Prefabricated building panels
First Claim
1. A prefabricated building panel comprisinga plurality of longitudinally extending transversely spaced trusses,each truss comprising opposed bases and an intervening portion extending between the bases,a first sheet and a second sheet fastened to one of said bases,insulating material between said sheets,said first sheet comprising a plurality of transversely spaced grooves defined by transversely spaced narrow ribs extending longitudinally and formed by closely spaced portions of the first sheet bent inwardly,said grooves having a base wall and a side wall width substantially equal to the width of one of the bases of the truss and receiving one of the bases,the base of each groove lying in the plane of the sheet and the width of said ribs being substantially less than the width of said grooves such that the overall appearance of the exterior of said first sheet appears to be planar and substantially uninterrupted except for narrow lines defined by the space between the closely spaced portions of the ribs and such that the space between adjacent bases is maximized for receiving insulating material.

Abstract
A prefabricated building panel comprising a plurality of longitudinally extending transversely spaced trusses, each truss comprising opposed channel members and undulating truss member joined to and extending between the channel members and an outer sheet and an inner sheet fastened to said channel members. The inner sheet comprises a plurality of transversely spaced grooves defined by narrow ribs extending transversely and formed by spaced portions of the inner sheet bent inwardly. The grooves have a width substantially equal to the width of the channel members of the truss and receiving one of the channel members. The base of each groove lies in the plane of the sheet such that the space between adjacent channels is maximized for receiving insulating material.

7. A prefabricated building panel comprising
a plurality of longitudinally extending transversely spaced trusses, each truss comprising opposed channel members and an undulating truss member joined to and extending between the channel members, a first sheet and second sheet fastened to said channel members, insulating material between said sheets, said first sheet comprising a plurality of transversely spaced grooves defined by transversely spaced ribs extending transversely and formed by closely spaced portions of said first sheet bent inwardly, said grooves having a base wall and side walls defined by said groove width substantially equal to the width of the channel members of the truss and receiving one of the channel members, the base of each groove lying in the plane of the sheet and a single side wall extending inwardly, the grooves at one end of said inner sheet being the mirror image of the other end of said inner sheet, such that the space between adjacent channels is maximized for receiving insulating material.

13. A prefabricated building panel comprising
a plurality of longitudinally extending transversely spaced trusses, each truss comprising opposed bases and an intervening portion extending between the bases, a sheet fastened to one of said bases of said trusses, said sheet comprising a plurality of transversely spaced grooves defined by transversely spaced narrow ribs extending longitudinally and formed by closely spaced portions of the sheet bent inwardly, said grooves having a base wall and a side wall width substantially equal to the width of one of the bases of the truss and receiving one of the bases, the base of each groove lying in the plane of the sheet and the width of said ribs being substantially less than the width of said grooves such that the overall appearance of the exterior of said first sheet appears to be planar and substantially uninterrupted except for narrow lines defined by the space between the closely spaced portions of the ribs, transverse cap members fastened at each end of said panel connected to said sheet and said trusses.
