Field of the Invention The present invention relates to a joining structure and joining hardware of a wooden frame, and joins a horizontal member such as a girder or a beam mainly made of a lightweight steel frame such as lightweight grooved steel or lightweight H-shaped steel and a wooden column or beam. When applied.

  Even in wooden buildings, steel beams are used when a large opening or room is required, and in the case of wooden construction, lightweight girder steel or lightweight H-shaped mainly for horizontal members such as torso and beams. Steel frames such as steel are used.

  For example, FIGS. 10 to 14 show an example, and FIGS. 10 (a) and 10 (b) show a wooden frame using light-duty steel as a steel beam, and two steel beams made of light-duty steel. 10 and 10 are spanned between wooden pillars 11 and 11, and both ends thereof are attached to both sides of the pillars 11 and 11 so as to sandwich the pillar 11, and are joined to the pillars 11 and 11 by a plurality of bolts 12. ing.

  Moreover, FIGS. 11-14 shows the wooden frame | frame which uses lightweight H-shaped steel as a steel beam, the steel beam 10 is spanned between the wooden pillars 11 and 11, and the both ends are between the pillars 11 and 11. FIG. Are joined by T-shaped metal piece 13, L-shaped metal piece 14, or U-shaped metal piece 15, respectively.

  As shown in FIG. 11, the T-shaped hardware 13 is attached to the side surface portion of the column 11 by bolting the flange 13 a to the side surface portion between the columns 11, 11 with a plurality of bolts. The end is joined to the T-shaped metal 13 by bolting the end of the web 10a of the steel beam 10 to the web 13b of the T-shaped metal 13 with a plurality of bolts.

  Further, as a method of attaching the T-shaped hardware 13 to the pillar 11, as shown in FIGS. 12A and 12B, a notch 13c is provided in the web 13b of the T-shaped hardware 13, and a flange is formed in the notch 13c. The bolting of 13a to the side surface of the pillar 11 is also performed.

  As shown in FIG. 13A, the L-shaped metal piece 14 is attached to the side surface portion of the column 11 by bolting one flange 14 a to the opposite side surface portion between the columns 11, 11 with a plurality of bolts. The end of the steel beam 10 is joined to the L-shaped metal piece 14 by bolting the end of the web 10b of the steel beam 10 to the other flange 14b of the L-shaped metal piece 14 with a plurality of bolts.
