A beam shoe for attaching a (first) beam end-on to a load-bearing construction, especially to a second beam disposed in the same plane as the beam to be attached and running at right angles thereto, the beam shoe comprising an originally flat, one-piece, strip-like sheet-metal portion or blank, which is shaped to an upwardly open channel-shaped retaining member having a web-like rectangular bottom for bracing the beam to be attached on the beam shoe as well as two web-like, parallel retaining legs, the retaining member embracing, in assembled condition, an end portion of the beam to be attached at the underside and side faces thereof, the legs, which are bent over upwardly from the bottom at right angles and disposed along two opposite borders of the bottom, being provided with through holes for rod-like fasteners such as nails in particular in order to join the beam shoe to the beam to be attached, the inside spacing of the legs therefore being (at least) as large as (and if necessary somewhat larger than) the width of the beam to be attached, wherein a fastening flange provided with through holes for rod-like fasteners such as nails and/or screws is bent over at right angles along that longitudinal border of each retaining leg which faces the load-bearing construction (or if necessary the second beam), the fastening flange being designed to be placed with its outside face remote from the channel-shaped retaining member of the beam shoe on the load-bearing construction/the second beam and to be fastened thereto with rod-like fasteners such as nails and/or screws, and wherein the web-like bottom is reinforced by a (bottom) reinforcing flange or the like in order to increase its section modulus against sagging under relatively large load.
