Definitions
- the invention relates to a component system for thermal insulation, consisting of components for thermal insulation, wherein the components for thermal insulation between two components to be concreted, in particular between a supported component and a load-bearing component of a building, and at least to be arranged therebetween a thermally insulating body with integrated Printing elements, wherein the pressure elements are used in the components for thermal insulation and part of the components, and integrated tensile bars and transverse force rods consist essentially transverse to the longitudinal extent of the thermally insulating body traverses this and are connectable to both components, wherein the transverse force bars in parallel Vertical planes through the thermally insulating body inclined, wherein the components for thermal insulation for different load cases are elementalized by the proportion and / or the number the reinforcing elements in the thermal insulation components varies.
- Such component systems for thermal insulation and their components for thermal insulation are known in the relevant prior art, for example from DE 29707378 U1 or EP 0834622 B1, in many different versions.
- two components in particular a supported outer component, such as a cantilevered balcony plate, and located in the thermally insulating building interior supporting inner component, such as a ceiling plate, thermally decoupled from each other to reduce the thermal bridge in this area, but also at the same time statically connected to each other ,
- This static connection takes place via reinforcing elements, in particular pressure elements, tensile bars and transverse force bars, which extend through a thermally insulating body, commonly referred to as insulation body or insulator, extend and embed in the adjacent components.
- the reinforcing elements transmit the through the supported component occurring loads, in particular pressure, tensile and shear forces on the supporting component.
- the known component systems for thermal insulation consist of components for thermal insulation, which have different dimensions and different reinforcement proportions.
- the reinforcing elements of the reinforcement elements are defined by their length and their circumference, therefore by their volume and by their number. Since the loads caused by the supported component on the thermal insulation component change depending on the embodiment of the supported component, the proportions of the reinforcement elements necessary for the transmission of the loads vary.
- the component systems for thermal insulation therefore consist of components for thermal insulation which are designed and disposed for different load cases and thus for different levels of stress.
- the components for thermal insulation are divided into different load groups, which is characterized by the maximum absorbable load of the integrated reinforcing elements and their number or proportions.
- the components therefore have a defined number or proportion of tensile bars, transverse force bars and pressure elements, wherein the number or proportion of transverse force bars within the load group is variable, since the reinforcing elements of the components are designed and instituted for thermal insulation, that the design value of the absorbable tensile force of the tensile bars essentially corresponds to the rated value of the compressible compressive force of the pressure elements or for strongly over-sized pressure elements that the design value of the absorbable tensile force of Switzerlandkraftstäbe corresponds to the design value of the maximum compressive force acting on the pressure elements, resulting from the recordable loads of Component for thermal insulation results.
- the tensile bars are so over-measured that for the connection of the components for thermal insulation of the respective adjacent component, the required connection reinforcement only on the number or proportion of Tensile bars is tuned.
- the number or the proportion of shear bars is not taken into account due to the over-dimensioning of the tensile bars.
- the tensile bars consist of a material whose thermal insulating properties are substantially lower than those of the thermally insulating body they pass through, the over-dimensioning of the tensile bars results in an unnecessary deterioration of the thermally insulating function of the thermal insulation elements. It is therefore not surprising that the known embodiments of components for thermal insulation only have insufficient thermal protection, which often just barely meets the minimum heat protection and thus should only prevent structural damage. Due to the poor thermal insulation properties of the known components, these therefore form heat or cold bridges even when installed, which should be reduced to a minimum, especially by the use of the components for thermal insulation in the field of use. There is therefore no sufficient thermal separation between the outer and inner components or between the supported and the supporting components.
- the present invention seeks to propose a component system for thermal insulation, the components for thermal insulation are characterized by very good thermal insulation properties, so that the respective component is suitable for use in passive houses, at the same time a material and weight saving should be made, thereby facilitating transportation and improving handling.
- the components of the device system should be inexpensive to manufacture.
- the proportion and / or the number of tensile bars of the respective component for thermal insulation is designed and instituted so that the design value of the absorbable tensile force of Switzerlandkraftstäbe to the extent of introducing into the adjacent bearing component tensile force, the from the design value of the absorbable tensile force of at least one transverse force rod and its inclination angle is smaller than the design value of the maximum compressive force acting on the pressure elements, resulting from the recordable loads of the component for thermal insulation, wherein the components are divided into thermal load groups and wherein Within a load group with essentially the same proportion and / or number of tensile bars, the proportion and / or the number of pressure elements changes with the change in the proportion and / or the number of lateral force bars or within a Bela tion group at substantially constant proportion and / or number of printing elements changes with the change in the proportion and / or the number of lateral force rods, the proportion and / or the number of tensile bars.
- the design value of the absorbable tensile force of the tensile bars is smaller than the tensile force which can be induced by the tensile and transverse force bars by the amount of tensile force which can be introduced into the adjacent structural component resulting from the design value of the absorbable tensile force of at least one transverse force rod and its inclination angle in the supporting component, which results from the recordable loads of the component for thermal insulation.
- the reinforcing elements are matched to one another so that an over-dimensioning of the tensile bars is largely avoided.
- the design value of the absorbable tensile force of the tensile bars is smaller than that of the tensile and tensile forces by the amount of tensile force which can be introduced into the adjacent structural element resulting from the design value of the absorbable tensile force of the transverse force bars and the angle of inclination of the transverse force bars
- Transverse force rods introduced tensile force in the load-bearing component, which results from the recordable loads of the component for thermal insulation.
- the component system for thermal insulation consists of components for thermal insulation designed and instituted for different load cases and thus for different levels of stress.
- the components for thermal insulation are therefore divided into different load groups, which is characterized by the maximum absorbable load of the integrated reinforcing elements and their number or proportions.
- the load groups can be classified according to the number or the proportion of tensile bars, the number or proportion of shear bars, the number or proportion of pressure elements or a combination thereof. The most useful, however, is the classification of the load groups according to the number or proportion of tensile bars or according to the number or proportion of pressure elements.
- the components for thermal insulation within a load group have a fixed number or a fixed proportion of tensile bars, the number or proportion of the transverse force bars and the pressure elements within the Load group is variable, whereby the device for thermal insulation can be optimally adapted to the loads to be transmitted and over-dimensioning of the reinforcing elements, in particular the tensile bars, is largely avoided.
- the proportion and / or the number of printing elements changes with the change in the proportion and / or the number of transverse force rods when the proportion and / or number of tensile force bars is substantially the same.
- the classification of the stress groups is based on the number or the proportion of pressure elements, then the components for thermal insulation within a load group have a fixed number or a fixed proportion of pressure elements, the number or the proportion of the transverse force rods and the tensile force rods within the Load group is variable. Thus, over-dimensioning of the reinforcement elements is largely avoided. As a result of this arrangement, the proportion and / or the number of tensile bars changes with the change in the proportion and / or the number of transverse force bars when the proportion and / or number of pressure elements are substantially the same.
- the tensile and transverse force rods are now optimally utilized, it is necessary that for the connection of the components for thermal insulation of the respective adjacent component, the tensile and transverse force bars are matched with the connection reinforcement, the tensile and transverse force rods with the in the respective adjacent component integrated connection reinforcement are directly in operative connection.
- This operative connection is ensured in its simplest form by a lap joint.
- the tensile and transverse force rods therefore extend so far into the adjacent component until they overlap with the connection reinforcement of the adjacent component.
- the connection reinforcement is in the same plane as the tensile and transverse force rods, so that a so-called one-level impact is formed.
- the tensile and transverse force rods can also be used with other anchoring variants known from the prior art, e.g. with socket joints, anchored in the adjacent components.
- the present invention has the advantage that the number or proportion of reinforcing elements in the components for thermal insulation of the component system for thermal insulation is reduced to the necessary level, which is why the material requirements for the reinforcing elements, compared to the prior art, considerably reduced. Since the reinforcing elements consist of a material whose thermal insulating properties are substantially lower than those of the thermally insulating body they pass through, the reduction of the material requirement for the reinforcing elements results in an improvement of the thermally insulating function of the respective component for thermal insulation, so that the respective component for thermal insulation for use in Niedrigstenergie Reifenn, in particular passive houses, is suitable. In addition, the material savings for a cost savings and a lower weight of the components for thermal insulation, which facilitates their transport and improves handling.

- thermal insulation component in the illustrated figure 1 is shown only schematically.
- the device for thermal insulation is therefore not with all its individual parts, such as cover or any fire protection element, as well as with all its known from the prior art embodiments, which relates to the different design of the reinforcing elements in the thermally insulating body, shown as these with the present invention have nothing to do and are prior art.
- Figure 1 shows a device 1 for thermal insulation of a component system for thermal insulation in a schematic perspective view, which is arranged between a supported component A, in particular a cantilever balcony plate, and a supporting member B, in particular a ceiling plate.
- the structural element 1 for thermal insulation consists essentially of a thermally insulating body 2 and of a plurality of reinforcing elements in the form of tensile bars 3, transverse force bars 4 and pressure elements 5.
- the tensile bars 3 and the pressure elements 5 traverse the thermally insulating body 2 transversely to the substantially longitudinal extent of the thermal insulating body 2 of component A to component B, wherein they extend in the horizontal direction.
- the transverse force rods 4 also traverse the thermally insulating body 2 transversely to the substantially longitudinal extent of the thermally insulating body 2 from component A to component B, but they cross the thermally insulating body 2 in vertical planes parallel to one another and bend laterally of the thermally insulating body 2 are that they protrude at different heights horizontally from the thermally insulating body 2.
- the reinforcing elements 3, 4, 5 are arranged in a grid pattern, wherein the proportion and / or the number of tensile bars 3 of the component 1 for thermal insulation is designed and instituted so that the design value of the absorbable tensile force F z , Rd of the tensile bars 3 by the extent of tensile force F Q z , R d which can be introduced into the adjacent bearing component B and which results from the design value of the absorbable tensile force F QiRd of at least one transverse force rod 4 and its inclination angle, is smaller than the design value of the maximum acting pressure force F D Ed on the pressure elements 5 which results from the recordable loads of the component 1 for thermal insulation.
