Definitions

  • the invention relates to a building with a thermally insulating component.
  • thermally insulating components between adjacent building parts in order to achieve improved thermal insulation.
  • Such thermally insulating building elements can be arranged in the vertical direction between a wall or column and a ceiling or foundation.
  • thermally insulating components that are designed in the manner of bricks.
  • Thermally insulating components are also known which are intended to be arranged between horizontally adjacent parts of the building. Such heat-insulating components are used, for example, to connect projecting structural parts such as balconies or the like. Such a thermally insulating component is, for example, from EP 1 892 344 A1 known.
  • the present invention is based on the object of specifying a building that has an advantageous structure.
  • this object is achieved by a building having the features of claim 1, by a building having the features of claim 6 or by a building having the features of claim 12.
  • thermally insulating components can be used for connecting and thermally separating building parts lying vertically one above the other, the structure of which is similar to the structure of thermally insulating components which are used for connecting horizontally adjacent building parts.
  • This has the advantage that it is only necessary to adapt the thermally insulating components previously used for the horizontal installation position.
  • force-transmitting elements that have hitherto been used exclusively for the horizontal installation position, in particular compression thrust bearings, can be used to connect a wall or support to a ceiling or a foundation.
  • the insulating body which was previously used exclusively for connecting horizontally adjacent components, can also be used in an adapted design.
  • a thermally insulating component previously provided for the connection of horizontally adjacent components can be used without modification for the connection of a wall or support to a ceiling or a foundation.
  • the thermally insulating component has force-transmitting elements which protrude through the insulating body at least from the first longitudinal side to the second longitudinal side.
  • the force-transmitting elements can end on the longitudinal sides of the insulating body or can project upwards and/or downwards beyond the longitudinal sides into the adjoining parts of the building.
  • At least one first force-transmitting element advantageously consists of castable, non-metallic material and is designed as a thrust bearing.
  • the thrust bearing is for the transmission of vertically directed compressive forces and for Transmission of transverse forces directed horizontally and perpendicularly to the longitudinal direction of the insulation joint.
  • transverse forces can, for example, be forces acting on a wall in a horizontal direction, such as wind forces or the like.
  • Such pressure shear bearings are easily available since they are already used for the connection of cantilevered parts of the building such as balconies or the like.
  • the design of special force-transmitting elements for installation between superimposed building parts can be omitted.
  • the pressure thrust bearing advantageously has at least one projection which protrudes into the adjoining part of the structure over a longitudinal side and has a pressure surface for absorbing the transverse forces, the pressure surface being at a distance of at least from the end face of the insulating body, from the side of which a transverse force to be absorbed by this pressure surface acts one third of the width of the insulator.
  • the width of the insulating body is measured in the transverse direction of the insulating joint and horizontally. Since the pressure surface is at a distance of at least one third of the width of the insulating body from the end face of the insulating body from which the transverse force to be absorbed acts, the pressure surface is sufficiently covered with concrete by the adjoining part of the structure. This enables the shear force to be absorbed to be safely introduced and prevents the concrete of the adjacent part of the structure from breaking out at the pressure surface.
  • the pressure surface is inclined to the horizontal to absorb the lateral forces.
  • the pressure surface preferably encloses an angle of at least 20°, in particular of at least 30°, with the horizontal at every point. Accordingly, only the area that encloses an angle of at least 20°, in particular of at least 30°, with the horizontal is advantageously regarded as the pressure surface.
  • Adjoining areas of the pressure thrust bearing that enclose an angle of less than 20°, in particular less than 30°, with the horizontal, ie run comparatively flat, are preferably not regarded as part of the pressure surface.
  • the width of the projection is advantageously at most 40% of the width of the thrust bearing.
  • the width of the projection and the width of the pressure shear bearing are measured horizontally and in the transverse direction of the insulating joint. Accordingly, the projection extends over less than half the width of the thrust bearing. As a result, a sufficient distance from the opposite end face of the insulating body can be achieved in a simple manner.
  • the length of the projection is advantageously at most twice the width of the projection.
  • the length of the projection is measured in the longitudinal direction of the insulation joint.
  • the width of the projection is measured in the transverse direction of the insulation joint and horizontally.
  • the projection preferably has a relatively compact shape and not an elongated shape.
  • the pressure shear bearing is advantageously arranged centrally in the insulating body in the transverse direction of the insulating joint.
  • the insulating body advantageously has opposite end faces which run parallel to the longitudinal direction of the insulating joint.
  • the pressure thrust bearing is advantageously arranged centrally between the end faces of the insulating body.
  • An independent inventive idea relates to the design of the insulating body.
  • the design of the insulating body is independent of the design of the first force-transmitting element as a pressure thrust bearing, which is designed to transmit transverse forces directed horizontally and perpendicularly to the longitudinal direction of the insulating joint.
  • the insulating body be designed as a storage box filled with insulating material.
  • Such storage boxes filled with insulating material are known as insulating bodies for the connection of projecting components such as balconies, ie for arrangement between horizontally adjacent building parts. It has now been shown that storage boxes filled with insulating material are advantageous as insulating bodies for the arrangement can be used in an insulating joint where the adjacent building parts run above and below the insulating joint. As a result, no other insulating bodies are required for the connection of building parts lying above and below an insulating joint than for the connection of building parts lying on both sides next to an insulating joint.
  • the storage box is made of plastic and the insulating material is mineral wool.
  • the at least one first force-transmitting element is preferably positioned in the storage box. All force-transmitting elements of the thermally insulating component are advantageously positioned in the storage box. As a result, the force-transmitting elements are pre-positioned and held over the storage box during assembly of the thermally insulating component, so that the thermally insulating component can be easily installed.
  • At least one first force-transmitting element is advantageously a thrust bearing.
  • the at least one pressure bearing is arranged centrally in the insulating body in relation to the transverse direction of the insulating joint.
  • the thermally insulating component includes both at least one thrust bearing and at least one thrust bearing.
  • At least one pressure shear bearing can be designed to absorb transverse forces directed horizontally and perpendicularly to the longitudinal direction of the insulating joint.
  • At least one pressure shear bearing or alternatively all pressure shear bearings is designed to absorb horizontal forces acting in the longitudinal direction of the insulating joint.
  • a pressure shear bearing designed to absorb transverse forces directed horizontally and perpendicularly to the longitudinal direction of the insulating joint is required at an angle of 90° around the vertical axis rotated orientation provided.
  • all pressure shear bearings of the component are identical, but arranged differently, so that forces can be absorbed in the longitudinal direction of the insulating joint and forces transverse to the longitudinal direction of the insulating joint and in the horizontal direction.
  • the castable, non-metallic material of the at least one first force-transmitting element is advantageously high-strength concrete or high-strength mortar.
  • the castable non-metallic material is ultra high performance concrete or mortar.
  • the castable, non-metallic material is fiber-reinforced.
  • the fibers can be metal fibers or carbon fibers, for example. A fiber reinforcement made of other materials can also be advantageous.
  • At least one further force-transmitting element is advantageously a tension rod.
  • at least one further force-transmitting element is a transverse force bar.
  • Shear force bars arranged in pairs and crossing one another when viewed in the longitudinal direction of the insulating joint are particularly preferred. Because the shear force bars cross, shear forces can be transferred in both directions.
  • the at least one tension bar and/or the at least one transverse force bar can consist of steel or fiber-reinforced material, in particular carbon-fiber-reinforced plastic, for example.
  • a further, independent inventive idea relates to the design of at least one force-transmitting element by means of two tension rods, which are connected to one another in a force-transmitting manner via a thrust plate which is at least partially arranged in the insulating body.
  • This configuration of a force-transmitting element is independent of the configuration of further force-transmitting elements, in particular independent of the configuration of further force-transmitting elements for the transmission of compressive forces and/or transverse forces.
  • a force-transmitting element consisting of two tension rods, which are connected to one another in a force-transmitting manner via a shear plate, allows both tensile forces and transverse forces to be transmitted via the insulating joint. Due to the small cross-section of the thrust plate, there is a good insulating effect.
  • the force-transmitting element consisting of two tension rods and a thrust plate, also has a simple structure.
  • the tension rods are preferably arranged on opposite high edges of the thrust plate.
  • the thickness of the thrust plate measured in the longitudinal direction of the insulating joint is preferably smaller than the diameter of at least one tension rod. This allows a good insulating effect to be achieved.
  • the insulating body of the thermally insulating component is preferably elongate and has a significantly greater length than conventional masonry blocks. This is particularly useful when connecting a wall to a ceiling or foundation. As a result, the number of thermally insulating components required over the length of the wall can be kept low.
  • the length of the insulating body measured in the longitudinal direction of the insulating joint is advantageously at least 5 times the height of the insulating body.
  • the height of the insulating body is measured from the first long side to the second long side in the vertical direction.
  • the length of the insulating body measured in the longitudinal direction of the insulating joint advantageously corresponds to the length of the thermally insulating component measured in the longitudinal direction of the insulating joint.
  • the length of the insulating body measured in the longitudinal direction of the insulating joint is at least 5 times the width of the insulating body measured horizontally and in the transverse direction of the insulating joint.
  • Thermally insulating components can also be used to connect a support, the insulating body of which has a length which approximately corresponds to the width of the insulating body.
  • the length of the insulating body can be used to connect a support for example be a third to 3 times the width of the insulating body.
  • All force-transmitting elements of the thermally insulating component are advantageously formed separately from one another and separated from one another by the insulating body.
  • the compression thrust bearing and compression bearing of tension rods and shear force rods are designed separately.
  • the tension rods and transverse force rods are advantageously at a distance from the pressure bearings and/or pressure shear bearings in the longitudinal direction of the insulating joint.
  • the first building part 2 can be a wall or a column.
  • the second building part 3 can also be a wall or support.

  • the first structural part 2 and the second structural part 3 are aligned vertically, and the first structural part 2 is arranged above the second structural part 3 .

  • the building parts 2 and 3 are connected to one another via a thermally insulating component 6 .
