An embodiment of the present invention will be described below with reference to the drawings. 1 to 11, a columnar construction material 1 according to the present invention can be connected to each other by using a locking piece 2 which is arranged side by side and extends sideways, and is vertically erected to form an outdoor wall-shaped body W, which is an embodiment of the present invention. Then, a retaining wall A which serves as a barrier for embankment is formed.

As shown in FIGS. 1-4 and 7, etc., the columnar construction material 1 is a part of the inner surface of a vertically long cylindrical body 3 having a diameter D of 10 cm or more and 30 cm or less, in this example, 20 cm. In the embodiment, a notch tube E having a notch edge E, E that is notch parallel and notch continuously in the longitudinal direction over the entire length,
The base 4 is formed of a pair of locking pieces 2, 2 which are formed integrally with each other and protrude from the notch edges E, in a direction facing each other, and have a protruding end EA.

If the diameter D is smaller than 10 cm, the number of columnar construction materials 1 necessary for forming the retaining wall A increases, and the workability is reduced. On the other hand, if the diameter D exceeds 30 cm, excessive quality results. In addition, the appearance may be deteriorated.

The columnar construction material 1 is made of a ceramic material such as an earthen pipe or a porcelain material, a concrete molding material finished in a factory or the like, a foamed material thereof, and a granular material using an adhesive.
It is formed of a powdery substance combination or the like, and its appearance is improved by its gloss and the like.

Such a columnar construction material 1 comprises a foundation foundation F
A connecting tool 5 for connecting the columnar construction materials 1 , 1 that are placed side by side on the top and vertically erected and that are side by side . As described above, the “connecting tool 5” is a columnar construction material.
1, but for convenience of explanation,
What consists of the base 4 and the locking pieces 2, especially columnar construction
It is referred to as a material 1 and the connecting member 5 is made of this columnar construction material.
1 and 1 are represented as members for connecting.

As shown in FIGS. 2 and 4, the connecting member 5 is opposite to the direction in which the adjacent locking pieces 2, 2 of the columnar construction materials 1, 1 arranged side by side are fitted and face each other. A pair of recessed first grooves 6, 6 and a pair of second grooves 7, 7 integrally formed inside and facing each other, and a pair of second grooves 7, 7 integrally formed inside and facing each other. It is made of, for example, a bent metal plate having a projecting piece 20 extending in the opposite direction, and an inner piece 21 joining in an arc shape between the projecting pieces 20.

2 and FIG. 3 using a shield 22 having the same cross-sectional shape and a smaller height than the connector 5 having the first and second two grooves 6 and 7. As shown in FIG. 3, the lower part of the opening 23 between the projecting ends EA, EA of the two locking pieces 2, 2 of the columnar construction material 1 is shielded. That is,
If the names and symbols of the respective parts of the shielding tool 22 are expressed in the same manner as the connecting tool 5, the protruding ends E of the locking pieces 2, 2 are provided in the second grooves 7, 7.
A and EA are fitted, whereby the shield 22 is attached to the columnar construction material 1.

Here, the radius R of the cylindrical body 3 (= D / 2),
The length L of the locking piece 2 and the cylindrical body 3 passing through the notch edge E
The relationship between the radius line RL and the horizontal angle SL of the columnar construction material 1 and the horizontal line SL parallel to the locking piece 2 (all of which are shown in FIG. 3) is regulated as follows.

That is, the length L2 between the protruding ends EA, EA of the adjacent locking pieces 2, 2 of the adjacent columnar construction materials 1, 1
(= 2R-2Rcos α + 2L) is larger than the length L1 (= 2Rcos α-2L) between the protruding ends EA, EA of the locking pieces 2, 2 in one columnar construction material 1 and the notch edge E, It is smaller than the length L3 between E (= 2Rcos α).

That is, L1 <L2 <L3. By transforming this, the following inequality is obtained. (R + L) / 2R <cos α <(R + 2L) / 2R (1)

The value of L / R is set to 0.10 or more and 0.30
The following is assumed. By limiting the value of L / R and determining the angle α so as to satisfy the inequality (1) in this manner, as shown in FIG. 3 and FIG. The cross-sectional shape of the tool 22 can be formed such that, for example, the inner piece 21 approaches the virtual arc of the cylindrical body 3, and furthermore, the work of fitting the locking piece 2 by the first and second grooves 6, 7 is facilitated. .

When the length L2 becomes equal to or less than the length L1, the second groove portions 7, 7 are greatly bulged to lock the shield 22 to the locking pieces 2, 2, and the inner piece 21 When the columnar construction materials 1 and 1 are connected by the connecting tool 5 having the same shape as the cross section, the adjacent connecting tools 5 and 5 are located inside the opening 23. There is a possibility of collision, which may reduce the effect of the connecting member 5 to prevent the columnar construction material 1 from fluctuating.

When the length L2 is equal to or longer than the length L3, the first and second grooves 6, 7 need to be largely bent when the shield 22 is locked to the locking pieces 2, 2. The mounting work tends to be difficult.

FIG. 5 shows the columnar construction materials 1, 1 arranged side by side.
6 shows a case where it is arranged to be bent inward, and FIG. 6 shows a case where it is arranged to be bent outward.

FIG. 5, even in any state of FIG. 6, if fabricated columnar construction material 1 so as to satisfy the inequality (1), columnar construction materials 1 arranged in the horizontal with the connecting member 5 , 1
