DETAILED DESCRIPTION

[0020] The presently disclosed subject matter now will be described more fully hereinafter with reference to the accompanying Drawings, in which some, but not all embodiments of the presently disclosed subject matter are shown. Like numbers refer to like elements throughout. The presently disclosed subject matter may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Indeed, many modifications and other embodiments of the presently disclosed subject matter set forth herein will come to mind to one skilled in the art to which the presently disclosed subject matter pertains having the benefit of the teachings presented in the foregoing descriptions and the associated Drawings. Therefore, it is to be understood that the presently disclosed subject matter is not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims.

[0021] In some embodiments, the presently disclosed subject matter may provide a masonry form system and method including plastic reusable masonry form members. Examples of reusable masonry form members may include, but are not limited to, straight members, increment members (or spacers), corner members, U-shaped members, and anti-spread clips. Further, a method of using the masonry form system is provided.

[0022] Referring now to FIG. 1 is a plan view of an example of the presently disclosed masonry form system 100 which may include plastic reusable masonry form members. For example, masonry form system 100 may include any number and/or arrangement of a variety of reusable masonry form members. Examples of reusable masonry form members may include, but are not limited to, straight members 110, increment members 112, corner members 114, U-members 116, and anti-spread clips 130. In the example shown in FIG. 1, the arrangement of straight members 110, increment members 112, corner members 114, U-members 116, and anti-spread clips 130 may provide a masonry form for building footings in a residential or commercial application. Namely, FIG. 1 shows an outer rectangular-shaped form 140, an inner rectangular-shaped form 142, and two square-shaped lolly column forms 144. Concrete 150 may be poured in the area between outer rectangular-shaped form 140 and inner rectangular-shaped form 142. Also, concrete 150 m be poured in each of the two lolly column forms 144.

[0023] The reusable masonry form members, such as straight members 110, increment members 112, corner members 114, U-members 116, and anti-spread clips 130, may be polymer-based members that are durable, moisture resistant, washable, and lightweight. In one example, the reusable masonry form members may be formed of thermoplastic material. The thermoplastic masonry form members may be substantially hollow, and may include a gap of about two (2) inches between its opposing vertical walls 111a and 111b. With reference to FIGS. 2-3, the thermoplastic masonry form members may further include internal vertical ribs 113 sandwiched between opposing vertical walls 111a and 111b of the thermoplastic masonry form members to provide added strength and stability. In one example, internal vertical ribs 113 may be evenly spaced along a length of the thermoplastic masonry form member. Thermoplastic masonry form members may further include one or more internal horizontal ridges 115. In one example, an internal horizontal ridge 115 may run the length of the thermoplastic masonry form member at about its vertical midpoint. In one embodiment, thermoplastic masonry form members may be filled with foam to provide added strength and to provide capability to withstand a broader range of heat and cold. Additionally, the reusable masonry form members of masonry form system 100 may be used in place of conventional wood forms, yet the installation is similar to wood forms (a familiar process for installers).

[0024] FIG. 4 shows various views of an example of straight member 110, which may be a straight reusable masonry form member. In one example, straight member 110 may be about 2 inches thick, about 12 inches high, and any length, for example, from about 2 feet long to about 12 feet long. Increment member 112 is a type of straight member 110 albeit a short length straight member 110. Increment members 112 may be used in combination with straight members 110 to achieve any length required that conform to a typical form.

[0025] Referring still to FIG. 4, once the reusable masonry form members have been placed, they may be secured in place by driving rebar, or other suitable securing mechanism, vertically through one or more channels 148. The channels 148 may be formed as plastic through-holes; or alternatively may include a sleeve made of various materials, such as galvanized metal, stainless steel, or other suitably durable material. In one example, channels 148 may be space about every two (2) feet from one another along a length of the reusable masonry form member. Further, channels 148 may have a diameter sufficient for receiving a standard piece of rebar, for example, channels 148 may have a diameter the range of about an inch to about of an inch.

[0026] FIG. 5 shows various views of an example of the reusable increment member 112. In one example, increment member 112 may be about 2 inches thick, about 12 inches high, and available in various lengths, such as, but not limited to, 6 inches, 7 inches, 8 inches, and 9 inches long. Both straight member 110 and increment member 112 may have a connector tab 120 on one end and a connector slot 122 on the opposite end.

[0027] Alternatively, and with reference to FIGS. 6 and 7, one or more straight members 110 and increment members 112 may have connector tabs 120 on both ends (see FIG. 6), or may have connector slots 122 on both ends (see FIG. 7).

[0028] FIG. 8 illustrates a top view of an example of an arrangement of the reusable straight member 110, the reusable increment member 112, and a reusable corner member 114. With further reference to FIGS. 9 and 10, corner member 114 may be designed to provide a 90 degree corner member. In one non-limiting example, corner member 114 may be about 2 inches thick, about 12 inches high, and each side of corner member 114 may be, for example, about 26 inches long. Like straight member 110 and increment member 112, corner member 114 may have a connector tab 120 on one end and a connector slot 122 on the opposite end, or alternatively may have connector tabs 120 on both ends or connector slots 122 on both ends.

[0029] With reference to FIG. 11, connector tab 120 and connector slot 122 may be designed to be fitted together in a slideable fashion for connecting end-to-end any two adjacent form members. For example, and referring back to FIG. 8, the connector slot 122 of a straight member 110 may be engaged with the connector tab 120 of an increment member 112, then the connector slot 122 of the increment member 112 may be engaged with the connector tab 120 of a corner member 114, and then the connector slot 122 of the corner member 114 may be engaged with the connector tab 120 of the next member.

[0030] Connector tab 120 and connector slot 122 is just one example of how adjacent form members may be connected together. Any other suitable technique or mechanism for connecting adjacent form members may alternatively be used.

[0031] FIG. 12 and FIG. 13 illustrate top views of examples of the reusable U-members 116. U-members 116 are U-shaped masonry form members. In one non-limiting example, U-member 116 may be about 2 inches thick, about 12 inches high, about 28 inches wide, and about 14 inches deep. FIG. 12 shows two types of U-members 116. Namely, a Type A that has a connector slot 122 at both ends and a Type B that has a connector tab 120 at both ends. In this example, the connector tabs 120 of the Type B U-member 116 may engage with the connector slots 122 of the Type A U-member 116. Further, in this example, forming lolly column form 144 may require one Type A U-member 116 and one Type B U-member 116. By contrast, FIG. 13 shows a pair of Type C U-members 116. Namely, a Type C U-member 116 has a connector tab 120 at one end and a connector slot 122 at the opposite end. In this way, two Type C U-members 116 may be oppositely oriented and then engaged. In this example, lolly column form 144 may be formed using two of the same type of U-members 116; namely, two Type C U-members 116.

[0032] FIG. 14 shows various views of example reusable anti-spread clips 130. Anti-spread clip 130 may include a cross member 132 and two side members 134 (one on each end of cross member 132). Further, each of the side members 134 may have a lip 136. In one example, for a 24 inch wide footings, anti-spread clip 130 may have an overall length of about 33 inches, a width of about 3 inches, and an overall thickness of about 2 inches. In this example, the space between the two side members 134 may be, for example, about 29 inches, and the space between the tips of lips 136 may be, for example, about 28 inches. In another example, for 16 inch wide footings, anti-spread clip 130 may have an overall length of about 25 inches, a width of about 3 inches, and an overall thickness of about 2 inches. In this example, the space between the two side members 134 may be, for example, about 21 inches, and the space between the tips of lips 136 may be, for example, about 20 inches.

[0033] Anti-spread clip 130 is designed to span across, for example, a pair of straight members 110 as shown in FIG. 1. The two side members 134 and their lips 136 are designed to grip the straight members 110. Accordingly, in masonry form system 100, anti-spread clips 130 may be installed as needed to prevent other members from spreading once filled with concrete 150.

[0034] FIG. 15 illustrates a flow diagram of an example of a method 200 of using the presently disclosed masonry form system 100. Method 200 may include, but is not limited to, the following steps.

[0035] At a step 210, the reusable members of masonry form system 100 may be provided. For example, an assortment of straight members 110 of various lengths, an assortment of increment members 112 of various lengths, corner members 114, U-members 116, and anti-spread clips 130 may be provided at the job site.

[0036] At a step 215, the first two reusable members of masonry form system 100 may be selected (according to plan), positioned (according to plan), and then connected together. In one example, two straight members 110 may be selected, positioned, and then connected together using their respective connector tabs 120 and connector slots 122. In another example, a straight member 110 and an increment member 112 may be selected, positioned, and then connected together using their respective connector tabs 120 and connector slots 122. In yet another example, a straight member 110 and a corner member 114 may be selected, positioned, and then connected together using their respective connector tabs 120 and connector slots 122.

[0037] At a decision step 220, it is determined whether the masonry form is complete according to plan. If the masonry form is not complete, then method 200 may proceed to method step 225. However, if the masonry form is complete then method 200 may proceed to method step 230.

[0038] At a step 225, the next reusable member of masonry form system 100 may be selected (according to plan), positioned (according to plan), and then connected to one of the previously installed reusable members. For example, according to plan, a straight member 110 of a certain length, an increment member 112 of a certain length, a corner member 114, or a U-member 116 may be selected, positioned (according to plan), and then connected to one of the previously installed reusable members. In another example, one or more anti-spread clips 130 may be selected and installed. Method 200 may then return to decision step 220.

[0039] At a step 230, concrete 150 may be poured into the reusable masonry form built using masonry form system 100 and then allowed to set.

[0040] At a step 235, the reusable masonry form built using masonry form system 100 may be disassembled and then stored and/or transported away. For example, all of the used reusable members of masonry form system 100 (e.g., straight members 110, increment members 112, corner members 114, U-members 116, and anti-spread clips 130) may be disengaged from one another, cleaned of any excess concrete, and then stored and/or transported away for reuse at another time and/or another job site.

[0041] Referring again to FIG. 1 through FIG. 15, the presently disclosed masonry form system 100 and method 200 including plastic reusable masonry form members may be summarized as follows.

[0042] In masonry form system 100, the reusable masonry form members (e.g., straight members 110, increment members 112, corner members 114, and U-members 116) may be placed vertically as they measure 2 inches12 inches and placed, pulling off of corners that have been staked by a surveyor, which would be based on blueprints for a particular house or building. The reusable masonry form members may be placed in a trench based on the building plan. The reusable masonry form members may be connected by sliding male ends (e.g., connector tabs 120) and into female ends (e.g., connector slots 122). Forms (e.g., straight members 110) may be provided, for example, at from about 2 feet to about 12 feet in length and spacers (e.g., increment members 112) may be provided to achieve any length required that conform to typical form.

[0043] Once the reusable masonry form members have been placed, they may be secured by driving rebar vertically through the channels 148 provided, which may be a formed plastic through-hole, or could alternatively be a galvanized metal or stainless steel sleeve. A string line or transit may be used to keep the alignment of the form straight and level using material such as slate or other shimming material. In one example, masons pins may be placed on the outside of the reusable masonry form members to prevent the weight of the concrete from pushing out the forms or spreading them.

[0044] At this point, if the building plan calls for horizontal and/or vertical rebar, the rebar may be placed inside the reusable masonry form members. The rebar usually sit on metal chairs, the number and size of such rebar would be specified in the building plans. After rebar is in place, it could be connected to the vertical rebar in the reusable masonry form members, which has been placed, for example, at about every 2 feet.

[0045] Once the masonry form is level, dimensions checked, and rebar installed, anti-spread clips 130 may optionally be installed with the masonry form. The anti-spread clips 130 may, for example, be about 24 inches long and may snap onto the vertical form members to prevent the concrete from pushing out the form members. The anti-spread clips 130 may be installed as needed, usually about 4 feet on center. 16-inch anti-spread clips 130 may be provided for smaller footings. Once the concrete has been poured and starts to set, the anti-spread clips 130 may be removed, cleaned of any excess concrete, and reused.

[0046] After pour, e.g., one day after pour, the reusable masonry form members (e.g., straight members 110, increment members 112, corner members 114, and U-members 116) may be removed while trying not to damage them, although they are formed of durable, moisture resistant material that can stand reuse. A benefit of the presently disclosed masonry form system 100 including plastic reusable masonry form members is that it is lighter than wood or steel, easier to remove and clean than wood or steel, and because it can be used again and again it saves natural resources.

[0047] The reusable masonry form members may further be foam filled to provide added structural strength. In one example, the reusable masonry form members may be filled with a foam, for example, Polycel Structural Foam, or other suitable foam filler.

[0048] The reusable masonry form members may have one or more horizontal ribs 152 along their exterior walls that may be, for example, 8 inches and/or 10 inches high based on the required footing depth. The one or more horizontal ribs 152 may extend about a 0.5 inch out from the exterior surface of the reusable masonry form members to allow for a trowel to be run along it to ensure a level footing.

[0049] Following long-standing patent law convention, the terms a, an, and the refer to one or more when used in this application, including the claims. Thus, for example, reference to a subject includes a plurality of subjects, unless the context clearly is to the contrary (e.g., a plurality of subjects), and so forth.
