Description

BACKGROUND

The present invention relates generally to the formation of pre-cast panels, and more particularly to elongate bodies for providing architectural and structural features in pre-cast panels.

Pre-cast construction of concrete wall panels for tilt-up and other types of construction is well known in the art. In the tilt-up approach, forms, also known as form liners, are placed on a flat casting surface in the shape and dimension of the desired panel and filled with concrete. When the concrete cures, the forms may be removed, and the panel tilted up into a preferred, typically vertical, orientation, where it can be joined to structural frames or other panels. The panels may have architectural features such as reveal bands or structural features formed therein by providing an elongate body that is attached to the casting surface inside the form.

The present inventor has recognized a need for elongate bodies that may be used with a variety of pre-cast systems to provide panels having architectural or structural features. An additional need exists for such bodies that can be easily attached, removed, and reused.

SUMMARY

This need is met by the present invention that provides elongate bodies for use with precast panel forming systems. As used herein, pre-cast panel forming systems include any panel forming system that allows panels to be formed from a cast material that upon curing hardens, thereby allowing the panel to be subsequently placed in a desired location within a building structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention is directed toward elongate bodies for use with pre-cast panel forming systems. The elongate bodies may be used to provide architectural or structural features in pre-cast panels.

Referring to FIGS. 1A-1D and 2A-2C, several embodiments of an elongate body 10 are illustrated in cross-section in an engaged state. The body 10 has a set portion 12, a hinged portion 14, and a hinge 16. The elongate body 10 of the present invention may be manufactured in an extrusion process and, as such, may comprise an extruded cross-section extending along its entire length. The elongate body may be formed from any plastic material but is preferably formed from extricable plastic materials because the design of the present invention is well-suited for manufacture by an extrusion process. Preferred materials include polyvinyl chloride (PVC), low or high-density polyethylene or polypropylene, acrylics, polycarbonates, and thermoplastic elastomers. As will be appreciated by those familiar with the art of extrusion, an extruded member defines a substantially uniform extruded cross-section that extends along substantially the entire length of the member.

Referring to FIGS. 1A-1D, several embodiments of the elongate body 10 are illustrated. The set portion 12 has a first member 18, and first member 18 defines a base plane 20. At least a portion of the first member 18 is configured to engage a panel forming surface. The hinge 16 couples set portion 12 and hinged portion 14. The set portion 12 and hinged portion 14 are configured to define an engagement 24, and the hinged portion 14 is movable about the hinge 16 to an engaged state and disengaged state of the engagement. The set portion 12 may define a first beveled edge 22 extending away from the base plane 20, and the first beveled edge 22 may intersect the base plane 20.

The hinged portion 14 may define a face plane 28 opposite the base plane 20, and the first beveled edge 22 defined by the set portion may extend away from the base plane 20 toward the face plane 28. The hinged portion 14 may have a second beveled edge 34 extending away from the base plane 20 toward the face plane 28. The first and second beveled edges 22, 34 may be inwardly canted edges as shown in FIGS. 1A-1D, and the first and second beveled edges 22, 34 may intersect the base plane 20.

The hinged portion 14 may have a second member 26 that extends along the face plane 20. The set portion 12 may have a first sidewall 30 extending away from said first member 18. The first beveled edge 22 may extend to a portion of the first sidewall 30 displaced from the base plane 20.

The hinge 16 may be formed in any suitable manner. For example, the hinge 16 may comprise relatively pliant portions of the extruded cross section and the set portion 12 and hinged portion 14 may define relatively rigid portions of the cross section. In this manner, hinge 16 comprises a living hinge formed with the set portion 12 and the hinged portion 14. For the purposes of defining and describing the present invention, it is noted that a living hinge may be bent multiple times without breakage or fracture of the hinge material. Living hinges may be formed from soft, flexible thermoplastic elastomers that exhibit high endurance to flexural fatigue. Although the hinge 16 is shown along the second member 26 adjacent to the first sidewall 30, it will be understood by those having skill in the art at that hinge 16 may be formed in any suitable position that allows the hinged portion 14 to be moved into an engaged and disengaged state of the engagement 24. For example, the hinge 16 may be proximate to the face plane 28.

Referring to FIGS. 1A and 1B, the set portion 12 may also have a second sidewall 32 extending away from the first member 18. The second beveled edge 34 may extend to a portion of the second sidewall 32 displaced from the base plane 20. The engagement 24 may have inwardly extending portions and outwardly extending portions, and the inwardly and outwardly extending portions may be formed in a variety of positions. An inwardly extending portion extends generally towards a central axis of elongate body 10, and an outwardly extending portion extends generally away from a central axis of elongate body 10.

For example, as shown in FIG. 1A, the inwardly extending portion 36 of the engagement 24 extends from a portion of the second sidewall 32 of the set portion 12 displaced from the base plane 20, and the inwardly extending portion 36 extends generally towards a central axis of elongate body 10. The outwardly extending portion 38 of the engagement 24 extends from the second member 26 of the hinged portion 14 such that the inwardly extending portion 36 and the outwardly extending portion 38 are capable of being engaged as shown in FIG. 1A. The outwardly extending portion 38 extends generally away from a central axis of elongate body 10. Alternatively, as shown in FIG. 1b, the inwardly extending portion 40 of the engagement 24 extends from a portion of the second beveled edge 34 of the hinged portion 14 displaced from the base plane 20. The outwardly extending portion 42 of the engagement 24 extends from the second sidewall 32 at the set portion 12 such that the inwardly extending portion 40 and the outwardly extending portion 42 are capable of being engaged as shown in FIG. 1B.

Referring to FIGS. 1C and 1D, the hinged portion 14 may also have a second sidewall 33 extending away from the first member 18. The second beveled edge 34 may extend to a portion of the second sidewall 33 displaced from the base plane 20. The engagement 24 may have an inwardly extending portion and an outwardly extending portion, and inwardly and outwardly extending portion may be formed in a variety of positions.

For example, referring to FIG. 1C, the engagement 24 may have an inwardly extending portion 44 extending from a portion of the second sidewall 33 of the hinged portion 14 proximate to the base plane 20. The engagement 24 may have an outwardly extending portion 46 extending from the first member 18 of the set portion 12 such that the inwardly extending portion 44 and the outwardly extending portion 46 are capable of being engaged as shown in FIG. 1C. Alternatively, referring to FIG. 1D, the engagement 24 may have an outwardly extending portion 50 extending from a portion of the second sidewall 33 of the hinged portion 14 proximate to the base plane 20. The engagement 24 may have an inwardly extending portion 48 extending from the first member 18 of the set portion 12 such that the inwardly extending portion 48 and outwardly extending portion 50 are capable of being engaged as shown in FIG. 1D.

Referring again to FIG. 1D, the elongate body 10 may have a fastening area or areas 52 provided in the first member 18. For example, the fastening areas 52 may be grooves formed in the first member 18 in order to allow fasteners such as nails or screws (not shown) to be more easily driven through the first member 18 to secure the elongate body 10 to a panel forming area. It will be understood by those having skill in the art that the fastening areas may be provided in the first member 18 and 18a of the elongate bodies shown in FIGS. 1A-1D and 2A-2C.

Referring to FIG. 3, the elongate body 10 illustrated in FIG. 1A is shown with the engagement 24 in a disengaged state. Thus, the hinged portion 14 is movable about the hinge 16 to an engaged state and disengaged state of the engagement 24. When the engagement 24 is in a disengaged state, the first member 18 may be exposed in order to allow the first member 18 to be fastened to a panel forming surface. Subsequently, the engagement 24 may be engaged in order to allow the elongate body 10 to be used to form architectural features in pre-cast panels. It will be understood that the elongate bodies illustrated in FIGS. 1B-1D may be similarly engaged and disengaged about the engagement 24.

Referring to FIGS. 2A-2C, alternative embodiments of the elongate body 10 are illustrated. The set portion 12 has a first member 18a, and the first member 18a defines a base plane 20. At least a portion of the first member 18a is configured to engage a panel forming surface. The hinge 16 couples the set portion 12 and the hinged portion 14. The set portion 12 and the hinged portion 14 are configured to define an engagement 24, and the hinged portion 14 is movable about the hinge 16 to an engaged and disengaged state of the engagement 24 as described above in conjunction with the embodiments illustrated in FIGS. 1A-1D. The hinged portion 14 may define a first beveled edge 22a that extends away from the base plane 20.

Referring to FIGS. 2A-2B, the hinged portion 14 may further define a first sidewall 31 extending away from the first member 18a. The first beveled edge 22a may extend from the first member 18a of the set portion 12 to a portion of first sidewall 31 of the hinged portion 14 displaced from the base plane 20. The hinge 16 may be located proximate to the first member 18a of the set portion 12. For example, as shown in FIG. 2A, the hinge 16 may be located proximate to the first member 18a of the set portion 12 along the first sidewall 31 of the hinged portion 14. Alternatively, as shown in FIG. 2B, the hinge 16 may be located proximate to the first member 18a of the set portion 12 along the first beveled edge 22a of the hinged portion 14. It will be understood by those having skill in the art that the exact location of the hinge may be changed so long as the engagement 24 may be engaged and disengaged effectively.

The engagement 24 may have an inwardly extending portion and an outwardly extending portion, and inwardly and outwardly extending portion may be formed in a variety of positions. For example, as shown in FIG. 2A, the engagement 24 may have an inwardly extending portion 56 extending from a portion of the first beveled edge 22a of the hinged portion 14 proximate to the base plane 20. The engagement 24 may have an outwardly extending portion 54 extending from the first member 18a of the set portion 12 such that the inwardly extending portion 56 and the outwardly extending portion 54 are capable of being engaged as shown in FIG. 2A. Alternatively, as shown in FIG. 2B, the engagement 24 may have inwardly extending portion 58 extending from a portion of the first sidewall 31 of the hinged portion 14 proximate to the base plane 20. The engagement 24 may have an outwardly extending portion 60 extending from the first member 18a of the set portion 12 such that the inwardly extending portion 58 and the outwardly extending portion 60 are capable of being engaged as shown in FIG. 2B.

Referring to FIG. 2C, the set portion 12 may further define a first sidewall 35 extending away from the first member 18a. The first beveled edge 22a may extend from the first member 18a of the set portion 12 to a portion of first sidewall 35 of the set portion 12 displaced from the base plane 20. The hinge 16 may be located proximate to the first sidewall 35 of the set portion 12. The engagement 24 may have an inwardly extending portion and an outwardly extending portion, and inwardly and outwardly extending portion may be formed in a variety of positions. For example, the engagement 24 may have an inwardly extending portion 62 extending from the first beveled edge 22a of the hinged portion 14 proximate to the base plane 20. The engagement may have an outwardly extending portion 64 extending from the first member 18a of the set portion 12 such that the inwardly extending portion 62 and outwardly extending portion 64 are capable of being engaged as shown in FIG. 2C.

FIG. 4 illustrates an elongate body 10 similar to the embodiments illustrated in FIGS. 1a-1b in a concrete casting operation. The elongate body 10 is secured to the panel forming surface 70. The elongate body 10 may be secured to the panel forming surface 70 through conventional means, such as tape, screws, nails, rivets or a soluble glue (not shown). At least a portion of the first member 18 engages the panel forming surface 70. For example, the elongate body 10 may be opened about the hinge 16 to a disengaged state (not shown) and nailed to the panel forming surface. The engagement 24 is subsequently engaged, and the pre-cast material is poured around at least the elongate body 10 in an uncured state and allowed to cure. Although FIG. 4 illustrates an elongate body similar those in FIGS. 1A-1D, it will be understood by those having skill in the art that the elongate bodies 10 of FIGS. 2A-2C may be similarly utilized.

Referring to FIGS. 1A-1D and 4, the intersection of the beveled edges 22, 34 with the base plane 20 ensures that a generally downward-projecting load provided by the casting material 72 will force the beveled edges 22, 34 to laterally scrape along the panel-forming surface 70, thus minimizing the amount of pre-cast material 72, such as concrete, that can seep in underneath elongate body 10. This seal between the beveled edges 22, 34 and the panel forming surface 70 promotes long-life, reusable elongate bodies, as the opportunity for the formation of cured/hardened casting material on the elongate body surfaces is reduced.

A method of manufacturing pre-cast panels would include configuring an elongate body as described in conjunction with the embodiments herein, placing the elongate body on a panel forming surface, securing the elongate body to the surface through conventional means, such as tape, screws, nails, rivets or a soluble glue, pouring pre-cast material into a panel at least partially defined by the elongate body, curing the poured concrete, and removing the elongate body from the panel forming surface. The elongate body may be secured with the engagement disengaged and the engagement may be subsequently engaged.

Referring to FIG. 5, a portion of a pre-cast panel form 80 having an elongate body 10 placed therein is illustrated. The pre-cast panel form 80 has a length L₁. Elongate body 10 is configured to have a length L₂ that is less than the length L₁ of the pre-cast panel form 80. Thus, the pre-cast panel form 80 and at least one elongate body 10 may form a system for forming pre-cast panels having architectural or structural features to be utilized as described above. It will be understood by those having skill in the art that more than one elongate body 10 may be utilized and that the elongate bodies 10 may be of different lengths. Additionally, the elongate bodies 10 may be configured in any desired configuration.

It will be obvious to those skilled in the art that various changes may be made without departing from the scope of the invention, which is not to be considered limited to what is described in the specification.
