  • This task is accomplished by a generic holding device solved, which is characterized in that the anchor stone is manufactured on hydraulic high-pressure presses.
  • the manufacture of ceramic advantageously fulfills Anchor stones on high pressure hydraulic presses consistently homogeneous quality standards, so that they Comparison to standard, hand-made or plastic manufactured format present anchors clearly higher quality level of mechanical and mineralogical Have properties and also cheap in Manufacturing are.
  • the anchor stone tapers conically towards the furnace wall.
  • the anchor stone with at least a groove and / or groove is configured.
  • the invention proposes that one or more Grooves and / or one or more grooves offset from one another, are arranged all around.
  • the invention proposes that the fastener is metallic.
  • Fastening means includes a claw attached to the anchor stone attacks.
  • the fastening means has a bracket, on the one hand with the claw and on the other hand is connected to the furnace wall.
  • the invention proposes that the bracket to the Claw is screwed on.
  • the Furnace wall is metallic, and the bracket to the furnace wall is welded on.
  • a further development according to the invention is characterized in that that the fastener is a spring, preferably in the form of a spring plate.
  • the invention proposes that the spring the anchor stone physically contacted.
  • the anchor stone is experienced by means of the spring or the spring plate, in the claw, advantageously a flexible, "floating" storage, on the one hand a stable bracket the monolithic lining on the train and on the other free movement of the anchor stone in the fastener enables.
  • installation technology is absolutely essential required traction of the anchor stone by driving in wooden or plastic wedges causes, due to the wedge connections by both transient as well as stationary thermal influences that to possibly anisotropic expansion of the materials and uncontrolled
  • the anchor stones can cause tension tear and / or the fasteners are damaged can.
  • the spring is screwed to the bracket and / or the claw.
  • the invention proposes that a screw, preferably a hexagon screw including hexagon nut, for the connection between the claw, the bracket and the spring plate is screwed.
  • Hexagon nut which also as pure assembly aids no special requirements, for example with regard to their temperature behavior must meet, is manufacturing technology and inexpensive.
  • At least one elastic sealing ring preferably a rubber-like O-ring, arranged in the screw connection of the fastener is.
  • two elastic sealing rings can be used be provided, one between the head of a screw and one side of the fastener and another between the other side of the fastener and a nut.
  • the flexible use of the anchor stone by using the Feather is still elastic by the action of the or Sealing rings reinforced in the screw connection. It is particularly advantageous that not only the anchor stone in the Fasteners are freely movable, but the claw and the bracket are kept flexible with respect to each other can be. This high level of flexibility is particularly important when it comes to initial heating of furnace systems required at the different due to the increasing temperature gradient Thermal expansion stresses in the ceiling and / or Sidewall construction can occur. Although under operating conditions mostly burn elastic sealing rings, the mobility in the screw connection remains maintained.
  • the invention proposes, among other things, to simplify assembly furthermore that the anchor stone in his head area has a recess that the area-wise recording a screw head or a nut of the Screw connection of the fastener is used.
  • the claw can be made of heat-resistant, ferritic or austenitic flat material, preferably Flat steel, be made by forming.
  • bracket according to the invention made of heat-resistant, ferritic or austenitic flat material, preferably flat steel, be produced by forming.
  • the spring plate made of spring steel consists.
  • the claw with an insulating mat is wrapped.
  • the invention is therefore based on the surprising finding Reason that ceramic anchor stones on hydraulic High-pressure presses, in any desired format, qualitatively high quality and inexpensive to manufacture.
  • the quality and durability of the holding device according to the invention is also surprisingly inexpensive the flexible use of the anchor stone in the fastener, in which he can move freely, via a spring and possibly elastic sealing rings, increased.
  • Fig. 1 are several holding devices according to the invention 1 shown installed in a ceiling 2 of a furnace.
  • the core of the holding device 1 according to the invention thereby an anchor stone 3, which is partially supported by a claw 4 is embraced.
  • the claw 4 is in turn one Bracket 5 attached to a metallic furnace wall 6.
  • the claw 4 is wrapped with an insulating mat 7, and the insulating mat 7 is in turn in one area Insulation 8, embedded over an insulating wool 9.
  • the Insulating mat 7, the insulation 8 and the insulating wool 9 run between the metallic furnace wall 6 and a monolithic liner 10 over one, on Train designed, adhesion on the anchor stones 3 and the fasteners 4, 5 stable on the metallic Furnace wall 6 is attached.
  • the ceiling installation shown in Fig. 1 can be as follows receive:
  • the anchor block 3 is made to size on hydraulic high-pressure presses manufactured, the concrete design the same with reference to Fig.en 5a to 7b described in detail is.
  • each fastener is still a spring plate 11 made of spring steel, the Meaning described in detail with reference to FIG. 8 is manufactured and selected a commercially available screw 12.
  • the metallic bracket 5 is attached to the metallic one Furnace wall 6 welded to form a weld 13, see Fig. 2b.
  • Holding devices 21 also for installation a monolithic liner 30 in a sidewall 22 use as shown in Fig. 3.
