Concrete wall form with flexible tie system
View Patent ↗A concrete wall form that can readily be used with different types of form ties systems to construct parallel form sections for receiving poured concrete. The form includes first and second tie rod engaging portions configured to receive first and second types of tie rods, respectively. In one aspect of the invention, the first tie rod engaging portion is configured to receive frangible tie rods in the form of elongate wires or flat strips. In another aspect of the invention, the second tie rod engaging portion is configured to receive tie rods having threaded bars that extend through tubes and between parallel wall form sections.
1. A system for forming a concrete structure, comprising:
a plurality of forms configured to be secured togeather in a generally edge-to-edge arrangement and also in a spaced, confronting arrangement to define a space for receiving poured concrete therebetween:
each said form including at least one first tie rod engaging portion and at least one second tie rod engaing portion diaposed on said form, such that tie rods engaged with said first end second tie rod engaging portions extend through said space for receiving poured concrete;
said first tie rod engaging portion configured to receive a tie rod of a first type, said second tie rod engaging portion configured to receive a tie rod of a second type;
wherein the first type of tie rod is a non-removable tie rod with frangible ends, and the second type of tie rod is removable from said space;
at least one bracket couplable with one of said plurality of forms, proximate one of said second tie rod engaging portions, said bracket and said second tie rod engaging portion cooperating to support a tie rod of the second type on said frame; and
wherein said bracket comprises a bracket plate and first and second leg members extending in a direction normal to said bracket plate, said first leg member configured to engage said first tie rod engaging portion, said second leg member configured to engage said second tie rod engaging portion.
2. A concrete form, comprising:
at least one form section adapted for use in combination with at least one other form section to define a space for receiving poured concrete;
at least one first tie rod engaging portion disposed on said form section and configured to receive a tie rod of a first type;
a second tie rod engaging portion disposed on said form section and configured to receive a tie rod of a second type; and
at least one bracket couplable to said form section, proximate said second tie rod engaging portion, said bracket and said second tie rod engaging portion cooperating to support a tie rod of the second type on said form section;
wherein said bracket comprises a bracket plate and first and second leg members extending in a direction normal to said bracket plate, said first leg member configured to engage said first tie rod engaging portion, said second leg member configured to engage said second tie rod engaging portion.
3. A concrete form, comprising:
at least one form section adapted for use in combination with at least one other form section to define a space therebetween for receiving poured concrete;
at least one first tie rod engaging portion disposed on said form section and configured to receive a tie rod of a first type such that the first type of tie rod extends through said space for receiving poured concrete; and
a second tie rod engaging portion disposed on said form section and configured to receive a tie rod of a second type, such that the second type of tie rod extends through said space for receiving poured concrete;
wherein the first type of tie rod is a non-removable tie rod with frangible ends, and the second type of tie rod is removable from said space;
at least one bracket couplable to said form section, proximate said second tie rod engaging portion, said bracket and said second tie rod engaging portion cooperating to support a tie rod of the second type on said form section; and
wherein said bracket comprises a bracket plate and first and second leg members extending in a direction normal to said bracket plate, said first leg member configured to engage said first tie rod engaging portion, said second leg member configured to engage said second tie rod engaging portion.
4. The concrete form of claim 3 , further comprising a frame associated with each of said form sections and wherein said first tie rod engaging portion comprises a at least one notch formed into said frame.
5. The concrete form of claim 3 , further comprising a frame associated with each of said form sections and wherein said second tie rod engaging portion comprises a plate attached to said frame, said plate including an aperture formed through said plate end sized to receive a tie rod of the second type.
6. The concrete form of claim 3 , wherein said first tie rod engaging portion as configured to receive a tie in the form of an elongate wire or generally flat strip.
7. The concrete form of claim 3 , wherein said second tie engaging portion is configured to receive a tie in the form of a threaded bar.
8. The concrete form of claim 4 , further comprising
a facing member secured to said frame and defining an interface for molding an outer surface of the poured concrete.
