Definitions
- the invention relates to a mold for concrete block molding machines with a mold frame which has at least one chamber open at the top and bottom, which is delimited by chamber walls.
- Such a form is known from EP-A2 0 318 708.
- the mold is placed on a vibrating table and filled with a relatively dry concrete mixture. Then a plunger that fits exactly into the chamber dips into the chamber, the load of which can also be provided with a vibrator. After compaction, the moldings, which remain in the chamber even after the vibrating table has been removed, are placed on a means of transport or on moldings produced in a subsequent operation after sprinkling dry sand as a release agent (multi-layer paver). For this purpose, the molding frame is raised, so that the punch, which initially remains in its position, presses the molding out of the chamber.
- a layer element is introduced into the empty chamber, which is to be permanently connected to the concrete body to be manufactured to form a composite body.
- the connection is achieved through a rough or specially adhesive * surface of the layer element on the side facing the concrete and / or through the use of suitable adhesives.
- layer elements which, in the application, lie on the top or on the visible side of the composite body are ceramic or clay elements, natural stone slabs or the like.
- the invention is based on the object of designing a mold so that even heavy moldings can be held in the mold and lifted with it, and that the mold automatically insert and hold insert parts and layer elements before filling the concrete and also after the molding process, the insert part can lift and carry together with the concrete body or the composite body in order to be able to place it on a different base than the production base (vibrating table).
- the proposed clamping device increases the lateral force exerted on the part to be held and thereby increases the friction on the chamber wall within a certain time interval r that is selectable.
- r time interval
- the clamping device can contain flat wedge slides which can be moved by means of a working cylinder and which in turn are operatively connected to a suitably designed clamping member. The return of the clamping members to the starting position could be carried out with the help of springs or also hydraulically / pneumatically.
- the chamber walls have a groove on the inside into which an elastic hose is inserted, which is acted upon by the pressure medium.
- the groove preferably extends horizontally, ie parallel to the lower edge of the chamber wall. If the hose is pressurized, it inflates and tends to swell over the groove. He presses on the part to be held.
- a clamping device can extend from chamber corner to chamber corner or can also be shorter than the chamber wall in question. If the part to be held is relatively light, a clamping device on a chamber wall may already be sufficient. Clamping arrangements can also be made on two opposite or be attached to all chamber walls.
- the hose or several hose sections is or are part of a closed ring line which extends over the entire chamber circumference and whose connecting line arriving from a pressure control device is fed through a chamber wall. It is possible to use angle pipes at the corners and a metal pipe T-piece for the connecting line and to connect these pipes with straight, flexible hose sections.
- fully vulcanized ring hose can also be used. This has the advantage that the ring hose, in addition to its clamping action, also fulfills a sealing function and prevents the penetration of concrete sludge into the gap between the chamber wall and the part to be held.
- the hose and groove cross section In order to promote the retraction of the hose in the depressurized state, it is expedient if the groove is narrowed towards the groove openings by bead-like projections of the groove side walls.
- the groove side walls can also be intentionally kept flat so that the hose, which is also provided with flat flanks, can slide between them.
- the hose In order to achieve a high contact strength, the hose can have a flat pressure surface between the flanks. However, this can also be provided with sealing lips or grooves.
- the hose be held on the back, ie inside the groove, so that it is completely in the groove due to its elasticity or due to the application of negative pressure withdraws.
- This fixing of the hose in the groove can also be effected by a corresponding design of the cross section, for example in that a bead is formed on the back of the hose, which snaps into a correspondingly designed receiving groove.
- a bar covering the hose is inserted into the groove as a clamping member.
- This can be made of a suitable plastic or metal and can be connected to the hose with the aid of flat clips which partially enclose the hose or in some other way.
- a wider expansion element i.e. H. a cushion or bellows acted upon by the pressure medium may be provided, such an expansion element being able to actuate a plate-like clamping member.
- the chamber wall has, in addition to resetting the inner surface above the clamping device, a horizontally extending groove, into which an elastic impact protection strip is inserted, which is softer than the chamber wall, but is still harder than the inflated clamping hose.
- the impact protection strip which can have a rectangular or trapezoidal cross section, is preferably arranged directly under the shoulder, which forms the transition between the inner surface and the recessed inner surface section of the chamber wall.

- FIG. 2 shows, in a corresponding representation, a shape for a light well with a frame-shaped lower sleeve with an angular cross section
- FIG. 3 in a corresponding representation, a form for a concrete channel with a lower sleeve
- FIG. 4 in a corresponding representation, a form for a gutter in the form of a composite body made of a gutter made of clay and a concrete lower body,
- FIG. 5 shows a vertical section of the lower part of a chamber wall and a composite panel of approximately natural size produced in this chamber
- Figure 10 is a multi-sectional top view of a
- Ring hose as used in the molding chamber of Figure 5, on a smaller scale and
- FIG. 11 shows a vertical section of the lower part of another chamber wall, the hose not being shown for clarification.
- FIGS. 1 to 4 Examples of applications of the invention are to be given with the schematic representations of FIGS. 1 to 4.
- Figure 1 a box shape with two opposite longitudinal walls 1 and 2 is shown, which is used to produce a curb 3 made of concrete. To simplify the diagram, the rear end wall is not shown.
- This is shown in Figure 10.
- This is a frame-shaped hose with a connector, which is made in one piece. If this hose, which wraps around the curb 3, is pressurized, it prevents the concrete body from falling out of the mold when it is lifted off the
- the shape according to FIG. 2 is used to produce a U-shaped light well 10 for basement windows.
- the cutting plane runs across the U-legs.
- the sectional view shows the two outer transverse walls 11 and 12 and the two inner ones Cross walls 11 'and 12', which form the legs of the light well 10.
- a U-shaped lower sleeve 13 is inserted into the shape. It has an L-shaped cross section, the vertical leg forming the recess. Opposite this vertical leg there are grooves in the chamber walls 11 'and 12' with inserted tubes 6 ', which could be connected by means of a groove and a piece of hose in the longitudinal wall connecting these two transverse walls.
- this mold is lowered over the base sleeve, which is brought in and precisely localized by means of a support pad.
- the hose 6 is then pressurized and the lower sleeve is thus clamped in the mold. Now the support underlay of the lower sleeve can be removed and the shape can be lowered onto the vibrating table. Even after the concrete has been poured in and compacted, the form with the concrete and the lower sleeve can in turn be placed on another conveying surface. The inner pressure of the hose 6 'is released for demolding.
- a molding box similar to that of FIG. 1 with longitudinal walls 1 and 2 is provided.
- a concrete trough 14 is produced therein.
- a lower sleeve 15 is used, on the top of which the channel shape is designed as a positive counterpart.
- the shape first receives the sub-sleeve 15 and holds it in place by means of the pressurized hose. After the concrete has been poured in and compacted, the concrete and base sleeve are placed on any surface and shaped. After the concrete has set, the lower sleeve 15 is released from the finished concrete channel 14.
- the number of sub-sockets present in a manufacturing company usually corresponds to a daily production of corresponding molded concrete parts.
- an approximately the same shape as in the previous example is used to produce a water channel as a composite body made of a concrete lower part 16 and a channel part 17 made of clay.
- the gutter part 17 is taken up by the initially empty shape like the lower sleeve 15 according to FIG. 3.
- the main difference from this previous example is that the gutter part 17 binds firmly to the concrete body due to the stepped dovetail shape of its upper side.
- the composite body created in this way has a high stability as a result of its concrete lower part 16 and offers a channel made of the ceramic material desired here on the upper side in the installed state.
- FIG. 5 shows a scale representation of the part of a mold of interest for producing a composite panel, which consists of a natural stone panel 18 and a concrete layer 19.
- the natural stone slab 18 is naturally rough on its upper connection surface according to FIG. 5 and possibly provided with cutouts to increase the connection strength and additionally coated with an adhesive.
- Composite panels of this type are used to produce particularly attractive floor coverings that can be driven on by heavy vehicles.
- the molding chamber In the upper region of its chamber wall 20, in which the stamp runs and concrete is inserted, the molding chamber has a clear width which corresponds exactly to the width of the natural stone slab 18. Starting a little above the natural stone slab 18, the molding chamber widens over an inclined shoulder 21 and forms with the side surfaces of the natural stone slab 18 an approximately 2.5 mm wide gap 22.
- the recessed flat surface section 23 at the lower end of the chamber wall 20 goes into the sloping surface below 24 over which in the event of a non-exactly matching localization of the mold frame and the natural stone slab to prevent their damage when the mold frame is lowered and to effect a corresponding centering.
- the chamber wall 20 has an essentially rectangular groove 25, the upper side wall of which is approximately at the same height as the upper surface of the natural stone slab 18.
- the groove 25 is narrowed towards the opening, ie towards the natural stone slab 18, by two bead-like curved projections 26 on the groove side walls.
- the natural stone slab 18 has a chamfer 27 on its upper edges. The natural stone slab 18 is thus spaced on all sides from the chamber wall 20 so that it cannot be damaged when it is shaken.
- the all-round uniform width of the gap 22 is also important because the side surfaces of the load-bearing concrete layer 19 would have to form a common plane with the side surfaces of the natural stone slab 18.
- FIG. 7 shows another hose cross section which is intended for a groove with flat side walls and which accordingly has flat flanks 28 and a flat pressure surface 29. Wedge-shaped sealing lips 30 are formed on this in the manner of a suction cup.
- the tube profile according to FIG. 8 differs from the previous one by a smaller oval cavity and by an almost rectangular solid profile section, which can also be referred to as a molded gripping and sealing strip 31.
- the associated groove shape is also shown in FIG. What is essential here is a rear T-shaped profile projection 32, which engages in a corresponding shape of the groove base and thus holds the otherwise round tube in the groove, which widens towards the groove opening. If the hose is pressurized, it fills the groove and extends beyond it over a relatively large width, which is indicated by dash-dotted lines.
- FIG. 11 shows the formation of a further chamber wall 32 in the area of interest.
- the hose groove 33 shown here has a slightly different cross-sectional shape than that in FIG. 5. It is rounded at the bottom of the groove.
- a further rectangular groove is provided above the hose groove 33, into which a shock protection strip 34 made of rubber or a suitable plastic is inserted. This groove is located at the transition point between the upper section and the lower, recessed section of the inner wall surface.
- the natural stone slab 35 used here has no bevel on the transition edge between its surface and its side surface.
- the impact protection strip 34 serves to protect this edge when shaking and to additionally seal the gap designated 22 in FIG.
