PROFILED MEMBER MADE OF LIGHT-WEIGHT ALLOY THAT IS CONNECTED TO ANOTHER PROFILED MEMBER, METHOD FOR CONNECTION WITH SIDE WALLS OF TWO PROFILED MEMBERS, DECK AND BEAM MADE BY MEANS OF JOINING PROFILED MEMBERS

摘要

The invention relates to a light alloy profiled member that is to be laterally joined to another profiled member and comprises at least one raised longitudinal flange (1), at least one longitudinal groove (2) having a complementary cross section, or both. The inventive profiled-member is characterized by the fact that the cross sections of the flange (1) and groove (2) are cone-shaped and are provided with indentations (3) having negative clearance. The inventive profiled members make it possible to produce very wide floors and girders.
