    Abstract: A concrete construction is made by 3D concrete printing and comprises: - two or more layers (100, 102) of cementitious material extruded one above the other, and - a reinforcing structure (104) reinforcing the two or more layers (100, 102). The reinforcing structure (104) has a length and a height. The reinforcing structure (104) comprises at least two flexible longitudinal elongated steel elements (208, 210, 308, 310) running in lengthwise direction. The reinforcing structure (104) further comprises one or more flexible transverse steel elements (214, 314) forming an angle with the lengthwise direction so that these flexible transverse steel elements (214, 314) are present in the two or more layers (100, 102). The structure (104) further comprises a positioning element for positioning the at least two flexible longitudinal elongated elements (208, 210, 308, 310) and the flexible transverse steel elements (214, 314), a polymer coating or yarns making stitches. The polymer coating or the stitches are applied on the at least two flexible longitudinal elongated steel elements (208, 210, 308, 310), on the flexible transverse steel elements (214, 314) and on the positioning element thereby making a bond between the at least two flexible longitudinal elongated steel elements (208, 210, 308, 310), the flexible transverse steel elements (214, 314) and the positioning element. A concrete construction made by 3D concrete printing comprises: - two or more layers (100, 102) of cementitious material extruded one above the other, and - a reinforcing tape (104) reinforcing at least two of the layers (100, 102). The reinforcing tape (104) comprises at least one steel cord (106). The presence of a steel cord (106) gives more flexibility to the reinforcement.

    Abstract: Die Erfindung betrifft eine Sandwichstruktur (1) mit eingelassenem Verbindungselement (6) sowie ein Verfahren zu dessen Herstellung. Die erfindungsgemäße Sandwichstruktur (1) mit zwei Deckschichten (2, 3) und einem dazwischen angeordneten Kern (4) weist zur Verbindung mit weiteren Bauteilen wenigstens ein Verbindungselement (6) auf, wobei das Verbindungselement (6) ein an einer Deckschicht (2) in die Sandwichstruktur (1) eingelassenes Insert (7) umfasst, dessen Einlasstiefe kleiner ist als die Dicke des Kerns (4). Das Verbindungselement (6) ist dabei mit der Außenseite der Deckschicht (2), über die das Verbindungselement (6) eingelassen ist, bündig nachgearbeitet oder aus der Deckschicht (2) hervorstehend. Das erfindungsgemäße Verfahren zur Herstellung einer solchen Sandwichstruktur (1) umfasst die Schritte: a) Herstellen eines Sacklochs (5) ausgehend von einer Deckschicht (2) der Sandwichstruktur (1); b) Einbringen des Verbindungselementes (6) in das Sackloch (5) und Befestigen des Verbindungselements (6) darin; und c) Nacharbeiten des Verbindungselementes (6), sodass es bündig mit der Deckschicht (2) oder um eine vorgegebene Höhe aus der Deckschicht (2) hervorstehend ist.

    Abstract: A method for additive manufacturing of a three-dimensional object (1990) includes: a) identifying a set of sequentially extending planar cross-sectional shapes of the three-dimensional object; b) cutting a metal sheet (2212) into a plurality of planar metal pieces (2216), each metal piece cut to a metal piece shape corresponding to a respective one of the cross-sectional shapes, wherein the metal sheet has a first face with a first plurality of barbs extending therefrom, and an opposed second face with a second plurality of barbs extending therefrom; c) cutting a substrate sheet (2218) into a plurality of planar substrate pieces (2222), each substrate sheet cut to a substrate piece shape corresponding to a respective one of the cross-sectional shapes; and d) positioning the metal pieces and the substrate pieces in facing relation in an alternating pattern and in sequential order, and pressing the metal pieces and substrate pieces together to force the barbs to penetrate the substrate pieces.

    Abstract: The present invention concerns an innovative anti- scratch and anti-slip device (1) for realizing the lifting of a load with the fork (10) of a lift, for example a fork lift. The device is realized through the overlapping of three different layers. In particular, a first magnetic layer (2) is included so as to result magnetically applicable to the fork. A second external layer (4) covers the first layer (2) and is realized of a rubber material since it has to be in contact directly with the load. The rubber guarantees seal and does not scratch the load. Last, the third layer is an intermediate metallic layer (3), interposed between the first (2) and the second layers (4) so as to duly stiffen the device.

    Abstract: An engineered wood product with at least one engineered-wood substrate or core layer (such as, but not limited to, OSB), with a connectivity layer configured to reflect RF signals (e.g., wifi and/or cellular signals), thereby enhancing connectivity in adjacent or proximate spaces or areas. The connectivity layer may be a metallic material, such as, but not limited to, aluminum or copper. The layer may be a sheet or film or foil of the metallic material applied to the surface(s), or integrated into the interior, of the substrate or core layer. The layer also may be a coating or deposited layer. A connectivity layer may be "sandwiched" between two or more engineered-wood substrates, thereby forming a composite panel or product. The surface of the connectivity layer may be embossed or patterned.
