Description

Technical Field

[0001] This application relates to the field of decorative installation structures, and in particular to a large-scale indoor decorative installation structure and construction method. Background Technology

[0002] With social development and the improvement of living standards, as well as the improvement of building decoration and interior environment, people have higher and higher requirements for interior decoration environment. Various kinds of decorative materials have also appeared on the market, including wood veneer, metal veneer and soft packaging.

[0003] The relevant technologies describe various methods for installing wall finishes, which can be broadly categorized into two types based on the installation method: wet methods and dry methods. Wet methods, also known as wet-laying methods, involve using various fluid materials such as cement mortar and adhesives to bond and fix the base layer (existing wall) to the finish layer, thus completing the wall decoration. Dry methods, also known as dry-hanging methods, involve using installation brackets to install and adjust the base layer and finish layer, thereby completing the wall decoration.

[0004] Compared to wet installation methods, dry installation methods offer advantages such as simpler installation, shorter construction periods, and less on-site pollution, making them the mainstream method for wall panel installation. With the continuous development of wall finishes, large-scale finishes have also emerged. However, existing dry installation methods are not suitable for large finishes. Large panels are often quite heavy, and after a period of time, they may loosen, sag, or deform in the middle, reducing the quality of the finish and affecting the overall aesthetic effect. Summary of the Invention

[0005] In order to improve the instability of large-scale decorative installation structures and enhance the decorative quality and effect of the finish, this application provides an indoor large-scale decorative installation structure and construction method.

[0006] This application provides a technical solution for an indoor large-scale decorative installation structure and construction method, which adopts the following approach:

[0007] An indoor large-scale decorative installation structure includes a decorative panel, multiple connecting components, and multiple supporting members. The decorative panel includes a mounting surface for installation and a decorative surface for decoration. The decorative panel is connected to a base layer through the multiple connecting components and the supporting members.

[0008] The connecting assembly includes a first fixing plate, a second fixing plate, a sleeve, a slide rod, a first compression spring, and a locking tongue. The first fixing plate is connected to the base layer. The axis of the sleeve is perpendicular to the first fixing plate and fixedly connected to it. The second fixing plate is connected to the mounting surface and is arranged along the edge of the mounting surface. The axis of the slide rod is perpendicular to the second fixing plate and fixedly connected to it. The slide rod can slide inside the sleeve. A storage groove is formed on the circumferential surface of the slide rod. One end of the first compression spring is connected to the bottom of the storage groove, and the other end is connected to the locking tongue. A limiting hole is formed on the circumferential surface of the sleeve for the locking tongue to pass through.

[0009] The support includes a mounting plate, a connecting rod, and an abutment plate. The mounting plate is connected to the base layer. The axis of the connecting rod is perpendicular to the mounting plate. One end of the connecting rod is fixed to the mounting plate, and the other end is connected to the abutment plate. When the locking tongue passes through the limiting hole, the abutment plate is in contact with the mounting surface.

[0010] By adopting the above technical solution, during installation, the first fixing plate and the mounting plate are fixed to the base layer respectively. The locking tongue is pressed into the storage groove, and the sliding rod can slide within the sleeve. When the locking tongue moves to the limiting hole, under the action of the first compression spring, the locking tongue pops out from the limiting hole to achieve locking and fixing. At the same time, the abutment plate can abut against the decorative panel. In this way, the multiple connecting components can achieve rapid connection and fixing of the decorative panel. The connection structure is compact and not easy to loosen, ensuring the connection strength and stability at the edge of the decorative panel. Furthermore, the multiple supporting components can support the middle part of the decorative panel, reducing the possibility of deformation in the middle of the decorative panel and effectively preventing the decorative panel from sagging. This improves the instability of large decorative panel installation structures, enhances the decorative quality and effect of the surface, and the installation structure is simple and easy to construct.

[0011] Optionally, the support further includes a sliding seat and a second compression spring. The sliding seat is sleeved on the connecting rod and slidably connected to the connecting rod. The abutment plate is installed at the end of the sliding seat away from the mounting plate. The two ends of the second compression spring are respectively connected to the mounting plate and the sliding seat.

[0012] By adopting the above technical solution, during installation, the decorative panel presses against the abutment plate, and under the action of the second compression spring, the sliding seat can slide on the connecting rod. When the installation is completed, under the action of the second compression spring, the abutment plate can firmly abut against the decorative panel, thereby achieving stable support.

[0013] Optionally, the support member further includes multiple legs and support plates corresponding to each leg. The multiple legs are evenly distributed along the axis of the sliding seat, one end of each leg is connected to the sliding seat, and the support plate is connected to the end of the leg away from the sliding seat. Each support plate is flush with the abutment plate.

[0014] By adopting the above technical solutions, the outriggers can expand the support area, improve the support strength of the support components, and at the same time, they can share the force, thereby further improving the stability of the overall structure.

[0015] Optionally, the connecting assembly further includes a snap-fit ​​component and a hanger. The snap-fit ​​component includes a first end plate, a first connecting plate perpendicular to the first end plate, and a first limiting plate perpendicular to the first connecting plate. The first end plate is connected to the base layer. The hanger includes a second end plate, a second connecting plate perpendicular to the second end plate, and a second limiting plate perpendicular to the second connecting plate. The second end plate is mounted on the mounting surface, and the first limiting plate and the second limiting plate can snap together.

[0016] By adopting the above technical solution, during installation, the snap-fit ​​parts and hangers work together to provide support, further reducing the possibility of the decorative panel sagging after installation.

[0017] Optionally, the length of the latch gradually increases along the direction from the end of the slide rod away from the second fixed plate to the end of the slide rod near the second fixed plate, and when no external force is applied to the latch, the shortest part of the latch is located in the storage slot.

[0018] By adopting the above technical solution, when the slide bar is inserted into the sleeve, as the slide bar slides continuously, the sleeve can automatically press the lock tongue into the storage slot, thus eliminating the need for construction personnel to press the lock tongue, greatly improving convenience.

[0019] Optionally, it also includes multiple main keels and multiple secondary keels. The main keels are arranged vertically, and the multiple main keels are spaced apart. Each main keel is installed on the base layer, and the secondary keels are arranged horizontally and connected between two adjacent main keels.

[0020] By adopting the above technical solution, the overall structure of the main keel and the secondary keel can form a stable installation base. In this way, the first fixing plate and the mounting plate can be directly fixed to the keel, resulting in higher installation strength and stability. At the same time, there is a gap between the decorative panel and the base layer, which can play a role in moisture prevention.

[0021] Optionally, a moisture-proof board is also included, wherein a groove is formed between two adjacent main keels and the secondary keel, and the moisture-proof board is disposed in the groove.

[0022] By adopting the above technical solutions, the moisture-proof board has good moisture-proof properties, can isolate moisture, and can play a moisture-proof role, reducing the possibility of the surface deformation due to moisture and further improving the decoration quality.

[0023] Optionally, it also includes a splicing strip, which includes a base plate, a middle plate, and a top plate. The base plate, the middle plate, and the top plate are in an I-shape. The base plate is connected to the moisture-proof board, and there is a gap between the base plate and the top plate for the decorative panel to be inserted.

[0024] By adopting the above technical solution, each surface is connected and fixed by splicing strips, thus forming a large surface as a whole. In this way, the spliced ​​structure can achieve weight uniformity, thereby further reducing the possibility of the surface sagging due to its own weight.

[0025] Optionally, a cover plate may also be included, which can be engaged with the splicing strip.

[0026] By adopting the above technical solution, after the decorative panel is installed, the cover plate is fastened to the splicing strip to ensure the overall decorative aesthetics of the surface.

[0027] Optionally, a construction method for a large-scale indoor decorative installation structure includes the following steps:

[0028] S1. Preparations before installing the decorative panel;

[0029] S2. Install the main keel and secondary keel;

[0030] S3. Lay out moisture-proof boards and apply sealant;

[0031] S4. Install each first fixing plate and each mounting plate onto the main keel;

[0032] S5. Install each of the second fixing plates onto the decorative panel;

[0033] S6. Install the mounting brackets and connectors;

[0034] S7, Hang decorative panel;

[0035] S8. Install the splicing strip and fix the decorative panel to the splicing strip;

[0036] S9. Following the steps above, complete the hanging of the remaining decorative panels;

[0037] S10. Fasten the cover plate onto the splicing strip.

[0038] By adopting the above technical solution, the overall structure of the main keel and the secondary keel forms the installation frame, and a moisture-proof board is installed on the installation frame to achieve the purpose of moisture prevention, thus forming a stable installation foundation. The installation of snap-fit ​​parts and hangers, through snap-fit ​​parts, hangers, connecting components and support parts, realizes the connection and fixation of the decorative panel and the installation frame. At the same time, the splicing strip is used to complete the splicing assembly of the decorative panel. This can improve the problem of instability of large decorative installation structure, improve the decorative quality and effect of the surface, and the installation structure is simple and easy to construct.

[0039] In summary, this application includes at least one of the following beneficial technical effects:

[0040] 1. This application includes a connecting assembly and a supporting component. The connecting assembly includes a first fixed plate, a sleeve perpendicularly fixed to the first fixed plate, a second fixed plate, and a sliding rod perpendicularly fixed to the second fixed plate. A storage groove is formed on the circumferential surface of the sliding rod. The locking tongue is connected to the bottom of the storage groove via a first compression spring. A limiting hole for the locking tongue to pass through is formed on the circumferential surface of the sleeve. The supporting component includes a mounting plate, a connecting rod, and an abutment plate. The abutment plate is connected to the mounting plate via the connecting rod. During installation, the first fixed plate and the mounting plate are fixed to the base layer respectively. The locking tongue is pressed into the storage groove, allowing the sliding rod to slide within the sleeve. When the locking tongue moves to the limiting hole, under the action of the first compression spring, the locking tongue pops out from the storage groove to achieve a locking engagement. Simultaneously, the abutment plate can be glued to the finish. In this way, by setting multiple connecting components and supporting parts, the connecting components can ensure the connection strength and stability at the edge of the surface, and the supporting parts can support and fix the middle part of the surface, which improves the problem of instability of large surface installation structure, improves the decorative quality and effect of the surface, and the installation structure is simple and easy to construct.

[0041] 2. This application includes a main keel, a secondary keel, and a moisture-proof board. The overall structure of the main keel and the secondary keel forms a stable installation base. In this way, the first fixing plate and the mounting plate can be directly fixed to the keel, resulting in higher installation strength and stability. On the other hand, adding a moisture-proof board between the base layer and the finish can achieve a moisture-proof effect, reduce the possibility of the finish deforming due to moisture, and further improve the decoration quality.

[0042] 3. The large decorative panel in this application adopts a splicing installation structure, that is, each decorative panel is connected and fixed by splicing strips, thus forming a large decorative panel as a whole. In this way, the splicing structure can achieve weight uniformity, thereby further reducing the possibility of the decorative panel sagging due to its own weight. After installation, the cover plate is fastened on the splicing strip to ensure the overall decorative aesthetics of the decorative panel. Attached Figure Description

[0053] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0054] This application discloses an indoor large-scale decorative installation structure, referring to... Figure 1 and Figure 2The large indoor decorative installation structure includes an installation frame 3, a decorative panel 2, multiple connecting components 4 and multiple support members 5. The installation frame 3 is connected to the base layer 1. The decorative panel 2 is connected to the installation frame 3 through the connecting components 4 and the support members 5. The decorative panel 2 includes an installation surface 21 for installation and a decorative surface 22 for decoration, wherein the decorative surface 22 is located on the side of the decorative panel 2 away from the base layer 1.

[0055] The mounting frame 3 forms the installation base for the decorative panel 2. The connecting component 4 can connect and fix the decorative panel 2 to the base layer 1. The connecting component 4 is set along the edge of the decorative panel 2, which can realize the quick connection and fixation of the decorative panel 2. The connection structure is firm and can ensure the connection strength and stability at the edge of the decorative panel 2. The support component 5 can support the decorative panel 2, reduce the possibility of deformation in the middle of the decorative panel 2, and effectively prevent the decorative panel 2 from falling. This improves the problem of instability in the installation structure of large decorative surfaces and improves the decorative quality and effect of the surface.

[0056] Specifically, refer to Figure 2 and Figure 3 The mounting frame 3 includes main keels 31 and secondary keels 32, with multiple main keels 31 and secondary keels 32. The main keels 31 are vertically arranged, and the multiple main keels 31 are evenly spaced, each mounted on the base layer 1. The main keels 31 can be directly fixed to the base layer 1 with bolts, or indirectly fixed with angle brackets or U-shaped mounting clips. In this embodiment, the fixing method of the main keels 31 is not specifically limited. The secondary keels 32 are horizontally arranged and connected between two adjacent main keels 31. Multiple secondary keels 32 are arranged between two adjacent main keels 31, and the multiple secondary keels 32 are evenly spaced along the length of the main keels 31. The secondary keels 32 can be directly welded to the main keels 31, or detachably connected with angle brackets. In this embodiment, the fixing method of the secondary keels 32 is not specifically limited. The overall structure of the main keel 31 and the secondary keel 32 can form a stable installation base. In this way, the connecting component 4 and the support 5 can be directly fixed on the installation frame 3, which is not easily affected by the changes of the base layer 1, and the installation strength and installation stability are higher.

[0057] It should be noted that in this embodiment, the main keel 31 is U-shaped, with the opening located on the side of the main keel 31 facing away from the base layer 1. In this embodiment, the materials of the main keel 31 and the secondary keel 32 are not specifically limited and can be selected according to the actual situation.

[0058] Reference Figure 2 and Figure 3The thickness of the secondary keel 32 is less than that of the main keel 31, meaning that a groove 6 is formed between two adjacent main keels 31 and secondary keels 32, and a moisture-proof board 7 is installed in the groove 6. The moisture-proof board 7 can be connected to the secondary keel 32 by self-tapping screws or by direct glue. In this embodiment, the fixing method of the moisture-proof board 7 is not specifically limited. The moisture-proof board 7 has good moisture-proof properties, can isolate moisture, and can play a moisture-proof role, reducing the possibility of the surface deformation due to moisture. In this embodiment, the moisture-proof board 7 can be made of flame-retardant plywood, magnesium oxide board, etc. Of course, sealant can be applied to the edges of the moisture-proof board 7, which can improve the sealing and also play a reinforcing role.

[0059] Furthermore, referring to Figure 2 and Figure 4 The connecting assembly 4 includes a first fixing plate 41, a second fixing plate 42, a sleeve 43, a sliding rod 44, a first compression spring 45, and a locking tongue 46. The second fixing plate 42 is connected to the mounting surface 21 and is positioned along the edge of the mounting surface 21. The axis of the sliding rod 44 is perpendicular to and fixedly connected to the second fixing plate 42. The sliding rod 44 can slide within the sleeve 43. A storage groove 47 is formed on the circumferential surface of the sliding rod 44. One end of the first compression spring 45 is connected to the bottom of the storage groove 47, and the other end is connected to the locking tongue 46. The first fixing plate 41 is connected to the main keel 31. The axis of the sleeve 43 is perpendicular to and fixedly connected to the first fixing plate 41. The sleeve 43 extends from the opening of the main keel 31, and a limiting hole 48 for the locking tongue 46 to pass through is formed on the circumferential surface of the sleeve 43. In this embodiment, the first fixing plate 41 can be fixed by welding or detachably connected by self-tapping screws or other means. The second fixing plate 42 can be fixed with self-tapping screws.

[0060] During installation, insert the slide bar 44 into the sleeve 43 and slide it slowly. Press the latch 46 so that the latch 46 is fully inserted into the storage groove 47 so that the slide bar 44 can continue to slide. When the latch 46 moves to the limiting hole 48, under the action of the first compression spring 45, the latch 46 can pass through the limiting hole 48. At this time, the latch 46 plays the role of locking, and the slide bar 44 can no longer slide. In this way, the decorative panel 2 and the main keel 31 are fixed. The connection method is simple and easy to disassemble.

[0061] Specifically, along the direction from the end of the slide bar 44 away from the second fixed plate 42 to the end of the slide bar 44 near the second fixed plate 42, the length of the latch 46 gradually increases, that is, the top of the latch 46 forms an inclined surface. When no external force is applied to the latch 46, the shortest part of the latch 46 is located in the storage groove 47. When the slide bar 44 is inserted into the sleeve 43, as the slide bar 44 slides continuously, the sleeve 43 can automatically press the latch 46 into the storage groove 47. During installation, this eliminates the need for construction personnel to press the latch 46, greatly improving the convenience of installation.

[0062] Specifically, refer to Figure 2 and Figure 5 The support member 5 includes a mounting plate 51, a connecting rod 52, and an abutment plate 53. The mounting plate 51 is connected to the main keel 31. The axis of the connecting rod 52 is perpendicular to the mounting plate 51. One end of the connecting rod 52 is fixed to the mounting plate 51, and the connecting rod 52 extends from the opening of the main keel 31. The other end is connected to the abutment plate 53. When the latch 46 passes through the limiting hole 48, the abutment plate 53 can just fit against the mounting surface 21. In this embodiment, the mounting plate 51 can be fixed by welding or detachably connected by self-tapping screws or the like. The support member 5 can be arranged at the edge and middle of the decorative panel 2. The support member 5 can play a supporting role and reduce the possibility of deformation of the decorative panel 2.

[0063] It should be noted that the number of support members 5 and connecting components 4 can be adjusted according to the actual working conditions and the actual size of the decorative panel 2. Of course, depending on the actual situation, the mounting plate 51 and the first fixing plate 41 can be fixed on the base layer 1. In this embodiment, the example of fixing the mounting plate 51 and the first fixing plate 41 to the main keel 31 is used for illustration only.

[0064] The support member 5 also includes a sliding seat 54 and a second compression spring 55. The sliding seat 54 is sleeved on and slidably connected to the connecting rod 52. The abutment plate 53 is installed at the end of the sliding seat 54 away from the mounting plate 51. The two ends of the second compression spring 55 are respectively connected to the mounting plate 51 and the sliding seat 54. When the installation is completed, under the action of the second compression spring 55, the abutment plate 53 can firmly abut against the decorative panel 2, improving the connection strength and thus achieving stable support.

[0065] The support member 5 also includes multiple legs 56 and corresponding support plates 57. The multiple legs 56 are evenly distributed along the axis of the sliding seat 54, with one end of each leg 56 connected to the sliding seat 54. The support plate 57 is connected to the end of the leg 56 away from the sliding seat 54, and each support plate 57 is flush with the abutment plate 53. In this embodiment, there are two legs 56. Of course, the number of legs 56 can be adjusted according to actual needs. The legs 56 can expand the support area, improve the support strength of the support member 5, and also distribute the force, further improving the stability of the overall structure.

[0066] It should be noted that the sides of the support plate 57 and the abutment plate 53 closest to the decorative panel 2 can be specially treated, such as by applying adhesive or anti-slip treatment. Anti-slip treatment can involve processing anti-slip textures or using anti-slip plates. This increases the friction between the support plate 57 and the abutment plate 53 and the decorative panel 2, achieving better anti-sagging.

[0067] Reference Figure 6 and Figure 7 To further reduce the possibility of the decorative panel 2 sagging, the connecting assembly 4 also includes a snap-fit ​​member 8 and a hanger 9. Specifically, the snap-fit ​​member 8 includes a first end plate 81, a first connecting plate 82 perpendicular to the first end plate 81, and a first limiting plate 83 perpendicular to the first connecting plate 82. The first end plate 81 is connected to the main keel 31. The hanger 9 includes a second end plate 91, a second connecting plate 92 perpendicular to the second end plate 91, and a second limiting plate 93 perpendicular to the second connecting plate 92. The second end plate 91 is mounted on the mounting surface 21. The first end plate 81, the first connecting plate 82, and the first limiting plate 83 form a gap for the second limiting plate 93 to be inserted. Similarly, the second end plate 91, the second connecting plate 92, and the second limiting plate 93 form a gap for the first limiting plate 83 to be inserted. The first end plate 81 can be fixed to the main keel 31 by welding or by detachable connection using screws or other means. The second end plate 91 can be detachably connected using self-tapping screws or other means. Of course, when the decorative panel 2 is made of metal, it can also be directly welded and fixed.

[0068] During installation, the second limiting plate 93 is inserted into the gap formed by the first end plate 81, the first connecting plate 82, and the first limiting plate 83. At the same time, the first limiting plate 83 is also inserted into the gap formed by the second end plate 91, the second connecting plate 92, and the second limiting plate 93. In this way, the first connecting plate 82 can support the second limiting plate 93, and the first limiting plate 83 can support the second connecting plate 92, which further reduces the possibility of the decorative panel 2 sagging after installation.

[0069] Reference Figure 2 and Figure 8To improve the ease of installation for large indoor decorative panels, a splicing assembly method can be adopted. Specifically, a splicing strip 10 is connected to the base layer 1, and multiple decorative panels 2 can be combined through the splicing strip 10 to meet the installation requirements. The splicing strip 10 includes a base plate 101, a middle plate 102, and a top plate 103. The base plate 101, middle plate 102, and top plate 103 are in an I-shape. The base plate 101 can be directly or indirectly connected to the base layer 1. In this embodiment, the base plate 101 is fixed to the moisture-proof board 7. There is a gap between the base plate 101 and the top plate 103 for the decorative panels 2 to be inserted. During installation, the splicing strip 10 is inserted into the decorative panel 2, and the splicing strip 10, decorative panel 2, and moisture-proof board 7 are fastened together with screws or self-tapping screws. Of course, in order to ensure the aesthetic appearance of the decorative panel 2, that is, to cover the screws or self-tapping screws and other fasteners, this application also provides a cover plate 11, which can be fastened to the top plate 103, and is convenient to install and remove.

[0070] The implementation principle of a large-scale indoor decorative panel installation structure according to an embodiment of this application is as follows: During installation, the main keel 31, secondary keel 32, and moisture-proof board 7 are installed and fixed. The first fixing plate 41, the first end plate 81, and the mounting plate 51 are respectively fixed to the main keel 31. The second fixing plates 42 and the second end plates 91 are respectively installed on the decorative panel 2. The second limiting plate 93 is inserted into the gap formed by the first end plate 81, the first connecting plate 82, and the first limiting plate 83. The sliding rod 44 is aligned with the sleeve 43 and slides. When the locking tongue 46 moves to the limiting hole 48, under the action of the first compression spring 45, the locking tongue 46 pops out from the storage groove 47 to achieve locking and fixing. At the same time, the support member 5 just plays a supporting role. This improves the instability problem of large-scale decorative panel installation structures and enhances the decorative quality and effect of the surface.

[0071] This application also discloses a construction method for a large-scale indoor decorative installation structure. (Refer to...) Figure 9 The construction method for large-scale indoor decorative installation structures includes the following steps:

[0072] S1. Preparations before installing decorative panel 2;

[0073] The preparatory work includes leveling the base layer 1, marking the base layer 1, and moisture-proofing the base layer 1.

[0074] Leveling the base layer 1 involves removing any protrusions to facilitate the subsequent installation of the main keel 31 and secondary keel 32, while also ensuring the flatness of the decorative panel 2 during installation. A laser level can be used for leveling the base layer 1. Leveling the base layer 1 is a procedure well-known to those skilled in the art, and will not be described in detail in this embodiment.

[0075] The marking of the base layer 1 is used to delineate the installation area, determine the installation positions of each main keel 31 and secondary keel 32, and determine the splicing scheme of the decorative panel 2. Additionally, holes are drilled in the base layer 1 according to the marking to fix the main keels 31. Marking the base layer 1 is a procedure well-known to those skilled in the art, and will not be described in detail in this embodiment.

[0076] Decorative panel 2 is prone to deformation once it gets damp. Moisture-proofing the base layer 1 can effectively prevent moisture from escaping and protect the decorative panel 2. Moisture-proofing the base layer 1 can be done by applying moisture-proof coating or waterproof mortar to the base layer 1.

[0077] S2. Install the main keel 31 and the secondary keel 32;

[0078] The main keel 31 can be directly fixed to the base layer 1 with bolts, or indirectly fixed with angle brackets or U-shaped mounting clips. The main keel 31 should be laid out according to the previously marked lines. The secondary keel 32 can be directly welded to the main keel 31, or it can be detachably connected with angle brackets.
