Definitions

  • the invention relates to a thermally insulating component of the type specified in the preamble of claim 1.
  • a thermally insulating component that has thrust bearings.
  • the component has U-shaped steel brackets that form shear reinforcement.
  • the U-shaped ends of the steel brackets are each integrated into a thrust bearing and form a prefabricated unit with it.
  • the thrust bearings protrude beyond the insulating body on both long sides of the insulating body and thereby form a heat-conducting connection between the two parts of the building.
  • the DE 195 42 282 A1 and the DE 35 09 890 A1 reveal components for sound insulation. Reinforcing bars that have bends protrude through the components. The concrete of the components to be connected protrudes on the inside of the bends to transmit force.
  • the EP 0 133 875 A1 discloses a thermally insulating component according to the preamble of claim 1.
  • the invention is based on the object of creating a thermally insulating component which has improved thermal insulation properties.
  • the invention provides that the support bearing only protrudes beyond the insulating body on one of the two long sides.
  • the support bearing is therefore at a distance from the other long side. Because the at least one support bearing protrudes beyond the insulating body on only one long side, the heat transfer from the first to the second long side of the insulating body is reduced. This makes it possible to easily achieve improved thermal insulation properties.
  • the support bearing preferably acts as a deflection bearing that deflects the acting vertical transverse force into a horizontal tensile force.
  • the horizontal tensile force is preferably absorbed by a section of the transverse force element anchored in the adjacent part of the building.
  • the thermally insulating component can also bridge a comparatively wide joint between the structural parts and transmit high transverse forces between the structural parts.
  • the at least one support bearing protrudes beyond the insulating body on only one of the two long sides, a constraint-free installation of the thermally insulating component is possible.
  • the shear force element is in particular a shear force bar.
  • the shear force bar is preferably made of steel or fiber-reinforced plastic, in particular carbon fiber-reinforced or glass fiber-reinforced plastic.
  • the shear force bar preferably has a round or square, for example rectangular, cross section.
  • the shear force bar can also be formed by flat steel, in particular a steel strip. By appropriately choosing the cross section of the shear force bar, the transferable Lateral forces can be adjusted.

  • the at least one support bearing preferably consists of pourable or sprayable material.
  • the at least one support bearing can consist of high-strength, in particular ultra-high-strength, concrete or mortar, ceramic or plastic, in particular fiber-reinforced plastic.
  • the compressive strength of the at least one support bearing is preferably greater than the compressive strength of the surrounding concrete.
  • the load-bearing capacity of the thermally insulating component is therefore in particular greater than the load-bearing capacity of a thermally insulating component in which the transverse force element is supported by the surrounding in-situ concrete.
  • At least one support bearing has a contact area with which the support bearing rests on the transverse force element.
  • the support bearing can be arranged adjacent to the transverse force element and can rest on one side of the transverse force element.
  • the transverse force element is at least partially embedded in the support bearing.
  • the contact area advantageously extends over a partial circumference or the entire circumference of the transverse force element.
  • the support bearing advantageously partially, in particular completely, surrounds the transverse force element in the contact area.
  • the contact area is preferably aligned so that the transverse force element can transmit both forces in the vertical direction and forces in the transverse direction of the thermally insulating component to the support bearing.
  • the transverse force element By supporting the transverse force element in the vertical and transverse directions, high transverse forces can be transmitted via the transverse force element.
  • the joint By supporting the transverse force element, the joint can be made comparatively wide, resulting in a good insulating effect.
  • the transmission of forces in both the vertical and transverse directions can be achieved in particular by tilting the contact area towards the vertical and transverse directions.
  • the contact area can also be curved or have several sections that run at an angle to one another in order to allow forces to be transmitted in several directions.

  • the anchoring sections advantageously run in the transverse direction.
  • the middle section is advantageously inclined at 90° to the anchoring sections.
  • the bisector between the middle section and the anchoring section advantageously intersects the support bearing. As a result, forces that act on the transverse force element can be easily introduced into the at least one support bearing.
  • the support bearing has an inside facing the central section and a transverse side facing the anchoring section.
  • the bisector between the middle section and the anchoring section forms an angle with the bisector between the inside and the transverse side of the support bearing, which is preferably smaller than 45°.

  • the thermally insulating component 1 has support bearings 14, transverse force elements 15, tension rods 51 and compression rods 52.
  • a tension rod 51 and a compression rod 52 are each arranged in a common plane 41.
  • a support bearing 14 and a transverse force element 15 are each arranged in a common plane 40.
  • the tension rods 51 and compression rods 52 have a distance s from an adjacent transverse force element 15, which is measured in the longitudinal direction 6 of the thermally insulating component 1.
  • the transverse force element 15 is at a distance t from the next tension rod 51.
  • the distances s and t can be the same size or different sizes.
  • At least one transverse force element 15 and a support bearing 14 arranged thereon can be combined in any suitable manner with other elements for force transmission such as thrust bearings, thrust bearings, tension rods, compression rods and transverse force rods in order to adapt the thermally insulating component 1 to the loads that occur.
  • the transverse force element 15 has a bend 27 arranged in the insulating body 5 and a second bend 27 arranged in the balcony slab 2.
  • the support bearing 14 is supported at the bend 27 in the insulating body 5.
  • the support takes place via the surrounding concrete of the balcony slab 2.
  • the support bearing 14 has a transverse side 29 which rests on the anchoring section 24.
  • the transverse side 29 projects into the concrete of the building ceiling 3.
  • the support bearing 14 also has an inside 19 which faces the middle section 25. In the exemplary embodiment, the inside 19 runs parallel to the vertical direction 8.
  • the inside 19 and the transverse side 29 include an angle bisector 33.
  • the middle section 25 and the anchoring section 24 include an angle bisector 34.
  • the bisectors 33 and 34 enclose an angle ⁇ that is less than 45°, in particular less than 30°.
  • An angle ⁇ of 0° i.e. an embodiment in which the bisectors 33 and 34 coincide in a view in the longitudinal direction 6 of the thermally insulating component 1, can also be advantageous.
  • the cross-sectional area of the support bearing 14 increases from the contact area 21 to the outside 30.
  • the support bearing 14 has a bottom 35 which connects the inside 19 with the outside 30.
  • the underside 35 runs at an angle of more than 90° to the inside 19 and at an angle of less than 90° to the outside 30. This forms the increasing cross-sectional area of the support bearing 14.
  • the middle section 25 encloses an angle ⁇ with the vertical direction 8 that is more than 0 °.
  • the angle ⁇ is approximately 30°.
  • the at least one support bearing 13, 14 and the transverse force element 15 can be combined with any known elements for transmitting forces between the longitudinal sides 9 and 10 of the insulating body 5. Further elements for force transmission are preferably arranged at a distance in the longitudinal direction 6 from the transverse force element 15 with the support bearing pair 16 arranged thereon.
  • all support bearings 13, 14 protrude above the insulating body 5 only on one long side 9, 10 of the insulating body 5 and are at a distance n from the other long side 9, 10 of the insulating body 5.
  • the support bearings 13, 14 can be flush with one long side 9, 10 of the insulating body 5 or can protrude beyond the long side 9, 10 of the insulating body 5.
  • the insulating body 5 can have any structure.
  • the insulating body 5 can be formed by a box which is composed of one or more individual parts and is arranged in the insulating material.
  • the insulating body 5 can also be formed from dimensionally stable thermally insulating material.
  • the angle bisectors 33 and 34 and the angles between the angle bisectors are measured in a section plane perpendicular to the longitudinal direction 6.
  • the angle bisectors 33, 34 are the straight lines that bisect the angle that the specified elements limit.
