Abstract: A seal for a lead-through for a tie rod through a panel formwork element. The seal includes a sleeve, a sealing element and a sliding tube, which are disposed on the tie rod and, together with the tie rod, are placed through the panel formwork element from a rear side, so that the sealing element exits the panel formwork element on a front side and, after brief pulling back of the tie rod, provides sealing between the sleeve and the panel formwork element, for one-sided anchoring.

Abstract: For one sided anchoring of two casing elements the invention proposes an anchor including an anchor rod with a thread and an anchor head that is rotationally fixed at the anchor rod to drive the anchor to rotate. A first reaction bearing is arranged at a fixed distance from the anchor head, wherein an enveloping tube that is arrangeable on the anchor rod is supported at the first reaction bearing, wherein a sleeve that forms a second reaction bearing for a casing element that is remote from the anchor head is arranged at another end of the enveloping tube. The invention facilitates one sided anchoring.

Abstract: The invention relates to a casing shell element for casing concrete and proposes a rotatable anchor counter piece for anchoring wherein the anchor counter piece includes two pass through holes intersecting each other which are optionally alignable with an anchor hole in a casing shell of the casing shell element for inserting an anchor by rotating the anchor counter piece. A pass through hole includes an internal thread for threading in a non-illustrated anchor and another pass through hole is configured without a thread for inserting an anchor onto which a non illustrated anchor nut is threaded for attachment purposes.

Abstract: A method of repairing the surface of a formwork panel made of plastic. The invention provides for a surface coating of the formwork panel to be removed by machining, for example by a milling cutter, and for the formwork panel to be recoated with the same thickness as the removed surface coating. For the repair, the formwork panel can remain in its frame.

Abstract: The invention relates to a structural member and a process for producing a structural member with at least one layer of plastic and with a layer inside the structural member of a material that has a substantially higher modulus of elasticity than plastic. The member also has at least one system plane that is part of the structural member and along which the structural member has substantially homogenous properties and a substantially homogeneous structure. The invention is characterized in that along the system plane, at least one inner layer and a respective outer layer consisting of plastic are provided between which two layers each separated from each other and traversing the system plane with the second higher modulus of elasticity are provided.

Abstract: A structural member, in particular for wall and ceiling shuttering, has a working surface and a structural frame on which the working surface is mounted; and frame members perpendicular to the working surface that form the structural frame. The working surface and the structural frame are formed integrally as an injection molded part.

Abstract: A construction element has a thickness substantially less than at least one of its other dimensions. In terms of weight, the construction element is comprised of more than 50% plastic and less than 50% pieces of metal band. The pieces of metal band are single pieces, flat, bent into a three dimensional configuration, and randomly oriented and embedded in the plastic. The pieces of metal band are shorter than the construction element is thick.

Abstract: A construction element has the dimensions of formwork panel sheets of elemental concrete formwork and a thickness substantially less than at least one of its other dimensions. In terms of weight, the construction element is comprised of more than 50% plastic and less than 50% small, thin pieces of metal. The pieces of metal are distributed statistically evenly in the plastic, shorter than the construction element is thick, and preferably made of aluminum. The thermal transfer coefficient of the construction element is at least that of wood/plastic casting boards.

This takes place by a foamed plastic layer bonded with solid plastic outer shell regions 12, 13 and metal mats 22, 23 laid therein. The plastic contains pieces of metal strip that are bent in a three dimensional configuration.

Abstract: An elongate construction element according to the invention is made of plastic which has a first, low modulus of elasticity, and a lamination of a material which has a second, significantly higher modulus of elasticity inside the construction element. The construction element has at least one system plane along which the construction element has essentially homogeneous characteristics and is essentially homogeneously constructed. The lamination lies on both sides of the system plane and crosses through the latter at least at one point. The cross-sectional areas of the lamination and the plastic are inversely proportional functions of the effective moduli of elasticity of the plastic and of the lamination so that the flexural rigidities of the cross-sectional areas are essentially equal. The lamination is at least essentially continuous.

Abstract: Webs for reducing bending in board-shaped construction elements when in use have their main direction of load perpendicular to the board plane. The devices have a sandwich of at least one first material layer, one second material layer, and one third material layer. The third material layer lies between the other two material layers and has a substantially higher coefficient of heat expansion than the other two material layers, so as to set up contracting biasing forces in the third material layer. The third material is made of a sheet metal strip. The two other materials are made of thermosetting plastic, which sets at a temperature considerably above the working temperature of the construction element.
