[0012] In a possible design, the two grooves are internally clamped with a same bottom plate, the bottom plate is used in conjunction with a limit clamping rod, the height of the bottom plate is greater than the depth of the groove, and one side of the bottom plate is in conflict with one side of the sandstone sound absorbing board body.

[0013] In a possible design, two symmetrically arranged thread grooves are provided inside the mounting plate, and fixing bolts penetrate the internal threads of the thread grooves.

[0014] In a possible design, a side block is fixedly connected to one side of the side panel, and one side of the side block contacts one side of the sandstone sound-absorbing panel body.

[0016] The method for making a light-transmitting sandstone sound-absorbing board specifically comprises the following steps:

[0017] S11. Making the original mold of the transparent sandstone sound-absorbing board substrate: first make an electronic drawing on the computer, use a CNC engraving machine to drill holes in the synthetic medium-density fiberboard or steel plate to obtain the original mold required by the drawing;

[0018] S12, reshaping the mold with liquid silicone to obtain a flexible silicone mold;

[0019] S13, placing the flexible silicone mold into a synthetic medium fiberboard mold with the same inner cavity size as the flexible silicone mold, with the surrounding edge of the mold higher than the flexible silicone mold, and manually inserting the PMMA optical fiber into the hole of the silicone mold;

[0020] S14, preparing quartz sand polymer gelling material;

[0021] S15, the medium quartz sand polymer gelling material is manually poured into a mold, heated and formed in a constant temperature oven, cooled and naturally cured after being taken out of the oven, demoulded when the target strength is reached, and cut, grinded and polished to become a translucent sandstone sound-absorbing board;

[0022] S16, translucent sandstone sound-absorbing board is 8mm-30mm thick board, one end of the optical fiber is flush with the front of the sandstone sound-absorbing board, and the other end is flush with the back of the sandstone sound-absorbing board. The optical fiber runs through the front and back of the sandstone sound-absorbing board to play a role in light conduction. Through the point distribution combination of light control points, it can be customized to produce various translucent patterns or texts;

[0023] S2. Select quartz sand with a particle diameter of 0.2-3 mm, add mineral pigment, anti-crack fiber and light aggregate and mix with cementitious material until mixed evenly, wherein the weight ratio of quartz sand, cementitious material, anti-crack fiber and light aggregate is 1:0.12:0.01:0.1, and stir evenly with an electric mixer;

[0024] S3. After pouring, the quartz sand polymer cementitious material is heated in a constant temperature oven for 1 hour to form, and then cooled and naturally cured for 2 days after being taken out of the oven to make its compressive strength reach more than 8MPa.

[0025] In this application, the light source assembly is installed in the cavity between the light-transmitting sandstone sound-absorbing board and the structural wall. The light source assembly illuminates the back of the light-transmitting sandstone sound-absorbing board. The optical fiber guides the light emitted by the light source assembly outward. The light will pass through the optical fiber to the front of the light-transmitting sandstone sound-absorbing board, making the surface of the light-transmitting sandstone sound-absorbing board present a point-like light effect. In this way, the light transmission function is realized. When the device is installed on one side of the wall, the light source assembly uses a lighting lamp. When the device is installed on one side of the steel structure, the light source assembly uses natural light.

[0026] When the sandstone sound-absorbing board body needs to be disassembled, the bottom plate is pushed from the bottom first. At this time, the bottom plate moves up and moves out from the inside of the groove. The bottom plate no longer blocks the back of the sandstone sound-absorbing board body and no longer blocks one end of the limit clamping rod. At this time, the limit clamping rod and the sliding block move laterally under the tension of the tension spring. The sliding block and the limit clamping rod move out from the inside of the rectangular hole, and one end of the limit clamping rod is no longer located below the blocking block;

[0027] At this time, the adjusting bolt can be rotated, and the adjusting bolt drives the block to move downward, and the block drives the sliding plate to move downward until the block completely enters the interior of the rectangular hole. At this time, there is no obstruction on both sides of the bottom of the sandstone sound-absorbing board body, and the block no longer blocks the L-shaped plug-in block. The side panels are moved horizontally, and the two side panels drive the two L-shaped plug-in blocks to be pulled out from the inside of the slot, and the side blocks no longer block the top side of the sandstone sound-absorbing board body. At this time, there is no obstruction on the side, front and back of the sandstone sound-absorbing board body, and the sandstone sound-absorbing board body can be disassembled for replacement or maintenance of the rear light source assembly. In addition, it is difficult for ordinary people to open the device without knowing the internal structure, thereby preventing the device from being accidentally touched, thereby improving safety.

[0028] Beneficial effects: Multifunctionality: The light-transmitting sandstone sound-absorbing board of the present application not only has the sound-absorbing function of the traditional sound-absorbing board, but also realizes the light-transmitting function through the built-in light source component and optical fiber, so that the sound-absorbing board can not only provide good sound-absorbing effect, but also emit soft light, creating a warm and comfortable space atmosphere. This design meets the dual needs of modern architecture for aesthetics and functionality.

[0029] Easy installation: The translucent sandstone sound-absorbing board of the present application is conveniently fixed and disassembled through the first fixing component and the second fixing component. The first fixing component can firmly fix the side of the sound-absorbing board through the design of the L-shaped plug block and the side plate; the second fixing component can conveniently control the front fixing and disassembly of the sound-absorbing board through the design of the adjustment bolt and the block. In addition, the design of the control component can further simplify the disassembly process and improve the construction efficiency.

[0030] Easy maintenance: Since the light-transmitting sandstone sound-absorbing panel of the present application adopts a convenient disassembly design, when the sound-absorbing panel needs to be replaced or the rear light source assembly needs to be repaired, the original installation structure does not need to be destroyed, thus reducing the maintenance cost and difficulty. At the same time, this design also facilitates users to replace or upgrade the sound-absorbing panel without damaging the wall or steel structure.

[0031] High safety: During the disassembly process of the translucent sandstone sound-absorbing panel of the present application, it is necessary to unlock the fixing components by pushing the bottom plate, pulling the limit lever, etc. This design avoids the risk of the device being accidentally touched and improves safety.

[0032] Customized service: The translucent sandstone sound-absorbing panel of the present application can be customized according to the needs of users. For example, by controlling the point distribution combination of optical fibers, various translucent patterns or texts can be customized to meet the user's needs for aesthetics and personalization.

[0033] This translucent sandstone sound-absorbing board has a light-transmitting function. It can be customized according to the pattern requirements, and can also be used to form various texts through the point distribution of optical fibers. For example, it can be used in the sound barrier of the highway or the facade decoration on both sides of the tunnel. It can not only reduce noise, but also form propaganda texts and patterns for safe driving through the multi-point combination of optical fibers, which plays a warning propaganda, traffic flow guidance and beautification effect. It can also be used in urban public underground passages, lecture halls, libraries, and other public interior decorations. BRIEF DESCRIPTION OF THE DRAWINGS
