Insert the bolt 66 into the bolt hole 73 of the pillar 68 via the, and tighten the nut 66a on the back of the pillar 68, and insert the insertion piece 63 of the metal fitting 61 into the joint end of the other member such as the beam 69. A notch groove 70 is provided for inserting the insertion piece 63 into the groove 70, and the beam 69
From the side surface of the insert hole 63, a hole 71 is opened so that the drift pin 67 can fit in the pin hole 64 provided in the insertion piece 63, and the drift pin 67
Both members are joined by press-fitting. The bolt hole 65 'provided in the fixing portion 62 of the joining metal fitting 61 is a pillar.
It is for fixing a joint fitting that is similarly attached to the back surface of 68, and is fixed in the same manner as above by bolts 66 'and nuts 66'a inserted into bolt holes 73' formed in the pillar 68. Further, the narrow groove 72 provided on the beam 69 is
The width and depth are such that the bolt head and nut after fastening can be accommodated.

[0004]

Since the above-mentioned joining metal fitting requires strength, it is made of a steel plate or the like, and fixing bolt holes or the like are also supplied in a pre-opened form. When using it, it is possible to pre-install bolt insertion holes and grooves in the wood according to the bolt holes and insertion pieces of these metal fittings, but since wood sometimes contracts and expands, it is processed on site. Is desirable. Therefore, at the construction site, it is necessary to provide bolt holes and grooves for insert pieces at the joints of pillars and beams according to the specifications of these joint fittings, but it is not necessary to machine bolt holes and grooves one by one. If it takes too much time, or if an error occurs in the mutual intervals of the processing positions, there is a problem that the metal fittings cannot be used or the pillars after processing cannot be used. The present invention is for solving the above-mentioned problems, and proposes a joining portion processing machine for a column beam or the like, which is easy to move and can perform required processing without error.
