  FIG. 1 is a front view showing a panel wall structure constructed using a wood panel 1 according to an embodiment of the present invention, and FIGS. 2 and 3 are side sectional views of the panel wall structure. As shown in these drawings, in the panel wall structure of the present embodiment, a strip-like wood panel 1 is placed in a horizontal direction (horizontal direction) on an indoor wall surface (indoor wall surface) W as a reference wall surface in a general house. Are arranged in parallel in the vertical direction.

  In the present embodiment, the interior wall surface panel is constituted by the wood panel 1, and the panel wall structure covering the front side of the wall surface W is constituted by a large number of constructed wood panels 1.

  In the present embodiment, the direction approaching the wall surface W from the indoor side is the rear side direction (rear surface side direction), and the opposite direction, that is, the direction away from the wall surface W is the front side direction (front surface direction). Will be described.

  Moreover, as shown in FIGS. 1-5, each wooden panel 1 is constructed so that the one side edge part 2 side is arrange | positioned below and the other side edge part 3 side is arrange | positioned upwards. Therefore, in the present embodiment, “one side edge 2” of the wood panel 1 is referred to as “lower side edge 2” and “other side edge 3” is referred to as “upper edge 3” as necessary. .

  Furthermore, in this embodiment, the opposing edge parts 2 and 3 of the adjacent wooden panels 1 and 1 are one side edge part (lower side edge part) in the upper wooden panel 1 among the wooden panels 1 and 1 adjacent to the upper and lower sides. 2 and the other side edge (upper edge) 3 of the lower wood panel 1.

  In the present embodiment, the vertical direction corresponds to the panel arrangement direction. As will be described later, the length direction (left-right direction) of the wood panel 1 corresponds to the panel joining direction.

  Hereinafter, this embodiment will be described in more detail.

  The wall surface W is configured by, for example, a large number of plywoods arranged and attached in a planar shape on the interior side of the studs and the trunk edge, and a large number of gypsum boards arranged and attached in a planar shape on the plywood. .

  The wood panel 1 is formed in a strip shape having a predetermined length. As shown in FIGS. 4A and 4B, in this embodiment, the wood panel 1 includes a front material 11 disposed on the front surface side (front surface side) and a back material laminated on the back surface side (rear surface side) of the front material 11. 12 layer structure.

  The front material 11 is constituted by a grid-like plate material (laminated ground plate material) produced using a plate material, and the backing material 12 is constituted by a plate material.

 As shown in FIG. 19, the plate material constituting the surface material 11 is constituted by a sap material 11 a also called white thick or white material located in a peripheral part (outer peripheral part) close to the bark of wood. Further, the plate material constituting the backing material 11 is constituted by a plate material including a core material 12a which is located inside (inner peripheral portion) and which is generally called a reddish or red skin having a darker color than the sap material 11a. Has been. In order to facilitate understanding of the invention, the portion corresponding to the core material 12a in the stump of FIG. 19 is hatched, and the portion corresponding to the sap material 11a is not hatched.

  As shown in FIG. 20, the surface material 11 includes a laminated plate material 11 c obtained by laminating a plurality of pieces (about 15 to 16 pieces in the embodiment) of a piece of material (a piece side piece material) 11 b made of the side material 11 a. Is formed by a laminated ground plate material 11d cut in a slice shape with a thickness of 6 mm. In other words, the laminated plate material 11c is constituted by a laminated ground plate material 11d cut in a slice shape on a plane orthogonal to the width direction of the plate edge material 11b. The width direction of the grid-like plate material as the laminated ground plate material 11d corresponds to the stacking direction of the laminated plate material 11c in FIG. 20, that is, the thickness direction of the plate edge material 11b constituting the laminated plate material 11c. The thickness direction corresponds to the width direction of the plate edge material 11b constituting the laminated plate material 11c. Needless to say, the length direction of the laminated ground plate material 11d corresponds to the length direction of the plate edge material 11b constituting the laminated plate material 11c.

  In the present embodiment, the surface material 11 is not formed by joining the laminated ground plate materials 11d, but is constituted by a so-called one piece, but the laminated ground plate material 11d is formed in the width direction or the length direction as necessary. It is also possible to use a laminated material appropriately joined together. However, in this embodiment, since the laminated ground plate material 11d is used as the surface material 11, when the seam is joined in the length direction, a seam line may be exposed on the surface along the width direction.

  Further, as shown in FIGS. 4B and 19, the backing 11 is constituted by a plate material (plate core material) 12 b including at least a part of the core material 12 a. In this embodiment, the backing 11 is made of a laminated material in which the plate core material 12b is appropriately joined in the width direction and the length direction, but is constituted by a single piece that is not joined together. Also good.

  By the way, a normal grid material has a very small expansion / contraction rate due to moisture absorption and desorption relative to a normal plate material, and therefore, there is a concern about the occurrence of warping in a laminated plate material in which a normal grid material and a normal plate material are bonded together. Is done.

  On the other hand, in this embodiment, the surface material 11 made of the laminated ground plate material 11d and the backing material 12 made of the plate core material 12b can approach the expansion / contraction rate due to moisture absorption / release, and the surface material 11 and the backing material. In the laminated board material (woody panel 1) bonded together, the occurrence of warpage can be effectively prevented.

  That is, in this embodiment, the surface material 11 is comprised by the laminated ground board material 11d which cut | judged the laminated board material 11c which laminated | stacked the board | plate edge material 11b as described above in the slice shape. As shown in FIG. 4B and the like, the laminated ground board material 11d has a memorial pattern in which thin plate patterns are aggregated, unlike a genuine pattern. That is, the laminated ground plate material 11d constituting the surface material 11 is structurally configured as a remedy material that is close to the plate material among the mesh materials. Therefore, the surface material 11 constituted by the laminated ground plate material 11 has a larger expansion / contraction rate due to moisture absorption / release than a normal mesh material, and the expansion / contraction behavior of the surface material 11 is that of the backing material 12 constituted by the plate center material 12b. It tends to approach the expansion / contraction behavior.

  On the other hand, the backing 12 is composed of a plate core material 12b. Usually, the plate material made of the core material has a lower expansion / contraction rate due to moisture absorption and desorption than the plate edge material 11b. In other words, the plate material has a large expansion and contraction rate in the annual ring direction, and the normal ring material made of sap material (plate material sap material) has a large radius of curvature of the annual ring, and the annual ring direction almost corresponds to the width direction. Therefore, it expands and contracts greatly in the width direction. On the other hand, since the radius of curvature of the annual rings 12b is small and the annual ring direction is arranged substantially corresponding to the thickness direction, the expansion / contraction ratio in the width direction of the axial centers 12b itself is reduced. Accordingly, the backing material 12 constituted by the plate core material 12b has a lower expansion / contraction rate due to moisture absorption / release than a normal plate material, and the expansion / contraction behavior of the backing material 12 is the expansion / contraction behavior of the surface material 11 of the memorial structure. It tends to approach. In addition, in the present embodiment, the core material 12b constituting the backing 12 is constituted by a core material 12a obtained by removing a core material portion of a small-diameter tree. The small-diameter wood plank core material 12b is a half plate material close to the grid material among the plank materials. Therefore, also from this point, the backing material 12 has a small expansion / contraction rate, and the stretching behavior of the backing material 12 tends to be closer to the stretching behavior of the surface material 11 of the memorial structure.

  Thus, the front material 11 has a structure of a remedy material that approximates a half plate material, and the backing material 12 is a half plate material that approximates a remedy material. In the laminated board material (wood panel 1) bonded together, warpage can be effectively prevented.

  Here, in this embodiment, the small-diameter wood refers to a wood having a diameter (end) of 40 cm or less, preferably 30 cm or less.

  In the present embodiment, the fact that the expansion ratio of the front material 11 and the back surface 12 of the wood panel 1 is approximate and that the warp does not occur in the wood panel 1 are also apparent from the following examples (experimental examples). It becomes.

  As shown in FIG. 5A, in the wood panel 1 of the present embodiment, one side edge (lower edge) 2 is cut away on the back surface side, so that the cover piece 21 is on one side (downward) on the front side. It is formed so as to protrude. A concave strip 22 extending continuously in the panel length direction is formed on the distal end surface of the cover piece 21.

  Further, a cut-out groove 23 extending continuously in the panel length direction is formed on one side edge 2 of the wood panel 1 on the back surface side (wall surface side) of the cover piece 21.

  As shown in FIG. 5B, the other side edge (upper side edge) 3 of the wood panel 1 is formed so that the front surface side cover piece 31 protrudes to the other side (upward) by notching the back surface side. Has been. On the front end surface of the cover piece 31, a ridge 32 extending continuously in the panel length direction is formed.

  Further, the other side edge portion 3 of the wood panel 1 is formed with a cut groove 33 extending continuously in the panel length direction on the back surface side (wall surface side) from the cover piece 31.

  On the other hand, as shown in FIGS. 6 to 10, the panel mounting jig 5 includes a jig body 6 that is fixed to the wall surface W and an adapter 7 that is detachably attached to the jig body 6.

  In the following description, the vertical direction is described as “vertical direction” and the horizontal direction (horizontal direction) is described as “horizontal direction (horizontal direction)” in FIG. 8B, the left side is described as “front (front side)” and the right side is described as “rear (back side)”. The same applies to the jig body 6 of FIG. 9 and the adapter 7 of FIG.

  The jig body 6 has a rectangular shape when viewed from the front (see FIG. 9A). In the present embodiment, the jig body 6 is fixed to the wall surface W with the length direction aligned with the horizontal direction (horizontal direction). Is. In the present embodiment, of the side edges of the jig body 6, one side edge is disposed on the lower side to form the lower edge, and the remaining one (the other) side edge is disposed on the upper side. As a result, the upper edge portion is formed.

  The jig body 6 is constituted by, for example, an integrally molded product of hard synthetic resin. On the surface side of the jig body 6, an adapter mounting groove 65 that extends continuously in the length direction and is open at both ends in the length direction is formed. At the front ends of the upper and lower side walls of the adapter mounting groove 65, a plurality of retaining protrusions 66 projecting in a manner of closing both the upper and lower sides of the front surface side (front surface side) opening of the adapter mounting groove 65 are formed.

  Further, a lower rear position support projecting downward on the lower side wall, that is, the lower side edge portion of the upper and lower side walls of the adapter mounting groove 65 and extending continuously in the length direction (lateral direction) of the jig body 6. A piece 62 is formed, and an upper rear position support piece 63 that protrudes upward and extends continuously in the length direction of the jig body 6 is formed on the upper side wall, that is, the upper edge. The rear position support pieces 62 and 63 can be inserted into the cut grooves 23 and 33 of the side edges 2 and 3 of the wood panel 1 so that the panel 1 can be supported.

  In the present embodiment, as will be described later, in the state where the jig body 6 is fixed to the wall surface W, both the rear position support pieces 62 and 63 have the same separation distance (separation dimension) from the wall surface W. ing.

  In the present embodiment, the lower rear position support piece 62 and the upper rear position support piece 63 each constitute a support piece member.

  Further, on the upper portion of the bottom wall of the adapter mounting groove 65 of the jig body 6, three screw retaining holes 67 that penetrate the bottom wall and are arranged at predetermined intervals in the length direction are formed. . Further, a dividing line portion 68 that extends continuously in the length direction and is formed in a thin shape is formed on the lower side portion of the bottom wall of the adapter mounting groove 65 of the jig body 6. As will be described in detail later, the jig main body 6 is split at the dividing line portion 68 as shown in FIG. 63 and a first divided body 6 a including a screw retaining hole 67 and a second divided body 6 b including a lower rear position support piece 62 can be divided.

  In the present embodiment, in the jig main body 6, the lower rear position support piece 62 and the upper rear position support piece 63 have a vertically symmetric shape, and are fixed to the wall surface W by being inverted vertically. Both the rear position support pieces 62 and 63 can be supported on both side edges 2 and 3 of the wood panel 1.

  The adapter 7 is constituted by an integrally molded product of hard synthetic resin or the like, similar to the jig body 6. The adapter 7 includes a rectangular slide plate 75 in a front view (see FIG. 10A). The slide plate 75 can be slidably accommodated along the groove direction (lateral direction) by being inserted into the adapter mounting groove 65 of the jig body 6 from both ends open. Further, in this accommodated state, by engaging with the retaining pieces 66, 66 of the jig body 6, it is prevented from coming out forward.

  At the center of the slide plate 75 in the left-right direction (slide direction), two screw retaining holes 77 that pass through the slide plate 75 and are arranged side by side are formed.

  A front projecting piece 71 is formed on the upper edge of the front surface of the slide plate 75 in the adapter 7 so as to extend obliquely upward toward the front and continuously in the lateral direction. The front protruding piece 71 is formed with a front position supporting piece 72 that protrudes upward and continuously extends in the lateral direction. The front position support piece 72 can be inserted into the cut grooves 23 and 33 of the side edges 2 and 3 of the wood panel 1 so that the panel 1 can be supported.

  As shown in FIGS. 6 and 8, when the slide plate 75 is accommodated in the adapter mounting groove 65 of the jig body 6 so that the front position support piece 72 is arranged on the upper side in the adapter 7. The front position support piece 72 of the adapter 7 is disposed in front of the upper rear position support piece 63 of the jig main body 6 at the position corresponding to the upper edge of the jig main body 6 (on the front side). It has become. Accordingly, in this state, when the panel mounting jig 5 is fixed to the wall surface W, as will be described later, the front position support piece 72 of the adapter 7 is positioned on the wall surface W with respect to the upper rear position support piece 63 of the jig body 6. The distance away from is increased and is arranged forward.

  Moreover, in this embodiment, it is also possible to attach the adapter 7 to the jig main body 6 by turning the adapter 7 upside down. That is, as shown in FIG. 12, in this adapter 7, when the slide plate 75 is accommodated in the adapter mounting groove 65 of the jig body 6 so that the front position support piece 72 is disposed on the lower side, The front position support piece 72 of the adapter 7 is arranged in front (front side) of the lower rear position support piece 62 of the jig body 6 at a position corresponding to the lower edge of the jig body 6. ing. In this state, as described later, when the panel mounting jig 5 is fixed to the wall surface W, the front position support piece 72 of the adapter 7 is separated from the lower rear position support piece 62 of the jig body 6 from the wall surface W. The separation distance is increased and is arranged forward.

  Furthermore, in the present embodiment, in a state where the adapter 7 is accommodated in the adapter mounting groove 65 of the jig body 6, the screw fixing hole 77 disposed on the upper side of the adapter 7 is made to slide by operating the adapter 7. It can be adapted to any of the three screw fixing holes 67 of the main body 6. Note that the adapter 7 has the upper and lower screw-fastening holes 77 in the state in which the panel support piece 72 is arranged on the upper side as shown in FIG. 8 or in the state in which the panel support piece 72 is arranged on the lower side as shown in FIG. Among them, the screw fixing hole 77 arranged on the upper side corresponds to the screw fixing hole 67 of the jig body 6.

Either one of the attachment forms of the attachment form attached to the jig main body 5 with the support piece 72 facing downward is configured as the first attachment form, and the other attachment form is the second attachment form. It is composed.

  In this embodiment, the panel mounting jig 5 having the above-described configuration is used to construct the wooden panel 1 on the wall surface W so that a plurality of the wooden panels 1 are arranged in the vertical direction with the length direction set in the horizontal direction.

  In this case, for example, as shown in FIG. 2 and FIG. 3, a panel wall structure constructed by applying a look so that each wooden panel 1 is arranged obliquely upward, and each wooden panel 1 as shown in FIG. 14 and FIG. Panel wall structure constructed by flat bonding so as to be arranged on the same plane, panel wall structure constructed by uneven bonding so as to project any wooden panel 1 forward as shown in FIGS. 16 and 17, etc. Many kinds of panel wall structures can be constructed.

  First, as shown in FIG. Needless to say, in the present invention, the construction procedure is not limited to that of the following embodiment, and any construction procedure may be used.

  For example, in the case of performing the preview attachment in order from the lower side, a plurality of the panel attachment jigs 5 are attached at predetermined intervals in the lateral direction at positions corresponding to the lower edge of the panel attachment scheduled area on the wall surface W.

  In this case, as shown in FIG. 8, in each panel mounting jig 5, the adapter 7 is accommodated in the adapter mounting groove 65 of the jig body 6 so that the front position support piece 72 is disposed on the upper side. Further, the adapter 7 is arranged at an intermediate position in the lateral direction with respect to the jig main body 6, and the screw fixing hole 77 on the upper side of the adapter 7 is arranged corresponding to the screw fixing hole 67 at the center of the jig main body 6. In this state, the screws 8 are inserted into the screw fixing holes 77 and 67 and screwed into the wall surface W to fix the panel mounting jig 5 to the wall surface W.

  In this way, the plurality of panel mounting jigs 5 are fixed at predetermined intervals along the lower edge of the panel pasting area on the wall surface W.

  Next, by inserting the front position support piece 72 of the adapter 7 in each panel mounting jig 5 into the cut groove 23 in the lower edge 2 of the wood panel 1 arranged at the lowermost end, the wood panel 1 is supported by each panel mounting jig 5.

  In this way, the upper edge 3 of the lowermost wood panel 1 is fixed to the wall surface W via the plurality of panel mounting jigs 5.

  In this mounted state, the lower edge 2 of the wood panel 1 is supported by the front position support piece 72 of the adapter 7 in the panel mounting jig 5, and the upper edge 3 is the lower rear of the jig body 6. It is supported by the position support piece 62. As described above, the front position support piece 72 of the adapter 7 is disposed in front of the rear position support pieces 62 and 63 of the jig body 6, and the separation distance from the wall surface W is longer. Accordingly, the wood panel 1 is arranged in an obliquely upward (look-down paste) form so that the lower edge 2 is farther away from the wall surface W than the upper edge 3.

  Next, the lower edge of the wood panel 1 in which the front position support piece 72 of the adapter 7 in the panel mounting jig 5 that supports the upper edge 3 of the wood panel 1 at the lowest end is arranged second from the bottom. 2, the lower edge 2 of the second wood panel 1 is fixed to the wall surface W via the panel mounting jig 5. In this mounted state, the lower rear position support piece 62 of the panel mounting jig 5 is not used.

  Further, the upper edge 3 of the second wood panel 1 is fixed to the wall surface W via the panel mounting jig 5 in the same manner as the wood panel 1 at the lowermost end.

  In the same manner, the wooden panels 1 are fixed to the wall surface W via the panel mounting jig 5 in order from the bottom, and the required number of wooden panels 1 are pasted over the entire panel pasting area. As a result, a panel wall structure in which a plurality of wood panels 1 are attached on the wall surface W is constructed.

  The uppermost end fixing means for fixing the upper edge 3 of the uppermost wooden panel 1 may be constituted by only a part of the panel mounting jig 5.

  That is, as the uppermost end fixing means, as shown in FIG. 11, the jig body 6 is bent at the dividing line portion 68 to be divided into the first and second divided bodies 6a and 6b, and the two divided bodies 6a and 6b are separated. Among these, the 1st division body 6a which has the screw stop hole 67 is used. Note that the second divided body 6b and the adapter 7 are not used as the uppermost end fixing means.

  The first divided body 6a is turned upside down with respect to the state shown in FIG. 11, that is, the rear position support piece 63 arranged on the upper side in the state shown in FIG. The panel support piece 63 is inserted into the cut groove 33 in the upper edge 3 of the wood panel 1 at the uppermost end. In this state, the first divided body 6a is screwed into the wall surface W by inserting the screws 8 through the screw retaining holes 67, so that the upper edge 3 of the wood panel 1 at the uppermost end is interposed via the first divided body 6a. Fix to the wall W.

  Thus, when the upper edge 3 of the wood panel 1 at the uppermost end is fixed by the panel mounting jig 5, unnecessary portions of the panel mounting jig 5, that is, the adapter 7 and the second divided body 6b are removed. By doing so, it is possible to prevent the unnecessary portion from protruding from the upper edge of the panel wall. For this reason, the fall of the aesthetics by an unnecessary site | part being visually observed can be prevented, and a favorable aesthetics can be obtained.

  Moreover, in this embodiment, when fixing the lower edge part 3 of the wooden panel 1 of the lowest end to the wall surface W, without using the 2nd division body 6b among the jig | tool bodies 6, the 1st division body 6a and You may make it fix using the adapter 7. FIG. Even in this case, similarly to the above, by removing the second divided body 6b that is an unnecessary portion, the unnecessary portion is not visually observed, and a good aesthetic appearance can be obtained.

  Further, in the present embodiment, when a plurality of wood panels 1 are attached in the lateral direction (panel length direction), the wood panels 1, 1 adjacent to each other in the lateral panel joining direction are opposed to each other. The end portion can be substantially fixed to the wall surface W by one panel mounting jig 5.

  That is, as shown in FIG. 13, when supporting the lower edges 2 and 2 of the opposite ends 1a and 1a of the wood panels 1 and 1 adjacent in the lateral direction, The adapters 7 and 7 are accommodated. At this time, the screw fixing holes 77 and 77 of the adapters 7 and 7 are made to correspond to the screw fixing holes 67 and 67 on both sides of the jig body 6, respectively. The lower edge 2 of the opposite end 1a of one of the adjacent wooden panels 1, 1 is supported by the front position support piece 72 of one adapter 7 of the two adapters 7, 7. The lower edge 2 of the opposite end 1a of the other wood panel 1 is supported by the front position support piece 72 of the other adapter 7, so that the screw holes 77, 77 of both adapters 7, 7 and the jig Screws 8 and 8 are inserted into screw retaining holes 67 and 67 on both sides of the main body 6 and screwed into the wall surface W to be fixed.

  In addition, when supporting the upper edge 3 and 3 of the opposing edge parts 1a and 1a in the wooden panels 1 and 1 adjacent to a horizontal direction, the upper edge 3 of one opposing edge 1a is used as a panel mounting jig. 5 is supported by one half of the lower rear position support piece 62 in the jig body 6 and the upper edge 3 of the other opposing end 1a is supported by the other half of the lower rear position support piece 62. To do.

  Thus, when attaching the wooden panel 1 by joining in the horizontal direction, it is possible to substantially fix the opposing end portions 1a, 1a of the adjacent wooden panels 1, 1 to the wall surface W by one panel mounting jig 5. it can.

  In the panel wall structure shown in FIG. 2 described above, each wooden panel 1 is constructed in a form of sneaking pasted in a diagonally upward direction. However, in this embodiment, each wooden panel 1 is arranged in a diagonally downward direction (sneak preview). It can also be constructed in the reverse form).

  In this case, the panel mounting jig 5 is configured as shown in FIG. That is, the adapter 7 is accommodated in the adapter mounting groove 65 of the jig body 6 in the panel mounting jig 5 so that the front position support piece 72 is disposed on the lower side. And while supporting the lower edge 2 of the wood panel 1 arrange | positioned above among the wood panels 1 and 1 adjacent to the upper and lower sides by the upper back position support piece 63 of the jig main body 6 in the panel attachment jig 5, The upper edge 3 of the wood panel 1 disposed on the lower side is supported by the front position support piece 72 of the adapter 7 in the panel mounting jig 5. Thereby, the panel wall which has arrange | positioned each wooden panel 1 diagonally downward can be constructed | assembled. In this embodiment, the lower rear support piece 62 of the jig body 6 is not used.

  Further, in this embodiment, each panel mounting jig 5 is configured as shown in FIG. 12, but is not limited thereto, and the entire panel mounting jig 5 shown in FIG. 8 is inverted and fixed to the wall surface W. By this, it can construct in the same form as the above (form opposite to the appearance paste).

  Furthermore, even when the panel is installed obliquely downward (in the form opposite to the appearance of the underlay), the panel mounting jig 5 arranged at the lowermost end or the uppermost end removes the divided body 6b, the adapter 7 and the like as necessary. May be fixed.

  On the other hand, in this embodiment, each wooden panel 1 can be applied in a flat-attached form in parallel with the wall surface W.

  In this case, as shown in FIGS. 14 and 15, only the jig body 6 is used as the panel mounting jig 5 without using the adapter 7. That is, the lower edge 2 of the wood panel 1 disposed on the upper side of the wood panels 1 and 1 adjacent to each other is supported by the upper rear position support piece 63 of the jig body 6 and disposed on the lower side. The upper edge 3 of the wood panel 1 is supported by the lower rear position support piece 62 of the jig body 6. Thereby, the flat panel wall surface in which each wooden panel 1 is arrange | positioned on the same plane is formed.

  When the adjacent wooden panels 1 and 1 are arranged in parallel to the wall surface W in this way, the lower wooden panel 1 is located in the concave strip 22 at the lower edge 2 of the upper wooden panel 1. The ridge part 32 in the upper side edge part 3 is arrange | positioned (refer FIG. 15). As a result, no gap is formed between the adjacent wooden panels 1 and 1.

  In addition, in this embodiment, even if it is a form of flat bonding, each wooden panel 1 is not contacting with respect to the wall surface W, and is spaced apart a little.

  In this embodiment, it can also construct in the form of uneven | corrugated pasting which raises one wooden panel 1 among the several wooden panels 1 constructed with respect to the other wooden panel 1 ahead.

  In this case, as shown in FIGS. 16 and 17, the other wood panel 1 that does not float forward is fixed to the wall surface W in the same manner as in the flat pasting form (see FIGS. 14 and 15). Further, the panel mounting jig 5 that supports the lower edge 2 of the wood panel 1 that floats forward is arranged in the adapter mounting groove 65 of the jig body 6 and the adapter 7 in the front position support piece 72 on the upper side. (See FIG. 8). Then, the lower edge 2 of the wood panel 1 is supported by the front position support piece 72 in the panel mounting jig 5. Further, the panel mounting jig 5 that supports the upper edge 3 of the wood panel 1 that floats forward is arranged in the adapter mounting groove 65 of the jig main body 6, and the adapter 7 is disposed with its front position support piece 72 below. (See FIG. 12). Then, the upper edge 3 of the wood panel 1 is supported by the front position support piece 72 in the panel mounting jig 5. In addition, in uneven | corrugated sticking form, although the panel attachment jig | tool 5 which supports the upper edge 16 of the wood panel 1 which floated ahead is made into the form shown in FIG. 12, it is not restricted only to it, The panel attachment treatment of the form shown in FIG. By reversing the whole tool 5 up and down and fixing it to the wall surface W, it can be constructed in the form of uneven bonding similar to the above.

  As a result, the upper and lower side edges 2 and 3 of the predetermined wooden panel 1 are supported by the front-position support pieces 72 and 72 of the adapters 7 and 7 in the panel mounting jigs 5 and 5. The other wood panel 1 arranged parallel to the wall surface W and supported by the rear position support pieces 62 and 63 of the jig body 6 is arranged in a state of being lifted forward.

  In addition, when constructing in the form of uneven bonding in this way, the wooden panel 1 is lifted every other one, the wooden panel 1 is lifted every two, or the wooden panel 1 is lifted every three or more. It is possible to form regular irregular shapes so that the wooden panel 1 is raised irregularly as appropriate. Further, two or more wood panels 1 continuous in the vertical direction may be lifted together.

  When the wooden panels 1, 1 adjacent to each other are lifted together, the panel mounting jig 5 disposed between the panels 1, 1 is, for example, two adapters 7 attached to one jig body 6. One adapter 7 has its front position support piece 72 disposed above, and the other adapter 5 has its front position support piece 72 disposed below. The front edge support piece 72 of one adapter 7 supports the lower edge 2 of the upper wood panel 1, and the front edge support piece 72 of the other adapter 7 supports the upper edge 3 of the lower wood panel 1. You can make it. Alternatively, the panel mounting jig 5 shown in FIG. 8 and the panel mounting jig 5 shown in FIG. 12 are alternately arranged between the wood panels 1 and 1, and the panel mounting jig 5 shown in FIG. The lower edge 2 of the upper wood panel 1 is supported by the front position support piece 72, and the upper edge 3 of the lower wood panel 1 is supported by the front position support piece 72 of the panel mounting jig 5 of FIG. You can do it.

  When installing a plurality of wooden panels 1 in the horizontal direction, either one of the wooden panels 1 arranged in the horizontal direction may be lifted, or all the wooden panels 1 arranged in the horizontal direction may be lifted. May be.

  As described above, according to the panel wall structure of the present embodiment, a wide variety of forms such as a stencil paste form, a reverse form to a stencil paste, a flat paste form, a regular uneven paste form, and an irregular uneven paste form are provided. In the form, the wood panel 1 can be attached to the wall surface W, and the wood panel 1 can be attached in a form according to the indoor situation and the resident's preference.

  Further, in the above embodiment, if only the jig body 6 is used without attaching the adapter 7, it can be applied by flat bonding, so it is necessary to separately prepare a panel mounting means (panel mounting jig) dedicated to flat bonding. Therefore, it is possible to reduce the number of parts and the cost by sharing the members.

  Further, the wood panel 1 employed in the present embodiment is composed of a laminate having a two-layer structure of a front material 11 and a backing material 12, and thus a three-layer laminate generally used for wood panels conventionally. Compared to the above, the structure is simplified, the cost can be reduced, and the device can be easily manufactured.

  Furthermore, since the surface material 11 and the back material 12 constituting the wood panel 1 of this embodiment are made of the easy-to-obtain and cheap plate materials 11b and 12b as compared with the normal mesh material, the cost can be further reduced. Can be planned.

  Furthermore, since the backing 12 uses a grain material 12b made of a core material 12a having low utilization as high-grade wood, resources can be used effectively and costs can be further reduced. Can do.

  In addition, since the surface material 11 of the wood panel 1 of the present embodiment is constituted by the laminated ground plate 11d obtained by laminating the plate side materials 11b and cutting the sliced material 11b, the surface material 11 of a good color tone is displayed. It is possible to build a high-class and heavy panel wall.

  Moreover, although the woody panel 1 of this embodiment is a laminated body of 2 layer structure, generation | occurrence | production of curvature can be prevented effectively.

  That is, the laminate having a two-layer structure has a different tension balance between the front and back surfaces, and thus warp easily occurs.

  Therefore, the wood panel 1 of the present embodiment approximates the expansion / contraction behavior at the time of moisture absorption / release in the front material 11 and the backing material 12 as described above, and thus can prevent the occurrence of warpage and is good. Beautiful aesthetics can be maintained for a long time.

  Moreover, in this embodiment, when the wooden panel 1 is attached in a state of being separated from the wall surface W, the back surface side of the backing 12 is also in contact with the room air, so that the contact area of the wooden panel 1 with the room air is large. Become. For this reason, the humidity control performance which holds the timber itself which comprises the wood panel 1 can fully be exhibited, and a comfortable living space can be obtained.

  When the wood panel 1 is attached in a state of being separated from the wall surface W, the backing 12 is also easily affected by moisture absorption / release. In such a case, if the expansion and contraction behaviors of the surface material 11 and the backing material 12 are different, warping is more likely to occur. However, in the wood panel 1 of the present embodiment, as described above, Since the expansion / contraction behavior with the backing 12 is approximate, even if the back surface 12 is separated from the wall surface W, the occurrence of warpage can be effectively prevented.

  Moreover, in this embodiment, it is preferable to adjust the moisture content to 4% to 8% in advance by performing high-temperature drying or the like on the front material 11 and the back material 12 constituting the wood panel 1. That is, by adjusting the moisture content within this range, it is possible to more reliably prevent warpage in the wood panel 1. This point will become clear from the following examples.

  Here, in the present embodiment, in order to sufficiently bring out a profound feeling and a high-class feeling, the total thickness of the wood panel 1 is preferably set to 9 mm to 30 mm, more preferably 13 mm to 23 mm. Furthermore, in order to form a pattern with a profound feeling and a high-class feeling by engraving on the surface material 11, the thickness of the surface material 11 is preferably set to 3 mm to 10 mm, more preferably 5 mm to 8 mm. Further, considering the balance with the surface material 11 and the like, the thickness of the backing 12 is preferably set to 6 mm to 20 mm, more preferably 8 mm to 15 mm.

  In the above embodiment, the case where the wood panel 1 is constructed with its length direction aligned in the horizontal direction (horizontal direction) and arranged in the vertical direction has been described as an example. However, the present invention is not limited thereto. In this case, the wood panel 1 may be constructed such that its length direction coincides with the vertical direction (vertical direction) and is arranged in the left-right direction (horizontal direction). Furthermore, you may make it construct so that the length direction of the wood panel 1 may correspond with the direction which inclines with respect to a perpendicular direction or a horizontal direction.

  Moreover, in the said embodiment, although the thing of strip | belt board shape or a long board shape is used as the wood panel 1, it is not restricted only to it, In this invention, it is also possible to use a square-shaped wood panel.

  Further, in the above embodiment, the panel mounting jig 5 such as the jig main body 6 and the adapter 7 is constituted by an integrally molded product of hard synthetic resin, but in the present invention, the materials of these members are particularly limited. You may make it comprise not a thing but the metal processed goods.

  Next, examples relating to the front material 11 and the back material 2 of the interior wall panel (woody panel) 1 of the present invention will be described.

  <Examples regarding dimensional change rate>

  As shown in Table 1, the laminated ground board material 11d which can be used as the surface material 11 of the wood panel 1 was prepared. That is, as shown in FIG. 20, similarly to the above-described embodiment, the laminated plate material 11c obtained by laminating the plate edge materials 11b is cut into slices at predetermined intervals in a form in which the lamination direction is the width direction. A total of 20 grid-like plate materials (laminated ground plate materials) 11d of A1 to A20 were prepared. For example, the laminated ground board material 11d of sample No. A1 has an initial weight of 63.38 g, an initial size of length 100.64 mm × width 153.17 mm × thickness 10.40 mm, weight after total drying is 53.45 g, After drying, the size was 99.86 mm length × 149.48 mm width × 9.87 mm thickness. The moisture content of the laminated ground plate material 14d = “(initial weight−weight after total drying) / weight after total drying × 100” is 18.6%. Further, the dimensional change rate of length (per 1% moisture content, the same applies hereinafter) = “(initial length−length after total drying) / initial length × 100 / water content” is 0.04 [% /%]. Dimension change rate of width = “(initial width−width after total drying) / initial width × 100 / water content” is 0.13 [% /%], dimensional change rate of thickness = “(initial thickness−total dryness” “Post-thickness) / initial thickness × 100 / water content” is 0.27 [% /%].

  Moreover, each weight, each size, each moisture content, and each dimensional change rate in the laminated ground board material 11d for sample Nos. A2 to A20 are as shown in Table 1.

  As shown in Table 2, the width laminated board material which can be used as the backing material 12 of the wood panel 1 was prepared. That is, similarly to the above-described embodiment, the plate core material 12b was appropriately joined in the width direction to prepare a total of 20 width laminated plate materials of sample Nos. B1 to B20. For example, the width laminated plate material of sample No. B1 has an initial weight of 59.13 g, an initial size of 99.85 mm long × 157.58 mm wide × 9.40 mm thick, and a total weight of 51.08 g after total drying. The rear size was 99.63 mm long × 152.91 mm wide × 9.23 mm thick. The moisture content of the width laminated material (sheet core material 12b) = “(initial weight−weight after total drying) / weight after total drying × 100” is 15.8%. Further, dimensional change rate of length = “(initial length−length after total drying) / initial length × 100 / water content” is 0.01 [% /%], dimensional change rate of width = “(initial Width-width after full drying) / initial width × 100 / water content ”is 0.19 [% /%], dimensional change rate of thickness =“ (initial thickness−thickness after full drying) / initial thickness × 100 / water content ” The “rate” is 0.11 [% /%].

  Table 2 shows the weights, sizes, moisture contents, and dimensional change rates of the backing width laminated sheets of Sample Nos. B2 to B20.

  As is clear from Tables 1 and 2, the laminated ground plate material 11d for the front material and the width laminated plate material for the back material (plate centering material 12b) are not significantly different in dimensional change rate. In the wood panel of the present invention, which is a laminated plate material obtained by bonding the plate materials 11d and 12b, it is considered that the expansion / contraction behavior at the time of moisture absorption / release is approximate, and the occurrence of warpage can be effectively prevented. In particular, the dimensional change rates in the width direction of the laminated ground board material 11d for the front material and the width laminated board material for the backing material are close to each other, and the wood panel of the present invention constituted by these laminated board materials has a width of It is considered that direction warping can be prevented more reliably.

  For reference, a plate material related to the wood panel of the present invention and a plate material used for a general wood panel are as follows.

  In Table 3, Example 1 is the laminated ground plate material 11d for the surface material shown in the samples A1 to A20, and the dimensional change rate in the width direction is 0.14 for the average, 0.17 for the maximum, and 0 for the minimum. .11. Moreover, Example 2 is the width | variety laminated | stacked board | plate material (plate center material 12b) for the backing shown to the said samples B1-B20, The average dimensional change rate is 0.14, the maximum is 0.20, and the minimum Is 0.13. Thus, since the dimensional change rate of the board | plate materials 11d and 12b of Example 1, 2 is very approximate, in the laminated board material (wooden panel) which bonded the board | plate materials 11d, 12b of Example 1, 2, it warps. It is thought that the occurrence of the occurrence can be effectively prevented.

  On the other hand, in Table 3, Reference Example 1 is a cedar grid material that can be used as a surface material of a general wood panel, and the dimensional change rate in the width direction is 0.21 at the maximum and 0.05 at the minimum. is there. Reference Example 2 is a cedar plate material that can be used as a backing material for a general wood panel, and the dimensional change rate in the width direction was 0.34 at the maximum and 0.21 at the minimum. As described above, the dimensional change rates in the both plate materials of Reference Examples 1 and 2 are greatly different, and in the laminated plate material (wood panel) obtained by bonding the plate materials of Reference Examples 1 and 2, there is a possibility that harmful warping may occur. It is considered high.

  In addition, as a result of including these examples and other experimental examples, in the wood panel of the present invention, the dimensional change rate [% /%] in the width direction of the surface material 11 is 0.1 to 0.2, preferably When adjusted to 0.11 to 0.17, the dimensional change rate [% /%] in the width direction of the backing 12 was further adjusted to 0.1 to 0.25, preferably 0.13 to 0.20. In this case, it is considered that the occurrence of warpage can be more effectively suppressed.

<Example of the relationship between warpage and moisture content>
FIG. 18A is a graph showing the temporal change of the width warp due to moisture absorption in the wood panel 1 of the example related to the present invention, and FIG. 18B is a graph showing the time change of the width warp due to moisture release of the wood panel 1 of the example. As shown in these graphs, as Example 11, a two-layer in which a surface material (laminated ground board material) 11 having a moisture content of 5% and a backing material (width laminated material) 12 having a moisture content of 10% are bonded together. As a wood panel 1 of the structure, Example 12, a two-layer structure in which a surface material (laminated ground board) 11 having a moisture content of 5% and a backing material (width laminated material) 12 having a moisture content of 5% are bonded together As a wood panel 1, Example 13, a two-layer wood panel in which a surface material (laminated ground board) 11 having a moisture content of 10% and a backing material (width laminated material) 12 having a moisture content of 10% are bonded together 1. As Example 14, a wood panel 1 having a two-layer structure in which a surface material (laminated ground board) 11 having a moisture content of 10% and a backing material (width laminated material) 12 having a moisture content of 5% are bonded together Got ready.

  And as shown to FIG. 18A, the wood panel 1 of Examples 11-14 was left to stand for 11 days in a moisture absorption (wet) environment, and the width curvature of each wood panel 1 was measured.

  Furthermore, as shown to FIG. 18B, the wood panel 1 of Examples 11-14 was left to stand for 11 days in moisture-release (dry) environment, and the width curvature of each wood panel 1 was measured.

  As is clear from these graphs, the wood panels 1 of Example 12 having a low moisture content with low moisture content of the front material 11 and the backing material 12 have other wood properties of Examples 11, 13, and 14 with high moisture content. Compared with panel 1, the occurrence of warping was suppressed.

  As a result of including these Examples and other experimental examples, in the wood panel of the present invention, the moisture content was adjusted to a low moisture content of 6% ± 2% by high-temperature drying of the front material 11 and the backing material 12. In this case, it seems that the occurrence of warpage can be more effectively suppressed.

  The interior wall surface panel of the present invention can be used when a panel wall is constructed on an indoor wall surface.
