Definitions

  • the invention relates to a method and a device for producing concrete blocks with a wide variety of recesses on the underside of the stone, on the stone sides and to compensate for different volume ratios of the concrete filled in individual mold chambers.
  • REPLACEMENT SQUARE (RULE 26)
  • the invention has for its object to provide a method and an apparatus according to claims 1 to 16, which ensure a reliable, clean and complete manufacture of such recesses, even if the recesses have complicated contours; In addition, the greatest possible economy should be achieved.
  • a single-stage or multi-stage device is used instead of the conventional mold floor or board.
  • the cams to be pressed in are mechanically extended from the device and thus represent the counterpart of the stone side to be manufactured.
  • the underside of the stone can be designed as desired using bolts and the like. These parts remain extended during the manufacturing process, only then are they retracted flush and the device is pulled away (like conventional mold bases). While pulling away, the device can be brushed off and thus cleaned. Now the finished concrete block can be ejected from the mold onto boards and the production cycle is repeated.
  • the mold sits on this frame during manufacture, the top of which serves as a mold base and thus forms the underside of the stone
  • ERS ⁇ ZBL ⁇ T RULE 26 There are movably mounted cams or slides (2) which are operated mechanically (or electrically, pneumatically, hydraulically.) (hydraulic cylinder (3) ...) and make the impression on the underside of the stone. Depending on the depth of impression and the type of application, the cams can be gradually shifted or operated in several stages and thus controlled, thus ensuring a clear impression of the cams in the stone.
  • the cams are retracted, the top of the device is flat again, and the device can thus be pulled away Fig. 2 or lowered Fig. 3.
  • the stone is placed on a board (7) and removed from the machine.
  • Fig. Shows a spring-loaded (or pneumatic) device, which is flat at the top in the unloaded state and represents the mold bottom, only when loaded, i.e. put on the mold frame (6), (Fig. 5), the plate (4) lowers and releases the cams (2), which now form the impressions in the stone. When the mold is lifted, the plate (4) goes by means of springs or pneumatic Elements (5) back to their starting position.
  • REPLACEMENT BLA ⁇ (RULE 26) Chambers are filled more or less, so that a different filling takes place. This different filling is not taken into account in practice, which means that the product manufactured, in our case the concrete block, can vary in height depending on the filling level of the respective chamber - inevitably associated with a different density of the respective blocks.
  • this filling difference is compensated for.
  • a single-stage or multi-stage device is used instead of the conventional mold floor or board, in which the surfaces to be pressed in (slides, strips ...) are mechanically moved out of the device during or after the pre-compaction.
  • the pre-compaction has taken place by lowering the load on the form and thereby compressing the concrete by means of pressure plates mounted on the load, the load remains in the position reached.
  • the concrete in the individual chambers is now compacted, but in different thicknesses for each chamber.
  • the surface elements mentioned are mechanically moved out of the mold base with an adjustable pressure and these surface elements exert pressure from below onto the amount of concrete delimited by the pressure plates from above.
  • the purpose of this is to evenly compact the amount of concrete poured into the individual chambers of the mold, which can be different for each chamber - so that the surface elements submerge to different degrees depending on the density achieved. Then these surface elements are locked, i.e. fixed in their position, so that they do not penetrate further into the pre-compacted concrete when the load is subsequently lifted (and thus the pressure is removed from above). This is followed by a so-called refilling of fine concrete (facing concrete) to the already pre-compacted amount of concrete. There is a further compression by lowering the load on the mold, but the locked surface elements remain unchanged. This means that only the refilled amount of concrete (facing concrete), which only makes up a fraction of the volume of the already filled and compacted concrete, has to be compacted. Only after the second compaction process has ended are the expressed surface elements retracted flush, the mold base is pulled away and the finished concrete block can be ejected from the mold onto boards.
  • these stones have more or less deep impressions on their underside, which prove to be practical and useful both in conventional use and when used as a drainage stone.
  • REPLACEMENT BLA ⁇ (RULE 26) The invention is explained in more detail with reference to the drawings.
  • the frame (1) is shown, which has to hold all the parts.
  • the mold (6) sits on this frame during production, the top of which serves as the mold base and thus forms the underside of the stone.
  • this frame there are movably mounted surface elements (2) (cams, slides), which are actuated mechanically (electrically, pneumatically, hydraulically ...) and make an impression on the underside of the stone during concrete compaction, e.g. via hydraulic cyclinder (3).
  • the cams can be shifted gradually, i.e. shifted or actuated in several stages, and thus controlled.
  • the cams are retracted, the top of the device is flat again, and the device can thus be pulled away Fig. 2 or lowered Fig. 3.
  • the stone is placed on a board (7) and removed from the machine.
  • a single or multi-stage device is used instead of the conventional mold base or board.

  • the stone is placed on a board and removed from the machine. The following consideration is intended to deal with removable mold floors in or on which vibrators are arranged.
  • Vibrating energy is introduced into the mold frame by vibrators arranged on the concrete block making machine, which are located below the mold frame, below the mold base underneath and also below a board located in between. This results in multiple damping of the vibrating energy, which means that in order to produce a high-quality concrete block, a very high output and high vibrating time are required for the vibrators. This has a devastating effect on the service life - both of the mold frame and the concrete block making machine.
  • these vibrators are already arranged in the removable mold base, so that any damping of the vibrations is eliminated.
  • the vibrating energy and the vibrating time can be significantly reduced.
  • Fig. 11 shows the previous arrangement, namely mold frame (20), mold base (21), board (22) and vibrating plate (23) with vibrators (24).
  • FIG. 12 shows the new arrangement, namely the mold frame (20), mold base (25) and vibrators (26) arranged therein and the board (22) located underneath.
  • Fig. 13 and 14 show stones that can be produced economically by means of these mold floors.

Abstract

Le procédé et le dispositif décrits servent à produire des pierres en béton pourvues des dépressions les plus diverses à leur face inférieure et à leurs faces latérales et à égaliser les taux volumiques variables du béton qui remplit les cavités individuelles de moulage. L'invention se caractérise en ce qu'un plateau amovibble (1) de support du moule est équipé d'éléments mobiles (2). Le moule (6) est posé sur ce plateau de support. Les éléments mobiles (2) (cames...) sont déployés avant, pendant ou après l'étape de compactage. Le volume de béton qui remplit les cavités individuelles de moulage est en même temps égalisé. Les éléments mobiles (2) (cames...) restent déployés pendant le compactage de la pierre. Le façonnage du contour de la pierre est assuré directement ou indirectement par le plateau (1) de support du moule. Après le compactage, ces éléments (2) sont rentrés. Le plateau (1) de support du moule est tiré latéralement ou abaissé. La pierre est posée sur une planche. Des vibreurs sont situés dans ou sur le plateau de support du moule, ce qui permet de transmettre directement l'énergie des vibrations au cadre de moulage.
