Description

Technical Field

[0001] The invention relates to the field of building materials, in particular to a GRC-LED hyperbolic light-emitting decorative plate and a manufacturing method thereof. Background Art

[0002] Media architecture refers to a new architectural form that emerged after 2000, which combines digital images with the exterior of the building, turning the exterior of the building into a large screen or an architectural shape that can play digital images.

[0003] Under current circumstances, LED screens are usually used as a media device, becoming black gates hung on the facade of buildings, or LED light grids are temporarily hung on the facade of buildings. They are only used as temporary facilities of buildings, which are not only expensive, but also unsightly and pose safety hazards.

[0004] Therefore, the present application proposes a GRC-LED hyperbolic luminous decorative panel that can embody the dual functions of building panels and LED light-emitting devices, thereby changing the singleness of the functions of building wall materials and also changing the fact that most of such related products are flat in shape and difficult to meet the needs of hyperbolic building shapes. Summary of the invention

[0005] The purpose of the present invention is to provide a GRC-LED hyperbolic luminous decorative plate and a manufacturing method thereof, so as to solve the technical problem that the building wall material has a single function and cannot meet the requirements of the hyperbolic luminous wall architectural shape.

[0006] Technical solution: GRC-LED hyperbolic luminous decorative panel, including a hyperbolic panel and an LED light emitting device embedded in the hyperbolic panel, wherein the LED light emitting device includes a flexible leather wire light strip, a plurality of LED lamp beads distributed on the flexible leather wire light strip, and a light guide lamp post connected to the LED lamp beads, wherein one end of the light guide lamp post away from the LED lamp beads extends outward until it is exposed on the surface of the hyperbolic panel;

[0007] The flexible leather light strip is embedded in the hyperbolic panel in the shape of a curved surface of the hyperbolic panel.

[0008] The hyperbolic surface panel adopts a composite reinforced cement base material.

[0009] In a specific possible implementation manner, the LED lamp lighting device further includes a power line and a light source control line connected to the flexible leather wire light strip, and the other ends of the power line and the light source control line extend to the outside of the hyperbolic panel.

[0010] Through the above technical solution, the connecting ends of the power line and the light source control line can be easily connected to other hyperbolic luminous decorative panels, or to external power supplies and control devices to realize the image luminous function.

[0011] In a specific possible implementation manner, the outer surface of the LED lamp bead is sealed.

[0012] Through the above technical solution, a protective layer is formed on the outer surface of the LED lamp bead to prevent the external environment from affecting the performance of the LED lamp bead, thereby improving the seismic resistance and service life of the LED lamp bead.

[0013] The manufacturing method of the GRC-LED hyperbolic light-emitting decorative plate comprises the following steps:

[0014] Step 1: According to the requirements of the hyperbolic luminous decorative panel, the spatial position of the LED light-emitting device is arranged on the hyperbolic mold according to the design requirements and fixed;

[0015] Step 2: Prepare GRC slurry by mixing cement, glass fiber, admixture and water in proportion, and pour it onto the mold surface of the hyperbolic surface;

[0016] Step 3: Use a molding tool to flatten and compact the GRC slurry and fit it tightly with the LED light-emitting device, remove bubbles, and allow the GRC slurry to fully impregnate the LED light-emitting device;

[0017] Step 4: Curing for 1-3 days, demoulding, and forming a semi-finished product of a GRC-LED hyperbolic luminous decorative panel;

[0018] Step 5: Modify the cement-based surface of the semi-finished GRC-LED hyperboloid light-emitting decorative panel;

[0019] Step 6: Debug and test the LED light-emitting device. After reaching the designed parameters, package the finished product and put it into storage.

[0020] In a specific possible implementation method, the flexible leather wire lamp is fixed on the hyperbolic mold with a flexible grid, and one end of the light guide lamp post is fitted with the surface of the hyperbolic mold, so that each light guide lamp post is accurately positioned according to the design requirements.

[0021] Through the above technical solution, the light guide lamp column after casting and demoulding can be on the same surface as the outer surface of the GRC-LED hyperbolic decorative plate, ensuring the light-emitting function of the LED lamp.

[0022] In a specific possible implementation manner, the thickness of the GRC-LED hyperbolic light-emitting decorative plate is 10-70 mm.

[0023] Through the above technical solution, sufficient structural strength is provided and the lighting effect is kept unaffected by the thickness of the panel.

[0024] In a specific embodiment, the GRC slurry consists of the following formula:

[0025] Cement: quartz sand = 1:1~1.5,

[0026] Acrylic emulsion: mortar ratio 8%, of which the solid content of the emulsion mortar is 50%,

[0027] Fiber solid content: 1.5% to 4.5%,

[0028] Water: ash ratio 28% to 35%,

[0029] Water reducing agent: 0.006%~0.008%,

[0030] Kaolin: 0.04%~0.06%.

[0031] Through the above technical solution, the strength of the hyperbolic luminous decorative panel is improved and its service life is increased.

[0032] The beneficial effect is that the present invention fixes the LED light-emitting device in the hyperbolic mold, fits one end of the light-guiding lamp post in the LED light-emitting device to the surface of the hyperbolic mold, and casts the GRC slurry to cover it. In the hyperbolic panel, after demoulding, the light guide lamp post is exposed on the surface of the decorative board, and the control system enables the LED light-emitting device to dynamically display text data, graphic patterns, and video image effects, truly combining the digital imaging function with the hyperbolic outer skin function of the building; the present invention realizes the dual functions of decorative panel and light-emitting effect, has rich hyperbolic shape, and outstanding decorative effect, and is particularly suitable for commercial buildings, cultural venues, road traffic, cultural and tourism facilities, and urban renewal and reconstruction projects, with a wide range of applications.

[0035] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present invention. However, it is apparent to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0036] The GRC-LED hyperbolic light-emitting decorative panel in the present application document includes a hyperbolic panel 4 and an LED light-emitting device embedded in the hyperbolic panel 4. The LED light-emitting device includes a flexible leather wire light strip 1, a plurality of LED lamp beads 2 distributed on the flexible leather wire light strip 1, and a group of light guide lamp posts 3 arranged on the periphery of the LED lamp beads 2. One end of the light guide lamp post 3 is fixed on the LED lamp beads 2 of the flexible leather wire light strip, and the other end extends to the surface of the hyperbolic panel 4 to achieve a uniform light guiding effect. The flexible leather wire light strip 1 has the same curved shape as the hyperbolic panel 4, and is embedded in the hyperbolic panel 4, so that it is highly consistent with the curved surface features of the hyperbolic panel 4. The hyperbolic panel 4 is made of a cement base material, which can ensure its structural strength and durability.

[0037] In this embodiment, the LED lamp lighting device also includes a power cord and a light source control cord, one end of the power cord and the light source control cord are connected to the flexible leather wire light strip 1, and the other end extends to the outside of the hyperbolic panel 4, so that the LED lamp bead 2 is connected to the external power supply and control system through the power cord and the light source control cord, and the LED lamp lighting device is dynamically controlled by the external system to achieve the display of text, graphics, video and other effects; at the same time, it is connected to other panel terminals as a whole and connected to the external power supply and control equipment.

[0038] In this embodiment, the outer surface of the LED lamp bead 2 is sealed by using materials such as epoxy resin to encapsulate the outer surface of the LED lamp bead 2 to form a protective layer to prevent external factors such as moisture and dust from corroding the LED lamp bead 2, thereby extending the service life of the LED lamp bead 2 and improving the seismic resistance of the lamp bead.

[0039] In this embodiment, the thickness of the hyperbolic panel 4 is 10-70 mm, which can provide sufficient structural strength and keep the lighting effect unaffected by the thickness of the panel.

[0040] like Figure 1 As shown, the manufacturing method based on the above-mentioned GRC-LED hyperbolic light-emitting decorative plate includes the following steps:

[0041] Step 1, arrangement of LED light-emitting device: according to the design requirements of the decorative panel, install and fix the flexible leather light strip 1 and the LED light-emitting device thereon in the hyperbolic mold 5, ensure that it is consistent with the shape of the hyperbolic mold 5, and fix the position of the light guide lamp post 3.

[0042] Step 2, preparation and pouring of GRC slurry: Cement, quartz sand, admixture and water are prepared into GRC slurry in proportion. The addition of acrylic emulsion and fiber in the slurry can increase its flexibility and strength. The GRC slurry is cast into the hyperbolic mold 5, and is flattened and compacted with a molding tool to ensure that the GRC slurry fits tightly with the LED light-emitting device.

[0043] Step 3, curing and demoulding: After GRC casting, it is cured for 1-3 days to ensure that it is fully cured, and then demoulding is performed to form a semi-finished GRC-LED hyperboloid luminous decorative panel;

[0044] Step 4: Subsequent processing and testing: The semi-finished product is modified to make its surface smooth and tidy, and the embedded LED light-emitting device is debugged and tested to ensure that its lighting effect and display function meet the design requirements.

[0045] Step 5: Finished product packaging and storage: After testing, the finished products are packaged and stored to ensure that they are not damaged during transportation and installation.

[0046] In order to make the panel have better strength and service life, the above GRC slurry adopts the following formula:

[0047] Cement: quartz sand = 1:1~1.5,

[0048] Acrylic emulsion: mortar ratio 8%, of which the solid content of the emulsion mortar is 50%,

[0049] Fiber solid content: 1.5% to 4.5%,

[0050] Water: ash ratio 28% to 35%,

[0051] Water reducing agent: 0.006%~0.008%,

[0052] Kaolin: 0.04%~0.06%.

[0053] In this embodiment, the flexible leather light strip 1 is fixed on the hyperbolic mold 5, and one end of the light guide pole 3 is fitted with the surface of the hyperbolic mold, thereby ensuring that the light guide pole 3 is flush with the outer surface of the hyperbolic decorative panel after demoulding, thereby improving the overall aesthetics.

[0054] The implementation scheme of the present invention can organically combine the LED light-emitting device with the GRC decorative panel to achieve dual-functional composite of the building facade, so that it has both wall effect and dynamic light and shadow display function, which is particularly suitable for application scenarios with complex hyperbolic building shapes. At the same time, through reasonable material ratio, the strength and service life of the GRC-LED hyperbolic light-emitting decorative panel are greatly improved, and it can adapt to different environmental conditions and application scenarios.

[0055] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes may be made to it in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims.
