The reaction force transmission fitting 7 has a rectangular plate-like shape and has a size corresponding to the vertical width of the beam 5. The reaction force transmission fitting 7 is combined with the main fixture 1 in a crossing manner, that is, in a shearing direction which is downward in FIG. Is done. Then, the reaction force transmission fitting 7 is placed on the outer surface 8 of the outer wall finishing material 6, and as a result, is positioned corresponding to the mounting surface 9 of the girder 5, and presses the four stainless-coil bolts 10 into the outer wall finishing material 6 and the girder 5. Accordingly, the reaction force transmission fitting 7 is fixed there.
[0021]
Before fixing the reaction force transmission fitting 7 as described above, three coach bolts 11 as a secondary fixing tool are press-fitted into the outer wall finishing material 6 and the girder 5, and the head 12 thereof is connected to the outer surface 8 of the outer wall finishing material 6.

Therefore, when the reaction force transmission fitting 7 is fixed, the reaction force transmission fitting 7 is supported by the coach bolt 11 by the inner surface 13 of the reaction force transmission fitting 7 coming into contact with the heads 12 of the three coach bolts 11.
[0022]
In such a bolt-shaped fixture reinforcing structure, if an unexpected load is instantaneously applied in the shearing direction, that is, the downward direction in FIG. 2, the head 4 of the main fixture 1 transmits the reaction force. The load is transmitted to the three coach bolts 11 which are the secondary fixtures via the metal fittings 7. On the contrary, since the three force bolts 11 support the load, the reaction force transmission metal fitting 7 transmits the reaction force to the main fixture. Therefore, the main fixing tool 1 is restricted from floating from the girder 5 or its head 4 being deformed.
[0023]
3 and 4 show a second embodiment. The reaction force transmission fitting 14 has a rectangular shape which is long at the top and bottom, and has a size that extends not only to the attachment surface 9 of the girder 5 but also to a part of the attachment surface 16 of the column 15, and has eight stainless coach bolts 17 attached to the outer wall.

Reference numeral 19 supports a reaction force transmission fitting 18.
[0025]
For this reason, the exterior finishing material 25 includes an opening 26 for receiving the reaction force transmission fitting 18, and the opening 26 is covered with a covering plate 27. The covering plate 27 is fixed to the exterior finishing material 25 with a stainless steel coach bolt 28. The reaction force transmission fitting 18 and the main fixture 1 are engaged with each other by forming a screw portion 30 in the body portion 29 of the main fixture 1 and forming a screw portion corresponding to the reaction force transmission fitting 18 and screwing together. It is done by doing.
[0026]
Therefore, when an unexpected shear load is applied to the head 4 of the main fixture 1 downward in FIG. 5, the upper secondary fixture 19 moves to the left in FIG. Although it is going to move rightward, conversely, the reaction force is transmitted from the lower secondary fixture 19 to the upper secondary fixture 19 via the reaction force transmission bracket 18, so that the main fixture 1 It is prevented that the mounting target member 20 is lifted or its head 4 is deformed.
The other structure and the operation and function of each part are the same as those in the first embodiment, and common parts are denoted by the same reference numerals, and redundant description is omitted.
