## Abstract

A self-supporting roof for buildings, composed of modular elements each comprising an outer wall, a layer of heat insulating material, an inner wall carried by the outer wall and of the same form to support the insulating layer, and stiffening frame members secured to the outer wall wherein the inner wall is also rigidly secured to said frame members so as to form with the outer wall a unitary structure vis-a-vis the efforts.

## Claims

### Claim 1

A self-supporting roof for buildings composed of modular elements each comprising a longitudinally extending outer wall and an inner wall extending parallel with respect to each other, stiffening frame members disposed between said walls at spaced intervals and fixed to said walls to form a unitary structure, thermal insulating material disposed between said walls and supported by said inner wall, said stiffening frame members comprising spaced sections fixed respectively to said inner and outer walls and being in the form of irons having diverging flanges, spacer pads made of insulating material fixed at intervals between said irons, clamping members positioned on either side of said pads against the outside of said flanges and means to fasten said clamping members together to clamp said flanges and irons therebetween.

### Claim 2 (depends on 1)

A roof as claimed in claim 1, wherein the walls are curved ribbed sheets and the frame members are in the form of arcs.
