Abstract
Abstract A horizontal beam of inverted generally T-shpaed vertical cross section supports edge portions of generally horizontal roof panels on transversely oppositely depending base flanges of said beam with a beam central web portion projecting upwardly between said panel edge portions, preferably in the form of transversely spaced vertical webs. Water proof upper layers of shape selfsustaining material are portioned over the panel upper surfaces and have edge portions which project upwardly from the panel edge portions and terminate spaced upwardly from said panel edge portions. An inverted U-shaped cap is positioned over the beam webs and has downwardly projecting leg portions transversely outwardly of the edge portions of the panel upper layers, said leg portions terminating downwardly overlying said panel upper layers. Transversely spaced webs project downwardly from the cap internally thereof and hook engage the beam webs retaining the cap and beam in assembly, with angled guides preferably being formed on the cap for guiding the beam webs into such assembly. Thus, the upwardly projecting edge portions of the panel upper layers provide water barriers internally of the cap for preventing water from flowing transversely into the assembly and downwardly along the inner edges of the panels.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
322 words
In a panel and beam roof assembly for a building structure, the combination of: a generally horizontal beam inverted generally T-shaped in vertical transverse cross section forming oppositely transversely depending generally horizontal base flanges and a central vertical web portion; generally horizontally extending roof panels depending transversely oppositely from said beam having lower face surfaces supported on said beam base flanges and edge portions terminating in edge surfaces generally transversely adjacent said beam web portion; water proof upper layers over upper surfaces of said panels of shape self-sustaining material having edge portions projecting upwardly from said panel edge portions and terminating upwardly spaced upwardly from said panel edge portions, said upwardly projecting edge portions of said water proof upper layers forming water barriers preventing water from flowing transversely inwardly of said upper layers and downward of said panel edge surfaces; a cap overlying said beam inverted generally U-shaped in vertical transverse cross section projecting upwardly from said panels and upper layers telescoped over said upper layer edge portions, said cap having downwardly projecting leg portions overlying said panel upper layers transversely outwardly of said upper layer edge portions and a connecting portion overlying said upward terminations of said upper layer edge portions; said central vertical web portion of said beam including transversely spaced, vertically elongated webs projecting upwardly into said cap; said cap having transversely spaced, vertically elongated webs extending downwardly from said cap connecting portion transversely inwardly of said upwardly projecting edge portions of said panel upper layers; fastening means retaining said beam and cap in assembly including interengaged hook portions between said beam and cap webs; and said cap including a downwardly projecting, transversely inwardly angled guide web spaced transversely inwardly from each of said cap webs positioned engageable by said beam webs during assembly of said beam and cap guiding said beam webs into said beam and cap guiding said beam webs into said interengagement with said cap webs.
Claim 2
Dependent Claim
322 words
In a panel and beam roof assembly for a building structure, the combination of: a generally horizontal beam inverted generally T-shaped in vertical transverse cross section forming oppositely transversely depending generally horizontal base flanges and a central vertical web portion; generally horizontally extending roof panels depending transversely oppositely from said beam having lower face surfaces supported on said beam base flanges and edge portions terminating in edge surfaces generally transversely adjacent said beam web portion; water proof upper layers over upper surfaces of said panels of shape self-sustaining material having edge portions projecting upwardly from said panel edge portions and terminating upwardly spaced upwardly from said panel edge portions, said upwardly projecting edge portions of said water proof upper layers forming water barriers preventing water from flowing transversely inwardly of said upper layers and downward of said panel edge surfaces; a cap overlying said beam inverted generally U-shaped in vertical transverse cross section projecting upwardly from said panels and upper layers telescoped over said upper layer edge portions, said cap having downwardly projecting leg portions overlying said panel upper layers transversely outwardly of said upper layer edge portions and a connecting portion overlying said upward terminations of said upper layer edge portions; said central vertical web portion of said beam including transversely spaced, vertically elongated webs projecting upwardly into said cap; said cap having transversely spaced, vertically elongated webs extending downwardly from said cap connecting portion transversely inwardly of said upwardly projecting edge portions of said panel upper layers; fastening means retaining said beam and cap in assembly including interengaged hook portions between said beam and cap webs; and said cap including a downwardly projecting, transversely inwardly angled guide web spaced transversely inwardly from each of said cap webs positioned engageable by said beam webs during assembly of said beam and cap guiding said beam webs into said beam and cap guiding said beam webs into said interengagement with said cap webs.
Claim 3
Dependent Claim
33 words
A panel and beam roof assembly as defined in claim 1 in which said panels are formed of composition material; and in which said water proof upper layers are formed of metal sheets.
