DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit for building a wall and a method of manufacturing the unit for building a wall.

[0002]

2. Description of the Related Art Construction methods for walls, for example, seawalls (including seabeds), include a natural structure as a wall construction unit on seawalls, etc., in order to grow plants early and form fish nests. There are those that lay a large number of stone holding units. In each of the natural stone holding units, a plurality of natural stones are bonded on a flexible sheet body via an adhesive, and if this natural stone holding unit is used, the natural stone can be returned to the natural early stage. In addition to being able to transport natural stones to revetment slopes etc., natural stones fall down from revetment slopes after transportation even if the revetment slopes are steep. That can be prevented. This makes it possible to improve the workability of the revetment and the like, and to maintain the revetment after the construction for a long period of time.

The inventor of the present invention uses a concrete block in place of the natural stone bonded to the above-mentioned flexible sheet in order to improve the transportability based on cost reduction and weight reduction. Are thinking.

[0004]

However, as described above, when a concrete block is used in place of natural stone, the adhesive between the surface of the concrete block and the surface of the flexible sheet body. Therefore, the holding force between the flexible sheet body and the concrete block must be low due to the brittle nature of the surface of the concrete block. This tendency is further promoted when the flexible sheet is brittle.

In addition, since the flexible sheet body and each concrete block must be adhered to each other by using an adhesive, a sticky adhesive must be handled in the bonding operation (manufacturing). Alternatively, after arranging a plurality of concrete blocks on a flexible sheet body in consideration of balance, etc., each concrete block is once lifted, and an adhesive is applied to each of the concrete blocks. It must be inserted between the sheet and the sheet body, and the workability at the time of manufacturing is not easy.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and a first object of the present invention is to provide, when a concrete block is used, a holding force between the concrete block and the flexible sheet member. It is an object of the present invention to provide a unit for constructing a wall body, which can enhance the workability in manufacturing and can improve the workability. A second object is to provide a method of manufacturing the above-mentioned wall building unit.

[0007]

In order to achieve the first object, according to the first aspect of the present invention, a plurality of concrete blocks are arranged on a mesh piece on one side of the mesh piece. Each concrete block is hardened in a state of wrapping around the place where each concrete block of the mesh piece is located, and each concrete block is made to resemble a natural stone shape. It is configured as a unit for building a wall.

Further, the preferred embodiments of the first aspect of the present invention are as described in the second and third aspects.

According to another aspect of the present invention, there is provided a semiconductor device comprising:
According to the invention, the mesh piece is arranged on the work surface in a substantially horizontal state, a mold is arranged on the mesh piece, concrete is put in the mold, and then the mold is formed. A method for manufacturing a wall-building unit, comprising: removing a frame before curing the concrete so that only the uncured concrete block is placed on the upper surface of the mesh piece. There is a configuration.

[0010] Further, a preferred embodiment of the invention of claim 4 is as described in claim 5 or later.

[0011]

According to the first aspect of the present invention, on the mesh piece,
A plurality of concrete blocks are arranged on one side of the mesh piece, and each of the concrete blocks is hardened in a state of wrapping around the concrete block of the mesh piece.
Since the flexible sheet body is a mesh piece, it is not necessary to consider the brittleness of the flexible sheet body, but such a mesh piece may enter the inside of the concrete block. Thus, the holding force between the mesh piece and the concrete block can be improved. Moreover, concrete
When the wall building unit is obtained from the use of the block, the uncured concrete block is placed on the mesh piece, and a part of the concrete block is caused to flow to the other side of the mesh piece through the mesh of the mesh piece. With these, it is possible to wrap around the portion where the concrete block is located in the net-like piece.
The concrete block hardens, and the above-mentioned holding relationship between the concrete block and the mesh piece is obtained. For this reason,
In production, there is no need to handle the adhesive, and the work involved is eliminated. As a result, workability in manufacturing can be improved.

Further, since each concrete block is made to resemble the shape of natural stone, it is possible to suppress the outflow of the covering soil based on the irregular shape that is in harmony with nature, and to cause a sense of discomfort. Can be reduced.

According to the second aspect of the present invention, a plurality of stones are exposed on the surface of each concrete block. It can be shown and can be naturally harmonized while reducing costs and the like.

According to the third aspect of the present invention, since a plurality of stones are also included in the interior of the concrete block, not only the same operation and effect as in the second aspect can be obtained, but also the weight of the stone increases. Thereby, the laying stability and the like can be improved.

According to the fourth aspect of the present invention, the mesh piece is disposed substantially horizontally on the work surface, a mold is provided on the mesh piece, and concrete is inserted into the mold. Thereafter, the mold is removed before the hardening of the concrete so that only the unhardened concrete block is placed on the upper surface of the mesh piece. The uncured concrete block is caused to flow to the lower surface side of the mesh block based on its own weight, so that the lower portion of the uncured concrete block can wrap the mesh portion in the region below the concrete block. After the curing, the concrete block and the mesh piece can be firmly held. At the same time, the regulation of the mold is removed, and the uncured concrete block collapses in the horizontal direction or the like due to its own weight, and the concrete block has a shape close to natural stone.
For this reason, the wall construction unit according to claim 1 can be reliably obtained by a simple operation of merely placing the uncured concrete block on the upper surface of the net-like piece. In addition, since only the timing of removing the mold frame needs to be considered in the manufacture, the manufacture can be made extremely easy.

Is covered with the uncured concrete block while sinking, and a plurality of stones are exposed on the surface of the concrete block, so that the wall building unit according to claim 2 can be obtained. Become. In addition, since only the surface of the concrete block is covered with the stone, the amount of the stone used can be reduced as much as possible, which can be effective from the viewpoint of cost reduction and the like.

According to the sixth aspect of the present invention, since a plurality of stones are put in a mold together with the concrete in a kneaded state, after the concrete is hardened, the plurality of stones are placed on the surface of the concrete block. Not only the inside but also the inside, so that the wall construction unit according to claim 3 can be obtained.

According to the present invention, a concrete curing inhibitor is applied to the inner surface of the mold before the concrete is introduced into the mold, and after the mold is removed, the uncured concrete is removed. The semi-cured concrete is washed out after waiting for the semi-cured concrete block, so that the mold can be easily removed by the concrete curing inhibitor, while the concrete adhered to the uncured concrete block or the like. -The hardening inhibitor can be easily removed to make the natural stone group appear in appearance.

[0019]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 5 show a first embodiment. In FIG. 1, reference numeral 1 denotes a seawall as a wall, and in this embodiment, the seawall 1 is a seawall slope 2 as a lower side area 2 a and an upper side area 2 b
And an intermediate region 2c having a horizontal upper surface and continuously connecting the lower region 2a and the upper region 2b. The intermediate region 2c is set assuming the low water level L1 of the river 3 or the like, and the lower region 2a is to be positioned lower than the low water level L1. On the other hand, the upper side area 2b is located above the low water level L1, and the upper part thereof is located further above the high water level L2 of the river 3 or the like.

On the revetment slope 2, as shown in FIG.
In the intermediate area 2c and the upper area 2b, a large number of concrete block holding units 4 as units for building a wall are laid. Middle area 2c of revetment slope 2
And in the upper side area 2b, it is for constructing a substantial revetment. As shown in FIG. 2, each concrete block holding unit 4 has a plurality of concrete blocks 6 arranged on a wire mesh 5 as a mesh piece on the front side (one side) of the wire mesh 5. The concrete block 6 is a concrete block 6 of the wire mesh 5.
Are hardened in a state of wrapping around the area where is located.

More specifically, the wire mesh 5 is formed in a rectangular shape (in this embodiment, a square shape with a side of about 2 m), and a frame line (not shown) is provided at a peripheral portion thereof. Inside, a mesh 8a is formed by crossing a plurality of wires 8. Each wire 8
In the present embodiment, as shown in FIG. 3, one having a circular cross section is used, and the lower half of each wire 8 or the like has a width (length in the left-right direction in FIG. 3) as it goes upward. (The corresponding portion is indicated by an arrow in FIG. 3). Of course, instead of such a wire mesh 5, a synthetic resin net or wire is stretched horizontally within the frame to form a mesh 8a or mesh, a cloth material such as a woven fabric or a nonwoven fabric, or a vinyl fabric. -The above-mentioned net-like piece may be laminated on the sheet.

As shown in FIG. 2, each of the concrete blocks 6 has a shape as close as possible to the shape of natural stone, and each of the concrete blocks 6 has an irregular shape. ing. Also, the lower part (cured part) 9 of each concrete block 6
Reaches the back side (the other side) of the wire mesh 5 through the mesh 8a of the wire mesh 5 and wraps each wire 8 of the wire mesh 5, whereby each concrete block 6 becomes a wire mesh. 5 is to be held firmly.

In this case, the circular cross section of the wire 8 of the wire mesh 5 also contributes to making the concrete block 6 hard to come off from the wire mesh 5. That is, the circular shape of the cross section of the wire 8 in the wire mesh 5 is such that its width (length in the left-right direction in FIG. 3) gradually increases in the lower half as it goes upward, so that it has The concrete block 6 has a physical locking relationship with a wide locking surface. In particular, as shown by the imaginary line in FIG. 3, even when the wrapping of the wire 8 of the wire mesh 5 by the concrete block 6 is not complete,
The locking relationship between the two 8 and 9 ensures that the concrete block 6 is held by the wire mesh 5. Of course, as long as such a function is exerted, it goes without saying that the cross section of the wire 8 may be other than circular.

Such a concrete block holding unit 4 is specifically manufactured as shown in FIGS. That is, first, the wire mesh 5 is placed on the horizontal work surface 11 a of the work table 11. This is because the wire net 5 is placed in a horizontal state and work is performed under that state.

In this case, the work surface 11a is preferably a release surface having good releasability, and a release sheet may be laid on the work table 11 to secure the releasability. Wire mesh 5
Is based on the fact that the diameter of the frame wire is larger than the diameter of the internal wire 8, and in the present embodiment, the wire 8 area is slightly separated from the work surface 11 a based on the fact that the wire 8 is knitted. It has become.

Next, a mold 13 for each concrete block 6 is placed on the wire netting 5, and an uncured concrete 12 is put in each mold 13 as shown in FIG. Can be It forms a mass of uncured concrete 12 and, based on its own weight, uncured concrete 12
Through the mesh 8a of the wire mesh 5 so as to protrude to the back side (the other side) so that the concrete 12 wraps around the wire mesh 5 in the region below the concrete 12. At this time, as described above, the wire 8 region of the wire mesh 5 is slightly separated from the work surface 11a, and a slight space is provided below the wire 8 region.
The uncured concrete 12 enters the space, and the concrete 12 completely encloses the wire mesh 5. In addition, the outer surface of the uncured concrete 12 that has entered the back side of the wire mesh 5 is formed to be substantially flat by the work surface 11a. In this case, as the mold 13, a cylindrical one that narrows upwards is used in consideration of smooth removal of the mold 13. Of course, the molds 13 are not limited to individual ones, but may be ones in which the molds 13 are integrated. This makes it possible to improve the workability such as the arrangement of the mold 13 with respect to the wire mesh 5 and the removal of the mold 13.

Next, as shown in FIG.
It is removed when the concrete 12 is uncured and still soft. The restriction of the mold 13 with respect to the uncured concrete 12 is eliminated, and the uncured concrete 12 is deformed in the horizontal direction or the like based on its own weight, and the viscosity of the concrete 12 and the curing speed are balanced. This is for curing in a shape, that is, a shape close to natural stone.

As a result, a plurality of concrete blocks 6 each having a shape close to natural stone (for example, a rounded shape) are held on the wire mesh 5, and the concrete block holding unit 4 as a product is completed. . Of course, in this case, the concrete portion surrounding the wire mesh 5 is also hardened, and the hardened portion 9 firmly holds the concrete block 6 with respect to the wire mesh 5.

The explanation will be returned to the revetment 1. At the time of laying, such a large number of concrete block holding units 4 are connected to adjacent concrete block 6 units via a connecting member 16 as shown in FIG. On top of unit 4,
Covering soil 20 is piled up. The cover 20 is used to return to the natural environment at an early stage to secure an area for a walk or the like, and to hide the concrete block holding unit 4 to improve the appearance. In this case, the cover soil 20 is located above the low water level L1 of the river 3 or the like, and the cover soil 20 is usually hard to be washed away by flowing water.

As shown in FIG. 1, on the revetment slope 2
In the lower side area 2a, a large number of natural stone holding units 21 are laid as wall building units. This is to always prevent the soil from being removed by the flowing water at the low water level L1 where the flowing water exists, and to ensure a naturally harmonious appearance. Each of the natural stone holding units 21 is provided with a plurality of natural stones 2 on the surface of the wire mesh 5 with an adhesive.
The natural stone holding units 21 adjacent to each other are connected via a connecting member 16 as in the case of the concrete block holding unit 4. Such a large number of natural stone holding units 21 form an inclined surface that is continuous with the surface of the covering soil 20, so that a walk or the like can be easily performed between the surface area of the covering soil 20 and the natural stone holding unit 21. ing.

In FIG. 1, reference numeral 23 denotes a suction prevention seal.
The suction-prevention sheet 23 is laid on the revetment slope 2 before the concrete block holding unit 4 and the natural stone holding unit 21 are laid to prevent the suction of soil and the like. This suction prevention sheet 23
Is relatively thin, and for convenience, the line of the revetment slope 2 is also used.

FIGS. 6 and 7 show a second embodiment, FIGS.
Shows a third embodiment. In each of the embodiments, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

In the second embodiment shown in FIGS. 6 and 7, the concrete block 6 according to the first embodiment has many pebbles, crushed stones or the like singly or mixed together (hereinafter referred to as pebbles or the like). 31) is added. That is, in the second embodiment, as shown in FIG.
Uncured soft concrete 12 from which mold 13 has been removed
In response, pebbles 31 are scattered. Thus, the pebbles 31 cover the surface of the concrete 12 while partially sinking into the uncured concrete 12, and in this state, the concrete 12 is cured, and FIG.
As shown in the figure, a concrete whose surface is covered with pebbles 31
Block 6 will be obtained. Of course, at this time, the uncured concrete 12 is not only deformed based on its own weight, but also deformed toward a shape close to a natural stone shape due to scattering of pebbles 31 or the like.

As a result, even though almost all of the concrete 12 is used, it can be made to look like a group of natural stones in appearance, and the cost and workability can be remarkably improved.
It will be able to harmonize naturally.

In the third embodiment shown in FIGS. 8 to 10, the workability is improved and pebbles 31 are provided not only on the surface of the concrete block 6 but also inside. In the production of the concrete block 6, first, as shown in FIG. 8, a mold 13 having an inner surface coated with a concrete hardening inhibitor 32 such as a solvent or a solvent is placed on the wire netting 5, and the mold is formed. A kneaded material obtained by kneading the pebbles 31 and the concrete 12 is filled in the frame 13. Next, as shown in FIG. 9, while the concrete 12 is uncured,
The mold 13 is removed, and as described above, the concrete 12 collapses into a natural stone shape and waits for the concrete 12 to be in a semi-cured state. When the concrete 12 is in a semi-cured state, as shown in FIG. 10, water 33 is injected into the surface of the semi-cured concrete 12 and the like.
The hardening inhibitor 32 on the surface of the concrete 12 or the like (shown by a hatched area in FIG. 10) is washed away (washing out method), and the concrete 12 is waited for complete hardening. As a result, similarly to the second embodiment, a concrete provided with a concrete block 6 whose surface is covered with pebbles 31 or the like.
The lock holding unit 4 can be obtained smoothly.

Although the embodiments have been described above, the present invention includes the following aspects. In each concrete block 6, a reinforcing bar or the like as a reinforcing material is inserted. Specifically, a reinforcing bar as a reinforcing material is curved so as to protrude upward from the wire mesh 5, the lower portion thereof is held by the wire mesh 5, and the upper portion is deeply inserted into the concrete block 6. Is preferred. Thereby, the holding relationship of the concrete block 6 with respect to the wire mesh 5 is further strengthened. The frame is placed on the worktable 11, the wire mesh 5 is placed on the frame, and the space below the wire 8 area of the wire mesh 5 is made larger (deeper), and the concrete 12 that enters the space below the wire 8 is provided.
