Description

  The present invention relates to a seismic wall.

  Conventionally, in order to increase the seismic strength of existing buildings, there are cases where seismic walls are installed in the column beam frame. As this earthquake-resistant wall, there exists a thing made from reinforced concrete, for example (for example, refer to patent documents 1). In this prior art seismic wall, the steel frame material made of channel steel is attached to the column beam frame with the groove shape of the steel frame material facing inwardly along the inner surface of the column beam frame, In addition, anchor bars protrude inward from the groove bottom of the steel frame material. Thereafter, a wall formwork is assembled along the inner surface of the column beam frame, and concrete is placed on the formwork to form an earthquake resistant wall.

JP 2001-27048 A

  However, in the conventional seismic walls, those made of reinforced concrete are heavy, and the weight of the building increases with the installation of the seismic wall, so that the building may need to be reinforced.

  These problems can be solved by configuring the earthquake resistant wall using a material having a specific gravity smaller than that of reinforced concrete.

  For example, the present applicant has proposed a seismic wall using wood as a material having a small specific gravity (Japanese Patent Application No. 2007-125752). In this seismic wall, a plurality of lattice units made of a wooden material are joined to the inner peripheral surface of a peripheral frame made of a wooden material fixed along the inner peripheral surface of the column beam frame. According to such a seismic wall, it is possible to reduce the weight and to resist the horizontal load accompanying the occurrence of the earthquake. However, in the market, there may be demands for further improved earthquake resistance.

  The present invention has been made in view of the above, and an object of the present invention is to provide a seismic wall that can further improve seismic resistance while following weight reduction.

  In order to solve the above-described problems and achieve the object, a seismic wall according to claim 1 of the present invention is a seismic wall configured in a frame composed of columns and beams of a building, and is made of a wooden material, A peripheral frame disposed along the inner periphery of the frame, a plurality of lattice units each composed of a wood material, and disposed in a manner of closing a space surrounded by the peripheral frame, and a plurality of joining members each composed of a wood material And a recess is provided at each of the peripheral frame and the lattice unit facing each other, and the joining member is fitted into an insertion hole formed by the recess.

  The earthquake-resistant wall according to claim 2 of the present invention is the above-described earthquake resistant wall according to claim 1, wherein concave portions are provided in mutually facing portions of adjacent lattice units, and the joining member is inserted into an insertion hole formed by the concave portion. Further, it is fitted.

  Furthermore, the earthquake-resistant wall according to claim 3 of the present invention is the above-described earthquake resistant wall according to claim 1 or 2, wherein the joining member is obtained by impregnating a plurality of laminated single plates with a thermosetting resin and hot-pressing them. When the joining member is fitted into the insertion hole, the laminated surface of the plurality of single plates is configured to be in a direction intersecting with the opposing surface of the member forming the insertion hole.

  According to a fourth aspect of the present invention, in the earthquake resistant wall according to the third aspect, when the joining member is fitted into the insertion hole, the laminated surface of the plurality of single plates fits the joining member. It is characterized by being configured so as to be orthogonal to the direction of joining.

  Furthermore, the earthquake-resistant wall according to claim 5 of the present invention is the above-described earthquake resistant wall according to claim 3, wherein the fiber direction of the plurality of single plates forms the insertion hole when the joining member is fitted into the insertion hole. It is comprised so that it may become the direction which cross | intersects the opposing surface of the member to do.

  In the earthquake-resistant wall according to the present invention, the peripheral frame, the lattice unit, and the joining member are configured using a wood material. Wood material has a higher specific strength than reinforced concrete. Therefore, a seismic wall using a wooden material can be reduced in weight even when it has the same strength as a reinforced concrete seismic wall. Moreover, the joining member is configured to be fitted into the insertion hole formed by the recesses of the peripheral frame and the recesses of the lattice unit facing each other. For this reason, for example, when a force is applied to move the peripheral frame and the lattice unit in different directions along the construction surface of the frame due to the occurrence of an earthquake, the joining member resists the force. As a result, the movement of the peripheral frame and the lattice unit is prevented. Therefore, the earthquake resistance of the building can be improved.

  Examples of the wood material to be applied to the peripheral frame 20 include a laminated material obtained by adhering several thin wood plates, and a reinforced wood obtained by impregnating a plurality of laminated single plates with a thermosetting resin and heat-pressing them. In the present embodiment, reinforced wood using a phenol resin as a thermosetting resin is employed for the peripheral frame 20.

  As shown in FIG. 2, the peripheral frame 20 and the frame 100 are joined by a plurality of bolt members 50. The plurality of bolt members 50 are provided from the peripheral frame 20 to the frame 100 as many as necessary to fix the peripheral frame 20 to the frame 100. Here, the bolt member 50 is preferably selected as appropriate depending on the material of the frame 100. Examples of the bolt member 50 applied to the non-wooden frame 100 include a well-known steel anchor bolt. On the other hand, the bolt member 50 applied to the wooden frame 100 includes a screw bolt. Note that FIG. 2 illustrates the case where the frame 100 is made of wood.

  Each of the plurality of lattice units 30 is made of a wood material, and is arranged in a manner that closes a space surrounded by the peripheral frame 20. Each of the plurality of lattice units 30 includes a panel 31 and a frame member 32.

  The panel 31 is a substantially rectangular plate material. As a wood material applied to the panel 31, a reinforced wood obtained by impregnating a plurality of laminated single plates with a thermosetting resin and heat-pressing is optimal. In the present embodiment, a reinforced wood using a phenol resin as a thermosetting resin is employed for the panel 31.

  The frame member 32 is provided on the entire periphery of the panel 31. The frame member 32 is provided with an opening 32a and a plurality of recesses 32b. The opening 32a is a substantially rectangular opening. The plurality of recesses 32 b are grooves that open toward the outside of the frame member 32, and are disposed at predetermined positions on the outer peripheral edge of the frame member 32. The plurality of recesses 32 b are configured to face the recesses 22 of the peripheral frame 20 and the recesses 32 b of the adjacent frame members 32 when the frame member 32 is disposed in the frame 100. The wood material to be applied to the frame member 32 is a laminated lumber obtained by bonding several thin sheets of wood, main lumber or thinned lumber, and a plurality of laminated single plates impregnated with thermosetting resin and hot pressed to strengthen There are trees. In the present embodiment, a reinforced wood using a phenol resin as a thermosetting resin is employed for the frame member 32.

  Although not explicitly shown in the figure, the panel 31 and the frame member 32 are joined with an adhesive. An appropriate amount of this adhesive is applied to the contact portion between the panel 31 and the frame member 32.

  Moreover, the earthquake-resistant wall 10 is provided with the some cotter (joining member) 40, as shown in FIG. As shown in FIG. 3, the plurality of cotters 40 are made of reinforced wood that is impregnated with thermosetting resin into a plurality of single plates 41 that are laminated so that the fiber directions are aligned in substantially the same direction. Is a substantially rectangular columnar member. In the present embodiment, a phenol resin is employed for the cotter 40 as a thermosetting resin.

  As shown in FIGS. 1 and 3, when the peripheral frame 20 and the plurality of lattice units 30 are disposed in the frame 100, the plurality of cotters 40 include the recesses 22 of the peripheral frame 20 and the plurality of lattice units 30. Is fitted into an insertion hole 25 formed by facing the recess 32b of the frame member 32. In the present embodiment, the cross-sectional shape of the cotter 40 is substantially the same as the opening shape of the insertion hole 25, thereby preventing a gap from being opened between the cotter 40 and the insertion hole 25. However, when the gap is opened, it is desirable to fill the gap with a buried wood member made of a wooden material. The wood materials to be applied to buried members include laminated timber with several thin timbers bonded together, main timber or thinned timber, and laminated wood that has been impregnated with thermosetting resin and heat pressed. and so on.

  Here, the plurality of cotters 40 are configured such that the laminated surfaces 41 a of the plurality of single plates 41 constituting the cotter 40 are orthogonal to the direction in which the cotters 40 are fitted. Furthermore, at this time, the fiber direction of the plurality of single plates 41 constituting the cotter 40 is configured to be in a direction substantially orthogonal to the opposed surface 26 of the peripheral frame 20 and the lattice unit 30 forming the insertion hole 25. It is.

  Further, as shown in FIGS. 1 and 3, the plurality of cotters 40 include a frame member 32 in one lattice unit 30 in the plurality of lattice units 30 when the plurality of lattice units 30 are disposed in the frame 100. Are inserted into the insertion holes 35 formed by facing the recesses 32b of the frame member 32 in the other lattice unit 30 adjacent to the one lattice unit 30. In the present embodiment, the cross-sectional shape of the cotter 40 is substantially the same as the opening shape of the insertion hole 35, thereby preventing a gap from being opened between the cotter 40 and the insertion hole 35. However, when the gap is opened, it is desirable to fill the gap with a buried wood member made of a wooden material. The wood materials to be applied to buried members include laminated timber with several thin timbers bonded together, main timber or thinned timber, and laminated wood that has been impregnated with thermosetting resin and heat pressed. and so on.

  Here, the plurality of cotters 40 are configured such that the laminated surfaces 41 a of the plurality of single plates 41 constituting the cotter 40 are orthogonal to the direction in which the cotters 40 are fitted. Further, at this time, the fiber directions of the plurality of single plates 41 constituting the cotter 40 are such that one of the lattice units 30 in the plurality of lattice units 30 forming the insertion holes 35 and the other lattice adjacent to the one lattice unit 30. It is comprised so that it may become a direction substantially orthogonal to the opposing surface 36 with the unit 30. FIG.

  According to the seismic wall 10 configured as described above, the peripheral frame 20 disposed along the inner periphery of the frame 100, and the plurality of lattice units 30 disposed in a manner of closing the space surrounded by the peripheral frame 20; The seismic wall 10 is formed by configuring a plurality of cotters 40 as walls. Therefore, it is possible to resist the horizontal load applied to the building as the earthquake occurs.

  Moreover, according to the earthquake-resistant wall 10 comprised as mentioned above, the earthquake-resistant wall 10 is comprised using the wood material for the surrounding frame 20, the lattice unit 30, and the cotter 40. FIG. Wood material has a higher specific strength than reinforced concrete. Therefore, the seismic wall 10 using the wood material can be reduced in weight even when the same proof stress is given as compared with the reinforced concrete seismic wall. Furthermore, since the peripheral frame 20, the lattice unit 30, and the cotter 40 are configured using a wood material, a temperature difference between the members is less likely to occur than when configured using a different material for any of them. . Therefore, it is possible to suppress the occurrence of condensation on the peripheral frame 20, the lattice unit 30, and the cotter 40, and corrosion of each member due to the condensation can be prevented. In addition, since the peripheral frame 20, the lattice unit 30, and the cotter 40 are configured using a wood material, it is not necessary to perform separation according to the material when disassembling them. Moreover, since the peripheral frame 20, the lattice unit 30, and the cotter 40 are configured using a wood material, the appearance is good and the design is excellent. Furthermore, since the peripheral frame 20, the lattice unit 30, and the cotter 40 are configured using a wood material, rust does not occur in them, and there is no decrease in strength due to this.

  Furthermore, according to the seismic wall 10 configured as described above, the seismic wall 10 is configured using the wood material for the peripheral frame 20, the lattice unit 30, and the cotter 40. Wood materials have lower thermal conductivity than reinforced concrete. Therefore, in the earthquake-resistant wall 10 using a wooden material, a heat insulation effect can be heightened compared with the earthquake-resistant wall made from reinforced concrete.

  Moreover, according to the earthquake-resistant wall 10 comprised as mentioned above, the earthquake-resistant wall 10 is comprised using the some grid unit 30. FIG. Therefore, each lattice unit 30 can be reduced in size, and the work at the time of carrying the lattice unit 30 can be facilitated. Therefore, although the joining operation | work of the panel 31 and the frame material 32 can also be performed on-site, you may perform in another places, such as a factory, and can raise the freedom degree of the work accompanying construction.

  Moreover, the cotter 40 is configured to be fitted into the insertion hole 25 formed by the recess 22 of the peripheral frame 20 and the recess 32b of the frame member 32 in the lattice unit 30 facing each other. For this reason, for example, when a force is applied to move the peripheral frame 20 and the lattice unit 30 in different directions along the surface of the frame 100 with the occurrence of an earthquake, the force is also shown in FIG. In the vertical direction and the horizontal direction, the cotter 40 resists the force, and the peripheral frame 20 and the lattice unit 30 are prevented from moving. Therefore, the earthquake resistance of the building can be improved.

  Furthermore, according to the earthquake-resistant wall 10 configured as described above, in the plurality of lattice units 30, the recesses 32 b of the frame member 32 in one lattice unit 30 and the frame in the other lattice unit 30 adjacent to one lattice unit 30. The cotter 40 is configured to be fitted into the insertion hole 35 formed by facing the concave portion 32b of the material 32. For this reason, for example, with the occurrence of an earthquake, one lattice unit 30 in the plurality of lattice units 30 and the other lattice unit 30 adjacent to one lattice unit 30 are different from each other along the construction surface of the frame 100. Even when a force that moves in the direction is applied, if the force is in the vertical direction and the horizontal direction in FIG. 1, the cotter 40 resists the force, and one grid in the plurality of grid units 30. The movement of the unit 30 and the other lattice unit 30 adjacent to the one lattice unit 30 is prevented. Therefore, the earthquake resistance of the building can be improved.

  Moreover, according to the earthquake-resistant wall 10 comprised as mentioned above, it has comprised so that the lamination | stacking surface 41a of the several single board 41 which comprises the cotter 40 may be orthogonal to the direction which fits the cotter 40. FIG. Therefore, the proof stress of the cotter 40 can be increased as compared with the case where the laminated surface 41a is configured in parallel with the opposing surface 26 of the peripheral frame 20 and the lattice unit 30 that form the insertion hole 25. Further, at this time, the fiber direction of the plurality of single plates 41 constituting the cotter 40 is configured to be a direction substantially orthogonal to the facing surface 26 between the peripheral frame 20 and the lattice unit 30 forming the insertion hole 25. is there. Therefore, the proof strength of the cotter 40 can be increased compared to the case where the fiber directions of the plurality of single plates 41 constituting the cotter 40 are configured in other directions.

  Further, according to the seismic wall 10 configured as described above, the laminated surfaces 41a of the plurality of single plates 41 constituting the cotter 40 are configured to be orthogonal to the direction in which the cotter 40 is fitted. Therefore, the laminated surface 41 a is configured in parallel with the one lattice unit 30 in the plurality of lattice units 30 forming the insertion holes 35 and the facing surface 36 of the other lattice unit 30 adjacent to the one lattice unit 30. Compared with the case, the yield strength of the cotter 40 can be increased. Further, at this time, the fiber directions of the plurality of single plates 41 constituting the cotter 40 are such that one of the lattice units 30 in the plurality of lattice units 30 forming the insertion holes 35 and the other lattice adjacent to the one lattice unit 30. The unit 30 is configured to be in a direction substantially orthogonal to the facing surface 36 of the unit 30. Therefore, the proof strength of the cotter 40 can be increased compared to the case where the fiber directions of the plurality of single plates 41 constituting the cotter 40 are configured in other directions.

  However, in the present invention, the laminated surface 41a of the plurality of single plates 41 constituting the cotter 40 is not necessarily configured to be orthogonal to the direction in which the cotter 40 is fitted. For example, you may comprise so that the lamination | stacking surface 41a of the several single board 41 which comprises the cotter 40 may become in parallel with the surface of the near side of the cotter 40 in FIG.

  In the present embodiment, a plurality of cotters 40 including a plurality of single plates 41 laminated with the fiber directions aligned in substantially the same direction are illustrated, but the fiber directions do not necessarily have to be aligned in substantially the same direction. . For example, as shown in FIG. 4, it may be a plurality of cotters 40 ′ composed of a plurality of single plates 41 laminated so that the fiber directions are substantially orthogonal to each other. Furthermore, although not clearly shown in the drawing, a cotter may be used in which a plurality of single plates are laminated without defining the fiber direction, and as a result, the fiber directions are directed in irregular directions.

  Moreover, in this Embodiment, although the lattice unit 30 which joined the panel 31 and the frame material 32 only with the adhesive agent is illustrated, it does not necessarily need to join only with an adhesive agent, as shown in FIG. In addition, a plurality of reinforcing pins 60 may be used in combination. The plurality of reinforcing pins 60 are each made of a wood material and are rod-shaped members having a substantially circular cross section. The plurality of reinforcing pins 60 are fitted into a plurality of holes (not shown) provided in the panel 31 'and the frame member 32'. As a wood material applied to the reinforcing pin 60, a reinforced wood obtained by impregnating a plurality of laminated single plates with a thermosetting resin and heat-pressing is optimal. In FIG. 5, the recess of the frame member 32 ′ is omitted, but a recess is provided at a predetermined position on the outer peripheral edge of the frame member 32 ′.

  FIG. 6 shows a first modified example of the above-mentioned seismic wall. Similar to the above-described embodiment, the earthquake-resistant wall 110 of the first modification is configured in a frame 100 composed of a building column 101 and a beam 102, and a lattice unit constituting the earthquake-resistant wall is replaced with a beam. The only difference is that it extends in the extending direction and is arranged in one row in the vertical direction. Also in the earthquake-resistant wall 110 of the modification 1 comprised in this way, there can exist the same effect.

  In the first modification, the lattice unit 130 is configured by joining the panel 131 and the frame member 132 only with the adhesive. However, the lattice unit 130 may not be necessarily joined only with the adhesive. Similarly, a plurality of reinforcing pins may be used in combination. Further, in the first modification, a plurality of reinforcing members 70 may be used in combination with the lattice unit 130 as shown in FIG. The plurality of reinforcing members 70 are each made of a wood material and are substantially rectangular plate-like members. The plurality of reinforcing members 70 are appropriately interposed between the frame members 132 in the openings 132 a of the frame member 132. Even in this case, a plurality of reinforcing pins may be used in combination for joining the panel 131 and the frame member 132. In FIG. 7, the recess of the frame member 132 is omitted, but the recess is provided at a predetermined position on the outer peripheral edge of the frame member 132.

  FIG. 8 shows a second modification of the above-mentioned earthquake resistant wall. The seismic wall 210 of this modified example 2 is constructed in the frame 100 composed of the pillars 101 and the beams 102 of the building, as in the above-described embodiment and modified example 1, and is a lattice that constitutes the seismic wall. The unit is elongated in the vertical direction and is configured in a line in the extending direction of the beam, the lattice unit is provided with a protrusion and a fitting groove, one lattice unit of the plurality of lattice units, The only difference is that no cotter is interposed between the other lattice unit adjacent to the other lattice unit. Note that in the second modification, the same reference numerals are given to the same configurations as those in the embodiment, and detailed descriptions thereof are omitted.

  Each of the plurality of lattice units 230 is made of a wood material, and is arranged in a manner to close a space surrounded by the peripheral frame 20. The plurality of lattice units 230 include a panel 231 and a frame member 232, respectively, as shown in FIGS.

  The panel 231 is a substantially rectangular plate material. As a wood material applied to the panel 231, a reinforced wood in which a plurality of laminated single plates are impregnated with a thermosetting resin and hot pressed is optimal. In this embodiment, the panel 231 employs reinforced wood using a phenol resin as a thermosetting resin.

  In FIG. 9A, the frame member 232 is for fitting and holding the upper and lower peripheral edges of the panel 231, and is configured to form the protruding portion 231 a and the fitting groove 237 when fitted and held. . The frame member 232 is provided with an opening 232a and a plurality of recesses (not shown). The opening 232a is a substantially rectangular opening. The plurality of recesses (not shown) are grooves that open toward the outside of the frame member 232, and are disposed at predetermined positions on the outer peripheral edge of the frame member 232. The plurality of recesses (not shown) are configured to face the recesses 22 of the peripheral frame 20 when the frame member 232 is disposed in the frame 100. The wood material to be applied to the frame material 232 includes laminated lumber obtained by bonding several thin sheets of wood, main felled or thinned lumber, and a plurality of laminated single plates impregnated with thermosetting resin and reinforced by hot pressing There are trees. In the present embodiment, reinforced wood using a phenol resin as a thermosetting resin is employed for the frame member 232. In FIG. 9A, the recess of the frame member 232 is omitted, but the recess is provided at a predetermined position on the outer peripheral edge of the frame member 232.

  Although not explicitly shown in the drawing, the panel 231 and the frame member 232 are bonded with an adhesive. An appropriate amount of this adhesive is applied to a portion that comes into contact when the panel 231 is fitted to the frame member 232.

  As is clear from FIG. 10, one lattice unit 230 in the plurality of lattice units 230 and the other lattice unit 230 adjacent to the one lattice unit 230 include the protrusions 231 a and the fitting grooves 237. It is fitted. By fitting in this way, it becomes easy to arrange a plurality of lattice units 230.

  Also in the seismic wall 210 of this modified example 2, the peripheral frame 20 disposed along the inner periphery of the frame 100, the plurality of lattice units 230 disposed in a manner of closing the space surrounded by the peripheral frame 20, By constructing the cotter 40 as a wall, the seismic wall 210 is formed. Therefore, it is possible to resist the horizontal load applied to the building as the earthquake occurs.

  Also in the seismic wall 210 of the second modification, the seismic wall 210 is configured by using a wood material for the peripheral frame 20, the lattice unit 230 and the cotter 40. Wood material has a higher specific strength than reinforced concrete. Therefore, the seismic wall 210 using the wood material can be reduced in weight even when the same proof stress is given as compared with the reinforced concrete seismic wall. Furthermore, since the peripheral frame 20, the lattice unit 230, and the cotter 40 are configured using a wood material, a temperature difference between the members is less likely to occur than when configured using a different material for any of them. . Therefore, it is possible to suppress the occurrence of condensation on the peripheral frame 20, the lattice unit 230, and the cotter 40, and corrosion of each member due to the condensation can be prevented. In addition, since the peripheral frame 20, the lattice unit 230, and the cotter 40 are configured using a wood material, it is not necessary to perform separation according to the material when disassembling them. Moreover, since the peripheral frame 20, the lattice unit 230, and the cotter 40 are configured using a wood material, the appearance is good and the design is excellent. Further, since the peripheral frame 20, the lattice unit 230, and the cotter 40 are made of a wood material, they are not rusted, and the strength is not reduced.

  Furthermore, also in the earthquake-resistant wall 210 of this modification 2, the earthquake-resistant wall 210 is comprised using the wood material for the surrounding frame 20, the lattice unit 230, and the cotter 40. Wood materials have lower thermal conductivity than reinforced concrete. Therefore, in the earthquake-resistant wall 210 using a wooden material, the heat insulation effect can be enhanced as compared with the earthquake-resistant wall made of reinforced concrete.

  Also in the earthquake-resistant wall 210 of the second modification, the earthquake-resistant wall 210 is configured using a plurality of lattice units 230. Therefore, each lattice unit 230 can be reduced in size, and the work at the time of carrying the lattice unit 230 can be facilitated. Therefore, the joining operation of the panel 231 and the frame member 232 can be performed on site, but it may be performed in another place such as a factory, and the degree of freedom of work accompanying construction can be increased.

  In addition, the cotter 40 is fitted into an insertion hole (not shown) formed by the recess 22 of the peripheral frame 20 and the recess (not shown) of the frame member 232 in the lattice unit 230 facing each other. It is configured. Therefore, for example, when a force is applied to move the peripheral frame 20 and the lattice unit 230 in different directions along the construction surface of the frame 100 with the occurrence of an earthquake, the force is also shown in FIG. In the vertical direction and the horizontal direction, the cotter 40 resists the force, and the peripheral frame 20 and the lattice unit 230 are prevented from moving. Therefore, the earthquake resistance of the building can be improved.

  In the second modification, the panel 231 and the frame member 232 are joined only with an adhesive to form the lattice unit 230. However, the lattice unit 230 may not necessarily be joined only with the adhesive. Similar to the first modification, a plurality of reinforcing pins may be used in combination. Further, in the second modification, similarly to the first modification, the lattice unit 230 may be configured by using a plurality of reinforcing members in combination. Also in this case, a plurality of reinforcing pins may be used in combination for joining the panel 231 and the frame member 232.

  Further, in the second modification, the lattice unit 230 in which the upper and lower peripheral edges of the panel 231 are fitted and held in FIG. 9A with the frame member 232 is illustrated, but the fitting may not necessarily be held. For example, as shown in FIGS. 11A and 11B, a lattice unit 230 ′ configured to sandwich a panel 231 ′ between a pair of frame members 232 ′ and 233 ′ may be used. In this case, it is necessary to provide a recess in the panel 231 ′ so as to correspond to a recess (not shown) of the pair of frame members 232 ′ and 233 ′. In FIG. 11A, the recesses of the pair of frame members 232 'and 233' are omitted, but the recesses are provided at predetermined positions on the outer peripheral edges of the pair of frame members 232 'and 233'.

  Further, in the second modification, the projection 231a and the fitting groove 237 are formed when the frame material 232 is fitted and held. However, the projection 231a and the fitting groove 237 are not necessarily provided. Also good. Moreover, when providing the protrusion part 231a and the fitting groove 237 and fitting, you may apply | coat an appropriate amount of adhesives to the part to contact. Furthermore, when providing the protrusion part 231a and the fitting groove 237 and fitting, you may use a some reinforcement pin (not shown). The plurality of reinforcing pins (not shown) are each made of a wood material and are rod-like members having a substantially circular cross section. The plurality of reinforcing pins (not shown) are desirably configured in a manner of penetrating vertically in the fitting portion between the protruding portion 231a and the fitting groove 237 in FIG. As a wood material to be applied to the reinforcing pin, a reinforced wood obtained by impregnating a plurality of laminated single plates with a thermosetting resin and heat-pressing is optimal.
