Method for Producing Concrete Stones with a Modular Molding Structure

Abstract

The invention relates to a method for producing concrete stones during which a number of individually selectable separate molds can be placed on a base frame, and the base frame X is fitted with a number of selected separate molds A, B, C and D. The separate molds A, B, C and D are detachably joined to the base frame X in order to hold the separate molds A, B, C and D in place. The separate molds A, B, C and D are filled with liquid concrete material. Hardened concrete stones are removed from the separate molds A, B, C and D, after which the separate molds A, B, C and D are detached from the base frame X.

Description

The invention is explained in more detail on the basis of exemplary embodiments in the figures of the drawing, in which:

FIG. 1 shows a selection by way of example of four separate molds A, B, C and D,

FIG. 2 shows a representation by way of example of a base frame X,

FIG. 3 shows a complete mold formed in a modular manner and

FIG. 4 shows a schematic representation of the method for producing concrete blocks.

FIG. 1 shows four different separate molds A, B, C and D (in particular fillable frame elements with bases, the frame elements having, for example, a rectangular cross section). Such separate molds A, B, C and D may be kept in a storage area 3, in particular in an automated rack store. The separate molds A, B, C and D may in this case comprise frame elements comprising, for example, plastic or wooden frames. Altogether, the separate molds A, B, C and D serve for filling with concrete material, in particular liquid concrete material, to create concrete blocks corresponding to the size of the inner spaces 1 of the separate molds A, B, C and D.

FIG. 2 shows a base frame X to which separate molds A, B, C and D according to FIG. 1 can be attached. For this purpose, the base frame X may have separating locations 2 for opening. The separate molds A, B, C and D may have pins which can be pushed into openings of neighboring separate molds A, B, C and D or of the base frame X, as in a construction kit.

FIG. 3 shows such separate molds A, B, C and D according to FIG. 1 introduced into a base frame X according to FIG. 2. A complete mold of a modular form is obtained, it being possible for the base frame X to be fitted in a next production sequence with new separate molds E, F, G, H, I etc. (not depicted), which can be selected from an overall stock of separate molds.

FIG. 4 shows a computer user station 4 (for example a personal computer) for the selection 5 of specific separate molds A, B, C, D, E, F etc. from a storage area 3 for the fitting 6 into a base frame X. Once production has been performed, the separate molds are returned again, possibly after cleaning, to the storage area 3 (step 7).

Claims

1. A method for producing concrete blocks, it being possible for a number of individually selectable separate molds to be attached to a base frame, comprising the following method steps: fitting of the base frame with a number of selected separate molds,filling the separate molds with liquid concrete material,removing the cured concrete blocks from the separate molds,separating the separate molds from the base mold.

2. The method as claimed in claim 1, the base frame being formed as an outer frame.

3. The method as claimed in claim 2, a number of separate molds being detachably attached in the interior of the outer frame.

4. The method as claimed in claim 1, the separate molds being detachably connected to one another.

5. The method as claimed in claim 1, a range of different separate molds being kept in a storage area.

6. The method as claimed in claim 5, individually selectable separate molds being taken by means of an automatic removal device from the storage area to the base frame for fitting.

7. The method as claimed in claim 1, the separate molds being separated from the base frame and returned to the storage area after use.

8. A base frame for producing concrete blocks, in particular for producing concrete blocks by a method as claimed in claim 1, it being possible for the base frame to be detachably connected to separate molds for filling with liquid concrete material inner molds.

9. A separate mold for attaching to a base frame, as claimed in claim 8, the separate mold having connecting elements for the detachable connection to corresponding connecting elements of the base frame.

10. A modular mold system for producing concrete blocks, with a base frame, to which one or more individually selectable separate molds can be detachably attached for filling with liquid concrete material.
