Device for anchoring the end of at least one rod of fibrous composite material used as a tensioning member in prestressed concrete constructions

摘要

1. Apparatus (10) for the end anchorage of at least one bar (11 or 12 or 13) serving as a prestressing member in prestressed-concrete construction and made of a fibre composite, comprising a hollow anchoring body (14) which can be secured to the concrete body (17) and in which there is arranged a clamping body (20, 21 or 21, 22 or 22, 23) which extends over a length section of the bar and through which the bar penetrates, on which clamping body (20, 21 or 21, 22 or 22, 23) transverse compressive forces, acting at right angles to the longitudinal axis of the bar, are produced by means of a clamping device formed by a wedge-plate pair (30, 31), which transverse compressive forces make a frictional connection between bar and clamping body or the hollow anchoring body, characterized in that a device (32 to 34) for limiting transverse compressive forces is provided which has a limit-value member (37) and with which a predeterminable magnitude of the transverse compressive forces can be set.
