Description

The present invention relates to a full thermal insulation for a fall as insulation of building facades, which is suitable to cover outside at least the area between a fall and the corresponding masonry, with a lintel, which is preferably formed as an insulating rectangular and elongated, wherein the insulating at least partially associated with a tissue, which is at least partially fixed to a rear side of the insulating plate and is loosely around an end face and a front side of the insulating plate at least partially umlegbar.

Such full thermal insulation is known in many forms and designs on the market and in use. For example, building facades with rigid foam panels glued as insulation, which is then applied after possibly a fabric reinforcement or a Gewebeabflachtelung a plaster.

DE 77 05 243 U discloses a full thermal protection according to the preamble of claim 1.

The disadvantage is that such insulation often breaks out especially in crash areas and formed in the wake of the new heat protection regulations in these areas cold bridges.

DE 90 01 808 U describes a finished component for Deckenranddownsteller, window lintels od. Like., In which an outer plate is used, which is designed as a three-layer plate. In this case, an insulating plate made of polystyrene foam is used as the outer plate.

The present invention is therefore an object of the invention to provide a full thermal protection of the type mentioned, which eliminates the disadvantages mentioned and with which in a very cost effective and simple manner, in particular the area of the fall should be very well insulated, while cold bridges are to be reduced.

To achieve this object, at least one elongated, rectangular, flat, strip-shaped strut element is integrated in a direction substantially perpendicular to the rear side or front side into a gap of this rear side or front side.

In the present invention has proven to be particularly advantageous to form a lintel element, made of an insulation, which preferably in the region of the lintel completely overlaps this upwards and downwards.

At the same time, the lintel may overlap the lintel downwards, so that a corresponding projection is formed, which also contributes to the reduction of the cold bridges. At the same time a corresponding projection creates a receiving space, for example. For shutter boxes or corresponding receiving boxes for fly screens od. Like., The outside of a window can be preset.

Thus, in particular the projection stiffness and high stability receives a longitudinal direction, the lintel element at least one strut element is assigned, in particular integrated in this.

So that the corresponding lintel can connect to a reinforcement to apply a plaster or fine plaster, this is additionally associated with a tissue, wherein the Tissue is firmly connected to a back and loose in the frontal and frontal area.

By the subsequent application of the additional Putzarmierung or the plaster is then connected in the frontal region and in the front region of this remaining tissue firmly connected to the protective element.

The lintel element has at least one strut element as defined in claim 1. The bracing element can be embedded in the front side or trapped on the back side in the lintel element, glued or the like. be.

It is also important in the present invention that, in particular in the region of the projection, at least one strut element can be provided, in particular to increase the rigidity of the lintel element.

Another strut can be glued eg on a front side of the lintel element. Likewise, it should also be considered that a further bracing element on the front side in the lintel element, for example. Insert into a gap, glue, clamp or the like .. The present invention is not limited to these other struts.

By inserting the bracing element, in particular in the region of the projection in the lintel element ensures that the projection of the lintel element does not distort, and no wave-like arches od. Like. Forms and is additionally reinforced and also withstand pressure or Sturmbeaufschlagungen. This should also be within the scope of the present invention. The lintel element can accordingly be produced in any desired length and is preferably of a thickness which corresponds to the conventional insulation. Preferably, the lintel element is made of rigid foam or of a rigid foam plate, wherein the bracing elements made of wood, metal, plastic or other materials. This should also be within the scope of the present invention.

Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawing; this shows in

• Figure 1 is a schematically illustrated cross-sectional view of a full thermal insulation for a fall as insulation of a building facade;
• Figure 2 is a schematically illustrated cross-sectional view through a building facade with integrated full thermal insulation with applied plaster;
• Figure 3 is a schematically illustrated partial perspective view of an inventive fall element for full thermal insulation;
• FIG. 4 shows a schematically illustrated perspective view of a further exemplary embodiment of the lintel element according to FIG. 3.

According to FIG. 1, a full thermal protection R according to the invention for a lintel 1 is formed from an insulation 2, the insulation 2 in the region of the lintel 1 being designed as a lintel element 3 according to the invention. The lintel element 3 consists essentially of the insulation 2 as an insulating plate, insulating foam od. Like., Which is preferably rectangular and elongated.

To ensure full thermal protection R, this lintel element 3 is glued to a building facade 4, screwed and otherwise fastened, so that the lintel element 3 completely overlaps the lintel 1, preferably overlaps downwards, so that a projection 5 is formed and upwards in such a way the Lint 1 overlaps, so that at least part of an overlying masonry 6 is additionally overlapped. In this way, a full heat protection R can be realized because the lintel element 3 completely overlaps the camber 1 in all directions. As a result, cold bridges are reduced or reduced.

Furthermore, it has proved to be important in the present invention to form the projection 5, so that between camber 1 and projection 5, in particular a window 7, a receiving space 8 is formed, which serves to accommodate a roller shutter box 9 or fly screen 10, see Figure 2 , In this way, the fall 1, in particular the receiving space 8 is additionally filled. Instead of the roller shutter box 9, for example, an additional insulation 2 can be used, should this be desired.

However, it is important in the present invention that the lintel element 3 can be reinforced by a fabric 11, as can be clearly seen in particular from FIG. Preferably, a complete back 12 is covered with the fabric 11, wherein the fabric 11 can be fixedly connected to the back 12, glued or otherwise attached.

This fabric can be folded or folded around an end face 13 toward a front side 14. The fabric 11 is firmly connected to the back 12 of the lintel element 3.

The fabric 11 gives the lintel element 3 additional stability and rigidity and further ensures that in particular a region of the fabric 11 in the region of the end face 13 or front side 14 with a plaster 15, see Figure 2, and a Putzarmierung 16 filled, if necessary, can also be connected overlapping. In addition, even after the application of the plaster 15 in the frontal region 13, a firm connection between the plaster 15 and the lintel element 3 is ensured, the fabric 11 supporting this connection.

A further advantage of the present invention is further that the crash element 3 at least one strut element 17 is assigned according to the characterizing part of claim 1. The bracing element 17 is of a width B which is slightly smaller than a thickness D of the crash element 3. The bracing element 17 is made as an elongated rectangular element made of wood, metal, composite material or plastic and can be inserted into a horizontally extending gap 18 be. The bracing element 17 is preferably used in the back 12, see Figure 3, over the entire length of the lintel element 3, in particular firmly glued or firmly connected to the insulation 2.

It corresponds to a gap depth T in about 1/3 to 2/3 of the thickness D of the lintel element 3. Preferably, a width B of the lintel element 3 in the same size of the gap depth T can be selected.

It is also important in the present invention, as shown in particular in the embodiment of Figures 2 and 3, that at least one strut element 17 in the region of the projection 5 in the lintel element 3, preferably near or in the region of the end face 13 is provided to the lintel element 3, viewed in the longitudinal direction to give a high rigidity.

Just as the lintel element 3 overlaps the lintel 1, this rigidity is in the region of the projection 5 required, so that a stiff and straight edge in the frontal region of the end face 13 is guaranteed as a completion of the full thermal insulation R or the building facade 4. According to one of the two variants of the characterizing part of claim 1, the strut element 17 is inserted approximately perpendicularly into the back 12 of the lintel element 3, wherein it is preferably thought to use a plurality of further strut elements 17 in the lintel element 3, preferably in the back 11 thereof ,

However, the further corresponding bracing elements 17 can also be used in the end face 13 and / or front side 14 of the lintel element 3.

It can also be thought that for lateral juxtaposition of individual lintel elements 3, at least part of at least one strut element 17 protrudes from a side wall 19 in order to bind the subsequent lintel element 3 adjoining thereto in an overlapping manner.

In this case, the lintel element 3 can be made in any lengths or be and serves in particular the full heat protection R of the lintel. 1
