US Patent 11591789 Foldable building structures with utility channels and laminate enclosures

An enclosure component having a thickness for a building structure having an interior sheathing layer comprising paper; a first structural layer bonded to the interior sheathing layer and comprising a first generally rectangular structural panel of magnesium oxide arranged in a side-by-side relationship with a second generally rectangular structural panel of magnesium oxide to define a first structural panel seam between the first and second structural panels. There is a first binding strip of magnesium oxide positioned over the first structural panel seam and fastened to form a lap joint with the first structural panel and with the second structural panel, so as to bond together the first and second structural panes. The enclosure component includes a first strengthening layer, comprising woven fiber mat, bonded to the first structural layer; and a foam layer with first and second opposing faces comprising a first generally rectangular foam panel and a second generally rectangular foam panel arranged in a side-by-side relationship to define a foam panel seam between the first and second foam panels. The first structural panel seam is offset from the foam panel seam a select distance in a direction generally perpendicular to the thickness. The first strengthening layer is bonded to the first opposing face of the foam layer. The enclosure component also has a second structural layer comprising a third generally rectangular structural panel of magnesium oxide arranged in a side-by-side relationship with a fourth generally rectangular structural panel of magnesium oxide to define a second structural panel seam between the third and fourth structural panels. There is a second binding strip of magnesium oxide positioned over the second structural panel seam and fastened to form a lap joint with the third structural panel and with the fourth structural panel, so as to bond together the third and fourth structural panels. The second structural panel seam is offset from the foam panel seam a select distance in a direction generally perpendicular to the thickness; and the second structural layer is bonded to the second opposing face of the foam layer.
