Therefore, in the present invention, a single transparent body 3 is used as one transparent body unit 10, and an assembly of several transparent bodies 3 is also used as one transparent body unit 10. Further, the size of the transparent body unit 10 can be freely set.

  Next, the first step will be described with reference to FIGS. The first step is a step of manufacturing the transparent body unit 10 in which the transparent body 3 is fixed so as to form the determined pattern. Although an example of the manufacturing method of the transparent body unit 10 in a 1st process is shown, it is not limited to the following method.

  In order to form a pattern on both sides of the concrete body 1, the transparent body 3 having a length substantially the same as the thickness of the concrete body 1 is used, and in order to form a pattern on one side of the concrete body 1, the concrete body A transparent body 3 having a length shorter than 1 is used.

  First, a support member 31 that supports the lower end portion of the transparent body 3 by holding it on the upper surface of the horizontal base 30 is fixed. The shape of the support material 31 is a support material having a shape corresponding to the cross-sectional shape of the transparent body. For example, a U-shaped support material 31 capable of holding an object having a rectangular cross section if it is a plate shape, and a cylindrical support material 31 that can hold an object having a circular cross section if it is a columnar shape. .

  Next, four side plates 33 are erected on the upper surface of the base 30 to form the frame body 32. Then, the lower mold plate 36 provided with a plurality of holes (not shown) through which the transparent body 3 erected by the support material 31 is inserted is installed at an arbitrary height. Then, the lower mold plate 36 is reinforced by, for example, installing an inner pier 35 below the lower mold plate 36 so that the lower mold plate 36 is not displaced or deformed by the weight of the fixing material 41 or the like. A thin film (for example, a vinyl sheet 37) having a material and a thickness that is not damaged by the fixing material 41 so that the fixing material 41 does not leak due to the pouring of the fixing material 41 over the entire surface of the lower mold plate 36. ) Is placed.

  Next, the transparent body 3 is inserted into the hole of the lower mold plate 36, and the lower end portion of the transparent body 3 is sandwiched and fixed by the support material 31. Then, as shown in FIG. 4, at the intermediate position between the line connecting the outer peripheral portion of the transparent body 3 and the outer peripheral surface of the fixing material 41 to be poured, the wire 40 is surrounded so as to surround all the disposed transparent bodies 3. The ring-shaped and cross-shaped number lines 40 are connected to each other by a number line 40 that is arranged in a ring shape and has a cross shape with the center point of the number line 40 arranged in the ring shape as an intersection. Thereby, the crack of the solidified fixing material 41 can be prevented. Further, at least one number wire 13 is arranged such that one end of the number wire 13 is connected to the annular number wire 40 and the other end is in a free state.

  And when pouring the fixing material 41, the height of the number wire 40 is adjusted so that the said number wire 40 is arrange | positioned in the intermediate position of the thickness direction of the fixing material 41 after hardening.

  Next, a water-stopping material 42 that stops permeated water such as resin, rubber, water-impermeable clay, and the like is put on the outer peripheral surface of the transparent body 3. If the water-stopping material 42 is used, water-stopping measures can be doubled. However, the water-stopping material 42 does not need to be used because it has a water-stopping effect even if the water-stopping material 42 is not used. The work of attaching the water blocking material 42 to the outer peripheral surface of the transparent body 3 is performed before the transparent body 3 is inserted into the lower mold plate 36 or at a stage after the transparent body unit 10 is completed. May be.

  Next, in order to reduce the input amount of the fixing material 41 and realize the weight reduction of the transparent body unit 10, a thin film (on the side plate 33 of the frame body 32) placed on the lower mold plate 36 ( For example, on the vinyl sheet 37), for example, a triangular object in a plan view is arranged at the four corners of the frame 32, or a flat plate-like object having a hole surrounding all the glass plates 12 is provided in the frame 32. Or place it inside. Here, the shape of the object for reducing the input amount of the fixing material 41 installed in the frame 32 is not limited.
