Patent number: 11536031Abstract: A reinforcing mesh element for embedding in a cement matrix of a building structure, preferably in a corner region or in a curved region. The reinforcing mesh element has a grid-shaped arrangement of fiber bundles that are embedded in a plastic matrix. The reinforcing mesh element has at least one rigid zone and at least one flexible zone. In the at least one flexible zone the plastic matrix consists of an elastomer plastic. The plastic matrix comprises in the at least one rigid zone a thermoset plastic. The flexible or rigid form of the reinforcing mesh element is thus obtained, due to the set-up of the plastic matrix. Additional stiffening bodies or stiffening elements that are connected with the grid-shaped arrangement can be omitted. The reinforcing mesh element can be adapted to the respective situation and simplifies handling when manufacturing a building structure.Type: GrantFiled: November 6, 2017Date of Patent: December 27, 2022Assignee: SOLIDIAN GMBHInventors: Johann Pfaff, Frank Werz

Patent number: 11358305Abstract: A method for producing a three-dimensional construction material component preferably having at least one curved surface. A plurality of spacers are arranged in a formwork. A textile reinforcement is supported on the spacers, such that the textile reinforcement has a defined position within a formwork interior of the formwork. A tensile force is applied via a tensioning device to the textile reinforcement in at least one tension direction. Construction material is introduced into the formwork interior and surrounds the textile reinforcement. The construction material is then hardened, wherein the tensile force is maintained during the hardening. During this process, the spacers are integrated into the construction material component. The tensioning device has at least one clamping unit for clamping an end portion of the textile reinforcement between two clamping surfaces. The clamping surfaces are provided on clamping insert bodies, which are of a plastic material of a defined hardness.Type: GrantFiled: June 22, 2018Date of Patent: June 14, 2022Assignee: Solidian GmbHInventor: Johann Pfaff

Patent number: 10934701Abstract: A positioning device and method for producing a construction material body. The positioning device holds and orients a reinforcement body consisting of a textile reinforcement within a formwork. The positioning device comprises first and second holding part groups arranged on a main body. At least one of the two holding part groups is movable between holding and release positions. In the holding position, each holding part acts on an associated location of engagement on the reinforcement body. In the release position, the distance between the holding parts is different from the distance between the locations of engagement on the reinforcement body, such that the positioning device is brought into engagement with the reinforcement body or can be removed therefrom. In the release position, independent handling of the positioning device relative to the reinforcement body is possible. To switch between the holding and release positions, an actuation device is provided.Type: GrantFiled: March 19, 2019Date of Patent: March 2, 2021Assignee: Solidian GmbHInventor: Johann Pfaff

Patent number: 10870992Abstract: A reinforcement arrangement and a method for producing a construction material body using the reinforcement arrangement. The reinforcement arrangement comprises a reinforcement body and at least one holding anchor unit. Each holding anchor unit is arranged or attached at the reinforcement body by a foot section. A holding section adjoining the foot section is moveable between a storage position and a function position. In the storage position, the holding section extends directly adjacent along the reinforcement body and abuts the reinforcement body at one or more locations. In the function position, a free end of the holding section opposite the foot section is larger than in the storage position. The holding section can be moved manually or self-acting from the storage position into the function position. The reinforcement body, the holding section, and the foot section are preferably embodied as textile-reinforced elements.Type: GrantFiled: April 18, 2019Date of Patent: December 22, 2020Assignee: Solidian GmbHInventor: Johann Pfaff

Publication number: 20190219367Abstract: The invention relates to a protective panel assembly and to a method for repairing an impact hole in the protective panel assembly. The protective panel assembly has three textile-reinforced concrete panels which are connected to one another via connecting elements to form a unit. The textile-reinforced concrete panels form an outer panel, an inner panel and an intermediate panel. Arranged between the outer panel and the intermediate panel is at least one fiber panel comprising fiber bundles of glass and/or aramid fibers incorporated in a synthetic matrix. An intermediate space exists between the intermediate panel and the inner panel. The intermediate space can be filled with air and/or a solid filler material which can be plastically and/or elastically deformed. Additional panels or layers can be omitted.Type: ApplicationFiled: July 24, 2017Publication date: July 18, 2019Inventor: Johann Pfaff

Patent number: 10253501Abstract: The invention relates to a spacer (1) for a reinforcement layer (16), a reinforcement system (29) for a concrete component (21), and a method for the production of a reinforcement system (29). The spacers (1) described allow especially mesh-type reinforcement layers (16) to be kept at a distance from other bodies (24, 28) in a particularly simple manner. The spacers (1) are fitted by inserting them into a mesh (8) of the reinforcement layer (16) and connecting them thereto by twisting.Type: GrantFiled: September 3, 2014Date of Patent: April 9, 2019Assignee: Solidian GmbHInventors: Uwe Mauz, Jochen Keinath, Johann Pfaff

Patent number: 10227777Abstract: The present invention relates to a method of producing a concrete component (15), to a prefabricated structural element (3), which serves as a semi-finished product for the production of the concrete component (15) made in this way, and to a corresponding concrete component (15). The method claimed involves the following steps: producing a prefabricated structural element (3) comprising first reinforcement structures (18), which feature textile reinforcement structures, and first thermal insulation elements (6), pouring concrete into a shell mold (13) to form a first concrete layer (11), lowering the prefabricated structural element (3) onto the first concrete layer (11).Type: GrantFiled: June 25, 2014Date of Patent: March 12, 2019Assignee: Groz-Beckert KGInventors: Roland Karle, Hans Kromer, Johann Pfaff

Publication number: 20170334162Abstract: A prefabricated concrete element (10) having a textile reinforcement (17) comprising fastening elements (12, 13, 14, 15), which are connected directly to the reinforcement (17). The fastening elements (12 to 15) can have a bent form and pass through a flat side of the prefabricated concrete element (10). The fastening elements can also have a straight or elongated form and emerge on narrow sides of a plate-shaped prefabricated concrete element (I 0). Because of the direct connection between the fastening element (12 to 15) and the reinforcement (17), the prefabricated concrete element can have an especially extensive and thin form and thus can be used as a façade panel.Type: ApplicationFiled: May 1, 2017Publication date: November 23, 2017Inventors: Roland Karle, Johann Pfaff, Hans Kromer

Patent number: 9663950Abstract: A concrete component includes a fiber reinforcement structure (12), formed by a grid arrangement (15). At least some of the rods extending in the X or Y direction are preferably designed as double rods having a joined cross-section or having sub-cross-sections separated from each other by a gap (20). Such double rods can be arranged in a grid structure both at right angles to each other and at other angles to provide a triangular structure, a hexagonal structure, or the like as a grid. Fiber reinforcement structures (12) made of a plastic-impregnated fiber material, such as epoxy-resin-bonded glass fibers having long fibers (endless fibers), in the particular rod longitudinal direction and without bonding among each other (ravings) can construct an adequately load-bearing composite with the concrete body (II). The steel rods can act as reinforcement, wherein harmful effects on the concrete, in particular wedge and gap effects, do not occur.Type: GrantFiled: May 7, 2013Date of Patent: May 30, 2017Assignee: GROZ-BECKERT KGInventors: Roland Karle, Hans Kromer, Johann Pfaff
