DETAILED DESCRIPTION
[0021] The disclosed adjustable concrete forms will become better understood through review of the following detailed description in conjunction with the figures. The detailed description and figures provide merely examples of the various inventions described herein. Those skilled in the art will understand that the disclosed examples may be varied, modified, and altered without departing from the scope of the inventions described herein. Many variations are contemplated for different applications and design considerations; however, for the sake of brevity, each and every contemplated variation is not individually described in the following detailed description.
[0022] Throughout the following detailed description, examples of various adjustable concrete forms are provided. Related features in the examples may be identical, similar, or dissimilar in different examples. For the sake of brevity, related features will not be redundantly explained in each example. Instead, the use of related feature names will cue the reader that the feature with a related feature name may be similar to the related feature in an example explained previously. Features specific to a given example will be described in that particular example. The reader should understand that a given feature need not be the same or similar to the specific portrayal of a related feature in any given figure or example.
Definitions
[0023] The following definitions apply herein, unless otherwise indicated.
[0024] Substantially means to be more-or-less conforming to the particular dimension, range, shape, concept, or other aspect modified by the term, such that a feature or component need not conform exactly. For example, a substantially cylindrical object means that the object resembles a cylinder, but may have one or more deviations from a true cylinder.
[0025] Comprising, including, and having (and conjugations thereof) are used interchangeably to mean including but not necessarily limited to, and are open-ended terms not intended to exclude additional elements or method steps not expressly recited.
[0026] Terms such as first, second, and third are used to distinguish or identify various members of a group, or the like, and are not intended to denote a serial, chronological, or numerical limitation.
[0027] Coupled means connected, either permanently or releasably, whether directly or indirectly through intervening components.
Adjustable Concrete Forms
[0028] With reference to the figures, adjustable concrete forms will now be described. The adjustable concrete forms discussed herein function to define the shape and slope of concrete as it sets. Often, the adjustable concrete forms define the shape and slope of ADA ramps made from concrete.
[0029] The reader will appreciate from the figures and description below that the presently disclosed novel adjustable concrete forms address many of the shortcomings of conventional adjustable concrete forms. For example, the novel adjustable concrete forms enable conveniently and effectively building ADA ramps that meet applicable tolerance requirements. With the novel adjustable concrete forms, workers with less skill and experience can effectively form ADA ramps that meet the requirements than is possible using conventional techniques to form ADA ramps.
[0030] Desirably, the novel adjustable concrete forms provide an effective and simple system for making ADA ramps with concrete. The novel adjustable concrete forms reduce the time and labor currently required for building ADA ramps. The novel adjustable concrete forms reducing the time and labor required to install ADA ramps reduces the overall cost and effort to install ADA ramps.
Adjustable Concrete Form Embodiment One
[0031] With reference to
[0032] Adjustable concrete form 100 may be used to create concrete structures in a wide variety of shapes and sizes. A common application for adjustable concrete form 100 is to create ADA ramps. In particular, adjustable concrete form 100 may be used to build ADA ramps that meet applicable requirements, including slope, length, and height requirements.
[0033] The size of the adjustable concrete form varies in different examples. Some adjustable concrete form examples are larger than depicted in the figures while other examples are smaller. In general, the size of the adjustable concrete form will be selected to accommodate the size of the structure sought to be formed from concrete, such as an ADA ramp, while also balancing weight and transport convenience factors.
[0034] Adjustable concrete form 100 includes a landing form 101 and a ramp form 102. In some examples, the adjustable concrete form does not include one or more features included in adjustable concrete form 100. In other examples, the adjustable concrete form includes additional or alternative features. The components of adjustable concrete form 100 are discussed in the sections below.
Landing Form
[0035] Landing form 101 functions to define the shape and size of a landing formwork. The landing formwork corresponds to a landing of an ADA ramp formed from concrete. Concrete is poured into landing form 101, allowed to set into the desired shape of the landing with initial strength characteristics, and then allowed to cure to full strength in the desired landing shape.
[0036] The size and shape of the landing form may differ from the size and shape of landing form 101 depicted in the figures. Larger ADA ramp landings may require larger landing forms while smaller landing designs may allow for smaller landing forms.
[0037] As can be seen in
Jacks
[0038] Jacks 110 function to support brace members 120 from the ground or other support surface. In particular, jacks 110 enable supporting brace members 120 at selected heights above the ground. The slope of the landing formwork formed by landing form 101 and the slope of the ramp formwork formed by ramp form 102 are adjustable by selectively adjusting the height at which jacks 110 support landing brace members 120.
[0039] As shown in
[0040] With reference to
[0041] As depicted in
[0042] Jacks 110 are operable to selectively adjust their height.
[0043] Selectively adjusting the height of jacks 110 functions to selectively adjust the height above the ground of landing brace members 120 supported on jacks 110. Further, selectively adjusting the height of jacks 110 functions to selectively adjust the height above the ground of ramp brace members 140 coupled to landing brace members 120. By adjusting the height of landing brace members 120 and ramp brace members 140 above the ground, the slope of the landing formwork and the ramp formwork may be adjusted.
[0044]
Landing Brace Members
[0045] Landing brace members 120 cooperate to define a landing formwork to establish a desired shape for a landing of an ADA ramp. Landing brace members 120 serve as form walls containing poured concrete as the concrete sets. In some examples, additional form walls are supported by landing brace members 120 and/or stakes 160 coupled landing brace members 120.
[0046]
[0047] In the present example, as shown in
[0048] First brace member 121 is pivotally coupled to one of ramp brace members 140. Second brace member 122 is spaced from and parallel to first brace member 121. Second brace member 122 is pivotally coupled to one of ramp brace members 140.
[0049] First cross member 123 and second cross member 124 extend between first brace member 121 and second brace member 122 and are spaced from each other. First cross member 123 is distal ramp form 102 and second cross member 124 is proximate ramp form 102.
[0050] First cross member 123 is length adjustable, which enables the width of landing form 101 to be adjusted. In the present example, second cross member 124 has a fixed length, but can be configured to have an adjustable length in other examples.
[0051] With reference to
[0052] Inner cross member arm 130 is moveably disposed within the first cross member sleeve 133 and in second cross member sleeve 134. The effective length of first cross member 123 can be adjusted by sliding inner cross member arm 130 relative to first cross member sleeve 133 and second cross member sleeve 134. Adjusting the effective length of first cross member 123 adjusts the width of landing form 101.
[0053] With reference to
[0054] First cross member 223 includes a first outer cross member arm 231, a second cross member arm 232, an inner cross member arm 230, and cross member adjustment shafts 235. Second outer cross member arm 232 is selectively spaced from first outer cross member arm 231. First outer cross member arm 231 defines a first cross member sleeve 233 and cross member ports 237. Second outer cross member arm 232 defines a second cross member sleeve 234.
[0055] First cross member adjustment shafts 235 are configured to extend through cross member ports 237. Cross member ports 237 and cross member adjustment shafts 235 are complementarily threaded.
[0056] In more detail, cross member adjustment shafts 235 may selectively extend through cross member ports 237 sufficient to press against inner cross member arm 230 disposed within first cross member sleeve 233. Cross member adjustment shafts 235 pressing against inner cross member arm 230 within cross member sleeve 233 fixes the position of inner cross member arm 230 relative to first outer cross member arm 231. In this manner, the effective length of first cross member 223 may be fixedly adjusted.
[0057] In some examples, the first cross member includes a single sleeve and shaft for fixing the effective length of the first cross member. In certain examples, the second outer cross member arm includes an adjustment sleeve and shaft in addition or alternatively to the adjustment sleeve and shaft in the first outer cross member arm.
[0058] Returning attention to
[0059] As shown in
[0060] As shown in
[0061] Vertical bearings 125 and 126 facilitate pivotally coupling brace members 121 and 122 to ramp brace members 140. As highlighted in
[0062] With reference to
[0063] As shown in
[0064]
Ramp Form
[0065] Ramp form 102 serves to define a ramp formwork configured to contain poured concrete in a desired ramp shape while the concrete sets. Ramp form 102 also functions to selectively couple adjustable concrete form 100 to a structure, such as a curb.
[0066] Ramp form 102 is pivotally coupled to landing form 101. The pivotal coupling enables the width of the ramp formwork defined by ramp form 102 to be adjusted.
[0067] As shown in
[0068] In the example shown in
Ramp Brace Members
[0069] Ramp brace members 140 define the ramp formwork of ramp form 102. The ramp formwork defined by ramp brace members 140 is configured to contain poured concrete in a desired ramp shape while the concrete sets. Ramp brace members 140 cooperate with clamps 150 to couple adjustable concrete form 100 to a structure, such as a curb as shown in
[0070] As shown in
[0071] Ramp brace members 140 are length adjustable, but some examples utilize fixed length ramp brace members. Ramp brace members 140 being length adjustable enables ramp form 102 to define ramp formworks yielding different length ramps. Ramp brace members 140 being length adjustable also enables them to cooperate with jacks 110 to adjust the slope of the ramp formwork.
[0072] As shown in
[0073] With reference to
[0074] Ramp adjustment shafts 145 are configured to extend through ramp arm ports 144 and to press against inner ramp arm 141 disposed within ramp sleeve 143. Ramp adjustment shafts 145 pressing against inner ramp arm 141 within ramp sleeve 143 fixes the position of inner ramp arm 141 relative to outer ramp arm 142. Fixing the position of inner ramp arm 141 relative to outer ramp arm 142 fixes the adjusted effective length of ramp brace member 140.
