Abstract
Apparatus for tying together concrete form panels includes an elongated tie and means attachable to a concrete form panel for anchoring the tie to restrain relative movement between the tie and the form panel. Means are provided both to facilitate engagement and release of the tie by the clamping member and to compensate for misalignment between the tie and the form panel and between opposing form panels.
Claims39
Concrete form panel tying apparatus for restraining outward movement of a concrete form panel with respect to a tie passing outwardly through a form opening in said form panel, said apparatus comprising:
- a bearing member attachable to said form panel, said bearing member having an opening alignable with said form opening, and an outwardly facing first bearing surface,
- a tie extending through said bearing member opening,
- an outer end portion on said tie having a first transverse dimension,
- an inner end portion on said tie located inwardly of said outer end portion and having a second transverse dimension less than said first transverse dimension,
- an outwardly sloped tie surface extending between said outer end portion and said inner end portion, said outwardly sloped tie surface being arcuate in cross-section,
- anchoring means for engaging said tie, said anchoring means being adjustably positioned between said sloped tie surface and said first bearing surface to compensate for misalignment of the tie with respect to the bearing member and comprising a clamping member and a second bearing surface engageable with said first bearing surface, said clamping member having a clamping member recess of transverse dimension greater than said second transverse dimension and less than said first transverse dimension, said clamping member recess being defined by an outwardly sloped clamping surface of arcuate cross-section complementary to said tie surface and engageable therewith, said clamping member being movable radially with respect to said tie between a clamping position wherein said clamping surface is in engagement with said tie surface to restrain said concrete form panel against outward movement with respect to said tie and a nonclamping position wherein said clamping surface and said tie surface are not engaged with one another.
Apparatus for anchoring a concrete form panel to an elongated tie to restrain outward relative movement of the panel with respect to the tie, said anchoring apparatus comprising:
- a load bearing member attachable to the outside of the form panel and having an opening through which said tie is extendable,
- a clamping member releasably clampingly engageable with a portion of said tie that is extending outwardly through said opening, and
- a mounting member attached to said clamping member and havng a second opening through which said tie is extendable, said mounting member being interposed between said bearing member by adjustable attaching means, whereby adjustment between the clamping member and the bearing member is facilitated to compensate for misalignment of the tie with respect to the bearing member.
