Abstract
Abstract A method for forming a building concrete foundation including the steps of molding integral concrete main and partition footings, embedding metal molds into the main and partition footings while the concrete of the footings are in a partially solidified condition and after the solidification of the concrete, removing the molds from the footings to thereby form ventilation areas on the footings.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
134 words
A method for forming a wooden building foundation assembly including a concrete foundation provided on the top with a plurality of ventilation areas in spaced relationship along the length of the foundation and a wooden sill built on the concrete foundation, comprising the steps of placing concrete into a foundation mold to form the concrete foundation, forming pairs of opposing recesses on the top of the concrete foundation on the opposite sides of the foundation while the concrete is in a partially solidified condition with the two opposing recesses in each pair being positioned spaced from each other, forming an intermediate perforated communication wall between the opposing recesses of each pair during said step of forming pairs of opposing recesses, and building the wooden sill on the concrete foundation after solidification of the concrete.
Claim 2
Independent Claim
134 words
A method for forming a wooden building foundation assembly including a concrete foundation provided on the top with a plurality of ventilation areas in spaced relationship along the length of the foundation and a wooden sill built on the concrete foundation, comprising the steps of placing concrete into a foundation mold to form the concrete foundation, forming pairs of opposing recesses on the top of the concrete foundation on the opposite sides of the foundation while the concrete is in a partially solidified condition with the two opposing recesses in each pair being positioned spaced from each other, forming an intermediate perforated communication wall between the opposing recesses of each pair during said step of forming pairs of opposing recesses, and building the wooden sill on the concrete foundation after solidification of the concrete.
Claim 3
Dependent Claim
68 words
A method as in claim 1, wherein said steps of forming pairs of opposing recesses and an intermediate perforated communication wall include embedding substantially trapezoidally shaped metal moldings into the top of the concrete foundation on the opposite sides of the foundation while the concrete of the foundation is in its partially solidified condition and removing the metal molds from said foundation after a predetermined period of time.
Claim 4
Dependent Claim
89 words
A method as in claim 1, wherein the steps of forming pairs of opposing recesses and an intermediate perforated communication wall include embedding substantially trapezoidally shaped metal molds in the top of the concrete foundation on the opposite sides of the foundation while the concrete of said foundation is in its partially solidified condition, and simultaneously embedding a perforated communication board between the metal molds and then removing the metal molds from the concrete foundation after a predetermined period of time, leaving the perforated communication board in the foundation.
Claim 5
Dependent Claim
136 words
The method as in claim 1, wherein the steps of forming pairs of opposing recesses and an intermediate perforated communication wall include simultaneously embedding a substantially trapezoidally shaped metal mold having a plurality of projections on one side thereof and a substantially trapezoidally shaped metal mold having a plurality of through holes corresponding to the projections in number, shape and position into the top of the concrete foundation with the projections and through holes facing each other on the opposite sides of the foundation until the projections are received in the through holes while the concrete of the concrete foundation is in its partially solidified condition so as to form a perforated communication wall of concrete integrally with the concrete foundation, and removing the metal molds from the concrete foundation after a predetermined period of time.
Claim 6
Dependent Claim
76 words
The method as set forth in claim 1, wherein the step of forming pairs of opposing recesses and an intermediate perforated communication wall includes the step of forming a ventilation area by notching the concrete foundation on the opposite sides of the foundation to form notches extending a predetermined depth from the top and embedding a perforated communication board having a plurality of through holes into the concrete foundation in an intermediate position between the notches.
Claim 7
Dependent Claim
18 words
The method as set forth in claim 3, in which said perforated communication board is a plastic board.
Claim 8
Dependent Claim
18 words
The method as set forth in claim 5, in which said perforated communication board is a plastic board.
Claim 9
Independent Claim
175 words
A method for forming a wooden building foundation assembly including a concrete foundation provided on the top thereof with a plurality of ventilation areas in spaced relationship along the length of the foundation and a wooden sill built on the concrete foundation, comprising the steps of: (a) placing concrete into a foundation mold to form the concrete foundation; (b) simultaneously embedding a substantially trapezoidally shaped metal mold having a plurality of projections on one side thereof and a substantially trapezoidally shaped metal mold having a planar front face into the top of the concrete foundation with the projections extending to the planar front face, while the concrete of the concrete foundation is in a partially solidified condition so as to concurrently form opposing recesses in the foundation and an intermediate perforated communication wall of concrete between the opposing recesses of each pair during the step of embedding; (c) removing the metal molds from the concrete foundation after a predetermined time; and (d) building the wooden sill on the concrete foundation after solidification of the concrete.
Claim 10
Independent Claim
175 words
A method for forming a wooden building foundation assembly including a concrete foundation provided on the top thereof with a plurality of ventilation areas in spaced relationship along the length of the foundation and a wooden sill built on the concrete foundation, comprising the steps of: (a) placing concrete into a foundation mold to form the concrete foundation; (b) simultaneously embedding a substantially trapezoidally shaped metal mold having a plurality of projections on one side thereof and a substantially trapezoidally shaped metal mold having a planar front face into the top of the concrete foundation with the projections extending to the planar front face, while the concrete of the concrete foundation is in a partially solidified condition so as to concurrently form opposing recesses in the foundation and an intermediate perforated communication wall of concrete between the opposing recesses of each pair during the step of embedding; (c) removing the metal molds from the concrete foundation after a predetermined time; and (d) building the wooden sill on the concrete foundation after solidification of the concrete.
