Definitions
- the invention relates to a method and a device for the production of moldings, in particular shaped concrete blocks from two different layers of material, which in at least one mold cavity of a vertically movable mold be filled in, the mold cavity approximately vertical Side walls, one by a vertically movable pressure plate closable top and a bottom part.
- Concrete blocks manufactured using such a method are used for example as paving stones, which essentially consists of a relatively inexpensive core concrete consist and the top with a layer of high-quality facing concrete is covered.
- the production this paving stones takes place in a known manner on a Molding machine with a vertically movable, top and bottom open form, which is placed on a vibrating table.
- After filling the core concrete into the mold nests of the The pressure plates assigned to the shape nests become the shape lowered until they rest on the core concrete.
- the core concrete is pre-compacted by shaking the form.
- the printing plates are raised again and the facing concrete in the resulting from the pre-compaction Free space of the mold nest up to the top edge of the mold filled.
- the printing plates again lowered and the two layers of material by renewed Shake the mold fully compressed.
- the resulting free space determines the height of the upper material layer or the thickness of the facing concrete. This height depends on the height of the first layer of material and is about 10% of the total height of the finished Paving stone. With low stones is therefore Facing concrete layer relatively thin, so with a mechanical Machining the stone surface, for example with the so-called faltering, the core concrete is revealed is coming. On the other hand, with paving stones with a large total height the facing concrete layer too strong, so that increased manufacturing costs arise. Another Disadvantage is that the production of concrete blocks with different heights in one shape is possible. There is a special shape for each stone height required.
- the invention has for its object the manufacturing process in the production of concrete moldings with several To improve material layers and different heights and rationalize, thereby reducing manufacturing costs to lower.
- the advantages achieved with the invention are in particular in that both different heights of the concrete body as well as different heights of each Material layers can be set in the same form can. This makes it for example in the production of Paving stones possible, the facing concrete layer on the Top of the paving stone in any desired thickness to attach. So there is only one shape left for Manufacture of concrete moldings with different Overall height and different layers of material required. With appropriate program controls the individual steps of the inventive Manufacturing process predetermined and according to the desired dimensions of the concrete body and the material layers can be set so that a fully automatic Manufacturing process without retooling is guaranteed.
- the molding machine 1 has a vertically movable mold 2 several mold nests 3 on, by vertical side walls 4 are limited.
- the mold nests 3 open at the bottom are bottom parts 5 assigned that can be moved vertically from below can be inserted sealingly into the respective mold cavity 3 can.
- the open top of the mold cavity 3 is known Assigned a pressure plate 6 each, the on the underside of a vertically movable ballast 7 are arranged.
- the bottom parts 5 are in recesses 8 of a scraper plate 9 guided vertically movable.
- the scraper plate 9 forms the top of a box 10 which with its open underside on a vibrating table 11 of the molding machine 1 rests.
- the Box 10 also form the vibrating table yourself.
- a horizontal support 12 is mounted so that it can move vertically, on the top of which the bottom parts 5 are attached.
- For the vertical drive of the carrier 12 is from the side led out of the box 10 and each with a drive unit 13, for example with the piston rod ends of Hydraulic cylinders, which are attached to the box 10, connected.
- the molding machine 1 has a frame 14 with side supports 15 which extend laterally beyond the vibrating table 11.
- the box 10 is in guideways 16 the carrier 15 mounted horizontally. This can the box 10 is moved horizontally out of the area of the mold 2 and at the end of its horizontal movement, also in a known manner, for example by a Inclined slot control 17, raised so far that a form board 18 for the removal of the finished concrete blocks can be pushed onto the vibrating table 11.
- two laterally arranged hydraulic cylinder 19 is provided for the horizontal drive of the box 10 .
- the carrier 12 is first with the floor parts 5 according to the desired stone height in moved up a first vertical position. there dip the bottom parts 5 into the mold nests 3 from below and seal the side walls 4 downwards. Then one first material layer 20, e.g. consists of core concrete, filled in the mold nests 3. The load 7 is lowered until the printing plates 6 on the material layer 20th lie on. Thereafter, the carrier 12 with the bottom parts 5 together with the first material layer 20 and the printing plates 6 down into a second vertical position according to Fig. 2 driven. The amount by which this corresponds Bottom part 5 and the first material layer 20 down were driven, the desired height of the second layer of material 21 after pre-compressing the first Material layer 20 is filled into the mold cavity 3. By Subsequent shaking of Form 2 becomes the first layer of material 20 pre-compressed.
- first material layer 20 e.g. consists of core concrete
- the pressure plates 6 with the Load 7 is moved upwards out of mold nests 3 again.
- the thickness of the second material layer 21 the distance from the top of the first layer of material 20 corresponds to the upper edge of form 2, can by appropriate selection of the entry depth of the floor parts 5 be determined in the form 2.
- the base parts 5 can also only be opened after pre-compacting the first material layer 20, which in according to this case already in the first vertical position Fig. 1 takes place up or down in the second Vertical position. In this position, the 3 corresponds to the second material layer 21 filled in the mold cavity 3. That way it is possible, the bottom parts 5 not only down, but also to drive upwards, since it is already pre-compacted a space has been created in the mold nest. This freedom is reduced if the bottom parts 5 for example be driven up so that the height of the second Material layer 21, which is then in the free space is filled, can be reduced.
- the printing plates 6 lowered again until they on the rest second material layer 21.
- the material layers 20 and 21 are relative to Form 2 moves down until the top of the bottom pieces 5 slightly below the lower edge of the form 2 or the material layer 20 lies (Fig. 4).
- adhering concrete residues are through the scraper plate 9 stripped. Then the layers of material 20 and 21 fully compacted by shaking Form 2.
- the box 10 After compacting, the box 10 is actuated the hydraulic cylinder 19 on the supports 15 horizontally moved aside until it is out of shape 2 is (Figs. 5 and 6).
- the oblique slot control 17 was the box 10 when moving out of the form 2 in known raised so far that the form board 18th could be pushed onto the vibrating table left.
- the form 2 For subsequent demolding the form 2 is raised in a known manner and the finished concrete block through the pressure plates 6 held down and transported away with the form board 18.
- the invention is also based on an embodiment, not shown applicable, in which the box 10 itself the Vibration table forms.
- the box 10 in known manner initially by a relatively small amount Move horizontally by about 10 cm to get a clean Separation of the first material layer 20 from the bottom part 5 receive.
- the box 10 in a known manner, for example by means of an oblique slot control, lowered so far that the form board 18 between the box 10 and the bottom of the form 2 can be inserted.
- FIG. 7 shows the vertical position according to FIG Fig. 1, but with a lower height of the first Material layer 20.
- the bottom parts are 5 accordingly moved further into the mold cavities 3.
- any desired stone height can be set.
- the height of the second is the same Material layer 21 variable by the immersion depth of the Bottom parts 5 in the form 2 after the pre-compaction of the Material layer 20 is changed.
- the according to the desired height of the concrete blocks coordinated movements of the floor parts 5, the printing plates 6 and the form 2 can by appropriate Program controls of a microprocessor predetermined so that a fully automated manufacturing process is made possible.
