Embodiments relate to the field of construction, in particular, to a brace and kicker apparatus for supporting a form for forming a concrete structure, such as a concrete foundation.
The form holds the concrete (in fluidic state) in place, to allow the concrete to solidify over time to form the desired concrete structure. Typically, because of the weight of the concrete, multiple ones of such brace and kicker arrangements are required to provide the necessary support strength to support the form to keep the form in shape until the concrete solidifies. In general, for an average residential foundation, one such brace and kicker arrangement is required every 2 feet. To provide the necessary support strength, the brace and kicker are typically driven into the ground and nailed to each other using heavy gauge nails. Because of the alignment and precision required, often times at least 2 persons are required to put together each of the multiple arrangements.
After the concrete is poured and settled, the brace and kicker arrangements are broken apart. Some of the wood, like braces 704 will be partially stuck in the solidified concrete, and the protruding portions will have to be broken to remove. Virtually all the removed wood is disposed as waste. Thus, the prior art brace and kicker approach are inefficient and wasteful.
Embodiments will be readily understood by the following detailed description in conjunction with the accompanying drawings. Embodiments are illustrated by way of example and not by way of limitation in the figures of the accompanying drawings.

Embodiments of the brace and kicker apparatus of the present disclosure include means for receiving and holding a brace in support of a form for forming a concrete structure, and means for adjustably mating and supporting the brace with at least three degrees of freedom. In various embodiments, the holding means include complementary secure features to secure the holding means, e.g. to the ground, and holding features that provide a plurality of holding positions for selectively holding the brace in one of a number of holding positions. In various embodiments, the at least three degrees of freedom of the adjustably mating and supporting means include a first angular degree of freedom, a second linear degree of freedom, and a third degree of mating freedom. Further, in various embodiments, the second linear degree of freedom remains available even after choices have been made for the first and third degree of freedom.
In the following detailed description, reference is made to the accompanying drawings which form a part hereof, and in which are shown by way of illustration embodiments in which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the disclosure. Therefore, the following detailed description is not to be taken in a limiting sense, and the scope of embodiments is defined by the appended claims and their equivalents.
Various embodiments will be described with references to the side views and/or top views of various components. The various views are to facilitate understanding, and are not limiting on the invention. The terms “substantially,” “considerably,” “significantly,” “largely,” may be used, and these terms are intended to be synonyms for each other. The description may use the phrases “in an embodiment,” or “in embodiments,” which may each refer to one or more of the same or different embodiments. Furthermore, the terms “comprising,” “including,” “having,” and the like, as used with respect to embodiments, are synonymous
The terms “coupled” and “connected,” along with their derivatives, may be used. It should be understood that these terms are not intended as synonyms for each other. Rather, in particular embodiments, “connected” may be used to indicate that two or more elements are in direct physical or electrical contact with each other. “Coupled” may mean that two or more elements are in direct physical or electrical contact. However, “coupled” may also mean that two or more elements are not in direct contact with each other, but yet still cooperate or interact with each other. For the purpose of this application, wood is not an reusable material for a component or a part, if the component or part is expected to touch concrete in liquid form, as the component or part will be stuck and not removable for reuse after the concrete solidifies.
Various operations may be described as multiple discrete operations in turn, in a manner that may be helpful in understanding embodiments; however, the order of description should not be construed to imply that these operations are order dependent. Also, embodiments may have fewer operations than described. A description of multiple discrete operations should not be construed to imply that all operations are necessary. Also, embodiments may have fewer operations than described. A description of multiple discrete operations should not be construed to imply that all operations are necessary.
For the purposes of the description, a phrase in the form “A/B” means A or B. For the purposes of the description, a phrase in the form “A and/or B” means “(A), (B), or (A and B)”. For the purposes of the description, a phrase in the form “at least one of A, B, and C” means “(A), (B), (C), (A and B), (A and C), (B and C), or (A, B and C)”. For the purposes of the description, a phrase in the form “(A)B” means “(B) or (AB)” that is, A is an optional element.

As illustrated, for the embodiments, brace holder 120 may include base plate 122, and substantially u-shaped end 126 coupled to each other as shown. For the illustrated embodiments, base holder 120 may also include tube 124 coupled to substantially u-shaped end 126 as shown. Base plate 122 may include secure features configured to enable brace holder 120 to be removably secured e.g. to the ground. Tube 124 may include secure features complementary to those of plate 122 to further removably securing brace holder 120, e.g. to the ground. Substantially u-shaped end 126 may be configured to receive and hold the brace, including holding features configured to enable the brace to be removably received and held in any one of a number of holding positions.
Adjustable kicker 110 may include base plate 112, adjustable arm 113 and end piece 118 coupled to each other as shown. Base plate 112 may include secure features configured to removably secure adjustable kicker 110, e.g. to the ground. For the embodiments, adjustable arm 113 may be configured to be pivotally coupled to base plate 112, to allow adjustable arm 113 to move angularly or rotate relative to base plate 112. Further, adjustable arm 113 may be configured to be linearly adjustably coupled to end piece 118, as well as itself is linearly adjustable in length. For the embodiments, adjustable arm 113 may comprise first and second portions of adjustable arm 114a and 114b, and turnbuckle 116, linearly and adjustably coupled to each other. End piece 118 may be linearly adjustably coupled to the turnbuckle 116. End piece 118 may also include mating features configured to provide a number of mating positions for mating with the brace in a selected one of the mating positions. Adjustable arm 113 may be linearly adjustable even after base plate 112 has been secured, e.g. to the ground, and end piece 118 has been mated with the brace. Adjustable arm 114a and 114b may be configured to provide coarse adjustment, while turnbuckle 116 may be configured to provide finer adjustment.
In various embodiments, the various parts may be constituted with metallic material to provide strength to support the form, as well as enabling the brace and kicker arrangement to be reusable, reducing the amount of wood product waste. In alternate embodiments, other materials with similar tensile strength and reusable characteristics may be used instead, in part or in whole.
The dimensions of the various elements are application dependable, that is, dependent on the size of the brace and form the apparatus is designed to support. In various embodiments, the brace holder occupies an area of approximately 12″ by 8″, whereas the adjustable kicker is approximately 4 ft in length.
As will be appreciated by those of ordinary skill in the art, the various features of the brace and kicker apparatus of the present disclosure collectively enable a brace and kicker arrangement to be formed efficiently, potentially by a single person, resulting in substantial saving in labor. Equally significant, after the desired concrete structure has been formed, the brace and kicker arrangement can be disassembled relatively easily by one person, as unlike the prior art approach where some of the wood stakes will be partially trapped in the solidified concrete requiring the wood stakes to be broken to remove the protruding portions, the brace and kicker apparatus of various embodiments of the present disclosure may be quickly disassembled without any components trapped in the solidified concrete. Accordingly, embodiments of the apparatus may be reused to support another brace to support another form for forming another concrete structure.

As illustrated, base plate 122 may include a plurality of openings 202 configured to enable the base plate to be secured to e.g. the ground, using e.g. soil nails, earth anchors or concrete stakes. A soil nail is a standard concrete stake with a nut or a piece of steel welded to the top to form a large nail-like structure that can be driven into the soil to serve a similar function as a standard nail driven into a piece of wood. Tube 124 may have an hollow interior to provide complementary support to securing the brace holder to e.g. the ground, using e.g. a soil nail, an earth anchor or a concrete stake. In various embodiments, as illustrated, tube 124 and base plate 122 may jointly define an angle (in the side view plane) in the range of 95 degrees to 105 degrees. (This angle of the tube may provide strength to enable the brace to be cantilevered over a trench.) In various embodiments, tube 124 and base plate 122 may define an angle (in the side view plane) of about 100 degrees. In alternate embodiments, base plate 122 may include a plurality of tubes 124, e.g. two symmetrically disposed at the inside or outside surfaces of the side arms of base plate 122.
For the embodiments, each arm of the u-shaped holder may include a plurality of rows of plurality openings 204 configured to enable a brace to be received and held in one of a number of holding positions, using e.g. nails, through a selected subset of the openings 204. As described earlier, the brace may or may not be supported by the ground, e.g. the brace may be held in free space hanging over a trench.
