A preferred aspect of the fifth aspect is as described in the sixth aspect.

[0008]

According to the first aspect of the present invention, a wooden frame in which a flexible sheet frame is built along the inner surface and a plurality of stones are held on one side of the plate body. Prepare a stone holding unit to do, then fill the flexible sheet mold with concrete, then in the concrete,
In the uncured state of the concrete, since the plate-like body of the stone holding unit is embedded below the plurality of stones of the stone holding unit, the concrete pedestal is placed in the wooden frame of the cross beam by the method. Is housed so that the periphery of the pedestal is surrounded, a flexible sheet frame is interposed between the wooden frame and the pedestal, and a plurality of stones are provided on the pedestal. This makes it possible to specifically manufacture a civil engineering block in which a stone is held by a plate-like body embedded in the pedestal. Further, since the wooden frame or the like is used as it is without being demolded, unlike the usual case where the use and demolding of the frame are performed, the number of the frame is not limited, and the sequential It will be possible to manufacture blocks for civil engineering. Furthermore, since the wooden frame is used as a formwork,
Unlike a normal steel form, the size can be easily adjusted, and the weight of the civil engineering block can be easily adjusted.

In this case, in the civil engineering block manufactured by the invention according to claim 1, the following operational effects are produced.

By using the civil engineering block on a construction surface, a pedestal that covers the construction surface and a plurality of stones on the pedestal can substantially exert a revetment, revetment, and wave-dissipating function. Meanwhile, the civil engineering block,
In the upper part of the pedestal, the concrete (after hardening) that constitutes the pedestal and the plate-like body as the embedding material are physically engaged with each other, so that a plurality of stones are held on the pedestal. It is possible to easily hold a plurality of stones on the pedestal by utilizing the characteristics of (the uncured state and the curing stage). Therefore, the civil engineering block can be easily and promptly manufactured while ensuring high reliability regarding strength. Also, since wood is arranged at least around the pedestal, in the use stage after completion,
With the wood, the civil engineering block can be blended into the surrounding natural scenery without any discomfort, and the natural trees that make up the wood can be contributed as nutrient sources such as seaweed, creating a rich sea. It will be possible. Of course, in the civil engineering block, the concrete pedestal occupies most of the civil engineering block and shows the character as a heavy object, and the same weight stability as before is ensured. The stones are in harmony with the surrounding natural landscape, and the voids in each stone secure a habitat for insects, fish, shellfish, etc.

Further, since the wood constitutes a wooden frame for accommodating the pedestal, the structure allows not only the wooden frame to be used as a mold to produce the pedestal, but also the wooden frame as the mold. It is possible to save the labor of demolding while keeping the wooden frame as a means to harmonize with the surrounding environment. Furthermore, structurally, after using the wooden frame as a formwork,
Since it can be used as it is without demolding, unlike the usual case where the use and demolding of the formwork is performed, it is possible to smoothly and sequentially manufacture the civil engineering block without being limited by the number of formwork. Become. Furthermore, because of its structure, the wooden frame can be used as a mold, which makes it possible to easily adjust the size, unlike a normal steel mold, and to easily adjust the weight of the civil engineering block. You can do it.

Further, since the flexible sheet mold is interposed between the wooden frame and the pedestal, not only the wooden frame but also the flexible sheet mold is used as the frame to mount the pedestal. It will be possible to form reliably. Of course, even if the flexible sheet formwork disappears due to long-term use after the start of use, it does not affect the revetment, the seawall, and the wave-dissipating function.

Further, since the wooden frame is formed in a cross beam shape, the habitat space for fish and the like can be accurately secured by the gap based on the cross beam shape of the wooden frame. On the other hand, even if this wooden frame is in the shape of a cross girder, since the flexible sheet mold is built in the interior, the flexible sheet mold will receive concrete and ensure the pedestal. Will be able to be formed.

Further, since the embedding material is a plate-shaped body and a plurality of stones are attached to one surface side of the plate-shaped body, the engagement relationship (area) between the hardened concrete forming the pedestal and the embedding material. Therefore, the holding strength of a plurality of stones on the pedestal can be remarkably increased as compared with the case where an embedding material is attached to each stone. Moreover, at the manufacturing stage, it is possible to carry all of the plurality of stones with the plate-like body and put it in the uncured concrete that will form the pedestal, and the embedding material will be attached to each stone. It is possible to reduce the manufacturing (work) burden compared to the case where there is.

According to the second aspect of the present invention, there are provided a cross-shaped wooden frame in which a flexible sheet frame is installed along the inner surface, and a plurality of stones with anchors to which anchors are attached. , Prepare, and then fill the flexible sheet formwork with concrete, then, in the concrete, in the uncured state of the concrete, the anchor of the stone with anchor, than the stone of the stone with anchor Since it is also embedded on the lower side, by this method, a concrete pedestal is housed in a double girder-shaped wooden frame so that the periphery of the pedestal is surrounded, and flexible between the wooden frame and the pedestal. It is possible to specifically manufacture a civil engineering block in which a mold made of a flexible sheet is interposed, a plurality of stones are provided on the pedestal, and the stones are attached to anchors embedded in the pedestal, respectively. . Also in this case, as in the case of claim 1,
The civil engineering blocks can be manufactured smoothly and sequentially without being restricted by the number of molds, and the size of the civil engineering blocks can be easily adjusted by using the wooden frame to easily adjust the weight of the civil engineering blocks. You can do it.

In this case, in the civil engineering block manufactured by the invention according to claim 2, the same operation as that of the invention according to claim 1 is performed except for the peculiar effect based on the anchoring of the embedding material. On the other hand, while the effect is produced, since the embedding material serves as an anchor, each stone can be easily and accurately fixed to the pedestal by using the anchor. Moreover, based on the structure of the civil engineering block, the anchors of the stones with anchors can be individually embedded in the manufacturing stage, and the placement position of each stone with respect to the upper surface of the pedestal can be determined with a high degree of freedom.

According to the third aspect of the invention, since the wooden frame is fixed on the bottom plate before the flexible sheet formwork is filled with concrete, the concrete injection can be reliably received by the bottom plate. In addition, it is possible to manufacture the civil engineering block with the bottom plate preliminarily floated, and facilitate the transportation work (roping, lifting work, etc.) of the civil engineering block after the manufacturing.

In this case, in the civil engineering block manufactured by the invention according to claim 3, the wooden frame is fixed on the bottom plate, and the pedestal is stored in the wooden frame on the bottom plate. Not only the friction and engagement between the wooden frame and the wooden frame but also the weight of the pedestal as a heavy object can be used to prevent the wooden frame from coming off the pedestal through the bottom plate.

According to the invention of claim 4, before the concrete is filled in the flexible sheet mold, the connecting member is provided between the gaps of the cross-shaped wooden frame and the flexible sheet mold. Since it is in a state of being penetrated and entered into the flexible sheet mold, the gap of the wooden frame can be used as a through hole of the connecting member, and the upper and lower section screens of the gap can be used as engaging surfaces. Therefore, when the wooden frame and the pedestal are integrated, the gap between the wooden frames can be effectively used.

According to the fifth aspect of the present invention, there is prepared a cross-shaped wooden frame in which the flexible sheet mold is installed along the inner surface thereof, and then the flexible sheet mold is placed in the flexible sheet mold. By filling with concrete, by this method, a concrete pedestal is housed in a double-sided wooden frame so that the periphery of the pedestal is surrounded, and a flexible sheet is provided between the wooden frame and the pedestal. It is possible to specifically manufacture the civil engineering block in which the molding frame is interposed. Further, before the concrete is filled in the flexible sheet mold, the connecting member is penetrated through the gaps in the cross-shaped wooden frame and the flexible sheet mold to make the flexible sheet mold. Since it is in the state of having entered inside,
The gap of the wooden frame can be used as a through hole of the connecting member, and the upper and lower section screens of the gap can be used as an engaging surface, so that the gap of the wooden frame can be effectively used when the wooden frame and the pedestal are integrated. become.

In this case, the civil engineering block manufactured by the invention according to claim 5 can be structurally simply manufactured as in the case of the invention according to claim 1, while the concrete pedestal enables weight stability. , It is possible to secure the sea wall, the sea floor function, etc., and the wooden frame makes it possible to achieve harmony with the surrounding natural environment.

According to the sixth aspect of the present invention, a substantially U-shaped connecting member is used, and both ends of the connecting member are formed into upper and lower divided screens which define the gaps between the wooden frames on both sides of the connecting member. Since the flexible sheet is made to enter into the flexible sheet frame while being engaged in a biased state, before the concrete is filled before forming the pedestal, the spring property based on the substantially U-shape of the connection member (expansion and contraction property on both sides of the connection member). ) Can be temporarily held in the wooden frame, and after the concrete is filled, the expansion and contraction of the connecting member can be lost by hardening the concrete and the pedestal and the wooden frame can be integrated.

According to the invention of claim 7, while maintaining the effect of each claim, the manufactured civil engineering block can be properly made to function as a floor protection or root consolidation.

According to the invention of claim 8, while maintaining the operation and effect in each claim, the manufactured civil engineering block can properly function as a revetment.

According to the invention of claim 9, while maintaining the effect of each claim, the manufactured civil engineering block can properly function also as a wave canceller.

In this gently sloping proposal 1, a large number of the civil engineering blocks 4 according to the first embodiment have a revetment function and a wave-dissipating function on the construction surface 2 (slope, slope, shoulder) via the backfill layer 3. Has been laid to ensure.

The back-filling layer 3 is formed along the construction surface 2,
It is formed by pebbles, crushed stones, etc. to have a certain thickness. Based on this backfill layer 3, the ground bearing capacity and bearing capacity are strengthened, and the permeated water from the surface slope and the leached water from the slag body ( It is supposed to secure the effect as a filter against sand particles and to reduce the return wave (return flow) to reduce scour.

As shown in FIGS. 1 to 4, the civil engineering block 4 includes a wooden frame (wood) 5, a concrete pedestal 6 provided in the wooden frame 5, and a plurality of pedestals provided on the upper surface of the pedestal 6. It is roughly composed of natural stones 7 and.

The wooden frame 5 is, as shown in FIGS. 3 and 4,
The machined logs 8 made of square wood are assembled alternately and formed in a cross beam shape, and the machined logs 8 at the respective intersections at the four corners are connected by penetrating a long bolt and screwing nuts thereto. . As a result, the wooden frame 5
A quadrangular shape when viewed from above (in this embodiment, one side is 200
While defining an internal space 9 of about 0 mm square),
A gap 10 for communicating the internal space 9 with the outside is to be formed in a portion of the stacked steps of the processed logs 8 which does not exist. In addition, in FIG. 2 and FIG. 3, a series of fasteners constituted by the long bolts, nuts and the like are indicated by reference numeral 11.

As shown in FIGS. 3 and 4, a cloth mold 12 as a flexible sheet mold is built in the wooden frame 5. The cloth frame 12 is made of cloth such as chemical fiber,
It is formed in a bag shape, and the side surface of the cloth mold 12 is accommodated along the inner surface of the wooden frame 5, and the upper opening thereof constitutes the wooden frame 5 with the fastener 13 having a substantially U-shaped cross section. It is fastened to a processed log 8. In addition, in FIG. 3, in order to make the wooden frame 5 easy to see, a cross section of the cloth frame 12 is taken,
Illustration of the fastener 13 is omitted.

The pedestal 6 is, as shown in FIGS. 3 and 4,
It is housed in the cloth mold 12 inside the wooden frame 5 and occupies the entire inner volume of the wooden frame 5. The side surface 6a of the pedestal 6 swells to some extent at a position where a gap 10 between the wooden frame 5 (between the upper and lower processed logs) exists, and the bulge portion 1
6 enters the gap 10 together with the cloth frame 12, and the side surface 6a of the pedestal 6 and the wooden frame 5 are engaged with each other to prevent the wooden frame 5 from coming off the pedestal 6 reliably. On the other hand, the upper surface 6b and the lower surface 6c of the pedestal 6 form flat surfaces.

As shown in FIGS. 1 to 4, the plurality of natural stones 7 are fixed on the entire top surface 6b of the pedestal.
Each natural stone 7 has a diameter of about 300 to 500 mm (preferably 400 mm).
Is firmly attached to the wire net 17 corresponding to the pedestal upper surface 6b (square in plan view) on one side through the mounting washer 18 and the driving anchor 19, and the wire net 17 and its The lower part of each natural stone 7 (1 / of the whole
3 or less) is embedded in the concrete pedestal 6. As a result, the concrete forming the pedestal 6 wraps the constituent wire rods of the wire net 17 and the concrete wire forming the pedestal 6 and the constituent wire rods of the wire net 17 are engaged with each other. Even if 2/3 or more of the natural stones 7 and the pedestal 6 are projected upward from the pedestal upper surface 6b, the natural stones 7 and the pedestal 6 are firmly integrated. In this case, as the wire net 17, various things such as a rhombic wire net and a hexagonal wire net can be used. However, instead of the wire net 17, a synthetic resin net, a carbon fiber net, a mesh, various rebars, a steel frame (rebar-shaped rebar, Lattice-shaped reinforcing bars, etc.) may be used as appropriate.

In this embodiment, as shown in FIG. 4, legs 31 are provided at the lower portions of the four corners of the wooden frame 5, respectively. Each of the legs 31 is formed of a short square bar (for example, a square end face having a side of about 125 mm and a length in the extending direction of about 400 mm) (FIG. 4 shows the end face). The portion 31 is fixed to the lower portions of the four corners of the wooden frame 5 by using the fastener 11 so that the wooden frame 5, the pedestal 6 and the like are floated from the backfill layer 3. This is taken into consideration when the flat lower surface of the pedestal 6 is placed on the uneven backfill layer 3 as it is, so that the installation stability may be deteriorated (unstable), and this is solved. Therefore, the four legs 31 support the wooden frame 5, the pedestal 6 and the like at four points.

The civil engineering block 4 as described above is manufactured as follows. First, the cross-shaped wooden frame 5 (see FIG. 5) having the cloth mold 12 built therein and a natural stone holding unit 20 (see FIG. 6) holding a plurality of natural stones 7 are prepared. The cloth frame 12 is built in the wooden frame 5, and the upper opening of the cloth frame 12 is the fastener 1.
It is fastened to the wooden frame 5 with 3.

On the other hand, the natural stone holding unit 20 has a base 6
The plurality of natural stones 7 are evenly arranged on one surface side of the square-shaped wire net 17 corresponding to the upper surface 6b of each of the natural stones 7.
It is fixed to the wire net 17 using a mounting washer 18 and a driving anchor 19. In manufacturing the natural stone holding unit 20, a plurality of natural stones 7 having mounting holes (not shown) are prepared, and the plurality of natural stones 7 are arranged on the work surface with the mounting holes facing upward. Wire net 17 on natural stone 7
Cover. Then, the mounting washer 18 is directed onto the metal net 17 for each natural stone 7, and the insertion hole (not shown) of the mounting washer 18,
The anchor 19 is inserted through the mesh of the wire net 17 and the natural stone 7
The natural stones 7 and the wire nets 17 are integrated by driving them into the mounting holes. Of course, in this case, the driving anchor 19
Instead of the above, the natural stone 7 and the wire net 17 may be integrated by using an adhesive.

Next, as shown in FIG. 5, while placing the wooden frame 5 on the work soil surface, each leg portion 31 is buried in the work soil (preferably sandy soil). This is because when the concrete is filled in the next step, the working soil surface is properly used as the concrete receiving surface without being hindered by the support structure based on the leg portions 31.

Next, in order to form the pedestal 6, as shown in FIG. 6, the cloth mold frame 12 in the wooden frame 5 is filled with concrete. In this case, from the viewpoint of securing the weight as much as possible, it is preferable to inject concrete so that bubbles are not formed inside as much as possible. Moreover, when pouring this concrete, a waste material such as steel slag may be added as a filling material. This allows waste to be sequestered and reduces the heavy weight of the waste.
It can be used as the weight of the pedestal 6. Of course, in this case, it is also possible to add iron, silica, etc., which are deficient in seawater.

Next, in order to integrate the concrete in the wooden frame 5 and the natural stone holding unit 15, as shown in FIG. 6, before the concrete in the cloth frame 12 is cured, The natural stone holding unit 20 is inserted from the upper opening. At this time, the natural stone holding unit 20 is submerged in the uncured concrete while setting the wire net 17 below the plurality of natural stones 7 and the lower part of the wire net 17 and each natural stone 7 (1/3 or less of the whole). Are embedded in the uncured concrete, and 2/3 or more of each natural stone 7 is projected upward from the uncured concrete upper surface 6b. In this case, from the viewpoint of improving workability, the wire mesh 17
In consideration of the buoyancy of uncured concrete that acts on a plurality of natural stones 7 (including the buoyancy associated with changes over time (change in hardening degree)), the natural stone holding unit 20 is placed on the uncured concrete upper surface 6b in the formwork 13. It is preferable to set the natural stone holding unit 20 so that the natural stone holding unit 20 sinks only by the desired depth in view of the balance with the weight of the natural stone holding unit 20 just by placing it. Of course, considering the intensity of the waves,
The deeper the submerged amount of the natural stone holding unit 20 (the wire net 17), the deeper the submerged amount of the natural stone holding unit 20 (the wire net 17) becomes, so that the hardened concrete is held (engaged) with respect to the wire net 17 at the time of use. It is better to raise.

After that, the hardening of the uncured concrete in the wooden frame 5 is waited, and the production is finished.

As described above, the civil engineering block 4 has a physical engagement relationship between the concrete pedestal 6 and the wire net 17 (a relationship in which hardened concrete wraps the wire rods constituting the wire net 17).
Therefore, since the plurality of natural stones 7 (natural stone holding units 15) are held on the pedestal 6, it is possible to firmly hold the plurality of natural stones 7 (natural stone holding unit 15) on the pedestal 6. Instead, it is possible to easily and quickly obtain the strong holding of the concrete by utilizing the characteristics of the concrete (uncured state, hardening stage) at the time of production. In addition, it is possible to save the work of demolding while leaving the wooden frame 5 as a mold and making the most of the wooden frame 5 as a means to harmonize with the surrounding environment.

When constructing the gently sloping stud 1, a large number of such civil engineering blocks 4 are arranged on the back-filling layer 3 in an appropriate positional relationship, as shown in FIG.
Pacing stones 22 are filled in the gaps 21 between the respective civil engineering blocks 4. In this case, it is preferable that the adjacent civil engineering work blocks 4 are connected to each other by using a connecting tool, and the upper part of the cloth form frame 12 is removed so that the wooden frame 5 is exposed. Is preferred.

Therefore, in such a gently inclined sill 1, the construction surface 2 has the pedestal 6, the natural stone 7 on the pedestal 6, and in the present embodiment, the filling stone 2 filled in the cavity 21.
2 will also be covered by the pedestal 6, the natural stones 7 on the pedestal 6, the roughness of the filling stones 22 and the like, a revetment function (including revetment, root consolidation, etc.) The beach scour prevention effect will be demonstrated.

On the other hand, each of the civil engineering blocks 4 has a property of being a heavy object based on the concrete pedestal 6 and a preferable mode of connecting the civil engineering blocks 4 to each other, whereby the position retaining property of each of the civil engineering blocks 4 is maintained. (Weight stability) will be enhanced. Moreover, regarding the filling stones 22, the construction (the staggered arrangement) in which the neighboring civil engineering blocks 4 face each other between the civil engineering blocks 4 in each row means that the filling stones 2 are washed away (washed away). ) Will be suppressed. Therefore, this gentle slope 1
In the above, it is possible to surely exert the revetment and wave-dissipating functions also by the filling stones 22.

Naturally, the natural stones 7 on the pedestal 6 and the filling stones 22 filled in the voids 21 are in harmony with the surrounding natural landscape, and the voids of the natural stones 7 etc. are insects, fish and shellfish. It also serves as a habitat for people such as.

In each of the embodiments, the same components as those in the above embodiment are designated by the same reference numerals, and the description thereof will be omitted.

In the second embodiment shown in FIG. 7, the natural stone holding unit 20 according to the above embodiment is used as an embedding material.
Instead of, the anchor 23 is used for each natural stone 7. The anchor 23 has one end fixed to the natural stone 7 and the other end bent to ensure resistance to the hardened concrete. As a result, the natural stones 7 can be easily and accurately attached to the pedestal 6 with the anchors 23, and the anchors 23 of natural stones with anchors can be individually embedded when the concrete is not cured,
The arrangement position of each natural stone 7 with respect to the upper surface of the pedestal 6 can be freely determined. Of course, also in this case, the leg portions 31 according to the first embodiment may be provided at the lower portions of the four corners of the wooden frame 5 to form a four-point support structure.

The third embodiment shown in FIG. 8 shows a modification of the arrangement of the civil engineering block 4 according to the first embodiment. In the third embodiment, as shown in FIG. 8, the civil engineering blocks 4 are arranged in order so as to form a continuous row in the vertical and horizontal directions.
Pacing stones 22 are filled between them. As a result, the revetment function and the like can be exerted even in this arrangement structure.

The fourth embodiment shown in FIGS. 9 to 11 shows a civil engineering block suitable not only for the wave-dissipating function but also for the protection of floor and the consolidation of roots. In this civil engineering block 4, a wooden frame (a wooden frame part or a basic wooden frame part) 40 and a wooden frame (a wooden frame part or a stacked wooden frame) 41 are stacked in a plurality of stages (two stages in this embodiment). Thus, the pedestal 6 is housed in the wooden frame 40 in the lower stage, and the filling stones 42 are filled from above the pedestal 6 in the wooden frame 40 to the wooden frame 41 in the upper stage.

That is, in the lower wooden frame 40, as in the first and second embodiments, as shown in FIG. 11, a cloth mold (for example, a non-woven mold) 12 made into a box shape by folding.
(In the present embodiment, a plurality of U-shaped fasteners are fixed at a plurality of positions by driving it into the inner surface of the wooden frame via the cloth mold 12), and the concrete inside the cloth mold 12 is After being injected, the pedestal 6 is housed and held in the wooden frame 40 as in the above embodiment.

On the other hand, the upper wooden crate 41 does not have the cloth mold 12 built therein, and the upper wooden crate 41 is connected to the lower wooden crate 40 in a stacked state. In this connection, as the connecting tool, the first
A series of fasteners 11 according to the embodiment are used as common ones, and long bolts of the fasteners 11 penetrate through four corners of upper and lower wooden frames 40 and 41, and upper and lower ends thereof are nuts. It is to be tightened. Of course, as another connecting method, the wooden frame 40 in the lower stage is connected to the series of fasteners 1
After assembling with No. 1, another connecting tool such as a wire may be used to connect the upper wooden frame 41 to the lower wooden frame. Inside the upper wooden crate 41 and the lower wooden crate 40 (in the lower wooden crate 40, the space above the pedestal 6) are filled with the filling stone 42.
Are engaged with each other and also with the wooden frame 41, and are integrated with the wooden frame 41.

Such a civil engineering block 4 is disposed on the construction surface 2 as shown in FIGS. 2 and 8, for example, and is used not only as a revetment and wave-dissipating block, but also as a revetment and rooting block. Will be used as. Of course, also in this case, the leg portions 31 according to the first embodiment may be provided at the lower portions of the four corners of the wooden frame 40 to form a four-point support structure.
