    Method based on being able to provide a double bottom in bathtub (1) cast marble so that the bathtub (1) has a reinforcing device similar to a single sandwich construction that increases the bathtub's strength and service life, and makes the bathtub much lighter. The reinforcement device is cast into the bottom (2) of the bath (1) and consists of an air-filled spacer (10) in glass fi reinforced plastic, adapted to the bottom structure of the bath (1). The design of the spacer molds (10) allows cast marble to effectively surface around the entire spacer mold (10) of the casting. With this method, the mass of cast marble can be reduced to almost half and thus also the weight to almost half. The cooling of the finished tub (1) takes place very quickly and can be removed from the mold fl times faster than with the previous manufacturing method, which reduces the manufacturing cost.

    It is therefore an object of the present invention to provide a method which in a simple manner solves many of the above problems. The method is based on being able to achieve a double bottom in a bathtub made of cast marble so that the bathtub has a reinforcing device similar to a sandwich construction that increases the bathtub's strength and service life, and makes the bathtub much lighter. The reinforcement device is poured into the bottom of the bathtub and consists of an air-filled spacer in glass fi reinforced plastic, adapted to the bottom structure of the bathtub. The design of the spacer mold allows cast marble to effectively surface around the entire spacer mold during casting.
    With this method, the mass of cast marble can be reduced to almost half and then also the weight to almost half. The cooling of the finished bathtub takes place very quickly and can be taken out of the mold fl times faster than with the previous manufacturing method, which reduces the manufacturing cost.
    Description An air-filled spacer in fiberglass-reinforced plastic is placed in the mold for the bathtub.
    The spacer mold is adapted to the bottom structure and the design allows cast marble to effectively surface around the entire spacer mold during casting.
    The mold is made in three parts which in the open state are coated with a gelcoat, which is allowed to dry, after which the spacer mold is inserted and the mold is closed and casting with cast marble takes place. Gelcoat is a thermosetting plastic used as a protective outer layer in the bathtub. It forms a glassy surface. The gelcoat is used to protect against moisture, UV radiation, mechanical surface damage and high temperatures. Gelcoat does not smell, does not bend and does not show any cracks. With the gelcoat you can get the desired colors on the bathtub and also different colors on the inside and outside of the bathtub. To place the spacer molds at the exact distance between the male and female of the mold, the spacer mold is provided with knobs that support the gelcoat when the mold is closed. Through this method of manufacturing the bathtub, another effect is also obtained, as one can use the void in the spacer form, to achieve e.g. a bubble bath. By drilling into the spacer shape in suitable places, you can get both a connection for air pump and holes for air discharge where the bubbles are to form. This means that the bathtub can be specially adapted to the customer's wishes about where the bubbles should occur, perhaps mostly under the back or mostly under the legs or shoulders. The method thus allows you to get a flexible bathtub, where you can later turn it into a whirlpool bathtub. An embodiment of the invention is described in the following and is illustrated in the accompanying drawing, which according to Fig. 1 shows a section through a marble-molded bathtub with no distance in the bottom.
    Fig. 2 shows a cut-out principle picture of how the spacer shape in glass fi annealed plastic is constructed- Fig. 3 shows a section through a marble-molded bathtub with a double bottom and how a whirlpool bath can be arranged.
    Fig. 4 shows a longitudinal section through a marble-cast bathtub with a double bottom and how the holes for the bubbles can be distributed.
    Method for manufacturing bathtubs according to figures 1, 2, 3 and 4 and may represent the construction form used in the example referred to here.
    Method for manufacturing a bathtub in cast marble according to fi Figure 1 shows a section through a marble-molded bathtub (1) with a molded-away spacer (10) in the bottom (2) of the bathtub (1).
    The spacer mold (10) forms a cavity (9) between the upper part (7) of the bottom, the side (4) of the bath (1) and the lower part (8) of the bottom. The bathtub (1) also has a strong upper edge (5) which provides extremely good stability for the entire bathtub (1) and facilitates handling when moving. The side (4) of the bathtub (1) is designed so that it functions as a base (3) in its lower part. The bathtub (1) is completely open (6) in its lower part under the base (3).
    Method for manufacturing bathtubs in cast marble according to Figure 2 shows a cut-out principle picture of how the spacer mold (10) in fiberglass-reinforced plastic is constructed. To place the spacer (10) at an exact distance between the male of the mold and the female, the spacer (10) is provided with knobs (13, 14) which support the gelcoat when the mold is closed. The spacer shape (10) is designed so that on the upper side it follows the same radius (11) as in the upper bottom (7) of the bath (1) and on the lower side the same radius (12) as in the lower bottom (8) of the bath (1). The spacer mold (10) forms a tower space (9) which extends over the entire bottom (2) of the bathtub (1). 10 15 20 25 30 Method for manufacturing a bathtub in cast marble according to Figure 3 shows a section through a marble-cast bathtub (1) with a double bottom and how a whirlpool bath can be arranged.
    By drilling into the empty space (9) of the spacer mold (10) in suitable places (17, 18), one can get both a connection for air pump and a hole (15) for air outlet (16) where the bubbles are to be formed.
    Method for manufacturing a bathtub in cast marble according to Figure 4 shows a longitudinal section through a marble-cast bathtub (1) with a double bottom and how the holes (15) for the bubbles can be distributed. This means that the bathtub (1) can be specially adapted to the customer's wishes about where the bubbles should occur, perhaps mostly under the back or mostly under the legs or shoulders. The method thus allows you to get a ibable bath (1), where you can later turn it into a whirlpool.
    Invention has been described in accordance with the preferred formulation and design, and it is to be understood that certain substitutions and modifications may be made without departing from the spirit. The example now described shows how the method is used for bathtubs in cast marble. Of course, the method can also be used in the manufacture of sinks or other structures in cast marble. Likewise, the spacer shape can be designed with a channel on the side of the bathtub, from the bottom and up to the edge of the bathtub. In this channel, hoses etc. can be placed. The example described above shows how a whirlpool bath can be arranged. In a similar way, a massage bathtub can be arranged by drilling into the void space of the spacer in suitable places, whereby one gets both a connection for a water pump and a hole for water exhaust where the water is to provide massage. A combination of a spa bath and a spa bath can also be achieved. The invention should thus not be taken as limited to what has been shown and described above, but such variants are included in the inventive concept and may be considered to be included within the scope of the appended claims.
