Description

Technical Field

[0001] This invention relates to the field of building structure system technology, and more specifically, to an interior wall unit, an interior wall body, and a building. Background Technology

[0002] Building walls, including interior and exterior walls, not only need to provide structural support, but also need to have good thermal insulation, fire resistance, and sound insulation. Interior walls usually also need to be decorated.

[0003] Since indoor spaces are relatively enclosed spaces where people live and work for extended periods, insulation is a crucial requirement for buildings. Specifically, insulation aims to maintain an indoor temperature higher than the outdoor temperature when temperatures are low, and a lower indoor temperature than the outdoor temperature when temperatures are high. The goal of insulation is to keep the indoor temperature relatively stable, creating comfortable conditions for people's lives and work. Existing building walls have poor insulation performance. For interior walls, increasing wall thickness to improve insulation can reduce usable indoor space. Furthermore, existing building walls generally suffer from poor sound insulation, especially for interior walls, where sound insulation is particularly important.

[0004] The existing building interior walls are built on-site, which is not only inefficient but also results in inconsistent quality. The quality depends on the construction workers, and there are many uncertainties in the construction effect. Moreover, it is difficult to guarantee the flatness of the walls.

[0027] The technical solution of the present invention will be further described in detail below with reference to specific embodiments. It should be understood that the following embodiments are merely illustrative and explanatory of the present invention, and should not be construed as limiting the scope of protection of the present invention. All technologies implemented based on the above content of the present invention are covered within the scope of protection intended by the present invention.

[0028] This embodiment provides an interior wall unit, see reference. Figures 1-3 The system includes: an upper keel 1, a lower keel 2, a first composite wall panel 3, and a second composite wall panel 4. The upper end of the first composite wall panel 3 is connected to the upper keel 1, and the lower end of the first composite wall panel 3 is connected to the lower keel 2. The upper end of the second composite wall panel 4 is connected to the upper keel 1, and the lower end of the second composite wall panel 4 is connected to the lower keel 2. The upper keel 1 and the lower keel 2 are located between the first composite wall panel 3 and the second composite wall panel 4. The first composite wall panel 3 and the second composite wall panel 4 are arranged in parallel and opposite directions, and there is a hollow cavity 5 between the first composite wall panel 3 and the second composite wall panel 4. Any one or more of the following can be arranged in the hollow cavity 5: conduit 6, water pipe 7, heating pipe, and air conditioning pipe. The side of the first composite wall panel 3 has a first connecting structure for connecting adjacent first composite wall panels. The side of the second composite wall panel 4 has a second connecting structure for connecting adjacent second composite wall panels. Here, "adjacent first composite wall panel" refers to the first composite wall panel on other interior wall units, and "adjacent second composite wall panel" refers to the second composite wall panel on other interior wall units.

[0029] In the above embodiments, the upper keel, lower keel, first composite wall panel, and second composite wall panel can all be prefabricated in the factory. During construction, each part can be assembled on-site, which facilitates transportation, improves the construction efficiency of the interior wall, and makes construction quick and convenient. Moreover, the prefabricated first and second composite wall panels have good flatness. The central part of the above-mentioned interior wall unit has a hollow cavity, which can provide good sound insulation and noise reduction, while also improving the thermal insulation performance of the wall. In addition, the hollow cavity can be used to lay conduits or water pipes without affecting the external structure of the interior wall unit, and the pipeline layout is safe and easy to maintain.

[0030] In the above embodiments, the first composite wall panel and the second composite wall panel in the interior wall unit can be exactly the same or different; the first connection structure and the second connection structure can be exactly the same or different.

[0031] For example, both the first composite wall panel 3 and the second composite wall panel 4 include a frame 31, an inner lining panel 32, an outer lining panel 33, and filler 34. The inner lining panel 32 and the outer lining panel 33 are both fixed to the frame 31 and are parallel to each other. The filler 34 fills the gap between the inner lining panel 32 and the outer lining panel 33. The frame 31 is fixed to the upper keel 1 and the lower keel 2. The first connecting structure and the second connecting structure are both set on the frame 31. The frame 31 provides a stable connection between the first composite wall panel 3 and the second composite wall panel 4 and the upper keel 1 and the lower keel 2. Simultaneously, the inner lining panel, the outer lining panel, and the filler between them achieve effects such as heat insulation, fireproofing, moisture resistance, and sound insulation. Both the first composite wall panel and the second composite wall panel can be prefabricated in the factory and installed directly on the construction site.

[0032] In some embodiments, the first connecting structure includes connecting sub-components 35 and connecting female-components 36 located on both sides of the first composite wall panel, and the second connecting structure includes connecting sub-components and connecting female-components located on both sides of the first composite wall panel. During assembly, the connecting sub-components and connecting female-components cooperate with each other between two adjacent first composite wall panels, which improves both assembly efficiency and post-assembly sealing. Similarly, the connecting sub-components 35 and connecting female-components 36 cooperate with each other between two adjacent second composite wall panels, which also improves both assembly efficiency and post-assembly sealing. To further improve sealing, a sealing strip 37 can be provided between adjacent connecting sub-components 35 and connecting female-components 36. The sealing strip 37 improves airtightness and further enhances sound insulation.

[0033] Specifically, see Figure 3 The connecting sub-component 35 is a square tube with a groove, and the connecting female component 36 is a square tube with a raised rib, which fits into the groove. This structural design makes assembly easier, and the connecting sub-component and connecting female component can assist in positioning, thereby improving installation efficiency and quality.

[0034] In some embodiments, the frame is a metal frame, and the inner lining is made of sound-insulating and protective material, such as wood, plastic, metal, metal foil, fiber cloth, or fiber paper. The outer lining is made of ceramic tile, marble, glass, rock slab, calcium silicate board, cement board, gypsum board, fiberboard, wood, plastic, or metal. For example, an interior wall unit is used to separate a bathroom and a living room. The outer lining of the first composite wall panel of the interior wall unit is made of ceramic tile, and the outer lining of the second composite wall panel is made of wood. The first composite wall panel faces the bathroom side, and the second composite wall panel faces the living room side. The first and second composite wall panels can use different outer linings to adapt to different scenarios.

[0035] In some embodiments, the filler is a fire-resistant material, thereby ensuring that the wall has good fire resistance. For example, the fire-resistant material is one or more of foam material, fiber material, and metal honeycomb material; the outer lining is provided with a socket box, switch box, power supply box or network cable port.

[0036] In some embodiments, the thickness of the entire interior wall unit is relatively small, thereby reducing the space occupied in the room. For example, the thickness of the first composite wall panel ranges from 2 to 10 cm, the thickness of the second composite wall panel ranges from 2 to 10 cm, the width of the hollow cavity ranges from 1 to 40 cm, and the overall thickness of the interior wall unit ranges from 8 to 50 cm. For instance, the thickness of both the first and second composite wall panels is 5 cm, and the overall thickness of the interior wall unit ranges from 40 cm.

[0037] In some embodiments, the hollow cavity 5 is filled with glass wool boards and blankets, rock wool boards and blankets, or mineral wool boards and blankets for sound absorption and insulation. By filling with these materials, the sound insulation effect can be further improved.

[0038] In some embodiments, both the upper and lower keels are metal square tubes, and the upper and lower keels are parallel to each other; the first composite wall panel and the second composite wall panel are both connected to the upper keel by bolts, self-tapping screws or welding, and the first composite wall panel and the second composite wall panel are both connected to the lower keel by bolts, self-tapping screws or welding.

[0039] This embodiment also provides an interior wall, comprising a plurality of interior wall units according to any of the above embodiments, wherein the plurality of interior wall units are sealed and spliced ​​together by connectors. Because this interior wall has a hollow cavity, it has a noise reduction and soundproofing effect, and is quick and convenient to construct, with high construction efficiency. It can also conceal pipelines, making it safer and easier to maintain.

[0040] In some embodiments, a sealing strip is provided between the first connecting structures of two adjacent interior wall units, and a sealing strip is provided between the second connecting structures of two adjacent interior wall units; specifically, a sealing strip is provided between the connecting sub-component of one interior wall unit and the connecting female-component of an adjacent interior wall unit; the sealing strip further improves the sealing performance between the two interior wall units.

[0041] The first and second connecting structures both conceal connectors, allowing them to be hidden within the interior wall unit and thus avoiding any impact on the external aesthetics.

[0042] The connectors consist of bolts and nuts that fit the bolts; two adjacent interior wall units are connected and secured by at least two connectors to ensure the stability of the interior wall unit connection.

[0043] This embodiment also provides a building, including the interior walls of any of the above embodiments. The building can be an office building, a residential building, a shop, etc.
