EXAMPLES Examples of the wave-dissipating, root-setting, floor-stopping, revetment block and manufacturing method therefor according to the present invention will be described below. First of all, we will explain about wave-dissipating, rooting, and revetment blocks. Blocks (1) for wave breaking, consolidation and revetment are shown in Figures 1 to 4.
The body (2) is made of concrete as shown in
(2) has at least a flat plate portion (3).

The peripheral portion of the main body (2) is chamfered. The flat plate part (3) has a relatively thin plate shape, and the flat plate part (3)
Holes (not shown) for inserting lifting metal fittings may be drilled at both ends of this, and these holes may be filled with concrete before laying as shown in the drawings for aesthetic reasons. .
On the upper surface of the flat plate part (3) of this body (2), an arbitrary convex member (4)
Are embedded in an arbitrary array.

In the example shown in FIGS. 1 to 3, a pseudo-stone made of concrete is used as the convex member (4). The shape and arrangement method of the pseudo stones are arbitrary, and in the example of FIG. 1, two semi-circular pseudo stones are arranged in parallel on the flat plate portion (3). In the example of FIG. 2, five smaller pseudo stones are arranged, and in the example of FIG. 3, one square pseudo stone is placed. In the example of FIG. 4, a convex member
(4) Six natural stones are buried on the flat plate part (3). Natural stones having an aesthetic appearance are arbitrarily selected.

5 and 6 show a state in which a large number of the above blocks (1) are laid, and in FIG. 5 the block (1) on which a round pseudo stone is placed and in FIG. 6 natural stone is buried respectively. The blocks (1) are laid in close contact. In this laid state, circular pseudo-stones or boulder-shaped natural stones addressed to two as convex members (4) are aligned in parallel for six blocks per one block (1). An appearance is revealed. The block (1) according to the present invention has the effects of wave breaking, scour prevention, and water flow attenuation. Furthermore, although the side surface of this embodiment is flat, the side surface of the block (1) is provided with an uneven portion as in the conventional example, or the bottom of the flat plate portion (3) has a substantially E-shaped bottom view. You may form a part.

Next, a method of manufacturing the wave-dissipating, root-setting, floor-stop and revetment block will be described with reference to FIGS.
7 to 10 show a first embodiment of the block manufacturing method. The first embodiment is a manufacturing example in which the flat plate portion (3) is formed in the grounding direction at the time of manufacture, and the flat plate portion (3) is used as the top direction by reversing the top and bottom after curing and solidification. In this example, the surface mold (5) and the main mold (6) are used as molds. The surface mold (5) is a mold made of a substance that is hard to solidify, and soil cement is used in this embodiment. The surface mold (5) may be formed of a substance that is hard to solidify, for example, a clay-based material, or a foamed synthetic resin such as Styrofoam instead of soil cement. This shape is a flat plate, and the concave portion (7) for arranging the convex member (4) at a predetermined position
Are formed.

[0012] Soil cement is clay-like, has fluidity when water is added, and is a substance which hardly solidifies even when left standing, and therefore can be kneaded by hand. Therefore said recess (7)
Are manually created on-site according to the shape of the convex member (4) to be placed. 7 and 8 show an example in which the convex member (4) is a pseudo stone. First, a concave portion (7) having a shape corresponding to the shape of the pseudo stone is formed on the surface mold (5), and the concave portion (7) is formed. Place the pseudo stone, which is the convex member (4), on the. At this time, the upper part of the pseudolith in the drawing may be slightly projected from the upper surface of the surface mold (5).

Next, the main body mold (6) is arranged around the surface mold (5). This body formwork (6) has an open top and a bottom plate
A formwork having (8) and a side plate (9), which is erected from the peripheral edge of the bottom plate (8). The main frame (6) is surrounded so that its side plate (9) abuts on the peripheral edge of the surface mold (5). Then, concrete (10) is poured into the main body form (6) and cured in this state, and then the side plate (9) is removed to dismantle the main formwork (6). The part formed by the main body form (6) is the flat plate part (3).

In this state, since the bottom surface of the flat plate portion (3) is on the upper side, this is reversed so that the surface die (5) is on the upper side. Finally, the surface mold (5) is removed from the block (1). Since this surface mold (5) is made of soil cement, it prevents contamination by high pressure water (preferably washed soil cement (alkaline)). Therefore, the surface mold (5) is washed away by spraying acidic high-pressure water), and the convex member (4)
The wave-dissipating, embankment, and revetment block (1) embedded in the main body (2) is completed.

9 and 10 show examples in which natural stone is used as the convex member (4). Natural stone surface type
In order to place it in (5), if this natural stone is buried up to the bottom of the surface mold (5), the height of the natural stone will be the same after the block (1) is completed and it will look good.

A surface mold (5) in which natural stones are buried is arranged at the bottom of the main mold (6) as in the above, and concrete (10) is poured and cured in the main mold (6). Rear, body formwork
The block (1) as shown in FIG. 4 is completed by removing (6) and further washing off the surface mold (5). Further, in this embodiment, a water-impervious sheet may be laid on the upper surface of the surface mold (5) (not shown).
(10) Water inside is prevented from penetrating into soil cement. In this case, the sheet is formed with a hole through which the arranged natural stone can pass, and the natural stone is passed through this hole.

A second embodiment of the method of the present invention will be described with reference to FIGS. The second embodiment is different from the above-described first embodiment in that the flat plate portion (3) is manufactured so as to face up from the time of manufacture and is installed in this state. In this example, the form (11) shown in FIG. 11 is used, and the form (11) is constructed by assembling at least a bottom plate (12) and side plates (13) standing upright around the bottom plate (12). It becomes. 11 to 15 show an example in which pseudolite is used as the convex member (4). Concrete (10) is placed in the form (11) (see FIG. 12).

When the concrete (10) is solidified to some extent, the pseudo member as the convex member (4) is placed on it. The surface of the concrete (10) other than the part where the convex member (4) is placed is leveled with a trowel. In this state (state of FIG. 13), curing is performed for a while, and the formwork (11) is disassembled. In this case, FIG.
If the brim (4a) is formed on the bottom edge of the pseudo stone as shown, even if the pseudo stone is placed in a state where the concrete (10) is still slightly soft, the pseudo stone will unnecessarily immerse into the concrete (10). It is suppressed to go. Alternatively, by embedding reinforcing bars in concrete (10) and supporting the convex member (4),
It may be possible to prevent (4) from immersing in the concrete (10).

Further, in the present embodiment and the above-mentioned first embodiment,
When using a pseudo stone as the convex member (4), if a bar material (4b) as shown in FIG. 15 is projected from the bottom surface of the pseudo stone, the bar material (4b) is inserted into the concrete (10). As a result, the joint between the pseudo stone and the main body (2) can be strengthened.

FIGS. 15 and 16 show an example in which natural stone is used as the convex member (4) in the second embodiment.
In this example as well, the above-mentioned one is used as the formwork (11), concrete (10) is placed in this formwork (11), and when this concrete (10) has solidified to some extent, natural stones are arranged on it. , To cure. Alternatively, reinforcing bars may be embedded in the concrete (10) to support the convex member (4) to prevent the convex member (4) from sinking into the concrete (10). Once the concrete (10) has solidified, the form (11) may be dismantled. In any of the above-mentioned embodiments, vibration is applied at the time of placing concrete to remove air bubbles in the concrete.

[0021]

Since the present invention is constructed as described above, it has the following effects. In other words, because it is a wave-dissipating, root-blocking, floor-stop, and revetment block in which irregularities of any shape are arranged on the flat plate, regardless of whether it is natural stone or natural stone, it has an excellent appearance when laid on the coast or riverbank. You can freely show the installed state of the blocks.

Since the specific gravity of the natural stone of the convex member is usually heavier than that of concrete, embedding the natural stone in the block increases the stability of the block in the laid state.
Also, in order to manufacture this wave-dissipating, root-blocking, and revetment block, a surface mold made of a material that is hard to solidify is formed with a concave portion of an arbitrary shape on site, and pseudo stone or natural stone is placed in this concave portion, or simply Since it is only necessary to place pseudo-stones or natural stones on the concrete cast in the formwork, the on-site response is extremely easy.
