Definitions

  • the invention relates to an insulating panel for thermal insulation and for water drainage of subterranean, basement, building or construction walls.
  • the panel has a plurality of drainage channels which are open on one surface of the panel and which extend from a first panel edge to a second panel edge located oppositely thereto and are open at both panel edges.
  • Such insulating panels are used for thermal insulation on the outer side of the wall and for water drainage of such walls. During construction the panels are placed against the wall to be protected prior to the backfilling of earth. Apart from their temperature insulating properties these panels provide for the drainage of water, specifically rain water which can flow along the drainage channels downwardly into the ground or into water collection pipes.
  • Such panels each have a plurality of vertically extending grooves, such as disclosed, e.g., in German published patent application No. DE-31 13 807.
  • the panels have a common drawback, however, in that the vertically extending drainage grooves of the individual panels which are located vertically on top of each other may not be properly aligned during the build-up of such outer cladding of a wall.
  • the vertically stacked panels may shift laterally relative to each other or may get partly clogged such that various blockages of the draining channels will occur.
  • An object of the invention is to provide an insulating panel of the kind metioned above, which does not feature the aforementioned drawbacks and which provides for effective drainage at all lateral relative positions of the individual panels forming the outer covering for subterranean walls.
  • the insulating panel is characterized in that a connecting channel each is located in the side surfaces of the panel extending along the first and in the second panel edge and communicating with every drainage channel and extending perpendicularly thereto.
  • the insulating panel is an integral structural member and has the shape of two plate bodies located on top of each other and offset in diagonal direction relative to each other, such that every side surface of the panel ahs a step-like extent whereby adjacent panels overlap partly and guide each other.
  • the panel surface which is provided with the drainage channels can be covered by a web-like material such that the drainage channels are covered and protected from clogging-up by soil, gravel or the like entering the channels.
  • the insulation panel of which an upper end portion is shown in Figure 1 can be fabricated of any kind of suitable material, such as an extruded plastics material, a foamed plastics material or a mortar-bound material.
  • the insulating plate is made of an extruded polystyrene foam.
  • One main surface of the panel is provided with vertically extending parallel drainage channels 1, which extend along the entire vertical length of the panel.
  • a connecting channel 4 is formed in the top side surface 2 of the panel.
  • a similar connecting channel 4 is provided at the bottom side surface 3, -such as is shown, for example, in Figures 2 and 3.
  • the connecting channel 4 extends in a direction perpendicular to the drainage channels 1 and is offset relative to the drainage channels 1 in the direction of the panel thickness.
  • the drainage channels 1 partly intersect the connecting channel 4 such that the outer side wall of the connecting channel 4 has a plurality of openings 5, each of which forms a passageway communicating the connecting channel 4 with the drainage channels 1.
  • FIG 2 there are shown two insulating panels stacked vertically on top of each other.
  • the panels are laterally offset relative to each other such that their individual drainage channels 1 are not aligned with each other. This no longer poses a problem regarding the drainage of water, because the water draining down the drainage channels 1 of the upper panel enters into a connecting channel 4, flows horizontally along this connecting channel 4 until reaching the next drainage channel 1 of the lower panel through which it can flow freely further down.
  • Such lateral off-set installation of adjoining insulating panels may also be made on purpose such that during back-filling of the earth, for example, only the individual drainage channels 1 of the uppermost panel may be filled with debris (e.g., soil, gravel, and the like) because the path for such debris to the lower panel is securely blocked by such off-set arrangement.
  • debris e.g., soil, gravel, and the like
  • FIG. 3 there is shown a preferred cross-sectional shape of a connecting channel 4, which in this case has a rectangular cross-section.
  • the bottom 6 of the connecting channel 4 may extend obliquely towards the drainage channels, as illustrated in Figure 4.
  • a large variety of cross-sectional shapes of the connecting channels 4 is possible, one further semi-circular shape is illustrated in Figure 5.
  • the insulating panel of the embodiment shown is an integral body having stepped side walls. It basically has the shape of two panel bodies 7 and 8 located on top of each other such that they are offset in a lateral direction relative to each other. This will not only result in a mutual guiding of adjacent panels, but also prevent foreign bodies, for instance small-sized bodies of backfill, to enter between the two panels.
  • the panel surface in which the drainage channels 1 are located is optionally covered by a web-like material 11, such that the drainage channels 1 are protected from the incursion of foreign materials into the channels which may block the flow of water along the channels.
  • This covering web 11 may be of any kind of material as long as it is water permeable. According to Figures 6 and 7 this covering web or porous sheet projects over two adjacent sides 7, 9 of the panel, such that the covering webs 11 of two adjoining panels overlap each other.
  • This advantage of this embodiment is that an imperfect alignment of neighboring or adjacent, respectively, panels cannot have any detrimental effect regarding the entry of foreign particles.
  • This overlapping design on the one hand of the edges and on the other hand of the covering webs can also allow for an at least temporary locking of adjacent panels during installation by any kind of a sharp pointed object.
