Definitions

  • the present invention relates to a reinforcing element for plastic manufactured hollow chamber profiles, such as plastic window frames in particular.
  • the strength of such a construction is high. But it is essential Disadvantages connected.
  • the steel profile represents a cold bridge, the leads to relatively high heat losses of the frame, the K-value is approximately 1.6, of course, the steel content increases the weight, resulting in an increased Wear of the hardware parts, with which e.g. Frame and sash connected become.
  • the steel part has to be galvanized to protect it from rust, which is known to require an environmentally harmful process.
  • the Cut point after cutting to length for the same reason what however, is often omitted for convenience and thus to a degraded one Life of the frame leads.
  • stiffening plastic frame profiles is e.g. B. shown in EP 0 053 662.
  • a reinforcing element from a z. B. Thermoplastic foam inserted into the profile, this opposite Has top layers.
  • Such a bracing has an improved one K value, but at the same time takes less strength than a radiation set in purchase.
  • the present invention has therefore set itself the task of a reinforcing element to find that does not have the aforementioned disadvantages, which in particular ensures the same strength as a steel insert, but which significantly reduced K values, easy to manufacture and post-processing not required after cutting to length.
  • a reinforcing element for Frame profiles made of plastic, such as in particular Window profiles the reinforcing element being an open, essentially Has a U-shaped cross section and the reinforcing element according to the invention is made of a fiber composite material. It is divided into legs different thickness with a relatively thicker support leg and relatively thinner Spacer and guide legs, the fiber content in the composite material is selected so that the reinforcing element is produced using the pull-trusion process leaves.
  • a reinforcing element with the aforementioned features has the same high mechanical strength, such as steel, with the reinforced support leg to be inserted into the plastic profile in such a way that it is in place the highest (tensile) load and the other legs in terms of their Material consumption are adapted to the lower requirements there, so that the new reinforcement elements do not require a higher price.
  • the fiber content in the composite is chosen so that the elements as a strand Pulltrusion can be produced and therefore inexpensive for this reason can be produced, which in this respect is surprising, as composite materials are more expensive than profile steel.
  • the K value achieved is (for a 58 mm Frame) at 1.1, is about 30% cheaper, which is the case with the make up entire windows up to about 10% reduction in heat loss can and reduces heating costs accordingly.
  • the weight of the frame itself can also be reduced by approximately 10% in this way.
  • GFK fiberglass
  • PEEK thermoplastics
  • the proportion of fiber material set to about 60 to 90 wt .-% This can be in the Adjust thighs differently, with a fiber portion for all purposes in the support leg of about 70 to 90 wt .-% and in the other two legs such a 60 to 80 wt .-% has proven to be particularly suitable.
  • the reinforcement element is in the frame profile by gluing or screwing fixed, i.e. statically coupled with this. To the composite material over a It is also proposed to be able to securely connect the screw connection to the frame, at least on one side on the desired surface of the element to reinforce an outer fabric layer (inside and / or outside) to the Prevent tearing out of composite material.
  • the wall thickness of the reinforcing element can be on the spacer and guide legs down to 1.5 mm are selected, usually they are here up to about 3 mm, whereas the support leg is about 4 to 15 mm and is always stronger than the other two.
  • the installation in the hollow profile is done so that the support leg (or the four elements combined in the frame) where the higher tensile load occurs, in the case of the window sash, this is the one facing inwards towards the building Side and the center post (fighter) whose outer flank, the elements the frames to the desired extent with (compared to steel) less Brace weight.
  • the elements of the invention have a shape that the insertion in the possibly required different position in the hollow chamber Frame leg allows.
  • the support leg additionally stiffened by a steel insert.
  • This can consist of one Flat ribbon, but in particular also consist of an angle profile.
  • FIG. 1 shows an embodiment with two window sashes and a post 9 standing between them, each of which is designed as a frame made of plastic with hollow chambers 1.
  • the reinforcing elements 2 are inserted into the hollow chambers 1. This have a relatively thick support leg 3, one adjoining this Spacer leg 4 and a guide leg 5, both of which are made thinner are as the support leg 3 and each at an approximately right angle to each other connect.
  • a nose 10 which is close to the fitting groove extends.
  • the legs 4, 5 can be provided with an external resin-coated fabric layer 6 (Roving) to improve the fit of screw connections.
  • the Reinforcing elements 2 can also with the inner walls of the hollow chambers 1 are glued, this is facilitated by the fact that the frame profiles have bulges 13, 14 inside, which the legs 3, 4, 5 of the distance each wall so that an adhesive layer when inserting the Reinforcing elements is not stripped.
  • Figure 2 shows a reinforcing element in which the support leg 3 is reinforced by a steel insert 17 in the form of a flat strip.
  • FIG. 3 illustrates a form of the reinforcing element in which grooves 20, in particular for receiving adhesives, are formed in the guide leg 5 and the support leg 3. Furthermore, the spacer leg 4 and the guide leg 5 have reinforcing strips 21, which can also be covered with fabric (rovings) and serve for screwing to the frame. In addition, the grooves 20 and the strips 21 also act as beads and stiffen the profile.
