Definitions
- the present invention relates to a heat-insulating, load-bearing component
- 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 must be avoided through constructive measures.
- existing standards e.g. Recommendation SIA 180/1, it is accordingly required that thermal bridges be avoided 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 / mm 2 from the weight of the possibly multi-storey structure. It must also be ensured that horizontally acting forces, for example due to ground vibrations, wind, etc., can also be reliably transmitted.
- DE-A-30 35 931 discloses a heat-insulated component that can be installed as a wall element. However, this could only be loaded centrically and is therefore not suitable for absorbing the wall forces that occur in load-bearing masonry.
- the purpose of the present invention is now to provide a device for preventing thermal bridges which can be used without having to accept the constructional and financial disadvantages described above.
- the component has the features of claim 1.
- 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 also protected against mechanical damage during storage and transport largely protected.
- the skeleton can also have several band-shaped, in regular order e.g. have webs which are interleaved or formed only in sections and pass through the core.
- at least one or 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.
- the component according to the invention enables a perfect 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 sub-floor, 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 absorption of moisture is prevented.
- Figure 1 shows a cross section through part of a building, 1 the component according to the invention, 2 a basement ceiling, 3 a basement wall, 4 the surrounding soil, 5 the thermal insulation layer on the ceiling, 6 the floor shell, 7 the outer shell and 8 the inner shell of the rising masonry.
- a heat insulation layer 9 is located between the outer and inner shells 7, 8.
- the component according to the invention used to interrupt the otherwise existing thermal bridge.
- the dashed section of the arrows makes it clear at which point the heat flow from the room 10 would be significantly increased without the use of the component 1.
- FIGS. 2 and 3 show a view of the component 1 according to the invention (FIG. 2) or a view of the same component in which the core 11 has been removed from preferably closed-cell thermal insulation material (FIG. 3).
- the upper and lower chords 16, 17 serve to ensure that no excessive pressures occur on the connecting surfaces of the masonry that are in contact with 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 required width of the upper or lower flange is generally approximately 50% of the height of the associated web; however, it must also be adapted to the mechanical properties of the adjoining element.
- the strips are located on the surfaces of the core covered by the upper and lower chord and are formed in one piece 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.
- Figures 2 and 3 has only one web, it is easily conceivable that for special applications several webs, e.g. are intertwined in a regular sequence. It is also possible to provide webs formed only in sections. 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 be too small for forming the interlocking with the masonry.
- the core of thermal insulation material is kept uncovered by the skeleton over the entire surface 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.
