Abstract
Abstract A housing for apparatuses working in sound-absorbing, heat insulating or airtight conditions, e.g. air conditioning devices, the walls, the bottom and the ceiling of which are assembled of elementary, self-supporting insulation plates giving the whole housing a rigidity and good carrying capacity, each plate comprising two parallel metal sheets arranged at a distance from each other the rims of which are pressed together and bent as to form a shank and a channel, the metal sheets defining an interior space therebetween. According to the invention the shanks of two adjacent insulation plates serve on one hand for connecting the plates and on the other hand as a support of an insulating means, the interior space of each plate being completely filled with a hard porous material consistently connected with the inside surfaces of both the metal sheets.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
159 words
In a sound-absorbing, heat insulating or airtight housing for apparatuses, the walls, the bottom and the ceiling of which are assembled of elementary self-supporting insulation plates, each plate comprising two parallel metal sheets arranged at a distance from each other defining an interior space therebetween, the rims of said sheets being pressed together and bent on each side of the plate as to form a shank and a channel, the shanks of two adjacent plates serving for connecting both plates together, the improvement wherein the shanks and the channels of each plate lie within a space defined by planes extending through both said metal sheets, and the shanks of two adjacent plates serve as a support of an insulating means, wherein the insulation means is a soft porous material filling out a space formed at a jointure of adjacent plates, said material being covered from the outside by a cover lid aligning with the outside surfaces of the plates.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
37 words
A housing as defined in claim 1, wherein the insulation means is pressed on said shank by said cover lid in such a manner as to form an airtight seal between the shank and the cover lid.
Claim 4
Dependent Claim
35 words
A housing as defined in claim 1, wherein the cover lid includes a rim which is adapted to be positioned between a reinforcement angle fixed on said shank and a surface segment of the plate.
Claim 5
Dependent Claim
22 words
A housing as defined in claim 3, wherein the cover lid is coextensive with a length of a surface of said plate.
Claim 6
Dependent Claim
61 words
A housing as defined in claim 1, wherein said cover lid includes reset end portions and said reset end portions of a plurality of said cover lids are positioned adjacent at an intersection of a plurality of plates, said adjacent lids are covered by a cover cap aligned with the surfaces of said plates and fastened to said plates by bolts.
