Definitions

  • the present invention relates to a plate-shaped shaped block and a method for its production.
  • Slab-shaped shaped blocks are essentially produced using three different processes: First, there are ceramic-made products in which the slabs are formed from a ceramic mass and then fired. The molded parts must be oversized due to the shrinkage when burning. These shaped stones are very stable and allow for many different designs, including color and shape. However, their production is economically unfavorable and expensive, for example because of the varying shrinkage and the high energy expenditure during burning. Secondly, shaped stones are known that are bound by synthetic resins. However, their production is expensive because of the high cost of synthetic resins. Because of their high UV sensitivity, these shaped stones are not suitable as facade materials. Heat sensitivity and flammability are further disadvantages of these stones for house and furniture construction.
  • slab-shaped shaped stones are also produced in an inorganic bond.
  • so-called "washed concrete slabs” are known.
  • these known shaped stones are raw in appearance and comparatively sensitive to breakage, in particular due to air pores. Therefore, such slabs have so far almost exclusively been shown to be suitable as “walkway slabs,” wherever a comparatively low demand is made on aesthetic demands.
  • the present invention has for its object to provide a plate-shaped molded block which is inexpensive, fire-resistant and UV-resistant and aesthetically high quality, and a method for its production.
  • a plate-shaped shaped block is produced by self-compacting a mixture of at least cement, minerals and water into one
  • the mixture is so thin that it can flow in the mold without additional pressure and compress itself.
  • gas bubbles contained in the poured mixture are removed from the poured liquid by shaking the mold, by negative pressure with which the mold is applied and / or by penetrating the poured liquid with the spikes of a spiked roller.
  • the degassing can be supported by a degassing agent as an additional component of the mixture.
  • the shape in the form of a flat container with a flat bottom is particularly preferred. It then has edges corresponding to the outer contour of the plate-shaped shaped block produced. For example, it is rectangular and, for example, made of a light metal frame with a coated light metal frame and a formwork board as the floor.
  • the liquid mixture is then poured into the mold which is open at the top, which can be favored by an additional liquefier as a component of the mixture.
  • the filling height of the mold is preferably less than 40 mm or even less than 20 mm, so that particularly thin-walled plates are produced. Due to the fact that they are made from the liquid mixture, they are non-breakable due to the low proportion of pores.
  • the method according to the invention permits the production of panels with an edge length of greater than 1 m ⁇ 1 m, even greater than 1.4 m ⁇ 2.8 m, with a wall thickness of up to approximately only 12 mm.
  • the low proportion of pores allows grinding and / or polishing of the plate surface to result in a very high-quality appearance of the plate-shaped artificial stone. This means that slabs that are hard to distinguish from natural stones can be produced in a size in which natural stones are hardly available. This is particularly advantageous for use in architecture as a facade material.
  • sand and / or additives can also be added to the liquid casting mixture in order to produce different appearances of the plate surface: sand and / or grit with more than 90% quartz content are preferred - preferably with a grain size of more than 0.3 mm. Quartzite, granite, basalt and / or other natural stones and / or glass and / or metal such as, for example, aluminum, copper and / or (stainless steel), for example as grain and / or chips, can also be additives. In particular with a polished surface of the shaped stone according to the invention, an image is formed which is shaped by these materials and their shapes.
  • the liquid mixture can also have color pigments, so that the molded block is completely colored. Particularly when using white cement, a strong luminosity and color effect is advantageously obtained even with a small amount of pigments.
  • Another advantage of the shaped blocks produced according to the invention is to fill joints between the shaped blocks on site with the same liquid mixture. After a suitable surface treatment of the joint, it can then adapt to the appearance of the grouted molded blocks.
  • L-shaped shaped stones laid in a corner can be connected to form a seamless worktop with a continuously polished surface, for example by mitred shaped stones that are cut to fit each other and placed in an L-shaped manner, the miter joint with liquid
  • the mixture is filled in and polished after hardening, just like the surface of the molded stones.
  • the cement portion of the mixture of high-performance mortar with Portland cement and fine binder is formed. This can have a grain size smaller than 0.5 mm and / or a water / cement value smaller than 0.35.
  • shaped stones can be produced whose gas pores have a diameter of less than 1 mm or even less than 0.1 mm.
  • the gas pore volume fraction can be less than 0.1% or even less than 0.01%.
  • Figures 1 to 8 show schematic sectional views of the steps of an embodiment of the manufacturing method of a plate-shaped shaped block according to the invention.
  • Figure 1 shows a liquid mixture 2 of cement, minerals and water, which falls from a funnel 4 solely by its own weight and by opening one Slider 6 is poured into a mold 8.
  • the shape 8 is a flat container with a flat bottom 10 and a frame-shaped edge contour 12 which is rectangular in plan view (not shown).
  • the floor 10 is made of a formwork board - a board made of wood-based material, which is coated for easier demolding - and the frame 12 made of aluminum sheet coated with Teflon on the inside for easier demolding is screwed onto the top of the formwork board 10.
  • the frame 12 tapers in the direction of the base 10 for better demolding of the plate 14 which later hardened according to FIG. 4.
  • Mixture 2 flows self-compacting into mold 8 and is distributed evenly there.
  • the funnel 4 can be moved in a horizontal plane parallel to the bottom 10 of the mold 8.
  • there is a large-volume silo which is filled with the mixture 2 and from which a tubular connecting piece leads out on the underside.
  • the hose connector can then advantageously be moved in the horizontal plane parallel above the bottom 10 of the mold 8 for pouring the mixture 2 into the mold 8.
  • edge lengths of the cross section of the shaped slab shown are not shown proportionally.
  • an extreme relationship between the filling height of the mold 8 - that is to say the thickness of the plate (preferably smaller than shown) - and the edge dimension of the plate (preferably larger than shown) is preferred.
  • An edge dimension of approximately 1.9 m ⁇ 3.8 m with a filling height between 12 mm and 40 mm in the step according to FIG. 1 is particularly preferred.
  • This degassing is additionally supported by shaking the table 20 on which the mold 8 is supported.
  • a spike roller 22 can be used to drive through the liquid mixture 2 in the mold 8 according to FIG. 2b, which is a particularly simple method for supporting the degassing.
  • the free upper side of the mold 8 is covered in order to prevent rapid drying and / or premature hardening on the free upper side of the blank 14.
  • a second mixture (not shown) can be poured into the mold to the first mixture, with a different color and to control how much the two mixtures flow into one another after the first mixture and has set / or with an organic binding component of the second mixture.
  • the surface of the mass poured into the mold can also be covered in direct contact with a structured cover, so that the structure, for example in the form of a hewn stone surface, is reproduced on the later hardened form. In this case, the surface covered in this way is not machined further in accordance with FIGS. 6 and / or 8.
  • the plate 14 hardened in the mold 8 can be seen in FIG.
  • a layer 24 with excessive concentration of binder has formed under the free upper surface and, as a boundary layer with the bottom 10 of the mold 8, a layer 26, the consistency of which is influenced, for example, by release agent applied to the mold surface.
  • the same layer consistency 26 is also found in the edge area of the frame 12 of the shape 8.
  • FIG. 5 shows the blank 14 of the slab molded from the shape 8. After the hardening according to FIG. 4, it was lifted out of the mold 8, for example by means of vacuum suction devices (not shown) which gripped the top side of the blank 14.
  • the respective layers 24, 26 are removed by grinding, milling and / or sawing using suitable tools 28 according to FIG.
  • the edges of the blank 14 that have been in contact with the frame 12 of the mold 8 are then trimmed using suitable tools (not shown).
  • the molded block 14 is now allowed to harden further, which can be carried out in an air-conditioned atmosphere.
  • at least the surface of the shaped stone 14, which is provided as the visible upper side, is preferably polished with grit 800 using suitable tools 30.
  • the plate of the mentioned edge dimensions can now have a thickness of only 10 mm.
