The technical field

The present invention relates to a fastening element and method for flush mounting insulation Board on the supporting structure. The fastening element includes a clamping disk and executed along with him dowel sleeve for receiving the spacer element with a head spacer element, and the dowel sleeve has a spacer area, and the insulating plate cut the recess by means of milling.

The level of technology

From patent document EP 0086452 known method, in which simultaneously with the drilling grooves for dowels is a recess in the insulating plate for the reception of the dowel. In this case, using a diverticulum that contains the milling head and the disk stops, when drilling grooves in a single operation simultaneously in the insulating plate is cut out milling a recess corresponding to the diameter of the clamping disk, and then this recess is filled with a cover or lid that is already on prijemnom disk. Due to this decision when installing the fastener eliminates additional operation. However, milling removes quite a large number of insulating material. When a large number of anchors, which is typically used for attaching insulation boards when building a house, milling dust causes significantly the pollution and in large quantities can also harm the health of construction workers. In addition, for the implementation of this method requires expensive special drill bit.

The implementation of the invention

Figures 1 and 1A shows a perspective view of the retainer disc 4 of the fastening element 1 according to the invention mounted on the presser disk cover 11, which serves as the receiver for the insulating material. As seen in the drawings, the lower side of the clamping disk 4, facing in the direction of installation, are milling device 9 for cutting milling insulating plate 2, and the notches 10, through which cut milling mate the ial group can pass through that is, the notches in the clamping disk 4 is made through. Milling device 9 is made, usually in the form of cutting edges located directly underneath the grooves 10 for the most effective removal cut milling insulating material. However, it is also possible, in which the notches 10 and milling device 9 is located at a distance from each other. While milling device 9 can be made in the form of protruding walls or areas with rough surface. Instead of the form shown in the form of slits or slots of the recess 10 may have a round or oval shape larger, especially when they are spatially removed from the milling device 9. Serving as receiver cover 11 may be either rigidly connected with the clamping disk 4, for example, by producing at the same time with him, or can Rethimno to connect with him using clamping fixtures (not shown)so that its height position relative to the clamping disk 4 can be adjusted. In addition, the cover 11 is made a hole 13 for the passage davinciaudio device 14. Additionally, the cover 11 is equipped at its lower edge a circumferential cutting edge 22, which facilitates the cutting in the insulating plate 2. Further, the cover 11 forms one or more cameras 12, in which exp is connected by milling insulating material. As particularly well seen in figure 1, the spacer element 6 head 7 spacer element is inserted into a deep notch in the tip of the clamping disk 4, so that it can be deeply embedded in the insulating material. In this way preventing the formation of thermal bridges.

In figure 2, the fastening element 1 according to the invention shown in an installed condition. The presser disc 4 buried in the insulating plate 2, and the dowel sleeve 5 in the spacer region 8 is fixed in the groove 16, that is, in the supporting structure 3, by means of the spacer element 6 is screwed with davinciaudio device 14. It is clear that the cut milling devices 9 of insulating material passed through the notches 10 in the cover 11, where he continues to perform the function of isolation from the outside. In the end position, the cover 11 is flush with the outer surface of the insulating plate 2 in order not to create irregularities in the plaster. Now, after removing davinciaudio device thin plates forming the opening 13 of the cover 11 can again be closed, so that the cover no holes. Due to this, preventing the formation of depressions in the layer of plaster.

On 3 and 4, the fastening element 1 according to the invention shown in position to start the installation. Pre-drilled groove 16, passing through isolation the th plate 2 in the supporting structure 3, and dowel sleeve 5 and the spacer element 6 is already entered in the groove 16. The presser disc 4 adjacent to the outer surface of the insulating plate 2. Dowel sleeve 5 is introduced into the groove 16, and the spacer element 6 is inserted in the dowel sleeve, not reaching the spacer zone 8. Davinciaudio device 14, which covers all known screw-in tools (such as drill, drive tip, and so on), is engaged with the mating slot in the spacer cylinder 7, so that this phase feed spacer element 6 for his burial. When this insulating plate 2 milled due to the penetration of the milling device 9 on the lower side of the clamping disk 4, and simultaneously passing through the notches 10 of the clamping disk 4 cut milling insulating material is collected in the corresponding receiving device.

Rotational movement davinciaudio device 14 is transmitted to the presser disk 4, as a rule, through a hexagon socket 21 at the tip of the clamping disk 4, corresponding in shape to the head 7 of the spacer element (of course, depending on the execution of the head 7 spacer element socket 21 can have other forms). In the exemplary embodiment according to figure 3 the receiving device is formed by a cover 11. In the example in figure 4 the receiving device 17 is formed by a cover 11 and dopolnitelnaja 15 in the form of a bag. A possible variant, which is shown in figure 4, the cover 11 is missing and there is only a bag or other adequate type of housing 15, such as a closed top cap. With this bag or nozzles cut milling insulating material can be collected and sent for recycling environmentally friendly way.

Next, as shown in figure 2, 3 and 4, clamping the disk 4 and the dowel sleeve 5 is made in two separate parts. Figure 4 position 19 marked the wedge-shaped protrusions on the end tip of the clamping disk interacting with the corresponding socket 20 on the upper end of the dowel sleeve 5, and a socket 20 formed end flange dowel sleeve and located slightly below the district ledge. While the district ledge is designed so that when installed, the fastening element 1 to the clamping disk exert pressure, wedge-shaped protrusions 19 may slip over the district the guide slot 20 and exit, so that the clamping disk 4 and dowel sleeve 5 can be displaced along the axis relative to each other. However, the connection dowel sleeve 5 and the clamping disk 4 can also be made rigid with the specified place of disconnection, or they may be connected by gluing. In the aspect of reducing the length of the fastening element in an alternative embodiment, m is can be provided by the shear zone between the clamping disk 4 and dowel sleeve 5 (or only in the dowel sleeve 5).

Figure 5 fastening element 1 according to the invention is shown in an alternative example implementation in the final installation position. Cover 11 with a circumferential cutting edge 22 is slightly extends over the edge of the clamping disk 4 (this can be provided already during manufacture or provided after him using the above-mentioned locking fasteners), which facilitates cutting into the insulation material. On the upper side of the cover 11 is a layer 18 of insulating material. Compared to the cover 11, it creates a more uniform outer surface that is more convenient for applying a layer of plaster. In this example, the complete volume of the receiving device to cut milling insulating material is less than the previous version.
