Abstract

The insulating element is intended for use in external wall claddings of underground storeys or basements and comprises a plate formed from non-biodegradable and foamed plastic. Besides having a heat-insulating effect, the plate also assumes a draining function. In order to provide for this, the plate body 1, on the side facing the wall, has drainage recesses in the form of vertical grooves 2. The openings 3 of the drainage recesses and grooves 2 respectively are shielded in a liquid-permeable manner with a filter strip 6 made of non- woven fabric. The plate body 1 consists of extruded foamed plastic without plastic particle interspaces. <IMAGE>

X insulation element

The innovation relates to an insulating element for, in particular, the outer wall cladding of the basement Preamble to the main claim.

According to DE-OS 22 62 990 a protective panel for foundation walls is known, which corresponds to the type mentioned, but the panel consists of a relatively rigid, dimensionally stable material and on one side projections for support I against the wall or the like. to create air spaces

I between the wall and the board. The other

The other side of the board forms a drainage layer

I made of porous material, such as glass fiber mats,

I rock wool, foam plastic or the like.

i ¹ ^ the practical embodiment thus consists of the

\ whole insulating layer made of a roughly corrugated sheet metal

I molded, water-impermeable board made of, for example.

I Plastic, the drainage layer placed on it

however, the thermal insulation effect is practically non-existent, since ventilation is provided with this protective panel the foundation wall is sought.

A reference to this possible use with the proviso, then the unit to a certain extent cut in half to turn it into a wall cladding panel with a double function but neither the description and the claims nor the drawings of this US-PS refer to.

The innovation is accordingly based on the object / the insulating element of the type mentioned in this regard to improve that additional measures in terms of drainage in the isolation of the Basement walls can be dispensed with, i.e. an insulation element should be created for this purpose that is able to take on a double function with simple production and Gravel fillings for drainage or custom-made products and special laying of drainage-effective materials Elements replaced.

This task is accomplished with an insulating element of the type mentioned according to the innovation resolved what is covered in the characterizing part of the main claim. Advantageous further developments result according to the subclaims.

The solution is that the dewatering depths as a vertical one

Grooves permitting continuous extrusion are formed and that in front of the grooved surface a rot-proof filter fleece is arranged.

The new insulation element is simply counteracted with its smooth or non-profiled surface put the wall surface to be isolated, the total tile-like with such individual panels is delivered, so that the entire insulation with its drainage deepens against the upcoming Bottom is directed, but the openings are shielded liquid-permeable, what, how mentioned, with a glued on, correspondingly resistant and rot-proof filter fleece takes place as they are readily available today.

Of course, the panels will be produced in sizes that are compatible with their workability and Transportes are most appropriate, for example in sizes of 1 χ 2 m, i.e. sizes like those for building boards of all kinds are common.

With continuous extrusion it is also possible

lent to form the drainage depressions undercut in cross section, so to speak a shielding of the recess openings is also connected at the same time.

The novel insulating element is illustrated below with the aid of the drawings of exemplary embodiments explained in more detail.

They show schematically:

3 shows a horizontal section according to FIG. 2,

but with a different cross-sectional shape;

4 shows a view of several assembled insulating elements in a particular embodiment;

5 shows a plan view of the elements according to FIGS. 4 and

Fig. 6, 7 in section other embodiments of the plate body.

In the plate bodies 1 according to FIGS. 1, 2, the drainage recesses 2 are in the form of vertical extending grooves 4 formed, - the entire grooved surface 5 with a rot-proof Filter fleece 6 is covered, which can be glued, for example.

A filter effect can also be achieved by that one introduces the Entwasserungseiniefungen 2 in the form of undercut grooves 4 ', which only

are still accessible through narrow gaps or openings 3 ¹ . The use of appropriate insulation elements ultimately depends on the type of soil with which the open excavation is filled.

The plate bodies 1 are connected to the insulating wall, for example with suitable adhesives.

Furthermore, the plate body 1 in the sense of FIGS. 4, 5 at two adjacent edges with protruding flanges 7 and on the other two opposite edges with corresponding ones Recesses V be provided so that the plate body 1, as shown, assign to one another permit. Mutual gluing in these edge areas is easily possible because the grooved surfaces 5 remain unaffected.

The non-woven filter 6 may in a corresponding cut size on the respective plate body 1 in the sense of Fig. 2 to be firmly applied and to the extent a finished installable element form, whereby it is possible to provide in the sense of Fig. 5 fleece edge supernatants 6 ¹ that the during installation overlap the respective front plate body in the connection edge area so that the connection joints are also covered by the filter fleece.

Apart from this, it is also possible, first of all, the plate body 1 "naked", i.e. without To install filter fleece 6, then the entire plate body surface continuously with a filter fleece band (depending on the height of the surface, if necessary with several strips of tape).

For an embodiment in the sense of FIG. 3, the cross-sectional shape of the grooves 4 ″ shown there is only to be understood as an example. The grooves could of course also be rectangular in cross section, with however, on the drainage side, the grooves except for a gap through laterally protruding into the cross-section Web 9 are covered (see Fig. 6). Embodiments in the sense of FIG. 7, with over the grooves 4 filter-effective strips 8 are used, would be possible with the same effect.
