Definitions

  • the invention relates to a bridge-type industrial furnace support structure made of refractory ceramic bricks.
  • vaults and supporting arches of different span are created in order to create a furnace space, the vault or the supporting arch being overbuilt, for example, with refractory bricks.
  • the support sheet consists of two end bearing stones, which are supported on corresponding supports and a plurality of stones arranged therebetween, which each have a wedge shape to form a vault structure and each other via corresponding stages on their outer surfaces.
  • FIG. 1 shows a scheneatische representation of this furnace, partially cut away, with a plurality of such support sheets T, each support sheet is supported on the end of corresponding pillars P.
  • the WO 2009/053515 A1 describes stone vaults in building construction.
  • the US 6,017,487 discloses a circular furnace lid.
  • the invention leaves the known vault structures and suggests in its most general embodiment, a bridge-like industrial furnace support structure according to claims 1, 2.
  • each stone has at least one largely horizontally extending step.
  • “Largely horizontal” means that the step ideally runs horizontally in the mounting position, but may also be slightly inclined to the horizontal, with the corresponding inclination angle in each case being ⁇ 10 °, ⁇ 5 ° or ⁇ 2 °.
  • the steps in particular run continuously from a front end side of the respective stone in the mentioned embodiment of the support structure to a rear end side.
  • the support structure is suitable for spans (between end bearings) up to 3,000 mm, whereby for spans over 500 mm and in particular over 1,000 mm has a support structure has advantages in which between the capstone and each bearing stone at least one intermediate stone is placed, the intermediate stones in turn on their inside and outside again each have at least a largely horizontal, running stage.
  • the above-mentioned basic principle of the support structure is maintained, because even here are lying further inside the support structure stones in the area of the mentioned steps on corresponding stages of the outside adjacent stones, so that at a from above the supporting structure acting force this is passed down or outside in the bearing stones.
  • the horizontal contact surfaces of the stones create the possibility of compensating for expansions of the stones in the horizontal direction by parallel displacement of adjacent stones along the horizontal steps.
  • a sealing material for example a ceramic fiber seal, an elastic adhesive or a deformable mortar can be arranged both between the inner and outer surfaces of adjacent stones and in the region of the steps between adjacent stones.
  • the new design has the advantage over the cited prior art that a radial expansion of a support ring formed from a plurality of supporting structures is avoided.
  • the arrangement of the stones within the supporting structure is such that all stones form a common, largely horizontally extending top. This is important because often masonry is placed on the support structure. With horizontally running upper side of the support structure this is particularly easy and without filling materials or special formats of stones possible.
  • the stones within the support structure can also form a common, largely horizontally extending underside.
  • the term "largely horizontal” is not to be understood in the strict geometric sense, but also allows equivalent modifications or embodiments.
  • the corresponding surface portions of the stones may also be corrugated or profiled differently or formed slightly curved.
  • the geometry of the individual stones can be chosen so that at least one level of each stone lies with at least one level of another stone in a plane. It can also all stages within the support structure are aligned, so be arranged on a common plane.
  • the keystone may have a T-shape approximately in an end view (front view) and its lower section may taper conically towards the bottom of the support arch, although an embodiment with a constant cross section is possible.
  • the capstone has a peculiarity compared to the intermediate stones, because it has only two outer surfaces, each with at least one step.
  • capstone can also in the inventive solution analogous to the subject of the DE 39 33 744 to be divided vertically; However, this division would have no relevant technical function within the meaning of the invention and would only increase the number of components and extend the assembly.
  • the two end bearing stones have the peculiarity over the intermediate stones that only their inside is in contact with another stone of the respective support structure, while the outside of each jewel is either exposed or supported on an abutment.
  • an embodiment of the invention proposes to form the bearing stones, in an end view, approximately with an L-shape or mirrored L-shape.
  • the outer surface of each bearing stone can be substantially vertical, the inner surface can be outside the step (s) to the vertical at an angle> 0.
  • a single support structure can be designed so that at least one stone has a geometry in which the inside and the outside of the stone are not parallel to each other, so that the stone in plan view, for example, has a trapezoidal shape.
  • the narrower face can lie at the front or rear.
  • the support structure can also be designed so that at least one stone has a geometry in which the inside and the outside of the stone vetschen largely parallel to each other, so that the stone at least approximately has a rectangular shape in the plan.
  • any combination of stones of different shape are possible, for example: stones with trapezoidal shape, which tapers forward; Stones with trapezoidal shape, which tapers backwards; Rectangular stones.
  • stones with trapezoidal shape which tapers forward
  • Stones with trapezoidal shape which tapers backwards
  • Rectangular stones Rectangular stones.
  • joints in the plan view have a substantially constant width between adjacent stones, but also slightly wedge-shaped joint geometries are possible.
  • the support structure can also be designed so that the stones have at least one curved end face, so the stones are formed and arranged so that at least one end face of the support structure is curved.
  • a support ring is formed from a variety of supporting structures, wherein the inner Cylindrical surface of the ring is parallel to the cylindrical outer surface of the ring.
  • geometeries with planar stone surfaces front and / or rear are possible, which result in a polygonal course of the front and / or rear side of the entire supporting structure.
  • the supporting structure according to FIG. 2 consists of two outer bearing blocks (endstones) 10, 12, two intermediate blocks 14, 16 adjoining thereon on the inside and a central capping block 18.
  • the endstones In the end view (from the front and the back), the endstones have an L-shape (or mirrored L-shape), the intermediate stones an abstracted S-shape and the capstone a T-shape.
  • the outer bearing blocks have on the inside a horizontally extending step 10s, 12s, while the upwardly and downwardly adjoining sections of the inner sides 10i, 12i of the bearing blocks 10, 12 extend at an angle of about 10 ° to the vertical, and so on in that the jewels 10, 12 become wider from top to bottom.
  • the intermediate blocks 14, 16 with their corresponding steps 14as, 16as are located on the steps 10s, 12s, or more precisely: the intermediate blocks 14, 16 rest on a fiber mat which rests on the steps 10s, 12s.
  • the intermediate blocks 14, 16 also have on the inside a step 14is, 14is.
  • the steps 14is, 16is serve to receive corresponding steps 18s1, 18s2 in the area of outer surfaces, 18a1, 18a2 of the capstone 18th
  • outer sides 14a, 16a and the inner sides 14i, 16i of the intermediate blocks 14, 16 and the outer sides 18a1, 18a2 of the cap 18 extend outside of the steps substantially parallel to the inner surfaces 10i, 12i of the jewels 10, 12th
  • the support structure is self-supporting, although only the outer bearing blocks 10, 12 and these only partially corresponding to Resting on supports (pillar P).
  • top O and the bottom U of the support structure is largely planar in the illustrated embodiment and each extends horizontally. This applies analogously to the corresponding sections of the upper side O or the underside U of each individual block 10, 12, 14, 16, 18.
  • the inner steps 14is, 16is of the intermediate blocks 14, 16 run at different heights (namely, above) to the outer-side steps 14as, 16as, which promotes the dissipation of force.
  • FIG. 3 shows that all the bricks 10, 12, 14, 16, 18 in a view from below (also in a view from above) have a substantially rectangular base.
  • FIG. 4 is one of several, namely 11 supporting structures according to FIG. 2 to recognize educated support ring. Below the bearing blocks 10,12 run the supports (pillars) (not shown).
  • FIGS. 5 to 7 show details of different stones of a supporting structure. Only features which have not already been described in connection with the preceding figures will be mentioned below.
  • the capstone according to FIG. 5 has steps 18s1, 18s2 with a width (b) of about 100 mm each.
  • the already mentioned inclination angle a of the outer surfaces 18a1, 18a2 is about 10 °. While the front face 18vs and the rear end face 18hs are slightly curved respectively, the upper side 18o and the lower side 18u are substantially planar and substantially horizontal within the support structure.
  • the step 10s could also be slightly profiled, for example, slightly cambered executed.
  • a corresponding curvature would have the result that the step between the front and rear face of the stone would have a hill or mountain shape, with adjacent stones being adapted accordingly in their geometry.
  • the step would then, for example, have a certain radius, but would continue to be largely horizontal in the direction of the adjacent stone so as not to impair the desired horizontal displacement.
  • corresponding, corresponding tongue and groove geometries in the area of the steps of adjacent stones can also be formed, again without impairing the basically horizontal displaceability between adjacent stones.
  • the intermediate stone according to FIG. 7 is also characterized by planar top and bottom surfaces 14o, 14u and curved front and rear end faces 14vs, 14hs.
  • the width of each step 14as is again about 100 mm.
  • the steps 14as, 14is here are vertically offset from each other.
  • the inner and outer surfaces 14a, 14i correspond with respect to their inclination to the outer surfaces 18a1, 18a2 of the cap (sole piece) 18 according to FIG FIG. 5 ,
  • the invention comprises supporting structures which are designed mirror-inverted to a mirror plane which runs perpendicular to the longitudinal extent of the supporting structure (between the end blocks).
  • Such asymmetrical compositions of stones can be achieved by any combination of stones and are among other things advantageous for repair purposes.
