Therefore, the optical fiber is the most important component of the translucent concrete. The patterns of the existing translucent concrete slabs have been fixed when they leave the factory. Replacing the pattern usually requires replacing the entire translucent concrete slab. In addition, the patterns of the translucent concrete slabs in the existing technology are all simple textures and cannot carry more information. Therefore, many shopping malls, cultural and creative parks, and squares will use large LED screens as a carrier for transmitting information, and use large LED screens to publicize to citizens. However, when the large LED screen is not powered on, it is difficult to integrate with the nearby walls, which visually destroys the integrity of the shopping malls, cultural and creative parks, and squares.

The front of the panel body has an array of openings for optical fiber column layers to pass through. The bottom of the optical fiber column layer is provided with a luminous layer. The luminous layer can emit light of different colors and illuminate the optical fiber column layer, making the top of the optical fiber column layer glow, so that the optical fiber column layer forms a luminous surface with display function. When not emitting light, the panel body is no different from an ordinary concrete panel. The bottom of the panel body is provided with a connection groove, and a signal interface is provided in the connection groove. The signal interface is connected to the luminous layer in the panel body by telecommunications, so that the video input device can be Signals are input to the light-emitting layer, and the light-emitting layer adjusts its light-emitting effect according to the content of the video input device, so that the picture displayed on the front of the board is changed. Pictures can be changed or videos can be played, which can be used for cultural creation and advertising. The board is also provided with a fixing layer for fixing the optical fiber column layer and an isolation layer for isolation. The isolation layer can cover the light-emitting layer, so that the light-emitting layer remains isolated from the concrete during and after the board is formed, ensuring the stable operation of various components inside the light-emitting layer. The rear end of the board is provided with a hanging groove for hanging the board, which is convenient for users to hang / replace the board, and has greater creative space when performing artistic design on the layout of the board.

[0006] In one embodiment, the main material of the board is a hollow board made of cast concrete. The concrete should be concrete with extremely high mechanical properties and durability. The optical fiber column layer, fixed layer, isolation layer and luminous layer are all arranged in the hollow structure of the board. Each board layer is covered with solidified concrete to ensure the stability of the internal board layer during use. The optical fiber column layer composed of multiple optical fiber columns is located at the top of the board. A single optical fiber column becomes a pixel point on the board. The multi-optical fiber column design is used to ensure that the board can provide good visual effects. , under the optical fiber column layer is a fixing layer, which is used to fix the optical fiber column so that each optical fiber column remains perpendicular to the light-emitting layer. The fixing layer is a fixing plate, that is, the optical fiber column is perpendicular to the fixing plate. The lower end of the fixed layer is an isolation layer and a light-emitting layer, wherein the isolation layer is provided with two layers, and the two isolation layers wrap the light-emitting layer so that the upper and lower sides and the sides of the light-emitting layer are isolated from the concrete. The isolation layer is composed of at least one isolation plate. The light-emitting layer is an LED light board. After power is turned on, the LED light board can emit light of corresponding color according to the input signal, so that the optical fiber column layer forms a picture.

[0007] In one embodiment, the middle parts of the fixed layer, the isolation layer and the light-emitting layer are provided with evenly arranged hollows, so that the middle parts of the above layers are in the shape of a fence, forming a mud passage for concrete to flow in. After the concrete solidifies, the above layers and the plate body are nested with each other, and the plate body formed by the concrete completely wraps each plate layer. Only the top of the optical fiber column layer is not blocked by the plate body and is flush with the top surface of the plate body. The plate body formed by the solidified concrete fastens each plate layer to ensure that the each plate layer does not shift during use. The upper end of the fixed plate is provided with a column placement groove for the insertion of the optical fiber column, so that the optical fiber column layer can form a fixed connection with the fixed layer. After insertion, the optical fiber column layer is perpendicular to the other layers, and at the same time ensures that the light source emitted can directly illuminate each optical fiber column.

[0008] In one embodiment, the light transmittance of the fixing plate is not less than 90%, ensuring that the light emitted by the luminous layer can pass through the fixing plate into the optical fiber column layer to form a high-quality image. The thickness of the fixing plate is not less than 5 mm and has a certain rigidity, which is convenient for movement and installation. The fixing plate is temperature-resistant and can maintain the stability of the fixing plate structure in an environment of -40°C to 120°C without deformation, so that it does not change when in contact with concrete, that is, the optical fiber column installed thereon is in a stable state, and the optical fiber column remains unchanged before and after the concrete solidifies. The depth of the column groove is 3.5 mm, which can effectively prevent the optical fiber column from tilting when installing the optical fiber column. The optical fiber column and the column groove are fastened by interference fit.

[0009] In one embodiment, the isolation plate is divided into isolation plate one and isolation plate two. Isolation plate one is located on the light-emitting layer, forming an upper isolation layer, and isolation plate two is located under the light-emitting layer, forming a lower isolation layer. The two layers of isolation plates can cover and protect the light-emitting layer to ensure stable transmission of current and signals. The transmittance of isolation plate one and isolation plate two is not less than 90%, and the thickness is not less than 5 mm. Both are temperature-resistant and can maintain the stability of the isolation plate structure in an environment of -40°C to 120°C without deformation, so that it does not change when in contact with concrete, that is, the light-emitting layer installed in the two isolation layers is in a stable state. The isolation layer can offset the weight of the concrete itself, prevent the light-emitting layer from being compressed, and ensure that the light-emitting layer remains unchanged before and after the concrete solidifies. A corresponding slot is provided on the side of isolation plate two close to the connection slot for the signal interface of the light-emitting layer to enter the connection slot, facilitating access to the signal line and power line.

[0010] In one embodiment, the isolation plate 1 is integrated with the fixed plate, that is, the upper fixed layer and the upper isolation layer are integrated, and the two are combined into one, which can further reduce the thickness of the plate after forming and reduce the synthesis process. Specifically, the side of the isolation plate 1 that contacts the optical fiber column is provided with a column placement groove for the optical fiber column to be placed, and the bottom of the isolation plate 1 is also provided with a horizontal bar 1 for further fastening the light-emitting layer. The horizontal bar 1 can standardize the placement position of the LED light board to ensure that the light emitted by the LED light board is evenly incident on the optical fiber column layer.

[0011] In one embodiment, the LED light board is provided with a plurality of LED light strips, and a plurality of LED lamp beads are arranged in a row on the LED light strips, and the column grooves are correspondingly arranged on each LED lamp bead, so that all the light guide fiber columns correspond to all the LED lamp beads one by one, that is, each LED lamp bead can work independently according to the input signal and emit light of different colors, so that each light guide fiber column forms a single pixel point, which can form a more complex picture. A through groove for inserting a horizontal bar is provided between two adjacent LED light strips, and each LED light strip is limited by a horizontal bar to ensure that the LED lamp beads are aligned with the light guide fiber columns.

[0012] In one embodiment, the upper surface of the isolation plate 2 is provided with a cross bar 2 that is matched with the cross bar 1. When the cross bar 1 and the cross bar 2 are attached to each other, the strip-shaped space formed by the two can completely clamp the LED light strip. At the same time, the cross bar 1 and the cross bar 2 form a supporting structure to ensure that the isolation plate 1 and the isolation plate 2 will not exert pressure on the LED light board when the LED light strip is completely clamped, and at the same time, the pressure exerted on the LED light strip by the plate body under the action of gravity can be offset. The mud passage is located in the middle of the cross bar 1 and the cross bar 2, which can effectively prevent the concrete itself or other liquids and fine particles from entering the cavity formed by the isolation plate 1 and the isolation plate 2 when the concrete is poured. The material of the fixed plate, the isolation plate 1 and the isolation plate 2 is a high-transmittance PC board, which ensures light transmittance and good imaging quality.

[0013] In one embodiment, the present application also provides a preparation method, wherein the plate body and each layer structure therein are cast in a plate forming mold, and the specific steps are as follows:

[0014] Step 1: Place the LED light board on the second isolation board, place the signal interface in the slot, place the second horizontal bar into the through slot, complete the positioning of the LED light strip, and apply glue on the four sides of the top surface of the second isolation board and the top surface of the second horizontal bar;

[0015] Step 2: Align the bottom surface of isolation board 1 with isolation board 2, and align cross bar 1 with cross bar 2 to form a cavity. The LED light strip is located in the cavity. Use glue to stick isolation board 1 and isolation board 2 together. After sticking, isolation board 1 and isolation board 2 will cover the LED light board.

[0016] Step 3: Place the optical fiber columns one by one into the column placement grooves provided on the first isolation plate, using interference fit to securely connect the optical fiber columns to the column placement grooves. After all the optical fiber columns are placed, a layer of optical fiber columns is formed and connected to the fixed layer.

[0017] Step 4: Place the hanging groove piece in the plate forming mold, place the connecting groove casting under the through groove, and support the plate layers that have been integrated together through the hanging groove piece and the connecting groove casting;

[0018] Step 5: Pour concrete. The concrete can flow down through the mud channel to the lower end of the isolation plate 2 and fill the space at the lower end of the isolation plate 2.

[0019] Step 6: Continue to pour concrete until the concrete fills the mud channel and overflows. Stop adding concrete when the overflowed concrete fills the entire slab mold.

[0020] Step 7: After the concrete solidifies, it can be disassembled into the plate mold and the connecting groove casting, and the hanging groove parts are fixed to the back of the plate body by concrete;

[0021] Step 8: Polish the surface of the formed board to make it smooth and beautiful.

[0022] Beneficial effects: When the board is not powered on, it is no different from an ordinary cement wall and can be integrated with the traditional curtain wall, with a more unified visual effect. After the board is powered on, the front of the board can light up to play pictures / videos. Compared with the existing concrete light-emitting board, it has the advantages of variable patterns and continuous playback. The fiber optic column is used as a pixel point. In order to ensure that the light is concentrated in the fiber optic column and the light in adjacent fiber optic columns does not interfere with each other, the board is provided with an opening to wrap the side wall of the fiber optic column. At the same time, the opening can further tighten the fiber optic column so that it does not shift during movement and use. There are two layers of isolation panels to cover the LED light board, so that the LED light is isolated from the outside world. At the same time, it also limits the fiber optic column, column slot, and LED lamp beads to be located in the same straight line, ensuring the stability of imaging. It has the advantages of simple installation, reliable structure, high-quality imaging, and the ability to play pictures and videos. BRIEF DESCRIPTION OF THE DRAWINGS

For example, desktop computers, laptops, mobile phones, and tablet computers can all input signals to the light-emitting layer 6 in this way. The light-emitting layer 6 adjusts the light-emitting effect of the light-emitting layer 6 according to the content of the video input device, so that the picture displayed on the front of the board 1 is changed, and the picture can be changed or the video can be played to achieve the purpose of image transmission information. The board 1 is also provided with a fixing layer 4 for fixing the optical fiber column layer 3 and an isolation layer 5 for isolation. The isolation layer 5 can cover the light-emitting layer 6.

When in use, multiple boards 1 can be hung on a shelf to form a larger visual curtain wall composed of multiple boards 1, and each board 1 cooperates in imaging.

[0050] Preferably, the board body 1 is a hollow board body 1 cast with concrete, and the optical fiber column layer 3, fixed layer 4, isolation layer 5 and light-emitting layer 6 are all arranged in the hollow structure of the board body 1. The uppermost part of the board body 1 is the optical fiber column layer 3 composed of a plurality of optical fiber columns 10. The optical fiber columns 10 are arrayed in the horizontal and vertical directions to form a multi-point matrix. A single optical fiber column 10 becomes a pixel point on the board body 1. Below the optical fiber column layer 3 is the fixed layer 4, and the fixed layer 4 is a fixed plate 11.

After solidification, the concrete of the plate body 1 will completely cover each plate layer inside it, and only the top of the optical fiber column layer 3 is exposed on the top surface of the plate body 1. At this time, the side of each optical fiber column 10 is completely wrapped by concrete, so that the light emitted by the light-emitting layer 6 is condensed in the optical fiber column 10, and the light from different optical fiber columns 10 cannot affect each other, ensuring the brightness and color accuracy of the light when a single optical fiber column 10 is used as a pixel point.

[0052] Preferably, the middle parts of the fixed layer 4, the isolation layer 5 and the light-emitting layer 6 are provided with evenly arranged hollows, so that the middle parts of the above layers are fence-shaped, forming a mud passage 14 for concrete to flow in. After the concrete solidifies, the above layers and the plate body 1 are nested with each other, and the upper end of the fixed plate 11 is provided with a column placement groove 15 for the optical fiber column 10 to be placed, so that the optical fiber column layer 3 can form a fixed connection with the fixed layer 4.

After the concrete solidifies, the concrete in the mud channel 14 and the concrete outside the side walls of each layer together form a clamping force on each plate layer. The optical fiber column 10 and the column placement groove 15 are both cylindrical, wherein the diameter of the optical fiber column 10 is 2.1 mm, and the diameter of the column placement groove 15 is 2.0 mm.

The depth of the column groove 15 is 3.5 mm, and the optical fiber column 10 and the column groove 15 are fastened by interference fit.

[0055] By adopting the above technical solutions, such as 1 to Figure 8 ; The transmittance of the fixed plate 11 is not less than 90%, and the light emitted by the LED light board 13 has a small loss after passing through the fixed plate 11, or the luminous brightness of the LED light board 13 is adjusted by reverse calculation through the loss rate to offset the light loss generated by the fixed plate 11, so that the imaging effect is accurate.

After insertion, the height protruding from the fixed plate 11 is 10mm, which is exactly level with the top surface of the plate body 1.

[0056] Preferably, the isolation plate 12 is divided into isolation plate 16 and isolation plate 2 17. The isolation plate 16 is located on the light-emitting layer 6, forming the isolation layer 5 above, and the isolation plate 2 17 is located under the light-emitting layer 6, forming the isolation layer 5 below. The transmittance of the isolation plate 16 and the isolation plate 2 17 is not less than 90%, and the thickness is not less than 5 mm. Both are temperature-resistant and can maintain the stability of the isolation plate structure without deformation in an environment of -40°C to 120°C.

The signal interface 8 on the LED light board 13 enters the connecting groove 7 from the slot 18 through the isolation plate 2 17. The connecting groove 7 is a cavity structure formed after the connecting groove casting 24 is connected to the slot 18, that is, before injecting concrete into the plate mold, the connecting groove casting 24 should be placed in the slot 18 first. At this time, the signal interface 8 is located in the cavity structure of the two.

[0058] Preferably, the isolation plate 16 is integrated with the fixing plate 11, that is, the upper fixing layer 4 and the upper isolation layer 5 are integrated.

At the same time, the column groove 15 can guide the optical fiber column 10. When inserting, you only need to press the top of the optical fiber column 10 so that its bottom slides completely into the column groove 15 to make the optical fiber column 10 perpendicular to the isolation plate 16 and the isolation plate 16.

[0060] Preferably, the LED light board 13 is provided with a plurality of LED light strips 20, and a plurality of LED lamp beads (not shown) are arranged in a row on the LED light strips 20, and the column grooves 15 are correspondingly arranged on each LED lamp bead, so that all the light guide fiber columns 10 correspond to all the LED lamp beads one by one, and a through groove 21 for the horizontal bar 19 to be placed is provided between two adjacent LED light strips 20.

The mud passage 14 is located in the middle of the cross bar 19 and the cross bar 22. The material of the fixed plate 11, the isolation plate 16 and the isolation plate 17 is a high-transmittance PC board.

[0063] By adopting the above technical solution, during the board forming process, after the isolation board 16 and the isolation board 2 17 are aligned and fitted, the guard bar 19 and the cross bar 2 22 are also fitted together, and the two form a supporting structure to maintain the space for clamping the LED light strip 20. The supporting mechanism formed by the two can offset the pressure of the upper wall of the board body 1 when the board body 1 is formed. After the board is formed, when it is hung, the solidified concrete in the mud channel 14 becomes the supporting mechanism of each half layer, so that the gravity of each internal board layer can act on the solidified concrete in the mud channel 14.

[0064] The present application also provides a method for preparing a self-imageable exterior wall concrete hanging panel, wherein the panel body 1 and its internal layer structures are cast in a panel forming mold.

The method comprises one panel forming mold, four hanging groove members 23, and one connecting groove casting 24. The specific steps are as follows:

[0065] Step 1: Place the LED light board 13 on the second isolation board 17, place the signal interface in the slot 18, place the second cross bar 22 in the through slot 21, and apply adhesive (transparent glass glue) on the four sides of the top surface of the second isolation board 17 and the top surface of the second cross bar 22;

[0066] Step 2: Align the bottom surface of isolation board 16 with isolation board 2 17, and align cross bar 19 with cross bar 2 22, and glue isolation board 16 and isolation board 2 17 together. After bonding, isolation board 16 and isolation board 2 17 will cover the LED light board 13, and the support structure during the concrete solidification process is formed.

[0067] Step 3: Place the optical fiber columns 10 one by one into the column placement grooves 15 provided on the isolation plate 16, using interference fit to securely connect the optical fiber columns 10 to the column placement grooves 15. After all optical fiber columns are placed, the optical fiber column layer 3 is formed and connected to the fixing layer 4. The specific placement method is to align the optical fiber columns 10 with the column placement grooves 15, apply pressure on the top of the optical fiber columns 10, and completely insert the optical fiber columns 10.

[0068] Step 4: Place the hanging groove member 23 in the plate forming mold, and place the connecting groove casting 24 under the through groove. After the connecting groove casting 24 is placed, a closed space is formed between the through groove. The hanging groove member 23 and the connecting groove casting 24 support the plate layers that have been integrated into one.

[0069] Step 5: Pour concrete. The concrete can flow downward through the mud channel 14 to the lower end of the isolation plate 2 17 and fill the space at the lower end of the isolation plate 2 17. The flowing concrete will form the bottom wall of the plate body 1.

[0070] Step 6: Continue pouring concrete until the concrete fills the mud channel 14 and overflows. When the overflowed concrete fills the entire slab mold, stop adding concrete.

[0071] Step 7: After the concrete solidifies, the top, bottom, and side walls of the panel 1 are formed, and the panel mold and the connecting groove casting 24 are disassembled. The hanging groove member 23 is fixed to the back of the panel 1 by the solidified concrete.

[0072] Step 8: Polish the surface of the formed plate 1 to make it smooth and beautiful.

[0073] After completing the above steps, the light emitting layer 6 should be powered on to be tested to ensure that the light emitting layer 6 works normally and the imaging effect of the board 1 is guaranteed.

[0074] Working principle: There are multiple optical fiber columns 10 in the rectangular array on the front of the board 1. Each optical fiber column 10 is provided with an LED lamp bead at the bottom, and each LED lamp bead can work independently, so that a single optical fiber column 10 acts as a pixel point, and the optical fiber column layer 3 composed of multiple optical fiber columns 10 has a display effect. The optical fiber columns 10 are wrapped by the openings 2, so that adjacent optical fiber columns 10 are isolated from each other and do not interfere with each other, thereby ensuring the imaging quality of the optical fiber column layer 3. The surface material of the board 1 is concrete. When the light-emitting layer 6 is not working, the board 1 can be integrated with the ordinary curtain wall. After power is turned on, the board 1 can be used as a TV curtain wall. It is connected to external equipment through the signal interface 8, so that each LED lamp bead in the light-emitting layer 6 emits corresponding light, so that the top surface of the optical fiber column layer 3 forms a picture / video.
