Description

    BACKGROUND
  • The present invention relates generally to concrete forms and more particularly, to concrete form anchor devices operable to support and retain concrete forms in position during the pouring and formation of a concrete trench.
  • Forming trenches in concrete construction presents a problem due to the nature of the typical concrete mixes being semi-liquids. Therefore, when concrete is poured, forms tend to gravitate or float upwards if not attached to the ground. Current practices for preventing floating of the form include driving rebar into the ground along one side of the form, attaching wire to the rebar, extending the wire over the form, and attaching the wire to rebar driven on the opposite side of the form. The rebar in this method sometimes releases from the soil which allows the form to float or gravitate upwards. This method of forming concrete trenches is labor intensive and costly.
  • SUMMARY
  • One embodiment of the present application discloses a concrete form system which is capable of maintaining a concrete form in a preset position during the pouring of concrete to form a trench. Other embodiments include unique apparatus, devices, systems, and methods for maintaining concrete forms in preset positions to form concrete trenches. Further embodiments, forms, objects, features, advantages, aspects, and benefits of the present application shall become apparent from the detailed description and figures included herewith.

  • DETAILED DESCRIPTION
  • For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated device, and such further applications of the principles of the invention is illustrated therein being contemplated as would normally occur to one skilled in the art to which the invention relates.
  • With reference to FIG. 1, there is illustrated a concrete form system 10 cooperating with ground 12 for use in forming a trench 14 with concrete 16. System 10 could be used in a wide variety of concrete forming applications and includes a concrete form 20 and a plurality of concrete anchor devices 30. Although system 10 is illustrated in this form for use in connection with the formation of trench 14, it is envisioned that system 10 could find application in a wide variety of concrete forming applications outside of trenches such as foundations, roads, and curbs, among other applications. Concrete form 20 could be formed from any number of materials including plastics, metal, wood, composites, or any other known materials for forming concrete. Furthermore, certain forms of the present application contemplate anchor devices 30 being formed from a variety of materials including, but not limited to, metal, galvanized metal, steel, alloys, wood, and plastic, to name a few.
  • Concrete form 20 includes a plurality of concrete engaging surfaces 34 that are surrounded by concrete 16 once it is poured around concrete form 20 and a plurality of open surfaces 36 that are not contacted by concrete 16. In this form, concrete form 20 is defined by a pair of opposing side form members 40 and a bottom or base form member 50 which cooperate together to define a U-Shaped cross-section to form trench 14. In some forms, the concrete form 20 may have other shapes and may include rounded surfaces. For example, the concrete form 20 may be V-shaped, or may be D-shaped, to set forth just a few non-limiting examples. Accordingly, any shape of trench or other concrete construction may be built using the devices and methods described herein. In one form the opposing side form members 40 and base form member 50 may be separate members coupled together using any suitable technique, such as bolting, nailing, screwing, and the like, to set forth just a few non-limiting examples. Concrete form 20 could include multiple form members that define trenches 14 running in various directions. Additionally, in other forms, concrete form 20 could be a unitary structure or contain multiple components coupled together.
  • Referring to FIG. 2, which illustrates a close up view of the circled area indicated in FIG. 1, concrete form 20 includes at least one fastener opening 52 for each anchor device 30 being used and is removably coupled to anchor device 30 with a coupling assembly 60. In some forms, concrete form 20 may have multiple fastener openings 52 for one or more than one anchor device 30. As illustrated in FIG. 1, when concrete form 20 is connected with anchor device 30, anchor device 30 holds or positions concrete form 20 above ground 12 a predetermined distance. In other words, base 50 of concrete form 20 is held suspended above ground 12 at a desired level. This ensures that when concrete 16 is poured, concrete 16 is capable of forming a trench 14 in concrete 16 after it hardens and concrete form 20 is removed from concrete 16. The predetermined distance that the concrete form is positioned above ground 12 may be constant across any dimension of the concrete form 20, or may vary, depending on the requirements of any given application, ground surface preparation, the shape of the concrete form, among possible others. In some forms, a portion or portions of the concrete form may contact the ground 12.
  • As illustrated in FIG. 2, in one form of the present application, coupling assembly 60 comprises a bolt 70, a washer 80, and a nut 90. In this form, during setup of concrete form 20, bolt 70 is inserted through opening 52 of concrete form 20 and through an opening or aperture 190 of anchor device 30.
