Abstract
An insulated concrete form having spaced sidewalls joined by form ties to define a first interior cavity therebetween for receiving poured concrete, the form ties including interior fastening plates positioned in between the spaced sidewalls. The interior fastening plates provide a backing surface to which forming structures can be easily and efficiently secured to define a second interior cavity in between the forming structure and one of the sidewalls, the second interior cavity having thickness less than the first interior cavity so as to define a form for making a recess in the resulting concrete portion of the wall.
Claims13
An assembly for construction of structures utilizing insulated concrete forms comprising:
- an insulated concrete form comprising:
- a first sidewall having a first interior surface, a second sidewall having a second interior surface, and wherein a height of the first sidewall is less than a height of the second sidewall;
- a plurality of form ties, wherein the plurality of form ties connect the first sidewall to the second sidewall such that the first sidewall is spaced from the second sidewall to define a first interior cavity in between the first interior surface of the first sidewall and the second interior surface of the second sidewall, wherein a thickness of the first interior cavity is defined in a lateral direction between the first interior surface of the first sidewall and the second interior surface of the second sidewall;
- the plurality of form ties comprising a first form tie, the first form tie having a first side member secured to the first sidewall, a second side member secured to the second sidewall, an upper lateral member, and a lower lateral member, wherein the upper and lower lateral members are positioned transverse the first and second side members, and wherein the lower lateral member connects the first side member to the second side member;
- an interior fastening plate secured to the first form tie, the interior fastening plate having a first planar face, wherein the interior fastening plate is oriented such that the first planar face faces in a lateral direction toward the first interior surface of the first sidewall, and wherein the interior fastening plate is spaced from the second interior surface of the second sidewall;
- a forming structure having an interior forming surface, the forming structure is secured to the interior fastening plate and oriented such that the interior forming surface of the forming structure faces toward the second interior surface of the second sidewall, and wherein the interior forming surface is spaced from the second sidewall to define a second interior cavity in between the interior forming surface of the forming structure and the second interior surface of the second sidewall, wherein a thickness of the second interior cavity is defined in a lateral direction between the interior forming surface of the forming structure and the second interior surface of the second sidewall;
- and
- wherein the thickness of the first interior cavity is greater than the thickness of the second interior cavity.
5 more elements
A method for construction of structures utilizing insulated concrete forms comprising:
- stacking a first insulating concrete form on a second insulating concrete form,
- wherein the first insulating concrete form comprises,
- a first sidewall having a first interior surface, a second sidewall having a second interior surface, and a plurality of form ties, wherein the plurality of form ties connect the first sidewall to the second sidewall such that the first sidewall is spaced from the second sidewall to define a first interior cavity in between the first interior surface of the first sidewall and the second interior surface of the second sidewall;
- wherein the plurality of form ties comprise a first form tie, the first form tie having a first side member secured to the first sidewall, a second side member secured to the second sidewall, an upper lateral member, and a lower lateral member, wherein the upper and lower lateral members are positioned transverse the first and second side members, and wherein the lower lateral member connects the first side member to the second side member, and
- an interior fastening plate secured to the first form tie, the interior fastening plate having a first planar face, wherein the interior fastening plate is oriented such that the first planar face faces in a lateral direction toward the first interior surface of the first sidewall, and wherein the interior fastening plate is spaced from the second interior surface of the second sidewall;
- removing a portion of the first sidewall such that the first planar face of the interior fastening plate is accessible from a lateral direction from a first side of the insulated concrete form;
- securing a forming structure having an interior forming surface to the first planar face of the interior fastening plate such that the interior forming surface of the forming structure faces toward the second interior surface of the second sidewall and wherein the interior forming surface is spaced from the second sidewall to define a second interior cavity in between the interior forming surface of the forming structure and the second interior surface of the second sidewall, wherein a thickness of the second interior cavity is defined in a lateral direction between the interior forming surface of the forming structure and the second interior surface of the second sidewall, and wherein the thickness of the first interior cavity is greater than the thickness of the second interior cavity.
4 more elements
An insulated concrete form comprising:
- a first insulated foam sidewall having generally vertical, height dimension section;
- a second insulated sidewall spaced from the first insulated sidewall by a first distance to form a cavity between said first and second sidewalls for receipt of concrete, said second sidewall having a second generally vertical, height dimension section at least in part greater than said first sidewall height dimension section;
- at least one connecting member for connecting the first sidewall to the second sidewall to maintain said first sidewall spaced from said second sidewall to thereby form said cavity between said first sidewall and said second sidewall, said connecting member including an intermediate concrete form member intermediate the first and second sidewalls, said intermediate concrete form member in combination with the first sidewall generally vertical, height section defining at least a portion of said cavity having a generally vertical dimension less than the second sidewall vertical, height dimension whereby said insulated concrete form in combination with concrete in said cavity includes at least a section having a generally vertical dimension less than another section vertical dimension.
