Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
133 words
A frame-work having an upwardly directed load bearing surface and a downwardly directed surface comprising: a plurality of individual lengthwise extending frame members constituted by steel sheets folded substantially in the shape of a trapezoid having an open large base directed downwardly and provided with at least one laterally extending wing, said frame members each being closed along at least part of its length by an added metallic strip at said large base; a plurality of cross-pieces secured in spaced relationship between lateral sides of said frame members and separating said frame members thus delimiting a hollow rigid cellular structure; and a Z-shaped terminal flange connected to each end of said frame members, the top thereof being a bearing portion substantially aligned with the top of said frame members for supporting a floor.
Claim 2
Dependent Claim
133 words
A frame-work having an upwardly directed load bearing surface and a downwardly directed surface comprising: a plurality of individual lengthwise extending frame members constituted by steel sheets folded substantially in the shape of a trapezoid having an open large base directed downwardly and provided with at least one laterally extending wing, said frame members each being closed along at least part of its length by an added metallic strip at said large base; a plurality of cross-pieces secured in spaced relationship between lateral sides of said frame members and separating said frame members thus delimiting a hollow rigid cellular structure; and a Z-shaped terminal flange connected to each end of said frame members, the top thereof being a bearing portion substantially aligned with the top of said frame members for supporting a floor.
Claim 3
Dependent Claim
73 words
Frame-work as set forth in claim 1, wherein cross-pieces are further provided at the end of said frame members as well as wedges shaped like said cross-pieces and having small securing plates for connection with said frame members whereby a continuous hollow girder is formed by said cross-pieces and wedges at the ends of several adjacent floor frame-works lying on a folded iron sheet having a wing closing the bottom of said girder.
Claim 4
Dependent Claim
21 words
Frame-work as set forth in claim 2, wherein some of said wedges constitute bearings for uprights connecting two successive frame-work levels.
Claim 5
Dependent Claim
19 words
Frame work as set forth in claim 2, comprising further connecting means for lateral flanges of two adjacent frame-works.
Claim 6
Dependent Claim
92 words
Framework as set forth in claim 1, further including a ribbed iron sheet supported on the upper surface of said frame members, said iron sheet having ribs which extend transversely with respect to said frame members and said sheet being provided in those parts directing their concavity upwards with packing means for connection of a floor coating, and wherein the framework further includes ceiling panels mounted on the bottom surface of said frame members and cross-pieces whereby the whole of the framework with ceiling panels and floor coating may be completely prefabricated.
Claim 7
Dependent Claim
35 words
Framework as set forth in claim 5 further including a removable protecting member means for surrounding at least said terminal flange and for covering the whole of the ceiling panels before mounting of said floor.
Claim 8
Dependent Claim
36 words
Framework as set forth in claim 1 further including a plate made of agglomerated sound absorbing material covering the top of said frame members, and a panel for carrying a ground coating supported on said plate.
Claim 9
Dependent Claim
28 words
Frame-work as set forth in claim 1, including further plates fixed under said frame-members, said plates being provided with fixing means for fixing prefabricated plates constituting a ceiling.
Claim 10
Dependent Claim
55 words
Frame-work as set forth in claim 8, wherein said plates fixed under the frame-members are made of agglomerated sound absorbing material and contain pieces made of magnetic material, cooperating with parts also made of magnetic material, at least one of said parts being a permanent magnet, and being fixed to said panels constituting the ceiling.
Claim 11
Dependent Claim
29 words
Frame-work as set forth in claim 1, wherein one of the lateral frame-members is provided with gussets and the other with lugs engaged in gussets of an adjacent frame-member.
Claim 12
Dependent Claim
32 words
Framework as set forth in claim 10, further comprising a small bar enclosed by said gussets, and wherein lugs delimit a resilient folded edge engaging said small bar for interlocking adjacent frame-works.
Claim 13
Dependent Claim
28 words
Framework as set forth in claim 1, comprising two lateral frame members having in cross-section the shape of a right angled trapezoid having a large base directed downwardly.
Claim 14
Dependent Claim
74 words
Framework as set foRth in claim 1, wherein space between the upper plane and the lower plane deferred by the top and bottom of the frame members and associated cross-pieces is at least partly filled with panels of absorbing material respectively arranged in parallel relationship in successive layers, said panels of absorbing material being spaced apart by spacer diaphragms, whereby a reflective effect of the sound waves is obtained together with a damping thereof.
Claim 15
Dependent Claim
45 words
Frame-work as set forth in claim 13, wherein each of the layers of the absorbing material arranged in the thickness of the frame is of equal thickness on the whole surface of the said framework, while successive layers are indifferently of same or different thickness.
Claim 16
Dependent Claim
23 words
Framework as set forth in claim 1, wherein the spaces defined between said frame members and cross-pieces are filled with an insulating material.
Claim 17
Dependent Claim
54 words
Frame-work as set forth in claim 15, wherein the insulating material is made of a mineral wool compressed on a support acting as a diaphragm and in that panels made of insulating material are stacked upon one another with said diaphragms respectively in opposed relationship from the median symmetrical plane of said floor frame-work.
Claim 18
Dependent Claim
41 words
Framework as set forth in claim 1, wherein the bearing surface of the terminal flange is underly provided with an absorbing insulating wedge thus preventing transmission of sounds from the floor supported on said framework to a structure supporting said framework.
