Description

Technical Field

[0001] This invention relates to the field of quick-installation ceiling and wall panel technology, and more particularly to a lightweight quick-installation ceiling and wall panel. Background Technology

[0002] Wall panels are a type of building structure consisting of walls and floor slabs forming a load-bearing system. Simply put, they are a new type of wall material that has developed with the rise of prefabricated large-panel buildings. There are many types and styles of wall panels available on the market, including PVC wall panels, stone-plastic panels, bamboo and wood fiber wall panels, and wooden wall panels. People can choose according to their personal preferences to decorate and beautify their homes.

[0003] The current installation process for gypsum board ceiling panels involves first installing the main and secondary keels in a lattice pattern to the living room ceiling, and then using self-tapping screws to install the gypsum board ceiling panels from the bottom to the secondary keels. This installation process not only causes pits and damage to the bottom of the gypsum board ceiling panels, affecting their aesthetic appearance, but also requires multiple installations of self-tapping screws, making the installation of gypsum board ceiling panels cumbersome and preventing them from being installed quickly. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art that not only cause pit damage to the lower end of the gypsum board ceiling and wall panel, affecting the aesthetic appearance of the lower end of the gypsum board ceiling and wall panel, but also require multiple installations of self-tapping screws, making the installation of gypsum board ceiling and wall panels quite cumbersome. Therefore, a lightweight quick-installation ceiling and wall panel is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lightweight, quick-installation ceiling and wall panel includes multiple main keels, multiple secondary keels, and multiple gypsum ceiling and wall panels. Each secondary keel is equipped with a hanging component for quickly attaching the gypsum ceiling and wall panels. The upper end of each gypsum ceiling and wall panel is fixedly installed with a cylindrical rod and a hemispherical block movably connected to the hanging component. Each secondary keel is equipped with a cover plate for covering the gap between two gypsum ceiling and wall panels. Each secondary keel is equipped with a locking mechanism driven by an upwardly linearly moving hanging component to lock the hanging component, the gypsum ceiling and wall panels, and the secondary keel. Each secondary keel is also equipped with an unlocking mechanism driven by an upwardly linearly moving cover plate to unlock the locking mechanism.

[0007] Preferably, both the main keel and the secondary keel are U-shaped plate structures, the cover plate has a trapezoidal cross-section, and the upper end of the main keel is fixedly installed with a suspension rod that is fixedly connected to the roof.

[0008] Preferably, the hanging component has a connected rectangular groove and a hemispherical groove, and the cylindrical rod and the hemispherical block are slidably fitted into the rectangular groove and the hemispherical groove.

[0009] Preferably, the locking mechanism includes a first spiral-shaped component and a second spiral-shaped component that are slidably fitted onto the secondary keel. The first spiral-shaped component and the second spiral-shaped component each have a movable chamber on their side ends. The two movable chambers share a limiting opening. The two movable chambers are provided with a wedge-shaped block, a limiting rotating plate, and a blocking block. The wedge-shaped block is movably fitted into the limiting opening.

[0010] Preferably, the two movable chambers are slidably fitted with a push block, the lower end of which is fixedly connected to the hanging part. The push block has a placement groove that is slidably connected to the wedge block, and a return spring connected to the wedge block is welded into the placement groove.

[0011] Preferably, a first rotating shaft connected to a limiting rotating plate is rotatably installed in the movable chamber of the first loop-shaped component, a first torsion spring is fixedly fitted on the first rotating shaft, and the blocking block is fixedly connected in the movable chamber of the second loop-shaped component, with the upper end of the blocking block moving against the lower end of the limiting rotating plate.

[0012] Preferably, the unlocking mechanism includes a rotating rocker plate disposed on the secondary keel. The two ends of the rotating rocker plate are respectively provided with a first vertical rod and a second vertical rod that move in a linear manner. The lower end of the first vertical rod is fixedly connected to the cover plate, and the lower end of the second vertical rod is fixedly connected to an unlocking block. The unlocking block has a wedge-shaped surface that moves against the inclined surface of the wedge block.

[0013] Preferably, a mounting truss is fixedly connected to the secondary keel, and a second rotating shaft connected to the rotating rocker is rotatably mounted on the mounting truss. A second torsion spring is fixedly fitted onto the second rotating shaft.

[0014] Preferably, the two ends of the rotating rocker are respectively connected by a first connecting rod and a second connecting rod with pins, and the other ends of the first connecting rod and the second connecting rod are respectively connected by pins to the first vertical rod and the second vertical rod.

[0015] Preferably, the secondary keel is fixedly connected to a first slide rail and a second slide rail, the first vertical rod and the unlocking block are respectively slidably fitted onto the first slide rail and the second slide rail, the lower end of the wedge block is provided with a locking groove, and the limiting rotating plate is movably fitted into the locking groove.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. In this invention, the cylindrical rod and hemispherical block are first installed on the upper part of the gypsum board ceiling panel. Then, the hemispherical block is inserted into the hemispherical groove so that the hemispherical block is above the hanging component. Next, the hemispherical block is pushed towards the rectangular groove and locked onto the upper end of the rectangular groove, so that the gypsum board ceiling panel can be quickly hung on the hanging component. This allows the gypsum board ceiling panel to be pre-connected to the secondary keel, thus eliminating the need for multiple self-tapping screw installations at the lower end of the gypsum board ceiling panel. This simplifies the installation process of the gypsum board ceiling panel and avoids pit damage at the lower end of the gypsum board ceiling panel, thereby maintaining the aesthetic appearance of the lower end of the gypsum board ceiling panel.

[0018] 2. In this invention, after the gypsum ceiling and wall panel is pre-connected to the secondary keel, the gypsum ceiling and wall panel is pushed upwards, causing the wedge block to move upwards until it reaches the limit opening. Under the elastic force of the return spring, the wedge block moves towards the limit opening, allowing the hanging parts and the gypsum ceiling and wall panel to quickly lock with the secondary keel, further simplifying the installation process of the gypsum ceiling and wall panel. After two adjacent gypsum ceiling and wall panels are locked and installed, the cover plate directly covers the gap between the two gypsum ceiling and wall panels to prevent dust from falling from the gap and polluting the indoor environment.

[0019] 3. When it is necessary to unlock the hanging parts and the plaster ceiling wall panel and the secondary keel, the cover plate is pushed upward from below the gap between the two plaster ceiling wall panels. The cover plate causes the other end of the rotating rocker to move the unlocking block downward until the wedge-shaped surface of the unlocking block abuts against the inclined surface of the wedge-shaped block. The wedge-shaped surface provides a component force towards the inclined surface of the wedge-shaped block, causing the wedge-shaped block to move into the active chamber. At the same time, the wedge-shaped block moves downward under the gravity of the plaster ceiling wall panel, so that the wedge-shaped block is in abutting state against the inner wall of the active chamber, thereby quickly releasing the locking state of the hanging parts and the plaster ceiling wall panel and the secondary keel, simplifying the disassembly process of the plaster ceiling wall panel.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] Reference Figures 1-16 A lightweight, quick-installation ceiling and wall panel includes multiple main keels 1, multiple secondary keels 2, and multiple gypsum ceiling and wall panels 3, as shown in the attached diagram. Figure 1 As shown, both the main keel 1 and the secondary keel 2 are U-shaped panel structures. The cover plate 5 has a trapezoidal cross-section. Before the installation of the gypsum ceiling wall panel 3, the main keel 1 is installed to the living room or bedroom ceiling via a hanging rod 6. The secondary keel 2 is connected to the main keel 1 via self-tapping screws, and the main keel 1 and secondary keel 2 are connected in a warp and weft arrangement. The secondary keel 2 is equipped with a hanging bracket 4 for quickly hanging the gypsum ceiling wall panel 3, simplifying the installation process. The secondary keel 2 is also equipped with a useful... A cover plate 5 is provided to cover the gap between two plaster ceiling and wall panels 3 to prevent dust from falling into the room from the gap. A locking mechanism is provided at the secondary keel 2 to connect with the hanging part 4 and to lock the hanging part 4, plaster ceiling and wall panel 3 and secondary keel 2, which further simplifies the installation process of plaster ceiling and wall panel 3. An unlocking mechanism is provided at the secondary keel 2 to connect with the cover plate 5 and to unlock the hanging part 4, plaster ceiling and wall panel 3 and secondary keel 2, so as to simplify the disassembly process of plaster ceiling and wall panel 3.

[0039] Preferably, the cylindrical rod 21 and the hemispherical block 22 are installed at the lower end of the cylindrical rod 21 and the upper end of the gypsum board ceiling 3 using glue or self-tapping screws. The hanging component 4 has a connected rectangular groove 19 and a hemispherical groove 20. Since the size of the hemispherical groove 20 is larger than that of the rectangular groove 19, the hemispherical block 22 can only be moved from the hemispherical groove 20 to the top of the hanging component 4, and then pushed towards the rectangular groove 19, so that the hemispherical block 22 is engaged with the upper end of the rectangular groove 19, so that the gypsum board ceiling 3 and the secondary keel are connected. 2. Pre-connection is performed to avoid multiple self-tapping screw installations at the lower end of the plaster ceiling and wall panel 3, thus simplifying the installation process of the plaster ceiling and wall panel 3 and preventing pit damage at the lower end of the plaster ceiling and wall panel 3, thereby maintaining the aesthetic appearance of the lower end of the plaster ceiling and wall panel 3. After the plaster ceiling and wall panel 3 is installed, putty needs to be applied to the lower end of the plaster ceiling and wall panel 3. If the plaster ceiling and wall panel 3 is installed by self-tapping screws, the putty is prone to cracking at the pits caused by the self-tapping screws, which will affect the final aesthetic appearance of the plaster ceiling and wall panel 3.

[0040] Preferably, the locking mechanism includes a first loop-shaped component 7 and a second loop-shaped component 8 that are slidably fitted onto the secondary keel 2. Both the first loop-shaped component 7 and the second loop-shaped component 8 are loop-shaped plate structures. The upper and lower ends of the first loop-shaped component 7 and the second loop-shaped component 8 are bolted to the secondary keel 2. Both the first loop-shaped component 7 and the second loop-shaped component 8 have movable chambers 9 on their sides. The two movable chambers 9 have a common limiting port 10. The two movable chambers 9 are provided with a wedge-shaped block 11, a limiting rotating plate 12 and a blocking block 13. The wedge-shaped block 11 is movably fitted into the limiting port 10.

[0041] The two movable chambers 9 are slidably fitted with a push block 14. The lower end of the push block 14 is fixedly connected to the hanging piece 4. After the gypsum ceiling panel 3 is pre-connected to the secondary keel 2, the gypsum ceiling panel 3 is pushed upward until the upper end of the gypsum ceiling panel 3 abuts against the lower end of the hanging piece 4, causing the hanging piece 4 and the push block 14 to move upward. The push block 14 has a placement groove 15 that is slidably connected to the wedge block 11. A return spring 16 connected to the wedge block 11 is welded into the placement groove 15. A first rotating shaft 17 connected to the limiting rotating plate 12 is rotatably installed in the movable chamber 9 at the first loop member 7. A first torsion spring 1 is fixedly fitted at the first rotating shaft 17. 8. The upward movement of the long block 14 causes the wedge block 11 to move together. When the inclined surface of the wedge block 11 abuts against the limiting rotating plate 12, the wedge block 11 pushes the limiting rotating plate 12 to rotate upward so that the wedge block 11 passes through the limiting rotating plate 12. When the wedge block 11 moves away from the limiting rotating plate 12, the limiting rotating plate 12 returns to its initial state by the elastic force of the first torsion spring 18. The initial state is that the limiting rotating plate 12 is in an upward tilting state. The blocking block 13 is fixedly connected to the movable chamber 9 at the second loop member 8, and the upper end of the blocking block 13 moves against the lower end of the limiting rotating plate 12 to prevent the limiting rotating plate 12 from rotating downward.

[0042] It should be noted that when the wedge block 11 moves to the limiting port 10, the hanging part 4 and the gypsum ceiling wall panel 3 are locked to the secondary keel 2. After all the gypsum ceiling wall panels 3 are locked, one side of the gypsum ceiling wall panel 3 located on the wall is blocked by the wall, and the other side of the gypsum ceiling wall panel 3 is blocked by the adjacent gypsum ceiling wall panel 3. Both ends of the gypsum ceiling wall panel 3 located at the middle of the roof are blocked by the adjacent gypsum ceiling wall panel 3. Thus, the sides of all the gypsum ceiling wall panels 3 are in a limiting state, making it impossible to push the gypsum ceiling wall panel 3 and the hemispherical block 22 to the hemispherical groove 20, thereby completely locking the gypsum ceiling wall panel 3.

[0043] Preferably, the unlocking mechanism includes a rotating rocker 23 disposed on the secondary keel 2. The two ends of the rotating rocker 23 are respectively provided with a first vertical rod 26 and a second vertical rod 27 that move in a linear manner. The lower end of the first vertical rod 26 is fixedly connected to the cover plate 5. When all the gypsum board ceiling panels 3 are locked, the cover plate 5 is positioned above the gap between the two gypsum board ceiling panels 3 and covers it. The lower end of the second vertical rod 27 is fixedly connected to an unlocking block 28. The unlocking block 28 has a wedge-shaped surface 29 that moves against the inclined surface of the wedge block 11. When the wedge-shaped surface 29 abuts against the inclined surface of the wedge block 11, the wedge-shaped surface 29 provides a downward pressing force perpendicular to the inclined surface of the wedge block 11. This pressing force provides a component force toward the movable chamber 9, causing the wedge block 11 to move into the movable chamber 9 to release the locking state of the hanging piece 4 and the gypsum board ceiling panel 3 with the secondary keel 2.

[0044] Preferably, a mounting truss 30 is fixedly connected to the secondary keel 2. A second rotating shaft 31, connected to the rotating rocker 23, is rotatably mounted on the mounting truss 30. A second torsion spring 32 is fixedly fitted onto the second rotating shaft 31. The two ends of the rotating rocker 23 are respectively pin-connected to a first connecting rod 24 and a second connecting rod 25. The other ends of the first connecting rod 24 and the second connecting rod 25 are respectively pin-connected to a first vertical rod 26 and a second vertical rod 27. A first slide rail 33 and a second slide rail 34 are fixedly connected to the secondary keel 2. The first vertical rod 26 and the unlocking block 28 are slidably fitted onto the first slide rail 33 and the second slide rail 34, respectively. Rail 33 and second slide rail 34 allow the first vertical rod 26, second vertical rod 27, cover plate 5 and unlocking block 28 to move vertically in a straight line. When it is necessary to unlock the hanging part 4 and the plaster ceiling wall panel 3 and the secondary keel 2, the cover plate 5 is pushed upward from below the gap between the two plaster ceiling wall panels 3. The cover plate 5 drives one end of the rotating rocker 23 to deflect upward through the first vertical rod 26 and the first connecting rod 24, and causes the other end of the rotating rocker 23 to deflect downward. The other end of the rotating rocker 23 drives the unlocking block 28 to move downward through the second connecting rod 25 and the second vertical rod 27, so as to release the locked state of the hanging part 4 and the plaster ceiling wall panel 3 and the secondary keel 2.

[0045] When the cover plate 5 is released, the rocker arm 23 is rotated to return to its initial state by the spring force of the second torsion spring 32. The initial state is that the left end of the rocker arm 23 is below and the right end of the rocker arm 23 is above, and the cover plate 5 continues to cover the gap between the two plaster ceiling and wall panels 3. The unlocking block 28 is located above the first loop-shaped piece 7 and the second loop-shaped piece 8.

[0046] It should be noted that when the wedge block 11 moves into the movable chamber 9 due to the component force towards it, the wedge block 11 moves downward under the gravity of the plaster ceiling panel 3, so that the wedge block 11 is in a state of abutment against the inner wall of the movable chamber 9. At the same time, the uppermost limiting rotating plate 12 is movably fitted into the locking groove 35 to prevent the wedge block 11 and the plaster ceiling panel 3 from continuing to fall, thus preventing the unlocked plaster ceiling panel 3 from falling rapidly and injuring construction workers. Furthermore, the unlocked plaster ceiling panel 3 and... There is a height difference between the gypsum board ceiling panel 3 and the hemispherical block 22, so that the gypsum board ceiling panel 3 and the hemispherical block 22 can be pushed to the hemispherical groove 20, so that the gypsum board ceiling panel 3 is separated from the hanging part 4. When it is necessary to restore the initial state of the wedge block 11, the bolt between the first loop part 7 and the second loop part 8 is unscrewed to separate the first loop part 7 and the second loop part 8, and the wedge block 11 is moved to the bottom of the movable chamber 9. Then the first loop part 7 and the second loop part 8 are connected by bolts.

[0047] The functional principle of this invention can be explained through the following operational methods:

[0048] First, install the main keel 1 and the secondary keel 2 to the roof in a latitude and longitude arrangement, and insert the hemispherical block 22 into the hemispherical groove 20 so that the hemispherical block 22 is above the hanging piece 4. Then push the hemispherical block 22 to the rectangular groove 19 and lock the hemispherical block 22 to the upper end of the rectangular groove 19 so that the gypsum ceiling wall panel 3 is hung at the hanging piece 4. Then push the gypsum ceiling wall panel 3 upward, so that the hanging piece 4 drives the push block 14 and the wedge block 11 to move upward. The wedge block 11 abuts against the inner wall of the movable chamber 9 and squeezes the return spring 16 until the wedge block 11 moves to the limit port 10. Under the elastic force of the return spring 16, the wedge block 11 moves to the limit port 10, so that the hanging piece 4 and the gypsum ceiling wall panel 3 are locked with the secondary keel 2. After the two adjacent gypsum ceiling wall panels 3 are installed, the cover plate 5 covers the gap between the two gypsum ceiling wall panels 3.

[0049] When it is necessary to unlock the hanging piece 4 and the plaster ceiling wall panel 3 and the secondary keel 2, push the cover plate 5 upward from below the gap between the two plaster ceiling wall panels 3. The cover plate 5 drives one end of the rotating rocker 23 to deflect upward through the first vertical rod 26 and the first connecting rod 24, and causes the other end of the rotating rocker 23 to deflect downward. The other end of the rotating rocker 23 drives the unlocking block 28 to move downward through the second connecting rod 25 and the second vertical rod 27 until the wedge-shaped surface 29 of the unlocking block 28 abuts against the inclined surface of the wedge block 11. The wedge-shaped surface 29 provides a component force towards the movable chamber 9 on the inclined surface of the wedge block 11, so that the wedge block 11 moves into the movable chamber 9. At the same time, the wedge block 11 moves downward under the gravity of the plaster ceiling wall panel 3, so that the wedge block 11 is in a state of abutting against the inner wall of the movable chamber 9, thereby releasing the locked state of the hanging piece 4 and the plaster ceiling wall panel 3 and the secondary keel 2.

[0050] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
