Abstract

An insulated load bearing wall (10, 10'"'"') comprising panels of extruded polymer foam (20, 22, 50, 52, 54, 56) into which tubular, load carrying frame members (12, 14, 48) have been incorporated. A tongue is formed at one vertical edge of each panel (10, 10'"'"') and a groove is formed at the opposite vertical edge. The tubular frame members (12, 14, 48) are bonded to the extruded polymer foam.

Claims

1. An insulated wall section having first and second vertical edges, comprising:

a plurality of tubular metal, outside frame members and a plurality of tubular metal, inside metal frame members, said outside frame members being spaced apart on the outside of the wall and the inside frame members being spaced apart on the inside of the wall;

metal angle frame members extending along the upper and lower corners of the wall section;

a core of extruded polymer foam which has a thickness substantially equal to the distance between the inside and outside tubular frame members, and

inside and outside panels of extruded polymer foam, each having a thickness substantially equal to the thickness of the metal frame members.

said core extending between the inside and outside tubular metal frame members in the thickness direction of the wall, said panels of extruded polymer foam extending from the metal frame members in the width direction of the wall, and outwardly bounding the core,.

said panels and said core being staggered in the width direction of the wall to form a tongue at the first vertical edge of the wall section formed by a projecting portion of the core and a groove at the second vertical edge of the wall section formed by and between projecting portions of said inside and outside panels;

said tubular metal frame members being intermediate in the wall section of the tongue and the groove, and said core and said panels being bonded to each other and to the tubular metal frame members.

2. A wall according to claim 1, further comprising an insulated upper plate member on top of the wall, said insulated upper plate member having a rectangular cross sectional shape and comprising inside and outside elongated wood members and a bar of insulating material sandwiched between and bonded to the wood members, to form a thermal break.

3. An insulated roof section having first and second edges, comprising:

a plurality of tubular metal, outside frame members, and a plurality of tubular metal, inside frame members, said outside frame members bring spaced apart on the outside of the roof and the inside frame members being spaced apart on the inside of the roof section;

a core of extruded polymer foam which has a thickness substantially equal to the distance between the inside and outside tubular frame members;

inside and outside panels of extruded polymer foam, each having a thickness substantially equal to the thickness of the metal frame members,

said core extending between the inside and outside metal frame members in the thickness dimension of the roof, and

said panels of extruded polymer foam extending from the metal frame members in the width direction of the roof, and outwardly bounding the core material, said panels and said core being staggered in the width direction of the roof section such that a tongue is formed at the first edge and a complementary groove is formed at the second edge, said tongue being formed by a projecting portion of the core and said groove being formed by and between projecting portions of said inside and outside panels;

said tubular metal frame members being intermediate in the roof section of the tongue and the groove, and said core and said panels being bonded to each other and to the tubular metal frame members.
