  • this has two through holes 128, through which a wire can be passed, in order to connect a reinforcement, not shown in the figure, to the insulation holder 100.
  • FIG. 2 to FIG. 5 show further, provided with purely exemplary dimensional information cross-sectional views of the insulation holder 100 according to the described exemplary embodiment.
  • FIG. 6 and FIG. 7 show other spatial views of the insulating body 100.
  • FIG. 1 to FIG. 7 different embodiments of embodiments of the invention possible.
  • an insulation holder 800 according to another exemplary embodiment is shown in FIG FIG. 8 shown free of holes 128 in the cover plate 126 for securing a reinforcement.
  • the cover plate 126 is according to Fig. 8 formed as a continuous circular disk.
  • FIG. 9 shows that after casting with liquid concrete, an insulation holder 900 according to another exemplary embodiment enables a secure connection between an insulation panel 902 and a concrete wall 904 formed by the casting.
  • the anchoring of the insulation holder 900 is accomplished in the insulating plate 902, that a part of the surface of the insulation holder 900 is coated with an adhesive before it is introduced into the insulation plate 902.
  • the friction between insulation holder 900 and insulation plate 902 may be sufficient to cause sufficient anchoring force.
  • FIG. 9 shows that a Dämmscherlement remedyen end portion 190 of the insulating material holder 900 is disposed in the interior of the insulating plate 902 and the according to FIG. 9 left main surface of the insulating plate 902 not pierced.
  • FIG. 9 shows that the end stop surface 140 is in contact with a surface 906 of the insulation board 902.
  • FIG. 10 to FIG. 12 show different views obtained in a method of forming an assembly according to an exemplary embodiment of the invention.
  • FIG. 10 shows a state in which an inventive insulation holder is inserted with a tip 110 in an insulating plate 902.
  • a user applies a corresponding compressive force to insert the insulation holder 100 into the insulation board 902.
  • the user can use the lid member 126 as an actuator.
  • FIG. 11 shows a subsequent state in which the Verspreizanschlag composition 104 of the insulation holder with a surface 906th the insulating plate 902 comes into contact. A deeper insertion of the T-piece of cutting edge body 102 and Verspreizanschlag requirements 104 in the insulating plate 902 is no longer possible.
  • components 102, 104, on the one hand, and expansion limbs 116, 118, on the other hand can be parts of a one-piece device, which are coupled by means of a predetermined breaking element.
  • the predetermined breaking element can be configured in such a way that it is destroyed only when the Verspreizantschization 104 is struck against the insulating plate 902, since then the entire pressure force of the user between components 102, 104 on the one hand and expansion limbs 116, 118 acts on the other.
  • the guide rails 116, 118 slide on the conically widened undercut portion 112 of the cutting edge body 102, thereby causing a lateral spreading of the expansion leg 116, 118 in the insulating plate 902, resulting in a transverse force and thus to secure anchoring of the insulation holder 100 in the insulating plate 902 leads.
  • the insulation holder 100 After casting with liquid concrete (not shown), the insulation holder 100 allows a secure connection between the insulation plate 902 and the concrete wall 904.
  • FIG. 13 and FIG. 14 an insulation holder 1300 according to another exemplary embodiment of the invention described.
  • FIG. 13 shows a cross-sectional view and FIG. 14 shows a side view of the insulation holder 1300th
  • the insulation holder 1300 corresponds in many ways to the insulation holder 100 according to Fig. 1 , differs from this, however, especially with regard to the special features presented below.
  • the building element-side end portion 180 has at the Dämmstoffhalter 1300 two opposing clamping jaws or clamping wings 1304, 1306, the Dämmscherlement question are interconnected by means of a flat connecting plate 1302 and are spaced building element side apart.
  • the flexible and elastic clamping wings 1304, 1306 have free ends 1320, 1322 which are movable toward or away from each other when a force is exerted.
  • the mutually mirror-symmetrical and arranged clamping wings 1304, 1306 have facing U-shaped leaf spring-like indentations 1308, 1310 on.
  • the clamping wings 1304, 1306 are laterally tapered in the region of their leaf-spring-like indentations 1308, 1310, as in FIG Fig. 14 shown to increase the elasticity locally and thus to improve the clamping ability.
  • the tensioning wings 1304, 1306 also have bulges 1312, 1314 which, together with the limiting plate 1302 connecting the bulges 1312, 1314, define a maximum penetration depth of the insulating material holder 1300 into an insulating element.
  • Fig. 13 shows, each of the outwardly projecting free ends 1320, 1322 first in one of the recesses 1308, 1310 and the latter in the each associated with the bulges 1312, 1314 via, which are then connected to each other via the connecting plate 1302.
  • the cutting edge body has a W-shaped front portion having two tips 110 with a V-shaped notch 1330 therebetween.
  • the clamping wings 1304, 1306 can bend and then set up again.
  • the tensioning wings 1304, 1306 are thus - in contrast to conventional holders - not destroyed.
  • the clamping wings 1304, 1306 can thus be bent, then elastically erect or spring back and then still perform their function, i.
  • the introduction of the anchor or insulation holder 1300 in the insulation or insulation board by the clamping wings 1304, 1306 can be facilitated. It is possible to temporarily clamp a hammer head with the clamping wings 1304, 1306, so that the entire anchor or insulating holder 1300 is held on the hammer.
  • the anchor or Dämmstoffhalter 1300 can now be beaten easily with the aid of the hammer in the insulation or in the insulating element, whereby a holding of the anchor is avoided with one hand and a hammer with the other hand.
  • FIG. 15 to FIG. 18 Illustrate such an embodiment FIG. 15 to FIG. 18 , which are described in more detail below. These show spatial views while performing a method according to an exemplary embodiment of the invention for inserting the insulation holder 1300 into an insulation plate 902 using a hammer 1502.
  • FIG. 15 shows how a hammer head 1502 is clamped between the clamping wings 1304, 1306 of the insulating material holder 1300.
  • FIG. 16 shows how by means of the hammer head 1502 of the insulation holder 1300 is inserted into the insulation plate 902 so far that the stop plate 114 is seated on the insulation plate 902.
  • FIG. 17 shows, as by means of the hammer head 1502, the insertion of the insulation holder 1300 in the insulation plate 902 starting from the state according to FIG. 16 will continue. In this case, the insulation holder 1300 is further inserted into the insulation plate 902 until the connection plate 1302 is seated on the stop plate 114 and thus almost on the insulation plate 902.
