Abstract

A rectilinear composite building panel having a pair of opposed faces, and a pair of opposed sides, the panel comprising a pair of spaced-apart rigid face sheets (56), a rigid insulating material (58) sandwiched between, and adhering to, the face sheets, connecting means (60) connecting the face sheets together to resist relative movement between the face sheets in the plane of the panel and out of the plane of the panel; the opposed sides (66,70) each have a profiled shape for mating with a correspondingly profiled side of an adjacent panel; each side (66,70) has means (72,74) for securing, or being secured to, a side of an adjacent panel of the same general construction. The panels can be easily assembled together to form a fire-resistant multi-story building.

Claims

1. A rectilinear composite load-bearing building panel for building structural load-bearing walls of permanent buildings, having a pair of opposed faces, a top surface, a pair of opposed sides and a bottom surface, the panel comprising a pair of spaced-apart rigid face boards of thermally non-conductive, fire resistant material, a rigid insulating material sandwiched between, and adhering to the face boards to form a composite structure capable of withstanding compressive forces between the top surface and the bottom surface of at least 5 kN per meter length of the panel, connecting means secured to the pair of the face boards and connecting the face boards together to resist relative movement between the face boards in the plane of the panel and out of the plane of the panel and wherein the opposed sides each have a profiled shape for mating with a correspondingly profiled side of an adjacent panel and wherein the sides have securing means for securing them to sides of adjacent panels.

2. A panel as claimed in claim 1, wherein the face boards are selected from the group consisting of particle boards, cement particle boards, glass fiber reinforced cement boards, cellulose reinforced gypsum boards, crushed slate boards and resin boards.

3. A panel as claimed in claim 1, wherein the insulating material is an organic foam.

4. A panel as claimed in claim 3, wherein the foam is a polyurethane.

5. A panel as claimed in claim 3, wherein the foam is formed in situ between the face boards and materials used are such that the foam adheres directly to a face board.

6. A panel as claimed in claim 3, wherein the face boards are cement particle boards and the foam is a polyurethane foam.

7. A panel as claimed in claim 1, wherein the connecting means is an elongate member extending vertically in the panel and is secured to the face boards.

8. A panel as claimed in claim 1, wherein the connecting means are spaced inwardly of the opposed sides.

9. A panel as claimed in claim 1, wherein the connecting means is a stud extending through the panel.

10. A panel as claimed in claim 1, wherein the connecting means is spaced inwardly of the securing means and wherein the securing means is not secured to the connecting means.

11. A permanent building comprising a foundation, a plurality of walls enclosing a space within the building, the walls being formed at least partially from panels as claimed in claim 1 whose opposed sides are secured together, means secured to the foundation for holding bases of the panels, means for holding tops of the panels and a roof structure supported on the walls, wherein the walls made of said panels form at least part of a structural frame of the building.

12. A building as claimed in claim 11, which is single storey.

13. A building as claimed in claim 11, which is multistorey and wherein each storey is formed by a row of panels as claimed in claim 16.

14. A building as claimed in claim 11, wherein internal walls of the panels are clad with a fire-resistant material.

15. A kit for forming a building, the kit comprising a plurality of panels as defined in claim 1 that can be secured together to form walls, means for securing to the foundation of a building for holding a base of each of the panels, means for holding tops of the panels and a roof structure.

16. A rectilinear composite load-bearing building panel for building structural load-bearing walls of permanent buildings, having a pair of opposed faces, a top surface, a pair of opposed sides and a bottom surface, the panel comprising a pair of spaced-apart rigid face boards of thermally non-conductive, fire resistant material, a rigid insulating material sandwiched between, and adhering to the face boards to form a composite structure capable of withstanding compressive forces between the top surface and the bottom surface of at least 5 kN per meter length of the panel, an elongated member extending through the panel and having a pair of opposed flanges, wherein the opposed flanges are secured to the pair of face boards to resist relative movement between the face boards in the plane of the panel and out of the plane of the panel and wherein the opposed sides each have a profiled shape for mating with a correspondingly profiled side of an adjacent panel and wherein the sides have securing means for securing them to sides of adjacent panels.
