Abstract
Description
A partition wall using light steel keel connections Technical Field
[0001] This utility model relates to the field of building wall technology, and in particular to a partition wall using light steel keel connection. Background Technology
[0002] Prefabricated partition walls are a building interior partition wall system that uses standardized prefabricated partition wall components for rapid assembly. Their core advantages lie in the ease of construction and reusability brought about by modular design. As an important technological direction in the field of building interior decoration, prefabricated partition walls have been widely used in recent years due to their advantages such as convenient construction and modular production.
[0003] In existing technologies, partition wall bases mostly adopt a fixed-height ground joist structure, such as the prefabricated silent partition wall disclosed in Chinese Patent Publication No. CN118498571A. This type of structure uses expansion bolts to directly anchor the ground joists for initial positioning, adjacent partition wall modules are vertically fixed using horizontal joists, and the top is fixed to the upper floor slab using ceiling joists. However, this type of partition wall still has several drawbacks: First, the joist connection structure of most partition walls relies on on-site cutting and positioning, resulting in insufficient installation accuracy and problems such as misalignment and deviations in wall straightness. Second, the fixing of the wall to the building structure (ground, floor slab) often uses simple bolts or adhesives, which pose risks such as low connection strength and poor seismic performance. Third, the connectors between adjacent wall panels lack versatility, making it difficult to adapt to the modular splicing requirements of different thicknesses or materials, affecting the overall structural stability.
[0004] Furthermore, the pre-installation of pipelines and the construction of decorative surfaces in traditional partition wall systems typically require separate steps, leading to complex procedures and extended construction periods. While some solutions using light steel keel systems attempt to optimize connection methods, limitations such as unreasonable keel interface design and inappropriate fastener selection still hinder the synergy between high-precision factory prefabrication and efficient on-site assembly. How to balance standardized production with on-site adaptability through structural innovation has become a key challenge in enhancing the competitiveness of prefabricated partition wall technology.
[0005] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

[0034] Example 1
[0035] Please refer to Figures 1 to 4. This embodiment discloses a partition wall connected by light steel keel, including multiple wall bodies 10 spliced vertically in sequence, and adjacent wall bodies 10 are connected by H-shaped components 20.
[0036] The bottom wall 10 is connected to the ground 91 via a first connector 30, which includes:
[0037] U-shaped light steel keel 31 anchored to the ground 91;
[0038] The first M-shaped keel 32 is fixed to the bottom wall 10, and the first M-shaped keel 32 and the U-shaped light steel keel 31 are vertically inserted together;
[0039] The first self-tapping screw 33 penetrates and fixes the U-shaped light steel keel 31 and the first M-shaped keel 32 laterally;
[0040] The top wall 10 is connected to the floor slab 92 via a second connector 40, the second connector 40 comprising:
[0041] The first right-angle keel 41 is anchored at the upper end to the floor slab 92;
[0042] The second right-angle keel 42 is snapped together with the first right-angle keel 41;
[0043] The first right-angle keel 41 and the second right-angle keel 42 are respectively fixedly connected to both sides of the top wall 10.
[0044] The partition wall provided in this embodiment, connected by light steel keel, achieves rapid installation through modular design and factory prefabrication. The vertical insertion of the U-shaped light steel keel 31 and the first M-shaped keel 32, combined with the lateral fixing of the first self-tapping screw 33, enables the connection between the bottom wall 10 and the ground 91 to have both guiding positioning and shear resistance, effectively improving installation accuracy and structural stability. The top adopts a snap-fit connection structure of the first right-angle keel 41 and the second right-angle keel 42, which, together with the anchoring of the floor slab 92, forms a flexible support that can adapt to slight deformation of the building structure and ensure the reliability of the top connection. The insertion of the H-shaped component 20 with the adjacent wall 10 simplifies the vertical splicing process, and the standardized components achieve seamless connection of multiple modules, significantly improving construction efficiency.
[0045] Furthermore, the wall 10 in this embodiment includes a fireproof rock wool layer 11, gypsum boards 12 located on both sides of the fireproof rock wool layer 11, and decorative paper 13 covering the outer surface of the gypsum boards 12. The wall 10 forms an integrated fireproof and soundproof structure through the fireproof rock wool layer 11 and the gypsum boards 12 on both sides. The fireproof rock wool layer 11 effectively blocks the spread of fire and noise, while providing space for the pre-embedding of internal pipelines. The double-sided gypsum boards 12 form a flat base layer while ensuring the strength of the wall, and the outer decorative paper 13 achieves a ready-to-use effect without secondary decoration. The three components are prefabricated in the factory to form a complete functional unit, which greatly reduces the amount of work required for surface treatment and fireproof filling during on-site construction, further shortens the construction period, and ensures the consistency of decoration quality.
[0046] Please refer to Figure 2. The first self-tapping screw 33 passes through the plasterboard 12 on one side, and then through the U-shaped light steel keel 31 and the first M-shaped keel 32 to be fixed. The first self-tapping screw 33 adopts a lateral through-type installation path, and passes through the plasterboard 12, the U-shaped light steel keel 31 and the first M-shaped keel 32 in sequence to complete the fastening, realizing the integration of the keel connection and plasterboard fixing process.
[0047] Please refer to Figure 4. Two radially symmetrical second M-shaped keels 50 are also provided between two adjacent walls 10. The upper and lower ends of the H-shaped component 20 are respectively inserted into the two second M-shaped keels 50. The H-shaped component 20 is also fixedly connected to the plasterboard 12 and the second M-shaped keels 50 by second self-tapping screws 61. The two adjacent walls 10 form a double connection system through the radially symmetrical second M-shaped keels 50 and the H-shaped component 20. The upper and lower ends of the H-shaped component 20 are inserted into the second M-shaped keels 50 for precise guidance and positioning. The second self-tapping screws 61 penetrate the plasterboard 12 and simultaneously lock the H-shaped component 20 and the second M-shaped keels 50, improving connection stability. This structure, through the nested insertion design of the keels and connectors, combined with the through-fixing of the second self-tapping screws 61, achieves integrated operation of rapid alignment and rigid anchoring between modules, effectively avoiding misalignment and tilting problems caused by step-by-step installation in traditional processes.
[0048] Please refer to Figures 1 and 2. The U-shaped light steel keel 31 is fixed to the ground 91 by the first expansion bolt 34, and the first right-angle keel 41 is fixed to the floor slab 92 by the second expansion bolt 43. The U-shaped light steel keel 31 forms a shear-resistant anchoring system with the ground 91 through the first expansion bolt 34. Its high-strength alloy expansion sleeve generates radial expansion pressure in the ground hole, ensuring the permanent locking between the keel and the concrete base. The first right-angle keel 41 is connected to the floor slab 92 by the pre-embedded second expansion bolt 43. By adjusting the bolt torque, the assembly gap between the keel and the building structure can be precisely controlled, and verticality fine-tuning and load transfer optimization can be completed simultaneously.
[0049] Please refer to Figure 3. The first right-angle keel 41 is provided with a C-shaped groove 411, and the second right-angle keel 42 is provided with an O-shaped connecting strip 421 that mates with the C-shaped groove 411. The C-shaped groove 411 of the first right-angle keel 41 and the O-shaped connecting strip 421 of the second right-angle keel 42 form a mechanically interlocking snap-fit structure, achieving tool-free rapid engagement through complementary matching of cross-sectional geometry.
[0050] Please refer to Figure 1. The bottom wall 10 is protected and decorated by integrated skirting boards 70 on both sides. The skirting boards 70 are installed at the same time as the plasterboard 12 during the factory prefabrication stage. After on-site assembly, they directly form a continuous and complete bottom interface, which not only prevents damage to the wall edges during daily use, but also avoids the traditional skirting board gluing or nailing process through the hidden snap-fit structure, reducing on-site operation steps and ensuring the integrated visual effect of the decorative surface.
[0051] Example 2
[0052] Please refer to Figure 5. The difference between this embodiment and Embodiment 1 is that the partition wall in this embodiment is further equipped with a wiring assembly 80. The wiring assembly 80 includes a conduit 81 located within the fireproof rock wool layer 11, a junction box 82 connected to the lower end of the conduit 81 and extending out of the plasterboard 12, and a bent conduit 83 connected to the upper end of the conduit 81 and extending out of the second right-angle keel 42. The conduit 81 can be prefabricated in the factory within the fireproof rock wool layer 11. The lower junction box 82 extends out of the plasterboard 12 to form a socket interface, and the upper bent conduit 83 extends out of the second right-angle keel 42 to the top space. During construction, only the cables need to be run to complete the wiring of both high-voltage and low-voltage circuits. This design prefabricates the conduit channel and the wall structure simultaneously, avoiding structural damage to the plasterboard 12 and keel caused by on-site grooving. At the same time, the wrapping of the rock wool layer 11 effectively isolates electromagnetic interference from the wiring. The arc-shaped outlet of the top bent conduit 83 balances wiring efficiency and decorative concealment, achieving a unity of functionality and construction convenience.
[0053] The wall 10 at the top achieves a quick ceiling finish through the integrated design of the ceiling 90. The ceiling 90 is concealed and connected to the second right-angle keel 42 during the factory prefabrication stage, and after on-site assembly, it directly forms a flat and continuous ceiling decoration layer.
