Title:
DEVICE FOR TIGHTENING REINFORCING ELEMENTS
Document Type and Number:
WIPO Patent Application WO2002016710
Kind Code:
A3
Abstract:
The invention relates to a device for tightening reinforcing elements, particularly unidirectional fibre laminates with a high strength of extension and one such elastic modulus connected to structures or parts of structures particularly structures with cement subjected to bending stress. The device comprises at least one tensioning means (SM) supplied with a mechanical drive. The tensioning means enters into contact with a first coupling member (K1) connected to at least one reinforcing element (V) and with a second coupling member (K2) connected to the structure (B). Non-uniform distribution of tension is avoided, especially along the width of the strip-type reinforcing elements, in addition to uncontrolled slackening of the tension during hardening of the conglutination before highly solid shear connection between the laminate and the concrete; correspondingly creation of tensioning devices of the above-mentioned variety for improved quality and reliability of the reinforcements in a rational manner of production. During the pre-tensioning flow of force between the connection of the first coupling member to the reinforcement element and the connection of the second coupling member to the structure, at least one pivoting connection (S1 or S2) is provided with at least one pivoting axis (A) arranged at an angle, especially an oblique angle, with respect to the tensioning device (X).
