description

The invention relates to a method of manufacturing with the end face and on two opposite side walls shaped stones provided with a profile, in particular hollow blocks for the construction of walls and the like by placing the individual ones one above the other in a form-fitting manner on the profile side Pormsteine as well as performing the procedure O

Methods and devices for the production of molded blocks with and without profiling of the side walls are known. For this purpose, a concrete mixture is poured into a mold in the usual way and compacted by shaking it in and pressing it into it Shaped stone stored outside the molding machine to dry. For the conventional construction of walls, etc., in which the individual shaped bricks are connected to one another by known binders and smaller, manufacturing-related irregularities are each worked up or worked out as _a result.

can be matched, the molded blocks manufactured in the manner described above generally meet the given requirements.
To meet the need for new technologies in the construction industry

kannj, shaped stones when building also without connecting and possibly level-compensating binder rail, through To use only one on top of the other, one behind the other, depends on the extraordinary precision with which such shaped stones must be produced ^ accordingly a completely new technique of its production «

The object of the invention is a method and a device for the production of shaped blocks of the type mentioned at the beginning, each individual shaped block with sharp edges in its size and shape congruently corresponds to the other, so that one of a large number of shaped bricks that are only placed on top of one another and one behind the other built wall even without correcting the course of the wall on a case-by-case basis additional aids such as intermediate layers or leveling intermediate pieces and the like. in all their areas runs in the required vertical and horizontal plane »

The object is achieved by the method according to the invention that a certain amount of a concrete mixture of a Filling carriage by means of a vortex located in it into a downwardly through a removable or detachable shaped sheet covered mold frame and filled with a vibrator Directed vibrations that are coordinated with the molded block and vibrated by a profile press die with counter-current vibration is pressed in, the mold being constructed in such a way that the vibration of the combination of table vibration, Punch vibration and the hydraulic pressure

The device for carrying out the method is characterized in that that on the surface of the ram and axially underneath on the frame of the device, axially height-adjustable adjustable abutments are arranged,

Further features of the invention are Enhaad of the drawing, in which shows an embodiment of the invention is illustrated in more detail.

The shaped bricks to be produced point both on the two end faces and on the top and opposite underside a profiling so that when they are placed on top of each other they form a solid bond on four sides. To this Wise can be built with them by simply stacking them. It is also possible to change the design, shape and size to change the mold side by a respective molding device. It should also be pointed out that the manufacture shaped blocks automatically under the Shape. The removal can be done manually or by a fully automatic device, in the case of transport drying and packaging systems work together.
