〔Example〕

Hereinafter, an embodiment of a metal joint for construction according to the present invention will be described with reference to the drawings.

FIG. 1 shows an exploded perspective view of the first embodiment. In FIG. 1, 10 is a main member, and a wooden member 10 such as a pillar described later.
A back portion 11 fixed to 0 and a pair of side portions 13 projecting in the same direction at right angles to the back portion 11 are formed on both sides of the back portion 11. A plurality of bolt holes 12 are provided in the longitudinal direction of the back portion 11.

Reference numeral 14 denotes a fitting portion, which is provided at a position opposite to the back portion 11 of the pair of side portions 13 so as to project above the upper edge of the side portion. The tip of the fitting portion 14 is formed narrow.

A receiving plate 15 is fixed to the bottom of the main member 10.
This receiving plate 15 slightly protrudes from the back 11,
The width is wider than the side interval of the auxiliary member 20 described later.

16 is a locking piece, which is provided at the lower end of the pair of side portions 13 of the main member 10,
Each is formed so as to project to the outside.

Reference numeral 20 denotes an auxiliary member, which includes a back portion 21 fixed to a joint of a wooden member 200 such as a beam, which will be described later, and a pair of side portions 23 projecting in the same direction at right angles to the back portion 21 on both sides of the back portion 21. Has been formed. The distance between the pair of side portions 23 of the auxiliary member 20 is wider than the distance between the side portions 13 of the main member 10, and is formed so as to wrap the entire main member 10 inside.
Further, a plurality of bolt holes 22 are provided in the vertical direction of the back portion 21.

Reference numeral 24 is a fitting portion for fitting the fitting portion 14 therein, and is formed at a position above the back portion side of the side portion 23 of the auxiliary member 20. In the present embodiment, a notch is formed in the upper part of the pair of side portions 23 in the horizontal direction, and the upper pieces of the notch are respectively bent inward.

Reference numeral 25 is a notch for locking the locking piece 16, which is formed at the lower end on the back side of the side part 23 of the auxiliary member 20.

Reference numeral 30 denotes a plug, which is embedded in the wooden member 200 and fixedly used with an adhesive or the like. Usually, the wooden member is inferior in hardness to metal or the like, so that there is a defect that the screw thread provided on the wooden member is crushed when the bolt is strongly tightened. Therefore, even when joining the wooden members, there are problems that the joining metal fittings and the joint shape are complicated and the construction method is complicated. By using this plug 30, such a problem can be solved. By forming the concave portion 31 on the outer peripheral surface of the plug 30, the plug 30 and the wooden member 200 can be more firmly fixed to each other. 32 is a bolt that is screwed into the plug 30. Reference numeral 40 is a wedge-shaped fixing member.

The joining metal fitting of the second embodiment shown on the right side of FIG. 2 is used for joining a wooden member 200 such as a relatively light girder, and lowers the heights of the main member 10 and the auxiliary member 20, and at the main member side. Part 13
The engaging piece at the lower end and the corresponding notch at the lower end of the auxiliary member side portion 23 are omitted.

Next, with reference to FIG. 2, a usage mode of the joining fitting of the present embodiment will be described.

For example, when the beam 200 is joined to the pillar 100, it is performed as follows. First, the bolt inserted in the bolt hole 101 of the pillar 100.
One of the bolt holes 12 of the back 11 of the main member is selected and inserted into 102, and tightened with a nut 103 to fix the main member 10 to the pillar 100. Note that this work is usually performed in a factory or the like.

At this time, the edge of the receiving plate 15 protruding from the back 11 is
When the pillar 100 is made to bite, the main member 10 is fixed to the pillar 100 more firmly.

On the other hand, the end portion of the beam 200 is formed with a joint for accommodating the auxiliary member 20. The plug 30 is embedded in the hole 201 provided in this connection and fixed by an adhesive. Next, the bolt 32 is inserted into the bolt hole 22 of the back 21 of the auxiliary member, and
The auxiliary member 20 is fixed to the joint of the beam 200 by being screwed into the plug 30. This work is also usually done at the factory.

After that, at the construction site, the auxiliary member 20 attached to the beam 200 and the main member 10 attached to the pillar 100 are joined. At this time, the auxiliary member 20 encloses the main member 10 and is joined so that the fitting portion 14 of the main member 10 and the fitting portion 24 of the auxiliary member 20 fit together. This way,
While the fitting portion 14 is fitted into the fitting portion 24, the auxiliary member
The side portions 23 of 20 are supported by the projecting portions on both sides of the receiving plate 30, and the locking pieces 16 of the main member 10 and the cutout portions 25 of the auxiliary member 20.
Locks. In this state, the joining of both members 10 and 20 has been firmly performed, but if there is a gap between the fitting portion 14 and the fitting portion 24, the fixing member 40 is driven between them to make it more The joining of both members 10, 20 is made firmer.

In addition, when the wooden member 200 such as a girder is light, the joining metal fitting of the second embodiment described above is used. However, the usage mode in this case is only that there is no locking piece and the locking portion of the cutout portion. Others are the same as above.

The present invention is not limited to the above embodiments, but includes various modifications within the scope of the gist. For example, the receiving plate 15 of the main member 10 has a function of supporting the auxiliary member 20 and concealing bolts and metal fittings, but the wooden member 200 is lightweight, and at a place where aesthetics need not be considered. In the case where the present joining fitting is used, the receiving plate 15 can be omitted.

[Effect of device]

As described above, according to the present invention, all the processing required for joining the wooden members is performed in a good working condition such as a factory.
At the construction site, it is possible to assemble a building with only a very simple joining work.
