Next, an embodiment of the present invention will be described with reference to the drawings.
In FIG. 1, A is a fence, which is composed of a fence foundation portion 1 and a fence portion 2.
The wall foundation portion 1 is configured by arranging a required number of foundation blocks 3 side by side in a row, and is installed on the crushed stone foundation 6.
The plurality of foundation blocks 3 and 3 are connected to each other by appropriate connecting metal fittings. When the foundation block 3 is installed, the portion below the ground GL becomes the foundation portion 3a, and the portion above the ground GL becomes the decorative surface 3b.
The fence portion 2 includes a support column 4 and a face material 5. An appropriate number of columns 4 are erected on the upper surface of the wall foundation 1. The plurality of face materials 5 are supported by columns 4 and 4.
In the present invention, the wall foundation portion 1 can have an arbitrary configuration, and the configuration of the fence portion 2 is characteristic.

The face material 5 used for the fence portion 2 of the present embodiment is a long plate material as shown in FIGS. 1 and 2. The material, thickness, and width of the face material 5 can be arbitrarily selected. The length of the face material 5 may be adjusted to the distance between the columns 4 and 4.

The configuration of the support column 4 will be described with reference to FIGS. 4 and 5.
The column 4 includes a columnar column 41 and a holding metal fitting 43 combined with the column 41.
A holding groove 42 is formed on the side surface of the pillar 41 to fit and hold the end portion of the face material 5. When the face material 5 is arranged on one side of the support column 4, the holding groove 42 may be formed on one side of the pillar body 41, and when the face material 5 is arranged on both sides of the support column 4, the face material 5 is held on both sides of the pillar body 41. The groove 42 may be formed.
The holding groove 42 is formed so as to be inclined on the side surface of the pillar 41, and the upper end is opened and the lower end is closed. With this structure, the face material 5 can be dropped and fitted into the pillar 41.

The inclination angle of the holding groove 42 is arbitrary, but is generally 55 ° to 90 ° with respect to the horizon. If it is inclined in this range, it is possible to improve ventilation while being able to blindfold with the face material 5.
The number of holding grooves 42 is matched to the number of face materials 5 to be attached. In the illustrated example, the number is 7, but 6 or less and 8 or more are included in the present invention.

In the support column 4 shown in FIG. 1, the holding groove 42 is formed on both side surfaces of the column body 41. This is to support the face material 5 together with another support column 4 on both sides of the support column 4. The support column 4 used at the end of the wall may be provided with a holding groove 42 on only one side, or may be provided with holding grooves 42 on both sides.

The holding metal fitting 43 is a metal fitting attached to the pillar body 41 to prevent the face material 5 fitted in the holding groove 42 from coming off.
As shown in FIG. 6, the holding metal fitting 43 uses an angle material having an L-shaped cross section, and a recessed groove 44 is formed on one side of the angle material.
The lower end of the fitting groove 44 is open and the upper end is closed. The fitting groove 44 is inclined, and the inclination angle thereof is the same as that of the holding groove 42 of the support column 4.
Several screw insertion holes 45 are provided on the other surface of the angle material, and screws can be inserted through the screw insertion holes 45 to fix the holding metal fitting 43 to the pillar 41 of the support column 4.

Next, the construction method of the fence portion 2 will be described with reference to FIGS. 4 and 5.
First, the support column 4 is erected on the foundation block 3. For the erection of the support column 4, a method of inserting the root pipe of the support column 4 into the hole formed in the foundation block 3 and solidifying it with cement is generally used, but the method is not limited to this method and any method can be adopted.

Then, the end portion of the face material 5 is inserted into the holding groove 42 of the erected support column 4. FIG. 5 shows a state in which the three face materials 5 on the lower stage side are inserted and the fourth face material 5 from the lower stage is inserted. Although only one support column 4 is shown in FIG. 5, another support column is actually prepared so that both ends of the face material 5 can be supported.
If the face material 5 is inserted through the opening at the upper end of the holding groove 42, the face material 5 stops at the closed lower end, so that the face material 5 can be held simply by inserting the face material 5, and since the holding groove 42 is tilted, the face material 5 is tilted. Can be held at.

When all the face materials 5 are inserted into the two columns 4 and 4, the holding metal fitting 43 is fitted so as to cover the upper part of the face materials 5. The support column 4 shown in FIG. 4 shows a state in which the holding metal fitting 43 is fixed to the pillar body 41 without showing the face material 5 on the left side, and a state in which the holding metal fitting 43 is fixed to the pillar body 41 showing the face material 5 on the right side. Is shown.

When the construction is carried out as described above, as shown in FIGS. 1 and 3, the face material 5 is restrained by the holding metal fitting 43 so as not to come off. That is, if the holding metal fitting 43 is attached with the face material 5 inserted in the holding groove 42 of the support column 4, the face material can be prevented from coming off, so that the face material can be used safely for a long period of time.

In the present invention, by using the holding grooves 42 on both side surfaces of the support column 4, the face material can be held on both sides of the support column, and if the support columns 4 are erected at intervals, the face material 5 can be continuously provided and laterally. The long fence portion 2 can be easily constructed.
When the face material 5 is long, it is possible to prevent the face material 5 from hanging down by connecting the plurality of face materials 5 to each other with metal fittings. The shape and structure of the metal fittings used for this purpose are arbitrary and are not limited.

When the face material 5 is dirty or damaged, the fence portion 2 according to the present embodiment can be easily replaced by simply removing the face material 5 from the holding groove 42 of the support column 4 and inserting a new face material 5. Therefore, it is possible to maintain the aesthetic appearance for a long period of time.

The details of the wall foundation 1 will also be described.
As shown in FIGS. 1 and 3, the foundation block 3 includes a vertical wall 10 and a bottom slab portion 20. The standing wall 10 is a member that rises upward with a predetermined thickness, and is divided into a decorative surface 3b and a foundation portion 3a as described above.
The bottom plate portion 20 is a member formed so as to project from the lower end portion of the vertical wall 10 to the back side, and is also called a footing.

On the upper surface of the bottom plate portion 20, mounting portions 21 for mounting the weight block 30, which will be described later, are formed at intervals in the lateral direction. In addition, a regulation wall 22 stands up between the individual mounting portions 21.
The regulation wall 22 has a trapezoidal cross section and extends in the depth direction on the bottom plate portion 20. The distance between the adjacent regulation walls 22 and 22 is set to be slightly wider than the width dimension of the weight block 30.

The weight block 30 is a block for adding weight to the foundation block 3. The shape and dimensions may be matched to the mounting portion 21 of the foundation block 3. Alternatively, the weight block 30 may have an arbitrary shape and weight, and the shape and dimensions of the mounting portion 21 of the foundation block 3 may be matched with the weight block 30. The point is that the foundation block 3 and the weight block 30 are separate members, and their shapes are not limited to those shown in the figure.

As shown in FIG. 2, the weight block 30 is an inverted L-shaped concrete member in a side view, a quadrangle in a plan view, and a quadrangle in a back view.
As shown in FIG. 3, when the weight block 30 is placed on the mounting portion 21, it fits between the regulation walls 22 and 22 on both sides and is immovably restrained in the left-right direction as shown in FIG.
When restrained in the left-right direction in this way, the weight block 30 is less likely to come off in the back direction as well.

As shown in FIGS. 1 and 3, the weight block 30 is formed with a vertically oriented first bolt hole 31, and the mounting portion 21 of the foundation block 3 is also formed with a vertically oriented second bolt hole 23. .. The two bolt holes 31 and 23 are formed so as to be coaxial when the weight block 30 is placed on the mounting portion 21. The combination of the first and second bolt holes 31 and 23 corresponds to the bolt holes in the claims.
As shown in FIG. 3, when the anchor bolt 32 is passed through the first bolt hole 31 and the second bolt hole 23 and hardened with cement, the weight block 30 can be firmly fixed on the foundation block 3.

Since the foundation block 3 is separated from the weight block, the foundation block 3 and the weight block 30 can be maintained in a small size and light weight even if the entire wall is enlarged. Therefore, construction can be performed even in a narrow space using a small heavy machine.
