Description

The present invention is in the field of construction technology, in particular in the field of sealing of earth-contacting components. The present invention relates in particular to a profiled strip for holding a dimpled sheet protecting the outer wall of buildings up to approximately its upper edge.

Soil-contacting components are those components of a building, which lie in the finished structure below the earth's surface. Such components are protected against ingress of water. Regularly a bitumen layer is applied from the outside. This protective layer of the component is covered before filling at least with a dimpled sheet, which may also be formed as a drainage path. The dimpled sheet is intended to prevent objects from penetrating the water-impermeable protective layer during filling and nowadays usually consists of a plastic sheet which is provided with a large number of nubs arranged in parallel rows. The knobs are imprinted in a water-impermeable plastic plate, without this being pierced thereby. In addition to the pure mechanical protection function, the dimpled sheet can also have a water-removing function. Common, trained as drainage paths dimpled sheets have a geotextile layer applied to the front side of the knobs. In this way, a seepage space is formed between the geotextile layer and the plastic film, in which water which penetrates laterally in the direction of the dimpled sheet through the geotextile layer can seep down between the knobs. Discharge lines at the lower end of the drainage track provide for the removal of the collected water.

In the prior art, it is known, after completion of the sealing work and a material-specific waiting time to install a dimpled sheet directly in the amount of the future running ground level (GOK). The vertically hanging on the outside of the building web is attached, for example, with nails or self-adhesive dowels to this. It is also common to support the railway with wooden beams or slats. In the prior art, the length of the track is chosen such that it initially ends well above the future ground level. After filling the pit, the web is then cut off immediately above the GOK and possibly covered with an L-shaped bar. The aforementioned attachment possibilities of the web until the final filling the pit have disadvantages. When attaching the protective track, the contractor must work overhead in a basement with a floor height of around 2.50 m to both hold and nail the tracks. Wooden beams or slats to support the web hinder the backfilling and in particular the layered compaction of the backfilling. Moreover, when filling down directed, sometimes considerable tensile forces act on the web, which can lead to the failure of a makeshift holding device. Finally, the protective or drainage track slips in case of not reliable support and can not be set back to its original position without removing the filling material again.

In the case of punctual loading of the web in the region of the upper end by means of nails or, for example, self-adhesive dowels, it is also not possible to prevent the web from lifting off the wall at least in sections. As a result, can get between the individual attachment points when filling soil or masonry mortar, dirt, debris, nails and the like between the web and the wall. The actual protective function of the web is thereby undermined. Although it is known in the art to cut the web after cutting at the level of GOK and cover the resulting edge with an L-shaped profile strip. However, the profile strip is attached only after filling and can be effective only from this point in time. It should also be noted that the application of the web is performed by a different trades, as the cutting of a supernatant of the track, the filling with soil and the attachment of the L-profile strip. Experience has shown that responsibilities for construction activities distributed across different disciplines do not lead to the desired high-quality successes.

In the case of drainage paths, there is also the additional problem that contamination may occur between the geotextile material and the plastic film, which clogs the drainage path and does not ensure the drainage capacity.

The EP 1 557 499 the present applicant proposes a one-piece profile strip with a locking portion, with which a nubbed membrane having a geotextile layer is to be kept to the building cover. The profile is formed by a plurality of webs and the one-piece profile has a knobbed receptacle, the one between two juxtaposed dimpled sheets engaging engaging web has, which is pivoted into the dimpled sheet and to be secured in position by locking form-fitting elements in the upper region of the profile. For this it is necessary that the profile is elastically deformable in dimensions. After introducing the dimpled sheet into the dimpled sheet receiver, the web should be swung in by hand. It should be noted that the generic profile strips for holding dimpled sheets have a certain length, usually at least a length of 1 m. If the wall thickness of the individual webs is relatively large, the force required for swiveling can no longer be manually introduced by a user. Decreasing the length of the profile strip, the attachment of a building surrounding the circumference holder for the dimpled sheet designed consuming.

From the EP 1 557 499 Furthermore, a two-part profile strip with a first profile part and a second profile part is known, in which the first profile part forms a C-shaped receptacle opening forward, into which the second profile part with an anchoring portion can be swiveled. However, it has been found that this profile strip on the one hand leads to an inaccurate positioning of the web, since the anchoring portion bears on the underside on an inner wall of the C-shaped receptacle, but otherwise is pivotable within limits. On the other hand, the dimpled sheet can not be secured with sufficient security against slipping out. It should be noted that the introduction opening for introducing the dimpled sheet in the dimpled sheet receiving on the one hand must be so large that this allows easy insertion of the dimpled sheet, but on the other hand prevents the pulling out of the dimpled sheet at the sometimes relatively high tensile forces. For this reason, the previously known profile bar does not fully meet the requirements to be made.

At the time of the EP 1 557 499 known one-piece profile strip further attempts were made, with the aim of reducing the force required to introduce the insertion web pressure force, by local cross-sectional reduction of individual profile webs. It has been shown that the necessary cross-sectional reduction would no longer ensure a secure support of the dimpled sheets at the sometimes high tensile forces DE 4217514 A1 discloses all the technical features of the preamble of claim 1. The present invention has for its object to provide a profile strip for holding a the outer wall of buildings up to their top edge protective dimpled sheet, which allows a secure mounting of the dimpled sheet and a simple introduction of the dimpled sheet in the profile strip. Furthermore, the present invention will provide a building cover with a dimpled sheet, in which the dimpled sheet is reliably and cleanly held against the building wall and remains.

To solve the problem, a profile strip with the features of claim 1 is proposed with the present invention with regard to the profile strip. The profile strip according to the invention differs from that of the EP 1 557 499 known two-piece profile strip in that when mounted on the first profile part second profile part, the dimpled sheet receptacle opens to the first profile part and the second profile part is movable relative to the first profile part, so that by cooperation of the anchoring portion formed on a trained by the first profile part counter surface a relative movement of the first profile part to the second profile part is reduced relative to a clamping gap counter surface extending at the dimpled sheet receiving limited nip.

The profile strip according to the invention forms after assembly of the first and second profile part of a nip, in which the nubs held in the dimpled sheet receiving dimpled sheet is clamped. In the case of a tensile force on the dimpled sheet which ultimately extends downwards parallel to the contact surface, there is a relative movement of the first profile part and the second profile part, ie the second profile part is moved downwards relative to the building wall. This movement is a substantially translational movement of the profile part relative to the first profile part down. Due to this relative movement, the one-sided limited by an edge of the second profile part, the wall side an opening to the dimpled sheet receiving limited nip. Accordingly, with an increased tensile force of the dimpled sheet, a self-reinforcing clamping of the dimpled sheet received in the dimpled sheet receptacle results. As a result, the holder of the dimpled sheet is inevitably reinforced in the profile strip with increasing mechanical tensile stress of the dimpled sheet. It is then not to be feared that the dimpled sheet will be pulled out of the dimpled sheet receiver as a result of a considerable tensile force.

The nip counter surface, d. H. the mating surface to the aforesaid edge is preferably, but not necessarily, formed by the first profile part. However, it can also be formed by the building to be covered with the dimpled sheet itself or another building-resistant surface.

To achieve a purely rotational relative movement of the second profile part relative to the first profile part both can be firmly connected to each other by a hinge, but this option is not according to the invention. However, the joint can also be realized by essentially spherical surface sections, which are formed on both profiles, by joining both profile parts.

Under the harsh conditions in the assembly of the profile strip, however, such solutions have proven to be advantageous in which at least the second profile part relative to the first profile part with increasing tensile load on the dimpled sheet translationally slides down. For this purpose, the first profile part has a web which forms the mating surface and engages in the dimpled sheet receptacle when the second profile part is mounted on the first profile part. With increasing relative movement of the web penetrates deeper into the dimpled sheet recording and thus can taper their receiving space and optionally clamp the nubbed sheet recorded herein. The first profile part forms a lower contact surface, through the above-mentioned web, which is oriented obliquely upwards and against which abuts the anchoring surface which is formed by the second profile part. The surface and the lower anchoring surface can in this case lie against each other over a large area. The pivotability of the two profile parts relative to one another, which is desirable in some cases for reducing the clamping gap, can be promoted by the fact that the two profile parts abut one another only selectively (in the cross-sectional direction) by appropriate shaping, ie. H. linear in the longitudinal direction of the two profile parts.

Although the interaction of contact surface and anchoring surface can lead to a sufficient tension of the two profile parts with the interposition of the dimpled sheet in the nip. To secure this clamping but preferably a stop on the second profile part is provided, which by cooperation with the first profile part a clamping gap enlarging pivoting movement of the second profile part relative to prevents the first profile part to a pivot point formed by conditioning of the second profile part relative to the first profile part on the contact surface. This stop is regularly located at the second profile part mounted on the first profile part above the dimpled sheet receptacle and preferably abuts directly against the first profile part in the case of a pivoting movement which opens the clamping gap. The stop thus prevents pressing of the nip and favors the approach of the second profile part to the contact surface with increasing tensile force and thus a further narrowing of the nip at high tensile forces.

This stop is preferably formed by the anchoring portion, which is preferably dimensioned so that it fits into a receptacle which is formed by the first profile part and opens towards the front side in the same C-shaped manner. The anchoring portion received in the C-shaped receptacle is preferably located at its lower end against the abutment surface and has an upper end which is movable in limits relative to the C-shaped receptacle. Thus, the upper end of the anchoring portion engage around the upper end facing away from the rear abutment surface of the C-shaped receptacle. Alternatively, this end can also overlap the upper end of the anchoring section. In the latter case, the first profile part forms an upper limit for a C-shaped receptacle in which the anchoring portion is received. In the former case, the upper end of the anchoring portion engages the upper end of the first profile part.

As far as the profile strip according to the invention is described by indicating "bottom" and "top", these features relate to the orientation of the profile strip in an arrangement on the building wall. The lower contact surface is that contact surface, which is formed adjacent to the dimpled sheet receiver, which is located on the profile below. The upper contact surface and the upper anchoring surface are relatively remote from the dimpled sheet receiving.

Preferred developments of the profiled strip according to the invention are specified in the subclaims. With the invention, a building covering containing the profile strip according to the invention is claimed, which may be essential to the invention in itself.

The Fig. 1 a shows a cross-sectional view through an embodiment of the first profile part 1, which forms a flat rear contact surface 11 and two provided on the opposite side of a continuous fastening web 12 cheeks 13, 14. The upper cheek 13 initially descends at right angles from the fastening web 12, then has a roof section 15 aligned obliquely downwards relative to the contact surface 11 and an adjoining, extending parallel to the contact surface 11 upper abutment web 16, which forms opposite to the attachment web 12, an upper abutment surface 17.

The lower cheek has a very short foot section 18, which extends substantially at right angles from the fastening web 12 and also has a lower contact web 19 adjoining it. The lower contact web 19 extends relative to the contact surface 11 upwards at an angle α of about 35 °. At the inner side opposite the fastening web 12, the lower contact web has, at its front free end, a barb 20 whose locking surface extends essentially at right angles to the lower retaining web 19. At the free end of the lower contact web 19 of the barb forms a latching ramp.

The lower cheek 14 projects slightly beyond the upper contact web 16 in a direction perpendicular to the contact surface 11. The two cheeks 13, 14 form, together with the essential length section of the fastening web 12, a C-shaped receptacle 21 open towards the front. In this receptacle 21 and approximately in the middle of the middle web of the C-shaped receptacle 21, which is formed by the fastening web 12, there is a bore 22 which is provided in the longitudinal direction of the first profile part 1 at predetermined intervals.

The second profile part 2 forms a substantially U-shaped, obliquely downwardly oriented dimpled sheet receptacle 31 and lying above an anchoring portion 32 from. In the embodiment shown, the upper abutment-side boundary of the dimpled sheet receptacle 31 is formed by a web referred to below as the lower anchoring web 33, which is also part of the anchoring portion 32. This also has an upper anchoring web 34, an interposed, obliquely downwardly aligned first connecting web 35, which connects to the lower ends of the upper anchoring web 34, and a parallel to the upper anchoring web extending second connecting web 36. The connecting webs 35 and 36 can be arbitrary be configured and serve vorderst the connection between the lower and the upper anchoring web 33, 34. The obliquely slightly downwardly realized orientation of the first connecting web 35 and the orientation of the received in the C-shaped receptacle 21 anchoring portion 32 substantially parallel to the contact surface 11 and thus extending in the vertical second connecting web 36 serve the flow of water dripping from the building water. This is passed through the two connecting webs 35, 36 to the outside. The free ends of the anchoring webs 33, 34 lie substantially in a plane which also contains the lower boundary of a dimpled sheet insertion opening 37, which is formed by an engagement web 38. This extends substantially perpendicular to the planes containing the free ends respectively. Corresponding to the barb 22 of the lower contact web (19), a barb 20 can also be seen at the front free end of the lower anchoring web (33).

The engaging bar 38 is connected to the anchoring portion 32 at the lower end of the second connecting bar 36 via first, second and third receiving limiting webs 39, 40, 41. The outgoing here first receiving boundary web 39 has an orientation of the first connecting web corresponding orientation obliquely downwards, which also serves the water supply. The second receiving boundary web 40, which adjoins the outer end of the first receiving boundary web 39, extends parallel to the second connecting web 40, d. H. after installation in the vertical. The third receiving boundary web 41 extends parallel to the lower anchoring web 33.

At the free end of the engaging web 38, a thickening 42 is formed. This thickening 42 forms at the front end of the engagement web 38 to the dimpled sheet receiver 41 oriented towards enlarged contact surface for a received in the receptacle 31 dimpled sheet.

For mounting the profile strip, the first profile part 1 is first screwed to the building wall. A corresponding and introduced through the bore 22 screw is in Fig. 2 shown schematically and identified by reference numeral 43. After that, an in Fig. 2 introduced with their upper end to be recognized dimpled sheet 44 in the dimpled sheet receptacle 31 having a glued to the free ends of nubs 45 Geotextilschicht 46. The dimpled sheet insertion opening 37 may be selected with respect to the dimpled sheet 44 so that the clear distance between the front end of the engaging web 38 and the front end of the lower anchoring web 33 is slightly greater than the height the dimpled sheet 44 is. In the embodiment shown, this distance is chosen to be 7.7 mm, whereas the dimpled sheet 44 with geotextile layer 46 has a height of 7.1 mm. The introduction can also be done from the front side of the profile part 2 ago. In this case, the front end of the dimpled sheet receptacle 31 is brought to the upper end of the dimpled sheet 44 to cover and pushed the second profile part 2 in its longitudinal direction on the dimpled sheet 44. By pivoting the second profile part 2 with respect to the dimpled sheet 44, the engagement web 38 is forced between two adjacent rows of dimples 45 with the interposition of the geotextile layer 46. In this case, a clamping gap 100 formed between the lower end of the dimpled sheet receiver 31 and a closure web 47 formed as an extension of the fastening web 12 is reduced. In the embodiment shown, a clamping gap counter surface 47a forming the rear boundary of the clamping gap 100 is formed by the front side of the closure web 47. If the tensile force applied to the dimpled sheet 44 increases, on the one hand the second profiled part 2 is pulled down relative to the first profiled part 1. In addition, the tensile force wants to pivot the second profile part relative to the first profile part about a pivot point, which is formed by conditioning of the two parts 1, 2 in the region of their barbs 20. The direction of rotation of such an induced pivoting movement is shown in the illustration Fig. 2 the counterclockwise direction. The thus relatively moving second profile 2 encounters this with its thus forming a stop upper anchoring web 34 against the mounting web 12 and thus prevents an enlargement of the nip 100. The second profile is then pressed with its third recording boundary web 41 against the dimpled sheet 44. The thickening 42 prevents this, that the lower engaging web 38 injured or even severed the dimpled sheet.

The dimpled sheet 44 is then already held in the longitudinal direction, ie in the vertical, immovably in the second profile part 2. This is now used together with the dimpled sheet 44 in the first profile part 1. For this purpose, the upper anchoring web 34 is first introduced into the C-shaped receptacle 21. The anchoring portion 32 is raised relatively far in the C-shaped receptacle 21 until the lower end of the lower anchoring web 33 can pivot over the upper end of the lower abutment web 19 into the C-shaped receptacle 21. Thereafter, the second profile part 2 is released.

The latching ramp of the anchoring-side barb 20 now slides on the corresponding counter-ramp of the lower contact bar 19. In this case, the distance between the front end of the engaging web 38 and the lower cheek 13 projecting lower side projection 37 of the mounting web 12 is reduced. As the sliding movement progresses, the latching surfaces provided on the barbs 20 engage behind one another. The lower anchoring web 33 slides here on the formed by the lower abutment web 19 lower abutment surface 19a, which extends with its contact surface forming barbs 20 between their barbs 20 and the foot portion 18, the contact bar 19 slides by conditioning his barbs 20 at a lower An anchoring surface 33 a, which is formed by the anchoring web 33 between the barbs 20 and the fastening-side end of the anchoring web 33. Finally, the upper anchoring web 34 is clamped against the fastening web 12 and the geotextile layer between the extension 47 and the engagement web 38. Without too much pulling force, which can sometimes lead to an elastic deformation of the force-transmitting parts of the first and second profile part 1, 2, remains in recorded in the C-shaped anchoring portion 32 between the end of the engaging ridge 38 and the first profile part 1 a to the Knob sheet receptacle 31 leading passage, in which the plastic material of the dimpled sheet 44 and the geotextile layer 46 applied thereon find place, but which is substantially smaller than the clear height of the respective knobs 45.

In the in the Fig. 1 and 2 embodiment shown results due to the barbs 20 a direct contact between the abutment-side barbs 20 and the opposite lower anchoring surface 33a on the one hand and the anchoring web-side barbs 20 and the contact-side bearing surface 19a on the other. Due to the relatively high rigidity of the dimpled sheet, it may be that this raises the second profile part 2 relative to the first profile part 1 when filling a pit. Due to the two barbs 20, however, it is prevented that the second profile part is in this case forced out with its anchoring portion 32 from the C-shaped receptacle 21.

The two first and second profile parts 1, 2 are formed as profiles of substantially equal thickness. Preferably, the profile are produced by extrusion of aluminum. However, it is also conceivable to manufacture these profile parts 1, 2 also from a plastic.

As Fig. 2 illustrates, the clear distance between the lower anchoring web 33 and the third recording boundary web 41 is selected so that the recorded in the Noppenbahnaufnahme 31 nub row with their respective nubs 45 well between the lower bearing web 19 and the third recording boundary web 41 place. The length of the third receiving boundary web 41 is selected so that the corresponding row of nubs is held with a little play in the longitudinal direction of that portion of the dimpled sheet 44, which is located in the dimpled sheet receptacle 31. The length of the second receiving boundary web 40 also contributes to this game.

The Fig. 3a and 3b show a further embodiment of a profile strip with first and second profile parts 1, 2. Also, the same parts are compared to the first embodiment with the same reference numerals.

The first profile part 1 is substantially identical to the first profile part of the first embodiment discussed above. The only difference is that the upper contact surface 17 on the inside, d. H. in the direction of the fastening web 12, a stop 48 which forms a stop surface facing the receiving opening of the C-shaped receptacle 21 and extending substantially at right angles to the upper abutment surface 17.

At the in Fig. 3b shown second embodiment of the second profile part 2, the first and the second connecting web of the previous example as a uniform straight through, but much shorter connecting web 35 are realized. This has over the first connecting web 35 of the first embodiment, a stronger downward slope. Again, however, the connecting web 35 connects the lower end of the upper anchoring web 34 with the upper end of the lower anchoring web 33. The thus anchored anchoring portion 32 has in the embodiment shown a perpendicular from the lower end of the upper anchoring web 34 outgoing therefrom spacer web 49th Das free end of this spacer web 49 is located in the plane in which also the free end of the engaging web 38 and the free end of the lower anchoring web 33 is located. The upper anchoring web 34 is offset from this plane to the front. The spacer web 39 thus forms at anchor in the C-shaped receptacle portion 32 of the second profile part 2 a contact surface, by which an excessive pivoting of the second profile part 2 relative to the first profile part 1 is avoided. The spacer web 49 abuts against the front side of the fastening web 12 even with smaller pivoting movements.

The introduction of the dimpled sheet into the dimpled sheet receptacle 31 and the introduction of the second profiled part 2 with its anchoring portion 31 in the C-shaped receptacle 21 as described above with reference to the first embodiment. After introduction, the second profile part 2 is fixed relative to the fixed first profile part 1. The upper free end of the upper anchoring web 34 slides on the stop 48 and engages behind it. When clamped between the front end of the engaging ridge 34 and the extension 47 dimpled sheet which forms an upper anchoring surface upper end of the upper anchoring web 34 slightly below the abutment surface of the stop 48 on the upper abutment surface 17 flat. Likewise flat, the lower anchoring surface 33a abuts against the lower contact surface 19.

In the second exemplary embodiment, the first profile part 1 has an anchoring section 32, which is received in the C-shaped receptacle 21, and the oblique surface 50 assigned to the spacer web 49, which is formed on the fastening web 12 on the receiving side. At high tensile load on the dimpled sheet 44 and, accordingly, excessive settling movement of the second profiled part 2 relative to the first profiled part 1, the spacer web 49 slides with its free end face on this inclined surface 50 and thus strengthens the system between the lower anchoring surface 33a and the lower abutment surface 19a.

When recorded in the C-shaped receptacle 21 anchoring portion 32 is drained from the first profile part 1 outside rainwater via the connecting webs 35-36 and over the receiving boundary webs 39-40 outside of the C-shaped receptacle 21 over. Thus, it is prevented that rainwater catches in the C-shaped receptacle 21 and causes corrosion there. The contact surface 11 may further by a in FIG. 3a indicated ridge be projected on the back, which press in a applied to the building exterior wall bitumen layer and thus better seals the underlying part against penetrating between the first profile part 1 and the building wall moisture.

In case of excessive pulling movement on the in Fig. 4 not shown dimpled sheet is drawn here also the second profile part 2 relative to the first profile part 1 down and thus reduces the nip 100. Due to the flat contact of the lower anchoring web 33 on the lower contact web 19, the second profile 2 is not so much inclined to a pivoting movement in the counterclockwise direction as in Fig. 2 profile part shown. Should it nevertheless come to a corresponding pivoting movement, the spacer web 49 forms a stop by which this pivoting movement is limited. The inclined surface 50 and the wall thicknesses of the second profile part 2 can be chosen otherwise that sets in excessive tensile load elastic deformation of the second profile part 2, through which the second profile part 2 is clamped to the first profile part and thus both parts of 1.2 be fixed.

This in Fig. 5 shown third embodiment corresponds essentially to the in Fig. 2 shown embodiment. Identical parts are also identified here with the same reference numerals. Instead of two barbs, the lower contact web 19 forms a trough 52, in which a correspondingly formed on the lower anchoring web 33 convex projection 53 is engaged.

A further simplified embodiment is in Fig. 6 shown. In this case, a C-shaped receptacle of the first profile part 1 is dispensed with. Also, the second profile part 2 is formed much simpler and has only the Noppenbahnaufnahme 31 surrounding walls 33, 38 - 41 and a stop forming upper anchoring web 34 which is formed in a straight continuation of the first receiving boundary web 39. To increase this stop the upper anchoring web 34 is slightly bent upwards.

At the in Fig. 7 the embodiment shown, the second profile part 2 has a substantially C-shaped basic shape. Of the anchoring section is only the lower anchoring web 33 formed, which limits the Noppenbahnaufnahme 31 as it were. This lower anchoring portion 33 is displaceably guided in an obliquely upwardly inclined guide, which is bounded on the underside by the lower contact surface 19a and the upper side by a guide surface 54 extending parallel thereto, which is formed by a guide web 55. In this embodiment, essentially only a translational relative movement of the second profile part 2 relative to the first profile part 1 is permitted. When applied by the dimpled sheet tensile force of the gap 100 is reduced in the manner already described and held the dimpled sheet with increasing force.

At the in Fig. 8 shown sixth embodiment, the first profile part 1, in turn, a the first embodiment of Fig. 1 and 2 corresponding basic form. The lower contact web 19, however, forms an obliquely upwardly facing drain ramp 56. The run-down ramp 56 opposite the front of the lower contact web 19 is, however, straight. In the first profile part 1, the obliquely downwardly open dimpled sheet receptacle 31 has a U-shape, wherein the inward leg of the U to the formation of a lower anchoring web 33 is inwardly folded around the end and rests against the drain ramp 56. The lower anchoring land 33 extends substantially perpendicular to the drain ramp 56.

Contrary to the representation after Fig. 2 shows the dimpled sheet 44 with its nubs to the building wall, ie to the contact surface 11. The last nub 45 of the dimpled sheet 44 is located in the dimpled sheet receiving 31, which is made possible by appropriate dimensioning of the lower anchoring web 33. A base 57 of the dimpled sheet 44 connecting the dimples 45 lies at least partially against the front side of the lower abutment web 19. With increasing relative movement of the second profile part 1 down, the lower anchoring web 33 slides on the drain ramp 56 from. As a result, the distance of the engagement web 38 is reduced to the flat bottom of the lower contact web 19. Finally, the engagement web 38 clamps the base 57 of the dimpled sheet 44 to the front of the lower abutment web 19. In this case, the size of the nip 100 is reduced to the thickness of the base 57.

For better transmission of the tensile force generated by the dimpled sheet 44 on the second profile part 2, the topmost nub 45 may be held in a form-fitting manner on the second profile part 2. For example, an accumulation of material may be provided on the dimpled sheet receptacle 31 on the inner side of the lower anchoring web 33, against which the uppermost dimple 45 of the dimpled sheet 44 abuts with a sufficient distance from the upper end of the lower abutment web 19, so that a relative movement until complete Clamping the dimpled sheet between the two profile parts 1, 2 is possible without the topmost knob against the lower abutment web 19 abuts.

Claims (17)

1. Profile strip for supporting a dimpled sheet (44) protecting the outer wall of buildings up to its upper edge, having a first profile part (1) that forms a rear contact surface (11) for contacting the wall and a second profile part (2) that has a dimpled sheet receptacle (31) and an anchoring section (32) that has a lower anchoring bar (33), wherein the dimpled sheet (44) is a plastic sheet that is provided with a plurality of dimples (45) arranged in parallel, wherein an upper end of the dimpled sheet (44), that is a row of dimples, can be inserted into the dimpled sheet receptacle (31), wherein, at the first profile part (1), a counter surface (19a) is formed by a bar (19) engaging into the dimpled sheet receptacle (31), wherein, in the second profile part (2), which is mounted on the first profile part (1), the dimpled sheet receptacle (31) opens towards the first profile part (1), and the second profile part (2) can be moved relative to the first profile part (1), characterised in that, through cooperation of the lower anchoring bar (33) of the anchoring section (32) on the counter surface (19a) in a translational downward sliding relative movement of the first profile part and the second profile part (1, 2), a clamping gap (100) delimited by a clamping gap counter surface (47a), which is preferably formed by the first profile part (1) and a lower boundary (42) of the dimpled sheet receptacle (31), is reduced by a tensile load of the dimpled sheet (44).
2. Profile strip according to claim 1,
   characterised in that
   the first profile part (1) forms a lower contact surface (19a) that is oriented obliquely upwards, and in that the second profile part (2), when the second profile part (2) is mounted on the first profile part (1), forms a lower anchoring surface (33a) resting against the lower contact surface (19a).
3. Profile strip according to claim 2,
   characterised in that
   the lower contact surface (19a) and the rear contact surface (11) enclose an angle (α) of between 30° and 50°.
4. Profile strip according to any one of the preceding claims 2 or 3,
   characterised in that
   the second profile part (2) forms a stop in (34) that, when the second profile part (2) is mounted on the first profile part (1), cooperates with the first profile part (1) to prevent a pivot movement of the second profile part (2) relative to the first profile part (1) about a pivot point formed by the contact of the second profile part (2) on the lower contact surface (19a), said pivot movement enlarging the clamping gap (100).
5. Profile strip according to any one of the preceding claims 1 to 4,
   characterised in that
   the first profile part (1) forms a receptacle (21) that opens towards the front in a C-shaped manner, and in that the anchoring section (32) is dimensioned so that it can in any case be partially inserted into the receptacle (21) and can be locked therein in a form-fitting manner.
6. Profile strip according to claim 5,
   characterised in that
   the C-shaped receptacle (21) has an upper contact surface (17) on its upper region that, when the anchoring section (32) is accommodated in the C-shaped receptacle (21), cooperates with an upper anchoring surface that is formed by the anchoring section (32).
7. Profile strip according to any one of claims 5 or 6,
   characterised in that,
   when the anchoring section (32) is accommodated in the C-shaped receptacle (21), the first and the second profile part (1, 2) are fixed, by form-fitting parts (20, 34, 48) provided between the two profile parts (1, 2), against one another in the direction of movement counter to the tensile force of a dimpled sheet (44) accommodated in the dimpled sheet receptacle (31).
8. Profile strip according to any one of claims 2 to 4,
   characterised in that
   the lower anchoring surface (33a) and the lower contact surface (19a) have cooperating form-fitting elements (20).
9. Profile strip according to claim 8,
   characterised in that
   a barb (20) is formed at the front end of the lower contact surface (19a) and/or the front end of the lower anchoring surface (33a).
10. Profile strip according to any one of claims 5 to 7,
    characterised in that
    the upper contact surface (17) is delimited by a stop (48) that, when the anchoring section (32) is accommodated in the C-shaped receptacle (21), is situated directly above the upper end of a lower anchoring bar (33) forming the lower anchoring surface (33a).
11. Profile strip according to any one of the preceding claims 2-4, 8 or 9,
    characterised in that
    the dimpled sheet receptacle (31) has a dimpled sheet insertion opening (37) that is delimited on the upper side by a lower anchoring bar (33) forming the lower anchoring surface (33a) and on the lower side by an engaging bar (38) forming the lower end of the second profile part (2).
12. Profile strip according to claim 11 and any one of claims 5 to 7, 10,
    characterised in that,
    when the anchoring section (32) is accommodated in the C-shaped receptacle (21), a passage leading to the dimpled sheet receptacle (31) is formed between the end of the engaging bar (38) and the first profile part (1).
13. Profile strip according to claim 11 or 12,
    characterised in that
    the engaging bar (38) has a thickening (42) at its free end.
14. Profile strip according to any one of the preceding claims 5 to 7, 10,
    characterised in that
    the upper anchoring surface is formed on an upper anchoring bar (34) that extends substantially parallel to the contact surface (11) when the anchoring section (32) is accommodated in the C-shaped receptacle (21) and that is arranged at the upper end of an obliquely outwardly inclined connecting bar (35) and is connected thereby to the lower anchoring bar (33).
15. Profile strip according to any one of the preceding claims,
    characterised in that
    the anchoring section (32) has an upper anchoring bar (34) that rests against the first profile section (1) under a preload when the form-fitting parts are effective.
16. Profile strip according to any one of the preceding claims 2-15,
    characterised in that
    the lower anchoring section (33) is displaceably guided between the lower contact surface (19a) and a guide surface (54) extending substantially parallel thereto.
17. Building cover for protecting an outer seal applied on a building wall, comprising a dimpled sheet,
    characterised in that
    the dimpled sheet (44) is held at its upper end in a profile strip according to any one of the preceding claims.
