Description

Technical Field

[0001] The invention relates to an aluminum plate curtain wall technology, in particular to a fixed connection structure of special-shaped folded perforated aluminum plates. Background Art

[0002] In recent years, with the increasing demand for three-dimensional and parametric modeling in architectural facade design, special-shaped folded perforated aluminum curtain wall systems have been widely used in the facades of large public buildings due to their unique lighting effects and functional characteristics. By combining CNC punching with three-dimensional folding technology, these curtain wall systems can achieve functions such as sunshade and ventilation while creating a dynamic three-dimensional texture effect.

[0003] In the prior art, there are steel adapters for fixing the special-shaped parts to the main structure, aluminum sub-frames connected by a three-dimensional adjustable bolt group, and perforated aluminum plate units fixed by angle brackets. For example, the Chinese utility model patent "A multi-angle adjustable aluminum plate combined connector" (CN 217268219 U) includes a keel, the bottom left and right sides of which are fixedly connected to clamping blocks, the bottom left and right sides of the keel are provided with connector 1 at positions relative to the clamping blocks, the bottom of the connector 1 is rotatably connected to connector 2, the opposite surfaces of the two connectors 2 are fixedly connected to aluminum plate panels by positioning bolts, the bottoms of the two connectors 1 are provided with pressure blocks, the pressure blocks are fixedly connected to the bottom of the keel by screw 1, the bottom of the pressure blocks are fixedly connected to a decorative card holder by screw 2, and the bottom of the decorative card holder is clamped with a decorative card strip.

[0004] As mentioned above, the relative angle of the left and right adjacent aluminum panels can be adjusted by rotating the connection between connectors 1 and 2. However, the end face of the frame for the fixing screws is always perpendicular to the angle bisector of the panel. As the panel angle changes, the frame also needs to continuously deflect with the panel angle, making the frame's processing and positioning more difficult and limiting its angle adjustment range.

[0005] Furthermore, there's no mention of adjusting the vertical angle of the aluminum panels. Existing technology primarily focuses on horizontal adjustment. When faced with facade decoration involving non-vertical surfaces or multiple curved surfaces with varying angles, the upper and lower sides form different angles, requiring custom connectors at each angle to be installed and secured by welding. This method lacks adjustability, cannot accommodate machining and installation errors, increases material costs, and prolongs the construction period.

[0006] Therefore, it is necessary to design a connection structure that is simple in structure and has adaptability to meet the various needs of the market. Summary of the Invention

[0007] The purpose of the present invention is to provide a special-shaped folded perforated aluminum plate fixed connection structure, which simplifies the connection structure and improves the construction efficiency through structural improvement, meeting the installation requirements of multi-angle adjustment changes.

[0008] To achieve the above-mentioned object, the technical solution adopted by the present invention is: a fixed connection structure of a special-shaped folded perforated aluminum plate, comprising a steel frame and a connection component fixed to the aluminum plate, the connection component comprising a horizontal support and a flip connector provided at the front end of the horizontal support, the horizontal support being located at the joint between vertically adjacent aluminum plates, the flip connector spanning the vertically adjacent aluminum plates and connected to the horizontal support via studs, and the horizontal support being fixedly connected to the steel frame;

[0009] The flip connector includes upper and lower pages and an intermediate connecting page. The upper and lower pages are fixed to the upper and lower adjacent aluminum plates respectively. The front end of the intermediate connecting page is rotatably connected to the upper and lower pages via a pin, and the rear end thereof is fixedly connected to the horizontal support.

[0010] or,

[0011] The flip connector includes upper and lower hinge connectors, which are respectively located on the upper and lower sides of the horizontal support. Each hinge connector includes a first leaf connected to the aluminum plate and a second leaf connected to the horizontal support. The first leaf and the second leaf are rotatably connected via a pin. The angle between the first leaf and the second leaf is adapted to the angle between the aluminum plate and the horizontal support.

[0012] The horizontal support includes a connecting section whose front end is fixed to the flip connector, and a fixing section whose rear end is fixed to the steel frame. The position of the horizontal support on the steel frame is obtained based on IBM modeling and meets the bearing capacity requirements.

[0013] In the above technical solution, the horizontal support is Y-shaped, including left and right forked connecting sections at the front end, which correspond to the splicing planes of adjacent aluminum plates on both sides, and the rear end merges the left and right connecting sections into a fixed straight section, which is welded and fixed to the steel frame.

[0014] In the above technical solution, the horizontal support is in a unilateral Y-shape, including a connecting section with its front end bent to one side, corresponding to the splicing plane of adjacent aluminum plates on both sides, and a fixed straight section welded and fixed to the steel frame at the rear end.

[0015] A further technical solution is that the inclination of the connecting section in the horizontal support is consistent with the inclination of the aluminum plate, and the fixed straight section is perpendicular to the steel frame.

[0016] In the above technical solution, each of the aluminum plates is provided with a shaped corner in the middle and butt flanges on both sides. The adjacent aluminum plates are fixed by riveting after being fitted together by the butt flanges. The adjacent aluminum plates are connected vertically by the flip connector. According to the design requirements, the flip connector is selected and adjusted:

[0017] A) The angle between the upper and lower leaves or the upper and lower hinge connectors and the horizontal support;

[0018] B) the angle between the upper and lower leaves; or

[0019] C) The angle between the upper and lower hinge connectors;

[0020] One or two of A, B, and C can meet the needs of special-shaped design.

[0021] A further technical solution is that the flip connecting piece includes upper and lower pages and an intermediate connecting page, a connecting lug is provided between the upper and lower pages, a first pin hole is provided on the connecting lug, a connecting groove is provided at the front end of the intermediate connecting page to be plugged into the connecting lug, a second pin hole is provided on the groove wall of the connecting groove to penetrate the first pin hole, the connecting lug is plugged into the connecting groove, and the pin shaft passes through the first and second pin holes from one end to rotate and connect the two.

[0022] Another technical solution is that the upper and lower pages are respectively provided with a plurality of vertical adjustment long holes, the upper and lower pages are fixed to the aluminum plates on the corresponding sides by countersunk pins, and the freedom of up and down adjustment is obtained through the vertical adjustment long holes; the middle connecting page is provided with a plurality of distance adjustment long holes arranged perpendicular to the horizontal plane of the aluminum plate, and the freedom of front and rear position adjustment between the horizontal support is obtained through the distance adjustment long holes; the upper and lower pages and the middle connecting page are respectively provided with anti-slip teeth.

[0023] In the above technical solution, the upper and lower hinge connecting parts respectively include a first page piece and a second page piece, wherein the first page piece and the second page piece are respectively provided with a first adjustment long hole and a second adjustment long hole, wherein the first page piece is fixed to the aluminum plate on the corresponding side by a countersunk pin, and the upward and downward adjustment freedom is obtained through the first adjustment long hole, and the second page piece is fixed to the horizontal support by a stud, and the front and rear adjustment freedom is obtained through the second adjustment hole; anti-slip teeth are respectively provided on the opposite surfaces of the first page piece and the second page piece.

[0024] In the above technical solution, the steel frame includes longitudinal columns and horizontal beams, which are fixed in pairs to form a frame structure, and the horizontal supports are welded and fixed to the horizontal beams.

[0025] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0026] 1. The present invention utilizes flip connectors to longitudinally connect adjacent aluminum panels. By rotating the pins, the angle between the upper and lower aluminum panels in each area and the main wall surface can be adjusted. This means adjusting the front and rear spatial positions of the aluminum panels relative to the main wall surface, thereby forming a three-dimensional shape for the aluminum panels and meeting the requirements of special-shaped curtain walls.

[0027] 2. The hinged connector and the horizontal support are connected to achieve an adjustable connection between the upper and lower vertical aluminum panels. The freely adjustable angle between the first and second leaves can adapt to the upper and lower aluminum panels that are connected at irregular angles. This eliminates the need for customized connectors for each angle, saving connector costs. The freely adjustable hinge structure also facilitates installation, simplifies construction difficulty, and improves installation efficiency.

[0028] 3. The horizontal support is welded and fixed to the steel frame (similar to a beam). Its distribution on the steel frame is calculated using IBM modeling software to ensure the accuracy, firmness and stability of the connection points between the hinge connector and the aluminum plate. The horizontal support is made of stamped steel plate, which has strong bearing capacity and good connection stability.

[0029] 4. In this invention, seamless adjustment between wide angles is achieved using a single set of standard components in all three positions (A, B, and C). The key to this design is its simplified fabrication and positioning of the frame. Regardless of how the aluminum panels are tilted (outward or inward), the inner frame remains horizontal, significantly simplifying fabrication and positioning. Even if adjacent aluminum panels are tilted outward or inward, they can be simultaneously secured to the same horizontal steel plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The following description is only a preferred embodiment of the present invention and does not limit the scope of the present invention. In addition, the terms "vertical", "horizontal", "top", "bottom", "front", "back", "up", "down", "inside", "outside" and the like mentioned in the embodiments of the present invention indicate the orientation or position relationship based on the attached Figure 1 or attached Figure 7 The orientation or position relationship shown, or the orientation or position relationship in which the product is usually placed when in use, is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or component referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention. Figure 1-12 The present invention is described in detail with reference to the embodiments.

[0044] Example 1: See Figure 1-7As shown, a special-shaped folded perforated aluminum plate fixed connection structure includes a steel frame 1 and a connection component fixed to the aluminum plate 2. The connection component includes a horizontal support 3 and a flip connector provided at the front end of the horizontal support 3. The horizontal support 3 is located at the joint between vertically adjacent aluminum plates 2. The flip connector 4 spans the vertically adjacent aluminum plates 2 and is connected to the horizontal support 3 via studs 14. The horizontal support 3 is fixedly connected to the steel frame.

[0045] The flip connector 4 includes upper and lower pages and an intermediate connecting page 18. The upper and lower pages are fixed to the upper and lower adjacent aluminum plates 2 respectively. The front end of the intermediate connecting page 18 is rotatably connected to the upper and lower pages via a pin 7, and the rear end thereof is fixedly connected to the horizontal support 3 via a stud 14.

[0046] The horizontal support 3 is Y-shaped, including a front end with left and right bifurcated connecting sections 10, which correspond to the splicing planes of adjacent aluminum plates 2 on both sides, and a rear end merging the left and right connecting sections 10 into a fixed straight section 11, which is welded and fixed to the steel frame 1;

[0047] The steel frame 1 includes longitudinal columns and horizontal beams 19, which are fixed in pairs to form a frame structure. The horizontal supports 3 are welded and fixed to the horizontal beams 19. The position of the horizontal supports 3 on the steel frame 1 is obtained based on IBM modeling and meets the bearing capacity requirements.

[0048] Specifically:

[0049] like Figure 1 As shown, the horizontal support 3 in the middle of the curtain wall is Y-shaped, and the horizontal supports 3 on both sides are single-sided Y-shaped. Both single-sided or double-sided Y-shaped horizontal supports 3 include a connecting section 10 and a fixed straight end 11. On the edge side, the aluminum plate 2 is bent inward and fixed to the single-sided Y-shaped horizontal support 3 by a rim 20. The inclination of the connecting section 10 in the horizontal support 3 is consistent with the inclination of the aluminum plate 2, that is, Figure 1 In the middle, angle A is 24° (variable) = angle B is 24° (variable), and the fixed straight section 11 is perpendicular to the horizontal beam 19 .

[0050] Each aluminum plate 2 is provided with a shaped corner 8 in the middle and a butt flange 9 on both sides. The adjacent aluminum plates 2 are fitted together by the butt flange 9 and then riveted 21. The adjacent aluminum plates are connected vertically by the flip connector 4. According to the design requirements, the angle between the upper and lower pages and the middle connecting page 18 in the flip connector 4 can be adjusted to meet the needs of special-shaped design. Figure 6 、 7As shown, a shape similar to a lotus petal 22 needs to be formed. In this design, the aluminum curtain wall has multiple curved surfaces for adjustment, including a three-dimensional arc protruding outward from the aluminum plate 2, which is closer to the three-dimensional shape of the lotus petal 22. When this embodiment is used, the inclination angles of the upper and lower sheets can be adjusted separately to obtain the effect shown in the figure.

[0051] The flip connector 4 includes upper and lower sheets and a middle connecting sheet 18. Figure 5 As shown, a connecting lug 23 is provided between the upper and lower pages, and a first pin hole 24 is provided on the connecting lug 23. A connecting groove 25 is provided at the front end of the intermediate connecting page 18 to be plugged into the connecting lug 23. A second pin hole 26 is provided on the groove wall of the connecting groove 25 to penetrate the first pin hole 24. The connecting lug 23 is plugged into the connecting groove 25, and the pin shaft 7 passes through the first and second pin holes from one end to rotate and connect the two.

[0052] Alternatively, the upper page 16 and the lower page 17 are split structures, with the connecting lugs on each side of the upper and lower parts being spliced ​​with the connecting grooves 25 of the intermediate connecting page 18 and connected together through the pin 7. The difference from the above is that the upper page 16 and the lower page 17 can be adjusted at an angle relative to the intermediate connecting page 18, which makes them more flexible to use. However, the consistency and accuracy of the combination need to be considered during installation.

[0053] The upper and lower pages are respectively provided with a plurality of vertical adjustment long holes 12, which are fixed to the aluminum plates 2 on the corresponding sides by countersunk pins 13, and the freedom of upward and downward adjustment is obtained through the vertical adjustment long holes 12; the middle connecting page 18 is provided with a plurality of distance adjustment long holes 12 arranged perpendicular to the horizontal plane of the aluminum plate 2, and the freedom of front and rear position adjustment between the horizontal support 3 is obtained through the distance adjustment long holes 12; the upper and lower pages and the middle connecting page 18 are respectively provided with anti-slip teeth 15 to improve the locking force of the countersunk pins 13.

[0054] like Figure 7 As shown, given the location of the lotus petal-shaped transverse seams, the upper and lower panels can be essentially considered a single plane within a small area. This embodiment simplifies the structure of the flip connector 4. In particular, during installation and positioning, regardless of the angles of the upper and lower panels, the intermediate connecting panel 18 and the horizontal support 3 remain statically fixed, facilitating on-site operation. Furthermore, installation of the aluminum panel 2 is simplified by first aligning the hinges forward and backward. Once the lower panel is installed, the hinge angle is automatically set, and the upper panel can be perforated on-site along the hinge, eliminating the need for secondary alignment and installation.

[0055] Example 2: See Figures 8-12As shown, a special-shaped folding perforated aluminum plate fixed connection structure includes a steel frame 1 and a connection component fixed to the aluminum plate 2, the connection component includes a horizontal support 3 and a flip connection member 4 arranged on both sides of the horizontal support 3, the horizontal support 3 is located at the joint of vertically adjacent aluminum plates 2, each of the flip connection members 4 includes a first page 5 connected to the aluminum plate 2 and a second page 6 connected to the horizontal support 3, the first page 5 and the second page 6 are rotatably connected by a pin shaft 7, and the angle between the first page 5 and the second page 6 is adapted to the angle between the aluminum plate 2 and the horizontal support 3; the horizontal support 3 is fixedly connected to the steel frame 1.

[0056] like Figure 9-11 As shown, the angle between the aluminum plate 2 and the horizontal support 3 is a conventional right angle ( Figure 9 ), and also at an acute angle ( Figure 10 ) and obtuse angle ( Figure 11 ), the angle is determined by the design of the aluminum plate 2 and varies in size. The flip connector 4 of this embodiment can be adjusted arbitrarily by the relative rotation between the first leaf 5 and the second leaf 6 to meet the needs of different angles.

[0057] like Figure 8 、 12 As shown, the aluminum plate 2 is provided with a folded corner 8 in the middle and a butt flange 9 on both sides. The adjacent aluminum plates 2 on the left and right are fixed by riveting after being fitted together through the butt flange 9. The upper and lower butt-jointed aluminum plates 2 are connected to the horizontal support 3 through upper and lower hinge connectors respectively. The butt flange 9 is used to extend the horizontal aluminum plate facing wall. As shown in the figure, an aluminum plate 2 with a folded corner 8 can be selected to ensure the flatness of the aluminum plate 2 (the material of the aluminum plate itself determines that it is easy to deform). When the last piece on the side is installed, the butt flange 9 is the side edge. Figure 9 As stated.

[0058] The horizontal support 3 includes a connecting section 10 at the front end corresponding to the splicing plane of the upper and lower aluminum plates, and a fixing section 11 at the rear end fixed to the steel frame 1. The position of the horizontal support 3 on the steel frame 1 is obtained based on IBM modeling.

[0059] like Figure 8 As shown, the horizontal support 3 is Y-shaped, comprising a connecting section 10 with two forked ends at the front end, corresponding to the joint planes of the left and right adjacent aluminum plates, and a rear end that merges into a fixed end 11, which is welded to the steel frame 1. In this embodiment, a positive angle connection method is adopted, that is, the connecting sections on both sides of the horizontal support are located at the protruding corners of the adjacent aluminum plates.

[0060] like Figure 9-11As shown, the first leaf 5 and the second leaf 6 are respectively provided with adjustment long holes 12 (waist-shaped holes), wherein the first leaf 5 is fixed to the aluminum plate 2 on the corresponding side by a countersunk pin 13, and the second leaf 6 is fixed to the horizontal support 3 by a stud 14; anti-slip teeth 15 are respectively provided on the opposite surfaces of the first leaf 5 and the second leaf 6.

[0061] During construction, the steel frame 1 is first fixed to the wall, and then the horizontal supports 3 are distributed on the steel frame 1 according to the IBM modeling data. Finally, the aluminum plates 2 are fixed on the horizontal supports 3 in sequence. During this process, the front and back relationship between the aluminum plates and the wall is adjusted by flipping the adjustment long holes 12 on the connecting parts 4. After determining the front and back positions of the aluminum plates 2, the angle between the vertical aluminum plates 2 and the horizontal supports 3 is adjusted, and the flanges 9 of the adjacent horizontal aluminum plates are fixed to complete the installation of the entire aluminum plate finish.

[0062] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
