Abstract: Shear force anchor for transmitting shear forces transversely to the longitudinal direction of a structural element within structural elements made primarily of concrete, comprising: a connection section for introducing at least one shear force into the shear force anchor which is connected to at least one load introduction section, which can be contacted to the structural element to transmit at least one force component in the direction of the shear force to be transmitted to the structural element. In order to transmit large shear forces while at the same time having a slim design of the structural element, the connection section is additionally spaced in the direction of the shear force to be transmitted from the load introduction section.

Abstract: A turnbuckle for joining structural elements, in particular prefabricated concrete parts, which is formed substantially in the shape of a shell and has a housing chamber accessible at least from outside via an access opening and, in addition, passage sections which are preferably located opposite one another and open into the housing chamber and which are preferably configured as passage openings for a fixing element to be pushed through. In addition, a kit for joining structural elements, method for joining structural elements, an arrangement for joining structural elements and a method for preparing structural elements.

Abstract: Distance piece, preferably for the manufacture of hollow or laminated walls, with at least three rods that are connected to each other, and where each rod has at least one supporting section, and the supporting sections of the three rods are spaced apart from each other to thus form a supporting plane.

Abstract: The invention relates to a formwork system with a formwork support preferably for supporting at least one formwork piece, and a magnet device, movably coupled to the formwork support, for fixing the position of the formwork support on a formwork base, wherein the magnet device has a magnet member, which can be transferred between a raised position, in which the formwork support can be moved together with the magnet device relative to the formwork base, and a lowered position in which the formwork system is magnetically fixed relative to the formwork base. Advantageously, with the present invention the magnet device for transferring the magnet member between the raised position and the lowered position is movable relative to the formwork support.

Abstract: The invention relates to a holding device, preferably a shell device, which comprises a magnet that can be transferred from a locking position, in which the magnet is preferably operatively connected to a magnetizable shell support so as to magnetically act upon it, to a detach position in which the magnet is spaced apart from the shell support. The aim of the invention is to simplify a holding device of the above-described kind. The magnet, for the purpose of transferring it from the locking position to the detach position, is mounted so as to be rotatable about a swiveling axis in such a manner that in the detach position it is disposed so as to be swivelable via-à-vis the locking position.
