Description
~ ~6~7~3 The present invention relates to a protective shee-t, in particular for a foundation wall or a floor on the ground, comprising a substantially planar sheet or suitable, relative-ly stiff material, e.g. plastics, where one side of the sheet has a large number of spaced protrusions constituted by knobs made by forming, whereby the o-ther side of -the sheet thereby obtains a corresponding number of recesses provided by said forming. Such a sheet is known, for example, from DE-A-26406~5 and DE-A-3006820.
The known so-called foundation wall sheets are presently used extensively as a covering of the foundation wall before fill masses are piaced thereat. Where access to draining fill masses is poor, it is frequently an expressed wish to ensure that the water pressure against the foundation wall becomes -the least possible. Such additional drainage is not always that easy to provide by means of the known foundation wall sheets having knobs. Further, it may in certain cases be desirable to provide the foundation wall shee-t with knobs which do not quite so easily yield due to external forces from e.g. the fill mass. Recently it has also been common to use these foundation wall sheets as a diffusion bar for a floor on the ground. With the prior art solutions~ it is, however necessary to provide spacing means to space the floor from the moisture bar, in order to provide sufEicien-t ventila-tion or drainage under the floor. This is particularly important in the cases where a floor made e.g. from chip boards is used.
Thlls, the present invention has as an object to provide a protective sheet providing a solution to the indicated draw-backs. The present invention provides a protective sheet, in particular for a foundation wall or a floor on -the yround, comprising a substantially planar sheet of suitable, relatively stiff plastic material, one side of the sheet having a large number of spaced protrusions constituted by knobs provided by forming, the o~her side of the sheet thereby obtaining a ,~, ~6~
corresponding number of :recesses provided by the forming, charac-terized in -that the knobs have a reversely directed centrally disposed craler-like portion of truncated conical form, the widest end of which is in-tegral with the upper por-tion of the knob and -the narrowest end of which is substanti-ally flush with the other side of -the sheet.
In a preferred embodiment open channels are provided for drainage of fil-trated water. A corresponding rib is forrrled on one side of the sheet with a height less -than the height of the knobs, characterized in that each of the open channels extends between and has respective ends opening into the re-cesses of adjacent knobs.
Further features of the invention will appear from the subsequen-t description with reference to the attached drawings.

In Fiy.l there is shown a protective shee-t, e.g. of rela-t:ively stiff plastics which may possibly before use be present in a rolled-up form. As indicated in Fig.2, knobs 2 protrude from the one side lA of the sheet, said knobs having a cen-tral-ly arranged crater-like portion 3 and where the bottom of ~he crater 3A is flush with the other side lB of the sheet.
Between the recesses 2A provided by the forming of the knobs
The known so-called foundation wall sheets are presently used extensively as a covering of the foundation wall before fill masses are piaced thereat. Where access to draining fill masses is poor, it is frequently an expressed wish to ensure that the water pressure against the foundation wall becomes -the least possible. Such additional drainage is not always that easy to provide by means of the known foundation wall sheets having knobs. Further, it may in certain cases be desirable to provide the foundation wall shee-t with knobs which do not quite so easily yield due to external forces from e.g. the fill mass. Recently it has also been common to use these foundation wall sheets as a diffusion bar for a floor on the ground. With the prior art solutions~ it is, however necessary to provide spacing means to space the floor from the moisture bar, in order to provide sufEicien-t ventila-tion or drainage under the floor. This is particularly important in the cases where a floor made e.g. from chip boards is used.
Thlls, the present invention has as an object to provide a protective sheet providing a solution to the indicated draw-backs. The present invention provides a protective sheet, in particular for a foundation wall or a floor on -the yround, comprising a substantially planar sheet of suitable, relatively stiff plastic material, one side of the sheet having a large number of spaced protrusions constituted by knobs provided by forming, the o~her side of the sheet thereby obtaining a ,~, ~6~

In a preferred embodiment open channels are provided for drainage of fil-trated water. A corresponding rib is forrrled on one side of the sheet with a height less -than the height of the knobs, characterized in that each of the open channels extends between and has respective ends opening into the re-cesses of adjacent knobs.

Fig.3 is the cross-section of Fig.2 related -to a filtrat-ing canvas.
Fig.4 illustrates the use o. the protective sheet in a manner known per se.
Fig.5 illustrates the use of the protective sheet in con-nection with a filtrating canvas.
Fig.6 illustrates the use of -the protective shee-t as a moist bar for a floor on the ground.
In Fiy.l there is shown a protective shee-t, e.g. of rela-t:ively stiff plastics which may possibly before use be present in a rolled-up form. As indicated in Fig.2, knobs 2 protrude from the one side lA of the sheet, said knobs having a cen-tral-ly arranged crater-like portion 3 and where the bottom of ~he crater 3A is flush with the other side lB of the sheet.
Between the recesses 2A provided by the forming of the knobs
2, there is on the other side 1~ of the sheet provided an open channel 9. On said one side lA of the sheet there is thus a ~6~7~
corresponding rib or ridge. The sald channels 4 will, as regards a vertically disposed protective sheet, extend between adjacent recesses 2A being arranged vertically above each other.
llowever, there is nothing agairlst the knobs being arrarlged i,n a different manner than that il,lustrated in Fig. 1.
Thus, the knobs of one row of knobs could be shifted rela-tive to the knobs in -the adjacent rows of knobs.
In -the cases where the protective sheet is to be arranged in an environment having masses providing poor drai,nage, it may be an advantage to arrange a ~iltratin~
canvas 5 on the said other side lB of the sheet.
In Fig. 4 there is shown a first mode of use for the protective sheet 1, where it is arranged in a tradition-al manner with the knobs facing a foundation wall 7. Fill mass 6, e.g. broken stone or other mass having good drainage property is placed against the other side of the sheet.
This draining mass may cause a substantial pressure against the sheet, wherefore the crater-like portion of the knob will effect a stiffening of the knob itself and ensure -the necessary distance between the protective sheet and the foundation wall. The channel 4 will in addition effect further drainage along the other side lB of the sheet, wherefore the water pressure against the sheet is reduced.
In Fig. 5, the mass 8 is in the form of mass having poor drainage capability, e.g. clay or fill mass containing earth. In this case it is desirable to arrange the fil-tr-ation canvas externally of the other side of the sheet, whereby water being filtrated through the canvas escapes via the channels 4.
The filtrating canvas 5 prevents the channels ~
from being blocked by the mass 8. In this connection the crater-like portion 3 of the knob 2 will effect further support of the canvas 5 and prevent it from being pressed into the recess 2A.
In Fig. 6 there is shown a protective sheet 1 intended as moist bar for a floor 9, e.g. a floor made from plates of wood chippings. Sheet 1 is arranged on a cast layer 10 on the ground (not shown). The channels 4 _4~ 7~
will in this case contribute to a certain ventilation between the floor plate 9 and the protecti~e sheet 1.
Further, the crater-like portion 3 of -the knob 2 upon heavy point loads on the floor 9 contribute to the knob better withstanding such deforming forces.
