Abstract
ABSTRACT
A thermal insulation (construction) element for build-ings including projecting wall portions, especially balcony panels. This element comprises an insulation body and reinforcing elements passed through the insu-lation body. The reinforcing elements pass through the insulation body in a vertical position; they serve to bear vertical forces, whereby additional abutmenets are not necessary. The vertical portion of each rein-forcing element has its end joined to horizontally extending portions projecting into a building part on the one hand and into the projecting wall portion on the other hand.

Description
B~
The present invention relates to a construction element for thermal insulation in buildings, especially in pro-jecting wall portions, comprising an elongate insulationbody formed of a thermally insulating material, and metallic reinforcing elements protruding laterally for anchoring purposes, said construction element being formed as a prefabricated part.
A construction element of this type is known from German Patent 30 05 571. This construction element includes a thrust bearing block or abutment to bear horizontal forces.
The reinforcing elements extend in part obliquely through the insulation body. The reinforcing elements are adapted to bear also vertical forces. However, construction ele-ments of this kind are unsuited when no momentum forces, but only vertical forces are to be taken up. This applies, for example, when the projecting wall portion is supported by pillars at the side remote from the building. Likewise, substantially vertical forces are involved in balcony panels rested on three sides or two sides. Even if only vertical forces are present~the conventional construction element requires a thrust bearing block or abutment, be-cause horizontal forces occur even in the case of onlyvertical loading due to the oblique extension of the reinforcing elements interiorly of the construction ele-ment, which horizontal forces must be taken up by the abutment. In multi-sidedly supported balcony panels, another drawback resides in that the transverse rods must bear different tensile forces owing to temperature variations within the balcony (panel). When the balcony ~panel) shrinks, additional tensile forces are produced, whereby the balcony (panel) is slightly raised. When the balcony (panel) expands, compressive forces result under which the balcony (panel) is slightly lowered. Further, in the case of balconies (balcony panels) supported on two sides, their length is limited by the connection through the construction element, which acts in the manner of a clamping means. In a wall portion being supported on pillars at the side opposite to the buildiny, the elastic deflection thereof in the a~utments results in extra compressive forces in addition to the mathematically determinable compressive force, which extra compressive forces cannot be investigated or determined mathematically.
It is therefore the object of the present invention to provide a construction element for thermal insulation in buildings, which does not require any abutments and in which temperature variations do not produce any additional stress in the reinforcing elements.
~n the construction element as outlined above, according to the invention this object is solved in that the rein forcing elements extend vertically interiorly of the insulation element or body.
Below, the invention is described in greater detail by referring to exemplary embodiments illustrated in the Figures, wherein: -Figure 1 is a vertical cross-sectional view of a first embodiment of a construction element in the installed state thereof;
Figure 2 is a vertical cross-sectional view of a second embodiment of a construction element; and Figure 3 is a vertical cross-sectional view of a third embodiment of a construction element.
Figure 1 illustrates portions of a building, namely, for example, a building wall 1, a concrete ceiling 2 and a projecting building portion also formed of concrete, such ~ r~
as e.g. a balcony panel 3. Positioned between these components in well~known manner is a thermally insulating prefabricated construction element including an insulation body 4. The longitudinal direction of this insulation body 4 extends perpendicular to the plane of the section.
Disposed within this insulation body 4 are vertical steel rods or bars 5, arranged with a predetermined spacing from each other in the longitudinal direction and acting to take up or bear the vertical forces. Owing to this arrange-ment of the steel rods 5 serving as reinforcing elements, no horizontal forces are produced when the vertical forces are absorbed, such that thrust bearing blocks or abutments are not necessary. Preferably, the projecting (cantilever) concrete panel 3 is mounted to be suspended. In this manner, displacements caused by temperature variations can be compensated in a particularly efficient manner.
The ends of the steel rods 5 have joined thereto hori-xontally extending cantilever beams 6 and 7 formed of steel. The cantilever beam 6 extends into the concrete ceiling 2, while the cantilever beam 7 projects into the balcony panel 3. These cantilever beams act to bear the cantilever forces from the concrete ceiling 2 and the balcony panel 3, respectively. The vertical free length of the steel rod 5 between the cantilever beams 6 and 7, and the kind of attachment to the cantilever beams are responsible for the maximum flexibility of the balcony.
Figures 2 and 3 illustrate construction elements which can be produced in a particularly efficient manner. Here, the reinforcing element comprises a bent (angled) steel rod 8. This steel rod has its center portion passing vertically through the insulation body 4' or 4", respectively, while its two end portions are angled so as to extend in the horizontal direction. In this structure, one end portion extends into the concrete '` ' ~ 2 ~3~ ~
ceiling of the building, and the other end portion eY.tends into the projecting balcony panel. ~he insulation body 4' of Figure 2 includes in the area o~ the horizontal portions of the steel rod 8, depressions or recesses 9 and 10 which may be filled out with concrete. Then, the steel rod 8 is securely embedded in concrete in the area of the upper and lower bents. There is left a vertically extending center portion in which the steel rod passes freely through the insulation body 4' so as to be flexible or movable. In the construction element shown in Figure 2, the recesses 9 and 10 may be filled out with concrete before the construction element is transported to the construction site. Another alternative is to transport the insulaticn elements with the steel rods passing there-through to the construction site, and to fill out the recesses 9 and 10 at the site when the adjoining components are cast from concrete.
The insulation body 4" according to Figure 3 does not show the discrete recesses in the area of the horizontal portions of the steel rods 8, but is rather formed in a corresponding manner throughout its length. Thus, it comprises an upper and a lower vertical section which are displaced relative to each other in the horizontal direction. The center section joins the upper and lower sections such that i~ upper and lower edges are inclined.
The steel rod 8 passes through the insulation body 4" with its vertically extending part only, such that the bents and the horizontally e~tending portions are left e~posed.
These portions are thereafter embedded in concrete during concrete casting o~ the building ceiling or of the balcony panel, respectively. In this way, a continuous cantilever bed is each formed, both at the side of the ceiling and at the side of the balcony.
