Abstract
A concrete wall pre fabrication for the easy assembly of walls for residential and commercial buildings. More specifically, there is an apparatus and method for enabling the outer form of a concrete wall to be more precisely assembled off site and then transported to the work site and assembled the wall in the proper place with appropriate rebar before filling the forms with cement or concrete material as disclosed in the specification and drawings of the invention and the related claims. Additionally, there is a need for a form spacer that efficiently attaches between the form walls with a more precise use of glue and stronger attachment to the form walls.
Claims18
A pre fabricated concrete wall form, comprising:
- a. a first and second wall having a major surface facing each other;
- b. at least one wall spacer positioned between and coupling together the first and second wall, wherein the wall spacer includes:
- i. a top and bottom spacer wall, each having at least one hole formed in each;
- ii. a first and second side spacer wall, coupled to the respective first and second wall;
- iii. a first and second oppositely facing opening defined by the top, bottom, first and second side spacer walls;
- and
- iv. a central plate coupled within the top, bottom, first and second side spacer walls, wherein the central plate has a central plate hole;
- c. at least one vertical and horizontal rebar, where the vertical rebar extends between the first and second walls and through the one hole formed in each of the top and bottom spacer wall, and the horizontal rebar extending between the first and second walls and through the first and second oppositely facing opening and through the central plate hole;
- and
- d. a layer of concrete positioned between the first and second wall, and substantially filling the wall spacer through the first and second opening.
A method of assembling a pre fabricated concrete wall, comprising:
- a. providing a first and second wall having a major surface facing each other;
- b. positioning at least one wall spacer between and coupling together the first and second wall, wherein the wall spacer includes:
- i. a top and bottom spacer wall, each having at least one hole formed in each;
- ii. a first and second side spacer wall, coupled to the respective first and second wall;
- iii. a first and second oppositely facing opening defined by the top, bottom, first and second side spacer walls;
- and
- iv. a central plate coupled within the top, bottom, first and second side spacer walls, wherein the central plate has a central plate hole;
- c. placing at least one vertical and horizontal rebar within the wall spacer, where the vertical rebar extends between the first and second walls and through the one hole formed in each of the top and bottom spacer wall, and the horizontal rebar extending between the first and second walls and through the first and second oppositely facing opening and through the central plate hole;
- and
- d. poring a layer of concrete between the first and second wall, and substantially filling the wall spacer through the first and second opening.
A method of assembling a pre fabricated concrete wall, comprising:
- a. placing a first wall laid out in a horizontal position;
- b. placing glue on the first wall in at least one location;
- c. placing wall spacers over the glue;
- d. prepare a second wall by laying it horizontal, and applying glue to a respective matching location to that placed on the first wall;
- e. placing the second wall on the opposite side of the wall spacers so that the glue abuts to the wall spacer to form a wall section;
- f. drying the glue on the wall section;
- g. transporting the wall section to a building work site;
- h. providing a building with a foundation of concrete that was pored and formed with vertical rebar;
- i. lifting up and sliding the wall section over the vertical rebars to fit through holes located in the wall spacers;
- j. inserting horizontal rebars through second holes in the wall spacers;
- k. using a connector tab to couple adjoining wall sections;
- and
- l. poring cement between the first and second wall.
