As shown in FIGS. 2 and 3, the shear reinforcing structure portion 10 is provided straddling the upper horizontal member 4, the beam 6, and the reinforcing frame member 7 located at the uppermost position, and has a horizontal shear force as described above. On the other hand, the framework structure 1 is reinforced.
Such a shear reinforcing structure portion 10 has a panel body 100, a thickness adjusting material 101, and a connecting plate 102.

The panel body 100 includes a rectangular frame body 100a made of vertical and horizontal frame members, a reinforcing vertical bar member 100b provided in the center of the frame body 100a, and a vertical frame member and a reinforcing vertical bar member 100b in the frame body 100a. A plurality of frame reinforcing materials 100c provided between the upper and lower ends, a small panel 100d provided at a position surrounded by a frame body 100a, a reinforcing vertical crosspiece 100b, and a plurality of frame reinforcing materials 100c, and a panel. A face material 100e provided on the front surface and the back surface of the body 100 is provided.
The width dimension (dimension in the left-right direction) of the panel body 100 takes into consideration the lateral overhanging dimension of the support member 5 which is a dougong (see FIG. 1). Further, the thickness dimension (dimension in the front-back direction) of the panel body 100 is equal to the dimension in the front-back direction in the upper horizontal member 4.
Such a panel body 100 has extremely high rigidity as wood, and is extremely difficult to be deformed even when it receives an external force.

In the frame body 100a, the lower horizontal frame member is fixed to the upper horizontal frame member 4, and the upper horizontal frame member is fixed to the beam 6.
The frame body 100a and the reinforcing vertical crosspiece 100b are preferably, but are not limited to, in a pre-assembled state.
The plurality of frame reinforcing members 100c are provided as reinforcement against the horizontal shearing force applied to the frame body 100a and the reinforcing vertical crosspiece 100b.
The small panel 100d is composed of a rectangular frame body made of vertical and horizontal frame members, and face materials attached to the front and back surfaces of the frame body.
The face material 100e is, for example, a structural plywood, and is fixed to the front and back surfaces of the frame body 100a, the reinforcing vertical crosspiece 100b, the frame reinforcing material 100c, and the small panel 100d by fixing tools such as screws. Has been done. The face material 100e is not limited to the fixing tool, but may be an adhesive or may be used in combination with an adhesive.

The thickness adjusting material 101 is a wooden plate material fixed to the front surface and the back surface of the reinforcing frame material 7 located at the uppermost position. Since the dimension in the front-back direction of the reinforcing frame material 7 is shorter than the dimension in the front-back direction of the upper horizontal member 4, the thickness is adjusted by the thickness adjusting material 101.
The surface of the thickness adjusting material 101 fixed to the front surface and the back surface of the reinforcing frame material 7 and the surface (front surface and back surface) of the upper horizontal member 4 are flush with each other.

As a set of four connecting plates 102, the panel body 100, the upper horizontal member 4, and the reinforcing frame member 7 located at the uppermost position are formed at both ends in the width direction on the front side and the back side of the shear reinforcing structure portion 10. It is provided across.
A set of four connecting plates 102 is fixed to the panel body 100, the upper horizontal member 4, and the reinforcing frame member 7 located at the uppermost position by a fixing tool such as a screw. That is, the reinforcing frame material 7 located at the uppermost position to the beam 6 are firmly connected.
Further, since the connecting plates 102 are provided in a set of four in this way, even if the upper end portion of the framework structure 1 including the shear reinforcing structure portion 10 tries to operate in a complicated manner due to the horizontal shearing force, the connecting plate 102 may operate in a complicated manner. The operation can be surely suppressed.

Although not shown, the shear reinforcing structure portion 10 may be covered with a panel material different from the panel material 11 described above.
That is, since the panel material 11 is arranged between the existing pillar materials 2 adjacent to each other, the upper end surface is provided in a state of being in contact with the lower end surface of the thickness adjusting material 101 and the connecting plate 102. In that case, since the shear reinforcing structure portion 10 cannot be covered with the panel material 11, a separate panel material is used for the shear reinforcement structure portion 10 (and the upper half portion at both ends of the reinforcing frame material 7 located at the uppermost position). Cover.

The scale of each dimension setting in the framework structure 1 including the reinforcing frame material 7 and the reinforcing material 9 may be appropriately changed according to the size of the wooden building requiring reinforcement. In that case, structural calculation shall be performed as appropriate.

Next, a construction method of the framework structure 1 configured as described above (a method of repairing the existing framework structure 1) will be described.

It is assumed that the frame body 100a and the reinforcing vertical crosspiece 100b of the panel body 100 in the shear reinforcing structure portion 10 are assembled in advance. Further, when the frame body 100a is not screwed to the upper horizontal member 4 and the beam 6, the panel body 100 itself may be assembled in advance.

The existing frame structure 1 before the repair is in the state shown in FIG. 1. First, a plurality of joining rods 8 are attached to the adjacent column members 2 of the frame structure 1 by a tool such as a drill. The same number of insertion holes 2a for joining are formed.

Subsequently, the joining rod 8 is inserted into each of the plurality of joining insertion holes 2a in the adjacent pillars 2.
Then, among the adjacent pillars 2, the reinforcing frame material 7 is attached to the plurality of joining rods 8 inserted into the plurality of joining insertion holes 2a in the left pillar 2 (may be the right pillar 2). Temporarily attach the first split body 70. That is, the first divided body is in a state in which the plurality of joining rods 8 protruding from the left pillar material 2 are inserted into the plurality of joining insertion holes 7a formed in the first divided body 70. Temporarily attach 70. In this state, the first divided body 70 is not fixed at all, and moreover, as described above, the joining rod 8 and the joining insertion hole 2a on the pillar 2 side and the joining on the reinforcing frame 7 side are joined. Since there is a gap between the insertion hole 7a and the insertion hole 7, the first divided body 70 can be tilted in the vertical direction or the vertical direction.

Subsequently, as shown by the arrow Y1 in FIG. 5, the first divided body 70 is tilted toward the back side to be displaced from the center, and then the second divided body 71 is moved to the right column as shown by the arrow Y2. Temporarily attached to a plurality of joining rods 8 inserted into the plurality of joining insertion holes 2a in the material 2. That is, the second divided body is in a state in which the plurality of joining rods 8 protruding from the pillar material 2 on the right side are inserted into the plurality of joining insertion holes 7a formed in the second divided body 71. Temporarily attach 71.
Then, the notches at the central end portions of the first divided body 70 and the second divided body 71 are made to match. In other words, the notches of each other are matched in the same way as a joint.

In the case of the first divided body 70 in which the central side end portion is cut out in an L shape, the portion of the central side end portion remaining without being cut out is located on the back side. In this case, the first divided body 70 Is tilted toward the back side, so that a space for temporarily attaching the second split body 71 can be secured. On the other hand, if the first divided body 70 is tilted toward the front side, the portion of the first divided body 70 that remains without being cut off interferes with the central end portion of the second divided body 71. It becomes difficult to temporarily attach the split body 71.
That is, in the case of matching the central end portion of the first split body 70 with the central side end portion of the second split body 71 in the manner of a phase-jamming joint, the split body temporarily attached first (FIG. 5). Then, by tilting the first divided body 70) in the direction opposite to the cutout side, a space for temporary attachment of the divided body (the second divided body 71 in FIG. 5) to be temporarily attached later is created. It can be secured.
Further, if the gap formed between the plurality of joining rods 8 and the joining insertion holes 2a and 7a on the pillar material 2 side and the reinforcing frame material 7 side is too narrow, the one temporarily attached first. The angle at which the split body is tilted becomes smaller, and the angle at which the split body to be temporarily attached later is temporarily attached also becomes narrower. Therefore, a gap formed between the plurality of joining rods 8 and the joining insertion holes 2a and 7a on the pillar 2 side and the reinforcing frame material 7 side (diameters of the joining insertion holes 2a and 7a). Considers the angle at which the split body temporarily attached first is tilted and the angle at which the split body temporarily attached later is temporarily attached.

After matching the notches of the first divided body 70 and the second divided body 71 with each other, the first divided body 70 and the second divided body 71 are joined (in the present embodiment, joining with an adhesive).
After the plurality of reinforcing frame members 7 are temporarily attached between the adjacent column members 2 by the method as described above, the joining insertion holes 2a on the column member 2 side and the joining insertion holes on the reinforcing frame member 7 side are inserted. Each of the holes 7a is filled with an adhesive. The adhesive is filled by forming injection holes (not shown) in the pillar 2 and / and the reinforcing frame material 7. Since it is desirable that the injection hole is formed at a position that is as inconspicuous as possible, in the present embodiment, the injection hole is formed on the reinforcing frame material 7 side covered with the panel material 11, and the pillar material is formed from the injection hole. Both the joining insertion hole 2a on the 2 side and the joining insertion hole 7a on the reinforcing frame material 7 side are filled with an adhesive.

Subsequently, the plurality of reinforcing materials 9 are arranged between the plurality of adjacent reinforcing frame materials 7 at intervals above and below, and are arranged along the inner side surface (side surface of the reinforcing frame material 7) of the pillar material 2. .. Further, it is adhesively joined to the column member 2 and the reinforcing frame member 7.

Subsequently, the frame body 100a and the reinforcing vertical bar member 100b of the panel body 100 in the shear reinforcing structure portion 10 are fixed to the upper horizontal member 4 and the beam 6. Further, a plurality of frame reinforcing members 100c and small panels 100d are incorporated into the frame body 100a, and the face material 100e is attached and fixed to the front surface and the back surface of the frame body 100a.
Subsequently, the thickness adjusting material 101 is attached to and fixed to the front surface and the back surface of the reinforcing frame material 7 located at the uppermost position, and then the plurality of connecting plates 102 are positioned at the uppermost position with the panel body 100 and the upper horizontal member 4. It is provided so as to straddle the reinforcing frame material 7. As a result, the reinforcing frame material 7 located at the uppermost position to the beam 6 can be firmly connected.

After that, as shown in FIG. 3, the panel material 11 is arranged between the adjacent pillar materials 2 and joined to the front and back surfaces (front side and back side) of the plurality of reinforcing frame materials 7 and the plurality of reinforcing materials 9. By the above method, the existing framework structure 1 can be refurbished to the reinforced framework structure 1.

When a wooden building equipped with the refurbished framework structure 1 receives a strong external force (horizontal force) due to an earthquake, a typhoon, or the like, the framework structure 1 tends to deform in the shearing direction. Here, since the moment resistance joint is applied to the joint portion between the adjacent column member 2 and the plurality of reinforcing frame members 7, the deformation performance of the main body frame 1a in the framework structure 1 is the deformation performance of the panel member 11 itself. Higher than deformation performance. Therefore, if the framework structure 1 receives an external force of a certain value or more, the panel material 11 may be damaged.
In the case of a conventionally known bearing wall, if the panel material that imparts rigidity to the bearing wall is broken, the function as the bearing wall is impaired. On the other hand, according to the present embodiment, since the moment resistance joint is applied to the joint portion between the adjacent column material 2 and the reinforcing frame material 7, even after the panel material 11 is broken. The main body frame 1a secures and maintains a high toughness state and can resist external force. As a result, sufficient earthquake resistance can be maintained even in various wooden buildings including traditional wooden buildings.

Further, since a plurality of reinforcing frame materials 7 are provided and the plurality of reinforcing frame materials 7 are arranged at intervals in the vertical direction, the plurality of reinforcing frame materials 7 are provided in the adjacent existing pillar materials 2. It will be in a state of being connected at multiple points. Therefore, it is possible to improve the deformation performance of the main body frame 1a composed of the existing pillar members 2 adjacent to each other and the plurality of reinforcing frame members 7.

Further, the column material 2 and the reinforcing frame material 7 are joined by a plurality of joining rods 8 embedded in the joint portion between the column material 2 and the reinforcing frame material 7, and the plurality of joining rods 8 are joined. Since they are provided side by side at least in the vertical direction, the reinforcing frame material 7 can be reliably moment-resisted to the column material 2, and the main body frame composed of the existing column material 2 and the reinforcing frame material 7 adjacent to each other can be reliably joined. The deformation performance of 1a can be significantly improved.

Further, the joining rods 2a on the pillar material 2 side and the joining insertion holes 7a on the reinforcing frame material 7 side are set so that the hole diameter is larger than the diameter of the joining rod material 8. A gap is formed between the material 8 and the material 8, and the gap is filled with an adhesive. Therefore, when the adhesive is cured while holding the bonding rod, the stress is applied to the adhesive force of the adhesive and the bonding rod. It is transmitted through the material 8 to generate a bonding strength. Therefore, the reinforcing frame material 7 can be reliably moment-resisted to the column material 2, and the deformation performance of the main body frame 1a composed of the existing column material 2 and the reinforcing frame material 7 adjacent to each other can be significantly improved. Can be done.

Further, the reinforcing frame material 7 is divided into one pillar material 2 side and the other pillar material 2 side in the adjacent existing pillar material 2, the first divided body 70 on the one pillar material 2 side, and the other pillar. The first divided body 70 and the second divided body 71 have the second divided body 71 on the material 2 side, and since the adjacent ends 70a and 71a are joined to each other, the first divided body 70 Is temporarily attached to a plurality of joining rods 8 provided on one pillar 2 side, and then the second divided body 71 is temporarily attached to a plurality of joining rods 8 provided on the other pillar 2. The first divided body 70 and the second divided body 71 can be integrated on the attached body. Therefore, the reinforcing frame material 7 can be easily incorporated into the existing framework structure 1, and the framework structure 1 can be easily reformed.

Further, since the panel material 11 is located between the existing pillar materials 2 adjacent to each other and is fixed to the reinforcing frame material 7, the reinforcing frame material 7 can be reliably attached as a base material. Further, since the panel material 11 is located between the existing pillar materials 2 adjacent to each other, the existing framework structure 1 can be made to look like a true wall.

Further, since the reinforcing material 9 provided in contact with the upper surface and / or the lower surface of the reinforcing frame material 7 is further provided, the shearing force of the joint portion between the adjacent pillar material 2 and the reinforcing frame material 7 can be borne. It is possible to suppress the movement of the reinforcing frame material 7 to move upward and the movement of the reinforcing frame material 7 to move downward. Therefore, the deformation performance of the main body frame 1a composed of the adjacent existing pillar material 2 and the reinforcing frame material 7 can be remarkably improved.

Further, since the shear reinforcing structure portion 10 provided at least from the upper horizontal member 4 to the beam 6 and connecting at least the upper horizontal member 4 to the beam 6 is further provided, the framework structure 1 exerts a strong external force (horizontal force). In response, the framework structure 1 can be reinforced against the horizontal shearing force applied to the framework structure 1. Therefore, the deformation performance of the main body frame 1a composed of the adjacent existing pillar material 2 and the reinforcing frame material 7 can be remarkably improved.

Further, in the step prior to filling the voids with the adhesive, the first divided body 70 is temporarily attached to the plurality of joining rods 8 inserted into the plurality of joining insertion holes 2a in the one pillar material 2. After attaching and shifting the first divided body 70 by tilting it forward or backward with respect to the joining rod 8 as an axis, the second divided body 71 is moved into a plurality of joining insertion holes 2a in the other pillar material 2. The first divided body 70 and the second divided body 71 are temporarily attached to a plurality of joining rods 8 inserted into the pillars, and the adjacent ends 70a and 71a are joined to be integrated with each other. Moment resistance bonding between the column material 2 and the reinforcing frame material 7 using a plurality of bonding rods 8 is possible without forming a through hole in the material 2. Therefore, the reinforcing frame material 7 can be easily incorporated into the existing framework structure 1, and the framework structure 1 can be easily reformed.

[Modification example]
The embodiment to which the present invention is applicable is not limited to the above-described embodiment, and can be appropriately changed without departing from the spirit of the present invention. Hereinafter, a modified example will be described. The following modifications may be combined as much as possible. Further, in each of the following modifications, the elements common to the above-described embodiment are designated by a common reference numeral, and the description thereof will be omitted or simplified.

[Modification 1]
The reinforcing frame material 7 in this modification is divided into one pillar material 2 side and the other pillar material 2 side in the adjacent existing pillar material 2, the first divided body 70 on one pillar material 2 side, and the other. The second divided body 71 on the side of the pillar member 2 is provided, and as shown in FIG. 6, the vibration damping member 72 is provided between the adjacent ends 70a and 71a. The adjacent ends 70a and 71a are joined to each other via the vibration damping member 72.

In order to secure a space for providing the vibration damping member 72 between the adjacent ends 70a and 71a, the notch depth in the front-back direction is the thickness dimension of the vibration-damping member 72 (front-back direction). Dimension) minutes are taken into consideration.
That is, the thickness dimension (dimension in the vertical direction) of the reinforcing frame material 7 is 90 mm as described in the above embodiment, and within this dimension range, the first division body 70 and the second division The central end portions 70a and 71a of the body 71 are cut out, and the vibration damping member 72 is provided.

As the vibration damping member 72 in this modification, a viscoelastic body that attenuates vibration is adopted. The viscoelastic body is formed of, for example, a high damping rubber in which silica is added to a base rubber having a CC bond in the main chain and a silane compound is blended with the silica.

The vibration damping member 72 is fixed to the central end portion 70a of the first partition body 70 with an adhesive or the like. Further, the second divided body 71 is also fixed to the central end portion 71a with an adhesive or the like.
Although not shown, a material (for example, a metal such as iron or aluminum) that easily adheres the vibration damping member 72, which is a high damping rubber, is integrated into the notch in the first divided body 70 and the second divided body 71. The vibration damping member 72 may be fixed to the material after the vibration damping member 72 is provided.

According to this modification, a vibration damping member 72 is provided between the adjacent ends 70a and 71a, and the adjacent ends 70a and 71a are joined to each other via the vibration damping member 72. Therefore, sufficient seismic resistance can be maintained even in various wooden buildings including traditional wooden buildings.
That is, when the framework structure 1 receives an external force, the adjacent existing column members 2 try to move so as to tilt in the same direction, and the reinforcing frame member 7 tries to rotate upward or downward accordingly. However, since the vibration damping member 72 is provided between the adjacent ends 70a and 71a of the first divided body 70 and the second divided body 71 in the reinforcing frame material 7, the vibration damping member 72 is provided. According to 72, the vibration generated during the operation of the reinforcing frame material 7 can be suppressed. Along with this, the operation of the adjacent existing column members 2 connected by the reinforcing frame member 7 can also be suppressed, so that the seismic resistance of the frame structure 1 and the wooden building provided with the frame structure 1 is improved. be able to.

It should be noted that, for example, for reasons such as wanting to reduce the number of joining insertion holes 2a (joining insertion holes) formed in the existing pillar material 2, the existing pillar material 2 and the reinforcing frame material 7 adjacent to each other are joined together. Moment resistance joints that resist external forces may not be applicable to the parts. In such a case, as in the present modification, the vibration damping member 72 may be provided between the adjacent ends 70a and 71a to reinforce the framework structure 1.

[Modification 2]
The reinforcing frame material 7 in the above embodiment has a first divided body 70 and a second divided body 71 that can be matched in the manner of phase-joining, but the reinforcing frame material 7A in this modification Has a first divided body 70A, a second divided body 71A, and a third divided body 73A, as shown in FIG. 7.

The central side end portion 70Aa of the first divided body 70A and the central side end portion 71Aa of the second divided body 71A are notched symmetrically in an L shape in the left-right direction in a plan view, and the end faces are abutted against each other. It is placed in a state of being.
The third divided body 73A is a plate-shaped body that is fitted over the notch portion at the central side end portion 70Aa of the first divided body 70A and the notch portion at the central side end portion 71Aa of the second divided body 71A. ..
That is, the reinforcing frame material 7A is fitted with the third divided body 73A over the notch portion at the central side end portion 70Aa of the first divided body 70A and the notch portion at the central side end portion 71Aa of the second divided body 71A. It is composed by being combined.

The joining between the first divided body 70A and the third divided body 73A and the joining between the second divided body 71 and the third divided body 73A are, for example, joining with an adhesive, the first divided body 70A and the third divided body 73A, and the like. Joining with a fixing tool such as a bolt and a nut penetrating the second dividing body 71 and the third dividing body 73A, or joining with a combined use of an adhesive and a fixing tool, or the like is appropriately selected. When joining with bolts and nuts, the surface is counterbored within the range where the strength of the first divided body 70A, the second divided body 71A, and the third divided body 73A does not decrease extremely, and the concave portion formed in the portion thereof. The head of the bolt and the nut may be stored in the bolt.

When the reinforcing frame material 7 is provided between the existing pillar materials 2 adjacent to each other, the first divided body 70A is tilted toward the back side and displaced from the center, and then the second divided body 71A is placed on the right side pillar material. Temporarily attach to a plurality of joining rods 8 inserted into the plurality of joining insertion holes 2a in 2. That is, the second divided body is in a state in which the plurality of joining rods 8 protruding from the pillar material 2 on the right side are inserted into the plurality of joining insertion holes 7a formed in the second divided body 71. Temporarily attach 71A.
Then, the third divided body 73A is fitted over the notch portion at the central side end portion 70Aa of the first divided body 70A and the notch portion at the central side end portion 71Aa of the second divided body 71A.

After the third divided body 73A is fitted to both notches, the first divided body 70A, the second divided body 71A, and the third divided body 73A are joined (in this embodiment, joining with an adhesive).
After the plurality of reinforcing frame materials 7 are temporarily attached between the adjacent pillar materials 2 by the method as described above, the joining insertion holes 2a on the pillar material 2 side and the joining insertion holes on the reinforcing frame material 7 side are inserted. Each of the holes 7a is filled with an adhesive and cured.

According to this modification, the reinforcing frame material 7A is a third portion extending over a notch portion at the central side end portion 70Aa of the first division body 70A and a notch portion at the central side end portion 71Aa of the second division body 71A. Since the split body 73A is fitted and configured, for example, the central side end portion of the first split body 70 and the central side end portion of the second split body 71 are matched with each other in the manner of a phase joint, and the reinforcing frame is reinforced. The lengths of the first divided body 70A and the second divided body 71A can be shortened as compared with the case of constituting the material 7A.
As a result, when the reinforcing frame material 7A is provided between the existing pillar members 2 adjacent to each other, the angle at which the first divided body 70A is tilted toward the back surface side can be reduced, so that when the framework structure 1 is reinforced. The work space can be reduced in the thickness direction (front-back direction) of the entire framework structure 1. Further, since it is not necessary to increase the hole diameters of the joining insertion hole 2a on the pillar 2 side and the joining insertion hole 7a on the reinforcing frame 7A side more than necessary, the strength of the pillar 2 as a structure is not required. The decrease can be suppressed as much as possible.

[Modification 3]
In the above embodiment, a plurality of joining insertion holes 2a on the pillar material 2 side are formed so as not to penetrate the pillar material 2 in the left-right direction, but in this modification, although not shown, they are not shown. The pillar material 2 is formed with a plurality of insertion holes for joining that penetrate the pillar material 2 in the left-right direction. A plurality of joining rods 8 can be inserted from the outside into the plurality of joining insertion holes. Therefore, it is not necessary to divide the reinforcing frame material 7 into the first divided body 70 and the second divided body 71. That is, when the vibration damping member 72 in the above modification is not used, the reinforcing frame material 7 may not be divided.

[Modification 4]

It is possible to bear the shearing force of the portion, and it is possible to suppress the movement of the reinforcing frame material 7 to move upward and the movement of the reinforcing frame material 7 to move downward. Therefore, the deformation performance of the main body frame 1a composed of the adjacent existing pillar material 2 and the reinforcing frame material 7 can be remarkably improved.
Further, since the wooden panel 20 for construction itself is made of wood, it has a certain degree of tenacity, but when the framework structure 1 receives a strong external force, it may be destroyed. However, since moment resistance joining is applied to the joints of the plurality of reinforcing frame members 7 with respect to the adjacent column members 2, the building wood panel 20 is provided in contact with the upper surface and / or the lower surface of the reinforcing frame members 7. Therefore, the toughness of the framework structure 1 (main body frame 1a) composed of the adjacent column members 2 and the plurality of reinforcing frame members 7 can be improved.

In this modification, the building wood panel 20 is mentioned as another reinforcing material, but other reinforcing materials may be adopted. For example, a brace or a brace may be adopted as a reinforcing material, or a truss-shaped frame may be adopted as a reinforcing material.

[Modification 5]

A reference example will be described below. In each of the following modifications, the elements common to the above embodiments are designated by a common reference numeral, and the description thereof will be omitted or simplified. The modifications listed below may be combined with the above-described embodiments and each modification as much as possible.

[Reference Example 1]
When performing seismic retrofitting of the framework structure in traditional wooden buildings such as temples and shrines, large-scale demolition work and restoration work were indispensable. Therefore, the cases of renovation that have been carried out so far tend to be expensive, and there is a problem that it is difficult to renovate in a general temple.
Therefore, in recent years, it has been required to apply the structure of the bearing wall as described in Patent Document 1 to the frame structure of various wooden buildings including the traditional wooden building as described above. However, even if the structure of the bearing wall is applied to the frame structure of a wooden building, for example, if the applied structure is complicated or partial demolition work is required, the labor and cost involved in the construction will increase. It is not preferable because it increases.

In view of such circumstances, the framework reinforcing structure in this reference example is configured to include at least existing column members 2 adjacent to each other at intervals as shown in FIGS. 14 (a) to 14 (c).

After that, the central side end portion 70a of the first divided body 70 and the central side end portion 71a of the second divided body 71 are joined by the above method, and further, the panel material 11 is attached.

Further, in the example shown in FIG. 14 (c), the joining metal fitting 27 is used for joining the first divided body 70 and the second divided body 71 and the existing pillar member 2.
The joining metal fitting 27 is formed in a U-shape (may be T-shaped or L-shaped) in a plan view, and is fixed to the existing pillar member 2 by a screw 27a. On the other hand, an insertion hole 28 having a shape into which the joining metal fitting 27 can be inserted is formed at the end of the pillar member 2 side of the first divided body 70 and the second divided body 71.
The first divided body 70 and the second divided body 71 and the joining metal fitting 27 are formed with through holes for passing the dowel material 27b, and are joined to the first divided body 70 and the second divided body 71. The metal fitting 27 is joined by a dowel material 27b.

Then, the attachment of the first divided body 70 and the second divided body 71 is performed in the manner of a phase-breaking joint as shown in FIG. That is, one of the first divided body 70 and the second divided body 71 (referred to as the first divided body 70 in this reference example) is first different from the joint fitting 27 fixed to the pillar member 2. Align the insertion holes 28 and temporarily attach them. Subsequently, by tilting the first divided body 70 in the direction opposite to the cutout side, a space for temporary attachment of the divided body (second divided body 71 in this reference example) to be temporarily attached later is provided. Secure. Subsequently, the insertion hole 28 of the second split body 71 is temporarily attached so as to match the joining metal fitting 27 fixed to the pillar member 2. After that, the central side end portion 70a of the first divided body 70 and the central side end portion 71a of the second divided body 71 are joined by the above method, and further, the panel material 11 is attached.

Note that FIG. 14 (d) is a modified example of the example shown in FIG. 14 (c), and the reinforcing frame material 7B is not divided. When such a reinforcing frame material 7B is used and the joining metal fitting 27 is used, insertion grooves 29 penetrating in the vertical direction are formed at both ends of the reinforcing frame material 7B in the length direction. In this way, the reinforcing frame material 7B can be fitted to the joint fitting 27 by sliding from above or below. The first divided body 70 and the second divided body 71 and the joining metal fitting 27 are joined by a dowel material 27b.

According to this reference example, since the joining rod 8 in the above embodiment is not used, the reinforcing frame materials 7 and 7B can be easily incorporated into the existing framework structure 1, and the framework structure 1 can be easily reformed. .. Therefore, when the framework reinforcing structure in this reference example is applied to the framework structure of various wooden buildings, it is possible to reduce the labor and cost related to the construction.

[Reference Example 2]
