For convenience, in the following description, the case where the first floor portion pillar 6A and the second floor portion pillar 6B are not distinguished is called the pillar 6, and the case where the first floor portion earthquake resistant panel 7A and the second floor portion earthquake resistant panel 7B are not distinguished. It is called earthquake-resistant panel 7.

Of the members constituting the wooden building 1, the earthquake-resistant panel 7 is a kind of wall panel, which is wooden and has a rectangular shape in front view. Note that the rectangle in this specification includes a square having four equal sides. The base 4, the column 6, the beam 8, and the eaves girder 11 are a kind of frame members, are made of wood, and are arranged along each edge of the earthquake-resistant panel 7. A groove 12 is provided on a surface of the base 4, the column 6, the beam 8, and the eaves girder 11 facing the edge of the earthquake resistant panel 7, and the groove 12 has an edge of the structural plywood 16 included in the earthquake resistant panel 7. 16a (see FIG. 3) is inserted. Although details will be described later, a filler 19 (see FIG. 5B) is filled between the inner surface of the groove 12 and the edge 16a of the structural plywood 16.
In addition, the outdoor surface of the earthquake-resistant panel 7 is covered with an outer wall panel 13 (a kind of heat insulating panel) having heat insulation properties, and the outdoor surface of the outer wall panel 13 has heat insulation properties and water shielding properties. The outer wall material 14 is covered. As shown in FIG. 2, the interior surface of the earthquake-resistant panel 7 is covered with a heat-insulating inner wall panel 15 (a kind of heat-insulating panel). 15 is omitted.

<Wall structure of wooden building 1>
FIG. 2 is a view for explaining the wall structure of the wooden building 1, and FIGS. 3A to 3C are a front view, a rear view, and a side view of the earthquake-resistant panel 7C.
As shown in FIG. 2, the earthquake-resistant panel 7 uses a plurality of types of earthquake-resistant panels 7C and 7D having different lateral widths. In the present embodiment, a standard-width seismic panel 7C having a lateral width of, for example, 845 mm, and a wide seismic panel 7D having a lateral width of, for example, 1755 mm are used. In addition, all the earthquake-resistant panels 7C and 7D have the same height, for example, 2730 mm.
As shown in FIG. 3, the standard-width seismic panel 7C includes a rectangular structural plywood 16 and a stud 17 joined to the indoor surface of the structural plywood 16 along the longitudinal direction of the structural plywood 16. And a warp stopper 18 joined to the outdoor surface of the structural plywood 16 along the lateral direction of the structural plywood 16.
The structural plywood 16 is obtained by laminating and bonding three or more wood boards with the fiber directions being substantially perpendicular to each other, and conforming to Japanese Agricultural Standards. The structural plywood 16 used for the standard-width seismic panel 7C is, for example, a rectangle whose height in the vertical direction is larger than the width in the horizontal direction, and has a height of 2730 mm, a width of 845 mm, and a thickness of 9 mm. However, it is not limited to this dimension.

The inter-column 17 is a prismatic material that suppresses the vertical deflection in the structural plywood 16. For example, the cross-sectional dimension is 48 mm × 45 mm and the length is 2690 mm. The inter-column 17 is disposed at the lateral center of the structural plywood 16, the upper end edge of the inter-column 17 is disposed below the upper end edge of the structural plywood 16, and the lower end edge of the inter-column 17 is the lower end edge of the structural plywood 16. It is arranged above. For example, the upper end edge of the inter-column 17 is disposed 20 mm below the upper end edge of the structural plywood 16, and the lower end edge of the inter-column 17 is disposed 20 mm above the lower end edge of the structural plywood 16.
The warp stopper 18 is a prismatic material that suppresses lateral deflection in the structural plywood 16, and for example, a laminated material having a cross-sectional dimension of 48 mm × 50 mm and a length of 805 mm is used. A plurality of warpage stoppers 18 are arranged at predetermined intervals in the height direction of the structural plywood 16. In the illustrated earthquake-resistant panel 7C, five warp stoppers 18 are arranged at equal intervals in the height direction. Specifically, one warp stopper 18 is disposed at an intermediate position in the height direction of the structural plywood 16, and two warpage stoppers 18 are arranged at equal intervals above the intermediate position warp stopper 18. Two warp stops 18 are arranged at equal intervals below the intermediate position warp stop 18. And the space | interval of the curvature stopper 18 adjacent to a vertical direction is 441 mm, for example. Note that the warp stopper 18 disposed at the intermediate position in the height direction may be thicker than the other warp stoppers 18. For example, a laminated material having a cross-sectional dimension of 48 mm × 100 mm may be used.
Further, the left end edge of each warp stop 18 is disposed on the right side of the left end edge of the structural plywood 16, and the right end edge of each warp stop 18 is disposed on the left side of the right end edge of the structural plywood 16. For example, the left end edge of each warp stop 18 is disposed 20 mm to the right of the left end edge of the structural plywood 16, and the right end edge of each warp stop 18 is disposed 20 m to the left of the right end edge of the structural plywood 16. Therefore, the spacer 17 and the warp stopper 18 are not arranged on the end edges (upper edge, lower edge, left edge, right edge) 16a of the structural plywood 16.

  The wide earthquake-resistant panel 7D shown in FIG. 2 includes a structural plywood 16, a spacer 17, and a warp stopper 18, as in the case of the standard-width earthquake-resistant panel 7C. The wide earthquake-resistant panel 7D is different in that the width in the horizontal direction is wider than that of the standard-width earthquake-resistant panel 7C and the number of the studs 17 is increased. The structural plywood 16 provided in the wide earthquake-resistant panel 7D has, for example, a height of 2730 mm, a width of 1755 mm, and a thickness of 9 mm. Further, for example, three studs 17 are arranged at equal intervals (for example, at intervals of 455 mm) on the wide earthquake-resistant panel 7D. In the illustrated earthquake-resistant panel 7D, two of the three columns 17 positioned on the left side and the right side have the same dimensions as the column 17 used in the standard-width earthquake-resistant panel 7C (for example, 48 mm × 45 mm × 2), and the single pillar 17 located in the center is wider (for example, 48 mm × 52.4 mm × 2690 mm) than the stud 17 used in the standard width earthquake-resistant panel 7C. Even in the wide earthquake-resistant panel 7 </ b> D, the spacer 17 and the warp stopper 18 are not arranged on the edge 16 a of the structural plywood 16.

<Regarding the groove 12 of the first embodiment>
4A is a perspective view of the tenon 6a provided at the end of the column 6, FIG. 4B is a cross-sectional view of the column 6, and FIG. 4C is a cross-sectional shape of the groove 12 provided in the column 6. FIG.
As shown in FIG. 4A, a tenon 6 a is provided at the end of the column 6. 4A shows the tenon 6a provided at one end of the column 6. However, the tenon 6a is provided at both ends of the column 6. FIG. The tenon 6a is inserted into a tenon (not shown) provided in the base 4, the beam 8, and the eaves girder 11 when the column 6 is erected. Grooves 12 are formed on each side surface of the pillar 6 along the longitudinal direction (axial direction) of the pillar 6. The corresponding edge 16a of the structural plywood 16 provided in the earthquake resistant panel 7 is inserted into the groove 12.
As illustrated in FIG. 4C, the groove 12 is a dovetail. Therefore, the groove width of the inner back portion of the groove 12 is wider than the width W12U of the opening peripheral edge and becomes wider toward the back than the opening peripheral edge. The dimension of each part of the groove 12 is determined according to the dimension of the edge 16a of the structural plywood 16. For example, since the thickness of the structural plywood 16 is, for example, 9 mm, the width W12U of the opening periphery in the groove 12 is set to 10 mm, which is 1 mm wider than the thickness of the structural plywood 16, for example. Further, since a range of 20 mm is inserted into the groove 12 from the end edge of the structural plywood 16, the depth D12 of the groove 12 is, for example, larger than the insertion length of the structural plywood 16 (the width of the edge 16a). It is set to 21 mm which is 1 mm larger. Moreover, the groove width W12B in the innermost part (bottom surface) of the groove | channel 12 is defined, for example as 14 mm.

FIG. 5A is a partial enlarged cross-sectional view of the column 6 and the peripheral portion when two earthquake-resistant panels 7 are connected to the column 6 at an angle of 90 degrees, and FIG. 5B is the column 6 and the earthquake-resistant panel 7. It is a partial expanded sectional view of a connection part.
As shown in FIG. 5 (a), two seismic panels 7 are attached to the pillar 6 located at the corner of the wooden building 1 at an angle of 90 degrees. Accordingly, grooves 12 are formed in two corresponding surfaces of the pillar 6, and the edge 16 a of the structural plywood 16 is inserted into each groove 12.
As shown in FIG. 5B, the edge 16a of the structural plywood 16 inserted into the groove 12 is positioned in front of the innermost surface of the groove 12 with respect to the depth direction with respect to the innermost surface of the groove 12. A filler 19 is filled between the end edge 16a of the structural plywood 16. As the filler 19, a resin having airtightness, liquid tightness, and elasticity is used. For example, a silicon resin or a urethane resin is preferably used.
By filling the inner part of the groove 12 with the filler 19, the end edge 16 a of the structural plywood 16 is covered with the filler 19 without directly contacting the inner surface of the groove 12. Retained. Further, a part of the filler 19 overflows outside the opening of the groove 12 and is hardened. The overflowing filler 19 spreads on the side surface of the column 6 beyond the opening periphery of the groove 12.

6 (a) to 6 (c) are cross-sectional views of the column 6, FIG. 6 (d) is a cross-sectional view of the beam 8, FIG. 6 (e) is a cross-sectional view of the eaves girder 11, and FIG. It is a cross-sectional view of the base 4.
With respect to the pillar 6, in addition to the four surfaces described with reference to FIG. 4, the grooves 12 are formed on each of the four surfaces, and the grooves 12 are provided on each of the three surfaces shown in FIG. As shown in FIG. 6C, a groove 12 is provided on two adjacent surfaces as shown in FIG. 6C, and a groove 12 is provided on two parallel surfaces as appropriate.
As for the beam 8, as shown in FIG. 6 (d), a groove 12 is provided on each of the upper surface and the lower surface. As for the eaves girder 11, a groove 12 is provided on the lower surface as shown in FIG. As for the base 4, a groove 12 is provided on the upper surface as shown in FIG.

<Effects of wall structure>
As described with reference to FIGS. 2 and 3, in the wall structure of the present embodiment, the earthquake-resistant panel 7 (7 </ b> C, 7 </ b> D) is disposed on the surface of the rectangular structural plywood 16 and the structural plywood 16. The warp joined along the lateral direction of the structural plywood 16 to the surface (back surface) different from the surface of the structural plywood 16 provided with the studs 17 joined along the vertical direction. Since the stop 18 is provided, it is possible to improve the resistance of the earthquake-resistant panel 7 to vertical and horizontal shaking with respect to the building 1.
In the wall structure described above, as described in FIG. 5B, the edge 16a of the structural plywood 16 is in the groove 12 provided in the frame member (the base 4, the column 6, the beam 8, and the eaves girder 11). Since the filler 19 is filled in the gap between the inner surface of the groove 12 and the edge 16a of the structural plywood 16 inserted in the groove 12, an external force due to an earthquake or the like is applied to the earthquake resistant panel 7. However, the shaking direction of the building 1 can be regulated in the horizontal direction (see FIG. 1), and the inconvenience that the edge 16a of the structural plywood 16 is pulled out from the frame member can be suppressed.
Moreover, since the groove | channel 12 formed in the frame member is a dovetail groove | channel, and the filler 19 is filled in the state which covers the edge 16a of the structural plywood 16, the edge 16a of the structural plywood 16 is used. On the other hand, even if an external force in a direction away from the groove 12 is applied, the filler 19 acts like a wedge, and the inconvenience that the edge 16a of the structural plywood 16 is detached from the groove 12 can be suppressed. In addition, since the edge 16a of the structural plywood 16 is held in the groove 12 in a state of being covered with the filler 19 without directly contacting the inner surface of the groove 12, the edge of the structural plywood 16 is Even if an external force is applied to the inner portion of the groove 12 with respect to 16a, the filler 19 acts as a cushion to relieve the impact applied to the earthquake resistant panel 7.

<Construction procedure for wall structure>
Next, the construction procedure of the wall structure described above will be described. Here, FIG. 7A is a diagram for explaining a state before the first seismic panel 7 is attached, and FIG. 7B is a partially enlarged cross section for explaining a state in which the groove 12 is filled with the filler 19. FIG. FIG. 8 is a diagram illustrating a state in the middle of attaching the first earthquake-resistant panel 7. FIG. 9A is a diagram for explaining a state in which the first seismic panel 7 is attached, and FIG. 9B is a partially enlarged sectional view for explaining the filler 19 filled in the groove 12 of the column 6. is there. FIG. 10 is a diagram for explaining a state in the middle of attaching the second seismic panel 7. FIG. 11 is a diagram for explaining a state in which the second seismic panel 7 is attached. FIG. 12 is a diagram illustrating a state in which the fourth seismic panel 7 is attached. FIG. 13 is a diagram illustrating a state before the beam 8 is attached. FIG. 14 is a diagram illustrating a state where the beam 8 is attached.
The edge of the earthquake-resistant panel 7 corresponds to the edge 16a of the structural plywood 16. Therefore, the left edge, the right edge, the upper edge, and the lower edge of the earthquake resistant panel 7 in the description of the construction procedure are the left edge, the right edge, the upper edge, and the lower edge of the structural plywood 16, respectively.

As shown in FIG. 7A, the pair of pillars 6 are erected on the base 4 prior to attachment of the first seismic panel 7. In the example shown in the figure, the left pillar 6 positioned at the corner of the wooden building 1 is vertically set on the base 4, and the right pillar 6 is set in a state where the upper portion is inclined rightward. As shown in FIG. 7B, each groove 12 in the pair of pillars 6 and the base 4 (specifically, each groove 12 into which each edge of the first seismic panel 7 is inserted) is not cured. The filler 19 is filled in advance. The filling amount of the filler 19 is adjusted so that the filler 19 overflows somewhat from the opening edge of the groove 12 when the edge of the earthquake-resistant panel 7 is inserted.
When the pair of pillars 6 are erected on the base 4, as shown in FIG. 8, the left edge of the first earthquake-resistant panel 7 is the groove 12 of the left pillar 6, and the right edge is the groove 12 of the right pillar 6. Insert into each. If the left and right edges of the first seismic panel 7 are inserted into the grooves 12, the seismic panel 7 is moved downward.
If the seismic panel 7 is moved downward until the lower edge of the seismic panel 7 is inserted into the groove 12 of the base 4, the right column 6 is perpendicular to the base 4 as shown in FIG. Stand up. As a result, as shown in FIG. 9B, the filler 19 covers the edge of the earthquake-resistant panel 7 (the edge 16 a of the structural plywood 16) in each of the grooves 12 of the pair of pillars 6 and the base 4. Filled.

The second seismic panel 7 is attached after the first seismic panel 7. As shown in FIG. 10, the second seismic panel 7 is attached to the right of the first seismic panel 7 in the same procedure as the first seismic panel 7. In FIG. 10, after the right column 6 is erected with the upper portion tilted to the right, the left edge of the second seismic panel 7 is the groove 12 of the left column 6 and the right edge is the right column 6. The state inserted in each groove 12 is shown. The second seismic panel 7 is moved downward from the state shown in FIG. 10, and then the right pillar 6 is vertically set on the base 4 so that the second seismic panel 7 as shown in FIG. Are attached to the pair of pillars 6 and the base 4.
The third and subsequent seismic panels 7 are attached in the same procedure as the first and second seismic panels 7. FIG. 12 shows a state in which four seismic panels 7 are attached. If a plurality of seismic panels 7 constituting a wall structure in a predetermined range are attached, the beam 8 is attached. When the beam 8 is attached, the groove 12 (see FIG. 6D) formed on the lower surface of the beam 8 is filled with a filler 19 before curing. As shown in FIG. 13, after the beam 8 is positioned above the upper end of each column 6, a tenon 6a formed at the upper end of each column 6 is formed on the lower surface of the beam 8, as shown in FIG. While inserting into a mortise (not shown), the upper edge of the earthquake-resistant panel 7 is inserted into a groove 12 formed on the lower surface of the beam 8. As a result, the beam 8 is attached and the filler 19 is filled between the groove 12 formed in the beam 8 and the upper edge of the earthquake-resistant panel 7.
In addition, about the other wall structure in the 1st floor part of the wooden building 1, and the wall structure of the 2nd floor part of the wooden building 1, since it is constructed | assembled in the same procedure, description is abbreviate | omitted.

<Regarding the modified grooves 12A to 12D provided with the equal-width narrow portion 12a>
Next, a modified example of the groove 12 described above will be described. FIG. 15A is a cross-sectional view for explaining the inner surface shape of the groove 12A of the first modified example, and FIG. 15B is a diagram showing a state where the edge 16a of the structural plywood 16 is inserted into the groove 12A of the first modified example. It is a figure explaining the state filled with 19. FIG. FIGS. 16A to 16C are cross-sectional views illustrating the inner surface shapes of the groove 12B of the second modified example to the groove 12D of the fourth modified example.

As shown in FIG. 15 (a), the groove 12A of the first modified example is provided in the inward and rearward directions from the opening periphery, and the equal-width narrow flange 12a having the groove width equal to the width W12U of the opening periphery, and the constant-width narrow flange And a wide width portion 12b that is provided in the inner depth direction than 12a and has a groove width wider than the groove width of the equal-width narrow flange portion 12a. The groove width of the wide width portion 12b becomes wider toward the back of the groove 12A. In the example of FIG. 15A, the width W12U of the peripheral edge of the opening in the groove 12A is 10 mm, the depth (length in the inner depth direction) D12a of the narrow width narrow portion 12a is 8 mm, and the depth (inner depth direction) of the wide width portion 12b. The length D12b is 13 mm, and the innermost groove width W12D of the wide width portion 12b is 14 mm, but is not limited to this dimension.
As shown in FIG. 15 (b), the edge 12a of the structural plywood 16 is inserted into the groove 12A of the first modification, and the gap between the inner surface of the groove 12A and the edge 16a of the structural plywood 16 is filled. Material 19 is filled.
In the wall structure of the wooden building 1 using the groove 12A of the first modification, even if an external force in a direction along the surface of the structural plywood 16 is applied to the earthquake resistant panel 7 due to an earthquake or the like, the edge of the structural plywood 16 16a can be made difficult to come off from the frame member X. For example, even when an external force is applied to the edge 16a of the structural plywood 16 away from the groove 12, the filler 19 filled in the wide width portion 12b acts like a wedge. The inconvenience that the edge 16a is detached from the groove 12 can be suppressed. Further, even when an external force is applied to the edge 16a of the structural plywood 16 in the direction of pushing into the inner back portion of the groove 12, the impact applied to the earthquake resistant panel 7 can be reduced by the filler 19 serving as a cushion. Furthermore, since the equi-width narrow flange portion 12a is provided, a thickness corresponding to the narrow-width narrow portion 12a is secured in the vicinity of the opening of the groove 12 in the frame member X (base 4, column 6, beam 8, and eaves girder 11). It is possible to effectively suppress the breakage of the frame member X.

In the groove 12A of the first modified example, the groove width of the wide width portion 12a becomes wider toward the back of the wide width portion 12a, but is not limited to this shape. For example, in the groove 12B of the second modified example shown in FIG. 16A, the groove width of the wide width portion 12c is wider than the width W12U of the opening peripheral edge of the groove 12B, and is constant in the inward direction of the wide width portion 12c. It is. In the groove 12C of the third modification shown in FIG. 16B, the inner surface of the wide portion 12d is configured by a valley-shaped concave surface that is recessed in a valley shape toward the outer side in the groove width direction. In the groove 12D of the fourth modified example shown in FIG. 16C, the inner surface of the wide width portion 12e is configured by a concave curved surface that is curved outward in the groove width direction.
In the wall structure of the wooden building 1 using the grooves 12A to 12D of the respective modified examples, even if an external force is applied to the end edge 16a of the structural plywood 16 in a direction away from the grooves 12A to 12D, the structural plywood 16 The disadvantage that the edge 16a is detached from the grooves 12A to 12D can be suppressed. Moreover, even if an external force is applied to the edge 16a of the structural plywood 16 in the direction of pushing into the inner depths of the grooves 12A to 12D, the impact applied to the earthquake resistant panel 7 can be reduced.

<Regarding the modified grooves 12E to 12I provided with the narrow narrow portion 12h>
Next, another modification of the groove 12 described above will be described. FIG. 17A is a cross-sectional view for explaining the inner surface shape of the groove 12E of the fifth modified example, and FIG. 17B is a diagram showing the filling material by inserting the edge 16a of the structural plywood 16 into the groove 12E of the fifth modified example. It is a figure explaining the state filled with 19. FIG. 18A to 18D are cross-sectional views illustrating the inner surface shapes of the groove 12F of the sixth modification to the groove 12I of the ninth modification.

As shown in FIG. 17A, the groove 12E of the fifth modified example is provided in the inner and rear direction from the opening periphery, and the narrow width narrow portion 12f having a narrower width than the width W12U of the opening periphery, and the narrow width And a wide portion 12g that is provided inwardly of the portion 12f and has a groove width wider than that of the narrow and narrow flange portion 12f. The groove width in the narrow narrow part 12f becomes constant after becoming narrower toward the back of the narrow narrow part 12f. The groove width of the wide portion 12g becomes wider toward the back of the wide portion 12g. In the example of FIG. 17A, the width W12U of the opening periphery in the groove 12E is 15 mm, the depth (inward and rearward direction length) D12f of the narrow narrow portion 12f is 8 mm, and the narrowest portion in the narrow narrow portion 12f. The groove width W12M is 10 mm, the depth (inner depth direction) D12g of the wide width portion 12g is 13 mm, and the groove width W12D of the innermost surface in the wide width portion 12g is 14 mm. Absent.
As shown in FIG. 17B, the edge 16a of the structural plywood 16 is inserted into the groove 12E of the fifth modified example, and the gap between the inner surface of the groove 12E and the edge 16a of the structural plywood 16 is filled. Material 19 is filled.
In the wall structure of the wooden building 1 using the groove 12E of the fifth modified example, even if an external force in a direction along the surface of the structural plywood 16 is applied to the structural plywood 16 due to an earthquake or the like, the end of the structural plywood 16 The edge 16a can be made difficult to come off from the frame member X. In particular, since the groove 12E of the fifth modification is provided with the narrow and narrow portion 12f, when an external force is applied to the end edge 16a of the structural plywood 16 in the direction of pushing into the inner back portion of the groove 12G, the groove 12E. The filler 19 filled in the vicinity of the opening acts like a wedge, and excessive movement of the earthquake-resistant panel 7 is suppressed. Further, since the width W12U of the opening periphery in the groove 12E can be made wider than that in the first embodiment, the end edge 16a of the structural plywood 16 can be easily inserted into the groove 12E.

The inner surface shape of the groove provided with the narrow narrow portion 12f is not limited to the inner surface shape of the groove 12E of the fifth modification. For example, in the groove 12F of the sixth modified example shown in FIG. 18A, the depth of the narrow narrow portion 12f is shallower than that of the groove 12E of the fifth modified example. The depth is deeper than the groove 12E of the fifth modified example. In the groove 12G of the seventh modified example shown in FIG. 18B, the groove width of the wide width portion 12i is wider than the narrowest groove width in the narrow narrow portion 12f, and is constant in the inward direction of the wide width portion 12i. It is. In the groove 12H of the eighth modified example shown in FIG. 18C, the inner surface of the wide portion 12j is constituted by a valley-shaped concave surface that is recessed in a valley shape toward the outer side in the groove width direction. In the groove 12I of the ninth modified example shown in FIG. 18D, the inner surface of the wide portion 12k is configured by a concave curved surface.
In the wall structure of the wooden building 1 using the grooves 12E to 12I of the respective modified examples, even if an external force in a direction away from the grooves 12E to 12I is applied to the edge 16a of the structural plywood 16, the structural plywood 16 The disadvantage that the edge 16a is detached from the grooves 12E to 12I can be suppressed. Moreover, even if an external force is applied to the edge 16a of the structural plywood 16 in the direction of pushing into the inner depths of the grooves 12E to 12I, the impact applied to the earthquake resistant panel 7 can be reduced.

<Summary of Configuration, Action, and Effect of the Present Invention>
The wall structure of the wooden building 1 according to the first aspect of the present invention includes a wooden rectangular earthquake-resistant panel 7, and is arranged along each edge of the earthquake-resistant panel 7, and the end of each wall is opposed to each edge. A wooden frame member X (base 4, column 6, beam 8, and eaves girder 11) provided with grooves (grooves 12, grooves 4M, grooves 8M) into which edges are inserted, and the earthquake-resistant panel 7 includes: Separate from the rectangular structural plywood 16 and the surface of the structural plywood 16 which is joined along the longitudinal direction of the structural plywood 16 and the surface of the structural plywood 16 provided with the intermediate pillars 17. And a warping stopper 18 joined along the lateral direction of the structural plywood 16 on the surface, and the groove is inserted with the end edge 16a of the structural plywood 16 and is wider than the width of the opening periphery. In addition, at least a part of the groove width of the inner back portion is wide, and the edge 16a of the structural plywood 16 is inserted. In this state, there is a space between the innermost surface of the groove and the edge 16a of the structural plywood 16 facing the innermost surface, and the structural plywood 16 inserted in the groove and the inner surface of the groove. of the gap between the edge 16a, the filling material 19 made of resin is Hama charge having elasticity. In the construction method of the wall structure, after filling the groove 19 with the unfilled filler 19, the edge 16 a of the structural plywood 16 is inserted into the groove by inserting the edge 16 a of the structural plywood 16 into the groove. you to the state to cover.
In the wall structure of the wooden building 1, a stud 17 is joined to the surface of the structural plywood 16 along the longitudinal direction of the structural plywood 16, and along the lateral direction of the structural plywood 16 to another surface of the structural plywood 16. Since the warp stopper 18 is joined, the resistance of the earthquake-resistant panel 7 to external force can be improved.
