The innovation concerns a pair of insulating holding shells according to the preamble of claim 1 =

Well-known pairs of insulating half-shells of the angry kind are designed as separate pieces - the outer protective jacket unfolded by hand, the two insulating half-shells are inserted, and it Finally, the manifold insulation consisting of these three elements is applied to the relevant Elbow pushed. The protective jacket has so much elasticity that the two insulating half-shells at least lie loosely with a certain form fit against the pipe elbow, so that finally the seam of the protective jacket can be glued with an adhesive strip or by brushing on acetone can.

In the interest of universal applicability, the inner surface profile of the insulating half-shells is like this designed that an application in connection with conventional heating pipe elbow pieces (relatively narrow radius of curvature), drawn heating pipe elbows (relatively large radius of curvature), as well as three different types of screwable Water pipe fittings can be used. When pushing on a pipe bend is therefore «Do not wipe the inner surfaces of the insulating half-shells and the pipe exactly, so that the insulating half-shells even when pushed over

outer protection within the same one have some ability to move. This has the consequence that the end faces of an insulating half-shell not necessary flush with the corresponding end faces of the other insulating half-shell have to stand. Whether the front surfaces are flush or not cannot be checked from the outside either Because the material of the protective jacket is mostly opaque. This in turn can lead to that between the end faces of an insulating half-shell pair and the adjoining end faces of the insulating half-shells of a straight pipe section, empty spaces and thus cold bridges arise because the The insulating effect of the protective jacket is relatively low.

By carefully working when pushing on the two insulating half-shells with the protective jacket Although these disadvantages can largely be avoided with the pipe elbow, this is possible with one correspondingly higher expenditure of time, which is normally not driven by an insulation tradesman will. In addition, the outer protective jacket against the pair of insulating half-shells has a certain ability to rotate around the common axis of curvature. This in turn leads to the fact that the overhang of the protective jacket over one end face of the pair of insulating half shells is greater than over the other end face, so that the overlap of the protective jacket over an adjacent The end of a protective jacket on a straight piece of pipe is too small. If you move the protective jacket rather in a correct position, this in turn can result in an undesirable mutual

Shift of the vöii deff. Protective coat Aimgebenen Isolation half-aches occur *

The problems explained above only occur with the insulation of pipe elbows, not however, from straight pipe sections to »because the latter pairs of insulating half-shells are known which are connected to one another at one dividing line by a hinge strip »Often are also the pairs of insulating half-shells for straight people Pipeline sections already provided with a laminated outer protective jacket so that also no problems due to a relative shift between the protective jacket and the pair of insulating half-shells may occur. In the case of pipe elbows, however, no technical solution is known yet which the above-mentioned problems can be solved in a satisfactory manner without this is due to the excessively careful work and the corresponding expenditure of time on the part of an insulation craftsman requires.

The task of the furnace is to create a pair of insulating half-shells that is better than the prior art together with a protective sheath for the sheathing of pipe elbows, which is flush of the end faces of the pair of insulating half-shells after being pushed onto a pipe elbow is ensured and, in addition, there is also the possibility of the protective jacket against the Pair of insulating half-shells in industrial prefabrication to secure against a relative shift. This is achieved through the characteristic features of claim 1 =

Outer parting it is achieved that the insulating half-shell pair within the protective jacket together with the the latter without any relative shift apart and after being pushed onto a Hohrleitungskrümmsr can also be closed again. The flush of the both end faces of the insulating half-shell pair is always guaranteed. But there is still more the possibility of using the pair of insulating half shells during industrial prefabrication within the To fix the protective sheath with a pin, which penetrated radially from the outside through the protective sheath is and penetrates the hinge web of the insulating half-shell pair. This pin cannot be used when opening the protective jacket and the pair of insulating half-shells it contains be uprooted.

The insulating half-shells 1, 1 'shown in Fig. 1 have a conventional profile and are on Pipe elbows of various types can be used, as already mentioned above in the introduction to the description was set out in the explanation of the prior art. The peculiarity of the illustrated Isolierhalbschalenpaares consists only in that both insulating half-shells 1, 1 'on their both outer vertices and there in the area of a later axial half-shell contact plane (at 1 coinciding with the plane of the paper) in one piece by a thin one Hinge web 2 are connected to one another.

The pair of insulating half shells 1, 1 'is already at the industrial prefabrication in a protective jacket 3 (Fig. 3 and 4) inserted.
