Definitions

  • the invention refers to a method for the production of angled concrete roofing tiles, with the aid of an angled profiled under mould, which must form the underside of the tile and which will be placed in a worktable.
  • roofs whereby in one roofside different pitches of the roof are in line with each other, one uses so-called angled roof tiles.
  • These roofs e.g. mansardroofs are much less in use with modern building methods, but with renovation of existing roofs they appear frequently.
  • connection between the two different roofpitches in other ways, e.g. with a profile in zinc, preference will be given to a continuous roofcovering, whereby the angled roof tile is used. This solution is better looking and besides cheaper too.
  • the invention intends to create a method, which facilitates a more mechanized production with small investments, with as advantages a better product with lower labour costs.
  • the method according to the invention can achieve this in that the upper side of the roofing tile will be formed by a profiled roller rotating around a horizontal axis, which axis is moved parallel to itself at a certain distance from the mould, following the angled shape of the mould.
  • the invention refers also to the apparatus for carrying out this method, comprising an angled and profiled undermould places in a worktable, which apparatus is characterized in that a profiled roller rotating around a horizontal axis, is placed in one end of a balance, of which the horizontal tilting axis is movable over a fixed flat plane, while the other end of the balance will be guided by a guiding rail containing two inclined straight parts.
  • the angled roof tiles 1 (fig. 1 and 2) have an inclination angle (fig. 2), which usually is less than 180°, but can also be more than 180°, thus having an angle upwards instead of downwards. This would not be a mandardroof, but a leanto roof like with farmbuildings or similar.
  • the apparatus will produce with little effort and costs angled roof tiles with other angles, provided the moulds, on which these angles roof tiles are to be made, are of the right model and form.
  • the apparatus according to the invention exists of a worktable with placed on it a profiled mould 2, which forms the underside and the edges of an angled roof tile 1 to be produced.
  • the profiled mould 2 will have the same shape as the connecting planes 3 and 4 of the worktable. These planes 3 and 4 will be profiled like the surface of the mould 2, but these planes taper gradually to the surface of the profile of the tile 1.
  • the compaction of the mortar is carried out in a similar way as the normal concrete roofing tile production, namely with a rotating profiled roller 5, but without the extrusion profile (slipper) as used in normal production of concrete roofing tiles.
  • This profiled roller 5, of which an embodiment is shown in fig. 6, can rotate in both directions, also depending on the direction of movement over the tile 1.
  • the profiled roller 5 driven by a motor is part of a mobile mechanism, which means the roller 5 is placed at the end of the - balance 6.
  • This mobile mechanism moves over a set of rails 7, on which a set of wheels 8 rests.
  • In 8 we find also the turning point of balance 6 and at the other end of the balance 6 we find a set of guiding wheels 9.
  • These guiding wheels 9 guide the position of the profiled roller 5 via a curved rail 10, of which the deepest point corresponds with the highest point of the angled tile 1.
  • the profiled roller 5 will be pressed onto the tile to be shaped, via the guiding wheels 9, in such a way that a sufficient compaction in a correct profile height and shape is obtained, provided there is enough mortar placed on the areas to be compacted.
  • the movement of the set of wheels 8 will be made by means of hydraulic or pneumatic (double action) cylinders, spindle motor or direct drive (not indicated on the sketches).
  • the mechanism Starting from the begin position (fig. 3) the mechanism will move to the position according to fig. 4 and further to the position according to fig. 5.
  • the places, where mortar has to be added become clear and after about 3 cycles in both directions together with the necessary mortar additions, the angled roofing tile is ready.
  • a handle on both sides of the roller 5 is placed, while the roller 5 is protected on its topside by a hood. If one presses the handle, the drive of the profiled roller 5 will stop.
  • the angled roofing tile 1, now cut free, will be lifted out of the worktable together with the mould, either with hydraulic or pneumatic cylinder, or by means of a mechanical,lever.
  • the angled roofing tile 1 will be carried off for further eventual finishing (e.g. finishing with slurry and granules) and curing.
  • finishing e.g. finishing with slurry and granules
  • curing e.g. curing.
