Definitions

  • the present invention relates to shower trays and to methods of manufacturing the shower trays, particularly to methods using a mounting frame when mounting the shower tray.
  • shower trays commonly referred to as extra-flat trays, the thickness of which, measured at one end of the shower tray, for example, is comprised in a range between 20 and 40 mm, has increased in recent years.
  • shower trays of this type comprise a thin top slab comprising a thickness between 3 and 20 mm, and an inner body adhered to said outer surface which imparts the necessary robustness to the top slab.
  • shower trays of this type can be manufactured directly on site, in which case it is necessary and indispensable to create a base in the floor that slope towards a drain point, and to subsequently level and waterproof the floor and walls before the final coating, and the skill of the construction worker is of vital importance in these cases to avoid possible water leakage, or they can be prefabricated so that they can be readily placed in their final location.
  • ES2582681 A1 describes a prefabricated extra-flat shower tray comprising a top slab formed by a sintered ceramic sheet and an inner body adhered to said top slab.
  • the ceramic sheet is curved, with the aid of a mounting frame, so as to provide the necessary camber.
  • the mounting frame comprises a perimeter frame and two cross-shaped bars with variable thickness, the perimeter frame being arranged in the lowest position.
  • the ceramic sheet is arranged with its usable surface supported on the mounting frame and its edges are pressed so that they contact the perimeter frame. With the sheet in that arrangement, a layer of resin is applied, which will form the inner body of the shower tray when hardened and will preserve the curved shape of the sheet.
  • the utility model DE202017003602 U1 discloses a shower tray comprising a top slab being formed from four trapezial plates, an inner body adhered to the bottom of the top slab and a central part arranged between the top slab and the inner body, each trapezial plate converging in said central part.
  • EP1181883 A1 describes a frame supporting the edges of a shower tray comprising feet and an arm for supporting the siphon.
  • DE102016108128 A1 discloses a mounting frame for shower trays made of enameled steel sheet.
  • the shower trays comprise a drain opening and at least on one side a flat edge for engaging in a groove of the mounting frame.
  • DE102006007471 A1 describes a shower tray comprising a top slab cambered towards a central hole and an inner body adhered to the top slab.

The transverse bars are slidable along the longitudinal bars and they can be locked at any point of the longitudinal bars. Both the longitudinal bars and the transverse bars each comprise at least one channeled segment which allows completely or partially housing an end of a corresponding trapezial plate, preferably the widest end.
  • the mounting frame also comprises a bottom support arranged at a lower level of the perimeter frame, such that the trapezial plates converge in said bottom support, thus defining a camber of the shower tray and the final shape of the shower tray such that the assembly mounted on the mounting frame remains compact and secured while acting or working on said assembly.
  • Another object of the invention is to provide a method of manufacturing a shower tray, as defined in claims 7-14.
  • the method of manufacture comprises a first step in which the top slab of the shower tray is obtained and a second step in which the inner body is obtained.

  • the trapezial plates converge in the bottom support arranged at the lower lever of the perimeter frame, thus defining a camber of the shower tray.
  • the method of the invention also comprises an overturning step which is carried out during the first step so as to have access to a bottom face of the top slab, attaching and tightly sealing the trapezial plates to one another, both by the top face and by the bottom face of the top slab, with these being mounted on the mounting frame.

  • decorative strips not shown in the drawings could be placed on the inner perimeter of the casing, said strips preferably being of the same material as the top slab 1, improving the finish or appearance of the inner body 2.
  • the inner body 2 may comprise a reinforcement mesh 7 embedded in its interior.
  • said mesh 7 can be placed on the bottom face 12 of the top slab 1 before pouring the material 15.
  • said mesh 7 may comprise a hole to allow the placement of the drain system of the space. Said hole can be housed in the central depression 6b of the central part 6 if the shower tray 200 comprises said central part 6.
  • the mesh 7 provides additional reinforcement to the area close to the drain point, which is obviously the most delicate area of the shower tray 200, so this area can be doubly reinforced, providing great structural stability.
  • the mesh 7 Before pouring the material 15, the mesh 7 may or may not be adhered to the bottom face 12 of the top slab 1. If it is to be adhered to the top slab 1, the mesh 7 can be placed before disassembling the top slab 1 from the mounting frame 100.
  • the mesh 7 is made of metal, although it could also be made of plastic.
  • the formwork is dismantled at the end of the second step, once the material 15 forming the inner body 2 of the shower tray 200 is set or cured, the shower tray 200 being ready for use.
