly 3 between the LED strip edge trim and the edge trim component 2 without LED strip groove 26 is snapped onto the corresponding high-position insert plate 24. Thus, the background wall panel formed after assembly can present at least three wall panel assemblies 3 with different degrees of protrusion. That is, the wall panel assembly 3 between the LED strip edge trim and the edge trim component 2 without LED strip groove 26 has the highest degree of protrusion, the wall panel assembly 3 between the two LED strip edge trims has the lowest degree of protrusion, and the wall panel assembly 3 between the two edge trim components 2 without LED strip groove 26 has a medium degree of protrusion.

[0062] It is understood that leveling screws 11 are provided between the leveling keel 1 and the building wall 10. The leveling screws 11 are used to adjust the flatness of the leveling keel 1 and its distance from the building wall 10. This allows for the adjustment of the positions of the light strip edge trim and the edge trim components 2 without light strip grooves 26, ensuring that the wall panel assemblies 3 are installed flat between each edge trim component 2. Figure 4 In the installation method shown, since the limiting side plate 22 of the light strip edge trim is longer, the leveling keel 1 corresponding to the light strip edge trim can be set closer to the building wall 10 by adjusting the leveling screw 11, so that the wall panel assembly 3 at each position remains flat after assembly.

[0063] Furthermore, more edge-finishing components 2 (not shown in the figure) with different length limiting side plates 22 can be set. Their assembly method and the adjustment method of the leveling keel 1 are the same as the adjustment principle of the above embodiment. Thus, the background wall panel formed after assembly can present wall panel components 3 with more diverse concave and convex degrees.

[0064] Of course, the length of the limiting side plate 22 of the light strip edge trim can also be set to be the same as the length of the limiting side plate 22 of the edge trim component 2 without the light strip groove 26 (not shown in the figure). During assembly, each edge trim component 2 is set at intervals, so that at least two wall panel components 3 with different degrees of concavity and convexity can be presented.

[0065] Combining the above-mentioned setup methods, it can be found that under the given pre-processing conditions, that is, when the edge trimming component 2 and wall panel assembly 3 of this background wall structure are set with edge trimming components 2 (including light strip edge trimming components) of different lengths of limit side plates 22 according to the requirements in the factory, the wall panel assembly 3 can be set with a variety of different concave and convex degrees to assemble background wall panels of different styles. During the assembly process, there is no need to re-compare the dimensions or adjust the dimensions of the edge trimming component 2. It has strong applicability. When decorating different building walls 10, the edge trimming component 2 can be directly selected for installation, avoiding the situation where the edge trimming component 2 needs to be designed separately for each construction and installation.

[0066] Furthermore, the background wall structure has been designed with considerable consideration for the setting of the decorative film 25 and the light strip groove 26. Regardless of the assembly method, as long as the installation is carried out in accordance with the basic assembly principle, the light strip groove 26 can be covered, and only the side of the limiting side plate 22 with the decorative film 25 is exposed. This can greatly improve the installation efficiency and avoid misinstallation.

[0067] In some implementations, see [reference] Figures 2-4 A decorative column 28 is provided at the end of the limiting side plate 22 away from the bottom support 21. The surface of the decorative column 28 is provided with a decorative film 25. The decorative column 28 is set on the same side as the high-position insert plate 24 and covers the edge of the wall panel assembly 3. The limiting side plate 22 with the decorative film 25 can decorate and unify the side of the background wall structure, while the decorative column 28 with the decorative film 25 is used to decorate and unify the front of the background wall structure.

[0068] Continue reading Figure 2 , Figure 3 The decorative column 28 and the end of the limiting side plate 22 away from the supporting bottom edge 21 are smoothly joined. A first high-position slot is formed between the decorative column 28 and the high-position insert plate 24. When the wall panel assembly 3 and the high-position insert plate 24 are inserted together, a part of the wall panel assembly 3 will be inserted into the first high-position slot, thereby covering the edge of the wall panel assembly 3 with the decorative column 28. After the decorative column 28 covers the edge of the wall panel assembly 3, the ends of the wall panel assembly 3 and the limiting side plate 22 can be uniformly decorated, making the appearance cleaner and ensuring a unified style. At the same time, the decorative column 28 can assist in the snapping of the wall panel assembly 3, making its assembly more secure and improving the structural strength.

[0069] For the LED strip edge trim, to improve the accuracy and firmness of the connection between the wall panel assembly 3 and the LED strip edge trim, please refer to... Figure 2The light strip groove 26 and the high-position insertion plate 24 form a second high-position slot. When the wall panel assembly 3 is inserted into the high-position insertion plate 24, another part of the wall panel assembly 3 will be inserted into the second high-position slot. Combined with the first high-position slot and the limiting of the mounting slot 32 in the above embodiment, multiple precise limiting of the wall panel assembly 3 is achieved, making the assembly more convenient and more secure.

[0070] Furthermore, the portion of the decorative column 28 that does not contact the wall panel assembly 3 is chamfered to reduce the risk of bumps and damage. Of course, the decorative column 28 can also be set as follows: Figure 2 , Figure 3 The square column shown can also be set as other prismatic structures, depending on the actual decoration style requirements.

[0071] Optionally, the decorative column 28 is integrally formed with the limiting side plate 22 by pressing, and the interior of the decorative column 28 is hollow to reduce the structural weight.

[0072] In some implementations, see Figure 1 , Figures 4-7 The wall panel assembly 3 includes multiple decorative wall panels 31. Two adjacent decorative wall panels 31 are assembled by I-beams to form the wall panel assembly 3. The wall panel assembly 3, which is assembled by multiple decorative wall panels 31, has greater flexibility in assembly. According to actual design requirements, even when decorating different building walls 10, different numbers of decorative wall panels 31 can be directly selected to assemble wall panel assemblies 3 of different specifications and sizes, avoiding the need to prefabricate wall panel assemblies 3 separately for each construction and installation.

[0073] In some implementations, see Figure 5 , Figure 6 The I-beam includes parallel connecting wing plates 4 and snap-fit ​​wing plates 5. The middle parts of the connecting wing plates 4 and snap-fit ​​wing plates 5 are connected by a web plate 6 to form an I-beam with an "I"-shaped cross section. The connecting wing plates 4 are connected to the leveling keel 1 by screws.

[0074] See Figure 5 The I-beam includes an exposed I-beam 7. The side wall of the decorative wall panel 31 is snapped into the snap-fit ​​groove formed by the connecting wing plate 4 and the snap-fit ​​wing plate 5. The snap-fit ​​wing plate 5 of the exposed I-beam 7 is attached to the exposed surface of the decorative wall panel 31. When the decorative wall panel 31 is connected by the exposed I-beam 7, the snap-fit ​​wing plate 5 attached to the exposed surface of the decorative wall panel 31 can play a decorative role and be used as a decorative strip protruding from the decorative wall panel 31.

[0075] See Figure 6The I-beam also includes an embedded I-beam 8. Each decorative wall panel 31 has an installation slot 32 along its circumferential sidewall. The snap-fit ​​wing plate 5 of the embedded I-beam 8 snaps into the installation slot 32. When the decorative wall panels 31 are connected by the embedded I-beam 8, the adjacent decorative wall panels 31 are directly connected and form a whole in appearance.

[0076] Therefore, wall panel components 3 of different styles can be assembled according to design requirements, such as Figure 4 As shown, the wall panel assembly 3 assembled between the high-position inserts 24 is constructed by the exposed I-beams 7. The snap-fit ​​wing plates 5 of the exposed I-beams 7 are attached to the exposed surface of the decorative wall panel 31, thereby forming a raised decorative strip on the surface of the wall panel assembly 3. The snap-fit ​​wing plates 5 of the exposed I-beams 7 can also cooperate with the decorative columns 28 to form a variety of decorative styles.

[0077] Continue reading Figure 4 The wall panel assembly 3, assembled between the low-position insert plates 23, is constructed by embedding I-beams 8. The snap-fit ​​wing plates 5 of the embedded I-beams 8 are inserted into and hidden within the mounting slots 32, resulting in a smooth surface for the wall panel assembly 3. When assembling the background wall structure, the wall panel assembly 3 can be assembled using either exposed I-beams 7 or embedded I-beams 8, depending on the design requirements.

[0078] Of course, the same wall panel component 3 can also be used to assemble a portion of the decorative wall panel 31 by using the embedded I-beam 8, and to assemble another portion of the decorative wall panel 31 by using the exposed I-beam 7 (not shown in the figure), thereby achieving a variety of different decorative effects and making it more versatile.

[0079] Further, see Figure 6 One side of the decorative wall panel 31 is exposed, and the other side forms a receiving groove 33 between it and the mounting slot 32 to accommodate the web plate 6. The receiving groove 33 is connected to the mounting slot 32 and forms an L-shaped groove. When two adjacent decorative wall panels 31 are horizontally connected, the receiving groove 33 and the mounting slot 32 of the two decorative wall panels 31 together form a T-shaped groove. In this way, when the decorative wall panel 31 is assembled by the embedded I-beam 8, the web plate 6 of the embedded I-beam 8 can be accommodated in the receiving groove 33, and the snap-fit ​​wing plate 5 of the embedded I-beam 8 can be accommodated in the mounting slot 32. At this time, the exposed surfaces of the two decorative wall panels 31 can be seamlessly connected, making the exposed surface of the wall panel assembly 3 closer to a complete plane, and the appearance is simpler and flatter.

[0080] And, as Figure 5 As shown, the accommodating groove 33 will not have a negative impact on the installation of the exposed I-beam 7, making the wall panel assembly 3 more adaptable. Even if different building walls 10 are decorated, there is no need to separately customize other I-beams and decorative wall panels 31.

[0081] Furthermore, to ensure a unified decorative style, the visible widths of the snap-fit ​​wing plates 5 of the decorative column 28 and the exposed I-beam 7 are consistent, so as to form decorative strips of the same width on the wall components, resulting in a simpler and more aesthetically pleasing appearance.

[0082] Optionally, a decorative film 25 can be provided on the snap-fit ​​wing plate 5 of the exposed I-beam 7. The function of this decorative film 25 is the same as that of the decorative film 25 on the limiting side plate 22 and the decorative column 28, and will not be described again here.

[0083] In some implementations, see [reference] Figure 1 , Figure 4 The wall panel assembly 3, which is set between the high-position insert plates 24, has a cavity between it and the leveling keel 1. In order to improve the structural strength of the background panel structure, a pad 9 is provided in the cavity. One side of the pad 9 is connected to the leveling keel 1 by screws, and the other side of the pad 9 is connected to the wall panel assembly 3 by structural adhesive 91. Thus, the cavity is eliminated by the pad 9, and the compressive strength of the wall panel assembly 3 is improved.

[0084] Furthermore, the wall panel assembly 3, positioned between the low-position insert plates 23, is connected to the leveling keel 1 via structural adhesive 91 to prevent displacement and deformation of the wall panel assembly 3 relative to the leveling keel 1. (See reference...) Figure 4 Structural adhesive 91 is distributed in dots, achieving a fixing effect while saving costs.

[0085] A second aspect of this application provides an installation method for an architectural decorative background wall structure, applicable to the architectural decorative background wall structure described in the above embodiments.
