Description

BACKGROUND

The current process for laying slabs of concrete can be time-consuming, expensive, and labor-intensive. Laborers must pour concrete into their designated beds, wait for the concrete to set, and then manually create spaces in the concrete through which rebar dowels can be installed. To do this, workers may use large power tools to drill a series of holes into the concrete slab, and then install each rebar dowel. The entire process must be repeated approximately twelve inches on center with each concrete slab that is created. While such use of power tools is effective, it is also time-consuming, and often results in inconsistent quality.

Consequently, a need exists for construction workers to quickly and easily install rebar components into freshly-applied concrete. A simpler, more consistent and time-efficient solution is necessary that would provide construction workers with an efficient tool for connecting slabs of concrete, such as for a roadway. The proposed invention allows for a series of evenly-spaced rebar sleeve devices that are installed before concrete is poured into its corresponding concrete bed. The concrete forms around the rebar sleeve device and sets, creating a series of deep holes into which rebar dowels are inserted. Construction workers may then use this product to connect concrete slabs for roadway construction or other similar projects.

SUMMARY

The following presents a simplified summary in order to provide a basic understanding of some aspects of the disclosed innovation. This summary is not an extensive overview, and it is not intended to identify key/critical elements or to delineate the scope thereof. Its sole purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.

The subject matter disclosed and claimed herein, in one aspect thereof, comprises a rebar sleeve device. The rebar sleeve device comprises a tubular unit with an opening at atleast one end thereof for receipt of a rebar dowel. The tubular unit is typically positioned horizontally and can be elevated by a back extension component and a front extension component secured to the base unit. The front extension component comprises an opening through which the rebar dowel is inserted. The opening of the front extension component comprises a protective covering. The protective covering prevents concrete from filling in the opening, but allows for the insertion of a rebar dowel.

Furthermore in the preferred embodiment of the present invention, a connection component is applied to the rebar sleeve device. The connection component is typically used to connect eight rebar sleeve devices together. However, virtually any number of rebar sleeve devices can be used or connected without affecting the overall scope of the invention. This allows for a series of evenly-spaced rebar sleeve devices to be installed before concrete is poured into its corresponding concrete bed.

Further, a form is applied to cover the front extension component of the rebar sleeve devices. Concrete is then poured into the concrete bed and left to set. Once the concrete is set, the form is removed to expose holes in the concrete created by the rebar sleeve devices. Rebar dowels are then inserted into each hole.

To the accomplishment of the foregoing and related ends, certain illustrative aspects of the disclosed innovation are described herein in connection with the following description and the annexed drawings. These aspects are indicative, however, of but a few of the various ways in which the principles disclosed herein can be employed and is intended to include all such aspects and their equivalents.

DETAILED DESCRIPTION

The innovation is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the innovation can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate a description thereof.

Typically, laying slabs of concrete can be time-consuming, expensive, and labor-intensive. Laborers must pour concrete into their designated beds, wait for the concrete to set, and then manually create spaces in the concrete through which rebar dowels can be installed. A rebar sleeve device would allow construction workers to quickly and easily install rebar components into concrete.

Accordingly, the disclosed rebar sleeve system allows for a series of evenly-spaced rebar sleeve devices that are installed before concrete is poured into its corresponding concrete bed. The concrete forms around the rebar sleeve devices and sets, creating a series of holes into which rebar dowels are inserted. Construction workers may use this product to connect concrete slabs for roadway construction or other similar projects.

Referring initially to the drawings, FIG. 1 illustrates a rebar sleeve device 100. The rebar sleeve device 100 comprises a tubular unit 102 with an opening at atleast one end thereof for receipt of a rebar dowel (not shown). A base unit 104 supports the tubular unit 102. The tubular unit 102 is typically positioned horizontally and can be elevated by a back extension component 106 and a front extension component 108 secured to the base unit 104. The front extension component 108 is typically a slab with a rounded top, but does not have to be, and can be any suitable shape. The front extension component 108 also comprises a flange that curves up to secure the rebar sleeve device 100 with existing concrete forms (not shown). However, any amount of material and/or shape or size of the front extension component 108 can be used depending on cost and other building requirements without detracting from the claimed invention.

Furthermore, the front extension component 108 comprises an opening 110 through which the rebar dowel is inserted. The opening 110 is typically a generally, circular hole, however, it can be any suitable shape to accept a rebar dowel. The opening 110 of the front extension component 108 comprises a protective covering 112. The protective covering 112 prevents concrete from filling in the opening 110, but allows for the insertion of a rebar dowel. Specifically, the protective covering 112 is scored and bends inward to accommodate an inserted rebar dowel. The protective covering 112 is typically plastic but can be any suitable material for preventing concrete from filling in the opening 110, but also allowing the insertion of a rebar dowel.

Furthermore, the tubular unit is comprised of polymer material and/or metal, but can be comprised of any suitable material.

In more detail, FIG. 2 illustrates a rebar sleeve system 200 wherein a form 202 is applied to the rebar sleeve devices 100. The form 202 is typically metal or wood and is applied to cover the front extension component of the rebar sleeve devices 100. Typically, the form 202 is ten feet in length, but can be any suitable length needed. In use, the rebar sleeve devices 100 are positioned in a concrete bed and the form 202 is applied to cover the front extension component of each rebar sleeve device 100. Concrete is then poured into the bed and left to set. Once the concrete is set, the form 202 is removed to expose holes in the concrete created by the rebar sleeve devices 100. Rebar dowels are then inserted into each hole.

FIG. 3 illustrates the rebar sleeve system 200 wherein eight rebar sleeve devices 100 are connected together via a connection component 302. The connection component 302 secures the rebar sleeve devices 100 together as one unit. The rebar sleeve system 200 can then be placed in a concrete bed. This allows for a series of generally, evenly-spaced rebar sleeve devices 100 to be installed before concrete is poured into its corresponding bed. The connection component 302 is typically plastic, but can be comprised of any suitable material. The connection component 302 is typically formed integral with the rebar sleeve devices 100 as a one-piece unit, but can also be manufactured as a separate component and secured to the rebar sleeve devices 100 at a later time.

The rebar sleeve devices 100 comprise a tubular unit 102 with an opening at atleast one end thereof for receipt of a rebar dowel (not shown). The tubular unit 102 is typically positioned horizontally and can be elevated by a back extension component 106 and a front extension component 108 secured to a base unit 104. The front extension component 108 also comprises an opening 110 through which the rebar dowel is inserted. The opening 110 of the front extension component 108 comprises a protective covering 112. The protective covering 112 prevents concrete from filling in the opening 110, but allows for the insertion of a rebar dowel. Specifically, the protective covering 112 is scored and bends inward to accommodate an inserted rebar dowel.

Furthermore, FIGS. 4-6 illustrate the rebar sleeve system 200 in use. As shown in FIG. 4, the rebar sleeve devices 100 are secured together via a connection component (not shown) and positioned in a concrete bed 404. This allows for a series of generally, evenly-spaced rebar sleeve devices 100 to be installed before concrete 402 is poured into the concrete bed 404. Form 202 is applied to cover the front extension component of each rebar sleeve device 100. Concrete 402 is then poured into the bed 404 and left to set. As shown in FIG. 5, concrete forms around the rebar sleeve devices 100 creating a series of holes 502. Once the concrete 402 is set, the form is removed to expose the holes 502 in the concrete 402 created by the rebar sleeve devices 100. As shown in FIG. 6, rebar dowels 602 are then inserted into each hole 502 of the hardened concrete 402. Construction workers can then use this product to connect concrete slabs for roadway construction or other similar projects.

FIGS. 7-8 illustrate methodologies of installing rebar dowels into concrete, according to various aspects of the innovation. While, for purposes of simplicity of explanation, the one or more methodologies shown herein (e.g., in the form of a flow chart or flow diagram) are shown and described as a series of acts, it is to be understood and appreciated that the subject innovation is not limited by the order of acts, as some acts may, in accordance therewith, occur in a different order and/or concurrently with other acts from that shown and described herein.
