Abstract: A tie anchor for strip-type tension members includes an anchor body disposed on at least one side of the tension member. The anchor body includes a plurality of clamping blocks arranged at a distance from each other in a longitudinal direction of the tension member. The clamping blocks are connected to tension member by adhesive and/or friction (clamping friction). An end-most (final) one of the clamping blocks is attached to a fixed abutment. Adjacent clamping blocks are interconnected by expansion members whose spring stiffness becomes progressively stronger toward the end-most clamping block.

Abstract: The invention relates to a tie rod for a strip-type tension member (1), used in the building trade, and consisting especially of fibre-reinforced plastic lamellae. Said tie rod comprises at least one anchoring body (2) which is positively connected to the tension member (1) by means of adhesion and/or friction, and can be supported on a fixed abutment. The anchoring body (2) comprises a plurality of clamping blocks (3) which are arranged at a distance from each other in the longitudinal direction of the tension member and are connected to said tension member (1) by means of adhesion and/or friction. One of said clamping blocks is supported on the fixed abutment (7), and the clamping blocks are interconnected by extension sections (9) having different spring stiffnesses, the spring stiffnesses of said extension sections (9) increasing towards the end of the tension member (1).

Abstract: A process for the production of refractory materials containing SiALON and carbon or SiALON/SiC and carbon. The process for producing a refractory material containing SiALON and carbon includes heating a molding containing silicon, aluminum, aluminum oxide and carbon to a temperature of 1380.degree. C. at a total atmospheric pressure of less than or equal to 0.1 MPa in an atmosphere containing predominantly nitrogen and containing a concentration of 0 to 5 vol. % of carbon monoxide, subsequently increasing the concentration of carbon monoxide to between 10 and 30 vol. % and heating the molding to a temperature of 1500.degree. C. at a total atmospheric pressure of less than or equal to 0.1 MPa; and subsequently controlling the concentration of carbon monoxide to be between 0 and 10 vol. % and heating the molding to a temperature of 2200.degree. C. at a total atmospheric pressure of greater than or equal to 0.1 MPa.
