Abstract
Abstract A prefabricated transportable room element for use in the erection of a building comprising a plurality of such room elements, said room element forming a load-bearing unit and comprising a load bearing frame or chassis consisting of a load-bearing floor panel structure and at least one load-bearing vertical structure, and at least one prefabricated, self-supporting cell unit incorporating such electrical, plumbing, gas and like installations as would normally be present in that region of a finished building, said unit being factory assembled with said load-bearing frame or chassis to form a room element ready for transport.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
109 words
A method of constructing a transportable prefabricated room element comprising: a. preparing a load-bearing floor panel structure providing a horizontal floor surface; b. preparing at least one load-bearing vertical structure; c. preparing at least one prefabricated self-supporting cell unit comprising a ceiling member and at least one full height wall member depending from the ceiling member, and d. assembling the prefabricated self-supporting cell unit and the load-bearing vertical structure to the floor panel structure by joining the depending wall member to the horizontal floor surface and joining the load-bearing vertical structure to the floor panel structure and to the cell unit at a factory remote from a building site.
Claim 2
Independent Claim
109 words
A method of constructing a transportable prefabricated room element comprising: a. preparing a load-bearing floor panel structure providing a horizontal floor surface; b. preparing at least one load-bearing vertical structure; c. preparing at least one prefabricated self-supporting cell unit comprising a ceiling member and at least one full height wall member depending from the ceiling member, and d. assembling the prefabricated self-supporting cell unit and the load-bearing vertical structure to the floor panel structure by joining the depending wall member to the horizontal floor surface and joining the load-bearing vertical structure to the floor panel structure and to the cell unit at a factory remote from a building site.
Claim 3
Dependent Claim
50 words
A method of constructing a transportable prefabricated room element according to claim 1 including the step of joining the depending wall member to the horizontal floor surface by mounting a channel member on the floor surface and inserting the lower end of the depending wall member into the channel member.
Claim 4
Dependent Claim
38 words
A method of constructing a transportable prefabricated room element according to claim 2 including the step of inserting a sealing material into the channel member before inserting the lower end of the wall member into the channel member.
Claim 5
Dependent Claim
57 words
A method of constructing a transportable prefabricated room element according to claim 1 wherein the ceiling member of the cell unit is formed with at least one passage and including the step of joining the cell unit to the load-bearing vertical structure by inserting a post-tensioning member through the passage and connecting it to the vertical structure.
Claim 6
Dependent Claim
44 words
A method of constructing a transportable prefabricated room element according to claim 1 including the step of preparing the prefabricated self-supporting cell unit by casting a fireproof castable building material in a mold to produce a cell unit having integral wall and ceiling members.
Claim 7
Dependent Claim
48 words
A method of constructing a transportable prefabricated room element according to claim 1 including the step of assembling a plurality of self-supporting cell units and two load-bearing vertical structures to the floor panel with the cell units disposed in laterally abutting relation between the two vertical load-bearing sructures.
Claim 8
Independent Claim
145 words
A method of constructing a building from a plurality of transportable prefabricated room elements comprising prefabricating each of a plurality of room elements by: a. preparing a load-bearing floor panel structure providing a horizontal floor surface; b. preparing at least one load-bearing vertical structure; c. preparing at least one prefabricated self-supporting cell unit comprising a ceiling member and at least one full height wall member depending from the ceiling member; d. assembling the prefabricated self-supporting cell unit and the load-bearing vertical structure to the floor panel structure by joining the depending wall member to the horizontal floor surface and joining the load-bearing vertical structure to the floor panel structure and to the cell unit at a factory remote from a building site; e. transporting the plurality of room elements to a building site, and f. mounting the elements in face-to-face relation to form a building.
Claim 9
Independent Claim
145 words
A method of constructing a building from a plurality of transportable prefabricated room elements comprising prefabricating each of a plurality of room elements by: a. preparing a load-bearing floor panel structure providing a horizontal floor surface; b. preparing at least one load-bearing vertical structure; c. preparing at least one prefabricated self-supporting cell unit comprising a ceiling member and at least one full height wall member depending from the ceiling member; d. assembling the prefabricated self-supporting cell unit and the load-bearing vertical structure to the floor panel structure by joining the depending wall member to the horizontal floor surface and joining the load-bearing vertical structure to the floor panel structure and to the cell unit at a factory remote from a building site; e. transporting the plurality of room elements to a building site, and f. mounting the elements in face-to-face relation to form a building.
Claim 10
Dependent Claim
48 words
A method of constructing a building according to claim 7 including the step of mounting some of the plurality of room elements with their vertical load-bearing structures vertically aligned with and in supporting relation to the vertical load-bearing structures of other room elements to form a multistorey building.
