After inserting the locking plates 68, 68 of the wood connecting fitting 51 into the circular holes 73, 73 of 2, 2, 72, the whole wood connecting fitting 51 is pulled down to the locking plates 68, 6 respectively.
8 is located in each of the cavities 75, 75 of the locking holes 72, 72. In this state, the locking plates 68, 68 are locked to the left and right sides of the slits 74, 74 and cannot be pulled out, and the plate 61 is maintained in the vertical posture on the side surface 71 of the column 52. Next, the opening portion 81 of the beam 53 is lowered from above the plate 61 so that the cut groove 82 thereof fits into the plate 61, and the engaging pin 54 is moved to the plate 61.
It is fitted in the engaging groove 63 of. At this time, the beam 53 is shown in FIG.
In the state of reference numeral 53 ', the engaging pin 54 abuts on the upper position of the inclined surface 64 of the engaging groove 63 as shown by reference numeral 54', and the beam 53 is subsequently moved downward. The dowel pin 54 moves downward while being guided by the inclined surface 64 of the engaging groove 63, and moves the entire beam 53 to the side surface 71 side of the column 52. The engaging pin 54 is engaged with the engaging groove 63.
When reaching the lower end of the beam 53, the wooden mouth of the beam 53 is joined to the side surface 72 of the pillar, and the pin hole 85 of the wooden mouth portion 81 and the pin hole 65 of the plate 61 are aligned with each other.
By inserting the connecting pin 55 into the column, the pillar 52 and the beam 53 can be connected via the wood connecting fitting 51 as shown in FIG. 7. In addition, this timber connection structure can also be applied to the connection of two beams intersecting in a horizontal plane.

との連結強度が高強度となるという効果がある。Further, in the wood connecting structure of the invention of claim 2, since the wood connecting metal having the locking projection formed of the linear rod body is used as described above, the wood connecting metal is attached to the side surface of the reference side wood. The locking hole formed may simply be a straight drill hole.
Therefore, since the locking hole can be processed by a normal drill for drilling, a dedicated processing device called a milling cutter as in the known example of FIGS. 6 to 7 is not required, and the facility cost is low. The effect is that the processing is extremely simple. Even with such a simple fitting structure (fitting structure of a drill hole and a locking projection made of a rod), the locking projection is directed downward and obliquely forward with respect to the locking hole. Since the fitting is fitted, the wood connecting fitting can be securely and strongly retained on the side surface of the reference side wood when the locking projection is fitted in the locking hole. There is an effect that the connection strength with the wood becomes high.
