Curtain wall ventilation structure

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on June 25, 2023, with application number 202310751977.6 and invention name “A curtain wall ventilation structure”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present application relates to the technical field of building curtain walls, and in particular to a curtain wall ventilation structure. Background Art

[0004] The curtain wall is the exterior wall of a building. It does not bear weight and is a lightweight wall with decorative effects commonly used in modern large and high-rise buildings. The most common curtain wall is the glass curtain wall, which consists of a supporting structure and panel glass. It has a certain displacement ability relative to the main structure or a certain deformation ability itself. It is an outer protective wall of the building that does not bear the effects of the main structure. Existing glass curtain wall ventilation usually adopts curtain wall opening fan ventilation or mechanical equipment for ventilation. However, as the exterior wall enclosure structure of the building, the curtain wall is required to have good sealing, continuity and safety. If there are too many opening fans and the opening area is too large, it will not only affect the overall flatness of the exterior wall and increase the possibility of rainwater leakage, but also easily cause safety problems such as objects falling.

[0005] Summary of the Invention

[0006] This application aims to solve the technical problems of existing curtain wall ventilation structures, such as poor rainproof performance, poor flatness, low safety, and the need for mechanical equipment for ventilation, thereby providing a curtain wall ventilation structure.

[0007] To solve the above technical problems, the technical solutions of this application are as follows:

[0008] A curtain wall ventilation structure, comprising:

[0009] A glass exterior wall is provided outside the building, is inclined from top to bottom toward the inside of the building, and is provided with a plurality of recessed portions recessed toward the building from top to bottom, with adjacent recessed portions being interconnected via an inner sidewall of the glass exterior wall;

[0010] A bottom perforated aluminum plate is provided on the upper wall of the inner recess, connecting the interior and exterior of the building;

[0011] The facade perforated aluminum plate is arranged on the facade side wall of the inner recessed part, and is inclined downward toward the inner side of the building body, connecting the interior and the exterior of the building body.

[0012] Optionally, a plurality of the inner recesses are arranged in sequence at the same height around the circumference of the building.

[0013] Optionally, the inner recesses arranged at the same height are connected to each other through the circumferential inner side wall of the glass outer wall.

[0014] Optionally, the two adjacent recessed portions are respectively arranged above and below the floor slab, and a gap is reserved between the floor slab and the glass exterior wall.

[0015] Optionally, an inner wall is provided on the inner side of the glass outer wall, and an opening fan is provided on the inner wall.

[0016] Optionally, the lower end of the opening fan is a fixed end, and the upper end is a free end, and the upper end of the opening fan is inclined inward when opened.

[0017] Optionally, the height of the opening sash is set to correspond to the height of the facade perforated aluminum plate.

[0018] Optionally, a fireproof insulation layer is provided on the outer side of the inner wall.

[0019] Optionally, the glass exterior wall is connected to the building via a support frame.

[0020] Optionally, the perforation rate of the bottom perforated aluminum plate and the facade perforated aluminum plate is 45%.

[0021] The technical solution of this application has the following advantages:

[0022] 1. In existing curtain walls, the exterior walls are often opened to improve ventilation, but this can easily lead to accidents where objects or people fall through the openings. In the curtain wall ventilation structure provided by this application, the bottom and facade perforated aluminum panels on the inner recesses provide excellent ventilation. Air inside the building circulates to the outside through the bottom and facade perforated aluminum panels, improving the ventilation performance of the curtain wall. Arc-shaped ventilation channels are formed between adjacent inner recesses, accelerating air circulation and further improving the ventilation performance of the curtain wall. The curtain wall ventilation structure of this application not only maintains excellent ventilation performance, but also eliminates the need to open the exterior walls, resulting in a smoother overall exterior wall and no need to worry about objects or people falling through the curtain wall. Furthermore, the perforated aluminum panels are rigid and not prone to breakage. Both the glass exterior wall and the facade perforated aluminum panels are tilted downwards toward the inside of the building. When rainwater flows along the glass exterior wall to the junction with the inner recesses, it naturally falls and does not flow through the inner recesses into the curtain wall. When some rainwater is blown into the concave portion by the wind, it is difficult for the rainwater to enter the inner side of the curtain wall through the perforated aluminum panels on the facade because they are tilted downward from the top to the inside of the building. The curtain wall ventilation structure of the present application has good rainwater protection performance. The curtain wall ventilation structure of the present application has a simple structure and can be slightly modified from the conventional structure. The construction difficulty is low, and no mechanical equipment is required for ventilation. Natural ventilation is used, which is low-cost, simple to process, and does not consume additional energy.

[0023] 2. In the curtain wall ventilation structure provided in the present application, the inner recesses arranged at equal heights form an annular ventilation channel on the circumferential inner wall of the glass outer wall, and utilize the temperature difference on both sides of the building to form air convection. Without the assistance of mechanical equipment, the air circulation in the building is accelerated, thereby further improving the ventilation performance of the curtain wall.

[0024] 3. In the curtain wall ventilation structure provided in this application, the opening fan is arranged in the ventilation channel. Whether the opening fan is opened or not will not affect the appearance of the building. It is highly concealed, helps to unify the overall appearance of the curtain wall, and increase the continuity of the curtain wall.

[0025] 4. In the curtain wall ventilation structure provided in the present application, two adjacent recessed portions are respectively arranged above and below the floor slab. When the air circulates between the two adjacent recessed portions, the air above and below the floor slab (i.e., two different floors) can be ventilated, thereby improving the air circulation rate and heat exchange efficiency in the building, and helping to reduce the environmental differences between floors.

[0026] 5. In the curtain wall ventilation structure provided in this application, the inner wall prevents unnecessary safety accidents caused by contact between personnel and the glass exterior wall. The ventilation channel formed between the inner recess and the opening sash helps improve the ventilation of the curtain wall. When the opening sash is open, the upper end tilts inward, making it difficult for rainwater to pass through the opening sash, further improving rainproofing performance.

[0030] The following will clearly and completely describe the technical solution of this application in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0032] Example 1

[0033] A curtain wall ventilation structure provided in this embodiment, as shown in FIG1 , includes: a glass exterior wall 1 , a bottom perforated aluminum plate 2 , and a facade perforated aluminum plate 3 .

[0034] The glass exterior wall 1 is arranged on the outside of the building, and is inclined from top to bottom toward the inside of the building. The glass exterior wall 1 is provided with a plurality of inner recesses 9 arranged in sequence from top to bottom, which are recessed into the building. Adjacent inner recesses 9 are interconnected through the inner side wall of the glass exterior wall 1. The bottom perforated aluminum plate 2 is arranged on the upper wall of the inner recess 9, and the bottom perforated aluminum plate 2 connects the inside and outside of the building, and ventilation of the inside and outside of the building can be achieved through the bottom perforated aluminum plate 2. The facade perforated aluminum plate 3 is arranged on the facade side wall of the inner recess 9, and is inclined from top to bottom toward the inside of the building, and the facade perforated aluminum plate 3 connects the inside and outside of the building, and ventilation of the inside and outside of the building can be achieved through the facade perforated aluminum plate 3.

[0035] In existing curtain walls, in order to improve ventilation, the outer wall is opened, but this can easily cause safety accidents such as objects or people falling from the open area. In the curtain wall ventilation structure provided in this embodiment, the bottom perforated aluminum plate 2 and the vertical perforated aluminum plate 3 on the inner recess 9 have good ventilation. The air in the building circulates with the outside through the bottom perforated aluminum plate 2 and the vertical perforated aluminum plate 3, thereby improving the ventilation performance of the curtain wall. An arc-shaped ventilation channel is formed between adjacent inner recesses 9 (as indicated by the arrow B in FIG1 ), which accelerates the circulation of air and further improves the ventilation performance of the curtain wall. The curtain wall ventilation structure of this embodiment not only maintains good ventilation performance, but also does not require the outer wall to be opened. The overall outer wall is smoother, and there is no need to worry about objects or people falling from the curtain wall. It has good safety, and the perforated aluminum plate is rigid and not easy to break. The glass exterior wall 1 and the facade perforated aluminum plate 3 are both tilted downward toward the inside of the building. When rainwater flows along the glass exterior wall 1 to the connection with the inner recess 9, it will naturally fall and will not flow through the inner recess 9 to the inside of the curtain wall. When some rainwater is blown to the inner recess 9 by the wind, because the facade perforated aluminum plate 3 is tilted downward toward the inside of the building, it is difficult for rainwater to enter the inside of the curtain wall through the facade perforated aluminum plate 3. The curtain wall ventilation structure of this embodiment has good rainwater protection performance. The curtain wall ventilation structure of this embodiment is simple in structure and can be slightly modified from the conventional structure. The construction difficulty is low, and no mechanical equipment is required for ventilation. Natural ventilation is used, which is low in cost, simple in process, and does not consume additional energy.

[0036] Example 2

[0037] This embodiment, a further improvement on Example 1, features a plurality of concave portions 9 arranged at equal heights around the circumference of the building. These concave portions 9, arranged at equal heights, are interconnected via the circumferential inner wall of the glass exterior wall 1. This means that the inner side of the glass exterior wall 1 at the same height as the concave portions 9 is circumferentially connected. These concave portions 9, arranged at equal heights, form an annular ventilation channel along the circumferential inner wall of the glass exterior wall 1, allowing air to flow rapidly around the inner side of the glass exterior wall 1. This utilizes the temperature difference between the two sides of the building to generate air convection, accelerating air circulation within the building without the aid of mechanical equipment, further improving the ventilation performance of the curtain wall.

[0038] Two adjacent recesses 9 are located above and below floor slab 8, respectively, with a gap reserved between floor slab 8 and glass exterior wall 1. Air flowing between the two adjacent recesses 9 can ventilate both above and below floor slab 8 (i.e., two different floors), improving air circulation and heat exchange efficiency within the building and helping to reduce environmental differences between floors.

[0039] An inner wall 5 is provided on the inner side of the glass exterior wall 1, and an opening sash 6 is provided on the inner wall 5. The lower end of the opening sash 6 is a fixed end, and the upper end is a free end. When opened, the upper end of the opening sash 6 tilts inward. The height of the opening sash 6 is set to correspond to the height of the facade perforated aluminum plate 3. The provision of the inner wall 5 can prevent unauthorized personnel from directly contacting the glass exterior wall 1 and causing unnecessary safety accidents. A ventilation channel is formed between the inner recess 9 and the opening sash 6 (as indicated by the arrow A in Figure 1). Air circulates quickly through the inner recess 9 and the opening sash 6, which helps to improve the ventilation of the curtain wall. When the opening sash 6 is opened, the upper end tilts inward. If rain falls on the opening sash 6, it will flow down along the opening sash 6 to the outside of the opening sash 6 instead of entering the inside of the opening sash 6, which helps to further improve the rainproof performance. The opening sash 6 is set in the ventilation channel. Whether the opening sash 6 is opened or not will not affect the appearance of the building. It has strong concealment, helps to unify the overall appearance of the glass exterior wall 1, and increases the continuity of the glass exterior wall 1.

[0040] The outer side of the inner wall 5 is provided with a fireproof insulation layer 7, which can improve the fire resistance of the inner wall 5, reduce the heat exchange efficiency between the inner and outer sides of the inner wall 5, and reduce the energy consumption of the air conditioner.

[0041] The glass exterior wall 1 is connected to the building through a support frame 4. One end of the support frame 4 is connected to the inner wall 5 and the floor 8, and the other end is connected to the glass exterior wall 1 to prevent the glass exterior wall 1 from detaching and improve the connection stability between the glass exterior wall 1 and the building.

[0042] The perforation rate of the bottom perforated aluminum plate 2 and the facade perforated aluminum plate 3 is 45%, which increases the ventilation rate as much as possible without affecting the structural strength of the bottom perforated aluminum plate 2 and the facade perforated aluminum plate 3, helps air pass through the bottom perforated aluminum plate 2 and the facade perforated aluminum plate 3, and helps improve the ventilation performance of the curtain wall.

[0043] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of this application.
