Description

Technical Field

[0001] This invention belongs to the field of architectural louver skin technology, and particularly relates to a vertical architectural louver skin system for nighttime landscapes. Background Technology

[0002] As people's aesthetic standards and cultural tastes continue to improve, the nighttime landscape of building facades is receiving increasing attention. However, the development of architectural nighttime lighting in China started relatively late, and research in this field is still weak. Existing methods for architectural facade nighttime lighting are relatively simple, and new lighting demands are constantly emerging, making it difficult to meet the needs of modern society. Currently, most architectural facade nighttime lighting methods cannot effectively integrate lighting with architecture. Adding lighting design to existing building facades has poor effects and may even negatively impact the city's image. Therefore, it is necessary to comprehensively consider architectural facade design and nighttime lighting design, integrating the two to ensure that the lighting truly and completely expresses the architecture while enhancing the city's image.

[0003] Currently, more and more buildings are using architectural louvers as the exterior skin to address issues such as radiation, glare, and energy consumption associated with existing glass curtain walls, as well as to improve aesthetics. However, while a single architectural louver can enhance the daytime facade display effect, the nighttime effect still needs improvement. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a vertical architectural louver skin system for nighttime landscapes. The vertically arranged louvers are set on the building surface and control the natural light and heat entering the building interior according to the sun's position and angle of illumination, so as to achieve shading and light adjustment. At the same time, it can also provide a variety of different and distinctive landscape visual effects at night by rotating the vertical angle. It requires less installation space and has high safety during the rotation process.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A vertical architectural louver skin system for nighttime landscape design includes multiple vertical louver devices. Each vertical louver device includes a frame disposed on the outside of glass. The frame includes a connecting plate extending horizontally. Multiple vertically extending louvers are disposed in the area between the connecting plates. The multiple louvers are arranged sequentially in the same direction and can form a sunshade surface when parallel to the glass. Each louver includes a GRC projection layer, double-layered laminated glass, and an aluminum panel installed in the same frame. The aluminum panel and the double-layered laminated glass are respectively disposed on both sides of the GRC projection layer. An LED strip is also disposed between the double-layered laminated glass and the GRC projection layer. When the louvers are in the sunshade state, the aluminum panel is located on the side of the GRC projection layer away from the glass and parallel to the glass. The GRC projection layers of the multiple vertical louver devices combine to form a nighttime landscape.

[0007] In one embodiment, each of the louvers is provided with a vertically extending rotating shaft at both its upper and lower ends. The rotating shaft is connected to the frame, and one end of the rotating shaft is connected to a drive motor. The drive motor is embedded in the connecting plate, and the drive motor is electrically connected to a controller, which is located inside the glass.

[0008] In one embodiment, a rotating shaft located at one end of the louver is connected to the frame, and a rotating shaft located at the other end of the louver is connected to a drive shaft seat embedded in the connecting plate. The drive shaft seat is connected to the drive motor through a spur gearbox.

[0009] In one embodiment, each of the drive shaft seats is connected to a worm gear box, and multiple worm gear boxes are connected to the spur multi-tooth gear box.

[0010] In one embodiment, the light strip is disposed at the upper and lower ends of the louvers to provide a light source to the GRC projection layer.

[0011] In one embodiment, the GRC projection layer has a hollow structure, and different decorative structures are engraved on multiple GRC projection layers, with the multiple decorative structures forming the nighttime landscape.

[0012] In one embodiment, the controller further includes a sensing device and a control device, the control device being connected to the sensing device and the drive motor, respectively.

[0013] In one embodiment, the connecting plate is a honeycomb aluminum panel cladding that is connected to the exterior wall.

[0014] In one embodiment, the frame is composed of multiple aluminum alloy frames, and the rotation axis is disposed on the aluminum alloy frames.

[0015] In one embodiment, the light strip is an LED linear light source.

[0016] The beneficial effects of this invention are as follows:

[0017] (1) Vertically arranged slats can be fixed to the building surface to control the natural light and heat entering the building according to the position and angle of the sun. This can achieve shading and light adjustment, while also providing a way to enhance the aesthetics of the building facade.

[0018] (2) Compared with fixed architectural louvers, this application can achieve different facade effects by rotating at different angles, thereby enhancing the landscape effect;

[0019] (3) The different materials of the louvers allow for light shading and heat insulation during the day through aluminum panel cladding, while at night the visual effect of the nighttime landscape is enhanced by the leaf surface composed of GRC projection layer, light strip and glass.

Detailed Implementation

[0031] The invention will now be further described with reference to the accompanying drawings.

[0032] The invention provides a vertical architectural louver skin system oriented towards nighttime landscapes, such as... Figures 1 to 3 As shown, it includes multiple vertical louver devices. Each vertical louver device includes a frame set on the outside of the glass 1. The frame includes a connecting plate extending in the horizontal direction. Multiple vertically extending louvers 3 are set in the area between the connecting plates. The multiple louvers 3 are arranged sequentially in the same direction, and the multiple louvers 3 can form a sunshade surface when parallel to the glass 1. Each louver 3 includes a GRC projection layer 302, double-layer laminated glass 306 and aluminum single panel 301 installed in the same frame. The aluminum single panel 301 and double-layer laminated glass 306 are respectively set on both sides of the GRC projection layer 302. A light strip 304 is also set between the double-layer laminated glass 306 and the GRC projection layer 302. When the louvers 3 are in the sunshade state, the aluminum single panel 301 is located on the side of the GRC projection layer 302 away from the glass 1 and is parallel to the glass 1. The GRC projection layer 302 of the multiple vertical louver devices are combined to form a night view.

[0033] It should be noted that multiple vertical louver devices are combined to form a structure like... Figure 1 The landscape shown features vertically rotating louvers 3 that can adjust the indoor light intensity during the day and can be adjusted to different angles at night to create different nighttime landscapes. The light strip 304 illuminates the GRC projection layer 302, creating a continuous and gradual landscape effect. Compared with conventional horizontally rotating louvers 3, it not only requires less installation space but is also safer during rotation. Compared with ordinary nightscape skin, its vertically rotating structure can also bring more and stronger landscape effects.

[0034] Specifically, the GRC projection layer 302 has a hollow structure, and different decorative structures are carved on multiple GRC projection layers 302. Multiple decorative structures form a nighttime landscape, that is, the light strips 304 at the top and bottom of the louvers 3 transmit light through the concave and convex decorative structures to form a continuous and gradual landscape effect.

[0035] In one embodiment, each louver 3 is provided with a vertically extending rotating shaft at both its upper and lower ends. The rotating shaft is connected to the frame, and one end of the rotating shaft is connected to a drive motor 6. The drive motor 6 is embedded in the connecting plate and electrically connected to a controller. The controller is located inside the glass 1. That is, multiple louvers 3 can rotate at different angles in the vertical direction as needed, driven by the drive motor 6, to provide shading or sunlight, achieve the best energy-saving state, and significantly improve the energy-saving and emission-reduction effect of the building. At the same time, the vertical structure also reduces the demand for horizontal space. For example, in an office building, the louver window is installed on the south-facing exterior wall of the office building. The controller drives the louver 3 to rotate to form different angles with the glass 1, thereby adjusting the light intensity. Similarly, at night, the drive motor 6 can drive the louver 3 to rotate to different angles to form different landscape effects.

[0036] Specifically, the controller also includes a sensing device and a control device. The control device is connected to both the sensing device and the drive motor 6. The control modes can be divided into different modes such as manual control, adaptive control, timing control, and scene control.

[0037] For example, the user can manually control any one or more motors to drive the louver 3 to a certain state;

[0038] If adaptive control is implemented, the angle between the louver 3 and the glass 1 can be adjusted according to the indoor light intensity and time to achieve the most comfortable state. A human presence sensor can also be added. For example, during summer working hours, if there are people in the room, the motor will work according to the manual switch or adaptive command. If there are no people in the room, the louver 3 will be set to enter the state of complete sun shading.

[0039] For example, timed control, as needed, can control any one or more motors within a certain time period to drive the louvers 3 to a specified state;

[0040] The drive motor 6 may also include access control, which prevents local control under preset conditions, such as at night, to ensure the overall uniformity of the facade and achieve the target landscape effect.

[0041] By controlling the rotation of the louver 3 at different angles, different light-adjusting states can be achieved. For example, when the sun is shining directly, the light intensity is high, the louver 3 is parallel to the glass 1, and the aluminum single piece is located on the outer side. Figure 6As shown, when the intensity of sunlight decreases, the light-adjusting angle of the louver 3 is controlled according to the wind direction and ventilation needs. When the intensity of sunlight is low, or on cloudy or rainy days, and natural lighting is needed inside the building, the light-adjusting angle of the louver 3 is 90° to increase natural sunlight. When natural lighting is not needed at night, the louver 3 rotates 180° so that its double-layered laminated glass 306 is on the outermost side, forming a rich night view effect on the building facade. That is, the front and back of the louver 3 use different materials to achieve different effects, which can both block light and display a good night view effect.

[0042] In one embodiment, such as Figure 3 , Figure 4 as well as Figure 5 As shown, a sliding bearing 10 is fitted on the rotating shaft at one end of the louver 3 and connected to the frame through a T-shaped seat 8. The rotating shaft at the other end of the louver 3 is connected to a drive shaft seat 5 embedded in the connecting plate. The drive shaft seat 5 is connected to the drive motor 6 through a straight multi-tooth gearbox 11. The drive shaft seat 5 is embedded in the connecting plate for concealment. It is connected to the rotating shaft and the drive motor 6 respectively. Under the action of the drive motor 6, the rotating shaft is driven to rotate, so that the angle between the louver 3 and the glass 1 changes, without affecting the appearance of the building and ensuring that the louver 3 can rotate stably in the vertical direction.

[0043] Furthermore, such as Figure 4 and Figure 5 As shown, each drive shaft seat 5 is connected to a worm gear box 7. Multiple worm gear boxes 7 are connected to a spur gear box 11. The worm gear box 7 has a self-locking system. No matter what position the louver 3 is in, the self-locking property of the worm gear can stabilize the louver 3. The worm gear module is 2 modules, which ensures that the louver 3 will not be damaged under a wind pressure of 0.3kN / m². The worm gear is made of 40cr and has undergone high-temperature heat treatment. It is filled with high-temperature grease for lubrication. The speed ratio is 1:13.5. It takes about 27 seconds to rotate 180°. The minimum accuracy of each movement of the louver 3 is 3 degrees, which ensures that the louver 3 can be adjusted accurately and in multiple modes to meet the adjustment needs of different weather conditions or users.

[0044] In one embodiment, such as Figure 3 As shown, the frame consists of multiple aluminum alloy frames, with the rotating shafts mounted on the aluminum alloy frames. The connecting plates are made of honeycomb aluminum panels that connect to the exterior wall. The frame is formed by combining aluminum alloy frames, and the rotating shafts located on the upper and lower sides of the louver 3 are connected to the aluminum alloy frames. The connecting plates are made of honeycomb aluminum panels, which improves the aesthetics of the exterior wall and, on the other hand, allows for... Figure 7As shown, it is equipped with a drive motor 6, a worm gear box 7, and a drive shaft seat 5. Each louver 3 is connected to a drive shaft seat 5. Under the action of the drive motor 6, multiple louvers 3 are driven to rotate simultaneously through a coupling.
