Abstract
A spacer device includes a spacer having a n aperture through a bottom-side that sits against the surface of the form. The aperture is configured for providing a threaded-fixture having internal-threads, the threaded-fixture including a securing assembly insertable into the threaded-fixture. The securing assembly includes external-threads for mating with the internal-threads of the threaded-fixture. The spacer device is useful for providing a novel securing means for securing with reinforcing steel in a spaced relation for in a concrete structure or other such structure.
Claims11
A reinforcing steel spacer device with an improved securing means for use in a concrete structure, the spacer device comprising:
- a spacer having a front-side opposite a rear-side, a left-side opposite a right-side, and a bottom-side opposite a top-side, the spacer including;
- a semi-circular-recess configured to receive and support rebar, the semi-circular-recess intersecting the top-side;
- an aperture through the bottom-side, and including a first-end, a second-end, and a length therebetween, the aperture configured for providing a threaded-fixture having internal-threads;
- a left-recess intersecting the left-side;
- and
- a right-recess intersecting the right-side, such that the right-recess mirrors the left-recess across an axis defined by the aperture;
- wherein each the left-recess and the right-recess intersect both the front-side and the rear-side;
- the threaded-fixture further including a securing assembly insertable into the threaded-fixture, the securing assembly including external-threads for mating with the internal-threads of the threaded-fixture.
An adaptor able to be fitted to an existing rebar chair by being embedded within it to provide an opening in a finished slab for providing a securing means with use in a concrete structure, the adaptor comprising:
- a threaded-fixture having internal-threads and fitted within a rebar chair, and
- a securing assembly that is insertable into the threaded-fixture, the securing assembly including external-threads for mating with the internal-threads of the threaded-fixture;
- wherein the threaded-fixture includes an incaptured threaded-nut;
- wherein the threaded-fixture includes a torque preventing means;
- and
- wherein the torque preventing means includes a T-shaped configuration.
A spacer device, the spacer device comprising:
- a spacer having a front-side opposite a rear-side, a left-side opposite a right-side, and a bottom-side opposite a top-side, the spacer including;
- a semi-circular-recess configured to receive and support rebar, the semi-circular-recess intersecting the top-side;
- an aperture through the bottom-side, and including a first-end, a second-end, and a length therebetween, the aperture configured for providing a threaded-fixture having internal-threads;
- a left-recess intersecting the left-side;
- and
- a right-recess intersecting the right-side, such that the right-recess mirrors the left-recess across an axis defined by the aperture;
- wherein each the left-recess and the right-recess intersect both the front-side and the rear-side;
- the threaded-fixture further including a securing assembly insertable into the threaded-fixture, the securing assembly including external-threads for mating with the internal-threads of the threaded-fixture;
- further comprising a hole for threading a zip tie therethrough;
- wherein the hole transverses intersectionally of the semi-circular-recess from the front-side to the rear-side;
- wherein the threaded-fixture includes an incaptured threaded-nut;
- wherein the spacer is rigid;
- wherein the length of the aperture extends approximately half-way from the bottom-side to the top-side of the spacer;
- and
- wherein the spacer is substantially rectangular as defined by the front-side opposite the rear-side, the left-side opposite the right-side, and the bottom-side opposite the top-side.
