Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a unit for constructing a wall and 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 wall using 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 uniformly arranged on one side of the mesh piece on the mesh piece, Each of the concrete blocks is hardened in a state of wrapping around the location of each of the concrete blocks in the mesh pieces, and is adjacent to the concrete blocks arranged around the mesh piece in the plurality of concrete blocks. Between concrete blocks,
Passage-shaped gaps are respectively formed, and each of the gaps faces outwardly around the mesh piece on one side in the extending direction, while the other direction in the extending direction of each gap extends inside the mesh piece. The wire is set so as to be blocked by another concrete block before reaching the outside, and as the cross section of the constituent wire of the mesh is directed from the outside of the other surface of the mesh to the outside, the mesh is formed. Is set so as to be enlarged in the direction along the mesh surface of the mesh piece in a range where the constituent wire has the maximum width from the outside of the other surface,
The reinforcing member held by the net-like piece is embedded in each block, and the unit is configured as a unit for building a wall.

[0008] To achieve the first object, a second aspect is provided.
According to the invention, a plurality of concrete blocks are arranged on the one side of the reticulated piece on the reticulated piece, and each of the concrete blocks is located in the vicinity of the place where the respective one of the reticulated pieces is located. Each of the concrete blocks is hardened in a wrapped state, and nonwoven fabrics are provided on the upper surface of each of the concrete blocks as frictional force increasing means for increasing frictional force. .

In order to achieve the second object, a third aspect is provided.
According to the invention, a natural stone holding unit in which a plurality of natural stones are bonded to one surface side of the flexible sheet body is provided in a lower side area of the slope so that the plurality of natural stones are directed upward. A concrete block holding unit as a wall building unit in which a plurality of concrete blocks are held on one surface side of the net-like piece in an upper side area of the slope, and the plurality of concrete blocks are provided. A plurality of walls are laid so as to face upward, and soil covering is laid on the plurality of concrete block holding units.

[0010]

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, as the cross section of the constituent wire of the mesh piece goes from the outside on the other face side of the mesh piece to the one face side, the mesh wire is formed in a range where the component wire has the maximum width from the outside on the other face side of the mesh piece. Since it is set so as to be enlarged in the direction along the mesh surface of the piece, the physical locking relationship between the constituent wires of the mesh piece and the concrete block wrapping it is performed on a wide surface, and Even if the wrapping of the concrete block in the constituent wire is incomplete, the locking relationship is ensured. For this reason, the holding force between the mesh piece and the concrete block can be further improved. Furthermore, since the reinforcing material held by the mesh piece is buried in each concrete block, the reinforcing material and the deep inside of the concrete block have a holding relationship, and the concrete block is formed. It can be firmly held on the mesh piece.

According to the second aspect of the present invention, since the nonwoven fabric is provided on the upper surface of each concrete block as a frictional force increasing means for increasing the frictional force, not only the gap between the concrete blocks but also the nonwoven fabric is provided. , Each concrete
The upper surface of the block can also suppress the flow of soil covering and the like.

According to the third aspect of the present invention, a natural stone holding unit, in which a plurality of natural stones is bonded to one surface side of the flexible sheet member, is provided in a lower side area of the slope. A plurality of concrete block holding units as wall building units in which a plurality of concrete blocks are held on one surface side of the net-like piece in an upper side area of the slope. Since a plurality of concrete blocks are laid with the concrete block facing upward and the covering soil is piled up on the plurality of concrete block holding units, a plurality of natural stones are always provided in the lower side area of the slope where running water exists. The retaining unit fulfills functions such as revetment while maintaining harmony with nature. Normally, a plurality of concrete blocks are retained above the natural stone retaining unit where there is not much running water. While the knit functions as a substantial seawall, etc., the covering on the plurality of concrete block holding units covers the plurality of concrete block holding units to improve the appearance and return to the natural environment. Will promote. For this reason, by using the wall construction unit properly as described above, it is possible to use a concrete block which is cheaper than natural stone, and to have functions similar to those of a wall using all natural stone holding units. Thus, the cost can be reduced.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 13 show a first embodiment. 1 and 2, reference numeral 1 denotes a seawall as a wall, and in this embodiment, the seawall 1 is a seawall slope 2 as a lower area 2a, an upper area 2b, and a horizontal upper surface. And an intermediate region 2c which continuously connects 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.

As shown in FIG. 1, on the revetment slope 2
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. Each of the concrete block holding units 4 is, as shown in FIGS.
In addition, a plurality of concrete blocks 6 are disposed on the front side (one side) of the wire netting 5, and each concrete block 6 is provided.
The block 6 is hardened so as to wrap the vicinity of the concrete block 6 of the wire net 5 therein.

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 7 (in FIG. A frame 8a is provided by crossing a plurality of wires 8 inside the frame 8a.
Are formed. In the present embodiment, each wire 8 has a circular cross section as shown in FIG. 7, and the lower half of each wire 8 and the like has a width (in FIG. , The length in the left-right direction) (the corresponding portions are indicated by arrows in FIG. 7). Of course, instead of such a wire net 5, a synthetic resin net or wire is stretched horizontally within the frame 7 to form a mesh 8a or mesh, a cloth material such as a woven fabric or a non-woven fabric, or a vinyl material. A material obtained by laminating the net-like pieces on a sheet may be used.

As shown in FIG. 3, each of the concrete blocks 6 has a shape in which the upper surface 6a is narrower than the lower surface 6b, and the shape is as shown in FIGS.
For example, LD1 = 600 mm, LD2 = 350 mm, L
U1 = 500 mm, LU2 = 250 mm, LH1 = 30
0 mm and LH2 = about 20 mm. The lower portion (hardened portion) 9 of each concrete block 6 reaches the back surface (the other surface 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. As a result, each concrete block 6 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. In other words, the circular shape of the wire rod 8 in the wire mesh 5 is such that its width (length in the left-right direction in FIG. 7) gradually increases in the lower half as it goes upward, so that the outer peripheral surface of the part The concrete block 6 has a physical locking relationship with a wide locking surface. In particular, as shown by the imaginary line in FIG. 7, 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.

As shown in FIGS. 4 to 6, each concrete block 6 contains a reinforcing bar 10 as a reinforcing material. The reinforcing bar 10 is curved so as to bulge upward from the wire mesh 5, and a lower portion thereof is held by the wire mesh 5, and an upper portion thereof is deeply penetrated into the concrete block 6. Thereby, the holding relationship of the concrete block 6 with respect to the wire netting 5 is further strengthened.

The 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 in order to secure the releasability. Wire mesh 5
Is based on the fact that the diameter of the frame line 7 is larger than the diameter of the inner wire 8, and in the present embodiment, the wire 8 is knitted, so that the area of the wire 8 is slightly separated from the work surface 11 a. It is supposed to be. The wire mesh 5 holds the reinforcing bars 10 at positions corresponding to the respective concrete blocks 6 to be formed.
It protrudes upward from the wire mesh 5.

Next, a mold 13 for each concrete block 6 is placed on the wire netting 5 with one of the reinforcing bars 10 applied thereto, and shown in FIGS. As such, uncured concrete 12 is placed. Formwork 1
3 is used to form the concrete block 6 having the above-mentioned shape.
This is for applying an appropriate weight to the lower part of the door 12. As for the mold 13, in consideration of the removal of the mold 13,
A cylindrical shape that narrows upwards is used, and the internal space of the mold 13 has the same shape as that of the concrete block 6. Of course, the mold 13
May be used in which the above-mentioned molds 13 are integrated.

As a result, not only the concrete block 6 having the above-mentioned shape is formed in the mold 13 but also the uncured concrete 12 is separated from the wire mesh 5 based on its own weight.
Through the mesh 8a to the back side (the other side), and wraps around the wire mesh 5 in the area below the concrete block 6. In this case, as described above, the wire mesh 5
Since the wire 8 region is slightly separated from the work surface 11a and a space is slightly opened below the wire 8 region, the uncured concrete 12 enters the space,
The concrete 12 completely encloses the wire netting 5 part. In addition, the outer surface of the uncured concrete 12 that has entered the back side of the wire mesh 5 is formed as a flat surface by the work surface 11a.

Finally, the concrete in each mold 13
When the mold 12 is cured, each mold 13 is removed. A concrete block holding unit 4 which is held as a concrete block 6 in a fixed shape by a wire mesh 5 and is a product.
Is completed. Of course, in this case, the concrete portion 9 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.

As another mode of placing the concrete 12 in the mold 13, as shown in FIG. 11, a frame 14 is placed on the worktable 11, and the wire mesh 5 is placed on the frame 14. Good. As a result, the lower space 15 in the area of the wire 8 of the wire mesh 5 is made larger, and the concrete 12 entering the lower space 15 can completely wrap the wire mesh 5 portion.

The explanation will be returned to the revetment 1. At the time of laying, a large number of such concrete block holding units 4 are connected to adjacent concrete block 6 units via a connecting member 16 as shown in FIG. For example, as shown in FIGS. 12 and 13, a connector for connecting and disconnecting both ends of a U-shaped fitting 17 with a screw pin 18 is used as the connecting tool 16, and FIG.
As shown in the figure, in order to prevent corrosion etc.,
Or a loop 19 is used.

On the plurality of concrete block holding units 4, as shown in FIG. 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.
Is usually hard to be washed away by running 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. 15 to 18 show a second embodiment, and FIGS.
FIG. 22 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, as shown in FIGS. 15 to 18, a net-like piece has a laminated structure of a wire netting 5 and a net-like body 24 made of synthetic resin. Is held. The wrapping of the concrete block 6 into the wire netting 5 and the mesh body 24 by the concrete block 6 is increased to make the holding of the concrete block 6 stronger, and the bending of the concrete block holding unit 4 during transportation is used as a reinforcing body. The reason for this is that the wire mesh 5 is used for the suppression, and furthermore, the use of the net-like body 24 made of a synthetic resin prevents corrosion and the like after the laying, thereby providing a semi-permanent structure. In this case, the synthetic resin used for the mesh body 24 is selected from the viewpoint of preventing corrosion and the like, and the mesh 25 a is formed by the wire 25 inside the mesh body 24. Of course, a laminated structure in which the net-like body 24 is disposed below the wire net 5 may be used.

As shown in FIGS. 15 and 16, a nonwoven fabric 26 as a frictional force increasing means is attached to the upper surface of each of the concrete blocks 6. The nonwoven fabric 26 has a function of preventing the covering soil 20 from sliding down on the upper surface of each concrete block 6, whereby the holding of the covering soil 20 can be further enhanced. As another embodiment, irregularities may be formed on the upper surface of the concrete block 6.

In the concrete block holding unit 4 according to the third embodiment shown in FIGS. 19 to 22, a plurality of concrete blocks 6 are combined to form a substantially cross-shaped arrangement (see FIG. 19) or a plurality of concrete blocks 6 are arranged. 20 are combined into a substantially H-shaped arrangement (FIG. 20).
reference). When a plurality of such concrete block holding units 4 are laid on the revetment slope 2, as shown in FIG. 22, the plurality of concrete block holding units 4 are provided.
A plurality of partition spaces 27 are to be formed by the concrete block 6 in FIG.

As shown in FIG. 22, each section space 27 is to be filled with a stuffing stone 28 or the like. As the stuffing stone 28, natural stone or the like at a construction site may be used. Instead of the stuffing stone 28, a concrete waste material or the like may be used.

Then, on the stuffing stone 28 filled in each of the divided spaces 27, as shown in FIG.
0 is piled up, whereby a continuous slope of the revetment 1 is to be formed.
