[0031] The present invention will be further described in detail below in conjunction with embodiments and the accompanying drawings.

[0032] As Figures 1 to 4 shown, the connection structure of the convective ventilation type box body curtain wall of the present invention includes: a curtain wall column 1, a curtain wall crossbeam 2 connected to the curtain wall column 1, and one or more box bodies 3 installed on the outer sides of the curtain wall column 1 and the curtain wall crossbeam 2. The box body 3 further includes: a box body column 31, a box body crossbeam 32, a connecting rod 33, and a box body panel. Among them, on the left and right sides of the outside of each box body 3, there is provided one box body column 31 respectively. The top and bottom of each box body column 31 are respectively connected to the outer ends of a connecting rod 33, and the inner end of this connecting rod 33 is connected to the curtain wall column 1. The box body crossbeam 32 is connected between the connecting rods 33 on the left and right sides at the top of the box body 3 and between the connecting rods 33 on the left and right sides at the bottom of the box body 3. A hanging member 4 is fixedly connected to the curtain wall column 1, and an adjustable-height adapter 5 is installed on the hanging member 4. Through the hanging member 4 and the adapter 5, the curtain wall column 1 can be hung on a support 6 fixedly connected to a building load-bearing member.

[0033] In this embodiment, in order to achieve better lighting, energy-saving, and ventilation effects, the box body panel includes: perforated aluminum plates 341 installed on the left and right side surfaces of the box body 3 and laminated insulating LOW-E glass panels 343 installed on the outer surface of the box body 3. A heat-insulating aluminum plate opening window 342 is provided on the indoor side of the perforated aluminum plate 341. In this way, the relatively large outer surface of the box body 3 can be used for lighting, and the convective ventilation effect can be achieved through the perforated aluminum plates 341 on the left and right sides of the box body 3. At the same time, both the laminated insulating LOW-E glass panels 343 and the heat-insulating aluminum plate opening windows 342 have a certain heat-insulating effect, which is beneficial to the energy-saving of the building. In addition, as Figure 3 and Figure 4 shown, aluminum plates 36 are covered on the box body crossbeams 32 at the top and bottom of the box body 3.

[0034] In this embodiment, a plurality of the boxes 3 are provided and arranged horizontally and vertically. Preferably, two adjacent boxes 3 on the left and right are respectively a tapered box with a gradually increasing depth dimension from low to high and a tapered box with a gradually decreasing depth dimension from low to high. In this way, the adjacent boxes 3 have a staggered and convex outer shape, which can further enhance the effects of lighting and ventilation and add a sense of orderly beauty to the building. For the design of the depth dimension of the box, on the premise of meeting the requirements of the building for lighting, energy conservation, and ventilation, the length of the cantilever is optimized as much as possible to reduce the bending moment at the connection of the root of the cantilever. The maximum depth dimension of the box 3 does not exceed 450 mm.

[0035] To ensure the reliable force connection between the connecting rod 33 and the curtain wall column 1, as Figure 1 , Figure 5 and Figure 9 shown, the curtain wall column 1 is provided with a plug-in recess 11 at the connection with the connecting rod 33. The inner end of the connecting rod 33 is inserted into the plug-in recess 11 and fixed to the inner wall of the plug-in recess 11 with bolts. In this embodiment, the curtain wall column 1 is made of aluminum alloy profiles, and its horizontal cross-section is generally in the shape of a right-angled trapezoid. The plug-in recess 11 is provided at the front corner position and has a cross-section generally in the shape of a right-angled trapezoid. The connecting rod 33 is made of an aluminum alloy square tube structure. Correspondingly, the inner end of the connecting rod 33 is also cut into a right-angled trapezoid matching the plug-in recess 11. The length of the inner end of the connecting rod 33 inserted into the curtain wall column 1 is 50 mm to 80 mm, and in this embodiment, it is 65 mm. A U-shaped slot 12 also extends forward from the front of the curtain wall column 1, and the rear end of the perforated aluminum plate 341 is inserted into the U-shaped slot 12.

[0036] As Figure 10 shown, the box column 31 is made of aluminum alloy profiles, and the cross-section of its main body is square. A lateral extension plate 311 extends laterally outward from the front wall surface of the square cross-section, and a front extension plate 312 extends forward from the outer end of the lateral extension plate 311. The lateral extension plate 311 and the front extension plate 312 form an L shape. Among them, a connecting edge 313 protrudes from the back surface of the lateral extension plate 311, and two front and rear first hooks 314 protrude from the outer side surface of the front extension plate 312. As Figure 6 and Figure 7As shown, in order to strengthen the connection strength between the connecting rod 33 and the box column 31, the outer end of the connecting rod 33 is inserted into the square body of the box column 31 and fixedly connected to the side wall of the box column 31 with bolts. The length of the connecting rod 33 inserted into the box column 31 is 50 mm to 70 mm. The bent edge at the front end of the perforated aluminum plate 341 is fixedly connected to the connecting edge 313 of the box column 31 with screws. An L-shaped aluminum alloy outer cover 35 is buckled outside the front extension plate 312 and the end face of the laminated insulating LOW-E glass panel 343. Two second hooks 351 are convexly provided on the inner surface of the aluminum alloy outer cover 35, and the two second hooks 351 are respectively hooked with the two first hooks 314. The lateral extension plate 311, the front extension plate 312 and the aluminum alloy outer cover 35 enclose a U shape and surround the end of the laminated insulating LOW-E glass panel 343.

[0037] As Figure 3 and Figure 4 shown, at least two front and rear box cross beams 32 connected between the left and right connecting rods 33 are provided. In this embodiment, the box cross beam 32 is made of aluminum alloy profile, and the adjacent front and rear box cross beams 32 are nested and connected. Figure 11 What is shown is an exploded view of the front and rear box cross beams 32 at the bottom of the box 3 and the curtain wall cross beam 2. On the rear end faces of the front box cross beams 32, a first card slot 321 with a T-shaped cross section and a first L-shaped folded edge 322 protruding backward are respectively provided. At the position corresponding to the first card slot 321 at the front end of the rear box cross beam 32, a first card strip 323 with a T-shaped cross section is convexly provided. At the position corresponding to the first L-shaped folded edge 322, a recess 324 is provided and a first groove 325 is provided at the recess 324. The first card strip 323 is embedded in the first card slot 321, and the first L-shaped folded edge 322 is embedded in the recess 324 and the first groove 325 to form the nested connection of the adjacent front and rear box cross beams 32, thereby ensuring the high-precision installation of the product. In order to prevent rainwater leakage, the first L-shaped folded edge 322 is connected to the recess 324 of the rear box cross beam 32 with screws and sealant is applied at the recess 324. At the bottom of the box 3, the first card slot 321 and the first card strip 323 are provided at the upper position of the box cross beam 32, while the first L-shaped folded edge 322 and the recess 324 are provided at the lower position of the box cross beam 32. On the contrary, at the top of the box 3, the first card slot 321 and the first card strip 323 are provided at the lower position of the box cross beam 32, while the first L-shaped folded edge 322 and the recess 324 are provided at the upper position of the box cross beam 32.

[0038] In this embodiment, as Figure 8 and Figure 11As shown, the curtain wall cross beam 2 is made of aluminum alloy profile, and the last box cross beam 32 is nested and connected with the curtain wall cross beam 2. On the front end face of the curtain wall cross beam 2, there are respectively a second card slot 21 with a T-shaped cross section and a second L-shaped folding edge 22 protruding forward. At the position corresponding to the second card slot 21 at the rear end of the last box cross beam 32, there protrudes a second card strip 326 with a T-shaped cross section, and at the position corresponding to the second L-shaped folding edge 22, there is a second groove 327. The second card strip 326 is embedded in the second card slot 21, and the outer end folding edge of the second L-shaped folding edge 22 is embedded in the second groove 327 to form the nested connection between the box cross beam 32 and the curtain wall cross beam 2. And the second L-shaped folding edge 22 is connected to the rear end of the last box cross beam 32 by screws. Sealant is applied at the connection between the second L-shaped folding edge 22 and the second groove 327 for waterproofing. At the bottom of the box 3, the second card strip 326 is arranged at the upper part of the rear end of the box cross beam 32, and the second groove 327 is arranged at the bottom of the rear end of the box cross beam 32. On the contrary, at the top of the box 3, the second card strip 326 is arranged at the lower part of the rear end of the box cross beam 32, and the second groove 327 is arranged at the top of the rear end of the box cross beam 32. Thus, through the nested connection between the box cross beam 32 and the curtain wall cross beam 2, it can resist bending moment together with the connecting rod 33 inserted into the curtain wall column 1, providing a more reliable force-bearing connection.

[0039] To ensure that the curtain wall cross beam 2 has sufficient strength, as Figure 8 and Figure 11 shown, at the bottom position of the box 3 where the force is relatively large, a cross beam insert 23 is fixedly arranged in the front inner cavity of the curtain wall cross beam 2 where it is connected to the box cross beam 32.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
