Definitions

  • the invention relates to a component for thermal insulation between two components, in particular between a building and a cantilevered outer part, consisting of an insulating body to be laid therebetween with at least integrated pressure elements, which run through in the installed state of the component through the insulating body and in each case can be connected to both components.
  • Such components are installed, for example, between a balcony and the associated floor slab to avoid a cold bridge in this area as far as possible, with reinforcing bars, which are connected to both components, ie a balcony and the floor slab, traversing the insulator, for the necessary transmission the occurring tensile, transverse and compressive forces provide.
  • these reinforcing elements in the joint area are made of stainless steel, which offers sufficient protection against corrosion and, on the other hand, also has good thermal insulation properties.
  • a disadvantage of the stainless steel reinforcing bars but in particular the high cost, especially if - as is the case with the printing elements - to achieve sufficient carrying capacity reinforcing elements must be used with relatively large cross-sections.
  • High-strength concrete can not only be produced in almost any complex shape, but is also characterized by its good thermal insulation properties and also has no corrosion problems. Compared to stainless steel printing elements, printing elements made of high-strength concrete are also comparatively inexpensive to produce.
  • the present invention has the object to provide a device for thermal insulation of the type mentioned above, which is characterized by even better performance characteristics and in particular by better thermal insulation properties.
  • the pressure elements are made of thermal insulation material.
  • the thermal conductivity A is preferably less than 0.20 W / mK and in particular less than 0.15 W / mK and preferably of the order of 0.13 W / mK or less.
  • the preferred compressive strength f is more than 5 N / mm 2 and in particular more than 7 N / mm 2 and is preferably of the order of 10 N / mm 2 or more to a maximum of 25 N / mm 2 .
  • damping material not only can meet the pressure element existing requirements in terms of compressive strength, but also achieve thermal conductivity values that are otherwise known only from thermal insulation materials that are used without static or dynamic tasks.
  • the described polymer compound compared to lightweight concrete, for example, about a factor of 3 better insulation effect.
  • the pressure element according to the invention also has an E-modulus of more than 100 N / mm 2 and in particular of more than 300 N / mm 2 and preferably of the order of 400 N / mm 2 or more, based on a maximum compression of 3%.
  • the maximum creepage at maximum continuous load is preferably about 3% in such insulating materials and / or has an elongation at break of more than 5% and in particular of the order of about 10%, which at least comes close to the parameters of conventional pressure elements.
  • the insulating material consists of a rigid foam with the properties mentioned and can be brought into the respective desired shape by lost forms or processing of the cured foamed material.
  • the insulating body usually used for thermal insulation of such components completely from the pressure-resistant thermal insulation material according to the invention.
  • the existing of the same material pressure element would be an integral part of the insulator and could either be integrally formed with the rest Isoller stressesmaterial or as a separate component.
  • the pressure elements on their faces facing the components have flat contact profiles, which may be curved arcuate either parallel to the longitudinal extent of the insulating body or in horizontal section, where they then with their curved area expediently protrude into the components.
  • the pressure elements may have on their faces facing the components a sliding layer with reduced compared to the insulating material of the pressure elements friction coefficient, the sliding layer consist of a coating of the pressure element and / or the adjacent component or be formed of a separate sliding element can, which can be arranged adjacent to the contact profiles of the pressure element.
  • an insulating material available that can be used in a device for thermal insulation is provided by the present invention.
  • This insulating material is characterized by the features listed in claim 11 and in this case has a compressive strength f of more than 5 N / mm 2 and in particular of more than 7 N / mm 2 and preferably in the order of 10 N / mm 2 or more preferred up to a maximum of 25 N / mm 2 and serves to transfer force and / or torque.
  • the thermal insulation material has a maximum compression of 0.3% and / or a thermal conductivity ⁇ of less than 0.20 W / mK and in particular less than 0.15 W / mK and preferably of the order of 0 , 13 W / mK or less.
  • thermo insulation material in a structural element for thermal insulation between two components in particular between a building and a cantilevered outer part according to at least one of claims 1 to 10 is used and acts as an integrated pressure element.
  • FIGS. 1 . 2 and 3 is a component 1 shown for thermal insulation, consisting of a between two components (in FIG. 1 Inscribed with “A” and “B") insulator 2 to be arranged as well as Switzerlandkraftbewehrungs instituten 3, transverse force reinforcement elements 4 and compressive force elements 5 consists. While the insulating body 2 conventionally made of a cuboidal polystyrene material, the tensile reinforcing members 3 made of a conventional steel rod, and the transverse force reinforcing members 4 have no substantial changes from the prior art designs, it is in FIG. 1 illustrated compression force reinforcement element 5 according to the invention made of a thermal insulation material and formed in the form of a rigid foam. Like from the FIGS. 1 .
  • each compression force reinforcing element 5 has a cylindrical shape with a horizontal cylinder axis, but the front ends, the so-called contact profiles are crowned, ie each convexly curved with a curvature in vertical and horizontal direction, which has a circular arc shape.
  • these spherical end faces consist of a spherical segment-like surface.
  • the frontal contact profiles 5a, 5b are provided with adapted to the curved surface of the contact profiles cover caps 6, 7, which serve for even force application as well as take over the function of a sliding layer and thus ensure that the compression force reinforcement elements 5 in sliding contact the concrete components A, concerns.
  • FIGS. 4 and 5 show an alternative embodiment of a thermal insulation element 11, in which those components which are identical to the embodiment of the device 11 from the FIGS. 1 to 3 are taken over, are provided with the same reference numerals.
  • the device 11 from the FIGS. 4 and 5 differs from the embodiment of the device 1 from the FIGS. 1 to 3 by an alternative embodiment of a compressive force reinforcement element 15:
  • This is rectangular in shape with flat end faces 15a, 15b, which extend in alignment with the outer sides 2a, 2b of the insulating body and are also provided with cover caps 16, 17, which act as force distribution plates and sliding layer.
  • cover caps 16, 17, which act as force distribution plates and sliding layer.
  • FIGS. 6 and 7 show a total of another embodiment of a device for thermal insulation 21,
  • a cuboid insulating body 2 is provided, which is penetrated by extending horizontally Switzerlandbewehrungs instituten 3.
  • the transverse force reinforcing elements 4 present in the structural elements 1 and 11 are omitted by providing a compressive force reinforcing element 25 which performs the tasks of the transverse force reinforcing elements by it has frontal step-shaped projections 28, 29 which protrude into the adjacent concrete components A, B and are anchored in these for the application of lateral force.
  • the end faces 25a, 25b are also here provided with correspondingly step-shaped cover caps 26, 27 which abut surface on the end faces of the pressure force reinforcement element 25.
  • the transverse force is thus introduced in the projection 29 on the side of the supported component B, ie in particular a balcony slab, in which case the projection 29 protrudes in the lower region of the compression force reinforcement element 25; in contrast, the second protrusion 28 is disposed on the side of the supporting member A at the upper portion of the pressing force reinforcing member 25.
  • This results in a pressure force transmission direction which corresponds approximately to the inclined course of the conventional transverse force reinforcement elements 4, which in the FIGS. 1 to 5 are shown.
  • the compressive force reinforcing element consists of thermal insulation material which has sufficient compressive strength, a modulus of elasticity and sufficient ductility to be used as compression force reinforcing element.
  • thermal insulation material according to the invention which has the characteristic values described above, it can be used not only as a compressive force reinforcing element in the thermal insulation components described here, but also in other places where similar functions have to be fulfilled. namely, for example, for shear reinforcement elements or shear force transmission, as used for example in structural engineering in the support near area of concrete slabs that must be secured against punching.
