[0053] Figure 1 For a partial structural diagram of a metal curtain wall provided in an embodiment of the utility model, please refer to Figure 1 .

[0054] This embodiment provides a metal curtain wall, which includes a plurality of metal sandwich decorative panels 20 arranged in sequence and connected to each other, a window located between at least one metal sandwich decorative panel 20, the inner side of which is connected to the interior of the house and the outer side of which is connected to the outside, and a window frame edge trimming system 10 located between the window frame and the metal sandwich decorative panel 20, wherein both ends of the window frame edge trimming system 10 are respectively sealed and connected to the corresponding window frame 30 or the side of the metal sandwich decorative panel 20 to ensure the sealing of the metal curtain wall. The metal sandwich decorative panels 20 arranged in sequence are all arranged on the purlin keel to ensure the stability of the metal curtain wall, and the windows can allow sunlight from the outside to shine into the house, increase the brightness and permeability of the house, and reduce the sense of oppression. And the windows can be opened for ventilation. Since the material of the window frame 30 is different from that of the metal sandwich decorative panel 20, when the temperature changes for a long time and the thermal expansion and contraction occur, the deformation of the two is different, so there will be a deformation difference. If the connection point between the window frame 30 and the metal sandwich decorative panel 20 is fixed, it is very easy to be affected by the deformation difference and produce a gap, affecting the sealing of the metal curtain wall. The length of the window frame edge trimming system 10 of this embodiment is variable, so that the deformation difference at both ends can be absorbed without affecting the connection strength and sealing of the ends.

[0055] Since the metal sandwich decorative panel 20 and the window are both visible parts, the aesthetics of the appearance needs to be considered when installing the window on the metal curtain wall. Figure 1 In some achievable embodiments of the present invention, in terms of appearance, the width of the window frame edge trimming system 10 is uniformly arranged around the outer periphery of the window frame 30, and there is a uniform spacing H between the window frame edge trimming system 10 and the metal sandwich decorative panel 20 on the outer periphery, and the outer side surface of the window frame edge trimming system 10 is flush with the outer surface of the metal sandwich decorative panel 20. The spacing between the adjacent edges of two adjacent metal sandwich decorative panels 20 is also H. The spacing H can not only accommodate assembly errors, but also make the entire metal curtain wall have uniformly distributed horizontal lines and vertical lines formed by the above spacing H, making the entire metal curtain wall more beautiful. As an optional solution, H is 20mm. Of course, in other embodiments, H can also be 10mm, 15mm or 25mm, as long as the modeling requirements are met, and this embodiment does not make specific limitations on this.

[0056] In order to facilitate the installation between adjacent metal sandwich decorative panels 20 and ensure the reliability of the connection, the ends of the metal sandwich decorative panels 20 have interfaces, specifically, one side has a male interface 22, and the other side has a female interface 21. The male interface 22 of the downstream metal sandwich decorative panel 20 is plugged into the female interface 21 of the upstream metal sandwich decorative panel 20 to achieve the positioning and sealing connection of the two adjacent metal sandwich decorative panels 20. Since the interface along one direction, such as the horizontal interface, can achieve the positioning of the metal sandwich decorative panel 20, the longitudinal sides of the metal sandwich decorative panel 20 may not be provided with interfaces, and only the side surfaces of the vertical wall are sufficient. Therefore, the structure of the window frame trimming system 10 at each side of the window frame is different.

[0057] Specifically, in some achievable embodiments of the present invention, the window frame trimming system 10 includes an upper trimming piece 100 located on the upper side of the window frame 30, a lower trimming assembly 200 located on the lower side of the window frame 30, a left trimming piece 300 located on the left side of the window frame 30, and a right trimming assembly 400 located on the right side of the window frame 30, to correspond to the different structures around the window frame 30.

[0058] Figure 2 for Figure 1 The cross-sectional view at AA in the middle, then combined with Figure 1 and Figure 2 The upper edge trimming member 100 will be described in detail.

[0059] Please refer to Figure 2In some embodiments of the present invention, a structure of the upper edge trimming member 100 that can be realized is that one end of the upper edge trimming member 100 is located between the upper side of the window frame 30 and the purlin keel, and the screws pass through the window frame 30 and one end of the upper edge trimming member in sequence and are screwed on the purlin keel to lock the end of the upper edge trimming member and the upper side of the window frame 30 on the purlin keel. The other end of the upper edge trimming member 100 is located between the metal sandwich decorative panel 20 and the purlin keel, and the screws pass through the metal sandwich decorative panel 20 and the other end of the upper edge trimming member 100 in sequence and are screwed on the purlin keel to lock the metal sandwich decorative panel 20 and the other end of the upper edge trimming member 100 on the purlin keel. In this way, the stability of the installation of the upper edge trimming member 100 is ensured. In addition, since there is sealant between the ends of the upper edge trimming member 100 and the corresponding purlin keel and the window frame 30 or the metal sandwich decorative panel 20, the sealing is ensured. The upper trimming piece 100 has a boss 110 in the center that is flush with the outer surface of the metal sandwich decorative panel 20, and there is a spacing H between the upper end of the outer side of the boss 110 and the lower side of the metal sandwich decorative panel 20. It can be understood that, for the sake of modeling requirements, the appearance of the metal curtain wall here only needs to look like there is a gap, so as an optional solution, the upper side of the boss 110 is recessed toward the inner side to form a concave platform 120, and the width of the concave platform 120 in the vertical direction is H. The part of the upper trimming piece 100 between the inner side of the concave platform 120 and the purlin keel is fitted and abutted against the lower side of the metal sandwich decorative panel 20, and as an option, there is adhesive between the part of the upper trimming piece 100 between the inner side of the concave platform 120 and the purlin keel and the lower side of the metal sandwich decorative panel 20. When the metal sandwich decorative panel 20 and the window frame 30 are affected by the external temperature and expand and contract, but a difference occurs due to the different amounts of expansion and contraction, the boss 110 can be expanded to eliminate the error, thereby achieving variable length of the upper edge piece 100.

[0060] When it rains or snows, rainwater will flow inward along the top of the window, causing the phenomenon of urine eaves and contaminating the window, affecting the transparency of the window. Figure 2 As an optional solution, the lower end of the boss 110 protrudes downward from the upper side of the window frame 30 and has a water collection structure 130, and the upper edge trimming piece 100 between the water collection structure 130 and the window frame 30 is flush with the upper side of the window frame 30. When rainwater flows down along the metal curtain wall and flows to the outer surface of the boss 110, it will flow inward along the boss 110 and finally gather at the lower side of the water collection structure 130. Due to the effect of gravity, the rainwater will stop at the lower side of the water collection structure 130 and fall down. There is a certain distance between the water collection structure 130 and the window, so that the phenomenon of urine eaves will not appear at the upper eaves of the window.

[0061] Figure 3 for Figure 1 The cross-sectional view at the middle BB, then combined with Figure 3The lower edge trimming assembly 200 is described in detail.

[0062] In some achievable embodiments of the present invention, the lower edge trimming assembly 200 is located between the lower side of the window frame 30 and the upper side of the metal sandwich decorative panel 20, and there is a spacing H between the lower end of the outer side of the lower edge trimming assembly 200 and the upper end of the outer surface of the metal sandwich decorative panel 20, thereby ensuring the aesthetic appearance of the metal curtain wall. The lower edge trimming assembly 200 is provided with a water guide structure 2111, and the inner side of the water guide structure 2111 abuts against the outer end of the lower side of the window frame 30. The water guide structure 2111 can guide rainwater or liquid to flow outward and slide along the metal sandwich decorative panel 20, thereby preventing liquid from gathering at the lower eaves of the window frame 30 and reducing the risk of liquid leakage in the house.

[0063] Specifically, a structure that can be realized for the lower edge trimming assembly 200 is that the lower edge trimming assembly 200 includes a lower edge trimming piece 210 and a waterproof seal 220, wherein one end of the lower edge trimming piece 210 is located between the lower side of the window frame 30 and the purlin keel, and screws are sequentially passed through the lower side of the window frame 30 and the end of the lower edge trimming piece 210 and screwed on the purlin keel to lock the window frame 30 and the lower edge trimming piece 210 on the purlin keel, and the other end is connected to the purlin keel above the metal sandwich decorative panel 20, and the screws are sequentially passed through the metal sandwich decorative panel 20 and the other end of the lower edge trimming piece 210 and screwed on the purlin keel. Screwed on the purlin keel to lock the other end of the lower edge trim 210 and the metal sandwich decorative panel 20 on the purlin keel, the other end of the lower edge trim 210 abuts against the inner side of the upper side of the metal sandwich decorative panel 20, and the center of the lower edge trim 210 has a lower protrusion 211 flush with the outer surface of the metal sandwich decorative panel 20. When there is a displacement difference at the connection between the metal sandwich decorative panel 20 and the window frame 30, the lower protrusion 211 can be unfolded to eliminate the displacement difference, thereby realizing the variable length of the lower edge trim 210 and ensuring the reliability of the connection points at both ends of the lower edge trim 210. The part between the lower protrusion 211 and the window frame 30 is inclined toward the outside to form a water guide structure 2111, which has the function of guiding the flow of liquid. There is a lower edge 2113 parallel to the upper side of the metal sandwich decorative panel 20 between the lower protrusion 211 and the purlin keel, and a spacing H is provided between the lower edge 2113 and the metal sandwich decorative panel 20, so that the spacing between the lower protrusion 211 and the metal sandwich panel is uniform, and the waterproof seal 220 is located between the upper side of the metal sandwich decorative panel 20 and the lower edge 2113, and the outer end of the waterproof seal 220 is located on the inner side of the outer side of the lower edge member 210. Therefore, the waterproof seal 220 cannot be seen on the outside of the metal curtain wall, which ensures the beautiful appearance of the metal curtain wall while preventing water and other liquids from entering from the spacing, avoiding leakage of the metal curtain wall, and ensuring the sealing.

[0064] It can be understood that in order to ensure that the deformation difference between the window frame 30 and the metal sandwich decorative panel 20 can be eliminated, the upper edge trimming member 100 and the lower edge trimming member 210 have a certain deformation capacity, and the stronger the deformation capacity, the weaker the rigidity. Therefore, it is easy to be deformed by the influence of external objects or its own gravity, especially the lower edge trimming member 210. For this reason, as an optional scheme, the lower edge trimming assembly 200 also includes a lower support member 230, and the lower support member 230 is located in the lower protrusion 211. The lower support member 230 is respectively abutted against the inner side of the lower edge 2113, the purlin keel and the inner side of the water guide structure 2111, and is connected to the purlin keel by screws. The outer end of the lower support member 230 is parallel to the outer side surface of the lower edge trimming member 210 and has a certain distance. While supporting the lower protrusion 211 and increasing the strength of the lower edge trimming member 210, it does not affect the change in the length of the lower edge trimming member 210.

[0065] Figure 4 for Figure 1 The cross-sectional view at CC in the middle, then combined with Figure 4 The left edge trimming piece 300 will be described in detail.

[0066] In some embodiments of the utility model, a possible structure of the left edge trimming piece 300 is that the left end of the left edge trimming piece 300 is connected to the concave platform 120 outside the male interface 22 on the right side of the metal sandwich decorative panel 20 by screws. The right end abuts against the right end surface of the male interface 22 and extends between the window frame 30 and the purlin keel, and the left frame of the window frame 30 and the end of the left edge trimming piece 300 are locked on the purlin keel by screws to ensure the reliability of the fixation of the end of the left edge trimming piece 300. The male interface 22 can play a supporting role for the left edge trimming piece 300, thereby ensuring that the left edge trimming piece 300 will not be deformed by external objects. The left edge trimming piece 300 has a left protrusion 310 in the center that is flush with the outer side surface of the metal sandwich decorative panel 20. The left protrusion 310 can be flattened to eliminate the displacement difference between the metal sandwich decorative panel 20 and the window frame 30 due to the different amounts of thermal expansion and contraction. A groove is provided between the right side of the left protrusion 310 and the outer metal plate of the metal sandwich decorative panel 20. The screw is located in the groove to fix the left end of the left edge trimming piece 300 to the male interface 22. The width of the groove in the left and right directions is H, which ensures the aesthetic appearance of the metal curtain wall.

[0067] Figure 5 for Figure 1 The cross-sectional view at DD in the middle, then combined with Figure 5 The right edge finishing component 400 is described in detail.

[0068] In some achievable embodiments of the utility model, the right end of the right edge trimming component 410 can fill the female connector 21 on the left side of the metal sandwich decorative panel 20, and the left end of the right edge trimming component 410 abuts against the right side of the window frame 30, so that the female connector 21 does not need to be cut off from the metal sandwich decorative panel 20 to achieve connection with the window frame 30, saving time and effort. There is a distance H between the right side of the outer side of the right edge trimming component 400 and the left side of the outer surface of the metal sandwich decorative panel 20. The aesthetic appearance of the metal curtain wall is ensured.

[0069] Specifically, one possible structure of the right edge trimming component 400 is that the right edge trimming component 400 includes a blocking piece 420, a right edge trimming component 410, and an inner support piece 430, wherein the blocking piece 420 is located at the opening inside the female interface 21, one end of the blocking piece 420 is connected to the purlin keel by screws, and the other end is connected to the inner wall of the female interface 21 by adhesive to block the opening, that is, the blocking piece 420 is C-shaped. The right end of the right edge trimming component 410 is connected to the purlin keel on the left side of the blocking piece 420 by screws, the left end of the right edge trimming component 410 is located between the right side of the window frame 30 and the purlin keel, and the left end of the right edge trimming component 410 and the right side of the window frame 30 are fixed to the purlin keel by bolts to ensure the stable installation of the right edge trimming component 410. The right edge trimming piece 410 has a right protrusion 411 in the center, and the right protrusion 411 can be flattened to eliminate the deformation difference between the metal sandwich decorative panel 20 and the window frame 30 due to thermal expansion and contraction. The inner support piece 430 is located on the inner side of the right protrusion 411, and the inner support piece 430 is in contact with the right inner wall of the right protrusion 411, the purlin keel and the left inner wall of the right protrusion 411 in sequence. In order to ensure that the right edge trimming piece 410 can eliminate the deformation difference in time, the right edge trimming piece 410 has a certain deformation ability, and the corresponding right edge trimming piece 410 has weak rigidity, and the inner support piece can support the right protrusion 411 and will not be deformed by the outside influence. The outer side of the inner support piece 430 is parallel to the outer side surface of the right protrusion 411 and has a certain distance, so that the inner support piece 430 will not affect the flattening of the right protrusion 411 to eliminate the deformation difference.

[0070] Furthermore, the right protrusion 411 is flush with the outer surface of the metal sandwich decorative panel 20, and the right side of the right protrusion 411 is parallel to the blocking piece 420, and has a spacing H, thereby ensuring the aesthetic appearance of the metal curtain wall. In order to prevent rainwater and other liquids from entering the inner side of the metal sandwich decorative panel 20 from the spacing H and ensure the sealing and waterproof performance of the metal curtain wall, as an optional solution, a waterproof sealing piece 220 is provided at the spacing H, which not only plays a waterproof and sealing role, but also can be bonded to the right edge trimming piece 410 and the blocking piece 420 respectively to ensure the connection between the right edge trimming piece 410 and the blocking piece 420.

[0071] As an optional solution, the waterproof seal 220 is an EPDM rubber strip, which is low-cost and easy to assemble, and the right side edge of the right protrusion 411 is parallel to the sealing piece 420 so that the EPDM rubber strip can be applied more evenly during gluing, ensuring that the bonding area between the right edge piece 410 and the sealing piece 420 is uniform.

[0072] When the EPDM rubber strip is applied, the EPDM rubber strip will have a certain abutting force on the right edge trimming piece 410 and the sealing piece 420 respectively. The inner support piece 430 can ensure that the right protrusion 411 is not deformed.
