Description

Technical Field

[0001] This invention relates to the field of translucent concrete technology, specifically to a translucent concrete mold and a method for preparing translucent concrete. Background Technology

[0002] In 2001, Hungarian architect Aron Rossonc invented translucent concrete and named it "Litracon." At the 2010 Shanghai World Expo, the Italian Pavilion successfully used translucent concrete, gaining widespread attention. Since then, domestic enterprises have also continuously researched and developed it, pushing it from an experimental material to practical application.

[0003] However, existing technologies still have the following problems: Existing translucent concrete molds and preparation methods largely rely on manual operation. The injection and compaction of concrete raw materials must be done manually, which is not only labor-intensive but also difficult to control operational errors, resulting in low production efficiency. At the same time, processes such as feeding and compaction are often carried out separately, lacking integrated design, and the process transition is time-consuming, resulting in a slow overall production pace.

[0004] Secondly, existing technologies typically compact concrete raw materials from only one direction, making it difficult to ensure uniform stress on the raw materials and easily leading to insufficient density. This, in turn, affects the quality stability of translucent concrete after molding, resulting in inconsistent finished product quality.

[0005] Secondly, in terms of mobility and fixation, existing molds are either inconvenient to move and cannot flexibly adapt to the needs of different work sites; or although they can move, their fixation effect is poor, and they are prone to shaking during production. It is difficult to balance mobility and fixation, which affects the stability of production.

[0006] To address the aforementioned problems, the inventors have proposed a translucent concrete mold and a method for preparing translucent concrete. Summary of the Invention

[0007] To address the problems of high labor intensity, low production efficiency, difficulty in ensuring uniform stress on raw materials, insufficient density, and inconvenience in movement, which prevents flexible adaptation to different work sites, the present invention aims to provide a translucent concrete mold and a method for preparing translucent concrete.

[0008] To solve the above technical problems, the present invention adopts the following technical solution: a translucent concrete mold, including a support, universal wheels symmetrically provided on the lower surface of the support, a curved rod fixedly provided on one side of the support, and a push handle sleeved on the outer surface of the curved rod, a motor provided inside the support, a rotating shaft rotatably provided on the upper surface of the support, and a lower plate, a middle plate and an upper plate fixedly sleeved on the outer surface of the rotating shaft, a feeding hopper fixedly provided on the upper surface of the support, a screw conveyor fixedly provided on the lower surface of the feeding hopper, and a discharge hopper connected to the lower surface of the screw conveyor, a turntable fixedly provided on the upper side of the support, a control panel provided on one side of the support, uprights symmetrically fixedly provided on the upper parts of both sides of the support, and support blocks clamped on the upper surface of the uprights, a rotating column rotatably provided between the two support blocks, the turntable fixedly sleeved on the outer surface of the rotating column, side guard plates fixedly provided on the upper surface of the support, and the two sides of the uprights fixedly connected to the corresponding side guard plates.

[0009] Preferably, the output end of the motor is fixedly connected to a drive shaft, a driven shaft is rotatably provided inside the bracket, and a transmission belt is sleeved on the outer surfaces of the driven shaft and the drive shaft together. The lower end of the rotating shaft passes through the bracket and is fixedly connected to the driven shaft.

[0010] Preferably, a plurality of mold pillars are inserted into the intermediate plate, and mold grooves are formed on the upper surface of the mold pillars. A plurality of upper pressing molds are passed through the upper surface of the upper plate, and upper rollers are rotatably provided on the upper side of the upper pressing molds, and the upper rollers are used in conjunction with the turntable. A pressing block is fixedly provided at the lower end of the upper pressing molds to cooperate with the mold grooves. A plurality of lower pressing molds are passed through the upper surface of the lower plate, and lower rollers are rotatably provided at the lower end of the lower pressing molds. A plurality of arc-shaped blocks are fixedly provided on the upper surface of the bracket, and the arc-shaped blocks are used in conjunction with the lower rollers.

[0011] Preferably, L-shaped plates are symmetrically fixed on both sides of the bracket, a stud is threaded through the upper side of the L-shaped plate, a contact plate is provided at the lower end of the stud, a wheel is fixed at the upper end of the stud, a handle is rotatably provided on the upper surface of the wheel, reinforcing plates are symmetrically fixed on the L-shaped plate, and a groove for cooperating with the stud is opened on the upper surface of the contact plate.

[0012] A method for preparing translucent concrete using a translucent concrete mold includes the following steps: S1. Raw Material Preparation and Mixing: Select high-strength cement, well-graded fine aggregate (such as quartz sand), high-transmittance optical fibers or resin rods, and standard mixing water according to the specified proportions. First, dry-mix the cement and fine aggregate in a mixing device for 1-2 minutes to ensure uniform mixing. Then, add the pre-proportioned water and continue mixing for 3-5 minutes to form a basic cement paste. Subsequently, slowly add the translucent material cut to the appropriate length to the paste while stirring continuously to ensure that the translucent material is evenly distributed in the paste without significant agglomeration. This results in a uniform and fluid concrete mixture, providing a good material foundation for subsequent molding.

[0013] S2. Mold Operation and Raw Material Forming: Before starting the device, check that all components are functioning properly, ensuring the mold pillar is securely inserted into the intermediate plate and that the mold slot is clean and free of debris. Start the device via the control panel; the motor will begin working, driving the drive shaft to rotate. The drive shaft transmits power to the driven shaft via a transmission belt, which in turn drives the rotating shaft, causing the lower, intermediate, and upper plates to rotate synchronously and smoothly. Slowly pour the well-mixed material into the feeding hopper. Under the influence of gravity and the pushing action of the screw conveyor, the mixture is precisely injected into the mold slot of the mold pillar on the intermediate plate through the discharge hopper. During the discharge process, the speed of the screw conveyor can be adjusted via the control panel to control the feeding speed and prevent material overflow or insufficient feeding. As the upper platen rotates, the upper die on it moves synchronously. When the upper roller on the upper side of the upper die contacts the turntable fixed on the outer surface of the rotating column, the turntable exerts downward pressure on the upper roller, causing the upper die to move downward. This causes the lower block of the upper die to slowly press into the mold groove, thus initially compacting the concrete material. At the same time, the lower platen rotates with the rotating shaft, and the lower die on it moves synchronously. When the lower roller at the lower end of the lower die contacts the arc-shaped block fixed on the upper surface of the support, the arc-shaped block exerts an upward thrust on the lower roller, causing the lower die to move upward. This performs secondary compaction of the concrete material in the mold groove from below. Through bidirectional compaction, the material is tightly bound together, reducing internal porosity.

[0014] S3. Finished Product Removal and Curing: After the concrete has initially solidified in the mold slot (usually 4-6 hours, the specific time may vary depending on the ambient temperature and mix proportions), and the surface has lost its fluidity and gained a certain strength, close the device via the control panel. Carefully remove the mold column from the central platen, avoiding excessive force that could damage the finished product. Then, remove the molded translucent concrete product from the mold slot. Place the removed product in a curing chamber, maintaining the temperature at 20±2℃ and the relative humidity above 90%, for at least 7 days. During the curing process, regularly check the surface of the product for dryness, and spray water to maintain moisture if necessary, preventing cracks caused by rapid water loss and ensuring a stable improvement in its strength and translucency.

[0015] S4. Finished Product Inspection and Finishing: After curing, the translucent concrete products undergo performance testing. First, observe the surface for smoothness, cracks, pitting, or other defects. Then, use a light transmittance meter to test the light transmittance and a pressure testing machine to test the compressive strength, ensuring all indicators meet design requirements. For products with minor surface defects, use specialized repair materials to repair and polish them to achieve a smooth surface. For products that fail the tests, analyze the causes and take corrective action. If the issue is due to raw material ratio problems, adjust the raw material proportions and re-prepare the product. If the issue is due to insufficient compaction, check and adjust the relevant mold components. After inspection and finishing, a qualified translucent concrete finished product is obtained.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention achieves automatic injection and compaction of concrete raw materials through mechanized operation, which greatly improves production efficiency and reduces the intensity and error of manual operation. The device integrates functions such as feeding and compaction. The integrated design makes the production process more coherent, reduces the conversion time between processes, and improves the overall production rhythm.

[0017] 2. This invention uses the combination of a turntable and an upper roller, and an arc-shaped block and a lower roller to compact the concrete raw materials from both the top and bottom, ensuring the density and quality stability of the concrete molding and improving the finished quality of translucent concrete.

[0018] 3. The present invention is equipped with casters, which facilitate flexible movement and adapt to different work site requirements; at the same time, the combination of studs and contact plates can achieve stable fixation, ensuring the stability of the device during the production process, thus taking into account both mobility and fixation.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example: Figure 1-3As shown, the present invention provides a translucent concrete mold, including a support 1. Universal wheels 11 are symmetrically arranged on the lower surface of the support 1. A curved rod 7 is fixedly arranged on one side of the support 1, and a push handle 71 is sleeved on the outer surface of the curved rod 7. A motor 2 is installed inside the support 1. A rotating shaft 24 is rotatably arranged on the upper surface of the support 1, and a lower plate 37, a middle plate 3, and an upper plate 33 are fixedly sleeved on the outer surface of the rotating shaft 24. A feeding hopper 4 is fixedly arranged on the upper surface of the support 1. A screw conveyor 41 is fixedly arranged on the lower surface of the feeding hopper 4, and a discharge hopper 42 is connected to the lower surface of the screw conveyor 41. A turntable 5 is fixedly arranged on the upper side of the support 1. A control panel 6 is provided on one side of the support 1. Uprights 51 are symmetrically fixed on the upper parts of both sides of the support 1, and the upper part of the uprights 51... The surface is fitted with a support block 52, and a rotating column 53 is rotatably mounted between the two support blocks 52. The turntable 5 is fixedly fitted on the outer surface of the rotating column 53. The upper surface of the support 1 is fixedly fitted with a side guard plate 12. The two sides of the upright 51 are fixedly connected to the corresponding side guard plates 12. During the operation of the mold, concrete raw materials need to be added through the feeding hopper 4. The raw materials enter the screw conveyor 41 through the feeding hopper 4. The screw conveyor 41 conveys the raw materials to the discharge hopper 42. Then, the discharge hopper 42 accurately injects the raw materials into the mold groove 32 of the mold column 31 on the intermediate plate 3. The operation of the entire device can be controlled by the control panel 6 on one side of the support 1. The side guard plate 12 plays a role in fixing and protecting the upright 51. The support block 52 on the upright 51 is used to support the rotating column 53.

[0031] Preferably, the output end of the motor 2 is fixedly connected to the drive shaft 21, and the driven shaft 23 is rotatably provided inside the bracket 1. The outer surfaces of the driven shaft 23 and the drive shaft 21 are jointly sleeved with a transmission belt 22. The lower end of the rotating shaft 24 passes through the bracket 1 and is fixedly connected to the driven shaft 23. The operation of the translucent concrete mold is powered by the motor 2. After the motor 2 is started, the output end drives the drive shaft 21 to rotate. The drive shaft 21 transmits power to the driven shaft 23 through the transmission belt 22, so that the driven shaft 23 rotates synchronously, thereby driving the rotating shaft 24 fixedly connected to the driven shaft 23 to rotate. The rotation of the rotating shaft 24 will drive the lower plate 37, the middle plate 3 and the upper plate 33 fixedly sleeved on its outer surface to rotate together.

[0032] Preferably, a plurality of mold pillars 31 are inserted into the intermediate platen 3, and mold grooves 32 are formed on the upper surface of the mold pillars 31. A plurality of upper pressing molds 34 are passed through the upper surface of the upper platen 33. An upper roller 35 is rotatably mounted on the upper side of the upper pressing mold 34, and the upper roller 35 is used in conjunction with the turntable 5. A pressing block 36 is fixedly mounted on the lower end of the upper pressing mold 34 to cooperate with the mold groove 32. A plurality of lower pressing molds 39 are passed through the upper surface of the lower platen 37, and a lower roller 38 is rotatably mounted on the lower end of the lower pressing mold 39. A plurality of arc-shaped blocks 310 are fixedly mounted on the upper surface of the bracket 1, and the arc-shaped blocks 310 are used in conjunction with the lower roller 38. As the upper platen 33 rotates, the upper pressing molds on the upper platen 33... 34 moves synchronously. The upper roller 35 on the upper side of the upper mold 34 contacts the turntable 5 fixed on the outer surface of the rotating column 53. The turntable 5 exerts downward pressure on the upper roller 35, causing the upper mold 34 to move downward, so that the pressure block 36 at the lower end of the upper mold 34 is pressed into the mold groove 32 to compact the concrete material. At the same time, when the lower platen 37 rotates with the rotating shaft 24, the lower mold 39 on the lower platen 37 moves synchronously. The lower roller 38 at the lower end of the lower mold 39 contacts the arc-shaped block 310 fixed on the upper surface of the bracket 1. The arc-shaped block 310 exerts an upward thrust on the lower roller 38, causing the lower mold 39 to move upward, assisting in compacting the concrete material in the mold groove 32 from below.

[0033] Preferably, L-shaped plates 8 are symmetrically fixed on both sides of the bracket 1. A stud 81 is threaded through the upper side of the L-shaped plate 8. A contact plate 82 is provided at the lower end of the stud 81. A rotating wheel 83 is fixed at the upper end of the stud 81. A handle 84 is rotatably provided on the upper surface of the rotating wheel 83. A reinforcing plate 85 is symmetrically fixed on the L-shaped plate 8. A groove 86 for use with the stud 81 is opened on the upper surface of the contact plate 82. The movement of the device can be achieved by pushing the push handle 71 on the crank 7 and by using the universal wheels 11 on the lower surface of the bracket 1 for flexible movement. When it is necessary to fix the device, rotate the handle 84 of the stud 81 on the L-shaped plate 8 to make the rotating wheel 83 drive the stud 81 to move downward until the contact plate 82 is in close contact with the ground. The reinforcing plate 85 enhances the structural stability of the L-shaped plate 8, and the groove 86 ensures the stability of the connection between the stud 81 and the contact plate 82.

[0034] A method for preparing translucent concrete using a translucent concrete mold includes the following steps: S1. Raw Material Preparation and Mixing: Select high-strength cement, well-graded fine aggregate (such as quartz sand), high-transmittance optical fibers or resin rods, and standard mixing water according to the specified proportions. First, dry-mix the cement and fine aggregate in a mixing device for 1-2 minutes to ensure uniform mixing. Then, add the pre-proportioned water and continue mixing for 3-5 minutes to form a basic cement paste. Subsequently, slowly add the translucent material cut to the appropriate length to the paste while stirring continuously to ensure that the translucent material is evenly distributed in the paste without significant agglomeration. This results in a uniform and fluid concrete mixture, providing a good material foundation for subsequent molding.

[0035] S2. Mold Operation and Raw Material Forming: Before starting the device, check that all components are functioning properly, ensuring the mold pillar is securely inserted into the intermediate plate and that the mold slot is clean and free of debris. Start the device via the control panel; the motor will begin working, driving the drive shaft to rotate. The drive shaft transmits power to the driven shaft via a transmission belt, which in turn drives the rotating shaft, causing the lower, intermediate, and upper plates to rotate synchronously and smoothly. Slowly pour the well-mixed material into the feeding hopper. Under the influence of gravity and the pushing action of the screw conveyor, the mixture is precisely injected into the mold slot of the mold pillar on the intermediate plate through the discharge hopper. During the discharge process, the speed of the screw conveyor can be adjusted via the control panel to control the feeding speed and prevent material overflow or insufficient feeding. As the upper platen rotates, the upper die on it moves synchronously. When the upper roller on the upper side of the upper die contacts the turntable fixed on the outer surface of the rotating column, the turntable exerts downward pressure on the upper roller, causing the upper die to move downward. This causes the lower block of the upper die to slowly press into the mold groove, thus initially compacting the concrete material. At the same time, the lower platen rotates with the rotating shaft, and the lower die on it moves synchronously. When the lower roller at the lower end of the lower die contacts the arc-shaped block fixed on the upper surface of the support, the arc-shaped block exerts an upward thrust on the lower roller, causing the lower die to move upward. This performs secondary compaction of the concrete material in the mold groove from below. Through bidirectional compaction, the material is tightly bound together, reducing internal porosity.

[0036] S3. Finished Product Removal and Curing: After the concrete has initially solidified in the mold slot (usually 4-6 hours, the specific time may vary depending on the ambient temperature and mix proportions), and the surface has lost its fluidity and gained a certain strength, close the device via the control panel. Carefully remove the mold column from the central platen, avoiding excessive force that could damage the finished product. Then, remove the molded translucent concrete product from the mold slot. Place the removed product in a curing chamber, maintaining the temperature at 20±2℃ and the relative humidity above 90%, for at least 7 days. During the curing process, regularly check the surface of the product for dryness, and spray water to maintain moisture if necessary, preventing cracks caused by rapid water loss and ensuring a stable improvement in its strength and translucency.

[0037] S4. Finished Product Inspection and Finishing: After curing, the translucent concrete products undergo performance testing. First, observe the surface for smoothness, cracks, pitting, or other defects. Then, use a light transmittance meter to test the light transmittance and a pressure testing machine to test the compressive strength, ensuring all indicators meet design requirements. For products with minor surface defects, use specialized repair materials to repair and polish them to achieve a smooth surface. For products that fail the tests, analyze the causes and take corrective action. If the issue is due to raw material ratio problems, adjust the raw material proportions and re-prepare the product. If the issue is due to insufficient compaction, check and adjust the relevant mold components. After inspection and finishing, a qualified translucent concrete finished product is obtained.

[0038] Working principle: The operation of this translucent concrete mold is powered by motor 2. After motor 2 starts, the output end drives the drive shaft 21 to rotate. The drive shaft 21 transmits power to the driven shaft 23 through the transmission belt 22, so that the driven shaft 23 rotates synchronously, which in turn drives the rotating shaft 24 fixedly connected to the driven shaft 23 to rotate. The rotation of the rotating shaft 24 will drive the lower plate 37, the middle plate 3 and the upper plate 33 fixedly sleeved on its outer surface to rotate together. During the mold operation, concrete raw materials need to be added through the feeding hopper 4. The raw materials enter the screw conveyor 41 through the feeding hopper 4. The screw conveyor 41 transports the raw materials to the discharge hopper 42, and then the discharge hopper 42 accurately injects the raw materials into the mold groove 32 of the mold column 31 on the intermediate plate 3. As the upper platen 33 rotates, the upper pressure mold 34 on the upper platen 33 moves synchronously. The upper roller 35 on the upper side of the upper pressure mold 34 contacts the turntable 5 fixed on the outer surface of the rotating column 53. The turntable 5 exerts downward pressure on the upper roller 35, which drives the upper pressure mold 34 to move downward, so that the pressure block 36 at the lower end of the upper pressure mold 34 is pressed into the mold groove 32 to compact the concrete raw material. At the same time, when the lower platen 37 rotates with the rotating shaft 24, the lower pressing mold 39 on the lower platen 37 moves synchronously. The lower roller 38 at the lower end of the lower pressing mold 39 contacts the arc block 310 fixed on the upper surface of the bracket 1. The arc block 310 generates an upward thrust on the lower roller 38, which drives the lower pressing mold 39 to move upward, and assists in compacting the concrete material in the mold groove 32 from below. The device can be moved by pushing the handle 71 on the crank 7, and can be moved flexibly using the casters 11 on the lower surface of the bracket 1. When it is necessary to fix the device, rotate the handle 84 on the stud 81 on the L-shaped plate 8, so that the rotating wheel 83 drives the stud 81 to move downward until the contact plate 82 is in close contact with the ground. The reinforcing plate 85 enhances the structural stability of the L-shaped plate 8, and the column groove 86 ensures the stability of the connection between the stud 81 and the contact plate 82. The operation of the entire device can be controlled by the control panel 6 on one side of the bracket 1. The side guard plate 12 fixes and protects the upright 51, and the support block 52 on the upright 51 supports the rotating column 53.

[0039] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.

When the upper roller on the upper side of the upper die contacts the turntable fixed on the outer surface of the rotating column, the turntable exerts downward pressure on the upper roller, causing the upper die to move downward. This allows the lower block of the upper die to be slowly pressed into the mold groove, initially compacting the concrete material. Simultaneously, the lower platen rotates with the rotating shaft, and the lower die on it moves synchronously. When the lower roller at the lower end of the lower die contacts the arc-shaped block fixed on the upper surface of the support, the arc-shaped block exerts upward thrust on the lower roller, causing the lower die to move upward. This provides secondary compaction of the concrete material in the mold groove from below. Through bidirectional compaction, the material is tightly bound together, reducing internal porosity. S3. Finished Product Removal and Curing: After the concrete has initially solidified in the mold groove (usually 4-6 hours, the specific time may vary depending on the ambient temperature and mix ratio), and the surface has lost its fluidity and gained a certain strength, close the device via the control panel. Carefully remove the mold column from the central plate, avoiding excessive force that could damage the finished product. Then, remove the formed translucent concrete product from the mold groove. Place the removed product in a curing room, maintaining the temperature at 20±2℃ and the relative humidity above 90%, for at least 7 days. During the curing process, regularly check the surface of the product for dryness, and spray water to keep it moist if necessary, preventing cracks caused by rapid water loss and ensuring a stable improvement in its strength and translucency. S4. Finished Product Inspection and Finishing: After curing, the translucent concrete products undergo performance testing. First, observe the surface for smoothness, cracks, pitting, or other defects. Then, use a light transmittance meter to measure the light transmittance and a pressure testing machine to test the compressive strength, ensuring all indicators meet design requirements. For products with minor surface defects, use specialized repair materials to repair and polish them to achieve a smooth surface. For products that fail the tests, analyze the causes and take corrective action. If the issue stems from raw material ratio problems, adjust the raw material proportions and re-prepare the product. If the compaction is insufficient, the relevant components of the mold need to be inspected and adjusted. After inspection and repair, a qualified translucent concrete product is obtained.
