  • Patent number: 6408585
    Abstract: Random-shaped tiles are joined in an arbitrary array onto a front plane of a metal plate having holes, the metal plate being fixed to a backing plate. The random-shaped tiles are supported by supporting pieces of attaching pieces attached to the metal plate. The weight of the random-shaped tiles is received at the lower edge portion thereof by the supporting pieces, and the movement thereof in the direction of peeling away (forwards) is restricted at the upper edge portion of the random-shaped tiles by the supporting pieces. The random-shaped tiles can be joined to the metal plate having holes in a free array, and work can proceed speedily without any sagging during the joining work. Following joining, the random-shaped tiles are shielded from a good deal of vibrations and movement applied to the building frame, while being held in a secure joining state to the metal plate having holes.

  • Patent number: 6015953
    Abstract: An end of a conductor having a stranded conductor layer wound around a tension member made of resin-reinforced carbon fiber is cut back to expose the end of the tension member. The exposed end of the tension member is inserted into a metal fitting having multiple longitudinal slits. A metal sleeve is then fit over the metal fitting and also partially over the stranded conductor layer before compress-fitted into place. Accordingly, it is possible to attach, with good workability and sufficient tensile strength, a conductor that has a tension member made of resin-reinforced carbon fiber.
