Definitions

  • the invention relates to a device and a method for forming a connection of a single or multilayer plaster layer to a sheet metal storage. Such connections must be made in the area of building facades.
  • the building façade can comprise, for example, a composite thermal insulation system with an exterior single-layer or multi-layer plaster layer, which is to be connected to sheet metal storage in a base area of the building façade. Since it is a plaster layer and a sheet metal storage to different materials, which in particular have a different thermally induced expansion behavior, the plaster layer to form a watertight transition can be brought neither directly to the sheet metal storage, nor be guided to the sheet metal storage. Because a corresponding execution of the transition would lead to cracks in the connection area and thus to leaks in the long term.
  • connection and transition profiles are already known, which can be used in the area of a material change within a building facade.
  • the applicant himself offers a profile for forming a transition to sheet-metal custody in facade insulation systems, which has a clamping portion for receiving the sheet metal storage and a thereto attached leg for the connection of a single or multi-layer plaster layer of Fassadendämmsystems.
  • the connection to the plaster layer is produced by passing the single-layer or multi-layer plaster layer over the leg, ie plastering the leg.
  • the connection of the sheet metal storage poses again and again as a problem.
  • the present invention is therefore an object of the invention to provide a device for forming a connection of a single or multi-layer plaster layer to a sheet metal storage, which allows a simplified version of such a connection to ensure in this way in particular the tightness of the connection. Furthermore, a method for forming a connection of a single or multi-layer plaster layer to a sheet metal storage is to be specified, which is easy to carry and has a permanent as possible tight connection to the result.
  • connection profile with a first leg for connecting the plaster layer and a second leg for connecting the sheet metal storage, and connecting means, wherein the connecting means an adhesive tape for connecting the sheet metal storage with the second leg of the connection profile.
  • the adhesive tape may be a separate component of the device or already connected to the connection profile.
  • the proposed device can therefore be designed in one or more parts.
  • the connection profile and the adhesive tape are preferably available by the meter and are cut to length on site. For storage and transport reasons, the connection profile should as far as possible not exceed a length of 250 cm, while the adhesive tape can be kept in roll form.
  • the one-piece design of the device proves to be particularly advantageous, in which the adhesive tape is already connected to the connection profile. Because with cutting the profile at the same time the tape is cut to length, so that one step can be saved.
  • the attachment of the adhesive tape on the connection profile can already be done in the factory, d. H. in favorable conditions, when comparing the conditions in the factory with those at a construction site.
  • the connection of the adhesive tape to the connection profile in the factory can be carried out in particular cleaner and more precise.
  • the adhesive tape is preferably connected to the connection profile in such a way that a section of the adhesive tape intended for connection to the sheet metal storage unit projects beyond the second leg and is protected on the adhesive side by means of a peelable film.
  • the adhesive tape is preferably a single-sided adhesive butyl tape with a metallic coating.
  • Such an adhesive tape proves to be particularly robust and resistant to moisture and UV light, making it a durable dense connection or transition allows. It also has a certain elasticity to compensate for thermal stresses due to thermally induced changes in length of sheet metal storage.
  • first and the second leg of the connection profile are aligned in parallel.
  • This allows the connection of a single or multi-layer plaster layer to a parallel-guided sheet metal storage, for example, to a base plate.
  • the first and the second leg are in a plane, so that the connection profile can be fastened to an on-site substrate such that the first and the second leg lie flat on the ground.
  • the attachment of the connection profile on the substrate is preferably carried out by means of fastening means, for example in the form of dowels and / or screws. Depending on the particular nature of the substrate, the attachment can also be produced via an adhesive bond.
  • the connection profile between the first leg and the second leg has a web for forming a plastering edge and / or a drip edge.
  • the plastering edge holds the single or multi-layer plaster layer, which is brought up to the plastering edge.
  • the web arranged between the first and the second limb of the connection profile can form a drip edge.
  • the web has an angled portion which encloses an angle ⁇ with the second leg of the connection profile.
  • the angle ⁇ is preferably less than 90 °, more preferably less than 60 °.
  • the angle ⁇ can be 45 °.
  • the angled region of the web is guided over the second limb so that the adhesive tape partially comes to lie below the angled region.
  • Surface water draining over the plaster layer is thus led over the drip edge over the adhesive tape connection, so that a constructive moisture protection is provided.
  • the web preferably has a region extending perpendicularly to the first and / or second limb, to which the angled region adjoins.
  • the first leg of the connection profile which serves to connect the plaster layer
  • fasteners such as screws, can be used to attach the connection profile to a substrate.
  • the connecting means comprise a Arm michsgewebestsammlung which is connected to the first leg of the connection profile.
  • the Arm michsgewebesammlung serves - analogous to the optionally provided in the first leg openings - the optimization of the bond between the connection profile and the plaster layer. Because even the Arm michsgewebestsammlung is penetrated during plastering of the plaster and causes in this way a positive connection.
  • the Arm michsgewebestsammlung is preferably arranged parallel to the first leg of the connection profile, for example, laid flat on the first leg and secured thereto.
  • a glass fiber fabric is used as reinforcing fabric strip, since such fabrics are commonly used as reinforcing fabric in plaster layers.
  • connection profile itself is preferably made of plastic.
  • Plastic profiles are simple and inexpensive to produce and also insensitive to moisture, so that the connection profile without hesitation in a building facade, ie in the outdoor area, can be used.
  • connection profile has a structuring in the form of a grooving or corrugation.
  • the structuring is preferably formed in a surface area, which is covered after the formation of the connection of the single or multilayer plaster layer. By applying the plaster compound, this then penetrates into the recesses of the structuring, so that a positive connection between the connection profile and the cured plaster or the plaster layer is effected.
  • the structuring is preferably provided in the region of a plastering edge and / or drip edge of the connection profile formed on a web, ie. H.
  • connection profile is freely selectable, whereby it is basically in a first step to attach the connection profile to a substrate.
  • attaching the connection profile of the device can be attached to an existing sheet metal storage. If such is not yet available, the terminal block is attached and in a subsequent step the Sheet metal storage brought up to the connection profile.
  • the connection profile and the sheet metal storage may also have a common overlap region, for example by the sheet metal storage is at least partially performed over the second leg or the second leg of the connection profile is at least partially pushed under the sheet metal storage.
  • the sheet metal storage and the second leg of the connection profile are preferably pushed only to form a slight gap or jointless.
  • connection profile is fastened by means of fastening means in the form of dowels and / or screws, and / or by means of an adhesive bond to the substrate.
  • fastening means in the form of dowels and / or screws, and / or by means of an adhesive bond to the substrate.
  • the choice of fasteners depends, inter alia, on the particular existing substrate. This may for example consist of a solid or designed as a stud structure supporting wall, applied thereto plaster base plate, an insulating layer and / or a plaster layer.
  • connection profile is attached to a flush layer serving as a substrate.
  • a flush layer serving as a substrate.
  • the substrate is particularly flat and only one connection of serving as a topcoat topcoat to the sheet metal storage is to produce.
  • the first leg of the connection profile can be plastered.
  • an adhesive tape is used, which is either already connected to the second leg of the connection profile and thus an integral part of the device or is kept separately. If the latter is the case, will preferably when connecting the adhesive tape to the second leg of the connection profile at the same time made the connection with the sheet metal storage.
  • a single-sided adhesive butyl adhesive tape is used with a metallic coating for producing the compound with the sheet metal storage.
  • Such an adhesive tape is robust and insensitive to moisture and therefore particularly suitable for outdoor use.
  • such an adhesive tape has a certain elasticity, so that it is able to compensate for stresses occurring due to thermally induced changes in length of the sheet metal storage.
  • the adhesive tape is used for bridging a joint area between the second leg of the connection profile and the sheet metal storage.
  • a sealing of the joint area is effected and achieved in the episode a tight connection.
  • the second leg of the connection profile and the sheet metal storage are preferably adjacent to one another, so that the adhesive tape can be guided over the joint area as evenly as possible.
  • Such a connection also satisfies high design requirements.
  • the sheet metal storage can serve, for example, to seal a socket area and / or dress.
  • the sheet metal storage is done - at least in the area of the connection to the plaster layer - parallel to the plaster layer.
  • the connection of a plaster facade to an adjacent flat roof or to an adjacent terrace can be produced via the sheet metal storage.
  • the adjacent roof surface may also be inclined.
  • the in the FIGS. 1 and 2 illustrated inventive device has a connection profile 3 3 with a first leg 3.1 and a second leg 3.2, which are arranged in this case in a plane. Between the two legs 3.1, 3.2, a web 6 is arranged, which forms a plastering edge 7 and a drip edge 8. To form the drip edge 8, the web 6 has an angled region 9, which is attached to the plastering edge 7. The angled portion 9 of the web 6 and the second leg 3.2 together enclose an angle ⁇ , which in the present case is 45 °.
  • the height h 1 of the first leg 3.1 is approximately the same size as the height h 2 of the second leg 3.2.
  • the total height h G is approximately 40 mm.
  • the connection profile 3 has in the region of the legs 3.1, 3.2 a thickness s 1 and in the region of the web 6 a thickness s 2 , wherein s 2 corresponds to approximately twice s 1 .
  • the thickness s 1 is presently 1.2 mm (see FIG. 1 ).
  • the in the FIGS. 1 and 2 Device according to the invention further comprises connecting means 4 which comprise an adhesive tape 5 connected to the second leg 3.2 of the connection profile 3 and a reinforcing fabric strip 11 which, unlike the adhesive tape 5, is fastened to the first leg 3.1 of the connection profile 3. Both the tape 5, as Also, the Arm istsgewebestsammlung 11 are beyond the respective leg 3.1, 3.2 out, so that they each form a kind of connection lug (see FIG. 2 ).
  • the Arm istsgewebestMake 11 serves to connect the connection profile 3 with a single or multi-layer plaster layer 1, which is this zoom out over the first leg 3.1 to the Anputzkante 7 or to the drip edge 8 zoom.
  • the applied to the first leg 3.1 and the Arm michsgewebestsammlung 11 plaster mass penetrates the fabric structure and causes in this way a positive connection.
  • a corresponding effect have openings 10, which are presently formed in two rows in the first leg 3.1 of the connection profile 3 (see FIG. 2 ).
  • the apertures 10 serve to receive fastening means 14 in order to fasten the connection profile 3 to a substrate 13.
  • connection profile 3 in particular in the area of the plastering edge 7 and / or the drip edge 8, the connection profile 3 in the present case has a structuring 12 in the form of a grooving in this surface area.
  • the adhesive tape 5 projecting beyond the second leg 3. 2 has an end section which is guided under the drip edge 8. In this way, a constructive moisture protection is effected. Because when installing the device in a building facade of the first leg 3.1 is above the second leg 3.2 to lie, so that the angled portion 9 has to form the drip edge 8 down and covers the end portion of the adhesive tape 5. Expiring surface water is therefore removed via the drip edge 8, without coming into contact with the end portion of the adhesive tape 5.
  • the portion of the adhesive tape 5 extending beyond the second leg 3. 2 serves for the connection to a sheet metal storage 2, which is guided parallel to the plaster layer 1 and abuts the connection profile 3 in the region of the second leg 3.
  • a small butt joint is preferably formed in order to allow movements of the sheet metal storage, which are due to thermally induced changes in length of the sheet.
  • the joint area 16 or the butt joint is bridged by the adhesive tape 5, so that a tight connection is ensured.
  • FIG. 3 shows the device as part of a building facade.
  • the device serves to connect a single-layer or multi-layer plaster layer 1 to a sheet metal storage 2.
  • connection profile 3 of the device is first attached to an on-site substrate 13 using fastening means 14 in the form of screws.
  • the on-site substrate 13 is formed by a load-bearing wall construction 17, an insulating layer 18 applied thereto and an in-wall layer 15.
  • the flush layer 15 is followed by an outer layer 19, which is to be connected to a sheet metal storage 2, which forms the lower end of the building facade.
  • the sheet metal storage 2 is brought up to the second leg 3.2 of the connection profile 3, with the formation of a small butt joint, so that an end section of the sheet metal storage 2 engages under the adhesive tape 5. Subsequently, a protective film is removed, which protects the projecting beyond the second leg 3.2 adhesive portion of the adhesive tape 5, and pressed the adhesive tape 5 to the sheet metal storage 2.
  • the connection of the connection profile 3 to the sheet metal storage 2 is made.
  • plaster compound is applied and pulled over the first leg 3.1 of the connection profile 3, so that the first leg 3.1 including the Arm michsgewebestsammlungs 11 completely in the Putz harsh 1 is embedded.
  • the plastering edge 7 or the drip edge 8 can serve as a spoiler edge.
  • the topcoat layer 19 is brought up to the drip edge 8, so that the angled region 9 is completely covered by the plaster layer 1.
  • the structuring 12 in the form of the grooving formed in this area promotes the adhesion of the plaster layer 1 to the web 6.
  • the plaster layer 1 or the top layer 19 can also be brought up to the plastering edge 7.
  • FIG. 4 For comparison, an earlier connection or transition profile 3 of the applicant is shown. This is attached directly to an insulating layer 18 as a substrate 13. In turn, screws serve as fastening means 14.
  • the transitional profile 3 has a first leg 3.1, to which at a distance a second leg 3.2 is attached to form a clamping portion.
  • the clamping portion receives a sheet metal storage 2, which is plugged into the intermediate space between the first and the second leg 3.1, 3.2 for this purpose. Since the size of the gap is predetermined, the sheet must not exceed a certain strength. It is problematic when the sheet is folded one or more times and thus at least twice. If there is still the connection to lead an inner corner of the building facade, the problems represent almost insoluble, if at the same time a tight connection should be effected.
  • transition profile 3 also has the disadvantage that both the first and the second leg 3.1, 3.2 serve the connection of the plaster layer 1. At least the topcoat layer 19 is for this purpose brought up to an end side on the second leg 3.2 scheduled web 6, which at the same time forms a plastering edge 7. The pinching of the sheet metal storage 2 in the clamping portion of the transition profile 3 can now cause that, depending on the number of sheet metal layers of the second leg 3.2 is pressed to the outside. This in turn leads to unevenness within the plaster layer. 1
  • the sheet metal storage 2 can have no influence on the flatness of the plaster layer 1.
  • the use of a device according to the invention therefore leads not only to a dense, but also to a visually appealing transition.
