Building construction

Claim 2

In a building unit having a plurality of panels interconnected to comprise a building module, a sandwich panel having a pair of spaced parallel surface sheets and an intermediate filler material, and a reinforcing, load-carrying framing element extending about the periphery of said sandwich panel, said framing element comprising an elongated member of generally U-shaped cross-section having spaced parallel extending leg portions and an intermediate transverse leg portion, each of said three leg portions having a wide base portion, and a flange portion mounted in outwardly-spaced-parallel relation to said base portion by a pedestal, the width of said pedestal being less than the width of said flange portion to provide clearance between the inner side of each free margin of the flange and the outer side of the base portion confronting said flange, the extending leg portions being mounted with the inner surface of said base disposed flush against the exposed surface sheet of said sandwich panel, and means to anchor said U-shaped member in place.

Claim 3

A sandwich panel according to claim 1 wherein said anchoring means comprises a bonding agent disposed between said extending leg portions and said surface sheets.

Claim 4

A sandwich panel according to claim 2 wherein said pedestal is hollow to provide a receptacle for the bonding agent on the underside of said wide base portion.

Claim 5

A sandwich panel according to claim 2 wherein the undersides of said base portions have grooves adjacent the free edge thereof to provide receptacles for the bonding agent.

Claim 6

In combination with a sandwich panel according to claim 1 a wall section adapted for connection thereto comprising an elongated member with a transverse leg portion having a wide base portion extending along the edge of the wall section, a flange portion parallel to said base portion in outwardly-spaced relation thereto, a pedestal mounting said flange portion on said base portion to provide clearance between the inner side of each free margin of the flange and the outer side of the base portion confronting said flange, means mounting said wall section adjacent said sandwich panel with the flange portion of the wall section in closely-spaced confronting parallel relation to one of the flange portions of said sandwich panel, and a pair of cover strips engaging in the clearance spaces and spanning between the edges of the confronting flanges to form an enclosed channel way having a pair of opposite sides defined by said flanges and another pair of opposite sides defined by said cover strips.

Claim 7

A combination according to claim 5 wherein each of said cover strips comprises a planar body portion and a pair of legs, each of which is adapted to snap into the clearance space between the flange and the base portion.

Claim 8

A building unit having a plurality of panels interconnected to comprise a building module, each of said panels having a pair of spaced parallel surface sheets and an intermediate filler material, a reinforcing load-carrying framing element extending about the periphery of each of said panels, said framing element comprising an elongated member of generally U-shaped cross-section having spaced parallel extending leg portions and an intermediate transverse leg portion, each of said three leg portions having undercut recesses extending along opposite sides of said leg portion along the entire length of said framing element and means mounting said framing element in telescopic engagement with said panel to overlie the marginal edges of said panels, said extending leg portions overlying each of said opposite parallel surface sheets and said transverse leg portion spanning between said parallel sheets to define the edge of said panel, and means interconnecting said panels comprising angular clip elements disposed at spaced locations along the length of said panels having one part anchored to one of said three leg portions of one panel and an angular part extending at right angles to said leg portion, a second clip member having one part firmly anchored to one of said three leg portions of an adjacent panel and another part extending at right angles thereto, said extending part of said clips being disposed in face-to-face abutting relation, and releasable fastener means interconnecting said extending parts and effecting interconnection of said panel members.

Claim 9

A building unit having a plurality of panels interconnected to comprise a building module, each of said panels having a pair of spaced parallel surface sheets and an intermediate filler material, a reinforcing load-carrying framing element extending about the periphery of each of said panels, said framing element comprising an elongated member of generally U-shaped cross-section having spaced parallel extending leg portions and an intermediate transverse leg portion, each of said three leg portions having undercut recesses extending along opposite sides of said leg portion along the entire length of said framing element and means mounting said framing element in telescopic engagement with said panel to overlie the marginal edges of said panels, said extending leg portions overlying each of said opposite parallel surface sheets and said transverse leg portion spanning between said parallel sheets to define the edge of said panel, and means interconnecting said panels comprising angular clip elements disposed at spaced locations along the length of said panels having one part anchored to one of said three leg portions of one panel and an angular part extending at right angles to said leg portion, a second clip member having one part firmly anchored to one of said three leg portions of an adjacent panel and another part extending at right angles thereto, said extending part of said clips being disposed in face-to-face abutting relation, and releasable fastener means interconnecting said extending parts and effecting interconnection of said panel members.

Claim 10

A building construction according to claim 7 wherein the panels are disposed in a hollow rectangular array to constitute a building module and including a roof structure composed of a plurality of said sandwich panels extending longitudinally across the width of said building unit, said sandwich panels of the roof structure being connected to the panels forming the wall structure by clips and fasteners, the panels of the roof structure being interconnected by a first girder member connected to the transverse leg of one roof panel and projecting perpendicularly downard therefrom, a second girder member connected to the transverse leg of the adjacent roof panel and projecting perpendicularly downward therefrom, and fastener means for connecting said two girder members in face-to-face abutting relation, said girder members longitudinally spanning the full width of the building unit.

Claim 11

A building construction according to claim 8 wherein each of said girder members has at its distal edge an angular flange extending to underlie its associated panel member, the flanges of the two girder members being aligned to provide a support structure underlying said roof.

Claim 12

A building construction according to claim 7 wherein said connecting elements include cover strips spanning between said adjacent panels, said cover strips having leg portions adapted to engage in said longitudinally extending undercut recesses of the legs of the adjacent panels to enclose the space between said panels provided by clip members.

Claim 13

A building construction according to claim 10 wherein said legs have guide grooves positioned therein parallel to said channels in a position to be exposed adjacent said cover strips when said cover strips are properly engaged in said channels.

Claim 14

A building construction according to claim 11 wherein said cover strips are formed of a resilient material to permit the legs thereof to snap into engagement with said channels.
