Description

The invention relates to a shower tray element, which consists of a cuttable material, preferably a foam, in particular particle foam, at least in a designated discharge region and has on the underside a preferably substantially planar lower surface.

The invention further relates to a method for installing a drainage channel in a drainable area, at least in a designated drainage area, of a cuttable material, preferably a foam, in particular particle foam, consisting of a bottom floor having an at least partially substantially planar lower surface.

The invention also relates to a mounting kit for such a shower floor element. In addition, such a shower tray element installed with an inserted gutter.

The invention further relates to a shower floor element, in particular for floor-level and / or floor-flush installation, wherein the shower floor element has a top with a slope and from one side, bottom and / or above formed and possibly having a floor or ceiling cavities.

The invention further relates to a method for installing a shower floor element with from below and / or above outgoing, possibly a floor or a ceiling having cavity areas.

Such shower floor elements and gutters for installation with a shower floor element have already become known in many ways. It is for example on the DE 10 2008 059 514 A1 , the EP 1 782 721 A2 , the EP 2 184 414 A1 , the EP 1801300 A2 , the DE 10 2008 046 671 A1 and the EP 1 287 213 B1 directed.

The gutters of different manufacturers usually have different dimensions. In addition, a gutter of a special type of manufacturer can often be obtained in different sizes, that is, in particular different lengths.

In order to achieve a convenient installation option with respect to a shower floor element, it is from the EP 205 007 A2 known to use in such a shower floor element a separate, designed as an adapter part, or the shower floor element immediately form a total as an adapter. In such an adapter, at least the different gutter sizes of a series of a manufacturer can be installed without changes being necessary. It is also known to provide breakouts in an adapter area.

Such an adapter but constructively meets certain limits, if a large variety of gutters to be built. Also looking for an alternative design to consider different forms of gutters.

On this basis, the invention has the object, a shower floor element, optionally with a built-in gutter, specify that is suitable for as many different gutters and / or allows a simple, convenient but also rational installation of a gutter or so is installed with the gutter. In addition, the invention has the object to provide a related method. Furthermore, the invention has the object to provide a suitable installation set for such a shower floor element. Also, the invention has the object to provide a shower floor element which is particularly advantageously installed acoustically sound and a method for advantageous acoustic installation of a shower floor element.

A possible solution to the problem is initially given in a shower tray element, in which a mark in the form of one or more depressions, grooves or lines pretending that can be formed by cutting gutter receiving area.

Procedurally, a possible solution is given by the fact that a mark in the form of one or more depressions, grooves or lines is set in a formable by cutting gutter receiving area and in the predetermined gutter receiving area an insertion opening for a gutter is formed by cutting and the gutter is inserted into the inlet opening.

A possible solution is also a mounting set for a shower floor element, on the one hand preferably has an area with one or more depressions, grooves or lines for specifying a formable by cutting gutter receiving area and on the other hand a template for forming an adapted to a particular gutter opening area.

The subject matter is also a, optionally already installed, shower floor element, wherein the gutter in an at least partially individually cut Opening of the shower tray element is arranged. In this case, a part of the opening can be predetermined prefabricated.

A possible solution to the problem is also given in a shower floor element, in which the cavity areas are formed substantially uniformly distributed over a base surface of the shower floor element.

A possible solution to the problem is also given in a method for installing a shower floor element, in which upwardly open cavity areas are filled with a heavy material such as tile adhesive or screed concrete and then a cover in the form of a film is made, the filling and cover either before finally placing the shower floor element is made at its installation or at the installation of the shower floor element.

Further features of the invention are described below, also in the figure description and the drawing, often in their preferred assignment to the already discussed above concept or illustrated, but they can also be assigned to only one or more individual features described herein or are represented graphically, or independently or in a different overall concept, be of importance.

Thus, with regard to the shower tray element, it is preferred that an elongate, substantially rectangular in plan view recess is provided with a formed on a part of the floor plan cutting output area, for example in the form of a vertically continuous opening. It is also preferred that a lowering at least partially forming, is formed with a clearance leaving a distance to the lower surface of the shower floor element extending cutting blanket.

With regard to the installation set, it is also preferred that the shower floor element has a cuttable area which forms the recess as described.

With regard to the formation of the lowering, a way has been taken to design the lowering in a shower tray element (only) so that initially none of the known drainage channels can be used directly without further measures being necessary. For insertion is rather necessary, for example, with a saw or a knife, a cutting out of a certain area, namely preferably of such a range of adapted to a relative to an outer support flange lowered central region of a gutter to make. Preferably, therefore, the cutting output region is formed so that it is not adapted to any concrete gutter - or their central region. Rather, it is more preferably formed so that a correspondingly continuous opening does not fit to any central region of a gutter in question. Eligible drainage channels are commercially available drainage channels of such gutter manufacturers, which are intended for installation generally in shower tray elements.

Due to the aforementioned pre-education of the shower floor element can be rationally created an individual recess in the shower floor element for a particular gutter rationally. Characterized in that an output opening or mark is provided, finds a cutting or sawing element, which is used for this, also a favorable cutting start. The cutting blanket forming at least partially the lowering can be comparatively be kept thin. It is easy to cut through. Because it runs with clearance to a lower surface of the shower floor element, in such a region of the ceiling can also be cut when the shower floor element rests with the bottom on the floor.

A built-in shower tray element provided with a gutter according to the embodiments described here is accordingly characterized in that the gutter as a whole, as far as no flange portions are provided, or in the case of Flanschbereichen the central region of the gutter, in a completely or at least partially individually cut opening of the shower floor element rests.

The gutter or said central area preferably lies in a cutting ceiling which forms the depression and preferably extends at least partially into a clearance leaving the free space to the lower surface of the shower floor element.

Alternatively, it can also be provided that in any case the cutting output region is adapted to a specific gutter, preferably its central region. The lowering can then correspond to the width of the particular gutter, optionally in its flange area. Preferably, however, the width is larger. The same applies to the length of the reduction.

A shower floor element described here is also preferably designed for ground-level, floor-level installation, ie barrier-free, suitable for wheelchair use, for example.

In the case of a cutting blanket, it is also preferred, if it has a region which extends at a distance from the lower surface of the shower tray element, to form the cutting blanket with a thickness of 2 to 20 mm in this region. More preferred are about 6 to 12 mm thickness. The free distance to the lower surface can be 10 to 70 mm. The said thickness of the cutting blanket is also dependent on the density, in the case that a foam is used as a material. At high densities can be favorably realize a relatively thin cutting blanket, which nevertheless has the required stability (in the region in which the insertion is not formed).

The width and length of the depression is preferably equal to or greater than the largest candidate width or length of a gutter to be used selected accordingly. In this case, in particular, the length can also be chosen significantly larger than a candidate longest gutter.

A vertical dimension of the central region, that is to say the extent which the downwards extension of the middle region - if a flange part is provided - or the drainage channel itself, if no flange is provided, is designated as the gutter with respect to the surrounding flange region or the upper peripheral edge of the gutter in a first embodiment, less than the thickness of the cutting blanket. The central region can thus be completely in register with a thickness of the cutting blanket in it. Alternatively, the vertical dimension is also larger than said thickness of the cutting blanket (or as the gutter itself, in terms of its vertical depth, if no flange is provided), so that in this case it laterally follows the surrounding area of the cutting blanket in said central area surmounted below.

An underside of the middle region of the drainage channel can be completely exposed in the installed state on the one hand. On the other hand, sitting or sitting on a heavy material, which may be provided in particular with regard to a sound-favorable design of the shower tray element, can also be provided. The heavy material possibly used here is further explained below.

On the underside of the gutter, one or more feet, connected to the gutter itself, may be formed in a manner known per se, and such a base may be freely suspended in the installed state. On the one hand, the load transfer with respect to the gutter can only be done via the shower floor element itself. So on a lower surface of the shower floor element. On the other hand, but also on a foot or the said heavy material or other sub-base plate, which extends below the gutter.

With regard to an optionally provided template, it is preferred that it be formed while leaving the cutting output area corresponding to a floor plan of the middle area of the desired gutter. In any case, this is particularly preferred when the template is a (paper) sheet-like template. In particular, when the template is a fixed part may also be preferred that the template has a board area, which also engages in the cutting output area for support. It may also be provided in this regard that the user cuts out such a template only from a sheet-like sheet, which has just different outlines for different gutters. The template may serve to apply along its edge a marking line to the corresponding region of the depression or to cut it out immediately along its edge.

A surface of the shower tray element in a region in which the drainage channel is to be used, or more specifically a surface of the described depression, can also be structured by ribs. Preferably, such ribs extend in a parallel orientation to a peripheral edge of the shower tray element, in the direction of the longitudinal direction of the gutter to be installed. In the case of a lowering, they preferably extend in the longitudinal direction of the further preferably provided with a greater length than width reduction. In particular, first and second ribs may be provided, which preferably differ with respect to their length. Accordingly, they preferably have the same width. These ribs can have the effect of performing straight cuts and / or angled separating edges in the region of this surface area of the shower floor element or, in particular, of the sinking. Since the possibly to be used gutters differ in width but also possibly the length, but on the other hand, a middle region of the gutters, or if no flange is provided, the gutter as such, even if with a different width, a designated range of reduction or the corresponding surface area of the shower floor element is always fill, the first ribs are those greater length, which also preferably in the central region of the reduction or the intended area of the shower floor element, based on a longitudinal extension of the reduction or a longitudinal extent of the markings formed. The second ribs, which are preferably ribs of shorter length, are correspondingly preferably associated with the end regions of the sink, if provided. formed or the end of the marking area.

Furthermore, a third rib structure may also be formed in a central region in relation to the width of the depression or of the region of the marking, which is characterized by an even greater width, preferably twice or more the width of the first or second ribs. This third rib structure may, preferably in the longitudinal direction of this rib structure extending, depressions have, which are not formed, at least in a part of the ribs, in the sense of a dash-dotted line not continuous.

The said third rib structure can also be provided as a whole (only or in addition).

The width of a rib, in any case a first or second rib, preferably corresponds to one twentieth or more of the width of the reduction or the width of the marking area, up to, for example, in particular based on the third embodiment of the rib, a third or half the width of the Lowering or the marking area.

Another object of the invention, which is also independent of the above-described embodiments, but also combined with one or more features of the preceding embodiments meaning, is a shower tray element, which preferably consists of a foam, in particular particle foam, as described above, at which bottom element of the shower tray is formed on the underside preferably a substantially flat lower surface and extend from this lower surface cavities in the interior of the shower tray element.

In order to specify a particularly sound-technical shower floor element, it is provided in this regard that one or more of the cavities are filled with a respect to the material of the shower floor element specific heavier material.

The cavities, relative to the bottom surface of the shower tray element, with respect to their mouth area in the bottom of the shower tray element, a proportion of the bottom surface of the shower floor element from 20 percent or more, up to 70 or 80 percent, or in some cases even more. The cavities are not continuous as indicated by the term. But it can also be provided through openings that can complement each other for non-through openings, for example.

With regard to the filling material of the cavities is particularly preferred that this has a 10 to 100 times or higher specific gravity than corresponds to the material of the shower floor element as such. For example, the foam material may have a specific gravity of 50 kg / m ³ , as will be described in more detail below, while the filler material, which may be, for example, a screed, may have a specific weight of 1 to 3 kg / l. Accordingly, there is a ratio of, for example, 1:20 to 1: 1000 between the base material of the shower tray element and the filler material in terms of specific gravity.

The material used for the shower tray element (also referred to above as the base material), in particular a foam, preferably a particle foam, may have a density in the range of 25 to 110 kg / m ³ , preferably a range of 25 to 90 kg / m ³ . It is also possible to use a biopolymer, for example based on cellulose, as the material.

In particular, in this regard, a shower tray element is preferred which already has a gradient surface on the top side and has cavities in the most even distribution possible. These may be formed starting from a lower surface and / or a surface of the shower base element and preferably extending vertically. In particular, they can be passage openings. But they can also have a, preferably comparatively thin, ceiling or a thin bottom. These cavities can be formed in the same way in the area in which the drain or a gutter is to be used. They can also serve as cutting exit openings for cutting out the opening ultimately intended for the particular gutter or special drainage.

In this case, first, the opening for the drain or the gutter can be cut out, the drain or the gutter can then be used and finally in the areas in which laterally with respect to the cut opening results in an expansion, characterized in that the opening in one extent spreading cavity passes, a filling made with heavy material in the sense described.

On the other hand, such a configuration of a shower tray element is also suitable for the formation of conventional receiving recesses for a drain or a drainage channel. In such a case, then the corresponding areas are omitted from the said cavities.

In particular, it is preferred that a vertically projected area ratio, based on a flat base area, between the cavities and the non-hollowed areas of the shower tray element is in the range of 3: 7 to 7: 3.

In terms of production and thus procedurally, it is possible to proceed in such a way that in the described manner, if in this case a cutout of a receptacle for the drainage or the drainage channel is to be provided, this cut-out is made, then the drain or the drainage channel is inserted and subsequently then the cavities are filled with the heavy material. As far as the cavities are also open at the top, it is then further preferred that the top of the shower tray element undergoes a cover in the form of, for example, a foil cover.

With regard to the disclosure, the ranges and ranges of values given above and below also include all intermediate values, in particular in 1/10 steps of the respective dimension, if appropriate also without dimensions, for example 1/10 kg / m ³ , 1/10 mm, 0 , 4 of the width, etc., on the one hand to delimit the mentioned range limits from below and / or above, alternatively or additionally, but also with regard to the disclosure of one or more singular values from a respectively specified range.

Shown and described is a, in the embodiment, in two parts trained, shower floor element 1. The shower floor element 1 can also be integrally formed in one piece. In a drain region provided, a depression 3 is formed which, as can be seen, is preferably elongated and rectangular. In two-part training this reduction 3 is formed in a first part 2. Except for a narrow edge strip 22 which extends on the upper side with a surface O of the shower tray element 1, the depression 3 preferably extends over an entire width B of the shower tray element 1. The edge strip 22 preferably has a width c which is one third or less towards, for example, one twentieth of the width b of the depression 3 corresponds.

With regard to elongated in this context, in particular a ratio is addressed in which a length twice or more equal to the width, up to preferably ten times.

In the depression 3, a vertically continuous opening 4 is formed, which in the present context, as will be explained further, can serve as a cutting output region.

A width b of the depression preferably corresponds to 100 to 300 mm. A depth t, the Absenkmaß the lowering 3, preferably corresponds to 3 to 10 mm, more preferably 5 mm.

In the second part 5, preferably associated with the opening 4, a window region 6 is formed. The window area 6 also represents a vertically through opening. Because the window area 6 is assigned to the opening 4, it is immediately adjacent to it. Relative to an extension direction of the elongated depression 3, the opening 4 and the window area 6 are arranged side by side transversely to this direction of extent. More preferably, in relation to the mentioned direction of extension, the window region 6 is smaller than the opening 4. However, in a direction perpendicular to the direction of extension, the window region 6 is preferably made larger than the opening 4.

It can be provided that the opening 4 and the window area 6 do not merge into one another. However, the window region 6 can furthermore preferably be provided opening into an edge surface 7 of the second part 5. It may also be closed by a strip section forming the edge surface 7 in this region. The edge surface 7 is in the installed state, such as out FIG. 5 The mating edge surface 8 closes in the first-mentioned embodiment, as it were, the window region 6. Preferably, the opening 4 is also completely formed within the depression 3. Further preferably also such that still within the Lowering 3 the remaining area of the opening 4 forming remaining sections result.

The window region 6 is important for receiving a discharge part, for example an elongated discharge part with an odor trap, as is known from US Pat WO 2010/026088 A1 is known and in FIG. 5 After installation of the discharge part, the window region is preferably covered on the upper side with a thin closure part, more preferably a sheet metal part. For this purpose, frame-like surrounding, preferably two- or three-sided, but possibly also four-sided surrounding, to the window area 6 in the shower tray element a frame lowering 9 is preferably provided. For example, this results in a possibility of revision.

As in further FIG. 1 indicated, starting from the opening 4 by means of a cutting or sawing member 10, an opening surface 11 are formed, which to an individual gutter 12, see FIG. 5 , with respect to a central region 13 of the gutter 12, is adjusted. The cutting or sawing is made with respect to a cutting blanket 14, which is partially exposed at a distance a to a footprint 15 of the shower tray element 1, and partially with the exception of the amount of reduction 3 over the entire height h of the shower tray element 1 (in this area) , Preferably, the opening surface 11 is formed only within the recess 3.

In particular, in the free-stretched areas of the cutting blanket can be easily and quickly form the opening surface 11. The rib-like thickening regions 16 of the cutting blanket 14 remain as far as the opening surface 11 extends into this, at least laterally and thus contribute to the stability of the installed shower floor element advantageous.

In particular FIG. 3 can be seen, are in transverse alignment to the extension direction of the reduction 3, the underside of the shower tray element a plurality of such thickening portions 16 formed side by side. They preferably span the entire width of the depression 3. More preferably, they then go over integrally into the respective adjoining region of the shower floor element. They also preferably form part of the planar lower surface U (cf. FIG. 2 ). The lower end faces of the thickening regions 16 are aligned in the lower surface U over. They further define mutually separate hollow areas 17, which are each closed on the upper side by the cutting blanket in their configuration at a distance a to the footprint 15.

In the region of the opening 4, a larger cavity area 17 is formed on the underside to the free peripheral edge 18 of the first part 2, which is suitable for free cutting and the remaining web 19, a drain line to extend in this direction to record. A cavity 24 or 25 adjoining the cavity 17 or the opposite cavity 23 in the extension direction of the depression 3 can still be reached directly from the opening 4. The next, the cavity 23 and 24 final thickening region 16 is at the same time in this area the boundary of the opening 4. In addition, a cavity 24 or 25 is preferably formed smaller in width. It further preferably corresponds to approximately half the width of the cavity regions 17. The cavities 17 and 23 are each only partially closed by a region of the cutting cover 14. Incidentally, they are, as the Cutting blanket 14 here also forms part of the edge of the opening 4, open. The same applies with regard to the cavities 24 and 25, respectively.

In the second part 5, a plurality of such described further cavities 17 are also formed on the underside. In contrast to the previously described cavities 17, these are preferably made more irregular. With a substantially triangular or rectangular base. They serve also to allow the cavities 17 extending in a continuation of the juxtaposition of the opening 4 and the window area 6, the laying of a corresponding drain line. In contrast to the cavities 17, however, they are opened only on the underside, in the remaining connecting webs 16, and the ceiling 20, which closes such a hollow 17 in the second part 5 upwards, preferably remains untouched.

In the gutter 12 a gutter part 26 is further shown used.

Out FIG. 5 It can also be seen that a thickness d of the cutting blanket 14, in its cantilevered region, is chosen to be greater than a lowering dimension s of the central region 13 of the gutter 12. Preferred, although not shown, is an embodiment wherein the thickness d in said cantilevered region is chosen to be smaller than a sinking dimension s of the central region 13 of the gutter 12.

Starting from the central region 13, a flange section 21 of the gutter 12 extends outwardly on both sides. This is located in the depression 3. This still remains up a step area of the reduction, since in the assembly site here still a replenishment with tile adhesive and / or Dichtschlämme is made. This may also be provided below the flange portion 21 in addition or alternatively.

In the embodiment of the FIG. 6 the separation between the first part 2 and the second part 5 is provided so that the window area 6 is preferably completely contained in the first part 2 including its frame lowering 9. This also results in how about FIG. 8 it can be seen that the said cavity regions 17, with the exception of the cavity regions 17 extending in extension of the juxtaposition of the opening 4 and the window region 6 in the second part, are completely formed in the first part 2.

The FIGS. 6 and 7 show an embodiment in which the parts 2 and 5 have approximately the same size.

Related to the FIGS. 9 and 10 an embodiment is shown in which the depression 3 is structured with ribs 27, 28 and 29. As can be seen from the cross-sectional representation FIG. 10 gives the ribs 27, 28, 29 a, preferably for all ribs lying in a same plane, top 30, which is opposite the top O of the surrounding area, which is also preferably planar, is lowered by an amount that already mentioned measure of the depth t corresponds. In contrast, between the ribs 27, 28, 29 left grooves 31 are lowered again. Preferably, the Absenkmaß the grooves 31 1/10 to 3/4 of the Absenkmaßes t.

Specifically, the ribs 27 are to be referred to as first ribs. These are assigned to a mean range, based on the length of the reduction 3. These first ribs 27 extend over a length section 1 of the lowering 3, which corresponds to ¼ to ¾ of the length of the depression 3, preferably ⅓ to ½ the length L of the depression. Between first ribs 27 and second ribs 28, the grooves 31 are provided extending, the width of which preferably corresponds to a width of the first and / or second ribs 28.

Further, second grooves 32 are also provided which extend transversely to the grooves 31, wherein the grooves 31 extend in the longitudinal direction of the depression 3. The grooves 32 preferably have a smaller width than the grooves 31, more preferably a width which corresponds to 2/3 to 1/10 of the width of the grooves 31.

The third ribs 29 have a width that is preferably significantly greater than the width of the first or second ribs 27, 28. A width of the third ribs 29 preferably corresponds to 1.2 - 3 times the width of a first rib 27 or a second rib 28.

In this case, two different embodiments can again be distinguished with respect to the third rib 29. On the one hand that two ribs 29 are arranged side by side, completely separated by a groove 33. In this case, the groove 33 preferably has a width which corresponds to a width of the second groove 32. A second type of the third rib 29 has groove-like recesses, which are not continuous in the longitudinal direction of the third rib 29. As a result, the width of the third rib 29 is compared to the above-described embodiment of the third rib 29 also practically doubled accordingly. This type of training of the third rib 29 with dead-end cuts or island-like cuts, given by grooves 33, allows a favorable separation but also leaving Ausschnittbereichen in this area.

The said structure of the grooves 33, such that they only enter into a rib 27, 28, 29, but do not pass through or are formed like an island therein, can also be realized for one of the first or second ribs 27, 28.

The invention also provides a method for installing a gutter into a shower floor element, in particular a shower floor element with one or more of the features, as explained above. In this case, a shower floor element consisting of a cutable material, which material is preferably a foam, such as in particular particle foam, has an elongated, essentially rectangular ground plan depression and with a cutting output area provided on a part of the ground plan surface is provided, wherein the cutting exit area is given for example in the form of a vertically continuous opening, the opening by cutting preferably a portion of a lowering forming, at least partially leaving a clearance to the lower surface of the shower floor element cutting blanket on a central region an opening groove to be inserted corresponding opening area expanded to form an insertion and then inserted the gutter with its central region in this insertion. In this case, moreover, a template relating to this can be used to form an opening surface adapted to a specific gutter.

In the embodiment of the FIGS. 11 and 12 the gutter 12 is shown with flange portions 21. However, the description also applies to a gutter 12 without such flange portions 21.

It is essential that the gutter 12 rests in the, here upper, shower floor element 1 in an at least predominantly individually cut opening 4. This opening 4 is created in the same width continuously through the shower floor element 1 vertically. Although, as in the embodiment of FIGS. 11 and 12 as well as in the embodiment of the FIG. 5 given, the thickness d of the cutting blanket is greater than the einitzende area s of the gutter 12th

The opening 4 continues in the embodiment on the bottom side in a shim 34, which may be formed as the same foam part as the shower floor element 1. It is preferably formed in the initial state, however, without openings or ribs or the like, but as a continuous plate-shaped part.

The opening 4 is then recessed throughout.

Alternatively, the gutter 12 can also stand up on the underside by means of feet 35, which are only indicated here, and / or, in particular if no underlay element 34 is provided, for example, be received and supported in a mortar bed.

In this case, the drainage channel 12 can still be located on the underside of the drainage channel 36.

Related to the Figures 13 and 14 a further preferred embodiment of a shower floor element is described, which embodiment also has significance regardless of the channel receptacle described here, for floor-level shower floor elements as such.

It is essential that underside hollow areas 17 of the shower tray element, outside a drain and optionally a drain pot and a drain line to be accommodated, are filled with a heavy material 37. The heavy material 37 may consist for example of mortar and / or tile adhesive. It may also be absorbed here, taken up by gluing, stone elements act. It can also be a screed concrete.

It is essential that the shower tray element as a whole, but optionally with a vertical subdivision as described in a first part 2 and a second part 5, is filled in the bottom of the cavity 17 with the heavy material.

In terms of production, this can be done so that the shower floor element or the first and / or the second part lying on the floor lying in reverse from above with respect to the - if not used for drain and / or drain and / or drain pot - remaining cavities 23 with the heavy material is filled and then, optionally after curing or with the interposition of a film that can be pulled out after insertion again or remains, is reversed and is inserted into a prepared area of the soil.

FIG. 15 shows a cross section through an integrally given here shower floor element with a lower, in the installed state substantially horizontally arranged surface and an upper gradient surface. The gradient is usually lower than shown here.

The shower tray element has through cavities 38, here in a cylindrical design. The cavities are filled in the installed state with a heavy material, such as tile adhesive or screed concrete. The cavities 38 may have a bottom 39.

In the FIG. 15 is further dashed lines the possible installation of a gutter part 26 shown with associated sequence.
