    摘要: A concrete tensioning band is disposed on a surface of unhardened concrete and tensioned by being attached to a clamp disposed on the base, and then displacing the clamp by a drive mechanism disposed on the clamp. Such displacement serves to tension the band. Spacers are positioned between the clamp and the base to hold the clamp in the displaced state while the drive mechanism is removed and an anchor device is fixed to the band to anchor the band to the base. Then, the clamp is removed.

    摘要: A reinforced or prestressed concrete structure is strengthened and/or restored by attaching a strip-shaped tensional member thereto. Prior to attaching the tensional member, a central portion thereof is prestressed. Then, the tensioned central portion is bonded to a concrete surface of the concrete structure by a first adhesive having a high deformation modulus. Thereafter, the non-prestressed end portions of the tensional member are bonded to the concrete surface by a second adhesive having a low deformation modulus, whereby the second adhesive is substantially less deformable than the first adhesive.
