Oblique beam metal connector and beam-connecting structure

[Problem] To provide: an oblique beam metal connector suitable for obliquely connecting beams together while also making use of a conventional beam-receiving metal fitting; and a beam-connecting structure employing said oblique beam metal connector. [Solution] An oblique beam metal connector 5 is equipped with: a beam-splicing section 51; a corbel section 52 that protrudes out from an appropriate intermediate position of the splicing section; and a beam-receiving metal fitting attachment section 53 that extends, from a distal end edge of the corbel section, in an inflected manner at an orientation forming a predetermined plane angle. The beam-splicing section 51 of the oblique beam metal connector 5 is spliced to a side surface of a strong-side beam 2, and fastened to a side surface of the beam 2 by through bolts 45, 46 that penetrate through the beam 2 in the beam width direction. A slit 61 is formed on an end part of an oblique beam 6, and a beam-receiving metal fitting 1 is attached thereto. An abutting section 12 of the beam-receiving metal fitting 1 is overlaid onto the beam-receiving metal fitting attachment section 53 of the oblique beam metal connector 5, and the foregoing are fastened by nut and bolt to one another .
