[0033] When in use, the acrylic plate 2 can be punched as needed to form various patterns to meet different personalized and diversified needs, greatly improving the design, decorativeness and application of the translucent concrete in various scenes; the holes on the acrylic plate 2 are not drawn in the figure, and various plates can be selected for punching according to the concrete casting thickness and needs, which can further control and reduce costs; the position, size and number of the light-transmitting points of the translucent concrete can be accurately controlled, and the amount of light-guiding fiber can be accurately controlled, which is convenient for controlling costs; the four vertical plates 1 are connected to form a rectangular frame, and the vertical plates 1 and the acrylic plate 2 cooperate to form a mold, and a fixed long plate 4 is set on the vertical plate 1. When one end of the fixed long plate 4 on one vertical plate 1 is fixed to the other vertical plate 1 by bolts, a triangular stable structure is formed between the two vertical plates 1 and the fixed long plate 4, so that the connection between the vertical plates 1 is more stable, the structural connection strength is enhanced, and the stability and reliability of the mold as a whole are ensured. By assembling the mold, inserting the light-guiding fiber at a fixed point, and then pouring concrete to form it, the construction complexity of translucent concrete is greatly reduced. The streamlined construction process makes it more convenient for the preparation and construction of translucent concrete.

[0034] Furthermore, if Figure 1 and Figure 4 As shown, the head end of the vertical board 1 is provided with a connecting side board 6, and the side of the tail end of the vertical board 1 is provided with a side groove 11 that matches the connecting side board 6. When connecting, the connecting side board 6 on the vertical board 1 is inserted into the side groove 11 on another vertical board 1, and the connecting side board 6 is arranged to match the side groove 11 to ensure the reliability of the connection between the four vertical boards 1.

[0035] See also Figure 2 and Figure 3The figure shows the second embodiment of the mold of the present invention, a light-transmitting concrete mold, comprising: a vertical plate 1, an acrylic plate 2 and a fixed long plate 4; different from the first embodiment, the second embodiment also includes a top plate 3, which is arranged above the rectangular frame, and a second perforation is arranged on the top plate 3 corresponding to the first perforation, and the four sides of the top plate 3 are connected to the horizontal plate 31, and the bottom of the horizontal plate 31 is vertically connected to a vertical rod 5, and the vertical plate 1 is provided with a fixing groove for fixing the vertical rod 5.

The top plate 3 is arranged just above the rectangular frame and between the four vertical plates 1, so that there is enough space between the top plate 3 and the vertical plates 1, which is convenient for concrete pouring.

[0038] A method for preparing light-transmitting concrete, comprising the above-mentioned light-transmitting concrete mold, comprises the following steps:

[0039] Step 1: split the pattern into several circular holes with the same diameter;

[0040] Step 2, punching the acrylic plate 2 and the like, and assembling the light-transmitting concrete mold;

[0041] Step 3, inserting the optical fiber;

[0042] Step 4: preparing cement mortar and casting it into shape;

[0043] Step 5: After the molding and hardening, demoulding is carried out, the light-guiding fibers protruding from the surface of the translucent concrete are cut off, and a protective agent is applied.

[0044] Specifically, in step 1, according to the design requirements, graphic image or model design software is used to design the graphic pattern, the design pattern is split into a plurality of circular holes with the same aperture, the diameter of the circular hole is set according to the requirements, the distance between the centers of the circular holes is set, the deformation of the entire graphic pattern is corrected, and the overall pattern is harmonious and orderly. For example, the diameter of the circular hole is set to 6 mm, the distance between the centers of the circular holes is set to 15 mm, and the number of circular holes is calculated;

[0045] In step 2, first, the split design pattern is exported according to the proportion of the construction drawing, and the exported design drawing is imported into the CNC punching machine, and the punching aperture accuracy is set to 0-0.5mm, and then the acrylic plate 2 is punched. The thickness of the acrylic plate 2 is 2.8mm and the size is 1000mm×1000mm. After the punching is completed, the surface of the acrylic plate 2 is painted with a water-based release agent, and the translucent concrete mold is assembled. During assembly, the acrylic plate 2 is placed on a flat and non-inclined plane. The length of the vertical plate 1 is greater than 1000mm, and 1200mm is taken here, but the size of the internal assembly needs to be consistent with the size of the acrylic plate 2. The joints between the acrylic plate 2 and the vertical plate 1 can be sealed with glass glue;

[0046] In step 3, the mold is placed on a flat ground, a layer of insulation board is laid under the light-transmitting concrete mold, and the light-guide fiber is inserted into each circular hole on the corresponding acrylic board 2. The diameter of the light-guide fiber is 6 mm, and the lower end of the light-guide fiber needs to be inserted into the insulation board 0.5-1 cm, and the upper end is much higher than the vertical board 1, and a layer of release agent is applied to the light-transmitting concrete mold;

[0047] In step 4, firstly, cement mortar is prepared by uniformly mixing cement, fine sand, coarse sand, water reducing agent, defoaming agent, water, pigment, polypropylene fiber, etc. according to the designed dosage to obtain cement mortar. The mix ratio parameters are shown in the following table:

[0048] Material White cement Fine sand coarse sand Water reducing agent Defoaming agent water pigment Polypropylene fiber Single dosage 1000 600 400 5 2 270 50 0.9

[0049] Then, pouring and molding are performed. During pouring, the cement mortar can be poured in multiple layers. After each layer is poured, regular tamping or mechanical vibration is performed to remove the gas in the slurry. The cement mortar prepared in this embodiment is poured in two layers. The vibration frequency and time of the vibration table after each layer is poured are fixed. The first layer is poured at 1 / 2-2 / 3 of the height of the vertical plate 1. After the cement slurry is leveled in the light-transmitting concrete mold, the second layer is poured. After pouring, the concrete surface is scraped and leveled;

[0050] In step five, after the concrete is formed and hardened, it is demolded to obtain mirror-like translucent concrete. The molding surface is cut off with an angle mold machine to remove excess fiber, and the mold surface is cut off with a knife to remove excess fiber. Then, a protective agent is applied to the mold surface of the translucent concrete.

[0051] Other material boards can be selected to replace acrylic board 2, and various boards can be selected for punching according to the thickness and needs of concrete casting to further control and reduce costs. Through pattern splitting design, the position, size, and number of light-transmitting points of translucent concrete can be accurately controlled, which can achieve the effect of translucent concrete with many light-transmitting points but not messy, and orderly in chaos. Through precise control of the number and aperture of light-transmitting holes, the amount of light-guiding fiber can be accurately used, which is convenient for cost control. Through the split design of graphic patterns, regional style and personality customization can be carried out, which greatly improves the design, decorativeness, and application of translucent concrete in various scenes. Through pattern splitting design, punching template mold assembly, light-guiding fiber fixed-point insertion, and then pouring concrete to form, this greatly reduces the construction complexity of translucent concrete, and streamlined construction process makes it easier to prepare and construct translucent concrete.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
