Abstract

A building element for a building includes a framework with at least one wooden beam and at least one facing sheet fixed to the beam of the framework. The building element also includes an insulating component made of mineral wool affixed to the beam in such a way as to cover the beam on the one hand on a frontal face and on the other hand on at least a part of the lateral faces. The insulating component affixed to the frontal face is interposed between the facing sheet and the beam.

First claim

1 . A building element for a building comprising:
a framework with at least one wooden beam and at least one facing sheet fixed to the beam of the framework; and an insulating component made of mineral wool affixed to the beam in such a way as to cover said beam on a frontal face and on at least a part of lateral faces, the insulating component affixed to the frontal face being interposed between the facing sheet and the beam.

2 . The building element as claimed in claim 1 , wherein the insulating component made of mineral wool covers the lateral faces completely.

3 . The building element as claimed in claim 1 , wherein the insulating component made of mineral wool is also affixed to a rear face of the beam that is the opposite face to the frontal face, so that the insulating component completely surrounds said beam.

4 . The building element as claimed in claim 3 , wherein, on each face to which the insulating component is affixed, an orientation of fibers of the insulating component comprises a component parallel to the face

5 . The building element as claimed in claim 1 , wherein a thickness of the insulating component is greater than or equal to 15 mm.

6 . The building element as claimed in claim 1 , wherein a density of the insulating component made of mineral wool is greater than or equal to 30 kg/m 3 .

7 . The building element as claimed in claim 1 , wherein the mineral wool of the insulating component is made with high-temperature-resistance mineral wool fibers.

8 . The building element as claimed in claim 1 , wherein the insulating component is affixed to the wooden beam by bonding and/or mechanical fastening.

9 . The building element as claimed in claim 8 , further comprising:
a reinforcing device having at least one part of U-shaped overall cross section, a bottom of the U being positioned facing the frontal face and lateral legs of the U facing the lateral faces, each lateral leg being fixed at an end zone in the lateral face of the beam, the insulating component being interposed either between the reinforcing device and the beam or between the bottom of the U and the facing sheet.

10 . The building element as claimed in claim 9 , wherein a length of each lateral leg of the reinforcing device is greater than half a thickness of the beam.

11 . The building element as claimed in claim 9 , wherein the reinforcing device comprises degassing openings.

12 . A reinforcing device for the building element as claimed in claim 1 , comprising:
a frontal face to be fixed facing a frontal face of a beam; at least two lateral legs to be fixed to the lateral sides of the wooden beam.

13 . The reinforcing device as claimed in claim 12 , wherein a length of each lateral leg of the reinforcing device is greater than 40 mm.

14 . The reinforcing device as claimed in claim 12 , wherein the reinforcing device comprises degassing openings.

15 . An assembly of reinforcing devices, comprising:
at least one pair of the reinforcing device as claimed in claim 12 , the respective lateral legs of which have complementary cutout shapes.

16 . A protection kit for creating the building element as claimed in claim 1 , comprising:
at least one mineral wool panel; and means of reinforcing the panel on the frontal and lateral faces of a wooden beam.

17 . The protection kit as claimed in claim 16 , further comprising:
a panel formed of three continuous or contiguous segments connected by their external faces, the panel being configured to be folded along pliable hinges so that the panel surrounds the wooden beam.

18 . The building element as claimed in claim 1 , wherein a thickness of the insulating component is between 15 mm and 50 mm.

19 . The building element as claimed in claim 1 , wherein a density of the insulating component made of mineral wool is between 80 kg/m 3 and 100 kg/m 3 .

20 . The building element as claimed in claim 3 , wherein, on each face to which the insulating component is affixed, a dominant direction of an orientation of the mineral fibers of the insulating component made of mineral wool is parallel to the face.
