In particular, in the beam receiving metal piece 1 of the first embodiment, the wood inserting portion 11a1 and the wood protruding portion 11a2 constituting the beam receiving metal fitting main body 11 have a height substantially the same as or slightly smaller than the diameter of the wood through hole 5a provided in the beam 5. It is integrally composed of a long plate 11a having a length equal to or longer than the length of the wood through hole 5a, and the wood of the beam 5 is spaced apart from the wood insertion portion 11a1 in the longitudinal direction thereof. Since the beam receiving metal body 11 is configured by providing two disc portions 11b having the same outer diameter as the inner diameter of the through hole 5a, the beam receiving metal fitting 1 can be efficiently manufactured with a small amount of material.

That is, the beam receiver 1 of the first embodiment is as shown in the long plate 11a having the shape shown in FIG. 3A, the disk portion 11b as shown in FIG. 3B, and FIG. 3C. By combining the beam receiving metal body 11 composed of the retaining prevention portion 11c and the plate-shaped member such as the fixing member 12 as shown in FIG. 4, it can be manufactured without the need for a special mold or the like. By freely designing the length of the long plate 11a, the number and spacing of the discs 11b, etc., it is possible to deal with not only the height of the wood but also the width, the required proof stress, the standard size, and the like. For example, by narrowing the interval in which the disc portions 11b are provided and increasing the number of disc portions 11b provided, the proof stress of the beam receiving metal fitting 1 of the first embodiment is inevitably improved, and the discs are located in places where stress is required. By attaching the portion 11b, it can be rationally reinforced, and it becomes easier to balance in the wood through hole 5a, and the beam receiving metal body 11 does not easily tilt to one side, so that the workability is improved and rattling occurs. The prevention effect is also improved.

Further, in the beam receiving metal fitting 1 of the first embodiment, since the fixing member 12 also serves as a wedge with respect to the beam receiving metal fitting main body 11, the effect of attracting the metal fitting and the wood to each other can be exhibited. The pulling effect is produced by a plurality or one beam receiving metal body 11. Further, when the fixing member 12 fixes two or more beam receiving metal bodies 11, the beam receiving metal body 11 can be prevented from rotating and rattling, and the beam 6 is usually dropped from above, so that the beam receiving metal body is normally constructed. It is difficult to construct if the 11 is rotated or if there is rattling, but the beam receiving metal body 11 is attached straight by the fixing member 12, so that the construction accuracy and workability are also improved. However, the role of the wedge of the fixing member 12 is an additional one, and if the mechanism is such that the beam receiving metal fitting 1 does not fall out from the inserted wood, the shape of the fixing member 12 and the fixing fitting hole 11a23, etc. I'm not particular about it.

In the first embodiment described above, two beam receiving metal bodies 11 are provided at arbitrary intervals in the vertical direction, but the present invention is not limited to this, and FIGS. 10 (a) and 10 (b) are described. ) And 3 or more columns 8 to be fixed at intervals as shown in FIGS. 11 (a) and 11 (b), and easy beam receiving metal fittings of different sizes according to the beam formation (beam height). Can be configured in. Especially,

For example, as shown in FIG. 10 (a), by providing four beam receiving metal bodies 11 at intervals in the vertical direction of the pillar 8, it corresponds to the beam 6 having a large beam formation (beam height). While the beam receiving metal can be constructed, as shown in FIG. 10B, by providing the three beam receiving metal bodies 11 at intervals in the vertical direction of the pillar 8, the beam formation (beam height) can be achieved. It is possible to construct a beam receiving metal fitting corresponding to a medium beam 6.

However, in the case shown in FIG. 10A, since it is necessary to fix four beam receiving metal bodies 11, two fixing members 12 having two fixing protrusions 12a1 described with reference to FIGS. 1 to 9 are provided. This may be used, but in the case shown in FIG. 10B, since it is necessary to fix three beam receiving metal bodies 11, for example, a fixing member 12'having three fixing protrusions 12a is used. Will be fixed. In the case shown in FIG. 10A, although not shown, one fixing member having four fixing protrusions 12a can also be used.

Further, as shown in FIGS. 11 (a) and 11 (b), by attaching 5 and 6 beam receiving metal bodies 11 to the columns 8 at intervals, the beam formation (beam height) can be increased, respectively. It can also handle a fairly large beam 6. However, in the case shown in FIG. 11A, since five beam receiving metal bodies 11 are used, for example, the fixing member 12 having the two fixing protrusions 12a shown in FIG. 4 and the like and FIG. 10 (b). ) Is fixed by using one fixing member 12'with the three fixing protrusions 12a, while the case shown in FIG. 11 (b) is shown in FIG. 10 (b). Two fixing members 12'with two fixing protrusions 12a can be fixed. Also in the cases shown in FIGS. 11A and 11B, although not shown, a fixing member provided with 5 or 6 fixing protrusions 12a can also be used. Even in the case shown in FIG. 11B, three fixing members 12 having two fixing protrusions 12a shown in FIG. 4 and the like may be used for fixing.

Therefore, according to the beam receiving metal fitting 1 of the first embodiment, the beam receiving metal fitting installation method, and the beam receiving structure, it is not necessary to prepare the beam receiving metal fittings of different sizes, so that the cost can be reduced and the storage location can be reduced. It is possible to reduce the number of items in stock, the labor of inventory management, and the like.

In the description of the beam receiving metal fitting 1 of the first embodiment, the beam receiving metal fitting is formed by using a plurality of beam receiving metal fitting bodies 11 of 2 to 6 and one or a plurality of fixing members 12, 12'. Although it has been described to be constructed, in the present invention, it is of course possible to construct the beam receiving metal fitting by using one beam receiving metal fitting main body 11 and one fixing member, and seven or more beams are used. May be. Further, as described above, the beam 5 and the beam 6 may be fixed by the beam receiving metal fitting 1, or the column 8 and the beam 6 may be fixed, and the timbers other than those described above may be fixed to each other. Is also good.

Embodiment 2.
As shown in FIGS. 1 to 11, the beam receiver 1 of the first embodiment is described as constructing a single-sided beam receiver 1, but the beam receiver 2 of the second embodiment is shown in FIG. 12 (a). , (B) and 13 (a) and 13 (b) show, a double-pull, that is, a beam receiving metal fitting capable of receiving the beam 6 on both sides will be described. The beam receiving metal fitting 2 of the second embodiment is composed of the beam receiving metal fitting main body 21 and the fixing member 12, but since the fixing member 12 has the same configuration as that of the first embodiment, only the beam receiving metal fitting main body 21 will be described. do. Further, the same components as those of the beam receiving metal fitting 1 of the first embodiment will be described with the same reference numerals.

12 (a) and 12 (b) are plan views and front views of the beam receiving metal fitting main body 21 constituting the beam receiving metal fitting 2 of the second embodiment according to the present invention, respectively.

As shown in FIGS. 12A and 12B, since the beam receiving metal fitting 2 of the second embodiment is a double-pulling beam receiving metal fitting, the long plate 21a of the beam receiving metal fitting main body 21 is the wood insertion portion 11a1. The wood protrusions 11a2 are provided on both sides in the longitudinal direction.

Here, the beam receiver 2 of the second embodiment is different from the beam receiver main body 11 of the beam receiver 1 of the first embodiment shown in FIGS. 1 (a) and 1 (b) and FIGS. 2 (a) and 2 (b). Unlike this, the retaining prevention portion 11c is not provided, and the beam receiving metal body 21 is fixed to the wood by sandwiching the wood with fixing members 12 from both sides of the wood such as the beam 5 and the pillar 8 to be fixed.

That is, when the beam receiving metal body 21 constituting the beam receiving metal fitting 2 of the second embodiment is passed through the wood through hole of the wood, the wood protruding portions 11a2 and 11a2 protrude from both sides of the wood, respectively, and the beam receiving metal fitting main body 21 as it is. In any direction, for example, as shown in FIGS. 13 (a) and 13 (b), the fitting hole portion 11a23 for fixing the boundary portion with the wood inserting portion 11a1 of each of the wood protruding portions 11a2 and 11a2. , 11a23 are fitted with two fixing protrusions 12a of the fixing member 12, and the beam receiving metal body 21 is fixed to the beam 5 so that the beam 5 which is the wood to be fixed is sandwiched between the two fixing members 12 from both sides. do.

As a result, when the beam receiving metal piece 2 of the second embodiment is used, it is possible to construct the double-pulled beam receiving metal fitting 1, and it is possible to receive different beams 6 on the left and right sides of the beam 5 to be fixed. It becomes.

Therefore, according to the beam receiving metal fitting 2 of the second embodiment, the wood protruding portions 11a2 and 11a2 are provided on both sides of the wood inserting portion 11a1 of the beam receiving metal fitting main body 21, respectively, and the wood projecting portions 11a2 and 11a2 are provided with the wood inserting portions 11a1 respectively. In the first embodiment, the two fixing protrusions 12a of the fixing member 12 are fitted into the fixing fitting holes 11a23 and 11a23 provided at the boundary portion of the above to construct the double-pulled beam receiving metal fitting 1.

Etc. can be obtained.

Further, according to the beam receiving metal fitting 2 of the second embodiment, three to six columns 8 are spaced apart in the vertical direction of the pillar 8 to be fixed as in the beam receiving metal fitting 1 of the first embodiment shown in FIGS. 10 and 11. By attaching the beam receiving metal body 31 of the book, it is possible to easily configure the beam receiving metal fittings for double pulling having different sizes according to the beam formation, so that it is not necessary to prepare the beam receiving metal fittings having different sizes. The cost can be reduced and the storage space can be reduced.

Further, of course, the beam receiving metal fitting 1 of the first embodiment and the beam receiving metal fitting 2 of the second embodiment may be used together for the same fixing target such as a beam or a column. For example, by attaching two beam receivers 2 of the second embodiment for double pulling to the same fixing target, and one beam receiving metal fitting 1 of embodiment 1 for one-sided pulling below the two beam receiving metal fittings 2 for double pulling. The side where only the wood protrusion 11a2 of the beam receiver 2 of the second embodiment protrudes, and the wood protrusion of the beam receiver 2 of the second embodiment for double pulling and the beam receiver 1 of the first embodiment for pulling one side. Beams having different beam formations (beam heights) on the 11a2 side can be attached to the same fixing target. This also applies to the beam receiver 3 for single pulling of the third embodiment and the beam receiving metal 4 for double pulling of the fourth embodiment, which will be described later, and the same applies to the beam receiving metal for the single pulling of the third embodiment. Of course, 3 and the beam receiving metal fitting 4 for double pulling of the fourth embodiment may be mixed and used.
