Definitions

  • the invention relates to methods according to the preamble of claim 1 or 2 and to a mold according to the preamble of claim 9.
  • forms which consist of a mold and wear frame enclosing a mold space on the circumference and of a plate-shaped mold closure element which closes the mold space at the bottom, which e.g. made of hard rubber or a rubber-elastic plastic material.
  • the mold frame is then fastened, for example, in an opening of a first machine element of a molding press and the mold closure element in a recess of a second element of the molding press.
  • a prefabricated concrete and the top of the plate forming fine concrete are then successively introduced into the closed mold, then forming a bottom of the plate coarse concrete and then compressed the header and the base by compression.
  • the mold for discharging this blank on the lower side is opened by moving away the mold element, and the blank is ejected downward.
  • side contour is to be understood as meaning a shape deviating from a plane surface of the peripheral sides of the base plates, preferably a curved or corrugated and, in particular, an irregularly curved or corrugated structure, but in the form that extends in any desired cross-sectional planes parallel to the top of the plate in each case the same circumferential course or the same peripheral structure results, d.
  • Elevations and depressions formed by the side contour are oriented with their longitudinal extent perpendicular to the plane of the top of the plate and have a constant cross section in this axial direction.
  • structured plate top is understood to mean a top surface which has a surface structuring formed by depressions and / or elevations or raised areas.
  • structured edge is to be understood as a broken or rounded edge which, in plan view of the plate, has, for example, a rectilinear or essentially rectilinear or an irregular and / or a single or multiple curved course, at least in a partial region.
  • the plates indicated generally at 1 in Figures 1 and 2 are made from a cementitious material, with an upper surface of the plate 1 forming header 2 made of a high quality concrete or fine concrete (facing concrete) and with a the underside of each plate. 1 forming core or base 3 of a coarser concrete (core concrete).
  • the in the illustrated embodiment substantially square plate 1 has on its peripheral sides a curved in plan view of the plate side contour 4 and is structured at its top at 5, ie provided with projections or depressions. Furthermore, the edge enclosing the top 6 is broken in the sectional plane perpendicular to the top, ie rounded and at the same time irregular, ie formed following the curved peripheral contour, so that for the plate 1, at least after laying a rustic or natural stone plate corresponding optical appearance results.
  • the forming of the plates 1 takes place, for example, on a conventional machine or molding press 7, which i.a. a rotatable about a vertical axis rotatable turntable 8, on which a plurality of molds 9 are provided distributed at equal angular intervals about the axis of rotation.
  • Each mold 9 consists in a known manner from a used in an opening of the turntable form and wear frame 9.1, which surrounds the actual mold space 10 at the periphery and the inner surface of the peripheral surface of the respective plate 1 forms, as well as a plate-shaped, the underside of the respective shape 9 or the mold space 10 at the bottom final form closure element or mold base 11, which is formed as Tiefbettmatrize and for example made of a rubber-elastic material, eg Hard rubber exists.
  • the mold base 11 is provided on a machine part 12, which is moved with the turntable 7, but can be lowered relative to the turntable 7 for removing the plate blank produced by press molding.
  • the production takes place in such a way that in a first working position into the respective closed mold 9, the intent or fine concrete, which also has a relatively high water content, and then in a further working position of the core 3 forming the base, are formed. Concrete are introduced, which also has a lower water content than the fine concrete. At least after the introduction of the core concrete is carried out using a mold or press die 9.2 a pressing of the concrete in the mold space 10 and then at a further working position, the dispensing or discharging and forwarding of the thus prepared Plate blanks after lowering the closure element 11 for storing the plate blank during setting or curing of the concrete.
  • the profiling or structuring 5 of the top plate and the rounded or broken edge 6 already in the production of the plate blank of the forming and wear frame 9.1 is on its inner surface over the entire frame height with one of the side contour 4 corresponding contour, which extends according to the invention over the entire height of the inner surface of the forming and wear frame, in such a way that the mold frame has on its inner surface in all perpendicular to the frame axis oriented planes each have the same cross-section.
  • the press die 9.2 of the mold 9 is adapted at its periphery to the inner cross section of the mold frame 10, d. H. also the stamp 9.2 has on its outer circumference the side contour 4 of the floor panels 1 to be produced corresponding contour.
  • the lower mold part 11 is provided as Tiefbettmatrize with a peripheral edge region 14 having trough-like depression 15.
  • the edge forms a flat surface 14.1, against the closed mold 9 9.1 of the mold frame 9.1 with its lower face fully rests and thereby ensures a tight closure of the mold 9 at the transition between the mold frame 9.1 and the mold base 11.
  • Adjoining the surface 14.1 to the mold space 10 towards a surface 14.2, which is down to the bottom 15.1 of the trough-like recess 15 and the shape of the edge 6 is correspondingly concave curved.
  • the surface 14.2 of the waviness of the edge is corrugated accordingly, ie it has a changing slope.
  • the transition between the surfaces 14.1 and 14.2 of the side contour 4 follows in the form that the surface 14.2 at this transition as seamless as possible or steplessly merges into the side surface 4 forming the inner surface of the mold frame 9.1.
  • the forming the side contour 4 of the inner surface of the forming and wear frame over the entire height of this frame is formed so that the transition between the surfaces 14.1 and 14.2 follows exactly in the course of the side contour 4, that the punch 9.2 is adapted on its peripheral surface to the inner cross section of the forming and wear frame 9.1 or the course of the lateral contour 4 forming inner surface of the forming and wear frame 9.1 so that on the one hand the bottom plates 1 are produced in the desired shape without disturbing transitions, on the other When removing a plate blank after molding no material remains in the mold frame and in the lower mold part remain.
  • the contour of the inner surface of the forming and wear frame forming the side contour 4 of the bottom plates 1 extends over the entire height of this frame, so that with the 9 adapted to the inner cross section of this frame ram the respective blank is completely ejected during demolding and this also no material residues in the form and wear frame 9.1. It is also essential that on the one hand by the facing concrete with a relatively high proportion of water, the top of the corresponding bottom plate 1 is optimally formed, but that absorbed by the subsequently introduced core concrete with a lower water content excess water from the facing concrete from the core concrete and so the adhesion of the first very wet facing concrete is prevented at the formed with the trough-shaped recess 15 lower mold part 11.
  • the depth of the trough-like depression 15 is significantly smaller than the thickness of the base plates produced.
  • the bottom 15.1 of the trough-like depression 15 is correspondingly provided with a complementary profiling or structuring 13.
  • FIG. 6 shows, in a representation similar to FIG. 3, as a further possible embodiment a mold 9a corresponding to the mold 9, in which instead of the deep bed mold or the mold bottom 11 a mold bottom 11a is used, which is flat or substantially planar at the top and at the bottom of a recess 15 corresponding recess 16 and there is also provided with a profiling 5 forming complementary profiling 17.
  • the lower mold part 11a is then deformed such that, due to the recess 16, the rounded or broken or irregularly running edge 6 adjoining the lateral contour 4 is formed, and the profiling 5 is formed by the profiling or projections 17.
  • An advantage of the mold 9a is that the mold bottom 11a again assumes its plane or flat state after opening the mold for discharging the plate blank at the top and thereby particularly effectively prevents unwanted adhesion of concrete residues on the die or on the mold base 11 a is.
  • the base plates 1 By structuring 13 formed by elevations and intervening recesses of the die 11 and 11a, the base plates 1 produced on its upper side also the structuring 5 formed by depressions and elevations.
  • the bottom plates 1 produced with the mold 9 or 9a are subjected to a further surface treatment according to FIG.
  • a first method step shown in FIG. 7 in the position a the plates 1 are brushed on their surface side provided with the structuring or profiling 5 by means of a rotating brush, which in the illustrated embodiment is cylindrical.
  • the bristles 18.1 of this brush 18 are each made at their free ends of a high-strength material or provided with such a material, for example with a diamond coating.
  • the plates 1 are moved on a feed dog 19 under the rotating brush 18.
  • the distance between the brush 18 and the feed dog 19 is adjusted so that the bottom plates 1 are primarily worked on the raised areas of their structured top or on the raised areas of the local profiling 5 by brushes, so at these raised areas a particularly smooth Surface results, which differs significantly from the surface structure in the trough-like depressions.
  • a special visual appearance is achieved for the plates 1, with greasy appearing smooth raised areas and slightly rougher recessed areas.
  • the plates 1 are provided on their upper side with a paint application, which is applied in a metered manner, for example via a spray nozzle 20.
  • the lacquer used is selected so that it cures in a subsequent process step (position c of Figure 7) after penetrating the surface of the respective plate by the UV light of a UV radiation source 21.
  • the application of varnish closes pores on the upper side of the plate, especially in the non-brushed, deeper areas of the surface structure, so that a surface seal is produced, which inter alia results in the accumulation of dirt and / or ingress of liquids into the respective plate and an associated disadvantageous optical element Appearance for the plate prevented. Further, by pre-brushing the panels and thereby reducing surface roughness in raised areas, the amount of paint needed is significantly reduced.
