Description

Technical Field

[0001] This utility model belongs to the field of building structure technology, and in particular relates to an internal partition wall structure. Background Technology

[0002] In recent years, with the rapid development of the modern construction industry, various new types of interior partition wall structures have been widely used in industrial and civil buildings. Traditional brick-concrete partition walls and concrete walls, due to their large weight, complex construction processes, and long construction periods, can no longer meet the higher requirements of modern buildings for construction speed, environmental performance, and economic efficiency. Therefore, new types of interior partition walls, with lightweight steel framing as the main body and calcium silicate board or gypsum board as the wall surface material, have become one of the mainstream structural forms in the field of building interior partition walls due to their advantages of being lightweight and high-strength, easy to construct, and relatively low in cost.

[0003] However, existing lightweight steel keel interior partition wall structures still have some significant drawbacks in practical applications. Taking the commonly used lightweight steel keel structure as an example, the stability of the wall connection nodes is generally insufficient, especially at the junctions with different materials such as top steel beams, bottom concrete structures, I-beams, or square steel structures. These junctions are prone to cracking, loosening, or misalignment due to temperature differences, deformation, and micro-vibrations of the main structure. Furthermore, the treatment of corner joints, pipeline installation areas, and wall panel splicing gaps is also inadequate, generally resulting in poor structural stability, insufficient sound insulation and fire resistance, and difficulties in later maintenance.

[0004] While existing literature and technical solutions have proposed some improvements—for example, some patented technologies suggest using corbel structures at the joints of the keel or special fire-resistant sealant layers for panel seams, while others propose using galvanized steel plates with square tube structures and rock wool cores to enhance the fire resistance and thermal insulation of the wall—these solutions are typically structurally complex, difficult to construct, and costly. Furthermore, they lack overall stability at the joints and sufficient room for future adjustments, failing to completely resolve the contradiction between the overall structural stability, practicality, and economy of the partition wall. Therefore, providing a new type of interior partition wall structure that is easy to construct, has stable joints, superior overall performance, and is convenient for future maintenance is a crucial technical problem that urgently needs to be solved. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide an internal partition wall structure.

[0006] An interior partition wall structure, comprising:

[0007] Connectors are pre-installed on the top and bottom of the internal partition wall installation location on the I-beams, square steel, or concrete components for fixed connection with the vertical keel.

[0008] The vertical keel is fastened to the connector at its upper and lower ends, and multiple vertical keels are arranged along the length of the inner partition wall.

[0009] A wall panel is installed on the outside of the vertical keel and fixedly connected to the vertical keel to form a wall surface.

[0010] Furthermore, the internal partition wall structure also includes reinforcing keels, which are disposed between adjacent vertical keels and are fastened to the vertical keels to enhance the overall rigidity of the internal partition wall structure.

[0011] Furthermore, the cavity formed by the wall panel, the vertical keel, and / or the reinforcing keel is filled with a filler material, which is used to improve the thermal insulation, sound absorption, and fire resistance of the internal partition wall structure.

[0012] Furthermore, the cavity is also provided with a space for laying pipelines, for concealed installation of electrical conduits, water pipes or network cables; the internal partition wall structure is reserved with inspection ports or openings to facilitate the installation and maintenance of pipelines in the future.

[0013] Furthermore, the internal partition wall structure also includes a corner connection assembly, the corner connection assembly comprising:

[0014] The corner keel overlaps with the ends of the two adjacent vertical keels;

[0015] The corner reinforcement is used to fix the corner keel to the adjacent vertical keel by screws or welding to form a stable support at the corner.

[0016] Furthermore, the internal partition wall structure also includes reinforcing members, which are rigidly connected to the side of the I-beam or square steel and fixedly connected to the vertical keel or the reinforcing keel, in order to enhance the connection strength between the internal partition wall structure and the main steel component.

[0017] Furthermore, the wall panel is selected from gypsum board, calcium silicate board or metal composite board; a decorative panel is added to the outside of the wall panel by a flexible connection, and a gap is reserved between the decorative panel and the wall panel.

[0018] Furthermore, the bottom of the internal partition wall structure is provided with a kickboard, which is fixedly connected to the wall panel. Its upper part is snap-fitted to the decorative panel, and its lower part abuts against the ground to prevent moisture or water from the bottom surface from invading upwards.

[0019] Furthermore, the connector is an adjustable structure, with an adjustment allowance reserved at its mating or connection with the vertical keel, so that the vertical keel has height or position adjustment space during installation or later fine-tuning, to accommodate construction errors of the main steel structure or floor height.

[0020] Furthermore, the connector is provided with an elastic pad at the part that abuts against the I-beam, square steel or concrete to buffer the impact of beam or floor structure vibration and thermal expansion and contraction on the inner partition wall structure.

[0021] The beneficial effects of this utility model are:

[0022] This utility model provides an internal partition wall structure that uses pre-installed connectors at the top and bottom to form a reliable fixed connection with I-beams, square steel, or concrete components. This allows multiple vertical joists to be stably installed in predetermined positions and form continuous support, effectively improving the overall rigidity and stability of the internal partition wall structure. Simultaneously, wall panels are installed on the outside of the vertical joists, further enhancing the integrity, sound insulation, and fire resistance of the wall. This solves problems such as easy cracking, unstable connections, and insufficient strength of load-bearing nodes in existing partition walls, ensuring the long-term reliability of the partition wall structure. Furthermore, this structure, through a simple component assembly method, ensures both ease of construction and convenient later use and maintenance, significantly reducing construction and time costs. It possesses excellent economic and social benefits and is suitable for large-scale application in the construction field. Attached Figure Description

[0031] This embodiment provides an internal partition wall structure 1, including:

[0032] Connector 11 is pre-installed on the top and bottom of the I-beam 21, square steel 20 or concrete component at the installation position of the inner partition wall, for fixed connection with the vertical keel 12.

[0033] Vertical keel 12, the upper and lower ends of which are fastened to connector 11 respectively, and multiple vertical keels 12 are arranged along the length of the inner partition wall;

[0034] The wall panel 13 is installed on the outside of the vertical keel 12 and is fixedly connected to the vertical keel 12 to form a wall surface.

[0035] like Figure 1 , 2 As shown in Figure 3, connectors 11 are installed on the top and bottom of the I-beams 21, square steel 20, or concrete components at the installation location of the inner partition wall structure 1. The top connector 11 preferably uses a U-shaped guide rail or angle steel fastener, reliably fixed to the lower surface of the top steel beam, I-beam, or concrete by welding or bolts. A shock-absorbing foam strip is provided between the connector 11 and the top to reduce vibration and impact. The bottom connector 11 also uses a U-shaped guide rail or angle steel support, fixed to the ground square steel or concrete base by expansion bolts or welded embedded parts to ensure a firm connection between the partition wall structure and the building foundation.

[0036] The vertical keel 12 uses cold-formed thin-walled steel keel, such as conventional C-type keel. The upper and lower ends of the keel mate with the top and bottom connectors 11, respectively, and are securely fastened with self-tapping screws or rivets. According to construction standards and design requirements, the vertical keel 12 is arranged regularly along the length of the inner partition wall at standard intervals of 500mm to 600mm. The wall panel 13 can be made of gypsum board or fiber-reinforced silicate board, with a thickness of approximately 10mm, and is securely installed on the outside of the vertical keel 12 with self-tapping screws, forming a smooth and structurally stable wall surface.

[0037] In some embodiments, the internal partition wall structure 1 further includes a reinforcing keel 14 disposed between adjacent vertical keels 12 and fastened to the vertical keels 12 to enhance the overall rigidity of the internal partition wall structure 1.

[0038] like Figure 1 As shown, the internal partition wall structure 1 is further equipped with reinforcing joists 14. The reinforcing joists 14 are preferably made of galvanized square tubing, C-shaped steel, or channel steel, and are installed at intervals between adjacent vertical joists 12. The reinforcing joists 14 are tightly connected to the vertical joists 12 via angle brackets, self-tapping screws, or riveting fittings to effectively enhance the overall lateral stiffness of the partition wall structure. The specific number and height of the reinforcing joists 14 can be flexibly adjusted according to the actual wall height and load-bearing requirements.

[0039] In some embodiments, the cavity formed by the wall panel 13, the vertical keel 12 and / or the reinforcing keel 14 is filled with a filler 15, which is used to improve the thermal insulation, sound absorption and fire resistance of the internal partition wall structure 1.

[0040] like Figure 1 , 2 As shown in Figure 3, the cavity formed between the wall panel 13, the vertical keel 12, and the reinforcing keel 14 is filled with a filler 15. The filler 15 is preferably made of fireproof rock wool, glass wool, or other thermal insulation materials, with a density range of 80-120 kg / m³. 3 The thickness is generally 50-100mm. The use of filler 15 effectively improves the thermal insulation, sound absorption and fire resistance of the internal partition wall structure 1, and enhances the overall safety and comfort.

[0041] In some embodiments, the cavity is also provided with a pipeline laying space for concealed installation of electrical conduits, water pipes or network cables; an inspection port or opening is reserved on the inner partition wall structure 1 to facilitate the installation and maintenance of pipelines in the future.

[0042] The cavity also includes space for concealed installation of electrical conduits, water pipes, and network cables. Depending on project requirements, PVC electrical conduits or galvanized steel conduits can be laid within this space. The wall panel 13 has access panels or pre-drilled openings at corresponding locations for future maintenance and repair of the wiring.

[0043] In some embodiments, the internal partition wall structure 1 further includes a corner connection component 16, the corner connection component 16 comprising:

[0044] The corner keel 161 overlaps with the ends of the two adjacent vertical keels 12;

[0045] The corner reinforcement 162 is used to fix the corner keel 161 to the adjacent vertical keel 12 by screws or welding to form a stable support at the corner.

[0046] like Figure 4 As shown, the corner connection assembly 16 includes a corner keel 161 and a corner reinforcement 162. The corner keel 161 adopts a C-shaped or special angle steel structure, and its end is connected to two adjacent vertical keels 12 by overlapping. The corner reinforcement 162 is used to firmly fix the corner keel 161 to the vertical keel 12 by screws or welding, forming a reliable corner support structure to prevent the partition wall structure from cracking or deforming due to temperature difference or external force.

[0047] In some embodiments, the internal partition wall structure 1 further includes a reinforcing member 17, which is rigidly connected to the side of the I-beam 21 or square steel 20 and fixedly connected to the vertical keel 12 or reinforcing keel 14 to enhance the connection strength between the internal partition wall structure 1 and the main steel component.

[0048] like Figure 5 , 6 As shown, the reinforcing member 17 is preferably made of galvanized angle steel or reinforced steel plate, with one end rigidly connected to the side of the main I-beam 21 or square steel 20, and the other end connected to the vertical keel 12 or reinforced keel 14 by bolts or self-tapping screws, which significantly improves the structural rigidity and durability of the partition wall node. In addition, the surface of the main steel structure is coated with fire-retardant paint 22, and the gaps where the wall panel 13 and decorative panel 18 meet the fire-retardant paint 22 are filled with fire-retardant sealant 23 to enhance fire resistance.

[0049] In some embodiments, the wall panel 13 is selected from gypsum board, calcium silicate board or metal composite board; a decorative panel 18 is added to the outside of the wall panel 13 by a flexible connection, and a gap is reserved between the decorative panel 18 and the wall panel 13.

[0050] like Figure 1 , 2 As shown in Figure 3, a decorative panel 18 with flexible connection is provided on the outer side of the wall panel 13. The wall panel 13 can be made of gypsum board, fiber reinforced silicate board or metal composite board. A gap of 10-15mm is provided between the decorative panel 18 and the wall panel 13 to absorb the thermal expansion and contraction of the material due to temperature changes, avoid cracking, and further improve the visual effect of the interior partition wall.

[0051] In some embodiments, the bottom of the internal partition wall structure 1 is provided with a kick foot 19, which is fixedly connected to the wall panel 13. Its upper part is snap-fitted to the decorative panel 18, and its lower part abuts against the ground to prevent moisture or water from the bottom surface from invading upwards.

[0052] like Figure 3As shown, the bottom of the internal partition wall structure 1 is equipped with a skirting board 19. The skirting board 19 is preferably made of moisture-proof aluminum alloy or PVC material. The lower part is equipped with a rubber or moisture-proof pad to seal the ground. The upper part is firmly connected to the decorative panel 18 with a snap-on structure. The inner side is fixed to the wall panel 13 by adhesive or self-tapping screws, which effectively prevents moisture or water from penetrating into the wall and extends the service life of the partition wall structure. The gap between the bottom of the wall panel 13 and the ground is filled with fireproof sealant 23 to enhance fire resistance.

[0053] In some embodiments, the connector 11 is an adjustable structure with an adjustment allowance reserved at its mating or connection with the vertical keel 12, so that the vertical keel 12 has height or position adjustment space during installation or later fine-tuning, to accommodate construction errors of the main steel structure or floor height.

[0054] The connector 11 adopts an adjustable structure, specifically, the top or bottom connecting guide rail or angle steel fixing part has a reserved elongated hole or sliding groove hole, so that the installation position of the vertical keel 12 can be finely adjusted in the height or horizontal direction, so as to adapt to the adjustment needs caused by the error of the main structure size during construction and increase the flexibility of installation.

[0055] In some embodiments, the connector 11 is provided with an elastic pad at the part that abuts against the I-beam 21, the square steel 20 or the concrete, for buffering the impact of beam or floor structure vibration and thermal expansion and contraction on the inner partition wall structure 1.

[0056] The connector 11 is fitted with rubber pads or foamed polyethylene shock-absorbing pads with a thickness of 5-10mm at the parts that come into contact with the I-beam 21, square steel 20 or concrete. This effectively reduces the impact of vibration and temperature difference deformation transmitted from the main structure on the internal partition wall structure 1, prevents cracks or detachment of the wall panels, and significantly improves the overall performance and durability.

[0057] For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations, but obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this invention.
