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>

insulation element

The invention relates to an insulating element according to the preamble of claim 1, in particular for cladding the outer walls of basement layers. Insulation elements for plinth cladding are known, for example, from German application publication 2 262 990. Such insulation elements are increasingly used, since nowadays basement-floor rooms are also used and heated to an increasing number. For this reason, it is not only necessary to insulate the outer walls of the basement layers to make them moisture-proof, but also to take measures to provide thermal insulation of the filled foundation. This function is only partially fulfilled by the known insulation elements. If they do not have a secret ditch effect, these sheets placed very close to the wall surface to be insulated often still have to be fitted with a second layer of sheets, which is different in structure, consisting of small plastic balls glued together. Such sheets can only be foamed and made in a mold. In addition, they have the disadvantage that, due to their capillary action, they regularly absorb water and also retain this water, so that such sheets cannot be used at all or only with considerable results to provide a drying effect and simultaneous thermal insulation.

In order to provide a basement wall insulation that is effective both in the thermal insulation direction and in the waterproofing or drying direction, it is therefore necessary to manufacture, i.e. to design, and also to install two different elements. If drying elements are not desired, it is necessary to apply a gravel layer between the walls or the heat-insulating layer and the nearby lat-35 Tian, as usual, in order to achieve a proper drying effect in the basement rooms and their walls, i.e. to keep them dry.

It is therefore an object of the invention to improve an insulating element according to the species definition mentioned at the outset so that the additional measures required to achieve a drying effect when insulating basement walls are unnecessary, i.e. or special preparations and a different installation of the elements having a drying effect and which do not have any or practically no suction and water retention properties.

This object is solved according to the invention by creating an insulating element according to the species definition initially mentioned, which has the features indicated in claim 1. Preferred embodiments can be developed according to the dependent claims.

Thus, in order to achieve the set task, it is absolutely essential to use extruded and particle-free plastic, e.g. according to U.S. Pat. No. 3,751,377 or 3,960,792, because the sheet made from it has the desired properties, namely it can be continuously extruded continuously, it has practically no considering any kind of water suction and retention effect and at the same time it has thermal insulation properties. In addition, it is essential for the invention that the filter cloth is arranged along the two adjacent edges of the plate body, crossing them, and that the plate body be provided with flanges projecting from two adjacent edges and a flange-30 passage at both other edges.

The insulating element according to the invention is simply placed against the wall surface to be insulated, which is entirely lined with such separate plates, the entire insulation with drainage recesses and protective nonwoven mats 35 being directed towards a nearby floor.

The boards are, of course, sized to be suitable in terms of machinability and transport, i.e. e.g. 1 x 2 m, i.e. the size of all types of building boards normally 5, the size of the boards being determined simply by cutting the extrusion thread.

When the extrusion is uninterrupted, it is also possible to make the dewatering grooves widened in cross-section at the sides.

Admittedly, DE-A-2 272 990 discloses a protective plate for a foundation wall, which plate is a relatively rigid, shape-retaining plastic and in which the projections are located on one side of the plate against a wall or the like to form air spaces between the wall and the plate. The other side of the plate 15 forms a drainage layer consisting of a porous material such as fiberglass mat, rock wool, foam material or the like. Thus, in a practical embodiment, the entire insulating layer in this case consists, for example, of a plastic, corrugated, water-impermeable plate, a drainage layer fitted thereto and a perforated sheet metal layer fitted thereto. Apart from the considerable manufacturing costs, the drainage effect is likely to exist, but the thermal insulation effect is practically non-existent, since the ventilation of the foundation wall 25 is aimed at by means of this protective plate.

The building board according to DE-A-26 40 065 is an element which is arranged between two wall vaults and which is intended to act exclusively for thermal insulation and ventilation or for cooling. Because the building board is arranged between two wall vaults, it cannot be taken to perform the drainage effect, and additional measures would have to be taken outside the other wall vault to achieve the drainage effect.

The prefabricated concrete element according to DD patent publication 70 169 is not designed for cladding the foundation wall or intended for the drainage effect, but its function 4 75628 is to provide heat-insulating walls, e.g. for cooling plants, sheds, etc. when using the frame construction method.

The insulating element according to the invention is explained below by means of a drawing made on the basis of examples taken from different embodiments. The drawing shows diagrammatically: Fig. 1 a perspective view of two side-by-side plate-like insulating elements, Fig. 2 a horizontal section along the line II-II 10 in Fig. 1, Fig. 3 a horizontal section according to Fig. 2 with a different cross-sectional shape, Fig. 4 perspective view Fig. 5 is a horizontal projection of the elements according to Fig. 4 and Fig. 6 a specific embodiment of the insulating element. In the plate bodies according to Figs. The grooves can also be formed as flared sides 2 'according to Fig. 3. The panels 1 of the board are placed against the wall to be insulated from their wall-side surface 4 and are connected to it, e.g. with suitable adhesives. For this reason, the plate body 1 is preferably provided on its surface 4, e.g. with smaller grooves (see Fig. 6), which improve the adhesion with the adhesive 30 (e.g. bitumen). In addition, this wall-side groove has the advantage that the extruded sheet blank can cool, i.e. harden without twisting, i.e. straight.

Furthermore, as shown in Figs. Bonding on both sides in these edge areas is of course possible because the grooved surfaces 5 remain intact.

The filter fiber mat 6, cut to size, may be attached to each plate body 1 according to Fig. 2 and in that form form a preset element, whereby it is possible to provide the elements according to Fig. 5 with non-fibrous edge projections 6 'which overlap each other in the area of their associated edges. that the filter fiber mat 6 also covers the joints.
