Description

Technical Field

[0001] The invention relates to the field of building construction and decoration, and is a building decoration board installation structure and a use method thereof. Background Art

[0002] Building decorative panels are a type of panel primarily used for interior decoration. Existing decorative panels typically require specialized brackets, bolts, and other accessories for installation, making installation time-consuming and labor-intensive. Furthermore, after installation, they are often difficult to adjust or disassemble flexibly, making subsequent replacement and repair more complex. To address this issue, prior art, such as the Chinese patent application publication number CN117846241A, published on April 9, 2024, entitled "Assembled Magnetic Wall Panel," discloses a wall panel that can be installed using a magnetic method, enabling each panel to be individually installed and removed, making installation and maintenance more convenient. However, its disadvantage is that the mounting strips still have strict dimensional requirements during installation and use, and cannot be installed too tightly or too loosely, otherwise the gaps between adjacent wall panels can be too large or too tight, making removal difficult. Furthermore, due to the flat magnetic coupling and the lack of any force-relieving structural design, the wall panel still requires significant external force to be removed after installation, otherwise it is difficult to remove. Therefore, the installation structure of the existing magnetic wall panels needs to be improved. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the present invention aims to provide a building decorative panel installation structure and method for use in the field, thereby resolving the technical issues of existing similar wall panels or decorative panels, such as the inconvenience of installation, adjustment, and removal, the high overall installation requirements, and the long construction period. This objective is achieved through the following technical solution.

[0004] A building decorative panel installation structure, which includes a decorative panel and a fixing bracket, the fixing bracket is pre-fixed to the wall panel, and the decorative panel and the fixing bracket are fixed by magnetic attraction; the key points of its structure are that a magnetic attraction component is provided on the inner side of the decorative panel, the magnetic attraction component includes a magnetic attraction part A, a magnetic attraction part B and an auxiliary disengagement part, an installation cavity for installing the magnetic attraction component is provided on the inner side of the decorative panel, the magnetic attraction part A is fixed at the end of the installation cavity, the outer end face of the magnetic attraction part A is parallel to the inner side face of the decorative panel, a through hole is provided in the middle of the magnetic attraction part A, and the through hole forms a guide hole close to the outer end face of the magnetic attraction part A, the auxiliary disengagement part is provided with a columnar section that slides with the through hole, one end of the columnar section extends out of the inner end face of the magnetic attraction part A and is fixedly connected The magnetic component B is connected to the mounting cavity, and the other end of the cylindrical section is connected to a deformable portion distributed in a circular array relative to the axis of the cylindrical section. The fixed bracket is fixed with a magnetic component C that magnetically engages with the outer end surface of the magnetic component A. When the magnetic components A and C are engaged, a portion of the deformable portion of the auxiliary release component is located between the two components, and the other portion is located within the guide hole. When the magnetic component B pushes or pulls the auxiliary release component, the deformable portion of the auxiliary release component is guided by the guide hole of the magnetic component A and deforms, expanding the gap between the two components, thereby weakening or eliminating the magnetic attraction between the two components. This structure utilizes magnetic engagement to achieve connection between the decorative panel and the fixed bracket, making installation quick and convenient. An auxiliary disengagement part is also provided, which controls the push and pull of the magnetic part B through external magnetic force, pulls the auxiliary disengagement part to deform, expands the gap between the magnetic part A and the magnetic part C, thereby weakening or eliminating the magnetic attraction between the magnetic part A and the magnetic part C, and facilitates the quick removal of the decorative panel.

[0005] The guide hole of the magnetic part A is a tapered hole, and the deformed part of the auxiliary disengaging part is provided with a tapered part that cooperates with the tapered surface of the tapered hole of the magnetic part A, and a flat part that abuts against the plane of the outer end surface of the magnetic part A, and the taper of the inner conical surface of the tapered part is greater than the taper of the outer conical surface; in the initial state, the magnetic part B is attracted to the magnetic part A; when the magnetic part A is opposite to the magnetic part C, the deformed part of the auxiliary disengaging part is located between the magnetic part A and the magnetic part C to prevent the two from being attracted; when the decorative panel is pressed toward the fixed bracket, the auxiliary disengaging part pushes the magnetic part B to separate from the magnetic part A under the push of the magnetic part C, and the magnetic part A is attracted to the magnetic part C. After the attraction, the flat part of the auxiliary disengaging part is clamped between the magnetic part A and the magnetic part C, and the outer conical surface of the tapered part of the auxiliary disengaging part cooperates with the tapered hole of the magnetic part A. The above is a specific implementation scheme of the auxiliary disengagement member. It realizes the disengagement between the magnetic attraction member A and the magnetic attraction member C by pushing the magnetic attraction member B.

[0006] The guide hole of the magnetic part A is a tapered hole, and the deformed part of the auxiliary disengaging part is provided with a tapered part that matches the tapered hole of the magnetic part A, a flat part that abuts against the flat surface of the outer end surface of the magnetic part A, and a wedge-shaped part connected to the outer end of the flat part; in the initial state, the magnetic part B and the magnetic part A are repelled and separated, and the wedge-shaped part of the auxiliary disengaging part is located at the outer end surface of the magnetic part A; when the magnetic part A and the magnetic part C are opposite to each other, the wedge-shaped part of the auxiliary disengaging part is located between the magnetic part A and the magnetic part C to prevent the two from being attracted; when the magnetic part B is pushed toward the magnetic part A, the auxiliary disengaging part drives the wedge-shaped part to extend to the outer end surface of the magnetic part A under the push of the magnetic part B, and the magnetic part A and the magnetic part C are attracted, and the attraction force is greater than the repulsive force between the magnetic part A and the magnetic part B; when the magnetic device on the outer side of the decorative panel pulls the magnetic part B When the magnetic member B pulls the wedge-shaped portion of the auxiliary disengagement member into between the magnetic member A and the magnetic member C, thereby widening the gap between the magnetic member A and the magnetic member B. The above is a second embodiment of the auxiliary disengagement member, which disengages the magnetic member A and the magnetic member C by pulling the magnetic member B.

[0007] The outer end surface area of ​​the magnetic member A is smaller than the end surface area of ​​the magnetic member C. With this structure, the engaging surface of the magnetic member A is smaller than the engaging surface of the magnetic member C, thereby facilitating radial adjustment of the magnetic member A relative to the magnetic member C and making it easier to fine-tune the fixed position of the decorative panel.

[0008] The wedge-shaped portion of the auxiliary disengagement member is a double-sided inclined surface, or the wedge-shaped portion has an inclined surface on one side facing the outer end surface of the magnetic member A and a flat surface on the other side parallel to the end surface of the magnetic member C. This structure helps the wedge-shaped portion to reliably enter between the magnetic members A and C.

[0009] The decorative panel's end surface is fitted with a decorative surface layer. When the decorative surface layer is removed, the magnetic component B within the mounting cavity is exposed. This structure allows for the removal of the decorative surface layer if magnetic attraction fails to effectively control the magnetic component B. The manual operation of the magnetic component B then activates the auxiliary release element, releasing the force between the magnetic components A and C.

[0010] The magnetic member B is connected to a side of the decorative surface layer and is provided with a pull ring. This structure makes it easy to pull the magnetic member B.

[0011] The through hole of the magnetic member A is a circular hole or a polygonal hole, and the cylindrical section of the auxiliary disengagement member is a cylindrical or polygonal column. Through this structure, the auxiliary disengagement member can be guided and slidably relative to the through hole of the magnetic member A.

[0012] The auxiliary disengagement part based on the structure of the above-mentioned scheme 1, the use method of the building decorative panel installation structure includes an installation method and a disassembly method. The installation method is: keep the magnetic part B and the magnetic part A attracted, and the deformation part of the auxiliary disengagement part is in a convex state relative to the outer end surface of the magnetic part A. At this time, the magnetic part A of the decorative panel and the magnetic part C of the fixed bracket are aligned. After the alignment, the magnetic part A and the magnetic part C are not attracted due to the obstruction of the deformation part of the auxiliary disengagement part; when the decorative panel is pressed, the magnetic part C pushes the deformation part of the auxiliary disengagement part and drives the magnetic part B to disengage from the magnetic part A until the magnetic part A and the magnetic part C are aligned. Part C completes the attraction, and when attracted, it clamps the flat part of the auxiliary disengagement part, thus completing the fixation of the decorative panel and the fixed bracket; the disassembly method is: through an external magnetic device, a thrust is applied to the magnetic part B, and the magnetic part B drives the auxiliary disengagement part to move toward the magnetic part A, and the deformed part of the auxiliary disengagement part moves along the gap between the magnetic parts A and B under the guidance of the tapered hole of the magnetic part A, so that the gap between the magnetic parts A and C becomes larger, and the magnetic attraction between the magnetic parts A and C is weakened or eliminated. At this time, the decorative panel can be pulled outward to separate it from the fixed bracket, thereby realizing the disassembly of the decorative panel.

[0013] Based on the auxiliary disengaging part of the structure of the above-mentioned scheme 2, the method of using the building decorative panel installation structure includes an installation method and a disassembly method. The installation method is: the magnetic part B is away from the magnetic part A under the repulsive force of the magnetic part A, and the wedge-shaped part of the auxiliary disengaging part is located at the outer end surface of the magnetic part A; at this time, the magnetic part A of the decorative panel is aligned with the magnetic part C of the fixed bracket. After the alignment, the magnetic part A and the magnetic part C are not attracted due to the obstruction of the wedge-shaped part of the auxiliary disengaging part; when the magnetic part B is pushed toward the magnetic part A by an external magnetic device, the magnetic part B pushes the wedge-shaped part of the auxiliary disengaging part to extend to the outer end surface of the magnetic part A , until the magnetic parts A and C are completely attracted, and the flat part of the auxiliary disengagement part is clamped during the attraction. At this time, the attraction between the magnetic parts A and C is greater than the repulsion between the magnetic part A and the magnetic part B, that is, the fixation of the decorative panel and the fixed bracket is completed; the disassembly method is: through an external magnetic device, a pulling force is applied to the magnetic part B, and the magnetic part B pulls the wedge-shaped part of the auxiliary disengagement part into between the magnetic parts A and B, so that the gap between the magnetic parts A and C becomes larger, and the magnetic attraction between the magnetic parts A and C is weakened or eliminated. At this time, the decorative panel can be pulled outward to separate from the fixed bracket, thereby realizing the disassembly of the decorative panel.

[0014] The present invention utilizes magnetic attraction to not only enable quick installation of the decorative panel and facilitate adjustment after installation, but also features an auxiliary release mechanism that quickly removes the magnetic attraction between the decorative panel and the mounting bracket, allowing for quick removal and replacement of the decorative panel. The overall design is convenient, saving time and effort. It is suitable for use as a mounting structure for various decorative panels, or as an improvement to similar mounting structures.

[0027] The present invention will now be further described with reference to the accompanying drawings.

[0028] like Figure 1-Figure 4 The first embodiment is shown. The building decorative panel installation structure includes a decorative panel 1 and a fixed bracket 2. A magnetic assembly is provided on the inner side of the decorative panel. The magnetic assembly includes a magnetic component A3, a magnetic component B5, and an auxiliary release component 4. The decorative panel is provided with a magnetic component C6 that is aligned with the magnetic component A, and the magnetic component C is convex relative to the end face of the fixed bracket. A mounting cavity 101 for mounting the magnetic assembly is provided on the inner side of the decorative panel. The magnetic component A is fixed at the end of the mounting cavity. The outer end face of the magnetic component A is parallel to the inner side face of the decorative panel, and is preferably configured so that the outer end face of the magnetic component A convex relative to the inner side face of the decorative panel. A through hole is provided in the middle of the magnetic component A. The through hole is a circular hole or a polygonal hole. A guide hole is formed near the outer end face of the magnetic component A. The guide hole is a conical hole. The auxiliary release component is provided with a columnar section 401 that slides with the through hole. The columnar section is a cylindrical or polygonal column. One end of the cylindrical segment extends out of the inner end face of the magnetic component A and is fixedly connected to the magnetic component B in the mounting cavity. The other end of the cylindrical segment is connected to a deformation portion distributed in a ring array relative to the axis of the cylindrical segment. The deformation portion is provided with a conical portion 402 that cooperates with the conical surface of the conical hole of the magnetic component A, and a flat portion 403 that abuts against the plane of the outer end face of the magnetic component A. The taper of the inner conical surface of the conical portion is greater than the taper of the outer conical surface.

[0029] The installation and use method of this embodiment 1 is as follows: in the initial state, magnetic component B5 and magnetic component A3 remain engaged, and the deformed portion of the auxiliary release component 4 is raised relative to the outer end surface of magnetic component A. When installing the decorative panel 1, first align magnetic component A with magnetic component C6. During alignment, the deformed portion of the auxiliary release component is located between magnetic components A and C, preventing them from engaging, thereby facilitating adjustment of the decorative panel's position. After alignment is complete, the decorative panel is pressed toward the fixed bracket 2. The auxiliary release component, pushed by magnetic component C, pushes magnetic component B5 and magnetic component A3 apart until magnetic components A and C engage. After engagement, the flat portion 403 of the auxiliary release component is clamped between magnetic components A and C, and the outer conical surface of the tapered portion 402 of the auxiliary release component mates with the tapered hole of magnetic component A, completing the magnetic fixation of the decorative panel to the fixed bracket. When it is necessary to disengage the magnetic parts A and C, the thrust that repels the magnetic parts B is turned on through the external magnetic device, pushing the above-mentioned magnetic parts B to drive the auxiliary disengagement parts to move axially. The conical part of the auxiliary disengagement part is deformed under the guidance of the conical hole and the flat part of the magnetic parts A, and enters between the magnetic parts A and C, expanding the gap between the magnetic parts A and C, thereby weakening or eliminating the magnetic attraction between the magnetic parts A and C. The decorative panel can be separated from the fixed bracket by pulling it outward, thereby achieving quick disassembly.

[0030] like Figure 5-Figure 8The second embodiment is shown. This embodiment differs from the first embodiment in that the deformable portion of the auxiliary release member includes a tapered portion 402 that mates with the tapered hole of magnetic member A3, a flat portion 403 that abuts the outer end surface of magnetic member A, and a wedge-shaped portion 404 connected to the outer end of the flat portion. In the initial state, magnetic member B and magnetic member A are repelled and separated, and the wedge-shaped portion of the auxiliary release member is located on the outer end surface of magnetic member A.

[0031] The installation and use method of this second embodiment is as follows: the magnetic component B5 moves away from the magnetic component A under the repulsive force of the magnetic component A3, and the wedge-shaped portion 404 of the auxiliary disengagement component 4 is located at the outer end surface of the magnetic component A. When installing the decorative panel 1, the magnetic component A and the magnetic component C6 are first aligned. During the alignment, the wedge-shaped portion of the auxiliary disengagement component is located between the magnetic component A and the magnetic component C to prevent the two from being attracted. When the magnetic component B is pushed toward the magnetic component A by an external magnetic device, the magnetic component B pushes the wedge-shaped portion of the auxiliary disengagement component to extend to the outer end surface of the magnetic component A until the magnetic component A and the magnetic component C are completely attracted. The attraction force is greater than the repulsive force between the magnetic component A and the magnetic component B. When attracted, the magnetic component A and the magnetic component C clamp the flat portion 403 of the auxiliary disengagement component, thus completing the magnetic fixation of the decorative panel to the fixing bracket 2. When the decorative panel needs to be removed, an attractive pulling force is applied to the magnetic part B through an external magnetic device. The magnetic part B pulls the wedge-shaped part of the auxiliary disengagement part into between the magnetic parts A and B, so that the gap between the magnetic parts A and C becomes larger, and the magnetic attraction between the magnetic parts A and C is weakened or eliminated. At this time, the decorative panel can be pulled outward to separate it from the fixed bracket, thereby realizing rapid disassembly of the decorative panel.

[0032] In the above-mentioned embodiment 1 and embodiment 2, the outer end surface area of ​​the magnetic component A3 is smaller than the end surface area of ​​the magnetic component C6, which facilitates the radial adjustment of the magnetic component A relative to the magnetic component C, that is, the adjustment of the decorative plate relative to the fixed bracket.

[0033] In the above second embodiment, the wedge-shaped portion 404 of the auxiliary disengagement member 4 is a double-sided inclined surface, or one side facing the outer end surface of the magnetic attraction member A is an inclined surface, and the other side is a plane parallel to the end surface of the magnetic attraction member C6.

[0034] like Figure 9 As shown, the end surface of the decorative plate 1 of the embodiment 1 and the embodiment 2 can also be provided with a fitting decorative surface layer 102. When the decorative surface layer is removed, the magnetic element B5 in the installation cavity 101 is exposed, thereby facilitating manual direct operation of the magnetic element B. Figure 10 As shown, in accordance with the second embodiment, a pull ring 501 is provided on one side of the magnetic element B relative to the decorative surface layer to facilitate the pulling operation.

[0035] like Figure 11As shown, when the decorative panel is actually installed and used, a magnetic component is set in the middle and / or four corners of the decorative panel 1, and a fixing bracket is pre-installed on the wall by bolts. After fixing, the installation panels can be magnetically fixed on the wall one by one in sequence. While magnetically attracting, the panels can also be fine-tuned horizontally to align adjacent decorative panels closely to form a better external decorative surface.

[0036] The above content is intended to illustrate the technical means of the present invention and is not intended to limit the technical scope of the present invention. Those skilled in the art may make obvious improvements or substitutions to the present invention in combination with existing common knowledge, which also fall within the scope of protection of the claims of the present invention.
