    FASTENING ELEMENT, ARRANGEMENT AND METHOD FOR FASTENING INSULATION PLATES
    The invention relates to a fastener with the features of the preamble of claim 1, an arrangement according to claim 8 and a method for fixing an insulating plate to a substrate having the features of the preamble of claim 9.
    Fasteners for the attachment of insulation boards are well known and are often referred to as insulation dowels. They typically have a dowel sleeve, a spreading element for spreading this dowel sleeve and a retaining plate. The retaining plate can be integral with the dowel sleeve, but from the document EP 0 644 301 B1 it is also known, for example, to provide the expansion element in one piece or fixedly connected to the retaining plate. As spreading especially screws, nails or screw nails made of plastic or metal come into question. For anchoring such fasteners, a borehole is typically created through the insulation board into the ground. Subsequently, the fastener is inserted into this hole and the dowel sleeve by driving the expansion expands. At the same time the insulation board is something used on the ground, in part, the insulation plate bulges in the region of the holding plate thereby something. Following the attachment of the insulating panels they are usually plastered over. Especially with thin plaster, there is the problem of achieving a flat surface in the area of the fastening elements. Furthermore, in some fasteners, the problem of the formation of so-called. "Cold bridges", i. the fasteners undesirably act as transmission elements for thermal energy.
    It has therefore long been known to fasten such fasteners sunk. For example, it is proposed in EP 0 086 452 B1 to mill out the insulation board in the region of the retaining plate a few millimeters, then set the anchor as described above and then place an insulating material in the milled recess on the retaining plate. The Dämmstofondondelle concludes with the insulation board, so that on the one hand, this can be well overpainted and on the other hand, cold bridges are avoided.
    To avoid the milling out the document EP 1 318 250 A2 proposes to incise the insulation plate annular and to let the retaining plate penetrate specifically into the insulation board. Again, a Dämmstofondondelle is attached afterwards. The annular separation takes place with cutting devices which are attached to the fastening element or a special tool. The setting process always takes place independently of the variant proposed in each case with a special tool that predetermines the penetration depth of the fastening element into the insulating panel via a stop.
    The invention has the object to provide a simplified setting method, an improved fastener and an arrangement with this fastener.
    This object is achieved by the fastener according to claim 1, an arrangement according to claim 8 and the method according to claim 9. Surprisingly, it has been shown that it is sufficient for recessed setting of the fastener in an insulating panel when the retaining plate is rotated during anchoring and the forces are increased to the insulation board so that the retaining plate breaks into the insulation board. The retaining plate penetrates the insulation board. By turning the holding plate creates a broken edge, which does not correspond to an ideal cylinder jacket surface, but slightly widened conically in the insertion direction. In particular, the outer break-in edge, however, largely corresponds to a circular shape and that the resulting depression in the insulation board can be very well sealed with a Dämmstoffrondelle. This is surprising in particular because it has been found that the proposed method of reducing the number of different insulating panels, that is, the thickness of the insulation material used by the AT13 907U1 2014-11-15. suitable for both fibrous and pore-marked materials. The proposed method thus requires neither the fastener nor a separate tool cutting devices.
    In order to avoid the use of any special tools, it is also important that the penetration depth can be predetermined without the known attacks on special tools. The invention therefore proposes that the fastening element itself has a stop element in such a way that the retaining plate penetrates into the insulation plate during anchoring with a defined penetration depth.
    The stop element for predetermining the penetration depth is arranged on the retaining plate. Preferably, the retaining plate is rotatably connected to the expansion element and is rotated with this relative to the dowel sleeve during spreading. In a preferred embodiment, the retaining plate is also not axially displaceable with the expansion element. This allows a simple structure. The stop element for predetermining the penetration depth can be arranged on the holding plate, for example, as a cylindrical ring facing in the direction of the dowel sleeve. The fastener is in the preassembled state, i. with preassembled expansion element in the dowel sleeve, inserted into the hole until the stop element is seated on the outside of the insulation board. In this state, the dowel sleeve is not yet gespreizt from the expansion element. However, the spreader is easily screwed or captively held by means of a locking device in a defined position to the dowel sleeve By turning the retaining plate or the spreader this is fed into the dowel sleeve. This has the effect on the one hand that the dowel sleeve is spread and thus finds support in the ground. On the other hand, the holding plate is moved in the direction of the insulating board. This first penetrates the stop element in the insulation board. As soon as the retaining plate comes to rest with its outer edge on the insulating board, the tensile forces increase within the fastening element. With a correspondingly strong torque on the expansion element of the retaining plate breaks the insulation board. As in the known fasteners Eintreibweg of the expansion element in the dowel sleeve is limited by the fact that a shoulder on the expansion element or the like. Seated on a corresponding stop surface of the dowel sleeve. This leads to a defined penetration depth, so that no special tool is necessary.
    To form the stop element according to the invention there are many alternatives. Thus, the stop element must not necessarily be arranged on the retaining ring or formed in the form of a ring. Instead of a ring, for example, individual columnar elements could be arranged on the retaining plate. It would also be possible to arrange surface-or pin-like elements radially projecting on the expansion element, which either penetrate when screwing in the expansion element in the insulation board or bent over in the direction of the retaining plate, folded or canceled.
    Likewise, there are large margins for the design of the retaining plate. On the one hand, it does not have to have a closed surface, but can be broken several times. On the other hand, an outer circumference is preferably circular, but this is not necessarily the case.
    Especially with substrates that are unsuitable for anchoring in some places, it can occur that the dowel sleeve does not find sufficient support when splaying. In this case, it may be pulled slightly out of the borehole, with the result that the penetration depth of the retaining plate in the insulation board is not sufficient for inserting a Dämmstoffrondelle. In order to visualize a correctly executed in this respect anchoring process, the invention proposes that the fastener has a control element such that the achievement of the defined penetration depth is visible in the insulation. Preferably, the control element is designed as a projection on the holding plate, which points in the opposite direction of insertion of the fastener. If this projection closes with the outside of the insulation board, this signals that the minimum penetration depth has been reached. If the control element is arranged flat on the circumference of the holding plate 2/7 Austrian Patent Office AT 13 907 U1 2014-11-15 in the sense of a portion of a cylinder surface, a Dämmstoffrondelle can be used easily. However, it is also possible to design the control element in such a way that it can be removed by hand or with a hand tool, so that no interfering geometries are present when the insulating material frond is inserted.
    The invention will be explained below with reference to an embodiment. It shows: [0013] FIG. 1 the exemplary embodiment in two perspective sectional views.
    The fastener 1 shown in Figure 1 is shown in the upper half of the figure in the state before the spread and in the lower half of the figure in the state after the spread. It is used to attach an insulating plate 2 to a substrate 3. It essentially consists of a dowel sleeve 4, in which an expansion element 5 is screwed for anchoring. At the dowel sleeve 4 opposite end of a retaining plate 6 is connected to the expansion element 5. In principle, expansion element 5 and retaining plate 6 could be integral, in the present case, the expansion element 5 is formed as a metal screw with a hexagonal head 7, which has a Torx receptacle 8. For rotationally secure connection with the retaining plate 6, the expansion element 5 could be encapsulated by the retaining plate 6. In the present embodiment, the expansion element 5 is inserted into the retaining plate 6, a hexagonal recess 9, in which the hexagonal head 7 rests, ensures the torque transmission between the expansion element 5 and retaining plate 6. A pawl 10 at the edge of the hex recess 9 causes the expansion element 5 axially is held in the holding plate 6. Furthermore, the retaining plate 6 stiffening beads 11, which extend radially outward. The outer circumference 12 of the retaining plate 6 has a bead 13 with a cross-sectionally rectangular, in the direction of the substrate 3 facing outer edge 14. Also in the direction of the substrate 3 extends from the holding plate 6 from a designed as a cylindrical ring 15 stop element. The annular stop element 15 has approximately half the diameter of the retaining plate 6. It could be just as small or larger in diameter. Also, it would not have to have a complete cylindrical surface, but only indicate this segment-like. Also extending in the direction of the substrate 3 from the retaining plate 6 from an expansion element 5 comprehensive extension 16. This extension 16 telescopically engages in a dowel sleeve 4 integrally extending sleeve-shaped receptacle 17 a. In the delivery state of the fastening element 1 shown in the upper half of the figure, the expansion element 5 is held in the dowel sleeve 4 via a latching connection 18 between the extension 16 and the receptacle 17.
    To create the attachment of the insulation board 2 on the substrate 3, the insulation board 2 is first placed on the substrate 3. If necessary, it can be glued to the substrate 3. Subsequently, a borehole 19 is created through the insulation board 2 and into the substrate 3. In this hole 19 into the fastener 1 is inserted as shown in the upper half of the figure until the stop member 15 is seated on the insulation board 2. As a result, the dowel sleeve 4 is pushed into the area of the substrate 3 in the borehole 19. Furthermore, the expansion element 5 is driven into the dowel sleeve 4 with the aid of a screwing tool until the anchoring state shown in the lower half of the figure is reached. For this purpose, the screwing tool preferably engages the Torx receiver 8, but depending on the stability of the fastening element 1, it can also start at the hexagonal recess 9. During screwing of the expansion element 5 in the dowel sleeve 4, the stop element 15 first penetrates into the insulation board 2 a. In addition, then sets the bead 13 and finally the entire surface of the entire holding plate 6 on the insulation board 2. Due to the already partial spreading of the anchor sleeve 4, this already has a certain hold in the background 3. If the expansion element 5 is driven further into the dowel sleeve 4 as intended, the insulation board 2 breaks along the outer circumference 12. The result is the burglary cone 20 shown in the lower half of the figure. The driving of the expansion element 5 in the dowel sleeve 4 is continued until the extension 16 of the retaining plate 6 is seated on a stop surface 21 in the receptacle 17 of the dowel sleeve 4. A control element 22 indicates to the user that the fastener 1 has been set correctly. It is for this purpose as a projection on the outer circumference 12 of the 3/7 Austrian Patent Office AT13 907U1 2014-11-15
    Holding plate 6 is arranged and points away from the expansion element 5. In the correct anchoring state shown in the lower half of the figure concludes the control element 22 with the outer surface 23 of the insulation board 2 from. Due to its flat, cylinder-segment-shaped design, it occupies only a small space within the break-in cone 20. As a result, an unillustrated, for example, cylindrical Dämmstoffrondelle can be easily inserted into the burglary cone 20. The Dämmstofondondelle may have a slight oversize relative to the outer periphery 12 of the retaining plate 6. As a result, a slight jamming within the break-in cone 20 is achieved. In this state, the fastener 1 is no longer visible and the outer surface 23 of the insulation board 2 can be easily plastered. For the preparation of the attachment is not a special tool, but only a conventional drill and a conventional screwing, for example in the form of a cordless screwdriver necessary. 4.7
