Definitions

  • the present invention relates to a connection component for the load-bearing, vertical connection of building parts, which has a heat-insulating base body with two opposing contact surfaces for connection to the building parts and at least one pressure element inserted into the heat-insulating base body and penetrating this from one contact surface to the other.
  • load-bearing components are often made from reinforced concrete structures.
  • such parts of the building can be provided with external thermal insulation.
  • the ceiling between the basement, such as the basement or underground car park, and the ground floor is often equipped on the basement side with thermal insulation attached to the ceiling.
  • the difficulty arises here that the load-bearing parts of the building on which the building rests, such as columns and outer walls, have to be connected in a load-bearing manner to the parts of the building located above, in particular the ceiling.
  • This is usually achieved in that the floor slab is monolithically connected to the load-bearing columns and outer walls with continuous reinforcement.
  • this creates thermal bridges that are difficult to remove by adding thermal insulation from the outside.
  • the upper section of the load-bearing concrete columns facing the floor slab is also often sheathed with thermal insulation. This is not only complex and visually less appealing, but also leads to unsatisfactory building physics results and also reduces the parking space available in the underground car park.
  • the wall element has a pressure-resistant support structure with insulating elements arranged in the spaces.
  • the supporting structure can for example consist of a lightweight concrete.
  • Such a wall element is used for the thermal insulation of brick exterior walls, for example by using it like a conventional brick as the first stone layer of the load-bearing exterior wall above the basement ceiling.
  • a component which is provided for connecting a protruding outer part to a floor slab and thus for horizontal installation, is from the WO 2008/113347 A2 known. It comprises a heat-insulating base body and pressure elements penetrating the base body. On their end faces facing the two building parts, these have concave contact profiles which are provided with deformation elements. These form a kind of articulated connection at the pressure introduction point between the pressure element and the building part, which leads to a reduction in the forces acting on the pressure element.
  • a pressure force-transmitting and insulating connection element which is used for the vertical, load-bearing connection of building parts to be made from concrete. It consists of an insulating body with one or more pressure elements embedded in it. Shear force reinforcement elements run through the pressure elements and extend essentially vertically over the top and bottom of the insulation body for connection to the building parts to be constructed from concrete.
  • the insulation body can for example be made of foam glass or expanded polystyrene hard foam and the pressure elements of concrete, fiber concrete or fiber plastic.
  • the functional principle of such a heat-insulating connection element with internal pressure elements is therefore to reduce the contact surface between the building parts in order to reduce heat transfer.
  • a Such area-reduced or punctual introduction of force from a horizontal building structure into a supporting vertical building structure via individual pressure elements places high demands on the stability and load-bearing capacity of the pressure elements. Due to the design, eccentricities and uneven loads can occur at the support points between a horizontal building structure and the underlying vertical building structure. For example, in the case of a concrete floor slab, the load resting on it can lead to slight settlements and / or elastic deformation. This leads to a redistribution of forces at the support points. If a floor slab is supported by a few pressure elements, such a rotation of the support can overload a pressure element.
  • the object of the present invention is therefore to increase the load-bearing capacity of a heat-insulating connection component with an internal pressure element for the load-bearing, vertical connection of building parts and to avoid failure due to eccentric introduction of force.
  • connection component with the features of claim 1 to create a load-transferring, vertical connection of building parts.
  • a connection component of the type mentioned at the beginning is used to create a load-transferring, vertical connection of building parts, in which a deformation element is arranged on one of the contact surfaces above or below the pressure element.
  • a deformation element By installing such a deformation element, a rotation capability is achieved between the building parts that load one another, which enables eccentricities and uneven loads to be compensated for. In this way, the most uniform possible introduction of force or centering of the introduction of force is achieved, which leads to an increase in the load-bearing capacity of the pressure elements.
  • Such a deformation element thus creates an articulated connection between a vertical part of the building and an underlying, load-bearing, vertical building structure created.
  • the deformation element preferably projects beyond the associated contact surface of the connection component in the vertical direction. In this way, it can be concreted into the fresh in-situ concrete when the associated part of the building is being built and is thus held securely at the articulated connection point between the building part and the 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 therefore also be made slightly shorter than the height of the base body, i.e. approximately the thickness of the deformation element, i.e. it can only "essentially” penetrate from one contact surface to the other.
  • a deformation element according to the invention can preferably be made from an elastomer.
  • Such an elastomer bearing formed by the deformation element enables, through elastic deformation, a compensation for the movements of the structure that occur when the part of the building loads over it when the bearing is rotated.
  • the deformation element can be adapted in terms of material technology and / or geometry in such a way that the eccentricities or uneven loads occurring in the event of a permissible support rotation are compensated and the force introduction is centered.
  • the material thickness of the deformation element can be selected to be greater in its edge regions or in the edge regions of the pressure element located above or below than in its center.
  • the deformation element can be concave on its side facing away from the associated contact surface of the connection component. Due to the associated ability to rotate, the introduction of force is centered on the center of the pressure element.
  • 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 less than 2 cm, preferably less than 1 cm. This low strength is sufficient to compensate for the settling movements or bearing rotations that occur in a building.
  • connection component which is particularly suitable for vertical installation and which has one or more tensile force reinforcement elements, in particular reinforcement bars, protruding on both sides beyond the contact surfaces.
  • tensile force reinforcement elements are passed through the pressure element and the deformation element.
  • the tensile force reinforcement element or elements can thus be cast into the pressure element from high-performance concrete when it is produced, and the deformation element can then be attached.
  • the resulting structural unit of pressure element, deformation element and tensile force reinforcement element ensures favorable static properties and enables the load bearing forces to be safely introduced into the vertical building structure below.
  • a first, lower part of the building is made of concrete, then the connecting component with its first contact surface is connected to the first part of the building, and finally the second building part is made of concrete above the connecting component.
  • a deformation element is arranged above or below the pressure element of the connection component, which is concreted in when the associated first or second part of the building is constructed.
  • a heat-insulating connection component which are primarily used for the vertical, load-bearing connection of supports in the basement area to the building parts above, such as a floor ceiling.
  • a column is understood to be a vertical part of a building that receives and transfers loads mainly in the direction of its longitudinal axis.
  • the DIN standard 1041-1 defines a column as a rod-shaped compression member, the larger cross-sectional dimension of which, in contrast to a wall, does not exceed four times the smaller dimension.
  • the connection components described can also be used to connect a supporting wall to the building structure above, in particular an overlying storey ceiling.
  • Figure 1 shows a cuboid base body 1 made of heat-insulating material.
  • a mineral insulation material, a wood wool multilayer insulation material, an expanded polystyrene hard foam (EPS, XPS) or foam glass can be considered as the heat insulating material.
  • the base body 1 thus consists of non-load-bearing material and is used for heat decoupling between the parts of the building below and above.
  • the upper side 1a of the base body 1 serves as a contact surface for a floor slab to be created above it.
  • the underside 1b serves as a contact surface and closure for a load-bearing part of the building located underneath, such as a support.
  • a pressure element 2 is inserted in the middle, which extends essentially from the upper to the lower contact surface and to It is used to absorb the load-bearing forces of a floor slab above it and to transfer the load-bearing forces to the column below.
  • a deformation element 3 made of an elastic polymer material is concealed.
  • the deformation element 3 is disk-shaped and has a circular base, the shape and size of which corresponds to the base of the underlying pressure element.
  • the pressure element and the deformation element can of course have a base area of any shape.
  • the deformation element can also have a slightly larger, that is to say protruding, base area or also a slightly smaller base area than the pressure element.
  • Figure 2 shows in an exploded view the base body 1, the pressure element 2 used in it and the deformation element 3 located above it.
  • 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 bearing forces on it and to pass them on to the support below.
  • a heat transfer between an underlying support and a floor above it takes place essentially only through the reduced cross-sectional area of the pressure element 2.
  • the insulating base body ensures heat decoupling between the building
  • the elastic deformation element 3 serves to compensate for slight movements of the building, for example due to a bearing rotation of the floor slab under load, and to center the load-bearing forces on the pressure element 2. Thus, a one-sided or eccentric loading of the pressure element 2, which could lead to local overload, avoided.
  • the deformation element 3 generates a certain ability to rotate at this articulation point and thus ensures compensation for eccentricities and uneven loading.
  • a relatively thin material thickness of only 1-2 cm in the exemplary embodiment is sufficient for the deformation element 3 for this purpose.
  • greater material thicknesses are also within the scope of the present invention.
  • the upper side of the deformation element 3 facing the floor slab is roughly concave or conical, i.e. the edge areas of the deformation element 3 are thicker than in the middle or the material thickness increases continuously from the inside out.
  • the shape 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. However, it is preferred to use it above the pressure element 2, since this is where the static articulation point of the connection between the support and the floor slab is located.
  • connection component Figure 3 A further development of the connection component Figure 1 is in Figure 3 shown.
  • a tensile force reinforcement bar 5 is also provided, which leads approximately centrally through the pressure element 2 and the deformation element 3 located above it.
  • the reinforcing bar 5 is made of a metal alloy with the lowest possible thermal conductivity, such as stainless steel, at least in the area in which it passes through the pressure element 2. Since stainless steel is relatively expensive compared to normal structural steel, only the central area can be used of the reinforcing bar 5 consist of stainless steel, while its ends pointing above and below the connecting component can consist of normal structural steel welded to it. 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 viewed.
  • the arrangement of several reinforcing bars outside the central axis of the pressure element 2 is also within the scope of the present invention, even if this reduces or partially eliminates the joint properties created by the deformation element 3.
  • connection component In Figure 4 a plan view of the connection component with its insulating base body 1 and the pressure element 2 inserted in the center and the deformation element 3 located above it is shown.
  • the reinforcing bar 5 runs perpendicular to the plane of the drawing Figure 4
  • the cut line CC shown shows the cut for the in the following Figure 5 shown cross-section.

  • the support 6 is provided in a conventional manner with vertical reinforcement 6a, 6b. This consists of several vertical reinforcing bars 6a distributed within the column 6 and reinforcing stirrups 6b placed horizontally around the reinforcing bars 6a.
  • the reinforcing bar 5 of the connection component runs upwards into the concrete floor slab 4 and down into the concreted column 6 and can preferably be connected to the reinforcement 4a of the floor slab 4 or the reinforcement 6a, 6b of the support 6, for example by means of tie wire.
  • thermal decoupling between support 6 and floor 4 is achieved by the connecting component, and on the other hand, the reinforcement can be passed through from support 6 to floor 4 and thus support 6 and floor 4 can be monolithically connected to one another.
  • connection component 1 can be inserted into the formwork for the support 6 to be concreted and connected to its reinforcement structure 6a, 6b.
  • the formwork for the support 6 can then be filled with fresh concrete through a filling opening (not shown) and this can be compacted.
  • the floor slab 4 can be created above the connecting component in a conventional manner.
