Abstract
A frame supported, foam composite panel with a cladding backed by polyurethane foam bonding the cladding to the frame. The panel has a cantilevered extension projecting beyond the frame to enable the panel to overlap the outside edge of a column, beam, floor or other structure the panel is attached to. The cantilevered section may have reinforcing ribs embedded in the foam and may have a sealing material between the cantilever and the structure it overlays.
Claims19
A foam composite panel with a cantilever extension comprised of:
- a. a frame having a border and comprised of one or more frame members having a top edge, a bottom edge and two sides and said frame members are spaced a distance apart and
- b. a panel supported by said frame and comprised of a cover with polyurethane foam on it's backside adhesively bonding said frame to said cover and said panel having a continuous section continuous over said top edges and extending beyond said border to form a cantilever and
- c. said panel has one or more dropped sections between said sides and is fixed to said frame members with a sufficient adhesive bond to induce a fixed boundary condition on said panel,
- whereby said panel has a cantilever extension.
A foam composite panel with a ribbed cantilever extension comprised of:
- a. a frame having a border and comprised of one or more frame members having a top edge, a bottom edge and two sides and said frame members are spaced a distance apart and
- b. a panel supported by said frame and comprised of a cover with polyurethane foam on it's backside in a continuous section over said top edges and adhesively bonding said frame to said cover and said continuous section extends beyond said border to form a cantilever and
- c. a multitude of ribs positioned in said cantilever and embedded in said foam and
- d. said panel has one or more dropped sections between said sides and is fixed to said frame members with a sufficient adhesive bond to induce a fixed boundary condition on said panel
- whereby said panel has a ribbed cantilever extension.
A method of prefabricating a foam composite panel with a cantilever extension comprised of:
- a. fabricating a frame having a border and comprised of one or more frame members having a top edge, a bottom edge and two sides and said frame members are spaced a distance apart and
- b. positioning a cover material with it's backside up on a prepared surface and said cover has a boundary and
- c. positioning said frame over said cover's backside with at least part of said cover extending beyond said border to create a cantilever section and said cover is in a continuous section continuous crossing over said top edges and
- d. applying polyurethane foam onto said backside and said foam expands into one or more dropped sections between said sides and adhesively bonds to said cover, said ribs and said frame and fixes said panel to said frame members with a sufficient adhesive bond to induce a fixed boundary condition on said panel as supported by said frame
- whereby said foam composite panel with a cantilever extension is prefabricated.
