Description

The present invention relates to a component for heat-insulating connection of two building parts, in particular between a building and an outer part projecting beyond the building, for example balcony or canopy, comprising a plate-shaped insulation body, loop-shaped tension elements inserted into the insulation body, which are substantially perpendicular to the arranged plate-shaped insulating body and above these are above, used in the insulating body pressure body and inserted into the insulating body, transverse forces receiving body having over the insulating body projecting areas.

With such components building parts made of concrete, such as balconies, connected to another part of the building or a building. In addition to the inclusion of the loads, these components should also be able to be connected to one another in such a way that as little heat transfer as possible should take place via these components, and thus the insulated outer layer of a building is not broken. In addition, these components should be equipped so that the best possible sound insulation is achieved between the two interconnected building parts. In particular, an optimal impact sound insulation should be obtained.

Such components are known from the prior art, for example, these consist of an insulating body, which is equipped with reinforcing bars, which penetrate the insulation body transversely. In the upper part of this insulating body claimable reinforcing bars are provided in the lower area can be used on pressure bracing reinforcing bars, the transverse forces occurring can be absorbed by obliquely running through the insulation body reinforcing bars.

Through these components, the forces can be absorbed easily, but by the reinforcing iron can take place a certain heat transfer from one building part to the other, a Impact sound insulation with reinforcing bars passing through the insulation body, which connect the two parts of the building, is not optimally guaranteed.

The object of the present invention is therefore to provide a component with which two parts of concrete formed building parts are connected to each other, which ensures optimum thermal insulation and impact sound insulation, in which the forces can be transmitted in an optimal manner, and easy and can be produced inexpensively.

According to the invention the solution of this object is achieved in that each of the above the surface of the insulating body projecting portions of the transverse forces receiving body two side surfaces, at least one side surfaces connecting the first surface area and at least one side surfaces connecting second surface area, which two surface areas are arranged inclined to each other and each have an inclination angle α of 20 ° to 45 ° with respect to the surface of the insulating body.

The loop-shaped tension elements used in the component can be made of a material which has a small coefficient of thermal conductivity, for example aramid, whereby a very low heat transfer takes place via these tension elements. The transverse forces receiving body can also be made of a material whose thermal conductivity is also small, whereby here the heat transfer can be kept as low as possible, also is by the configuration of this lateral forces receiving body, the power and transmission optimal. The forces acting, for example, on the first surface area from the one building part are transferred in an optimal manner by the second area of the body to the other component, the flow of forces is optimal.

Advantageously, the opposing, each above the insulating body projecting areas of a transverse forces receiving body symmetrical to each other. It can thereby be achieved that the component according to the invention can never be used in the wrong orientation between the two parts of the building to be connected, the transmission of the forces is always optimal in all cases.

Advantageously, the respective angle of inclination of the first area and the second area of the transverse forces receiving body with respect to the surface of the insulating body is about 30 °, whereby an optimal power transmission is achieved.

In an advantageous manner, the first area region and the second area region of the regions of the transverse forces receiving body projecting beyond the insulation body are each provided with a convex curvature, which avoids excessive pressure peaks occurring at the edge regions of these two surface regions.

A further advantageous embodiment of the invention is that the basic shape of the body receiving the transverse forces is essentially a regular hexagon. This ensures that the pressure-loaded surface areas are exactly opposite each other, which allows an optimal flow of forces.

A further advantageous embodiment of the invention is that the body receiving the transverse forces of a dimensionally stable foam, preferably polyurethane foam, are formed. This results in optimal thermal insulation. These transverse forces receiving bodies are wrapped with high-strength fibers, which are embedded in synthetic resin. In particular, by the hexagonal shape of the body, the wrapping can be done with these high-strength fibers in an optimal manner, these high-strength fibers may be glass fibers or advantageously fibers of aramid.

Advantageously, the pressure bodies are formed from a fiber-reinforced plastic, which also optimal thermal insulation and impact sound insulation can be achieved. These pressure bodies are each with a body receiving the transverse forces Wrapped with high-strength fibers connected to each other, the fibers are embedded in plastic. On the one hand, this results in a reinforced overall body, on the other hand, thereby the manufacture of respective components can be simplified.

In an advantageous manner, outwardly directed surfaces of the pressure body are respectively provided with a pressure plate with respect to the insulation body, whereby the force absorption is improved.

A further advantageous embodiment of the invention is that the insulating body comprises a first substantially cuboidal shell, in which the body receiving the transverse forces and the pressure body are arranged, the cavity is filled with insulation material. This results in a simple production of one part of the insulating body.

Advantageously, the insulation body comprises a second substantially cuboidal shell in which the tension elements are mounted, the cavity is filled with insulation material. This second part of the component can thus be easily produced. Advantageously, the first shell and the second shell are provided with connecting means with which these two shells are connectable to each other.

A further advantageous embodiment of the invention is that between the first shell and the second shell, a third shell, which is formed substantially cuboid, can be used, which is also provided with connecting means, via which the third shell with the first shell and the second shell is connectable, and the cavity of the third shell is also filled with insulation material. As a result, the components can be assembled in a modular system, in particular, the components can be produced in a simple manner with different heights, the basic elements of such a component can be used uniformly. In addition, this component can be inserted from above into the parts of the building to be connected after laying the reinforcement.

Out Fig. 1 is an inventive component 1 for heat-insulating connection of two parts of the building can be seen, which is shown spatially. A view of an inventive component shows Fig. 3 , These two figures can be deduced that the component 1 comprises a plate-shaped insulating body 2, which may be constructed in several parts, as will be seen later in detail. In the upper part of the plate-shaped insulating body 2, the loop-shaped tension elements 3 are used. These loop-shaped tension elements 3 form endless loops, which are inserted into the plate-shaped insulating body 2 in such a way that they are arranged perpendicularly to this and project above it. About this loop-shaped tension elements can be absorbed by the two components to be joined, in which the loop-shaped tension elements 3 are cast in, acting tensile forces. This loop-shaped tension elements 3 are advantageously made of aramid, which has a very low thermal conductivity and a very high tensile strength. Of course, other suitable materials, which have the corresponding physical characteristics, conceivable.

While the loop-shaped tension elements 3 in the component 1, as in Fig. 1 is shown, are embedded in an upper region in the insulating body 2, 2 pressure body 4 are used in the lower part of this insulating body, which will be described later in detail. In the embodiment shown here, the juxtaposed and embedded in the insulating body 2 pressure body 4 are covered by pressure plates 5, via which the recording of the compressive forces can be improved in a known manner. In the embodiment shown here, each pressure body 4 is covered on both sides with a separate pressure plate 5, it would also be readily conceivable that a plurality of juxtaposed pressure body 4 could be covered by a common pressure plate 5.

In the insulating body 2 of the component 1 between the areas in which the loop-shaped tension elements 3 and the pressure body 4 are used, transverse forces receiving body 6 is inserted. These bodies 6, which will be described later in detail, penetrate the insulating body 2 and have on both sides on the respective surface 7 of the insulating body 2 projecting areas 8.

As in particular from Fig. 6 can be seen, these protruding portions 8 of the transverse forces receiving body 6 are formed by two side surfaces 9, which are aligned in the embodiment shown here substantially parallel to each other. These two side surfaces 9 are connected by a first surface region 10 and a second surface region 11. The first surface region 10 and the second surface region 11 are inclined relative to one another, with respect to the surface 7 of the insulation body 2 the first surface region 10 and the second surface region 11 each have one Inclination angle α of preferably 30 °, as will be seen in more detail later. The first surface region 10 and the second surface region 11 are each provided with a convex curvature 12, as will also be seen in detail later.

Fig. 2 shows a view of a lateral forces receiving body 6, or its basic shape. This body, which absorbs the lateral forces, consists of a regular hexagon. The over the surface 7 of the insulating body 2 ( Fig. 1 ) projecting areas 8 and the first surface areas 10 and second surface areas 11 each have an angle of inclination α of 30 °. From the sectional views according to 4 and FIG. 5 are the convex curvatures 12 can be seen, which have the respective side portions 10 and 11. Out Fig. 2 It can be seen that at this transverse forces receiving body 6 also the pressure body 4 may be formed. This transverse forces receiving body 6 may be made of a suitable pressure-resistant material. The pressure body is also made of a pressure-resistant material. Of course, pressure body 4 and transverse forces receiving body 6 separated from each other and individually in the component according to Fig. 1 be used.

This transverse forces receiving body 6 may also be formed as a foam body, for example of a polyurethane foam. The shaping takes place in a known manner by foaming a appropriate form. Of course, other suitable manufacturing methods are conceivable. This foam body is used only for shaping this transverse forces receiving body 6, this foam body is, as will be described below, correspondingly reinforced to achieve the required strength, so that the forces can be transmitted.

Fig. 7 shows a transverse forces receiving body 6, which has been described above, can be formed from a foam, on these transverse forces receiving body 6, the pressure body 4 can be attached, for example by gluing, this pressure body 4 consists for example of a glass fiber reinforced plastic, the For example, from an extruded solid profile made of fiberglass reinforced plastic can be tailored.

Fig. 8 shows a first way in which the lateral forces receiving body 6 and the pressure body can be reinforced. These two bodies are wrapped with high-strength fibers 13, these fibers 13 may be, for example aramid fibers conceivable would be glass fibers. In known manner, these high-strength fibers to be wound 13 may be impregnated in epoxy resin, so that an optimal connection is formed. Preferably, in this case, the mutually opposite respective first surface regions 10 and second surface regions 11 of the transverse forces receiving body 6, which is formed as a regular hexagon, are wrapped in layers. In addition, the upper side 14 of the transverse forces receiving body 6 and the lower surface 15 of the pressure body 4 is wrapped, each wrapped in a winding surfaces are in this case parallel to each other, which simplifies the winding. So several winding layers can be stored one above the other. The foam-made body 6 serves to prevent the layer formed by the windings from bulging or creasing and thus to be able to absorb and transmit the forces acting in their full extent. The convex curvatures 12 of the first area region 10 and of the second surface regions 11 are in this case semicircular, whereby the hydrostatic concrete pressure is optimally absorbed as membrane stress in the windings can be and the existing foam body 6 is not charged. Of course, the transverse forces receiving body 6 can also be wrapped and used individually without attached pressure body 4.

Fig. 9 shows in principle the same constellation as in Fig. 8 has been described, wherein the individual winding layers in the central region of the transverse forces receiving body 6, a fabric-like structure is formed and thereby optimum strength is achieved. Of course, it would also be conceivable to wrap only the transverse forces receiving body 6 as described above, the pressure body 4 can be readily prepared separately and also separately, that is from the transverse forces receiving body 6 separated in the plate-shaped insulating body 2 (FIGS. Fig. 1 ) are used.

By the above-described amplification process to obtain a transverse forces receiving body having the desired strength, which is optimally formed with respect to low thermal conductivity and low impact sound insulation, and can absorb and transmit the pressure forces occurring in an optimal manner.

Fig. 1 shows a component 1, in each of which under each tension element 3, a transverse forces receiving body 6 and a pressure body 4 is arranged. Depending on the occurring forces of two building parts to be joined together, the arrangement and number of tension elements 3, transverse forces receiving bodies 6 and pressure bodies 4 can be adjusted accordingly. Thus, for example, the distance between the tension elements 3 can be changed from one another, so that more or fewer tension elements 3 per component can be arranged, and the number of transverse forces receiving body 6 and the pressure body can be varied virtually arbitrarily.

How out Fig. 10 can be seen, the insulating body 2 may be formed of a first, substantially cuboidal shell 16, on which a second, substantially cuboidal shell 17 is placed and over Connecting means 18 may be interconnected. In the first shell 16, which may be formed of a suitable plastic, the transverse forces receiving body 6 and the pressure body 4 are inserted into corresponding recesses. The remaining in the first shell 16 cavities can then be filled with an insulating material, for example with an insulating airgel. As has already been described, corresponding pressure plates 5 can be placed on the pressure bodies. In the second shell 17, the non-illustrated loop-shaped tension elements can be used in corresponding recesses, the cavities remaining in the second shell 17 can also be foamed by an insulating airgel. About the connecting means 18, which are formed for example as snap closures, the first shell 16 and the second shell 17 can be assembled in a simple manner, whereby one obtains a component 1 according to the invention. In known manner, the first shell 16 and the second shell 17 may be formed of two half-shells, which can also be joined together by snap closures, in particular the insertion of the loop-shaped tension elements 3 in the second shell 17 is thereby greatly simplified.

How out Fig. 11 can be seen, between the first shell 16 and the second shell 17, an intermediate piece in the form of a third substantially cuboidal shell 19 are used, this third shell 19 is also foamed with an insulating airgel, which can be achieved in a simple manner, the component 1 to produce at different heights, wherein the first shell 16 may be formed with the transverse forces receiving bodies 6 and the pressure bodies 4 and the second shell 17 with the loop-shaped tension members each as a unit part, whereby the production can be simplified.

With this embodiment according to the invention, a component is obtained which can optimally connect two parts of the building. This component is used from above between the building parts to be manufactured and in the finished reinforcement, these building parts are concreted, after curing of the concrete, these building parts are optimally connected via the component inserted therebetween, the tensile forces are on the transfer the loop-shaped tension elements, the compressive forces are transmitted through the pressure hull, the lateral forces are absorbed and transmitted through the transverse forces receiving body, with optimum thermal insulation and optimum footfall sound insulation is achieved. The component is formed symmetrically with respect to the parts of the building to be connected, which means that the component can not be reversed between the two parts of the building to be used, corresponding incorrect assembly are excluded. Due to the possibility of height adjustment, these components can be used in a variety of ways in a uniform form.
