Abstract

A method for producing concrete components with at least one visible side by introducing concrete into at least one formwork or form, wherein the visible side of the concrete component is veneered with a plurality of facing elements and interposed visual joints for producing a dry stone wall structure.

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 term "substantially" or "approximately" or "approx." In the context of the invention means deviations from the exact value by +/- 10%, preferably by +/- 5% and / or deviations in the form of for Function insignificant 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.

The invention will be explained in more detail below with reference to the figures of exemplary embodiments.

Show it:

1 in a schematic representation and in side view of a concrete component in the form of an angular support element for supporting walls on slopes;

2 the top view of the visible side of a leg of the concrete component of the 1 ;

3 in a functional diagram, different process steps for producing concrete or concrete blocks from a concrete block block by columns;

4 a plan view of a fracture-gray surface generated during splitting.

In the figures is 1 a concrete component in the form of an angle support element, which is made in a suitable form by pouring concrete, with two legs 2 and 3 of which the thigh 2 on its outer side or visible side with a veneer 4 is provided. This consists of a variety of concrete in the thigh 2 embedded and brittle stone-like facing elements 4.1 with visual joints 5 so that the visible side of the thigh 2 after installing the concrete component 1 For example, when creating a slope support wall, the visual impression of a dry stone wall of the brittle gray visible surface forming facing elements 4.1 taught. The facing elements 4.1 be in the production of the concrete component 1 in a mold used for this purpose, in the 3 schematically with 10 is indicated, inserted or introduced and by subsequent introduction of the concrete of the concrete component 1 or thigh 2 involved in this concrete. Preferably, however, after the introduction of the veneering elements 4.1 and before placing the concrete of the concrete component 1 of the thigh 2 into the mold 10 grouting the between the facing elements 4.1 formed joints with a preferably cementitious grout from the back of the facing elements 4.1 ago. This not only the visual joints 5 In the desired shape and / or coloring obtained, 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 be contaminated with concrete.

The 3 shows process 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 becomes after the setting of his concrete along the lines 8th transverse or perpendicular to its longitudinal extension split several times, so that a concrete block 7 several cuboid concrete blocks 6 are obtained, in each case on two opposite, generated by the columns pages 6.1 have fracture-gray surfaces, as in the 4 is indicated. The while splitting the concrete block 7 accumulating residual or end pieces 9 , each only on one side 9.1 a fracture-gray surface created by splitting irregularly and purely by chance 9.1 have, are as facing elements 4.1 in the production of concrete components 1 used and with her broken side 9.1 in the for producing the respective concrete component 1 used formwork or form 10 inserted in such a way that the brittle side 9.1 the wall of the form 10 is adjacent and after the production of the concrete component 1 the visible surface of the veneer 4 forms.

The method described allows for the columns of the concrete block 7 accumulating tails 9 make sense to use.

It is understood that the cross section, the concrete block 7 perpendicular to its longitudinal extent, is smaller than the area of the end pieces 9 to be blinded visible surface of the thigh 2 so that this viewing surface of a variety of end pieces 9 with the intervening visual joints 5 is formed. For a visually appealing appearance for each veneer 4 with different in size and / or shape facing elements 4.1 to achieve, are preferred as facing elements 5 Tails 9 of concrete blocks 7 used with different cross section and / or when splitting the concrete block 7 accumulating tails 9 in turn, again by columns or otherwise in different facing elements 4.1 divided.

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. So it was assumed above that the tails 9 in the for producing the concrete component 1 used form 10 , Of course it is also possible, the facing elements 4.1 or tails 9 on a part or bottom of the mold 10 or on at least one subcarrier 11 to the delusion 4 to put together ( 3 ) and then the veneer prefabricated and, for example, with the grout grouted joints 5 in the formwork or form 10 contribute.
