  • the present invention relates to a new and improved construction of a housing for apparatuses working in sound-absorbing, heat insulating or airtight conditions, the walls, the bottoms 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 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.
  • Such housings are used e.g. with airconditioning and ventilation plants or as an encasing for machines and apparatuses.
  • the hereto known housings for apparatuses being used in aninsulated space comprise a frame construction on which insulation plates are screwed. It is evident that such housings with screwed-on insulation plates cannot be wholly airtight. Besides, the frame construction which is usually made of metal sheet is in no way sound-absorbing or heat insulating, even when during the assembly an elastic seal means is inserted between the plate rims which are formed as shanks and the reset frame rims.
  • Another known housing does not comprise any frame construction, however the assembling of such a housing is time consuming, as it will be described later; besides many assembly parts are needed.
  • the inside and outside ledges of the walls and the ceiling there are inserted insulation elements, whereafter the ledges are mounted from the outside of the walls and the ceiling.
  • the inside and outside ledges are then screwed together by means of bolts.
  • the transition parts between the bottom and the wall and between the wall and the ceiling have to be sealed separately.
  • Another significant object of the present invention aims at overcoming the above-explained drawbacks by providing a housing consisting of a minimum number of construction elements, with which housing an effective insulation of the closed space can be achieved; besides the housing should have a good carrying capacity.
  • the inventive housing is manifested by the features that the shanks of two plates serve on one hand for connecting the plates and on the other hand as a support of an insulating means and that the interior space of each plate is completely filled with a hard porous material consistently connected with the inside surfaces of both the metal sheets.
  • FIG. 1 is a longitudinal sectional view of two plates arranged perpendicularly to each other with an insulation means and a cover lid, which plates are used for construction of a housing for apparatuses working in sound-absorbing, heat insulating or airtight conditions;
  • FIG. 2 is a longitudinal sectional view of two plates arranged to each other in one horizontal plane with an insulation means and a cover lid;
  • FIG. 3 is a diagrammatic sectional view of a single plate with a reinforcement angle
  • FIG. 4 is a diagrammatic view of three cover lids which are put together
  • FIG. 5 is a diagrammatic view of an intersection of three cover lids with a cover cap
  • FIG. 6 is a diagrammatic view of the disassembled intersection point of four fiat cover lids with the cover cap;
  • FIG. 7 is an enlarged sectional view of the rim portions of an elementary insulation plate with a reinforcing rail
  • FIG. 8 is a diagrammatic view of the plate according to FIG. 7;
  • FIG. 9 is a diagrammatic view of the elementary insulation plate from another side as in FIG. 8.
  • FIGS. 1 3 and 7 9 have the same dimensions and are therefore interchangeable.
  • the plate rims are bent towards outside to form shanks 2, as it can be seen from the FIGS. 1, 2 and 3.
  • the shanks 2 of the two adjacent plates 1 which lie in one plane are so arranged that they lie closely to each other across their whole length; whereas the shanks 2 of the two adjacent plates which are arranged perpendicularly to each other, do not contact at all.
  • the two adjacent plates 1 are screwed together by means of bolts 3 and nuts 4, which bolts pass the shanks 2 and reinforcement angles 5 and 9 on both sides of the shanks 2; in this way the walls, the bottom and the ceiling and finally the whole housing will be put together.
  • Each reinforcement angle 5 placed on the inside of the shank 2 has a tongue 5a, which is adapted to be inserted in a channel 14 formed by the shank 2 and the bent rim of the sheet 1a of the plate 1, whereby its free end lies approximately 0.0788 inch from the bottom of the channel.
  • an insulating means 6, 6a which can also be profiled.
  • the insulating means 6, 6a is covered from outside either by a cover lid 7 or by a cover lid 8.
  • the cover lids according to FIG. 4 are of two different types, one of which being denoted with the reference number 7 and the other one with the reference number 8.
  • Each cover lid 7 and 8 has rims 7a and 8a which are bent inwards, so that by pushing the cover lids 7, 8 on the shanks 2, the rims 7a, 8a will snap behind the tongues 5a of the reinforcement angle 5, whereby the insulating means 6 will be force-pushed against the shank 2. This will result in an airtight seal between the cover lid 7 and 8 and the shank 2.
  • the reinforcement angles 5 are preferably placed at the corners formed by the shanks 2, so that there are at least two reinforcement angles 5 at each side of the plate 1.
  • the cover lids 7 and 8 are aligned with the upper surfaces of the plates 1 when they are assembled.
  • the fiat cover lids 8 On their shorter sides the fiat cover lids 8 have end portions 8b (see FIG. 6) which are inwardly reset and which abut against each other when they are assembled. These end portions 8b are covered by a cover cap 10 which is in alignement with the outer surfaces of the cover lids 8 and so with the outer surfaces of the plates 1. This has an aesthetical effect.
  • the cap 10 is screwed on the cover lids 8 by means of a countersunk bolt 12 which enters a small gap between the assembled cover lids 8.
  • Cover caps 11 which are screwed on the cover lids 7 by means of a countersunk bolt 12, are used to cover the ends of three cover lids 7, converging in a corner. This can be seen in FIG. 5.
  • the cover lids 7 and 8 as well as the insulating means 6 have the same length as the respective sides of the plates 1.
  • the elementary insulation plate 1 according to FIG. 7 consists of two parallel zinc metal sheets la, lb arranged at a distance from each other.
  • the four rims of the plate 1 are pressed together and bent in such a way as to form a shank 2 which is perpendicular to the surface of the plate 1.
  • a channel 14 is made between each shank 2 and the edge 10 of the metal sheet la by bending the rims.
  • the shanks 2 close an interior space between the metal sheets la, 1b which space is filled with an insulation sheet 15.
  • the plate 1 can be made more rigid by inserting pieces 13 in its corners.
  • the insulation sheet 15 consists of a hard porous material which is during the production of the plate consistently connected with the inside surfaces of both the metal sheets 1a, 1b and forms a lasting hard insulation reinforcement of the plate 1.
  • a reinforcing U-rail 16 is arranged alongside the small sides thereof.
  • the rail 16 is inserted between the metal sheets la, lb at the proximity of the rim of the plate 1 in such a way that it is held on its one side by the edge 10 of the metal sheet la and on its other side by the hard insulation sheet 15; besides, the free ends of the rail 16 are held by the flanged ends 1d of the metal sheet lb on that side of the plate 1 which faces the channel bottom 14.
  • the so formed slot serves to receive a bolt 17 which is adjustable.
  • the interior space of the rail 16 is filled with a soft porous material 21.
  • a washer 18 with a threaded hole is disposed on the free flanged ends of the rail 16 in which the bolt 17 carrying e.g. a supporting arm 19 can be screwed.
  • reveting socket 20 serves for holding apparatuses or for'securing cross and longitudinal bracings for large apparatuses.
  • a self-carrying housing with an effective insulation and a good'carrying capacity can be assembled from the prefabricated elemen tary insulation plates as required, without using a frame construction or a supporting brick work.
  • 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 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.
