Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and in particular to an integrated louvered precast concrete slab. Background Technology

[0002] Prefabricated buildings, due to their advantages such as fast construction speed, controllable quality, and environmental friendliness and energy saving, have gradually become a development trend in substation construction. Substations generate a large amount of heat during operation, and their exterior walls typically require ventilation louvers to meet the equipment's heat dissipation needs. The current mainstream practice is to first install traditional prefabricated wall panels, then excavate openings in the panels, and finally install independent ventilation louvers separately. This "wall panel + post-installed louvers" model has significant drawbacks: First, on-site cutting of the wall panels damages their integrity and insulation layer, complicates the installation process, and prolongs the construction period; second, the joints between the post-installed louvers and the wall panels are prone to becoming weak points in waterproofing, posing a risk of leakage; third, the style and color of the louvers and wall panels are difficult to perfectly match, affecting the overall aesthetics and industrial feel of the building facade. This fails to fully leverage the advantages of prefabricated buildings' "integration" and "modularization," resulting in complex construction processes, limited overall efficiency improvements, and difficulty in ensuring the overall coordination and aesthetics of the facade.

[0003] To address this, we propose an integrated prefabricated exterior wall panel with louvers suitable for substations: highly integrated, functionally compatible, and easy to install; it can reduce on-site construction procedures and wet work, enabling precise prefabrication and efficient construction, thus meeting the urgent needs of prefabricated substation construction. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes an integrated louvered precast concrete slab.

[0005] This utility model proposes an integrated louvered precast concrete slab, comprising a concrete slab, an exterior decorative panel integrally connected to the outer surface of the concrete slab, and an interior decorative panel integrally connected to the inner surface of the concrete slab. Louvers are integrally connected inside the concrete slab, the exterior decorative panel, and the interior decorative panel. The louvers include an outer frame embedded inside the concrete slab, the exterior decorative panel, and the interior decorative panel, and are an integral whole. An inner frame is connected inside the outer frame, and an inclined louver is installed inside the inner frame.

[0006] Furthermore, a waterproof layer is provided between the concrete slab and the exterior trim panel, as well as between the concrete slab and the interior trim panel.

[0007] Furthermore, a stepped groove is provided on the inner side of the outer frame, a window mesh frame is snapped and fixed inside the outer frame, and a window mesh is fixedly connected inside the window mesh frame.

[0008] Furthermore, the back of the window frame abuts against the stepped groove, and the front abuts against the inner frame to fix the window frame.

[0009] Furthermore, the outer frame and the inner frame are connected by a magnetic structure to facilitate the assembly and disassembly of the inner frame.

[0010] Furthermore, the magnetic attraction structure includes a magnetic sheet installed inside the outer frame and a metal sheet installed around the inner frame, wherein the magnetic sheet and the metal sheet are attracted to each other.

[0011] Furthermore, corresponding grooves are provided on the inner circumference of the outer frame and the outer circumference of the inner frame, and the magnetic sheet and metal sheet are embedded and fixed inside the grooves.

[0012] The beneficial effects of this utility model are: 1. The louvers are manufactured as part of the wall panel in a single production run at the factory. During on-site installation, they are simply hoisted and fixed like ordinary wall panels, and the louver ventilation function immediately takes effect. This completely eliminates the tedious processes of on-site cutting, post-installation of louvers, and secondary sealing, greatly improving construction speed. 2. Since there are no seams for later assembly, the risk of leakage due to improper seam treatment is fundamentally eliminated. The integrated structure ensures the continuity and integrity of the airtightness and watertightness of the wall cladding system, making it far more reliable than on-site assembly. 3. The integrated design of louvers and wall panels, with highly unified materials, colors, and styles, gives the substation building a simple, exquisite, and modern industrial aesthetic appearance, significantly enhancing the overall quality.

[0015] Reference Figure 1-5This utility model proposes an integrated louvered precast concrete slab, including a concrete slab 1. An exterior decorative panel 3 is integrally connected to the outer surface of the concrete slab 1. The exterior decorative panel 3 can be made of different textures and colors of decorative materials according to the architectural appearance design requirements, directly forming part of the building's facade, eliminating the need for later exterior wall decoration construction steps. An interior decorative panel 4 is integrally connected to the inner surface of the concrete slab 1. The interior decorative panel 4 can be made of materials that match the interior decoration style, directly serving as the base layer of the interior wall, reducing the workload of secondary interior decoration, and realizing the integrated advantage of the precast panel being "ready to use immediately after installation". To improve the waterproof performance of precast slabs and prevent rainwater or indoor moisture from penetrating and damaging the concrete structure, waterproof layers 2 are provided between concrete slab 1 and exterior decorative panel 3, and between concrete slab 1 and interior decorative panel 4. Waterproof layer 2 is made of waterproof membrane or coating with high sealing performance and aging resistance. It is tightly bonded to concrete slab 1 and decorative panel through an integrated molding process to form a continuous waterproof barrier, effectively blocking the water penetration path and extending the service life of precast slabs. It is especially suitable for building scenarios in rainy or humid areas. The concrete slab 1, the exterior trim panel 3, and the interior trim panel 4 are all connected by a louver 6. The louver 6 includes an outer frame 61, a window mesh frame 62, a window mesh 63, an inner frame 64, and a louver panel 65. The outer frame 61 is embedded inside the concrete slab 1, the exterior trim panel 3, and the interior trim panel 4 and is a whole. It is tightly integrated with the panel structure through a prefabrication process to ensure the stability of the connection between the louver 6 and the prefabricated panel and to avoid gaps or loosening problems that may occur during the later installation of the louver. The inner side of the outer frame 61 is provided with a step groove 611, which is used to position and support the window frame 62. The window frame 62 is fixedly connected to the window mesh 63. The window mesh 63 can be made of stainless steel or high-toughness plastic material, which can prevent insects and dust, while not affecting air circulation. The back of the window frame 62 abuts against the step groove 611, and the front abuts against the inner frame 64, which can realize the stable installation of the window frame 62, and at the same time facilitate the later disassembly and cleaning of the window mesh 63, reducing maintenance costs. The outer frame 61 is internally connected to the inner frame 64. The inner frame 64 is internally fitted with an inclined louvered panel 65. To facilitate the easy assembly and disassembly of the inner frame 64, the outer frame 61 and the inner frame 64 are magnetically fixed together by a magnetic sheet 66 installed on the inner side of the outer frame 61 and a metal sheet 67 installed around the inner frame 64. The magnetic sheet 66 and the metal sheet 67 attract each other, and the magnetic force is used to quickly fix and disassemble the inner frame 64. When it is necessary to clean the louvered panel 65 or repair the internal structure, the inner frame 64 can be separated simply by pulling it outward. The operation is simple and does not require professional tools. During installation, the inner frame 64 is aligned with the outer frame 61, and the magnetic force will automatically guide and complete the fitting and fixing, ensuring installation accuracy. To avoid the magnetic sheet 66 and metal sheet 67 being exposed and affecting the aesthetics, and to prevent damage to the magnetic structure due to collisions during use, corresponding grooves 612 are provided around the inner side of the outer frame 61 and around the outer side of the inner frame 64. The magnetic sheet 66 and metal sheet 67 are embedded and fixed inside the grooves 612, so that the surface of the outer frame 61 and the inner frame 64 remains flat after they are attached. This ensures the stability of the magnetic structure and improves the overall aesthetics of the louver 6.

[0016] In practical construction applications, this integrated louver precast concrete panel can be prefabricated in the factory, and then directly hoisted and assembled after being transported to the construction site. Compared with the traditional construction method of "building walls first and then installing louvers", it significantly shortens the construction cycle, reduces on-site work procedures (such as wall decoration, waterproofing, and louver installation), and lowers labor costs and construction errors. At the same time, the integrated structure avoids gaps between components, improving the overall sealing, insulation, and waterproofing of the building, which is in line with the development trend of modern prefabricated buildings that are efficient, environmentally friendly, and energy-saving.
