Description

Technical Field

[0001] This utility model relates to the field of building envelope technology, and in particular to a double-layer perforated plate rainproof structure. Background Technology

[0002] In modern architectural design, in pursuit of good natural lighting, open views, and the integration of indoor and outdoor spaces, a large number of architectural spaces have adopted open facade designs. These spaces are usually open to the external environment on one or several sides. While they can achieve excellent views and ventilation, they also face the problem of being directly exposed to wind and rain. Especially in cases of heavy rainfall accompanied by strong winds, a large amount of rainwater can easily drift into the interior, seriously affecting the normal operation of internal activities and causing damage to building decorations, equipment, and facilities.

[0003] To address the aforementioned problems, a common solution in existing technologies is to install rainproof louvers. Rainproof louvers, with their specifically angled and shaped blades, allow air to pass through while blocking rain to a certain extent. This solution can provide basic rain protection under certain conditions.

[0004] However, in practical applications, it has been found that traditional rainproof louvers have many inherent defects and are difficult to meet the needs of high-standard open spaces. Their main drawbacks are as follows:

[0005] 1. Severely obstructs the view and affects natural light: To achieve effective rain protection, rainproof louvers are usually designed with densely packed blades and a large angle, forming a significant visual barrier. This not only severely obstructs the view for indoor users and destroys the openness and transparency that an open space should have, but also significantly reduces the efficiency of natural lighting.

[0006] 2. Impedes natural ventilation: The blade structure of the rainproof louvers creates significant resistance to airflow, substantially reducing the efficiency of indoor and outdoor air circulation. This not only affects the ventilation of the building space, leading to decreased indoor air quality and a stuffy feeling, but more importantly, it poses a serious threat to the building's fire protection and smoke extraction performance.

[0007] In conclusion, existing rainproof louver solutions, due to their significant shortcomings in visual transparency, ventilation, and fire safety, can no longer meet the high requirements of contemporary open-plan architectural spaces for a unified approach to function, safety, and aesthetics. Utility Model Content

[0008] The purpose of this utility model is to provide a double-layer perforated plate rainproof structure that can ensure both visual transparency inside and outside the building and ventilation of the building space while having strong rainproof capabilities.

[0009] To achieve the above objectives, this utility model provides a double-layer perforated plate rainproof structure, which includes:

[0010] A perforated plate assembly includes a first perforated plate and a second perforated plate that are parallel to each other. The first perforated plate has a plurality of spaced first through holes, and the second perforated plate has a plurality of spaced second through holes. The positions of the second through holes are aligned with the positions of the first through holes, and the orthographic projection of the second through holes on the first perforated plate covers the first through holes.

[0011] The perforated plate assembly is connected to a column at each end, and the perforated plate assembly is installed on the building structure through the columns.

[0012] Optionally, there may be multiple perforated plate assemblies, and the ends of two adjacent perforated plate assemblies may be connected by the column.

[0013] Optionally, one end of the first perforated plate is connected to one end of the second perforated plate by a column, and the other end of the first perforated plate is connected to the other end of the second perforated plate by another column, and the distance between the first perforated plate and the second perforated plate is 80-150mm.

[0014] Optionally, both ends of the first perforated plate are provided with a first bend for connection with the column; both ends of the second perforated plate are provided with a second bend for connection with the column.

[0015] Optionally, the second through hole and the first through hole are the same size, the first through hole is evenly distributed on the first perforated plate, and the second through hole is evenly distributed on the second perforated plate.

[0016] Optionally, the perforation rate of the first perforated plate is 40% to 60%, and the perforation rate of the second perforated plate is 40% to 60%.

[0017] Optionally, the diameter of the first through hole is 8-12 mm, and the diameter of the second through hole is 8-12 mm.

[0018] Optionally, the double-layer perforated plate rainproof structure includes a connector, and the column is connected to the building structure through the connector.

[0019] Optionally, the connector includes an adapter and an embedded part, a portion of which is embedded in the building structure, and the column is connected to the adapter and the embedded part.

[0020] Optionally, the building structure includes beams, and the columns are connected to the bottom of the beams.

[0021] As configured above, this utility model provides a double-layer perforated panel rainproof structure, which includes a perforated panel assembly and columns. The perforated panel assembly includes a first perforated panel and a second perforated panel that are parallel to each other. The first perforated panel has a plurality of spaced-apart first through holes, and the second perforated panel has a plurality of spaced-apart second through holes, with the positions of the second through holes aligned with the positions of the first through holes. The orthographic projection of the second through holes onto the first perforated panel covers the first through holes. Each end of the perforated panel assembly is connected to a column, and the perforated panel assembly is mounted on a building structure via the columns.

[0022] This utility model's perforated panel assembly comprises a first perforated panel and a second perforated panel that are parallel to each other, with the first and second through holes aligned. Clear and feasible numerical ranges are provided for the perforation rate, the spacing between the first and second perforated panels, and the diameters of the second and first through holes. This allows the double-layer perforated panel to balance permeability and rain protection. The double-layer perforated panel with aligned holes effectively isolates most rainwater while ensuring good visual permeability between the interior and exterior spaces of the building, guaranteeing the viewing and lighting needs of the interior space. Furthermore, the aligned holes (i.e., the first and second through holes) on the double-layer perforated panel also ensure effective airflow, avoiding interference with the smoke extraction and fire protection performance of open spaces. In summary, this utility model, while possessing strong rain protection capabilities, ensures both visual permeability between the interior and exterior of the building and ventilation of the building space. It can be used in open building spaces with people in use as well as in equipment rooms with ventilation and heat dissipation requirements, making it widely applicable. Attached Figure Description

Figure 2 This is a schematic diagram of the first perforated plate of a double-layer perforated plate rainproof structure according to an embodiment of the present invention. Figure 3 This is a schematic diagram of the second perforated plate in a double-layer perforated plate rainproof structure according to an embodiment of this utility model. Please refer to it. Figure 1 , Figure 2 and Figure 3 This utility model embodiment provides a double-layer perforated plate rainproof structure, including a perforated plate assembly 1 and a column.

[0039] The perforated panel assembly 1 includes a first perforated plate 11 and a second perforated plate 12 that are parallel to each other. The first perforated plate 11 has a plurality of spaced-apart first through holes 111, which are evenly distributed on the first perforated plate 11. The second perforated plate 12 has a plurality of spaced-apart second through holes 121, which are evenly distributed on the second perforated plate 12. The positions of the second through holes 121 and the first through holes 111 are aligned, and the orthographic projection of the second through holes 121 on the first perforated plate 11 covers the first through holes 111 to ensure good visual transparency between the interior and exterior spaces of the building. Preferably, the second through holes 121 and the first through holes 111 are the same size, that is, the orthographic projection of the second through holes 121 on the first perforated plate 11 coincides with the first through holes 111.

[0040] Each end of the perforated plate assembly 1 is connected to a column 3, meaning that each end of the perforated plate assembly 1 is connected to a column 3, and the perforated plate assembly 1 is installed on the building structure via the columns 3. Specifically, one end of the first perforated plate 11 is connected to one end of the second perforated plate 12 via a column 3, and the other end of the first perforated plate 11 is connected to the other end of the second perforated plate 12 via another column 3. Further, the column 3 can be, for example, a square tube. Even further, both ends of the first perforated plate 11 are provided with a first bend 112 for connection to the column 3, and the first bend 112 can be connected to the column 3 via, for example, a first screw 41; both ends of the second perforated plate 12 are provided with a second bend 122 for connection to the column 3, and the second bend 122 can be connected to the column 3 via, for example, a second screw 42. The first perforated plate 11 or the second perforated plate 12 can also be connected to the column 3 via a bracket 5, for example, the first bend 112 is connected to the column 3 via a bracket 5. Figure 1 and Figure 4 As shown, corner code 5 can be made of aluminum alloy.

[0041] Preferably, there are multiple perforated plate assemblies 1, arranged side by side, such as... Figure 5 As shown, the ends of two adjacent perforated panel assemblies 1 are connected by columns 3. In this embodiment, the building structure includes beams 4, and the columns 3 are connected to the bottom of the beams 4, meaning that multiple perforated panel assemblies 1 are arranged side-by-side below the beams 4. Furthermore, the double-layer perforated panel rainproof structure includes connectors, and the columns 3 are connected to the building structure via these connectors. Please refer to... Figure 6 and Figure 7The connector includes an adapter 21 and an embedded part 22. A portion of the embedded part 22 is embedded in the building structure, and the column 3 is connected to the embedded part 22 via the adapter 21. For example, the adapter 21 can be L-shaped, with its two arms connected to the embedded part 22 and the column 3, respectively.

[0042] This utility model can be used in places with higher requirements for lighting, ventilation, and visibility, as an alternative to rainproof louvers. It can be installed on the exterior of a building facade. The first perforated plate 11 and the second perforated plate 12 can be made of metal or other materials that meet specifications and design requirements. For example, the first perforated plate 11 and the second perforated plate 12 can be made of 5mm thick aluminum plates, and both sides of the aluminum plate can be fluorocarbon coated. A certain installation spacing is maintained between the first perforated plate 11 and the second perforated plate 12. The perforation scheme of the first perforated plate 11 and the second perforated plate 12 is consistent, and they are installed with double-layered holes aligned in the orthographic projection direction of the facade.

[0043] Based on extensive research on perforated panels, the inventors observed that when processing information, the human visual system tends to integrate or average the light signals received from adjacent areas. Simultaneously, according to Gestalt psychology principles, the human brain consciously organizes visual elements into meaningful wholes, rather than isolated components. Therefore, under the same perforation rate, perforated panels with different aperture sizes exhibit completely different visual transparency: small-aperture, high-density perforated panels offer superior visual transparency compared to large-aperture, low-density perforated panels. The inventors concluded that the transparency of perforated panels is mainly affected by three factors: 1. Aperture size (affecting both visual transparency and rainproofing ability); 2. Spacing between the two layers of perforated panels (spacing is closely related to aperture alignment); 3. Perforation rate (directly affecting rainproofing ability and transparency). Specifically, the perforation rate of the first perforated panel 11 is 40%–60%, and the perforation rate of the second perforated panel 12 is 40%–60%. The spacing between the first perforated panel 11 and the second perforated panel 12 is 80–150 mm. The diameter of the first through hole 111 is 8-12 mm, and the diameter of the second through hole 121 is 8-12 mm.

[0044] The inventors first used computer software simulations to determine the approximate range of key data such as the spacing between the two perforated panels, the aperture, and the perforation rate for optimal rain protection. Specifically, the inventors designed a simulation program using Rhino-Grasshopper software to simulate scenarios and screen data. Through controlled variable simulation experiments, variables such as rainfall, wind speed, perforation rate, aperture, and panel spacing were controlled individually. With the target value of less than 20% of raindrops passing through the second perforated panel (meaning raindrops first pass through the first perforated panel and then through the second), numerous simulation experiments were conducted, and data that did not meet the building's functional requirements were excluded, resulting in feasible value ranges for the perforated panel spacing, perforation rate, and aperture. Based on the reasonable value ranges of each parameter simulated by the computer, further verification was conducted through experiments, specifically verifying the rainproof effect of different perforation rates and apertures under different rain conditions. The experimental plan is as follows: Figure 8 and Figure 9 , Figure 9 In the figure, i = 5% indicates that the drainage slope of the deep water tank is 5%, which facilitates the drainage of rainwater from the deep water tank into the collection tank. In the experiment, the distance between the first perforated plate 11 and the second perforated plate 12 was 100 mm. The experimental data are shown in Table 1.

[0045]

[0046] Table 1

[0047] The simulation experiments revealed that, under the same rain conditions, changes in the perforation diameter of the perforated plate had a greater impact on rainwater blocking efficiency than changes in the perforation rate. Under the same conditions, smaller perforations significantly improved rain-blocking performance compared to larger perforations. Regarding the visual permeability of the double-layer perforated plate, a higher perforation rate resulted in better permeability than a lower perforation rate, and at the same perforation rate, smaller perforations provided better permeability than larger perforations. The experimental results concluded that a 50% perforation rate and a 10mm hole diameter scheme is the optimal solution for this invention (although the 30% perforation rate and 10mm hole diameter scheme in Table 1 resulted in the least amount of rainwater splashing in, its permeability was lower than the 50% perforation rate and 10mm hole diameter scheme). This scheme effectively blocks most rainwater while maintaining good lighting and visual permeability.

[0048] As configured above, this utility model provides a double-layer perforated panel rainproof structure, which includes a perforated panel assembly 1 and columns 3. The perforated panel assembly 1 includes a first perforated panel 11 and a second perforated panel 12 that are parallel to each other. The first perforated panel 11 has a plurality of spaced-apart first through holes 111, and the second perforated panel 12 has a plurality of spaced-apart second through holes 121. The positions of the second through holes 121 are aligned with the positions of the first through holes 111, and the orthographic projection of the second through holes 121 on the first perforated panel 11 covers the first through holes 111. Each end of the perforated panel assembly 1 is connected to a column 3, and the perforated panel assembly 1 is installed on the building structure through the columns 3.

[0049] The perforated panel assembly 1 of this utility model has a first perforated plate 11 and a second perforated plate 12 that are parallel to each other, and the positions of the first through hole 111 and the second through hole 121 are aligned. It provides clear and feasible numerical ranges for the perforation rate, the distance between the first perforated plate 11 and the second perforated plate 12, the diameter of the second through hole 121 and the diameter of the first through hole 111. This allows the double-layer perforated panel to take into account both permeability and rain protection. The double-layer perforated panel with aligned holes can not only effectively isolate most rainwater, but also ensure good visual permeability between the interior and exterior spaces of the building, ensuring the viewing and lighting needs of the interior space of the building. On the other hand, the aligned holes (i.e. the first through hole 111 and the second through hole 121) on the double-layer perforated panel also ensure the effective flow of air, avoiding affecting the smoke exhaust and other fire protection performance of the open space of the building. In summary, this utility model, while possessing strong rain-blocking capabilities, ensures both visual transparency between the inside and outside of the building and ventilation of the building space. It can be used in open building spaces with people in use, as well as in equipment rooms with ventilation and heat dissipation requirements, making it widely applicable.
