2. Description of the Related Art Conventionally, various reinforcing hardware (joining hardware) or reinforcing members have been used to reinforce a joint (joint) between two members of a wooden building which are joined so as to cross each other. ing. For example, as shown in FIG. 10 , a T-shaped corner metal piece 202 is applied and nailed between the pole 14 and the base 16 which are hooked and connected, and reinforced as shown in FIG. 11. The base 204 is provided diagonally between the bases 16A and 16B.

It is simply made of a plate-shaped metal member or member, and is merely reinforced by the planar strength of the plate surface of the metal member or member, so that the joint between the two members (for example, the pillar 14 and the base 16) is sufficiently formed. There was a drawback that it could not be reinforced with great strength.

Further, as shown in FIG. 12 , for example, in a three-story building, a pillar 14

FIG.
Reference numeral 214 denotes an anchor bolt for fixing the base 16 to the foundation 28.

[0005] The joining hardware includes two engaging plate portions 206,
Two members joined to each other in the building can be three-dimensionally reinforced by a pair of triangular side plates 210 provided along the side edge of the 208. However, when a considerable amount of vibration is applied to the building not only from up, down, left and right but also from all directions, such as an earthquake, and a load is applied to the side plate portion 210 so that a side pressure is applied to the plate surface of the side plate portion 210,
The metal joint has a drawback that it is difficult to withstand the vibration and the joint between the two members is broken.

Further, these reinforcing hardware or members are
It is joined by straddling two members that are joined to each other in the building, and is fixed by driving in a bolt or a nail. At this time, the reinforcing metal is used so as not to hinder the driving of the bolt or the nail. Since it must have a structure, there is a disadvantage that its reinforcing structure is restricted.

For example, as shown in FIG. 5A, an iron plate is punched to form a continuous strip 100 having a width W corresponding to the engagement plate portions 32 and 34, and as shown in FIG. Is punched to form a trapezoidal plate 102 in which a portion corresponding to the triangular side plate portion 36 and a portion corresponding to the inclined plate portion 38 having the width dimension W / 2 are integrally continuous. Next, the continuous band-shaped plate 100 is bent at a right angle by the line L1, and the trapezoidal plate 102

5 and FIG. 6 show a method of connecting a seismic retrofitting hardware 1.
When forming 0, it is preferable that the side edge 100a and the inclined edge 102a and the edge 100b and the parallel edge 102b are welded to each other.
One of the 2b (one of the two places) is welded, and the other has a load transmitting action so that the load applied to the edge 100b or the parallel edge 102b is transmitted to the other parallel edge 102b or the edge 100b. If it is possible, it is not always necessary to weld, but only to abut each other.

Further, the connection seismic retrofitting hardware 10 of the present invention comprises:
In addition to the methods shown in FIGS. 5 and 6, for example, a single iron plate may be drawn in a mold to form a monolithic metal having a shape as shown in FIG.

[0021] The connection seismic retrofitting hardware 10 of the present invention is a pillar 14 '.
It is shown in detail in FIGS. As can be seen from these figures, the engagement plate portions 32, 34 of the connection seismic retrofitting metal fitting 10 are engaged with the L-shaped member surfaces 14'a, 18a of the column 14 'and the spar 18, respectively. The bolts 40, 40 'driven through these engaging plate portions 32, 34 fix the bolts 14', spar 18 respectively to the columns 14 ', 18 and
As shown in the figure, the triangular side plate portion 36 is engaged with the streak 24, and is fixed to the streak 24 by a bolt 42 and a nail 44 driven through the side plate portion 36.

As can be seen from FIG. 3, the inclined plate portion 38 is narrower than the engaging plate portions 32 and 34, so that the bolt driving machine does not interfere with the inclined plate portion , 34 can be operated. Since the bolt and nail driving surface of the triangular side plate 36 is open, the bolt and nail driving operation can be easily performed.

As can be seen from FIGS. 1 and 2, in the illustrated embodiment, a T-shaped joint 2 between the pillar 14 'and the beam 18 is provided.
2, the bolts 40 'for fixing the engagement plate portions 32 to the columns 14' are provided on both sides of the joints 10 through the joints 10 and the columns 14 '. Is shown in the form of a through bolt.

In the same manner, the connection seismic reinforcement metal fitting 10 attached to the L-shaped joint 20 between the column 14 and the base 16 in FIG.
And the bolt 24 and the nail 44
Has been fixed by.

As described above, the connection seismic retrofitting hardware 10 is engaged with the intersecting member surfaces of two members such as columns, bases, and girders of the wooden building 10 which are joined in an L-shape or a T-shape. Two engaging plate portions 32, 34, a triangular side plate portion 36 provided on one side edge of the engaging plate portions 32, 34, and two engaging plates along the slope of the side plate portion 36. It comprises a plate portion disposed on three three-dimensionally different planes with an inclined plate portion 38 provided so as to extend between the opposite edges of the portions 32 and 34. Therefore, even if a considerable vibration load such as an earthquake occurs in any direction, the three plate portions 32 or 34, 36, 3
8 can withstand this vibration load while complementing each other.

More specifically, the connection seismic retrofitting hardware 1
0 is attached so that the triangular side plate portions 36 are perpendicular as shown in FIGS.
When a vertical vibration is applied to the wooden structure 10, the side plate portion 36 arranged along the thickness in the vibration direction acts to withstand the vibration, and when a horizontal vibration is applied to the wooden building 10, The engaging plate portions 32, 34, the side plate portions 36, or the inclined plate portions 38 arranged along the plate thickness in the vibration direction act so as to withstand this vibration. Accordingly, members such as columns and bases, columns and girders of the wooden building 12 to which the connection seismic retrofitting hardware 10 is attached are reinforced and joined with high strength, and the entire wooden building 12 has high seismic resistance. Will have. Each of the plate portions 32, 34, 36, and 38 is set so that the load received by one plate portion is transmitted to another plate portion adjacent thereto, so that the load is transmitted in any direction. The vibration load is also quickly transmitted to the plate portion at the seismic position where the plate thickness is oriented in the vibration direction, so that a high seismic action can be obtained as a whole.

The vibration applied to the wooden building 12 in the actual earthquake is a form in which these vertical and horizontal vibrations are mixed and mixed.
Since the plurality of plate portions are three-dimensionally combined so as to have different plane arrangements, the thickness of any one of the plate portions acts to withstand vibration, and can withstand earthquakes having complicated vibration forms. .

In the above-described embodiment, for example, the connection seismic reinforcement metal fitting 10 attached between the column 14 and the base 16 is fixed to the base 16 with bolts 40. For example, as shown in FIG. The anchor 16 may be fixed together with the base 16 to the anchor bolt 50 planted on the base 28. In this case, the alignment with the anchor bolt 50 can be easily performed.
The connection seismic retrofitting metal fitting 10 is provided with the engagement plate portion 34 (and / or 3
It is preferable to provide the anchor bolt through slot 34a in 2).

It has a folded piece 38A which is in contact with the fold. Since the bent piece 38A has a plane arrangement parallel to the side plate portion 36, the reinforcing metal piece 10A acts so as to withstand the load received from the plate thickness direction of the bent piece 38A in the same manner as the side plate portion 36, as shown in FIG. It has a higher earthquake resistance than the reinforcing hardware 10. The upper and lower edges of the bent piece 38A are
