• the adjacent profiled element 2 here has a height greater than the second fixing zone 41 of the accessory of angle 4.
• the first portion 30 of the part for taking up the forces 3 is fixed to a sole 202 of the adjacent profiled element 2.
• the second portion 31 extends in the same plane as a transverse flank 203 of the adjacent profiled element 2
• a rail 6 is fixed to the part for taking up the forces 3.
• the rail 6 is fixed to the second portion 31 of the part for taking up the forces 3.
• the rail 6 is fixed on horseback. on the second portion 31 of the load-absorbing part 3 and to part of the transverse flank 203 of the adjacent profiled element 2.
• Rail 6 is suitable for the movement of an overhead crane (not shown).
• the force-absorbing part 3 thus allows, in this configuration, the assembly of an overhead crane.
• the assembly means used to assemble the profiled elements 2 together according to the first configuration and the second configuration, as well as the profiled elements 2 to the load-absorbing parts 3 are bolts.
• the bolts have the advantage of being removable, which makes the structure modular, the profiled elements 2 and the strain relief parts 3 reusable. Of course, it is possible to use any other removable assembly means.
• At least one profile element can be assembled according to the first configuration, on the one hand to an adjacent first profile element and on the other hand to an adjacent second profile element.
• the cross section of the profile member may be smaller than the cross section of the first adjacent profile member and larger than the cross section of the second adjacent profile member.
• a force-absorbing part can be on the one hand fixed to the profiled element and on the other hand to the first adjacent profiled element, and another force-absorbing part can be on the one hand fixed to the profiled element and on the other hand to the second adjacent profiled element.
• the present invention thus proposes a modular structure making it possible to construct fully modular, removable and reusable metal frame buildings.
• the use of the recovery part and the constitution of the profiled elements make it possible to reduce the quantity of steel in the structure while ensuring the modularity of said structure as well as the absorption of forces.
• the profiled elements available in different sections make it possible to optimize the quantity of steel in the structure.
• the profiled elements are constructed so as to allow two assembly configurations. This allows modularity in length and angle.
• the great versatility allowed by the structure of the profiled element and the return piece thus allows significant modularity in the shapes and dimensions of the building.
• the structure having the assembly characteristics presented above makes it possible to reach large spans and great heights, while covering a wide range of geographical areas in terms of structure resistance (resistance to wind, snow, etc.).
