DE1658920C - Insulation board covered on both sides - Google Patents

Description

The invention relates to an insulating board made of rigid Lightweight material, in particular foam plastic, which is made of a flexible sheet on both sides, for example Cellulosic material, is covered.

Such insulation panels are preferably used as thermal protection. When installing each plate must individually handled and fastened. This requires a lot of working time.

The object of the invention is to propose an improved insulation board covered on both sides bring, which is foldable in the shape of an accordion, in particular to facilitate laying. This task is achieved according to the invention in that the insulation board is elongated and provided with transverse beads that allow an accordion-like folding. Although it is known per se, a stiff insulation layer to be formed from strips that are folded in the shape of an accordion (German utility model 1 838 894), however, it is disadvantageous that the production of the well-known insulation strips, in which, by the way, a cover is not provided, is relatively complex and expensive.

The insulation board according to the invention thus combines the advantages of the various known insulation boards, without their disadvantages having to be accepted. Despite the double-sided cover An accordion-shaped folding is possible through separate cover layers. Advantageous is here that the manufacturing costs are relatively low, because the Isolierverkletdung according to the invention can be produced in such a way that long sheets, which have the aforementioned sandwich construction, passed through an embossing machine to produce the beads.

The insulation boards according to the invention, which can be laid very easily and quickly, are special Advantageously used for cladding and stiffening the walls of caravans, also here there is the advantage that the production and installation costs can be kept very low.

According to a preferred embodiment, the transverse beads are alternately on and on the other side of the plate arranged. The Quersicki " but can start of this also arranged opposite one another on both plate sides

It is recommended that the longitudinal edges of the panels have folds, preferably also produced by embossing to be provided so that adjacent plates can overlap. This results in si. , the advantage of a consistently good Abdichiui and also the advantage that despite the butt joints d. adjoining sheet-like plates em continuous smooth surface is achieved.

The invention thus represents a very simple one in ,,: An expedient solution to the problem is a duid-going plate, jus a stiff and fesu Material exists to make it foldable, namely so that separate elements are required for this. as with the known foldable insulation, and without a break or other destruction di Structure when folding occurs.

The insulation board according to the invention can beispk-K wise to reinforce the expansion of a caravan - be used.

A preferred exemplary embodiment of the invention is explained in more detail with reference to the drawing 1; indicates

Fig. 1 is a plan view of a part of an inventive Insulation board,

Figure 2 is a cross section taken along line 2-2 in

Fig. 1,

F i g. 3 is a side view of a part length of an inventive A modified version of the insulation board, which is folded in the shape of a monika.

In the insulation board shown, a layer of a thermoplastic foam plastic 1 is between two webs 2 of cellulose material embedded. The choice of the appropriate cellulosic material depends on various circumstances, but mainly on cost. For this reason it is preferred Paper used. The paper used can be made in a variety of ways and be water-repellent if necessary. The impermeability to water of the insulation board according to the invention comes from the foamed inner layer, so that it is practically possible to use untreated Paper to use.

After the sandwich construction has been made the insulation board is passed through a series of pressure rollers or other suitable devices, to incorporate the required beads. One side of the insulation board faces the Longitudinal edges folds 3 and 3 ', which serve to facilitate the installation of the insulation board. At the Installation, for example in a caravan, a fold 3 of an insulation board overlaps the adjacent fold 3 ' the next (reversed) insulation board and in this way creates a good seal between adjacent insulation boards.

Transverse beads 4, 5 are provided perpendicular to the longitudinal extension of the folds 3, 3 ', which according to FIG. 3

lie alternately on the top and bottom of the insulation board. These transverse beads are in the same Spaced along the length of the insulation board and allow compact folding like an accordion. In Fig. 3 the Dämmpl? Ue is shown in loose accordion fold. By using compressive forces acting on the ends, the insulation board can be made compact fold, with the surfaces lying between the transverse beads resting against one another. In this form is the Insulation board ready for installation. The insulation board is expediently tailored to the individual types of use tailored. In particular, the insulation board will be the exact length of the house or adapt the caravan it is intended to expand. The attachment takes place on the Way that the insulation board, for example. On the roof structure is hung up and the worker for rtschr.-itend the Unfold the insulation board and at the same time use the edges by netting or some other type of fastening connects to the roof structure. Experience has shown that the insulation board according to the invention up to
