Engagement profile or beam

A beam for use in construction for fastening to a building construction element in a bearing portion of a joint structure comprising:

• a beam-shaped member made of a substantially thin sheet metal and including:
• two side members;
• two fastening strips, each fastening strip extending outwardly in an angular position from a first edge of one of said respective side members;
• an intermediate strip extending between second edges of said side members to define a bottom of said beam-shaped member;
• said side members and said intermediate strip forming a substantially flat-bottomed V-shaped configuration;
• a plurality of fastening means being provided at said each fastening strip and substantially closely spaced along the surface of said fastening strip, said fastening means being shaped such as to penetrate into the building construction element upon pressing of said fastening strip against the building construction element for fastening said beam-shaped member to said building construction element;
• and
• at least one reinforcement member made as a separate piece and being provided on at least said intermediate strip at least in the interior of said V-shaped configuration, said reinforcement member extending in the longitudinal direction of said intermediate strip for increasing the bending strenght of said beam-shaped member, said reinforcement member being arranged across said intermediate strip to reach at least said second edges of said side members and being affixed to said V-shaped configuration or said thin-sheet metal member.
