Description
Technical Field

[0002] Fair-faced concrete refers to an in-situ concrete project that uses the original concrete casting surface or the concrete surface treated with a transparent protective agent as the outer surface, and realizes the aesthetic effect through the natural color and texture of the concrete and the carefully designed and constructed appearance quality. One-time casting without any external decoration are the two most critical points of fair-faced concrete. Fair-faced concrete can present various tones such as light gray, dark gray, white and delicate textures by adjusting the material ratio. In actual production, since the concrete contains solid aggregates such as sand and gravel, when large solid aggregates are located on the concrete surface, there are easily depressions or protrusions, which affect the appearance quality of the concrete project. However, if the large aggregates and small aggregates are mixed separately, it is easy to produce color differences and affect the construction effect. Summary of the Invention

[0025] like Figures 1-4 , as shown in 8:
[0026] A fair - faced concrete processing device includes a bottom plate 000. An inner partition plate 010 is welded to the upper side of the bottom plate 000. A screening mechanism 100 is sleeved outside the inner partition plate 010. The screening mechanism 100 is connected to the bottom plate 000 by bolts. An elastic base 020 is slidably connected to the inner side of the inner partition plate 010 through a spring. An upper connecting ring 030 is connected to the upper side of the inner partition plate 010 by bolts, and a downward - pressing mechanism 200 is installed on the upper connecting ring 030. The screening mechanism 100 includes a lower sieve plate 110, an intermediate sieve plate 120, an upper sieve plate 130, and three vertical connecting plates 140. The three vertical connecting plates 140 are evenly distributed and connected to the outside of the bottom plate 000 by bolts. The lower sieve plate 110, the intermediate sieve plate 120, and the upper sieve plate 130 are detachably connected to the inner sides of the three vertical connecting plates 140 in sequence from bottom to top. The downward - pressing mechanism 200 includes three connecting columns 210. The three connecting columns 210 are evenly distributed on the upper side of the upper connecting ring 030. An upper cover 220 is connected to the upper sides of the three connecting columns 210 by bolts. A lower pressing plate 230 is slidably connected to the lower side of the upper cover 220 through an electric push rod.
[0027] When using a fair - faced concrete processing device to process fair - faced concrete, it is necessary to pre - mix cement, aggregates, water, and other auxiliary materials into pre - mixed concrete in advance. It is possible to pre - manufacture pre - mixed concrete or mix raw materials on - site according to requirements.
[0028] Then, it is possible to adjust the screening mechanism 100 according to the required aggregate diameter. Move the intermediate sieve plate 120 and the upper sieve plate 130 upward by a certain distance in sequence and fix them on the vertical connecting plate 140, so that multiple gaps with unequal distances are formed between the lower sieve plate 110, the intermediate sieve plate 120 and the upper sieve plate 130. The gap distance gradually increases from top to bottom. Then, the premixed concrete can be placed inside the inner partition plate 010. Under normal conditions, the elastic base 020 can be kept above the uppermost gap under the action of the spring. After the premixed concrete is placed inside the inner partition plate 010, the self-weight of the premixed concrete can slowly press down the elastic base 020, exposing the uppermost gap. Then, the pressing mechanism 200 can be started, so that the electric push rod can push the lower pressing plate 230 to gradually press down, and continuously push and squeeze the premixed concrete downward, so that the premixed concrete can be gradually screened out from the uppermost gap. At this time, the aggregates with larger diameters cannot pass through the uppermost gap, and thus can continue to be pushed downward by the lower pressing plate 230, causing the spring to gradually contract and compress until the second-uppermost gap is gradually exposed. At this time, the aggregates with diameters larger than the uppermost gap and smaller than the second-uppermost gap can be screened out from the second-uppermost gap. Then, the lower pressing plate 230 can continue to push the premixed concrete downward under the push of the electric push rod until all the premixed concrete passes through the gaps and is screened out respectively, so that the screening work of the premixed concrete can be completed, and fair-faced concrete containing aggregates with different diameters can be obtained. By screening in the above way, it can be ensured that the premixed concrete after screening only has differences in aggregate diameter, while the proportions of other components are the same. At present, in the prior art, materials of the same brand, same specification, same color and same batch are used. At the same time, the materials are strictly fed and stirred according to the mix ratio to avoid color difference as much as possible. However, in actual production, since the concrete contains coarse aggregates and fine aggregates, when large coarse aggregates are located on the surface of the concrete, there are easily depressions or protrusions, which affect the appearance quality of the concrete project. But if the large coarse aggregates and fine aggregates are mixed separately, color difference is likely to occur, affecting the construction effect. Therefore, the present invention creatively proposes to first mix the coarse aggregates and fine aggregates to prepare premixed concrete, and then screen it to obtain fair-faced concrete containing aggregates with different diameters, which can ensure that the premixed concrete after screening only has differences in aggregate diameter, while the proportions of other components are the same, so as to avoid color difference as much as possible. And the present invention also makes clever use of the viscosity of the premixed concrete, so that the aggregates will be mixed with cement, water and other auxiliary materials as a whole and screened out from the outlet of the screening mechanism 100 during the screening process. In addition, when using a filtering device with mesh holes such as a filter screen for screening concrete aggregates, due to the large mass of the concrete, when a large number of aggregates with larger diameters block the mesh holes, the mesh holes of the filter screen are easily broken by the concrete, resulting in deformation or damage, and it is difficult to clean the concrete attached and solidified on the filter screen, so it cannot be used continuously.
[0029] Example 1 of the application of making fair-faced concrete: Different containers are connected to the outlet position of the screening mechanism 100. Concrete containing larger-diameter aggregates is used to pour the inner formwork, and then the pouring is carried out layer by layer outward. A fair-faced concrete building with only smaller-diameter aggregates on the surface can be obtained, reducing the influence of large solid aggregates on the surface of the fair-faced concrete. And since the concrete used is prepared by screening premixed concrete, the surface of the made fair-faced concrete project can be ensured to have no color difference.
[0030] Example 2 of the application of making fair-faced concrete: The screened concrete directly flows out in a mixed state from the outlet position of the screening mechanism 100. At this time, the aggregate diameter of the screened concrete increases from outside to inside. Therefore, the overall pouring of the fair-faced concrete building can be directly carried out by connecting the outlet position of the screening mechanism 100 to the area to be poured. Thus, the possibility of internal stratification in the made fair-faced concrete project can be reduced. At the same time, it can be ensured that the surface of the fair-faced concrete building only contains smaller-diameter aggregates and has no color difference. The inner partition 010 can be connected to a rotatable disc, so that the outlet position of the screening mechanism 100 can rotate around the disc. Furthermore, during the pouring process, especially during the pouring of a cylindrical structure, the concrete containing smaller-diameter aggregates can always be located on the surface side, and thus the construction of the fair-faced concrete project can be quickly completed.
[0031] Secondly, due to the fact that the premixed concrete is affected by the downward pressure from the lower pressing plate 230 of the electric push rod and the upward thrust from the elastic base 020 from both the upper and lower sides, it is sieved out from the gap. Thus, it can be ensured that when the pressure and the thrust are balanced, the premixed concrete can be stably sieved out from the gap. That is, the setting of the spring can adjust the thrust received by the premixed concrete. When the diameter of the premixed concrete aggregate is small, it can be quickly sieved out from the gap. When the diameter of the premixed concrete aggregate is large, the elastic base 020 can move downward, causing the lower pressing plate 230 and the whole premixed concrete to move downward until the premixed concrete can be sieved out from other gaps. Thereby, it can be ensured that the setting of multiple gaps will not affect the screening efficiency of the premixed concrete. At the same time, after the aggregate with a larger diameter is quickly sieved out from the lower gap, the spring can push the elastic base 020 upward, closing the lower gap by the elastic base 020, so that the premixed concrete can only be sieved out through the upper gap. That is, when the lower pressing plate 230 pushes the premixed concrete for screening, the premixed concrete will first contact the uppermost gap, enabling the concrete containing aggregates with a smaller diameter to be sieved out from the uppermost gap. Then, the aggregates with a larger diameter can block the uppermost gap, preventing the concrete from continuing to be sieved out from the uppermost gap. At this time, the premixed concrete is stuffed inside the screening mechanism 100, causing the lower pressing plate 230 to push the premixed concrete and the elastic base 020 to move downward simultaneously until the concrete with aggregates having a larger diameter at the bottom of the premixed concrete is sieved out from the second-uppermost gap. At this time, the aggregates with an even larger diameter can continue to accumulate at the bottom of the premixed concrete until they are sieved out after contacting a gap with sufficient clearance; thereby, the gap through which the premixed concrete is sieved out can be dynamically changed by the up-and-down sliding of the elastic base 020, ensuring that the processing device can continuously screen the premixed concrete and preventing the situation where all the premixed concrete is concentrated in the lowermost gap for screening, which may lead to poor screening effect.
[0032] Secondly, when the premixed concrete is pressed downward by the lower pressing plate 230, if the upper gap has been blocked by aggregates with a larger diameter, then at this time, the aggregates with a smaller diameter can only be sieved out together with the aggregates with a larger diameter from the exposed lower gap. That is, the blocked gap on the upper side can make the premixed concrete only be sieved out from the lower gap, thus avoiding the situation where only aggregates with a larger diameter are sieved out from the lower gap while there is less fine material such as cement, resulting in different strengths of the screened concrete. When the lower pressing plate 230 moves downward to the position of the upper gap, the lower pressing plate 230 can push the aggregates at the edge of the blocked gap to slide downward and can simultaneously block the upper gap instead of the aggregates with a larger diameter. Thereby, while ensuring the screening efficiency of the lower gap for the premixed concrete, it can be avoided that the aggregates with a larger diameter are always stuck at the edge of the gap, causing the upper gap to be continuously blocked and unusable.
[0033] Detachable rubber strips can be added to the upper side of the lower sieve plate 110, the lower side of the upper sieve plate 130, and the upper and lower sides of the intermediate sieve plate 120, that is, detachable rubber strips are added to both sides of the gap. When aggregates with a larger diameter enter the gap, the rubber strips on both sides of the gap can undergo certain deformation, causing the aggregates with a larger diameter to be stuck inside the gap. When the lower pressing plate 230 moves downward, the lower pressing plate 230 can exert a push on the aggregates with a larger diameter, causing the rubber strips on both sides to continue to deform, so that the aggregates with a larger diameter can be disengaged from the gap without damaging the lower sieve plate 110, the intermediate sieve plate 120, or the upper sieve plate 130. In addition, the detachable rubber strips can be directly removed and replaced after elastic failure or damage, thus facilitating the maintenance of the processing device.
[0034] In addition, the diameter of the screened aggregates can be controlled by adjusting the heights of the intermediate sieve plate 120 and the upper sieve plate 130. Since the intermediate sieve plate 120 and the upper sieve plate 130 are rings fixed to the outside of the vertical connecting plate 140, when the premixed concrete is screened out through the gap, the premixed concrete can exert an outward pressure on the intermediate sieve plate 120 and the upper sieve plate 130. At this time, the circular ring shape can disperse the pressure received by the intermediate sieve plate 120 and the upper sieve plate 130 to be jointly borne by multiple vertical connecting plates 140, that is, the intermediate sieve plate 120 and the upper sieve plate 130 can receive a uniform outward pressure during the screening process, and thus will not shift or deform, avoiding a decrease in the aggregate screening efficiency; and by dynamically adjusting the gap size by adjusting the heights of the intermediate sieve plate 120 and the upper sieve plate 130, after the concrete adheres and solidifies inside the gap, the intermediate sieve plate 120 and the upper sieve plate 130 can be separated or directly removed for cleaning to restore the normal screening ability of the processing device.
[0035] As Figures 5-6 shown:
[0036] The intermediate sieve plate 120 and the lower side of the upper sieve plate 130 are both welded with cleaning elastic plates 150. Two symmetrically arranged outer partition plates 040 are connected to the outside of the screening mechanism 100 by screws; the arrangement of the two outer partition plates 040 can completely seal the outside of the screening mechanism 100 to prevent the premixed concrete from being screened out from other positions; at the same time, since there are gap grooves that are prone to concrete accumulation and difficult to clean between the lower sieve plate 110, the intermediate sieve plate 120, the upper sieve plate 130 and the inner partition plate 010 and the outer partition plate 040 when the intermediate sieve plate 120 and the upper sieve plate 130 are adjusted upward. After the screening is completed, the fixation between the intermediate sieve plate 120 or the upper sieve plate 130 and the vertical connecting plate 140 can be released, and the intermediate sieve plate 120 or the upper sieve plate 130 can be pushed downward, so that the cleaning elastic plate 150 gradually contacts the lower sieve plate 110 or the intermediate sieve plate 120 located below. At this time, the middle part of the lower side of the cleaning elastic plate 150 can contact the lower sieve plate 110 or the intermediate sieve plate 120 located below in advance, and gradually deforms as the intermediate sieve plate 120 or the upper sieve plate 130 is pushed downward, so that the cleaning elastic plate 150 can gradually push and deform from the middle part that first contacts the lower sieve plate 110 or the intermediate sieve plate 120 located below to both sides, and then the premixed concrete between the cleaning elastic plate 150 and the lower sieve plate 110 or the intermediate sieve plate 120 located below can be laterally extruded outward, that is, the premixed concrete in the gap groove can be obliquely pushed out from the opening through the cleaning elastic plate 150, thereby avoiding the situation where the aggregate stays in the gap groove, resulting in the inability of the intermediate sieve plate 120 or the upper sieve plate 130 to move downward and close with the lower sieve plate 110 or the intermediate sieve plate 120 located below.
[0037] As Figures 5-6 shown:
[0038] An intermediate guide plate 121 is welded to the outside of the intermediate sieve plate 120, and an upper guide plate 131 is welded to the outside of the upper sieve plate 130. The upper guide plate 131 is sleeved outside the intermediate guide plate 121 and is in close contact with the two wings of the intermediate guide plate 121; thus, when the premixed concrete is screened out from the gap, the two sides can be blocked by the upper guide plate 131 or the intermediate guide plate 121, and then it is ensured that the premixed concrete can be accurately screened out from the outlet of the screening mechanism 100. At the same time, a communication cavity can be formed between the mutually sleeved and closely attached upper guide plate 131 and the intermediate guide plate 121, and then it is ensured that the premixed concrete after screening can accurately fall into the predetermined position along the communication cavity and will not be mixed with each other.
[0039] The setting of the mutual sleeving of the intermediate guide plate 121 and the upper guide plate 131 can ensure that relative sliding can occur between the intermediate guide plate 121 and the upper guide plate 131 and always maintain sealing during the process of adjusting the height of the intermediate sieve plate 120 or the upper sieve plate 130.
[0040] As Figure 6 shown:
[0041] The upper side surface of the intermediate guide plate 121 is an inclined surface, which can facilitate the sliding down of the premixed concrete after screening, and prevent the premixed concrete after screening from staying on the upper side surface of the intermediate guide plate 121 and being difficult to clean up.
[0042] As Figure 4 shown:
[0043] A plurality of the intermediate sieve plates 120 are provided, and the plurality of intermediate sieve plates 120 are all arranged between the lower sieve plate 110 and the upper sieve plate 130. The intermediate guide plates 121 on the plurality of intermediate sieve plates 120 are nested with each other, and the two wings of adjacent intermediate guide plates 121 are closely attached; thus, the number of screening layers of the premixed concrete can be increased by arranging the plurality of intermediate sieve plates 120, and the larger-diameter aggregates in the premixed concrete after screening can be more evenly distributed.
[0044] As Figure 9 shown:
[0045] The three vertical connecting plates 140 and the three connecting columns 210 are arranged in a staggered manner with the bottom plate 000 as the center; thus, it can be ensured that the opening between the two connecting columns 210 can be arranged on the opposite side of the intermediate guide plate 121 and the upper guide plate 131 at the position between the two vertical connecting plates 140, so as to avoid the premixed concrete falling on the upper side of the upper guide plate 131 and mixing with the premixed concrete after screening when the premixed concrete is placed into the screening mechanism 100, and further ensure that there are no larger-diameter aggregates remaining in the outer area of the premixed concrete after screening.
[0046] As Figure 7 shown:
[0047] The upper side surface of the elastic base 020 is inclined. The inclined upper side surface of the elastic base 020 can play a guiding role, enabling the premixed concrete to gradually slide down under its own gravity and slide towards the position of the gap opening.
[0048] At the same time, the inclined upper side surface of the elastic base 020 can ensure that when the lower pressing plate 230 presses the premixed concrete downward, the un-screened concrete can slide down obliquely and stay between the elastic base 020 and the lower pressing plate 230, so as to improve the influence of the larger-diameter aggregates on the gap by stacking the aggregates, accelerate the blocking speed of the larger-diameter aggregates on the gap, and avoid the situation that most of the cement and the smaller-diameter aggregates are screened out from the upper gap, resulting in only the larger-diameter aggregates and a small amount of cement and other fine materials being screened out from the lower gap.
[0049] As Figure 4 shown:
[0050] The vertical connecting plate 140 is provided with a plurality of countersunk threaded holes, and the intermediate sieve plate 120 or the upper sieve plate 130 can be fixed to the vertical connecting plate 140 by screwing screws from the countersunk threaded holes to the outside of the intermediate sieve plate 120 or the upper sieve plate 130. In addition, the provision of the countersunk threaded holes can avoid interference between the bolts and the outer partition plate 040.
[0051] A concrete production process comprises the following steps:
[0052] S1: Cement, aggregate, water and other auxiliary materials are fully mixed to prepare premixed concrete;
[0053] S2: adjusting the positions of the intermediate sieve plate 120 and the upper sieve plate 130 according to the aggregate diameter and screening requirements, and fixing the intermediate sieve plate 120 and the upper sieve plate 130 on the vertical connecting plate 140;
