Abstract

Method for producing concrete components (1) having at least one visible side (4) by introducing concrete into at least one formwork or mold (10), the visible side of the concrete component (1) being provided with a plurality of facing elements (4.1) and between facing visual joints (5) for producing a dry stone wall structure is blinded.

Description

The invention relates to a method according to the preamble of claim 1.

The object of the invention is the rational production of concrete components with visually appealing visible surfaces. To solve this problem, a method according to claim 1 is formed.

In the method according to the invention concrete remnants, which are obtained as end pieces in the production of concrete blocks, such as paving stones by columns of concrete blocks, used as facing elements for visual design of the visible side of concrete components, in particular concrete components in the form of concrete angle support elements , Angle supporting elements made of concrete or cement-bound material are concrete components, as used for example for the construction of retaining walls.

The essential aspect of the method according to the invention is thus to be seen in the fact that the visible side of the concrete element is veneered with a plurality of facing elements and intermediate visual joints for producing a drywall wall structure, that as veneers residual or end pieces are used in the production of Concrete blocks incurred by splitting a concrete block, and that the end pieces are introduced into the mold so that they form the visible side of the concrete component in the concrete of the concrete component with its generated by the splitting breaking side of the concrete component. In this way, it is particularly advantageous to produce precast concrete parts or above-mentioned concrete structural elements with visually appealing visible surfaces in a rational and cost-effective manner.

Particularly advantageous is an angle support element made with two legs as a concrete component, wherein the veneer is provided on the outer or visible surface of a leg.

Further advantageous after the introduction of the facing elements into the mold and before the introduction of the concrete into the mold grouting of the visual joints is performed.

In an advantageous embodiment variant, the veneer or parts of this veneer formed by the veneering elements are introduced in a form prefabricated on an auxiliary carrier into the mold used to produce the concrete component.

The term "essentially" or "approximately" or "approx." means for the purposes of the invention deviations from the respective exact value by +/- 10%, preferably by +/- 5% and / or deviations in the form of insignificant for the function changes.

Further developments, advantages and applications of the invention will become apparent from the following description of exemplary embodiments and from the figures. In this case, all described and / or illustrated features alone or in any combination are fundamentally the subject of the invention, regardless of their summary in the claims or their dependency. Also, the content of the claims is made an integral part of the description.

In the figures, 1 is a concrete component by way of example in the form of an angular support element, which is made in a suitable form by pouring concrete, with two legs 2 and 3, of which the leg 2 on its outer side or visible side with a Veneering 4 is provided. This consists of a variety of embedded in the concrete of the leg 2 and brittle stone-like facing elements 4.1 with sight joints 5, so that the visible side of the leg 2 after the obstruction of the concrete component 1, for example, when creating a slope retaining wall the visual impression of a stone wall from the a fractured gray visible Surface-forming facing elements 4.1 mediated. The facing elements 4.1 are in the production of the concrete component 1 in a mold used for this purpose, in the FIG. 3 schematically indicated with 10, inserted or introduced and incorporated by subsequent introduction of the concrete of the concrete component 1 or the leg 2 in this concrete. Preferably, however, after the introduction of the facing elements 4.1 and prior to the introduction of the concrete of the concrete component 1 of the leg 2 into the mold 10, the joints formed between the facing elements 4.1 have a preferably cementitious grout from the rear side of the facing elements 4.1. As a result, not only the visual joints 5 are obtained in the desired shape and / or color, but it is also avoided that against the wall of the mold 10 adjacent visible surfaces of the visible surfaces of the facing elements 4.1 are contaminated with concrete.

The FIG. 3 shows method steps of a method for producing concrete blocks 6, for example in the form of masonry or paving stones from a cuboid concrete block 7. This is split after setting its concrete along the lines 8 transverse or perpendicular to its longitudinal extent, so that from a concrete block. 7 a plurality of cuboid concrete blocks 6 are obtained, each having on two opposite, generated by the splitting sides 6.1 brittle surfaces, as shown in the FIG. 4 is indicated. The resulting in columns of the concrete block 7 residual or end pieces 9, each having only on one side 9.1 an irregular and purely randomly generated by fracture brauhy surface 9.1 are used as facing elements 4.1 in the manufacture of concrete components 1 and this with their bruchrau side 9.1 inserted into the formwork or mold 10 used for producing the respective concrete component 1 such that the bruchrauen side 9.1 of the wall of the mold 10 is adjacent and forms after forming the concrete component 1, the visible surface of the veneer 4.

The described method allows us to use the costs incurred in columns of the concrete block 7 tails 9 meaningful.

It is understood that the cross section, the concrete block 7 has perpendicular to its longitudinal extent, is smaller than the surface of the end pieces 9 to be veneered visible surface of the leg 2, so that this visible surface of a plurality of end pieces 9 with the interposed visual joints. 5 is formed. To have a visually appealing appearance for each veneer 4 in size and / or shape To achieve different facing elements 4.1, are preferably used as facing elements 5 end pieces 9 of concrete blocks 7 with different cross-section and / or divided when columns of the concrete block 7 end pieces 9 in turn again divided by columns or other ways in different facing elements 4.1.

The invention has been described above by means of an embodiment. It is understood that changes both modifications are possible without thereby departing from the inventive idea underlying the invention. It has been assumed above that the end pieces 9 in the mold used for the manufacture of the concrete component 1. Of course, it is also possible, the facing elements 4.1 or end pieces 9 on a part or bottom of the mold 10 or at least one auxiliary carrier 11th to put together the delusion 4 ( FIG. 3 ) and then prefabricated the veneer and, for example, also with the grout grouted visual joints 5 in the formwork or form 10 introduce.
