A curtain wall ventilation structure

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the priority of 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

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

Background Art

The curtain wall is the outer wall of the building. It is non-load-bearing 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 is composed of a supporting structure and panel glass. It has a certain displacement ability relative to the main structure or a certain deformation ability of its own. 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 uses curtain wall opening fans for ventilation or mechanical equipment for ventilation. However, as the outer 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 outer wall and increase the possibility of rainwater leakage, but also easily cause safety problems such as objects falling.

Summary of the invention

The present application aims to solve the technical problems that the existing curtain wall ventilation structure has poor rainproof performance, poor flatness, low safety, and requires mechanical equipment for ventilation, thereby providing a curtain wall ventilation structure.

To solve the above technical problems, the technical solution of this application is as follows:

A curtain wall ventilation structure, comprising:

The glass outer wall is arranged outside the building, and is inclined from top to bottom toward the inner side of the building. A plurality of inner recesses arranged toward the building are arranged in sequence from top to bottom, and the adjacent inner recesses are connected by the glass outer wall. The inner walls are interconnected;

A bottom perforated aluminum plate is arranged on the upper wall of the inner recessed portion, connecting the inside and the outside of the building;

The facade perforated aluminum plate is arranged on the facade side wall of the inner recessed part, and is inclined from top to bottom toward the inner side of the building body, so as to connect the inside and the outside of the building body.

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

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.

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

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.

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.

Optionally, the height of the opening sash is set corresponding to the height of the facade perforated aluminum plate.

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

Optionally, the glass exterior wall is connected to the building via a supporting frame.

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

The technical solution of this application has the following advantages:

1. In the existing curtain wall, in order to improve ventilation, the outer wall will be opened, but this is easy to cause safety accidents such as objects or people falling from the opening. In the curtain wall ventilation structure provided by the present application, the bottom perforated aluminum plate and the facade perforated aluminum plate on the inner concave part have good ventilation, and the air in the building body circulates with the outside through the bottom perforated aluminum plate and the facade perforated aluminum plate, thereby improving the ventilation performance of the curtain wall. An arc-shaped ventilation channel is formed between adjacent inner concave parts, which accelerates the circulation of air and further improves the ventilation performance of the curtain wall. The curtain wall ventilation structure of the present application not only maintains good ventilation performance, but also does not need to open the outer wall, and 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 outer wall and the facade perforated aluminum plate are both inclined from top to bottom toward the inside of the building body. When rainwater flows along the glass outer wall to the connection with the inner concave part, it will fall naturally and will not flow to the inside of the curtain wall through the inner concave part. When some rainwater is blown to the inner concave part by the wind, because the facade perforated aluminum plate is inclined from top to bottom toward the inner side of the building, it is difficult for rainwater to enter the inner side of the curtain wall through the facade perforated aluminum plate. The curtain wall ventilation structure of the present application has good rainproof performance. The curtain wall ventilation structure of the present application has a simple structure and can be slightly modified on the conventional structure. The construction difficulty is low, and there is no need to use mechanical equipment for ventilation. Natural ventilation is adopted, which has low cost, simple process and no additional energy consumption.

2. In the curtain wall ventilation structure provided in the present application, the inner recessed parts arranged at the same height form an annular ventilation channel on the circumferential inner wall of the glass outer wall, and the temperature difference on both sides of the building is used 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.

3. In the curtain wall ventilation structure provided in the present 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 has strong concealment, helps to unify the overall appearance of the curtain wall, and increase the continuity of the curtain wall.

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.

5. In the curtain wall ventilation structure provided by the present application, the inner wall can prevent people from contacting the glass outer wall and causing unnecessary safety accidents. A ventilation channel is formed between the inner concave part and the opening fan, which helps to improve the ventilation of the curtain wall. When the opening fan is opened, the upper end is tilted inward, and rainwater is not easy to pass through the opening fan, which helps to further improve the rainproof performance.

Example 1

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 vertical perforated aluminum plate 3 .

The glass exterior wall 1 is arranged outside 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 concave toward the building in sequence from top to bottom, and adjacent inner recesses 9 are connected to each other 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 the inside and outside of the building can be ventilated 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 the inside and outside of the building can be ventilated through the facade perforated aluminum plate 3.

In the existing curtain wall, in order to improve ventilation, the outer wall will be opened, but this is likely to cause safety accidents such as objects or people falling from the opening. 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 concave part 9 have good ventilation. The air in the building body circulates with the outside through the bottom perforated aluminum plate 2 and the vertical perforated aluminum plate 3, which improves the ventilation performance of the curtain wall. An arc-shaped ventilation channel (as indicated by the arrow B in Figure 1) is formed between adjacent inner concave parts 9, which speeds up 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 need to open the outer wall. The overall structure of the 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 outer wall 1 and the facade perforated aluminum plate 3 are both arranged to be inclined from top to bottom toward the inner side of the building. When rainwater flows along the glass outer wall 1 to the connection with the inner recess 9, it will fall naturally and will not flow to the inner side of the curtain wall through the inner recess 9. When part of the rainwater is blown to the inner recess 9 by the wind, because the facade perforated aluminum plate 3 is arranged to be inclined from top to bottom toward the inner side of the building, it is difficult for rainwater to enter the inner side of the curtain wall through the facade perforated aluminum plate 3. The curtain wall ventilation structure of this embodiment has good rainproof performance. The curtain wall ventilation structure of this embodiment has a simple structure and can be slightly modified on the conventional structure. The construction difficulty is low, and there is no need to use mechanical equipment for ventilation. Natural ventilation is adopted, which has low cost, simple process and no additional energy consumption.

Example 2

This embodiment is a further improvement of the embodiment 1. A plurality of inner recesses 9 are arranged in order of equal height around the circumference of the building. The inner recesses 9 arranged at the same height are connected to each other through the circumferential inner wall of the glass outer wall 1. That is to say, the inner side of the glass outer wall 1 at the same height as the inner recesses 9 is connected in the circumferential direction, and the inner recesses 9 arranged at the same height form an annular ventilation channel on the circumferential inner wall of the glass outer wall 1, so that air can flow quickly in the circumferential direction of the inner side of the glass outer wall 1, and air convection is formed by utilizing the temperature difference on both sides of the building body, which accelerates the air circulation in the building body without the assistance of mechanical equipment, and further improves the ventilation performance of the curtain wall.

Two adjacent inner recesses 9 are respectively arranged above and below the floor 8, and a gap is reserved between the floor 8 and the glass outer wall 1. When air flows between the two adjacent inner recesses 9, the upper and lower parts of the floor 8 (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 difference in environment between floors.

An inner wall 5 is provided on the inner side of the glass outer wall 1, and an opening fan 6 is provided on the inner wall 5. The lower end of the opening fan 6 is a fixed end, and the upper end is a free end. When the opening fan 6 is opened, the upper end of the opening fan 6 is tilted inward. The height of the opening fan 6 is set corresponding to the height of the facade perforated aluminum plate 3. The inner wall 5 can prevent irrelevant personnel from directly contacting the glass outer wall 1 and causing unnecessary safety accidents. A ventilation channel (as indicated by the arrow A in FIG. 1) is formed between the inner concave portion 9 and the opening fan 6. The air quickly circulates through the inner concave portion 9 and the opening fan 6, which helps to improve the ventilation of the curtain wall. When the opening fan 6 is opened, the upper end is tilted inward. If rain falls on the opening fan 6, it will flow down along the opening fan 6 to the outside of the opening fan 6, and will not enter the inside of the opening fan 6, which helps to further improve the rainproof performance. The opening fan 6 is set in the ventilation channel. Whether the opening fan 6 is opened or not will not affect the appearance of the building. It has strong concealment, which helps to unify the overall appearance of the glass outer wall 1 and increase the continuity of the glass outer wall 1.

The outer side of the inner wall 5 is provided with a fireproof heat-insulating 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.

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.

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.

Obviously, the above embodiments are only examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the protection scope of the present application.
