Description

Technical Field

[0001] The invention relates to the field of building materials, and more particularly to a method for producing an ultra-high performance concrete tile. Background Art

[0002] Ultra-high performance concrete refers to a fiber-reinforced cement-based composite material with ultra-high impermeability and mechanical properties. It is usually designed based on the closest packing theory, using submicron particles (silica fume) to fill the stacking gaps between micron particles (cement, fly ash, mineral powder), and using micron particles (cement, fly ash, mineral powder) to fill the stacking gaps between millimeter particles (aggregates), to obtain concrete with a compressive strength of more than 120MPa. In order to improve the toughness of ultra-high performance concrete and prevent cracking, fibers are usually added. Due to its excellent working performance, mechanical properties and durability, it is increasingly used in component preparation. At present, it is mostly used in beam-slab-column structures, thin-wall structures, thin-shell structures, repair and reinforcement, etc.

[0003] Concrete tiles, also known as cement-based tiles, are made of cement, sand, fiber, admixtures, etc. through filter pressing, roller pressing, or plate pressing. Traditional concrete tiles are brittle, low in strength, and poor in durability, resulting in small single-piece area and large thickness, which makes them unable to be used on a large scale in industrial plants. They are currently mainly used in ordinary houses, villas, and high-rise buildings. Although ultra-high performance concrete has high toughness and strength, good durability, and resistance to water erosion, it has high flowability, usually with an expansion of more than 550mm, and due to the use of ultra-fine powder, its viscosity is relatively high, usually 5-7 times that of ordinary cement concrete, making it unsuitable for existing tile production lines, and thus rarely used in the preparation of tiles. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a method for producing ultra-high performance concrete tiles to solve the problem that the existing tile line production method is not suitable for the production of ultra-high performance concrete tiles.

[0005] The technical solution adopted by the present invention to solve the technical problem is: construct a production method of ultra-high performance concrete tiles, the production equipment adopted includes a high-frequency vibration platform, a transition platform and a shaping frame arranged side by side, a conveyor belt is arranged above the high-frequency vibration platform, a buffer hopper and a slurry hopper are arranged above the conveyor belt, a material distribution roller is arranged behind the slurry hopper, a cutting device and a leveling roller are arranged on the transition platform, and a shaping template is arranged on the shaping frame; the production method comprises the following steps:

[0006] S1. Lay the bottom anti-aging film on the conveyor belt;

[0007] S2. Load the ultra-high performance concrete tile slurry into the slurry hopper, start the conveyor belt, and open the slurry hopper, so that the ultra-high performance concrete tile slurry flows out from the discharge port of the slurry hopper onto the bottom anti-aging film, and the cloth roller located behind the slurry hopper rolls to flatten the slurry on the bottom anti-aging film to a set size;

[0008] S3, start the high-frequency vibration platform under the conveyor belt to vibrate the ultra-high performance concrete tile slurry to make the ultra-high performance concrete tile slurry vibrate and compact;

[0009] S4. Turn off the high-frequency vibration platform and lay the upper anti-aging film on the ultra-high performance concrete tile slurry;

[0010] S5, start the conveyor belt, convey the ultra-high performance concrete tile slurry with the bottom anti-aging film and the upper anti-aging film to the transition platform through the conveyor belt, and use the cutting device to cut the ultra-high performance concrete tile according to the set cutting size;

[0011] S6. Use a leveling roller to level the cut ultra-high performance concrete tile according to the set pressure, and then transport it to the shaping template of the shaping frame by a conveyor belt. When the ultra-high performance concrete tile is at a certain distance from the shaping frame, it is transported to the shaping template by a first transport device.

[0012] According to the above scheme, in step S6, a through-beam photoelectric sensor is installed at one end of the conveyor belt close to the shaping frame. When the ultra-high performance concrete tile passes through the through-beam photoelectric sensor, the through-beam photoelectric sensor wirelessly transmits the signal to the control unit of the first conveying device. The control unit of the first conveying device issues a conveying instruction to convey the ultra-high performance concrete tile to the shaping template and stack the upper shaping template.

[0013] According to the above scheme, when the first transport device is transporting the ultra-high performance concrete tiles, the number of stacking layers of the ultra-high performance concrete tiles is recorded in real time. When the number of stacking layers of the ultra-high performance concrete tiles reaches the set number of stacking layers, a transport instruction is sent to the second transport device through the wireless transmission device, and the second transport device moves the ultra-high performance concrete tiles to the curing room for curing.

[0014] According to the above scheme, the set number of stacking layers L is determined by the deadweight G1 of each ultra-high performance concrete tile, the deadweight G2 of each shaping mold, the maximum force F of slurry extrusion in the tile per unit area, and the carrying capacity C of the handling equipment. The parameters meet the following requirements:

[0015]

[0016] Among them, m is the loading range limit coefficient of the handling equipment, the maximum force F of slurry extrusion per unit area of ​​the tile is determined by experiment, and g is the acceleration of gravity.

[0017] According to the above scheme, a first material level sensor and a second material level sensor are installed on the inner wall of the slurry hopper. When the first material level sensor detects that the material level is lower than the first set threshold, the buffer hopper that receives the signal injects ultra-high performance concrete tile slurry into the slurry hopper through the down pipe; when the second material level sensor detects that the material level is higher than the second set threshold, the buffer hopper that receives the signal stops injecting ultra-high performance concrete tile slurry into the slurry hopper.

[0018] According to the above scheme, the first set threshold is determined by the distance between the material level and the slurry hopper outlet, and the first set threshold is 1 / 4-1 / 3 of the total height of the slurry hopper; the second set threshold is determined by the distance between the material level and the slurry hopper inlet, and the second set threshold is 1 / 5-1 / 4 of the total height of the slurry hopper.

[0019] According to the above scheme, the step S2 further includes the following steps:

[0020] S21, dividing the steel fiber used to prepare the ultra-high performance concrete tile slurry into two parts;

[0021] S22, mixing one of the two parts of steel fiber into the ultra-high performance concrete tile slurry;

[0022] S23, the prepared ultra-high performance concrete tile slurry is loaded into the slurry hopper, the conveyor belt is started, and the slurry hopper is opened, so that the ultra-high performance concrete tile slurry flows out from the discharge port of the slurry hopper onto the bottom anti-aging film, and the distribution roller located behind the slurry hopper rolls to flatten the slurry on the bottom anti-aging film to a first set size to form a first layer of ultra-high performance concrete tiles, and the conveyor belt and the slurry hopper are closed;

[0023] S24, evenly spreading the other of the two steel fibers on the surface of the first layer of ultra-high performance concrete tiles;

[0024] S25, start the conveyor belt and open the slurry hopper, so that the ultra-high performance concrete tile slurry flows out from the discharge port of the slurry hopper onto the bottom anti-aging film, and the cloth roller located behind the slurry hopper rolls to flatten the slurry on the bottom anti-aging film to a second set size, forming a second layer of ultra-high performance concrete tiles.

[0025] According to the above scheme, in step S3, the vibration frequency of the high-frequency vibration platform is 5000-6000 times / min, and the vibration amplitude is 0.05-0.1 mm.

[0026] The production method of the ultra-high performance concrete tile of the present invention has the following beneficial effects:

[0027] 1. Compared with the existing tile production process, the present invention sets a distribution roller behind the slurry hopper so that the distribution roller and the conveyor belt keep the same linear speed for rolling, and controls the distance between the distribution roller and the bottom anti-aging film so that the ultra-high performance concrete tile slurry can be evenly distributed on the bottom anti-aging film according to the specified size, and then the density of the ultra-high performance concrete tile slurry can be improved by a high-frequency vibration platform. The whole process relies on the fluidity of the slurry itself and completes the slurry distribution with the help of the rolling of the distribution roller, which can effectively realize the preparation of ultra-high performance concrete tiles. The ultra-high performance concrete tiles prepared by the method of the present invention have excellent longitudinal and transverse flexural strength.

[0028] 2. The present invention realizes automatic control of tile transportation, tile handling and slurry bucket feeding through sensors and wireless transmission means during the process of conveying green tiles to shaping templates, transporting green tiles to curing rooms and feeding into slurry buckets. Compared with the existing manual method of tiles, the present invention can greatly reduce the workload of workers. At the same time, the present invention adopts intelligent control to realize green tile transportation and tile handling, which can effectively avoid the problems of slurry leakage and deformation that are easy to occur during manual lifting, and the number of stacking layers can be controlled to effectively avoid the uniformity of thickness and density of different ultra-high performance concrete tiles. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments, in which:

[0030] Figure 1 is a schematic diagram of equipment used in the production method of ultra-high performance concrete tiles of the present invention;

[0031] Figure 2 is a schematic diagram of a method for producing ultra-high performance concrete tiles of the present invention; DETAILED DESCRIPTION

[0032] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0033] Example 1

[0034] like Figure 1 As shown, the production equipment adopted by the production method of the present invention includes a high-frequency vibration platform 3, a transition platform 9, a bottom anti-aging film 2, an upper anti-aging film 6 and a shaping frame 10 arranged side by side, a conveyor belt 1 is arranged above the high-frequency vibration platform 3, a buffer hopper 4 and a slurry hopper 5 are arranged above the conveyor belt 1, a cloth roller 12 is arranged behind the slurry hopper 5, a cutting device 7 and a leveling roller 8 are arranged on the transition platform 9, and a shaping template 11 is arranged on the shaping frame 10.

[0035] like Figure 2 As shown, the production method of the ultra-high performance concrete tile of the present invention comprises the following steps:

[0036] S1. Lay the bottom anti-aging film on the conveyor belt of the conveyor belt;

[0037] S2. Load the ultra-high performance concrete tile slurry into the slurry hopper, start the conveyor belt, and open the slurry hopper, so that the ultra-high performance concrete tile slurry flows out from the discharge port of the slurry hopper onto the bottom anti-aging film, and the distribution roller located behind the slurry hopper rolls to flatten the slurry on the bottom anti-aging film to a set size. In order to maintain uniform thickness, the linear speeds of the distribution roller and the conveyor belt are consistent during operation;

[0038] S3. Start the high-frequency vibration platform under the conveyor belt to vibrate the ultra-high performance concrete tile slurry at a certain vibration frequency and vibration amplitude to make the ultra-high performance concrete tile slurry vibrate and compact. The vibration frequency is 5000-6000 times / min and the vibration amplitude is 0.05-0.1mm. Under this vibration frequency and vibration amplitude, the slurry on the conveyor belt is subjected to high-frequency micro-amplitude vibration, which can effectively achieve uniform distribution of the slurry and avoid damage to the conveyor belt;

[0039] S4. Turn off the high-frequency vibration platform and lay the upper anti-aging film on the ultra-high performance concrete tile slurry;

[0040] S5, start the conveyor belt, convey the ultra-high performance concrete tile slurry with the bottom anti-aging film and the upper anti-aging film to the transition platform through the conveyor belt, and use the cutting device to cut the ultra-high performance concrete tile according to the set cutting size;

[0041] S6. Use a leveling roller to level the cut ultra-high performance concrete tile according to the set falling pressure, and then transport it to the shaping template of the shaping frame by the conveyor belt. When the ultra-high performance concrete tile is at a certain distance from the shaping frame, it is transported to the shaping template by the first transport device. The falling pressure is set to ensure that the upper anti-aging film is in compliance with the surface of the ultra-high performance concrete tile slurry, so as to avoid squeezing the slurry due to excessive falling pressure.

[0042] In this embodiment, a distributing roller is arranged behind the slurry bucket, so that the distributing roller rolls to distribute the slurry, and the distance between the distributing roller and the bottom anti-aging film is controlled by the slurry bucket, so that the ultra-high performance concrete tile slurry can be evenly distributed on the bottom anti-aging film according to the specified size, and then the density of the ultra-high performance concrete tile slurry can be improved by a high-frequency vibration platform. The whole process relies on the fluidity of the slurry itself and the rolling of the distributing roller to complete the slurry distribution, which can effectively realize the preparation of ultra-high performance concrete tiles. The ultra-high performance concrete tiles prepared by the method of the present invention have excellent longitudinal and transverse flexural strength. The bottom anti-aging film 2 and the upper anti-aging film 6 are both existing products.

[0043] Moreover, in this embodiment, in order to effectively avoid the problems of leakage and deformation that are easy to occur during manual lifting, the step S6 adopts a leveling roller to fall into the ultra-high performance concrete green tile that is cut according to the setting pressure leveling, and then is transported to the shaping template of the shaping frame by the conveyor belt. When the ultra-high performance concrete green tile is a certain distance away from the shaping frame, it is transported to the shaping template by the first transport device, which specifically includes the following steps:

[0044] A through-beam photoelectric sensor is installed at one end of the conveyor belt close to the shaping frame. When the ultra-high performance concrete tile passes through the through-beam photoelectric sensor, the through-beam photoelectric sensor wirelessly transmits the signal to the control unit of the first conveying device. The control unit of the first conveying device issues a conveying instruction to convey the ultra-high performance concrete tile to the shaping template and stack the upper shaping template.

[0045] Furthermore, in order to realize the automated control of the entire tile production line, reduce the work intensity of workers, and improve the preparation accuracy of the obtained ultra-high performance concrete tiles, including the uniformity of size, especially thickness and density distribution, so as to ensure that the obtained ultra-high performance concrete tiles have good mechanical properties, the production method of ultra-high performance concrete tiles also includes the following steps:

[0046] S7. When the first transport device is transporting the ultra-high performance concrete tiles, it records the number of stacking layers of the ultra-high performance concrete tiles in real time. When the number of stacking layers of the ultra-high performance concrete tiles reaches the set number of stacking layers, it sends a transport instruction to the second transport device through the wireless transmission device, and the second transport device moves the ultra-high performance concrete tiles to the curing room for curing.

[0047] The number of stacking layers L is mainly determined by the weight of the slurry used for each ultra-high performance concrete tile G1 (kg), the weight of each shaping mold G2 (kg), the maximum force of slurry extrusion per unit area of ​​the tile F (N), and the carrying capacity of the handling equipment C (t). The following requirements are met between the parameters:

[0048]

[0049] Among them, m is the loading range limit coefficient of the handling equipment, which is usually taken as 0.8. The maximum force F of slurry extrusion per unit area of ​​the tile is determined by experiment, and g is the acceleration of gravity.

[0050] The derivation process of the above formula is:

[0051] g×[L×G1+(1+L)×G2]=F; L×G1+(1+L)×G2=mC. Convert the above two equations into the values ​​of L and take the minimum value.

[0052] For example, assuming that for a 1m×1m×0.005m tile, its bulk density is 2500kg / m 3, then its deadweight G1 is 12.5kg, for a 1m long shaping mold matching the above tile size, its deadweight G2 is 6kg, the carrying capacity of the handling equipment is 5t, and the maximum force F of the slurry extrusion per unit area of ​​the tile is 50000N, then according to the above formula, L is calculated to be 216 layers;

[0053] Assume that for a 3m×1m×0.005m tile, its bulk density is 2500kg / m 3 , then its dead weight G1 is 37.5kg, for the 3m long shaping mold matching the above tile size, its weight G2 is 18kg, the carrying capacity of the handling equipment is 5t, and the maximum force F of slurry extrusion per unit area of ​​the tile is 50000N, then according to the above formula, L is 72 layers.

[0054] At the same time, in actual production, when the slurry hopper is relatively large, its own weight is relatively large, and the weight of the internal slurry makes it consume a lot of energy in the process of moving the material. For this reason, the present embodiment is provided with a buffer hopper, which is connected to the slurry hopper through a down pipe, and a part of the slurry can be temporarily stored in the buffer hopper. When the slurry in the slurry hopper is insufficient, the slurry in the buffer hopper can be injected into the slurry hopper through the down pipe. In addition, in order to realize the automatic control of the entire tile production line and reduce the work intensity of the workers, the present embodiment is provided with a material level sensor near the discharge port and the feed port of the slurry hopper to detect the material level in the slurry hopper. For this reason, the production method of ultra-high performance concrete tiles also includes the following steps:

[0055] S8. Install a first material level sensor and a second material level sensor on the inner wall of the slurry hopper. When the first material level sensor detects that the material level is lower than a first set threshold, the buffer hopper that receives the signal injects ultra-high performance concrete tile slurry into the slurry hopper through a discharge pipe. When the second material level sensor detects that the material level is higher than a second set threshold, the buffer hopper that receives the signal stops injecting ultra-high performance concrete tile slurry into the slurry hopper.

[0056] Among them, the buffer hopper can receive the material level signal in real time, and its instruction to inject ultra-high performance concrete tile slurry into the slurry hopper is not limited to after the tile blanks are transported to the curing room, but can also be used in step S3 ultra-high performance concrete tile slurry pouring process, etc., or in other appropriate steps.

[0057] Among them, the first material level sensor is arranged at a position close to the discharge port of the slurry hopper, and the second material level sensor is arranged at a position close to the feed port of the slurry hopper. At this time, the first set threshold is determined by the distance between the material level and the discharge port of the slurry hopper, and the first set threshold is 1 / 4-1 / 3 of the total height of the slurry hopper; the second set threshold is determined by the distance between the material level and the feed port of the slurry hopper, and the second set threshold is 1 / 5-1 / 4 of the total height of the slurry hopper.

[0058] Example 2

[0059] The ultra-high performance concrete tile is produced by the production method of Example 1, wherein the target size of the ultra-high performance concrete tile blank is 3m×1m×0.005m, and the standard bulk density of the ultra-high performance concrete tile slurry is specified to be 2500kg / m 3 The standard fluidity is 210mm and its label is C120.

[0060] The ultra-high performance concrete tile slurry is loaded into the slurry hopper, the conveyor belt is started, and the slurry hopper is opened, so that the ultra-high performance concrete tile slurry flows out from the discharge port of the slurry hopper to the bottom anti-aging film, and the distribution roller located behind the slurry hopper rolls to flatten the slurry on the bottom anti-aging film to a set size, wherein the rolling speed of the distribution roller and the transmission speed of the conveyor belt are matched to ensure that the slurry can be evenly distributed on the bottom anti-aging film according to the set size; after the pouring is completed, the high-frequency vibration platform is started to increase the uniform density of the slurry, and the vibration frequency is 6000 times / min, and the vibration amplitude is 0.05mm; the other steps are the same as Example 1.

[0061] For the stacking height, it is calculated that the dead weight G1 of the target ultra-high performance concrete tile blank is 37.5 kg; a shaping mold matching the above-mentioned tile blank size is used, and its weight G2 is 18 kg; the carrying capacity of the used handling equipment is 5 t; it is known from experiments that the maximum force F of slurry extrusion per unit area of ​​the tile blank is 48000 N; according to the calculation formula of the stacking number L in Example 1, L is 72 layers, that is, the stacking height of the ultra-high performance concrete tile blank does not exceed 72 layers.

[0062] The produced ultra-high performance concrete tiles were sampled and tested, and the test results are shown in Table 1.

[0063] It can be seen from Table 1 that the ultra-high performance concrete tile obtained by this embodiment has good longitudinal and transverse bending resistance, the ultra-high performance concrete tile obtained has uniform thickness, and the mechanical properties are not much different.

[0066] Example 3

[0067] The difference between this embodiment and embodiment 2 is that:

[0068] After the ultra-high performance concrete tile slurry is loaded into the slurry hopper, the pouring process includes the following steps:

[0069] S21, dividing the steel fiber used to prepare the ultra-high performance concrete tile slurry into two parts;

[0070] S22, mixing one of the two parts of steel fiber into the ultra-high performance concrete tile slurry;

[0071] S23, start the conveyor belt and open the slurry hopper, so that the ultra-high performance concrete tile slurry flows out from the discharge port of the slurry hopper onto the bottom anti-aging film, and the distribution roller located behind the slurry hopper rolls to flatten the slurry on the bottom anti-aging film to a first set size to form a first layer of ultra-high performance concrete tiles, and close the conveyor belt and the slurry hopper;

[0072] S24, evenly spreading the other of the two steel fibers on the surface of the first layer of ultra-high performance concrete tiles;

[0073] S25, start the conveyor belt and open the slurry hopper, so that the ultra-high performance concrete tile slurry flows out from the discharge port of the slurry hopper onto the bottom anti-aging film, and the cloth roller located behind the slurry hopper rolls to flatten the slurry on the bottom anti-aging film to a second set size, forming a second layer of ultra-high performance concrete tiles.

[0074] Among them, the thickness of the first layer of ultra-high performance concrete tiles and the subsequent second layer of ultra-high performance concrete tiles are the same, both of which are 2.5 mm.

[0075] In this embodiment, the ultra-high performance concrete tile slurry is poured in two layers, and steel fibers are spread between the two poured layers of ultra-high performance concrete tiles, which can more effectively avoid the forward distribution of steel fibers and ensure that the obtained ultra-high performance concrete tiles have higher longitudinal flexural strength.

[0076] The produced ultra-high performance concrete tiles were sampled and tested, and the test results are shown in Table 2.

[0077] It can be seen from Table 2 that the ultra-high performance concrete tile obtained by this embodiment has good longitudinal and transverse bending resistance, the ultra-high performance concrete tile obtained has uniform thickness, and the mechanical properties are not much different.
