Description

Technical Field

[0001] This utility model relates to the field of building ventilation, and in particular to a concealed ventilation system for glass curtain walls. Background Technology

[0002] A glass curtain wall refers to an exterior building envelope or decorative structure that is supported by a structural system and can move relative to the main structure without sharing the loads of the main structure. It is an aesthetically pleasing and novel method of building wall decoration, a prominent feature of modern high-rise architecture. The wall can be single-pane or double-pane glass. It offers advantages such as being lightweight, aesthetically pleasing, less prone to pollution, and energy-saving. However, for super high-rise glass curtain wall buildings, indoor ventilation is challenging. Conventional operable windows pose a safety hazard at such heights, as they may fall. Furthermore, because the operable windows are exposed on the building facade, the curtain wall structure is less aesthetically pleasing from the outside. Therefore, more and more glass buildings are installing concealed windows for ventilation.

[0003] In the prior art, the utility model patent with application number 201720867948.6 and patent name "Hidden Inward Opening Ventilation Device for Unitized Curtain Wall" provides a glass curtain wall opening window. The opening window installed in this way is not visible from the outside, which enhances the aesthetics of the glass curtain wall. However, the opening window located inside occupies a large amount of indoor space, which poses a greater risk of bumping into people walking inside. At the same time, when people approach the glass curtain wall, the window sash extends outward for a long time, resulting in a poor user experience. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a glass curtain wall concealed ventilation system that has no exposed window sashes on the exterior facade, reduces the occupancy of indoor space, and improves the user's window opening experience.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is a concealed ventilation system for glass curtain walls, which includes several column assemblies. Each column assembly includes two adjacent sets of columns. A horizontal beam is vertically fixed on the column. An installation seat is fixed on the outer surface of the column. A pressure plate is fixed on the outer surface of the installation seat. A gap is formed between the pressure plate and the outer surface of the column. The gap is used to clamp and fix the edge of the glass.

[0006] An inwardly opening window is provided between two adjacent sets of columns. The opening windows are spaced apart along the extension direction of the columns and are located above the floor slab. The opening windows are fixed to the end of the columns near the outside.

[0007] A decorative panel is installed on the side of the operable window facing the outside, and the decorative panel is fixed to the outer facade of the two side pressure plates by a steel frame;

[0008] The decorative panel has ventilation holes at the height corresponding to the operable window.

[0009] The beneficial effects of the above technical solution are as follows: the mounting base can provide a gap between the column and the pressure plate, allowing the pressure plate to press and fix the glass from the outside. At the same time, the mounting base extends the outer facade of the column, allowing the operable window to be fixed at the end of the column near the outside. When the inward-opening operable window is opened, the window sash rotates between the columns. Compared with the part of the column that extends outward, the window sash is smaller, and most of the window sash can be hidden inside the column, reducing the space occupied by the operable window in the room. The curtain wall facade corresponding to the operable window is concealed by decorative panels, making the curtain wall more aesthetically pleasing from the outside. Natural wind can enter the room through the ventilation holes of the decorative panels and the opened operable window, thereby improving the indoor environment.

[0010] Furthermore, the operable window includes a window frame and a window sash. The end of the window frame facing the interior is fixed to the side of the column, and the end of the window frame facing the exterior is sealed to the pressure plate.

[0011] Beneficial effects: The pressure plate squeezes the glass from the outside while also squeezing the window frame, making the window frame more secure. The sealing and fixing can prevent air from entering through gaps and improve the thermal insulation effect of the glass curtain wall.

[0012] Furthermore, the pressure plate has two slots on the side facing the interior, the edge of the glass is fixed with a first strip that matches the slot, and the outer surface of the window frame is fixed with a second strip that matches the slot.

[0013] Beneficial effects: The clips and slots fit together and interlock, facilitating the installation of the pressure plate. At the same time, they enable the pressure plate to form a connection with the glass and window frame, enhancing the stability and sealing of the glass curtain wall.

[0014] Furthermore, a slot is provided on the pressure plate, the slot is located on the left side of the outer facade of the pressure plate, and a plug-in part is provided on the side of the decorative panel facing the interior. The plug-in part is adapted to be inserted into the slot, and the plug-in part is fastened by screws.

[0015] Beneficial effects: It provides a simple and convenient way to install decorative panels. When the pressure plate is fixed, the external fixing of the decorative panels is simple and convenient. The bolt tightening prevents the decorative panels from falling off and causing dangerous accidents.

[0016] Furthermore, an installation groove is provided on the pressure plate, the installation groove is located on the right side of the outer facade of the pressure plate, and the steel frame is fixedly connected in the installation groove.

[0017] Beneficial effects: The steel frame is used to support the decorative panels, enhance their structural strength, and prevent the panels from deforming when subjected to strong external winds.

[0018] Furthermore, the steel frame has a U-shaped cross-section, with the U-shaped opening facing the interior, and the interior-facing side is a hollow frame structure.

[0019] Beneficial effects: The hollow design of the U-shaped steel frame allows natural wind passing through the ventilation holes in the decorative panels to enter the openable windows. The exterior facade features an arc design at the bottom of the U-shape, which is both aesthetically pleasing and facilitates wind absorption.

[0020] Furthermore, the decorative panel is attached and fixed to the steel frame.

[0021] Beneficial effects: It integrates the decorative panel and the steel frame into a unified whole, further reinforcing the structure of the decorative panel and making it more robust and sturdy.

[0022] Furthermore, the ventilation holes are located on the left and right sides of the decorative panel perpendicular to the curtain wall, and no ventilation holes are provided on the decorative panel relative to the exterior of the curtain wall.

[0023] Beneficial effects: On the one hand, the porous facade is not aesthetically pleasing; on the other hand, it reduces the impact of rainfall, as rainwater is less likely to enter the curtain wall through ventilation holes on the left and right sides compared to the facade.

Detailed Implementation

[0030] The following describes in further detail a concealed ventilation system for glass curtain walls according to the present invention, with reference to the accompanying drawings and specific embodiments.

[0031] like Figure 1-5As shown, this utility model discloses a concealed ventilation system for glass curtain walls, comprising several column assemblies. Each column assembly includes two adjacent sets of columns 1. A horizontal beam 2 is vertically fixed to each column 1. An installation base 7 is fixed to the outer facade of each column 1. A pressure plate 8 is fixed to the outer facade of the installation base 7. A gap is formed between the pressure plate 8 and the outer facade of the column 1, which is used to clamp and fix the edge of the glass 3. An inwardly opening window 4 is provided between the two adjacent sets of columns 1. The opening windows 4 are spaced apart along the extension direction of the column 1 and are located above the floor slab 16. The opening windows 4 are fixed to the end of the column 1 near the outside. A decorative panel 6 is provided on the side of the opening window 4 facing the outside, which can form a facade effect without a suspended window. The decorative panel 6 is fixed to the outer facade of the pressure plates 8 on both sides by a steel frame 5. Ventilation holes 201 are provided on the decorative panel 6 at the height corresponding to the opening windows 4. Natural wind can enter the room through the ventilation holes 201 of the decorative panel 6 and the open opening windows 4, thereby improving the indoor environment.

[0032] In this embodiment, the mounting base 7 effectively extends the outer facade of the column 1 so that the outer facades of the glass 3 and the operable window 4 are flush. The operable window 4 includes a window frame 13 and a window sash 14. The front end of the window frame 13 is a decorative aluminum plate. The window sash 14 is opened by hardware fitting with the aluminum alloy window frame 13. The end of the window frame 13 facing the interior is fixed to the side of the column 1, and the end of the window frame 13 facing the exterior is sealed to the pressure plate 8, which can enhance the sealing and heat insulation of the glass curtain wall. Since the operable window 4 is installed at the end of the column 1 near the exterior, most of the window sash 14 can be hidden inside the column 1 when the operable window 4 is opened from the interior, reducing the space occupied by the operable window 4 in the interior.

[0033] Specifically, the pressure plate 8 has two slots 101 on the side facing the interior. The edge of the glass 3 is fixed with a first clip 11 that fits into the slot 101. The first clip 11 and the slot 101 fit together to form a connection between the pressure plate 8 and the glass 3. The outer facade of the window frame 13 is fixed with a second clip 12 that fits into the slot 101. The second clip 12 and the slot 101 fit together to form a connection between the pressure plate 8 and the window frame 13, improving the firmness of the glass 3 and the window frame 13. The pressure plate 8 has a slot 103 and a mounting groove 102. The slot 103 is located on the left side of the outer facade of the pressure plate 8, and the mounting groove 102 is located on the right side of the outer facade of the pressure plate 8. The decorative panel 6 has a plug-in part 23 on the side facing the interior. The plug-in part 23 fits into the slot 103 and is fastened with screws. The steel frame 5 is fixedly connected in the mounting groove 102.

[0034] In this embodiment, the steel frame 5 is made of L50*4 hot-dip galvanized angle steel, which is welded as a whole in the ground processing area. After being hoisted to the pre-installation position, it is fixed to the aluminum alloy pressure plate 8 by ST4.8*32 dovetail screws. The aluminum plate decorative strip extends 300mm beyond the finished surface of the glass 3. The decorative panel 6 is attached and fixed to the steel frame 5. After the insertion part 23 of the decorative panel 6 is matched and inserted into the slot 103 of the pressure plate 8, it is quickly fixed by self-tapping screws. An EPDM rubber strip is provided between the aluminum alloy pressure plate 8 and the glass 3 panel, and the outside is treated with glue.

[0035] In this embodiment, ventilation holes 201 are opened on the left and right sides of the decorative panel 6 perpendicular to the curtain wall. The decorative panel 6 does not have ventilation holes 201 relative to the exterior of the curtain wall. On the one hand, the exterior of the curtain wall is not aesthetically pleasing due to multiple holes. On the other hand, it reduces the impact of rainfall, as rainwater is less likely to enter the curtain wall from the left and right sides compared to the exterior.

[0036] The concealed ventilation system for glass curtain walls of this utility model has the following advantages: First, the operable window 4 is located on the interior side of the curtain wall, and the exterior facade of the curtain wall corresponding to the operable window 4 is covered and decorated by the decorative panel 6, so the open window sash 14 is not visible from the exterior facade of the curtain wall, enhancing the aesthetics of the glass curtain wall; Second, the operable window 4 is installed at the end of the column 1 away from the interior, and the window sash 14 rotates between the columns 1 after opening, with most of the window sash 14 hidden between the columns 1, occupying less interior space, improving the user experience while also avoiding the risk of people bumping into it; Third, the steel frame 5 can be prefabricated on the ground and then hoisted and fixed, thus modularizing the steel frame 5 and the decorative panel 6 as a whole, assembling the unit panels and then hoisting them, eliminating the need to erect scaffolding on the exterior wall of the building, improving the installation efficiency and safety of the curtain wall.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
