COMPRESSIBLE EXPANSION JOINT STRIP

摘要

A method and apparatus for sealing gaps in concrete work or like material in which the gaps are formed by direct insertion of a sealing strip (80) into the unset concrete (58) by downward pressing of the sealing strip into the surface (58a) of the unset concrete. The strip (80) is reinforced during insertion by a reinforcing element (72) which engages the strip and which is removed prior to setting of the concrete. The concrete closes against the side surfaces of the strip prior to setting. The reinforcing element may be separate from or part of the apparatus.
