Isolation of a pipe sleeve * made of insulating material and a protective jacket on sheet metal

The invention relates to an insulation ait a

and a protective jacket made of sheet metal;

Tube sleeve made of insulating material r Rohrhüleen aue Isolier = Material are used many times in rice, cooling and ventilation systems

used. The sleeve can either be around an inner tube laid - or be self-supporting. The insulating material of the

Sleeve is used for heat or sound insulation or as an M. Sound absorption layer. For ventilation systems where they

is primarily used for sound absorption, the sleeve can be used as a be designed as a self-supporting tube.

The insulation according to the invention is characterized by the protective jacket
from the fact that> is made up of two identical half-halves, each provided with two sieve edges open to the same side, so that they interlock positively during assembly, whereby two half-shells are placed around the sleeve made of insulating material, with the half-shells slightly engaging the sleeve Press together so that the Sioks remain in contact with one another as a result of the reaction force of the insulating material acting radially outwards. Since both half-shells are the same, the sheet metal jacket is cheap to manufacture and also easy and quick to assemble.

FIG. 1 shows a half-shell 1 of an elneeSohutzaantels. He Ib consists essentially of a semicircular bent sheet metal * part 2 old two slick edges 3 and V. Both slick edges are on the same page and «was (in the drawing) after right and open at the top. The length L of the semi-ech & le Is adapted to the respective purpose. It is between 0.5 and 2 meters. FIG. 2 shows a sleeve 5 Insulating material that is surrounded with protective material. BIe For example, HUIee 5 is made up of glass fibers that pass through an impregnation aue plastic are held together. the Sleeve is slotted at 6. Without inner tube, as with Flg. 2 shown, the sleeve as an Amichlussrohr between a Supply air duct and an * I. . intritteKaaten of a ventilation system be used. The sleeve is supported by the pipe socket on the channel and on the box and its inner wall acts sound absorbing. The sleeve gets a sufficient mechanical strength. Dexgojhntiaantel consists from two identical half-shells 1, whose bead edges% v interlock positively. The assembly is carried out by Pressing the two half-shells together, whereby the beads * interlocking edges. The insulating material, which for this purpose must be a little elastic, is compressed. The outwardly directed reaction force then holds the both bead edges in engagement.

In Figure 3, a scb.uti.aantel is left during assembly shown. The embodiment according to FIG. 3 differs from that according to FIG. 2 in that here an inner tube 8 "
