Description

 Component for thermal insulation

Technical area

The invention relates to a component for thermal insulation between two components to be concreted, in particular between a supported component and a supporting component of a building, at least consisting of a thermally insulating body to be arranged therebetween with at least integrated pressure elements which traverse the thermally insulating body and in each case to both components can be connected.

State of the art

Such components for thermal insulation are known in the relevant prior art in many different designs for a variety of installation and connection situations. With them, two components, in particular a supported exterior component, for example a balcony slab, and a supporting interior component located in the thermally insulating building interior, for example a ceiling slab, are thermally decoupled from one another in order to reduce the thermal bridge in this area, but also at the same time statically connected to one another. This static connection takes place via reinforcing elements, which are referred to by a thermally insulating body, commonly referred to as insulating body or insulator, extend and embed in the adjacent components. The reinforcing elements transmit the loads occurring by the supported component, in particular compressive, tensile and / or transverse forces, in particular vertical and / or horizontal transverse forces acting on the supporting component. Depending on the component used for the respective installation and connection situations, the loads as well as the reinforcement elements, in particular pressure elements, traction elements and / or shear force elements required for the transmission vary depending on the embodiment of the connected components, so that a variety of embodiments for a device for thermal insulation results. Due to weather-related temperature fluctuations occur on the outer components length changes. This causes temperature-related relative movements between the two components, ie between the outer component and the inner component, as a result of which the reinforcing elements connecting the two components are deflected by several millimeters. For the traction elements and the transverse force elements, this is usually no problem, since they are usually designed to be very slim. The situation is different with the pressure elements, which are usually designed to increase the bending stiffness massive and massive.

From the prior art, in particular from DE 4102332 C2, DE 9318354 U1 and DE 20011960 U1, components for thermal insulation are known, each comprising an insulating body and pressure elements, wherein the pressure elements are formed in several parts and each of a closed hollow profile, At the opposite ends flat cover plates are arranged, exist. The pressure elements extend through the insulating body, stand at both ends on the insulating body and are clamped in the adjacent components. Due to the temperature-related relative movements between the two components, however, it can cause concrete chipping and fatigue failure in the clamping of the printing elements.

Furthermore, from WO 03/054313 A1 a component for thermal insulation is known, which likewise comprises an insulating body and pressure elements, wherein the pressure elements are formed in several parts and each consist of a closed hollow profile, at its opposite ends flat cover plates are arranged. The pressure elements extend through the insulating body, but they terminate flush with the insulating body, so that the components facing flat contact profile surfaces of the flat cover plates act as sliding surfaces. Due to the flat contact profile surfaces of the flat cover plates, however, pressure elements which, in order to ensure a sliding movement, are structurally very voluminous and require very large contact profile surfaces, so that the pressure elements require a high material requirement. In addition, these printing elements have the disadvantage that with increasing width or thickness of the insulating body and thus with increasing length of the printing elements, the compressive stresses in the edge region of the contact profile surfaces of the printing elements on the printing elements themselves and on the adjacent components, due to the horizontal temperature-related relative movements and the vertical settlement movements between the two adjacent components, so that the compressive pressure of the pressure elements decreases.

Furthermore, components for thermal insulation are known from the prior art, which in addition to an insulating body have one-piece pressure elements. Thus, for example, EP 0933482 B1 proposes rectangular pressure elements made of a concrete mixture which, at least on the side facing the building, each have a sliding layer in order to ensure a sliding movement between the pressure element and the adjacent component of the building.

One-piece pressure elements are also known from the prior art which, like a joint element or pendulum rod, transmit the forces between the two components, therefore between the outer component and the inner component. For example, EP 1225282 A2 proposes a thermal insulation component comprising an insulating body and pressure elements, wherein the pressure elements are made of concrete and extrusion, whereby the extrusion direction of the pressure element extends vertically to the horizontal longitudinal extent of the insulating body, or casting, wherein for this purpose is used as sliding layer acting mold, are produced. A disadvantage of these printing elements, however, is that for printing elements of different lengths, which are required for insulating bodies of different widths and thicknesses, different production forms for the extrusion or else for the casting molds are required. This causes high costs. One-piece printing elements which are produced using a lost mold are also known from EP 1225283 B1 and EP 1669501 A1. For this purpose, it should be noted that these pressure elements have contact profiles facing the components and that the pressure elements are provided with a sliding layer in the region of their end-side contact profiles, which are each formed by the sliding layer. A shaping production of the printing elements with respect to the contact profiles is necessary in any case.

Finally, from DE 102004020914 A1, a component for thermal insulation is known, which comprises an insulating body and one-piece pressure elements, wherein the pressure elements are convexly curved at their end faces facing the components and equipped with a lubricant, wherein the lubricant is a positive socket acts, which allows movement of the pressure element in the socket, while the socket itself, relative to the adjacent component, does not move. For this purpose, the socket is designed so that the inner diameter of the socket is greater than the outer diameter of the Pressure element. A disadvantage of these printing elements, however, is that the curved end faces of the printing elements must be made by a shaping processing. For this purpose, a special device and a complex monitoring and quality control is necessary, which also causes high costs.

Presentation of the invention

Proceeding from this, the present invention has the object to provide a structural element for thermal insulation, the pressure elements can absorb the temperature-related relative movements between the adjacent components particularly advantageous and also in a simple and high quality manner, in one of the width and thickness of the thermally insulating body the component adapted length, are inexpensive to produce.

This object is achieved in that the pressure elements consist of at least several mutually firmly connected sections, which at the transverse through the thermally insulating body extending portions subsequent sections each have their components facing end faces a curved contact profile, and that the pressure elements make a joint between the two components.

The element according to the invention for thermal insulation connects two components together and consists essentially of a thermally insulating body and of reinforcing elements, which are the loads occurring, in particular compressive forces and tensile and / or shear forces, in particular vertical and / or horizontal transverse forces acting through the Be caused component, transferred to the supporting component. The loads as well as the reinforcement elements required for the transmission of the loads, in particular pressure elements and traction and / or shear force elements, vary depending on the component used for the respective installation and connection situations for thermal insulation. While the reinforcing elements, for example, in a supported component, which requires no further support, transmitted tensile, compressive and shear forces, so it is in a supported component, which is additionally supported at its end, only the compressive and lateral forces, by the Reinforcement elements are transferred The concave cross section of the curved contact profiles of the end faces expediently extends over the entire height, so that a relevant possibility of the embodiment is that the curved contact profiles of the end faces have the negative shape of a surface segment of a cylinder jacket surface.

In addition, there is a preferred embodiment of the curved contact profiles of the end faces in that they are arched in a vertical section in a circular arc inwardly, preferably concave, are formed. As a result, the contact profiles of the end faces can follow not only the horizontal temperature-related relative movements but also the vertical settlement movements between the two components. The printing elements thus designed are thus articulated in the horizontal and in the vertical direction.

Of course, it is also within the scope of the invention that the curved contact profiles of the end faces in horizontal section and / or in vertical section not only arcuately inwardly curved, preferably concave, but also arcuately outwardly curved, preferably convex, may be formed.

Since the pressure elements via their curved contact profiles of the end faces can follow the relative movements occurring between the components by a relative movement or displacement in the contact area of the contact profiles relative to their adjacent component, they are always with their frontal contact profiles on the entire surface of the adjacent components.

Depending on the cross section of the end faces of the end sections of the printing elements, it is also useful if the rounding diameter of the horizontal curvature of the contact profiles and the rounding diameter of the vertical curvature of the contact profiles of different sizes, for example in an elliptical or rectangular cross section, or the same size, for example in a round or square cross section, are.

According to a preferred embodiment of the present invention, the curvature of the contact profiles of the end faces substantially ends with the lateral wall of the end-side sections of the pressure element, so that the curvature of the contact profiles of the end faces extends substantially over the entire cross-section of the end sides of the end-side sections of the pressure element, thereby to achieve the largest possible contact profile area. According to a further preferred embodiment of the present invention, the cross-section of the curvature of the contact profiles of the end faces is less than the cross section of the end faces of the end-side sections of the pressure element, so that the end-side sections of the pressure element in the front view of the contact profiles have an outer facing the adjacent components wall. It is advantageous if an elastic material is arranged on the outer wall and / or if the outer wall is elastic or flexible, so that the relative movement of the pressure element is ensured.

According to a particularly preferred embodiment of the present invention, the cross section of the end faces facing the components of the end sections is greater than the cross section of the middle extending transversely through the thermally insulating body portion, so that the end portions have an expanded cross section in the form of a protruding relative to the central portion Have partial area. It is advantageous if this projecting portion is elastic or flexible, so that the relative movement of the pressure element is ensured.

In order to ensure the articulation of the pressure elements between the two components in an optimal manner, it is advantageous if the curved end-side contact profile surfaces of the end-side sections of the printing elements have a particularly smooth surface, so that the friction to the concrete of each adjacent component is low.

In this context, it is also recommended that the length of the printing elements substantially corresponds to the width or thickness of the thermally insulating body.

In addition, the length of the printing elements may also be smaller than the width or thickness of the thermally insulating body. The thermally insulating body has for this purpose on the components facing the end faces of the pressure elements recesses into which flows during installation of the device for thermal insulation of the concrete. The recessed installation of the pressure elements has the advantage that the pressure elements and thus also the contact profile surfaces have better thermal protection over their end faces facing the adjacent components, which increases the fire resistance duration in the region of the end faces. Thus, it is for example possible components for thermal insulation, which also have a fire protection element on the top and bottom of the thermally insulating body, with alkali-resistant pressure elements made of plastic or fiber-reinforced 8th

Plastic, especially plastic-, basalt-, glass- and / or carbon fiber reinforced thermoplastics or thermosets, with a fire resistance time required for apartment building.

The middle section of the pressure element, which extends transversely through the thermally insulating body, may in principle have any desired cross section. However, the cross section of a closed solid or hollow profile in a circular, round, elliptical, square or rectangular shape is preferred. The preferred cross-sectional dimensions of the middle section are in the height and width between about 3 and 6 centimeters, in particular cross-sectional dimensions with dimensions (hereinafter height and width in centimeters) 4 x 4, 4 x 5, 4 x 6, 5 x 4, 5 x 5, 5 x 6, 6 x 4, 6 x 5 and 6 x 6 are preferred.

Furthermore, the end sections which are fixedly connected to the middle section may have any desired shape. The end-side sections are preferably designed so that they have a circular, round, elliptical, square or rectangular shape in the front view, wherein the components facing cross-sectional area of the end faces of the end-side sections in size at least that of the central portion which transversely extends through the thermally insulating body corresponds to enclosed vertical sectional area.

The individual sections of a respective pressure element consist of a pressure-resistant material, in particular plastic and / or mineral base material comprehensive material, such as concrete, high-strength concrete, ultra-high-strength concrete, foam concrete, lightweight concrete, ceramic, especially foam ceramic, or other appropriate pressure-resistant material, said the pressure-resistant material is optionally reinforced with fibers, in particular steel, plastic, basalt, glass and / or carbon fibers. Furthermore, the individual sections made of the same materials or else, this embodiment is particularly preferred, consist of different materials, so that there is a pressure element that optimally and cost-effectively fulfills a wide variety of requirements.

When using plastic, in particular polyamide, polyoxymethylene, polyethylene terephthalate, polyethylene, polypropylene, polytetrafluoroethylene, polyvinylidene fluoride, polyetheretherketone, phenol resin, polyurthane or another suitable polymer, for the sections of the printing elements, this preferably has a density of at least 0.5 grams / Cubic centimeters, in particular at least must, so that the latter can be dispensed with traction elements. The pressure elements are necessary in both load cases.

According to a preferred embodiment of the present invention, the pressure element consists of a middle extending transversely through the thermally insulating body portion at the opposite ends of which are connected to the middle section fixedly connected end-side sections form fit. The pressure element therefore consists of three sections. The middle section extending transversely through the thermally insulating body has planar contact profile surfaces on its end faces facing the end sections. The form-fitting adjoining the central portion end portions have at their component facing end faces each have a curved contact profile, which is preferably circular arc-shaped, so that the pressure element articulation between two components, in particular between a worn outer component, such as a balcony slab, and a carrying inner component, such as a ceiling plate, manufactures.

The shaping curved contact profile, which produces the articulated connection of the pressure element between the two components, is consequently formed by a respective end-side portion of the pressure element, wherein due to the curvature of the contact profile, the layer thickness of the respective end portion varies depending on the configuration of the curvature horizontally and / or vertically , An elaborately curved, shaping processing of the end faces of the middle extending transversely through the thermally insulating body portion of the pressure element is therefore not necessary.

In order to record the temperature-related relative movements between the adjacent concrete components particularly advantageous, the curved contact profiles of the components facing end faces of the end-side sections of the printing elements are designed in such a form that they in horizontal section, therefore in the direction of the greatest change in length of the outer component or parallel to the substantially longitudinal extension of the thermally insulating body, arcuate inwardly curved, preferably concave, are formed. As a result, an unhindered and symmetrical relative or sliding movement is made possible on both opposite curved contact profiles, wherein the pressure elements roll over their curved contact profiles of the end faces of the adjacent components and thus produce the hinge connection. 2.0 grams / cubic centimeter, and a thermal conductivity of less than 0.6 watts / (meters x Kelvin), in particular less than 0.3 watts / (meters x Kelvin), on.

When using foamed concrete or lightweight concrete, in particular lightweight lightweight concrete with grain porosity or haufwerkporiger lightweight concrete with porous aggregates, for the sections of the printing elements, this preferably has a bulk density between about 300 and 2000 kilograms / cubic meter, a thermal conductivity between about 0.2 and 2, 0 watts / (meter x Kelvin), a compressive strength between about 30 and 150 Newton / square millimeters, and a Young's modulus between about 5,000 and 50,000 Newton / square millimeter.

In addition, the end-side sections of the pressure element can also each consist of several, preferably two, sub-elements which are firmly connected to each other. The respective end portion is in this case preferably designed so that the at the middle extending transversely through the thermally insulating body portion adjacent part of a low-cost material, such as plastic, or a temperature-resistant material, such as ceramic or heat-resistant plastic, while the other Subsequent sub-element of a material, such as plastic, consists, which has a low coefficient of friction to the concrete of each adjacent component. The individual sub-elements of the respective end-side section are firmly connected to each other by gluing, plugging and / or pressing or another convenient method.

The multi-part structure of the printing elements and its articulated design makes it possible to optimally design the individual sections of the printing elements to a variety of requirements in terms of constructive design of the printing elements, the individual sections may consist of the same but also of different materials, the optimal according to their specific material properties can be tailored to the different requirements of the printing elements. This allows a wide variety of embodiments of printing elements with different material combinations.

According to a preferred embodiment of the present invention, the middle section has the cross-section of a hollow profile, wherein it preferably consists of fiber-reinforced plastic. The end-side sections are preferably made of plastic or fiber-reinforced plastic. This results in a pressure element with particularly low thermal conductivity and thus very good thermal insulating properties. According to a further preferred Ausführurigsform of the present invention, the middle portion has the cross section of a solid profile, wherein it is preferably made of fiber reinforced plastic, wherein for the fiber reinforced plastic preferably hollow glass fibers are used, on the one hand on the end-side sections and on the other hand on the plastic matrix of the middle section to be protected from corrosion. Conveniently, an additional anti-corrosion coating can be used. This should consist of diffusion-inhibiting material, in particular stainless steel or plastic. The end-side sections are preferably made of plastic or fiber-reinforced plastic. This results in a pressure element with even lower thermal conductivity and thus again improved thermal insulating properties and increased fire resistance.

Alternatively, the end sections can also be made of a more temperature-resistant material, such as fiber reinforced concrete, ceramic, in particular foamed ceramic, heat-resistant plastic or heat-resistant fiber-reinforced plastic, as the middle portion which extends transversely through the thermally insulating body. The loss of strength of the end portions is therefore lower with increasing temperature than that of the central portion. The thermally insulating effect of the end sections results in the advantage that the middle section has better thermal protection over the end sections facing the adjacent components facing end sides, whereby the fire resistance of the middle section increases in this critical area. Thus, it is possible to offer components for thermal insulation, which also have a fire protection element on the top and bottom of the thermally insulating body, with sections made of plastic or fiber-reinforced plastic in a necessary for the apartment building fire resistance period.

According to a particularly preferred embodiment of the present invention, the central portion, which extends transversely through the thermally insulating body, the cross section of a solid profile, wherein it is preferably made of a mineral material, in particular lightweight concrete. The end-side sections are preferably made of plastic or fiber-reinforced plastic, where they have a low coefficient of friction to the concrete of each adjacent component. This results in a pressure element that is not only very cost-effective due to the low material costs for the lightweight concrete of the middle section and the low material consumption of the more expensive plastic end-side sections, but also has very good thermal insulating properties due to the material-specific properties of the individual materials.

The multi-part construction of the printing elements also favors the cost-effective production of printing elements of different lengths, which can be adapted to the respective width or thickness of the thermally insulating body of the components for thermal insulation. In this case, only the middle section of the pressure element has to be varied in its length. This is very cost-effective, since directed production methods, such as extrusion, pultrusion or extrusion, correspond to the longitudinal direction of the middle section of the printing element, so that only a length cut must be made. Furthermore, this results in a section, in particular if it consists of fiber-reinforced plastic whose reinforcing fibers extend for the most part in the longitudinal direction of the section, therefore parallel to the section, resulting in an optimal utilization of the material with respect to the compressive strength and bending stiffness.

The end-side sections can, if they are made of plastic or fiber-reinforced plastic, for example, by injection molding or foam casting and in the form of a molded part, such as a cap, be formed.

Furthermore, the printing elements according to the invention can be produced or assembled particularly easily. For this purpose, only the individual sections are to be connected by gluing, plugging and / or pressing each other.

Due to the multi-part construction of the pressure elements also results in the advantage that the central portion of the pressure element can be performed in the form of a closed hollow profile, which may also be provided with thermally insulating material. The thermally insulating material can be introduced into the cavity of the middle section by inserting or foaming. As a thermally insulating material are expanded or extruded plastics, such as polyurethane, polyisocyanurate, phenolic resin or polystyrene, which are optionally mixed with graphite and / or elasticized, mineral foam, foam glass, mineral wool, especially glass or rock wool, or other appropriate material, where It may also be sound-absorbing material and / or fire protection material.

The thermally insulating body of the component consists at least of a heat-insulating material, preferably expanded or extruded plastics, For example, polyurethane, polyisocyanurate, phenolic resin or polystyrene, which are optionally mixed with graphite and / or elasticized, mineral foam, foam glass, mineral wool, especially glass or rock wool, or other appropriate material, which is also sound-insulating material and / or Fire protection material can act. The material used for the thermally insulating body preferably has a bulk density of at least 10 kilograms / cubic meter, in particular at least 30 kilograms / cubic meter, and a thermal conductivity of less than 0.045 watts / (meters x Kelvin), in particular less than 0.025 watts / (meters x Kelvin) , on.

Advantageously, the pressure elements are fixed in the existing recesses of the thermally insulating body by plugging and / or gluing.

In summary, it follows from the multi-part structure of the printing elements and its articulated execution the advantage that the individual sections of the printing elements can be optimally designed for a variety of requirements in terms of constructive design of the printing elements, for the individual sections of various materials can be used according to their specific material properties can be optimally adapted to the various requirements of the printing elements. This allows a wide variety of embodiments of printing elements that meet any requirements in terms of their structural and structural properties, their behavior under temperature stress and compressive stress and their ease of installation and their low production costs. Furthermore, there is the significant advantage that the printing elements can be produced cost-effectively in a simple and high-quality manner, in a length adapted to the width or thickness of the thermally insulating body of the component, so that the printing elements are particularly well suited for component systems whose Construction elements for thermal insulation vary in width or thickness.

The pressure elements described here can be used for components for thermal insulation as well as components for sound insulation in cantilevered or supported Baikon, arcades, loggia, consoles, Attiken, balustrades, canopies, cantilevers and / or wall panels and stairs, staircases and the like, or for other applications in which two components are to be decoupled from each other at least thermally. In the following, some embodiments of the present invention will be illustrated with reference to drawings and explained in more detail.

FIG. 1 shows a detail of a first embodiment of a component for thermal insulation in a schematic horizontal section, which is shown in FIG. 2 in a schematic vertical section of FIG. 1 along the plane AA. The structural element 1 for thermal insulation according to Figure 1 and Figure 2 is disposed between a supported component A and a supporting member B and consists essentially of a thermally insulating body 2 and of reinforcing elements in the form of pressure elements 3 shown in Figures 1 and 2, wherein a plurality of printing elements are arranged perpendicular to the plane of the vertical section according to Figure 2 one behind the other. The thermally insulating body 2 is usually penetrated by the known from the prior art reinforcing elements for receiving the tensile and / or shear forces, was waived their representation to relieve the figure.

The pressure element 3 traverses the thermally insulating body 2 essentially horizontally from component A to component B and substantially ends with the thermally insulating body 2. The length of the pressure element 3 therefore substantially corresponds to the width or thickness of the thermally insulating body 2. The pressure element 3 is radially symmetrical and consists of a central portion 4, at its opposite ends with the central portion 4 fixed end sections 5, 6th are arranged. The central portion 4 has the cross section of a closed hollow profile in a circular shape, wherein in the cavity 13 of the central portion 4 thermally insulating material 14 is arranged.

At the middle section 4 facing end sides of the end-side sections 5, 6 is located each end-side section 5, 6, a conical connecting pin 11, 12 whose outer diameter is smaller than the inner diameter of the hollow central portion 4, so that a non-positive and positive Connection of middle section 4 and end sections 5, 6 is ensured. The end-side sections 5, 6 are for this purpose attached to the central portion 4 of the pressure element 3, wherein the sections 4, 5, 6 are glued at least locally to each other at their contact surfaces. Furthermore, the end-side sections 5, 6 at their the component A, B facing end faces 9, 10 curved contact profiles, which initiate the compressive force in the pressure element 3 and discharge into the adjacent component and thus transferred. The contact profiles of the end faces 9, 10 are in accordance with the horizontal section shown in Figure 1 and the vertical section shown in Figure 2 curved arcuate inwards, wherein the curvature of the contact profiles is the same size. The contact profiles of the end-side sections 5, 6 thus have the negative shape of a surface segment of a spherical lateral surface. In order to keep the friction to the concrete of the adjacent components A ₁ B as low as possible, the contact profile surfaces of the end faces 9, 10 of the end sections 5, 6 executed particularly smooth.

The portion 27 shown in Figure 7 consists of the sub-elements 28 and 29, wherein it also has a concave contact profile. Due to the Verrasterung the two sub-elements can be easily connected to each other.

FIG. 8 shows a detail of a second embodiment of a component for thermal insulation in a schematic horizontal section, which is shown in FIG. 9 in a schematic vertical section of FIG. 8 along the plane AA. The structural element 31 for thermal insulation according to FIG. 8 and FIG. 9 is arranged between a supported component A and a supporting component B and consists in Essentially from a thermally insulating body 32 and from reinforcing elements in the form of pressure elements 33 shown in FIGS. 8 and 9, wherein a plurality of pressure elements are arranged one behind the other perpendicular to the plane of the vertical section according to FIG. The thermally insulating body 32 is usually penetrated by the known from the prior art reinforcing elements for receiving the tensile and / or shear forces, was waived their representation to relieve the figure.

The pressure element 33 traverses the thermally insulating body 32 essentially horizontally from component A to component B, with its sides facing the components A ₁ B protruding from the thermally insulating body by only about 1 millimeter to 3 millimeters. The length of the pressure element 33 therefore substantially corresponds to the width or thickness of the thermally insulating body 32. The pressure element 33 is formed mirror-symmetrically in the horizontal transversely to its longitudinal extension and consists of a central portion 34, which preferably consists of a mineral material to whose opposite ends with the central portion 34 fixedly connected end portions 35, 36, which are preferably made of plastic, are arranged. The central portion 34 has a substantially rectangular cross-section and is cuboidal. Further, the middle portion 34 on its the end-side sections 35, 36 facing end faces 37, 38 planar contact profile surfaces. The end-side sections 35, 36 are cap-shaped, wherein they enclose the middle section 34 positively, so that they can be applied and fixed by gluing, plugging and / or pressing on the central portion 34.

The end-side sections 35, 36 have, at their end faces 39, 40 facing the components A ₁ B, arched contact profiles for the introduction of pressure and / or release of pressure force. The contact profiles of the end faces 39, 40 are arched inwardly in a circular arc in accordance with the horizontal section shown in Figure 8 and the vertical section shown in Figure 9. The rounding diameter of the horizontal curvature of the contact profiles is greater than the rounding diameter of the vertical curvature of the contact profiles. Furthermore, the cross section of the curvature of the contact profiles of the end faces 39, 40 is less than the cross section of the end faces 39, 40 of the pressure element 33, so that the pressure element in the front view of the contact profiles has an outer facing the adjacent components wall. The wall is rounded according to the horizontal section shown in FIG. 8 and the vertical section shown in FIG. Furthermore, the contact profile surfaces of the end faces 39, 40 of the Pressure element 33 made particularly smooth, so that the friction to the concrete of the adjacent components A, B is very low.

Furthermore, the end-side sections 35, 36 on their the middle portion 34 laterally enclosing portions 41, 42 barb-like projections 45 which get caught in the assembly of the pressure element 33 with the thermally insulating body 32, so that the pressure element 33 with the thermally insulating body positively and positively connectable. Conveniently, the barb-like projections 45 are arranged inclined relative to the pressure element 33 so that they favor the insertion of the pressure element in the corresponding recess of the thermally insulating body, but prevent withdrawal. The pressure element 33 is preferably used transversely to its essential axial extent in the thermally insulating body 32, wherein the thermally insulating body 32 is expediently designed for this purpose in several parts.

The end-side sections 35, 36 also each have an expanded cross-section in the form of a protruding portion 43, 44, each of which rests against the thermally insulating body 32 and thus arrests and fixes the pressure element 33 in the thermally insulating body.

Further, the end portion 35 has two webs 46, which act as a transport lock, for example, by the Verbau of the component for thermal insulation to a semi-finished component or prefabricated the webs 46 embed in this, so that the webs 46 can be anchored with these form-fitting manner.

FIG. 12 shows the pressure element 33 from FIGS. 8 to 11 as an exploded view in a perspective plan view. FIG. 12 illustrates in particular once more the cuboid configuration of the middle section 34 as well as the cap-shaped configuration of the end sections 35, 36.

FIG. 13 shows a section of a third embodiment of a component for thermal insulation in a schematic horizontal section, which is illustrated in FIG. 14 in a schematic vertical section of FIG. 13 along the plane AA. The structural element 47 for thermal insulation according to Figure 13 and Figure 14 is between a supported component A and a supporting member B and consists essentially of a thermally insulating body 48 and of reinforcing elements in the form of pressure elements 49 shown in Figures 13 and 14, wherein a plurality of printing elements are arranged perpendicular to the plane of the vertical section of Figure 14 in succession. The thermally insulating body 48 is usually penetrated by the known from the prior art reinforcing elements for receiving the tensile and / or shear forces, was waived their representation to relieve the figure.

The pressure element 49 passes through the thermally insulating body 48 substantially horizontally from component A to component B, wherein it essentially terminates at the side facing the component A with the thermally insulating body and at the side facing the component B by only about 1 millimeter to Protrudes 3 millimeters from the thermally insulating body. The length of the pressure element 49 therefore essentially corresponds to the width or thickness of the thermally insulating body 48. The pressure element 49 is formed mirror-symmetrically in the horizontal transversely to its longitudinal extent and consists of a central portion 50, which preferably consists of a mineral material whose opposite ends to the central portion 50 fixedly connected end portions 51, 52, which are preferably made of plastic, are arranged. The central portion 50 has a substantially rectangular cross-section and is cuboidal. Further, the middle portion 50 on its the end-side sections 51, 52 facing end faces 53, 54 planar contact profile surfaces. The end-side sections 51, 52 are cap-shaped, wherein they enclose the middle section 50 in a form-fitting manner, so that they can be applied and fixed by gluing, plugging and / or pressing on the central section 50.

The end-side sections 51, 52 have at their the component A, B facing end faces 55, 56 curved contact profiles for the introduction of pressure and / or Druckkraftausleitung. The contact profiles of the end faces 55, 56 are arched inwardly in a circular arc in accordance with the horizontal section shown in Figure 13 and the vertical section shown in Figure 14. The rounding diameter of the horizontal curvature of the contact profiles is greater than the rounding diameter of the vertical curvature of the contact profiles. Furthermore, the cross section of the curvature of the contact profiles of the end faces 55, 56 is less than the cross section of the end faces 55, 56 of the pressure element 49, so that the pressure element in the front view of the contact profiles has an outer facing the adjacent components wall. The wall is rounded according to the horizontal section shown in Figure 13 and the vertical section shown in Figure 14. Furthermore, the contact profile surfaces of the end faces 55, 56 of the pressure element 49 are made particularly smooth, so that the friction to the concrete of the adjacent components A, B is very low.

Furthermore, the end-side sections 51, 52 on their the middle portion 50 laterally enclosing portions 57, 58 barb-like projections 60 which get caught in the assembly of the pressure element 49 with the thermally insulating body 48, so that the pressure element 49 with the thermally insulating body positively and positively connectable. Conveniently, the barb-like projections 60 are disposed so inclined to the pressure member 49 that they promote the insertion of the pressure element in the corresponding recess of the thermally insulating body, but prevent withdrawal.

The end section 52 also has an expanded cross section in the form of a protruding portion 59, which acts as a stop on the thermally insulating body 48 and limits the axial insertion of the pressure element 49 in the thermally insulating body.

Furthermore, the end-side section 51 has two webs 61, which act as a transport safety device, for example, by integrating the webs 61 into the semi-finished component or prefabricated component during installation of the component for thermal insulation, so that the webs 61 can be anchored with these in a form-fitting manner.
