For insulation purposes, sections are cut off by a knife or similar on site from the unwound clamping felt roll, wherein a length of the clamping felt rolls corresponds to a clear width between the rafters and a predetermined oversize. These clamping felt sections are accordingly inserted between the rafters under pressure which builds up a reset spring force within the clamping felt so that the clamping felt is firmly supported between the rafters. Due to a considerable thickness of the rafters a large amount of damping material can be arranged between the rafters due to a considerable thickness of the rafters when providing between rafters insulation which naturally increases the insulation effect.
  • the subsequently described invention does not relate to external insulation of buildings but to an internal insulation of buildings wherein the insulation material is arranged from an inside under the inward oriented faces of the rafters (so called under rafter insulation).

  • FIG. 37 components in FIG. 37 which are more or less identical or functionally equivalent to components in other embodiments are provided with the same reference numerals. It starts with the rafter element 2 on which for example a pedestal element 22 is attached which certainly can also alternatively configured according to the other embodiments which also applied for the pedestal 34 and the base member 28 and other components. It is evident in the embodimetn according to FIG. 37 that the head piece 78 is offset relative to the preceding embodiments relative to the insert 31, thus in the form of a screw 60 similar to the embodiment according to FIG. 12 as evident in particualr from FIGs. 39 and 40 by the same token the head piece 78 is configured as a universal receiving element, this means it can alternatively receive a sheet metal profile bar 32 according to the illustratons of FIGs. 28 and 41 or for the same component alterantively also a wooden slat 10 as evident from FIG. 37 , right illustration top and FIG. 42 .
  • the head piece 78 includes a stop element on a right side which stop element is configured as plural upward protruding stop bars 220 with an engagement groove 80 arranged behind them.
  • On the opposite side horizontally protruding engagement members 222 are provided which protrude in outward direction beyond the block shaped configuration of the head piece 78 as evident from FIG. 41 and which facilitate snap locking the sheet metal profile bar 32.
  • the sheet metal profile bar 32 with ist two lateral C- arms reaches over the engagement members 222 and the stop members 220 and reaches behind them with their inward protruding extensions or arms 82 so that the bar 32 can be snap locked in a simple manner onto the head piece 78.
  • the stop members 220 and/or the engagement members 222 respectively can also be configured as a continuous bar when required.
  • the same head bar 78 can also be used for receiving a wooden slat 10 as evident from FIG. 37 , top right illustration and FIG. 42 .
  • plural recesses or openings 224 FIG. 39 ) on a top portion of the head piece 78, which facilitates a screw attachment of the wooden bar 10 with typical wood screws 51, wherein in this embodiment two attachment screws 51 can be provided in an exemplary manner.
  • the recesses 224 can be evenly distributed in the illustrated embodiment, in particular in rows that are oriented perpendicular to each other and furthermore respectively parallel to each other so that a plurality of recesses 224 is provided and a quick and simple assembly of the wooden slats 10 can be performed with the screws 51.
  • the stop members 220 are thus used as stop elements for a simple application of the wooden bar. From FIGs. 39 and 40 a support of the screw 60 is evident that is offset in outward direction relative to the head piece 78. This support is advantageously similar to the embodiment according to FIG. 12 due to an annular bead 228 that is arranged from the upper screw head 226 offset in downward direction and thus axially fixateable relative to the head piece 78 but rotateable. This in turn facilitates the assembly since the screw that is inserted overhead through snap locking cannot be lost anymore but can be rotated for adjusting the head piece 78 also for a received profile bar 32 or slat 10 relative to the pedestal 34.
  • an outward protruding lug 32 is advantageously provided at the head piece 78 in which lug the screw 60 is received. Also this only serves as an example, certainly also a bar shaped protrusion or similar can be used or configured. Last not least the head piece 78 as evident from FIGs. 39 and 40 can be provided on one side, thus advantageously the side opposite to the lug 128 or the screw 160 with a protrusion, thus in particular configured as a protruding bar 230 which facilitates manual handling of the head piece during assembly. Certainly this bar 230 is only provided when required, but advantageous in the context of the invention. This also applies for the configuration of a total of four stop members 220 for the support bar or for outward protruding horizontal bar shaped engagement members 222. Where required these engagement members can be configured as a bar or with more or fewer separate engagement members.
  • the head piece 78 is also configured as a plastic component, in particular provided as an injection molded component.
  • the subsequent steps 21 and 22 relate to mounting the attachment device at the rafter or similar:
