Definitions

  • the present invention relates to a connection component for load-bearing, vertical connection of building parts, which has a heat-insulating base body with two opposite contact surfaces for connection to the building parts and at least one inserted into the heat-insulating body and this penetrating from one to the other contact surface pressure element.
  • load-bearing components are often created from reinforced concrete structures.
  • such building parts can be provided with an externally mounted thermal insulation.
  • the floor slab between basement, such as basement or underground car park, and ground floor is often equipped on the basement side with a heat insulation applied to the ceiling.
  • This results in the difficulty that the load-bearing parts of the building, on which the building rests, such as columns and outer walls, in load-bearing manner with the overlying building parts, in particular the floor ceiling must be connected.
  • This is usually achieved by connecting the floor slab monolithically to the supporting pillars and outer walls with continuous reinforcement.
  • thermal bridges which can be eliminated only by a subsequently attached from the outside thermal insulation.
  • the wall element has a pressure-resistant support structure with arranged in the interstices insulating elements.
  • the support structure may for example consist of a lightweight concrete.
  • Such a wall element is used for thermal insulation masonry exterior walls, for example, by being used as a conventional brick as the first stone layer of the supporting outer wall above the basement ceiling.
  • EP 2 405 065 A1 is a pressure force transmitting and insulating connection element known, which is used for the vertical, load-bearing connection of building sections to be created from concrete. It consists of an insulating body with one or more printing elements embedded therein. By the pressure elements transverse shear reinforcement elements extending for connection to the building concrete parts to be created extend substantially vertically beyond the top and bottom of the insulating body.
  • the insulating body can be made of foam glass or expanded polystyrene rigid foam and the pressure elements made of concrete, fiber concrete or fiber plastic, for example.
  • the operating principle of such a heat-insulating connection element with internal pressure elements is thus to reduce the bearing surface between the building parts in order to reduce heat transfer.
  • Such a space-reduced or selective application of force from a horizontal building structure in a vertical building structure carrying these individual printing elements makes high demands on the stability and load-bearing capacity of the printing elements. Due to the design, eccentricities and uneven loads may occur at the contact points between a horizontal building structure and the underlying vertical building structure at the support points. For example, in the case of a concrete floor slab, too little settling and / or elastic deformation may occur due to the load resting on it. This leads to a force redistribution at the support points. If a floor ceiling is supported by a few printing elements, so it can come by such a Auflagerverloomung to overload a printing element.
  • Object of the present invention is therefore to increase in a heat-insulating connection component with inneredem pressure element, the carrying capacity and to avoid a failure due to eccentric introduction of force.
  • the invention provides that on one of the contact surfaces above or below the pressure element, a deformation element is arranged.
  • a deformation element By installing such a deformation element, a rotational ability is achieved between the mutually load-bearing parts of the building, which allows a balance of eccentricities and uneven loads.
  • the most uniform application of force or centering of the force introduction is achieved, which leads to an increase in the carrying capacity of the printing elements.
  • the deformation element is preferably beyond the associated contact surface of the connection component in the vertical direction. In this way, it can be concreted in with the creation of the associated building part in the fresh in-situ concrete and is thus securely held at the articulated connection point between the building part and pressure element.
  • the deformation element into the heat-insulating base body so that the total height of the pressure element and the deformation element corresponds to the height of the base body.
  • the pressure element can thus also be slightly shorter, that is to say shorter than the height of the base body, that is approximately the thickness of the deformation element So only "essentially” penetrate from one to the other contact surface.
  • An inventive deformation element may preferably be made of an elastomer. Such, formed by the deformation element elastomeric bearing allows by elastic deformation balancing occurring during a Auflagerverrectung of the overlying building part of the building movements of the building.
  • the deformation element can be adapted material technically and / or geometrically in such a way that the eccentricities or uneven loads occurring in the case of a permissible contact rotation are compensated for and a centering of the introduction of force is achieved.
  • the material thickness of the deformation element in its edge regions or the edge regions of the overlying or underlying printing element can be made larger than in its center.
  • the deformation element may be concave on its side remote from the associated contact surface of the connection component. Due to the associated rotational ability, centering of the force introduction on the center of the pressure element is effected.
  • the deformation element only needs to have a comparatively small thickness.
  • the height of the deformation element is less than 20%, preferably less than 10% of the height of the pressure element.
  • the thickness of the deformation element is thus less than 2 cm, preferably less than 1 cm. This small strength is sufficient to compensate for the subsidence movements or bearing twist occurring in a building.
  • connection component can have one or more tensile force reinforcement elements projecting beyond the contact surfaces on both sides, in particular reinforcing bars. These allow a connection to the reinforcement the above and below building parts and thus a continuous reinforcement situation between the vertical and horizontal building parts.
  • the tensile reinforcement elements are passed through the pressure element and the deformation element.
  • the or the tensile reinforcement elements can thus be poured in the production of the pressure element made of high-performance concrete in this with and then plugging the deformation element.
  • the resulting assembly of pressure element, deformation element and tensile reinforcement element ensures favorable static properties and allows a safe introduction of the auflastenden load capacity in the underneath vertical building structure.
  • connection component which has a heat-insulating base body with two opposite contact surfaces for connection to the building parts and at least one inserted into the heat-insulating body and this penetrating from one to the other contact surface pressure element .
  • a first, lower of the building parts made of concrete then connected the connection component with its first contact surface to the first part of the building, and finally created above the connection component, the second building part made of concrete.
  • a deformation element is arranged above or below the pressure element of the connection component, which element is embedded in concrete when the associated first or second building part is created.
  • a heat-insulating connection component which are primarily used for the vertical load-bearing connection of supports in the basement area to the overlying building parts, such as a floor slab.
  • a support is understood to mean a vertical part of a building which absorbs and transmits loads mainly in the direction of its longitudinal axis.
  • the DIN standard 1041-1 defines a support as a rod-shaped pressure member whose larger cross-sectional dimension in contrast to a wall does not exceed four times the smaller dimension.
  • the connection components described can also be used for connecting a retaining wall to the overlying building construction, in particular an overlying floor slab.
  • FIG. 1 shows a cuboid base body 1 of heat-insulating material.
  • thermal insulating material is for example a mineral insulation, a wood wool multi-layer insulation, an expanded polystyrene foam (EPS, XPS) or foam glass into consideration.
  • the base body 1 thus consists of non-bearing material and is used for heat decoupling between the underlying and overlying parts of the building.
  • the upper side 1a of the main body 1 serves as a contact surface for a floor to be created thereon.
  • the bottom 1 b serves as a contact surface and completion for a underlying supporting building part such as a support.
  • a pressure element 2 is centrally used, which extends substantially from the upper to the lower contact surface and the Recording of the load-bearing capacity of a floor slab bearing it above and derivation of the load-bearing forces into the support underneath.
  • a deformation element 3 made of an elastic polymer material.
  • the deformation element 3 is disc-shaped and has a circular base area, which corresponds to the shape and size of the base of the underlying pressure element.
  • the pressure element and the deformation element can naturally have an arbitrarily shaped base surface.
  • the deformation element can also have a slightly larger, that is, protruding base surface or also a slightly smaller base surface than the pressure element.
  • FIG. 2 shows in an exploded view of the main body 1, the pressure element 2 inserted therein and the deformation element located above 3.
  • the pressure element 2 consists of high performance concrete with a compressive strength> 50 N / mm 2 , preferably ultra high-strength concrete (UHPC) with a compressive strength of> 150 N / mm 2 .
  • UHPC ultra high-strength concrete
  • the pressure element 2 is thus able to absorb the load on him bearing forces and pass it on to the underlying support.
  • the considerably reduced cross-sectional area of the pressure element 2 compared to the base area of the entire connection component including the heat-insulating base body or compared to the corresponding base area of the underlying support leads to a considerable reduction in the thermal conductivity of the connection component as a whole.
  • a heat transfer between an underlying support and an overlying floor slab is essentially only by the reduced cross-sectional area of the pressure element 2.
  • the insulating base body 1 ensures with its heat-insulating properties for a
  • the elastic deformation element 3 serves to compensate slight movements of the structure, for example due to a bearing rotation of the floor slab under load, and to center the loading forces on the pressure element 2. Thus, a one-sided or off-center loading of the pressure element 2, which could lead to local overload, avoided.
  • the deformation element 3 generates at this point of articulation a certain rotational capability and thus ensures a balance of eccentricities and uneven loading.
  • the top of the deformation element 3 facing the floor slab is approximately concave or conical, ie the deformation element 3 is thicker in its edge areas than in the middle or the material thickness increases continuously from the inside out.
  • the shaping of the deformation element 3 thereby supports the centering of the introduction of force into the pressure element 2.
  • the deformation element 3 can in principle be used both above and below the pressure element 2 or on both sides of the pressure element 2. Preferably, however, the insert above the pressure element 2, since the static hinge point of the connection of support and floor slab is here.
  • FIG. 3 A development of the connection component from FIG. 1 is in FIG. 3 shown.
  • a tensile reinforcement bar 5 is additionally provided, which leads approximately centrally through the pressure element 2 and the deformation element 3 located above.
  • the reinforcing rod 5 consists, at least in the area in which it passes through the pressure element 2, of a metal alloy with the lowest possible thermal conductivity, such as stainless steel. Since stainless steel is relatively expensive compared to normal structural steel, only the central area can of the reinforcing bar 5 are made of stainless steel, while its ends protruding above and below the terminal member may consist of normal structural steel welded thereto. It is also within the scope of the present invention to use a reinforcing bar 5 made of a non-metallic material such as fiber reinforced plastic (GRP).
  • GRP fiber reinforced plastic
  • the reinforcing bar 5 is passed approximately centrally through the pressure element 2, so that the center of the pressure element 2 can continue to serve as a hinge point and can be considered.
  • the arrangement of a plurality of reinforcing bars outside the center axis of the pressure element 2 in the context of the present invention even if this reduces the joint properties created by the deformation element 3 or partially canceled.

  • the reinforcing bar 5 of the connection component runs upward into the concrete floor 4 and down into the concrete pillar 6 and can preferably be connected to the reinforcement 4a of the floor slab 4 and the reinforcement 6a, 6b of the support 6, for example by means of metal wire.
  • a thermal decoupling between support 6 and floor 4 is achieved by the connection component on the one hand, on the other hand, the reinforcement can be passed from the support 6 to the floor slab 4 and thus support 6 and floor slab 4 monolithically connected to each other.
  • connection component 1 can be inserted into the formwork for the pillar 6 to be concreted and connected to its reinforcement structure 6a, 6b. Subsequently, the formwork for the support 6 can be poured through a filling opening, not shown, with fresh concrete and this compacted.
