Definitions

  • the invention relates to a method for producing a heat-insulating and at the same time covering roof structure according to the generic term of Claim 1, a roof structure according to the preamble of the claim 5 or 12 and an anchor element for use with a Roof structure.
  • a roof structure and a method were therefore already described in DE 197 57 254 described for its manufacture, at the point loads thereby be avoided that between the anchor elements of the to be created Roof structure and the existing roof introduced a binder the roof structure is flat in several predetermined places is attached to the existing roof.
  • the object of the present invention is a method and specify a roof structure in which the anchor elements slip with sufficient certainty during the curing process of the binder is avoided.
  • a key concept of the present invention is the anchor elements to be temporarily fixed at the position intended for them. According to one aspect of the present invention, this is done by that the anchor elements with a fast curing fixing substance be fixed to the existing roof so that it slips is prevented with sufficient certainty. Guaranteed the fixing substance itself does not have sufficient tensile strength to achieve a Attachment of the entire roof structure with sufficient reliability to guarantee. Rather, this requires that special binders be used Fixing the anchor elements on the existing roof between the anchor elements and the existing roof is introduced, so that a permanent and sufficiently tensile connection via one or more Form extensive areas between the anchor element and the roof can.
  • the fixing substance is made via recesses introduced in the anchor elements, such that the anchor elements be pre-fixed in the area of these recesses.
  • This has the fixation substance on the one hand sufficient attack surface on the respective Anchor element; on the other hand, the amount of the fixative introduced be well controlled based on their level in the recess.
  • a comparatively small amount such as walnut size, be sufficient for fastening an anchor element.
  • not one, but two recesses are provided. A higher number of recesses is also conceivable, but then the effort to fix an anchor element increases accordingly.
  • the binder on the End face of the anchor elements introduced and overflows in the anchor elements provided longitudinal grooves in the area between the anchor element and roof 1.
  • the speed and depth of break-in depend on the surface and slope of the roof. With most roof shapes the binder can run in over the entire length of the anchor elements and usually also emerges at the opposite end. Hereby can be checked that the binder is completely between anchor elements and roof has broken in.
  • the binder can also be introduced laterally and runs at least partially in the area between the anchor element and roof one.
  • the inlet depth is also of the shape and depending on the surface of the roof.
  • the binder runs on corrugated roofs following the waveform under the anchor elements pre-fixed in the wave valley on.
  • the binder is preferred after pre-fixing introduced around the entire anchor element along its circumference.
  • Anchor elements are used, each with at least one recess for introducing a fixing substance, such as assembly foam.
  • the recess is designed so that the anchor elements after insertion the fixing substance on the roof are pre-fixed. Training the anchor elements with such recesses thus provides a reliable and at the same time an inexpensive solution to the above Problem.
  • the fixing substance is only used to pre-fix the anchor elements serves and the actual attachment takes place via binders, should Improvement of the gluing with the existing roof the anchor element have a structured adhesive surface. This will make it effective of the binder reinforced. At the same time, even if the Assembly foam for the binders introduced in the next step sufficient adhesive surface created.
  • the anchor element is included an upper side for fastening the roof support two end faces as well two flanks and in the area between the flanks with an underside provided, one or more longitudinal grooves in the area of the bottom are provided for the introduction of binders and / or improvement the adhesive properties are formed when the binder is introduced.
  • the longitudinal grooves guide the end face, especially when the roof is sloping Binder in the area between the roof and the underside of the anchor element. If the longitudinal grooves are continuous, with appropriate The surface and slope of the roof also adhere to the binder emerge again from the opposite end of the anchor element, so that a wetting of the entire longitudinal extent of the underside is ensured and can be checked.
  • the anchor elements have an approximately semicircular cross-section, with a longitudinal groove in Vertex and two further longitudinal grooves by 15 ° to 40 °, preferably about 25 °, are spaced from the apex.
  • This arrangement allows a particularly favorable distribution of the binders.
  • the binder be effective in the area of the underside of the anchor elements. In the side Ascending binder area improves the extraction values Wind suction load only insignificant.
  • the problem is solved solved the sliding of the anchor elements in that several Anchor elements are connected together to form an anchor chain.
  • This Design may be sufficient to fix an anchor element to the to hold the entire anchor chain.
  • the anchor chain can also be used without fixation an anchor element itself temporarily on one or more of your connecting elements be fixed.
  • Frictional forces of the anchor chain on the ridge and the anchor elements on both sides of the ridge prevent the anchor chain from slipping.
  • these are the connecting elements rigid, for example designed as a punch.
  • the connecting elements are flexible and tensile, for example as a wire or wire rope. While according to the last alternative embodiment, slipping because of the tensile strength of the connecting elements is excluded only in the direction of pull forces can also act against rigid connecting elements intercepted in the direction of pull or laterally to the anchor chain and slipped of a single anchor element can be prevented.
  • Another aspect of the present invention is one for manufacturing of the above-described roof structure formed anchor element.
  • On such anchor element can be sold as a separate component and by Roofers are sourced, who in turn use a roof structure erect the anchor elements of the invention.
  • the 1 is an embodiment of an anchor element according to the invention 14 shown in cross-sectional view.
  • the anchor element 14 is on one existing roof 11, here a corrugated asbestos roof attached by binder 17.
  • the binder 17 is a in a preferred embodiment Polyurethane-based specially developed adhesive with which high Have extract values guaranteed.
  • the anchor element 14 is in the middle plane halved log with two faces 44, 45 (Fig. 4).
  • the between the End faces 44, 45 lying flat flat side defines an upper side 34.
  • Die round lateral surface is formed by two flanks 31, 32 and one in between arranged underside 35 defined.
  • Flanks 31, 32 and bottom 35 go in the cross-sectional shape described here continuously into one another, with the flanks 31, 32 approximately over an angular range of 45 ° and the bottom 35 extend over an angular range of 90 °.
  • the underside 35 of the anchor elements 14 is designed as an adhesive surface 18.
  • the anchor elements inserted in troughs 16 of the existing roof 11 14 are also from the adhesive surface 18 via binder 17 glued to the existing roof 11.
  • the anchor element 14 preferably has between the upper side 34 and the lower side 35 two each arranged in the end regions of the anchor element 14 recesses formed as through holes.
  • the Through bores 21, 22 are centered with respect to the flanks 31, 32 arranged such that the through holes 21, 22 each at the apex 36 of the bottom 35 ends.
  • the through hole 21 for the purpose of pre-fixing the anchor element 14 the existing roof 11 partially with fixing substance 33, which here conventional assembly foam can be filled.
