Building panel element and method for manufacturing same

Claim 2

A building panel element comprising: a rigid block of insulating foam having two opposed major surfaces and thickness between said surfaces; a plurality of rectilinear thin strip members embedded in said foam block substantially flush with one of said major surfaces and spaced from the other of said major surfaces, each of said strip members being adapted to receive and hold fastening means and to assist in rigidifying said foam block, said foam filling the spaces between said strip members; said insulating foam contributing substantially to the rigidity of said building panel element.

Claim 3

A building panel element as claimed in claim 1, including a peripheral frame enclosing said foam block substantially from one said major surface to the other, with said plurality of rectilinear thin strip members arranged on one side of said peripheral frame.

Claim 4

A building panel element according to claim 1, further comprising rigidifying means on the other of the said major surfaces of said block of foam.

Claim 5

A building panel element according to claim 3, wherein the rigidifying means comprises a plate element.

Claim 6

A building panel element according to claim 4, wherein the plate element is made of wood.

Claim 7

A building panel element according to claim 1, wherein the thin members are flush with the said major surface.

Claim 8

A building panel element according to claim 1, wherein each thin member is a wooden strip.

Claim 9

A building panel element according to claim 1, wherein the foam is reinforced with glass fibers.

Claim 10

A building panel element according to claim 1, wherein the surface of the block adjacent to the thin members is covered with a protective sheet.

Claim 11

A building panel element according to claim 1, wherein the thin members are parallel.

Claim 12

A building panel element according to claim 1, further comprising means for interconnecting the thin members.

Claim 13

A building panel element comprising a rectangular frame, having a thickness, a plurality of rectilinear thin members arranged on one side of the rectangular frame in predetermined spaced relationship, each of the thin members being adapted to receive and hold fastening means, and a block of insulating foam extending throughout the frame within the thickness thereof and filling the spaces between the thin members.

Claim 14

A building panel element comprising a rectangular frame, having a thickness, a plurality of rectilinear thin members arranged on one side of the rectangular frame in predetermined spaced relationship, each of the thin members being adapted to receive and hold fastening means, and a block of insulating foam extending throughout the frame within the thickness thereof and filling the spaces between the thin members.

Claim 15

A building panel element according to claim 12, further including rigidifying means arranged on the other side of the rectangular frame.

Claim 16

A building panel element according to claim 13, wherein said rigidifying means is a plate element.

Claim 17

A building panel element according to claim 12, wherein the thin members are generally parallel and further comprising at least one intermediate rigidifying element incorporated into the block and extending transverse to the thin members.

Claim 18

A building panel element according to claim 14, wherein the plate element is made of wood.

Claim 19

A building panel element according to claim 12, wherein the block of foam is reinforced by glass fibers.

Claim 20

A building panel element according to claim 12, wherein the said one side of the rectangular frame is covered with a protective sheet,

Claim 21

A building panel element according to claim 12, wherein the thin members extend parallel to the longer side of the rectangular frame.

Claim 22

Method for manufacturing a building panel element comprising the steps of: producing a rectangular frame having a front plane surface and rear plane surface with a thickness between said surfaces, covering the rear surface of the frame with a plate elememt, securing a plurality of rectilinear thin members in a predetermined space relation-ship on the front surface of the frame, covering the front surface of the frame and the thin members with removable flat cover for defining between said cover and the plate element a closed volume, and injecting an insulating foam within the said volume.

Claim 23

Method for manufacturing a building panel element comprising the steps of: producing a rectangular frame having a front plane surface and rear plane surface with a thickness between said surfaces, covering the rear surface of the frame with a plate elememt, securing a plurality of rectilinear thin members in a predetermined space relation-ship on the front surface of the frame, covering the front surface of the frame and the thin members with removable flat cover for defining between said cover and the plate element a closed volume, and injecting an insulating foam within the said volume.

Claim 24

Method according to claim 20 in which an asphalt paper sheet is located between the front surface of the frame and the flat cover before injecting the foam.
