Description

Technical Field

[0001] This utility model belongs to the field of glass curtain wall technology, specifically relating to a naturally ventilated glass curtain wall structure. Background Technology

[0002] A glass curtain wall is an exterior wall system consisting of glass panels and a supporting frame, typically used for the exterior walls of high-rise buildings. While glass curtain wall structures can effectively meet the requirements of building lighting and aesthetics, their good sealing properties significantly affect the airflow between the inside and outside of the building.

[0003] In existing technologies, top-hung windows are mostly used to directly open on glass curtain walls to achieve ventilation. However, traditional top-hung windows can easily cause safety accidents if the opening is too large, while opening them too small will reduce ventilation. Furthermore, traditional top-hung windows usually require frequent manual opening and closing, which is inconvenient and makes it difficult to achieve a continuous and good ventilation effect. In addition, some top-hung windows are large, making them difficult to open. Excessive force can easily damage the hinges of the opening and closing parts, greatly reducing the service life of the glass curtain wall. Utility Model Content

[0028] Please refer to the following: Figures 1 to 6 The present invention provides a naturally ventilated glass curtain wall structure. The naturally ventilated glass curtain wall structure includes a supporting frame 1 connected to the outside of the building and several first glass curtain panels 2 and second glass curtain panels 3 arranged at intervals on the supporting frame 1. The first glass curtain panels 2 are arranged vertically, and the second glass curtain panels 3 are gradually inclined outwards from top to bottom. A window frame 4 connects the lower end of the second glass curtain panel 3 to the supporting frame 1. The second glass curtain panels 3, the window frame 4, and the supporting frame 1 enclose a ventilation cavity 5 that communicates with the interior of the building. Several louvers 6 are arranged at intervals within the window frame 4, and the louvers 6 are used to supply outside air into the ventilation cavity 5.

[0029] This embodiment provides a naturally ventilated glass curtain wall structure. Compared with the prior art, it utilizes an inclined second glass curtain panel 3 and a window frame 4 connected between the lower end of the second glass curtain panel 3 and the supporting frame 1 to form a fixed ventilation cavity 5 between the second glass curtain panel 3 and the supporting frame 1. Louvers 6 installed on the window frame 4 introduce external airflow into the ventilation cavity 5 from the bottom, thereby providing continuous fresh air to the building interior. This design effectively ensures indoor ventilation, eliminates the need for opening and closing windows, reduces reliance on manual intervention for ventilation, avoids light pollution caused by frequent window opening and closing, and helps reduce safety hazards and extend the service life of the glass curtain wall.

[0030] In this embodiment, both the window frame 4 and the louvers 6 are made of aluminum alloy and are treated with fluorocarbon coating, which gives the window frame 4 and the louvers 6 exposed to the outside of the building excellent UV resistance. They can maintain color stability and are not easy to fade under long-term sun and rain exposure. In addition, the aluminum alloy material is lightweight, which can increase the stability and safety of the glass curtain wall structure.

[0031] Furthermore, when the second glass curtain wall panel 3 is located at a lower floor level, a safety railing 13 can be installed within the supporting frame 1 to prevent unauthorized personnel from approaching the glass curtain wall and to protect personnel safety. Additionally, a protective net (not shown in the figure) can be installed below the window frame 4 to prevent debris from falling and to effectively block mosquitoes.

[0032] The first glass curtain panel 2 is connected to the supporting frame 1 using a conventional connection method. The first glass curtain panel 2 is made of hollow laminated tempered glass, giving it good heat insulation, sound insulation, and high safety performance. The location and number of the second glass curtain panels 3 are determined according to the building's indoor ventilation requirements. The second glass curtain panels 3 are also made of laminated tempered glass.

[0033] As a specific embodiment of a naturally ventilated glass curtain wall structure provided by this utility model, see [link to relevant documentation]. Figure 1 and Figure 2 The second glass curtain wall 3 is connected to the support frame 1 by a glass side panel 7, and the lower end of the glass side panel 7 is connected to the window frame 4.

[0034] In this embodiment, the lower end of the second glass curtain wall 3 is tilted outward, so that a triangular opening is formed between the left and right sides of the second glass curtain wall 3 and the supporting frame 1. The glass side panel 7 can fill the opening, which helps to increase the stability of the glass curtain wall while meeting the appearance requirements.

[0035] As a specific embodiment of a naturally ventilated glass curtain wall structure provided by this utility model, see [link to relevant documentation]. Figure 3The tilt angle of the second glass curtain panel 3 is 10°-20°.

[0036] In this embodiment, Figure 3 The angle 'a' shown is the tilt angle of the second glass curtain panel 3. This angle is limited to 10°-20° to ensure both ventilation and aesthetic requirements are met, without affecting the stability of the glass curtain wall. The tilt angle (angle 'a') of the second glass curtain panel 3 is preferably 15°.

[0037] As a specific embodiment of a naturally ventilated glass curtain wall structure provided by this utility model, see [link to relevant documentation]. Figure 3 The support frame 1 includes several columns 11 and beams 12. The columns 11 are arranged at intervals in the horizontal direction, and the beams 12 are arranged at intervals on the columns 11 in the vertical direction. The inner edge of the window frame 4 is connected to one of the beams 12. The upper end of the second glass curtain panel 3 is connected to the previous beam 12 through a fixing component 8, and the lower end is connected to the outer edge of the window frame 4 through a fixing component 8.

[0038] In this embodiment, several columns 11 and beams 12 are assembled to form a grid-like support frame 1. The first glass curtain wall panel 2 and the second glass curtain wall panel 3 are connected at intervals within the grid of the support frame 1, so that the support frame 1, the first glass curtain wall panel 2 and the second glass curtain wall panel 3 form an integral glass curtain wall. Both the columns 11 and the beams 12 are made of aluminum alloy profiles.

[0039] The inner edge of the window frame 4 is connected to one of the crossbeams 12 by high-strength stainless steel bolts, and the outer edge is connected to the lower end of the second glass curtain panel 3 by the fixing component 8. The upper end of the second glass curtain panel 3 is connected to the previous crossbeam 12 by the fixing component 8, thereby forming a stable triangular structure between the second glass curtain panel 3, the window frame 4 and the supporting frame 1.

[0040] As a specific embodiment of a naturally ventilated glass curtain wall structure provided by this utility model, see [link to relevant documentation]. Figure 4 The fixing component 8 includes a U-shaped clamp 81, a fastening bolt 82, and an elastic pad 83. The U-shaped clamp 81 is connected to the window frame 4 or the crossbeam 12. The edge of the second glass curtain panel 3 is inserted into the U-shaped opening of the U-shaped clamp 81. The fastening bolt 82 passes through the U-shaped clamp 81 and the second glass curtain panel 3. The elastic pad 83 is located between the second glass curtain panel 3 and the inner sidewall of the U-shaped clamp 81.

[0041] In this embodiment, the U-shaped clamp 81 is connected to the window frame 4 or the crossbeam 12 by stainless steel screws. The upper or lower edge of the second glass curtain panel 3 is inserted into the U-shaped opening of the U-shaped clamp 81, and then the second glass curtain panel 3 is fixedly connected to the U-shaped clamp 81 by fastening bolts 82 and nuts. The fastening bolts 82 are stainless steel bolts. The elastic pad 83 is a rubber pad to prevent the second glass curtain panel 3 from being damaged by excessive tightening force of the fastening bolts 82.

[0042] As a specific embodiment of a naturally ventilated glass curtain wall structure provided by this utility model, see [link to relevant documentation]. Figure 4 The two ends of the louver 6 are rotatably connected to the two opposite inner walls of the window frame 4 through the rotating shaft 63. One end of the louver 6 is connected to the drive assembly 9, which is used to drive the louver 6 to rotate around the rotating shaft 63 to adjust the opening of the louver 6.

[0043] In this embodiment, the louver 6 is rotatably connected to the window frame 4, which facilitates the adjustment of the installation angle of the louver 6, thereby adjusting the ventilation volume. By setting a drive component 9 at one end of the louver 6, multiple louvers 6 can be adjusted simultaneously, improving the efficiency of ventilation volume adjustment.

[0044] As a specific embodiment of a naturally ventilated glass curtain wall structure provided by this utility model, see [link to relevant documentation]. Figure 4 or Figure 5 The louver 6 includes a straight section 61 and a bent section 62 connected to one side of the straight section 61, and the rotating shaft 63 is rotatably engaged with the straight section 61.

[0045] In this embodiment, a bent section 62 inclined to one side is provided on the louver 6, which helps to increase the flow path of airflow through the louver 6, reduce the airflow velocity, reduce the kinetic energy of the airflow, and thus reduce noise generation. Specifically, the extension direction of the bent section 62 is opposite to the rotation direction when the opening of the louver 6 decreases, such as... Figure 4 or Figure 5 The louver 6 shown is in an open ventilation state. When it is necessary to rotate the louver 6 to reduce the opening of the louver 6 or to close the louver 6, the drive assembly 9 will drive the louver 6 to rotate in a counterclockwise direction. Then the bending section 62 extends clockwise from the side wall of the straight section 61. In this way, the setting of the bending section 62 will not interfere with the rotation adjustment of the louver 6.

[0046] As a specific embodiment of a naturally ventilated glass curtain wall structure provided by this utility model, see [link to relevant documentation]. Figure 4 The drive assembly 9 includes a linkage rod 91, a push-pull rod 92, and a drive component. The linkage rod 91 extends along the arrangement direction of the louvers 6 and is hinged to several louvers 6 respectively. The push-pull rod 92 is slidably connected to the window frame 4 and is hinged to the linkage rod 91 through an intermediate connecting rod 93. The drive component is connected to the push-pull rod 92 to drive the push-pull rod 92 to slide and translate, and to drive the louvers 6 to rotate through the linkage rod 91.

[0047] In this embodiment, the rotating shaft 63 is located in the middle of the straight section 61, and the hinge point between the louver 6 and the linkage rod 91 is located on the side of the rotating shaft 63 away from the bent section 62. The driving component drives the push-pull rod 92 to slide outward, and the push-pull rod 92 pushes the linkage rod 91 outward through the intermediate connecting rod 93, thereby causing the louver 6 to rotate counterclockwise around the rotating shaft 63 to reduce the opening of the louver 6 and reduce the ventilation volume. Conversely, the driving component drives the push-pull rod 92 to slide inward and retract, and the linkage rod 91 moves inward accordingly, thereby causing the louver 6 to rotate clockwise around the rotating shaft 63 to increase the opening of the louver 6 and increase the ventilation volume.

[0048] The hinged arrangement of the push-pull rod 92, the linkage rod 91 and the intermediate connecting rod 93 can adapt to the positional changes caused by the rotation of the louver 6, thus improving the practicality of the drive assembly 9.

[0049] As a specific embodiment of a naturally ventilated glass curtain wall structure provided by this utility model, see [link to relevant documentation]. Figure 5 The driving component includes a gear 94 rotatably connected to the window frame 4 and a rack 95 connected to the push-pull rod 92. The rack 95 extends along the sliding direction of the push-pull rod 92 and meshes with the gear 94.

[0050] In this embodiment, by utilizing the meshing action of gear 94 and rack 95, rotating gear 94 can achieve stable translation of push-pull rod 92.

[0051] As a specific embodiment of a naturally ventilated glass curtain wall structure provided by this utility model, see [link to relevant documentation]. Figure 6 A housing 96 for accommodating gear 94 is connected to the window frame 4. A push-pull rod 92 is slidably connected inside the housing 96. Gear 94 is rotatably engaged with housing 96. A drive motor 97 is connected to the outer wall of housing 96. The drive end of drive motor 97 is connected to gear 94.

[0052] In this embodiment, the housing 96 provides a mounting carrier for the push-pull rod 92 and the gear 94, facilitating the installation of the drive assembly 9. The drive motor 97 drives the gear 94 to rotate, thereby enabling the sliding translation of the push-pull rod 92 and thus adjusting the opening degree of the louver 6.

[0053] Furthermore, a controller and a timer can be installed on the housing 96. The drive motor 97 and the timer are electrically connected to the controller. The timer is used to time the opening time of the louvers 6, and the controller is used to control the drive motor 97 according to the set time period and the set air volume, thereby realizing the timed opening and closing of the louvers 6 and the automatic adjustment of the air volume. This allows the ventilation effect of the glass curtain wall structure to be free from human intervention and ensures good indoor ventilation.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
