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 insulator to be laid therebetween with at least integrated pressure elements in the installed state of the component substantially horizontally and transversely to the substantially horizontal longitudinal extent of the insulating body run through it and can be connected in each case to both components.
  • Such components for thermal insulation are known in the relevant state of the art in many different versions and serve to decouple two components from each other thermally, but at the same time statically connect them together. This static connection takes place via reinforcing elements, which extend through the insulating body between the two components and the respective occurring loads, so in particular tensile, compressive and shear forces transmitted safely.
  • An essential field of application of such components is, for example, in balconies that protrude from a building exterior wall and are suspended on said reinforcing elements on the same height ceiling with the interposition of a component for thermal insulation. Since these balconies are exposed to different temperatures than the floor slab running in each case in the insulated building interior, temperature-related relative movements occur between the two components, ie between the balcony and the floor slab. Because while the floor ceiling at substantially the same temperature Depending on weather conditions and the season, the outside temperature and thus the temperature of the balcony slab varies by more than 10 ° C per day.
  • the present invention is therefore based on the object to propose a component for thermal insulation, which allows elastically or reversibly resilient pressure elements for receiving relative movements between the adjacent concrete components, on the one hand, the flexibility independent on the material of the printing elements and on the other hand should be available as much as possible without the unwanted noise developments described.
  • the pressure elements each have a contact profile that can be rolled on the concrete components and if the pressure elements can produce a joint connection between the two components.
  • This hinge connection is obtained independently of the pressure element material, ie even with high-strength rigid materials.
  • the resulting pendulum joint-like pivoting movement leads to a significant reduction of the actual displacement.
  • the relative movement of two concrete components in the order of 2 mm results in a rotational movement of the pressure element relative to the adjacent concrete component in the mutual contact area with a relative movement of only 0.2 mm. From this example, it is easy to see that this significantly reduced displacement is accompanied by a correspondingly significantly reduced to a negligible amount of noise. In the same sense, the fact that part of the previous sliding or friction movement is replaced by a rolling movement.
  • the contact profiles in the installed state should be anchored in the concrete components such that the pressure elements only with the curved Projecting contact area in the concrete components to allow the unimpeded rotational movement between the pressure element and concrete component.
  • the circular arc-shaped cross section of the contact profiles extends over the entire height thereof.
  • each contact profile is designed in the form of a cylinder jacket part surface.
  • the horizontal cross sections can also change over the height of the printing element, such. B. at a sheath part surface of a truncated cone. This ensures that the power transmission between the pressure element and the concrete component takes place over the entire contact profile surface.
  • a preferred design of the contact profiles is that they also have a concave outer surface which is also curved in the vertical direction, that is, they are also arched in a vertical longitudinal section. This allows them to follow any vertical settlement movements between the two components without affecting their function.
  • the pressure elements thus formed give way slightly articulated and are - despite a slightly inclined position compared to the horizontal installation - yet full surface with their frontal contact profiles on the adjacent concrete components.
  • the printing element continuously and without offset pass into the contact profiles to keep the surface of the contact profile as small as possible and - at least approximately - only so form large, as the dimensions, ie in particular the cross section, the pressure-transmitting transmitting behind the contact profiles arranged pressure elements.
  • an elastically or reversibly compliant bearing can be achieved by the pressure elements according to the invention independently of their material, so that the advantages of the present invention in particular come in printing elements made of hard unyielding or high-strength material to fruition.
  • high-strength concrete can also be used.
  • the pressure element must not even in the transverse direction elastically temperature-related longitudinal movements between the two adjacent components can follow, but by the rolling motion, it can also be made of high-strength material - such as concrete.
  • a particularly suitable form of use of concrete printing elements results from the fact that they are made by casting, which has a great many possibilities in terms of shape and surface design of the printing elements.
  • cross-sectional reductions in the central region between the two end-side contact profiles can be produced, which are decisive for the degree of thermal conductivity or for the heat transfer through the pressure element.
  • Such cross-sectional reductions can take place both in the horizontal direction and in the vertical direction, so that the pressure element is formed in a waisted horizontal section with a tapering in the direction of the central region between the two end contact profiles and on the other hand, the height of the pressure element in the direction the middle area between the two frontal contact profiles reduced.
  • the printing elements are produced from a lost casting mold, this can advantageously be exploited to form two continuous printing elements which form a double printing element, leaving a space between the two printing elements in which, for example, a transverse force rod can be used can be fixed to the mold. Moreover, it is also possible to fill the gap by insulating material or form as enclosed by the mold and filled with air cavity.
  • a component 1 for thermal insulation is shown in fragmentary section through the indicated in Figure 2 level 1 - 1.
  • the component 1 is installed in a between a concrete building A and a cantilevered concrete outer part B left gap and consists essentially of an insulating body 2 filling the joint and reinforcing elements in the form of printing elements 3 shown in FIGS. 1 and 2.
  • Figure 2 does not show the component 1 with all its individual parts and in its entire height; rather, the upper insulating body portion carrying the commonly used tie rods, which has nothing to do with the present invention, is not shown. Also missing is the representation of a transverse force rod, extending from the supporting component, the building A, in the direction of the supported component, the balcony B, obliquely from top to bottom through the insulator or the gap filled by the insulating body extends and protrudes into both components to the transverse force introduction.
  • the pressure element 3 runs essentially horizontally through the insulating body from the component B to the component A. At the end faces 5, 6 facing the components, the pressure element 3 has arched contact profiles which act as a pressure force input and output surface and according to FIG illustrated horizontal section are formed circular arc. Over the entire surface of the contact profiles, the overall shape of a cylinder jacket part surface results due to this circular arc shape, since the pressure element in each case has a constant cross section over the height.
  • the effect of the circular arc shape is as follows: If the two components A and B relative movements from each other, so form the arcuately curved contact profiles hinge surfaces that allow the relative movement without it comes in the contact area between contact profile and adjoining concrete component to large displacement movements. As a result, the actual relative movements between the concrete components and the pressure elements can be significantly reduced and as a result one obtains pressure elements that can follow reversible and without significant noise independently of the material temperature-induced displacement movements.
  • FIG. 3 An alternative design of the present invention is shown in Figure 3: There is a device 11 for thermal insulation between a building A and a balcony B, shown in horizontal section at the height of printing elements 13a, 13b. Between building A and balcony B also an insulating body 12 is shown, which extends along the gap left between the two components.
  • each one pressure element is replaced by two parallel pressure elements that require a correspondingly smaller force introduction surface in the form of contact profiles 15a, 15b, 16a, 16b. This results in a double joint similar to a parallelogram, which further reduces the displacement between the contact profiles and the adjacent concrete components.
  • Both types of pressure element have, in addition to the circular arc-shaped contact profiles also very similar pressure element cross-sectional shapes, namely a continuously and without offset from the edges of the contact profiles passing gob-like outer shape, which tapers slowly to the center of the joint and then on the way to the opposite contact profile again continuously disseminated to there absatzlos in to transition the edges of the opposite contact profile.
  • This shape ensures optimum introduction of force from the balcony slab B into the pressure element, optimum pressure force transmission with reduced heat conduction through the joint and optimal pressure force discharge into the building A.
  • the cross sections are designed so that they are at the largest possible force introduction surface and slender Druckkraftübertragungsquerroughs Design at mutual continuous transition yet kink-resistant, stable pressure element with - due to the small cross-sectional area - still more favorable thermal insulation, especially if used as a material for the pressure element concrete.
  • a lost casting mold 20 is shown in perspective view in FIGS. 4 to 6, which is used to produce concrete pressure elements and is used together with the concrete pressure elements in the thermal insulation component according to the invention (not shown here).
  • Figures 7 to 13 show only the mold 20 and not the concrete pressure elements themselves; these correspond in their appearance and their arrangement approximately the design of Figure 3, wherein the lost mold is, however, intended to be installed together with the concrete pressure elements in the device for thermal insulation, so far so the representation of Figure 3 is not directly related to the embodiment transferable from Figures 4 to 12.
  • the casting mold 20 has two cavities 21, 22 which are to be filled with concrete and which are open in the installed position, which predetermine the shape of the concrete pressure element.
  • the concrete pressure elements obtained by the mold has a structure that relates both to The horizontal section as well as with respect to the vertical section to the center tapers: Using the example of the cavity 21 enclosed by the mold 20, this means that the concrete pressure element in the direction of the largest possible cross-sectional and surface in the region of the end-side curved contact profiles 23, 24 the central region 25 between the two contact profiles is tapered; With reference to a horizontal section which can be seen from FIG.
  • the transitions from the large surface of the contact profiles 23, 24 to the reduced cross sections in the central region 25 are fluid.
  • the casting mold 20 has a connection region 26 between the two cup-shaped individual casting molds 20a, 20b surrounding the cavities 21, 22. In this connection region, a cavity 27 enclosed by the casting mold 20 is left, which is filled with air and serves as an insulating body. In the adjacent to the connecting portion 26 between the two Einzelg screenformen 20a, 20b arranged area a recess 28 for receiving a transverse force bar is provided, which dips into the space between the two pressure elements and is fixed there to the mold.
  • the mold has on its outer side vertically extending webs 29, 30, which are provided to seal the lateral gap between the two molds by laterally joining an adjacent double pressure element with a correspondingly constructed mold by each of the individual webs 30 in the space between the dip both double bridges 29. This prevents liquid concrete from flowing into the gap between the two casting molds and impairing their function.
  • the mold 20 also has at the edge of an end-face contact profile 23 in a horizontal section T-shaped web, which is intended to project into the adjacent concrete component - in particular in an integrally formed in a precast Filigranplatte and be anchored to this form-fitting manner.
  • the rolling contact profile has the disadvantage of not providing a connection in the pulling direction, which is particularly relevant during transport; Therefore, the T-shaped web 31 serves as a drawstring for the transmission of tensile forces between mold or associated printing elements and adjacent concrete component.
  • the mold has on its upper side hole-like recesses 32; these serve to promote the escape of air during the casting of the printing elements; In addition, they ensure a positive connection between the mold and concrete pressure element due to emerging from the openings 32 concrete material and thus serve as a transport and captive and prevent falling out of the pressure elements from the mold when the mold is oriented so that the cavities 21, 22 after are open at the bottom and the printing elements could fall out.
  • the mold has on its underside hook-like latching lugs 33, which serve to lock the mold on a surrounding the device for thermal insulation on the underside of the rail and set.
  • the pressure elements in the region of the contact profiles 23, 24 with their lower foot region 23a, 24a project further into the associated component (A, B) than with their upper head region 23b, 24b.
  • the mold 20 functioning as a sliding layer for the contact profiles is provided with a greater thickness in the lower foot region 23a, 24a, since the stresses due to edge pressure are highest in this region.
  • the present invention offers the advantage of providing pressure elements that do not have to be elastically yielding even in the transverse direction, but that are elastically yielding transversely with respect to the adjacent concrete components.
