Abstract
Abstract This invention relates to a cast monolithic house and to a apparatus 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. An acme thread with a jam nut mounted on the wheeled carriers, will lift the form into place. While a base slab is poured, a curb-approximately 3 inch X 3 inch is cast above the floor to act as a stop for the interior forming section and to control the thickness of the wall, as well as acting as a seal.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
228 words
A form assembly for simultaneously casting a pair of roof and sidewall portions of a building to form a monolithic structure, comprising a pair of side by side wheeled, rectangular carriers, each carrier having two corner posts located at the corners farthest from the other carrier and two corner posts of greater height located at opposite corners of the carrier, jacking means connected to each of said corner posts, a pair of interior forms, each supported by one of said carriers and including a roof forming portion supported on the corner posts of the corresponding carrier in slanted position to enable lifting and lowering of said roof forming portion and a sidewall forming portion pivotally connected to one end of said roof forming portion suspended in substantially vertical position, each of said roof forming portions having a pivotal extension means whose end is located substantially at the apex formed by the side by side roof forming portions, means for bridging and supporting said ends of said pivotal extension means is confronting relationship, a second jacking means extending laterally from the lower side portion of each carrier and pivotally connected to the adjacent interior sidewall forming portion to enable pivotal movement of said sidewall forming portion away from a vertical position after casting of the sidewall, and a pair of vertical exterior forms spaced from said sidewall forming portions.
Claim 2
Dependent Claim
228 words
A form assembly for simultaneously casting a pair of roof and sidewall portions of a building to form a monolithic structure, comprising a pair of side by side wheeled, rectangular carriers, each carrier having two corner posts located at the corners farthest from the other carrier and two corner posts of greater height located at opposite corners of the carrier, jacking means connected to each of said corner posts, a pair of interior forms, each supported by one of said carriers and including a roof forming portion supported on the corner posts of the corresponding carrier in slanted position to enable lifting and lowering of said roof forming portion and a sidewall forming portion pivotally connected to one end of said roof forming portion suspended in substantially vertical position, each of said roof forming portions having a pivotal extension means whose end is located substantially at the apex formed by the side by side roof forming portions, means for bridging and supporting said ends of said pivotal extension means is confronting relationship, a second jacking means extending laterally from the lower side portion of each carrier and pivotally connected to the adjacent interior sidewall forming portion to enable pivotal movement of said sidewall forming portion away from a vertical position after casting of the sidewall, and a pair of vertical exterior forms spaced from said sidewall forming portions.
Claim 3
Dependent Claim
44 words
A form assembly as recited in claim 1 wherein each of said vertical exterior forms comprises a top pivotal section and mechanical means connected therebetween to enable pivoting of said top pivotal section to form selective eave angles relative to the roof forming portions.
Claim 4
Dependent Claim
63 words
A form assembly as recited in claim 1 together with a concrete floor on which said carriers are supported, and a concrete stop element integrally cast with said floor and extending about the perimeter of the floor in spaced relationship with said vertical exterior forms to limit pivotal outward movement of said interior sidewall forming portions to confine them to a vertical position.
Claim 5
Dependent Claim
49 words
A form assembly as recited in claim 1 together with a horizontally extending frame element located underneath and parallel to the apex formed by the side by side roof forming portions and against which said ends of said extension means of the roof forming portions are abutted before casting.
Claim 6
Dependent Claim
45 words
A form assembly as recited in claim 2 wherein said interior roof forming portions are each in the form of a grid surrounded by upstanding end wall portions, whereby the roof may be cast and screeded without the necessity of exterior roof forming form portions.
Claim 7
Dependent Claim
57 words
A form assembly as recited in claim 2 wherein said building is a two story building and wherein each sidewall forming portion includes means for forming horizontally extending, spaced, confronting grooves formed substantially centrally between the top and bottom of the cast sidewalls, said grooves adapted to support means for casting a concrete floor between said grooves.
Claim 8
Dependent Claim
51 words
A form assembly as recited in claim 2 together with an interior end wall forming portion carried by the corresponding carrier, and an exterior end wall forming portion spaced therefrom whereby an end wall will also be simultaneously cast to form a monolithic structure including sidewalls, roof and an end wall.
Claim 9
Dependent Claim
16 words
A form assembly as recited in claim 1 wherein said wheeled carriers include swivelly mounted wheels.
