Abstract

Abstract In a dwelling construction system, a multi-story, multi-family building comprises prestressed concrete pallets which are supported between load bearing walls to form the floors and the ceilings of individual dwellings. Each dwelling includes a service core comprising an enclosure formed on one of the pallets and complete mechanicals for the dwelling. The service cores are fabricated by mass production techniques and are subsequently transported to the building site for installation. In some instances the service core comprises a complete dwelling, in which case the enclosure of the service core may form the exterior walls and the roof of the dwelling.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 112 words
A mobile home comprising: an elongated prestressed concrete pallet including a substantially planar deck and a plurality of reinforced, longitudinally extending tensioned beams depending from the deck, said beams being adapted for support only at or near one or more longitudinally spaced optimum load support points on said beams, an enclosure formed on the deck of the pallet including load bearing walls extending a predetermined distance above the deck to support an overhead structure; at least one pair of ground engaging wheels mounted on the under surface of the beams substantially at one or more of said optimum load support points; and connecting means for attaching said pallet to a towing vehicle.
Claim 2
Dependent Claim 112 words
A mobile home comprising: an elongated prestressed concrete pallet including a substantially planar deck and a plurality of reinforced, longitudinally extending tensioned beams depending from the deck, said beams being adapted for support only at or near one or more longitudinally spaced optimum load support points on said beams, an enclosure formed on the deck of the pallet including load bearing walls extending a predetermined distance above the deck to support an overhead structure; at least one pair of ground engaging wheels mounted on the under surface of the beams substantially at one or more of said optimum load support points; and connecting means for attaching said pallet to a towing vehicle.
Claim 3
Dependent Claim 53 words
The mobile home of claim 1 and further comprising means for securing said wheels to said beams, including reaction transmitting means cast integrally with certain of said reinforced beams and positioned at one or more of said spaced support points on the beams, and means connecting said wheels to said reaction transmitting means.
Claim 4
Dependent Claim 32 words
The mobile home of claim 1 wherein said pallet is supported by the connecting means and one or more pairs of ground engaging wheels located substantially at one optimum load support point.
Claim 5
Dependent Claim 29 words
The mobile home of claim 3 wherein said pallet is cantilevered over said load support point to extend substantially beyond said load support point away from said connecting means.
Claim 6
Dependent Claim 229 words
A transportable service module adapted to be towed to a construction site and placed into a total modular housing structure, said module comprising: a. a precast, prestressed concrete pallet having a deck and a plurality of reinforced longitudinally extending tensioned beams depending from the deck for prestressing said pallet, said beams having spaced support points for supporting a load on the deck; b. a framed structure including load bearing wall members mounted on said deck; c. an overhead structure supported on said load bearing wall members and together with said wall members enclosing a portion of the deck; d. a plurality of subenclosures within said framed structure for enclosing sanitary, electrical and mechanical services for said total modular housing structure; e. ground engaging wheels for transporting said service module; f. means for detachably sEcuring said ground engaging wheels to said service module including: i. reaction transmitting means cast integrally with certain of said reinforced beams and positioned at one or more of said spaced support points on the beams; ii. means detachably connecting said ground engaging wheels to said reaction transmitting means; g. draft means including a king pin for connecting said pallet to a fifth wheel of a towing vehicle including: i. draft reaction transmitting means cast integrally with certain of said reinforced beams; ii. means detachably connecting said king pin supporting means to said draft transmitting means.
Claim 7
Dependent Claim 229 words
A transportable service module adapted to be towed to a construction site and placed into a total modular housing structure, said module comprising: a. a precast, prestressed concrete pallet having a deck and a plurality of reinforced longitudinally extending tensioned beams depending from the deck for prestressing said pallet, said beams having spaced support points for supporting a load on the deck; b. a framed structure including load bearing wall members mounted on said deck; c. an overhead structure supported on said load bearing wall members and together with said wall members enclosing a portion of the deck; d. a plurality of subenclosures within said framed structure for enclosing sanitary, electrical and mechanical services for said total modular housing structure; e. ground engaging wheels for transporting said service module; f. means for detachably sEcuring said ground engaging wheels to said service module including: i. reaction transmitting means cast integrally with certain of said reinforced beams and positioned at one or more of said spaced support points on the beams; ii. means detachably connecting said ground engaging wheels to said reaction transmitting means; g. draft means including a king pin for connecting said pallet to a fifth wheel of a towing vehicle including: i. draft reaction transmitting means cast integrally with certain of said reinforced beams; ii. means detachably connecting said king pin supporting means to said draft transmitting means.
Claim 8
Dependent Claim 187 words
A transportable housing module comprising: a. a precast, prestressed concrete pallet and having a deck and a plurality of depending reinforced longitudinally extending tensioned beams for prestressing said pallet, said beams having spaced support points for supporting a load on the deck; b. a framed structure secured to said slab and enclosing the area thereof; c. an overhead structure supported on said framed structure; d. a plurality of subenclosures within said framed structure including subenclosures for sanitary, electrical and mechanical services; e. ground engaging wheels for transporting said housing module; f. means for securing said ground engaging wheels to said module including: i. reaction transmitting means cast integrally with certain of said reinforced beams and positioned substantially at one or more of said spaced support points on the beams; ii. means connecting said ground engaging wheels to said reaction transmitting means; g. draft means including a king pin for connecting said pallet to a fifth wheel of a towing vehicle including: i. draft reaction trasmitting means cast integrally with certain of said reinforced beams; ii. means connecting said king pin supporting means to said draft transmitting means.
Claim 9
Dependent Claim 187 words
A transportable housing module comprising: a. a precast, prestressed concrete pallet and having a deck and a plurality of depending reinforced longitudinally extending tensioned beams for prestressing said pallet, said beams having spaced support points for supporting a load on the deck; b. a framed structure secured to said slab and enclosing the area thereof; c. an overhead structure supported on said framed structure; d. a plurality of subenclosures within said framed structure including subenclosures for sanitary, electrical and mechanical services; e. ground engaging wheels for transporting said housing module; f. means for securing said ground engaging wheels to said module including: i. reaction transmitting means cast integrally with certain of said reinforced beams and positioned substantially at one or more of said spaced support points on the beams; ii. means connecting said ground engaging wheels to said reaction transmitting means; g. draft means including a king pin for connecting said pallet to a fifth wheel of a towing vehicle including: i. draft reaction trasmitting means cast integrally with certain of said reinforced beams; ii. means connecting said king pin supporting means to said draft transmitting means.
