  By the way, as a reinforcement structure of a frame, it is conceivable to provide a wooden wall in the surface of the frame and join the wooden wall to the frame.

  However, the joint between the wooden wall and the frame is easily damaged as compared with the RC wall or the steel wall. Therefore, it is difficult to sufficiently transmit the seismic force between the frame and the wooden wall, and there is a possibility that the reinforcing efficiency of the frame is reduced.

  SUMMARY OF THE INVENTION An object of the present invention is to increase the efficiency of reinforcing a frame in consideration of the above fact.

  The frame reinforcement structure according to claim 1, wherein the frame includes a pair of columns, and upper and lower horizontal members that are mounted on the pair of columns, and provided at corners of the frame at opposite corners, respectively. A pair of diagonal members installed between the pair of diagonal members and the horizontal member; and a wooden wall provided between the pair of diagonal members, the diagonal members being in surface contact with end surfaces.

  According to the frame reinforcing structure of the first aspect, the frame includes the pair of columns and the upper and lower horizontal members installed on the pair of columns. Also, diagonal members are provided at the corners of the frame at opposite corners. The diagonal member is erected between the column and the horizontal member. Thereby, the rigidity of the frame is increased.

  In addition, a wooden wall is provided between the pair of diagonal members. A pair of diagonal members are in surface contact with the end surface of the wooden wall. Thus, when the distance between the pair of diagonal members becomes narrow due to the shear deformation of the frame during the earthquake, seismic force is transmitted from the pair of diagonal members to the end face of the wooden wall.

  Here, as described above, the pair of diagonal members are in surface contact with the end surface of the wooden wall. Thus, when the distance between the pair of diagonal members is reduced due to the shear deformation of the frame during an earthquake, the seismic force is efficiently transmitted from the pair of diagonal members to the end face of the wooden wall as a compressive force.

  As described above, in the present invention, it is possible to efficiently transmit the seismic force as a compressive force from the pair of diagonal members to the end face of the wooden wall while increasing the rigidity of the frame by the pair of diagonal members. Therefore, the efficiency of reinforcing the frame can be increased.

  A frame reinforcement structure according to a second aspect is the frame reinforcement structure according to the first aspect, further comprising a tension member that joins the diagonal member and the wooden wall.

  According to the frame reinforcing structure of the second aspect, the diagonal member and the wooden wall are joined by the tensile member. Thereby, when the interval between the pair of diagonal members is widened due to the shear deformation of the frame during an earthquake, the tensile force is transmitted from the pair of diagonal members to the wooden wall via the tensile members. Therefore, the reinforcement efficiency of the frame can be further increased.

  The frame reinforcing structure according to claim 3 is the frame reinforcing structure according to claim 1 or 2, wherein a reinforcing member is provided in a space defined by the pillar, the horizontal member, and the diagonal member. .

  According to the frame reinforcing structure of the third aspect, the reinforcing member is provided in the space defined by the columns, the horizontal members, and the diagonal members. By reinforcing the diagonal members with this reinforcing material, the rigidity of the frame is further increased. Further, when the distance between the pair of diagonal members becomes narrow due to the shear deformation of the frame during the earthquake, the seismic force is more efficiently transmitted from the diagonal members to the end face of the wooden wall. Therefore, the reinforcement efficiency of the frame can be further increased.

  As described above, according to the frame reinforcement structure of the present invention, the reinforcement efficiency of the frame can be increased.

Thereby, the end of the beam 14 is pin-joined to the connection 12J of the column 12.

  The joining structure between the column 12 and the beam 14 can be appropriately changed. For example, the end of the beam 14 may be rigidly joined to the connection 12J of the column 12. Further, the column 12 and the beam 14 are not limited to the H-shaped steel, and may be another shaped steel or a steel pipe.

(Slanting material)
As shown in FIG. 1, the diagonal members 30 are provided at four corners 10K1 and 10K2 of the frame 10, respectively. Each diagonal member 30 increases the rigidity (shear rigidity) of the frame 10 and functions as a seismic force transmitting unit that transmits seismic force to the wooden wall 40 described later. Specifically, each diagonal member 30 is formed in a plate shape by a steel plate or the like. These diagonal members 30 are arranged in pairs at corners 10K1 and 10K2 of the frame 10 at opposite corners.

  In the following, a pair of diagonal members 30X provided at one diagonal corner 10K1 and 10K2 is referred to as a pair of diagonal members 30X, and a pair of diagonal members provided at the other diagonal corners 10K1 and 10K2. In some cases, the description will be made by distinguishing 30 as a diagonal member 30Y. In the present embodiment, the pair of diagonal members 30X and the pair of diagonal members 30Y have the same configuration. Therefore, hereinafter, the configuration of the pair of diagonal members 30X will be described, and the description of the configuration of the pair of diagonal members 30Y will be appropriately omitted.

  As shown in FIG. 2, one of the diagonal members 30X of the pair of diagonal members 30X is installed diagonally between the column 12 and the beam 14 at the upper corner 10K1 (upper corner) of the frame 10. . Specifically, the diagonal member 30X is arranged at the upper corner 10K1 in a state of being inclined with respect to the column 12 and the beam 14. One end (lower end) of the diagonal member 30X is joined to the beam 14 side of the inner side surface 12S of the column 12 by welding or the like. The other end (upper end) of the diagonal member 30X is joined to the column 12 on the lower surface 14L of the beam 14 by welding or the like. By connecting the column 12 and the beam 14 with the diagonal member 30X, the rigidity of the joint (pin joint) between the column 12 and the beam 14 is increased. The diagonal member 30X defines a triangular space 32 together with the columns 12 and the beams 14.

  As shown in FIG. 1, the other diagonal member 30 </ b> X of the pair of diagonal members 30 </ b> X is installed diagonally between the pillar 12 and the beam 14 at the lower corner 10 </ b> K 2 (lower corner) of the frame 10. . Specifically, the diagonal member 30X is arranged at the lower corner 10K2 so as to be inclined with respect to the column 12 and the lower beam 14. One end (upper end) of the diagonal member 30X is joined to the beam 14 side on the inner side surface 12S of the column 12 by welding or the like. The other end (lower end) of the diagonal member 30X is joined to the column 12 on the upper surface 14U of the beam 14 by welding or the like. By connecting the column 12 and the beam 14 with the diagonal member 30X, the rigidity of the joint (pin joint) between the column 12 and the beam 14 is increased. The diagonal member 30X defines a triangular space 32 together with the columns 12 and the beams 14.

  As shown in FIG. 2, the pair of diagonal members 30X has a contact surface 30T that is inclined at a predetermined inclination angle θ with respect to the column 12 (the direction of the material axis of the column 12). The contact surface 30T is inclined at, for example, 40 ° to 50 ° with respect to the column 12 (40 ° ≦ θ ≦ 50 °). Further, a through hole 34 into which a bolt member 50 described later is inserted is formed in the diagonal member 30X. Note that the inclination angle θ of the contact surface 30T is preferably 40 ° to 50 °, and more preferably about 45 °.

  An octagonal opening 36 defined by a pair of columns 12, upper and lower beams 14, a pair of diagonal members 30X, and a pair of diagonal members 30Y is formed in the center of the frame 10. A wooden wall 40 is provided in the opening 36. Note that the inner peripheral surface of the opening 36 is formed by the inner side surfaces 12S of the pair of pillars 12, the lower surface 14L of the upper beam 14, the upper surface 14U of the lower beam 14, and the contact surface 30T between the diagonal members 30X and 30Y. .

(Wooden wall)
The wooden wall 40 is provided in the surface of the frame 10 and functions as an earthquake-resistant wall or a load-bearing wall. The wooden wall 40 is formed into a wall shape by using a wooden surface material (a wooden panel material) such as a CLT (Cross Laminated Timber), an LVL (Laminated Veneer Lumber), a laminated timber, and a plywood.

  The wooden wall 40 is formed in an octagonal shape in a front view according to the shape of the opening 36 of the frame 10. The wooden wall 40 is fitted in the opening 36 of the frame 10, and is disposed between the pair of diagonal members 30X and between the pair of diagonal members 30Y.

  The wooden wall 40 has left and right side end surfaces 40S, upper and lower upper end surfaces 40U and lower end surfaces 40L, and corner end surfaces 40C at each corner. The side end surface 40S of the wooden wall 40 is arranged along the inner side surface 12S of the pillar 12. The side end surface 40S of the wooden wall 40 and the inner side surface 12S of the column 12 are not joined and can be relatively displaced during an earthquake. The upper end surface 40U of the wooden wall 40 is arranged along the lower surface 14L of the upper beam 14. The upper end surface 40U of the wooden wall 40 and the lower surface 14L of the upper beam 14 are not joined and can be relatively displaced. Similarly, the lower end surface 40L of the wooden wall 40 is arranged along the upper surface 14U of the lower beam 14. The lower end surface 40L of the wooden wall 40 and the upper surface 14U of the lower beam 14 are not joined and can be relatively displaced during an earthquake.

  The corner end surface 40C of the wooden wall 40 is joined to the diagonal member 30 in a state of being in surface contact with the contact surface 30T of the diagonal member 30X, that is, in a state of being superimposed on the contact surface 30T of the diagonal member 30X. Specifically, as shown in FIG. 2, two bolt members 50 such as lag screw bolts are embedded in the corners of the wooden wall 40 so as not to protrude from the corner end surface 40C.

  A screw hole 52 is formed in the head of each bolt member 50. By screwing the bolts 38 into the screw holes 52 through the through holes 34 of the diagonal member 30X, the contact surfaces 30T of the diagonal member 30X are joined to the corner end surfaces 40C in a state of surface contact. Further, the diagonal member 30X and the wooden wall 40 are joined by the bolt member 50 so that the tensile force can be transmitted.

  The corner end surface 40C of the wooden wall 40 and the contact surface 30T of the diagonal member 30X may be in direct surface contact, or may be indirectly in contact via another member such as a sheet material or a plate material. May be. The bolt member 50 is an example of a tensile member.

(Action)
Next, the operation of the present embodiment will be described.

  As shown in FIG. 1, according to the frame reinforcement structure 20 according to the present embodiment, a pair of diagonal members 30X is provided at one of the diagonal corners 10K1 and K2 of the frame 10 and diagonally formed. A pair of diagonal members 30Y is provided at the other corners 10K1 and K2. Each of the diagonal members 30X and 30Y is installed diagonally between the column 12 and the beam 14 at the corners 10K1 and 10K2 of the frame 10. Thereby, the rigidity (shear rigidity) of the frame 10 is increased.

  In addition, by increasing the rigidity of the frame 10 by the diagonal members 30X and 30Y, the columns 12 and the beams 14 can be joined by easy pin joining. Therefore, the workability of the joint between the column 12 and the beam 14 is improved.

  Further, a wooden wall 40 is provided between the pair of diagonal members 30X and between the pair of diagonal members 30Y. The contact surface 30T of the diagonal 30X or the diagonal 30Y is in surface contact with a corner end surface 40C of each corner of the wooden wall 40. Thereby, for example, as shown by an arrow L in FIG. 1, when the interval between the pair of diagonal members 30X becomes narrow due to the shear deformation of the frame 10 during an earthquake, the contact surface 30T of the pair of diagonal members 30X. Then, the seismic force is transmitted to the corner end face 40C of the wooden wall 40, and the compression strut P is generated on the wooden wall 40. The seismic force is transmitted between the diagonal connection portions 12J of the frame 10 by the compression struts P.

  Here, as described above, the contact surfaces 30T of the pair of diagonal members 30X are in surface contact with the corner end surfaces 40C of the wooden wall 40, respectively. Accordingly, when the interval between the pair of diagonal members 30X is reduced due to the shear deformation of the frame 10 during an earthquake, seismic force is compressed from the contact surface 30T of the pair of diagonal members 30X to the corner end surface 40C of the wooden wall 40. It is transmitted efficiently as power.

  Similarly, as shown by an arrow R in FIG. 1, when the distance between the pair of diagonal members 30 </ b> Y is reduced due to the shear deformation of the frame 10 during an earthquake, the contact surface 30 </ b> T between the pair of diagonal members 30 </ b> Y is used. The seismic force is efficiently transmitted to the corner end surface 40C of the wooden wall 40 as a compressive force.

  As described above, in the present embodiment, the seismic force is efficiently transmitted as a compressive force from each of the diagonal members 30X, 30Y to the corner end face 40C of the wooden wall 40 while increasing the rigidity of the frame 10 by each of the diagonal members 30X, 30Y. Can be. Therefore, the reinforcing efficiency of the frame 10 can be increased.

  The diagonal members 30X and 30Y are joined to the wooden wall 40 by bolt members 50 so that a tensile force can be transmitted. Thereby, for example, as shown by an arrow L in FIG. 1, when the interval between the pair of diagonal members 30Y is widened due to the shear deformation of the frame 10 during an earthquake, the bolt member 50 is removed from the pair of diagonal members 30Y. The tensile force F is transmitted to the wooden wall 40 via the.

  Similarly, as shown by an arrow R in FIG. 1, when the distance between the pair of diagonal members 30X increases due to the shear deformation of the frame 10 during an earthquake, the bolt member 50 is removed from the pair of diagonal members 30X. The tensile force is transmitted to the wooden wall 40 via the. Therefore, the reinforcing efficiency of the frame 10 can be further increased.

  Here, as a comparative example, without providing the frame 10 with the diagonal members 30X and 30Y, a rectangular wooden wall is provided in the front surface of the frame 10 in a front view, and the left and right side end surfaces of the wooden wall are paired with a pair of pillars. It is conceivable that the upper end surface and the lower end surface of the wooden wall are joined to the upper and lower beams 14 by bolt members, respectively, while being joined to the upper and lower beams 12 by bolt members.

  However, in this case, when the frame 10 is sheared and deformed, a shear force along the material axis direction of the column 12 or the beam 14 acts on the bolt member, and the bolt member may be broken. Further, it is conceivable to increase the number of bolt members so as not to break the bolt members, but in this case, it takes time and labor to construct the bolt members.

  On the other hand, in the present embodiment, the diagonal members 30X and 30Y and the wooden wall 40 are joined by the bolt members 50. The contact surfaces 30T of the diagonal members 30X and 30Y and the corner end surface 40C of the wooden wall 40 are inclined at a predetermined inclination angle θ with respect to the column 12. Thereby, the shearing force acting on the bolt member 50 is reduced.

  Further, when the frame 10 undergoes shear deformation, the seismic force transmitted from the pair of diagonal members 30X to the wooden wall 40 is transmitted, for example, in a direction of approximately 45 ° to the column 12. By adjusting the inclination angle θ of the contact surface 30T of the diagonal member 30X and the corner end surface 40C of the wooden wall 40 to, for example, 45 ° (θ = 45 °) so as to be substantially orthogonal to the direction of transmission of the seismic force, the bolt member is formed. The shear force acting on 50 is further reduced. Therefore, the breakage of the bolt member 50 is suppressed.

  In the present embodiment, the seismic force (compressive force and tensile force) is transmitted between the diagonal member 30 and the wooden wall 40. Therefore, the side end surface 40S, the upper end surface 40U, and the lower end surface 40L of the wooden wall 40 and the columns 12 and the beams 14 can be non-joined. Therefore, the workability of the wooden wall 40 is improved.

(Modification)
Next, a modified example of the above embodiment will be described.

<First modification>
In the first modified example shown in FIG. 3, a reinforcing plate 60 for reinforcing the diagonal member 30 is provided in a triangular space 32 defined by the columns 12, the beams 14, and the diagonal member 30 at the corner 10 </ b> K 1 of the frame 10. Is provided. The reinforcing plate 60 is an example of a reinforcing material.

  The reinforcing plate 60 is formed of a steel plate or the like. Further, the reinforcing plate 60 is formed in a triangular shape corresponding to the shape of the space 32 described above, and is fitted into the space 32. The outer peripheral portion of the reinforcing plate 60 is joined to the inner surface 12S of the column 12, the lower surface 14L of the beam 14, and the outer surface 30G of the diagonal member 30 by welding or the like. The diagonal member 30X is reinforced (stiffened) by the reinforcing plate 60.

  By reinforcing the diagonal member 30X with the reinforcing plate 60 in this manner, the rigidity (shear rigidity) of the frame 10 is further increased. Further, when the frame 10 undergoes shear deformation during an earthquake, the seismic force (compressive force and tensile force) is more efficiently transmitted between the diagonal member 30 and the wooden wall 40. Therefore, the reinforcing efficiency of the frame 10 can be further increased.

  The reinforcing plate 60 is not limited to welding, and may be joined to the column 12, the beam 14, and the diagonal member 30 by, for example, bolts. Further, the reinforcing plate 60 can be joined to at least one of the column 12, the beam 14, and the diagonal member 30. Further, the shape of the reinforcing plate 60 can be appropriately changed.

<Second modification>

The column flange 70 and the diagonal member 30X are formed of a steel plate or the like.

  The pillar side flange portion 70 protrudes from the inner side surface 12S of the pillar 12. A flange 14A below the beam 14 is placed on the upper surface of the column flange 70. The column side flange portion 70 and the flange portion 14A below the beam 14 are joined by a bolt 72 and a nut 73.

  The diagonal member 30X is arranged below the column-side flange portion 70. In addition, the diagonal member 30 </ b> X is installed diagonally between the tip of the column-side flange portion 70 in the projecting direction and the inner side surface 12 </ b> S of the column 12. The corner surface 40C of the wooden wall 40 is joined to the contact surface 30T of the diagonal member 30X by the bolt member 50. The diagonal member 30X defines a triangular space 76 together with the column side flange 70 and the column 12. In this space 76, a reinforcing plate 60 is provided.

  As described above, in the present modified example, the column 12 is provided with the column side flange portion 70 and the diagonal member 30X in advance. Thus, the end of the beam 14 can be joined to the connection 12 </ b> J of the column 12 in a state where the beam 14 is placed on the column side flange portion 70. Therefore, the workability of the beam 14 is improved.

  Further, by joining the column side flange portion 70 to the flange portion 14A below the beam 14 with the bolt 72 and the nut 73, the diagonal member 30X can be easily joined to the beam 14.

  Further, by providing the pillar 12 with the diagonal member 30X in advance, the beam 14 can be constructed after attaching the wooden wall 40 to the pillar 12. Therefore, the workability of the wooden wall 40 is improved as compared with the case where the wooden wall 40 is installed (transversely inserted) on the surface of the frame 10 after the column 12 and the beam 14 are joined.

  Note that the wooden wall 40 may be installed on the surface of the frame 10 after joining the pillar 12 and the beam 14. Further, the column side flange portion 70 and the flange portion 14A below the beam 14 are not limited to the bolt 72 and the nut 73, but may be joined by welding or the like.

<Third modification>
Next, in a third modified example shown in FIG. 6, the diagonal member 30X is integrated with the beam 14 in advance. Specifically, the lower surface 14L of the beam 14 is provided with a diagonal member 30X, a reinforcing plate 60, and a beam-side flange portion 80.

  The beam-side flange portion 80 is formed of a steel plate or the like, and is attached to the lower surface 14L of the beam 14 via the diagonal member 30X and the reinforcing plate 60. The beam-side flange portion 80 extends downward from the beam 14. The beam side flange portion 80 is joined to the column 12 by bolts 82 and nuts 84 in a state where the beam side flange portion 80 is overlaid on the inner side surface 12S of the column 12.

  The diagonal member 30X is disposed below the beam 14. In addition, the diagonal member 30 </ b> X is installed diagonally between the front end (lower end) of the beam-side flange portion 80 in the projecting direction and the lower surface 14 </ b> L of the beam 14. The corner surface 40C of the wooden wall 40 is joined to the contact surface 30T of the diagonal member 30X by the bolt member 50. The diagonal member 30X defines a triangular space 86 together with the beam-side flange portion 80 and the beam 14. The reinforcing plate 60 is provided in the space 86.

  By providing the beam 14 with the diagonal member 30X in advance, the beam 14 and the wooden wall 40 can be integrally built with the beam 14 attached to the wooden wall 40. Therefore, the workability of the wooden wall 40 is improved.

  The beam 14 is provided with a beam-side flange portion 80 in advance. By joining the beam-side flange portion 80 to the flange portion 12A of the column 12 with a bolt 82 and a nut 84, one end of the diagonal member 30X can be easily attached to the column 12 via the beam-side flange portion 80.

  Note that the wooden wall 40 can be installed (transversely inserted) on the surface of the frame 10 after joining the pillar 12 and the beam 14. Further, the beam side flange portion 80 and the flange portion 12A of the column 12 are not limited to the bolts 82 and the like, but may be joined by welding or the like.
