Building element of mineral wool and fiber-reinforced plastic
View Patent ↗A new type of building element comprising a core of mineral wool which is enclosed in a covering of fiber-reinforced plastic which is closed on the edges, the mineral wool in the form of layered blocks that are arranged in such a way that the layers are essentially perpendicular to the main side panels of the covering. One or more load-bearing structures which comprise fiber-reinforced plastic can connect the opposite main panels of the covering. The load-bearing structures can also comprise various kinds of core materials. The building elements can have a wear coating and various kinds of surfaces, and be used for the construction of buildings and other structures.
1. A building element, said building element comprising:
a core of mineral wool enclosed in a covering of fiber-reinforced plastic comprising two oppositely arranged parallel main side panels and at least one load bearing structure comprising fiber-reinforced plastic
wherein:
said covering is closed on the edges,
the core comprises layered mineral wool blocks that are arranged in such a way that the layers are essentially perpendicular to the main side panels,
said at least one load bearing structure connects the opposite main side panels of the covering,
the covering of fiber-reinforced plastic further comprises an outer main side panel that forms an enclosed space between said outer main panel and one of the parallel main side panels, and
said outer main side panel is not directly connected to the at least one load bearing structure.
2. The building element according to claim 1 , wherein one or both of the two oppositely arranged parallel main side panels comprises a core material in a covering of fiber-reinforced plastic.
3. The building element according to claim 2 , wherein the core material of said one or both of the two oppositely arranged parallel main side panels comprises polyvinyl chloride foam, polypropylene, polyurethane, polystyrene, polymethyl methacrylate, polyetherimide, styrene-acrylonitrile, balsa wood, plywood, aramid, aluminum, or any combinations of these.
4. The building element according to claim 1 , further comprising a wear coating.
5. The building element according to claim 1 , wherein said covering of fiber-reinforced plastic comprises glass fibers, carbon fibers, basalt fibers or any combination of these.
6. The building element according to claim 1 , wherein the covering of fiber-reinforced plastic comprises polyester, vinyl ester, an epoxy polymer, or any combination of these.
7. The building element of claim 1 , wherein said enclosed space between said outer main panel and one of the parallel main side panels is filled with a core material.
8. The building element of claim 7 , wherein said core material with which said enclosed space between said outer main panel and one of the parallel main side panels is filled is selected from: polyvinyl chloride foam, polypropylene, polyurethane, polystyrene, polymethyl methacrylate, polyetherimide, styrene-acrylonitrile, balsa wood, plywood, aramid, aluminum, and any combination of these.
9. A house comprising a building element according to claim 1 .
10. The house of claim 9 , comprising at least one of an outer wall, a ceiling, and a floor made of building elements according to claim 1 .
11. The building element according to claim 1 , wherein the at least one load bearing structure that connects the opposite main side panels of the covering comprises a core material in a covering of fiber-reinforced plastic.
12. The building element according to claim 11 , wherein the core material of the the at least one load bearing structure comprises polyvinyl chloride foam, polypropylene, polyurethane, polystyrene, polymethyl methacrylate, polyetherimide, styrene-acrylonitrile, balsa wood, plywood, aramid, aluminum, or any combinations of these.
13. The building element according to claim 11 , further comprising a unidirectional reinforcement mat on top of or under the at least one load bearing structure.
