AI Technical Summary
Conventional shear wall structures using wood walls and steel brackets experience low initial rigidity due to gaps between drift pins and holes, and the rigidity decreases when drift pins get stuck in wood walls, limiting the full utilization of wood wall performance.
The wood-resistant seismic wall structure incorporates a wood wall member and a wood ramen member, where the end of the wood wall member enters the wood ramen member along the in-plane direction, forming a wood ramen member that efficiently transmits shear forces and additional axial forces to the lower floor.
This configuration enhances the rigidity and strength of the wood shear wall structure, allowing for direct transmission of forces to the center of gravity of the wood members, and facilitates easier construction of beam-column structures with higher integrity.

Description
[Technical field]
[0001] The present invention relates to a wooden shear wall structure, a wooden shear wall unit, and a method for constructing a wooden shear wall unit. [Background technology]
[0002] Conventionally, a seismic wall structure has been known that has a pair of beams arranged above and below, a pair of columns on which the beams are erected, and a single wooden wall provided within the structural plane of the frame made up of the beams and columns (see, for example, Patent Document 1). The wooden wall of this seismic wall structure is made of Cross Laminated Timber (CLT), which is made by laminating and bonding multiple lamina materials so that their fiber directions are perpendicular to each other, and is placed with a gap between it and the pair of beams, and is joined to the pair of beams only by shear force transmission members provided at approximately the center in the width direction.
[0003] The shear force transmission member is composed of a bracket and a drift pin made of a steel material attached to the beam, and a joint plate part extending from the bracket toward the wooden wall is inserted into slits formed in the upper and lower end faces of the wooden wall. The wooden wall is fixed to the joint plate part by a plurality of drift pins that penetrate the wooden wall and the joint plate part in the thickness direction. Also known is a seismic wall in which wooden wall material is provided between the lower beam, upper beam, and left and right columns of a wooden structure (for example, see Patent Document 2). [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Japanese Patent Application Publication No. 2020-101052 [Patent Document 2] Japanese Patent Application Publication No. 2013-147829 Summary of the Invention [Problem to be solved by the invention]
[0005] When beams and wooden walls are joined with steel brackets and drift pins as in the above conventional earthquake-resistant wall structure, the diameter of the hole through which the drift pin penetrates, which is pre-made in the bracket, is larger than the diameter of the drift pin, so there is a problem that the initial rigidity is low due to the gap between the hole and the drift pin. In addition, since the transmission of shear force to the wooden wall is dependent on the drift pin, the drift pin sinks into the wooden wall, reducing the rigidity, and there is a problem that the inherent performance of the wooden wall cannot be fully utilized.
[0006] The present invention has been made in consideration of the above-mentioned problems in the conventional art, and its main object is to provide a wooden shear wall structure, a wooden shear wall unit, and a construction method for a wooden shear wall unit that have higher rigidity and strength by using wooden wall members in a wooden frame. [Means for solving the problem]
[0007] In order to achieve this object, the wooden shear-resistant wall structure of the present invention comprises wooden wall members which constitute a wooden shear-resistant wall, and wooden rigid frame member components which constitute a wooden rigid frame member together with the wooden wall members, the wooden wall members are joined to the wooden rigid frame member components in such a manner that their ends extend into the wooden rigid frame member along the in-plane direction of the wooden wall members, and the length by which the ends of the wooden wall members extend into the wooden rigid frame member is the distance from the outer peripheral surface of the wooden rigid frame member into which the ends of the wooden wall members extend to the center of gravity of the wooden rigid frame member. the wooden rigid frame member is a wooden column, and has a beam supported by the wooden column and arranged in a direction intersecting the wooden wall member; The wooden wall member has a wall member notch portion in which the beam is placed, and the wooden rigid frame member component is arranged on the opposite side of the wooden wall member from the beam and joined to end faces of the beam and the wooden wall member in a state in which the beam is placed in the wall member notch portion of the wooden wall member and the wooden wall member is abutted against the wall member notch portion of the wooden wall member, and the wooden rigid frame member component has a component notch portion in which the beam is placed and is joined to both sides of the end portion of the wooden wall member. It is characterized by:
[0008] In a seismic wall, there is a shear force transmitted from the upper floor walls and floors through the beams, and an additional axial force that occurs when the seismic wall bears the shear force, and it is desirable to transmit these shear forces and additional axial forces to the lower floors more efficiently. Even in the case of conventional seismic walls, where the column beam and wooden wall are joined with gusset plates and drift pins, or where cotters are provided on both and joined by engaging the cotters, since the column beam and wooden wall are separated, it is difficult to fully transmit the allowable shear force of the wooden wall and the additional axial force at that time.
[0009] In the above wooden shear-resistant wall structure, the ends of the wooden wall members are arranged in a state where they penetrate into the wooden rigid frame member along the in-plane direction of the wooden wall member and are joined to the wooden rigid frame member components, thereby forming a wooden rigid frame member together with the wooden rigid frame member components. Therefore, the wooden wall member and the wooden rigid frame member components are integrated to form a wooden rigid frame member, so that the shear force and additional axial force act on the entire wooden wall member and wooden rigid frame member and are transmitted to the lower floor. Therefore, it is possible to provide a wooden shear-resistant wall structure with higher rigidity and strength by using wooden wall members in a wooden frame.
[0010] In addition, the length by which the end of the wooden wall component extends into the wooden rigid frame component is equal to or greater than the length from the outer peripheral surface of the wooden rigid frame component into which the end extends to the center of gravity of the wooden rigid frame component, so that shear force and additional axial force can be transmitted directly to the center of gravity of the wooden rigid frame component. In addition, it is possible to easily form a wooden earthquake-resistant wall that is integrated with the beams and wooden columns that are arranged in a direction that intersects with the wooden wall members, making it possible to easily construct a column-beam structure with higher rigidity and strength.
[0011] In such a wooden earthquake-resistant wall structure, the wooden rigid frame member is characterized in that it is formed by the end of the wooden wall member and a pair of wooden rigid frame member components each joined to the end of the wooden wall member from both sides in the out-of-plane direction of the wooden wall member.
[0012] With this type of wooden earthquake-resistant wall structure, a wooden rigid frame member can be easily formed by simply joining wooden rigid frame member components to the end of the wooden wall member from both sides in the out-of-plane direction of the wooden wall member. It is also easier to form the state in which the end of the wooden wall member is embedded within the wooden rigid frame member, and it is possible to reliably set the length over which the end of the wooden wall member is embedded to be equal to or greater than the length from the outer peripheral surface of the wooden rigid frame member into which the end is embedded to the center of gravity of the wooden rigid frame member.
[0015] The present invention also has wooden wall members which constitute a wooden earthquake-resistant wall, and wooden rigid frame member components which, together with the wooden wall members, constitute a wooden rigid frame member, wherein the wooden wall members are joined to the wooden rigid frame member components in such a manner that their ends extend into the wooden rigid frame member along the in-plane direction of the wooden wall members, and the length over which the ends of the wooden wall members extend into the wooden rigid frame member is equal to or longer than the length from the outer peripheral surface of the wooden rigid frame member into which the ends of the wooden wall members extend to the center of gravity of the wooden rigid frame member, The wooden wall members are comprised of two parallel wooden wall members arranged horizontally to form the same plane, and a cross wooden wall member arranged in a direction intersecting the two parallel wooden wall members, the two parallel wooden wall members being joined at their ends and the ends of the cross wooden wall member being joined together with the ends of the parallel wooden wall members to which the parallel wooden wall members are joined, and the wooden rigid frame member components are comprised of a planar wooden rigid frame member component joined to the surface of the parallel wooden wall members opposite to the side on which the cross wooden wall member is arranged, and an inside corner wooden rigid frame member component joined to each of the inside corners formed by the parallel wooden wall members and the cross wooden wall member.
[0016] In this type of wooden earthquake-resistant wall structure, a wooden earthquake-resistant wall is composed of two wooden wall members that are arranged horizontally side by side to form the same plane, and another wooden earthquake-resistant wall is joined in an upright position, arranged in a direction intersecting the first wooden earthquake-resistant wall, together with the wooden rigid frame member components, and the joint forms a wooden rigid frame member, making it possible to join three wooden wall members in a T-shape with greater rigidity and strength.
[0017] The present invention also has wooden wall members which constitute a wooden earthquake-resistant wall, and wooden rigid frame member components which, together with the wooden wall members, constitute a wooden rigid frame member, wherein the wooden wall members are joined to the wooden rigid frame member components in such a manner that their ends extend into the wooden rigid frame member along the in-plane direction of the wooden wall members, and the length over which the ends of the wooden wall members extend into the wooden rigid frame member is equal to or longer than the length from the outer peripheral surface of the wooden rigid frame member into which the ends of the wooden wall members extend to the center of gravity of the wooden rigid frame member, The structure is characterized in that it has two wooden wall members arranged in a direction intersecting each other and standing to form a corner, and the wooden rigid frame member components are arranged on the inside and outside of the corner and joined to the ends of the wooden wall members.
[0018] In this type of wooden earthquake-resistant wall structure, the wooden rigid frame member components are joined to the inside and outside of the corner formed by two wooden wall members arranged in a cross-sectional direction, and the corner forms a wooden rigid frame member, making it possible to join the two wooden wall members to form a corner with greater rigidity and strength.
[0019] The present invention also has wooden wall members which constitute a wooden earthquake-resistant wall, and wooden rigid frame member components which, together with the wooden wall members, constitute a wooden rigid frame member, wherein the wooden wall members are joined to the wooden rigid frame member components in such a manner that their ends extend into the wooden rigid frame member along the in-plane direction of the wooden wall members, and the length over which the ends of the wooden wall members extend into the wooden rigid frame member is equal to or longer than the length from the outer peripheral surface of the wooden rigid frame member into which the ends of the wooden wall members extend to the center of gravity of the wooden rigid frame member, The wooden wall structure has four of the wooden wall members and four of the wooden rigid frame member components, the four wooden wall members being arranged such that the ends of each of the wooden wall members are joined together and each of the wooden wall members extends in all four directions, and the four wooden rigid frame member components are provided in four recessed corners formed by two of the wooden wall members adjacent to each other, and are each joined to the two wooden wall members that form the recessed corners.
[0020] In this type of wooden earthquake-resistant wall structure, the ends of four wooden wall members are joined together and arranged so that each wooden wall member extends in all four directions, forming four internal corners. The ends of the four wooden wall members are joined together with the wooden rigid frame member components provided at each of the four internal corners, and these joints form a wooden rigid frame member, which makes it possible to join four wooden wall members in a cross shape with greater rigidity and strength.
[0021] The wooden shear wall unit of the present invention is a wooden shear wall unit that forms the above-mentioned wooden shear wall structure, and comprises the wooden wall members spanning multiple floors and the wooden rigid frame member components that form wooden beams provided at the boundaries between the multiple floors, and is characterized in that the ends of adjacent wooden shear wall units can be joined together when lined up in the in-plane direction of the wooden wall members.
[0022] This type of wooden earthquake-resistant wall unit has wooden wall components that span multiple floors and wooden beams that are installed at the boundaries between floors, so that by lining them up in-plane and joining adjacent ends, it is possible to easily form a wooden earthquake-resistant wall that spans multiple floors.
[0023] Such a wooden earthquake-resistant wall unit is characterized in that the wooden rigid frame member component constituting a wooden column is joined to one end of the wooden wall member. With such a wooden earthquake-resistant wall unit, it is possible to form a wooden earthquake-resistant wall unit that is integrated with a wooden column.

In addition, it is possible to easily build a multi-story shear wall by simply transporting the wooden shear wall units manufactured in a factory to a construction site and lining them up in the in-plane direction and joining them together. Effect of the Invention

[0028] The wooden shear-resistant wall structure, wooden shear-resistant wall unit, and construction method of the wooden shear-resistant wall unit according to this embodiment will be described with reference to the drawings.
[0029] The wooden earthquake-resistant wall 1 constituting the wooden earthquake-resistant wall structure of this embodiment has, for example, as shown in Figure 1, wooden beams 2 as wooden rigid frame members arranged vertically along the horizontal direction, wooden columns 3 as wooden rigid frame members to which the wooden beams 2 are erected vertically, and wooden wall members 4 whose ends 4a extend into the wooden beams 2 and wooden columns 3 to form one piece and constitute the wooden earthquake-resistant wall, and is installed in a building with a rigid frame structure.
[0030] The wooden wall member 4 may be, for example, a CLT (Cross Laminated Timber) material in which a number of planks are laminated and bonded together so that their grain directions are perpendicular to each other.
[0031] A wooden earthquake-resistant wall 1 of this embodiment is formed by a wooden beam 2 and a wooden column 3 together with an end portion 4a of a wooden wall member 4. First, a first embodiment which is the basic configuration of the wooden earthquake-resistant wall 1 will be described.
[0032] The wooden earthquake-resistant wall 1 of the first embodiment has a wooden beam component 5 as a wooden rigid frame component component that forms a wooden beam 2 together with the end portion 4a of the wooden wall member 4, a wooden column component 6 as a wooden rigid frame component component that forms a wooden column 3 together with the end portion 4a of the wooden wall member 4, and a wooden wall member 4.
[0033] More specifically, for example, two wooden column components 6 are adhered to the vertical end portion 4a of the rectangular wooden wall member 4, one on each side in the out-of-plane direction of the wooden wall member 4. Each of the two wooden column components 6 is provided over the entire length of the wooden wall member 4 in the up-down direction, and has the same horizontal width.
[0034] The wooden wall member 4 and the two wooden column components 6 are aligned and bonded together so that their end faces 4b, 6a are flush with each other. The area where the two wooden column components 6 and the wooden wall member 4 are bonded together forms a wooden column 3 that is rectangular in plan view, as shown in Fig. 2(a). In this manner, the wooden wall member 4 of this embodiment is provided so that the end 4a penetrates the wooden column 3, and the wooden wall member 4 enters from one side surface 3a, which is the outer peripheral surface of the wooden column 3 having a rectangular cross section, and the end face 4b of the wooden wall member 4 exceeds the center of gravity G of the wooden column 3, and the end face 4b is exposed on the opposite side of the wooden column 3.
[0035] In addition, each of the two wooden beam components 5 is provided along the horizontal direction of the wooden wall member 4, and the end portion is in contact with the wooden column component 6. The width of the two wooden beam components 5 in the vertical direction is the same. The wooden wall member 4 and the two wooden beam components 5 are bonded together so that their upper end faces 4b, 5a are flush with each other. As shown in FIG. 2(b), the portion where the wooden wall member 4 and the two wooden beam components 5 are bonded together forms a wooden beam 2 whose vertical cross section is rectangular when cut in the out-of-plane direction of the wooden wall member 4. In this way, the wooden wall member 4 of this embodiment is provided so that the end portion 4a penetrates the wooden beam 2, and the wooden wall member 4 enters from the side surface 2a as the outer peripheral surface of the wooden beam 2 whose cross section is rectangular, and the end surface 4b of the wooden wall member 4 exceeds the center of gravity G of the wooden beam 2, and the end surface 4b is exposed on the upper side of the wooden beam 2.
[0036] According to the wooden earthquake-resistant wall 1 of this embodiment, the end 4a of the wooden wall member 4 is arranged in a state where it enters the wooden beam constituent material 5 and the wooden column constituent material 6 along the in-plane direction of the wooden wall member 4, and is bonded to the wooden beam constituent material 5 and the wooden column constituent material 6, thereby forming the wooden beam 2 and the wooden column 3 together with the wooden beam constituent material 5 and the wooden column constituent material 6. Therefore, since the wooden wall member 4 and the wooden beam constituent material 5 are integrated to form the wooden beam 2, the shear force transmitted from the upper floor side of the wooden wall member 4 to the lower floor side can be borne by the entire wooden beam 2 and the wooden wall member 4 and transmitted to the lower floor. In addition, since the wooden wall member 4 and the wooden column constituent material 6 are integrated to form the wooden column 3, the additional axial force generated by bearing the shear force can be borne by the entire wooden wall member 4 and the wooden column 3.
[0037] Therefore, unlike conventional earthquake-resistant walls in which the columns and beams are joined to the wooden wall with gusset plates and drift pins, or where cotters are provided on both and joined by engaging the cotters, there is no need to transmit force between the columns or beams and the separated wooden wall. This makes it possible to provide a wooden earthquake-resistant wall 1 with higher rigidity and strength.
[0038] 2(a) and 2(b), the wooden wall member 4 enters from one side surface 2a, 3a of the wooden beam 2 and wooden column 3, which have a rectangular cross section, and its end surface 4b is exposed on the opposite side of the wooden beam 2 and wooden column 3. In other words, the length L of the end portion 4a of the wooden wall member 4 entering the wooden beam 2 and wooden column 3 is equal to or longer than the length Lg from the side surfaces 2a, 3a of the wooden beam 2 and wooden column 3, which are the outer peripheral surfaces into which the end portion 4a enters, to the center of gravity G of the wooden beam 2 and wooden column 3, so that the shear force and additional axial force can be directly transmitted to the center of gravity G of the wooden beam 2 and wooden column 3.
[0039] In addition, it is possible to easily construct a wooden earthquake-resistant wall 1 in which the wooden beam 2 and wooden column 3 are integrated with the wooden wall member 4 by simply joining a wooden beam component 5 and a wooden column component 6 to the end portion 4a of the wooden wall member 4 from both sides in the out-of-plane direction of the wooden wall member 4.
[0040] In the above embodiment, an example has been described in which two wooden beam constituent members 5 or two wooden column constituent members 6 are adhered to the end portion 4a of the wooden wall member 4, one each from both sides in the out-of-plane direction of the wooden wall member 4, but the present invention is not limited to this. For example, as shown in Figures 3(a) to 3(c), slits 5b, 6b having a width slightly wider than the thickness of the wooden wall member 4 may be provided along the longitudinal direction on one outer surface of the wooden beam constituent member 5 or wooden column constituent member 6 having a rectangular cross section, and the end portion 4a of the wooden wall member 4 may be inserted into the slits 5b, 6b to adhere the inner surfaces of the slits 5b, 6b to the wooden wall member 4. In this case, it is desirable that the slits 5b, 6b are formed up to the position of the center of gravity G of the wooden beam 2 formed by the wooden beam component 5 having the slits 5b, 6b and the end 4a of the wooden wall member 4, or the wooden column 3 formed by the wooden column component 6 and the end 4a of the wooden wall member 4, or up to a position deeper than the position of the center of gravity G.
[0041] In addition, in the above embodiment, an example was described in which the wooden beam component 5 and / or the wooden column component 6 was glued to the wooden wall member 4, but this is not limited to the above, and the components may be joined using a fastening material such as a drift pin.
[0042] As shown in Figure 4, the second embodiment of a wooden earthquake-resistant wall 1 has a wooden column 3 having an end 4a of a wooden wall member 4 and wooden column components 60, 61 glued to it along the in-plane direction, and a beam (hereinafter referred to as an orthogonal beam) 7 extending in a direction intersecting the wooden wall member 4.
[0043] For example, when an orthogonal beam 7 is provided at the upper end of the wooden column 3 along a direction orthogonal to the wooden wall member 4, a wall member notch 4c in which the orthogonal beam 7 can be placed is provided at the upper end of the wooden wall member 4 that is to be placed inside the wooden column 3. The wall member notch 4c is cut out from the horizontal end face 4b of the wooden wall member 4 by the thickness of the orthogonal beam 7, and from the upper end face 4b of the wooden wall member 4 by the vertical width of the orthogonal beam 7. Therefore, when the orthogonal beam 7 is placed in the wall member notch 4c of the wooden wall member 4, the upper surface 7a of the orthogonal beam 7 and the upper end face 4b of the wooden wall member 4 are arranged to be substantially flush with each other, and the surface 7b of the orthogonal beam 7 that does not face the wooden wall member 4 and the horizontal end face 4b of the wooden wall member 4 are arranged to be substantially flush with each other.
[0044] When an orthogonal beam 7 is provided, there are two first wooden column components 60, one glued to each side of the wooden wall member 4 in the out-of-plane direction, and a second wooden column component 61 glued to the side 60b as the outer peripheral surface of the first wooden column component 60, the horizontal end face 4b of the wooden wall member 4, and the face 7b of the orthogonal beam 7 that does not face the wooden wall member 4.
[0045] The first wooden column component 60 has the same shape as the end portion 4a that forms the wooden column 3 in the wooden wall member 4. That is, a structural material notch portion 60a in which the orthogonal beam 7 is disposed is provided at the upper end portion.
[0046] The second wooden column component 61 has a width along the longitudinal direction of the orthogonal beam 7 that is the same as the width in the out-of-plane direction when the two first wooden column components 60 are bonded to the wooden wall member 4, and is arranged to form a wooden column 3 that is rectangular in plan view when bonded together with the two first wooden column components 60 and the end 4a of the wooden wall member 4, as shown in Fig. 5. At this time, the center of gravity G of the wooden column 3 is located in the wall member notched portion 4c of the wooden wall member 4, and the left-right end face 4b of the wooden wall member 4 is located further back than the center of gravity G of the wooden column 3. In other words, the length L of the end 4a of the wooden wall member 4 that penetrates into the wooden column 3 is longer than the length Lg from the side face 3a of the wooden beam 2 and the wooden column 3 into which the end 4a penetrates to the center of gravity G.
[0047] By providing the orthogonal beams 7 in the wooden earthquake-resistant wall 1 in this way, it is possible to easily form the wooden earthquake-resistant wall 1 which is integrated with the orthogonal beams 7 arranged in a direction intersecting with the wooden wall members 4 and the wooden columns 3. This makes it possible to easily construct a column-beam structure with higher rigidity and strength.
[0048] In addition, the length of the orthogonal beams 7 provided in the wooden earthquake-resistant wall 1 is preferably a length that can be transported by truck, for example. When connecting the orthogonal beams 7 in a row in the longitudinal direction, for example, as shown in Figures 6(a) and 6(b), a slit-shaped recess 7c is provided on each end surface of the two orthogonal beams 7 to be connected, and a gusset plate 8 is placed in the recess 7c of each orthogonal beam 7 so as to span both orthogonal beams 7, and a drift pin P is driven into the recess 7c to connect them. Alternatively, as shown in Figure 7, a recess 7d is provided on each end surface of the two orthogonal beams 7 to be connected, and a cotter is provided using the recess 7d and a piece member 9 inserted into the recess 7d. Furthermore, a recess 7e is provided on each of the upper and lower surfaces of the orthogonal beam 7 so as to connect both orthogonal beams 7, and a reinforcing flange 10 is placed across both orthogonal beams 7 and bonded to the recess 7e.
[0049] 8, a wooden earthquake-resistant wall 1 of the third embodiment has two wooden wall members 40, 41 joined at their ends 40a, 41a to form an L-shaped corner in a plan view. The wooden earthquake-resistant wall 1 in which two wooden wall members 4 are joined in an L-shape in a plan view has the two wooden wall members 40, 41, two wooden column components 11, 12 respectively arranged on the inside and outside of the corner formed by the L-shaped joined wooden wall members 40, 41, and two wooden beam components 5 arranged on both sides of the upper ends of the two wooden wall members 40, 41 along the in-plane direction.
[0050] Of the two wooden wall members 40, 41, an end 40a of one wooden wall member 40 has a first convex portion 40b that protrudes in the in-plane direction and a first concave portion 40c that is recessed in the in-plane direction, and an end 41a of the other wooden wall member 41 has a second convex portion 41b that protrudes in the in-plane direction and fits into the first concave portion 40c, and a second concave portion 41c that is recessed in the in-plane direction and fits into the first convex portion 40b. That is, the two wooden wall members 40, 41 are arranged so as to form an L-shape when viewed from above, with the first convex portion 40b provided on the end portion 40a of one of the wooden wall members 40 fitting into the second concave portion 41c provided on the end portion 41a of the other wooden wall member 41, and the second convex portion 41b provided on the end portion 41a of the other wooden wall member 41 fitting into the first concave portion 40c provided on the end portion 40a of the one wooden wall member 40, and are joined and bonded to form a corner by a so-called dovetail joint.
[0051] The wooden column component 11 (hereinafter also referred to as the inner wooden column component) arranged inside the corner formed by the two wooden wall members 40, 41 has a prismatic shape with a rectangular cross section and is arranged with its longitudinal direction along the up-down direction. The two adjacent side surfaces 11a of the inner wooden column component 11 are bonded to the inside of the end portions 40a, 41a of the two wooden wall members 40, 41 that form the corner.
[0052] The wooden column component 12 (hereinafter also referred to as the outer wooden column component) placed on the outside of the corner formed by the two wooden wall members 40, 41 has an L-shaped cross section when viewed in a plane, and the two inner side surfaces 12a forming the perpendicular corner are each glued to the outside of the corner formed by the end portions 40a, 41a of the two wooden wall members 40, 41.
[0053] When the inner wooden column component 11 and the outer wooden column component 12 are bonded to the two wooden wall members 40, 41 joined and bonded with dovetail joints, the ends 40a, 41a of the two wooden wall members 40, 41 and the inner wooden column component 11 and the outer wooden column component 12 form a wooden column 3 that is rectangular in plan view, as shown in Fig. 9. At this time, the lengths L of the two wooden wall members 40, 41 from the side surface 3a of the wooden column 3 to the ends are both longer than the length Lg from the side surface 3a of the wooden column 3 to the center of gravity G of the wooden column 3.
[0054] The two wooden beam components 5 are bonded to both sides of the upper end portions 4a of the two wooden wall members 4, respectively, to form a wooden beam 2 having a rectangular cross section. The configuration of the wooden beam 2 in this embodiment is the same as that of the wooden beam 2 in the first embodiment. That is, as shown in FIG. 2(b), the two wooden wall members 4 penetrate the wooden beam 2 in the vertical direction, and therefore, the length L from the outer peripheral surface 2a of the wooden beam 2 to the upper end surface 4b of each of the two wooden wall members 4 that penetrate the wooden beam 2 is longer than the length Lg from the outer peripheral surface 2a of the wooden beam 2 to the center of gravity G of the wooden beam 2.
[0055] In such a wooden earthquake-resistant wall 1 having a corner formed by two wooden wall members 4, in which two wooden column components 11, 12 are glued to the upper ends 4a of the two wooden wall members 4 to form a single wooden beam 2, the length L of the wooden wall member 4 extending into the wooden beam 2 from its outer peripheral surface 2a is longer than the length Lg from the outer peripheral surface 2a of the wooden beam 2 to the center of gravity G of the wooden beam 2, so that shear force can be transmitted directly to the center of gravity G of the wooden beam 2.
[0056] Furthermore, wooden column components 11, 12 are joined from the inside and outside of a corner formed by two wooden wall members 4 arranged in mutually perpendicular directions, respectively, to form a single unit, and the corner forms the wooden column 3. At this time, the length L by which the end 4a of the wooden wall member 4 penetrates into the wooden column 3 is longer than the length Lg from the side surface 3a of the wooden column 3 to the center of gravity G, so that the additional axial force generated by bearing the shear force can be directly transmitted to the center of gravity G of the wooden column 3. For this reason, it is possible to join two wooden wall members 4 to form a corner with higher rigidity and strength.
[0057] As shown in FIG. 10, the wooden earthquake-resistant wall 1 of the fourth embodiment is made up of two wooden wall members (hereinafter also referred to as parallel wooden wall members) 42, 43 arranged horizontally side by side to form the same plane, and a wooden wall member (hereinafter also referred to as intersecting wooden wall member) 44 arranged in a direction perpendicular to the parallel wooden wall members 42, 43 and joined in an upright position, which are joined together with wooden column components 13, 14 to form a T-shape in a plan view, and has wooden beam components 5 arranged on both sides of the upper ends 42a, 43a, 44a of each wooden wall member 42, 43, 44 along the in-plane direction.
[0058] The two juxtaposed wooden wall members 42, 43 are arranged so that their ends are butted together, and the intersecting wooden wall member 44 is arranged so that its end 44a is joined to the butted ends 42a, 43a of the two juxtaposed wooden wall members 42, 43 by a dovetail joint.
[0059] The horizontal end 44a of the intersecting wooden wall member 44 is provided with a third convex portion 44b protruding in the in-plane direction and a third concave portion 44c recessed in the in-plane direction, and the horizontal ends 42a, 43a of the two juxtaposed wooden wall members 42, 43 are provided with fourth convex portions 42b, 43b protruding in the in-plane direction and fitting with the third concave portion 44c, and fourth concave portions 42c, 43c recessed in the in-plane direction and fitting with the third convex portion 44b and the fourth convex portions 42b, 43b of the other juxtaposed wooden wall members 42, 43. That is, the ends 42a, 43a of the two juxtaposed wooden wall members 42, 43 face each other, and the fourth convex portions 42b, 43b are inserted into the fourth concave portions 42c, 43c of the other.
[0060] In this state, in each fourth recess 42c, 43c, the fourth convex portions 42b, 43b of the other juxtaposed wooden wall members 42, 43 are inserted into the vertical center of the fourth recess 42c, 43c, and gaps S exist above and below the inserted fourth convex portions 42b, 43b, with the two juxtaposed wooden wall members 42, 43 forming one plane. The intersecting wooden wall member 44 is disposed along the out-of-plane direction of the juxtaposed wooden wall members 42, 43, and the third convex portion 44b provided on the end portion 44a is inserted into the gap S existing in the fourth recesses 42c, 43c of the two juxtaposed wooden wall members 42, 43. In this way, the third convex portion 44b and the fourth convex portions 42b, 43b are both fitted into the fourth concave portions 42c, 43c, and the three wooden wall members 42, 43, 44 are joined and adhered together so as to form a T-shape in a plan view.
[0061] The three wooden wall members 42, 43, 44, which are joined to form a T-shape in plan view, are bonded together with a wooden column component (hereinafter also referred to as a planar wooden column component) 13 arranged on the opposite side of the juxtaposed wooden wall members 42, 43 from the intersecting wooden wall member 44, and two wooden column components (hereinafter referred to as inside corner wooden column components) 14 arranged in each of the inside corners formed by one of the two juxtaposed wooden wall members 42, 43 and the intersecting wooden wall member 44. The planar wooden column component 13 and the two inside corner wooden column components 14 are all arranged over the entire length of the three wooden wall members 42, 43, 44 in the vertical direction.
[0062] The juxtaposed wooden wall member 43 is arranged and glued across the two juxtaposed wooden wall members 42, 43, distributed left and right around the intersecting wooden wall member 44 in the in-plane direction of the juxtaposed wooden wall member 43. The inside corner wooden column component 14 has a rectangular prism shape in a plan view, and two adjacent side surfaces 14a are glued to the ends 42a, 43a, 44a of the juxtaposed wooden wall members 42, 43 and the intersecting wooden wall member 44 that form the inside corner.
[0063] When the planar wooden column component 13 and the two inside-corner wooden column components 14 are bonded to the three wooden wall members 42, 43, 44 that are joined to form a T-shape in plan view, the ends 42a, 43a, 44a of the three wooden wall members 42, 43, 44, the planar wooden column component 13, and the two inside-corner wooden column components 14 form a wooden column 3 that is rectangular in plan view, as shown in Figure 11. At this time, the lengths L of the three wooden wall members 42, 43, 44 from the side surface 3a of the wooden column 3 are all longer than the length Lg from the side surface 3a of the wooden column 3 to the center of gravity G of the wooden column 3.
[0064] The wooden beam constituent material 5 is bonded to both sides of the upper end portions 42a, 43a, and 44a of the wooden wall members 42, 43, and 44, respectively, to form a wooden beam 2 having a rectangular cross section. The wooden beam 2 of this embodiment has the same structure as the wooden beam 2 of the first embodiment. That is, as shown in FIG. 2(b), the two wooden wall members 4 penetrate the wooden beam 2 in the vertical direction, so that the length L from the outer peripheral surface 2a of the wooden beam 2 to the upper end surface 4b of the two wooden wall members 4 that are inserted into the wooden beam 2 is longer than the length Lg from the outer peripheral surface 2a of the wooden beam 2 to the center of gravity G of the wooden beam 2. Therefore, the shear force is directly transmitted to the center of gravity G of the wooden beam 2.
[0065] In addition, the horizontal ends 42a, 43a, 44a of the three wooden wall members 42, 43, 44 arranged to form a T-shape in plan view are bonded to the planar wooden column component 13 and the two inside corner wooden column components 14 to form a single unit, and the joints of the three wooden wall members 42, 43, 44 form the wooden column 3. At this time, the length L of the horizontal ends 42a, 43a, 44a of the wooden wall members 42, 43, 44 that are inserted into the wooden column 3 is longer than the length Lg from the side surface 3a of the wooden column 3 to the center of gravity G, so that the additional axial force generated by bearing the shear force is directly transmitted to the center of gravity G of the wooden column 3. For this reason, it is possible to join the three wooden wall members 42, 43, 44 to form a T-shape with higher rigidity and strength.
[0066] As shown in FIG. 12 , in the wooden earthquake-resistant wall 1 of the fifth embodiment, the ends 45a, 46a, 47a, 48a of four wooden wall members 45, 46, 47, 48 are joined together so that each wooden wall member 45, 46, 47, 48 extends in all four directions, two of the four wooden wall members 45, 46, 47, 48 are aligned in the in-plane direction and the ends 45a, 46a, 47a, 48a are butted together to form wall surfaces along two directions that are perpendicular to each other to form a cross shape in a plan view, and the four wooden wall members 45, 46, 47, 48 are joined together so that the wall surfaces along the two directions are perpendicular to each other to form a cross shape in a plan view, and the upper ends 45a, 46a, 47a, 48a of each wooden wall member 45, 46, 47, 48 have wooden beam components 5 arranged on both sides along the in-plane direction.
[0067] The four wooden wall members 45, 46, 47, 48 are arranged such that two wooden wall members (hereinafter also referred to as first wooden wall members) 45, 46 forming one wall surface have ends 45a, 46a that butt against each other, and two wooden wall members (hereinafter also referred to as second wooden wall members) 47, 48 forming the other wall surface have ends 47a, 48a that are joined by a dovetail joint.
[0068] The end portions 45a, 46a of the first wooden wall members 45, 46 are provided with fifth convex portions 45b, 46b protruding in the in-plane direction and fifth concave portions 45c, 46c recessed in the in-plane direction. The vertical width of the fifth convex portions 45b, 46b and the vertical width of the fifth concave portions 45c, 46c are formed to be the same, and the fifth convex portions 45b, 46b and the fifth concave portions 45c, 46c are provided alternately in the vertical direction. The fifth convex portions 45b, 46b are provided at a thickness half the thickness of the first wooden wall members 45, 46, and are arranged biased toward one of the surfaces in the out-of-plane direction. The fifth concave portions 45c, 46c also penetrate the first wooden wall members 45, 46 in the thickness direction.
[0069] The fifth convex portions 45b, 46b provided on the ends 45a, 46a of the two first wooden wall members 45, 46 are positioned in the same vertical direction, and the fifth convex portions 45b, 46b of each of the first wooden wall members 45, 46 are provided on opposite surfaces in the out-of-plane direction. Therefore, when the ends 45a, 46a of the two first wooden wall members 45, 46 are butted together, the portions where the fifth convex portions 45b, 46b of each of the first wooden wall members 45, 46 face each other in the out-of-plane direction and overlap with each other in the out-of-plane direction, and the voids S formed by the fifth concave portions 45c, 46c of the two first wooden wall members 45, 46 penetrating in the out-of-plane direction are alternately arranged in the vertical direction.
[0070] The ends 47a, 48a of the second wooden wall members 47, 48 are provided with sixth convex portions 47b, 48b protruding in the in-plane direction and sixth concave portions 47c, 48c recessed in the in-plane direction. The sixth convex portions 47b, 48b provided on each of the second wooden wall members 47, 48 are arranged so as to fit into a gap S formed by the fifth concave portions 45c, 46c of the two first wooden wall members 45, 46 and penetrating in the out-of-plane direction. For example, one of the two second wooden wall members 47, 48, for example the second wooden wall member 47, is provided with a sixth convex portion 47b at a position where it fits into an odd-numbered gap S from above of the gap S formed by the fifth recesses 45c, 46c arranged side by side in the vertical direction, and the other of the two second wooden wall members is provided with a sixth convex portion 48b at a position where it fits into an even-numbered gap S from above of the gap S formed by the fifth recesses 45c, 46c arranged side by side in the vertical direction. That is, the sixth convex portions 47b, 48b of the second wooden wall members 47, 48 arranged on both sides of the first wooden wall members 45, 46 in the out-of-plane direction are fitted into the gap S formed by the ends 45a, 46a of the two first wooden wall members 45, 46 butted together, and the four wooden wall members 45, 46, 47, 48 are joined and bonded to form a cross shape in a plan view.
[0071] The four wooden wall members 45, 46, 47, 48, which are joined to form a cross shape in plan view, are bonded together with four wooden column components (hereinafter also referred to as rectangular wooden column components) 15, which are respectively arranged in four recessed corners formed by two perpendicular walls. The rectangular wooden column components 15 are all arranged in the vertical direction over the entire length of the four wooden wall members 45, 46, 47, 48. The rectangular wooden column components 15 are rectangular pillars in plan view, and two adjacent side surfaces 15a are bonded to the ends 45a, 46a, 47a, 48a of the two wooden wall members 45, 46, 47, 48 that form the recessed corners.
[0072] When four rectangular wooden column components 15 are bonded to four wooden wall members 45, 46, 47, 48 joined to form a cross shape in plan view, the ends 45a, 46a, 47a, 48a of the four wooden wall members 45, 46, 47, 48 and the four rectangular wooden column components 15 form a rectangular wooden column 3 in plan view, as shown in Fig. 13. At this time, the length L of each of the four wooden wall members 45, 46, 47, 48 extending from the side surface 3a of the wooden column 3 into the wooden column 3 is longer than the length Lg from the side surface 3a of the wooden column 3 to the center of gravity G of the wooden column 3.
[0073] The wooden beam constituent material 5 is bonded to both sides of the upper end portions 45a, 46a, 47a, 48a of the wooden wall members 45, 46, 47, 48, respectively, and is integrated to form the wooden beam 2 having a rectangular cross section. The wooden beam 2 of this embodiment has the same structure as the wooden beam 2 of the first embodiment. That is, as shown in FIG. 2(b), the two wooden wall members 4 penetrate the wooden beam 2 in the vertical direction, so that the length L from the outer peripheral surface 2a of the wooden beam 2 to the upper end surface 4b of the two wooden wall members 4 that are inserted into the wooden beam 2 is longer than the length Lg from the outer peripheral surface 2a of the wooden beam 2 to the center of gravity G of the wooden beam 2. Therefore, the shear force is directly transmitted to the center of gravity G of the wooden beam 2.
[0074] In addition, the length L of the ends 45a, 46a, 47a, 48a of the wooden wall members 45, 46, 47, 48 that extend into the wooden column 3 is longer than the length Lg from the side surface 3a of the wooden column 3 to the center of gravity G, so that the additional axial force generated by bearing the shear force can be directly transmitted to the center of gravity G of the wooden column 3. For this reason, it is possible to join the four wooden wall members 45, 46, 47, 48 in a cross shape with higher rigidity and strength.
[0075] In the above embodiment, the wooden earthquake-resistant wall 1 has been described as comprising wooden column components 6, 11, 12, 13, 14, 15 and wooden beam components 5 bonded to wooden wall members 4, 40, 41, 42, 43, 44, 45, 46, 47, 48 to form an earthquake-resistant wall for one floor. However, as shown in FIG. 14, the wooden wall members may be unitized to form earthquake-resistant walls spanning multiple floors.
[0076] Specifically, the wooden earthquake-resistant wall units 16, 17 are formed to a size that allows them to be transported by a transport vehicle such as a truck, and for example, have wooden wall members 49 that are three stories high (approximately 12 m) and approximately 2 m wide, and wooden beam components 5 that are provided at the boundaries between each floor. Also, the wooden earthquake-resistant wall unit 17 that is connected to a column has a wooden column component 18 that runs along the entire length in the up-down direction at one end in the left-right direction of the wooden wall member 49.
[0077] The joint between the wooden wall member 49 and the wooden beam component 5 and the wooden column component 18 in the wooden earthquake-resistant wall unit 16, 17 is, for example, the same as in the first embodiment. That is, the wooden beam component 5 and the wooden column component 18 are bonded to both sides of the wooden wall member 49. The wooden beam component 5 is provided at the position of the beam provided on each floor. For example, when the earthquake-resistant walls from the first floor to the third floor are constructed using the wooden earthquake-resistant wall units 16, 17, the wooden beam component 5 provided at the upper end 49a of the wooden wall member 49 becomes the wooden beam 2 provided on the third floor. The wooden beam component 5 provided second from the top becomes the wooden beam 2 provided at the position supporting the floor of the third floor, and the wooden beam component 5 provided third from the top becomes the wooden beam 2 provided at the position supporting the floor of the second floor.
[0078] Such wooden earthquake-resistant wall units 16, 17 are manufactured, for example, in a factory by appropriately gluing the wooden wall members 49 to the wooden beam components 5 and the wooden column components 18 (factory manufacturing step), and then transported to the construction site by a transport vehicle such as a truck. The wooden earthquake-resistant wall units 16, 17 transported to the construction site are lined up in the left-right direction, and adjacent wooden earthquake-resistant wall units 16, 17 on the left and right are joined together (joining step).
[0079] The wooden wall members 49 of the wooden earthquake-resistant wall units 16, 17 adjacent to each other in the left-right direction are joined by providing the seventh protrusions 49b protruding from the center in the thickness direction on the opposing ends 49a of the wooden wall members 49 of the two adjacent wooden earthquake-resistant wall units 16, 17, as shown in Fig. 15(a). When the two wooden earthquake-resistant wall units 16, 17 are arranged side by side with the ends with the seventh protrusions 49b butted against each other, boundary recesses 49c that connect the two wooden wall members 49 and recess in the out-of-plane direction are formed on both sides along the up-down direction. A plate-shaped connecting member 19 is placed in each boundary recess 49c so as to straddle the two wooden wall members 49, and the two wooden wall members 49 are connected by clamping the seventh protrusions 49b between the two connecting members 19 and fastening them with screws.
[0080] Also, as shown in Figure 15 (b), a slit 49e recessed in the in-plane direction may be formed in each of the butted end faces 49d of the wooden wall members 49 of two adjacent wooden earthquake-resistant wall units 16, 17, and with the wooden wall members 49 of the two wooden earthquake-resistant wall units 16, 17 butted together, a metal plate 20 may be inserted across the slits 49e of both wooden wall members 49, and the wooden wall members 49 and the plate 20 may be connected by driving in a fastening material that extends in the out-of-plane direction.
[0081] 15(c) and 15(d), a wall convex portion 49f protruding in the in-plane direction and a wall concave portion 49g recessed in the in-plane direction may be provided at the butted ends 49a of the wooden wall members 49 of two adjacent wooden earthquake-resistant wall units 16, 17, respectively, with the positions of the wall convex portion 49f and the wall concave portion 49g opposite each other, and the wall convex portion 49f of one wooden wall member 49 and the wall concave portion 49g of the other wooden wall member 49 may be joined by combining and gluing them together.
[0082] In addition, when joining wooden beams 2 of two adjacent wooden earthquake-resistant wall units 16, 17, for example, as shown in Fig. 16, a beam convex portion 2c protruding in the longitudinal direction of the wooden beam 2 and a beam concave portion 2d concave in the longitudinal direction of the wooden beam 2 may be provided at the end portion 2a of each wooden beam 2, with the beam convex portion 2c and the beam concave portion 2d positioned opposite each other, and the beam convex portion 2c of one wooden beam 2 and the beam concave portion 2d of the other wooden beam 2 may be combined and bonded to connect them. At this time, semicircular grooves 2e are provided on the upper and lower surfaces of the beam convex portion 2c and the beam concave portion 2d, respectively, in the vertical direction along the outward direction of the concave surface. The groove 2e of the beam convex portion 2c and the groove 2e of the beam concave portion 2d are configured so that when the beam convex portion 2c of one wooden beam 2 is inserted into the beam concave portion 2d of the other wooden beam 2, they overlap vertically to form a through hole along the out-of-plane direction, and after the beam convex portion 2c of one wooden beam 2 is inserted into the beam concave portion 2d of the other wooden beam 2, a dowel 21 is inserted into the through hole to connect them.
[0083] Furthermore, when connecting the wooden shear wall units 16, 17 in the vertical direction, for example, as shown in Figure 17, holes along the vertical direction are formed in the lower end 17a of the upper wooden shear wall unit 17 and the upper end 17a of the lower wooden shear wall unit 17 in a factory or the like in such a way that they are aligned with each other, and the upper and lower wooden shear wall units 17 are connected on site using a so-called GIR (Glued in Rod) joint, in which adhesive is injected into the holes formed in the upper and lower wooden shear wall units 17 and rod-shaped connectors 22 are inserted and joined by the adhesive hardening. Although not shown, when connecting wooden earthquake-resistant wall units 16 in the vertical direction, holes along the vertical direction are formed in the lower end 16a of the upper wooden earthquake-resistant wall unit 16 and the upper end 16a of the lower wooden earthquake-resistant wall unit 16, respectively, in a factory or the like so that they are aligned with each other. At site, adhesive is injected into the holes formed in the upper and lower wooden earthquake-resistant wall units 16 and rod-shaped connectors 22 are inserted and the units are joined by the adhesive hardening.
[0084] According to the wooden earthquake-resistant wall units 16, 17 of this embodiment, which have wooden wall members 49 spanning multiple floors and wooden beams 2 provided at the boundaries between each floor, it is possible to easily provide an earthquake-resistant wall spanning multiple floors by arranging the wooden earthquake-resistant wall units 16, 17 in the in-plane direction and joining adjacent ends.
[0085] Furthermore, according to this construction method for the wooden earthquake-resistant wall units 16, 17, it is possible to easily manufacture the wooden earthquake-resistant wall units 16, 17 with higher precision in a factory, and by simply transporting them to the construction site and joining them in the in-plane direction, it is possible to easily build an earthquake-resistant wall spanning multiple floors.
[0086] The above-mentioned embodiment is for the purpose of facilitating understanding of the present invention, and is not intended to limit the present invention. The present invention can be modified or improved without departing from the spirit of the present invention, and it goes without saying that the present invention includes equivalents thereof.
