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 interchangeable forms in molding machines, so-called stone makers. They consist of an upper mold part with stamps and a lower mold part which consists of a mold chamber block and side parts, the stamps fitting into chambers formed in the mold chamber block.
- the lower part of the mold lies on a forming table, so that the chambers for filling and subsequent compression are closed at the bottom.
- the compaction is carried out by vibrations which are transferred from a vibrator to the concrete body via the molding chamber block.
- the molded bodies formed are removed from the mold by lifting the lower part of the mold with the position of the stamp unchanged.
- the side parts serve to hold and guide the mold chamber block and as rails for the filling car.
- Molded lower parts are known from the prior art, which consist of a mold chamber block and laterally screwed side parts.
- the molding chamber block has an inner area with molding chambers and an edge area that has partial recesses.
- a disadvantage of such mold lower parts is that they can only be hardened to a limited extent, since large tensions build up in the mold chamber block. Furthermore are for the screwing of the side parts with the molding chamber block elaborate manufacturing steps such as drilling and tapping required.
- the invention has for its object to develop a mold for the production of concrete bodies, which is suitable for hardening and can be manufactured efficiently.
- the invention is also based on the object of developing a mold for producing improved concrete bodies, in which the shape of the manufacturing process in particular is positively influenced. Both tasks aim to increase the lifespan of the mold and to improve the quality of the concrete bodies produced with the mold.
- the mold according to the invention for producing concrete bodies has a lower mold part with a mold chamber block with a thickness or height which is essentially constant over the length and the width of the mold chamber block, the edge regions of the mold chamber block having recesses through which intermediate webs with approximately constant web width are formed, and the recesses or the intermediate webs serve for fastening side parts, the recesses in plan view being at least partially formed as an undercut groove with a lateral opening to the edge region and the side parts being screwed transversely to the course of the undercut groove.
- an edge-open structure is formed which counteracts the build-up of tensions or prevents the build-up of ring-shaped tensions through the lateral openings.
- such a construction of the mold chamber block allows the fastening of side parts by means of standard components, such as screws and slot nuts, without drilling or drilling on the mold chamber block
- Tapping work is required.
- the alignment of the screw connection of the side parts transversely to the course of the groove allows a high load on the side parts, since these are pressed on large contact surfaces by the screw connection onto the edge area of the molding chamber block.
- Undercut grooves are grooves that have a width on the groove base that is greater than the width of the groove opening, so that the groove, seen in cross-section, extends in a wedge, staircase or arc shape to the groove opening.
- a screw connection and / or bracing of the side parts via the groove with the molding chamber block and, if appropriate, additional welding of the side part and molding chamber block results in a particularly high-strength connection.
- the recess in particular in the form of a T-slot or L-slot, with a cavity which is angular and / or rounded in cross section and with a neck which opens towards the surroundings, the cavity and the neck preferably being designed as free burning.
- This makes it possible to use the cutting firing process for the formation of the mold chambers in the inner region of the Mold chamber block is used also for the formation of the edge area of the mold chamber block. This means that the inner area and the edge area of the mold chamber block can be processed on one machine using the same method.
- An advantageous embodiment of the subject matter of the invention provides for the grooves or the recesses to be arranged at regular intervals from one another in the edge region of the mold chamber block. This creates webs of the same width between the recesses. These ensure that the entire edge area shows a uniform behavior with regard to the hardening process.
- the use of T-shaped or L-shaped grooves in cross section is provided.
- At least one of the recesses in the edge region of the mold has a damping Fill filler.
- a damping Fill filler This saves the time-consuming welding of a cover protecting the recess against the penetration of concrete, and in particular also avoids heat distortion that occurs during welding.
- a filled recess acts on the mold during operation of the vibrator and after the vibrator has been switched off, so that in particular the vibrations of the mold subside quickly after the vibrator has been switched off and thus the formation of horizontal cracks on the side surfaces of the concrete bodies, which the shape is largely avoided.
- the side surfaces of the concrete body are thus technically and optically improved by the damping.
- Polymer concrete essentially consists of a plastic mass in which, for example, gravel and / or sand is embedded. This material is well suited to the stresses that occur on the mold, since it is particularly resistant to chemical and mechanical stresses.
- the opening cross section of the recess irregular or different from a simple geometric shape.
- By narrowing and / or widening in the cross section of the recess it is possible to transmit tensile loads to the filling material in addition to the compressive loads that can be absorbed through each opening.
- tensile stresses can be transmitted in the longitudinal direction of the dogbone.
- the filling material has an additional effect in such a configuration by absorbing and damping tensile loads in at least one direction, without requiring additional installation space for this.
- This leads in particular to a stronger damping of Bending vibrations since then almost the entire filler material has a damping effect, regardless of the direction of bending, since tensile and compressive loads occur simultaneously with each bend.
- the walls of the recess are connected to at least two anchor points by at least one anchor.
- Such an interconnection of walls makes it possible to keep the shape stable even in the case of a large number of recesses and / or in the case of large-volume recesses and to specifically concentrate or conduct loads and vibrations by means of the anchors.
- the invention advantageously provides for the recess in the molding chamber block to be oriented in any spatial direction. This makes it possible to act on all vibrations or bending, tensile, compressive and torsional loads present in the molding chamber block or to influence specific vibration directions or loads in a targeted manner.
- the invention provides for at least two recesses to be connected by at least one connecting space and in particular to design this as a bore.
- connection space with filling material. This enables an optimal interaction of the filled recesses. It is also provided to arrange the recess in a corner region of the molding chamber block in order to prevent vibrations from converging here.
- the invention provides for an insert made of filler material to be inserted or glued into the recess. This makes it possible to manufacture the insert efficiently
