Definitions

  • the invention relates to a mold for the production of concrete bodies according to the preamble of claim 1.
  • Such forms are used as forms of change in molding machines, so-called stone pavers. They consist of a top mold with punches and a lower mold part, which consists of a mold chamber block and side parts, the stamp fit into chambers formed in the mold chamber block.
  • the lower mold part lies on a shaping table, so that the chambers are closed at the bottom for filling and subsequent compression.
  • the compression takes place by vibrations, which are transmitted by a vibrator on the molding chamber block on the concrete body.
  • the side panels serve to hold and guide the mold chamber block and as rails for the filling car.
  • Moldings are known from the prior art, which consist of a mold chamber block and laterally screwed with these side parts.
  • the molding chamber block has an inner region with molding chambers and an edge region which partially has recesses.
  • a disadvantage of such lower mold parts is that they can only be cured to a limited extent, since in the mold chamber block in this case build up large voltages.
  • a mold for the production of concrete bodies which has a lower mold part, which consists of a mold chamber block and with this screwed side parts, wherein the mold chamber block has an inner region with mold chambers and an edge region on which at least Partial recesses are provided, wherein the recesses in the edge region for attachment of the side parts in plan view are at least partially formed as an undercut groove with a lateral opening.
  • the invention has for its object to develop a mold for the production of concrete bodies, which is suitable for curing and is rationally manufacturable. Furthermore, the invention has for its object to develop a mold for the production of improved concrete body, in which in particular the manufacturing process is positively influenced by the mold. Both tasks are aimed at increasing the life of the mold and improving the quality of the concrete bodies produced by the mold.
  • the mold according to the invention for the production of concrete bodies has a mold bottom with a mold chamber block with a substantially constant over the length and the width of the mold chamber block thickness or height, wherein the edge regions of the mold chamber block have recesses are formed by the intermediate webs with approximately constant web width and the recesses or the intermediate webs are used for fastening side parts, wherein the recesses in plan view are at least partially formed as an undercut groove with lateral opening to the edge region and a screwing of the side parts takes place transversely to the course of the undercut groove.
  • This is formed in the edge region of the mold chamber block an open-edged structure, which counteracts the build-up of stresses or prevents the build-up of annular stresses through the lateral openings.
  • such a construction of the molding chamber block allows the fastening of side parts by standard components, such as screw and sliding block, without the need for drilling or tapping on the molding chamber block.
  • the orientation of the screwing of the side parts transversely to the course of the groove allows a high load on the side parts, as they are pressed at large contact surfaces of the screw on the edge region of the molding chamber block.
  • Undercut grooves are grooves, which have on the groove bottom a width which is greater than the width of the groove opening, so that the groove seen in cross-section wedge, stair or arcuate to the slot opening.

  • An advantageous embodiment of the subject invention provides to arrange the grooves or the recesses at regular intervals to each other in the edge region of the molding chamber block. As a result, webs of the same width are formed between the recesses. These cause the entire edge area with respect to the hardening process shows a uniform behavior.
  • the use of cross-sectionally T-shaped or L-shaped grooves is provided.

  • At least one of the recesses located in the edge region of the mold is provided with a damping element Fill filler.
  • Polymer concrete consists essentially of a plastic mass, in which, for example, gravel and / or sand is embedded. This material is well suited to the loads occurring on the mold, as it is particularly resistant to chemical and mechanical stress.
  • the opening cross-section of the recess irregular or deviating from a simple geometric shape.
  • tensile loads on the filling material.
  • the filling material unfolds in such a form by the absorption and damping of tensile loads in at least one direction an additional effect, without requiring additional space is required. This leads in particular to a stronger attenuation of Bending vibrations, since then regardless of the bending direction almost the entire filler acts damping, as with each bend simultaneously tensile and compressive loads occur.
  • the invention provides to connect walls of the recess by at least one anchor with at least two anchor points.
  • Such an interconnection of walls makes it possible to keep the shape stable even with a large number of recesses and / or in the case of large-volume recesses and to selectively concentrate or guide loads and vibrations by means of the armature.
  • the invention provides to orient the recess in the mold chamber block in any spatial direction. This makes it possible to act on all present in the mold chamber block vibrations or bending, tensile, compressive and torsional loads or to influence specific vibration directions or loads targeted.
