Abstract
Abstract This invention relates to a cast monolithic house and to a method for casting, simultaneously, the roof, end wall and sidewalls thereof at the site. The method involves hinging together roof and sidewall forming portions of a form and lifting such form into place by wheeled carriers which are guided by jigs on the floor of the house. Jacks, mounted on the wheeled carriers, will lift the form into place. Wall form positioning linkage is connected between the wheeled carriers and the sidewall forming portions of the form to retract or expand them into normal vertical position in wedging relationship with floor bucks serving as base portions of said sidewall forming portions.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
191 words
The method of simultaneously forming a slanted roof and two vertical sidewalls of a building at the site to form a monolithic structure, comprising pivotally interconnecting a roof portion, comprising lowermost and uppermost pivotal sections, and a sidewall portion of a first interior form, raising said roof portion of said form vertically until said lowermost section is in place while said sidewall portion is partially retracted from a molding position and while said uppermost roof section is pivotally and downwardly retracted, thereafter pivotally moving said sidewall portion toward a vertical position and pivotally lifting said uppermost section of said roof portion of said form into close confronting relationship with a like uppermost section of an adjacent and like second interior form, said uppermost sections of both said roof portions being adapted to form the apex of said building, and pouring concrete between said sidewall forms and cooperating spaced sidewall forms and onto the roof portions of said interior forms, the roof portions of said interior forms having roof edge forms attached thereto to control the thickness of the concrete and to be used as a screed surface for finishing the roof.
Claim 2
Independent Claim
191 words
The method of simultaneously forming a slanted roof and two vertical sidewalls of a building at the site to form a monolithic structure, comprising pivotally interconnecting a roof portion, comprising lowermost and uppermost pivotal sections, and a sidewall portion of a first interior form, raising said roof portion of said form vertically until said lowermost section is in place while said sidewall portion is partially retracted from a molding position and while said uppermost roof section is pivotally and downwardly retracted, thereafter pivotally moving said sidewall portion toward a vertical position and pivotally lifting said uppermost section of said roof portion of said form into close confronting relationship with a like uppermost section of an adjacent and like second interior form, said uppermost sections of both said roof portions being adapted to form the apex of said building, and pouring concrete between said sidewall forms and cooperating spaced sidewall forms and onto the roof portions of said interior forms, the roof portions of said interior forms having roof edge forms attached thereto to control the thickness of the concrete and to be used as a screed surface for finishing the roof.
Claim 3
Dependent Claim
15 words
The method recited in claim 1 including the step of screeding said concrete roof portions.
Claim 4
Dependent Claim
54 words
The method recited in claim 1 wherein said interior forms are each mounted on a wheeled carrier and are initially wheeled into place within the building to be constructed, and wherein said retracting movements and movements to a vertical position of said sidewalls are effected by jacking movements between said sidewalls and said carriers.
Claim 5
Dependent Claim
27 words
The method recited in claim 1 including a step of forming an end wall simultaneously with said sidewalls by pouring concrete between spaced cooperating end wall forms.
Claim 6
Dependent Claim
21 words
The method recited in claim 1 including moving said uppermost sections into close confronting relationship by abutting their free ends together.
Claim 7
Dependent Claim
32 words
The method recited in claim 1 wherein forming said close confronting relationship of said uppermost sections comprises abutting their free ends against a stationary post immediately below the apex of the roof.
