Stackable rebar support chair

Abstract

A stackable rebar support chair having a support chair and a support plate detachable to each other. The support chair includes a base having multiple upstanding posts and downwardly extending legs designed to suspend the base above surface. The base can include multiple holes to permit the free flow of concrete around the support chair. Multiple centering supports can connect to and extend between each of the upstanding posts and an upper surface of the base to provide support to the posts and to permit gravity to assist positioning the supported rebar to a generally central position on the base. The base can include ribs extending from its lower surface to provide support to the base from the weight of the rebar. The support plate can include multiple generally upright pegs having recesses to receive the legs.

Description

FIELD OF THE INVENTION[0001]The present invention relates generally to an apparatus for positioning and supporting rebar and other reinforcement devices a distance above a surface. More specifically, the invention relates to a stackable rebar support chair having centering supports designed to automatically position the rebar on the support chair and to support upstanding posts used to stack multiple support chairs.BACKGROUND OF THE INVENTION[0002]The use of various rebar support chair devices is known in the prior art. However, all of these devices fail to provide a stackable rebar support chair having centering supports designed to automatically position the rebar on the support chair. They also lack centering supports that are designed to support upstanding posts that are used to stack multiple support chairs on top of each other.BRIEF SUMMARY OF THE INVENTION[0003]The invention in particular embodiments has base having a number of legs extending downwardly from a lower surface a...

AI Technical Summary

Benefits of technology

[0004]In one embodiment of the invention there is at least one centering support connected to and extending between each of the upstanding posts and the upper surface of the base. Each of the centering supports is designed to permit gravity to assist the supported rebar to a generally central position on the base, thereby facilitating proper weight distribution and alignment. Additionally, the centering supports reinforce the upstanding posts when the rebar support chairs are stacked on top of each other. In another embodiment of the invention, there are multiple centering supports connected to and extending between each of the upstanding posts and the base.

[0005]In another example embodiment of the invention, the base can include at least one hole extending through it to permit the free flow of concrete, cement or any other type of construction material. In another embodiment of the invention there are multiple holes extending through the base such that at least a pair of cross supports is formed extending between the upstanding posts and legs. In this embodiment of the invention, centering supports can be attached to and can extend between the upstanding posts and the cross supports. Additionally, ribs may be positioned on a lower surface of the base, and / or base and cross supports to provide additional structural rigidity.

Problems solved by technology

However, all of these devices fail to provide a stackable rebar support chair having centering supports designed to automatically position the rebar on the support chair.

They also lack centering supports that are designed to support upstanding posts that are used to stack multiple support chairs on top of each other.
