Definitions

  • the present invention relates generally to constructing concrete structures, which typically employ filler material to reduce the amount of concrete necessary for the construction of concrete elements.
  • a filler is often mixed into the wet concrete to reduce the weight of the concrete elements by reducing the volume of concrete necessary to construct the concrete elements.
  • An example of such a filler is Styrofoam.
  • a method of reducing the volume of concrete necessary for constructing a concrete element includes the steps of providing a plurality of filler elements and a wire assembly, coupling each of the plurality of filler elements to the wire assembly, disposing the wire assembly into a concrete element form, and filling the concrete element form with concrete for producing the concrete element with the wire assembly and coupled plurality of filler elements embedded therein.
  • the invention is also directed to a concrete element having a reduced volume of concrete.
  • the concrete element includes concrete, a wire assembly, and a plurality of filler elements coupled to the wire assembly such that the wire assembly and the coupled plurality of filler elements are embedded in the concrete element, thereby reducing the volume of concrete required to form the concrete element .

  • the present invention involves a method for using a plurality of filling elements, such as empty (e.g. , used, etc.) , plastic bottles or cans to reduce the volume of concrete necessary for the construction of concrete elements, such as concrete walls, floors, and ceiling slabs, and thereby also reduce the weight of the concrete elements .
  • a plurality of filling elements such as empty (e.g. , used, etc.) , plastic bottles or cans to reduce the volume of concrete necessary for the construction of concrete elements, such as concrete walls, floors, and ceiling slabs, and thereby also reduce the weight of the concrete elements .
  • an empty (i.e. , used) plastic bottle 102 e.g. , empty water, soda, or juice bottle
  • One end of an attachment wire 110 is wrapped around an existing threaded portion 106 of the bottle 102 where a cap is typically secured.
  • the bottle 102 is then closed/sealed with its corresponding cap 104, or some other plug such that the one end of the attachment wire 110 is secured between the threading or a top ridge 106, and the cap 104.
  • the attachment wire 110 is a flexible braided wire made of stainless steel.
  • an attachment hook 115 is coupled to the cap 104 using various methods known in the art .
  • a plurality of the plastic bottles 102 are attached/coupled to a 6'x 6' wire assembly 208 by a second end of the attachment wires 110 (or by the attachment hooks 115) .
  • the wire assembly 202 includes a wire mesh 202 supported and reinforced at appropriate points known to those skilled in the art with support or reinforcing bars 204.
  • the wire mesh 202 is made of stainless steel, and the reinforcing bars 204 are made of stainless steel or rebar.
  • one or more wire assemblies 208 (including the bottles 102) , are placed into a concrete element form or mold 300 through an opening 312 prior to the addition of wet concrete into the form 300.
  • wet concrete 310 is pumped through a port 302 in the bottom of the form 300 via a hose 304.
  • the bottles "float" but remain tethered to the wire assembly 208 by the wires 110.
  • the port 302 is sealed and the concrete is allowed to harden with the wire assembly 208 and plurality of plastic bottles 102 embedded therein. Thereafter, corrosion of the attachment wires 110 or the attachment hooks 115 is of no concern because the bottles are secured by the hardened concrete .
  • the plurality of plastic bottles 102 attached to the wire assembly 208 serve as a filler in the concrete element form 300 so that the amount of concrete needed to fill the concrete element form 300 is reduced.
  • the volume of concrete is reduced by the cumulative volume of the plurality of plastic bottles 102 and the wire assembly 208. Further, because less concrete is used, the resultant weight (and cost) of the completed concrete element is reduced.
  • the plastic bottles 102 help keep the wire assembly 608 in a specific position embedded within the concrete element 300 while the concrete hardens.
  • Benefits of the above-described invention include using less energy consuming concrete, reducing fuel consumed during transport of the concrete elements because of concrete elements' reduced weight, and reusing empty plastic bottles without expending energy for recycling or contributing to land fills.
  • the invention involves a method for a plurality of filling elements, such as empty (e.g., used, etc.) aluminum cans to reduce the volume of concrete necessary for the construction of concrete elements, such as concrete walls, floors, and ceiling slabs, and thereby also reduce the weight of the concrete elements.

  • a narrow slit 404 is cut along the length of the empty aluminum can 402 and approximately halfway through the top surface 406 and the bottom surface (not shown) of the empty aluminum can 402. The width of the slit 404 needs to be sufficient to allow mounting of the empty aluminum cans 402 in the manner described below.
  • the slit 404 preferably, has a width of between 3/16" and 1/4" .

  • the wire mesh 502 is made of stainless steel, and the reinforcing bars 506 are made of stainless steel or rebar.
  • a securing means such as a clip 509, tape, glue, epoxy, or other filler material for closing the slit 404 (see Fig. 1) is attached over each of the slits 404 to cover the slit 404 and prevent the wires 504 from sliding out of the slits 404 to disengage the empty aluminum cans 402 from the wire assembly 508.
  • the slit empty aluminum cans 402 are filled with liquid plastic, which is allowed to harden to secure the slit empty aluminum cans 402 to the wire assembly 508.

  • the aluminum cut from the cans 402 to make the slits 404 is also mixed into the wet concrete and used as filler. It is noted that because of the viscosity of the wet concrete and the surface area of each of the plurality of aluminum cans 402, the aluminum cans 402 help keep the wire assembly 508 in a specific position embedded within the concrete element while the concrete hardens .
  • each of the plurality of aluminum cans 402 comprises a pull tab 700, and each is attached to the wire assembly 508 via an attachment wire or hook 702 connected between the pull tabs and the wire assembly 508.
