  • the present disclosure relates to concrete form systems and devices, and related methods. More specifically, the present disclosure relates to concrete form systems and devices, and related methods that can be used to form structural concrete floors, or flat to slightly pitched roofs.
  • Concrete is frequently used in the construction industry. For instance, concrete is commonly used in various aspects of building construction, including to form foundations, floors, ceiling, roofs, and walls. In such applications, cast-in-place concrete is frequently used. Concrete can be poured into a form and held in place by the form while the concrete cures. Once the concrete has sufficiently cured, the form may be removed or stripped from the concrete. This may include removing any bracing and form members.
  • concrete can have relatively low insulative properties (i.e., relatively low R-value), that make it difficult to efficiently control the climate within the building. For instance, it may be difficult to maintain different levels of a building at desired temperatures because heat from lower levels may rise through the concrete floors/ceilings to upper floors.

  • Figure 1 illustrates an example embodiment of a concrete form system 100 that may be used to construct a structurally sound concrete floor or flat to slightly pitched roof in a building.
  • the form system 100 includes a plurality of concrete forms 102. While discussed in greater detail below, the concrete forms 102 may be positioned adjacent and/or secured to one another to create a concrete form of a desired size (e.g., the size of the concrete floor that is being formed).

With the support of the temporary shoring elements 104, the roll bucks 106 can provide additional structural support to the concrete forms 102 while concrete is poured thereon and while the concrete cures.
  • the temporary shoring elements 104 and the roll bucks 106 may be removed, leaving in place the concrete forms 102 and the cured concrete.
  • various components may be secured to or within the underside of the concrete forms 102. For instance, HVAC ductwork, plumbing pipes, electrical conduits, etc. may be attached to or run through the concrete forms 102. Additional details regarding this aspect of the concrete form system 100 will be provided below.
  • Figures 2-6 illustrate perspective, end, side, top, and bottom views, respectively, of a concrete form 102 apart from the rest of the system 100.

  • connection feature 118a on one concrete form 102 may mate with the connection features 118b on an adjacent concrete form 102, as illustrated in Figure 1.
  • connection features 118a, 118b may facilitate a secure temporary or permanent connection between adjacent concrete forms 102.
  • the connection features 118a, 118b may facilitate alignment between adjacent concrete forms 102 when the concrete form system 100 is being assembled.
  • the connection features 118a, 118b may facilitate both alignment and secure connections between adjacent concrete forms 102.

  • one of the support columns 110a, 110b may include one or more apertures 122 while the other support column may not include apertures 122 (or not the same number of apertures 122).
  • each of the support columns 110a, 110b includes one or more apertures 124 that extend (vertically) therethrough between the channels 116a, 116b and the lower ends of the support columns 110a, 110b. Additionally, as shown in Figures 2, 3, and 6, each of the support columns 110a, 110b may have a channel 126 formed in a lower end thereof. The channels 126 may be recessed from the lower ends of the support columns 110a, 110b and may extend along all or a portion of the length of the support columns 110a, 110b. The purpose and functionality of the apertures 124 and channels 126 will be described below in connection with Figures 8 and 9.

The concrete fills the channels 116a, 116b. When cured, the concrete in the channels 116a, 116b may act as floor joists or beams. To provide the floor joists or beams sufficient strength, rebar or other reinforcement elements can be disposed within the channels 116a, 116b prior to pouring the concrete. To properly position the rebar within the channels 116a, 116b, a rebar tree as shown in Figure 7 and/or Figures 8A-8C may be used.
