Description

Technical Field

[0001] This application relates to the technical field of building curtain walls, and particularly to a curtain wall system. Background Art

[0002] Due to its good permeability and generous and bright overall appearance, glass curtain walls are very commonly used in large public buildings and high-end residential buildings.

[0003] In existing building solutions, there are many building facades that adopt an oblique grid structure to form a curtain wall system composed of several units. The oblique grid structure is a new structural system with inclined columns as the main basic components, which intersect obliquely to form a grid. The oblique grid structure has the advantages of beautiful appearance, reliable force-bearing, and good lateral strength. Therefore, the oblique grid structure is becoming more and more popular and is often used in high-rise buildings.

[0004] However, the oblique grid structure also has problems such as complex construction. Especially in order to form the facade shape of the fold angle in the curtain wall system, a large number of sharp-cornered glasses, especially triangular glasses, are required. Although sharp-cornered glasses can be specially customized and processed, the finished product rate is very low, and the loss rate is large during transportation and installation. Summary of the Invention

[0005] An embodiment of this application provides a curtain wall system, and the main purpose is to reduce the material loss on the premise of ensuring the facade shape of the fold angle in the curtain wall system.

[0006] To achieve the above object, the embodiment of this application adopts the following technical solutions:

[0007] A curtain wall system includes columns, a curtain wall, a first shielding member, and a second shielding member. The columns are used to be installed on the outer side of a building. The curtain wall is installed on the columns. The curtain wall is a transparent curtain wall. The first shielding member is installed on the side of the curtain wall away from the building. The first shielding member extends along the height direction of the building. The second shielding member is installed on the side of the curtain wall away from the building. The second shielding member extends along the height direction of the building. The first shielding member and the second shielding member intersect and form an included angle. The first shielding member and the second shielding member respectively shield part of the curtain wall, so that the part of the curtain wall within the included angle is exposed and forms a triangular shape.

[0008] A curtain wall system provided by an embodiment of the present application. The curtain wall is installed on columns to form the outer facade of a building. By installing a first shielding member and a second shielding member on the side of the curtain wall away from the building respectively, the first shielding member can shield a corresponding part of the curtain wall, and the second shielding member can also shield a corresponding part of the curtain wall. Since the first shielding member and the second shielding member intersect and form an included angle, the part of the curtain wall not shielded by the first shielding member and the second shielding member, that is, the exposed part of the curtain wall, is within the included angle, making the exposed part of the curtain wall present a triangular shape within the included angle. Therefore, there is no need to specially customize and process the glass into triangular glass. On the premise of ensuring the vertical surface shape of the fold angle in the curtain wall system, it effectively avoids the loss during the production or transportation process after being processed into triangular glass.

[0009] In some possible embodiments of the present application, the first shielding member includes a first side portion, a second side portion, and a third side portion; the second side portion faces the curtain wall to shield a part of the curtain wall; the first side portion, the second side portion, and the third side portion are sequentially connected end to end to form a structure with a triangular cross-section; wherein, the cross-section is a plane perpendicular to the curtain wall.

[0010] The cross-section of the first shielding member is a triangular structure. Because a triangle has certain force stability, when the first shielding member is installed outside the curtain wall, the possibility of deformation of the first shielding member is reduced in case of typhoon or stormy weather; at the same time, the triangular structure can also increase the three-dimensional shape of the outer facade of the building; in addition, by using the second shielding member to shield a part of the curtain wall, the exposed part of the curtain wall forms a triangular shape.

[0011] In some possible embodiments of the present application, any one of the first side portion and the second side portion includes a plurality of baffles and a plurality of cross bars. The plurality of cross bars are arranged at intervals along the height direction of the building. The baffles are connected to the cross bars, and the gaps formed between every two adjacent cross bars are shielded by the baffles.

[0012] The height of a building is usually relatively high, especially for high-rise buildings. By arranging a plurality of cross bars at intervals along the height direction of the building and connecting the baffles to the cross bars to shield the gaps formed between every two adjacent cross bars, it is convenient to form the first side portion and the second side portion on high-rise buildings.

[0013] In some possible embodiments of the present application, the first shielding member further includes a first vertical rod, a second vertical rod, and a third vertical rod; the first vertical rod, the second vertical rod, and the third vertical rod are parallel to each other and all extend along the height direction of the building; the first vertical rod and the third vertical rod are closer to the curtain wall relative to the second vertical rod; the first vertical rod and the second vertical rod, and multiple cross bars and multiple baffles connected between the first vertical rod and the second vertical rod form a first side portion; the second vertical rod and the third vertical rod, and multiple cross bars and multiple baffles connected between the second vertical rod and the third vertical rod form a second side portion; a third side portion is formed between the first vertical rod and the third vertical rod.

[0014] By connecting the cross bars between the first vertical rod and the second vertical rod, it is convenient to install multiple cross bars between the first vertical rod and the second vertical rod along the height direction of the building to form the framework of the first side portion; by connecting the cross bars between the second vertical rod and the third vertical rod, it is convenient to install multiple cross bars between the second vertical rod and the third vertical rod along the height direction of the building to form the framework of the second side portion; in addition, the second vertical rod is respectively connected to the cross bars of the first side portion and the cross bars of the second side portion, which is convenient for connecting the ends of the first side portion and the second side portion.

[0015] In some possible embodiments of the present application, light grooves are formed on both the first vertical rod along its extending direction and the third vertical rod along its extending direction.

[0016] By providing the light grooves, it is convenient to install outline lights or landscape lights on the outer facade of the building to outline the building at night. In addition, by installing landscape lights, the building can be decorated through light and shadow changes at night.

[0017] In some possible embodiments of the present application, the columns include a first column, a second column, and a third column, and all extend along the height direction of the building; a cross beam is connected between the first column and the third column; the second column is opposite to the cross beam and is arranged opposite to the second vertical rod; the curtain wall is installed in the gap formed between the first column and the second column; a first ventilation duct communicating with the inside of the building is formed between the second column and the third column; the third column is connected with a first connecting rod, and one end of the first connecting rod far away from the third column is connected to the first vertical rod; a second ventilation duct communicating with the first ventilation duct is formed between the first vertical rod and the third column, and the second ventilation duct communicates with the outside of the building.

[0018] Through the cross beam, it is convenient to connect the first column and the second column, so that the first column and the second column form an integral body; the flowing air outside the building sequentially passes through the second ventilation duct and the first ventilation duct and enters the inside of the building, thereby facilitating the indoor ventilation of the building.

[0019] In some possible embodiments of the present application, the first upright column and the third upright column are arranged away from the first shielding member relative to the second upright column. Second upright columns are arranged on both sides of the first upright column. Curtain walls are connected between the first upright column and each of the two second upright columns. A fold angle is formed between the two curtain walls respectively connected by the first upright column. A third ventilation duct is formed between the first upright column and the third upright column. Two ends of the third ventilation duct are respectively communicated with the first ventilation duct and the inside of the building.

[0020] By forming a fold angle between the two curtain walls respectively connected by the first upright column, on the one hand, the facade effect of the building facade is increased, and on the other hand, the area of the curtain wall is increased, facilitating light to shine into the interior of the building; in addition, the first upright column and the third upright column are arranged away from the first shielding member relative to the second upright column, and the connection line between the first upright column and the third upright column is not parallel to the connection line between the first upright column and the second upright column, reducing the area of the curtain wall between the first upright column and the second upright column that shields the third ventilation duct, which is beneficial to the ventilation of the third ventilation duct towards the inside of the building.

[0021] In some possible embodiments of the present application, an opening fan that shields the third ventilation duct is installed in the third ventilation duct. The opening fan is connected to the first upright column. When the opening fan is opened, two ends of the third ventilation duct are respectively communicated with the first ventilation duct and the inside of the building.

[0022] By providing the opening fan, when the opening fan is opened, two ends of the third ventilation duct are respectively communicated with the first ventilation duct and the inside of the building; when the opening fan is closed, the opening fan shields the third ventilation duct, thereby facilitating the control of the ventilation inside the building.

[0023] In some possible embodiments of the present application, a first ventilation plate is connected to the first connecting rod. The first ventilation plate covers the second ventilation duct. A plurality of first ventilation holes penetrate through the first ventilation plate. Two ends of the first ventilation hole are respectively communicated with the second ventilation duct and the outside of the building.

[0024] The flowing air outside the building enters the second ventilation duct through the first ventilation holes, without affecting the ventilation of the second ventilation duct; by shielding the second ventilation duct with the first ventilation plate, on the one hand, the influence on the appearance of the building facade caused by too large gaps in the second ventilation duct is reduced, and on the other hand, the entry of sundries into the second ventilation duct along with the air flow is reduced.

[0025] In some possible embodiments of the present application, a fourth ventilation duct is formed between the third vertical rod and the curtain wall. Two ends of the fourth ventilation duct are respectively communicated with the first ventilation duct and the outside of the building. The third vertical rod is connected with a second connecting rod towards the curtain wall. A second ventilation plate is connected to the second connecting rod. The second ventilation plate covers the fourth ventilation duct. A plurality of second ventilation holes penetrate through the second ventilation plate. Two ends of the second ventilation hole are respectively communicated with the fourth ventilation duct and the outside of the building.

[0026] A fourth ventilation duct communicating with the first ventilation duct is formed between the third vertical rod and the curtain wall, increasing the air intake of the first ventilation duct, thereby increasing the air intake inside the building; the flowing air outside the building enters the fourth ventilation duct through the second ventilation holes, without affecting the ventilation of the fourth ventilation duct; then, the fourth ventilation duct is blocked by the second ventilation plate, on the one hand, reducing the impact on the appearance of the building facade due to excessive gaps in the fourth ventilation duct, and on the other hand, reducing the entry of sundries into the fourth ventilation duct along with the air flow.

Detailed implementation manners

[0036] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0037] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0038] The terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0039] In the description of the present application, it should be noted that, unless otherwise clearly defined and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0040] Figure 1 The schematic diagram of the outer side structure of a curtain wall system is shown. Figure 2 Shown is Figure 1Cross-sectional view in the C-C direction, where A represents the outer side of the building and B represents the inner side of the building. In combination with Figure 1 and Figure 2 , the building is provided with multiple floors along the height direction L of the building. The floors include a suspended ceiling board 19 and a floor surface layer 20. The suspended ceiling board 19 and the floor surface layer 20 of each floor are arranged from top to bottom, and an internal space of one floor is formed between the suspended ceiling board 19 and the floor surface layer 20.

[0041] In order to make the overall appearance of the building generous and bright, a curtain wall 2 is installed outside each floor along the height direction L of the building. Moreover, in order to make the building have advantages such as reliable force-bearing and good lateral strength resistance, the outer facades of many existing buildings adopt an oblique grid structure to form a curtain wall system composed of several units. The oblique grid structure is a new type of structural system with inclined columns as the main basic components and forming a grid by intersecting obliquely. Therefore, the oblique grid structure is becoming more and more popular and is often used in high-rise buildings.

[0042] However, the oblique grid structure also has problems such as complex construction. Especially in order to form the facade shape of the fold angle in the curtain wall system, a large amount of sharp-corner glass, especially triangular glass, is required. Although the sharp-corner glass can be specially customized and processed, the finished product rate is very low, and the loss rate is large during the transportation and installation process.

[0043] Continue to refer to Figure 1 , in order to achieve the effect of the sharp-corner glass in the curtain wall system, metal materials can be used to replace the glass. By customizing the metal materials in the factory, the metal materials are processed into a triangular shape to replace the sharp-corner glass, thereby forming the facade shape of the fold angle in the curtain wall system.

[0044] In some embodiments, the metal material can be an aluminum single board or a stainless steel board.

[0045] In addition, by using metal materials to replace the sharp-corner effect of the glass shape, because the appearance of the metal materials is inconsistent with other glass materials in the curtain wall system, a large number of "patches" will be caused to the outer facade of the building, which will damage the integrity of the outer facade of the building. At the same time, cracks will also occur at the sharp corners during the production or transportation of the metal materials made into a triangular shape.

[0046] Therefore, in order to ensure the facade shape of the fold angle in the curtain wall system, reduce the material loss, and improve the integrity of the outer facade of the building, the present application provides a curtain wall system, Figure 3 shows a front view of a partial structure of a curtain wall system. Specifically, refer to Figure 3, the curtain wall system includes columns 1, curtain walls 2, a first shielding member 3, and a second shielding member 4. The setting direction of the columns 1 can have various situations. In this application, the setting direction of the columns 1 is parallel to the height direction L of the building, and multiple columns 1 are arranged at intervals along a direction perpendicular to the height direction L of the building.

[0047] In some embodiments, the columns 1 can be made of aluminum alloy or stainless steel.

[0048] Connection steel plates connected to the columns are embedded in the outer wall of the building. There are various situations for the connection method between the columns 1 and the connection steel plates on the outer wall of the building. By way of example, the columns 1 can be directly welded to the connection steel plates, or the columns 1 can be bolted to the connection steel plates.

[0049] Refer to Figure 3 , the curtain walls 2 are installed on the columns 1. The curtain walls 2 are transparent curtain walls 2. Specifically, the curtain walls 2 can be insulating tempered Low-E glass. Multiple curtain walls 2 can be laid side by side on the columns 1 along the height direction L of the building, or laid side by side on the columns 1 along a direction perpendicular to the height direction L of the building to form the outer facade of the building.

[0050] In some embodiments, each curtain wall 2 can be trapezoidal or rectangular and meet the minimum cutting size of 300 mm.

[0051] Continuing to refer to Figure 3 , both the first shielding member 3 and the second shielding member 4 are installed on the side of the curtain wall 2 away from the building. Both the first shielding member 3 and the second shielding member 4 extend along the height direction L of the building, and the first shielding member 3 and the second shielding member 4 intersect to form an angle. The first shielding member 3 and the second shielding member 4 respectively shield part of the curtain wall 2 so that the part of the curtain wall 2 within the angle is exposed and forms a triangular shape.

[0052] In some embodiments, in order to reduce the impact of the first shielding member 3 and the second shielding member 4 on the appearance of the building's outer facade, the cross-section of the first shielding member 3 and the second shielding member 4 along a direction perpendicular to the height direction L of the building can be rectangular or triangular.

[0053] In addition, Figure 4 shows a connection structure diagram of the first shielding member 3 and the second shielding member 4 of a curtain wall system. Referring to Figure 3 and Figure 4 , the intersecting first shielding member 3 and second shielding member 4 can form an "X" shape along the height direction L of the building on the outer facade of the building. The parts of the curtain wall 2 located in the two opposite acute-angle areas formed by the intersection of the first shielding member 3 and the second shielding member 4 are exposed and form a triangular shape.

[0054] Moreover, in order to improve the stability of the first shielding member 3 installed on the exterior facade of the building and reduce the possibility of deformation of the first shielding member 3 in the event of typhoons, storms or other weather conditions. Figure 5 shows Figure 3 the cross-sectional view in the D-D direction in, where A also represents the outside of the building and B also represents the inside of the building. Refer to Figure 5 , the first shielding member 3 includes a first side portion 301, a second side portion 302 and a third side portion 303. The first side portion 301, the second side portion 302 and the third side portion 303 are connected end to end in sequence to form a structure with a triangular cross-section, and the cross-section is a plane perpendicular to the curtain wall 2. Specifically, the cross-section can be an isosceles triangle structure, so that the first shielding member 3 has a certain force stability. The second side portion 302 faces the curtain wall 2 to shield a part of the curtain wall 2, and a straight line is formed at the intersection of the second side portion 302 and the curtain wall 2.

[0055] Continuing to refer to Figure 5 , the first side portion 301 includes a plurality of baffles 5 and a plurality of cross bars 6. The plurality of cross bars 6 are arranged at intervals along the height direction L of the building. The baffle 5 is connected to the cross bar 6, and the gap formed between every two adjacent cross bars 6 is shielded by the baffle 5.

[0056] In some embodiments, the cross bar 6 can be made of aluminum alloy profiles or stainless steel.

[0057] In addition, the baffle 5 can be made of aluminum single plates or stainless steel plates.

[0058] Among them, each baffle 5 can be welded between two adjacent cross bars 6, or screwed to the cross bar 6 through a galvanized angle steel. Specifically, the cross-section of the galvanized angle steel is L-shaped. One right-angled side of the galvanized angle steel is parallel to the baffle 5 and connected by self-tapping screws, and the other right-angled side is parallel to the cross bar 6 and connected by self-tapping screws.

[0059] Because the structures of the second side portion 302 and the first side portion 301 are the same, similarly, the second side portion 302 also includes a plurality of baffles 5 and a plurality of cross bars 6, which will not be elaborated here.

[0060] Continuing to refer to Figure 5 , the first shielding member 3 further includes a first vertical rod 304, a second vertical rod 305 and a third vertical rod 306. The first vertical rod 304, the second vertical rod 305 and the third vertical rod 306 are parallel to each other and arranged at intervals, and all extend along the height direction L of the building.

[0061] Moreover, the first vertical rod 304 and the third vertical rod 306 are closer to the curtain wall 2 relative to the second vertical rod 305. The first vertical rod 304, the second vertical rod 305, and the third vertical rod 306 are connected end to end to form an isosceles triangle. The first vertical rod 304, the second vertical rod 305, and multiple crossbars 6 and multiple baffles 5 connected between the first vertical rod 304 and the second vertical rod 305 form the first side portion 301.

[0062] Wherein, both ends of the crossbar 6 are respectively connected to the first vertical rod 304 and the second vertical rod 305, and the baffle 5 shields the gap formed between the first vertical rod 304 and the second vertical rod 305.

[0063] The second vertical rod 305, the third vertical rod 306, and multiple crossbars 6 and multiple baffles 5 connected between the second vertical rod 305 and the third vertical rod 306 form the second side portion 302.

[0064] Wherein, both ends of the crossbar 6 are respectively connected to the second vertical rod 305 and the third vertical rod 306, and the baffle 5 shields the gap formed between the second vertical rod 305 and the third vertical rod 306.

[0065] In addition, a third side portion 303 is formed between the first vertical rod 304 and the third vertical rod 306.

[0066] In some embodiments, the first vertical rod 304, the second vertical rod 305, and the third vertical rod 306 can be made of aluminum alloy profiles or stainless steel.

[0067] Specifically, both ends of the crossbar 6 of the first side portion 301 can be connected to the first vertical rod 304 and the second vertical rod 305 respectively by self-tapping screws, or can be welded to the first vertical rod 304 and the second vertical rod 305 respectively. Similarly, both ends of the crossbar 6 of the second side portion 302 can be connected to the second vertical rod 305 and the third vertical rod 306 respectively by self-tapping screws, or can be welded to the second vertical rod 305 and the third vertical rod 306 respectively.

[0068] Meanwhile, one end of the crossbar 6 of the first side portion 301 away from the first vertical rod 304 is connected to the second vertical rod 305, and one end of the crossbar 6 of the second side portion 302 away from the third vertical rod 306 is connected to the second vertical rod 305, effectively avoiding the ends of the crossbar 6 of the first side portion 301 and the ends of the crossbar 6 of the second side portion 302 being directly connected to form a gap, which is convenient for forming a folded angle of an isosceles triangle on the outer facade of the building.

[0069] In addition, Figure 6 shows Figure 5 an enlarged view of part F in Figure 5 and Figure 6, in order to facilitate the installation of outline lights or landscape lights on the outer facade of a building, so as to outline the building at night, lamp grooves 23 are formed along the extending direction of the first vertical rod 304 and along the extending direction of the third vertical rod 306. The outline lights or landscape lights can be respectively connected to the first vertical rod 304 and the second vertical rod 305 by screw connections through lighting connectors.

[0070] Figure 7 shows Figure 3 a cross-sectional view taken along the E-E direction in which A also represents the outside of the building and B also represents the inside of the building. Combining Figure 5 and Figure 7 , the column 1 includes a first column 101, a second column 102 and a third column 103, and all extend along the height direction L of the building. A cross beam 7 is connected between the first column 101 and the third column 103. Among them, third columns 103 are arranged on both sides of the first column 101, and the second column 102 is arranged between the first column 101 and the third column 103.

[0071] In some embodiments, the first column 101, the second column 102, the third column 103 and the cross beam 7 can all be made of aluminum alloy or stainless steel.

[0072] In addition, both the first column 101 and the third column 103 can be directly welded to the connecting steel plates pre-embedded in the building, and both the first column 101 and the third column 103 can also be directly bolted to the connecting steel plates pre-embedded in the building; both ends of the cross beam 7 can be respectively welded to the first column 101 and the third column 103 or connected by screws.

[0073] Among them, the second column 102 faces the cross beam 7 and is arranged opposite to the second vertical rod 305. The extending direction of the second column 102 is the same as the extending direction of the second vertical rod 305. The curtain wall 2 is installed in the gap formed between the first column 101 and the second column 102.

[0074] Specifically, an aluminum profile is connected to the end of the curtain wall 2. A card slot for clamping the end of the curtain wall 2 is arranged inside the aluminum profile. The end of the curtain wall 2 is clamped in the card slot, so that the curtain wall 2 is connected to the aluminum profile, and then sealant is injected into the card slot to reinforce the curtain wall 2 connected to the aluminum profile. Among them, the aluminum profile can be respectively connected to the first column 101 and the second column 102 by self-tapping screws, or directly welded to the first column 101 and the second column 102.

[0075] Moreover, a curtain wall 2 is also connected to the third column 103 along the direction away from the first column 101. The connection method of the curtain wall 2 on the third column 103 is the same as the connection method of the curtain wall 2 on the first column 101.

[0076] In addition, in order to enhance the facade effect of the building's exterior and also increase the area of the curtain wall 2 to facilitate the entry of light into the interior of the building, the first column 101 and the third column 103 can be arranged relatively farther away from the first shielding member 3 with respect to the second column 102. At the same time, the second columns 102 are provided on both sides of the first column 101, and curtain walls 2 are connected between the first column 101 and the two second columns 102 respectively, and a fold angle is formed between the two curtain walls 2 connected by the first column 101 respectively.

[0077] In some embodiments, the first column 101 includes a male column 1011 and a female column 1012, and the male column 1011 and the female column 1012 are spliced with each other to form the first column 101.

[0078] Continue to refer to Figure 7 , the first shielding member 3 and the second shielding member 4 are axisymmetric along the extending direction of the first column 101. Since the second shielding member 4 has the same structure as the first shielding member 3, the structure of the second shielding member 4 will not be elaborated in this application.

[0079] Continue to refer to Figure 5 , in order to facilitate ventilation towards the inner side of the building, a first ventilation duct 8 is formed between the second column 102 and the third column 103; a second ventilation duct 10 communicating with the first ventilation duct 8 is formed between the first vertical rod 304 and the third column 103, and the second ventilation duct 10 communicates with the outside of the building; a third ventilation duct 11 is formed between the first column 101 and the third column 103, and both ends of the third ventilation duct 11 communicate with the first ventilation duct 8 and the inner side of the building respectively.

[0080] Therefore, the flowing air outside the building can sequentially pass through the second ventilation duct 10, the first ventilation duct 8, and the third ventilation duct 11, thereby entering the inner side of the building to achieve indoor ventilation of the building.

[0081] Moreover, since a fold angle is formed between the two curtain walls 2 connected by the first column 101 respectively, the connection line between the first column 101 and the third column 103 is not parallel to the connection line between the first column 101 and the second column 102, reducing the area of the curtain wall 2 between the first column 101 and the second column 102 that shields the third ventilation duct 11, which is beneficial for the third ventilation duct 11 to ventilate towards the inner side of the building.

[0082] Refer to Figure 5 , in order to further increase the air intake volume of the first ventilation duct 8 and thus increase the air intake volume of the inner side of the building, a fourth ventilation duct 15 is formed between the third vertical rod 306 and the curtain wall 2, and both ends of the fourth ventilation duct 15 communicate with the first ventilation duct 8 and the outside of the building respectively, so that the flowing air outside the building can sequentially pass through the fourth ventilation duct 15, the first ventilation duct 8, and the third ventilation duct 11 to enter the inner side of the building.

[0083] Continue to refer to Figure 5 For the convenience of installing and fixing the first vertical rod 304, a first connecting rod 9 is connected to the third upright column 103, and one end of the first connecting rod 9 away from the third upright column 103 is connected to the first vertical rod 304.

[0094] In addition, to reduce the deflection of the second connecting rod 16 and improve the stability of the second connecting rod 16, the first connecting rod 9 is connected to the second connecting rod 16 through the third connecting rod 21.

[0095] In some embodiments, the third connecting rod 21 may be made of aluminum alloy or stainless steel.

[0096] Among them, both ends of the third connecting rod 21 can be welded to the first connecting rod 9 and the second connecting rod 16 respectively, or connected to the first connecting rod 9 and the second connecting rod 16 through galvanized angle steels respectively.

[0097] Moreover, to improve the installation stability of the second column 102, the third connecting rod 21 is connected to the second column 102 through the fourth connecting rod 22.

[0098] In some embodiments, the fourth connecting rod 22 may be made of aluminum alloy or stainless steel.

[0099] Wherein, both ends of the fourth connecting rod 22 can be welded to the third connecting rod 21 and the second upright post 102 respectively, or can be connected to the third connecting rod 21 and the second upright post 102 through galvanized angle steels respectively.

[0100] To facilitate the control of ventilation inside the building, with reference to Figure 8 , an opening fan 12 for blocking the third ventilation duct 11 is installed in the third ventilation duct 11. The opening fan 12 is connected to the first upright post 101. When the opening fan 12 is opened, both ends of the third ventilation duct 11 are respectively communicated with the first ventilation duct 8 and the inside of the building.

[0101] Specifically, the opening fan 12 includes a window sash 1201 and a window frame 1202. The window frame 1202 is respectively connected to the first upright post 101 and the third upright post 103. The opening fan 12 is used to block the communication between the first ventilation duct 8 and the inside of the building.

[0103] In some embodiments, the opening fan 12 can be set as a sliding window. A sliding groove for the window sash 1201 to slide is integrally formed in the window frame 1202. The window sash 1201 is slidably connected to the window frame 1202 through the sliding groove to realize the opening and closing of the opening fan 12 between the first upright post 101 and the third upright post 103.

[0104] In other embodiments, the opening fan 12 can be set as an inward-opening casement window. The window sash 1201 is rotatably connected to the window frame 1202. Specifically, the window sash 1201 is connected to the window frame 1202 through window hinges, and the rotation axis of the window sash 1201 is parallel to the height direction L of the building. Whether the window sash 1201 opens towards the inside or outside of the building, the window sash 1201 can be shielded by the curtain wall 2, the first shielding member 3 and the second shielding member 4 and not be exposed, so that the integrity of the outer facade of the building will not be damaged during the process of opening the window sash 1201.

[0105] In addition, for the convenience of the rotation and opening of the window sash 1201, a window handle is bolted or welded to the window sash 1201.
