1 shows a side view of a one-piece end rail 2 in its manufacturing and transport position according to an embodiment of the invention.

following the terms "inside" and "outside" are replaced left and right with respect to the plane of the drawing.

The one-piece graduation track 2 includes, from left to right, an upstanding first leg 4 , a horizontal second leg 6 , a stretch area 8th and an exterior ledge area 16 with a reinforcing fabric 26 ,

The first leg 4 includes in the 1 unrecognizable mounting holes, so that the one-piece finishing rail 2 can be attached to a house wall with suitable fasteners, such as knock anchors. The right outside of the first thigh 4 is in the installed state on the inside of the insulation. At the lower end of the first leg 4 closes at approximately right angles to the horizontal second leg 6 on whose top the end face of the insulation rests in the installed state. The attached to the second leg 6 subsequent expansion area 8th includes a building-side expansion wall 10 , a Dehnboden 12 and an outside expansion wall 14 to which the outer edge area 16 followed. The thickness of the building-side Dehnwand 10 , the expansion floor 12 and the outside stretch wall 14 is opposite to the thickness of the second leg 6 significantly reduced, and the Dehnwände 10 and 14 are oriented substantially downwards, and the Dehnboden 12 runs approximately horizontally. The first leg 4 , the second leg 6 , the stretch area 8th and the outer bar area 16 have been integrally connected and manufactured for example by plastic coextrusion. Here are the thighs 4 . 6 and the outer bar area 16 made of a hard, stable plastic, especially PVC, polystyrene or PU, and the expansion area 8th is from a softer, more flexible plastic, esp especially made of soft PVC or a thermoplastic elastomer. The outer edge area 16 with the reinforcement fabric attached thereto 26 is located in 1 in the pivoted-in production and transport position.

2 shows a side view of the one-piece end rail 2 in their mounting position.

In 2 is the outer bar area 16 with the reinforcement fabric attached therein 26 in the swung-out mounting position. The pivoting direction between the swiveled manufacturing and transport position according to 1 and the swung-out mounting position according to 2 is in 2 by one with the reference numeral 30 provided arrow provided.

The in the 1 and 2 exemplified outer border area 16 comprises a main body with a recess provided therein 24 , at the top of which the upper end surface 18 located in the pivoted mounting position with the top of the second leg 6 flees. On the outside of the outer bar area 16 a third leg protrudes 20 upwards, which should rest in the mounting position against the outside of the insulation. On the outside of the outer bar area 16 is also a downwardly projecting drip 22 provided on the drips in the mounting position of water and is to be prevented by the water accordingly to the underside of the one-piece end rail 2 arrives.

On the outer surface of the outer edge area 16 is the reinforcing fabric 26 fastened, with this attachment in the 1 and 2 exemplified by an ultrasonic welding 28 is executed. The reinforcement fabric 26 is on the outside of the outer edge area 16 with a direction parallel to the extension direction of the third leg 20 and the dripping nose 22 extending extent, and it extends from the outside of the outer bar area 16 up. The reinforcing fabric can be made in particular of a glass silk. The reinforcement fabric 26 is intended to be fixed with putty on the outside of the insulation.

The one-piece graduation track 2 is suitable for different plaster thicknesses, and especially for thin plaster and thick plaster.

The width of the top of the second leg 6 , the stretch area 8th and the upper end surface 18 , ie the width between the outside of the first leg 4 and the inside of the third leg 20 corresponds essentially to a conventional insulation thickness, for example, a thickness of 120 mm for a coming into use in a new construction dam or, for example, of 100 mm for a coming in a renovation Dammstoff used.

Through the stretch area 8th may be a shift of the third leg 20 opposite the first leg 4 done to the outside and inside, as it is by the flexible expansion walls 10 and 14 and the flexible floor 12 is possible. This allows on the one hand building tolerances are compensated, so for example if the actual insulation thickness deviates by a few millimeters from the prescribed insulation thickness, on the other hand movements in Putzanschlussbereich, resulting for example by temperature effects are compensated, and cleaning cracks can be reliably avoided.

When the stretch range 8th larger and possibly with a different structure than in the 1 and 2 is shown formed, so can such a large extent between the third leg 20 and the first leg 4 be achieved that the one-piece finishing rail 2 not only for a specific insulation thickness, but for several insulation thicknesses and thicknesses suitable. As a result, significant costs can be saved.

In the in 1 pivoted manufacturing and transport position shown, the reinforcing fabric 26 particularly favorable on the outer edge area 16 be applied. Furthermore, the one-piece connection rail in the in 1 shown manufacturing and transport position only a small amount of space, so that the one-piece finishing rail can be transported very space-saving, which also saves costs. The outer edge area 16 with the reinforcement fabric attached thereto 26 needs only at the construction site in the in 2 shown swung mounting position to be brought.

3 shows a side view of a one-piece end rail 32 in its mounting position according to another embodiment of the invention.

The one-piece graduation track 32 according to 3 differs from that in the 1 and 2 shown one-piece finish rail 2 in that its horizontal second leg 6 a step 34 having. Its other elements correspond to the elements of the one-piece finishing rail 2 , and these are provided with the same reference numerals.

Also the one-piece graduation track 32 has the stretch area 8th , the horizontal displaceability of the third leg 20 opposite the first leg 4 allowed, and the pivoting between the manufacturing and transport position, in which the third leg 20 , the dripping nose 22 and the reinforcing fabric 26 are substantially horizontally oriented, and the swung-out mounting position in which these elements are aligned substantially vertically, allows.

4 shows a sectional view through a thermal dam composite system 36 with the one-piece graduation track 2 ,

The thermal insulation composite system 36 is at a lower end of a house wall 38 appropriate. This is the one-piece finishing rail 2 at the bottom of the house wall 38 aligned horizontally and mechanically eg. By means of in 4 Not shown impact anchors attached. Horizontally adjoining end rails are properly connected by means of suitable connectors. Then the dam plate 40 whose thickness is equal to the width of the one-piece finishing rail 2 fits, put on and by means of a in the 4 not shown glue on the wall of the house 38 glued. Before that is the outer bar area 16 with the reinforcement fabric attached thereto 26 from the in 1 shown einwenkten production and transport position in the in 2 pivoted pivoted mounting position shown pivoted. If necessary, the outer edge area 16 with the reinforcement fabric attached thereto 26 temporarily also be pivoted outwards, as this in the 2 and 4 is shown to facilitate the placement of the thermal insulation 40 on the one-piece graduation track 2 to enable. Thereafter, the reinforcing fabric 26 from the outside with putty on the outside of the insulation 40 attached. This filler is in 4 not separate from the plaster layer 42 shown. In addition, at the top further reinforcement fabric, which is not shown, overlapping on the reinforcing fabric 26 connect and also to the heat insulation 40 be attached. After the putty has tightened or hardened, is on the outside a plaster layer 42 applied. On the plaster layer 42 can finally, for example, a in 4 not shown paint applied.

Through the stretch area 8th can the thermal dam composite system 36 work. Temperature-related expansions and shrinkages can be compensated, without causing cleaning cracks.

It is immediately apparent that such a thermal insulation composite system according to the invention 36 can be processed easily and pleasantly, that it provides a clean plaster finish, exact edges and a targeted water flow. The design of the one-piece plastic finishing rail also results in a thermal bridge reduction and an improved insulating effect.

5 shows a side view of a one-piece end rail 44 in its mounting position according to another embodiment of the invention.

The one-piece end rail corresponds to this 44 the one-piece graduation track 2 as they are in 2 shown, with the difference that its stretch area 48 not in a transition region between the second leg 6 and the outer bar area 16 is arranged, but rather at an approximately central position of the second leg, and that the second leg therefore in a building-side area 46 of the second leg, in the stretch area 48 and in an outside area 50 of the second leg is divided.

The effect of the expansion area 48 , a shift of the third leg 30 based on the first leg 4 to compensate for building tolerances during processing and to accommodate movements in the plaster connection area and, with appropriate design of the expansion area 48 To absorb insulation with different thickness, corresponds in the same way to the effect as through the expansion area 8th at the one-piece graduation track 2 provided. The rest, above with reference to the one-piece finishing rail 2 the advantages set out apply equally to the one-piece terminus 44 , and these are not listed here again to avoid repetition.

It is expressly noted at this point that the arrangement of the strain area 48 basically at any width position of the second leg is possible, and the position does not need to be centered. Similarly, the stretch area may also be further left or further to the right than this 5 is shown and even at the left end of the second leg immediately adjacent to the first leg 4 be arranged.
