This substructure is based on a frame of aluminum profiles as vertical battens mechanically anchored to the slabs and the horizontal ones fixed to the vertical frame or directly to the enclosure. The vertical profiles (40x40x2 mm tube) have the mission of collecting the loads received by the horizontal profiles and transmitting them to the enclosure through brackets (support -slabs- and retention) that are attached to the wall by means of a fixing anchor and to the profile vertical by means of the union pin or self-drilling screw.
The mission of the horizontal profiles (double horizontal) is to collect the load transmitted by the plates (own weights and wind actions), these profiles are simply fixed on the vertical profiles with self-drilling screws. A pin joint (horizontal joint) has been designed, whose mission is to transmit the shear forces and allow the free expansion of the material, said joint will be made close to the meetings of vertical and horizontal profiles.
