Definitions

  • the invention relates to a roof tile compact with separating burr running around its outer edges and with two hook-in lugs which protrude downwards from the underside of the brick on the tile head, the separating burr serving as a brick covering when the standing compact is fired.
  • the excess clay material is separated off with the help of a so-called knife box, which creates the peripheral separating burr, which represents the outermost outline of the compact.
  • the roof tile compacts are inserted into a cassette, generally in such a way that they stand on one of their long sides, the separating ridge of this long side then representing the support.
  • This support is an essentially straight, narrow area strip which cannot guarantee that the compacts stand freely.
  • the compacts rather tilt in the cassette and lie obliquely on the cassette wall.
  • the individual roof tiles are supported against each other at the so-called stacking points. This contact can cause damage to the engobe or glaze if the bricks are separated again after the firing process. Due to the inclined position, warping can occur even at high firing temperatures.
  • the object of the present invention is therefore to design the roof tile compacts in such a way that they stand freely in the firing cassette and do not tip over and lie against one another even when the cassette is being transported.
  • the solution to this problem results from the characterizing part of the claim.
  • the separating ridge on the brick head side is designed so that it forms a secure support, preferably in the manner of a three-point support. This requirement ensures that the tile stands so securely that none There is a risk of tipping over in the cassette, not even in the case of impacts that are unavoidable when the cassette is being transported.
  • the top of the brick was chosen for this formation of the separating ridge, because here the measures mentioned do not impair the brick, ie there are no disadvantages when covering.
  • Fig. 1 shows a conventional roof tile compact, in a section parallel to the head side, seen from the eaves side.
  • the compact is designated as a whole by 10, and its head edge - located below the plane of the drawing - is indicated at 10a.
  • the compact 10 has two hook-in lugs 11 and 12 which protrude from the bottom of the brick at the bottom of the brick.
  • the head-side separating ridge is designated by 13, which represents the outermost outline of the brick head side and has the shape of an essentially straight strip parallel to the brick plane.
  • the compact 10 is inserted into a cassette for firing. If the brick 10 were to be placed on its top side, the separating ridge 13 would lie on the cassette floor as - as mentioned - the outermost outline. It is obvious that the compact 10 could not stand freely on this separating ridge 13, but would tip over. In general, the procedure is therefore that the compact 10 is not placed on its top side, but on one of its long sides; Although the separating ridges of the two long sides, which are not visible in the drawing, are essentially straight, narrow strips, at least the positioning height is then lower, which nevertheless cannot prevent the compact from tipping over and leaning against the cassette wall.
  • the compact 2 shows a roof tile compact according to the invention in the same view.
  • the compact is designated as a whole by 20 and its top edge by 20a.
  • the two hooking noses 21 and 22 are connected to one another by a strip-like part 23 to form a hanging strip.
  • the step-like separating burr, designated as a whole by 24, now differs substantially from the separating burr 13 of the compact 10.
  • the separating burr 24 has three ridge pieces parallel to the brick plane, namely the two ridge pieces 24a and 24b in the brick corners adjacent to the top of the brick, and the burr path 24c centrally adjacent to the lower edge of the hanging strip 21, 22.
  • Wire pieces 24d and 24e which are inclined to the brick plane, connect the parallel ridges 24a, 24b, 24c to one another to form the continuous separating ridge 24. It is obvious that this stepped separating ridge 24, the ridges 24a, 24b, 24c form a type of three-point support, the compact 20 offer a good hold when it is placed on its top side, that is, on the separating burr 24. The compact is the better, the greater the distance between the central ridge section 24c and the parallel line passing through the ridge sections 24a and 24b, the size of this distance, of course, being dependent on the particular brick model.
  • the top side of the brick is designed as a "stand” and not one of the long sides of the brick, which would be more obvious for reasons of standing height.
  • the roof tile compact according to the invention is free and does not tip over on its head side, so that there is no damage to the engobe or glaze and warping mentioned at the beginning.
