Definitions

  • the invention relates to a method for the production of cladding elements, in particular roofing tiles or outside wall cladding elements, made from a hardenable plastic mass, comprising:
  • the advantage of it is that with relatively great production capacity a large stream of cladding elements can be produced.
  • the bottom face of the elements in the known method is formed by the bottom of the moulds and the top face of the elements is an extrusion face.
  • the ready elements will overlap each other on a sloping roof or on an outside wall in such a way that a shoulder is visible at the position of the overlap.
  • a need has become apparent for tiles and outside wall cladding elements which can form a watertight clad surface by means of overlap wings without said overlapping shoulders being visible.
  • the absence of overlapping shoulders produces an aesthetic advantage.
  • the object of the invention is to provide a method of the type mentioned in the preamble by means of which cladding elements which can form a watertight clad surface without visible overlapping shoulders are produced.
  • the method is characterized in that
  • the method has the advantage that the visible face of the elements can be made of any conceivable shape, a flat face often being preferable.
  • the invention gives the possibility to cover the bottom of each mould by a plate of plastics material, stainless steel or ceramic material before the plastic mass is fed into the mould, said plate becoming attached to said mass.
  • each mould is provided with a pattern of ribs and/or grooves.
  • Figure 1 shows a perspective view of the top side of the cladding elements obtained by the method according to the invention.
  • Figure 2 shows a perspective view of the bottom side of the element according to Figure 1.
  • Figure 3 shows a cross-section through two cladding elements connecting to each other.
  • Figure 4 shows a cross-section through a part of a sloping roof clad with roofing tiles according to the invention.
  • Figure 5 shows a schematic view of the production process in cross-section.
  • Figure 6 shows a number of possible top views of the cladding elements according to the invention.
  • the cladding elements shown in Figures 1 to 4 for a roof or outside wall have at the top side (see Figure 1) a visible face 1 (which is the face remaining visible after fitting of the elements), an overlap wing 2 for the lengthwise overlap and an overlap wing 3 for the transverse overlap. At the bottom side (see Figure 2) an overlap wing 5 adjoins the bottom face 4 for the transverse overlap.
  • Figure 3 shows how two elements overlap each other in the lengthwise direction: the bottom edge 1a of the next element rests on the overlap wing 2, the thickness (p) of said bottom edge 1a corresponding essentially to the height (q) of a shoulder 6 forming the division between the visible face 1 and the overlap wing 2.
  • the thickness (s) of an element at the position of the shoulder 6 is greater than the thickness (p) of the bottom edge.
  • the visible faces of the elements lying one above the other can form a shoulderless flat face.
  • a wing 3 of the elements following one another in the transverse direction always rests in such a way on a wing 5 that said flat face is not interrupted by a shoulder or projection.
  • Figure 5 shows that a plastic mass is placed on a row of moulds 8, moving continuously or batchwise in the direction of the arrow, by a feed device which is known per se, and which comprises a supply tank 9, a rotary distribution and pressure impeller wheel 10, a scraper 11, and a rotary shut-off roller 12 placed between the scraper 11 and the tank 9.
  • a feed device which is known per se, and which comprises a supply tank 9, a rotary distribution and pressure impeller wheel 10, a scraper 11, and a rotary shut-off roller 12 placed between the scraper 11 and the tank 9.
  • top face of the ready elements which is the face shown in Figure 1
  • bottom face of the ready elements shown in Figure 2 is an extrusion face determined by the shape of the edge of the scraper 11.
  • the mass deposited on the row of moulds is divided into pieces by knives 15, the length of which pieces corresponds to that of the moulds 8.
  • the elements formed are given the opportunity to set. If the plastic material is made of concrete material, the setting takes place by itself. In the case of a ceramic mass the elements will be dried and baked in an oven. A hardenable plastic material is also one of the possibilities.
  • a fixing hole 13 can be provided in the elements.
  • the overlap wings 2, 3 and 5 can be provided with channels 14 or corrugations which can improve the drainage of any leaking water.
  • the visible face of the cladding elements can be made of any desired shape and that, despite that, the elements can be produced in a continuous process with great production capacity.
  • the height (q) of the shoulder 6 is made approximately equal to the thickness (p) of the bottom edge of the elements, it is possible to obtain a roofing or outside wall cladding without visible overlapping edges. It is possible to dispense with the use of battens and tile laths on the roof boarding of a sloping roof.
  • each mould could be covered by a plate of plastics material, stainless steel or ceramic material before the plastic mass is fed into the mould.
  • the plate will adhere to or becomes attached to the mass.
