Definitions

  • the invention relates to a component for thermal insulation between a building and a cantilevered outer part, consisting of an insulating body to be laid between them with integrated metallic reinforcing bars which extend transversely to the insulating body and protrude on both sides, the insulating body having at least one bar firmly connected to it has, which consists of a harder material than the insulating body and has on its sides facing the components to be concreted recesses in which reinforcing bars are fixed.
  • each insulating body is equipped with a plurality of horizontally continuous tension and compression bars and possibly also with transverse force bars, the number of reinforcing bars depending on the length of the insulating body and on the forces to be transmitted between the subsequent concrete components.
  • tension rods relatively far from the insulating body, so that a sufficient coverage with the connecting reinforcement of the components to be concreted on both sides is ensured.
  • the tension rods are usually connected to a common cross rod in order to fix their position relative to one another and relative to the insulating body.
  • This position can be fixed by strips that are firmly connected to the insulating body and made of a harder material than this.
  • the insulating body consists of a material such as polystyrene or a similar foam-like plastic, the strips are made, for example, of a solid plastic, wood, fiber concrete or the like.
  • the strips thus contribute significantly to the stability of the entire insulating body, so that the risk is reduced that the insulating body will break during transport or during handling on the construction site.
  • the strips have the disadvantage that, due to their small thickness, they only hold the reinforcement bars over very short sections, so that it is possible that the reinforcement bars move undesirably axially in their position or even fall completely out of the bar.
  • This object is achieved in that in the direction of extension of the reinforcing bars are arranged laterally next to the recesses connected to the bar brackets that prevent a reinforcing bar from falling out of a recess.
  • the brackets have resilient elements at their edges, with which the opening of the bracket can be at least partially closed automatically.
  • the resilient elements recede when the reinforcing bars are pressed into the bar and, after passing through the reinforcing bar, spring back into a position that blocks a backward movement of the reinforcing bar.
  • the resilient elements extend essentially in the direction of the slots, a functionally reliable mode of operation is possible.
  • the holders In another holder, in which the recesses in the strip are open slits towards a strip edge, the holders have locking rails on the side of the reinforcing bars, which engage with closure bodies extending transversely to the recesses. Through the use of a locking body which snaps into locking rails, a secure fixation of the reinforcement rod is also achieved in the recesses.
  • closure body and / or the locking rails are advantageous to equip the closure body and / or the locking rails with a large number of catches arranged one behind the other, since the closure body can thus be used with reinforcing bars of different thicknesses.
  • the closure body and / or the recesses are V-shaped on their sides facing the reinforcement bars, in the case of reinforcement bars of different thicknesses, a central mounting of the reinforcement bar can be achieved in the recess, which affects the dimensional accuracy of the component with regard to the connecting reinforcements components to be concreted is advantageous.
  • the holders are molded onto the reinforcing bars as sleeves that can be connected to the bar. A particularly robust holder is thus achieved.
  • the sleeves can be molded as a molded part directly around the reinforcing bars, which results in a very intimate connection between the sleeve and the reinforcing bar, which is advantageous for fixing the reinforcing bar.
  • the intimate connection of the reinforcing bar and the sleeve prevents an axial displacement of the reinforcing bar with respect to the sleeve and thus the bar.
  • the cuff In order to then connect the cuff to the bar, it can have a spike-like extension which interacts with an opening in the bar.
  • a spike-like extension which interacts with an opening in the bar.
  • it is proposed to rivet the mandrel-like extension after it has been inserted through the opening. This is particularly useful for thermoplastic materials.
  • FIG. 1 the lower part of a component for thermal insulation between a building and a cantilevered outer part is shown. It consists essentially of an insulating body 1 in which metallic reinforcing bars 2 are integrated. The reinforcing bars 2 extend transversely to the insulating body 1 through it and protrude on both sides, where they are connected to the connecting reinforcement, not shown, of the components to be concreted.
  • the insulating body 1 is closed at its end by a U-rail 3, the legs of which are formed by strips 4.
  • the U-rail consists of a harder material than the insulating body 1, which is usually made of polystyrene or the like.
  • the strips 4, which form the legs of the U-rail 3, have recesses 5 in which the reinforcing bar 2 is fixed.
  • the strips 4 are very narrow and therefore only carry the reinforcement bar 2 over a very short distance.
  • brackets 6 extend laterally next to the recesses and additionally fix the reinforcing bar 2 with respect to the U-rail 3 and its strips 4.
  • the recesses 5 are open towards the ledge edge 7, the holders 6 having resilient elements at the edges of their opening.
  • These resilient elements are formed by leaf spring-like spring elements 8.
  • the metal reinforcement bars can be inserted into these U-rails during manufacture of the insulating body, and the U-rails equipped in this way can then e.g. be put on the insulator from above without the risk of the reinforcing bars falling out.
  • FIG. 3 Another possibility for fixing reinforcing bars in the U-rail or in the bars forming their legs than in FIG. 1 is shown in FIG. 3, in which the same parts are provided with the same reference numbers.
  • the brackets adjoining the strips 4 laterally have latching rails 9.
  • FIG. 6 in which the strips of FIG. 3 are shown in side view, it can be seen that these locking rails are provided with a plurality of detents 10 arranged one behind the other. These catches act together with catch teeth 11 on a closure body 12 shown in FIGS. 4 and 5.
  • the reinforcement bar 2 inserted into the V-shaped recess here is as deep as possible in these recesses.
  • the closure body 12 which extends transversely to this recess, is pushed onto the strips 4.
  • the edges of the recesses of the strip 4 slide in grooves 13 which are formed on the closure body.
  • the closure body 12 presses the reinforcing bar into the V-shaped recess, the locking teeth 11 interlocking with the detents 10 of the locking rails 9 and preventing the closure body from sliding back.
  • the reinforcement bars Due to the contact forces that can thus be exerted on the reinforcement bars via the closure body, the reinforcement bars are prevented from sliding out when the U-rail is manipulated as described above with inserted reinforcement bars.
  • FIGS. 7 and 8 Another variant for securely fixing a reinforcing bar is shown in FIGS. 7 and 8, in which the same parts again have the same reference numerals are provided.
  • 2 sleeves 15 are integrally formed on the reinforcement bar, which can be connected to the strips 4.
  • the sleeves surround the reinforcement bar 2 over its entire circumference, as shown in FIG. 8.
  • they can be molded directly onto these reinforcing bars as plastic parts.
  • the cuff 15 has a spike-like extension 16 which projects through an opening 17 on the U-rail 3. Since the sleeve is molded from thermoplastic material, the portion of the spike-like extension protruding from the opening 17 can be deformed into a mushroom-shaped head 18 as shown on the left, so that the sleeve is firmly connected to the U-rail 3 and thus to the strips 4. So that the mushroom-shaped head 18 does not protrude on the outside of the U-rail, it has a recess 19 in the area of the opening 17, in which the mushroom-shaped head 18 comes to lie without applying to the outer contour of the rail.
