Definitions

  • the invention relates to a profile element according to the preamble of claim 1.
  • profile elements are widely known in practice in the form of plastic hollow chamber profiles.
  • metallic reinforcement profiles into the hollow chambers of the profile. Adequate bending stiffness can thereby be achieved.
  • the metallic reinforcement profiles represent a cold or thermal bridge, so that the thermal insulating effect of the profile element can be impaired and / or an increased additional effort is required to achieve or again the desired thermal insulating effect of the profile element manufacture.
  • the metallic reinforcement profiles represent a cold or thermal bridge, so that the thermal insulating effect of the profile element can be impaired and / or an increased additional effort is required to achieve or again the desired thermal insulating effect of the profile element manufacture.
  • the invention is based on the object of improving a generic profile element to the effect that it is free of cold bridges when achieving a high bending stiffness and enables the easiest possible workability.
  • the invention proposes, instead of using metallic reinforcement profiles, to use tensile fibers which are tensile in the longitudinal direction of the profile element. During the bending stress, part of the profile element is pressed and another part of the profile element
  • the arrangement of the fibers within the profile element must be selected.
  • two strands of fibers can be provided in the profile element, those on two opposite sides of the neutral
  • Chamfers of the profile element are provided so that a bending stiffness in relation to the bending stress is achieved in two directions. If necessary, however, only a single strand of tensile fibers can be provided, one being formed by the composite which the profile element forms with a number of other profile elements to form an entire door or window frame sufficient overall rigidity of this frame compared to the comparatively low individual rigidity of the individual profile element can be achieved.
  • the fibers can preferably be arranged in the profile element in the prestressed state.
  • two fiber strands of these tensile fibers must always be provided at two opposite locations of the profile element, so that after the introduction of these tensile fibers, the profile element is not deformed, but the prestresses of the two fiber strands are neutralized.
  • a particularly tensile connection between the fibers and the profile element can be achieved by extruding the fibers together with the plastic, or it can be achieved by gluing or welding the fibers to the plastic. If appropriate, provision can be made to arrange the fibers between two plates or between two struts of the hollow chamber profile and then to glue or weld these two plates to one another, so that the tensile fibers can be fixed securely and, if necessary, maintaining their pretension. Welding can be effected with the means known to the person skilled in the art, for example using filler materials or without additives, for example by ultrasonic welding or the like.
  • the fibers can be connected directly to a section of the hollow chamber profile. If necessary, however, the problem of poor accessibility can occur, in particular if the fibers are to be arranged in the profile element in a prestressed state. Therefore, a simpler introduction of the fibers can advantageously be provided on a separate component which is then used for
  • the separate component can be designed as a core, which is inserted into the rest of the cladding tube-like component instead of the metallic reinforcement, so as to create the overall profile element.
  • such a core can preferably consist of a lightweight structure, for example by three-dimensionally structured plates or by using foamed materials.
  • These lightweight structural elements can have a high mechanical stability, in particular a high flexural strength, in particular due to the additionally provided tensile fibers, and they can, due to cavities, the thermal insulating effect of the door or. Influence window frames positively.
  • the use of recycled material can be provided for the core, so that the waste and waste quantities that occur in a profile element manufacturing plant can be used without any problems be able to produce cores with the help of which the hollow chamber profile elements can be stiffened.
  • Unidirectionally oriented monofilaments are preferred as tensile fibers, so that the highest possible tensile strength is achieved with the least possible use of material and space requirements.
  • glass fibers or carbon fibers, and possibly also metallic fibers are suitable as the material.
  • not carbon fibers If the tensile fibers are provided in a core produced separately from the rest of the hollow chamber profile, a particularly close, precisely fitting connection can preferably be provided between this outer hollow chamber profile and the core in order to ensure the highest possible bending stability of the profile element.
  • the prestressed fibers are preferably fastened simultaneously on two sides of this component, which lie opposite one another with respect to the neutral fiber, in order to reliably preclude deformation of the component if the component is relieved after the fibers have been applied and the prestressed fibers are otherwise underneath
  • fibers can be applied to the component in different directions one after the other, so as to make the component more rigid in relation to different ones
  • rod-like components which are fiber-reinforced according to the present proposal, can also be provided for the manufacture of masts, beams or the like in addition to window and door profiles; According to the present proposal, fiber-reinforced panels can be used, for example, in vehicle or container construction and in the furniture industry.
  • FIG. 1 shows a cross section through the outer tubular component of a two-part hollow chamber profile element
  • Fig. 2 shows a cross section through the associated core as the second component of the two-part hollow chamber profile element
  • Fig. 3 shows a cross section through the profile element with built-in core.
  • FIG. 1 shows a hollow chamber profile 1 which has a closed, tubular cross section which includes two hollow chambers 2 and 3.
  • the hollow chamber profile 1 adjusts
  • the core 4 has four cover plates 5, between which a plurality of three-dimensionally deformed lightweight plates 6 are arranged, which have wavy or knob-shaped or pyramid-shaped projections and enable high pressure resistance with low weight.
  • the cover plates 5, which are in direct contact with the lightweight panels 6, merely represent the inner layers of two layers.
  • the two layers Narrow sides of the core 4 provided outer plates 7 and the two inner cover plates 5 each receive a layer of tensile fibers 8 between them, which have a high tensile strength in the longitudinal direction of the core 4.
  • These are unidirectional glass fibers which have been held under tension and connected to the cover and outer plates 5 and 7. Due to the pretensioning of the fibers 8, the core 4 has a very high bending stiffness.
  • FIG. 3 shows that the core 4 is accommodated in a precisely fitting manner in the larger hollow chamber 3 of the hollow chamber profile 1, so that overall a very rigid profile element 9 is created by the combination of the outer and inner profiles.
