[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a columnar construction material capable of forming an outdoor wall-like body such as a retaining wall, a fence or a gate pole with good workability and improving its appearance.

[0002]

2. Description of the Related Art For example, a retaining wall for retaining soil or an outdoor wall-like body w such as a fence, which is necessary for embankment due to a difference in height between a road and a site, is usually as shown in FIG. , The concrete blocks a are arranged vertically and horizontally on the foundation f via mortar.

[0003]

However, in the case of using the concrete blocks a ..., the appearance tends to be monotonous and not only does not look good, but also a large number of concrete blocks a ... Since it is necessary to connect the wall-shaped body w through the above, it requires a lot of trouble and labor, and the workability of the construction of the wall-shaped body w is poor.

In particular, when the wall-shaped body w is curved as shown in FIG. 18, it is difficult to arrange the concrete blocks a ... In this curved portion, so that the workability is further deteriorated and the appearance is deteriorated. It becomes more prominent.

Regarding the concrete blocks a that are vertically stacked, although the concrete blocks a are reinforced by the reinforcing bars b planted in the foundation f, the concrete blocks a arranged side by side
Since the spaces are connected by using only mortar, the tendency that the strength of the wall-shaped body w becomes insufficient especially at the curved portion becomes large.

Further, since mortar is applied on a concrete block, dried, and color-finished, the mortar coating and its drying process, curing and painting process for painting are required, and the process is complicated. In addition, cracks due to joint cracks, stains on the painted surface, deterioration due to mold, etc. may occur and the landscape may be impaired.

The present invention is based on the fact that it has a long base which is fixed on a base foundation using reinforcing bars and concrete, and has good workability even if an outdoor wall is curved. The purpose is to provide columnar construction materials that can be made and that look and improve the landscape.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 to 11, the pillar-shaped construction material 1 of the present invention can be connected to each other by using the locking pieces 2 that are arranged side by side and extend in the lateral direction, and can be vertically erected so that the outdoor wall-shaped body W, the present embodiment. Then, the retaining wall A that serves as a soil stop at the time of embankment is formed.

As shown in FIGS. 1 to 4 and 7, etc., the columnar construction material 1 has a part of the inner surface of a vertically long vertical cylinder 3 having a diameter D of 10 cm or more and 30 cm or less, in this example, 20 cm. In the embodiment, an elongated base 4 having a notched tubular shape having notched edges E, E which are notched in parallel in the longitudinal direction over the entire length,
It comprises a pair of the locking pieces 2 and 2 which are integrally formed on the base portion 4 and project from the notched edges E, in a direction facing each other, and in which the projecting ends EA, EA are open.

When the diameter D is smaller than 10 cm, the number of columnar construction materials 1 required for forming the retaining wall A increases and the workability is deteriorated. On the other hand, when the diameter D exceeds 30 cm, the quality becomes excessive. Moreover, it may make it look bad.

The columnar construction material 1 is a pottery material such as a clay pipe or a porcelain material, a concrete molding material finished in a factory, a foam thereof, or a granular material using an adhesive.

With respect to the pair of first groove portions 6 and 6 that are recessed, and the pair of second groove portions 7 and 7 that are integrally formed inwardly of the first groove portions 6 and 6 and are opposed to each other, For example, it is a bent body of a metal plate having projecting pieces 20 extending in the opposite direction, and an inner piece 21 connecting between 20 in an arc shape.

It should be noted that a shield 22 having the same cross-sectional shape as the connecting tool 5 having the first and second groove portions 6 and 7 but having a height smaller than that of the connecting tool 5 is used. As shown in FIG. 3, the lower part of the open portion 23 between the projecting ends EA of the two locking pieces 2 and 2 of the columnar construction material 1 and EA is shielded. That is,
When the names and symbols of the respective parts of the shield 22 are expressed the same as those of the connector 5, the protruding ends E of the locking pieces 2 and 2 are provided in the second groove parts 7 and 7.
A and EA are fitted to each other, so that the shield 22 is attached to the columnar construction material 1.

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

That is, the length L2 between the projecting 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 and 2 in one columnar construction material 1 and the cutout edge E, It is smaller than the length L3 (= 2Rcos α) between E.

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