[0009]

An embodiment of the present invention will be described below with reference to the drawings. <A> Frame for Construction of Leg Frame As shown in FIG. 1, the frame 1 is formed in a mountain shape by a member having concrete permeability, and is used for disposing a reinforcing bar 2 for reinforcing the frame. A recess 11a is formed. Here, the mountain shape is, for example, as shown in FIG. 1, a dome shape composed of both side portions 12 and an upper portion 13 continuous therewith, or a rectangular shape or a triangular shape (not shown). In other words, those that protrude upward when installed on a slope.

A member having a transparent property is used as a member for forming the frame 1. For example, nets such as wire mesh,
Perforated plates made of various materials are conceivable. In addition, the permeability of the concrete of the frame 1 is made larger at the upper portion 13 side than at the side portion 12 side of the frame body 1 so that the concrete can be easily cast from the upper portion 13 side, and at the same time, the concrete can be cast. The provided concrete is configured not to excessively flow out from the side portion 12 side.
Further, it may be formed so that the transmittance gradually increases from the lower end of the side portion 12 to the top of the upper portion 13.

FIG. 1 shows an example in which a wire mesh is used as a member for forming the frame 1. In this case, the frame 1 has a plurality of ridges 14 in a dome shape or the like arranged in parallel, and these are straightened. Multiple horizontal stripes 1
The structure integrally connected by 5 is conceivable. The mesh size is
Since it can be set arbitrarily by adjusting the interval between the chevron 14 and the horizontal streak 15, it is easy to partially change the transparency of the concrete as described above.
Note that the upper portion 13 may be configured with only the chevron-shaped streaks 14 without disposing the horizontal streaks 15.

As shown in FIG. 1, the recess 11a is formed so as to hang down from the top of the upper portion 13 of the frame body 1 and is formed at an interval where the reinforcing bar 2 for reinforcing the frame can be fitted.
The length of the recess 11a depends on the size of the cross section of one or two or three or more reinforcing bars 2 depending on the scale of the cross section of the legal frame.
Set so that it can be placed in a.

Further, as shown in FIG.
3, when provided at two places like the recesses 11b and 11c, or when provided at three or more places, and further provided, as shown in FIG. In some cases. The upper part 13 of the frame 1
Instead, any of the above concave portions may be provided in the lateral portion 12 in the lateral direction.

Although FIG. 1 shows an embodiment having no bottom surface, a bottom surface (not shown) for connecting the lower ends of both side portions 12 may be provided. Further, the bottom surface may be provided with only a predetermined width from the lower end portions of both side portions 12, and the central portion may have a shape having a slit in the longitudinal direction. The bottom forming member may be formed of the same member as the side portion 12 and the upper portion 13, or a flexible sheet member having concrete permeability may be used.

<B> Partition Member The shape of the partition member is obtained by forming the plate into a desired partition shape, and various shapes can be considered. Further, the plate constituting the partition member is made of various materials. In particular, a net having a water mesh such as a wire mesh or a perforated plate is desirable.

FIG. 6 shows two partition plates 7a and 7 such as a wire mesh.
In this embodiment, slits 71a and 71b are provided on the long side of b, and the slits 71a and 71b are engaged with each other to form a cross. Although not shown, three or more partition plates can be used to assemble into an arbitrary shape. In addition, not only a flat partition plate,
It is also possible to use a partition plate bent into an arbitrary shape.

At the end of the plate of the partition member 7, there is formed a fixing portion to be embedded in a concrete frame. The shape of the fixing portion is not particularly limited.
It is sufficient that the partition member 7 has a size and a shape that can be embedded and firmly fixed to the partition member 7. Further, it is preferable to provide a pull-out resistance member for increasing the pull-out resistance force from the legal frame concrete in the fixing portion. The pull-out resistance member may have any shape as long as the resistance can be increased, and the shape is not particularly limited.

FIG. 7 shows, as an example of a fixing portion, partition plates 7a, 7 made of a plurality of vertical stripes 72a and horizontal stripes 72b such as a wire mesh.
The shape of the fixing portion 73 at the end of b is shown. The fixing portion 73 is formed by extending each of the horizontal streaks 72b. The reason that the horizontal streak 72b is gradually shortened from the upper part to the lower part is to adapt to the connection with the dome-shaped legal frame as shown in FIG. 8, so that the length does not need to be particularly changed. Various changes are made depending on the shape of the frame.

The fixing portion 73 is provided with a plurality of pull-out resistance members 74. This pull-out resistance member 74
In this example, a rod or plate having such a size that does not hinder the joining with the concrete frame concrete is protruded in a direction intersecting the horizontal streak 72b. Further, although not shown, the pull-out resistance force can also be increased by bending the horizontal streak 72b of the fixing portion 73 itself, such as meandering. In addition,
It is also conceivable to form the fixing portion 73 composed of the horizontal streak 72b on a perforated plate other than the wire mesh.

[0020]

With reference to FIGS. 4 and 5, a method for constructing a legal frame using the frame 1 constructed as described above will be described. In addition,
In the present embodiment, the normal frame 5 is formed in a grid on the slope, but the shape of the normal frame is not particularly limited.

First, as shown in FIG. 4, the frame 1 is set on a slope. Next, the reinforcing bar 2a is fitted into the deep portion of the concave portion 11a, and the reinforcing bar 2b is further fitted into the upper portion. These rebars 2a and 2b are anchor members 3 suitably cast on slopes.
And secure it. As described above, the work of attaching the reinforcing bars 2a and 2b is very simple since it is only necessary to push the reinforcing bars 2a and 2b into the recess 11a from above.

Then, the concrete 4 is cast into the frame 1 from the upper portion 13 by spraying or the like. At this time,
The concrete 4 is cast from the frame 1 while ensuring a predetermined concrete covering thickness. After curing and hardening of the concrete 4, the legal frame 5 as shown in FIG. 5 is completed. The soil filling 6 is filled in the soil filling space 51 of the legal frame 5 to complete construction of the legal frame.

Next, with reference to FIGS. 8 and 9, a method of applying the partition member 7 configured as described above will be described.

First, as shown in FIG. 8, the frame 1 and the reinforcing bars 2a and 2b are set on the slope in the same manner as described above.

Next, as shown in FIG.
Is arranged at a predetermined partition position in the guest soil filling space 51 surrounded by the legal frame 5 (FIG. 9 shows a case where a cross-shaped partition member 7 is used). At this time, as shown in FIG. 8, the fixing portion 73 of the partition member 7 is inserted into the frame 1 and temporarily fixed with a connecting bracket or a number line. It is also conceivable that the fixing portion 73 is not inserted into the frame 1 but is positioned within the range of the thickness of the concrete and temporarily fixed so as to be self-supporting.

Then, the concrete 4 is cast into the frame 1 from the upper portion 13 by spraying or the like. At this time,
The concrete 4 is cast from the frame 1 while ensuring a predetermined concrete covering thickness. When the concrete 4 is cured and hardened, the fixing portion 73 of the partition member 7 is embedded in the concrete 4 integrally, so that the partition member 7 can be firmly fixed. Therefore, as shown in FIG. 9, the inside of the soil filling space 51 of the legal frame 5 can be partitioned. Soil filling space 5
Since the guest soil 6 filled in 1 is partitioned into a predetermined amount, there is no possibility that the soil 6 flows out due to rainwater or the like.

The above is a method of installing the partition member 7 before the concrete 4 is cast. However, the partition member 7 may be installed before the concrete 4 is hardened after the concrete 4 is cast. . In this case, the frame 1 is first assembled on the slope in the same manner as described above. After placing the concrete 4 along the frame 1, the fixing portion 73 of the partition member 7 is inserted into the concrete 4 that has not been solidified yet.

Since the concrete 4 is viscous, the partition member 7 is self-supporting without using a connection fitting or the like. In this case as well, the fixing portion 73 of the partition member 7 may be inserted into the frame 1 or may be located in the range of the thickness of the concrete. When the concrete 4 cures and hardens, the fixing portion 73 of the partition member 7 is integrally embedded in the concrete 4, so that the partition member 7 can be firmly fixed.

[0029]

Since the present invention has been described above, the following effects can be obtained. <A> Since the reinforcing bars for reinforcing the frame can be arranged in one step, the entire construction is completed in four steps, and the construction can be simplified.

<B> The reinforcing bar for reinforcing the legal frame can be arranged simply by inserting it into the concave portion of the frame, so that the mounting operation can be easily performed.

<C> Unlike the conventional structure of connecting a plurality of members using a spacer, the frame of the present invention has an integral structure that can be manufactured only by bending a single plate. The structure is simple, and the cost can be reduced.

<D> The end of the partition member is a legal frame concrete.
Since the partition member is buried in the partition, the partition member can be firmly fixed. Therefore, the outflow of the soil can be reliably prevented.

<E> The partition member is made of a simple plate,
The partition member can be fixed easily by simply burying the partition member in the legal frame concrete. Therefore, the construction can be simplified.

<F> In the method of inserting and fixing the partition member after placing the legal frame concrete, a metal fitting for connecting the partition member and the legal frame is unnecessary, so that the cost can be reduced. Can be. In addition, since the connecting work is unnecessary, it is possible to improve the construction efficiency.

<G> In the method of inserting and fixing the partition member after placing the legal frame concrete, the partition member is inserted and fixed immediately after the legal frame concrete is placed and before the partition member is installed. The inside of the box can be cleaned. Therefore, since the partition member does not become an obstacle to cleaning, cleaning can be performed easily and reliably.
