DD244944A1 - METHOD FOR STRUCTURING CONCRETE SURFACES - Google Patents

Abstract

The invention serves the design of Sichtflaechen of concrete elements in construction by producing a structure. The structure is achieved by removing concrete parts with the aid of separating tools. These are guided in the x, y, z direction by hand or controlled. It is possible to achieve an ornamental structure with multi-layered and multi-colored concrete (sgraffito).

Description

embodiment

The invention will be explained in more detail with reference to an embodiment.

Fig. 1 shows a schematic representation of an operating in x, y, z axes machine 5, which worked out a desired surface structure 4 via a specially designed for the material concrete cutter 3 from the surface of a multi-layer concrete element 1 with colored layer 2. Here, the control can be done manually preferably by means of template or programmed according to the known methods in mechanical engineering.

According to the invention, it is also possible to move the concrete element in the x-, y-, z-axis with the machine stationary or to let the movements in the working directions x, y, ζ combine machine and concrete element.

The method is also suitable for structuring of building surfaces during reconstruction work or for the subsequent structuring of the surfaces or surface parts of newly erected buildings.

By using concrete elements with colored layer 2, the plasticity of the structure can be increased.

Due to the variability of the tools, working feed rate and speed, the method is suitable for all concrete elements, all other cement or gypsum-bound building materials including their partial or total substitution by silicate industrial waste materials and natural stones and brickwork for exterior and interior surfaces.

For this 1 page drawing Field of application of the invention The invention relates to a method for producing surface structures of concrete by means of mechanically acting cutting tools. The invention is particularly applicable to prefabricated concrete, reinforced concrete, aerated concrete and other concretes or concrete-like materials that are stationary or stationary produced in horizontal or vertical production and the surface to be machined is not covered by a molding or inaccessible. Characteristic of the known technical solutions The surfaces of precast concrete parts are designed by means of coating processes, insert elements, washouts (wash-gravel plaster) and, above all, prototypes in negative production. In addition, the artisanal steinmetzmäßige processing of precast and built-in surfaces is known. Is known in other fields of technology, for. B. in machine tools, workpiece surfaces, ζ. Β. to structure by milling and to program these tools programmed. In addition, gas concrete elements are subsequently calibrated by milling without achieving a structure. Object of the invention. The aim of the invention is the industrial production of a variety of surface structures in the prefabrication or the object for the variable design of views on and in buildings without extensive design and equipment and with rapid response to changes in demand and small numbers or unique or rare design variants including architectural design. Explanation of the essence of the invention The invention has for its object to make the visible surface / visible surfaces of buildings or building parts by producing a structure industrial. This is done according to the invention by the separation of parts (eg concrete parts) with the help of tools that are suitable for processing the surface materials (hard metal or diamantmaterialbestückte milling cutters) and are selected suitably in speed and working feed. The surface to be treated, which is to be structured, may in this case be completely cured or be in the setting stage. The tool / tools is / are performed relative to the workpiece in the directions x, y, ζ so on the surface to be machined that the spatially precisely determined dissolution of the corresponding structure provided unwanted concrete parts can be done. It is possible that, depending on the production conditions, the processing machine and / or the workpiece to be machined in the directions x, y, ζ moves. The movement can be controlled manually or with program controls (template, fixed or / and freely programmable control). The dissolution of material parts can be made of solidified or partially solidified material depending on the stability of the contours.
According to the invention, in multilevel / multi-colored concrete, an additional color design can be created (sgraffito).
