Description

The invention relates to a finishing strip, in particular a finishing profile strip, in the field of building technology, in particular the building facade construction. The end bar can also be referred to as a profile skirting. A cover strip serves to receive and support a cover plate or a Abdeclcplattenanordnung for building walls, in particular building exterior walls, at the narrow end face and hold them to the building wall. The end strip, in particular made of a rigid material, such as metal or plastic, reinforces the edge region of the cover plates, which is encompassed by the end strip.

The cover plate may be a thermal insulation board, which is used for full thermal insulation on building facades. The cover plate in particular rectangular shape has narrow sides, which surrounds the end strip, in particular the lower narrow side. The cover plate can be made of foamy plastic and / or consist of a biodegradable material. A biological thermal insulation board may be, for example, a wood fiber board, which has good thermal insulation properties.

A conclusion bar is off DE 100 33 364 B4 known, which has a support web for impact receiving a narrow side of the cover plate and one of the building wall facing the mounting bar. In addition, the known end strip has a turned away from the building wall plasterboard or plaster legs, which is placed vertically and forms a cutting edge at the end, creating a clean connection of the fabric cover cover plate and spatula adhesive and plaster is to be ensured. It was found in the known end strips of the disadvantage that damage may be accompanied by cover plates, if in the wall structure, which has integrated the cover plates, should penetrate by strong and lasting applying water contrary to expectations. Thus, although it should be noted that with a proper installation of the cover plates and end strip water ingress between the building facade and the cover plates can be excluded, but can not be ruled out should there be a water entry that water accumulates in the profile area and thus could damage the cover.

In order to allow safe removal of water, which can penetrate in particular due to incorrect installation of the end strip and / or the cover plates, in particular to drain from the end strip, it is known to form several support holes in support webs, on which can run on the support web collecting water ,

However, it has been found that undesired water entry into the cover plates occurs, in particular in the case of incorrect assembly of connection parts to other components, such as window connections, shutter boxes or penetrations of all kinds (for example faucets). This water can collect in the base rails. In case of improper installation, the water can indeed drain through the drainage openings on the support web, however, it was found that frequently accompanied by rain strong winds water is prevented from draining through the drainage opening and even get back into the masonry and in the intermediate area between masonry and cover which can lead to structural damage on the facade.

It is an object of the invention to overcome the disadvantages of the prior art, in particular in case of improper installation of cover plates and / or end strip to ensure a safe drainage function optionally for entering the cover plates water.

This object is solved by the features of claim 1.

Thereafter, a closing strip, in particular a closing profile strip for cover plates in particular of the type described above, for building walls, in particular for thermal insulation boards, in particular in the manner described above, is provided. The end strip according to the invention has a support web for receiving a narrow side of a cover, a building wall facing the mounting bar, which preferably protrudes at an angle of greater than 60 ° in the vertical direction and in particular has through holes to attach the end strips to the masonry of the building can. In addition, the end strip has a plaster web averted from the building wall, wherein the mounting bar and the plaster bar are coupled to each other via the support web. Also, the plasterboard is substantially in the vertical direction at an angle greater than 60 °, preferably greater than 60 ° away from the support web. In the support web a plurality of drainage openings are formed, which may be arranged in a recurring pattern. About the drainage openings can accumulating water, which accumulates in particular due to incorrect assembly of overhead building facilities, such as gutters, etc., run off, and also splashing water that enters from below into the Abdeckplattenanordnung can run off. According to the invention, an additional flow channel web is arranged below the support web, which forms with the support web extending in the longitudinal direction of the end strip, extending substantially horizontally extending flow channel. As a result, the flow channel can be delimited by an additional subchannel plate, which is arranged in particular on the end strip, in particular substantially parallel to the support web or at least slightly inclined thereto.

With the measure according to the invention of forming a drainage channel wind influences or other impediments to the drainage influences, such as the infestation of pests, shielded, whereby an unhindered drainage of the collecting water is ensured away from the support web, whereby the standing on the cover strip cover plates of stagnant water always freed stay. It was found that even with gross installation errors of water-conducting facilities on the buildings and a large moisture on the cover plate, the water can drain safely from the end strip, which structural damage, for example by mold, can be sufficiently reliably avoided.

In a preferred embodiment of the invention, the drainage channel is arranged with respect to the drainage holes such that all of the water can be drained from the plurality of drainage holes and received by the drainage channel. The drainage channel can be closed at least on the building wall side and preferably forms on the plaster web side a longitudinally extending drainage passage, at which the received water can flow away from the end strip and the cover plate system. The drain passage is preferably delimited both by the drainage longitudinal edge of the drainage passage web and by a longitudinal edge of the cleaning web or cleaning web section. The cleaning strip section is an essentially vertical and / or horizontal angle of more than 60 ° downwardly extending web portion, the downwardly facing edge together with the axial end edge of the flow channel web in the longitudinal direction of the end strip in particular limited constant cross-section drain passage limited.

The longitudinal edge of the Putzstegabschnitts is inclined away from the building wall and is preferably bent over the rest of the particular plate-shaped Putzstegabschnitts outward of the building wall away. In a further development of the invention, the flow channel web, which forms in particular a bottom web plate of the end strip, in particular carried out so that it can rest flat on a base projection of the building wall and slightly inclined relative to a horizontal plane, with an inclination angle of less than 20 ° relative to the horizontal level is considered. Preferably, the surface of the downcomer land receiving the drained water is inclined so that the water received through the plurality of drainage openings can drain to the drain passage of the drainage channel under the influence of gravity. The water, which is led to the drain passage, is derived via the drain passage from the end bar. The drain passage is formed in particular on a cleaning ridge side longitudinal edge of the drain passage web or at an end face of the drain passage web. At the drain passage, the drainage water leaves the end bar under the influence of gravity. Although wind pressure should push the water away from the drain passage back into the drain passage land, the drain passage serves as a room divider for receiving the cover plate on the top of the landing stage. Experiments showed that even strong winds can not push the water from the drainage channel back into the Abdeckplattenaufnahme.

In a preferred embodiment of the invention, the flow channel web on the mounting web side, so the building wall facing side, fixed to the support web. Additionally or alternatively, the support web, the cleaning bar, the mounting bar and the drainage channel web can be made of one piece, in particular a piece of metal or plastic. In particular coated sheet metal parts can be considered.

In a further development of the invention, the flow channel web is mounted translationally displaceable relative to the support web in the axial direction of the end strip, wherein in particular a Axialgleitlagerung is provided, through which the flow channel web is translationally adjustable relative to the support web in the axial direction. In particular, a bearing element in the longitudinal direction has a constant profile cross-section in at least one undercut in order to ensure safe displacement of the components relative to one another in a single dimension direction, namely the longitudinal direction of the end strip. In this way, a kind of plain bearing is realized. Furthermore, a counter bearing element to the profiled bearing element complementary in shape, so be formed with a negative profile, so that the one another cross-bearing elements realize a plain bearing with translational displacement in particular only in the longitudinal direction of the end strip.

Due to the displaceability of the support channel web relative to the support web, it is possible that month-interface transitions at the axial height of the support web, such as the flow channel web, avoided, causing an unwanted ingress of water, especially from the bottom of the end bar by splashing, at least in the Cover plate receiving space is avoided.

Preferably, the Axialgleitlagerung additionally allows a permissible pivoting of the support channel web relative to the stationary support web and / or mounting web, in particular a pivotability by less than 20 ° to a parallel to the longitudinal direction of the end strip extending longitudinal axis. A pivotal movement amplitude of the axial sliding bearing is preferably limited to less than 20 °, preferably less than 10 °.

In a preferred embodiment of the invention, a pivot stop for the pivotable thrust bearing is provided, so that the support channel web at an angular position relative to the horizontal plane of less than 10 °, preferably 1 ° to 5 °, remains stationary with respect to the support web and / or mounting web, in particular, under the influence of gravity of the support channel web abuts against the pivot stop. In this way, on the one hand a stable end strip construction is realized, on the other hand, a sufficient inclination angle of the support channel web can be reliably adjusted to ensure the drainage of drainage water from the end strip and away from the cover plates to be protected safely.

In a further development of the invention, the drain passage web has a preferably vertical connection piece for the realization of a bearing element for the axial bearing between the drain passage web and the support web. The building wall facing the outside of the end piece is aligned with the building wall facing mounting surface of the mounting bar, in particular the end piece has a greater material thickness than the Ablaufkanalsteg, in particular the remaining components of the particular integrally formed end strip.

In a further development of the invention, the flow channel web extends so far in the longitudinal direction of the end strip perpendicularly in the transverse direction to a from the support web essentially vertically downwardly extending plaster web section that a Abtropflängsrand the drain channel web forms with a longitudinal end edge of the plaster web extending in the longitudinal direction of the end strip drain gap whose gap width is constant, in particular in the longitudinal direction of the end strip and / or at least greater than 1 mm and preferably less than 1 cm or 2 cm. In particular, the flow channel web extends in the transverse direction of the end strip over at least half of the transverse overall extension of the end strip towards the Puztsteg to act as a panel on the underside of the end strip and to further shield the receiving space of the cover plates.

In a further development of the invention, the plurality of drainage holes are arranged in one of the building wall facing axial half of the support web in the support web. This means that in a transverse direction division of the support web in two halves, the drainage holes are located exclusively in the longitudinal wall facing the building wall. In such an arrangement, the support web is at least partially inclined away from the building wall, wherein at a Auflagestegsenke the drainage holes are concentrated and lie in the building wall facing the longitudinal half. A montagestegseitigem section of the support web has a slope from the building wall away to the Auflagestegsenke, of which a cleaning ridge side portion of the support web has an opposite inclination towards the building wall, in particular the mounting web side slope is greater than the cleaning ridge side slope. All water that reaches the end trim is directed to the support fulcrum, from where it can drain via the drainage holes under the influence of gravity into the drainage channel. The plaster web-side transition web portion may in particular comprise a continuous inclination angle of less than 20 °, in particular 10 °.

In a further development of the invention, the sink has a sink bottom, which lies substantially in a horizontal plane. The sink bottom has a flat strip shape, in which the drainage holes are incorporated.

In a preferred embodiment of the invention, a barrier covering in particular the drainage holes is provided on the support web, in particular in the region of the drainage holes Small animals, such as insects, arranged. The barrier may be formed, for example, by a correspondingly dimensioned grid which is fastened on the upper side or the lower side of the support web. The barrier may alternatively or additionally be formed by a membrane, which in particular covers at least the plurality of drainage holes. The membrane is adapted to drain liquid through the drainage channel under the influence of gravity, with backflow towards the cover plates being blocked. The membrane may also be attached to the top or the bottom of the support web. Also, a combination of a grid and a membrane may preferably be arranged.

Furthermore, a lower portion of the cleaning ridge may have a longitudinal edge that extends vertically beyond the discharge longitudinal edge of the discharge channel web and / or includes a crimping end that extends transversely away from the building wall.

Furthermore, the invention relates to a method for mounting a terminal strip, which can be configured in particular according to the above description. The end strip is used for cover panels of building walls, in particular of thermal insulation panels, in which the end strip is formed with a support web for receiving and / or supporting the cover plate. At least the support web is provided in the axial direction with a desired axial length, in particular cut to the desired axial length. In the vertical direction, a flow channel web is provided below the support web, which is positioned and / or axially dimensioned so that it overlaps one or both axial ends of the support web in the longitudinal direction of the end strip, in particular completely overlapping in the axial and transverse directions.

Two transition regions of the support web and the flow channel web on one and the same axial height can be easily prevented.
