DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In the method of constructing a concrete wall according to the present invention, first, a hole is dug in a place to be constructed, gravel 10 is inserted as shown in FIG. 1, and then the periphery is surrounded by a wooden frame 11.

Then, the concrete is poured and the mixture shown in FIG.
As shown in, the base concrete 12 having a width of 300 mm and a depth of 50 to 100 mm is struck and the wooden frame 11 is removed. At this time, the base ends 13a ... Are embedded and some vertical lines 13 ...

Then, as shown in FIG. 3, the central hole 14a
The CR column 14 is erected on the base concrete 12 through the vertical bar 13. The CR support 14 is, as shown in FIG.
Concrete 1 is poured between the square frame-shaped outer mold 15 and the cylindrical inner mold 16 to form it by molding, and when the outer mold 15 is removed, the side faces 1 are opposite to each other as shown in FIG.
Panel holes 14c and 14c are formed in 4b and 14b, respectively, and the inner mold 16 made of an elastic material such as corrugated cardboard or rubber is left in the CR column 14 as it is after molding.

During molding of the CR column 14, the inner mold 16 is supported from inside and outside by appropriate means so that the inner mold 16 is not deformed by the weight of the poured concrete.

The panel hole 14c communicates with the center hole 14a and is formed on the side surface 14b on the side where the adjacent CR support 14 is located. Therefore, as shown in FIG. 5, the CR column 14 at the position where the CR columns 14 adjacent to each other on both sides are located is formed with the panel holes 14c on the side surfaces 14b, 14b opposite to each other as shown in FIG. However, since the CR columns 14 at both ends B and C do not have the adjacent CR columns 14 on the other side, unlike the CR columns 14 shown in FIG.
It is formed only on the side surface 14b on one side where the pillar 14 is located. In addition, as shown in FIG.
As shown in FIG. 5, the CR columns 14 are formed on the adjacent side surfaces 14b and 14b.

Thus, the panel holes 14 formed in the mutually opposing side surfaces 14b, 14b of the adjacent CR columns 14, 14.
In CR14c, one CR panel 17 made of concrete
Insert the ends of each of the CRs, as shown in FIG.
The CR panel 17 is supported between the columns 14 and 14. For example, the CR stanchions 14 and 14 at the positions a and b
One end 17a of one CR panel 17 is inserted into the panel hole 14c of the CR column 14 at the position a, and the CR column 14 at the position b is inserted.
The other end 17b is fitted into the panel hole 14c. Then, the end portion 17a.1 of the CR panel 17 is provided in the panel 14c.
When 7b is inserted, the inner mold 16 is deformed by pushing at its end. For example, as shown in FIG. 7, CR panels 17 are inserted from both sides into the CR column 14 at the position a, and the inner mold 16 having a cylindrical shape is deformed as illustrated.

As shown in FIG. 8, the CR panel 17 has a horizontally long rectangular shape, and first of all, on the front surface, stepped patterns 17a and 17b are formed on the upper and lower edges thereof so as to project outward in a stepwise manner. Further, columnar patterns 17c and 17d are formed by connecting the upper and lower stepped patterns 17a and 17b at positions equally divided into three parts on the right and left sides. Those columnar patterns 17c ・ 1
The planes 17e on the left and right of 7d are appropriately patterned. Further, as shown in FIG. 9, on the back surface, the horizontal clearance grooves 1 are provided just on the back sides of the stepped patterns 17a and 17b.
7f and 17g are provided, a top piece 17h is formed on the upper edge, and a bottom piece 17i is formed on the lower edge.

Then, concrete is poured into the deformed inner molds 16, 16 to fix the CR panels 17, 17. Then, as shown in FIG. 10, each CR support 17
A decorative top plate 18 is attached to each of them.

Then, the panel hole 14c and the CR panel 1
The caulking material is poured into the clearance b between the CR panel 1 and
A slight contraction of 7 makes it possible to move in and out of the panel hole 14c to hermetically seal between them.

Then, at the request of the client, a fence 19 is provided on the CR panel 17 as shown in FIG.
, And the top piece 17h is sandwiched and fastened with bolts and nuts. In this case, as shown in the figure, both ends of the fence 19 can be attached in advance to a tall C
It is necessary to use the R columns 14 and 14. If necessary, as shown in FIG. 12, the bottom piece 17i may be sandwiched and fastened with the bolt 20 and the nut 21 to securely fix the CR panel 17 on the base concrete 12.

The CR column 1 which is a concrete product
4 and CR panel 17 have a specific gravity of 1 by incorporating air bubbles
If it is about, for example, a CR panel 1 of about 2000 mm
If the number is 7, it can be sufficiently carried by less than two people, and the concrete fence described above can be easily constructed.

[0021]

As described above, according to the present invention, since the concrete fence is made by standing the CR columns on the base concrete and assembling the CR panels between them, there is no need to stack the blocks, and the strength is improved. Since it is strong and there is little danger of collapse due to an earthquake or the like, and because it is simply assembled, it does not require the skilled skills of craftsmen, and it is inexpensive and can be manufactured.

According to the second aspect of the present invention, the inner die is made of an elastic material and left in the CR column as it is after molding,
When the end of the CR panel is inserted into the panel hole, press the end to deform the inner mold and pour concrete into the deformed inner mold to fix the CR panel. Even if the CR panel expands and contracts, the expansion and contraction of the CR panel can be absorbed by the inner mold to prevent the CR panel and the CR column from cracking.

According to the third aspect, since the caulking material is poured into the gaps after the CR panels are fitted into the panel holes, the CR panels can expand and contract due to a temperature difference or the like. It is possible to seal between the panel hole and the CR panel.

According to the fourth aspect of the invention, since the fence is mounted on the CR panel, the taste can be further changed to increase the height of the fence, and the fence can be diversified easily. .
