Definitions

  • the invention relates to a component for thermal insulation between two components to be concreted, in particular between a building and a cantilevered outer part, consisting of an insulating body to be laid between them with at least integrated pressure elements which run transversely to the longitudinal extent of the insulating body and are connected to both components are.
  • the pressure elements generally have pressure plates anchored at their ends in the concrete components, which promote the introduction of force into the pressure elements and reduce the anchoring length in the concrete.
  • Such pressure plates which are in particular disc-shaped and arranged parallel to the longitudinal extension of the insulating body and perpendicular to the pressure elements running through the insulating body, have the disadvantage, however, that through them the central axis the pressure elements cannot be arranged at any depth in the thermal insulation component.
  • the height offset between the central axis of the pressure elements and the underside of the pressure plate cannot be reduced to a greater extent while maintaining the pressure plate function and, on the other hand, a certain concrete or insulating body thickness must be maintained below the pressure bearing in order to protect the pressure plate and thus the corrosion-prone pressure element from corrosion to protect.
  • the pressure elements consist of a profile body with several, in particular, vertically extending pressure webs, the length of the pressure elements in the direction of the longitudinal extension of the insulating body, i.e. the length of the system on the adjacent concrete component, being a multiple of its vertical height. While the vertical and horizontal dimensions in the plane of the joint generally do not differ in the case of the printing elements of the prior art, since these are rotationally symmetrical are carried out, the pressure element of the present invention is characterized in that there is only one orientation of the pressure element within the thermal insulation element that meets the requirements for the pressure element.
  • the pressure element according to the invention is due to the vertical, mutually parallel pressure bars in the vertical direction stiff and therefore kink-resistant, on the other hand in the horizontal direction smooth thrust, whereby it does not hinder lateral temperature-related changes in length of the projecting outer part relative to the building. If the pressure element was incorrectly rotated by 90 °, only a fraction of the pressure forces could be absorbed over a longer period of time.
  • the pressure element is optimally designed for the requirements that exist for each of the different stress directions within the joint by adapting the dimension of the pressure bars depending on the direction. This leads to drastic material savings.
  • the provision of several pressure bars means that the height of each pressure bar can be reduced, since the load to be absorbed is distributed accordingly.
  • the vertical direction of the pressure webs means that, although the entire pressure element extends horizontally from one component and thus transversely to the longitudinal extent of the joint to the other component, the pressure webs are at least partially arranged vertically within this horizontally extending pressure element.
  • the pressure webs are expediently connected by at least one connecting web running transversely thereto, which runs either vertically or horizontally in the direction of the longitudinal extent of the insulating body and causes the pressure webs to be mutually fixed in position.
  • this mutual positional fixation can also be ensured by the insulating body itself, so that a connecting web would not be necessary and the individual pressure webs would be loosely arranged without a direct connection.
  • the profile body consists of at least three pressure bars and the length of the pressure elements is at least three times as large as their height, which results in a good relationship between the cross section or the pressure element height and the pressure resistance or the absorbable moment for each pressure element.
  • the webs advantageously extend exactly in the vertical direction through the insulating body in order to ensure the requirement of vertical rigidity and horizontal thrust softness. With certain configurations of the pressure bars, however, their inclination from the vertical can also be recommended, which should not exceed 45 ° in some areas.
  • the pressure bars are provided with recesses penetrating them in the region of the insulating body.
  • the pressure elements on the sides facing the concrete component parallel have plate-shaped contact profiles which extend to the longitudinal direction of the insulating body and which can expediently simultaneously replace the connecting web by connecting the pressure webs to one another.
  • the contact profile surfaces which serve to absorb the pressure forces, are dimensioned essentially as large as the cross-sectional area of the pressure element circumscribed by the pressure webs, so that at least the vertical extension of the pressure element is not increased by the contact profiles. In this way, the distance of the contact profile from the lower edge of the insulating body can be minimized and, due to the larger lever arm between pressure and tension elements, the torque to be recorded can be increased.
  • the plate-shaped design of the contact profiles also includes, in particular, rough, ribbed or generally provided with projections, which improve the contact with the adjacent concrete components.
  • the plate-shaped contact profile can be made flatter and therefore wider, since it is supported on its rear side at short intervals by the pressure webs running perpendicular to it and is secured against bending. Consequently, the contact profile does not have to have a vertical projection over the pressure webs, which are also reduced in height, with the same force absorption.
  • the lamellar structure of the pressure elements means that the plate-shaped thrust bearings do not have to be made larger than the cross-sectional area circumscribed by the pressure bars, and yet the bearing surface is made larger than the cross-sectional area of the web in the insulating body, so that the thrust bearing performs its function of introducing the pressure forces into the Can guarantee pressure element.
  • the contact profiles are positively connected to the adjacent concrete components, which can be done by individual projections extending into the concrete, a correspondingly designed surface or by a contact profile extending into the concrete component.
  • the horizontal thrust movements between the two components are transmitted directly to the pressure element, which according to the invention is designed to be thrust-smooth. Relative movements between the concrete components and the pressure element, which can lead to overstressing of the thrust bearing surface up to its destruction, can thus be prevented.
  • the contact profiles are at least partially embedded in the insulating body and protrude only slightly into the concrete component in order to maintain a sufficient distance from the reinforcement in the concrete component.
  • the pressure elements and not only the contact profiles can, in general, protrude at least partially beyond the insulating body and be anchored in the adjacent concrete component, in order to produce a positive connection, which in particular favors the transmission of horizontal movements.
  • the pressure elements consist of, in particular, alkali-resistant, fiber-reinforced plastic, for example of glass fiber-reinforced thermoplastics or thermosets, since this results in less heat conduction through the insulating body.
  • a plastic pressure element does not need a concrete or insulating material cover, since it is not sensitive to corrosion. Rather, the plastic pressure element can be installed flush with the adjacent concrete components, which improves handling.
  • a simplification in the assembly of the component for thermal insulation and a reduction in processing costs results from the fact that the length of the pressure element can correspond to the length of the insulating body and thus only one pressure element with a correspondingly large number of pressure bars has to be provided per insulating body.
  • the pressure elements can be composed in a modular design from individual pressure bars and / or contact profiles, or individual pressure elements can be combined to form a composite pressure element that is variable in length.
  • the combination can take place via a connecting web or via suitable connecting means, in particular by mutual gluing, clipping on or latching.
  • a pressure element 1 is shown in plan view, which extends between a building part A and a projecting outer part B, for example a concrete slab.
  • the pressure element 1 consists of eight vertical pressure bars 2, at the ends of which a plate-shaped contact profile 3 or 4 extending perpendicular to the pressure bars is arranged.
  • the contact profile 3 lies flat against the balcony plate B for transferring the compressive forces, while the contact profile 4 is connected flatly to the building component A.
  • Any means for positively anchoring the contact profiles in the concrete components - for example in the form of projections - are not shown in the principle drawings for the sake of simplicity.
  • an insulating body 5 is also arranged in the joint between the building component A and the balcony slab B, which extends along the entire length Joint extends and only has recesses for the tensile, transverse force and pressure elements to be introduced.
  • the insulating body also extends above the pressure element 1 in the joint in order to prevent sound and heat transmission through the joint. It can also be seen from the sectional view in FIG. 2 that the length of the pressure element 1 in the direction of the longitudinal extent of the insulating body is a multiple of its vertical height, namely twice in the present case.
  • Figure 3 finally shows the pressure element 1 in side view and shows the arrangement of the pressure element within the joint between the two concrete components.
  • the pressure element can be installed in the lowest possible position within the joint, since in particular the two plate-shaped contact profiles 3 and 4 do not protrude downward relative to the pressure webs 2.
  • the pressure element 1 is made of plastic, it is also not subject to corrosion if it is arranged flush with the underside of the component in the joint and is thus exposed to the ambient climate.
  • the contact profiles 3 and 4 are flush with the two concrete components A and B. Likewise, however, these can also be anchored in the concrete parts by means of projections or extend partially or completely into these concrete components.
  • Figures 4 to 6 show a pressure element 11, which is constructed similarly to the pressure element 1, but has two additional connecting webs 13 and 14 to the pressure webs 12 (see Figures 4 and 6), which extend perpendicular to the pressure webs 12 and again perpendicular to each other are arranged.
  • these connecting webs 13 and 14 in particular the bending stiffness and compressive strength in the different directions can be controlled in a suitable manner.
  • FIGS. 7 to 9 again show a pressure element 21 which differs from the pressure element 11 only in that a further connecting web 25 is provided parallel to the connecting web 23 (which corresponds to the connecting web 13 from FIG. 4).
  • FIGS. 10 to 12 an embodiment of a pressure element 31 is shown in FIGS. 10 to 12.
  • this pressure element has such pressure webs 32 which end at an arc and end into the adjacent plate-shaped pressure bearings 33, 34 (see FIG. 10) or into the connecting webs 35 and 36 (see Figure 11).
  • each pressure web 32 is provided with a recess 37 in order to reduce the heat transfer through the pressure element.
  • the spaces between the individual pressure bars can be used in all four of the embodiments shown Insulation material should be provided.
  • the advantage of the present invention lies in the fact that, due to their lamella construction, the pressure elements can be arranged in the lowest possible position within the joint and can even be designed with only a small height, thereby increasing the moment to be absorbed by the pressure element.
