DETAILED DESCRIPTION OF DRAWINGS AND SPECIFICATIONS

[0025] For a curb, walk and multi-use forming tool and system

[0026] The tool consists of a bracket, spacer, their components and fasteners. The bracket, FIGS. 1 and 2 is designed to anchor and contain the formboards that establish the limits of the poured material. The bracket is adjustable in width. That is one of the reasons that it is made up of two similar or identical halves, FIGS. 1, 2, 3 and 4. Each half is designed to anchor a formboard or forming material.

[0027] In forming a bracket, the halves overlap each other. By sliding them back and forth, the user can set the desired width and interlock them to form a bracket, using screws or other fasteners.

[0028] The bracket, in an upright position, appears somewhat like an inverted U shape that can straddle the pour area and the formboards and attach thereto. Ground anchorage of the bracket is achieved by metal stakes, re-bar, or spikes that thread through vertically aligned guide holes or enclosures that are a part of the bracket and are described as follows:

[0029] Each bracket half has a minimum of two guides for the metal anchors. The horizontal part of the top contains a round hole for the anchor to thread through. The vertical part has a guide hole, or formed surround that is aligned vertically with the top hole to provide a straight and clear vertical path for the round metal anchor which is to be driven into the ground. Ground anchorage can also be accomplished with wood or similar stakes that are fastened to the main body and/or fins of the bracket by the use of screws, nails or similar attachments.

[0030] Where it is desired to form edging or curbs to existing pours such as walkways, patios, etc. or to form pours for new sidewalks FIG. 5, drain troughs, pads or pours that are wider than the bracket can straddle, bracket halves can be connected by rigid ties.

[0031] Each spacer is made up of two half spacers and their fasteners FIGS. 6, 7 and 8. The spacer, FIG. 8, is designed to hold the formboards firmly against the bracket. It is placed in the pour area to maintain the desired width of pour. When the pour is still slightly fluid, but firm enough to hold the formboards in place, it is removed. The spacer can also be used in the pour area between the formboard and existing pours FIG. 5. Since the width of the spacer is adjustable by overlapping and interlocking spacer halves at the desired width, different thickness formboards or irregular existing edges of a pour can be accommodated and compensated for.

[0032] The fasteners, which join the bracket halves together and the spacer halves together, can be of several forms: slots, slotted holes, or a combination thereof. Screws, bolts, nuts and wingnuts may be used. With certain manufacturing processes, snap-on or cast interlocks (not shown) are conceivable and feasible.

[0033] The corners and bends in brackets and spacers will, where practical, be softened by radii to facilitate ease and safety of handling thereof. In the brackets and spacers it is desired as an option, but not shown for clarity, to provide markings along the horizontal slots and slotted holes. This would simplify setting the widths desired for a specific pour.

Manufacturing:

[0034] Brackets and spacers will be manufactured of the thickness, and strength appropriate to their usage.

[0035] The prototype made and illustrated hereinsee FIGS. 1, 2, 3, 4, 5, 6, 7 and 8, was cut from sheet steel by water jet and shaped by machine shop bending, and would be appropriate for many uses such as forming versions of items 1, 2, 3, 4, and 5 listed in the summary. Large quantities can be made as described above or by using laser and plasma cutters, stamping machines, molds and other means, including but not limited to, forging and casting.

[0036] Brackets and spacers for heavy duty applications will likely require the use of, but not be limited to, the more stringent processes listed above.

[0037] While the materials for the brackets and spacers will likely be metal, other materials such as, but not limited to, plastics and composits may be used.

Using the Kit: An Example

[0038] The kit consisting of approximately 5-6 brackets and 5-6 spacers can be used as follows: the line that either an outer or inner form board is to follow on the ground is determined by string lines, chalk lines, or other means. Brackets are offset from the line a distance equal to the form board thickness and then placed approximately 2-3 ft apart. Anchorage thereof is set or partially set for at least one side of the brackets. A form board is then placed along the line. Brackets are checked for accuracy of alignment, then attached to the form board. Then the anchorage of both sides of the bracket is done and the other form board is placed and fastened to the other side of the brackets.

[0039] At this stage reinforcing rods can be placed as needed and supported by wire suspension using the holes in the brackets. Final inspection is in order to see that all ground anchorage is firmly in place and the system for pouring is intact.

[0040] The spacers are preset in width to conform to the pour width which is determined by the bracket settings and the form board thickness. The spacers are then placed in the pour area. The distance between spacers is determined by the need to hold the form boards firmly in place.

[0041] At this point off the shelf pour material can be mixed and poured for small projects. While the material is still pliable, the spacers are removed, the material set, forms removed, and the process repeated as desired.

[0042] For small projects, especially pours where curves are involved, it may work better for the form board to be pre-attached to one side of the brackets, set on line and anchored.

Features:

[0043] 1. Brackets and spacers, each can be fixed width or set by the user to different widths [0044] 2. Provides support for reinforcing rods by suspension with wires from bracket slots or holes. [0045] 3. Brackets and form boards can be partially pre-assembled. This could be especially useful on curved forms if form boards are attached to one side of brackets first, then set in place. [0046] 4. Brackets and spacers and their component pieces can be manufactured and sold off the shelf [0047] 5. Kits can be assembled, packaged, and marketed. A kit would include enough brackets and spacers that, along with form boards, the user could form and pour an 8 ft to 10 ft section of pour at a time. The kit and form boards can then be removed, re-set, and the process repeated as desired.

Flexibility:

[0048] 1. Variable width settings for the brackets and spacers. [0049] 2. A number of applications and usage. [0050] 3. Means of ground anchorage can be by steel rods, re-bar, spikes, metal or wood stakes. [0051] 4. Readily applicable to forming straight, multi-curved, and arc shaped pourings. [0052] 5. The tool and its components are re-usable.

Simplicity:

[0053] 1. Ease of fabrication [0054] 2. Ease of handling and usage [0055] 3. Ease of dismantling and re-use [0056] 4. Ease of storage [0057] 5. Low tech
