[0001] The present invention relates to the technical field of building decoration, in particular to an indoor wall decoration panel installation structure and an installation method thereof. Background Art

[0002] Interior wall panels are a key material used in interior wall decoration. Through diverse materials, styles, and functional designs, they beautify, protect, and enhance the functionality of interior spaces. Their rich variety of colors, textures, patterns, and shapes allows them to create diverse styles, from minimalist modern to European classic, catering to diverse aesthetics. They can also conceal wall imperfections for a more visually appealing effect. Protecting the wall, they effectively resist damage from impacts, scratches, moisture, and stains, extending the wall's lifespan. Sound-absorbing panels, for example, can also reduce noise transmission and optimize the indoor acoustic environment. Specialized decorative panels significantly enhance spatial functionality. Fire-resistant decorative panels improve fire safety in public spaces, while thermal insulation panels regulate indoor temperature and reduce energy consumption. Furthermore, standardized decorative panels are quick and easy to install, significantly shortening the construction cycle. Maintenance is also extremely convenient; damage requires only replacement of the corresponding panel, saving time and cost. As a key element of interior decoration, interior wall panels comprehensively enhance the aesthetics, practicality, and durability of a space, creating a comfortable, safe, and personalized indoor environment.

[0003] Upon investigation, the disclosure (announcement) number: CN110924616A discloses "an indoor wall decoration panel installation structure and its installation method". This technology discloses "including a first fixed groove and a second fixed groove, the first fixed groove and the second fixed groove are fixedly connected with a third fixed groove through a plurality of height-adjustable parts, the first fixed groove, the second fixed groove and the third fixed groove are each provided with a buffer assembly, and the decorative panel is provided with a fixing strip matching the first fixed groove, the second fixed groove and the third fixed groove, the fixing strip is respectively slidably connected to the first fixed groove, the second fixed groove and the third fixed groove, and the ends of the first fixed groove and the second fixed groove are provided with a limiting piece for preventing the fixing strip from sliding out of the first fixed groove and the second fixed groove. It has the technical effect of simple installation structure, good stability, and can achieve rapid installation and disassembly."

[0004] However, there is a common problem with the above technical solution and the common installation of decorative panels. Generally, wall decorative panels are mostly wooden boards. After the wooden decorative panels are mounted on the wall through the dry hanging structure, due to uneven force on the mounting parts and the large area of the decorative panels, the upper decorative panels will squeeze the lower decorative panels. At the same time, they are affected by thermal expansion and contraction, and the decorative panels often bend, resulting in uneven surfaces, which affects the overall appearance and dry hanging effect. In addition, replacing new decorative panels is not only time-consuming and labor-intensive, but also greatly increases the cost.

[0005] In order to solve the above problems, this application proposes an indoor wall decoration panel installation structure and an installation method thereof. Summary of the Invention

[0006] (1) Technical problems solved In view of the deficiencies of the prior art, the present invention provides an indoor wall decoration panel installation structure and an installation method thereof, which solves the problem that wooden decoration panels are prone to bending after long-term use.

[0007] (2) Technical solution To achieve the above objectives, the present invention is implemented through the following technical solutions: an indoor wall decoration panel installation structure and an installation method thereof, comprising a track installed on a wall, the inner wall of the track being clamped with a cross-shaped hanger, a dry hanging device being installed on the cross-shaped hanger, the dry hanging device comprising a No. 1 support rod, a No. 2 support rod, an upper mounting plate and a lower tensioning plate, the lower end of the No. 1 support rod being rotatably connected to the cross-shaped hanger, the upper end of the No. 1 support rod being rotatably connected to the upper mounting plate, a first rotating shaft being provided at the middle portion of the No. 1 support rod, a side surface of the first rotating shaft being rotatably connected to the No. 2 support rod, the lower end of the No. 2 support rod being rotatably connected to the lower tensioning plate, and a decorative panel being provided on the inner wall of the upper mounting plate; An adjustment device is provided inside the cross-shaped hanger, and the adjustment device includes a threaded column, a U-shaped pull plate and a nut. The interior of the cross-shaped hanger is rotatably connected to the threaded column, and one end of the threaded column away from the cross-shaped hanger is threadedly connected to the U-shaped pull plate. The side surface of the threaded column is threadedly connected to the nut, and the side surface of the threaded column is fixedly connected to a hexagonal prism. A snap-fit device is provided inside the cross-shaped hanger, and the snap-fit device includes a No. 1 limit column, a clamping block and a No. 1 spring. One end of the No. 1 limit column is fixedly connected to the cross-shaped hanger, and the end of the No. 1 limit column away from the cross-shaped hanger is slidably connected to the clamping block. The interior of the clamping block is fixedly connected to the No. 1 spring, and the end of the No. 1 spring away from the clamping block is fixedly connected to the cross hanger, and the No. 1 limit column passes through the interior of the No. 1 spring.

[0008] Preferably, the upper end of the cross-shaped hanger is fixedly connected to a limit bracket, which has a slide groove disposed therein, adapted to fit within a guide rod, the side surface of which is fixedly connected to the second support rod. By limiting the guide rod with the limit bracket, the second support rod can be pulled by the threaded post to smoothly open the first support rod, thereby achieving longitudinal tensioning of the decorative panel.

[0009] Preferably, both ends of the first rotating shaft are rotatably connected to the U-shaped pull plate. A transverse tensioning device is provided at the end of the U-shaped pull plate away from the first rotating shaft. The transverse tensioning device includes a push rod, a connecting rod, and a tensioning plate. One end of the push rod is rotatably connected to the U-shaped pull plate, and the end of the push rod away from the U-shaped pull plate is rotatably connected to the connecting rod. The front end of the connecting rod is fixedly connected to the tensioning plate. By providing the transverse tensioning device, the decorative panel is tensioned in the transverse direction, thereby achieving multi-directional tensioning in both the longitudinal and transverse directions, making the decorative panel more evenly stressed and less susceptible to deformation and bending.

[0010] Preferably, a second limiting post is slidably connected to the interior of the tensioning plate, and an end of the second limiting post away from the tensioning plate is fixedly connected to a counter plate. A second spring is fixedly connected to the interior of the counter plate, and an end of the second spring away from the counter plate is fixedly connected to the tensioning plate. The second limiting post passes through the interior of the second spring. The rear surface of the decorative plate is provided with T-shaped guide rails symmetrically distributed vertically, and the rear surface of the decorative plate is provided with slots symmetrically distributed horizontally. The upper mounting plate and the lower tensioning plate are both adapted to the T-shaped guide rails, and the counter plate is adapted to the slots. By providing the second spring, the counter plate generates a thrust to push the decorative plate outward, and the T-shaped guide rail is pulled inward by the upper mounting plate and the lower tensioning plate. Under the combined action of the thrust and tension, the decorative plate is clamped and fixed, thereby improving stability.

[0011] Preferably, a T-shaped guide rail is fixedly connected to the front surface of the cross-shaped hanger, and the end of the connecting rod away from the tensioning plate is slidably connected to the T-shaped guide rail. Through the cooperation between the connecting rod and the T-shaped guide rail, when the push rod is pulled inward, it can push the connecting rod to expand along the T-shaped guide rail, thereby driving the abutment plate to laterally tension the two slots.

[0012] Preferably, the track is internally provided with a plurality of longitudinally distributed slots, which are adapted to fit within the card blocks. The provision of the slots facilitates the card blocks to be inserted into the slots when the cross-shaped hanger is inserted upward along the lower portion of the track. The card blocks are squeezed out of the slots when moving upward, and are ejected by a spring when reaching the next slot. Thus, the cross-shaped hanger is continuously inserted into the slots during movement until it reaches below the previous adjacent cross-shaped hanger. At this point, the cross-shaped hanger is restrained by the card blocks and slots, thereby achieving splicing of the decorative panels and preventing them from falling, thereby improving safety.

[0013] Preferably, the side surfaces of the track are fixedly connected to symmetrically distributed fixing plates, and the fixing plates are provided with slots inside. The fixing plates cooperate with the slots, and bolts are inserted into the slots to facilitate the track to be mounted on the wall.

[0014] A method for installing an indoor wall decoration panel comprises the following steps: S1. Track laying: Install multiple tracks neatly on the wall according to the length of the decorative panels, and insert the bolts into the slots to fix the tracks; S2. Equipment installation: Insert multiple cross-shaped hangers from the lower end of the track in sequence. The distance between two adjacent cross-shaped hangers is determined by the width of the decorative panel. The distance between all adjacent cross-shaped hangers remains equal. At this time, all the clamping blocks are ejected into the slots and locked by the action of the No. 1 spring; S3. Install the decorative panel: Hold the decorative panel, place the back of the decorative panel close to the upper mounting plate, and hang the upper T-shaped guide rail into the upper mounting plate. Hang the lower tensioning plate into the lower T-shaped guide rail. At this time, the No. 2 spring is in a compressed state, and the back plate fits against the back of the decorative panel. The backward pulling force provided by the upper mounting plate and the lower tensioning plate and the pushing force of the back plate form an action and reaction force to clamp the decorative panel. S4. Adjust the tension: Use a wrench to insert the hexagonal prism and rotate the threaded column. The threaded column rotates inside the U-shaped pull plate and pulls the U-shaped pull plate toward the wall. At this time, the upper mounting plate and the lower tensioning plate are slightly opened under the joint action of the No. 1 support rod and the No. 2 support rod, so that the decorative panel is longitudinally stretched. At the same time, as the U-shaped pull plate approaches the wall, the two push rods are also slightly opened, thereby pushing the abutment plate to squeeze the slot horizontally, and synchronously adjusting the horizontal tension of the decorative panel. S5. Fix the position: Tighten the nut on the threaded column to make it fit with the cross-shaped bracket. The friction generated will limit the threaded column to prevent it from rotating and loosening. S6. Clean the panels: After installing and hanging the decorative panels, clean and wipe the surface of the decorative panels to keep them clean and beautiful.

[0016] 2. A mounting structure and method for indoor wall decorative panels. By designing an adjustment device, the angle between the No. 1 support rod and the No. 2 support rod can be fine-tuned twice, so that the No. 1 support rod and the No. 2 support rod are opened to the maximum extent to form a tensioning force on the inside of the decorative panel. At the same time, the horizontal tensioning device is also linked to open to the maximum extent, so that the decorative panel is straightened from multiple directions, making its surface flat and not easy to bend.

[0017] 3.

[0024] Reference Figure 1 、 Figure 3 and Figure 8 The two ends of the first rotating shaft 8 are rotatably connected to the U-shaped pull plate 10. A transverse tensioning device is provided at the end of the U-shaped pull plate 10 away from the first rotating shaft 8. The transverse tensioning device includes a push rod 18, a connecting rod 19 and a tensioning plate 20. One end of the push rod 18 is rotatably connected to the U-shaped pull plate 10, and the end of the push rod 18 away from the U-shaped pull plate 10 is rotatably connected to the connecting rod 19. The front end of the connecting rod 19 is fixedly connected to the tensioning plate 20. By setting a transverse tensioning device, the decorative panel 7 is tensioned in the transverse direction, thereby realizing multi-directional tensioning in the longitudinal and transverse directions, so that the stress on the decorative panel 7 is more uniform and not easy to deform or bend.

The upper mounting plate 5 and the lower tensioning panel 6 are both adapted to the T-shaped guide rail 24, and the push plate 22 is adapted to the card slot 25. By setting the No. 2 spring 23, the abutment plate 22 generates a thrust to push the decorative panel 7 outward, and the T-shaped guide rail 24 is subjected to the inward pulling force of the upper mounting plate 5 and the lower tensioning plate 6. Under the combined action of the thrust and the pulling force, the decorative panel 7 is clamped and fixed, thereby improving stability.

[0025] Reference Figure 1 、 Figure 2 and Figure 5 A T-shaped guide rail 24 is fixedly connected to the front surface of the cross-shaped hanger 2, and the end of the connecting rod 19 away from the tensioning plate 20 is slidably connected to the T-shaped guide rail 24. Through the cooperation between the connecting rod 19 and the T-shaped guide rail 24, the push rod 18 can be pulled inward to push the connecting rod 19 to open along the T-shaped guide rail 24, thereby driving the abutment plate 22 to horizontally tension the two slots 25. The interior of the track 1 is provided with multiple longitudinally distributed slots 25, which are adapted to the clamping block 14. By providing the card slots 25, it is convenient for the cross-shaped hanger 2 to be inserted upward along the lower part of the track 1, and the card block 14 can be inserted into the card slots 25.

The fixing plates 26 cooperate with the slots 27, and bolts are inserted into the slots 27 to facilitate the installation of the track 1 on the wall.

[0026] A method for installing an indoor wall decoration panel comprises the following steps: S1. Track laying: multiple tracks 1 are neatly installed on the wall according to the length of the decorative panels 7 , and bolts are inserted into the slots 27 to fix the tracks 1 .

[0027] S2. Equipment installation: Insert multiple cross-shaped hangers 2 from the lower end of the track 1 in sequence. The distance between two adjacent cross-shaped hangers 2 is determined by the width of the decorative panel 7. The distance between all adjacent cross-shaped hangers 2 remains equal. At this time, all the clamping blocks 14 are ejected into the clamping slots 25 and clamped under the action of the No. 1 spring 15.

[0028] S3. Installation of decorative panel: Hold the decorative panel 7, place the back of the decorative panel 7 close to the upper mounting plate 5 and hang the upper T-shaped guide rail 24 into the upper mounting plate 5, and hang the lower tensioning plate 6 into the lower T-shaped guide rail 24.

The backward pulling force provided by the upper mounting plate 5 and the lower tensioning plate 6 and the thrust of the push plate 22 form an action force and a reaction force to clamp the decorative panel 7.

[0029] S4. Adjust the tension: Use a wrench to insert the hexagonal prism 11 to rotate the threaded column 9. The threaded column 9 rotates inside the U-shaped pull plate 10 and pulls the U-shaped pull plate 10 toward the wall. At this time, the upper mounting plate 5 and the lower tensioning plate 6 are slightly opened under the joint action of the No. 1 support rod 3 and the No. 2 support rod 4, so that the decorative plate 7 is longitudinally stretched. At the same time, as the U-shaped pull plate 10 approaches the wall, the two push rods 18 are also slightly opened, thereby pushing the abutment plate 22 to squeeze the card slot 25 laterally, and synchronously adjusting the lateral tension on the decorative plate 7.

[0030] S5. Fix the position: tighten the nut 12 on the threaded column 9 to make it fit with the cross-shaped hanger 2. The friction force generated limits the threaded column 9 to prevent it from loosening due to rotation.

[0031] S6. Cleaning the board: After the installation and hanging of the decorative board 7 is completed, the surface of the decorative board 7 is cleaned and wiped to keep it clean and beautiful.

The backward pulling force provided by the upper mounting plate (5) and the lower tensioning plate (6) and the thrust of the back plate (22) form an action force and a reaction force to clamp the decorative plate (7); S4. Adjust the tension: Use a wrench to insert the hexagonal prism (11) to rotate the threaded column (9). The threaded column (9) rotates inside the U-shaped pull plate (10) and pulls the U-shaped pull plate (10) toward the wall. At this time, the upper mounting plate (5) and the lower tensioning plate (6) are slightly opened under the joint action of the No. 1 support rod (3) and the No. 2 support rod (4), so that the decorative plate (7) is longitudinally stretched. At the same time, as the U-shaped pull plate (10) approaches the wall, the two push rods (18) are also slightly opened, thereby pushing the plate (22) to squeeze the slot (25) laterally, and synchronously adjusting the lateral tension of the decorative plate (7); S5. Tighten the nut (12) on the threaded column (9) so that it fits with the cross-shaped hanger (2). The friction force generated limits the threaded column (9) to prevent it from loosening due to rotation. 9.S6, cleaning the board: After the installation of the hanging decorative board (7) is completed, the surface of the decorative board (7) is cleaned and wiped to keep it clean and beautiful.
