  • the Heat shield elements are not easy to use independently of the supporting structure, but it must first a larger gap between the heat shield elements are formed, the sealing element can be used, the Gap are reduced and the heat shield elements finally be anchored to the supporting structure.
  • the invention is therefore based on the object of a heat shield arrangement for a structure carrying hot gas, in particular a metallic component of a gas turbine plant or Combustion chamber, with side by side on one Support structure anchored heat shield elements and a method for the production of such a heat shield arrangement specify which particular disadvantages described overcome, flexible use and particularly light and can be produced quickly.
  • the object is achieved according to the invention thanks to a heat shield arrangement with side-by-side coverage heat shield elements anchored on a supporting structure solved, in which at least two neighboring Heat shield elements each have at least one lateral, in Area of the edge of their surface facing the hot gas attached, have groove, these heat shield elements by means at least one sealing element introduced into the groove are connected and in which the sealing element as Sealing flap is formed, which from a first into a second position and vice versa, the first Position one open position with no sealing effect and the second Position is a closed position with a sealing effect.
  • a heat shield arrangement In a heat shield arrangement according to the invention, on the one hand the support structure before contact with the combustion chamber escaping hot gas is protected by the sealing element, which Gaps between the heat shield elements of the heat shield arrangement closes.
  • the sealing element As a sealing flap easy to manufacture and detachable because the sealing element when inserting or detaching a first in a second position or vice versa is so that when manufacturing the arrangement according to the invention the sealing element automatically from its first position (open Position) in its second position (closed position) is moved and when releasing the arrangement according to the invention automatically moves from its second to its first position becomes. That is, it is not necessary to manually seal the element to bring it into its second (closed) position or remove from its second position. Furthermore, it is possible to remove a single heat shield element without loosen the anchorings of adjacent heat shield elements to have to.
  • the sealing element by means of a movement of a heat shield element from the first to the second position and vice versa.
  • the Sealing elements not in a separate step in the inventive arrangement are introduced, but the Sealing elements move as a result of the movement of an insert Heat shield element automatically in its second (closed) Position without losing the anchorages of neighboring heat shield elements solved with the support structure must become.
  • the sealing element advantageously has a substantially C-shaped Cross section on.
  • Such a cross section of the Sealing element is particularly suitable because of this formed (longitudinal) slot particularly easy to hold the Sealing element can be used in the first position by for example the slot of the sealing element on the wall inserted in a groove and held in the first position becomes.
  • Sealing element designed as a curved plate.
  • the sealing element is particularly easy to manufacture when bent a plate is produced because a lot of raw materials in Form of plates are available.
  • the plate is advantageously made of sheet metal.
  • Sheet metal is characterized by its high resistance to Heat out, so that sheet metal as a sealing element in the invention Heat shield arrangement is particularly suitable. Furthermore, sheet metal is readily available, inexpensive and particularly easy to process.
  • the seal between the heat shield elements is automatically formed without a manual work step is necessary:
  • the one designed as a sealing flap Sealing element is automatically from its first (opened) moved to its second (closed) position, for example compressed and inserted into the groove advantageous in the manner of a rotary movement.
  • the squeeze of the sealing element improves the sealing effect when so "Prestressed” sealing element finally tight on the walls the groove is inserted into the groove and secures it the second position (closed position) of the Sealing flap to prevent it falling out of the groove.
  • FIG. 1 shows a heat shield arrangement 5 according to the invention shown.
  • the heat shield arrangement 5 protects a support structure 15 the destructive influence of hot gas, which in a Combustion chamber 10 is formed.
  • the heat shield arrangement 5 comprises heat shield elements 20, which all over the side on the support structure 15 arranged and on this by means of fasteners 35, for example screw connections are anchored.
  • the heat shield elements 20 each have at least one lateral, in the area of the edge of the hot gas Surface attached, groove 25 on. In the grooves 25 each Adjacent heat shield elements 20 is a sealing element 30 brought in.
  • the sealing element 30 is a sealing flap designed in this way, so that it can be moved from a first to a second position is, the first position is an open position without Sealing effect and the second position a closed position with sealing effect.
  • the sealing elements 30 advantageously have a substantially C-shaped cross section on.
  • the sealing elements 30 can be produced for example from a flat plate, which is preferably made of Sheet metal, and which is processed in this way by bending, that it has a C-shaped cross section.
  • Such C-shaped sealing flap has an elasticity that a resilient contact with the heat shield elements and a good one Seal allows.
  • the first position, not shown in FIG Sealing element 30 can be formed, for example, that a sealing element 30 with its, due to the C-shaped Cross-sectional (longitudinal) slot on the combustion chamber 10 closer edge of the groove 25 is held in where the wall protrudes into the slot (see figure 2b and 2c).
