9. The building element of claim 1, wherein said U-sections have means for connecting adjacent building elements with each other.
10. The building element of claim 1, wherein two opposite U-sections are displaced along respective peripheral portions in such manner that each form a protruding portion.
11. The building element of claim 1, wherein said U-sections are made of sheet metal.
12. The building element of claim 1, wherein said insulating means is made of cellular plastic.
13. The building element of claim 1, wherein said insulating means consists of a parallelepiped block made of lightweight material.
14. The building element of claim 1, wherein said insulating means comprises a plurality of blocks made of lightweight material, which are assembled so as to form a unit constituting said insulating means.
15. The building element of claim 1, which has the shape of a rectangular wall element with four U-sections, which are identical in pairs.
16. A building element comprising:
an insulating means having two opposite large faces, a circumference and a peripheral edge portion with an edge surface, and
a frame structure extending along a major part of or the whole circumference of said insulating means and comprising a number of elongate sections that are essentially U-shaped in cross section, each U-section having flanges and a web,
wherein said insulating means is made of lightweight material and is self-supporting,
wherein said U-sections are arranged in such manner on said peripheral edge portion of said insulating means that said flanges of each U-section grasp said edge portion of said insulating means and are located on an outside of said two large faces thereof, while said web of said U-section is caused to abut against said edge surface of said insulating means, and
wherein said U-sections are identical in cross section.
17. A wall construction comprising a number of juxtaposed building elements according to any one of the preceding claims.
18. A method for producing a polygonal building element, wherein a number of U-sections are arranged along a major part of or the whole peripheral portion of a self-supporting insulating means made of lightweight material, a frame structure for the insulating means being formed of the U-sections, said U-sections being arranged in such manner that flanges of each U-section are caused to grasp said edge portion of said insulating means so that said flanges are located on an outside of said large faces thereof, while webs of the U-sections are caused to abut against said edge surface of the insulating means.
19. The method of claim 17, wherein said U-sections are interconnected at their ends.
20. The method of claim 18, wherein said U-sections are interconnected at their ends in a number of connection points.
21. The method of claim 19, wherein said flanges of said U-sections are arranged to overlap in the connection points.
22. A method of making a wall construction, wherein a number of building elements according to any one of claims 1-15 are arranged side by side on a base and interconnected by means of transverse sections, which are connected with said building elements.
23. The method of claim 21, wherein said building elements are connected with each other with the aid of mutually engaging connecting means on the sides of said building element.
24. The method of claim 22, wherein said building elements are arranged in a runner, which is U-shaped in cross section and anchored in a base.
The claims below are in addition to those above.
