DE3313844A1 - Frontal shell for sound insulation and/or heat insulation of pipes and containers - Google Patents

Abstract

The subject of the invention is a frontal shell for sound insulation and/or heat insulation of pipes and containers, which is attached to the wall 1, webs or ribs 2 being arranged on the wall 1 for mechanical bracing. In order to hold an insulating material 8, wire mats 3 are laid on, and optionally fastened to, the webs 2. Spacers 4, which hold the outer shell 9 with or without interposition of resilient end pieces 6, are attached to the webs 2 through these mats 3. <IMAGE>

Description

Attachment shell for insulation and / or thermal insulation

for pipelines and containers The invention relates to an attachment shell for sound and / or thermal insulation for pipes and containers during implementation from air via large blown pipes, with webs on the pipe or container wall for mechanical Bracing and spacers for the outer shell are attached and in the Space insulation material is arranged.

Wherever air is converted via large blowers, it is necessary to the pipes and containers used for this purpose with sound and / or thermal insulation to provide. One should think in particular of smoke gas desulphurisation systems in power plants, in mining, in irrigation systems, in steel production, in heavy industry, filter systems and the like. The here used Pipes and tanks are on their walls for mechanical stiffening Rib structures or webs provided, with this stiffening if necessary Aluminum sheets, galvanized steel sheets, trapezoidal sheets via a resilient substructure or smooth or corrugated cement asbestos panels are arranged. The gap is filled with insulation material.

The main disadvantage of this known embodiment is in that the attachment of the sound and / or thermal insulation with a considerable Assembly effort is connected because the space formed by the stiffener is uneven is, so that a considerable form work is necessary for the attachment of the insulating materials is.

Furthermore, a lot of insulation material is consumed because the material must be guided around the individual ribs or webs.

Another major disadvantage is that the sound insulation, especially in the lower frequencies, much lower, often insufficient is.

The invention is based on the object of such a facing shell to train in such a way that an acoustic improvement of the construction is achieved and at the same time a considerable simplification of the assembly is achieved.

This object is achieved according to the invention in that the Abstancishalter are attached to the outside of the webs and that the insulation material in the space between the outside of the webs and the outer shell is arranged.

It is particularly advantageous that a metal grid over the webs is pulled to which the insulation material is attached.

It is also proposed that a steel mesh be used as the metal grid is provided.

Finally, it is advantageous that between the outer shell and the Rbstendshalter spring elements are arranged.

The invention has the significant advantage that the sound insulation is improved in a particularly simple manner, in particular not here additional insulation material must be used. For the arrangement of the insulating material Can be achieved a uniform surface, so that any special Formwork for attaching the insulation material is not required. Therefor DSmmaterial can also be saved, for example by not using the insulating material must be guided around individual ribs in the context of Aipyi constructions0 The improvement The form of # '-. lung results from the fact that on the wall of the Pipeline or the container remains an air space and continues to do so, # deß the spacers are attached directly to the outside of the webs.

The invention is in the following description based on a Ausführungsbeisplels shown in the drawing erlau, tert.

1 shows a plan view of part of a container or a pipeline and FIG. 2 shows a section along the line A-A in FIG Design shown in the drawing of the wall 1 of a container or a pipeline is provided with L-shaped webs 2 for mechanical stiffening, which are attached to the wall 1 are welded in place. A metal latticework 3 is laid on these webs 2, fabricated steel mesh mats or wire mats are particularly advantageous here get embarrassed. Wei # rhin 2 spacers 4,4 'are placed on the webs, with the holder 4 is welded to the corresponding web 2, for example, while the spacer 4 'is screwed to the corresponding web 2. On the spacers 4,4 '5 resilient end pieces 6 are attached with the interposition of combing disks, which are attached to supports 7 which hold the overlapping outer shells 9.

The outer shell 9 is provided with seals 10 at the overlaps. The space 11 between the outer shell 9 and the structural steel fabric mats 3 is filled with a sound or heat insulation material @ that is attached to the mats 3 and is thus securely attached.
