Abstract
Abstract This invention relates generally to building construction and more particularly to a prefabricated structural unit body offering protection against fire, which is heat and soundinsulating, which has elastic properties and which is durable, and to a structural body built up by connecting such structural unit bodies. The structural unit body comprises a first frame body and a second smaller frame body forming a stepped frame body and joined to an assembly unit which includes a felt-like material a dampproof material, and a net-like material. The prefabricated unit body is used for building walls, partition walls, floors, ceilings, and the like.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
164 words
A prefabricated structural unit body having heat-resistant, sound-resistant, and moisture barrier properties comprising a first frame body, a second frame body joined to said first frame body, common openings in said first and second frame bodies, said second frame body being smaller than said first frame body and being arranged on the latter to form a step and thereby dfine a stepped frame body, a planar base material, a felt-like material disposed on said planar base material, a dampproof planar material disposed over said felt-like material, a metllic netlike material disposed over said dampproof planar material, fasteners extending between said planar base material and said metallic net-like material for fastening said materials together to thereby define an assembly unit, and means joining said assembly unit to said stepped frame body, said assembly unit being larger than said second frame body, whereby there is formed a circumferential groove defined by said step on said stepped frame body and the outer portions of said assembly unit.
Claim 2
Dependent Claim
164 words
A prefabricated structural unit body having heat-resistant, sound-resistant, and moisture barrier properties comprising a first frame body, a second frame body joined to said first frame body, common openings in said first and second frame bodies, said second frame body being smaller than said first frame body and being arranged on the latter to form a step and thereby dfine a stepped frame body, a planar base material, a felt-like material disposed on said planar base material, a dampproof planar material disposed over said felt-like material, a metllic netlike material disposed over said dampproof planar material, fasteners extending between said planar base material and said metallic net-like material for fastening said materials together to thereby define an assembly unit, and means joining said assembly unit to said stepped frame body, said assembly unit being larger than said second frame body, whereby there is formed a circumferential groove defined by said step on said stepped frame body and the outer portions of said assembly unit.

Dependent Claim
32 words
A structural unit body according to claim 1 wherein said felt-like material is formed of fibers selected from the group consisting of glass wool, asbestos, slag wool, rock wool, and synthetic fibers.
Claim 4
Dependent Claim
18 words
A structural unit body according to claim 1 including a layer of mortar on said metallic net-like material.
Claim 5
Dependent Claim
19 words
A structural unit body according to claim 1 wherein said stepped frame body is formed as an integral unit.
Claim 6
Dependent Claim
42 words
A structural unit body according to claim 1 wherein said first frame body and said second frame body are formed separately, and means joining said first frame body and said second frame body to one another to form said stepped frame body.
Claim 7
Dependent Claim
28 words
A structural unit body according to claim 1 wherein said stepped frame body has a rectangular configuration and is provided with two openings separated by a rail element.
Claim 8
Dependent Claim
147 words
