Rebar positioner

Abstract

An apparatus for aiding in the positioning of a reinforcing bar or “rebar” within a core of a masonry block unit includes a mid-section defining at least one substantially confined area for receiving the reinforcing bar therein, and first and second opposed arms extending outward from the midsection. Each of the arms includes a first section extending outward from substantially opposite ends of the mid-section. The first sections of the first and second arms are substantially co-linear and define a center axis of the apparatus. A second section extends at an angle from the first section, and a third section extends at an angle from the second section. A fourth section extends at a substantially acute angle relative to the third section. The third and fourth sections of each of the first and second arms are substantially co-planar relative to each other, and are substantially non-planar relative to the first sections of the arms. The fourth sections of the first and second arms reside on opposite sides of the center axis, so that the third and fourth sections of the arms can rest on a top surface of the masonry block unit proximate opposed diagonal corners of the core of the masonry block unit and support the mid-section, which resides in substantially diagonal orientation within the masonry block core.

Description

TECHNICAL FIELD AND BACKGROUND OF THE INVENTION[0001]This application claims priority to U.S. Provisional Patent Application No. 60 / 865,927, filed Nov. 15, 2006. The invention of this application relates to a tool for aiding in the positioning of an object. In particular, the invention can be used to maintain the position of a rebar within the core of a masonry block.[0002]It is common in masonry block construction to utilize an elongate steel reinforcing bar, also known as a reinforcement bar or “rebar”, positioned vertically within the cell or core of a concrete block or other masonry block unit to provide added strength and stability to the masonry structure. Generally, it is desirable to have the rebar positioned at or proximate the center of the block core to maximize the stabilizing effect of the rebar. As such, a positioner is often used to maintain the rebar at the desired position within the block core while grout, concrete or other hardening fill material is poured into th...

Benefits of technology

[0016]According to another preferred embodiment of the invention, the mid-section is comprised of a substantially circular loop defining an enclosed area for receiving the reinforcing bar therein.

[0017]According to another preferred embodiment of the invention, a rebar positioning apparatus includes a mid-section defining at least one substantially confined area for receiving the reinforcing bar therein, and first and second opposed arms extending outward from the midsection. Each of the arms includes a first section extending outward from substantially opposite ends of the mid-section, and the first sections of the first and second arms are substantially co-linear and define a center axis of the apparatus. A second section extends at an angle

Problems solved by technology

Therefore, positioners must rely on the next masonry block being positioned on top of it to maintain its proper position, and the positioners are easily disturbed by movement of the block lying on top of it.

If the rebars are not maintained in their proper position, the strength and stability of the masonry structure is compromised.
