Definitions

  • the invention relates to a reinforcement arrangement for a building material body and a method for producing the building material body using the reinforcement arrangement.
  • Building material bodies are, among other things, also manufactured in several layers or layers or in sandwich construction.
  • Such a building material body has a building material layer which has a load-bearing function. Concrete or mortar, for example, can be used as building material.
  • An intermediate layer, in particular for insulation, is applied to this building material layer.
  • This intermediate layer is then covered by a further outer layer, which is referred to as the facing layer.
  • the facing layer As a rule, the intermediate layer can absorb little or no forces. Therefore, anchors are introduced into the load-bearing building material layer, which protrude through the intermediate layer and connect the load-bearing building material layer with the outer layer or facing.
  • the production of such a sandwich building material body is complex.
  • connecting anchors When the building material layer is poured, connecting anchors usually have to be placed and aligned manually in the formwork, to which the outer layer or facing layer can later be attached.
  • sandwich panel anchor systems are offered, for example, by Philipp GmbH (www.philipp-ä.de).
  • FR 2 203 312 A5 shows a reinforcement arrangement with a reinforcement body, which is formed from intersecting reinforcement elements. Hinge elements can be arranged on the reinforcement body which hold a reinforcing rod or rod section which is rotatable about its longitudinal axis and which forms a foot section of a retaining anchor unit.
  • the retaining anchor unit also includes further reinforcing bars or rod sections which protrude obliquely or at right angles away from the foot section and represent a retaining section of the retaining anchor unit.
  • the holding sections of the holding anchor unit can be pivoted manually between a storage position and a working position. Similar reinforcement arrangements are also made U.S. 3,559,355 A and WO 2015/097377 A1 known.
  • the reinforcement arrangement has a shear connector which protrudes from the concrete slab when a first concrete slab is poured and extends through an insulating layer. The accessible end can be poured into another concrete slab.
  • GB 2539709 A describes a device for connecting reinforcement cages.
  • GB 2539709 A discloses the features of the preamble of claim 1.
  • Each reinforcement cage consists of reinforcement elements.
  • the device for connecting has a bracket which delimits an interior space together with a reinforcement element of a reinforcement cage. This interior space can be opened or closed on one side by means of a pivoted lever.
  • the pivotably mounted lever is also mounted on the reinforcement element to which the bracket is attached. It is biased into a position in which it rests against the bracket and closes the interior.
  • a component of a further reinforcement cage can protrude, whereby a connection between the reinforcement cages can be established.
  • the reinforcement arrangement according to the invention has intersecting reinforcement elements which are connected to one another and form a reinforcement body.
  • the reinforcement body is set up to reinforce a building material layer of a building material body to be produced and in particular to absorb tensile forces in the direction of extension of the reinforcement elements.
  • the reinforcement body can be designed as a reinforcement grid that extends essentially parallel to a plane.
  • the reinforcement body is designed as a textile reinforcement and comprises fiber bundles, the fibers of a fiber bundle being connected by a matrix.
  • the matrix can consist of a plastic material or a mineral material.
  • the reinforcement body is preferably free of metallic components.
  • a retaining anchor unit is arranged on the reinforcement body.
  • the holding anchor unit has a foot section and a holding section which is preferably integrally connected to the foot section.
  • the retaining anchor unit is attached to the reinforcement body by means of the foot section.
  • the fastening between the foot section and the reinforcement body can be non-positive and / or positive and suitable fastening means can be used, for example cable ties, fastening clips or the like.
  • the holding section can be moved between a functional position and a storage position.
  • the holding section is either mounted movably together with the foot section on the reinforcement body and / or the holding section is movably mounted on the foot section.
  • the holding section In the storage position, the holding section extends along the reinforcement body.
  • This is to be understood as a position of the holding section in which the holding section either rests against the reinforcement body or is arranged parallel to it at a small distance or extends at an angle of a maximum of 5, a maximum of 10 or a maximum of 20 degrees to the reinforcement body.
  • the holding section In the storage position, the holding section is thus arranged very close to the reinforcement body and has a maximum distance of at most 2 to 3 cm or a maximum of 5 cm from the reinforcement section at each point.
  • the holding section can be moved into the functional position, for example, by means of a pivoting movement.
  • the holding section protrudes transversely (obliquely or at right angles) away from the reinforcing body, an angle between the holding section and the reinforcing body preferably being at least 30 degrees up to 90 degrees.
  • the holding section assumes the position in which it can be cast into a load-bearing building material layer when a building material body is being produced.
  • the reinforcement arrangement thus already has at least one retaining anchor unit. Before or after arranging the reinforcement arrangement in a formwork, only the at least one holding section has to be moved into the functional position. Moving into the functional position can be done manually or automatically or automatically.
  • the holding section of the at least one holding anchor unit is urged in the direction of the functional position by means of a pretensioning force and / or a pretensioning torque in order to enable an automatic movement into the functional position.
  • the position and / or orientation of the holding section in the functional position can be structurally predetermined, for example by a mechanical stop and / or the pre-tensioning force and / or the pre-tensioning torque.
  • the reinforcement arrangement can be prefabricated. On the construction site or in a factory for the production of the building material body, there is no need for complex attachment and alignment of individual anchors on the reinforcement body after the reinforcement body has been arranged in the formwork.
  • the retaining anchor units are preferably arranged at a predetermined grid size or spacing from one another on the reinforcement body, which is based on a standard size of bodies or plates that are used as an intermediate layer in the manufacture of a sandwich building material body, so that the retaining sections each at joints between two bodies or plates of the Intermediate layer protrude through and can establish a connection between an inner, load-bearing building material layer and an outer layer or facing.
  • Each reinforcement element has at least one fiber bundle which is embedded in a matrix.
  • the reinforcement element is thus designed as a textile reinforcement element.
  • the reinforcement element is preferably free of metallic components.
  • the at least one retaining anchor unit has a pretensioning force and / or a pretensioning torque applied to it.
  • the pretensioning force and / or the pretensioning moment is directed in such a way that the holding section is urged in the direction of the functional position.
  • the functional position can be assumed automatically if the holding section is not held in its storage position by external forces acting on it.
  • the pretensioning force can be generated, for example, by a separate pretensioning means and / or by the foot section and / or the holding section itself.
  • a torsional force can be generated in the area of the foot section when the holding section is in its storage position, the torsional force forming the pretensioning force and urging the holding section in the direction of the functional position.
  • Each retaining anchor unit has two retaining anchors and in particular exactly two retaining anchors.
  • Each retaining anchor has a foot part and a holding part extending at right angles or at an angle to the foot part.
  • a kink and / or a bend can be formed between the foot part and the holding part.
  • the foot part and the holding part preferably enclose a kink or bending angle in the range from 70 degrees to 120 degrees, and more preferably an approximately right angle.
  • Each retaining anchor is arranged directly or indirectly on the reinforcement body by means of its foot part.
  • the foot parts of the two retaining anchors can therefore form the retaining section of the retaining anchor unit.
  • the holding parts of the holding anchors can form the holding section of the holding anchor unit. It is particularly advantageous if each retaining anchor is formed integrally without a seam or joint.
  • Each retaining anchor has at least one fiber bundle which is embedded in a matrix made of a plastic or a mineral material.
  • the retaining anchors can therefore have the same structure as the reinforcement elements.
  • Each retaining anchor is preferably free from metallic components.
  • each retaining anchor unit is preferably free of metallic components.
  • the holding part of each holding anchor is pivotable about a pivot axis.
  • the pivot axis is in particular also defined at least by the direction in which the foot part of the same retaining anchor extends.

  • an angle between the foot parts of the retaining anchors of the same retaining anchor unit is less than 180 degrees. In one embodiment, this angle can be at least 90 degrees.
  • the relative alignment and / or the relative distance between the holding parts can change when the holding parts are moved from the functional position into the storage position.
  • This change in the relative alignment and / or the relative distance can be used to generate or change a pretensioning force and / or a pretensioning torque which urges the holding parts of the holding anchors into the functional position.
  • a pretensioning means can be connected to the holding parts.
  • the pretensioning means is elastically deformable and / or effects an elastic deformation of the holding parts when they are in the storage position.
  • the prestressing force generated by the prestressing means can change as a function of the elastic deformation of the prestressing means, so that a change in the relative distance can be used to generate the prestressing force.

  • the at least one retaining anchor unit 17 is set up to automatically move into the functional position W when the reinforcement body 16 assumes the position that it should have in the building material body 21 to be produced.
  • the reinforcement body 16 designed as a reinforcement grid can be rolled up for storage, as shown schematically in FIG Figure 2 is shown. Due to the elastic deformation of the reinforcement element 18, the holding parts 41 or the holding section 33 are held in the storage position A. If the reinforcement grid is rolled up flat ( Figures 3 and 4 ), the holding section 33 moves or the two holding parts 41 move automatically into the functional position W.
  • a pretensioning force F and / or a pretensioning torque M acts on the holding section 33 or the holding parts 41, which urges the holding parts 41 or the holding section 33 in the direction of the functional position W.
  • each retaining anchor unit 17 has a pretensioning means 55.
  • the pretensioning means 55 is formed by at least one elastic band which is guided around the two holding parts 41 and is preferably arranged adjacent to the free end 34 of the holding section 33.
  • the band instead of the band, another elastically deformable body can also be used.
  • the pretensioning means 55 generates a pretensioning force F between the holding part 41, which urges the holding part 41 in the direction of the respective other holding part 41 of the same holding anchor unit 17 ( Figure 1 ). Because the two foot parts 40 enclose an angle ⁇ smaller than 180 degrees, the free ends of the holding parts 41 are at a greater distance from one another in the storage position A than in the functional position W. The pretensioning force F with which the two holding parts 41 are pushed towards one another is greater because of the greater elastic deformation of the pretensioning means 55 in the storage position A than in the functional position W. For this reason, the two holding parts 41 of the retaining anchors 38, 39 tend to move into the functional position W and a pretensioning moment M arises about the respective pivot axis S1, S2.
  • the prestressing force F or the prestressing moment M moves the holding section 33 of each holding anchor unit 17 into the functional position W.
  • external forces for example by rolling up the reinforcement body 16 for storage (cf. Figure 2 )
  • a movement from the storage position A into the functional position W can be blocked due to an elastic deformation of the retaining anchor unit 17 or the two retaining anchors 38, 39.
  • This also applies, for example, when several reinforcement arrangements 15 are stacked on top of one another, so that the weight of a reinforcement arrangement 15 lying thereon prevents the holding anchor units 17 of the reinforcement arrangement 15 underneath from moving their holding sections 33 out of the storage position A into the functional position W.
  • a second embodiment of a retaining anchor unit 17 is illustrated.
  • the retaining anchor unit 17 has two retaining anchors 38, 39, each with a retaining part 41 and a foot part 40.
  • the foot parts 40 protrude according to the exemplary embodiment Figure 7 approximately opposite to each other and thus enclose an angle ⁇ of approximately 180 degrees within the common plane.
  • an elastically deformable, twistable sleeve 57 is used as the prestressing means 55, which connects the foot part 40 of each retaining anchor 38, 39 to a bearing recess in a bearing body 59.
  • the bearing body 59 is part of the foot section 32 and can be connected to the reinforcing body 16 via one or more fastening means 42.
  • the sleeve 57 In the functional position W, the sleeve 57 is not twisted and the holding part 41 extends away from the bearing body 59, starting from the relevant foot part 40, in an orientation that it should assume in the functional position W, for example obliquely or at right angles from the reinforcement body 16 to the free end 34 down.
  • the holding part 41 is pivoted from the functional position W by approximately 90 degrees about the respective pivot axis S1, S2, the relevant sleeve 57 is twisted and generates a pretensioning torque M about the relevant pivot axis S1 or S2.
  • the holding part 41 of the relevant holding armature 38 or 39 is urged by the torsional moment M in the direction of the functional position W and assumes the functional position W without the action of an external force.
  • this version there is also the possibility of pivoting the holding parts 41 about the relevant pivot axes S1 and S2 in both directions, so that in this embodiment two storage positions A can be achieved, so to speak.
  • the bearing body 59 can be omitted in a further modification and the sleeve 57 can be fastened directly to the reinforcement body 16 by means of a fastening means 42.
  • Each holding anchor unit 17 can have a spacer 63 which, in the functional position W, extends obliquely or at right angles away from the foot section 32, preferably in a direction opposite to the holding section 33.
  • a spacer 63 which, in the functional position W, extends obliquely or at right angles away from the foot section 32, preferably in a direction opposite to the holding section 33.
  • an extension can be formed which extends approximately in the opposite direction to the holding part 41 and forms the spacer 63.
  • the spacer 63 is therefore also pivoted during the movement of the holding part 41 between the storage position A and the functional position W and thus rests essentially flat on the reinforcement body 16 in the storage position A, analogous to the holding part 41.
  • the spacer 63 protrudes transversely to the reinforcement body 16 and can be used to arrange the reinforcement arrangement 15 in the formwork 56.
  • the reinforcement arrangement 15 can be positioned in a formwork 56 by means of at least three such spacers 63.
  • a building material body 21 can be produced as follows:
  • the reinforcement arrangement 15 is arranged in the formwork 56 in such a way that the reinforcement body 16 assumes the position which it is later to have in the building material body 21. As a result, the holding sections 33 of the holding anchor units 17 are automatically moved into their functional position W.
  • the reinforcement arrangement 15 can be supported on the formwork 56 via spacers 63 or, as an alternative, separate spacers can be arranged between the reinforcement arrangement 15 and the formwork 56.
  • the reinforcement arrangement 15 can also be positioned in the interior of the formwork 56 using other positioning means and can do without spacers 63 which are supported on the formwork 56 on the inside.
  • a hardenable building material B is filled.
  • the filling takes place in such a way that the building material B forms the first building material layer 23, which covers the reinforcement body 16 and the foot sections 32 of the retaining anchor units 17. At least one section of each holding section 33 of each holding anchor unit 17 adjoining the free end 34 protrudes from the building material B.
  • an intermediate layer is arranged on the first building material layer 23, for example by arranging several bodies 25, which are designed, for example, as insulating bodies. At the joints between two adjacent insulating bodies 25 protrude the holding sections 33 of the holding anchor units 17 pass through and protrude beyond the intermediate layer 24.
  • second building material layer 27 can then be applied to this intermediate layer 24 and cured.
  • the second building material layer 27 forms an outer layer 26 of the building material body 21, which can also be referred to as a facing.
  • the second building material layer 27 is connected to the first building material layer 23, which represents a load-bearing layer 22, via the retaining anchor units 17 and in particular the retaining sections 33. Loads and forces acting on the second building material layer 27 can therefore be absorbed by the load-bearing layer 22 via the retaining anchor units 17.
  • the positioning of the retaining anchor units 17 on the reinforcement body 16 can take place in such a way that the distance between two retaining sections 33 corresponds to a predetermined grid, so that the bodies 25 can be arranged between them without having to cut holes or recesses in the body 25.
  • the bodies 25 are generally elastically and / or plastically deformable in such a way that the holding sections 33 can be passed through without problems at the joint or connection point of two adjacent bodies 25, as shown schematically in FIG Figure 10 is illustrated. It should be noted at this point that the representation in Figure 10 is not to scale and is for illustrative purposes only.
  • the diameter or the cross-sections of the holding sections 33 or holding parts 41 is usually sufficiently small that two adjacent bodies 25 adjacent to the holding section 33 directly abut one another or can be connected to one another by an adhesive layer.
  • the invention relates to a reinforcement arrangement 15 and a method for producing a building material body 21 using the reinforcement arrangement 15.
  • the reinforcement arrangement 15 has a reinforcement body 16 and at least one retaining anchor unit 17.
  • Each retaining anchor unit 17 is arranged or fastened to the reinforcement body 16 by means of a foot section 32.
  • a holding section 33 adjoining the foot section 32 can be moved between a storage position A and a functional position W.
  • the holding section 33 extends immediately adjacent along the reinforcement body 16 and can bear against the reinforcement body 16 at one or more points.
  • the functional position W the distance between a free end 34 of the holding section 33 opposite the foot section 32 is greater than in the storage position A.
  • the holding section 33 can be moved manually or automatically from the storage position A into the functional position W.
  • the entire reinforcement arrangement 15 is preferably free of metallic components.
  • the reinforcement body 16 and / or the holding section 33 and / or the foot section 32 are preferably designed as textile-reinforced elements.
