Concrete form panel tying apparatus

Concrete form panel tying apparatus for restraining outward movement of a concrete form panel with respect to a tie passing therethrough, said apparatus comprising:

• a tie extendable outwardly through said concrete form panel,
• 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,
• a tie surface extending between said outer end portion and said inner end portion at an angle to the longitudinal axis of said tie,
• clamping means for engaging said tie, said clamping means comprising first and second clamping members, said first clamping member having a first recess and said second clamping member having a second recess, said first and second recesses being defined at least in part, respectively, by first and second clamping member surfaces disposed at angles to the longitudinal axis of said tie and complementary to said tie surface, said first and second recesses being alignable with one another to define an aperture having a transverse dimension greater than said second transverse dimension and less than said first transverse dimension whereby said inner end portion can be received in said aperture with said tie surface in engagement with said clamping member surfaces, said clamping members being movable radially with respect to said tie between engaged positions wherein said tie surface is in engagement with said clamping member surfaces and a disengaged position wherein said tie surface and said clamping member surfaces are disengaged from one another, and
• means for releasably holding said clamping members in said engaged position.

Concrete form panel tying apparatus for restraining outward movement of a concrete form panel which comprises:

• a tie extendable outwardly through an opening in the concrete form panel, said tie including an inner part and an outer part threadedly connected to said inner part for longitudinal movement relative thereto,
• an outer end portion on said outer part having a first transverse dimension,
• an inner end portion on said outer part located inwardly of said outer end portion and having a second transverse dimension less than said first transverse dimension,
• an outwardly inclined tie surface extending between said outer end portion and said inner end portion,
• clamping means operatively associated with said tie and movable betweens engaged and disengaged positions relative to said tie, said clamping means being positionable between said inclined tie surface and the concrete form panel and having an inclined clamping surface complementary to said inclined tie surface and engaging said inclined tie surface when in said engaged position to restrain said panel against outward movement relative to said tie.

Concrete form panel tying apparatus which comprises:

• an elongated tie extendable outwardly through an opening in a concrete form panel, said tie having a threaded rod and a nut threadedly connected to said rod for longitudinal movement relative thereto,
• said nut having a transverse external groove defined by a pair of opposed inner and outer shoulders extending transversely of said tie,
• a load bearing member adapted to be connected to the exterior of said form panel, said load bearing member having an interior side facing said form panel, an exterior side facing away from said form panel, and an opening through which said tie extends, and
• a clamping member connected to said load bearing member on the exterior side thereof and releasably movable into clamping relation to the shoulders of said groove when said nut is positioned with said groove adjacent to said exterior side to restrain longitudinal movement of said clamping member, said bearing member and the concrete form panel relative to said nut while permitting axial rotation of said nut relative to said clamping member to effect said longitudinal movement of said nut relative to said rod thereby adjusting the positioning of the concrete form panel relative to said rod.

Concrete form panel tying apparatus for restraining outward movement of a concrete form panel with respect to a tie passing therethrough, said apparatus comprising:

• a tie extendable outwardly through an opening in said concrete form panel;
• an outer end portion on said tie having a first transverse dimenion,
• 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 inclined transverse shoulder extending between said outer end portion and said inner end portion and curved about the longitudinal axis of said tie;
• and
• clamping means operatively associated with said tie for engaging said tie,
• said clamping means being positionable between said transverse shoulder and said concrete form panel and comprising a clamping member having a recess of transverse dimension greater than said second transverse dimension and less than said first transverse dimension to accommodate said tie therein, said clamping member being at an angle to the longitudinal axis of said tie, said recess being defined at least in part by an outwardly inclined clamping surface complementary to said transverse shoulder and engageable therewith, said clamping member being movable radially with respect to said tie between an engaged position wherein said clamping surface is in engagement with said transverse shoulder to restrain said concrete form panel against outward movement with respect to said tie and a disengaged position wherein said clamping surface and said transverse shoulder are not engaged with one another.
