Abstract
Abstract A structural unit body comprises an outer flange extending outwardly from the edge of a box-like frame plate and an inner flange extending inwardly from the other edge. A stuffed box is secured by anchoring means to the inner flange, such stuffed box being made of dampproof material covered with a metal net and stuffed with noncombustible materials of mineral or inorganic fibers. Cement mortar is applied to the frame plate, inner flange and to the metal net of the stuffed box and a circumferential groove is formed between the outer flange and the underside of the cement mortar.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
140 words
A prefabricated structural unit body adapted to be affixed to a structural member comprising a four sided frame with each side having a frame plate along with an outer flange and an inner flange, said outer flange extending outwardly and said inner flange extending inwardly from said frame plate, said inner flange circumscribing an opening in said frame, a stuffing box, a noncombustible material within said stuffing box, anchoring means securing said stuffing box to said inner flange to thereby close said opening, cement mortar disposed on at least portions of said stuffing box and said frame, said cement mortar being disposed relative to said outer flange so as to form a circumferential groove between said cement mortar and said outer flange, whereby said groove provides access to said outer flange to facilitate affixing the latter to said structural member.
Claim 2
Dependent Claim
140 words
A prefabricated structural unit body adapted to be affixed to a structural member comprising a four sided frame with each side having a frame plate along with an outer flange and an inner flange, said outer flange extending outwardly and said inner flange extending inwardly from said frame plate, said inner flange circumscribing an opening in said frame, a stuffing box, a noncombustible material within said stuffing box, anchoring means securing said stuffing box to said inner flange to thereby close said opening, cement mortar disposed on at least portions of said stuffing box and said frame, said cement mortar being disposed relative to said outer flange so as to form a circumferential groove between said cement mortar and said outer flange, whereby said groove provides access to said outer flange to facilitate affixing the latter to said structural member.
Claim 3
Dependent Claim
18 words
A structural unit body according to claim 1 wherein said frame is an integrally formed metal, box-like structure.
Claim 4
Dependent Claim
33 words
A structural unit body according to claim 1 wherein said stuffing box is made of a dampproof material, a metal net-like material covering said dampproof material, said noncombustible material being a fibrous material.
Claim 5
Dependent Claim
80 words
A structural unit body according to claim 3 wherein said mortar cement is disposed over and fixed to said metal net-like material and said inner flange, said mortar cement also being disposed on and fixed to a portion of said frame plate which is most closely adjacent to said inner flange, said mortar cement extending to form an edge disposed between said inner flange and said outer flange, said circumferential groove being defined by said edge and said outer flange.
Claim 6
Dependent Claim
22 words
A structural unit body according to claim 1 wherein said frame plate is provided with means defining a plurality of spaced openings.
Claim 7
Dependent Claim
17 words
A structural unit body according to claim 1 wherein said frame is an assembled, metal box-like structure.
Claim 8
Dependent Claim
108 words
A structural unit body comprising a frame having an outer flange and an inner flange, said inner flange circumscribing an opening in said frame, said outer flange being in the form of a U-shaped and box-like configuration, a buffer material disposed within said box-like configuration, a stuffing box, a noncombustible material within said stuffing box, anchoring means securing said stuffing box to said frame to thereby close said opening, cement mortar disposed on at least portions of said stuffing box and said frame, said cement mortar being disposed relative to said outer flange so as to form a circumferential groove between said cement mortar and said outer flange.
Claim 9
Dependent Claim
108 words
