Abstract
An duct coupler apparatus for sealing a bore of an anchor includes a coupler having an inner wall and a sealing mechanism affixed to the inner wall of the coupler. The sealing mechanism includes a shaft and sealing element affixed adjacent an end of the shaft. The sealing element is selectively movable between a retracted condition and an extended condition. The extended condition is adapted to be in sealing relation with an inner wall of the bore of the steel structure. The apparatus includes a nut threadedly affixed to the shaft so as to bear against the sealing element. The nut is rotatable on the shaft so as to urge against the sealing element so as to cause the sealing element to be in the extended or expanded condition.
Claims17
An apparatus comprising:
- a steel structure having a bore formed therein, said steel structure having a facing surface;
- a duct;
- a duct coupler, said duct coupler having an end positioned against said facing surface of said steel structure, said duct coupler having an inner wall extending around said duct;
- and
- a sealing mechanism affixed to said inner wall of said duct coupler, said sealing mechanism comprising:
- a shaft extending in a direction toward said facing surface of said steel structure;
- and
- an sealing element affixed to said shaft, said sealing element positioned within said bore of said steel structure, said sealing element selectively movable between a retracted condition and an extended condition, said extended condition for being in sealing relationship with a wall of said bore.
An apparatus for sealing an interior of a bore of a steel structure, the apparatus comprising:
- a coupler having an inner wall;
- and
- a sealing mechanism affixed to said inner wall of said coupler, said sealing mechanism comprising:
- a shaft,
- a sealing element affixed adjacent an end of said shaft, said sealing element selectively movable between a retracted condition and an extended condition, said sealing element adapted to be in sealing relation with an inner wall of the bore of the steel structure when in the extended condition;
- and
- a ring threadedly affixed to said inner wall of said coupler.
An apparatus for sealing an interior of a bore of a steel structure, the apparatus comprising:
- a coupler having an inner wall;
- and
- a sealing mechanism affixed to said inner wall of said coupler, said sealing mechanism comprising:
- a shaft;
- and
- a sealing element affixed adjacent an end of said shaft, said sealing element selectively movable between a retracted condition and an extended condition, said sealing element adapted to be in sealing relation with an inner wall of the bore of the steel structure when in the extended condition, said coupler having an annular channel at an end thereof, said annular channel having a seal therein, said coupler adapted to be positioned against a facing surface of the steel structure such that the seal is in liquid-tight sealing relationship with the facing surface of the steel structure.
