Abstract
A sandwich-type structural panel is formed by a core of insulating material having opposing skins or face surfaces bonded to opposing planar sides of the core and defining rectangular recesses at each end of the panel. The panel is further characterized by elongated rigid stiffeners extending coextensive with the thickness of the core material and its length between the encapsulating skins. The spacing of the stiffeners is such that a point load of a fixed amount centrally applied to either planar surface or longitudinal edge of the panel generates a load deflection ratio of 1:1 between the central portion of the panel and its respective edge, thus providing a balanced efficient panel.
Claims9
A generally rectangular building panel, comprising:
- a core of plastic foam material having opposing sides and having longitudinal edge surfaces and having opposing end surfaces;
- a pair of panel stiffeners extending the entire thickness and length of the core material,
- said pair of stiffeners being symmetrically spaced-apart 2/3 w
- where w is the width of the panel;
- and,
- panel skin means bonded to the major faces of the core material and projecting a predetermined distance beyond the opposing end surfaces of the core material for forming a structural member receiving recess in the respective end surface of the panel.
A generally rectangular laminated building panel, comprising:
- a core of insulating material having longitudinal edge surfaces and opposing end surfaces;
- a pair of rigid planar panel stiffeners extending the entire thickness and length of the core material,
- said pair of stiffeners being symmetrically disposed in lateral parallel spaced relation 2/3 w
- where w is the width of the panel;
- and,
- panel skin means bonded to the major faces of the core material and projecting a predetermined distance beyond the opposing end surfaces of the core material for forming a rectangular recess in the respective end surface of the panel.
