Definitions

  • the invention relates to a device for producing large blocks in the preamble of claim 1 specified genus on a stationary manufacturing plant.
  • Such a device is known to include a form in which concrete or another suitable material is compressed into blocks.
  • the compression takes place with the help a ram that presses the concrete into the mold.
  • the compression effect is through a shaking motion that acts on the shape during compaction increases.
  • the blocks made in this way have two abutting surfaces, which are built in brick Border condition horizontally with other blocks, over two visible surfaces as well over two storage areas, which connect to the adjacent blocks in vertical and thus transfer the weight of the blocks above.
  • the height of the blocks is the distance between the two bearing surfaces Are defined.
  • the shape in which the blocks are made has a cuboid shape and is laterally delimited by four walls.
  • the bottom of this form is a base board, on which the form is supported. For filling and receiving the press ram the shape is open upwards.
  • the object of the invention is therefore a device for producing large blocks of the type mentioned, with the help of the tolerance range of the height can be reduced.
  • the special arrangement of the profiling means that the block is "lying" in the form based on its later position in the masonry. It follows that the height measurement is no longer due to the fluctuating distance between the underlay board and ram, but by the rigid distance between the two opposite non-profiled mold walls is determined. This arrangement enables advantageously a reduction in the tolerance range to ⁇ 1 mm.
  • the two mold walls pivotable into the open position or movable away in the longitudinal direction of the shape are.
  • the two mold walls formed with the profile at right angles to Direction of the up and down movement of the ram and in one by the respective Form wall defined level are movable.
  • This movement carried out several times, causes advantageously that when filling the concrete also the areas of Can achieve shape that is directly below the perpendicular to the filling direction Profileing are located and thus shaded by the filling concrete. Form can therefore be filled completely while avoiding voids.
  • Another The advantage of this configuration is that the concrete can be mixed better near the respective mold wall during compression, which is the strength of the finished product in its peripheral areas. Multiple round trips Moving the respective profiled mold wall can ultimately lead to liability prevent the concrete on the mold wall and thus improves the molding of the Blocks.
  • the two with the profiling Form walls not to pivot about one or the other axis, but perpendicular to the direction for the up and down movement of the ram from the non-profiled Form walls move away, this movement parallel to the long one Edges of the exemplary embodiments shown in the figures take place.
  • the movable mold walls provided with the profiling are formed in this way be that only a part of them, as mentioned above, perpendicular to the direction of movement the ram is moved away while e.g. an upper part this is provided with the profiled mold walls stationary, and thus ensuring the shape stability of the shape if the remaining part of this profiled Walls is moved to the open position.
  • the shape shown in Fig. 1 as used in the manufacture of large blocks finds, consists of two opposing mold walls 1, which are not are profiled, and from the two remaining mold walls 2, with a Profiling 3 are provided.
  • the mold walls 1 and 2 thus form the side Limitation of shape.
  • the mold is open at the bottom and at the top. In this direction is the shape during the compaction of the support board, not shown and the press ram, also not shown, is limited.
  • the direction of movement of the ram described with arrow A is perpendicular for profiling 3 of the mold walls 2.
  • the device shown in Fig. 1 allows the special alignment of the profile 3 a "lying" production of the blocks.
  • "Lying” in this context means that the butt and bearing surfaces of the blocks are vertical during manufacture are arranged.
  • the two bearing surfaces are the non-profiled mold walls 1 assigned.
  • To create the tongue and groove system in the joint surfaces these are assigned to the profiled mold walls 2, the profiling 3 but in contrast to the usual arrangement is rotated by 90 °.
  • the one shown in Fig. 1 Embodiment thus allows the rigid distance between the two non-profiled Form walls 1 for defining the height with low tolerance is being used.
  • the blocks are tilted 90 ° to move them from their "lying” into one to bring "standing” position. Then the two storage areas are horizontal and the tongue and groove system in a vertical position, so its function in the Alignment of the blocks can meet.
  • a piston rod on the one hand causes that when filling the concrete in the Profiling 3 is moved, which also shaded by the profiling 3 Areas are filled and on the other hand there is an improved mixing in close to the profiled mold walls 2 instead of what the strength of the finished blocks benefits in this area.
  • This movement can occur both during compaction as well as during precompaction, the form being filled in a shaking motion is carried out.
  • Fig. 2 shows an apparatus for producing large blocks during molding of the final compressed large blocks.
  • the arrow C indicates the direction in which the shape is lifted to release the finished large block for removal.
  • the Opening angle can be chosen so that the profiled at the front end Form walls 2 gives a gap of about 5 cm. Cleaning the profiled mold walls 2 after molding with compressed air helps sticking to prevent the concrete on the profiled mold walls 2, so that the following Batch can be easily removed from the mold during molding.
  • the shape can also have a different shape, starting from the desired shape of the large blocks.
  • a pediment or other Fit possible.
  • the arrangement of the axis of rotation about each the profiled mold walls 2 are pivotable, only as an example and can be on others appropriate place.
  • Fig. 3 are the axes of rotation around which the profiled mold walls 2 each are pivoted, so arranged in the plane of the lower mold surface in the drawing at right angles to the course of the swivel axes in that shown in Fig. 2 Embodiment. 3 so the walls not like doors pivoted about an axis that is vertical in the drawing, but how Fold down in an axis that is horizontal in the drawing.
  • the pivot axis is parallel to Direction of lifting the shape (arrow C), whereas in the embodiment according to Fig. 3 shows the pivot axes in a plane parallel to the arrow shown in Fig. 1 B (direction of movement of the profiled mold walls).
  • the one with the help of the embodiment 3 achievable advantage lies primarily in the fact that this embodiment locking or unlocking easier.
  • the in Fig. 1st and 2 shown profiles only show their basic arrangement and not their exact design.
  • the profiles are moved 3 provided movable mold walls 2 perpendicular to the direction of movement the ram (arrow A), but also perpendicular to the direction in which the Mold is raised to release the finished large block for removal (arrow C).
  • the movable walls 2 in the longitudinal direction Form moved to its open position.
  • Fig. 5 shows a preferred embodiment in which the mold walls movable away 2 cannot be moved away from the other walls in their entirety. How 5 shows, only a section 2.1 can be moved away from the other walls, while a smaller section 2.2 is firmly connected to the other mold walls remains to ensure the stability of the shape.
