DETAILED DESCRIPTION OF THE INVENTION

[0020] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the embodiments described below are subject to various limitations that are technically preferable for carrying out the present invention, but the technical scope of the present invention is not limited to the following embodiments and illustrated examples. Note that directions (up-down direction, left-right direction, front-rear direction) in the following embodiments and illustrated examples are set solely for the convenience of explanation.

[0021] <Wall panel> 1 and 2, the reference numeral 1 denotes a wall panel. This wall panel 1 is an architectural wood panel that constitutes a waist wall, and its height is adjustable, specifically, its height can be shortened. That is, the wall panel 1 before its height is adjusted (hereinafter referred to as "wall panel 1 before height adjustment") can be used as an architectural wood panel that constitutes a waist wall, and the wall panel 1 after its height is adjusted (hereinafter referred to as "wall panel 1 after height adjustment") can be used as an architectural wood panel that constitutes a waist wall. FIG. 1 is a diagram showing an example of a wall panel 1 before height adjustment in this embodiment, and FIG. 2 is a diagram showing an example of a wall panel 1 after height adjustment in this embodiment.

[0022] As shown in Figure 1, the wall panel 1 is a lattice panel made up of a pair of opposing horizontal members (upper and lower frames) 2 and a plurality of vertical members (vertical frames, vertical crosspieces) 3 provided between the pair of horizontal members 2. Unlike ordinary architectural wood panels (architectural wood panels with facings attached to one or both sides), the wall panel 1 does not have a facing. That is, the wall panel 1 is used as an architectural wood panel that constitutes a wall that does not require structural strength, and therefore does not require a facing material. Therefore, the wall panel 1 does not have a facing material, which has the advantages of being less expensive and lighter than ordinary architectural wood panels. Furthermore, with ordinary architectural wood panels, holes for wiring and piping (wiring route holes, piping route holes) must be formed in the facing material at the construction site, etc., but the wall panel 1 does not have a facing material, so there is no need to form such holes at the construction site, etc., and it also has the advantage of being easier to install wiring and piping than ordinary architectural wood panels.

[0023] As shown in FIG. 1, the wall panel 1 has, as vertical members 3, a first vertical member 31 located on the leftmost side (furthest from one side) in the left-right direction (horizontal direction), a second vertical member 32 located on the rightmost side (furthest from the other side) in the left-right direction, and a plurality of third vertical members 33 located between the first vertical member 31 and the second vertical member 32. The horizontal member 2 has a protruding portion 2a that protrudes outward (to one side) beyond the first vertical member 31. Specifically, for example, as shown in FIG. 1 , the right end face (other end face) of the horizontal member 2 is substantially flush with the right side face (other side face) of the second vertical member 32, whereas the left end face (one end face) of the horizontal member 2 is located to the left (one side) of the left side face (one side face) of the first vertical member 31.

[0024] As shown in Figure 2, the wall panel 1 after height adjustment is an architectural wood panel obtained by dividing the wall panel 1 before height adjustment into an upper part 1U and a lower part 1D in the vertical direction (longitudinal direction), and joining the sides of each vertical member 3 in the upper part 1U and each vertical member 3 in the lower part 1D. In this embodiment, before joining the upper portion 1U and the lower portion 1D, one of the upper portion 1U and the lower portion 1D is flipped left and right so that the second vertical member 32 of the upper portion 1U faces the protruding portion 2a of the lower portion 1D (i.e., the second vertical member 32 of the lower portion 1D faces the protruding portion 2a of the upper portion 1U), and then the side surfaces of each vertical member 3 in the upper portion 1U and each vertical member 3 in the lower portion 1D are joined together. Therefore, in the wall panel 1 before the height adjustment, the upper protruding portion 2a and the lower protruding portion 2a protrude in the same direction, whereas in the wall panel 1 after the height adjustment, the upper protruding portion 2a and the lower protruding portion 2a protrude in opposite directions.

[0025] The protruding dimension (length in the left-right direction) of the protruding portion 2a is set to be approximately the same as the width dimension (length in the left-right direction) of the second vertical member 32. Therefore, after the height adjustment, both upper and lower ends of the side surfaces (left side and right side) of the wall panel 1 can be directly fixed to the wall (wall panel) adjacent to the wall panel 1, which has the advantage of making the installation easier than when one upper or lower end can be directly fixed but the other upper or lower end cannot be directly fixed (for example, when the protruding portion 2a is added later as shown in Figure 13 described later).

[0026] That is, in this embodiment, in order to enable both the upper and lower ends of the side surfaces (left and right surfaces) of the wall panel 1 to be directly fixed to the wall (wall panel) adjacent to the wall panel 1 even after the height is adjusted, the following two conditions are satisfied: (1) one end (the end on the first vertical member 31 side) of the upper and lower horizontal members 2 is made to protrude beyond the first vertical member 31, and the protruding dimension is made approximately the same as the width dimension of the second vertical member 32; and (2) one of the upper part 1U and the lower part 1D is turned over (flipped left to right) and then the upper part 1U and the lower part 1D are joined together.

[0027] In this embodiment, the first vertical member 31, the second vertical member 32, and the third vertical member 33 are set to have approximately the same width dimension (length in the left-right direction), but this is not limiting. In this embodiment, the horizontal members 2 and the vertical members 3 are set to have substantially the same thickness dimension (length in the front-rear direction), but this is not limitative. In addition, the number of third vertical members 33 is not limited to multiple, and for example, as shown in Figures 3(a) and 3(b), the wall panel 1 may include one third vertical member 33. In addition, the wall panel 1 may include at least the first vertical member 31 and the second vertical member 32, and may not include the third vertical member 33. Furthermore, the width dimension (length in the left-right direction) of the wall panel 1 can be changed as appropriate, for example, as shown in FIG. 1(a) or FIGS. 3(a) and (b).

[0028] In addition, in this embodiment, the height dimension (length in the vertical direction) of the wall panel 1 before the height adjustment is set to 1365 mm, but this is not limited to this. The height dimension of the wall panel 1 before height adjustment may be a dimension that allows it to be used as a wall panel that constitutes a floor-to-ceiling partition wall. In this case, the wall panel 1 before height adjustment can be used as an architectural wood panel that constitutes a floor-to-ceiling partition wall, and the wall panel 1 after height adjustment can be used as an architectural wood panel that constitutes a waist wall or a hanging wall.

[0029] As shown in Figures 1 and 3, a plurality of reinforcing members (joists) 4 are temporarily fixed to the wall panel 1. Specifically, the reinforcing member 4 is temporarily fixed (fixed so as to be easily removed) to one of the upper and lower horizontal members 2 that make up the wall panel 1 (for example, the horizontal member 2 in the lower portion 1D) while being arranged between adjacent vertical members 3. The length dimension (length in the left-right direction) of the reinforcing member 4 is set to be approximately the same as the spacing dimension between adjacent vertical members 3. This reinforcing member 4 is used as an auxiliary crosspiece (horizontal crosspiece). That is, as shown in Fig. 2, for example, the reinforcing member 4 is removed from the horizontal member 2, and is then bridged between adjacent vertical members 3 and fixed (mainly fixed) in a state where it is spaced apart from both the upper horizontal member 2 and the lower horizontal member 2. In addition, this reinforcing material 4 can also be used as a fixing base when fixing a kitchen table K, cabinet 20, etc. to a wall formed by wall panel 1, as shown in Figure 9(b) and Figures 10(a) and (b) described below.

[0030] <Wall construction method> An example of a wall construction method in this embodiment will be described with reference to FIGS. Here, we will explain a method for constructing a waist wall 10 installed in a kitchen (kitchen room). This kitchen is a face-to-face kitchen with a kitchen counter K that allows work to be done while facing the dining room (dining room). This waist wall 10 is an L-shaped waist wall in plan view, and the kitchen counter K is installed so that a corner of the kitchen counter K (one of the corners on the dining room side) fits into a recessed corner of the L-shaped waist wall 10 in plan view. The waist wall formed by the wall panel 1 is not limited to a waist wall that is L-shaped in plan view. In addition, the waist wall formed by the wall panel 1 is not limited to a waist wall installed in a kitchen.

[0031] First, as shown in FIG. 4(a), the wall panel 1 before height adjustment is prepared at the construction site. Furthermore, based on the design dimensions of the waist wall 10, the height dimension of the wall panel 1 constituting the waist wall 10 is determined, and based on the determined height dimension, the cutting position when dividing the wall panel 1 before height adjustment into upper and lower parts (dividing into an upper part 1U and a lower part 1D) is determined (determination step). Next, as shown in FIG. 4(b), the wall panel 1 before the height adjustment is cut at the cutting position determined in the determining step to divide it into an upper portion 1U and a lower portion 1D (cutting step).

[0032] 5(a), the upper portion 1U is reversed left to right (left to right reversing step). Note that in the left to right reversing step, the lower portion 1D may be turned over (reversed left to right) instead of the upper portion 1U. Next, as shown in Figure 5(b), the side surfaces of the vertical members 3 (31, 32, 33) in the upper portion 1U and the side surfaces of the vertical members 3 (31, 32, 33) in the lower portion 1D are joined together using connectors (screws, etc.), adhesive, or a combination of these (joining step). This forms the wall panel 1 with the height dimension determined in the determination step (height-adjusted wall panel 1).

[0033] In this embodiment, a left-right inversion step is performed before the joining step, so that in the joining step, the first vertical member 31 in the upper portion 1U and the second vertical member 32 in the lower portion 1D are joined, and the first vertical member 31 in the lower portion 1D and the second vertical member 32 in the upper portion 1U are joined. In addition, in the joining step, the upper part 1U and the lower part 1D are joined in a state in which the protruding portion 2a of the horizontal member 2 in the upper part 1U faces the cut surface of the second vertical member 32 in the lower part 1D, and the protruding portion 2a of the horizontal member 2 in the lower part 1D faces the cut surface of the second vertical member 32 in the upper part 1U. That is, the left-right reversal step and the joining step satisfy the condition (2) of the above two conditions.

[0034] Next, as shown in FIG. 6(a), the wall panel 1 after the height adjustment is turned upside down (upside down turning step). Next, the reinforcing material 4 that has been temporarily fixed to the horizontal material 2 by staples or the like is removed from the horizontal material 2. Then, as shown in Fig. 6(b), the reinforcing material 4 is bridged between adjacent vertical materials 3 and fixed by fasteners (screws or the like), adhesive, or a combination of these (full fixing step). The full fixing step may be performed before the upside-down turning step. In this embodiment, as shown in FIG. 4(b), the height dimension of the lower portion 1D (the side where the reinforcing material 4 is temporarily fixed to the horizontal member 2) is longer than the height dimension of the upper portion 1U (the side where the reinforcing material 4 is not temporarily fixed to the horizontal member 2). This makes it easier to remove the temporarily fixed reinforcing material 4. That is, in this embodiment, the height dimension of the lower portion 1D is set longer than the height dimension of the upper portion 1U so that the upper portion 1U does not get in the way when removing the temporarily fixed reinforcing material 4 after the joining step.

[0035] Next, as shown in FIG. 7, the wall panel 1 after the height adjustment is installed (installation step). Specifically, as shown in FIG. 7(a), of two types of wall panels 1 (wall panels 1 after height adjustment) that have the same height but different widths (horizontal length), one wall panel 1 (the wall panel 1 with the longer width) is installed adjacent to the wall panel W that constitutes the wall separating the kitchen and dining area. The wall panel 1 and the wall panel W are installed so that their front faces (the faces facing the kitchen counter K) are substantially flush with each other. Since the wall panel 1 satisfies the above two conditions, both the top and bottom ends of the side face of the wall panel 1 (the side facing the wall panel W) are directly fixed to the wall panel W using fasteners (screws, etc.), adhesive, or a combination of these. The thicknesses (lengths perpendicular to both the horizontal and vertical directions) of the wall panel 1 and the wall panel W adjacent to the wall panel 1 are set to be substantially the same.

[0036] Then, as shown in Figure 7(b), of two types of wall panels 1 (wall panels 1 after height adjustment) that have the same height but different widths (horizontal length), the other wall panel 1 (the wall panel 1 with the shorter width) is installed adjacent to one wall panel 1. At this time, the other wall panel 1 is installed so that its rear surface (the surface opposite the kitchen counter K) is approximately flush with the side surface of one wall panel 1 (the side opposite the wall panel W). Because the other wall panel 1 satisfies the above two conditions, both the top and bottom ends of the side surface of the other wall panel 1 (the side surface on the side of one wall panel 1) are directly fixed to one wall panel 1 by fasteners (screws, etc.), adhesive, or a combination of these.

[0037] Next, as shown in Figure 8(a), a receiving material (rough siding) 5 for receiving the fire-resistant surface material R to be attached to the wall panel 1 is fixed to the vertical member 3 of one of the multiple vertical members 3 in one wall panel 1 that faces the other wall panel 1 using fixing devices (screws, etc.), adhesive, or a combination of these (installation step). Next, as shown in Fig. 8(b), one wall panel 1 and the other wall panel 1 are covered with a fire-resistant surface material R (covering step). In this embodiment, gypsum board is used as the fire-resistant surface material (fire-resistant covering material) R, but the present invention is not limited to this.

[0038] In the examples shown in Figures 4 to 9, as shown in Figures 7(b) and 8(a), of the two wall panels 1 that are perpendicular to each other in an L-shape when viewed from above, one wall panel 1 (the wall panel 1 adjacent to wall panel W) is the winning wall in terms of fit, and the other wall panel 1 is the losing wall. As shown in Figure 7(b), in the recessed corner formed by one wall panel 1 and the other wall panel 1, the vertical member 3 of the other wall panel 1 on the losing side (the vertical member 3 on the one wall panel 1 side) is exposed, and therefore the vertical member 3 can come into contact with the fire-resistant surface material R covering the front surface (the surface on the kitchen counter K side) of the wall panel 1. Therefore, a fastener for fixing the fire-resistant surface material R covering the front surface (the surface on the kitchen counter K side) of the wall panel 1 can be driven toward the vertical member 3. In contrast, the vertical member 3 of one wall panel 1, which is the winning side (the vertical member 3 on the other wall panel 1 side), is hidden behind the other wall panel 1 and is not exposed, so the vertical member 3 cannot come into contact with the fire-resistant surface material R covering the front surface (the surface on the kitchen counter K side) of the wall panel 1. Therefore, it is not possible to drive a fixing tool for fixing the fire-resistant surface material R covering the front surface (the surface on the kitchen counter K side) of the wall panel 1 toward the vertical member 3.

[0039] That is, the fixed portions in the inside corner (portions into which fasteners for fastening the fire-resistant facing material R are driven) in the losing-side wall panel 1 (the other wall panel 1) are the upper and lower horizontal members 2, the reinforcing members 4 (the reinforcing members 4 on one wall panel 1 side), and the vertical members 3 (the vertical members 3 on one wall panel 1 side), whereas in the winning-side wall panel 1 (one wall panel 1), the fixed portions are the upper and lower horizontal members 2 and the reinforcing members 4 (the reinforcing members 4 on the other wall panel 1 side), and the vertical members 3 (the vertical members 3 on the other wall panel 1 side) cannot be fixed portions. Therefore, in the winning-side wall panel 1, there is no fixed portion in the inside corner between the reinforcing members 4 and the horizontal members 2. Therefore, in this embodiment, in order to provide a fixed portion in the inside corner between the reinforcing members 4 and the horizontal members 2 on the winning-side wall panel 1, the attachment step ( FIG. 8( a) ) is performed, and the receiving member 5 is fixed in a position that allows it to come into contact with the fire-resistant facing material R covering the front surface (the surface on the kitchen counter K side) of the winning-side wall panel 1. This allows fasteners for fixing the fire-resistant surface material R to be driven between the reinforcing material 4 and the horizontal member 2 in the winning wall panel 1, making it possible to maintain a more stable fixed state of the fire-resistant surface material R relative to the winning wall panel 1.

[0040] In the example shown in Figure 8(a), the receiving material 5 is attached between the reinforcing material 4 and the lower cross member 2 (the cross member 2 between the upper and lower cross members 2 that has a longer distance from the reinforcing material 4), but this is not limited to this, and the receiving material 5 may be attached both between the reinforcing material 4 and the lower cross member 2 and between the reinforcing material 4 and the upper cross member 2. 4 to 9, one wall panel 1 (the wall panel 1 adjacent to the wall panel W) is set as the winning side and the other wall panel 1 is set as the losing side, but the opposite is also possible. That is, one wall panel 1 (the wall panel 1 adjacent to the wall panel W) may be set as the losing side and the other wall panel 1 may be set as the winning side, in which case, in the mounting step, the receiving member 5 is fixed to the vertical member 3 facing the one wall panel 1 out of the multiple vertical members 3 of the other wall panel 1.

[0041] Next, as shown in Figure 9(a), the wall panel 1 covered with the fire-resistant surface material R is covered with finishing materials such as wallpaper 11, a coping board 12, and a counter board 13 (finishing step). This results in the formation of a spandrel wall 10 that is L-shaped in plan view. 9(b), the kitchen table K is installed so that a corner of the kitchen table K (one of the corners on the dining room side) fits into the recessed corner of the waist wall 10.

[0042] The lower end of the kitchen counter K is fixed with screws to the lower horizontal member 2 of the wall panel 1. Also, the upper end of the kitchen counter K is fixed with screws to a reinforcing member (filler for fixing the lower counter) 4 of the wall panel 1. That is, in the example shown in Figures 4 to 9, the fixing position of the reinforcing member 4 (the position when the reinforcing member 4 is fixed between the vertical members 3) is set to a position corresponding to the upper end of the kitchen counter K. Furthermore, in the example shown in Figures 4 to 9, an upside-down inversion step (Figure 6(a)) is performed to fix (fully fix) the reinforcing member 4 at a position corresponding to the upper end of the kitchen counter K without adjusting the length dimension (length in the left-right direction) of the reinforcing member 4 temporarily fixed to the horizontal member 2.

[0043] At the joint between the upper portion 1U and the lower portion 1D, the spacing between the vertical members 3 is shortened, so in order to permanently fix the reinforcing members 4 temporarily fixed to the horizontal members 2 to the joint, it is necessary to adjust (shorten) the length of the reinforcing members 4. In contrast, at the other parts of the joint between the upper portion 1U and the lower portion 1D, the spacing between the vertical members 3 does not change (it does not change before and after adjusting the height of the wall panel 1). Therefore, when permanently fixing the reinforcing members 4 temporarily fixed to the horizontal members 2 to parts other than the joint, it is not necessary to adjust the length of the reinforcing members 4. Therefore, in this embodiment, in order to reduce the number of work processes, the reinforcing members 4 temporarily fixed to the horizontal members 2 are permanently fixed to parts other than the joint (see FIG. 6(b)). Furthermore, as mentioned above, in this embodiment, the height dimension of the lower portion 1D (the side where the reinforcement material 4 is temporarily fixed to the cross member 2) is set to be longer than the height dimension of the upper portion 1U (the side where the reinforcement material 4 is not temporarily fixed to the cross member 2) so that the upper portion 1U does not get in the way when removing the reinforcement material 4 that has been temporarily fixed after the joining step.

[0044] In this embodiment, an upside-down step (Figure 6(a)) is performed to satisfy the following three conditions: (a) the fixing position of the reinforcing material 4 is set at a position corresponding to the upper end of the kitchen counter K; (b) the reinforcing material 4 is permanently fixed to a position other than the joint portion; and (c) the height dimension of the lower portion 1D (the side where the reinforcing material 4 is temporarily fixed to the cross member 2) is set to be longer than the height dimension of the upper portion 1U (the side where the reinforcing material 4 is not temporarily fixed to the cross member 2). Therefore, if it is not necessary to satisfy condition (a) among conditions (a) to (c), for example, if the fixed position of the reinforcement material 4 is set to the vertical center of the wall panel 1 after height adjustment or below the vertical center, there is no need to perform the up-down inversion step.

[0045] Furthermore, if it is not necessary to satisfy condition (b) among conditions (a) to (c), for example, if the length dimension of the reinforcing material 4 temporarily fixed to the horizontal material 2 is adjusted at the construction site, or if the reinforcing material 4 is not temporarily fixed to the horizontal material 2 and is prepared at the construction site (if work such as cutting the square timber to a length that matches the spacing dimension between the vertical materials 3 is performed at the construction site), then the upside-down inversion step does not need to be performed. Furthermore, if it is not necessary to satisfy condition [c] among conditions [a] to [c], for example, if the reinforcing material 4 is not temporarily fixed to the horizontal material 2 and the reinforcing material 4 is prepared at the construction site (if work such as cutting a square timber to a length that matches the spacing dimension between the vertical materials 3 is done at the construction site), or if the height dimension of the lower part 1D (the side where the reinforcing material 4 is temporarily fixed to the horizontal material 2) is not set longer than the height dimension of the upper part 1U (the side where the reinforcing material 4 is not temporarily fixed to the horizontal material 2) (if it is set shorter or approximately the same), then there is no need to perform the upside-down inversion step. That is, the upside-down step is not an essential step.

[0046] The mounting step is also not a required process. In other words, since the mounting step is a step for mounting the receiving material 5 to the wall panel 1 that is the winning side in terms of fit, if there is no winning or losing in the fit of the wall panel 1, specifically, for example, in the case of a waist wall that is I-shaped in plan view (when the waist wall is made up of only one wall panel 1, or when the waist wall is made up of multiple wall panels 1 lined up in a straight line), the mounting step does not need to be performed.

[0047] In this embodiment, the thickness dimension (length in the direction perpendicular to both the horizontal and vertical directions) of the reinforcing material 4 is set to approximately half the thickness dimension (length in the direction perpendicular to both the horizontal and vertical directions) of the horizontal material 2, but is not limited to this. For example, the thickness of the reinforcing material 4 may be set to be substantially the same as the thickness of the wall panel 1, as shown in FIG. 10(a). Also, as shown in FIG. 10(a), it is possible to install a cabinet 20 or the like on the rear surface of one wall panel 1 (the surface opposite to the kitchen table K).

[0048] In this embodiment, the thickness of the wall panel 1 is the same as the thickness of the horizontal member 2 and the vertical member 3. Therefore, by setting the thickness of the reinforcing member 4 to be approximately the same as the thickness of the wall panel 1, for example, as shown in Fig. 10(a), when installing equipment and furniture (such as a kitchen counter K or a cabinet 20) on both sides (front and rear) of the wall panel 1, screws of the same length as those used to install the equipment and furniture on the front side of the wall panel 1 to the reinforcing member 4 can be used, and screws of the same length as those used to install the equipment and furniture on the rear side of the wall panel 1 to the reinforcing member 4 can be used, which has the advantage of making the installation of the equipment and furniture easier than when screws of various lengths must be prepared for installing the equipment and furniture.

[0049] Further, for example, reinforcing members 4 (for example, reinforcing members 4 having a thickness about half that of the horizontal members 2) may be temporarily fixed to both the upper and lower horizontal members 2. In this case, as shown in Fig. 10(b), for example, the reinforcing member 4 temporarily fixed to one of the upper and lower horizontal members 2 may be permanently fixed at a position that will serve as a base for fixing equipment or furniture to be installed on the front side of the wall panel 1 (a kitchen counter K in the example shown in Fig. 10(b)), and the reinforcing member 4 temporarily fixed to the other of the upper and lower horizontal members 2 may be permanently fixed at a position that will serve as a base for fixing equipment or furniture to be installed on the rear side of the wall panel 1 (a cabinet 20 in the example shown in Fig. 10(b)).

[0050] 4 to 9, the portion of the waist wall 10 that is aligned in a straight line with the wall separating the kitchen from the dining room (the wall formed by the wall panel W) is formed by one wall panel 1, but this is not limited to this. For example, as shown in Fig. 11, the portion of the waist wall 10 that is aligned in a straight line with the wall separating the kitchen from the dining room (the wall formed by the wall panel W) can also be formed by multiple wall panels 1.

[0051] 4 to 9, a wall is constructed using wall panels 1 after height adjustment, but the present invention is not limited to this, and it is also possible to construct a wall using wall panels 1 before height adjustment as they are without adjusting their height. When using wall panels 1 before height adjustment as they are, it is preferable to perform a permanent fixing step in which the temporarily fixed reinforcing members 4 are removed from the horizontal members 2, and the reinforcing members 4 are placed between adjacent vertical members 3 while being spaced apart from both the upper horizontal member 2 and the lower horizontal member 2, and fixed (permanently fixed) using fixing devices (screws, etc.), adhesive, or a combination of these, as shown in FIG.

[0052] Furthermore, the reinforcing members 4 do not have to be temporarily fixed to the horizontal members 2. The reason for temporarily fixing the reinforcing members 4 to the horizontal members 2 is to prepare reinforcing members 4 of a length that matches the spacing dimension between the vertical members 3 in the factory, and to transport the prepared reinforcing members 4 to the construction site together with the wall panel 1 in a state where they correspond to the corresponding positions. As mentioned above, it is possible to prepare the reinforcing material 4 at the construction site, but in that case, more work must be done at the construction site, such as cutting the square timber to a length that matches the spacing dimensions between the vertical members 3. It is also possible to prepare the reinforcing members 4 in a factory and transport them to the construction site separately from the wall panels 1. However, when the spacing dimensions between the vertical members 3 are not uniform, as in the wall panels 1 of this embodiment (wall panels 1 before height adjustment), transporting the reinforcing members 4 and the wall panels 1 separately increases the amount of work that must be done at the construction site, such as the task of finding reinforcing members 4 that fit the spacing dimensions between the vertical members 3 from among multiple reinforcing members 4 with different length dimensions. That is, in this embodiment, in order to minimize the amount of work that must be done at the construction site, the reinforcing member 4 is temporarily fixed to the horizontal member 2. Therefore, temporarily fixing the reinforcing member 4 is not an essential configuration.

[0053] Furthermore, as shown in FIG. 13(a), the horizontal member 2 does not necessarily have to be provided with the protruding portion 2a. Furthermore, if the horizontal member 2 does not have a protruding portion 2a, the left-right reversal step before the joining step does not need to be performed, as shown in FIG. 13(b). Furthermore, when the horizontal member 2 does not have the protruding portion 2a, an adjusting member 6 having a width dimension substantially the same as the width dimension of the vertical member 3 may be fixed to the end face of the horizontal member 2. In other words, the protruding portion 2a may be attached later.

[0054] Specifically, for example, as shown in Figure 13(b), when performing a joining step to join the right side of each vertical member 3 in the upper part 1U and the left side of each vertical member 3 in the lower part 1D without performing a left-right reversal step, an adjustment member 6 having a width dimension (length in the left-right direction) approximately the same as the width dimension of the second vertical member 32 may be fixed to the right end face of the horizontal member 2 in the upper part 1U, and an adjustment member 6 having a width dimension (length in the left-right direction) approximately the same as the width dimension of the first vertical member 31 may be fixed to the left end face of the horizontal member 2 in the lower part 1D. Furthermore, when a joining step is performed to join the left side of each vertical member 3 in the upper part 1U with the right side of each vertical member 3 in the lower part 1D without performing the left-right reversal step, an adjustment member 6 having a width dimension (length in the left-right direction) approximately the same as the width dimension of the first vertical member 31 may be fixed to the left end face of the horizontal member 2 in the upper part 1U, and an adjustment member 6 having a width dimension (length in the left-right direction) approximately the same as the width dimension of the second vertical member 32 may be fixed to the right end face of the horizontal member 2 in the lower part 1D. In the example shown in FIG. 13(b), the height dimension (vertical length) of the adjustment member 6 is set to be approximately the same as the height dimension (vertical length) of the cross member 2, but is not limited to this.

[0055] <Effects> According to this embodiment, the following excellent effects are achieved. The wall panel 1 of this embodiment is a wall panel that constitutes a wall of a building (for example, a waist wall 10), and comprises a pair of horizontal members 2 facing each other and a plurality of vertical members 3 arranged between the pair of horizontal members 2. The wall panel 1 can be divided vertically (in the extension direction of the vertical members 3) into an upper portion 1U and a lower portion 1D, and installed in a joined state with the side surfaces of the vertical members 3 in the upper portion 1U and the vertical members 3 in the lower portion 1D joined together.

[0056] Therefore, the wall panel 1 of this embodiment can be divided into an upper part 1U and a lower part 1D, and the height dimension can be adjusted (shortened) simply by joining the sides of the vertical member 3 in the upper part 1U and the vertical member 3 in the lower part 1D, so that the height can be adjusted at the construction site. Furthermore, the wall panel 1 of this embodiment does not have a face material, making wiring and piping easy. In other words, the process that would be necessary to have a face material (for example, the process of forming holes in the face material for wiring and piping) can be omitted, making wiring and piping easy. The wall formed by the wall panels 1 (the wall panel 1 before the height adjustment and the wall panel 1 after the height adjustment) is not limited to a waist wall, but may be a partition wall, a vertical wall, or the like.

[0057] In the wall panel 1 of this embodiment, the plurality of vertical members 3 include a first vertical member 31 located furthest on one side in the horizontal direction (extension direction of the horizontal members 2) and a second vertical member 32 located furthest on the other side in the horizontal direction, and the horizontal member 2 has a protruding portion 2a that protrudes to one side beyond the first vertical member 31, and the protruding dimension of the protruding portion 2a is set to be approximately the same as the width dimension of the second vertical member 32, and in the joined state, the protruding portion 2a of the horizontal member 2 in the upper portion 1U faces the cut surface of the second vertical member 32 in the lower portion 1D, and the protruding portion 2a of the horizontal member 2 in the lower portion 1D faces the cut surface of the second vertical member 32 in the upper portion 1U.

[0058] Therefore, in the wall panel 1 of this embodiment, both the wall panel 1 before the height adjustment and the wall panel 1 after the height adjustment can be fixed directly to the wall (wall panel) adjacent to the wall panel 1 at both the upper and lower ends of the side of the wall panel 1, making the installation easier than when the protrusion 2a is added later, for example, as shown in Figure 13. The wall panel 1 does not have to have the protrusion 2a, for example, as shown in FIG.

[0059] The construction method of this embodiment is a construction method for a wall (for example, a waist wall 10) that includes a wall panel 1, and includes a determination step of determining cutting positions based on the design dimensions of the wall, a cutting step of cutting the wall panel 1 at the cutting positions determined in the determination step to divide it into an upper portion 1U and a lower portion 1D, and a joining step of joining the upper portion 1U and the lower portion 1D, wherein the wall panel 1 comprises a pair of horizontal members 2 facing each other and a plurality of vertical members 3 provided between the pair of horizontal members 2, and in the joining step, the side surfaces of the vertical members 3 in the upper portion 1U and the vertical members 3 in the lower portion 1D are joined together.

[0060] Therefore, according to the construction method of this embodiment, the height dimension of the wall panel 1 can be adjusted (shortened) simply by dividing the wall panel 1 into an upper part 1U and a lower part 1D and joining the sides of the vertical members 3 in the upper part 1U and the vertical members 3 in the lower part 1D, so that the height dimension of the wall panel 1 can be adjusted (shortened) at the construction site. Furthermore, the wall panel 1 used in the construction method of this embodiment does not have a face material, making wiring and piping easy. In other words, the process that would be necessary to have a face material (for example, the process of forming holes in the face material for wiring and piping) can be omitted, making wiring and piping easy.

[0061] In the construction method of this embodiment, the plurality of vertical members 3 include a first vertical member 31 located at the furthest side in the horizontal direction (extension direction of the horizontal members 2) and a second vertical member 32 located at the furthest side in the horizontal direction, and the horizontal member 2 has a protruding portion 2a that protrudes to one side beyond the first vertical member 31, and the protruding dimension of the protruding portion 2a is set to be approximately the same as the width dimension of the second vertical member 32. In the joining step, the first vertical member 31 in the upper portion 1U and the second vertical member 32 in the lower portion 1D are joined, and The method includes an inversion step (left-right inversion step) of inverting one of the upper part 1U and the lower part 1D so that the first vertical member 31 in the upper part 1U and the second vertical member 32 in the lower part 1D are joined, and in the joining step, the upper part 1U and the lower part 1D are joined in a state in which the protruding portion 2a of the horizontal member 2 in the upper part 1U faces the cut surface of the second vertical member 32 in the lower part 1D, and the protruding portion 2a of the horizontal member 2 in the lower part 1D faces the cut surface of the second vertical member 32 in the upper part 1U.

[0062] Therefore, according to the construction method of this embodiment, both the wall panel 1 before the height adjustment and the wall panel 1 after the height adjustment can be fixed directly at both the upper and lower ends of the side of the wall panel 1 to the wall (wall panel) adjacent to the wall panel 1, so that the installation work is easier than when the protrusion 2a is added later, for example, as shown in Figure 13.

[0063] In addition, in the construction method of this embodiment, a reinforcing material 4 is temporarily fixed to the horizontal material 2, and a final fixing step is included in which the reinforcing material 4 is removed from the horizontal material 2 and bridged between adjacent vertical materials 3 and fixed therein.

[0064] Therefore, a reinforcing material 4 can be provided on the wall panel 1, which functions as an auxiliary crosspiece (horizontal crosspiece) and also as a fixing base when fixing equipment and furniture (such as a kitchen counter K or cabinet 20) to a wall formed by the wall panel 1. Furthermore, the wall panel 1 with the reinforcing members 4 temporarily fixed to the cross members 2 can be transported from the factory to the construction site, and the reinforcing members 4 can be fixed (permanently fixed) at the construction site in a position that takes into consideration the height dimension of the wall panel 1 after adjustment and the height dimension of equipment and furniture to be fixed to the wall formed by the wall panel 1, making it easy to use.

[0065] Furthermore, the construction method of this embodiment includes a covering step of covering the wall panel 1 with the fire-resistant facing material R, an attachment step of fixing the receiving material 5 for receiving the fire-resistant facing material R to the vertical member 3, and an installation step of installing the wall panel 1. In the installation step, multiple wall panels 1 are installed so as to be perpendicular to each other, and in the attachment step, the receiving material 5 is attached to the recessed corner formed by the wall panels 1 that are perpendicular to each other.

[0066] Therefore, even if the vertical member 3 of one of two perpendicular wall panels 1 is hidden by the other wall panel 1 and the vertical member 3 cannot be used as a fixed portion (a portion into which a fixing tool for fixing the fire-resistant surface material R is driven), by attaching the receiving member 5 to the vertical member 3, a fixed portion can be provided near the vertical member 3, making it possible to maintain a more stable fixed state of the fire-resistant surface material R to the wall panel 1.

[0067] The wall panel 1 of this embodiment is a wood panel. In recent years, there has been a demand for the realization of a carbon-neutral society by promoting carbon neutrality, which reduces carbon dioxide emissions to virtually zero, and for the achievement of the SDGs (Sustainable Development Goals), and in the construction industry, efforts are being made to build buildings using wood, which has low carbon dioxide emissions.A building constructed using the wall panel 1 of this embodiment can be partially or entirely (at least the walls) made of wood, which can contribute to the realization of a carbon-neutral society by promoting carbon neutrality and the achievement of the SDGs.
