Abstract
Abstract A foundation for a wooden building and a method of constructing the foundation are disclosed, which foundation comprises (a) a concrete foundation footing supporting foundation walls thereon, which foundation walls support the outer walls and inner walls of a wooden building thereon, (b) a plurality of concrete blocks which are integrally jointed, provided continuously along the inside portion of the foundation walls on the concrete foundation footings, (c) a vaporproof sheet material which entirely and tightly covers at least the inside of the integrally jointed concrete blocks and the outer surface of the fill formed in the areas inside the concrete blocks, and (d) a concrete floor portion which is deposited integrally with the foundation walls and the concrete blocks so as to cover the vaporproof material which covers the inside of the integrally jointed concrete blocks and the outer surface of the fill.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
133 words
A foundation for wooden buildings, comprising: (a) underground concrete foundation footings supporting foundation walls thereon, which foundation walls support the outer walls and inner walls of a wooden building thereon, (b) a plurality of concrete blocks which are integrally jointed, provided continuously along the inside portion of said foundation walls and on said concrete foundation footings, (c) a vaporproof sheet material which entirely and tightly covers at least the inside of said integrally jointed concrete blocks and the outer surface of the fill formed in the areas inside said concrete blocks, and (d) a concrete floor portion which is cast integrally with said foundation walls and said concrete blocks so as to cover said vaporproof material which covers the inside of said integrally jointed concrete blocks and the outer surface of the fill.
Claim 2
Dependent Claim
133 words
A foundation for wooden buildings, comprising: (a) underground concrete foundation footings supporting foundation walls thereon, which foundation walls support the outer walls and inner walls of a wooden building thereon, (b) a plurality of concrete blocks which are integrally jointed, provided continuously along the inside portion of said foundation walls and on said concrete foundation footings, (c) a vaporproof sheet material which entirely and tightly covers at least the inside of said integrally jointed concrete blocks and the outer surface of the fill formed in the areas inside said concrete blocks, and (d) a concrete floor portion which is cast integrally with said foundation walls and said concrete blocks so as to cover said vaporproof material which covers the inside of said integrally jointed concrete blocks and the outer surface of the fill.
Claim 3
Dependent Claim
25 words
The foundation for wooden buildings as claimed in claim 1, wherein the lower portion of said floor portion is in the shape of an arch.
Claim 4
Dependent Claim
25 words
The foundation for wooden buildings as claimed in claim 1, wherein said vaporproof sheet material extends onto the bottom surface of said concrete foundation footings.
Claim 5
Dependent Claim
154 words
A construction method of constructing a foundation for wooden buildings comprising the steps of: (1) pouring concrete for underground concrete footings, which support thereon foundation walls, (2) placing concrete blocks integrally and continuously on said concrete footings at the locations corresponding to the inside of said foundation walls to be formed on said concrete footings prior to the complete setting of said concrete footings, (3) providing forms only at the locations corresponding to the outside of said foundation walls to be formed, opposite to said concrete blocks, (4) tightly covering the inside surfaces of said concrete blocks with a vaporproof sheet material, (5) carrying out back filling in the areas inside said concrete blocks to form fill therein, (6) extending said vaporproof sheet material so as to tightly cover said fill, and (7) pouring concrete entirely in the area surrounded by said forms to form said foundation wall and a concrete floor portion integrally.
Claim 6
Dependent Claim
154 words
