Description

Technical Field

[0001] This invention relates to the field of prefabricated partition wall technology, and in particular to a prefabricated gypsum board partition wall and its installation process. Background Technology

[0002] Currently, gypsum board partitions commonly used in construction projects often employ traditional construction methods, such as on-site assembly with light steel keel, manual panel sealing, and rock wool filling. These methods generally suffer from low assembly efficiency, long construction cycles, and excessive on-site wet work. Traditional partitions often have simple abutments or direct fixation between the top and ceiling, and between the bottom and floor, lacking precise positioning structures. This leads to assembly gaps, making it difficult to meet standards for sound insulation, fire resistance, and airtightness, especially in places with high airtightness requirements such as hospitals and clean spaces. Furthermore, adjacent partition units are often joined planarly without dedicated overlapping structures, resulting in poor overall stability and a tendency to crack and deform. In addition, internal wiring in traditional partitions requires on-site grooving and conduit installation, a cumbersome process that can damage the wall structure. Decorative panels are often single-layered and flat, offering weak sealing and fire resistance, and the lack of uniform support at the bottom of the panels makes them prone to warping and loosening. In summary, existing partitions have significant shortcomings in terms of ease of assembly, connection reliability, sealing performance, integrated wiring, and standardized construction, making them unsuitable for the efficient, high-quality, and high-safety requirements of modern prefabricated buildings. Summary of the Invention

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] A prefabricated gypsum board partition wall includes a ceiling assembly 1, a partition wall assembly 2, and a floor assembly 3; The top surface of the ceiling assembly 1 is fixed to the ceiling by the first mounting member 5, the floor assembly 3 is fixed to the ground by the first mounting member 5, and the partition wall assembly 2 is disposed between the ceiling assembly 1 and the floor assembly 3. The top surface of the partition wall component 2 is interlocked with the bottom surface of the ceiling component 1, and the bottom surface of the partition wall component 2 is plugged into the floor component 3. The outer surfaces of the ceiling assembly 1, partition wall assembly 2 and floor assembly 3 are all covered with decorative components 4; The ceiling assembly 1, partition wall assembly 2, floor assembly 3, and decorative assembly 4 are all fixedly connected by a second mounting component 6.

[0026] like Figure 1-2As shown, this technical solution consists of a ceiling assembly 1, a partition wall assembly 2, a floor joist assembly 3, and a decorative assembly 4. The ceiling assembly 1 is fixed to the ceiling via a first mounting bracket 5, and the floor joist assembly 3 is fixed to the ground via the first mounting bracket 5, forming an upper and lower positioning reference. The partition wall assembly 2 is placed between the two, with its top interlocking with the ceiling assembly 1 for quick alignment, and its bottom interlocking with the floor joist assembly 3 for limited installation, effectively avoiding assembly gaps between the top and bottom, and improving installation efficiency and positioning accuracy. The decorative assembly 4 covers the outer side of each component and is locked together via a second mounting bracket 6, forming an integrated load-bearing structure with the ceiling, partition wall, floor joist, and decorative panel, improving the overall rigidity and stability of the wall, while ensuring airtightness and continuity.

[0027] To further explain, the ceiling assembly 1 includes a ceiling frame 11 and a ceiling body 12, with the ceiling body 12 filling the interior of the ceiling frame 11; The ceiling frame 11 includes an auxiliary keel 111, which is located at the bottom edge of the ceiling frame 11. The partition wall assembly 2 includes a partition wall frame 21 and a partition wall body 22, wherein the partition wall body 22 is filled inside the partition wall frame 21; The partition frame 21 includes a top joist 211, which is located at the top edge of the partition frame 21. The auxiliary keel 111 and the top keel 211 have concave and convex structures on their adjacent sides, and the auxiliary keel 111 and the top keel 211 abut against each other.

[0028] like Figure 2 As shown, the ceiling assembly 1 consists of a ceiling frame 11 and an internally filled ceiling body 12, while the partition wall assembly 2 consists of a partition wall frame 21 and an internally filled partition wall body 22, achieving a layered function of load-bearing frame and sound insulation and fireproofing core material. Figure 9 As shown, the bottom edge of the ceiling frame 11 is equipped with an auxiliary keel 111, such as... Figure 10 As shown, the top edge of the partition frame 21 is provided with a top joist 211, and both have concave and convex contact surfaces, which automatically engage and limit the position during assembly, as shown. Figure 5 As shown, it can quickly locate and reduce on-site calibration, increase the contact area to improve connection strength, and form a stepped sealing surface to block the transmission paths of air, smoke and sound, thereby improving the airtightness of the partition wall.

[0029] To further explain, the partition wall frame 21 also includes a ground joist 212, which is located at the bottom edge of the partition wall frame 21; The ground keel 212 includes a ground keel body 2121, the ground keel body 2121 has a U-shaped cross section and forms a U-shaped slot 2122, and the ground keel body 2121 has ground wing 2123 extending in opposite directions on both sides, and the two ground wing 2123 are arranged perpendicular to the side of the ground keel body 2121. The ground anchor assembly 3 includes a ground anchor keel 31. The ground anchor keel 31 has a concave cross section and forms a U-shaped mounting groove 32. Multiple ground anchor mounting holes are opened at intervals at the bottom of the U-shaped mounting groove 32. The two sides of the ground anchor keel 31 are bent inward to form ground anchor side wings 33. The two ground anchor side wings 33 are set perpendicular to the side of the ground anchor keel 31. The lower sides of the two ground joists 33 are in contact with the ground and are fixed by the ground joist mounting holes through the first mounting member 5. The ground joist 212 is inserted into the outside of the ground joist 31 through the U-shaped slot 2122, and the lower sides of the two ground joists 2123 are in contact with the ground.

[0030] like Figure 11 As shown, the bottom of the partition frame 21 is provided with a ground joist 212. The ground joist body 2121 is U-shaped and forms a U-shaped slot 2122. Ground wing 2123 is provided on both sides for installation close to the ground; as shown Figure 13 As shown, the ground transformer assembly 3 is provided with a ground transformer keel 31, forming a U-shaped mounting groove 32 and having ground transformer mounting holes, and ground transformer side wings 33 on both sides for ground mounting. Figure 6 As shown, the ground keel 212 is sleeved onto the outside of the ground keel through the U-shaped slot 2122 to achieve gapless insertion and positioning at the bottom; at the same time, the first mounting piece 5, which is pre-positioned and installed on the ground, is inserted and fixed to the ground keel 31 through the ground mounting hole to ensure that the ground keel 31 is firmly fixed.

[0031] To further explain, the partition frame 21 also includes side keel 213, which is provided on the two sides of the partition frame 21; The side keel 213 includes an integrally formed side keel body 2131, a first overlapping edge 2132, and a second overlapping edge 2133; The side keel body 2131 has side wings 2134 extending in the same direction on both sides, and the partition wall body 22 is filled between the two side wings 2134. The first overlapping edge 2132 is a folded edge formed by bending one of the side wings 2134 of the side keel body 2131 in the opposite direction. The first overlapping edge 2132 is arranged parallel to the side wing 2134, and the length of the first overlapping edge 2132 is longer than the length of the side wing 2134. The second overlapping edge 2133 is an extension edge formed by extending the other side wing 2134 of the side keel body 2131 in the same direction. The second overlapping edge 2133 is arranged parallel to the side wing 2134, and the length of the extension edge is longer than the length of the side wing 2134. When two adjacent partition wall components 2 are assembled, the two adjacent side keels 213 overlap each other, and the outer side of the second overlapping edge 2133 of one side keel body 2131 overlaps the inner side of the first overlapping edge 2132 of the other side keel body 2131.

[0032] like Figure 1-2 As shown, if the actual length of the partition wall is too long, at least two partition wall components 2 need to be assembled. Figure 8 and 12 As shown, when adjacent partition wall components 2 are assembled, the outer side of the second overlapping edge 2133 on one side and the inner side of the first overlapping edge 2132 on the other side fit together to form a two-way overlapping structure. This structure can improve the positioning accuracy of adjacent unit splicing, enhance the overall resistance to lateral displacement and structural stability, and at the same time form a multi-layered tortuous sealing surface, improving the sound insulation, smoke insulation and airtightness, and avoiding cracking, sound leakage and smoke leakage at the splicing point.

[0033] To further explain, the ceiling frame 11 also includes ceiling joists 112 and ceiling vertical joists 113; The ceiling keel 112 has a U-shaped cross section. The middle plate of the ceiling keel 112 is provided with multiple ceiling mounting holes 114 at intervals. The ceiling keel 112 fits the ceiling and is fixed by the first mounting member 5 passing through the ceiling mounting holes 114. The ceiling vertical rib 113 is disposed between the ceiling keel 112 and the auxiliary keel 111 to form the ceiling frame 11.

[0034] like Figure 1-2 As shown in Figure 4, the ceiling joist 112 is U-shaped and has ceiling mounting holes 114. It is firmly fixed to the ceiling by the first mounting piece 5, providing a top reference. The ceiling vertical joist 113 connects the ceiling joist 112 and the auxiliary joist 111 to form a stable ceiling frame 11 structure, ensuring that the top is evenly stressed and does not deform, providing reliable support for the partition wall assembly 2.

[0035] To further explain, the partition frame 21 also includes partition vertical studs 214, partition horizontal studs 215, and partition bottom studs 216; The partition wall vertical stud 214, partition wall horizontal stud 215 and partition wall bottom stud 216 are all U-shaped in cross section. The partition wall vertical stud 214 is vertically arranged between the top joist 211 and the partition wall bottom stud 216. The bottom joist 212 is arranged on the bottom surface of the partition wall bottom stud 216. The partition wall horizontal stud 215 is horizontally arranged between the partition wall vertical stud 214 and the side joist 213. The partition wall assembly 2 also includes a socket structure 23, which is disposed inside the partition wall frame 21. The socket structure 23 includes a socket frame 231 and a conduit 232. The socket frame 231 is disposed on the partition wall crossbeam 215, and the two ends of the conduit 232 are respectively connected to the socket frame 231. The conduit 232 is used for power supply lines to pass through and synchronously connect the socket frames 231 located at both ends.

[0036] like Figure 2-3 As shown, the partition frame 21 consists of a top joist 211, a bottom joist 212, side joists 213, vertical joists 214, and horizontal joists 215, forming a complete load-bearing skeleton. The vertical joists 214 ensure vertical load-bearing capacity, while the horizontal joists 215 enhance lateral stability and provide installation positions for the socket structure 23. The socket frame 231 is installed on the horizontal joists 215 and is connected to the socket frame 231 via conduit 232, allowing wires to be smoothly connected to the sockets located at both ends of the socket frame 231, realizing integrated wiring within the wall and improving aesthetics, functional integration, and ease of construction.

[0037] To further clarify, both the partition wall body 22 and the ceiling body 12 are made of rock wool.

[0038] Both the partition wall body 22 and the ceiling body 12 are filled with rock wool. By utilizing the non-combustible properties and porous structure of rock wool, the fire resistance, sound insulation, heat insulation and thermal insulation performance of the wall are improved, meeting the requirements of building fire protection codes and high sound insulation.

[0039] To further explain, the decorative component 4 includes a double-layered fireproof board 41; The fireproof board 41 has a socket hole 42 at the position corresponding to the socket frame 231; The bottom surfaces of the double-layer fireproof boards 41 abut against the upper surfaces of the side wings 2123 on both sides of the ground joist body 2121. The double-layer fireproof boards 41 can be staggered on the partition wall assembly 2 so that the edges of the double-layer fireproof boards 41 and the edges of the side joists 213 are stepped.

[0040] like Figure 1 and 6As shown, the bottom surface of the double-layer fireproof board 41 is directly supported on the upper surface of the ground-side wing 2123 of the ground joist 212, forming a continuous and flat bottom support surface, preventing the fireproof board 41 from being suspended, warped, or sinking, and improving the flatness of the panel and the stability of the installation. Figure 2 , 5 As shown in Figure 8, the double-layer fireproof boards 41 are laid in an alternating pattern, creating a stepped staggered structure between the panel edges and the side keel edges 213. This increases the contact area between the panel and the keel, improving fixing reliability and reducing the risk of cracking and detachment. Furthermore, it forms a multi-level, tortuous sealing barrier layer, significantly enhancing the wall's sound insulation, smoke insulation, fire resistance, and airtightness, making it particularly suitable for medical and clean spaces with high airtightness requirements. Figure 1-2 As shown, the fireproof board 41 has a reserved socket hole 42, which can be precisely aligned with the internal socket structure 23, facilitating the quick installation of the socket panel and maintaining the integrity and aesthetics of the wall surface.

[0041] To further explain, the first mounting component 5 includes an expansion bolt rod and a bolt; The second mounting component 6 includes screws.

[0042] The first mounting component 5 uses expansion bolts and bolts to fix the ceiling keel 112 and the ground keel to the building structure, ensuring the strength of the foundation connection; the second mounting component 6 uses screws for internal connections such as frame splicing and panel fixing, which are convenient to operate, reliable to lock, and suitable for factory prefabrication and on-site rapid assembly needs.

[0043] An installation process for a prefabricated gypsum board partition wall as described above includes the following steps: S1. Prefabricate ceiling component 1, partition wall component 2, floor component 3 and decorative component 4 in the factory according to the design and construction drawings; S2. Measure and determine the installation position according to the design requirements, install the first mounting component 5 on the ceiling and the ground, fix the ceiling keel 112 to the ceiling through the first mounting component 5, and fix the floor keel 31 to the ground through the first mounting component 5. S3. Assemble the auxiliary keel 111 and the ceiling vertical keel 113 with the ceiling keel 112 to form the ceiling frame 11; S4. Assemble the ground joists 212, top joists 211, side joists 213, partition wall vertical joists 214 and partition wall horizontal joists 215 to form a partition wall frame 21, and install socket frames 231 and conduits 232 inside the partition wall frame 21. S5. Engage the top joists 211 of the partition wall assembly 2 with the auxiliary joists 111 of the ceiling assembly 1, and connect the bottom joists 212 of the partition wall assembly 2 with the bottom joists. S6. Position the side keel 213 of the adjacent partition wall components 2 by overlapping each other; S7. The wire is passed through conduit 232 from one socket frame 231 and then led out to the other socket frame 231; S8. Fill the interior of the ceiling frame 11 and the partition wall frame 21 with rock wool; S9. Double-layer fireproof board 41 is installed on the outer side of ceiling component 1, partition wall component 2, and floor component 3, and the socket hole 42 on the fireproof board 41 corresponds to the position of socket frame 231. S10. The ceiling assembly 1, partition wall assembly 2, floor assembly 3 and double-layer fireproof board 41 are fixedly connected by the second mounting component 6.

[0044] The installation process corresponding to this invention is based on factory prefabrication. First, the top and bottom reference positions are completed, followed by frame assembly, interlocking, side overlap, integrated wiring, rock wool filling, and panel sealing. Finally, the entire structure is locked and fixed. This process enables modular production and dry on-site operation, significantly improving construction efficiency, reducing human error, and ensuring accurate wall dimensions, structural stability, and reliable sealing. It is suitable for large-scale standardized prefabricated partition wall construction scenarios such as hospitals, offices, and clean spaces.
