Description

Technical Field

[0001] This utility model relates to a decorative panel, specifically a multi-faceted composite panel with curved surfaces. Background Technology

[0002] With the upgrading of architectural aesthetics, the exterior decoration of buildings is gradually breaking away from traditional planar designs and developing towards complex geometric forms such as curved surfaces and polyhedra. In recent years, a large number of urban landmark buildings, commercial complexes and cultural venues have adopted streamlined appearances, driving a surge in market demand for curved decorative panels.

[0003] Aluminum honeycomb panels employ a sandwich composite structure of aluminum alloy faceplate, backplate, and honeycomb core, offering advantages such as lightweight and high strength. However, when using aluminum honeycomb panels to create multi-faceted composite panels, complex geometric structures combining polyhedrons and curved surfaces require multi-segment cutting and splicing. This increased number of seams negatively impacts structural strength, necessitating solutions to the complex structure and strength-related issues. Utility Model Content

[0039] The following describes some of the possible embodiments of this utility model, intended to provide a basic understanding of the utility model, and is not intended to identify the key or decisive elements of the utility model or limit the scope of protection to be provided. It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose other interchangeable implementations without changing the essential spirit of the utility model. Therefore, the following specific embodiments are merely illustrative examples of the technical solution of this utility model and should not be considered as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0040] (Example 1)

[0041] See Figures 1 to 8 The curved polyhedral composite plate of this embodiment includes a first plate 1, a second plate 2, a third plate 3, a fourth plate 4, and a connecting assembly; wherein the first plate 1, the second plate 2, the third plate 3, and the fourth plate 4 are sequentially spliced ​​to form the plate body; the connecting assembly includes a trapezoidal connector 5 and a corner bracket 6, which are used to connect the plates to each other.

[0042] The first plate 1, the second plate 2, the third plate 3, and the fourth plate 4 are aluminum honeycomb panels, each comprising a surface aluminum plate, a honeycomb core, and an aluminum back plate. The honeycomb core is disposed between the surface aluminum plate and the aluminum back plate, and the surface aluminum plate is bonded and fixed to the honeycomb core, and the honeycomb core is bonded and fixed to the aluminum back plate. The surface aluminum plate serves as a decorative surface.

[0043] See Figure 1 For the panel portion, the first panel 1 and the third panel 3 are respectively connected to the two sides of the width direction X of the second panel 2. The first panel 1 is not coplanar with the second panel 2 (the non-coplanarity means that the decorative surface of the first panel 1 is not on the same plane as the decorative surface of the second panel 2, the same below). The third panel 3 is also not coplanar with the second panel 2, and the first panel 1 and the third panel 3 are located on the same side of the thickness direction Z of the second panel 2.

[0044] The second plate 2 and the fourth plate 4 are respectively connected to the two sides of the third plate 3 in the height direction, and the fourth plate 4 is not coplanar with the third plate 3.

[0045] See Figure 2-5 and Figure 9 After the first plate 1 and the second plate 2 are spliced ​​together, the interior angle at the splice point is 45° to 150°. Figure 2-5 The example shown is an embodiment where the joint is at an obtuse angle. Figure 9 The example shown is an embodiment where the joint is an acute angle.

[0046] After the second plate 2 and the third plate 3 are spliced ​​together, the interior angle at the splicing point is 45° to 150°. Figure 5 The angle at the joint is obtuse; after the third plate 3 and the fourth plate 4 are spliced ​​together, the interior angle at the splice point is 75° to 120°. Figure 5 (90° in the middle).

[0047] See Figure 10 The first plate 1 and the second plate 2 are the two plates with larger surface areas in this embodiment. When applied, their surfaces are the main decorative surfaces. When the inner corners of the first plate 1 and the second plate 2 are facing down after being spliced ​​together, the first plate 1 and the second plate 2 form a herringbone roof shape.

[0048] Furthermore, in this embodiment, the second plate 2 is a curved plate, that is, the surface of the second plate 2 is not flat, while the other plates are flat plates.

[0049] In some embodiments, both the first plate 1 and the second plate 2 are curved panels, the surface of the first plate 1 is non-planar, and the surface of the second plate 2 is non-planar.

[0050] See Figure 1 , Figure 5 and Figure 7 After the first plate 1 and the second plate 2 are spliced ​​together, they are connected by corner brackets 6. The corner brackets 6 are set at intervals along the length Y of the polyhedral composite plate, with equal spacing preferred.

[0051] The corner bracket 6 includes a first wing plate 6-1 and a second wing plate 6-2. The interior angle of the included angle between the first wing plate 6-1 and the second wing plate 6-2 is the same as the interior angle of the included angle between the first plate body 1 and the second plate body 2.

[0052] Specifically, refer to Figure 7 Angle bracket 6 is located on one side of the inner corner of the first plate 1 and the second plate 2. The first wing plate 6-1 of the angle bracket 6 is attached to the aluminum back plate of the first plate 1 and fixed to the first plate 1 by fasteners; the second wing plate 6-2 is attached to the aluminum back plate of the second plate 2 and fixed to the second plate 2 by fasteners.

[0053] See Figure 1 When the second plate 2 is a curved plate, the section of the second plate 2 closest to the first plate 1 in the width direction X, which is the section used for corner bracket connection (the section between the dashed line and the first plate 1, with a width equal to or slightly greater than the width of the wing plate), is flat, which facilitates the connection of the corner bracket 6.

[0054] When the first plate 1 is a curved plate, similarly, the section used for corner bracket connection is a flat plate, which facilitates the connection of corner bracket 6.

[0055] See Figure 1 , Figures 4 to 6The three-sided geometric structure formed by the second plate 2, the third plate 3, and the fourth plate 4 is connected by trapezoidal connectors 5. Along the length Y of the polyhedral composite plate, the trapezoidal connectors 5 are spaced apart, preferably with equal spacing.

[0056] See Figure 6 The trapezoidal connector 5 includes a first connecting plate 5-1, a second connecting plate 5-2, a third connecting plate 5-3, and a fourth connecting plate 5-4. The size and shape of the trapezoidal connector 5 are adapted to the three-sided geometric structure formed by the second plate 2, the third plate 3, and the fourth plate 4.

[0057] Specifically, the first connecting plate 5-1 is a quadrilateral plate, and the second connecting plate 5-2, the third connecting plate 5-3 and the fourth connecting plate 5-4 are connected to the same side of the thickness direction of the first connecting plate 5-1, and are respectively connected to the three edges of the same side surface of the first connecting plate 5-1; the end faces of the second connecting plate 5-2, the third connecting plate 5-3 and the fourth connecting plate 5-4 are joined together to form an open trapezoid.

[0058] The second connecting plate 5-2 and the fourth connecting plate 5-4 are connected to both sides of the third connecting plate 5-3 in the height direction. The interior angle of the angle between the second connecting plate 5-2 and the third connecting plate 5-3 is the same as the interior angle of the angle between the second plate 2 and the third plate 3. The interior angle of the angle between the fourth connecting plate 5-4 and the third connecting plate 5-3 is the same as the interior angle of the angle between the fourth plate 4 and the third plate 3.

[0059] See Figure 4 and Figure 6 When the trapezoidal connector 5 is used to connect the second plate 2, the third plate 3, and the fourth plate 4 to form a three-sided geometric structure, the second connecting plate 5-2 is connected to the second plate 2 by fasteners, the third connecting plate 5-3 is connected to the third plate 3 by fasteners, and the fourth connecting plate 5-4 is connected to the fourth plate 4 by fasteners (fasteners are not shown). Preferably, the second connecting plate 5-2 is attached to the aluminum back plate of the second plate 2 and then connected to the second plate 2 by fasteners; the third connecting plate 5-3 is attached to the aluminum back plate of the third plate 3 and then connected to the third plate 3 by fasteners; and the fourth connecting plate 5-4 is attached to the aluminum back plate of the fourth plate 4 and then connected to the fourth plate 4 by fasteners. In this case, the first connecting plate 5-1 serves to support the second plate 2 and the fourth plate 4 in the vertical direction.

[0060] See Figure 5 In order to install the polyhedral composite panel, a number of mounting parts 7 are provided at both ends of the polyhedral composite panel along its length. Furthermore, the mounting parts 7 are spaced apart at both ends of the first panel 1 and the second panel 2.

[0061] See Figure 5 and Figure 8The mounting component 7 includes a groove-shaped component 7-1 and a mounting plate 7-2, the mounting plate 7-2 being flat. The groove-shaped component 7-1 includes a horizontal base plate 7-1-1 and two side plates 7-1-2 perpendicular to the two sides of the base plate. The base plate 7-1-1 is fixed to the first plate 1 or the second plate 2 by fasteners, and the mounting plate 7-2 is connected to one of the side plates 7-1-2 by fasteners. In some embodiments, the two side plates 7-1-2 can also be connected to one mounting plate 7-2 by fasteners respectively.

[0062] Furthermore, the mounting plate 7-2 is provided with through holes, which can be used for hanging or connecting to the skeleton by fasteners.

[0063] See Figure 10 For example Figure 10 In the installation configuration shown, the self-weight of the polyhedral composite panel is supported by the three-sided geometric structure formed by the first panel 1, the second panel 2, the third panel 3, and the fourth panel 4. The trapezoidal connector 5 connecting the second panel 2, the third panel 3, and the fourth panel 4 can connect these three panels at once and also provide a stable support.

[0064] When processing multi-faceted composite panels, the first panel 1, the second panel 2, the third panel 3, and the fourth panel 4 can be cut and spliced ​​according to their shapes and sizes (curved panels are molded by molds), and then trapezoidal connectors 5, corner brackets 6, and mounting parts 7 can be installed in the corresponding positions.

[0065] Alternatively, the honeycomb cores of the first plate 1, second plate 2, third plate 3, and fourth plate 4 can be cut and spliced ​​according to their shapes and sizes. Then, on a template, the surface aluminum plate and aluminum back plate are bonded and fixed on both the inner and outer sides of the honeycomb core (the surface aluminum plate and aluminum back plate need to be pre-shaped on the mold). Then, trapezoidal connectors 5, corner brackets 6, and mounting parts 7 are installed in the corresponding positions. The first method is easier to splice, but it will produce multiple splicing seams that need to be treated. The second method solves the splicing seam problem, but requires the use of a matching mold.
