- The present invention relates generally to devices utilized in the construction field and more particularly to an apparatus or highchair for supporting a reinforcing element in freshly poured concrete.
- Reinforced concrete construction is well known in the art. Applications include but are not limited to sidewalks, floors, roadways, walls of buildings and the like. One method of concrete reinforcement involves the utilization of metal bars or rods known as rebar. Another involves the use of concrete mesh typically made from metal wire.
- Specifically, the reinforcing element is positioned in the concrete in one or more layers between the upper and lower surfaces. In order to achieve this end an apparatus or device, commonly known as a spacer, bolster or chair is utilized to hold the reinforcement element in the desired position between the upper and lower surfaces of the concrete to be poured. More specifically, the workers prepare the lower surface of the form structure. The spacers, chairs or bolsters are then positioned on the prepared surface for supporting the reinforcement element in a plane generally parallel to the prepared surface but vertically spaced from that surface. The reinforcement element is then positioned on the spacer, bolster or chair. The concrete is then poured into the form so as to fully surround the reinforcement element.
- The present invention relates to a new and improved apparatus for supporting a reinforcement element in freshly poured concrete.
- In accordance with the purposes of the present invention as described herein, an apparatus is provided for supporting a reinforcing element in freshly poured concrete. That apparatus comprises a body including a reinforcing bar bearing indentation and a concrete mesh bearing notch. The concrete mesh bearing notch includes three concrete mesh engaging edges. The concrete mesh bearing notch has a width of between about 2/8 to about 5/16 inch and a depth of between about 2/8 to about 5/16 inch. Further the concrete mesh bearing notch has a narrow neck.

- In the following description there is shown and described a preferred embodiment of this invention, simply by way of illustration of one of the modes best suited to carry out the invention. As it will be realized, the invention is capable of other different embodiments and its several details are capable of modification in various, obvious aspects all without departing from the invention. Accordingly, the drawings and descriptions will be regarded as illustrative in nature and not as restrictive.
- The accompanying drawing incorporated in and forming a part of this specification, illustrates several aspects of the present invention, and together with the description serves to explain certain principles of the invention. In the drawing:
-
FIG. 1 is a perspective view of the apparatus of the present invention; -
FIG. 2 is a perspective view illustrating how multiple high chairs of the type illustrated inFIG. 1 are utilized to support rebar in a concrete form; -
FIG. 3 is a perspective view illustrating how the apparatus ofFIG. 1 may be used to support concrete mesh in a form; and -
FIG. 4 is a detailed side elevational view illustrating how the highchairs may be “stacked” to support rebar and mesh in a concrete form. - Reference will now be made in detail to the present preferred embodiment of the invention, an example of which is illustrated in the accompanying drawing.
- Reference is now made to
FIG. 1 illustrating the apparatus orhighchair 10 of the present invention. The apparatus includes abody 12 constructed of a non-biodegradable material. The non-biodegradable material is impervious to water and is preferably both shatter resistant and sag resistant within a temperature range between 220° and −40° F. Examples of such material include ABS plastic, polycarbonates, polybutyleneterephthalates, polyphenylene oxides and any mixtures thereof. Advantageously, utilization of any of these resins allows the simple and relatively inexpensive injection molding of theapparatus 10 of the present invention in one strong, lightweight piece. - The
body 10 includes at least one reinforcingbar bearing indentation 14 and at least one concretemesh bearing notch 16. Each reinforcingbar bearing indentation 14 is specifically sized and shaped to receive a reinforcing bar such as steel rebar which may be utilized in various diameters typically of one-half inch or more to reinforce concrete. In the illustrated embodiment the reinforcingbar bearing indentation 14 has a radius of curvature of between about 150 and about 195 inches. Thus, theindentation 14 is deepest in the middle so that the rebar, which is round in cross section, tends to rest in the middle of each indentation over the center of theapparatus 10. In this way the rebar is held in position on theapparatus 10 with the weight over the center of the apparatus so as to avoid tipping of the apparatus. - Each concrete
mesh bearing notch 16 is sized and shaped to positively engage and hold a concrete mesh reinforcing element. More specifically, eachnotch 16 has a width and depth of between about 2/8 inch and about 5/16 inch. As illustrated, thenotch 16 may be provided with a relatively wide width at the bottom and a partially closed, narrower width orneck 17 at the top. As a consequence, thenotch 16 has a tendency to positively engage and hold concrete mesh in a manner described in greater detail below. - More specifically describing the invention, the
body 12 may include eight walls. Thefirst wall 18 is opposed by thesecond wall 20. Thethird wall 22 is opposed by thefourth wall 24. Thefifth wall 26 is opposed by thesixth wall 28. Finally, theseventh wall 30 is opposed by theeighth wall 32. Each of the opposing first andsecond walls bar bearing indentation 14. Similarly, each of the opposing fifth andsixth walls bar bearing indentation 14. Theindentations 14 in the first andsecond walls sixth walls - In the illustrated embodiment, the
indentations 14 in the first andsecond walls indentations 14 in the fifth andsixth walls indentations 14 are provided in the opposing walls in order to allow theapparatus 10 to support a long piece of rebar extending past each opposing wall. - As should also be appreciated, each opposing third and
fourth wall mesh bearing notch 16. Similarly, each opposing seventh andeighth wall mesh bearing notch 16. Thenotches 16 in the third andfourth walls notches 16 in the seventh andeighth walls - As further illustrated, an
annular base 36 interconnects all of thewalls apparatus 10 and to provide a more stable base to hold theapparatus 10 in an upright position in the concrete form. - As further illustrated, each of the primary or
wider walls indentations 14 also includecutout openings 34. These openings serve multiple functions. First, they reduce the cost of manufacture by reducing the material needed to produce eachapparatus 10. Additionally, they allow apparatus or chairs 10 of different sizes to be stacked in a form to hold reinforcing elements at different heights during a concrete pour in a manner that will be described in greater detail below. - Still further it should also be appreciated that the
body 12 tapers outwardly from the top to the bottom. This allows a number of thehighchairs 10 to be nested together for high density shipping in a smaller container. - Use of the
apparatus 10 of the present invention will now be described with reference toFIGS. 2-5 . As illustrated inFIG. 2 , theapparatus 10 is placed at the bottom B or on the floor of the form F. Advantageously, thebase 36 provides a wide stance relative to the tapered top of theapparatus 10 so as to resist tipping. A length of steel reinforcing bar R is supported on theapparatus 10 with the bar resting in the bottom of theindentations 14 in the opposing first andsecond walls highchairs 10 may be spaced at desired intervals to support a length of reinforcing bar R in the form F prior to the pouring of concrete. - As illustrated in
FIG. 3 , theapparatus 10 is equally adapted for supporting concrete mesh M. More specifically, theapparatus 10 is positioned with theannular base 36 engaging the bottom B of the form F. The concrete mesh M is then placed on theapparatus 10 so that the individual wire strands S are received in at least one and more typically each of the fournotches 16. As should be appreciated, thenotches 16 are each sized so that the edges of thenotches 16 positively engage and hold one of the strands S at three points along the bottom and sides of the notch. Further, note how thenarrow neck 17 of eachnotch 16 closes over the strand S to positively engage and hold the strand in position. Once again, one uses as many of thehighchairs 10 as necessary to support the concrete mesh M at spaced locations so that the mesh is held at the desired height in the form F prior to the pouring of concrete. - Reference is now made to
FIG. 4 illustrating howhighchairs 10 of the present invention may be made of varying heights and utilized together to hold reinforcing elements in different planes at different vertical heights in a form F. As illustrated, a first relatively short apparatus orhighchair 10 is positioned on the bottom B of the form F. A second, taller apparatus orhighchair 10′ is also positioned with a base 36′ engaging the bottom B of the form F. If desired, thesecond highchair 10′ may be positioned nesting over theshorter highchair 10 as illustrated. Alternatively, they may be provided at completely different positions in the form F. - In the illustration, reinforcing bar R is supported on the shorter apparatus or
highchair 10 while concrete mesh M is supported at a higher vertical height in a separate plane by the taller apparatus orhighchair 10′. Of course, it should be appreciated that thehighchairs - The embodiment was chosen and described to provide the best illustration of the principles of the invention and its practical application to thereby enable one of ordinary skill in the art to utilize the invention in various embodiments and with various modifications as are suited to the particular use contemplated. All such modifications and variations are within the scope of the invention as determined by the appended claims when interpreted in accordance with the breadth to which they are fairly, legally and equitably entitled. The drawings and preferred embodiment do not and are not intended to limit the ordinary meaning of the claims and their fair and broad interpretation in any way.
