are at least 1.587 mm (16 gauge) thick and they have a siliconized surface so that the terrazzo tiles do not adhere.During use, this silky-smooth coating is particularly exposed through repeated heating and cooling, as well as the abrasion caused by the crushed stones the plates that are closer to the end of the mold, where the mild steel plates tend to become porous and therefore adhere to the terrace tiles, making them rough. So that the river steel plates do not become porous, at least for a certain period of time, they can be flattened with a metal that has a lower tendency to become porous «like cadmium It was decided to use cadmium-plated mild steel plates only for the outermost h plates of each end of the mold. The invention also relates to a method for the production of synthetic resin-bonded terrace tiles in a form of the invention, whereby the components of the terrace tiles, apart from the crushed stones (in the The mold is poured and while the mold is vibrating, the crushed stones are gradually added.Then the synthetic resin is hardened without reducing the pressure and then the terrazzo tiles are removed from the mold.To maintain the homogeneous quality of the terrazzo tiles near the ends the Fora, it is desirable to have the end plates of the form e.g. u Insulate in order to reduce the radiation of heat that is generated when the synthetic resin hardens.This insulation can be achieved with the help of a sheet made of linoleum or similar insulating material be critical of the invention.

As the weight and number of molds and accessories used Any time, the weight, the horror and the rigidity the tray on which the molds rest on the vibrator, as well as the force and natural frequency of the vibrator aotora säatlioh have an immediate effect on the quality of the vibration «the actually transferred to the fora, it is not possible to be exact Specify values for a satisfactory vibration · However, this can be determined by preliminary tests, insufficiently vibrated tiles «own voids, in which dirt would accumulate and which makes the tiles unsanitary will. Tiles that are vibrating too much will move towards the center darker, as the components have to be separated, and this is how they become more fragile "

Preferably, the entire components of the tiles are poured into the mold, with the exception of the crushed stones, so that the outer tile spaces preserved about twice as much as the inner trees. You in between lying rooms receive a medium amount. Thereupon the crushed stones are preferably initially predominantly on the outer ones Tapes of all tile scrapers are added until the material is on the Surface of the form appears. If there is material from the fuller Flleeenräuaen overflowed into the emptier rooms, the crushed ones become Stones poured onto the fuller, i.e. the outer tile rooms, and are spread e.g. with a trowel so that the openings in the Tile clearing practically always covered with liquid «1 * 4 · As soon as all Tile rooms are filled, i.e. after about half a stand, the Mold removed from the vibrator and the resin hardened ο Baoh dem When hardening, the mold is opened and the tiles are removed · It is only necessary “relatively little” cleaning “before the mold

«Leather is assembled for further use. Ee must consider must be seen «that the upper edge of the tiles produced is not of the same quality as the other edges of the tiles» the upper one Edge is usually sawn off * The sharp edges of the tiles can be beveled slightly and the surface can be sanded and, if necessary, filled to remove any voids

You can use tiles on any subfloor without any special pretreatment laid with the help of an adhesive and sanded in situ and poured in.

Natural stones or synthetic stones can be used as crushed stoins or any aggregate, e.g. marble, barite or resin used be. They are preferably aged practically the same through a sieve Sieved mesh size. However, the openings of the sieve should not be greater than the thickness of the terrazzo tile to be produced "

An example of a mold according to the invention is explained in the drawings, in which Figure 1 shows a representation of the mold and its parts in an exploded arrangement. Figure 2 shows the assembled one Form and Figure 3 shows the improved implementation form Assembling the shape of Figures 1 and 2 in a web of welding materials, among other things to harden the synthetic resin.

With reference to the drawings, 1 denotes the plates, 2 the spacers, 3 the screw bolts, k the indeplates of the shape and 5 the side brackets of the container.

A method according to the invention will be described in more detail below wrote «to earth. There are the trade names and the information des Kersteilere for the materials actually used. A format is used as explained in the drawings.

17 plates of mild steel with a thickness of 1.587 mm (16 gauge) are coated with a liquid silicone skin (manufactured by ICI under the designation H206 _v ). Dipping or spraying silikoniaiert and baked mindestena 2 hours at 200 ⁰ C and a long "" allowed to cool * It forms a layer of about 3I O, O5O8 mm 8tärke. Then a release agent is on a 3asis Silikonwachse3 applied The plates are assembled with similarly treated spacers having a thickness of k, 8 mm into a shape as illustrated in the drawings on the surface of the plates. The mold is placed on a vibrator.

A polyester maize is made according to the manufacturer's instructions. Scott Bader & Co h01 posed. Eo will be the following materials

The resinous mass is poured unevenly into the mold, so that the outer tiled areas contain more than the inner tiled areas which contain practically no powder, the form is mainly on the outer bands of all tile spaces. The material appears on the surface of the mold first in the tile spaces which contain the larger amount of resin mass. "The addition of the crushed stones is continued in this area, and the terrazzo tiles are allowed to flow over the fuller tile spaces into the less full trees. As soon as the crushed stones have been completely added, the tiled areas are filled with a homogeneous terrazzo tile mass and a small amount of the resin mass remains on the surface. The process is preferably carried out at a temperature of 10 to 16 ° C. Above 16 ° C the hardening proceeds too quickly, while below h ° C the reaction proceeds too slowly

809811/0986

The fora is then heated to 38 ° C for about k hours. As the hardening progresses, heat and pressure develop in the flieara, which makes them uniform and strong. «Lbat τοη d« r fora can be read.

The form can then be opened and the flow can be opened read air flow off «dry remain«

Another way of using the result in Figure 3 of the drawings is explained by the four plates at each end, the old Cadaiaa plates. All other factors and conditions and the same. The time when the fora is only open is reduced from 15 minutes to one minute and the time for cleaning the fora as well as work is reduced from 2 hours to a few minutes If you can cure terrasao tiles wisely within h hours instead of at least 6 hours as originally assumed, the working time is reduced from 8 to 4 1/2 hours.

Finally, you can saw off the top edge of the terrace tiles and Somewhat · Fill voids · The surface of the terrasao tiles can ground «ground and off. Traneport will be the Füesea la general bundled on their support side.

The terrace slabs can be sanded in such a way that they cannot be removed and then thoroughly cleaned. Since the material of the
