Abstract
Abstract A housing module which is formed as a box-beam structure, and has sufficient rigidity and strength so that it can be used to span distances of relatively great length. The housing unit is able to be prefabricated and can be readily transported without the need for additional support or stiffening members to prevent damage from excess flexure. Further, the unit can be simply put in place on site without any additional stiffening or strengthing members. In addition, the units can be stacked one over the other, thus greatly increasing their flexibility to the architect.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
270 words
A box building module comprising a series of U-shaped stress members arranged in spaced serial order lengthwise of said module; each stress member comprising a horizontally positioned truss and a pair of vertically extending elements; said elements being positioned respectively at spaced locations along said truss and extending vertically along said truss and then above said truss a substantial distance; the portion of each of said elements positioned along one of said trusses being secured thereto in load transmitting manner; a horizontally extending vertically positioned sheath-like stress band extending along the full length of said series of stress members and secured in stress transmitting manner to said vertically extending elements thereof for a substantial portion of their vertical extent to form a rigid stress absorbing unitary side structure; said horizontally positioned sheath-like stress band being received within notched portions of said vertically extending elements of said stress members; said horizontally positioned stress band also being secured to the full height of said truss members at the connection thereto of said vertically extending elements of each of said U-shaped stress members; a sheath member extending vertically along the full length of said U-shaped stress members and being affixed to said horizontally extending sheath-like stress band for the full extent thereof and to said vertically extending element for the full extent thereof above said horizontally disposed sheath-like stress band; and an upper member joining said U-shaped stress members to form a roof means integrally connected to the upper ends of said U-shaped stress members and to form therewith a substantially rigid box-beam housing unit capable of spanning a substantial distance between supports.
Claim 2
Dependent Claim
270 words
A box building module comprising a series of U-shaped stress members arranged in spaced serial order lengthwise of said module; each stress member comprising a horizontally positioned truss and a pair of vertically extending elements; said elements being positioned respectively at spaced locations along said truss and extending vertically along said truss and then above said truss a substantial distance; the portion of each of said elements positioned along one of said trusses being secured thereto in load transmitting manner; a horizontally extending vertically positioned sheath-like stress band extending along the full length of said series of stress members and secured in stress transmitting manner to said vertically extending elements thereof for a substantial portion of their vertical extent to form a rigid stress absorbing unitary side structure; said horizontally positioned sheath-like stress band being received within notched portions of said vertically extending elements of said stress members; said horizontally positioned stress band also being secured to the full height of said truss members at the connection thereto of said vertically extending elements of each of said U-shaped stress members; a sheath member extending vertically along the full length of said U-shaped stress members and being affixed to said horizontally extending sheath-like stress band for the full extent thereof and to said vertically extending element for the full extent thereof above said horizontally disposed sheath-like stress band; and an upper member joining said U-shaped stress members to form a roof means integrally connected to the upper ends of said U-shaped stress members and to form therewith a substantially rigid box-beam housing unit capable of spanning a substantial distance between supports.
Claim 3
Dependent Claim
135 words
A box-beam housing module comprising: a series of substantially U-shaped stress members arranged in spaced serial order lengthwise of the structure of the module; each stress member comprising a horizontally positioned truss and a pair of vertically extending elements; said elements being positioned respectively at spaced locations along said truss, and extending vertically along said truss and then above said truss a substantial distance; the portion of each of said elements positioned along each one of said trusses being secured thereto in load transmitting manner; and a horizontally extending vertically positioned sheath-like stress band extending along the full length of said series of U-shaped stress members and secured in stress transmitting manner to said vertically extending elements thereof for a substantial portion of their vertical extent to form a rigid stress absorbing unitary side structure.
Claim 4
Dependent Claim
135 words
A box-beam housing module comprising: a series of substantially U-shaped stress members arranged in spaced serial order lengthwise of the structure of the module; each stress member comprising a horizontally positioned truss and a pair of vertically extending elements; said elements being positioned respectively at spaced locations along said truss, and extending vertically along said truss and then above said truss a substantial distance; the portion of each of said elements positioned along each one of said trusses being secured thereto in load transmitting manner; and a horizontally extending vertically positioned sheath-like stress band extending along the full length of said series of U-shaped stress members and secured in stress transmitting manner to said vertically extending elements thereof for a substantial portion of their vertical extent to form a rigid stress absorbing unitary side structure.
Claim 5
Dependent Claim
37 words
The structure of claim 2, wherein: said horizontally positioned sheath-like stress band is received within notched portions of said vertically extending elements of said stress members and extending from the lowermost ends thereof upwardly a substantial distance.
Claim 6
Dependent Claim
38 words
The structure of claim 3, wherein: said horizontally positioned stress band is also secured to the full height of said truss members at the connection thereto of said vertically extending elements of each of said U-shaped stress members.
Claim 7
Dependent Claim
54 words
The structure of claim 2, 3 or 4, including: additional longitudinally disposed sheath-like members forming extensions of said stress band positioned at the respective longitudinal ends of said structure, and each abutting said stress band thereat, and extending thereat upwardly to the full extent of the vertically extending elements of said U-shaped stress members.
Claim 8
Dependent Claim
57 words
The structure of claim 3 or 4, including: a sheath member extending vertically along the full length of said series of U-shaped stress members and being affixed to said horizontally extending sheath-like stress band for the full extent thereof and to said vertically extending elements for the full extent thereof above said horizontally disposed sheath-like stress band.
Claim 9
Dependent Claim
22 words
The structure of claim 6, wherein: said sheath member comprises vertically arranged tongue and groove members united to form a unitary sheath.
Claim 10
Dependent Claim
32 words
The structure of claim 6, including: an insulating sheath member extending over the full extent of said sheath member and secured thereto, and a decorative outer covering over said insulating sheath member.
Claim 11
Dependent Claim
38 words
The structure of claim 6, including: a roof comprising roof forming truss members extending horizontally above said vertical elements and horizontally across said module over opposed pairs of said vertically extending elements and being secured to the latter.
Claim 12
Dependent Claim
55 words
The structure of claim 9, wherein: said sheath member extends above said vertically extending elements of said U-shaped stress members and is secured to said roof forming truss members thereabove to form a single stress transmitting interconnection between said U-shaped stress members and said roof trusses as well as said horizontally positioned sheath-like stress band.
Claim 13
Dependent Claim
