Description

Technical Field

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

[0002] Curtain walls are very commonly used in large public buildings and high-end residential buildings due to their good permeability and generous and bright overall appearance.

[0003] Currently, opening fans are provided in the building exterior wall part of the curtain wall system. The opening fan is opened outwards and upwards by an opening hanging member provided at the top of the opening fan and a suspension shaft used in cooperation with the opening hanging member. After the opening fan is opened outwards towards the outside of the building exterior wall, the opening fan is located outside the building exterior wall.

[0004] When the opening fan is in the open state, the opening fan being located outside the building exterior wall will cause many problems. For example: 1. After the opening fan is opened outwards, it will affect the planar flatness of the building exterior wall and cannot ensure the integrity of the building exterior wall; 2. The opening fan is provided on the building exterior wall. After long-term use of the opening fan, the problem of aging of the hardware occurs, and the opening fan is prone to slight shaking, and the sealing performance and stability of the opening fan will be greatly reduced; 3. In the event of weather such as typhoons and storms, the wind force increases, the bearing capacity of the opening fan decreases, and problems such as deformation may occur. In severe cases, the opening fan may fall off, posing a serious threat to the personal safety of others. Summary of the Invention

[0005] An embodiment of this application provides a curtain wall system, the main purpose of which is to effectively avoid the exposure of the opening fan on the exterior of the building and improve the integrity of the building exterior wall.

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

[0007] A curtain wall system includes a first column, a second column, a curtain wall, an opening fan, and a ventilation member. The first column is used to be installed on the outside of the building. The second column is used to be installed on the outside of the building. An installation gap is formed between the second column and the first column. The curtain wall is installed on the first column. A first ventilation duct is formed between the curtain wall and the second column. The first ventilation duct is communicated with the installation gap. The opening fan is installed on the side of the curtain wall close to the building and is installed in the installation gap, and covers the installation gap. When the opening fan is opened, the opening fan is located inside the building, and the installation gap is communicated with the inside of the building. A ventilation cavity is formed inside the ventilation member. The ventilation member is installed on the side of the second column away from the building and covers the first ventilation duct. The first ventilation duct is communicated with the ventilation cavity. The ventilation member further forms a second ventilation duct. The two ends of the second ventilation duct are respectively communicated with the ventilation cavity and the outside of the building.

[0008] A curtain wall system provided by an embodiment of the present application. The curtain wall is installed on the first upright post to form the outer facade of a building. Since the opening sash is installed in the installation gap and on the side of the curtain wall close to the building, when the opening sash is opened, the opening sash is on the inner side of the outer facade of the building. Moreover, in order to achieve ventilation inside the building, a first ventilation duct is formed between the curtain wall and the second upright post. The opening sash can be exposed through the first ventilation duct. The curtain wall does not completely cover the opening sash and only blocks part of the opening sash. Also, since a ventilation member is installed on the side of the second upright post away from the building and covers the first ventilation duct, thus blocking the part of the opening sash not blocked by the curtain wall. Therefore, the opening of the opening sash does not damage the integrity of the building's outer facade, effectively avoiding the exposure of the opening sash on the outer facade of the building. In addition, when the opening sash is opened, the inside of the building, the installation gap, the first ventilation duct, the ventilation cavity, the second ventilation duct, and the outside of the building are connected in sequence, ensuring the indoor ventilation of the building.

[0009] In some possible embodiments of the present application, the opening sash is rotatably connected to the first upright post, and the rotation axis of the opening sash is parallel to the height direction of the building.

[0010] By rotatably connecting the opening sash to the first upright post, it is convenient to open and close the opening sash. In addition, the rotation axis of the opening sash is parallel to the height direction of the building, so that the opening sash does not require additional support after being opened.

[0011] In some possible embodiments of the present application, a heat insulation board is provided on the side of the opening sash close to the building.

[0012] By providing the heat insulation board, the heat insulation board can play roles such as heat preservation, heat insulation, and noise reduction for the building.

[0013] In some possible embodiments of the present application, the curtain wall system further includes a third upright post for being installed on the outside of the building. The first upright post, the second upright post, and the third upright post all extend along the height direction of the building. The third upright post is arranged between the first upright post and the second upright post. A cross beam is connected between the first upright post and the second upright post. The third upright post is opposite to the cross beam, and the third upright post is arranged closer to the ventilation member relative to the first upright post and the second upright post. The curtain wall is installed between the first upright post and the third upright post, and a first ventilation duct is formed between the second upright post and the third upright post.

[0014] The first column, the second column, and the third column all extend along the height direction of the building. Moreover, a first ventilation duct is formed between the second column and the third column, so the first ventilation duct also extends along the height direction of the building to achieve the effect of simultaneous air intake on each floor of the building. Then, through the cross beam, it is convenient to connect the first column and the second column. The third column is arranged closer to the ventilation component relative to the first column and the second column, and the curtain wall is installed between the first column and the third column to further fix the curtain wall. The connection line between the first column and the third column forms an angle with the connection line between the first column and the second column, so that the curtain wall and the opening fan form an angle. On the one hand, it increases the facade effect of the building's exterior, and on the other hand, it increases the installable area of the curtain wall, facilitating light to shine into the interior of the building.

[0015] In some possible embodiments of the present application, the ventilation component includes a first side portion, a second side portion, and a third side portion; the first side portion, the second side portion, and the third side portion are connected end to end in sequence, and a ventilation cavity is formed inside, and a structure with a triangular cross-section is formed; wherein, the cross-section is a plane perpendicular to the curtain wall; the opening of the angle formed by the first side portion and the second side portion faces the building, and the first side portion is opposite to the first ventilation duct, and the second side portion is opposite to the curtain wall; the first side portion is arranged at an interval from the second column, and a second ventilation duct is formed between the first side portion and the second column.

[0016] The cross-section of the ventilation component is a triangular structure. Because a triangle has certain force stability, when the ventilation component is installed outside the curtain wall, the possibility of deformation of the ventilation component is reduced in the event of typhoons or storms and other weather conditions; at the same time, the triangular structure can also increase the facade shape of the building's exterior, making the building's exterior more beautiful; in addition, the first side portion is opposite to the first ventilation duct, thereby blocking the first ventilation duct so that the first ventilation duct will not affect the shape of the building's exterior, and a second ventilation duct is formed between the first side portion and the second column, realizing air intake from the side of the ventilation component, and ensuring the ventilation inside the building without affecting the shape of the building's exterior.

[0017] In some possible embodiments of the present application, the second side portion is arranged at an interval relative to the curtain wall, and a third ventilation duct is formed between the second side portion and the curtain wall, and the third ventilation duct communicates the ventilation cavity and the outside of the building.

[0018] Through the third ventilation duct formed between the second side portion and the curtain wall, the air intake volume of the ventilation cavity is increased, thereby increasing the ventilation volume inside the building.

[0019] 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 blocked by the baffles.

[0020] The height of a building is usually relatively high, especially for high-rise buildings. By arranging multiple cross bars at intervals along the height direction of the building and connecting the baffles to the cross bars, the gaps formed between two adjacent cross bars are blocked, facilitating the formation of a first side portion and a second side portion on the high-rise building.

[0021] In some possible embodiments of the present application, the ventilation 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, and the second vertical rod is arranged relative to the third column; 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, and a second ventilation duct is formed between the first vertical rod and the second column; 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, and a third ventilation duct is formed between the third vertical rod and the curtain wall; a third side portion is formed between the first vertical rod and the third vertical rod.

[0022] The first vertical rod and the third vertical rod are closer to the curtain wall relative to the second vertical rod, such that the connection lines of the first vertical rod, the second vertical rod, and the third vertical rod form a triangle; then, 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, facilitating the connection of the end portion of the first side portion and the end portion of the second side portion; moreover, a second ventilation duct is formed between the first vertical rod and the second column, and a third ventilation duct is formed between the third vertical rod and the curtain wall, realizing air intake from the side of the ventilation member.

[0023] In some possible embodiments of the present application, the first vertical rod is connected with a first connecting rod, one end of the first connecting rod away from the first vertical rod is connected to the second column, a first ventilation plate is connected to the first connecting rod, the first ventilation plate covers the second ventilation duct, and the first ventilation plate is penetrated with multiple first ventilation holes, and the first ventilation holes communicate the ventilation cavity and the outside of the building.

[0024] By connecting the first connecting rod to the first vertical rod and the second column respectively, the fixation of the ventilation member is realized; by blocking the second ventilation duct with the first ventilation plate, on the one hand, the influence on the appearance of the building facade due to 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, and 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.

[0025] In some possible embodiments of the present application, a second connecting rod is connected to the curtain wall in the direction of the third vertical rod, a second ventilation plate is connected to the second connecting rod, the second ventilation plate covers the third ventilation duct, and a plurality of second ventilation holes are formed through the second ventilation plate, and the second ventilation holes communicate the ventilation cavity and the outside of the building.

[0026] Furthermore, the third ventilation duct is blocked by the second ventilation plate. On the one hand, the influence on the appearance of the building facade caused by the too large gap of the third ventilation duct is reduced. On the other hand, sundries are reduced from entering the third ventilation duct along with the air flow, and the flowing air outside the building enters the third ventilation duct through the second ventilation holes, without affecting the ventilation of the third ventilation duct.

[0039] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection" and "coupling" 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 a direct connection or an indirect connection 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 outer structural schematic diagram of a curtain wall system is shown, where Figure 1 A represents the outside of the building, and B represents the inside of the building. As Figure 1As shown in the figure, the building is provided with multiple floors along the height direction L of the building. Each floor includes a ceiling board 22 and a floor surface layer 23. The ceiling board 22 and the floor surface layer 23 of each floor are arranged from top to bottom, and an internal space of one floor is formed between the ceiling board 22 and the floor surface layer 23.

[0041] Figure 2 is Figure 1 the cross-sectional view in the C-C direction in, combined with Figure 1 and Figure 2 , in the curtain wall system, in order to achieve ventilation inside the floor, an opening sash 6 is provided. Since the opening sash 6 is directly arranged on the outer facade part of the building, after the opening sash 6 is opened towards the outside of the building, the opening sash 6 is outside the outer facade of the building, which will not only pose some safety hazards but also affect the aesthetics of the building.

[0042] In order to effectively avoid the exposure of the opening sash 6 on the outer facade of the building, the present application provides a curtain wall system, Figure 3 shows the front view of a partial structure of a curtain wall system, Figure 4 shows Figure 3 the cross-sectional view in the D-D direction in, where Figure 4 in, A also represents the outside of the building, and B also represents the inside of the building. Specifically, combined with Figure 3 and Figure 4 , the curtain wall system includes a first column 1, a second column 2, a curtain wall 4, an opening sash 6 and a ventilation member 7. The first column 1 and the second column 2 are both used to be installed on the outside of the building, and the outside of the building is the side of the building far from the interior. Moreover, the first column 1 and the second column 2 are arranged at intervals, and an installation gap 3 is formed between the first column 1 and the second column 2, and the installation gap 3 communicates with the inside of the building. The extending directions of the first column 1 and the second column 2 can have various situations. In the present application, the first column 1 and the second column 2 both extend along the height direction L of the building.

[0043] In some embodiments, both the first column 1 and the second column 2 can be made of aluminum alloy or stainless steel.

[0044] In addition, connection steel plates respectively used for connecting with the first column 1 and the second column 2 are embedded in the outer wall of the building. There are various situations for the connection methods between the first column 1 and the second column 2 and the connection steel plates of the building outer wall. By way of example, the first column 1 and the second column 2 can be directly welded to the connection steel plates respectively, or the first column 1 and the second column 2 can be bolted to the connection steel plates respectively.

[0045] Refer to Figure 4, the curtain wall 4 is installed on the first column 1. Specifically, the curtain wall 4 can be hollow tempered Low-E glass or transparent glass. Multiple curtain walls 4 can be laid side by side along the height direction L of the building on the first column 1, or laid side by side along a direction perpendicular to the height direction L of the building on the first column 1 to form the outer facade of the building.

[0046] In some embodiments, each curtain wall 4 can be trapezoidal or rectangular and satisfy a minimum cutting size of 300 mm.

[0047] Among them, the curtain wall 4 extends towards the second column 2 and forms a first ventilation duct 5 with the second column 2. The first ventilation duct 5 communicates with the installation gap 3.

[0048] Moreover, in order to further install and fix the curtain wall 4, the curtain wall system further includes a third column 11. The third column 11 also extends along the height direction L of the building, and the third column 11 is installed on the outside of the building. The third column 11 is arranged between the first column 1 and the second column 2, and the curtain wall 4 is installed between the first column 1 and the third column 11, and a first ventilation duct 5 is formed between the second column 2 and the third column 11.

[0049] Figure 5 Shows Figure 4 an enlarged view of part E in Figure 4 and Figure 5 , an aluminum profile 27 is connected to the end of the curtain wall 4. A clamping groove for clamping the end of the curtain wall 4 is provided inside the aluminum profile 27. The end of the curtain wall 4 is clamped in the clamping groove, so that the curtain wall 4 is connected to the aluminum profile 27, and then sealant is injected into the clamping groove to reinforce the curtain wall 4 connected to the aluminum profile 27.

[0050] Among them, the aluminum profile 27 can be respectively connected to the first column 1 and the third column 11 by screws, or directly welded to the first column 1 and the third column 11, so that the curtain wall 4 is installed between the first column 1 and the third column 11.

[0051] Furthermore, in order to reduce the gap between the curtain wall 4 and the aluminum profile 27 after the end of the curtain wall 4 is clamped in the clamping groove, a rubber strip is bonded between the curtain wall 4 and the aluminum profile 27. Specifically, the rubber strip can be an EPDM (ethylene-propylene) rubber strip.

[0052] In addition, in order to facilitate the first column 1 and the second column 2 to form an integral body, referring to Figure 4 , a cross beam 12 is connected between the first column 1 and the second column 2.

[0053] In some embodiments, the cross beam 12 can be made of aluminum alloy or stainless steel.

[0054] Therefore, both ends of the cross beam 12 can be welded to the first upright post 1 and the second upright post 2 respectively or connected by screws.

[0055] Continuing to refer to Figure 4 , in order to enhance the facade effect of the building's exterior and also increase the area of the curtain wall 4 to facilitate light penetration into the interior of the building, the third upright post 11 is opposite to the cross beam 12, and the third upright post 11 is arranged away from the building relative to the first upright post 1 and the second upright post 2.

[0056] Meanwhile, third upright posts 11 are arranged on both sides of the first upright post 1, curtain walls 4 are connected between the first upright post 1 and the two third upright posts 11 respectively, and a fold angle is formed between the two curtain walls 4 connected by the first upright post 1 respectively.

[0057] In some embodiments, the first upright post 1 includes a male upright post 101 and a female upright post 102, and the male upright post 101 and the female upright post 102 are spliced with each other to form the first upright post 1.

[0058] Figure 6 Shows Figure 4 an enlarged view of part F in Figure 4 and Figure 6 , in order to open and close the installation gap 3, an opening fan 6 is installed in the installation gap 3, and the opening fan 6 is installed on the side of the curtain wall 4 close to the building and blocks the installation gap 3. When the opening fan 6 is opened, the installation gap 3 communicates with the inner side of the building.

[0059] Specifically, the opening fan 6 includes a window sash 601 and a window frame 602, and the window frame 602 is connected to the first upright post 1 and the second upright post 2 respectively. The cross-section of the window frame 602 along the height direction L of the building can be rectangular, the window sash 601 is installed in the window frame 602, and the window sash 601 can be vacuum glass or tempered glass.

[0060] Among them, the window frame 602 can be made of stainless steel or aluminum alloy. One side of the window frame 602 along the height direction of the building is fixed to the first upright post 1 by self-tapping screws, and the other side is also fixed to the second upright post 2 by self-tapping screws.

[0061] In some embodiments, the opening fan 6 can be set as a sliding window. A sliding groove for the window sash 601 to slide is integrally formed in the window frame 602, and the window sash 601 is slidably connected to the window frame 602 through the sliding groove to realize the opening and closing of the opening fan 6 between the first upright post 1 and the second upright post 2. At the same time, because the opening fan 6 is located inside the building's exterior facade and is blocked by the curtain wall 4, the opening fan 6 can be effectively prevented from being exposed on the building's exterior facade.

[0062] In some other embodiments, the opening sash 6 can be set as an inward-opening casement window, and the sash 601 is rotatably connected to the window frame 602. Specifically, the sash 601 is connected to the window frame 602 through a window hinge, and the rotation axis of the sash 601 is parallel to the height direction L of the building, and the sash 601 opens towards the inner side of the building. At the same time, since the opening sash 6 opens towards the inner side of the building and is blocked by the curtain wall 4, the opening sash 6 can be effectively prevented from being exposed on the outer facade of the building.

[0063] In addition, in order to facilitate the rotation and opening of the sash 601, a window handle is bolted or welded to the sash 601.

[0064] Moreover, in order to play a role in heat preservation and insulation for the internal space of the building, a heat insulation board 10 is provided on the side of the opening sash 6 close to the building.

[0065] In some embodiments, the heat insulation board 10 can be polyurethane foam or polystyrene board.

[0066] In addition, since a first ventilation duct 5 is formed between the curtain wall 4 and the second column 2, the opening sash 6 can be exposed through the first ventilation duct 5. The curtain wall 4 does not completely cover the opening sash 6, and the curtain wall 4 only plays a role in blocking part of the opening sash 6. In order to block the part of the opening sash 6 not blocked by the curtain wall 4, refer to Figure 4 , a ventilation member 7 is installed on the side of the second column 2 away from the building and covers the first ventilation duct 5. A ventilation cavity 8 is formed inside the ventilation member 7, the first ventilation duct 5 is communicated with the ventilation cavity 8, and the ventilation member 7 further forms a second ventilation duct 9, and both ends of the second ventilation duct 9 are communicated with the ventilation cavity 8 and the outside of the building respectively.

[0067] In some embodiments, in order to reduce the appearance impact of the ventilation member 7 on the outer facade of the building, the cross-section of the ventilation member 7 along the direction perpendicular to the height direction L of the building can be rectangular or triangular.

[0068] Moreover, in order to improve the stability of the ventilation member 7 installed on the outer facade of the building and reduce the possibility of deformation of the ventilation member 7 in the event of typhoons, storms or other weather conditions. Figure 7 Shows Figure 4 Part of the structural diagram in, where Figure 7 A in also represents the outside of the building, and B also represents the inside of the building. Refer to Figure 7 , the ventilation member 7 includes a first side portion 701, a second side portion 702 and a third side portion 703. The first side portion 701, the second side portion 702 and the third side portion 703 are connected end to end in sequence, and a ventilation cavity 8 is formed inside, and a structure with a triangular cross-section is formed, where the cross-section is a plane perpendicular to the curtain wall 4. And, the opening of the fold angle formed by the first side portion 701 and the second side portion 702 faces the building, and the first side portion 701 faces the first ventilation duct 5.

[0069] Specifically, the cross-section can be an isosceles triangle structure, so that the ventilation member 7 has a certain force stability.

[0070] Referring to Figure 7 , the first side portion 701 includes a plurality of baffles 20 and a plurality of cross bars 21. The plurality of cross bars 21 are arranged at intervals along the height direction L of the building. The baffles 20 are connected to the cross bars 21, and the gaps formed between every two adjacent cross bars 21 are blocked by the baffles 20.

[0071] In some embodiments, the cross bar 21 can be made of aluminum alloy profile or stainless steel.

[0072] In addition, the baffle 20 can be made of aluminum single plate or stainless steel plate.

[0073] Among them, each baffle 20 can be welded between two adjacent cross bars 21, or screwed to the cross bar 21 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 20 and connected by self-tapping screws, and the other right-angled side is parallel to the cross bar 21 and connected by self-tapping screws.

[0074] Because the structure of the second side portion 702 is the same as that of the first side portion 701, similarly, the second side portion 702 also includes a plurality of baffles 20 and a plurality of cross bars 21, and the specific structure of the second side portion 702 will not be elaborated here.

[0075] Continuing to refer to Figure 7 , the ventilation member 7 further includes a first vertical bar 704, a second vertical bar 705 and a third vertical bar 706. The first vertical bar 704, the second vertical bar 705 and the third vertical bar 706 are parallel to each other and arranged at intervals, and all extend along the height direction L of the building. The second vertical bar 705 is arranged opposite to the third column 11.

[0076] Moreover, the first vertical bar 704 and the third vertical bar 706 are closer to the curtain wall 4 relative to the second vertical bar 705. The first vertical bar 704, the second vertical bar 705 and the third vertical bar 706 are connected end to end to form an isosceles triangle. The first vertical bar 704 and the second vertical bar 705, and a plurality of cross bars 21 and a plurality of baffles 20 connected between the first vertical bar 704 and the second vertical bar 705 form the first side portion 701.

[0077] Among them, both ends of the cross bar 21 are respectively connected to the first vertical bar 704 and the second vertical bar 705, and the baffle 20 blocks the gap formed between the first vertical bar 704 and the second vertical bar 705.

[0078] The second vertical bar 705 and the third vertical bar 706, and a plurality of cross bars 21 and a plurality of baffles 20 connected between the second vertical bar 705 and the third vertical bar 706 form the second side portion 702.
