Detailed Implementation

[0011] This application describes several embodiments, but these descriptions are exemplary and not restrictive, and it will be apparent to those skilled in the art that many more embodiments and implementations are possible within the scope of the embodiments described herein. The embodiments, features, and elements disclosed in this application can also be combined with any conventional features or elements to form unique inventive solutions.

[0012] Please refer to the instruction manual appendix. Figures 1 to 11 The diagram shows a structural schematic of a prefabricated wall according to an exemplary embodiment of this application. Figures 1 to 3 , Figures 5 to 8 As shown, this application embodiment provides a magnetically assembled wall, including multiple vertical keels 1, multiple inner substrates 2, and decorative panels 4.

[0013] Among them, such as Figure 1 , Figure 6 and Figure 9 As shown, multiple vertical keels 1 are spaced apart along a first direction, which is the length direction of the prefabricated wall. The length extension direction of each vertical keel 1 extends along a second direction, which is the height direction of the prefabricated wall. Each vertical keel 1 has a connector groove 11 at both ends along a third direction, which is the thickness direction of the prefabricated wall. The first direction, the second direction, and the third direction are perpendicular to each other.

[0014] like Figure 1 and Figure 6As shown, the plurality of inner layer substrates 2 include a first inner layer substrate 21 and a second inner layer substrate 22, which are spaced apart along a third direction. Each first inner layer substrate 21 has its two ends along the first direction connected to a first end 18 of an adjacent vertical keel 1 along the third direction. Each second inner layer substrate 22 has its two ends along the first direction connected to a second end 19 of an adjacent vertical keel 1 along the third direction. At least one end of each of the first inner layer substrates 21 and 22 along the first direction is inserted into a corresponding insertion slot 11. The first end 18 and the second end 19 of the vertical keel 1 are both partially located outside the inner layer substrates 2. Figure 3 , Figure 4 and Figure 8 As shown, the portion of the vertical keel 1 located outside the inner substrate 2 is provided with a magnet 51.

[0015] like Figure 1 and Figure 6 As shown, the decorative panel 4 includes a first decorative panel 41 and a second decorative panel 42. The first decorative panel 41 is mounted to the side of the first inner layer substrate 21 opposite to the second inner layer substrate 22, and the second decorative panel 42 is mounted to the side of the second inner layer substrate 22 opposite to the first inner layer substrate 21. Figure 5 As shown, both the first decorative panel 41 and the second decorative panel 42 have magnetic attraction components 52 on the side facing the inner substrate 2. The magnetic attraction components 52 are made of ferromagnetic material. The first decorative panel 41 and the second decorative panel 42 are magnetically attracted to the vertical keel 1 by the corresponding magnetic attraction components 52 and magnets 51.

[0016] Specifically, Figure 1 , Figures 5 to 9 , Figure 11 The first direction shown is the length direction of the prefabricated wall, the second direction is the height direction of the prefabricated wall, and the third direction is the thickness direction of the prefabricated wall. The length, height, and thickness directions of the multiple inner substrates 2 and decorative panels 4 are the same as the length, height, and thickness directions of the magnetically assembled wall, respectively. Figures 1 to 3 An embodiment of the prefabricated wall of this application is shown. Figures 6 to 8 Another embodiment of the prefabricated wall structure of this application is shown, in which the structures of the vertical keel 1 differ between the two embodiments. Figure 1 The middle adopts 3U vertical keel 1', Figure 6 The middle adopts 5U vertical keel 1".

[0017] The prefabricated wall structure provided in this application embodiment has a vertical keel 1 with both ends partially located outside the inner substrate 2 along a third direction, and the portion of the vertical keel 1 located outside the inner substrate 2 is provided with a magnet 51. Both the first decorative panel 41 and the second decorative panel 42 have magnetic attraction components 52 on their sides facing the inner substrate 2. The magnetic attraction components 52 are made of ferromagnetic material. Thus, through the magnetic attraction of the corresponding magnetic attraction components 52 and magnets 51, the first decorative panel 41 and the second decorative panel 42 can be fixed to the two end faces of the vertical keel 1 along a third direction, respectively. During the construction and assembly process of the prefabricated wall structure of this application, by aligning and magnetically connecting the magnetic attraction components 52 of the decorative panel 4 with the magnets 51 of the vertical keel 1, the decorative panel 4 can be quickly installed onto the outer surface of the inner substrate 2. Furthermore, by releasing the magnetic attraction between the magnetic attraction components 52 and magnets 51 (for example, by pushing the decorative panel 4 along the first direction to weaken the magnetic attraction between the magnetic attraction components 52 and magnets 51), the decorative panel 4 can be quickly and easily removed. Compared to the existing construction methods for prefabricated walls, which require frequent nailing and unnailing operations to install and remove decorative panels 4, the prefabricated wall system of this application offers a simple, convenient, efficient, and low-labor-intensive method for assembling and removing decorative panels 4.

[0018] Furthermore, instead of nailing the outer surface of the decorative panel 4, a magnetic fastening component 52 is provided on the surface of the decorative panel 4 facing the inner substrate 2. This avoids damaging the outer surface of the decorative panel 4, making the outer surface of the decorative panel 4 neat and beautiful, thereby improving the aesthetics of the prefabricated wall of this application.

[0019] like Figure 2 and Figure 7 As shown, at least one end of the inner substrate 2 along the first direction is inserted into the insertion slot 11 of the vertical keel 1, and the inner substrate 2 is inserted and connected to the vertical keel 1. This makes the installation of the inner substrate 2 convenient and quick. The structure of the two ends of the vertical keel 1 along the third direction can not only insert and connect the inner substrate 2, but also magnetically connect the decorative panel 4, so that the keel structure of the vertical keel 1 can be fully utilized, which helps to simplify the composition structure of the vertical keel 1 of this application.

[0020] In one exemplary embodiment, such as Figure 4 , Figure 3 and Figure 8 As shown, the prefabricated wall also includes a mounting plate 53, to which magnets 51 are mounted. The mounting plate 53 is fixed to both ends of the vertical keel 1 along a third direction by fasteners (not shown in the figure).

[0021] Specifically, such as Figure 3 and Figure 8As shown, the mounting plate 53 is located on the surface of the vertical keel 1 facing the decorative panel 4. The vertical keel 1 is typically made of light steel. The magnet 51 is located on the surface of the mounting plate 53 facing the decorative panel 4. Figure 4 As shown, the mounting plate 53 is provided with mounting holes 55. Fasteners (such as self-tapping screws) pass through the mounting holes 55 and are screwed into the vertical keel 1, so that the magnet 51 is installed to the first end 18 and the second end 19 of the vertical keel 1.

[0022] The magnet 51 is fixed to the vertical keel 1 by the mounting plate 53 and fasteners, which facilitates the quick installation, disassembly and reuse of the magnet 51 and the mounting plate 53.

[0023] In one exemplary embodiment, such as Figure 2 As shown, a magnet 51 is provided on the side of the inner substrate 2 facing the decorative panel 4. Figure 2 Not shown in the image; see details below. Figure 4 As shown), magnet 51 is mounted to mounting plate 53, and mounting plate 53 is fixed to inner substrate 2 by fasteners 54 passing through inner substrate 2 and vertical keel 1.

[0024] The decorative panel 4 is magnetically attached to the inner substrate 2 and / or the vertical keel 1.

[0025] Specifically, the inner substrate 2 is usually made of gypsum board. If fasteners are used to fix the mounting plate 53 through the mounting plate 53 and the gypsum board, the magnetic attraction will cause the gypsum board to crack and break at the fastener location after a long period of time. This application uses fasteners to fix the mounting plate 53 to the inner substrate 2 through the mounting plate 53, the gypsum board, and the metal vertical keel 1. In this way, the mounting plate 53 is more firmly fixed, and the gypsum board location where it is driven into the fastener is less likely to be damaged and cracked.

[0026] In this embodiment, in addition to the magnets 51 provided on the vertical keel 1, the end of the inner substrate 2 near the vertical keel 1 is also provided with magnets 51. In this way, the decorative panel 4 can be magnetically attracted to the magnets 51 located on multiple vertical keels 1, the decorative panel 4 can also be magnetically attracted to the magnets 51 located on multiple inner substrates 2, and the decorative panel 4 can also be magnetically attracted to the magnets 51 located on both the inner substrate 2 and the vertical keel 1. This expands the installation methods of the decorative panel 4, so that decorative panels 4 with different lengths along the first direction can be installed.

[0027] In one exemplary embodiment, there are multiple magnets 51 and mounting plates 53; the magnets 51 and mounting plates 53 are distributed along the second direction at a spacing of less than or equal to 600 mm.

[0028] Specifically, multiple magnets 51 and mounting plates 53 are provided, and the multiple magnets 51 and mounting plates 53 are distributed at intervals of less than or equal to 600 mm along the second direction. In this way, the number of magnetic attraction components 52 on the decorative panel 4 and the magnets 51 on the vertical keel 1 and / or the inner substrate 2 is large, the magnetic attraction force is large, and the decorative panel 4 is installed more firmly.

[0029] The spacing between the multiple magnets 51 along the second direction is less than or equal to 600 mm. This small spacing between the multiple magnets 51 along the second direction makes it less likely that bulges and unevenness will occur after the decorative panel 4 is installed.

[0030] In one exemplary embodiment, such as Figure 5 As shown, the magnetic attraction component 52 includes multiple iron pieces, which are correspondingly arranged with the magnet 51, wherein: The iron sheets are located at both ends and the middle of each decorative panel 4 along the first direction; and / or, Multiple iron plates protrude from the decorative panel 4 at a height of 0.8 mm to 2 mm; and / or, The upper surfaces of the iron sheets located on the same decorative panel 4 facing the inner substrate 2 are all flush.

[0031] Specifically, the iron sheet protrudes from the decorative panel 4 by 0.8 mm to 2 mm, which makes the magnetic attraction between the magnet 51 and the iron sheet greater. This avoids the magnetic attraction between the magnet 51 and the iron sheet being significantly reduced due to the iron sheet being too thin, and helps to improve the overall strength and stability of the decorative wall.

[0032] The iron sheets on the same decorative panel 4 are all flush with the upper surface of the inner substrate 2, so that the appearance is flat after each decorative panel 4 is installed.

[0033] The iron sheets are located at both ends and the middle of each decorative panel 4 along the first direction. This allows each decorative panel 4 to be fixed using the magnetic attraction of the magnetic fittings 52 at both ends, and also using the magnetic attraction of the magnetic fittings 52 at both ends and the middle. This makes the installation of the decorative panels 4 flexible and adjustable, and avoids hollow spots that may occur in wider decorative panels 4 due to a lack of support in the middle.

[0034] In one exemplary embodiment, the iron sheet is bonded to the decorative panel 4 with an adhesive having a fire resistance temperature greater than 220 degrees Celsius.

[0035] Specifically, the iron sheet is bonded to the decorative panel 4 with an adhesive, so as not to damage the surface of the decorative panel 4 that is away from the inner substrate 2, thus improving the appearance of the decorative panel 4.

[0036] The adhesive has a fire resistance temperature greater than 220 degrees Celsius, which helps to improve the fire resistance of prefabricated walls.

[0037] In one exemplary embodiment, such as Figures 1 to 3 As shown, the vertical keel 1 is configured as multiple 3U vertical keels 1'. The first end 18 and the second end 19 of the 3U vertical keel 1' are respectively provided with a first insertion groove 12 and a second insertion groove 13. All the openings of the first insertion groove 12 and the second insertion groove 13 have the same orientation. The outer sidewalls 121 and 131 of the first insertion groove 12 and the second insertion groove 13 are provided with magnets 51 and mounting plates 53. The inner sidewalls 122 and 132 of the first insertion groove 12 and the second insertion groove 13 extend to the side opposite to the opening orientation. The extended structure forms the abutment parts 123 and 133.

[0038] like Figure 2 As shown, the 3U vertical keel 1' includes an adjacent first vertical keel 1'-1 and a second vertical keel 1'-2. One end of the first inner layer substrate 21 along the first direction is inserted into the first insertion groove 12 of the first vertical keel 1'-1, and the other end of the first inner layer substrate 21 along the first direction abuts against the abutting portion 123 of the second vertical keel 1'-2 located on one side of the first insertion groove 12.

[0039] like Figure 2 As shown, one end of the second inner layer substrate 22 along the first direction is inserted into the second insertion groove 13 of the first vertical keel 1'-1, and the other end of the second inner layer substrate 22 along the first direction abuts against the abutting portion 133 of the second vertical keel 1'-2 located on the side of the second end 19.

[0040] Specifically, the 3U vertical keel 1' has three U-shaped grooves and good elasticity, which helps to improve the sound insulation and vibration reduction performance of the prefabricated wall of this application.

[0041] Specifically, the inner substrate 2 is inserted into and abutted by the insertion slots 11 of the adjacent 3U vertical keel 1' at both ends along the first direction, so that the installation process of the first inner substrate 21 and the second inner substrate 22 is simple and the assembly is convenient and fast.

[0042] like Figure 2 As shown, at one end of the inner substrate 2 along the first direction, opposite to one end of the insertion slot 11, a magnet 51 is provided. The magnet 51 is fixed to the mounting plate 53, and the mounting plate 53 is fixed to the inner substrate 2 by fasteners 54. The magnetic attraction component 52 of the decorative panel 4 can be magnetically connected to the magnets 51 of both the vertical keel 1 and / or the inner substrate 2.

[0043] In one exemplary embodiment, such as Figures 6 to 8As shown, the vertical keel 1 is configured as multiple 5U vertical keels 1”. The first end 18 of each 5U vertical keel 1” is provided with a third insertion groove 14 and a fourth insertion groove 15 with openings facing opposite directions. The second end 19 of each 5U vertical keel 1” is provided with a fifth insertion groove 16 and a sixth insertion groove 17 with openings facing opposite directions. At least one of the outer wall 141 of the third insertion groove 14 and the outer wall 151 of the fourth insertion groove 15 is provided with a magnet 51 and a mounting plate 53. At least one of the outer wall 161 of the fifth insertion groove 16 and the outer wall 171 of the sixth insertion groove 17 is provided with a magnet 51 and a mounting plate 53.

[0044] like Figure 6 and Figure 7 As shown, the 5U vertical keel 1” includes an adjacent third vertical keel 1”-1 and a fourth vertical keel 1”-2. The openings of the third insertion slot 14 and the fifth insertion slot 16 of each 5U vertical keel 1” have the same orientation. The opening of the fourth insertion slot 15 of the third vertical keel 1”-1 is opposite to that of the third insertion slot 14 of the fourth vertical keel 1”-2.

[0045] The first inner layer substrate 21 is inserted into the fourth insertion slot 15 of the third vertical keel 1”-1 and the third insertion slot 14 of the fourth vertical keel 1”-2 at both ends along the first direction. The second inner layer substrate 22 is inserted into the sixth insertion slot 17 of the third vertical keel 1”-1 and the fifth insertion slot 16 of the fourth vertical keel 1”-2 at both ends along the first direction.

[0046] Specifically, the 5U vertical keel 1” has 5 U-shaped grooves and the 5U vertical keel 1” has good elasticity, which is beneficial to improving the sound insulation and vibration reduction performance of the prefabricated wall of this application.

[0047] The inner substrate 2 is connected to the insertion slots 11 opposite to the openings of the adjacent 5U vertical keel 1” at both ends along the first direction. This makes the installation process of the inner substrate 2 simple and the assembly convenient and fast.

[0048] In one exemplary embodiment, such as Figure 1 , Figure 2 , Figure 6 , Figure 7 As shown, the prefabricated wall also includes a fireproof and soundproof component 3, which is installed between adjacent vertical keels 1 and located between the first inner substrate 21 and the second inner substrate 22.

[0049] Specifically, the fireproof and soundproof component 3 can improve the fire resistance and sound insulation performance of the prefabricated wall structure of this application. For example, the fireproof and soundproof component 3 can be made of fireproof and soundproof cotton.

[0050] In one exemplary embodiment, such as Figure 9As shown, the magnetic prefabricated wall of this application also includes a top keel 6 and a bottom keel 7. The cross-sections of the top keel 6 and the bottom keel 7 are both U-shaped, and the top keel 6 and the bottom keel 7 are respectively connected to the two ends of the length direction of the multiple vertical keels 1.

[0051] Specifically, Figure 9 A schematic diagram of the assembled structure of the top keel 6, bottom keel 7, vertical keel 1, and through keel 8 is shown. The cross-sections of both the top keel 6 and bottom keel 7 are U-shaped, perpendicular to the first direction, with the U-shaped openings facing the vertical keel 1. The U-shaped openings of the top keel 6 and bottom keel 7 cover both ends of the length of the multiple vertical keels 1.

[0052] Among them, the top keel 6 is used to fix it to the roof, and the bottom keel 7 is used to fix it to the ground.

[0053] In one exemplary embodiment, such as Figure 9 As shown, the prefabricated wall also includes a through keel 8, which is connected to the middle of multiple vertical keels 1 along the second direction. Both the vertical keels 1 and the through keel 8 are arranged in accordance with the requirements of standards or national standard drawings.

[0054] Specifically, the prefabricated wall is equipped with a through keel 8, which can improve the integrity, structural strength and stability of the prefabricated wall and avoid the problem of multiple vertical keels 1 tilting and shifting.

[0055] In one exemplary embodiment, such as Figure 11 As shown, the prefabricated wall of this application also includes a top corner line 9 and a skirting board 10, which are respectively installed at both ends of the decorative panel 4 along the second direction.

[0056] Specifically, such as Figure 11 As shown, the top corner line 9 is fixed to the inner substrate 2 or the keel 6 by fasteners.

[0057] The purpose of installing the top corner trim 9 is to prevent the decorative panel 4 from tilting away from the inner substrate 2. Simultaneously, the top corner trim 9 serves both decorative and tolerance purposes. If the tops of the decorative panels 4 are not on the same horizontal plane, or if there is a flatness error between the top of the decorative panels 4 and the floor slab, the top corner trim 9 can be used to level and cover the surface, preventing the decorative panels 4 from being misaligned along the upper part of the second direction.

[0058] 10 baseboards can be like Figure 11 The skirting board 10 is installed on the lower part of the decorative panel 4 and connected to the inner substrate 2 or the floor joist 7 by fasteners. The skirting board 10 can also be installed on the side of the decorative panel 4 opposite to the inner substrate 2.

[0059] The function of installing the baseboard 10 is as follows: Since the decorative panel 4 and the vertical keel 1 are magnetically connected, the connection constraint between the decorative panel 4 and the vertical keel 1 along the second direction is relatively small. Installing the baseboard 10 can prevent the decorative panel 4 from sliding downwards along the second direction due to gravity, and the baseboard 10 serves to support the decorative panel 4. At the same time, the decorative panel 4 cannot be soaked in water, and the baseboard 10 prevents the decorative panel 4 from being directly exposed to the ground or soaked by water on the ground.

[0060] In one exemplary embodiment, such as Figure 10 As shown, the inner substrate 2 and the decorative panel 4 are arranged in a series along the first direction, and the gaps 23 at the splicing points of the inner substrate 2 and the gaps 43 at the splicing points of the decorative panels 4 are arranged in a staggered manner.

[0061] Specifically, the joint gaps 23 of the multiple inner substrates 2 and the joint gaps 43 of the multiple decorative panels 4 are staggered, so that the entire wall has no continuous seams, which can improve the sound insulation performance of the wall.

[0062] This application embodiment also provides an installation method for a prefabricated wall, applied to the prefabricated wall described in any of the exemplary embodiments above, including: S1 Install the ground keel 7 and the roof keel 6 to the ground and roof respectively.

[0063] S2 Install vertical keel 1, such as Figure 9 As shown, multiple vertical keels 1 are arranged at intervals along the first direction. The length extension direction of the multiple vertical keels 1 extends along the second direction, and the openings of the insertion slots 11 of the multiple vertical keels 1 face the same direction. The two ends of the multiple vertical keels 1 in the second direction are respectively connected to the ground keel 7 and the top keel 6.

[0064] Specifically, multiple vertical keels 1 can be arranged at intervals of 400 mm or 600 mm along the first direction, according to design requirements. The vertical keels 1 can be multiple 3U vertical keels 1', or multiple 5U vertical keels 1".

[0065] Among them, the two ends of the second direction of the multiple vertical keels 1 are respectively connected to the ground keel 7 and the sky keel 6, and are fixed with keel clamps.

[0066] Optionally, such as Figure 9 Multiple vertical keels 1 are connected by a through keel 8 along the middle of the second direction. The frame of the vertical keels 1 is inspected and accepted to meet the requirements of the standard or national standard drawing.

[0067] S3 mounts the first inner layer substrate 21, such as Figure 2 and Figure 7As shown, each first inner layer substrate 21 is installed at both ends along the first direction to the first end 18 of the adjacent vertical keel 1, and at least one end of the first inner layer substrate 21 in the length direction is inserted into the corresponding insertion slot 11.
