Description

Technical Field

[0001] This invention belongs to the field of building curtain wall technology, and in particular to a prefabricated inclined triangular folding irregular aluminum panel molding system. Background Technology

[0002] Aluminum panel decorative designs are widely used on building facades due to their high metallic luster, attractive appearance, and the ability to create various irregular shapes through panel splicing, meeting architects' needs for facade design while also providing sun shading. However, large-scale application of prefabricated inclined triangular folding aluminum panel systems on building facades is currently lacking, especially when the facade is tall and the overall transparency of the curtain wall system must be maintained. For large-span prefabricated inclined triangular folding aluminum panels protruding from the facade, traditional techniques often involve arranging numerous internal joists to enhance the rigidity of the panel design. With many fixing points, on-site installation of these joists would significantly increase the workload. Therefore, reducing on-site installation work while ensuring the decorative strip's shape, safety, reliability, and system sealing performance to prevent upward lifting under wind loads remains a challenge.

[0028] The structure of the present invention and the desired technical effects will be described below with reference to specific embodiments and accompanying drawings. However, the selected embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0029] like Figure 1 As shown, the present invention provides an assembled inclined triangular folding irregular aluminum plate molding system, including a keel structure 1, several aluminum plate structures 2 and a connecting structure 3 located between the two.

[0030] like Figure 2 , Figure 3As shown, the keel structure 1 is located on the exterior side of the building and includes several vertical supporting brackets (not shown in the figure, representing existing structures), each corresponding to the building's transverse span. Several transverse keels 11 are provided between adjacent supporting brackets; in this embodiment, square tubing is used. Preferably, to achieve a slender cross-section for the large-span transverse keels 11, adjacent transverse keels 11 are connected by vertical hangers 12. Threaded sleeves 13 are provided on the top and bottom surfaces of the transverse keels 11 to connect the hangers 12. The uppermost hanger 12 connects to the steel beam at the top of the building, and the lowermost hanger 12 connects to the steel beam at the bottom of the building. The hanger + horizontal large-span transverse keel support system effectively addresses the requirements of structural stress and architectural aesthetics, with the hangers 12 effectively transferring vertical loads from bottom to top to the upper main structural beams. The hanger rod 12 effectively controls the vertical deformation of the large-span transverse keel 11. The large-span transverse keel 11 only needs to resist horizontal loads, allowing its vertical cross-section to be very small. The horizontal dimension is determined by its span and the magnitude of the horizontal load. The flat shape of the transverse keel 11 cross-section effectively achieves a slender architectural aesthetic. The threaded sleeve 13 is fixed to the large-span transverse keel 11 with a locking washer. A through hole is opened on the keel corresponding to the threaded sleeve 13, with a diameter larger than that of the threaded sleeve 13. This serves two purposes: firstly, to absorb any deviation in the hole's diameter, and secondly, to effectively mitigate the problem of the hanger rod 12 bending due to horizontal deformation of the large-span transverse keel 11. A vertical elongated hole is opened on the connecting ear plate at the bottom of the hanger rod 12 to accommodate vertical deformation of the upper main structural beams and prevent the hanger rod 12 from failing under pressure. The horizontal, large-span transverse keel 11 resists horizontal loads, and the large through-hole structure on the transverse keel 11 at the corresponding threaded sleeve 13 position of the hanger 12 effectively alleviates the bending problem of the hanger 12. The hanger 12 is installed from top to bottom, relying on the hanger 12 to suspend the horizontal, large-span transverse keel 11 and control vertical deformation. The hanger + steel keel support steel structure system has reasonable stress distribution, is safe and reliable, is easy to install, and has a transparent architectural effect.

[0031] like Figure 4 , Figure 9As shown, the aluminum plate structure 2 is located on the outdoor side of the keel structure 1, including an upper crossbeam 21 and a lower crossbeam 22, which are fixedly connected at both ends by columns 23 to form a rectangular frame. The connection method of the upper crossbeam 21, the lower crossbeam 22 and the columns 23 can be as follows: the bottom surface of the upper crossbeam 21 and the top surface of the lower crossbeam 22 are each provided with U-shaped grooves 24 with opposite openings, and the two ends of the columns 23 are located in the corresponding U-shaped grooves 24 and are fixedly connected by mounting bolts 241. The top of the outer side of the rectangular frame is provided with an upper aluminum plate 25 that extends downwards towards the outdoor side, and the bottom of the outer side of the rectangular frame is provided with a lower aluminum plate 26 that extends upwards towards the outdoor side. The ends of the upper aluminum plate 25 and the lower aluminum plate 26 are welded together to form an integral panel, which is curved and has a triangular longitudinal section. The sides of the upper aluminum plate 25 and the lower aluminum plate 26 are each fixedly welded by a sealing plate 27, and the inner end of the sealing plate 27 is fixedly connected to the corresponding column 23.

[0032] The upper aluminum plate 25 and lower aluminum plate 26 of this invention can be made of ordinary aluminum plates, perforated aluminum plates, stainless steel plates, or other metal plates. The upper aluminum plate 25 and lower aluminum plate 26 are twisted shapes. After the upper and lower hyperbolic aluminum plates are twisted and formed, they are welded and spliced ​​along the joints of the upper and lower aluminum plates, then polished. The sealing plates 27 on both sides are welded to the upper aluminum plate 25 and lower aluminum plate 26 to form the triangular folded aluminum plate structure. Since the upper aluminum plate 25, lower aluminum plate 26, and sealing plates 27 form a whole, the aluminum plates support each other, forming a strong rigidity to resist external loads. This triangular folded aluminum plate structure does not require a keel for support to achieve a large span. On the facade, this folded triangular aluminum plate structure can also be made into an inclined shape to enrich the building facade.

[0033] like Figure 3 , Figure 5 , Figure 6 , Figure 9 As shown, the column 23 has a first vertical groove 231 with a T-shaped cross-section on the side facing the keel structure 1. A hanger 28 is provided at the top and bottom of the first vertical groove 231. The hanger 28 includes a first body 281 with a T-shaped cross-section, which is located within the first vertical groove 231 and fixedly connected to the column by a first fixing bolt 232. The end of the first body 281 extends outward from the first vertical groove 231, and a second body 282 with an L-shaped cross-section is provided. The bottom of the second body 282 has an upwardly recessed notch, forming a hook 283.

[0034] like Figure 2 , Figure 3 , Figure 7As shown, the transition structure 3 includes several vertical square tubes 31 located at the vertical joints between adjacent aluminum plate structures 2. Several horizontal square tubes 32 are provided between adjacent vertical square tubes 31, each horizontal square tube 32 corresponding to a horizontal keel 11 and corresponding to the horizontal joint of the adjacent aluminum plate structure 2. Figure 8 As shown, the connection between the vertical square tube 31 and the horizontal square tube 32 can be as follows: the side of the vertical square tube 31 is provided with a square tube connecting plate 33, the square tube connecting plate 33 includes a square tube vertical plate 331, the outer side of the square tube vertical plate 331 is provided with two parallel square tube horizontal plates 332, the end of the horizontal square tube 32 is located between the two square tube horizontal plates 332, and is fixedly connected by square tube bolts 333.

[0035] The vertical square tube 31 has a first adapter 34 on the side facing the horizontal keel 11, and a second adapter 35 on the side facing the aluminum plate structure 2. The first adapter 34 has a Π-shaped cross-section and includes a first fixing plate 341 and two first side plates 342 perpendicularly connected to the first fixing plate 341. The first fixing plate 341 is fixedly connected to the outdoor side of the horizontal keel 11 by a second fixing bolt 343 passing through the vertical square tube 31. The vertical square tube 31 is located between the two first side plates 342 and is fixedly connected by a third fixing bolt 344 (which can simultaneously fix the square tube connecting plate 33). The second adapter 35 includes a first plate 351 with a U-shaped cross-section, which surrounds the outside of the vertical square tube 31 and is connected by a first fixing screw 311. The first plate 351 has a second plate 352 with an H-shaped cross-section on its outer side, and the second plate 352 has a second vertical groove 353 with a T-shaped cross-section on its outer side. A third adapter 36 is provided within the second vertical groove 353 at a position corresponding to each hanger 28. The third adapter 36 includes a third plate 361 with a T-shaped cross-section, which is located within the second vertical groove 353 and fixedly connected to the second adapter 35 by a second fixing screw 362. The end of the third plate 361 is located outside the second vertical groove 353 and extends outward to form a fourth plate 363 with a square-ring cross-section. Figure 3 , Figure 9 As shown, in two adjacent aluminum plate structures 2, the adjacent hooks 283 are attached to the same fourth plate 363. The inclined variable cross-section triangular folded aluminum plate structure achieves three-dimensional adjustability through a series of hanging parts and transition systems, ensuring the precision of the building facade. Factory assembly fully leverages the advantages of high precision and ease of operation of factory production. After assembly, it is transported to the site, requiring only hoisting and hanging for fixation, greatly saving on-site installation workload and reducing on-site installation difficulty, thus achieving prefabricated installation.

[0036] When the span of the triangular folding aluminum panel is large, more mounting points need to be arranged along the span direction. Since the installation of large-span inclined triangular folding aluminum panels uses a hook-and-loop method, the upward movement of the triangular folding aluminum panel must be considered when wind loads act on the aluminum panel surface. Therefore, fixing measures must be taken at the top of the folding aluminum panel to ensure that the folding aluminum panel will not detach from the hooks under upward loads. In this invention, as... Figure 2 , Figure 9 , Figure 10 As shown, the upper crossbeam 21 has a T-shaped longitudinal groove 211 on the side facing the keel structure 1, and a positioning member 29 is provided in the groove 211. The positioning member 29 includes a third body 291 with a T-shaped longitudinal section, which is located in the groove 211. The end of the third body 291 is located outside the groove 211, and a fourth body 292 with a Z-shaped longitudinal section extends outward. The end of the fourth body 292 is fixedly connected to the second adapter 35 by a positioning screw 293.

[0037] To improve installation accuracy and reduce installation difficulty, and to enable three-dimensional adjustment of the system, such as... Figure 9 As shown, in each of these aluminum plate structures 2, the second body 282 of the upper hanging member 28 is provided with a vertical adjusting screw hole, and an adjusting bolt 284 is provided in the adjusting screw hole. The bottom end of the adjusting bolt 284 abuts against the top surface of the corresponding fourth plate 363 to finely adjust the installation position of the aluminum plate structure 2 in the vertical direction. Figure 7 As shown, the first fixing plate 341 of the first adapter 34 has a horizontal first elongated hole 345, and the second fixing bolt 343 is located in the first elongated hole 345 to adjust the position of the aluminum plate structure 2 in the horizontal direction. Similarly, the first side plate 342 of the first adapter 34 has a vertical second elongated hole (not shown in the figure), and the third fixing bolt 344 is located in the second elongated hole to coarsely adjust the position of the aluminum plate structure 2 in the vertical direction. In addition, the in-and-out position and vertical position of the aluminum plate structure 2 can be adjusted by adjusting the first fixing screw 311 of the second adapter 35. Furthermore, the vertical position of the aluminum structure can be adjusted by adjusting the position of the third adapter 36 in the second vertical groove 353.

[0038] To improve the overall system's sealing and insulation performance, such as Figure 2 , Figure 3 As shown, baffles 37 are provided on the outer sides of the vertical square tube 31 and the horizontal square tube 32. The top and bottom folded edges of the baffles 37 are fixed to the outer side of the corresponding horizontal square tube 32 by L-shaped corner brackets. The two side folded edges of the baffles 37 are fixed to the outer side of the first plate 351 of the corresponding second adapter 35 by L-shaped corner brackets. Insulation cotton 38 can also be provided on the inner side of the baffles 37. By using metal baffles 37 and insulation cotton 38, the insulation and sealing effect of the system can be achieved. In order to clearly show the adapter structure 3, the present invention Figure 2 and Figure 3 Only a portion of the insulation cotton 38 is shown; in reality, it covers the entire back of the baffle 37.

[0039] This invention relates to an assembled inclined triangular folding aluminum plate molding system, which solves the application problem of complex irregular folding aluminum plate systems on facades, greatly reduces the on-site installation workload, ensures the accuracy, safety and reliability of decorative strip molding and the sealing performance of the system, and can prevent the wind-blown effect of triangular folding aluminum plates under upward wind loads.

[0040] This invention is defined by the claims. However, based on this, those skilled in the art can make various obvious changes or modifications, all of which should be within the main spirit and protection scope of this invention.
