Description
The present invention relates to a construction element for thermal insulation in buildings, especially for projecting external structures, comprising an elongated insulation body formed of a thermally insulating material, elongated metallic reinforcing elements extending sub-stantially transversely of the insulation body and protruding laterally beyond said insulation body, and compression elements for force transmission between the projecting structure and the remainder of the building structures.
In the case of buildings having projecting wall structures, for example, balconies, loggias, external landings or stages, house entrance panels or the like, the problem of an undesirable heat dissipation arises, because projecting wall structures of this ~ind are generally joined to a corresponding intermediate ceiling (false floor) in the building and constitute the outside extension of such intermediate ceiling. Thus, the projecting panels or wall structures ~orm cold bridges to the outside, which, on the one hand, involve thermal losses and, on the other hand, may even cause damage to the construction.
For this reason, construction elements are provided between the projecting structures and the building, which elements provide for thermal insulation on the one hand and satisfactory load transmission on the other hand. DE-AS (published German patent application) 30 05 571 shows to be known a construction element of this type which is formed as a prefabricated part and includes at least one compression element integrated into the insulation body as a connecting core element and having dimensions adapted to the cross-section of the insulation body. In this instance, the insulation i~
body which has reinforcing elements inserted or cast thereinto, is of integral (one-piece) structure. Inte-gral casting of the reinforcing rods involves the draw-bac~ that the insulation element t including the rein-forcing elements must be transported as an integral unit from the place of manufacture to the respective con-struction site. Further, each element must be manufactured specifically to comply with the respective requirements.
io When the reinforcing rods are inserted into the insul-ation body, it is difficult to consistently achieve the desired alignment or orientation of the reinforcing rods. In particular, such insertion is problematic when the rods have their ends bent in a hook-shaped confi-guration, and when the rods extend through the insulationbody obliquely or at an angle, while being position~d horizon~ally for the rest, such that the rods have at least two kinks.
It is therefore the object of the present invention to provide a construction element for thermal insulation between projecting external parts or structures (of a building) and the building per se, wherein the rein-forcing elements - irrespective of their configuration -26 are joined to the insulation body in easy manner, and such joining may be effected directly at the site where the construction element is used, or at the manufacturer's place. Also, the reinforcing elements should be adapted to be aligned or oriented as exactly as possible with respect to the insulation body.
In the construction element as outlined at the be-ginning, in accordance with the invention this object is solved in that the insulation body comprises an upper portion and a lower portion, with the reinforcing elements being positioned within the upper portion and the compression elements being disposed within the lower portion, and that upper portion and lower portion ~7J~
are formed so as to be adapted to be fitted together.
In this structure, the reinforcing rods, extending through the insulation body both horizontally and ob-liquely, are secured to the upper portion and constitute a reinforcing basket or cage. Dimensionally, these rods orient themselves by the upper edge of the insulation body. In particular, the horizontal reinforcing rods must be disposed in an upper position with a fixed spacing from the surface of the balcony or ceiling. The insulation body therefore may be well aligned or oriented on the upper side and mounted to the rein-forcement of the ceiling or balcony. As the compressionel~ments are arranged within the lower portion so as to be positioned in the region of the compression zone, optimum transmission of forces between the projecting external structure and the building is ensured.
Preferably, the upper portion includes in its upper region horizontal grooves for receiving the reinforcing elements which pass horizontally through the insulation body, and it includes studs for the fixing of rein-forcing rods which pass through the insulation bodyat an angle to the horizontal; and the lower portion is provided with recesses for receiving the studs with frictional engagement. In this structure, the lower portion is preferably farmed with so small a wall thickness in the area of the recesses that, when the studs are inserted, the lower portion is adapted to be broken up by the obliquely extending reinforcing elements retained by the studs up to the depth of penetration of these reinforcing elements.
Below, the invention is described in greater detail by referring to exemplary embodiments illustrated in the drawing, wherein:
4a Figure 1 is a sectional view of the insulation body normal to its longitudinal direction, with reinforcing elements inserted;
Figure 2a is a plan view showing a recess formed in the lower portion of the insulation body;
Figure 2b is a plan view showing another recess of a different configuration, formed in the lower portion of the insulation body;
Figure 3 is a view of the longitudinal side of a second embodiment of the upper portion and a plan view of the corresponding section of the lower portion;
Figure 4 is a sectional view of another embodiment of the insulation body, no~mal to its longitudinal direction;
Figure 5 is a .sectional view of a further embodiment of the insulation body, normal to its longitudinal direction; and Figure 6 shows a device for mounting the lower portion.
The insulation body shown in Figure 1 is positioned, for example, between the floor panel of a balcony and an intermediate ceiling of a building. Preferably, the insulation body is disposed in the plane of the insulating plaster of the respective building wall. The insulatio~
body is contemplated to minimize the contact between the floor panel of the balcony on the one hand, and the intermediate ceiling on the other hand, thereby to provide for optimum heat insulation between these two structures.
~a2~7~
The insulation body comprises a lower portion 1 and an upper portion 2. The lower portion 1 is provided with recesses 3 arranged one behind the other(spaced from each other) in the longitudinal direction. The upper portion 2 includes studs or projections 4 opposing the recesses 3 of the lower portion 1. When upper and lower portion are jointed together, the studs 4 are fully receivedwithin the recesses.
Intermediate the studs 4, the lower side of the upper portion 2 has formed therein grooves 5 into which horizontally extending reinforcing rods 6 are pl~ced.
These reinforcing rods 6 act to absorb horizontal tensile forces. The lower edge of each stud 4 is cut under an angle to the horizontal. Reinforcing rods 7 passing obliquely through the insulation body are attached to this lower edge. Preferably, this lower side of each stud 4 is also provided with grooves ~ extending in parallel with the lower edge, with the reinforcing rods 7 being placed into these grooves and secured therein.
The reinforcing rods 7 also serve to absorb vertical forces. The reinforcing rods 6 or 7 may be secured within the grooves 5 or 8, respectively, by means of an adhesive or by means of clamps or clips fixed within the grooves.
The structure shown in Figure 1 is assembled in such a way that the reinforcing rods 6 and 7 are first inserted into the corresponding grooves 6 or 7 or secured to the associated surfaces. Then, the upper portion 2 and the lower portion 1 of the insulation body are joined togetherOIn this operation, the studs 4 are pressed into the respective recesses 3 to full length.
Hereby, the obliquely extending reinforcing rods 7 break up (cut through) the walls of the recesses 3 to a depth equal to the depth of penetration of these rods. The reinforcing rods 7 are positioned such that they come to meet the recesses in positions where the walls of the recesses are of minimum thickness. Therefore, the rein-forcing rods 7 produce only vertically extending slot-like cuts. Figures 2a and 2b show the cross-sectional configurations of two different recesses. In the hexa-gonal recess according to Figure 2a, the two positions where the wall of the lower portion has minimum thick-ness, are defined without any further measure. The reinforcing rods 7 are driven through the lower portion 1 between these two positions. Figure 2b illustrates a rectangular recess 3. In order to provide two defined positions of minimum wall thickness in this recess, a pair of cuts 9 are provided on opposite sides of the recess 3 in the lower portion 1; in this way, the place where the respective reinforcing rod 7 is driven through the insulation body is defined.
The studs 4 fit into the recesses 3 with frictional engagement such that upon joining the lower portion 1 and the upper portion 2 together, both portions are frictionally engaged with each other and may be separated from each other only with the exertion of force. In order to further increase the strength of this joint, as auxiliary studs 10 may be provided on the upper portion

The insulation body shown in Figure 1 is positioned, for example, between the floor panel of a balcony and an intermediate ceiling of a building. Preferably, the insulation body is disposed in the plane of the insulating plaster of the respective building wall. The insulatio~
body is contemplated to minimize the contact between the floor panel of the balcony on the one hand, and the intermediate ceiling on the other hand, thereby to provide for optimum heat insulation between these two structures.
~a2~7~
The insulation body comprises a lower portion 1 and an upper portion 2. The lower portion 1 is provided with recesses 3 arranged one behind the other(spaced from each other) in the longitudinal direction. The upper portion 2 includes studs or projections 4 opposing the recesses 3 of the lower portion 1. When upper and lower portion are jointed together, the studs 4 are fully receivedwithin the recesses.
Intermediate the studs 4, the lower side of the upper portion 2 has formed therein grooves 5 into which horizontally extending reinforcing rods 6 are pl~ced.
These reinforcing rods 6 act to absorb horizontal tensile forces. The lower edge of each stud 4 is cut under an angle to the horizontal. Reinforcing rods 7 passing obliquely through the insulation body are attached to this lower edge. Preferably, this lower side of each stud 4 is also provided with grooves ~ extending in parallel with the lower edge, with the reinforcing rods 7 being placed into these grooves and secured therein.
The reinforcing rods 7 also serve to absorb vertical forces. The reinforcing rods 6 or 7 may be secured within the grooves 5 or 8, respectively, by means of an adhesive or by means of clamps or clips fixed within the grooves.
The structure shown in Figure 1 is assembled in such a way that the reinforcing rods 6 and 7 are first inserted into the corresponding grooves 6 or 7 or secured to the associated surfaces. Then, the upper portion 2 and the lower portion 1 of the insulation body are joined togetherOIn this operation, the studs 4 are pressed into the respective recesses 3 to full length.
Hereby, the obliquely extending reinforcing rods 7 break up (cut through) the walls of the recesses 3 to a depth equal to the depth of penetration of these rods. The reinforcing rods 7 are positioned such that they come to meet the recesses in positions where the walls of the recesses are of minimum thickness. Therefore, the rein-forcing rods 7 produce only vertically extending slot-like cuts. Figures 2a and 2b show the cross-sectional configurations of two different recesses. In the hexa-gonal recess according to Figure 2a, the two positions where the wall of the lower portion has minimum thick-ness, are defined without any further measure. The reinforcing rods 7 are driven through the lower portion 1 between these two positions. Figure 2b illustrates a rectangular recess 3. In order to provide two defined positions of minimum wall thickness in this recess, a pair of cuts 9 are provided on opposite sides of the recess 3 in the lower portion 1; in this way, the place where the respective reinforcing rod 7 is driven through the insulation body is defined.
The studs 4 fit into the recesses 3 with frictional engagement such that upon joining the lower portion 1 and the upper portion 2 together, both portions are frictionally engaged with each other and may be separated from each other only with the exertion of force. In order to further increase the strength of this joint, as auxiliary studs 10 may be provided on the upper portion
2, and corresponding auxiliary recesses 11 may be formed in the lower portion 1, which recesses do not function to have reinforcing rods passing therethrough, but merely function to increase the frictional (engagement) force between upper and lower portions. Still further, the engagement may be improved by applying an adhesive to the contacting faces of upper and lower portions.
In the lower region of the lower portion, compression elements are disposed one behind the other in the longitudinal direction of the insulation body. These compression elements comprise, for example, a compression r7~
plate 12 of a rubber-elastic material and pressure-distributing layers 13 and 14 formed of a hard material and disposed on opposite sides of the compression plate 12, with the outer sides of these layers preferably lying in a common plane with the outer wall of the lower portion 1. Preferably, -the compression plate 12 and the layers 13 and 14 are adhesively bonded within the lower portion 1. The provision of the compression elements in the lower region of the lower portion 1 provides for good force transmission from the projecting plate or panel to the building.
According to Figure 1, the compression element is positioned directly under the recess 3 for ease of illustration. Normally, however, the recesses 3 and the compression elements are staggered relative to each other in the longitudinal direction of the insulation body in order to increase the strength of the lower portion which is preferably formed of a foamed material, such as polystyrene.
Figure 4 shows an upper portion 2 which is wider than the lower portion 1 and which, with these portions joined together, embraces or straddles the upper outer edge of the lower portion. This results in a still stronger joint between both portions. Further, this increases the length over which the reinforcing rods ~ 30 6 are guided by the insulating material, and thus the distance between the points where these reinforcing rods are clamped in the balcony panel on the one side and in the intermediate ceiling on the other side.
This structure provides the following advantage: The thermally insulating insulation body effects separation between the balcony (structure of varying temperature) and the building (structure of normally constant temperature). Accordingly, temperature-dependent 7'~
motions between balcony and building are in~uced, which place the horizontal reinforcing rods under tensile stress. The wider the spacing between the balcony panel and the intermediate ceiling, the smaller is the bending stress.
In order to mechanically fix the upper portion, this being of importance especially for transportation or shipment purposes, it is advisable to provide a long-itudinally extending reinforcing rod 15 within the upper portion. This reinforcing rod may be formed of wood, steel, plastic or the like, and it is inserted into the upper portion 2 or integrally cast thereinto by foaming during manufacture of the upper portion.
In order to provide for tight connection between upper portion 2 and lower portion 1 especially during transportation or shipment, the studs 4 of the upper portion may be provided with through holes 16 extending in the longitudinal direction of the insulation body, and the lower portion 1 may be provided with holes 17 likewise e~tending in the longitudinal direction between the recesses 3, and a rod is passed through these h~les when joining upper and lowex portions, to hold these portions together. In this instance, the lower portion may include a plurality of holes 17 disposed one above the other, such that the depth of insertion of the studs 4 may be varied.
Figure 6 illustrates the mounting of the lower portion prior to the mounting of balcony panel and inter-meaiate ceiling. The lower end of lower portion 1 is embraced by a U shaped holder 18 having a projection on its side which extends toward the balcony. This projection is tacked to the planking or casing 19 for the balcony panel. In a corresponding manner, it is also possible to mount the structure to the upper side of the building wall 20.
In order that the loaded construction element may be used for ceilings (ceiling panels) of different thicknesses, for example, of a thickness range of from 14 cm to 25 cm, a part of the lower portion 1 in the upper region thereof may be cut off, if necessary.
Accordingly, the studs 4 must not extend across the full length of the recesses 3. Normally, a cavity is therefore defined in the lower part of the recesses 3 even when the studs are fully inserted into the recesses. However, concrete cannot flow into this cavity in the subsequent casting of the balcony panel or intermediate ceiling (panel) as the recesses are closed at their upper ends by the studs and, as far as the walls of the lower portion 1 were broken up by the reinforcing rods 7, the resulting cuts are closed in downward direction by the reinforcing rods 7 proper~
The good thermal insulation provided by the insulation body is therefore secured.
In the lower region of the lower portion, compression elements are disposed one behind the other in the longitudinal direction of the insulation body. These compression elements comprise, for example, a compression r7~
plate 12 of a rubber-elastic material and pressure-distributing layers 13 and 14 formed of a hard material and disposed on opposite sides of the compression plate 12, with the outer sides of these layers preferably lying in a common plane with the outer wall of the lower portion 1. Preferably, -the compression plate 12 and the layers 13 and 14 are adhesively bonded within the lower portion 1. The provision of the compression elements in the lower region of the lower portion 1 provides for good force transmission from the projecting plate or panel to the building.
According to Figure 1, the compression element is positioned directly under the recess 3 for ease of illustration. Normally, however, the recesses 3 and the compression elements are staggered relative to each other in the longitudinal direction of the insulation body in order to increase the strength of the lower portion which is preferably formed of a foamed material, such as polystyrene.
Figure 4 shows an upper portion 2 which is wider than the lower portion 1 and which, with these portions joined together, embraces or straddles the upper outer edge of the lower portion. This results in a still stronger joint between both portions. Further, this increases the length over which the reinforcing rods ~ 30 6 are guided by the insulating material, and thus the distance between the points where these reinforcing rods are clamped in the balcony panel on the one side and in the intermediate ceiling on the other side.
This structure provides the following advantage: The thermally insulating insulation body effects separation between the balcony (structure of varying temperature) and the building (structure of normally constant temperature). Accordingly, temperature-dependent 7'~
motions between balcony and building are in~uced, which place the horizontal reinforcing rods under tensile stress. The wider the spacing between the balcony panel and the intermediate ceiling, the smaller is the bending stress.
In order to mechanically fix the upper portion, this being of importance especially for transportation or shipment purposes, it is advisable to provide a long-itudinally extending reinforcing rod 15 within the upper portion. This reinforcing rod may be formed of wood, steel, plastic or the like, and it is inserted into the upper portion 2 or integrally cast thereinto by foaming during manufacture of the upper portion.
In order to provide for tight connection between upper portion 2 and lower portion 1 especially during transportation or shipment, the studs 4 of the upper portion may be provided with through holes 16 extending in the longitudinal direction of the insulation body, and the lower portion 1 may be provided with holes 17 likewise e~tending in the longitudinal direction between the recesses 3, and a rod is passed through these h~les when joining upper and lowex portions, to hold these portions together. In this instance, the lower portion may include a plurality of holes 17 disposed one above the other, such that the depth of insertion of the studs 4 may be varied.
Figure 6 illustrates the mounting of the lower portion prior to the mounting of balcony panel and inter-meaiate ceiling. The lower end of lower portion 1 is embraced by a U shaped holder 18 having a projection on its side which extends toward the balcony. This projection is tacked to the planking or casing 19 for the balcony panel. In a corresponding manner, it is also possible to mount the structure to the upper side of the building wall 20.
In order that the loaded construction element may be used for ceilings (ceiling panels) of different thicknesses, for example, of a thickness range of from 14 cm to 25 cm, a part of the lower portion 1 in the upper region thereof may be cut off, if necessary.
Accordingly, the studs 4 must not extend across the full length of the recesses 3. Normally, a cavity is therefore defined in the lower part of the recesses 3 even when the studs are fully inserted into the recesses. However, concrete cannot flow into this cavity in the subsequent casting of the balcony panel or intermediate ceiling (panel) as the recesses are closed at their upper ends by the studs and, as far as the walls of the lower portion 1 were broken up by the reinforcing rods 7, the resulting cuts are closed in downward direction by the reinforcing rods 7 proper~
The good thermal insulation provided by the insulation body is therefore secured.
