Side auxiliary frames are also provided to fix the corrugated reinforcing ribs, increase the overall mechanical properties, and the setting of the side auxiliary frames can also make the side auxiliary frames press the corrugated reinforcing ribs to reduce the force on the structural adhesives and further protect the structural adhesives.

Description

Technical Field

[0001] The present invention belongs to the technical field of aluminum veneer curtain walls, and particularly relates to a three-dimensional fluorocarbon simulated stone paint aluminum veneer and a forming method thereof. Background Art

[0002] Generally, after surface pretreatment such as chromating, the aluminum veneer curtain wall is then treated with fluorocarbon spraying. The fluorocarbon coating has excellent corrosion resistance and weather resistance, can resist acid rain, salt spray and various air pollutants, has extremely good heat and cold resistance, can resist strong ultraviolet radiation, can maintain no fading and no powdering for a long time, and has a long service life.

[0003] The aluminum veneer can be stamped to form a three-dimensional stone pattern as a curtain wall. Combined with fluorocarbon simulated stone paint, it can achieve a better aesthetic effect and has a stronger visual impact. However, the problems arising therefrom are as follows: the hardness of the aluminum plate is relatively low, and a relatively large aluminum veneer is prone to deformation and vibration under the influence of wind, which is even more serious after stamping to form a three-dimensional stone pattern. The fluorocarbon paint has poor elasticity and is prone to paint peeling and cracking over time, while the conventional reinforcing ribs have insufficient protection ability and it is difficult to avoid paint peeling and cracking. Summary of the Invention

[0004] The purpose of the present invention is to provide a three-dimensional fluorocarbon simulated stone paint aluminum veneer and a forming method thereof to solve the above problems.

[0005] The present invention achieves the above purpose through the following technical solutions:

[0006] A three-dimensional fluorocarbon simulated stone paint aluminum veneer, including an aluminum panel. The surface of the aluminum panel is formed with a three-dimensional stone pattern by stamping. The three-dimensional stone pattern forms a groove on the back of the aluminum panel. The upper and lower ends of the aluminum panel are bent backward to form corrugated reinforcing ribs. Among them, the trough of the corrugated reinforcing rib fits with the groove, and a structural adhesive is provided at the fitting position.

[0007] The left and right ends of the aluminum panel are bent backward to form side auxiliary frames. A clamping structure for clamping the side auxiliary frames is provided between the two side auxiliary frames. Among them, the clamping structure includes a long rod and nuts provided at both ends of the long rod.

[0008] As a further optimized scheme of the present invention, a fluorocarbon coating is applied to the front surface of the aluminum panel. The fluorocarbon coating is a prior art and has excellent corrosion resistance and weather resistance.

[0009] As a further optimized scheme of the present invention, the corrugated reinforcing rib and the aluminum panel enclose a corrugated cavity for the long rod to pass through. The setting of the corrugated reinforcing rib can increase the protection ability and protection area, and hide the long rod.

[0010] As a further optimization solution of the present invention, external threads corresponding to the nuts are respectively provided at both ends of the long rod, and through holes corresponding to the long rod are penetrated on the surface of the side auxiliary frame. The two side auxiliary frames are clamped towards the corrugated reinforcing rib by the long rod, so that the side auxiliary frame and the corrugated reinforcing rib are fixed to each other, increasing the overall anti-deformation ability.

[0011] As a further optimization solution of the present invention, an outer eaves for buckling the corrugated reinforcing rib is further provided at the edge of the side auxiliary frame, in order to prevent the corrugated reinforcing rib from detaching from the fitting with the groove and reducing the stress on the structural adhesive.

[0012] As a further optimization solution of the present invention, a shielding eaves is provided at the connection between the side auxiliary frame and the aluminum panel. The shielding eaves includes a first bend and a second bend. The purpose of setting the shielding eaves is to hide the long rod and the nut, playing a role in external aesthetics.

[0013] As a further optimization solution of the present invention, an angle code is fixedly connected to the end of the long rod through a nut, and the angle code is fixedly connected to the keel through a fixing bolt. The nut can fix the angle code on the side auxiliary frame together.

[0014] In order to produce the above aluminum single panel, the present invention also proposes a forming method based on the above three-dimensional fluorocarbon simulated stone paint aluminum single panel, including the following steps:

[0015] S1: Blank forming: Cut the aluminum plate blank into a cross shape, and punch a three-dimensional stone pattern in the central area of the cross-shaped blank to form blank A;

[0016] S2: Corrugated reinforcing rib forming: Punch corrugations at the upper and lower ends of blank A, bend the corrugations 180° to fit the concave surface of the three-dimensional stone pattern, and punch the wave trough of the corrugation again so that the wave trough of the corrugation forms a fitting surface to be embedded with the groove. Finally, inject structural adhesive at the embedding part to form blank B;

[0017] S3: Side auxiliary frame forming: Punch holes in the side edges of the left and right ends of blank B, and then perform stamping and bending on the side edges to form an outer eaves, wherein the angle between the outer eaves and the side auxiliary frame is 90° - 100°. Perform stamping and bending again to form a 90° second bend, and finally perform stamping and bending to form a 180° first bend to form blank C;

[0018] S4: Side auxiliary frame fixing: Insert a long rod into the through hole on the surface of the side auxiliary frame of blank C, and screw nuts at both ends of the long rod 21 to complete the fixation to form the aluminum single panel.

[0019] The beneficial effects of the present invention are as follows:

[0020] The present invention combines multiple corrugated reinforcing ribs with the concave surface of the three-dimensional stone pattern, and structural adhesive is provided at the combination, which plays a protective role for the aluminum panel, effectively preventing the aluminum panel from vibrating back and forth in strong wind weather. Among them, the corrugated reinforcing ribs can also protect the structural adhesive and increase the service life of the structural adhesive. A side auxiliary frame is also provided to fix the corrugated reinforcing ribs, increasing the overall mechanical properties. Moreover, the setting of the side auxiliary frame can also press the corrugated reinforcing ribs tightly, reducing the stress on the structural adhesive and further protecting the structural adhesive.

Detailed Description of the Embodiment

[0027] The following further describes the present application in detail with reference to the accompanying drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0028] Embodiment 1

[0029] As Figures 1-4 shown, a three-dimensional fluorocarbon simulated stone paint aluminum single panel includes an aluminum panel 1. The surface of the aluminum panel 1 is formed with a three-dimensional stone pattern 11 by stamping. The three-dimensional stone pattern 11 forms a groove 12 on the back of the aluminum panel 1. The upper and lower ends of the aluminum panel 1 are bent towards the back to form corrugated reinforcing ribs 13. Among them, the trough of the corrugated reinforcing rib 13 is fitted with the groove 12, and structural adhesive 3 is provided at the fitting place;

[0030] For large-area exterior curtain wall aluminum panels, affected by strong winds, a pressure difference is formed at both ends of the aluminum panels, which has the effect of sucking and pushing the aluminum panel 1, easily causing micro-deformation of the aluminum panel 1. Over time, the fluorocarbon paint on the surface is prone to cracking. Therefore, a corrugated reinforcing rib 13 is provided, and the trough of the corrugated reinforcing rib 13 is fitted with the groove 12 on the back of the three-dimensional stone pattern 11 through stamping, and a structural adhesive 3 is provided at the fitting position, which can effectively prevent the aluminum panel 1 from vibrating back and forth and protect the fluorocarbon coating 101.

[0031] The left and right ends of the aluminum panel 1 are bent backward to form side auxiliary frames 16, and a clamping structure for clamping the side auxiliary frames 16 is provided between the two side auxiliary frames 16. Among them, the clamping structure includes a long rod 21 and nuts 23 provided at both ends of the long rod 21.

[0032] The function of the side auxiliary frame 16 is to fix the corrugated reinforcing rib 13 and fix the entire aluminum single panel on the keel. By setting the clamping structure, the side auxiliary frame 16 is fixed to the corrugated reinforcing rib 13, improving the overall mechanical performance. In order to prevent the corrugated reinforcing rib 13 from turning outwards and causing the structural adhesive 3 to be subjected to tension, an outer eaves 17 for buckling the corrugated reinforcing rib 13 is further provided at the edge of the side auxiliary frame 16. The outer eaves 17 can be set to 90° or 100°. The outer eaves 17 has a certain inclination angle, which can press the corrugated reinforcing rib 13 during fixation and reduce the force on the structural adhesive 3.

[0033] The front surface of the aluminum panel 1 is coated with a fluorocarbon coating 101. The fluorocarbon coating 101 is a prior art, which has a good surface self-cleaning function, does not adsorb dust, and is corrosion-resistant, high-temperature and low-temperature resistant. Combined with the three-dimensional stone pattern 11, it has a more three-dimensional aesthetic effect, making the exterior curtain wall more visually appealing.

[0034] The corrugated reinforcing rib 13 and the aluminum panel 1 enclose a corrugated cavity 131. External threads 22 corresponding to the nuts 23 are provided at both ends of the long rod 21, and through holes corresponding to the long rod 21 are provided on the surface of the side auxiliary frame 16. The corrugated cavity 131 is for the long rod 21 to pass through, facilitating the mutual clamping of the two side auxiliary frames 16 through the long rod 21. Among them, the corrugated cavity 131 is beneficial for the concealment and fixation of the long rod 21.

[0035] A shielding eaves is provided at the connection between the side auxiliary frame 16 and the aluminum panel 1. The shielding eaves includes a first bend 14 and a second bend 15. The purpose of setting the shielding eaves is to conceal the long rod 21 and the nuts 23 and conceal the components as much as possible when looking directly at the aluminum panel 1 from the outside.

[0036] An angle code 4 is also fixedly connected to the end of the long rod 21 through the nut 23. The angle code 4 is fixedly connected to the keel 5 through a fixing bolt 6, which is convenient for direct connection with the keel 5 without additional setting of the angle code 4 and the riveting position.

[0037] To produce the above aluminum single panel, the present invention also provides a forming method for the three-dimensional fluorocarbon simulated stone paint aluminum single panel as described above, comprising the following steps:

[0038] S1: Blank forming: Cut the aluminum plate blank into a cross shape, as Figure 5 shown, and stamp out a three-dimensional stone pattern 11 in the central area of the cross-shaped blank ( Figure 5 the three-dimensional stone pattern stamping area in), to form blank A;

[0039] S2: Corrugated reinforcing rib 13 forming: Stamp out corrugations ( Figure 5 the corrugated reinforcing rib stamping area in) at the upper and lower ends of blank A, and bend the corrugations 180° to fit with the concave surface of the three-dimensional stone pattern 11, and stamp the troughs of the corrugations again so that the troughs of the corrugations form a fitting surface 132 to fit with the grooves 12, and finally inject structural adhesive 3 at the fitting place to form blank B;

[0040] S3: Side auxiliary frame 16 forming: Punch holes in the side edges of the left and right ends of blank B, and then perform stamping and bending on the side edges ( Figure 5 the side auxiliary frame stamping area in) to form an outer eaves 17 of 90°, perform stamping and bending again to form a second bend 15 of 90°, and finally perform stamping and bending to form a first bend 14 of 180° to form blank C;

[0041] S4: Fixing of side auxiliary frame 16: Pass a long rod 21 through the through holes on the surface of the side auxiliary frame 16 of blank C, and screw nuts 23 at both ends of the long rod 21 to complete the fixation to form the aluminum single panel.

[0042] In the above forming method, by providing multiple corrugated reinforcing ribs 13 and combining with the aluminum panel 1 through structural adhesive, the anti-deformation ability of the aluminum panel 1 in the front and back directions can be improved, and when forming, the troughs of the corrugated reinforcing ribs 13 and the grooves 12 of the three-dimensional stone pattern 11 are stamped again, which can increase the area and fitting degree of the fitting surface, and further improve the overall mechanical properties.

[0043] The above embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
