An improved composite sandwich panel and wall system enhances assembly of prefabricated components to form both a secure and uncomplicated wall structure.
1. A wall system comprising
a composite sandwich panel ( 6 ) comprising an inner board ( 1 ) formed of rigid insulating material and having a notch or channel ( 5 ) extending around a periphery thereof, and an outer board ( 4 ) laminated to the inner board ( 1 ),
a channel sill ( 13 ) configured to receive the composite sandwich panel ( 6 ),
hollow steel structural tubes ( 7 , 8 ) configured to vertically and horizontally abut the composite sandwich panel ( 6 ) when the composite sandwich panel ( 6 ) and vertically-arranged structural tube ( 7 ) are received in the channel sill ( 13 ),
wherein the horizontally-arranged structural tube ( 8 ) comprises endplates ( 9 , 10 ) welded to opposite ends thereof,
a stepped washer ( 12 ),
a bolt ( 11 ) configured to secure the stepped washer ( 12 ) to the vertically-arranged structural tube ( 7 ),
one ( 10 ) of said endplates ( 9 , 10 ) comprising a keyhole configured to slide over the stepped washer ( 12 ) to be secured to the respective vertically-arranged structural tube ( 7 ), and
an opposite endplate ( 9 ) of said endplates ( 9 , 10 ) having a rounded hole configured to receive the keyhole of another endplate ( 10 ).
2. The wall system of claim 1 , additionally comprising
a scrim ( 2 ) laminated to at least one side of the inner board ( 1 ).
3. The wall system of claim 2 , additionally comprising
an adhesive ( 3 ) laminating the scrim ( 2 ) to the inner board ( 1 ).
4. The wall system of claim 3 , wherein the scrim is laminated to both sides of the inner board ( 1 ) with the adhesive ( 3 ) and two outer boards ( 4 ) being laminated to opposite sides of the inner board ( 1 ).
5. The wall system of claim 1 , additionally comprising a tongue insert ( 15 ) configured to be inserted into the notch or channel ( 5 ) of the inner board ( 1 ).
6. The wall system of claim 1 , wherein the vertically-arranged structural tube ( 7 ) comprises a series of pre-drilled holes, and additionally comprising a set of bolts ( 14 ) configured to attach the vertically-arranged structural tube ( 7 ) to the channel sill ( 13 ).
