Description

Technical Field

[0001] This utility model relates to the field of glass curtain wall technology, and in particular to an integrated structural device that can switch between outdoor sunshade, ventilation and natural smoke exhaust modes. Background Technology

[0002] Currently, traditional large public buildings typically use opaque metal roofs, with natural lighting usually achieved through side windows or curtain walls. This design for large public buildings has the following shortcomings:

[0003] Firstly, due to insufficient natural lighting area, the lighting effect is poor. Therefore, a large amount of artificial lighting is needed inside the building, which leads to high energy consumption.

[0004] Secondly, when curtain wall lighting is installed, the split shading film is placed on the inside of the curtain wall. When natural lighting is used, outdoor heat radiation cannot be blocked by the split shading film. Therefore, a large amount of central air conditioning is needed inside the building to regulate the room temperature, which leads to high energy consumption. Utility Model Content

[0005] To address the aforementioned issues, this invention provides an integrated structural device with lower energy consumption and switchable outdoor sunshade, ventilation, and natural smoke exhaust modes.

[0006] The technical solution of this utility model is: an integrated structural device that can switch between outdoor sunshade, ventilation and natural smoke exhaust modes, including a window frame, an electric smoke exhaust window, a sunshade film window, a first actuator and a second actuator. An electric smoke exhaust window that can be opened to the outside and is suspended downwards is installed in the window frame. A sunshade film window that can be opened to the outside is installed at the edge of the window frame on the outdoor side, so that the electric smoke exhaust window is located on the side of the sunshade film window closer to the window frame. The first actuator is arranged between the window frame and the electric smoke exhaust window, and the second actuator is arranged between the window frame and the sunshade film window.

[0007] The working principle of the above technical solution is as follows:

[0008] By integrating window frames, motorized smoke exhaust windows, sunshade film windows, and the first and second actuators, the design achieves an integrated structure that saves the area required for separately constructed ventilation and natural smoke exhaust windows. This maximizes the shading area, takes into account the building's natural lighting capacity, and reduces the need for extensive artificial lighting, thereby lowering energy consumption. Furthermore, the outdoor shading design reduces the use of central air conditioning and fresh air systems to regulate indoor temperature, effectively reducing daily energy consumption. Additionally, the simultaneous opening of the motorized smoke exhaust windows and sunshade film windows also meets the needs for ventilation and natural smoke exhaust for indoor fire protection.

[0009] When the fire alarm control box is connected to the first and second actuators, it is connected to the fire alarm system (FAS) via a fire signal line, enabling remote control of the opening and closing of electric smoke exhaust windows and sunshade windows, thus gaining an advantage in fire rescue operations.

[0010] In a further technical solution, the window frame mainly consists of two vertically arranged curtain wall mullions and two horizontally arranged curtain wall beams. One end of one curtain wall mullion is fixedly connected to one end of one curtain wall beam, and the other end of one curtain wall mullion is fixedly connected to one end of the other curtain wall beam. Similarly, one end of another curtain wall mullion is fixedly connected to the other end of one curtain wall beam, and the other end of another curtain wall mullion is fixedly connected to the other end of the other curtain wall beam. By constructing the window frame using curtain wall mullions and beams, and in conjunction with the overlapping design of electric smoke exhaust windows and sunshade film windows, the sunshade area is maximized, maximizing the building's natural lighting capacity and reducing the need for extensive artificial lighting inside the building, thereby achieving the goal of reducing energy consumption.

[0011] In a further technical solution, the electric smoke exhaust window mainly consists of a smoke exhaust window body and hinges. The smoke exhaust window body is installed on the indoor side of the window frame, and the lower hinged side of the smoke exhaust window body is hinged to the curtain wall beam at the lower end of the window frame via hinges. The first actuator is a chain-type electric window opener used to drive the smoke exhaust window body to rotate. Through the coordinated design of the smoke exhaust window body, hinges (e.g., stainless steel hinges), the first actuator, and the curtain wall beam, the overall structure is more rhythmic, avoiding the need for separate window frame installation and saving on installation material costs.

[0012] In a further technical solution, the maximum opening angle of the smoke exhaust window to the outside is 65° to 75°. Preferably, the maximum opening angle of the smoke exhaust window to the outside is 70°. This design, with a maximum opening angle of 65° to 75°, makes ventilation and smoke extraction smoother.

[0013] In a further technical solution, the sunshade window mainly consists of a sunshade window body and a pivot. The upper and lower ends of the hinged side of the sunshade window body are respectively hinged to the curtain wall beams on the upper and lower hinged sides of the window frame via a pivot. The second actuator is an electric swing door actuator used to drive the sunshade window body to rotate. Through the coordinated design of the sunshade window body, pivot, and curtain wall beams, the overall structure is more rhythmic, avoiding the need for a separate window frame and saving on installation material costs.

[0014] In a further technical solution, the sunshade window frame mainly consists of an aluminum alloy frame and a sunshade film. The sunshade film is made of a sunshade and light-transmitting film material. The sunshade film is connected to the aluminum alloy frame by a tensioned and fixed connection or by a detachable connection. The upper and lower ends of the hinged side of the aluminum alloy frame are respectively hinged to the curtain wall beams on the upper and lower hinged sides of the window frame via a pivot. On the one hand, the design of the aluminum alloy frame and the sunshade film prevents outdoor heat radiation from entering the room during natural lighting, thereby reducing the use of central air conditioning and fresh air systems to regulate indoor temperature and effectively reducing the daily operating energy consumption of central air conditioning and fresh air systems. On the other hand, the tensioned and fixed connection of the sunshade film makes installation simpler and more operable; or, the detachable connection of the sunshade film to the aluminum alloy frame facilitates subsequent maintenance and replacement of the sunshade film.

[0015] In a further technical solution, an outdoor curtain box is installed at the top of the window frame on the outdoor side, and the electric swing door actuator is concealed within this outdoor curtain box. Alternatively, if the electric swing door actuator is also installed at the bottom of the window frame on the outdoor side, a structure similar to an outdoor curtain box can be designed to conceal the electric swing door actuator at the bottom of the window frame. This combined design of installing an outdoor curtain box and concealing the electric swing door actuator within it protects the electric swing door actuator and increases its service life.

[0016] The beneficial effects of this utility model are:

[0017] 1. Through the coordinated design of window frames, motorized smoke exhaust windows, sunshade film windows, first actuators, and second actuators, on the one hand, an integrated structure of window frames, motorized smoke exhaust windows, sunshade film windows, first actuators, and second actuators is achieved, saving the area of ​​separately constructed ventilation and natural smoke exhaust windows, maximizing the sunshade area, maximizing the building's natural lighting capacity, reducing the use of artificial lighting inside the building, and thus achieving the goal of reducing energy consumption; on the other hand, the adoption of an outdoor sunshade structure design reduces the use of central air conditioning and fresh air systems to regulate indoor temperature, effectively reducing the daily operation energy consumption of central air conditioning and fresh air systems. In addition, when the motorized smoke exhaust windows and sunshade film windows are opened simultaneously, the needs of ventilation and indoor fire-fighting natural smoke exhaust can also be met.

[0018] When the fire alarm control box is connected to the first and second actuators, it is connected to the fire alarm system (FAS) via a fire signal line, enabling remote control of the opening and closing of electric smoke exhaust windows and sunshade windows, thus gaining an advantage in fire rescue operations.

[0019] 2. The window frame is constructed by curtain wall columns and curtain wall beams, and the overlapping design of electric smoke exhaust windows and sunshade film windows further maximizes the sunshade area, takes into account the natural lighting capacity of the building to the greatest extent, and reduces the use of artificial lighting in the building, thereby achieving the goal of reducing energy consumption.

[0020] 3. The coordinated design of the smoke exhaust window, hinges (e.g., stainless steel hinges), first actuator, and curtain wall beams makes the overall structure more rhythmic, avoids the need for separate window frames, and saves on installation material costs.

[0021] 4. The maximum opening angle of the smoke exhaust window to the outside is 65° to 75°, which makes ventilation and smoke exhaust smoother.

[0022] 5. The coordinated design of the sunshade window frame, pivot, and curtain wall beams makes the overall structure more rhythmic, avoids the need for separate window frames, and saves on installation material costs.

[0023] 6. In this utility model, on the one hand, the design of the aluminum alloy frame and the sunshade film prevents outdoor heat radiation from entering the room during natural lighting, thereby reducing the use of central air conditioning and fresh air systems to regulate indoor temperature and effectively reducing the daily operating energy consumption of central air conditioning and fresh air systems; on the other hand, the sunshade film is installed more simply and is more operable by being connected by tension; or, the sunshade film is connected to the aluminum alloy frame in a detachable manner, which facilitates the subsequent maintenance and replacement of the sunshade film.

[0024] 7. By installing an outdoor curtain box and concealing the electric swing door drive within the outdoor curtain box, the electric swing door drive is protected, increasing its service life.

[0025] 8. When connected to the station's BAS system, the second drive can be controlled in real time based on environmental data such as temperature and solar irradiance, thereby controlling the angle of the outdoor shading film window to achieve the shading function, effectively blocking ultraviolet rays and direct sunlight, and preventing the "greenhouse effect".

Detailed Implementation

[0035] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0036] Example 1:

[0037] like Figure 1-7 As shown, an integrated structural device capable of switching outdoor sunshade, ventilation, and natural smoke exhaust modes includes a window frame, an electric smoke exhaust window, a sunshade film window, a first actuator, and a second actuator. An electric smoke exhaust window that can be opened to the outside and is suspended downwards is installed inside the window frame. A sunshade film window that can be opened outwards is installed at the edge of the window frame on the outdoor side, such that the electric smoke exhaust window is located on the side of the sunshade film window closer to the window frame. The first actuator is disposed between the window frame and the electric smoke exhaust window, and the second actuator is disposed between the window frame and the sunshade film window.

[0038] The working principle of the above technical solution is as follows:

[0039] By integrating window frames, motorized smoke exhaust windows, sunshade film windows, and the first and second actuators, the design achieves an integrated structure that saves the area required for separately constructed ventilation and natural smoke exhaust windows. This maximizes the shading area, takes into account the building's natural lighting capacity, and reduces the need for extensive artificial lighting, thereby lowering energy consumption. Furthermore, the outdoor shading design reduces the use of central air conditioning and fresh air systems to regulate indoor temperature, effectively reducing daily energy consumption. Additionally, the simultaneous opening of the motorized smoke exhaust windows and sunshade film windows also meets the needs for ventilation and natural smoke exhaust for indoor fire protection.

[0040] When the fire alarm control box is connected to the first and second actuators, it is connected to the fire alarm system (FAS) via a fire signal line, enabling remote control of the opening and closing of electric smoke exhaust windows and sunshade windows, thus gaining an advantage in fire rescue operations.

[0041] In another embodiment, the window frame mainly consists of two vertically arranged curtain wall columns 1 and two horizontally arranged curtain wall beams 2. One end of one curtain wall column 1 is fixedly connected to one end of one curtain wall beam 2, and the other end of one curtain wall column 1 is fixedly connected to one end of the other curtain wall beam 2. Similarly, one end of the other curtain wall column 1 is fixedly connected to the other end of one curtain wall beam 2, and the other end of the other curtain wall column 1 is fixedly connected to the other end of the other curtain wall beam 2. By constructing the window frame using the curtain wall columns 1 and curtain wall beams 2, and in conjunction with the overlapping design of electric smoke exhaust windows and sunshade film windows, the sunshade area is maximized, maximizing the building's natural lighting capacity and reducing the need for extensive artificial lighting inside the building, thereby achieving the goal of reducing energy consumption.

[0042] In another embodiment, the electric smoke exhaust window mainly consists of a smoke exhaust window body 4 and hinges. The smoke exhaust window body 4 is installed on the indoor side of the window frame, and the lower hinged side of the smoke exhaust window body 4 is hinged to the curtain wall beam 2 at the lower end of the window frame via hinges. The first actuator is a chain-type electric window opener used to drive the smoke exhaust window body 4 to rotate. Through the coordinated design of the smoke exhaust window body 4, hinges (e.g., stainless steel hinges 5), the first actuator, and the curtain wall beam 2, the overall structure is more rhythmic, avoiding the need for separate window frames and saving on installation material costs.

[0043] The chain-type electric window opener is a mature existing technology. It only needs to be able to open and close the smoke exhaust window 4 without interfering with other structures in this embodiment. Alternatively, the following structure can be used: the chain-type electric window opener mainly consists of a rear end bracket 7, a window opener housing, a first drive motor, a window opener chain 8, and a front end bracket 9. One end of the rear end bracket 7 is fixedly connected to the window frame, and the other end is fixedly connected to the window opener housing. A chain cavity is provided inside the window opener housing. The window opener chain 8 and a first drive motor for driving the window opener chain 8 to extend or retract from the chain cavity are installed inside the chain cavity. The window opener chain 8 extends out of the chain cavity, and the front end bracket 9 is installed on the outer side of the end of the window opener chain 8 away from the chain cavity. The front end bracket 9 is fixedly connected to the sash frame of the smoke exhaust window 4. When the first drive motor is driven to extend the window opener chain 8 from the chain cavity, the smoke exhaust window 4 moves from closed to open; when the first drive motor is driven to retract the window opener chain 8 from the chain cavity, the smoke exhaust window 4 moves from open to closed.

[0044] To enhance the sealing between the smoke exhaust window 4 and the window frame, the hinge between the smoke exhaust window 4 and the window frame is located on the outer side of the window frame. Specifically, a first hinge plate can be connected to the bottom surface of the smoke exhaust window 4 using M5x35 stainless steel pan head screws 6. The hinge position of the first hinge plate extends outward from the side of the smoke exhaust window 4 closest to the outside. A second hinge plate, matching the first hinge plate, can be connected to the inner bottom surface of the window frame using M5x35 stainless steel pan head screws 6. The hinge position of the second hinge plate extends outward from the side of the window frame closest to the outside. The hinge positions of the first and second hinge plates are hinged together using stainless steel hinges. To further enhance the sealing between the smoke exhaust window 4 and the window frame, a stepped fit is formed between the smoke exhaust window 4 and the window frame, and a sealing strip can also be installed on the inner wall of the window frame.

[0045] In another embodiment, the maximum opening angle of the smoke exhaust window 4 to the outside is 65° to 75°. Preferably, the maximum opening angle of the smoke exhaust window 4 to the outside is 70°. This design, with a maximum opening angle of 65° to 75°, makes ventilation and smoke extraction smoother.

[0046] In another embodiment, the sunshade window mainly consists of a sunshade window body and a rotating shaft (including an upper rotating shaft 12 and a lower rotating shaft 16). The upper and lower ends of the hinged side of the sunshade window body are respectively hinged to the curtain wall beam 2 on the upper and lower hinged sides of the window frame via a rotating shaft. The second actuator is an electric casement door actuator (e.g., a casement window motor) used to drive the sunshade window body to rotate. Through the coordinated design of the sunshade window body, the rotating shaft, and the curtain wall beam 2, the overall structure is more rhythmic, avoiding the need for a separate window frame and saving on installation material costs.

[0047] In another embodiment, the sunshade window frame mainly consists of an aluminum alloy frame 11 and a sunshade film 10. The sunshade film 10 is made of a sunshade and light-transmitting film material. The sunshade film 10 is connected to the aluminum alloy frame 11 by tension and fixation, or by detachable connection (for example, the aluminum alloy frame 11 has a fixed edge inside, and the four sides of the sunshade film 10 are placed on the fixed edge inside the aluminum alloy frame 11, and then the movable pressure block is pressed onto the edge by screws or other detachable connectors). The upper and lower ends of the hinge side of the aluminum alloy frame 11 are respectively hinged to the curtain wall beam 2 on the upper and lower hinge sides of the window frame through a pivot. On the one hand, the design of the aluminum alloy frame 11 and the sunshade film 10 prevents outdoor heat radiation from entering the room during natural lighting, thereby reducing the use of central air conditioning and fresh air systems to regulate indoor temperature and effectively reducing the daily operating energy consumption of central air conditioning and fresh air systems. On the other hand, the installation of the sunshade film 10 is simpler and more operable due to the tension-fixed connection method. Alternatively, the sunshade film 10 can be detachably connected to the aluminum alloy frame 11, which facilitates the subsequent maintenance and replacement of the sunshade film 10.

[0048] In another embodiment, an outdoor curtain box 15 is also installed at the top of the window frame on the outdoor side, and the electric casement door actuator is hidden inside the outdoor curtain box 15. Of course, if the electric casement door actuator is also installed at the bottom of the window frame on the outdoor side, a structure similar to the outdoor curtain box 15 can be designed to hide the electric casement door actuator at the bottom of the window frame. For example, the electric casement door actuator (casement window motor 13) is mounted on a motor mounting box using M5x40 stainless steel pan head screws 14. The motor mounting box is mounted on the outer side of the curtain wall beam 2 using screws, and the motor mounting box is covered by the curtain wall beam cover 3 to protect the casement window motor 13. Of course, other existing connection methods that can protect the electric casement door actuator are still applicable without interfering with other structures in this embodiment. By installing the outdoor curtain box 15 and hiding the electric casement door actuator inside the outdoor curtain box 15, the electric casement door actuator is protected, increasing its service life.

[0049] The fire alarm control box can communicate with the first driver and the second driver, and the fire alarm control box is connected to the fire alarm system (FAS) via a fire signal line.

[0050] The integrated structural design of the switchable outdoor casement shading, ventilation, and natural smoke exhaust modes disclosed in this utility model can be connected to the station BAS system. It can control the angle of the outdoor shading film window in real time according to environmental data such as temperature and solar irradiance to achieve the shading function, effectively blocking ultraviolet rays and direct sunlight, preventing the "greenhouse effect", while maximizing the natural lighting capacity inside the building.

[0051] The integrated structural design of the switchable outdoor casement sunshade, ventilation and natural smoke exhaust modes disclosed in this utility model can also be connected to the station FAS system. According to the fire signal, it can prioritize the fire smoke exhaust needs in fire linkage. It controls the opening and closing of the outdoor casement sunshade window and electric smoke exhaust window, and can open them in time and synchronously to ensure the indoor fire natural smoke exhaust needs.

[0052] The integrated structural design of the switchable outdoor casement shading, ventilation and natural smoke exhaust modes disclosed in this utility model controls the opening and closing of the outdoor casement shading film window and the electric smoke exhaust window, which can provide daily indoor ventilation, reduce the use of central air conditioning and fresh air system, and effectively reduce daily operating energy consumption.

[0053] Example 2:

[0054] The other structures of this embodiment 2 are the same as those of embodiment 1, except that the sunshade film is multiple sheets, and the sunshade film is tensioned and fixed in a uniform and spaced manner or connected to the aluminum alloy frame 11 in a detachable manner along the thickness direction of the aluminum alloy frame 11.

[0055] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
