Description

Technical Field

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

[0002] In the future, with the continuous advancement of urbanization in my country, urban land resources will become increasingly scarce. This scarcity will inevitably drive the development of high-rise and densely packed buildings, making mutual shading between building clusters unavoidable. This is especially true for building clusters near super high-rise buildings and basements, where ensuring adequate natural lighting is crucial. Currently, these buildings often rely on artificial lighting to meet visual needs. Over time, this will lead to a continuous increase in the proportion of lighting energy consumption in total energy consumption, directly increasing building energy consumption. This increased energy consumption will inevitably contribute to problems such as the greenhouse effect, smog, and resource depletion.

[0003] Translucent concrete, a new type of functional building material, is made by combining translucent materials such as plastic optical fibers, translucent resins, and glass rods with ordinary concrete according to certain preparation methods and processes. By using translucent materials as light guides, it transmits green, environmentally friendly, and healthy natural light from the outside into the interior, thereby improving the building's lighting level and quality while reducing building lighting energy consumption. It overturns the dull, dense, and dark feeling that traditional walls bring to people.

[0004] Light-guiding fibers are commonly used materials in the preparation of translucent concrete. During the preparation of translucent concrete, light-guiding fibers tend to float in the concrete, which increases the difficulty of preparing translucent concrete and can also affect the overall light transmission effect of the translucent concrete after molding. Summary of the Invention

[0005] The main objective of this invention is to provide a method for preparing translucent concrete, which aims to solve the technical problem in the prior art where light-guiding fibers easily float in the concrete during the preparation process, thus affecting the overall light transmission effect of the translucent concrete after molding.

[0006] This invention provides a method for preparing translucent concrete, characterized by comprising the following steps:

[0007] We provide rolled optical fibers and translucent concrete molds;

[0008] The rolled optical fiber is cut into a fixed length, and the cut optical fiber is placed into the optical fiber groove in the translucent concrete mold.

[0009] A fixative is introduced into a translucent concrete mold to fix and shape the light-guiding fiber, thereby forming a light-guiding fiber preform.

[0010] The optical fiber prefabricated component is placed in a concrete template, a first cement mortar is injected into the concrete template, and the first cement mortar is vented.

[0011] After the first cement mortar has cured, the first cement mortar is demolded and cured to form translucent concrete.

[0012] The translucent concrete undergoes surface optimization treatment;

[0013] The translucent concrete mold includes a mold body, on which a plurality of light-guiding fiber grooves are formed extending longitudinally and spaced apart laterally. A plurality of grouting grooves extending laterally and spaced apart longitudinally are provided between adjacent light-guiding fiber grooves, and the two ends of each grouting groove are respectively connected to the two corresponding light-guiding fiber grooves.

[0014] Preferably, each of the two ends of the plurality of optical fiber channels is provided with a movable door that is slidably connected thereto.

[0015] Preferably, the mold body is made of plastic or steel.

[0016] Preferably, the height of the plurality of optical fiber channels from their bottom surface to their opening end face is the same as the height of the plurality of grouting channels from their bottom surface to their opening end face; and / or,

[0017] The number of optical fiber slots is set to 4-8, the optical fiber slots are 40mm-200mm long, 5mm-20mm wide, and 5mm-20mm high, and the spacing between two adjacent optical fiber slots is 3mm-5mm; and / or,

[0018] The width of the grouting groove is 5mm-20mm, and the spacing between two adjacent optical fiber grooves is 5mm-10mm.

[0019] Preferably, the fixing agent is a second cement mortar;

[0020] The process of introducing a fixative into a translucent concrete mold to fix and shape the light-guiding fibers to form a prefabricated light-guiding fiber component includes:

[0021] A second cement mortar is injected into the plurality of grouting grooves in the mold, and the second cement mortar is vented.

[0022] After the second cement mortar has cured, it is demolded to form a light-guiding fiber preform.

[0023] Preferably, the density of the second cement mortar is higher than that of the first cement mortar, so that the optical fiber preform remains stable in the first cement mortar.

[0024] Preferably, the surface optimization treatment of the translucent concrete includes:

[0025] The translucent concrete surface is ground to expose the light-guiding fiber, and then polished.

[0026] Preferably, before the step of cutting the rolled optical fiber into a fixed length and placing the cut optical fiber into a translucent concrete mold, the method further includes:

[0027] A thin film is attached to the inner wall of the mold for the translucent concrete precast component.

[0028] Preferably, before the step of demolding the second cement mortar after it has cured to form a fiber optic preform, the method further includes:

[0029] During the curing process of the second cement mortar, it is covered and cured.

[0030] This invention increases the weight of the light-guiding fibers by initially encapsulating them in cement slurry, preventing them from floating during the preparation of translucent concrete and reducing difficulties in the concrete preparation process. Furthermore, the prefabrication of the light-guiding fiber components ensures sufficient vibration during the translucent concrete preparation, increasing its density, reducing internal defects, and extending its service life. Specifically, using high-density mortar to prepare the light-guiding fiber prefabrication components and low-density mortar to prepare the translucent concrete reduces the density difference between the light-guiding fibers and the cement mortar, increasing the uniformity within the translucent concrete, reducing internal defects, and further enhancing the light transmission effect of the concrete. Simultaneously, during the later stages of concrete manufacturing, the light-guiding fiber prefabrication components can be arranged into specific shapes according to actual conditions, thus forming luminescent concrete with specific patterns after the concrete has set. This manufacturing method also makes the production of luminescent concrete with specific luminescent patterns more convenient. Attached Figure Description

[0038] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0039] 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 a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0040] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0041] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0042] Translucent concrete, a new type of functional building material, is made by combining translucent materials such as plastic optical fibers, translucent resins, and glass rods with ordinary concrete according to certain preparation methods and processes. By using translucent materials as light guides, it transmits green, environmentally friendly, and healthy natural light from the outside into the interior, thereby improving the building's lighting level and quality while reducing building lighting energy consumption. It overturns the dull, dense, and dark feeling that traditional walls bring to people.

[0043] Light-guiding fibers are commonly used materials in the preparation of translucent concrete. During the preparation of translucent concrete, light-guiding fibers tend to float in the concrete, which increases the difficulty of preparing translucent concrete and can also affect the overall light transmission effect of the translucent concrete after molding.

[0044] To address the above problems, this invention proposes a translucent concrete mold 100. Figures 1 to 2 This is a schematic diagram of an embodiment of the translucent concrete mold 100 of the present invention.

[0045] Please refer to Figure 5 This invention proposes a translucent concrete mold 100, in which multiple evenly spaced light-guiding fiber grooves 11 and grouting grooves 12 are respectively arranged along the transverse and longitudinal directions of the mold body 1 of the translucent concrete mold 100. Figure 5 As shown, the plurality of grouting tanks 12 are connected to the plurality of optical fiber tanks 11 to form a passage between the plurality of optical fiber tanks 11. This allows the grout to flow smoothly through the grouting tanks 12 into the plurality of optical fiber tanks 11 during grouting, and also ensures good flowability of the grout in each optical fiber tank 11 during the grout treatment process, thereby making the characteristics of the grout in the plurality of optical fiber tanks 11 consistent.

[0046] In order to enable the aforementioned translucent concrete mold 100 to adaptably manufacture translucent concrete of various thicknesses in practical applications and reduce the manufacturing cost of opening different molds, in this embodiment, movable doors 2 are provided on the inner walls of both ends of the multiple light guide fiber grooves 11 and are slidably connected thereto. In actual use, light guide fibers of a specific length can be placed into the multiple light guide fiber grooves 11 according to actual requirements, and then the movable doors 2 are slid to limit the two ends of the light guide fibers. Then, grout is injected through the grouting groove 12 to obtain light guide fiber preforms of different heights, thereby enabling the manufacture of luminous concrete of different thicknesses through the light guide fiber preforms of different thicknesses.

[0047] In this process, by manufacturing the prefabricated light-guiding fiber components, the lightweight light-guiding fibers can be prefabricated as a single unit during the manufacturing of translucent concrete. This increases the overall weight of the light-guiding fibers and reduces the density difference between the fibers and the concrete. The prefabricated light-guiding fibers can then be solidified into the concrete during the later stages of concrete manufacturing to create translucent concrete. This effectively avoids the problem of traditional light-guiding fibers being too light and prone to floating in concrete, making them difficult to fix. This reduces the difficulty of manufacturing translucent concrete. Furthermore, during the later stages of concrete manufacturing, the prefabricated light-guiding fibers can be arranged into specific shapes according to actual conditions, resulting in luminescent concrete with specific patterns after the concrete has solidified. This manufacturing method also makes the production of luminescent concrete with specific luminescent patterns more convenient.

[0048] The mold body 1 can be made of steel, or it can be made of plastic to reduce mold opening costs.

[0049] In addition, in order to make the optical fiber preform easy to handle and aesthetically pleasing after it is formed, the multiple optical fiber grooves 11 and the multiple grouting grooves 12 have the same groove depth.

[0050] The number of optical fiber grooves 11 is set to 4-8, with specific parameters of groove length 40mm-200mm, width 5mm-20mm, and height 5mm-20mm, and the distance between two adjacent optical fiber grooves 11 is 3mm-5mm; the width of the grouting groove 12 is 5mm-20mm, and the distance between two adjacent optical fiber grooves 11 is 5mm-10mm. The number of optical fiber grooves 11 is set to multiple. After the optical fiber preform is formed, each optical fiber groove 11 can form one optical fiber preform. After forming, multiple optical fiber preforms are connected into a whole. According to the actual use requirements, multiple optical fiber preforms can be separated into multiple individual parts, or their overall structure can be retained to reduce the installation steps of placing multiple optical fiber preforms when the luminous concrete is finally formed. Whether to wind-power multiple optical fiber preforms after forming or to retain them as a whole can be selected and determined according to the specific requirements of the actual luminous pattern.

[0051] Please refer to the following: Figures 1-4 This invention also proposes a method for preparing translucent concrete; please refer to [the relevant documentation]. Figures 1-2 , Figures 1-2 This is a schematic flowchart of the first embodiment of the method for preparing translucent concrete provided by the present invention. The method for preparing translucent concrete includes the following steps:

[0052] S100 provides a roll of optical fiber and a translucent concrete mold 100, wherein the translucent concrete mold 100 includes a mold body 1, on which a plurality of optical fiber grooves 11 extending longitudinally and spaced apart in the transverse direction are formed, and a plurality of grouting grooves 12 extending laterally and spaced apart in the longitudinal direction are provided between adjacent optical fiber grooves 11, and the two ends of each grouting groove 12 are respectively connected to the two corresponding optical fiber grooves 11.

[0053] S200 cuts the rolled optical fiber into a fixed length and places the cut optical fiber into the optical fiber groove 11 in the translucent concrete mold 100;

[0054] S300 introduces a fixative into the grouting groove 12 to fix and shape the optical fiber to form an optical fiber preform;

[0055] S400 places the optical fiber prefabricated component in a concrete template, injects the first cement mortar into the concrete template, and vents the first cement mortar.

[0056] S500 After the first cement mortar has cured, the first cement mortar is demolded and cured to form translucent concrete.

[0057] S600 performs surface optimization treatment on the translucent concrete.

[0058] In the above embodiments, multiple light-guiding fiber prefabricated components of corresponding lengths can be manufactured using the light-guiding cement mold according to the actual required thickness of the translucent concrete. Finally, the light-guiding fiber prefabricated components are molded by pouring concrete to form translucent concrete. During this process, the light-guiding fiber prefabricated components have integrally fixed the light-guiding fibers, effectively increasing the overall weight of the light-guiding fibers. This ensures that the molded light-guiding fibers remain stable in the first cement mortar during subsequent pouring of the first cement mortar, preventing them from floating due to their low density. Furthermore, because the light-guiding fiber prefabricated components remain stable in the first cement mortar, the subsequent injection of luminescent concrete into the first cement mortar allows for sufficient vibration and air removal of the first cement mortar, increasing the density of the translucent concrete, reducing internal defects, and extending its service life.

[0059] In order to ensure that the translucent concrete has good light transmittance after molding, step S600 performs surface optimization treatment on the translucent concrete, including:

[0060] The translucent concrete surface is ground to expose the light-guiding fiber, and then polished.

[0061] In the above steps, after the light-guiding fiber is exposed, the concrete can exhibit good light transmittance.

[0062] Additionally, before step S200, which involves cutting the rolled optical fiber into a fixed length and placing the cut optical fiber into a translucent concrete precast mold, the process further includes:

[0063] S110 is attached to the inner wall of the translucent concrete mold 100 with a thin film.

[0064] In the above embodiments, the thin film is used to increase the airtightness of the translucent concrete mold 100, thereby preventing the loss of the fixative and facilitating subsequent demolding operations.

[0065] Please refer to Figures 3-4 , Figures 3-4 This is a schematic flowchart of a second embodiment of the method for preparing translucent concrete provided by the present invention. It is understood that, in order to achieve the effect of the light-guiding fiber preform remaining stable in the first cement mortar, the fixative should be a high-density fixing slurry, which can be various high-density resins, etc. However, in order to reduce the manufacturing cost of the light-guiding fiber preform and to facilitate the acquisition of its manufacturing materials, in this embodiment, the fixative is set as a second cement mortar. The specific operation steps of S30, where the fixative is introduced into the grouting groove 12 to fix and shape the light-guiding fiber to form the light-guiding fiber preform, are as follows:

[0066] S310 injects the second cement mortar into the plurality of grouting grooves 12 in the mold and performs air venting treatment on the second cement mortar;

[0067] After the second cement mortar in S320 has cured, it is demolded to form a light guide fiber preform.

[0068] The second cement mortar has a higher density than the first cement mortar, thereby increasing the overall density of the preformed optical fiber, so that the optical fiber preform remains stable in the first cement mortar.

[0069] In addition, to ensure good internal connectivity and strength during the molding of the optical fiber preform, before the step of demolding the second cement mortar after curing in step S320 to form the optical fiber preform, the following steps are also included:

[0070] S319 is used for film curing during the curing process of the second cement mortar.

[0071] During the curing process of the second cement mortar, it is covered with a film for curing so that the internal connection of the second cement mortar is more compact after curing.

[0072] It should be understood that the above are merely illustrative examples and do not constitute any limitation on the technical solutions of the present invention. In specific applications, those skilled in the art can make settings as needed, and the present invention does not impose any restrictions on this.

[0073] It should be noted that the workflow described above is merely illustrative and does not limit the scope of protection of this invention. In practical applications, those skilled in the art can select some or all of the workflow to achieve the purpose of this embodiment according to actual needs, and no restrictions are imposed here.

[0074] In addition, for technical details not described in detail in this embodiment, please refer to the smart watch control method provided in any embodiment of the present invention, which will not be repeated here.

[0075] Furthermore, it should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or system that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or system. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or system that includes that element.
