Benefits of technology

[0008]The present invention generally relates to a positioner for maintaining a reinforcing rod in a desired position within a void defined by one or more sidewalls of a building unit. Advantageously, in one embodiment, the positioner includes a single piece of spring wire that defines a centrally-located slot portion and first and second support portions extending from the slot portion. The support portions are configured to enga

Problems solved by technology

Although concrete possesses very high compressive strength, the tensile strength of concrete is significantly lower.
This is because rods that are not centered will be closer to one or more of the sidewalls of the void than the other sidewalls, and the grout will not evenly surround the rod within the void.
Manually positioning the rods within the voids, and then maintaining the correct position as construction proceeds, is difficult, if not impo

DETAILED DESCRIPTION OF THE DRAWINGS

[0024]The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the inventions are shown. Indeed, these inventions may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.

[0025]The present invention generally relates to a positioner for maintaining a reinforcing rod in a certain location within a void of a building unit. As described further below, the positioner is configured to be attached to a reinforcing rod before the rod and attached positioner are inserted into the void. First and second support portions of the positioner are configured to engage the sidewalls of the void, holding the reinforcing rod within the void.

Abstract

A positioner is provided for maintaining a reinforcing rod in a certain position within a void of a building unit. The positioner is sized and shaped to be attached to a reinforcing rod before the rod is inserted into the void of one or more concrete blocks or other building units. The positioner has a slot portion that fits onto the rod as well as two biased support portions that extend from the slot portion to engage the rod in a clip-like manner. The support portions are designed to engage the sidewalls of the void and may be compressible towards the rod while maintaining engagement with the rod to allow the rod and positioner to be inserted into voids that have narrower widths due to excess grout or other restrictions within the void.

Description

FIELD OF THE INVENTION[0001]The present invention relates to reinforcing masonry construction and, more specifically, positioning reinforcing rods within voids formed in masonry units.BACKGROUND OF THE INVENTION[0002]Concrete is a material that is commonly used in construction. For example, Concrete Masonry Units (CMUs), such as blocks of cinder concrete (cinder blocks), ordinary concrete, or hollow tile are often used to construct walls or other structural elements of a building. Although concrete possesses very high compressive strength, the tensile strength of concrete is significantly lower. As a result, reinforcing rods or bars, also known as rebar, are frequently used to strengthen masonry construction against tensile forces.[0003]In order to allow for the reinforcement of the concrete, CMUs are often formed with voids. Typically, a reinforcing rod is placed into one of the voids, such as a void that is in a location within the structure that will experience greater tensile st...
