Definitions

  • the invention relates to a protective material for bitumen paints or the like, which consists of a thin and essentially stiff plastic film, in which elongated bulges are formed, arranged periodically and in particular produced by deep-drawing.
  • basement outer walls are first protected against moisture by an insulating plaster applied to the masonry and then by an insulating coating in the form of a bitumen coating applied to this insulating plaster, before the soil is refilled against them.
  • an insulating plaster applied to the masonry
  • an insulating coating in the form of a bitumen coating applied to this insulating plaster
  • stones and building rubble contained in the soil can get to the bitumen coating and damage it.
  • Particularly critical conditions arise when the soil to be filled contains large stones or even boulders, or, as is often the case, consists mainly of rubble. Then the risk of damage to the protective coating can practically not be avoided, but if the protective coating is damaged, moisture or water can penetrate the masonry, especially the insulating plaster. So the cellar is practically constantly damp.
  • DE-A-2 545 762 discloses a flexible hollow body made of at least two plastic films, each of which is provided with a multiplicity of nub-like or rib-like features which keep the films at a distance and serve to form a cavity between the films .
  • at least one film has further features which have a simple valley-shaped or an arbitrarily shaped, wavy cross section and which extend linearly over the film. Only if all the additional features run in one direction, the two foils form a hollow body which is only flexible in one direction and is rigid in the direction perpendicular thereto. Otherwise, the hollow body can be bent in all directions and rolled up if necessary. A hollow body that is rigid in all directions is not achieved.
  • an insulating element made of a plastic film which is provided with rows of primary press-in depressions designed as spacers. Due to the distance between the pressings, this insulating element is not stiff in any direction.
  • secondary pressings are provided here, which are designed as conical parts and which, when a plurality of insulating elements are connected to one another, create a good adhesive connection in the edge regions of the overlapping elements by self-locking. There is no push-button-like connection here, which requires an undercut.
  • bitumen corrugated sheets which are made from corrugated, bitumen-impregnated press cardboard.
  • the known protective materials made of corrugated rigid PVC film and manufactured by the applicant have a similar shape. This film is about 0.5 mm thick and also has stability in one direction due to its corrugation.
  • Such films are described, for example, in the in-house announcement by Klöckner-Werke AG "Pütt und Kirte", issue 3, / 77.
  • the aforementioned Norwegian patent specification 111 836 also describes such a corrugated sheet, in which the bulges which run parallel to the waves are additionally provided in the region of the ridge lines of the waves.
  • knobbed film is known from German utility model 7 228 779, which has knobs arranged in a square grid with a round, triangular or square basic shape.
  • the distance between the grid lines of the square grid is significantly larger than the length dimension or the diameter of the knobs. Because of this geometrical arrangement and configuration of the knobs, the knob film can be easily bent, in contrast to the protective material of the type mentioned at the outset, it is not stiff in any direction. This leads to a further difficulty in practical use.
  • the object of the invention is to provide, based on the known protective material of the type mentioned, a protective material which avoids the disadvantages of the known protective material and has better properties than the known one in storage, when the protective material is attached to an outer cellar wall and finally when backfilling a construction pit Protective material shows.
  • This object is achieved in that a first part of these elongated protrusions is arranged in one direction and the other, second part of the protrusions in a direction running transversely thereto, and that the successive protrusions, which belong to part of the protrusions, are each arranged by one transverse bulge from the other part of the bulges are separated, and vice versa.
  • the elongated bulges like the corrugated corrugated shafts, cause stiffening. Since the first part of the bulges runs transversely to the second part, the stiffening effect of the two parts also runs in two transverse directions.
  • the protective material according to the invention is therefore stiff in two directions at right angles to one another in its plane. It can therefore no longer be rolled up like the well-known corrugated sheets (bitumen corrugated sheets or corrugated sheets made of hard PVC) or the well-known dimpled sheet, rather it is offered in large-sized sheets that can be stacked on top of one another to save space and comfortably. A much denser packing is achieved than when rolling up, so that the storage of the protective material according to the invention causes less effort than is the case with the rolled-up products according to the prior art.
  • the large-format panels can be placed very cheaply against an insulating coating; very few fastening points are required because the panels do not roll back, as is the case with the known, windable products, but rather that have a flat shape, which they must also have during their later use. Due to the stiffness of the form, the risk that the protective material according to the invention, due to the pressure of earth material filled from below, will be released from the insulating coating at the top is low and can be excluded in practice.
  • the hard PVC sheets according to the invention are usually laid in such a way that adjacent sheets overlap to a certain extent.
  • push-button-like formations are arranged at least in these overlapping areas, which protrude outwards in the direction of the bulges. They can be arranged on the bulges or next to the bulges and in particular can be part of the bulges. Expediently, they do not protrude beyond the total height of the protective material according to the invention.
  • the design of the push button-like formations is arbitrary per se, the only important thing is that these push button-like formations are arranged periodically in such a way that regardless of a shift of two adjacent protective plates in the two directions of the board plane and independent of a 90 ° or 180 ° rotation of one Panel around an axis perpendicular to the protective panel with respect to the other panels an engagement of the formations is possible.
  • the formations can protrude, for example, in the middle of the non-bulging areas next to the bulges and in the direction of these bulges.
  • at least a portion of the ridge-like tips of the projections be formed as moldings. For this purpose, grooves are pressed in below these tips and approximately halfway up the roof-like bevels, which result in an undercut, so that the tip areas of the bulges get a push-button-like profile.
  • all of the formations have such grooves which form an undercut.
  • the size of this undercut is matched to the material properties and in particular to the material thickness of the protective panel in such a way that the engagement of overlapping formations only occurs above a slight pressure corresponding to a punch.
  • This board can be snapped into place with another, second board at any point and at any 90 ° rotation.
  • Only upper protective panels are attached to a high basement outer wall and clipped onto these lower protective panels. These lower protective panels are not connected to the outer wall itself.
  • the undercut has proven to be very advantageous when the protective material according to the invention is fastened to outer walls by means of an adhesive plaster, in particular plaster of plasters.
  • the protective material according to the invention has a high surface rigidity, which is very advantageous when laying on flat surfaces.
  • the same property leads to difficulties in house corners.
  • it is proposed either to provide L-shaped pieces which are placed on the corners of the house, or the protective material, if it has a lower material thickness, to bend these corners and along a line of protrusions.
  • elongated and roof-like protrusions 21, 22 are pressed out of a lower, flat surface 20 of a hard PVC plastic film in the deep-drawing process.
  • Their cross section is essentially V-shaped, as shown in FIG. 2. Measured at the level of surface 20, their length corresponds to about twice their width and about a quarter of their clear height.
  • the bulges 21, 22 are shaped by square material, the edges of which are rounded off accordingly.
  • the (horizontal) bulges 21, which form the first part of the bulges, are thereby at right angles to the (vertical) bulges 22, which form the second part of the bulges form.
  • a network line for example the straight line 23 running along the section line 11-11 shown in FIG. 1, it can be seen that the bulges 21 (like the bulges 22) are arranged one behind the other and each by a transverse bulge 22 onto which they hit in the middle, are separated from each other.
  • the distance between two bulges 21 (and also 22) on a straight line 23 thus corresponds to the width of a bulge 21 or 22 in the exemplary embodiments according to FIGS. 1 to 4.
  • the distance between two successive ones is Bulges 21 or 22 four to five times the width of the bulge.
  • the bulges 21 and 22 of adjacent straight lines 23 are offset from one another by approximately three quarters of the total length of a bulge 21, 22. This increases the rigidity in the corresponding direction.
  • the rigidity is further increased by spacers 24, which are located in the transition area between the gable side 25 of a recess, e.g. 21, and the longitudinal center of the slope of the adjacent protrusions, e.g. 22 are arranged.
  • Four adjacent bulges 21, 22 each frame a square area 26, which is located essentially in the plane of the lower surface 20 (FIGS. 1 to 4).
  • protrusions 29 are provided in each square region 26 in the opposite direction to the bulges 21, 22.
  • the protective material according to the invention (protective plate A) is placed against an insulating coating I with the surface at the top in the figures, in which the ridges of the bulges 21, 22 are located.
  • the lower surface 20 then faces outwards.
  • Earth material E can be filled directly onto them, but it is more advantageous to clip a drainage plate B onto this lower surface 20, which will be discussed later.
  • This arrangement is shown in Figs. 9 and 10.
  • a very large volume of air which is larger than other protective materials known from the prior art, is enclosed between the protective material and the basement outer wall. This leads to very good thermal insulation.
  • drainage channels remain free between the protective plate A and the basement outer wall, which, however, do not run vertically, as in the case of the bitumen corrugated plates, but are approximately zigzag-shaped. This has the advantage that stones do not fall through to the bottom, but overall an excellent drainage of penetrated water is achieved.
  • FIGS. 3 and 4 the formation of push button-like formations 27 is shown.
  • the exemplary embodiment shown in FIGS. 1 and 2 which otherwise corresponds to the second exemplary embodiment according to FIGS. 3 and 4, which is now to be discussed, is approximately in the middle of the roof-like slopes of each bulge 21, 22 and on both sides in the direction of groove in each curvature 21, 22 so that an undercut is formed which has the dimension x (see FIG. 4).
  • the entire ridge-like tip of each individual bulge 21, 22 becomes a push-button-like shape 27. This can be pressed into another shape 27 above or below it.
  • the undercut x is matched to the elasticity and the material thickness of the protective panel in such a way that the push button-like shape 27 remains sufficient and elastic in order to be able to be pressed into another shape 27. It is not necessary for the formations 27, as shown in FIGS. 3 and 4, to extend over the entire length of the bulges 21, 22. However, they must be arranged in such a way that they always enable snap-in regardless of the relative position of two overlapping protective panels.
  • the exemplary embodiment according to FIGS. 5 and 6 essentially corresponds to the exemplary embodiment according to FIGS. 3 and 4.
  • the bulges 21, 22 are made narrower, their length corresponds approximately to six times their width.
  • the distance between bulges 21, 22 lying on the same straight line is greater than the width of a bulge, here it is approximately one third of the length of a bulge 21, 22.
  • no spacers 24 are provided.
  • the characteristics 29 have already been described above.
  • grooves 28 are provided in the middle of each bulge 21, 22 and thus on the straight line 23, which serve as a predetermined kink for the corner bend.
  • the plane 20 is practically no longer formed in the exemplary embodiment according to FIGS. 5 and 6, the relatively large, flat parting surfaces 30 can be used however, as a very wide, large spacer.
  • a drainage plate B is shown. It is essentially flat and has bulges 21 'and 22' which are arranged at a great distance from one another and which are identical to the bulges 21 and 22.
  • a drainage plate B can thus be clipped onto the back of a protective plate A, as shown in FIG. 10.
  • the drainage plate has drainage openings 31 arranged in a periodic fashion.
  • the protective material according to the invention is produced in relatively large-format plates, the height of these plates corresponds to the filling heights that usually occur and is approximately 1.20; 1.68 and 2.2 m.
  • Two plate formats e.g. 2.2 x 1.20 and 1.68 x 1.20
  • the PVC material is colored black.
  • the material thickness is 0.5 mm to 0.8 mm.
