Definitions

  • the invention relates to a composite system of refractory ceramic sieves for forming a volute-like support structure.
  • a gewöSbemé support structure according to DE 39 33 744 C2 is located in the burner area of a lime kiln. It consists of Figure 1 - in a view from the front (simplified below: in the Y direction of the coordinate system) - of several (simplified below: in the Z direction of the coordinate system) stacked, arched stone rows 14,16, each stone row turn from several, side by side (simplified below: in the X direction of the coordinate system) running stones.
  • the alignment on the coordinate system ( ⁇ , ⁇ , ⁇ ) is assumed below analogously (mutatis mutandis) for the individual stone of the supporting structure.
  • the juxtaposed in the X direction stones are positively connected with radial, ie in the Z direction grooves and springs.
  • a specially shaped capping set is inserted in the Y direction in the middle between two opposing sections of a row of stones to close them.
  • the invention is based on the object, an alternative laying technique
  • the invention is based on the following considerations:
  • the invention provides to form the stones with two mold elements in the X and Y directions, which simultaneously stabilize the composite in the Z direction. This allows the stones in one
  • the invention relates to a composite system of stones which are arranged in mutually perpendicular rows next to each other, in the X direction, and in succession, in the Y direction so that they together form a vault-like support structure, wherein more than 90% of Stones have the following shape:
  • the front side and the rear side are formed with corresponding profilings which result in a positive connection between a back side of a stone and a front side of an adjacent stone following in the Y direction,
  • the inside and the outside are formed with corresponding profiles, which result in a positive connection between an outer side of a stone and a following in the X direction inside of an adjacent stone.
  • the vast majority of the stones within the bridge-like supporting structure consist of identical stones
  • Other stone formats and / or stone geometries should be limited to the structurally necessary areas, for example, the end bearing of a vault arch.
  • a suitably adapted stretchset can be used in the middle, which consists of stones of other formats.
  • more than 95% of the bricks of the composite system can be designed in the manner according to the invention.
  • the profiles mentioned each extend in one direction of the
  • Coordinate system (X, Y) between opposite sides / edges of the stone that is, there are no discrete profiles that project centrally from the surface or centered in the surface.
  • At least one profiling of a stone is designed in the manner of a spring, while the corresponding profiling of the stone (on its opposite surface) is carried out in the manner of a corresponding groove. Accordingly spring and groove extend again over the entire distance of opposite stone edges.
  • the spring and the groove of the stone may be arranged eccentrically in the Z direction.
  • tongue and groove are closer to the bottom of the stone than the top.
  • the size of the grooves and springs is usually not crucial. Tongue and groove, however, should have a certain minimum size to ensure the mechanical stability of the form-locking connection for a long time. Therefore, it is provided according to a variant that the groove and the spring of the stones in the Z direction over at least 20% of the height of the stone in the Z direction.
  • profiling is that of a step, wherein the corresponding profiling of the stone (on the opposite surface) consists of a corresponding step, so that the desired form-fit can be achieved again between adjacent stones.
  • the steps may in turn be positioned off-center in the Z direction of the brick, for example the top of the brick closer than the bottom, while extending in the X or Y direction over the entire distance between opposite edges / sides of the brick.
  • the profilings on the inside and the outside as well as on the front and the back of the stone at least partially at an angle not equal to 90 ° to the respective
  • a further modification provides to arrange the profiles on the front and back of a stone in the Z direction offset from the profilings on the inside and outside of the stone. This "staggered" arrangement of the mutual profiles on a stone contributes to the equalization of the load distribution in the assembled state.
  • the stones can be arranged in the same direction or in opposite directions in two sections.
  • Figure 1 a perspective view of a stone designed according to the invention
  • Figure 2a an end view of the back RP (N) in the Y direction of the stone after
  • FIG. 1 A first figure.
  • FIG. 2b shows a side view in the X direction of the stone according to FIG. 1
  • Figure 3 a view in the Y direction on a vault-like support structure
  • FIG. 5 shows an enlarged view of the right end of the support sheet according to FIG. 3
  • FIGS. 2a and 3-5 schematically show a ⁇ , ⁇ , ⁇ coordinate system.
  • the stone shown in Figure 1 has an inner side I, an outer side A, a front side V, a back side R, an upper side O and a lower side Ii.
  • a profiling IP is to be recognized as a step ST1
  • a corresponding step ST2 is provided as profiling AP, wherein the profilings IP, AP extend over the entire length of the stone, ie between opposite edges K1, K2 of the stone.
  • 46 stone rows S1 .... S48 can be seen schematically, which are arranged next to one another in the X direction and consist of successively arranged stones SU, S12 .... S26.1, S26.2 ... in the Y direction. Stones SU, S2.1 of adjacent rows (S1, S2) are offset in the Y direction from one another.
  • the stones of adjacent rows of stones S1 .... S46 are positively connected to each other via the steps Sil, ST2, while the stones of a row of stones, for example S2, in the Y direction one behind the other via Nul / spring connections N, F Formschiuss to each other.
  • the stones taper slightly between top O and bottom U, so that the can-like support structure according to Figure 3 can produce positive fit.
  • the arch-like support structure rests on end stones E which are not described in more detail.
  • the supporting structure can be set up in the X and Y direction in the combination of the described stones.

Abstract

L'invention concerne un système sandwich composé de pierres céramiques ignifuges permettant de réaliser une structure portante du type voûte. Selon l'invention, les pierres sont formées avec deux éléments à complémentarité de formes dans les directions X et Y, lesquels stabilisent simultanément l'ensemble dans la direction Z. Cela permet de disposer facilement les pierres pour former un ensemble continu dans les directions X et Y, mais également dans la direction Z du système de coordonnées.
