Definitions

  • the handling of the four screws enforces the use of fixatives such as bonding or adhesive tape, which are not reliable, so that the screws can be lost and must necessarily be found because of high risk of damage. Furthermore, no overhead mounting is possible, so that a considerable amount of time to position a large turbine assembly in the appropriate easy-to-assemble 6 o'clock position of the mounting station. In addition, it may be necessary for two people to install the last heat shield element as the four screws must be inserted into the corresponding four holes in the support structure. Last but not least is to consider that the screws are relatively expensive because of the highly heat-resistant alloy used and must be replaced with new ones at each dismantling because of high safety requirements.
  • a recess provided with a through hole in a corresponding hole for piercing the heat shield plate, in which the fastening screw is pushed, the head of the fastening screw in a through the recess and the carrier plate facing side the heat shield plate trained space is locked.
  • the fastening screw can not be lost.
  • the carrier plate has at least one groove which has a common groove base and a narrowed region forming the open groove side.
  • the means formed in the holding element for engaging in the holder grooves of the heat shield plate are preferably designed as gripping sections.
  • the holding element may further comprise a fixing portion serving as a retaining spring, the width of which corresponds to the width of the narrowed portion of the groove of the carrier plate.
  • the thickness of the heat shield plate and the thickness of the support plate preferably give a total thickness of the two-part heat shield element according to the invention, which corresponds to the thickness of a one-piece ceramic heat shield element.
  • pocket CHS pocket stone
  • the retaining element 7 is embedded in the support plate 5.
  • the intended for receiving the retaining element 7 groove 6 of the support plate 5 is formed in a projecting toward the cold side Vorstreckung
  • This Vorsteckung 13 forms a guide rail 13, preferably one on each side of the support plate 5, which is inserted into the respective groove 15 of the support structure 16 and the support plate 5 with the mounted on her heat shield plate 10 allows accurate positioning and alignment.
  • the grooves 15 in the support structure 16 need not be introduced specifically for the heat shield element 1 according to the invention in the support structure, but are usually already provided for the assembly of the normal one-piece ceramic heat shield elements using the identical holding elements 7.
