A structural element (10) for forming a panel, with an upper plane (12) and lower plane (14) which are parallel and deformed along their plane at intervals by pods (16) which extrude toward the opposing plane with their internal faces mating to one another.

A voided floor panel is provided. The voided floor panel includes a pre-cast dome, strands, reinforcing bars, and a slab. The pre-cast dome includes a flange portion, stem portions, and joint portions. The strands are pre-tensioned. The reinforcing bars are inserted through rebar block-outs of the pre-cast dome. The joint portions, the strands, and the reinforcing bars are cast within the slab. The strands improve a resistance of the slab to flexure. The joint portions improve a vertical shear resistance between the slab and the pre-cast dome. The joint portions may include corrugated dovetails for further improving a horizontal shear resistance between the slab and the pre-cast dome.

The web frame is a bonded assembly of panels and porous blanket layers, separated by an arrangement of isolated spacers. The panels and spacers are covered with a bonding means. A coating covers inner surfaces of the panels and spacers. The porous blanket is compressed and pinned between these panels, by spacers that are arranged as isolated nodes or columns The spacers have sharpened ends that penetrate the blanket and connect with the opposing panel. The web frame assembly provides thermal and sound insulation for buildings and other solid objects. These web frames are lightweight, durable, and permeable. Capillaries and passages throughout the panels and fibers of the blanket allow passage of moisture and air, thereby assisting in the management of condensation within the web frame.

The invention relates to a method for manufacturing a welded component, where at least one material piece is positioned between metal pieces to be welded together. At least one protrusion (5, 13, 23, 33, 43) is achieved to at least one of the metal pieces (3, 4; 11, 12; 21, 22; 31, 32; 41, 42) to be welded together, and at least one opening (2, 14, 24, 34, 44) is achieved to at least one material piece (1, 15, 25, 35, 45) which is positioned between the metal pieces (3, 4; 11, 12; 21, 22; 31, 32; 41, 42) to be welded and isolated (16, 17; 26; 36) from the metal pieces to be welded. At least one part of the protrusion (5, 13, 23, 33, 43) in one of those metal pieces to be welded together is taken through the opening (2, 14, 24, 34, 44) in order to have mechanical contact through the upper end of the protrusion (5, 13, 23, 33, 43) with the second metal piece to be welded. Welding (37, 38, 39) of the metal pieces together is carried out by focusing the weld effect to the surface of the second metal piece which is in connection with the protrusion to the first metal piece to be welded. The invention also relates to the use of the component.
