Description

Technical Field

[0001] The present invention relates to the technical field of partition wall systems, in particular to a prefabricated assembled indoor partition wall system with a finishing layer that can be installed flat. Background Art

[0002] In the field of architectural decoration, interior partition walls are widely used in various construction projects, such as commercial places, residential and office spaces, as components for space division and function definition. In these scenarios, interior partition walls have the characteristics of adjustment to adapt to the ever-changing needs of space use. However, traditional devices lack the ability to quickly disassemble and assemble. When the space layout needs to be replanned, since traditional partition walls are mostly one-piece molding or complex fixed installation methods, the removal work is extremely cumbersome and often requires the use of a large number of tools and consumes a lot of manpower and time. During the removal process, wall components are easily damaged and difficult to reuse, resulting in a waste of resources. When reassembling new partition walls, the installation process is also complicated and time-consuming. This not only seriously affects construction efficiency and leads to extended project schedules, but also significantly increases labor and time costs, thereby pushing up the construction cost of the entire project. In addition, traditional devices are usually fixed structures and lack height adjustment functions. During the installation process, if the ground is uneven or there are slight deviations in the floor height, it is difficult to connect the unit wall and the top purlin because the height of the partition wall cannot be adjusted. This will not only lead to a decrease in the stability of the overall structure of the partition wall, but also in daily use, when affected by external forces such as human activities, temperature changes, and the building's own settlement, the partition wall is prone to shaking and displacement, causing cracks on the wall surface, affecting the appearance and usability, and may also cause safety risks. Summary of the Invention

[0003] In view of the above-mentioned problems, in combination with the first aspect of the present invention, an embodiment of the present invention provides a prefabricated and assembled indoor partition wall system with a finishing layer that can be installed flatly, the device comprising:

After a brief inspection and maintenance, these components can be reused to construct partition walls in other construction projects or locations. This maximizes the value of the materials used, minimizes environmental impact, and enhances the device's resource recycling and environmental protection capabilities.

[0033] The present invention will be described in detail below with reference to the accompanying drawings;

[0034] like Figures 1 to 9 、 Figures 13 to 15 、 Figure 18As shown, the present invention provides a prefabricated, assembled interior partition wall system with a tileable finish layer. The system comprises multiple sets of unit walls, along with floor runners 11, ceiling runners 12, and multiple sets of wall bodies. The floor runners 11 and ceiling runners 12 are positioned between the multiple sets of wall bodies, with the floor runners 11 at the bottom and the ceiling runners 12 at the top. They provide upper and lower position limits and support for the multiple sets of wall bodies. The multiple unit walls, located between the floor runners 11 and ceiling runners 12, constitute the main body of the partition wall.

[0035] Each of the multiple unit walls includes multiple sets of decorative panels 13 and multiple sets of vertical purlins 14. The multiple sets of decorative panels 13 are connected by multiple sets of vertical purlins 14. The vertical purlins 14 serve as a skeletal support, allowing the decorative panels 13 to be combined to form the unit wall structure. A filling cavity is formed between the multiple sets of vertical purlins 14 and the multiple sets of decorative panels 13, which can be filled with sound insulation, heat insulation, and other materials to improve the performance of the partition wall. Each of the multiple sets of vertical purlins 14 is provided with multiple sets of insertion slots 15, which are evenly spaced from top to bottom. The multiple sets of vertical purlins 14 are also provided with multiple sets of mounting holes. The tops of the multiple sets of vertical purlins 14 are provided with multiple sets of U-shaped snap-in slots 22 for connecting to the top purlin 12. By setting up multiple groups of plug-in slots 15, multiple groups of unit walls can be detachably connected, which facilitates the rapid assembly and disassembly of partition walls, improves construction efficiency, and facilitates the later modification or rearrangement of partition walls. Multiple groups of mounting holes can be used to install other accessories to increase the function of partition walls.

[0036] The U-shaped snap-fitting groove 22 is adapted to the connection structure of the top keel 12 to realize the connection between the unit wall and the top keel 12. The floor keel 11 is provided with multiple sets of fixing bolts for fixing the floor keel 11 to the ground to ensure the stability of the bottom of the partition wall. The floor keel 11 is U-shaped. This shape is conducive to fit with the ground and provides space for internal structure. Multiple sets of installation adjustment holes are provided on both sides of the floor keel 11, and multiple sets of height adjustment components are symmetrically arranged on both sides of the floor keel 11.

[0037] The multiple sets of height adjustment assemblies each include multiple sets of protrusions 16, which are respectively located on both sides of the inner walls of the multiple sets of installation adjustment holes. Multiple sets of limit slots 17 are provided on the multiple sets of protrusions 16, and a lifting plate 18 is provided between the multiple sets of protrusions 16. The protrusions 16 cooperate with the installation adjustment holes to provide an installation base for the height adjustment assembly, so that the height adjustment assembly can be stably installed on the ground keel 11. The limit slots 17 provide guidance and limit for the movement of the lifting plate 18, so that the lifting plate 18 can only move in a specific direction, ensuring the stability of the adjustment process. The lifting plate 18 is used to support one end of the unit wall. By adjusting its height, the height of the unit wall can be adjusted. The multiple sets of height adjustment assemblies also include multiple sets of threaded adjustment brackets 19, which are located between the multiple sets of protrusions 16. The multiple sets of lifting plates 18 are connected to the multiple sets of threaded adjustment brackets 19, and both ends of the multiple sets of lifting plates 18 are slidably connected to the multiple sets of limit slots 17. By rotating the threaded adjustment bracket 19, the lifting plate 18 can be driven to slide within the limit slot 17, thereby adjusting the height of the lifting plate 18. This arrangement allows users to adjust the height of the unit wall according to the actual floor flatness or needs, improving the adaptability of partition wall installation. The multiple sets of protrusions 16 are each provided with fastening bolts 21. The multiple sets of fastening bolts 21 pass through the multiple sets of protrusions 16 and connect to one end of the multiple sets of vertical keels 14. Multiple sets of operating holes for adjusting the fastening bolts 21 are provided along both sides of the ground keel 11. The multiple sets of unit walls are each detachably connected to the multiple sets of lifting plates 18 at one end.

[0038] The fastening bolts 21 connect the protrusions 16 to the vertical keels 14, ensuring the connection between the height adjustment assembly and the unit wall. The operating holes make it easy for users to operate the fastening bolts 21, making it easier to operate when adjustment or removal is required. The detachable connection between the unit wall and the lifting plate 18 makes it more convenient to install, remove, or adjust the unit wall. The top keel 12 is in an inverted U shape, echoing the shape of the floor keel 11. This shape helps to fit with the ceiling and limit the top of the unit wall. Multiple groups of connection holes for connecting to the wall are provided on one side of the top keel 12. Each group of connection holes is provided with fixing bolts. These fixing bolts can be used to fix the top keel 12 to the wall body, enhancing the stability of the top of the partition wall. A plurality of sets of card joints are provided at one end of the top keel 12, and the plurality of card joints are detachably connected to the plurality of sets of U-shaped card grooves 22, which further strengthens the connection between the top keel 12 and the unit wall and is convenient for disassembly. Rubber pads 23 are provided on one side of the floor keel 11 and the top keel 12. The setting of the rubber pads 23 can reduce the friction and collision noise between the partition wall and the ground and ceiling, and at the same time play a certain sealing role, thereby improving the sound insulation and dustproof performance of the partition wall.

[0039] like Figures 6 to 13 、 Figure 16 、 Figure 17 As shown: multiple sets of fixing bolts are provided on the ground keel 11. By connecting the fixing bolts to the ground, the ground keel 11 is fixed to the ground, so that the bottom of the partition wall is supported. The ground keel 11 is U-shaped. This shape makes the ground keel 11 fit the ground and provides space for the installation of internal components. Multiple sets of installation adjustment holes are provided on both sides of the ground keel 11. Multiple sets of height adjustment components are symmetrically arranged on both sides. The installation adjustment holes provide installation positions for the height adjustment components. The symmetrical arrangement ensures balanced adjustment force. The multiple sets of height adjustment components each include multiple sets of protrusions 16. The multiple sets of protrusions 16 are respectively located on both sides of the inner walls of the multiple sets of installation adjustment holes. The protrusions 16 are connected to both sides of the inner walls of the installation adjustment holes to achieve the installation of the protrusions 16 on the ground keel 11. Multiple sets of limit slots 17 are provided on the multiple sets of protrusions 16, and lifting plates 18 are provided between the multiple sets of protrusions 16. The limiting slots 17 provide guidance and positioning for the movement of the lifting plate 18, which is used to support one end of the unit wall. The multiple height adjustment assemblies also include multiple sets of threaded adjustment brackets 19, which are located between the multiple sets of protrusions 16. Each of the multiple lifting plates 18 is connected to the multiple sets of threaded adjustment brackets 19, and both ends of the multiple lifting plates 18 are slidably connected to the multiple sets of limiting slots 17. By rotating the threaded adjustment brackets 19, the lifting plates 18 are driven to slide within the limiting slots 17 via a threaded transmission, allowing the height of the lifting plates 18 to be adjusted to meet the different height requirements of the unit walls. Each of the multiple sets of protrusions 16 is provided with fastening bolts 21, which pass through the multiple sets of protrusions 16 and connect to one end of the multiple sets of vertical keels 14. Multiple sets of operating holes for adjusting the fastening bolts 21 are provided along both sides of the ground keel 11. Each end of the multiple unit walls is detachably connected to the multiple sets of lifting plates 18. The fastening bolts 21 connect the protrusions 16 to the vertical keels 14 , and the operating holes facilitate adjustment of the fastening bolts 21 . The detachable connection between the unit wall and the lifting plate 18 facilitates installation, disassembly and adjustment of the partition wall.

[0040] Specific usage and effects of the present invention:

[0041] When using the device, the user first encounters the U-shaped floor keel 11, which is equipped with multiple sets of fixing bolts. This keel 11 serves as the basic support structure at the bottom of the partition wall, supporting the entire wall. It can accommodate multiple sets of height adjustment components symmetrically arranged on either side of the keel, providing mounting locations for these components. Multiple sets of mounting holes on either side of the keel 11 serve as mounting locations for the height adjustment components and provide corresponding locations for the installation of protrusions 16. The protrusions 16 in the multiple height adjustment components are located on either side of the inner walls of the mounting holes. Multiple sets of position-limiting slots 17 on the protrusions 16 guide and limit the movement of a lifting plate 18. The lifting plate 18, located between the protrusions 16 and directly connected to the unit wall, supports one end of the unit wall. Both ends of the lifting plate 18 are slidably connected to the position-limiting slots 17, allowing the lifting plate 18 to move stably between the protrusions 16, guided by the position-limiting slots 17.

[0042] The threaded adjustment bracket 19 in the height adjustment assembly is located between the multiple groups of bumps 16 and connected to the lifting plate 18. When the user rotates the threaded adjustment bracket 19, the lifting plate 18 can be driven to slide up and down within the limit slot 17 through the principle of thread transmission, thereby adjusting the height of the lifting plate 18 to adapt to different floor flatness and height requirements. The fastening bolts 21 provided through the multiple groups of bumps 16 serve to connect the bumps 16 to one end of the vertical keel 14. The multiple groups of operating holes for adjusting the fastening bolts 21 are provided along both sides of the floor keel 11, making it convenient for the user to tighten and loosen the fastening bolts 21, thereby maintaining the connection between the bumps 16 and the vertical keel 14 when installing, adjusting, or disassembling the partition wall.

[0043] The unit walls are composed of multiple sets of decorative panels 13 connected to multiple sets of vertical keels 14. Multiple sets of insertion slots 15 are arranged equidistantly from top to bottom on one side of the vertical keels 14. These insertion slots 15 enable removable connections between the unit walls. By aligning the insertion slots 15 on one set of vertical keels 14 with the corresponding insertion slots 15 on another set of vertical keels 14 and inserting them, the unit walls can be quickly connected, making the assembly of the partition wall more convenient. Multiple sets of mounting holes on the side of the vertical keels 14 can be used to install other accessories to enhance the functionality of the partition wall. Multiple sets of U-shaped snap-in slots 22 on the top of the vertical keels 14 are used for removable connection with multiple sets of snap-in connectors along one end of the top keel 12. The top keel 12 is in an inverted U-shape, with multiple sets of wall-connecting holes on one side. These holes are connected to the wall using fixing bolts installed above, securing the top of the partition wall. Rubber pads 23 installed along the side of the floor keel 11 and the top keel 12 reduce friction and collision noise between the partition wall and the floor and ceiling, while also enhancing sealing performance and improving the partition wall's soundproofing and dustproofing. The filling cavity formed between the vertical keel 14 and the decorative panel 13 can be filled with materials such as soundproofing cotton and thermal insulation foam according to actual needs, further improving the partition wall's sound and thermal insulation performance.

[0044] Instructions for use: When using this device, the user should first confirm that the construction site environment meets the requirements and prepare all components and installation tools. Next, place the U-shaped ground keel 11 with multiple sets of fixing bolts at a predetermined position on the ground, and fix it to the ground with fixing bolts 0. The installation adjustment holes on both sides provide positions for the subsequent installation of height adjustment components. Rubber pads 23 are installed on one side of the ground keel 11 and the top keel 12, or the filling cavity between the vertical keel 14 and the decorative panel 13 can be filled with materials as needed. Subsequently, the protrusions on the inner walls of both sides of the ground keel 11 and the adjustment holes on the ground keel 11 are used together, and the limit slots 17 on the protrusions 16 are used to guide and limit the lifting plate 18. The lifting plate 18 is placed between the protrusions 16 and the lifting plate 18 is placed between the protrusions 16. Its two ends are slidably connected to the limit slots 17. Then, multiple sets of threaded adjustment brackets 19 are installed between the protrusions 16 and connected to the lifting plate 18. The threaded adjustment brackets 19 are rotated according to the flatness and height of the ground. After the height of the lifting plate 18 is adjusted by thread transmission, multiple sets of decorative panels 13 are connected to the unit wall through the vertical keel 14. The plug slots 15 arranged evenly from top to bottom on one side of the vertical keel 14 are used to achieve detachable connection between the unit walls. The mounting holes on the vertical keel 14 can be used to add accessories. After the unit wall is assembled, one end of it is detachably connected to the height-adjusted lifting plate 18. At the same time, the inverted U-shaped top keel 12 is connected to the wall body through the fixing bolts on one side of the connection hole. The clamping joint at one end of it is detachably connected to the U-shaped clamping slot 22 at the top of the vertical keel 14, completing the top fixing of the partition wall. After the installation is completed, the skirting board is installed around the side of the ground keel and connected to it with a connector, thereby modifying the surface and making the wall more beautiful.

[0045] It should be noted that in order to simplify the description of the present invention and thus help understand one or more embodiments of the invention, in the foregoing description of the embodiments of the present invention, multiple features are sometimes combined into one embodiment, figure or description thereof.
