Definitions

  • the present invention relates to a heat-insulating, cuboid component for preventing thermal bridges in walls, e.g. from masonry.
  • a thermal bridge is a local area through which increased heat can flow away within a structure that is well insulated per se.
  • Such weak points have to be avoided by constructive measures.
  • Recommendation SIA 180/1 is accordingly required to avoid thermal bridges or that these may have to be compensated for by special measures such as increased thermal insulation and careful connection details (see Art. 4.5 of recommendation SIA 180/1).
  • the mean vertical stresses acting in the base of the wall can be up to 1.2 N / mm2 from the weight of the possibly multi-storey structure. Furthermore, it must be ensured that horizontally acting forces, for example due to ground vibrations, wind, etc., can be reliably transmitted.
  • the purpose of the present invention is now to provide a component for preventing thermal bridges which can be used without having to accept the structural and financial disadvantages described above.
  • the component is characterized by a core of preferably closed-cell thermal insulation material and a skeleton which penetrates the core and partially covers it to absorb the forces acting in the wall.
  • the skeleton is constructed in such a way that only a minimal amount of heat, which is not in relation to the volume of the component, can flow away due to its mechanically highly stressable but poorly heat-insulating material is more important.
  • the thermal insulation material which is protected from stress by the skeleton, can thus form an effective barrier to the heat flow.
  • the preferred exemplary embodiment has a band-shaped web that runs back and forth through the core in a zigzag fashion between opposite longitudinal sides of the element.
  • an upper and a lower flange are also provided, which run perpendicular to the web and together with the latter in cross-section the profile of a double-T beam exhibit.
  • Upper and lower chords cover the core surfaces in some areas. This means that it is largely protected against mechanical damage during storage and transport.
  • the skeleton can also have several ribbon-shaped, e.g. have webs which are interlaced or formed only in sections and pass through the core.
  • at least one of the webs and / or web sections is then provided with an upper and / or a lower flange, the upper and lower flange covering regions of mutually opposite surfaces of the core.
  • the skeleton is made of a non-brittle mineral-based material.
  • a mineral fiber composite material is preferably used.
  • such a skeleton has a comparatively large heat transfer, it will Improved load-bearing behavior for highly stressed components such as supports or balcony connections can be decisive.
  • the component according to the invention enables a flawless technical solution with simple means and low costs. It can be used as a load-bearing and heat-insulating component e.g. be bricked up on the basement ceiling as the first layer of the rising masonry. As a result, it lies within the structural strength of the underlay, so that there is no change of material when the interior walls are plastered.
  • the use of the component is by no means limited to the base of the wall, although its advantages are particularly effective there. It can be used wherever excessive heat flow should not only be prevented across the wall, but mainly in the plane of the wall or the component itself.
  • the elements can be bricked in lengths that correspond to the multiple of the brick format as the first layer.
  • recesses are arranged in the cover layers, into which the masonry mortar can penetrate, so that a full contact is guaranteed over the entire length of the element.
  • the same recesses also form an interlocking with the ceiling and masonry.
  • the cross-section and length of the element are matched to the usual brick formats. This enables economical production as standard elements. Furthermore, the elements can easily be cut to the desired length on site. When using a closed-cell thermal insulation material, the open prevents moisture.
  • FIGS. 2 and 3 show a view of the component 1 according to the invention (FIG. 2) and a view the same component in which the core 11 has been removed from preferably closed-cell thermal insulation material (Fig. 3).
  • Upper and lower chords 16, 17 serve to ensure that no excessive pressures occur on the connecting surfaces of the masonry that are adjacent to the component.
  • the web is of course designed according to the masonry loads to be removed, but as narrow as possible so that the amount of heat flowing through it can be kept to a minimum.
  • the strips are on the surfaces covered by the upper and lower chord of the core and are integrally formed with the upper and lower chord. This creates areas on all sides of the skeleton (apart from the ends of the component) in which the surfaces of the core are not covered. These areas should not be unnecessarily reduced by over-wide top and bottom belts.
  • the web 13 running back and forth between the longitudinal sides of the component has sections 18 which run parallel to the latter in the region near these longitudinal sides. This makes it possible that the upper and lower chord can always protrude from both sides of the web and thus the connection between the upper and lower chord is essentially only under pressure and thus no impermissible bending moments are generated in the web itself. Since the resultant of the wall load often runs eccentrically in the wall, the zigzag-shaped web ensures that the wall load is properly absorbed.
  • Figures 2 and 3 has only one web, it is readily conceivable that several webs, which are interlaced, for example, in a regular sequence, are provided for special applications. Also can only go out in sections formed webs are provided. It may make sense not to provide all the webs or sections with an upper and / or lower flange, since the same conditions do not exist in the various connecting surfaces or the free areas should not become too small for the interlocking with the masonry.
  • the core of thermal insulation material is kept uncovered by the skeleton over the entire area of a long side of the element.
  • This can also be achieved retrospectively in the case of an existing component in that the longitudinal side mentioned is covered with a strip of thermal insulation material, the corresponding strips 17 (FIG. 2) then also having to be covered by the upper and lower flange.
  • the thickness of the strip is preferably 1 cm.
