(First embodiment)
With reference to FIG. 1 thru | or FIG. 5, the wooden residual formwork 100 which concerns on 1st embodiment of this invention is demonstrated.
This wooden residual formwork 100 is arranged on the front side which is the appearance side among the formwork used when concrete is cast on the front side of the slope to reinforce the slope, and remains even after the concrete is hardened. The wooden remaining mold 100 includes a first panel 10, a second panel 20, a sheet body 40, and a third panel 30.

The first panel 10 has a slat-like shape in which a plurality of (here, five) first plate members 11 extending in the horizontal direction are spaced apart in parallel.
Moreover, each 1st board | plate material 11 is the same shape altogether.
The widths of the first gaps 12 that are the gaps between the adjacent first plate members 11 are all equal.

The second panel 20 is formed by arranging a plurality of (in this case, ten) second plate members 21 extending in the vertical direction and arranged side by side in the left and right directions, and is stacked on the back side (slope side) of the first panel 10.
The width of the second plate 21 is equal to the width of the first plate 11, and the length of the second plate 21 is equal to the width of the first panel 10.
Further, the widths of the second gaps 22 that are the gaps between the adjacent second plate materials 21 are all equal, and the widths of the second gaps 22 and the first gaps 12 are also equal.

The sheet body 40 is a non-woven fabric that is difficult to permeate the ready-mixed concrete and is permeable to the noro separated from the ready-mixed concrete, and is biodegradable.
Then, the sheet body 40 is overlaid on the back side of the second panel 20.

The third panel 30 is the same as the first panel 10.
In other words, a plurality of (in this case, five) third plate members 31 extending in the lateral direction are formed in a slat-like shape and are arranged in parallel, and each third plate member 31 has the same size. Further, the widths of the third gaps 32 that are the gaps between the adjacent third plate materials 31 are all equal.
Such a third panel 30 is stacked on the back side of the sheet body 40.
Moreover, the 1st board | plate material 11, the 2nd board | plate material 21, and the 3rd board | plate material 31 use the thinning material as a raw material.

Here, the 1st panel 10, the 2nd panel 20, and the 3rd panel 30 are the substantially equal magnitude | sizes, and as shown in FIG. The nail N is struck in a state where all of the first panel 10, the second panel 20, the sheet body 40, and the third panel 30 are overlapped with each other by shifting in the vertical direction and the horizontal direction.
A location where the second panel 20 protrudes from the end portions of the first panel 10 and the third panel 30 is a convex 25, and a location where the second panel 20 is retracted from the end portions of the first panel 10 and the third panel 30. Concave 26.
In FIG. 1, the second panel 20 is shown without being shifted in order to easily understand that the first panel 10, the second panel 20, the sheet body 40, and the third panel 30 overlap. 2 and FIG. 3, the second panel 20 is shifted.

  And the location where the 1st gap | interval 12, the 2nd gap | interval 22, and the 3rd gap | interval 32 all overlap can be utilized as it is as the separator hole H which constructs the separator S (refer FIG. 2, FIG. 4).

According to the wooden residual formwork 100 configured as described above, it is difficult to permeate the raw concrete, and the noro separated from the raw concrete can be transmitted, and includes the sheet body 40 stacked on the back side of the second panel 20. Only Noro oozes out to the second panel 20 side.
And since the 2nd board | plate material 21 extended in an up-down direction is spaced apart and arranged in parallel, and the 2nd panel 20 overlapped on the back side of the 1st panel 10 is provided, as shown in FIG. It flows down the second gap 22. Therefore, it is possible to reduce the bleeding of noro to the front side of the remaining wooden form 100, that is, the front side of the first panel 10, and to prevent the front side of the remaining wooden form 100 from being stained.
As described above, since the noro flows downward through the second gap 22, the noro does not come out to the front side of the remaining wooden form 100 even if the first panel 10 has the first gap 12.
In addition, since noro flows down from the second gap 22, nose does not ooze from the joint between the remaining wooden molds 100.

Further, the heights of the first gap 12 and the third gap 32 are respectively adjusted, and the place where the first gap 12, the second gap 22, and the third gap 32 are all overlapped is defined as a separator hole H for applying the separator S. The drilling work at the site for the separator S construction is unnecessary and simple.
In addition, since the sheet body 40 is a biodegradable nonwoven fabric, when the first panel 10 and the like are biodegraded after a long period of time from construction, the sheet body 40 is similarly biodegraded and is not easily subjected to a load. .

Further, the first panel 10, the second panel 20, and the third panel 30 have substantially the same size, and the second panel 20 is shifted in the vertical direction and the horizontal direction with respect to the first panel 10 and the third panel 30. The location where the second panel 20 protrudes from the ends of the first panel 10 and the third panel 30 is a convex 25, and the location where the second panel 20 is retracted from the ends of the first panel 10 and the third panel 30. Therefore, it is easy to add the remaining wooden form 100 to the top, bottom, left and right, and the adjacent remaining wooden forms 100 are flush with each other (see FIG. 4).
In addition, as shown in FIG. 6, it is good also considering the outer surface of the thinned material as it is, and making the front side of the 1st board | plate material 11 into a curved surface.

The difference of this embodiment from the first embodiment is that the third panel 30 is not provided in this embodiment, and the other components are the same as those of the first embodiment.

Thus, even if it does not have the 3rd panel 30, since the sheet | seat body 40 suppresses the outflow of ready-mixed concrete and permeate | transmits, Noro will flow through the 2nd gap | interval 22 below.
Therefore, it is difficult for bleeding to the front side of the wooden remaining mold 100.

  In addition, even if it replaces the position of the 3rd panel 30 and the sheet | seat body 40 in 1st embodiment as shown in FIG. 8, it can suppress the bleeding to the front side of the wooden residual formwork 100 of Noro.

Further, the number and size of the first plate member 11, the second plate member 21, and the third plate member 31 in one wooden remaining mold 100 are not limited to those of the present embodiment. For example, any thickness may be made thicker than the others according to the required strength.
The first panel 10 may be configured without separating the first plate members 11 from each other. Further, the first panel 10 may have any configuration on the outer surface. For example, the outer surface of the first panel 10 may have a log tone, or may have a different thickness or a tile pattern may be formed. May be.
Furthermore, although the wooden residual formwork 100 which concerns on this embodiment has been arrange | positioned on the front side of the slope, it is not restricted to this, You may use as a formwork of the side surface used as an external appearance surface. In this case, the wooden remaining mold 100 is formed in a trapezoidal shape.

Further, the joining method of the first panel 10, the second panel 20, and the third panel 30 is not limited to the nail N.
Moreover, the convex solid 25 and the concave solid 26 do not need to be formed in the wooden residual formwork 100.

Further, the sheet body 40 is not limited to a non-woven fabric, and may be a cloth body that mainly transmits only a slot.
Although the first panel 10, the second panel 20, and the third panel 30 are made of thinned wood, the present invention is not limited to this, and some or all of the wood may be other woody materials such as laminated plywood. . Furthermore, it may be made of metal such as steel.
