Method for fastening of elastomeric or insulating materials between two structural components
FIELD OF THE INVENTION 
     The invention relates to a method for fastening of elastomeric or insulating materials, for instance an elastic mat, between two structural components whereby one of the structural components is produced on site after the insertion of the elastomeric or insulating materials. 
     THE RELATED ART 
     In order to fasten elastomeric or insulating materials between two structural components, up to now sections of rigid synthetic material or metal have been used. However, these materials create sound conductors between the two structural components. 
     It is the object of the invention to create a fastening system which insures a secure fastening of the elastomeric or insulating material and at the same time has a decoupling effect on vibrations which may occur. 
     SUMMARY OF THE INVENTION 
     The solution to the problem consist in a method of the above-mentioned kind, whereby the upper shank of a Z-shaped elastomer section formed by two vertical shanks and one horizontal web is fastened by nails or the like to the already finished structural component, while the lower shank of the elastomer section reaches over the elastomeric or insulating materials and whereby then a cover element is fitted over the head of each nail or the like and after that an elastic cord is fitted on top of the elastomer section. Finally the second structural component is produced, whereby the elastomeric or insulating material, the elastomer section, the cover element and the elastic cord serve as a disposable form. The cover element prevents contact between the still fluid concrete and the nails or the like during the production of the second structural component, since at this contact points sound conductors can form. 
     By the method of the invention the transmission of vibrations from one structural component to another is completely eliminated. Furthermore, an elastic sealing of the gap between the two structural components results, so that horizontal as well as vertical motions of the two components can be elastically taken up. 
     In an embodiment of the invention the cover element is designed like a cap surrounding the washer provided under the head of each nail or the like. 
     In a further embodiment of the invention the used elastomer section has at its upper shank a horizontal flange,which together with the horizontal web forms a chamber for receiving the cover element, whereby the cover element is U-shaped and arranged in such a manner that in the mounted state the webs of the U-section face the elastomer section. 
     According to a further feature of the invention, the horizontal flange as well as the horizontal web are each provided with a ridge reaching behind the cover element. 
     In a particularly simple embodiment of the method of the invention the used elastomer section has at its upper shank a horizontal flange whereupon a cover element is formed. 
     Suitably, on the upper shank of the elastomer section an elastic cord is formed.

     DETAILED DESCRIPTION 
     In the embodiment example shown in FIG. 1 the upper vertical shank 1.o of a Z-shaped elastomer section 1 consisting of two vertical shanks 1.o and 1.u and horizontal web 1.m is fastened by nails 2 or the like to the finished structural component 3, while the lower shank 1.u of the elastomer section 1 reaches over an elastic mat 4. The elastomer profile 1 has on its upper shank 1.O a horizontal flange 1.F, which together with the horizontal web 1.m of the elastomer section 1 forms a chamber for receiving the cover element 5. On the upper shank 1.o of the elastomer section 1, respectively on the flange 1.F, an elastic cord 6 is fitted, which extends up to the surface of the structural component 3. The second structural component 7 is produced on site by using the elastic mat 4 , the elastomer section 1, the cover element 5 and the elastic cord 6 as a disposable form. 
     In FIG. 2 an embodiment example basically corresponding to FIG. 1, wherein the flange 1.F and the horizontal web 1.m of the elastomer section 1 each have a ridge 8 which reaches behind the cover element 5. 
     In the embodiment example shown in FIG. 3 on the upper shank 1.o of the elastomer section 1 an elastic cord 6.1 is formed. 
     FIG. 4 shows an embodiment example wherein on the flange 1.F of the elastomer section 1 a cover element 5.1 is formed. 
     The embodiment example represented in FIG. 5 shows a fastening system wherein the cover element 5.2 is designed like a cap surrounding the washer 9 provided under each nail 2.
