Description

The invention relates to an assembly system for cover elements such as window sills and other parapet, parapet and wall coverings with an edge profile, in particular a shadow groove profile.

The US 2006/236618 A1 shows a mounting device for a window frame flange on the outside of the building, which surrounds the entire window. So that the screws, which are screwed through the flange into the facade, do not make the sealing trough leaky, the flange is provided with U-profiles, which extend the flange downwards.

The US 2012/0144761 A1 branches off a sealing trough for a window sill, which is put together from side parts and a middle part. Mounting brackets for mounting are not shown. The sealing trough is plugged together and then fastened as a unit in the window opening. A shadow groove profile or an edge profile with a plaster connection edge is not available.

The WO 2014012555 A1 shows a U-profile which is inserted into the outer wall of a building and into which a cover element is inserted. A shadow groove profile or a plaster edge profile with a plaster connection edge below the cover element is not available.

The FR 1409865 A shows a cover element for a building opening, which is attached with end angles and intermediate brackets.

The DE 24 31 174 A1 shows a mounting device for a window sill in the building interior. The mounting device has a profile rail running the length of the window sill, which is concreted in with poured concrete on the parapet. The profile rail can have a plaster edge.

When installing window sills with the formation of a shadow gap, it is known to attach a shadow groove profile below the window sill to be installed later or already installed on the wall by plastering, screwing or gluing. The problem here is that the alignment of the shadow groove profile with respect to the window or the window sill is relatively complex and difficult and thus represents a considerable additional effort for the plasterer. The alignment of the edge or shadow groove profile is particularly critical when installing window sills flush with the surface, i.e. window sills whose front edge is flush with the plaster, since even slight deviations of the plaster edge or shadow gaps in height to the floor and / or in the Distance to the window are clearly visible.

The object on which the invention is based is to provide a mounting system for cover elements which enables a simple and precise alignment of a plaster separating edge, in particular a shadow joint, with the edge or shadow groove profile being able to be installed independently of the interior stucco work.

A device according to one of claims 1 or 10 is proposed for achieving the object.

The mounting system has mounting brackets, the edge or shadow groove profile being initially attached to these mounting brackets and the mounting brackets for the horizontal and vertical alignment of the edge or shadow groove profile are designed. The edge or shadow groove profile can be slipped onto the mounting bracket or attached to it by means of an adhesive, screw or rivet connection.

The device for aligning and installing an edge or shadow groove profile of a cover element for an area to be covered on a parapet, parapet or wall, comprises the edge or shadow groove profile, at least two end angles and at least one installation angle,
The end brackets are fastened opposite each other on the two lateral end areas of the area to be covered, the end brackets each having a forward leg that is aligned horizontally or approximately parallel to the cover element that is placed later and protrudes over the area to be covered before the plastering work is carried out the end brackets are fastened to at least one fastening point in such a way that the front edge of the leg protruding beyond the area to be covered has a fixed horizontal distance from the fastening point;
Each mounting bracket has a forwardly extending leg that is aligned horizontally or parallel to the later placed cover element and has a plaster leg that extends downward from the rear end of the leg and which can be fixed at a fastening point so that the forwardly extending leg has a fixed vertical distance to the Has attachment point;
the edge or shadow groove profile is attached or placed on the forward legs of the end bracket and mounting bracket, and the edge or shadow groove profile forms a plaster connection edge below the cover element.

The edge or shadow groove profile preferably has a groove which is pushed over one leg of each end bracket and mounting bracket.

With the mounting system according to the invention, the edge or shadow groove profile can advantageously be mounted with a fixed orientation to the wall opening or to the window before the plastering work is carried out.

The assembly system preferably additionally comprises means for assembling the cover element, for example clamping brackets or other mechanical holding or securing elements, so that it is fastened in or on the assembly system after the cleaning work has been completed to prevent possible damage. This damage could occur, for example, as a result of the cleaning work or the fact that the window sill is misused as a workbench on the construction site.

The assembly system according to the invention preferably forms a stable frame for the cover element, the cover element not being connected to or in contact with the plaster layer. This is achieved in that the end angles form lateral plaster connection edges and the edge or shadow groove profile forms a lower plaster connection edge. In this way, the cover element can advantageously be used after the plastering work has been carried out and can also be replaced again (e.g. if damaged) without destroying the plaster layer or the plaster edges.

Particularly preferably, all elements of the mounting system are made of plastic or sheet metal, in particular aluminum.

The edge or shadow groove profile particularly preferably consists of an extruded aluminum profile, a folded aluminum sheet, of galvanized or coated sheet steel or an extruded galvanized or coated steel profile. Whereby the edge or shadow groove profile is preferably available by the meter, which is cut to length before assembly to the length of the cover element, plus any lateral joint spacing between the cover element and the vertical legs of the end bracket.

In Fig. 1 shows an exemplary assembly system according to the invention for a cover element with a shadow gap. The mounting system according to the invention comprises at least one shadow groove profile 1, two end brackets 2 and at least one mounting bracket 3.

The assembly system according to the invention can also comprise at least one additional intermediate holder 4, which lies between the two end angles 2.

As shown, the two outer end angles 2 preferably also have a vertical leg extending forward, so that the two end angles 2 can advantageously be present as lateral end elements for the cover element, or form part of the end elements. For example, each closing element comprises a closing angle 2 and optionally a plaster edge profile 5 and optionally a seal 6 made of flexible or solid material or solid material with flexible inserts.

In the Figs. 2 to 5 the assembly of a window sill 14 with the assembly system according to the invention is shown. The window 10 has a frame 7.1 which is attached to the base profile 7. The base profile 7 is inserted into the window reveal at a distance from the wall. The lower surface of the window reveal is formed by the parapet, which denotes the area of the masonry 8 which extends between the floor and the window reveal. For example, an insulating body 9, preferably made of insulating material or a comparable material, is placed on the parapet. Alternatively the mounting system according to the invention can also be mounted directly above the masonry 8.

In Fig. 2 the first assembly step is shown, which consists of attaching the end bracket 2 and the optional intermediate bracket 4 to the base profile 7. Each end bracket 2 and each intermediate holder 4 has a forward leg, which is aligned horizontally or parallel to the cover element that is placed later, and a vertical connecting leg, which has openings through which it is screwed to the base profile 7.

In the next step, the mounting brackets 3 can be installed. The mounting brackets 3 each have a downwardly extending vertical leg, which can advantageously be designed as a perforated plate. The mounting brackets 3 also each have a second leg, which is aligned horizontally or parallel to the cover element that is placed later. The vertical legs of the mounting brackets 3 are fixed to the masonry 8 so that the legs of the mounting brackets 3, which are horizontally or parallel to the later placed cover element, lie on a plane with an exact distance from the floor. The shadow groove profile 1 is slipped onto the forward leg of the end bracket 2 and the forward leg of the mounting bracket 3 in order to connect to the in Fig. 3 shown intermediate step.

As an alternative, before assembly of the mounting bracket 3, the shadow groove profile 1 can preferably be attached to the forward legs of the end bracket 2 and intermediate bracket 4, the mounting bracket 3 already being received in the groove of the shadow groove profile 1 or being inserted into it. The front edge of the shadow groove profile 1 can now be aligned horizontally at the correct distance from the floor and the vertical legs of the mounting bracket 3 can be attached to the masonry 8 in this aligned position. The vertical legs of the mounting bracket 3 are fastened by gluing or Screwing to the masonry 8. This mounting alternative also leads to the in Fig. 3 shown intermediate step.

As in Fig. 3 is shown on the left side of the window 10, a plaster edge profile 5 can be plugged or glued onto the vertically forwards extending web of the outer end bracket 2. Alternatively, the web running vertically forwards can itself be shaped as a plaster edge profile 5.

In Fig. 4 the left end bracket 2 and its plaster edge profile 5 is already plastered in. The shadow groove profile 1 is shown partially plastered. As a result of the plastering in, the shadow groove profile 1 is fixed against the forward horizontal legs of the end bracket 2. Because both the shadow groove profile 1 and the underlying vertical legs of the mounting bracket 3 have openings, a good hold of the plaster layer 13 on the underlying masonry 8 and the insulating body 9 is ensured.

As in Fig. 4 is symbolically illustrated, adhesive beads 12 for the cover element can be applied to the insulating body 9, or another connecting or filling material can be applied. At least one clamping bracket 11 can also be attached to the base profile 7, which presses the cover element against the frame 7.1 with its area protruding upwards to the rear, so that the upper surface of the cover element rests against the underside of the frame 7.1 without any gaps.

The cover element in the form of the window sill 14 is mounted after the plastering work has been completed, that is, after the shadow groove profile 1 and the two lateral end angles 2 have been completely plastered in. For this purpose, the window sill 14 is pushed into the gap between the end brackets 2 and the frame 7.1 and pressed against the frame 7.1 by the clamping bracket 11. The front end of the window sill 14 rests on the shadow groove profile 1 and is fixed to the substrate by the adhesive beads 12.

The window sill 14 can, for example, also be permanently fixed in that the space between the window sill 14 and the insulating body 9 is provided with assembly adhesive before the window sill 14 is inserted or assembly foam is filled. If there is no insulating body 9 between the parapet and the cover element, this space can also be filled with filler or adhesive before the cover element is put on.

In Fig. 6 a section through a particularly preferred assembly system according to the invention is shown. Insofar as directions are given here and in other places in the text, "above" means away from the ground, "rear" in the direction of the base profile 7 and "front" means away from the base profile 7. The shadow groove profile 1, which is formed from sheet metal or a plastic material, has a vertical plastering section 15, at the upper end of which the shadow groove profile 1 is angled forward, wherein this forward section 16 can run parallel to the cover element and / or horizontally. The forward section 16 merges at its front end into a substantially vertical front section 17 which forms the plastered edge of the shadow gap. From the upper end of the front section 17 there is a rearwardly extending section 18 which is aligned at least approximately parallel to the forwardly extending section 16 and includes a gap with it. The upper surface of the rearwardly extending section 18 forms the underside of the shadow gap. From the rear end of the rearwardly extending section 18 there is an upwardly extending web 19 which forms the rear surface of the shadow gap and on which the cover element to be fastened later rests.

In the gap between the sections 16 and 18 protrudes a leg 20 of the mounting bracket 3, which is aligned parallel to the latter. The vertical plaster leg 21 of the mounting bracket 3 adjoins the rear end of this leg 20.

The end bracket 2 has a limb 22 running forwards parallel to limb 20 or to sections 16 and 18 and a limb 23 running upward at the rear end of limb 22. In addition, the end bracket 2 has a perpendicular to the front extending leg 24, which laterally adjoins the legs 22 and 23.

The end bracket 2 is attached to the base profile 7 with the leg 23, in particular screwed. The screw connection can advantageously take place via elongated holes so that the position of the legs 23 on the base profile 7 can be easily adapted, in particular in height. The legs 23 can advantageously be made wider than the legs 22 of the end bracket 2, or the intermediate bracket 4, or the leg 22 can be made wider in the area of the leg 23 than in its front area as in FIG Fig. 1 and 2 It can be seen that the leg 22 has an L-shaped surface. The leg 22 of the intermediate holder 4 can accordingly also have an L- or also a T-shaped surface. At those edges of the wider areas of the legs 22 which are parallel to the leg 23, the end brackets 2 and / or the intermediate bracket 4 such as the clamping bracket 11 could have an area that protrudes obliquely backwards and upwards, which presses the cover element upwards against a stop, so that the fixing of the cover element against the stop surface is advantageously carried out directly by the end bracket 2 and / or the intermediate holder 4.

As in Fig. 6 As can be seen, the limb 22 floats forward, or rests on a flexible filler or insulating material, for example an insulating body 9, so that the front end of the limb 22 can be moved in the vertical direction. The leg 22 is placed in the gap between the sections 16 and 18, so that the front end of the leg 22 rests on the inside of the section 17. As a result, the distance of the section 17 and thus also the distance of the plaster edge of the shadow gap to the base profile 7 are specified.

The leg 20 of the mounting bracket 3 also protrudes into the gap between the sections 16 and 18 and at most as far as the leg 22. The leg 20 is preferably just as thick as the gap between the sections 16 and 18 is wide, or has at least one or several areas of appropriate thickness on, for example by the sheet metal of the leg 20 having a folded back and thus thicker area at the front end. By moving the plaster leg 21 vertically along the masonry 8, the shadow groove profile 1 can be aligned in the vertical direction. As soon as the shadow groove profile 1 is aligned vertically, the plaster leg 21 is attached to the masonry 8, for example by screwing and / or gluing. For example, the plastering leg 21 can have a vertically extending elongated hole so that it can be moved along a screw and can be fixed in the desired position by this on the masonry 8.

As in Fig. 6 As can be seen, the shadow groove profile 1 can also have openings in the section 16 so that plaster can also penetrate here, for better anchoring of the shadow groove profile 1.

In Fig. 7 the assembly system according to the invention for the assembly of an edge protection profile or edge profile 25 is shown. The execution of the mounting bracket 3 and the end bracket 2 is the same as in Fig. 6 elected. Instead of the shadow groove profile 1 according to the invention, a known edge profile 25 is used. In the simplest case, the edge profile 25 is a sheet metal strip with an L-shaped cross section, as shown. The edge profile 25 is in the example of Fig. 7 with its horizontal leg placed or glued on the leg 20 of the mounting bracket 3 and the leg 22 of the or each end bracket 2. Alternatively or additionally, the edge profile 25 could also be screwed or riveted to one or more of the mounting brackets 3 and / or the end bracket 2 and / or intermediate bracket 4.
