WET SPACE ELEMENT AND METHOD AND APPARATUS ELEMENT

PREPARING

The invention relates to a seamless wet space element, such as a bathroom element. The inner surfaces of the element are mainly tiled. Tiling is performed on separate platforms first into tile planes, which are installed in place in the rotatable element mold. The parts of the element are attached to the mold by means of a vacuum.

Seam-based wet room elements are already known, the inner surface of which is made of plastic-coated sheet metal or reinforced plastic and the floor parts tiled or of plastic mat. It is still known to use heavy prefabricated elements made of concrete, the walls of which, however, are cast separately. Tiled wall elements are known from DE 2460960 and 3110040. A seamless bathroom element is known from SE 305 306, in which a sturdy plastic shell also acts as the body of the element. The shell is finished afterwards.

However, there is no wet element in the market, which is mainly seamless, tiled on the inside and manufactured in series as a serial product with as little manual work as possible.

The wet space element according to the invention, its manufacturing method and manufacturing devices present a surprising solution for eliminating the current drawbacks and shortcomings. The invention is characterized by what is stated in the appended claims.

The most important advantages of the invention can be considered the acceleration of tiling, the ease of handling of the element due to the properties of the mold, the variability of the mold according to the size of the element and the strength of the resulting element. The element becomes seamless because the tiles are bonded together with a thermoplastic type binder, which is applied with a waterproof layer to the back surface of the tiles and the binder with possible reinforcing materials forms a seamless layer at least on the floor and walls. Typical thermoplastic binders include polyesters, epoxies, phenolic and urea formaldehyde resins. Further, the outer layers of the element can always be attached in the most preferred position of the mold and to make the outside of the finish.

In the following, the invention will be explained in more detail with reference to the accompanying drawing, in which Figure 1 shows a tiling substrate.

Figure 2 shows a sectional view of the tiling situation.

Figure 3 shows the connection of the tile planes to the mold surfaces. Figure 4 shows a side view of a rotatable mold.

Figure 5 shows the connection between the floor and the wall.

Figure 1 preferably shows a tiled pallet 1 which can be moved. A grid surface is formed on the substrate for a certain tile size, with platforms 2 which guide the placement of the tiles in both the longitudinal and transverse directions. The tiling starts from the edge of the base, where the sliding beam 4 is placed. Slab stacks 3 are placed in the intermediate spaces of the intermediate guides 6 of the sliding beam, where the slabs 7 face upwards. The calculated number of tiles is placed in the stacks depending on the wall dimensions or the number of tiles in the stacks is maintained by some tile feeding mechanism. The push bar 4 is pushed over the base at one end. In this case, the lower plates of the stacks 3 are each placed in the right place on the base. No tiling takes place during the return movement of the push bar. The side guides 5 at the ends of the push bar guide the bar 4 sideways. ____

Figure 2 is a sectional view of the placement of the tiles in their raster spaces on the substrate. The rear edge of the sliding beam 4 is at a suitable height, so that it pushes even the lowest slab but allows it to fall into place when it collides with the raster platform 2. By swiping the sliding beam 4 over the base, the slabs are placed in place. At this stage, with the tiles on the substrate, the tiles are sealed by filling the butt joints between the tiles with sealant.

Figure 3 shows an embodiment of an assembly line in which each wall and floor of the element has its own transfer base 1, which are stored in the stack 14 shown in step 1. The tiling and sealing of these parts has already been carried out. In step 2, a tiled plane comprising the wall of the element is taken on its base 1 and placed under the mold. By raising the base 1 or lowering the mold, the tile plane and the mating surface of the mold are brought into contact. The mating surface of the mold consists of suction cups of one or more per plate. By applying a vacuum or a corresponding pressure difference to the suction cups, the base 1 can be removed and the plane formed by the plates 7 is transferred to the surface of the mold. All four wall blanks are transferred to the mold in a similar manner, rotating the mold in between. In step 3, the floor portion 12 is also connected to the mold. The floor portion 12 comprises one row of tiles 15 in the direction of the wall. When the walls and the floor are mainly in the form of tiles only, a layer of binder is applied to their outer surface. An injectable or spreadable resin is used as the binder, and fiberglass is typically used as the reinforcing agent. Thus, a waterproof seamless layer is formed immediately on the back surface of the tiles and at the same time the tiles are bonded together. By rotating the mold, all surfaces can be made in the most advantageous position.

A layer of core material, for example hard mineral wool, polystyrene or polyurethane sheet, is added on top of the waterproof layer. On top of this, an outer lining is made of reinforced plastic, sheet metal or sheet material, rotating the mold also to the most advantageous position. Once the structure is strong enough, it is removed from the mold for finishing. In this case, e.g. roof. Pipe installations are made either inside the wall frame to the core material layer or outside the wall frame, and in connection with the finishing, the required amount of furniture is added inside the element, after which the element is ready to be transported to the place of use.

Figure 4 shows a mold version in which the circular circumference 8 rests on rollers 9 in the support legs and a vertical roller 18 at the height of the lower edge of the circumference, which ensures the stability of the circumference 93668 4 8 and which also rotates the circumference. A mold body is built on the perimeter 8, comprising fixed beams 11 on which the horizontal beams 17 determining the size of the element can be slid. The horizontal beams 17 are also adjustable in the other direction, as their attachment point can be further moved in the sliding beams 16 shown in the figure. illustrates a surface formed of rectangular tubes 22 with suction cups 23 mounted upwards on said tubes. At the ends of the pipes 22 there is a collecting pipe 20 and a connection 21. Through one 21 the vacuum is allowed to act on the suction cups. The beams 19 are supported by the pipes 22. The sliding of the beams 17 in the beams 16 and the sliding of the beams 16 in the beams 11 are realized by means of mechanical motors and screws or by means of hydraulic or pneumatic cylinders. It is also possible to carry out the lifting and lowering movement of the rollers 9 on the support legs 10, as well as the horizontal movement of the support legs themselves, e.g. along rails on the floor. The mold can be contracted and expanded within the limits allowed by the circumference 8 according to the floor area of the element. The height of the element is usually constant.

Instead of suction cups, self-adhesive and detachable members, such as sticker-type members, can be used as a result of the contact.

Figure 5 shows the connection of a floor element provided with one row of wall tiles 7b to a wall element. The floor element comprising the lowest row of tiles 7b in the wall is made by laminating a layer of reinforcing plastic 27 outside the tiles. The binder and reinforcing material 28 of the actual wall element are overlapped on the lamination of the previous floor element, thus achieving a seamless connection. If necessary, a core material 24 is added to the wall sections, such as a hard mineral wool, polystyrene or polyurethane sheet, which is covered with an outer lining 25. The outer lining can be a lamination, a sheet metal or e.g. a sheet metal. The lower part of the wall is surrounded by a galvanized sheet metal 26, the edge of which also extends between the vertical lamination.
