Abstract

A reusable building foundation system assembled from a plurality of modular composite panels forming the outside and inside containment barriers for a form fill concrete foundation or wall. The panels are removably engageable by an interconnection frame along the vertical edge(2) of each panel having through holes(9) providing for fastening with threaded devices. The horizontal top-line(3) and bottom-line(4) of each inside panel interconnects with the opposing top-line(3) and bottom-line(4) of the outside panel via snap on metal connector bands(6,11) allowing for adjustment of the width and angle of the wall while increasing rigidity to the entire form system. Each panel is constructed and arranged having first a core of rigid, light, and durable medium such as balsa wood or rigid foam shaped into structural support ribs then covered in a coating of fiberglass and resin making for a light, durable and easily transportable system.

  • BRIEF SUMMARY OF INVENTION
  • The invention relates to a system for constructing foundations and walls from poured concrete. The system is lighter than conventional wood panel forms. Assembly before pouring concrete is simplified due to the easy to connect bands and threaded fasteners. Take down or stripping the forms after set-up takes a fraction of the time of conventional forms because the top-line bands quickly pop off allowing for the release of the panels. The panels do not adhere to the concrete due to the frictionless smooth surface of the interior of the panel. The panels are stripped from the setup concrete, washing with brush and water to remove any residuary material thus prepping the panels for the next use. [0022]
  • The principal advantages of the proposed system are the light weight of the panels, quick and easy build-up and take-down, and durability. The panels are more than fifty-percent lighter than wood panels. The system snaps and bolts together in minutes and comes apart faster than it assembles. The frictionless smooth internal surface of the panels allow for quick easy clean-up. The smooth surface also eliminates the need for chemical releasers usually required when using conventional wood forms. With proper care, the panels will not need replacing, unlike the disposable wood panels used in most concrete form applications. The invented system allows for faster build-up, quicker take-down, and immediate clean up at the job site. The light weight of the panels reduces fatigue on laborers. [0023]
  • The reusable modular composite form system has a variety of applications ranging from building foundations to retaining walls. In one embodiment, the forms are custom fabricated to match specific development plans wherein all of the home foundations are identical. The form panels are custom lengths with numbered identifiers expediting the set up process for concrete foundations. [0024]
  • History [0025]
  • Poured concrete foundations and walls have been used for many years. The conventional method for constructing a poured concrete structure would require a build up of formwork consisting of lengths of lumber and plywood sheets. This formwork is temporarily built on sight to provide the form for the poured concrete. The installation of a conventional wood form is labor-intensive, time-consuming, and wasteful of materials. [0026]
  • The poured concrete mixture has a very high amount of moisture that is absorbed by the wood forms making the lumber heavy, warped, and prevents reuse of much of the wood in the form. Repetitive nailing of the forms creates weak spots in the lengths of lumbar creating safety concerns and probable quality control problems. The rough surface of the wood grain causes adhesion by the concrete mixture to the wood. This increases the weight of the forms and increases the labor expense to scrape the set concrete off of the face of the forms. [0027]
  • Concrete releasers are often used to treat the conventional wood forms to limit the amount of moisture absorbed by the wood and encourage easier stripping of the forms once the concrete mixture sets. There are environmental concerns for the use of said releasers because most are petroleum based with the most popular releaser being diesel. The uses of petroleum based releasers have been banned in many states, and expensive commercial substitutes are available on the market but the expense of the releaser often times out weighs the economic expense of replacing the wood forms.[0028]

  • DETAILED DESCRIPTION OF THE DRAWINGS
  • The invention relates to a system for constructing foundations and walls from poured concrete. Referring to the drawing in FIG. 1, the panel form system described demonstrates interior and exterior panels having a top-line [0033] 3 and bottom-line 4, removably engaged to each other via top-line metal bands 6 and bottom-line metal bands 4, said metal bands being of desired length designating the thickness of the foundation or wall, the structural ribs protruding from the exterior side of the panel 5 providing strength and rigidity, the vertical edge 2 having a frame allowing for end to end coupling of the panels designating the length of the foundation or wall, said vertical edge 2 having through holes 9 to facilitate quick and secure interconnection between panels.
  • Referring to FIG. 2 describing the cross sectional view of the form system in use, the structural ribs [0034] 5 opposing to the exterior of the concrete foundation or wall having the bottom-line band 11 secured to base/soil 13, said bottom-line band 11 attaching the bottom of the panels providing for a designated concrete foundation or wall width, top-line band with internal tab 12 attaching the top of the panels providing for a designated concrete foundation or wall width, forming a foundation or wall shaped barrier for the cementious concrete mixture 14 to fill and setup as a concrete foundation or wall.
  • Referring to FIG. 3 describing the cut away view of the individual form panel having the preferred rigid medium core of the panel balsawood [0035] 17, said balsawood being constructed and arranged to form the structural ribs and the center material for the panel, the roven mat and fiberglass material sheathing the balsawood core 15, and the entire assembly saturated and covered in a fiberglass resin 15-17, vertical ends having a frame rail with through holes 9 to facilitate engagement of panels to vertical end to vertical end via threaded fasteners, the panel having a horizontal top-line 3 at the top of the form and horizontal bottom-line on the bottom, the internal side of the panel not having protruding structural ribs is finished to a frictionless smooth finish facilitating easy removal from set concrete and simple brush and water clean up.
  • Referring to FIG. 4, describing the top view of the panel form system having the special top-line connector band [0036] 6 attaching the horizontal top-line 3 of the first panel to the second panel designating the width of the top of the concrete foundation or wall, the threaded fastener 4-5 removably engaged through the through hole 9 of the vertical edge 2 attaching the panels end to end, the top-line connector band inner punch hole 20 providing support and separation of the horizontal top-line of the panels, the bottom-line connector band 11 permanently attaching to the base/soil and interconnecting the horizontal bottom-line 4 of the panels
