<p>Apparatus for anchoring at least one oblong tension member (5) of a fibre (e.g. aramid) reinforced resin matrix. It comprises a clamping member (3, 4) made of synthetic plastic material and positioned in a housing (1) for exerting an external drawing force in the longitudinal direction of the tension member (5), in which both the clamping member (3, 4) and the housing (1) or an element connected thereto are provided with cooperating contact surfaces slanting with respect to the tension member (5) for transferring said external drawing force to the tension member (5), the slanting surfaces being directed at a sharp angle alpha to the longitudinal direction of the tension member (5) extending from the inside (10) of the apparatus to an other point to attachment, particularly for use in pre-stressed concrete. An apparatus which can be readily produced and which may used a number of times can be obtained, if (A) the clamping member (3, 4) consists of a block-shaped element which is already solidified, and in particular substantially pore-free, before the introduction thereof into the housing (1), (B) it is releasably connected, during pre-stressing, to the tension member (5) directly through frictional contact and compressive forces, and (C) preferably, it extends over at least 50-80% of the length of the housing (1). n</p> |
