A beam reinforcing metallic material includes a welding surface, a counter-flange-part surface, a contacting surface, a protrusion, and the like. The beam reinforcing material is a member that is made of metal such as steel for example. The beam reinforcing metallic material is not plate shaped but has a three dimensional shape. More particularly, the cross-sectional shape varies from the edge parts toward the center part in longitudinal direction. The cross section (cross-sectional area) of the center part of the beam reinforcing metallic material in longitudinal direction is larger than the cross sections (cross-sectional areas) of the both end parts. Increasing the cross-sectional area of the vicinity of the center part of the beam reinforcing metallic material allows the part that receives maximum stress to securely obtain the flexural strength when the beam reinforcing metallic material is fixed to the beam.

Beam reinforcing metallic material and beam reinforcing structure

A beam is an H-shaped steel having flange parts above and under a web part. A through hole is formed on web part to let pipes and the like pass through. A ring beam reinforcing metallic material is disposed through hole. A beam reinforcing metallic material is disposed along the upper and lower flange parts at positions away from the through hole. The beam reinforcing metallic material on the front surface of the web part (opposite side of a flange of the ring beam reinforcing metallic material). The beam reinforcing metallic material in a direction in which a counter-flange surface of the beam reinforcing metallic material faces the flange part. A contacting surface is in contact with web part and is fixed to the web part with a welded section. At this time, the welded section is formed up to the height to which an angle varying part is covered.
