[0004] [Patent Document 1] Registered Utility Model No. 3190102 Summary of the Invention [Problem to be solved by the invention]

[0005] FIG. 12 is a side view of a wooden fence 1 made up of the wooden fence panels 10 described in Patent Document 1, installed as an earth retaining wall, and corresponds to FIG. 3 in Patent Document 1. The wooden fence 1 is erected from the ground surface GL and comprises posts 2 arranged at predetermined intervals, and a plurality of wooden fence panels 10 fixed to the posts 2 and arranged adjacent to each other in the left-right direction. In addition, the wooden fence 1 may have soil B piled up on the rear side, and may be installed in multiple steps on a slope as shown in FIG. 12, depending on the inclination angle and height of the slope on which it is installed.

[0006] In Fig. 12, if the soil B piled up on the rear side of the wooden fence 1 is clayey, the soil B will have poor drainage and a lot of water will remain. If this condition continues for a long time, the planted trees T may suffer from root rot and die. Therefore, it is necessary to improve the drainage capacity of the soil B.

[0007] To provide a wooden fence panel for improving the drainage capacity of soil piled up on the rear side of a wooden fence, and also to provide a wooden fence panel that reduces the number of processes at the work site and the number of rework processes, thereby improving the construction efficiency of the wooden fence. [Means for solving the problem]

[0008] (1) A wooden fence panel that is erected from the ground surface, fixed to posts arranged at a predetermined interval, and formed by stacking rectangular boards with the same width as the predetermined interval in the vertical direction, A wooden fence panel in which the boards stacked on top of one another are positioned so that their side edges in the direction of the arrangement of the posts protrude a predetermined distance from the side edges of the boards in the direction of the arrangement, and drainage holes are drilled at predetermined positions in the boards, and the drainage holes are covered with filters.

[0009] According to the configuration (1), the wooden fence panel is erected from the ground surface and fixed to posts arranged at a predetermined interval. The wooden fence panel is formed by stacking rectangular boards with a width dimension equal to the predetermined interval in the vertical direction. This means that, for example, wooden fence panels can be manufactured in a factory by stacking boards vertically, transported to a work site, and fixed to posts, thereby improving the efficiency of wooden fence construction compared to attaching boards to posts one by one at a work site with poor footing.

[0010] Furthermore, a plate material that is stacked on top of another plate material is positioned such that its side edge in the arrangement direction of the posts protrudes a predetermined distance in the arrangement direction from the side edge of the other plate material. This allows the width of the wooden fence panel to be the specified distance plus the specified dimension. Therefore, for example, even if the spacing between the posts becomes wider than the specified distance, as long as the spacing between the posts is within the range of the specified distance plus the specified dimension, there is no need to make any adjustments to the position of the posts. This makes it possible to provide a wooden fence panel that reduces the number of processes at the work site and the need for rework, thereby improving the efficiency of wooden fence construction. In addition, drainage holes are drilled at predetermined positions in the boards that make up the wooden fence panel, and the drainage holes are covered with filters. This allows moisture in the soil on the rear side of the wooden fence to be drained through the drainage holes, and the filter prevents the drainage holes from becoming clogged with clay, gravel, etc. in the soil, improving the drainage capacity.

[0011] (2) The plate material has upper and lower side edges, which are arranged on the upper and lower sides, formed with horizontal engagement portions extending in the arrangement direction of the support columns, A wooden fence panel as described in (1), in which the lateral engagement portions of the upper and lower side edges of one of the boards and the lateral engagement portions of the lower and upper side edges of the board placed on top of another of the boards engage with each other.

[0012] According to the configuration of (2), the plate material has a lateral engagement portion formed on the upper or lower side edge located on the upper or lower side, the lateral engagement portion extending in the arrangement direction of the support posts. The lateral engagement portions on the upper and lower side edges of a plate material and the lateral engagement portions on the lower and upper side edges of a plate material placed on top of the plate material engage with each other.

[0013] This means that one board material can be connected to another board material, and one wooden fence panel can be connected to an adjacent wooden fence panel, simply by engaging one lateral engagement portion with the other lateral engagement portion, without the need to attach metal fittings or the like to connect them to each other. This improves efficiency in the manufacture of wooden fence panels and the construction of wooden fences.

[0014] (3) Of the lateral engagement portions of the upper and lower side edges, One of the lateral engagement portions is a groove extending in the arrangement direction of the columns, The other horizontal engagement portion is a protrusion extending in the arrangement direction of the posts and fitting into the groove. Wooden fence panel described in (2).

[0015] According to the configuration of (3), one of the lateral engagement parts at the upper or lower side edge is a groove extending in the arrangement direction of the columns, and the other lateral engagement part is a protrusion extending in the arrangement direction of the columns and engaging with the groove.

[0016] Such wooden fence panels are formed in a factory by placing one board on top of another and fitting protrusions formed on the upper and lower edges of the upper side of one board into grooves formed on the lower upper and lower edges of the other board. The wooden fence panels manufactured in this manner at the factory are then transported to the wooden fence construction site, where, for example, one wooden fence panel is placed to the right of another wooden fence panel, and a protrusion formed on the upper edge of the left side edge of one wooden fence panel is fitted into a groove formed on the lower edge of the right side edge of the other wooden fence panel.

[0017] In this way, one board and another board, and one wooden fence panel and another wooden fence panel, can be connected to each other simply by fitting the protrusion of one into the groove of the other, without the need for attaching metal fittings or the like to connect them to each other. This improves efficiency in the manufacture of wooden fence panels and the construction of wooden fences. Effect of the Invention

[0018] According to this invention, it is possible to provide a wooden fence panel that can improve the drainage capacity of moisture in the soil piled up on the rear side of a wooden fence, reduce the number of processes at the work site, eliminate the need for rework, and improve the construction efficiency of the wooden fence.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] The configuration of a wooden fence panel 10 according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a wooden fence 1 to which a wooden fence panel 10 according to one embodiment of the present invention is applied. FIG. 2 is a diagram showing a wooden fence 1 to which the wooden fence panel 10 according to the embodiment is applied, viewed from above. FIG. 3 is a side view of a wooden fence 1 to which the wooden fence panel 10 according to the embodiment is applied, installed as an earth retaining wall. The wooden fence 1 is erected from the ground surface GL and, as shown in Figure 1 or Figure 2, comprises posts 2 arranged at a predetermined interval W, and a plurality of wooden fence panels 10 fixed to the posts 2 and arranged consecutively in the left-right direction. In addition, the wooden fence 1 may be piled up on its rear side and installed in multiple steps on a slope, as shown in FIG. 3, depending on the inclination angle and height of the slope on which it is installed.

[0021] FIG. 4 is a front view of the wooden fence panel 10 according to the embodiment. FIG. 5 is a view of the wooden fence panel 10 according to the embodiment as viewed from above. FIG. 6 is a rear view of the wooden fence panel 10 according to the embodiment. FIG. 7 is a view of the wooden fence panel 10 according to the embodiment as viewed from below. FIG. 8 is a side view of the wooden fence panel 10 according to the embodiment. The wooden fence panel 10 is formed by stacking vertically rectangular board materials 11 with a width dimension W that is the same as the predetermined distance between the posts 2 (see FIG. 1). In this embodiment, the wooden fence panel 10 is formed by stacking four board materials 11, but this is not limited to this, and any number of board materials 11 can be stacked depending on the size of the wooden fence panel 10 and the size of the board materials 11.

[0022] Moreover, the plate material 11 stacked on top of another plate material 11 is arranged in such a position that the side edge in the left-right direction, which is the arrangement direction of the posts 2, protrudes a predetermined distance S in the left-right direction from the side edge of the other plate material 11. As a result, the wooden fence panel 10 in this embodiment is formed by stacking four boards 11, and its width dimension is formed by adding up the width dimension W of the board 11 and the three specified dimensions S.

[0023] Drainage holes H are formed at predetermined positions of the plate materials 11. As shown in Figures 1, 4, 6 and 8, in this embodiment, of the four plate materials 11, the second plate material 11 from the bottom and the third plate material 11 from the bottom are formed with circular drainage holes H, and the bottommost and topmost plate materials 11 are not formed with drainage holes H, but the bottommost and topmost plate materials 11 may also have drainage holes H formed therein if necessary.

[0024] For ease of explanation, the second plate 11 from the bottom in which drainage holes H are formed is referred to as plate 11L, and the third plate 11 from the bottom is referred to as plate 11U. Two drainage holes H are formed in each of plate 11L and plate 11U. The drainage holes H of plate 11L and plate 11U are positioned so that they do not overlap vertically.

[0025] As shown in Fig. 6, the two drainage holes H of the plate material 11L are disposed between the right anti-slip groove 103a and the central anti-slip groove 103a, and between the central anti-slip groove 103a and the left anti-slip groove 103a. The two drainage holes H of the plate material 11U are disposed between the right anti-slip groove 103a and the central anti-slip groove 103a, and between the central anti-slip groove 103a and the left anti-slip groove 103a. In Fig. 6, the four drainage holes H are disposed so as to be spaced apart at approximately equal distances.

[0026] By forming the drainage holes H as described above, moisture contained in the soil B on the rear side of the wooden fence 1 can be drained through the drainage holes H to the front side of the wooden fence 1, as shown in Figure 3, for example.

[0027] Here, there is a possibility that the drainage holes H will be clogged by clay, gravel, etc. in the soil B, causing the drainage function to deteriorate or stop. To address this issue, in this embodiment, the drainage holes H are covered with filters F. For example, CureMat (registered trademark) is used as the filter F. As shown in FIG. 6, the filter F is formed in a rectangular shape, and is fitted over the drainage holes H from the rear side of the plate materials 11L and 11U. The shape of the drainage holes does not have to be limited to a circle, and the shape of the filter F does not have to be limited to a rectangle.

[0028] By covering the drain hole H with the filter F in this manner, clogging of the drain hole H can be prevented, and the drainage capacity of the drain hole H can be improved.

[0029] Fig. 9 is a side view of two plate materials 11 according to the embodiment. Note that drainage holes H and filters F are not shown in Figs. When the wooden fence 1 (see Figure 1) is installed, the board 11 has upper and lower side edges which engage with each other and are located on the upper or lower side, and have lateral engagement portions 110 which extend in the arrangement direction of the posts 2 (see Figure 1). The lateral engagement portions 110 on the upper and lower side edges of a certain plate material 11 and the lateral engagement portions 110 on the lower upper and lower side edges of a plate material 11 disposed above the certain plate material 11 engage with each other.

[0030] The plate material 11 also has, as upper and lower side edges, a lower edge 111 disposed on the lower side and an upper edge 112 disposed on the upper side. The lower edge 111 is formed with a groove 111a as a horizontal engagement portion 110, the groove 111a extending in the arrangement direction (left-right direction in FIG. 1) of the posts 2 (see FIG. 1). The upper edge 112 is formed with a protrusion 112a as a lateral engagement portion 110, which extends in the arrangement direction (left-right direction in FIG. 1) of the posts 2 (see FIG. 1) and fits into the groove 111a. In this embodiment, groove 111a is formed on lower edge 111 and protrusion 112a is formed on upper edge 112, but this is not limited to the above, and a protrusion may be formed on lower edge 111 and a groove may be formed on upper edge 112.

[0031] 8, in this embodiment, the upper edge 112 of the board 11 arranged in the uppermost row has no protrusion. Also, the lower edge 111 of the board 11 arranged in the lowermost row has no groove. As a result, when viewed from the front, the vertical widths of the multiple boards 11 in the wooden fence panel 10 are aligned, improving the design.

[0032] FIG. 10 is a side view of a plate material 11A according to a modified example of the embodiment. The plate material 11A differs from the plate material 11 according to the embodiment shown in FIG. 9 in the shape of the lateral engagement portion. The plate material 11A has a lower edge 111, on the front side, formed with a front notch 111b as a lateral engagement portion 110A, the front notch 111b extending in the arrangement direction (left-right direction in FIG. 1) of the posts 2 (see FIG. 1). Furthermore, the plate material 11A has, on the upper edge 112, a rear notch 112b formed as a lateral engagement portion 110A on the rear side, which extends in the arrangement direction (left-right direction in FIG. 1) of the posts 2 (see FIG. 1) and engages with the front notch 111b. In this modified example, a front notch 111b is formed on the lower edge 111 and a rear notch 112b is formed on the upper edge 112, but this is not limited to the above, and a rear notch may be formed on the lower edge 111 and a front notch may be formed on the upper edge 112.

[0033] As shown in Figure 6, the wooden fence panel 10 has a rear surface 103 formed with a plurality of anti-slip grooves 103a at predetermined intervals that extend in the vertical direction and span the multiple boards 11 that make up the wooden fence panel 10. A displacement prevention member 13 having an outer shape substantially identical to the inner shape of the displacement prevention groove 103a is inserted into the displacement prevention groove 103a. The anti-slip material 13 is fixed to the plate material 11 by a plurality of plugs 14 which penetrate the anti-slip material 13 and are driven into the plate material 11. This makes it possible to prevent the plurality of plate materials 11 from being misaligned relative to one another.

[0034] Next, the manufacturing procedure for the wooden fence panel 10 will be described. FIG. 11 is a diagram illustrating a manufacturing procedure for the wooden fence panel 10 according to the embodiment. The manufacturer manufactures the wooden fence panel 10 in a factory or the like according to the following procedure. First, the manufacturer places the second board 11 on top of the first board 11 in a position where the left side edge (the direction in which the posts 2 (see FIG. 1) are arranged) protrudes a predetermined distance S to the left from the side edge of the first board 11, for example, as shown in FIG.

[0035] Here, as described above, the drain holes H and the filters F are formed in advance at predetermined positions on the plates 11L and 11U.

[0036] 9, the protrusion 112a formed on the upper edge 112 of the first plate material 11 is fitted into the groove 111a formed in the lower edge 111 of the second plate material 11. The manufacturer then similarly places the third plate material 11 on the second plate material 11 in a position where the left side edge of the third plate material 11 protrudes leftward a predetermined distance S from the side edge of the second plate material 11, and fits the protrusion 112a formed on the upper edge 112 of the second plate material 11 into the groove 111a formed in the lower edge 111 of the third plate material 11. Then, finally, the manufacturer similarly positions the fourth plate material 11 on top of the third plate material 11 in a position where the left side edge of the fourth plate material 11 protrudes a specified distance S to the left from the side edge of the third plate material 11, and fits the protrusion 112a formed on the upper edge 112 of the third plate material 11 into the groove 111a formed on the lower edge 111 of the fourth plate material 11. As a result, the wooden fence panel 10 is formed so that its left-right width is the sum of the width dimension W of the board 11 and the three specified dimensions S, resulting in the state shown in Figure 4.

[0037] Next, as shown in Fig. 11, the manufacturer forms anti-slip grooves 103a on the rear surface 103, fits anti-slip materials 13 into the formed anti-slip grooves 103a, and drives in multiple plugs 14. At this time, by driving in multiple plugs 14 at an angle in different directions alternately with respect to the direction perpendicular to the rear surface 103, it is possible to prevent the anti-slip materials 13 from falling out of the anti-slip grooves 103a due to impact, for example, when piling up soil.

[0038] Then, at the work site, the builder of the wooden fence 1 installs the posts 2 (see FIG. 1), and then installs the wooden fence panels 10 in the following order, resulting in the state shown in FIG. For example, the contractor places a certain wooden fence panel 10 to the right of another wooden fence panel 10 (in the direction in which the posts 2 are arranged), and fits a protrusion 112a formed on an upper edge 112 of the protruding portion from the first row to the third row on the right side edge of the certain wooden fence panel 10 into a groove 111a formed on a lower edge 111 of the protruding portion from the second row to the fourth row on the left side edge of the other wooden fence panel 10.

[0039] Thus, with the wooden fence panel 10 of this embodiment, for example, the wooden fence panel 10 can be manufactured in a factory by stacking the boards 11 vertically, transported to a work site, and fixed to the posts 2. This improves the construction efficiency of the wooden fence 1 compared to attaching the boards 11 to the posts 2 one by one at a work site with poor footing.

[0040] In addition, by providing drainage holes H in the boards 11L and 11U and covering the drainage holes H with filters F, the drainage capacity of the soil B on the rear side of the wooden fence 1 can be improved.

[0041] Moreover, the plate material 11 that is stacked on top of another plate material 11 is disposed at a position where the side edge in the arrangement direction of the posts 2 protrudes a predetermined distance S in the arrangement direction from the side edge of the other plate material. As a result, the width dimension of the wooden fence panel 10 is the specified distance W plus the specified dimension S. For this reason, for example, even if the distance between the posts 2 becomes wider than the specified distance W, as long as the distance between the posts 2 is within the range of the specified distance W plus the specified dimension S, no adjustment process of adjusting the position of the posts 2 is required. Therefore, it is possible to provide a wooden fence panel 10 that reduces the number of processes at the work site and the rework process, thereby improving the construction efficiency of the wooden fence 1.

[0042] In addition, one board material 11 and another board material 11, and one wooden fence panel 10 and another wooden fence panel 10 can be connected to each other simply by engaging one lateral engagement portion 110 with the other lateral engagement portion 110, without attaching metal fittings or the like to connect them to each other. This improves efficiency in manufacturing the wooden fence panel 10 and in constructing the wooden fence.

[0043] Furthermore, according to this embodiment, in a factory, a certain plate material 11 is placed on top of another plate material 11, and, for example, a protrusion 112a formed on an upper edge 112 of the certain plate material 11 is fitted into a groove 111a formed on a lower edge 111 of the other plate material 11. The wooden fence panels 10 manufactured in this manner at the factory are then transported to the construction site of the wooden fence 1, and, for example, one wooden fence panel 10 is placed to the right of another wooden fence panel 10, and the protrusion 112a formed on the upper edge 112 at the right side edge of the one wooden fence panel 10 is fitted into the groove 111a formed in the lower edge 111 at the left side edge of the other wooden fence panel 10.

[0044] In this way, one board material 11 and another board material 11, and one wooden fence panel 10 and another wooden fence panel 10 can be connected to each other simply by fitting the protrusion 112a of one into the groove 111a of the other, without attaching metal fittings or the like to connect them to each other. This improves efficiency in manufacturing the wooden fence panel 10 and in constructing the wooden fence 1.

[0045] The present invention is not limited to the above-described embodiment, and modifications and improvements within the scope of the invention that can achieve the object of the invention are included in the present invention. [Explanation of symbols]
