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.
