DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS
FIG. 1 illustrates a perspective view of a concrete element fabrication system 100 used in accordance with an embodiment of the present technology. In the embodiment shown in FIG. 1, the concrete element fabrication system 100 includes a reinforcing guide 101 and a mold 103. The reinforcing guide 101 includes a guide 102 and brackets 104. Each bracket 104 includes a sleeve 106 and a threaded bolt 108. Each sleeve 106 is attached to the guide 102. Each sleeve 106 has an opening 110 therethrough configured to receive a reinforced bar 112. Each sleeve 106 has a hole therein (not shown) configured to receive a threaded bolt 108.
In operation, a reinforcing guide 101 such as the one depicted in FIG. 1, for example, can be constructed by securing a reinforced bar 112 to a guide 102 with brackets 104 as follows. First, a reinforced bar 112 can be passed through the opening 110 of a sleeve 106 and positioned as desired. Then, a threaded bolt 108 can be screwed through a hole in the sleeve 106 by rotating the bolt 108 in a direction a, such that the threaded end (not shown) of the bolt 108 passes through the hole in the sleeve 106. The threaded bolt 108 can be screwed through the hole until it contacts the reinforced bar 112, thereby securing the reinforced bar 112 between the bolt 108 and the sleeve 106.
Likewise, a reinforcing guide 101 such as the one depicted in FIG. 1, can be de-constructed and/or re-configured by unsecuring a reinforced bar 112 from a guide 102. For example, in the embodiment shown in FIG. 1, the reinforced bar 112 can be unsecured from the guide 102 by rotating the bolt 108 in a direction opposite to direction a, thereby unscrewing the bolt 108 from the hole in the sleeve 106. Once the bolt is sufficiently unscrewed from the hole in the sleeve 106, such that the reinforced bar 112 is no longer secured, the reinforced bar 112 can be repositioned or removed from the opening 110 of the sleeve 106.
After a first bracket 104 is used to secure a first reinforced bar 112 to a guide 102, a second bracket 104 can be used to secure a second reinforced bar 112 to the guide 102, and so on, until each bracket 104 that is attached to the guide 102 is being used to secure a reinforced bar 112 to the guide 102.
After a first guide 102 is secured to a reinforced bar 112, another guide 102 can be secured to the reinforced bar 112, and so on, until the desired number of guides 102 are secured to the reinforced bar 112.
Once a reinforcing guide 101 is constructed, it can be placed in a mold 103. The mold 103 can then be filled with mixed concrete. After the concrete sets, the mold 103 can be removed and a concrete element that contains a reinforcing guide can remain.
In the embodiment shown in FIG. 1, three guides 102 are shown secured to four reinforced bars 112. However, in other embodiments, the number and spacing of guides and reinforced bars can vary depending on the design requirements of the reinforcing guide and/or local building codes.
In the embodiment shown in FIG. 1, the guide 102 is made of reinforced bar. In other embodiments, a guide may not be made of reinforced bar. For example, in other embodiments, a guide can be made of any material that is sufficiently strong and durable to be used in a reinforcing guide.
In the embodiment shown in FIG. 1, the guide 102 is circular in shape. In other embodiments, a guide may not be circular. For example, in other embodiments, a guide can be square, triangular, rectangular, trapezoidal, or any other type of shape. For example, in other embodiments, a guide can be a straight element or an element with any number of bends or curves. For example, in other embodiments, the shape of the guide can vary depending on the design requirements of the reinforcing guide.
In the embodiment shown in FIG. 1, the guide 102 is sized to be placed within a tube-shaped mold 103. In one embodiment, a guide may be sized to be placed in a tube-shaped mold that has a diameter of ten inches. In another embodiment, a guide may be sized to be placed in a tube-shaped mold that has a diameter of twelve inches. In other embodiments, a guide may be sized to be placed in a tube-shaped mold that has a different diameter. For example, in other embodiments, the size of the guide can vary depending on the design requirements of the reinforcing guide and/or local building codes that govern minimum concrete fill space.
In the embodiment shown in FIG. 1, there are four brackets 104 attached to each guide 102. In other embodiments, there may not be four brackets attached to each guide. For example, in other embodiments, a guide can have 2, 3, 5, 6, 7, 8 or any other number of brackets attached thereto. For example, in other embodiments, the number of brackets attached to a guide can vary depending on the design requirements of the reinforcing guide.
In the embodiment shown in FIG. 1, the brackets 104 are spaced equidistant from each other around the inner edge of the guide 112. In other embodiments, the brackets 104 may not be spaced equidistant from each other around the inner edge of the guide 112. For example, in other embodiments, the spacing of brackets and/or the placement of brackets on the inner or outer edge of a guide may vary depending on the design requirements of the reinforcing guide.
In the embodiment shown in FIG. 1, each bracket 104 is configured to accommodate a reinforced bar. In one embodiment, each bracket may be configured to accommodate a reinforced bar that is: a 1/2 inch in diameter (such as #4 rebar, for example), 5/8 of an inch in diameter (such as #5 rebar, for example), and/or 3/4 of an inch in diameter (such as #6 rebar, for example). In other embodiments, brackets may be configured to accommodate reinforced bars of different sizes.
In the embodiment shown in FIG. 1, each bracket includes a sleeve 106 and a threaded bolt 108. In other embodiments, a bracket can comprise a c-clamp that is configured to secure a reinforced bar between a threaded element and a side of the c-clamp. In other embodiments, a bracket can comprise a tension sleeve with a perforation that runs the length of the tension sleeve, and the bracket can be configured such that a reinforced bar can be secured to a guide by pressing the reinforced bar through the perforation in the tension sleeve.
In the embodiment shown in FIG. 1, each bracket 104 is welded to the guide 102. In other embodiments, brackets may not be welded to a guide. For example, in other embodiments, brackets can be clipped onto a guide using a tension sleeve with a perforation. In such embodiments, the tension sleeve can be pressed onto the guide such that the bracket is secured onto the guide after the guide passes through the perforation. For example, in other embodiments, the guide and brackets can be a single element. For example, in such embodiments, the guide and brackets can be cast as a single piece.
In the embodiment shown in FIG. 1, the mold 103 is tube-shaped. In other embodiments, a mold may not be tube-shaped. For example, in other embodiments, a mold can be square, triangular, rectangular, trapezoidal, or any other type of shape. For example, in other embodiments, the shape of the mold can vary depending on the design requirements of the concrete element.
In the embodiment shown in FIG. 1, the mold 103 is made of cardboard. In other embodiments, a mold may not be made of cardboard. For example, in other embodiments, a mold can be made of wood and/or other materials. For example, in other embodiments, the material the mold is made of can vary depending on the design requirements of the concrete element.
A tube-shaped mold made of cardboard, such as the one described in connection with FIG. 1, for example, can be used in construction to create columns that are known as footings. Footings can require reinforcing guides, such as those described in connection with FIG. 1, for example. Footings can vary in size and structural requirements and so can the design requirements of reinforcing guides used in their fabrication.
As noted above, alternative embodiments may vary depending on the design requirements of a reinforcing guide and/or a concrete element. Some examples of items that can influence the design requirements of a reinforcing guide and/or a concrete element include: the type of structure that is being fabricated, the size, weight and shape of the structure, and the bearing capacity of the soil upon which the structure will rest.
