Definitions

  • the invention relates to a method for creating reinforcement for a precast concrete component in a production environment and a system for creating reinforcement for a precast concrete component in a production environment.
  • precast concrete components by filling concrete into a formwork, with reinforcement being arranged in the formwork to reinforce the precast concrete component before it is filled with concrete.
  • a formwork is usually created from various formwork components and the reinforcement is positioned in the formwork by hand.
  • the object of the invention is to provide an improved method and an improved system in which, in particular, suitable reinforcement for a precast concrete component can be used.
  • the core idea of the present invention is to create reinforcement from individual components, the reinforcement not being available in stock as a three-dimensional object or flat object, but a desired reinforcement can be replicated using simple components. Any number of complicated reinforcements can be created from individual components. Reinforcement that meets the requirements and/or has sufficient strength can be used. A user should be given assistance on how to carry out the reinforcement by projecting the reinforcement in its three-dimensional form into the production environment
  • the invention provides a method for creating a reinforcement of a precast concrete component in a manufacturing environment.
  • the method uses a device to project the reinforcement into the manufacturing environment.
  • the method comprises the steps: a) reading in a target reinforcement for the precast concrete component, b) creating a component reinforcement plan, the at least one first individual component extending in at least one direction and a second component to be connected to the first component for constructing the target reinforcement, and connection points of the first component with the second component of the component reinforcement plan, and c) projecting the component reinforcement plan with display of the components and the connection points in the production environment by means of the device for projecting the reinforcement.
  • precast concrete component includes a prefabricated component with concrete for use on a construction site, which is designed in particular flat, so that in the prior art welded wire meshes are used for this purpose, which usually consist of two sets of wires crossing each other at right angles.
  • the precast concrete component can have reinforcement that extends out of the concrete and can be used to connect the precast concrete component to another element or component on the construction site.
  • the reinforcement guided out of the precast concrete component can be arranged in or on a reinforcement of another element and this area can be filled with concrete.
  • reinforcement includes a structure, also called reinforcement, which can usually be made of structural steel, reinforcing steel, reinforcing steel, glass fibers, carbon fibers, aramid and/or a combination of the materials mentioned.
  • the reinforcement can have individual elements or components that are connected to one another.
  • target reinforcement includes reinforcement that has been planned or constructed for the prefabricated concrete component to be produced.
  • the "target reinforcement” corresponds to the static requirements that are placed on the precast concrete component to be manufactured.
  • the target reinforcement specifies the area and the density of the reinforcement, as can usually be formed by means of mats and/or three-dimensional structures, for example.
  • the term “reading in the target reinforcement” includes an electronic conversion of the planned or constructed target reinforcement into data and/or signals that can be processed with a computer. Conversely, the data and/or signals reflect the design of the target reinforcement. For example, a target reinforcement can be read in such that the points in space in the precast concrete component at which there should be reinforcement are saved, specifying how strong or thick the reinforcement should be at the respective point in space.
  • production environment in the sense of the description includes the area of production for the precast concrete component.
  • the area may be within a factory floor, a precast concrete plant, or the like.
  • production environment can include the immediate area that is intended for the production of the precast concrete component, so that in particular the entire formwork and an edge area that adjoins the lateral formwork to the outside can be regarded as the production environment.
  • the term "device for projecting reinforcement into the manufacturing environment” encompasses a device that can optically project reinforcement into the manufacturing environment such that the individual components and the connection points between the components can be visualized by a user.
  • the device can have a projector-like unit that displays the image of the target reinforcement with the components and the connection points (component reinforcement plan).
  • the device for projecting the reinforcement into the production environment is physically in a housing, in particular a freely programmable, arithmetic unit (machine or electronic circuit), for example in the form of a (micro)processor, (micro)controller or similar.
  • the process of reading in the target reinforcement and calculating it in the reinforcement to be displayed with individual components and connection points can be carried out.
  • the device for projecting the reinforcement into the production environment receives signals or data from an arithmetic unit which is present outside of a housing of the device for projecting the reinforcement into the production environment and not to the device for projecting the reinforcement into the production environment belongs in itself.
  • Said arithmetic unit can be connected to the device for projecting the reinforcement into the production environment wirelessly or by cable.
  • the arithmetic unit can control the device for projecting the reinforcement into the production environment, so that the device for projecting the reinforcement into the production environment does not have its own control unit physically in a housing must have.
  • the device for projecting the reinforcement into the production environment can have a "device for detecting the production environment", which can have at least one sensor with which the production environment can be detected.
  • the device for projecting the reinforcement into the production environment can be connected wirelessly or by cable to the device for detecting the production environment in order to exchange data and/or signals, in particular bidirectionally.
  • the senor of the device for detecting the production environment can be any technical component with which the production environment can be detected.
  • the sensor can be a technical component with which the position of the casing or one or more casing elements in space can be determined in relation to the device for detecting the production environment.
  • the location/position/orientation of the formwork in space can be determined so that the device for projecting the reinforcement into the production environment can project the reinforcement exactly at the point where the reinforcement should also be arranged according to the plan.
  • the sensor of the device for projecting the reinforcement into the production environment can be an optical sensor, an acoustic sensor (sound sensor), a mechanical/tactile sensor and/or an inductive sensor. More than one sensor or more than one type of sensor can also be provided. If more than one sensor is provided, the sensors be of the same or different nature.
  • a sensor can preferably be a combination of the aforementioned configurations of the sensors, in which case a configuration with two or more types of sensors can be preferred. Different configurations of casing and/or casing element(s) can be detected by means of different sensors and/or a combination of sensor types in one sensor.
  • the sensor can in particular be an optical sensor. It is possible, for example, for the device for detecting the production environment to optically detect the formwork or one or more formwork elements. It may be that the sensor optically scans the production environment. The scanning can take place according to a pattern, for example in rows and/or columns, according to the principle of a transit time measurement. It can additionally or alternatively be provided that an optical scanning of the floor formwork element or the formwork environment takes place or supports this by projecting a pattern onto the formwork environment. A predetermined pattern can be projected into the manufacturing environment, where the projection of the pattern can be detected. The position of the formwork or one or more formwork elements in space can be determined from the deviations between the predetermined pattern and the projection. For example, a distance and the like can be determined from the deviation based on the position or inclination of the casing to the device for detecting the production environment.
  • a “component reinforcement plan” is understood to mean information corresponding to reinforcement constructed according to design reinforcement and containing the components and connection points connecting the components to "recreate” the design reinforcement.
  • the term “creating” a component reinforcement plan is understood to mean the transformation of a target reinforcement into a “component reinforcement plan”.
  • the "creating” can be done by means of an arithmetic unit which knows the components to be used, for example from a database accessible to the arithmetic unit.
  • Components of the component reinforcement plan can be of the same type or different components, which consist in particular of (reinforcing) steel.
  • components are used that are not factory-prefabricated planar reinforcement, but components that preferably extend essentially in only one direction.
  • rod-shaped components can be used.
  • the exclusive use of rod-shaped components is very particularly preferred, since a simple design can be achieved in this way, which also allows increased flexibility. If only rod-shaped components are used, all that is required is to store these components, by means of which essentially any type of target reinforcement can be “transformed” into a component reinforcement without large amounts of waste.
  • bar-shaped component in the sense of the description includes both a straight bar and (rebar) steel in rings, in which the (rebar) steel for the reinforcement is coiled up on rings.
  • the diameter of a bar-shaped component can range from 5mm to 50mm for the straight bars and from 5mm to 20mm for the steel in coils.
  • the length of the straight rods can generally be between 3m and 40m, in particular between 12m and 25m, very particularly preferably between 12m and 20m, more preferably between 12m and 15m.
  • connection is used as the connection at the connection points. This enables a simple configuration which also provides a high level of flexibility.
  • the connection is a robust and secure type of connection.
  • the manufacturing environment is the formwork, so that the reinforcement can be created in the formwork itself. This enables the reinforcement to be used directly in the formwork without an intermediate step of costly stockpiling of the reinforcement.
  • the components are supplied as needed.
  • components can be automatically supplied in such a way that a rod-shaped component is produced by cutting off a desired length from a reinforcing steel on site.
  • automation can take place in such a way that a device for feeding the components has a cutting device that can be controlled by an arithmetic unit that knows the target reinforcement plan in electronic form and/or has been informed of the individual components of the target reinforcement plan in order to enable the device to feed the components or to control the cutting device in order to automatically produce the components.
  • a device recognizes and logs the components and the connections made at the connection points.
  • the quality and quality of the manufactured precast concrete component can be logged, specifically for each individual precast concrete component.
  • the device for detecting the manufacturing environment as described above can be used as the device, wherein the device for detecting the manufacturing environment can be part of the device for projecting the reinforcement into the manufacturing environment , or can exist independently of this.
  • the invention also provides a system for creating reinforcement for a precast concrete component in a manufacturing environment with a formwork.
  • the system includes a device for projecting the reinforcement into the manufacturing environment.
  • the device for projecting the reinforcement into the production environment and/or a computer functionally connected to the device for projecting the reinforcement into the production environment is designed to read in a target reinforcement for the precast concrete component, to create a component reinforcement plan that contains at least a first individual , component extending in at least one direction and a second component to be connected to the first component to build up the target reinforcement and connection points of the first component to the second component of the component reinforcement plan, and the component reinforcement plan with display of the components and the Project connection points into the manufacturing environment.
  • FIG. 1 shows a production environment 1 for a precast concrete component to be produced, in which a formwork 2, only partially shown for the purpose of better illustration, is arranged.
  • a target reinforcement is provided for the precast concrete component to be produced, which was created according to static aspects.
  • the target reinforcement is read into an arithmetic unit of a device 3 for projecting the reinforcement into the production environment 1 .
  • the target reinforcement is converted by an arithmetic unit of the device 3 for projecting the reinforcement into the production environment 1 by a component reinforcement plan 4, the at least one first individual component 5 extending in at least one direction and a second with the first Component to be connected component 5 for building the target reinforcement, and connection points 6 of the first component 5 with the second component 5 of the component reinforcement plan 4 is created.
  • the component reinforcement plan is projected into the manufacturing environment 1 by means of the device 3 for projecting the reinforcement.
  • the projection is such that the individual components 5 and the connection points 6 are displayed in the production environment 1 in order to realistically simulate the virtual (projected) reinforcement.
