Definitions

  • the present invention relates to a thermal insulation component according to the preamble of patent claim 1.
  • the reinforcement elements were continuously optimized, especially with regard to their thermal insulation properties, whereby in recent years there has been an increasing trend to producing the compressive force reinforcement elements from non-metallic building materials and in particular from high-strength concrete or mortar materials and applying them essentially to the area of the joint between the two adjacent components.
  • An exemplary component for thermal insulation was used, for example, in EP-A 1 225 282 or EP-A 1 225 283 described, wherein the compressive force reinforcement element is made of high-strength fiber-reinforced concrete and is tapered in horizontal section, so that it has a comparatively large front side for compressive force introduction and a compressive force-transmitting central area that is as slim as possible to optimize the thermal insulation properties. Since the front side of the compressive force reinforcement element has a convex contact profile facing the component in horizontal section with a curvature in the shape of a circular arc, this allows an articulated movement of the compressive force reinforcement element relative to the adjacent component along the arcuate curved surface.
  • the compression shear reinforcement element is approximately disk-shaped overall, with the disk being oriented in a vertical plane.
  • the disadvantage of such large-volume compression shear reinforcement elements is the large cross section, which causes a significant deterioration in the thermal insulation properties. Because an enlarged material cross-section in the vertical plane along the joint between the two adjacent components inevitably leads to a larger surface for heat or cold transport.
  • the material of the compression shear reinforcement element can be highly insulating, but the optimized material cannot compensate for the disadvantages of the large material cross section.
  • the object of the present invention is to improve a component for thermal insulation of the type mentioned at the outset with an improved force transmission corresponding to the compressive force reinforcement elements with regard to the thermal insulation properties.
  • support elements are assigned to the pressure elements, which are arranged at a different height level than the pressure elements and below the tensile force elements and below the tension zone in relation to the structural element when installed, with one pressure element and one support element each being operatively connected to one another via a transverse force element.
  • This modular structure is based on the knowledge that you can get the same advantages of a better one Force transmission can be achieved not only with a large-volume reinforcement element, but also with a design in skeleton construction.
  • the well-known large-volume compression shear reinforcement element is thus broken down into individual tension and compression struts along the force curves corresponding to a truss model.
  • the pressure element extends in a conventional manner as deep as possible in the insulating body in a horizontal plane between the two adjacent components.
  • the pressure element is combined with a support element and both are connected to one another via a transverse force element which runs inclined to the horizontal from one end of the pressure element to the diagonally opposite other end of the support element.
  • the pressure element, transverse force element and support element thus simulate a framework and essentially absorb the same forces that the prior art pressure shear reinforcement element is also intended to transmit.
  • the combination of pressure elements with shear force elements is already known, but the known shear force elements between the two components adjacent to the component joint extend from the lower pressure zone of one component into the diagonally opposite upper tension zone of the other component and are used for force transmission in the components directly or - as in the case of the DE-A-37 00 295 - Anchored indirectly by fixing to the lower pressure elements and the upper tension reinforcement elements. The support elements are therefore in the tension zone.
  • the transverse force element is operatively connected to the support element and this support element has the primary purpose of holding the transverse force element, so that it is subjected to tensile loads and the transverse force is downwards can pass on to the pressure element, the support element being arranged below the tension zone.
  • the support elements each protrude in relation to the insulating body and form transverse force projections in these protruding areas for support in the adjacent components.
  • the pressure elements also project in each case relative to the insulating body and form transverse force projections in these projecting areas for support in the adjacent components. This is because they can provide the shear force elements with the necessary abutment. It goes without saying that the direction of force, against which the support elements on the one hand and the pressure elements on the other hand have to fulfill their supporting function, are essentially opposite to one another, since they ensure that the connected transverse force elements are held and absorb and transmit the required loads can. For both types of transverse force projections, it is sufficient that the area in which they project into the components is essentially only large enough to ensure the desired support function.
  • the use of the support elements according to the invention has another advantage: they can be provided to support the pressure elements to prevent failure, so that if the support for the pressure element or for the pressure elements is omitted, the support elements can assume the task of supporting the component being carried. Although in this case the entire construction is no longer undamaged and can therefore no longer be used unchanged, this can prevent the supported component from folding down or even falling, and thus from the occurrence of major damage. So even if the supported component after the failure due to its weight and the lack of support of the pressure element slightly in its Position may be changed, then if the support element can take over the support, further folding or even falling of the supported component is prevented.
  • the support elements In order for the support elements to take over their function and to be able to carry the shear force element assigned to them, the support elements are arranged above the pressure elements in relation to the structural element in the installed state in accordance with the distribution of forces in the truss model.
  • This arrangement also has the effect that after the failure of an adjacent concrete component in the lower area adjacent to the component, if the lower edge area of the concrete component breaks away and the support for the pressure element is missing, the support element arranged above it can take over the support immediately, so that the supported component is hardly pivoted from its installation position.
  • the construction element according to the invention has additional reinforcement elements in the form of elements that transmit tensile forces, it being essential that the support elements are arranged below these tension elements and below the tension zone in relation to the construction element in the installed state, so that they actually perform their function as the support elements or support elements that carry the transverse force elements .can fulfill as additional pressure elements.
  • the structural element does not have any reinforcement elements that transmit tensile forces; Even then, the support elements should be arranged below the tension zone or in the pressure zone.
  • a support element that supports this element and/or a replacement pressure element for each pressure element is provided for each transverse force element, which can at least partially take over its task in the event of failure.
  • the support elements run through the insulating body essentially horizontally and transversely to the essentially horizontal longitudinal extent of the insulating body when it is installed and can be connected at least indirectly to both components and/or when the supporting elements are opposite to the pressure elements are arranged spaced apart and/or if the support elements extend essentially parallel and/or equidistant to the pressure elements.
  • the support elements take over and fulfill the task as the support elements carrying the transverse force elements and/or as a replacement pressure element.
  • each pressure element and support element via a transverse force element it is recommended above all that the transverse force element is fixed to the pressure element and support element in particular by mutual form-fitting connection. This not only makes it easier to install the pressure element and support element together, but the shear force element also allows forces to be transmitted, in particular in the direction of extension of the shear force element, which would otherwise have to be assumed by other reinforcement elements to be arranged in this area.
  • the transverse force element is arranged inclined to the horizontal relative to the component in the installed state and extends between one end of the pressure element and the diagonally opposite end of the support element; because such a pressure/shear force module allows shear forces or shear forces to be absorbed and transmitted, which would otherwise be assumed by the shear force bars usually used in such components for thermal insulation, the positioning and orientation of which the shear force elements are based on.
  • the transverse force element or the transverse force elements consist at least partially of fiber-reinforced plastic material.
  • This is not only inexpensive to produce and has very good thermal insulation properties, but its corrosion-resistant, non-metallic material properties also ensure that the desired deepest possible arrangement of the pressure elements in the construction element can be retained unchanged, which of course would not be the case if the shear force elements were removed would consist of a metallic material and below the shear force elements a minimum concrete cover would have to be observed.
  • the transverse force element is designed in the form of a loop with two loop strands that extend essentially parallel to one another, preferably next to one another or over one another.
  • transverse force elements can be used that can be optimally adapted to the installation situation in terms of geometry and load capacity.
  • the main advantage of fiber-reinforced plastic material is that, on the one hand, it can be sufficiently loaded in the direction of tensile force and, on the other hand, it has poor thermal conductivity, which is desirable in the area of the insulating body.
  • fiber reinforcements in particular glass fiber reinforcements, whose fiber content, in particular glass fiber content, is higher than 85% by weight, so that the weight of the matrix material used in addition to the fibers, such as synthetic resin, is less than 15% compared to the weight of this reinforcement element.
  • a second transverse force element related to the built-in component state for absorbing transverse forces is arranged inclined to the horizontal and the second transverse force element extends between the other end of the pressure element and the diagonally opposite end of the support element and the inclination of the second transverse force element differs from that of the transverse force element, in particular that both inclinations are essentially symmetrical are oriented opposite to each other from the vertical.
  • the two transverse force elements each have two loop strands at different distances from one another.
  • the loop of one transverse force element can run within the loop of the other transverse force element in the crossing area.
  • the pressure element and/or support element it is advisable to produce these from a pressure-resistant, hardening and/or setting material, in particular from a cementitious, fiber-reinforced building material such as concrete, such as high-strength or ultra-high-strength concrete or such as high-strength or ultra-high-strength mortar or from a synthetic resin mixture or from a reaction resin.
  • a cementitious, fiber-reinforced building material such as concrete, such as high-strength or ultra-high-strength concrete or such as high-strength or ultra-high-strength mortar or from a synthetic resin mixture or from a reaction resin.
  • the shape of the pressure element and support element can be optimized, particularly when they are made from a castable material. It is also advisable if the pressure element has a depression on its side facing away from the support element for receiving a first anchoring section of the transverse force element in a form-fitting manner and if the support element has a depression for receiving a second anchoring section of the transverse force element in a form-fitting manner on its side facing away from the pressure element. Merely this insertion of pressure element and transverse force element or transverse force element and support element can ensure the correct positioning and functioning of these elements without the need for costly or complicated precautions.
  • the first anchoring section of the loop-shaped transverse force element consists of a first apex area between the two loop strands that extend essentially parallel to one another
  • the second anchoring section of the loop-shaped transverse force element consists of a second apex area between the two loop strands that extend essentially parallel to one another.
  • the depressions in the area of the pressure element and the support element can advantageously form a winding form for producing the loop-shaped transverse force element, as a result of which the fibers of the loop-shaped transverse force element act on the winding form, i.e. the pressure element and/or the support element, at least partially and in particular over a large area in the apex area of the loop form and ensure a perfect mutual contact and thus an ideal power transmission.
  • the transverse force elements are installed together with the pressure and/or support elements actually used in their production as a winding form; However, similar effects can also be achieved if not the identical pressure and/or support elements, but only structurally identical in the winding form area, are used when installed together.
  • both the pressure element and the support element prefferably have a convex contact profile that can be rolled off on the components in the area of their terminal transverse force projection, so that the pressure element and/or the support element can produce an articulated connection between the two components.
  • the curvature of the contact profile in the installed state should be designed approximately in the shape of an arc of a circle in horizontal section.
  • the front contact profile of the pressure element and/or the support element is curved in vertical longitudinal section or inclined to the vertical, in particular if the front contact profile of the pressure element and the front contact profile of the support element have opposite inclinations to one another, so that the pressure element and the support element do not impede relative movements oriented in the vertical direction in relation to the adjacent components, but ideally can follow the movement similar to a parallelogram linkage or a pivoting element.
  • pressure elements and/or support elements it is also advantageous if they each have a smooth-walled and level upper and lower side, which upper and lower sides each extend in horizontal planes.
  • figure 1 shows a component for thermal insulation 1 with a cuboid insulating body 2, to be arranged in a component joint left between two concrete components, namely a supported component A to form a concrete and a supporting component B, which consists of part of a building, and these two Space concrete components A, B from each other in a thermally insulated manner, and with reinforcement elements in the form of tension rods 3 and in the form of pressure elements 5.
  • the reinforcement elements are arranged in the manner known and customary in the prior art, namely by in the upper area of the Insulating body 2, in the so-called tensile zone, the tensile reinforcement elements 3 are arranged, which extend in the installed state in the horizontal direction and serve to transmit tensile forces between the two components A, B connected to the component for thermal insulation 1 and are anchored in these components for this purpose.
  • the pressure elements 5 are arranged, also with a horizontal direction of extension, but they only protrude to a small extent relative to the insulating body 2.
  • the support elements 6, which also extend in a horizontal plane parallel to and at a distance from the pressure elements and are supported in a form-fitting manner in the adjacent component by protruding into the adjacent component relative to the insulating body and having terminal transverse force projections there, which in Related to figure 2 be described in more detail.
  • transverse force elements 4 are also provided, which run inclined to the horizontal in the area of the insulating body 2 . Here they extend from the supporting component B facing end 6b of the support elements 6 on the one side of the insulating body 2 diagonally downwards to the end 5a of the pressure elements 5 facing the supported component A on the other side of the insulating body 2.
  • a lower edge region of component B facing the insulating body arranged in the component joint is in figure 1 marked with the reference number 9. It is intended to indicate a failure area in which an aspect of the present invention is particularly recognizable:
  • the pressure element 5 is supported on this area 9 of the component B with its end area 5b facing the component. If this area 9 now breaks off as a result of an excessive load, the pressure element 5 lacks a support, so that it cannot absorb the load caused by the weight of the projecting component A. As a result, the projecting component A would buckle downwards, as a result of which the tension rods 3 would be subjected to bending stress and the entire structure would be damaged so badly that it could even cause the projecting component A to fall.
  • the support element 6 is arranged above the pressure element 5 according to the invention, it is supported on the component B above the failure area 9 and can therefore, as a replacement pressure element, protect the entire structure from excessive damage or the protruding component A falling. Although the construction can no longer be safely used after damage in the failure area 9, by supporting the support element 6 on the component B above the failure area 9, more serious consequences for objects and people in the area of the protruding component A can be prevented.
  • the transverse force element 4 is loop-shaped and that the pressure element 5 and the support element 6 embraces and embraces. If the pressure element and support element are used in the production of the loop-shaped transverse force element as a winding roll for the wet, impregnated plastic fibers before they harden, the plastic fibers not only form a positive connection with the pressure element and support element by gripping, but also a resilient connection due to the mutual contact during hardening adhesion connection.
  • transverse force projections 5g, 5h, 6g, 6h which respectively form the horizontal ends of the support element 6 and the pressure element 5, with the support and pressure element projecting into the adjacent components A and B opposite the insulating body.
  • they form a positive connection with the material of the components and thus ensure that the support element and the pressure element can be supported on the components in such a way that they serve as an anchor or abutment for the transverse force element 4 extending between the support and pressure element can.
  • a load acts on the transverse force element, it is subjected to a tensile load, and this load is passed on to the support element and the pressure element through the anchoring on the support element and the pressure element. Only because the support element and pressure element are anchored in the adjacent components via the transverse force projections can they absorb and counteract this tensile load.

  • the two transverse force elements 14a, 14b are each loop-shaped, with the transverse force element 14a consisting of two terminal deflection or apex areas 14aa, 14ab and two parallel loop strands 14a1, 14a2 connecting the two apex areas.

  • this is made up of two terminal deflection or apex regions 14ba, 14bb and two parallel loop strands 14b1, 14b2 connecting the two apex regions, which together form a closed loop shape.
  • the two loop strands 14a1 and 14a2 of the transverse force element 14a have a smaller mutual spacing than the two loop strands 14b1 and 14b2 of the transverse force element 14b.
  • Both the pressure element 15 and the support element 16 have transverse force projections 15g, 15h, 16g, 16h at their horizontal ends, with which they project into the components A, B in relation to the insulating body. So that the pressure elements and the support elements can establish an articulated connection between the two components A, B in the known manner by being supported on them in the manner of a pendulum joint during relative movements of the two components and being able to follow the relative movements, they have at the front ends of the transverse force projections on the Components A, B rollable convex contact profile.
