The tenon 22 of the column 20 is fitted and engaged from the opening 12A of the tenon groove 12 of the base 10. The reason why the tenon groove or tenon is not processed or formed in the entire width direction in the base 10 or the column 20 is to lock one end of the tenon 22 when the tenon 22 is fitted and engaged with the tenon groove 12. .
[0010]
FIG. 3 is a schematic perspective view of the cross member bracket 40.
As shown in the figure, the crosspiece metal fitting 40 includes a joist fixing portion 41 for fitting and fixing the joist 30 and a base abutting portion 42 that comes into contact with the base 10. The joist fixing part 41 is formed in a concave shape in accordance with the vertical and horizontal dimensions of the joist 30, and the side part 41 </ b> A has three bolt holes 411 for connecting the joist 30 to the left and right, respectively, for a total of six. The place is provided. Further, the base abutting portion 42 is formed with a notch 43 that matches the external shape of the mortise groove 12 that is grooved in the base 10.
[0011]
Hereinafter, based on FIGS. 4-6, the reinforcement procedure of a pillar (longitudinal material) is demonstrated.
First, as shown in FIG. 4, the notch 43 provided in the base contact portion 42 of the cross member receiving metal fitting 40 is aligned with the mortise groove 12 of the base 10. Next, as shown in FIG. 5, the column 20 is positioned beside the base 10, and the tenon 22 of the column 20 is fitted and engaged from the opening 12 </ b> A of the tenon groove 12 of the base 10. Since the tenon groove 12 and the tenon 22 are not processed and formed in the entire width direction, the tenon 22 is locked at the end of the tenon groove 12 when the tenon 22 is fitted and engaged with the tenon groove 12. Then, as shown in FIG. 6, the joists 30 are fitted into the recesses of the cross member receiving metal fitting 40. At this time, the end portion of the joist 30 comes into contact with the fitting portion of the tenon groove 12 and the tenon 22, and the column 20 is suppressed.
