CROSS-REFERENCE TO RELATED APPLICATION
This application claims the benefit of U.S. Provisional Application No.
61/889,119, filed October 10, 2013, the disclosure of which is hereby expressly incorporated in its entirety by reference herein.
BACKGROUND
Concrete structures, such as foundations, walls, beams, and columns, are formed using the aid of concrete form assemblies, often composed of plywood panels. The forms serve to mold the poured, liquid concrete to a shape during the curing stage. Many form assemblies utilize spacers in order to secure the form panels. Spacers generally hold a corresponding pair of form panels apart at a pre-determined distance. The number and location of spacers allow the concrete to be poured in the form assembly without extensive bowing of the form panels, which ensures the desired shape of the finished concrete structure is retained and excessive concrete material is not used. When the curing stage is complete, the form assembly must be dismantled, the process of which often leads to damage of the concrete form panels, requiring replacement, rather than reuse in a subsequent form assembly. The present invention provides concrete form spacers which conveniently bend with a hammer strike, thereby freeing the concrete form panels for non-destructive removal, allowing the form panels to be reused in a subsequent form assembly.

Embodiments of the present disclosure are generally directed to concrete form spacers with enhanced concrete form insertion and removal features. In general, examples of the concrete form spacers described herein are capable of attaching to a mounting surface and retain concrete forms in a spaced relationship to each other to allow the concrete structure to be poured and cured in place. The embodiments illustrated in the FIGURES have been designed for use with concrete form assemblies. However, the embodiments of the present disclosure may also be used in other types of poured form applications which are also within the scope of this disclosure.
Referring initially to FIGURES 1-3, a concrete form spacer 100 of the present disclosure is illustrated as composed of an elongate flat web 112 with end flanges 114 projecting upwardly from the ends of the elongate flat web 112. Tabs 116 project laterally from the elongate flat web 112 at a location spaced inwardly along the elongate flat web 112 from the end flanges 114. Each corresponding pair of tabs 116 and end flanges 114 form an upwardly open pocket 118 configured to closely receive a concrete form panel P
(see e.g., FIGURE 7) therebetween. In this regard, the width of each pocket 118 is typically slightly larger than the width of the concrete form panel P.
Each tab 116 may be formed by piercing the elongate flat web 112 and then bending the pierced portion of the elongate flat web 112 upwardly so that the tab 116 is projecting laterally from the elongate flat web 112, generally in the direction of the corresponding end flange 114. In this regard, the upper end of tab 116 may be rounded so as not to present a sharp point. In other embodiments, the tab portion can be created by numerous other means, including welding or otherwise attaching tab 116 to elongate flat web 112.
In the illustrated embodiment shown in FIGURE 1, tabs 116 are projected at a slight angle away from the pockets 118 in order to guide the concrete form panel P
down into pockets 118. In this regard, the tab projection angle 134 is in the range of about 90 degrees to 70 degrees from the elongate flat web 112 in the angle location depicted in FIGURE 1. In other embodiments, tabs 116 may be curved or rounded in a manner configured to guide the concrete form panel P into pocket 118.
The end flanges 114 include form securing through holes 120 which allow a form anchoring fastener 158 (see e.g., FIGURE 7) to optionally secure the concrete form panel P in pocket 118. Elongate flat web 112 also includes spacer securing through holes 122 which allow the insertion of an anchoring fastener 160 (see e.g., FIGURE 7) configured to attach the concrete form spacer 100 to a mounting surface 152 where the concrete structure will be formed, (e.g., using a concrete nail to attach the spacer to a concrete foundation footing).
As shown most clearly in FIGURE 1, the end flange 114 includes a distal flange tip portion 124 that is flared away from form pocket 118 and is configured to guide concrete form panel P down into pocket 118. In the illustrated embodiment, flange tip portion 124 is generally planar and disposed at an angle 126 of about 45 degrees relative to the end flange 114. However, in other embodiments, flange tip portion 124 may be disposed at an angle 126 in the range of about 20 degrees to 70 degrees relative to the end flange 114.
In further embodiments of the present disclosure, flange tip portion 124 may be rounded or curved away from the pocket 118 so as to present a convex shape toward the concrete form panel P when in place within pocket 118.
Each flange tip portion 124 may be formed by bending the end flanges 114 during formation of the concrete spacer 100. Alternatively, flange tip portion 124 may be initially composed of a separate member welded or otherwise attached to the end flange 114.
The flange tip portions 124 provide an advantage over current concrete form spacers of the art. In use, form spacers are configured to hold concrete form panels in a spaced relationship from each other while the concrete in the form assembly cures.
Once curing has completed, the form panels are removed from the form spacers. Typically, this requires that the end flanges of the form spacers are bent away from the form panel so they are no longer bearing against the form panels P and are no longer perpendicular to the elongate web of the form spacer. Other concrete form spacers of the art require forcing the claw portion of a hammer, or a pry bar, between the end flange and the form panel to force the end flange away from the form panel. This often causes damage to the form panel, which is typically composed of plywood.
In contrast, the concrete form spacer 100 of the present disclosure, by utilizing end flanges 114, each with flared flange tip portion 124, makes it possible to simply use a hammer or similar device to strike the protruding flange tip portion 124, causing the end flange 114 to bend away from the concrete form panel P. As a result, damage to the concrete form panel P
is avoided or at least reduced. Moreover, with the end flange 114 bent away, the pocket 118 becomes wider than the concrete form panel P, encouraging or facilitating removal of the form panel P from the cured concrete wall and the concrete form spacer 100.
Next, referring to FIGURES 4-6, a second concrete form spacer 130 is illustrated. As in concrete form spacer 100, concrete form spacer 130 includes an elongate flat web 112A
having at one end thereof an end flange 114A projecting upwardly from one end of the elongate flat web 112A. The upper end of the end flange 114A flares outwardly at distal flange tip portion 124A. As in concrete form spacer 100, the flange tip portion 124A of end flange 114A may be generally planar, curved or rounded, as desired. In addition, a tab 116A
projects laterally from the elongate flat web 112A at a location spaced inwardly along the elongate flat web 112A from the end flange 114A. As in tab 116, shown in FIGURES 1-3, tab 116A of FIGURES 4-6 can also be formed by piercing the elongate flat web 112A and then bending the pierced portion of the elongate flat web 112A upwardly so that the tab 116A
is projecting laterally from the elongate flat web 112A in the direction of the corresponding end flange 114A. Also, as in concrete form spacer 100, a form securing hole 120A may be formed in end flange 114A for reception of a form anchoring fastener 158 or other type of fastener. Likewise, spacer securing holes 122A may be included in the elongate flat web 112A to allow the insertion of an anchoring fastener 160 configured to attach the concrete form spacer 130 to a mounting surface 152 where the concrete structure will be formed (see FIGURE 7).
Referring specifically to FIGURES 4 and 5, the elongate flat web 112A forms an elongated flat section with a series of spaced-apart, transverse slots 36 formed in the elongate flat web 112A. In addition, notches 138 are formed on each edge of the elongate flat web 112A aligning with the locations of the transverse slots 136. The transverse slots 136 and corresponding notches 138 enable the elongated flat section of the elongate flat web 112A to be relatively easily bent at such locations. In other embodiments, notches 138 may be omitted (see e.g., FIGURE 11). In use, as described more fully below, the elongated flat section of elongate flat web 112A is bent upwardly at one of the locations of the transverse slots 136 so as to form a bent end flange 154. By providing a series of transverse slots 136 and corresponding notches 138, the concrete form spacer 130 can be used to form walls of various widths.
As shown most clearly in FIGURE 5, additional form pocket holes 140 are spaced at a distance away from each of the transverse slot 136 and notch 138 locations.
Such through holes are shown to each be to the left of a corresponding set of transverse slots 136 and notches 138. As shown in FIGURE 7, a form pocket nail 156 or other fastener can be engaged through the form pocket holes 140 so as to function in the manner of tab 116A, thereby to bear against the inside of the concrete form panel P, as shown. Also, additional form securing holes 120A are located on the rightmost portion of the elongated flat section of the elongate flat web 112A. Once bent end flange 154 is formed upwardly, the additional form securing holes 120A can then be used to receive a form anchoring fastener 158 for attaching the concrete form panel P to the concrete form spacer 130 as shown in FIGURE 7.
As shown in FIGURE 7, the embodiment of concrete form spacer 130 may be especially advantageous when utilized after a concrete form panel P is initially assembled in place and thereafter it is determined that further concrete form spacers 130 are needed, especially at the bottom edges of the form assembly. Occasionally, it is determined that an insufficient number of concrete form spacers have been used once the form assembly is partially constructed. Likewise, additional concrete form spacers 130 can be used to reinforce the form assembly once the concrete has been poured if it is determined that the form assembly requires more support due to outward bowing of the form panels in certain locations.
In this regard, the elongate flat web 112A of concrete form spacer 130 can be driven across the mounting surface 152 underneath the form assembly in place, since the end of the elongate flat web 112A opposite the end flange 114A is flat, and thus can pass beneath the form assembly without obstruction or disassembly of the concrete form panels P.
Once concrete form spacer 130 is in place and the lower edge of one concrete form panel P is engaged within pocket 118A, the opposite end of elongate flat web 112A can be bent upwardly to form bent end flange 154 to bear against the outside surface of the adjacent concrete form panel P. Then, a form pocket nail 156 or other type of fastener can be optionally inserted within form pocket hole 140 so as to bear against the inside surface of the concrete form panel P. Also, as discussed above, form anchoring fasteners 158 or other fasteners can be engaged through the form securing holes 120A that extend upwardly along the outside surface of the concrete form panel P in the bent end flange 154.
Referring now to FIGURES 8-12, concrete form spacers in accordance with other embodiments of the present disclosure will be described in more detail. These concrete form spacers are substantially identical in materials and operation as the previously described embodiments, except for differences regarding the shape of tab 216 (FIGURES 8 and 9), and tab 216A and removal of notches 138 (FIGURES 10-12), which will be described in greater detail below. For clarity in the ensuing descriptions, numeral references of like elements of the concrete form spacers 100 and 130 are similar, but are in the 200 and 230 series for the illustrated embodiment of FIGURES 8-12.
As shown in FIGURES 8 and 9, a third concrete form spacer 200 is illustrated.
Concrete form spacer 200 is substantially identical to concrete form spacer 100, except that tab 216 additionally includes distal tab tip portion 232 that is flared away from the pocket 218, which is configured, in conjunction with flange tip portion 224, to guide concrete form panel P
down into pocket 218. In the illustrated embodiment of concrete form spacer 200, tab tip portion 232 is disposed at an angle 228 at about 45 degrees relative to tab 216. However, in other embodiments, tab tip portion 232 may be disposed at an angle 228 in the range of about 20 degrees to 70 degrees relative to tab 216. In further embodiments, tab tip portion 232 may be rounded or curved away from pocket 218 so as to present a convex shape toward the concrete form panel P when in place within pocket 218.
Turning now to FIGURES 10-12, a fourth concrete form spacer 230 is illustrated.
Concrete form spacer 230 is substantially identical to concrete form spacer 130, described above, except that tab 216A of concrete form spacer 230 additionally includes distal tab tip portion 232A that is flared away from pocket 218A.

Embodiments of the present disclosure are generally directed to concrete form spacers with enhanced concrete form insertion and removal features. In general, examples of the concrete form spacers described herein are capable of attaching to a mounting surface and retain concrete forms in a spaced relationship to each other to allow the concrete structure to be poured and cured in place. The embodiments illustrated in the FIGURES have been designed for use with concrete form assemblies. However, the embodiments of the present disclosure may also be used in other types of poured form applications which are also within the scope of this disclosure.
Referring initially to FIGURES 1-3, a concrete form spacer 100 of the present disclosure is illustrated as composed of an elongate flat web 112 with end flanges 114 projecting upwardly from the ends of the elongate flat web 112. Tabs 116 project laterally from the elongate flat web 112 at a location spaced inwardly along the elongate flat web 112 from the end flanges 114. Each corresponding pair of tabs 116 and end flanges 114 form an upwardly open pocket 118 configured to closely receive a concrete form panel P
(see e.g., FIGURE 7) therebetween. In this regard, the width of each pocket 118 is typically slightly larger than the width of the concrete form panel P.
Each tab 116 may be formed by piercing the elongate flat web 112 and then bending the pierced portion of the elongate flat web 112 upwardly so that the tab 116 is projecting laterally from the elongate flat web 112, generally in the direction of the corresponding end flange 114. In this regard, the upper end of tab 116 may be rounded so as not to present a sharp point. In other embodiments, the tab portion can be created by numerous other means, including welding or otherwise attaching tab 116 to elongate flat web 112.
In the illustrated embodiment shown in FIGURE 1, tabs 116 are projected at a slight angle away from the pockets 118 in order to guide the concrete form panel P
down into pockets 118. In this regard, the tab projection angle 134 is in the range of about 90 degrees to 70 degrees from the elongate flat web 112 in the angle location depicted in FIGURE 1. In other embodiments, tabs 116 may be curved or rounded in a manner configured to guide the concrete form panel P into pocket 118.
The end flanges 114 include form securing through holes 120 which allow a form anchoring fastener 158 (see e.g., FIGURE 7) to optionally secure the concrete form panel P in pocket 118. Elongate flat web 112 also includes spacer securing through holes 122 which allow the insertion of an anchoring fastener 160 (see e.g., FIGURE 7) configured to attach the concrete form spacer 100 to a mounting surface 152 where the concrete structure will be formed, (e.g., using a concrete nail to attach the spacer to a concrete foundation footing).
As shown most clearly in FIGURE 1, the end flange 114 includes a distal flange tip portion 124 that is flared away from form pocket 118 and is configured to guide concrete form panel P down into pocket 118. In the illustrated embodiment, flange tip portion 124 is generally planar and disposed at an angle 126 of about 45 degrees relative to the end flange 114. However, in other embodiments, flange tip portion 124 may be disposed at an angle 126 in the range of about 20 degrees to 70 degrees relative to the end flange 114.
In further embodiments of the present disclosure, flange tip portion 124 may be rounded or curved away from the pocket 118 so as to present a convex shape toward the concrete form panel P when in place within pocket 118.
Each flange tip portion 124 may be formed by bending the end flanges 114 during formation of the concrete spacer 100. Alternatively, flange tip portion 124 may be initially composed of a separate member welded or otherwise attached to the end flange 114.
The flange tip portions 124 provide an advantage over current concrete form spacers of the art. In use, form spacers are configured to hold concrete form panels in a spaced relationship from each other while the concrete in the form assembly cures.
Once curing has completed, the form panels are removed from the form spacers. Typically, this requires that the end flanges of the form spacers are bent away from the form panel so they are no longer bearing against the form panels P and are no longer perpendicular to the elongate web of the form spacer. Other concrete form spacers of the art require forcing the claw portion of a hammer, or a pry bar, between the end flange and the form panel to force the end flange away from the form panel. This often causes damage to the form panel, which is typically composed of plywood.
In contrast, the concrete form spacer 100 of the present disclosure, by utilizing end flanges 114, each with flared flange tip portion 124, makes it possible to simply use a hammer or similar device to strike the protruding flange tip portion 124, causing the end flange 114 to bend away from the concrete form panel P. As a result, damage to the concrete form panel P
is avoided or at least reduced. Moreover, with the end flange 114 bent away, the pocket 118 becomes wider than the concrete form panel P, encouraging or facilitating removal of the form panel P from the cured concrete wall and the concrete form spacer 100.
Next, referring to FIGURES 4-6, a second concrete form spacer 130 is illustrated. As in concrete form spacer 100, concrete form spacer 130 includes an elongate flat web 112A
having at one end thereof an end flange 114A projecting upwardly from one end of the elongate flat web 112A. The upper end of the end flange 114A flares outwardly at distal flange tip portion 124A. As in concrete form spacer 100, the flange tip portion 124A of end flange 114A may be generally planar, curved or rounded, as desired. In addition, a tab 116A
projects laterally from the elongate flat web 112A at a location spaced inwardly along the elongate flat web 112A from the end flange 114A. As in tab 116, shown in FIGURES 1-3, tab 116A of FIGURES 4-6 can also be formed by piercing the elongate flat web 112A and then bending the pierced portion of the elongate flat web 112A upwardly so that the tab 116A
is projecting laterally from the elongate flat web 112A in the direction of the corresponding end flange 114A. Also, as in concrete form spacer 100, a form securing hole 120A may be formed in end flange 114A for reception of a form anchoring fastener 158 or other type of fastener. Likewise, spacer securing holes 122A may be included in the elongate flat web 112A to allow the insertion of an anchoring fastener 160 configured to attach the concrete form spacer 130 to a mounting surface 152 where the concrete structure will be formed (see FIGURE 7).
Referring specifically to FIGURES 4 and 5, the elongate flat web 112A forms an elongated flat section with a series of spaced-apart, transverse slots 36 formed in the elongate flat web 112A. In addition, notches 138 are formed on each edge of the elongate flat web 112A aligning with the locations of the transverse slots 136. The transverse slots 136 and corresponding notches 138 enable the elongated flat section of the elongate flat web 112A to be relatively easily bent at such locations. In other embodiments, notches 138 may be omitted (see e.g., FIGURE 11). In use, as described more fully below, the elongated flat section of elongate flat web 112A is bent upwardly at one of the locations of the transverse slots 136 so as to form a bent end flange 154. By providing a series of transverse slots 136 and corresponding notches 138, the concrete form spacer 130 can be used to form walls of various widths.
As shown most clearly in FIGURE 5, additional form pocket holes 140 are spaced at a distance away from each of the transverse slot 136 and notch 138 locations.
Such through holes are shown to each be to the left of a corresponding set of transverse slots 136 and notches 138. As shown in FIGURE 7, a form pocket nail 156 or other fastener can be engaged through the form pocket holes 140 so as to function in the manner of tab 116A, thereby to bear against the inside of the concrete form panel P, as shown. Also, additional form securing holes 120A are located on the rightmost portion of the elongated flat section of the elongate flat web 112A. Once bent end flange 154 is formed upwardly, the additional form securing holes 120A can then be used to receive a form anchoring fastener 158 for attaching the concrete form panel P to the concrete form spacer 130 as shown in FIGURE 7.
As shown in FIGURE 7, the embodiment of concrete form spacer 130 may be especially advantageous when utilized after a concrete form panel P is initially assembled in place and thereafter it is determined that further concrete form spacers 130 are needed, especially at the bottom edges of the form assembly. Occasionally, it is determined that an insufficient number of concrete form spacers have been used once the form assembly is partially constructed. Likewise, additional concrete form spacers 130 can be used to reinforce the form assembly once the concrete has been poured if it is determined that the form assembly requires more support due to outward bowing of the form panels in certain locations.
In this regard, the elongate flat web 112A of concrete form spacer 130 can be driven across the mounting surface 152 underneath the form assembly in place, since the end of the elongate flat web 112A opposite the end flange 114A is flat, and thus can pass beneath the form assembly without obstruction or disassembly of the concrete form panels P.
Once concrete form spacer 130 is in place and the lower edge of one concrete form panel P is engaged within pocket 118A, the opposite end of elongate flat web 112A can be bent upwardly to form bent end flange 154 to bear against the outside surface of the adjacent concrete form panel P. Then, a form pocket nail 156 or other type of fastener can be optionally inserted within form pocket hole 140 so as to bear against the inside surface of the concrete form panel P. Also, as discussed above, form anchoring fasteners 158 or other fasteners can be engaged through the form securing holes 120A that extend upwardly along the outside surface of the concrete form panel P in the bent end flange 154.
Referring now to FIGURES 8-12, concrete form spacers in accordance with other embodiments of the present disclosure will be described in more detail. These concrete form spacers are substantially identical in materials and operation as the previously described embodiments, except for differences regarding the shape of tab 216 (FIGURES 8 and 9), and tab 216A and removal of notches 138 (FIGURES 10-12), which will be described in greater detail below. For clarity in the ensuing descriptions, numeral references of like elements of the concrete form spacers 100 and 130 are similar, but are in the 200 and 230 series for the illustrated embodiment of FIGURES 8-12.
As shown in FIGURES 8 and 9, a third concrete form spacer 200 is illustrated.

down into pocket 218. In the illustrated embodiment of concrete form spacer 200, tab tip portion 232 is disposed at an angle 228 at about 45 degrees relative to tab 216. However, in other embodiments, tab tip portion 232 may be disposed at an angle 228 in the range of about 20 degrees to 70 degrees relative to tab 216. In further embodiments, tab tip portion 232 may be rounded or curved away from pocket 218 so as to present a convex shape toward the concrete form panel P when in place within pocket 218.
Turning now to FIGURES 10-12, a fourth concrete form spacer 230 is illustrated.

Additionally, concrete form spacer 230 is depicted without the optional notches 138 of concrete form spacer 130 (see FIGURE 5). In FIGURE 12, concrete spacer form 230 is shown installed with fewer spacer anchoring fasteners 260, and additional form anchoring fasteners 258, as an illustration of an alternate installation embodiment.
However, in other embodiments, any number of fasteners 258 or 260 may be used as necessary to secure the components of the form assembly.
