[Technical field]

[0001] The present invention relates to a method for manufacturing a building component, a system for manufacturing a building component and a building component. Summary of the Invention [Problem to be solved by the invention]

[0002] It is an object of the present invention to provide a method for manufacturing a building component, a system for manufacturing a building component and a building component, each of which has, in particular, improved properties. [Means for solving the problem]

[0003] The present invention solves these problems by providing a method having the features of claim 1, a system having the features of claim 9 and a building component having the features of claim 16. Preferred refinements and / or embodiments of the invention are set out in the dependent claims.

[0004] The method according to the invention, particularly automatic, is designed or configured or provided for producing a building component, particularly three-dimensional, which has at least one, particularly continuous, first area and a particularly continuous second area, particularly directly or directly continuous or adjacent to the first area, particularly after production, in which a construction structure or mounting structure of the building material is concealed, particularly after production. The method comprises the following steps: step a) is a particularly automatic discharge or ejection of building material to produce the first area and a particularly automatic / local supply of marking or detection material to the building material before, simultaneously and / or after the ejection, particularly before or simultaneously or after the ejection, and step b) is a particularly automatic discharge or ejection of building material, particularly before, simultaneously and / or after the step a), particularly before or simultaneously or after the ejection, in order to produce another area.

[0005] In particular the construction component may be a building construction component and / or a wall and / or a ceiling.

[0006] The first region can be referred to as a first zone and / or the second region can be referred to as a second zone. Additionally or alternatively, the second region can be distinguished from the first region. In particular, in the second region, the service structure of the building material cannot or need not be concealed. Additionally or alternatively, the first region and the second region can be or are particularly arranged differently, in particular at different positions or locations, in particular along or parallel to the nearest surface of the building material and / or building component.

[0007] The facility structure can be different from the building material. Additionally or alternatively, the building material can be concrete, in particular ready mixed concrete, and / or can be thixotropic. Additionally or alternatively, the building material can have a maximum grain size of at least 4 millimeters (mm), in particular at least 10 mm, in particular at least 16 mm.

[0008] Hidden can also refer to covered and / or can mean that the service structure is arranged behind the building material, in particular horizontally, and / or below the building material, in particular vertically. In particular, the service structure can be surrounded by the building material. The service structure is therefore not particularly easily visible on at least one side of the building component.

[0009] Particularly preferably, the first region can be one region and the second region can be the other region, alternatively, the first region can be the other region and the second region can be one region.

[0010] Building materials for making other areas may not be capable of or may not need to be provided with marking materials.

[0011] The marking material can be differentiated from the building material, in particular the concrete accelerator and / or the installation structure, in particular before application. Additionally or alternatively, step a) can comprise the introduction of the marking material into the building material. Additionally or alternatively, the marking material can be formed to change, in particular locally, a property, in particular physical, of the building material, in particular compared to without the marking material.

[0012] This allows, in particular, the marking material to locate or detect, in particular relatively accurately, areas / facility structures that would not be recognized and / or perceptible without the marking material. This can therefore make it possible to avoid, in particular unintended, damage to the facility structures, in particular when manufacturing the building component, in particular the first area, in particular when introducing fasteners and cable ducts. Additionally or alternatively, this can make it possible to shorten in time, or in particular completely avoid, conventional locating of the first area / facility structures, for example with a building plan that is generally relatively inaccurately documented and / or generally relatively inaccurately embodied. The method therefore has improved properties.

[0013] In a refinement of the invention, the marking material is arranged, especially in the first region, especially in a direction perpendicular to the surface, especially at least spatially closer to the surface, especially at least of the construction material and / or building component, than the installation structure. This can make it possible to sense the marking material in time, especially before damage to the installation structure, when processing the building component, especially the first region. In particular, the marking material can be arranged, especially partially, on the surface. This can make it possible to sense, especially the first region, especially the marking material, from the outside.

[0014] In particular the marking material can be designed to change or produce a change in the structure of the surface of the building material and / or building component, in particular locally, and is in particular a concrete retarder.

[0015] In a refinement of the invention, the marking material is a ferromagnetic substance and / or a pigment, in particular a pigment.

In particular the ferromagnetic substance can comprise metal flakes or be itself. Additionally or alternatively, the pigment can be different from the natural, color of the building material, for example gray or white, in particular compared to without the marking material, for example blue, purple, yellow, green or red. Furthermore additionally or alternatively, the building material can be colored, in particular in the first area or locally, by the marking material, for example a pigment. Additionally or alternatively, in particular within the first region, the building material can be or is provided with pigments such that the building material and / or the building component, in particular its surface, has a color gradation, in particular in a direction perpendicular to the facility structure and / or in a radial direction, in particular along or parallel to the surface, in particular with increasing intensity.

[0016] This makes it possible to indicate the spacing to the facility structure. Additionally or alternatively, the pigment may have a mass proportion of at least 0.2 percent (%), in particular at least 2% and / or at most 20%, in particular 10%, of the building material weight, in particular of the cement weight.

[0017] In the present embodiment, the equipment structure comprises a certain amount of different equipment types or equipment varieties. Different colorants are associated with the different equipment types. This makes it possible to clearly indicate or identify the equipment types.

In particular, the ejected strand can be continuous or can extend, in particular to a predefined length. Additionally or alternatively, the strand, in particular the width of the strand, can have, in particular, an overall wall thickness and / or ceiling thickness. Furthermore additionally or alternatively, the strand, in particular the cross section of the strand, can be ejected with interruptions. This can in particular form a shaft or an installation structure. Additionally or alternatively, strands can be placed or applied, in particular in layers, on top of strands that have already been printed or released, and / or other strands can be placed or applied, in particular in layers, on top of one or more strands. Additionally or alternatively, the building material can be solidified or shape-stable, in particular upon release. Additionally or alternatively, the three-dimensional printing method can provide the building material, in particular as already mentioned, with a marking material, in particular as already mentioned.

[0023] In a refinement of the invention, step a) comprises mixing, in particular injecting, the marking material, in particular already present, into the building material before ejection, in particular automatically, and ejecting the building material with the mixed, in particular injected, marking material. This allows for a relatively good mixing, in particular coloring, of the building material with the marking material, in particular the pigment. Injection can be performed at a pressure in particular higher than 1 MPa (10 bar), in particular higher than 10 MPa (100 bar). This, in particular the high pressure, can allow for a wide distribution of the marking material, so that no further mixing mechanism is required.
