• FR2909695 discloses a composite structure for the manufacture of walls, panels, or slabs, comprising a wooden supporting frame coated with a binding product composed of cement or lime mixed with reinforcing particles. in wood.
• a structure does not have sufficient lift, in particular for making constructions with several floors.
• a method comprises several steps and it is particularly long to implement.
• Mention may also be made of floors made from a concrete slab in which reinforcements are integrated. The slab is then placed where you want to make a floor, then pour concrete on the slab to finalize the floor, in particular by embedding the exposed parts of the reinforcements in the concrete. But in the event of a fire, the reinforcements can heat up and cause the concrete to burst, causing the floor to sag.
• An object of the invention is to overcome these drawbacks, and more particularly to provide means for producing floors or walls more quickly.
• Another object is to provide means for producing a plate intended to produce a floor or a wall, which can be prefabricated and transportable from the place of prefabrication to the place of assembly where the floor and the wall are made.
• Another object is to provide means for producing floors which are resistant to fire.
• a plate intended to produce a floor or a wall, comprising several beams, each beam comprising an armature fixed to a base, each base being produced from a hardening fixing material, the plate comprising a support having several formwork parts projecting from a support receiving surface, the formwork parts forming housings to receive the beams respectively and whose bottom is formed by the receiving surface of the support, each beam being located in a respective housing where the base of the beam is fixed to the bottom of the housing.
• the support is a single piece.
• a plate which allows a floor or a wall to be produced more quickly, since it incorporates both a support and beams held together, which avoids having to install several elements during the mounting of the floor or the wall.
• the plate can be prefabricated before making the floor or the wall from such a plate. The prefabrication of the plate can be carried out outside the mounting location, with greater control of manufacturing.
• the support can be made from a curable support material in which wooden elements are embedded.
• Such a plate offers effective fire resistance because it protects the beams and prevents their expansion in the event of a fire.
• the support is made from, or comprises, a material comprising an organic element of plant origin.
• Each beam can be configured so that its frame is isolated from the support so that its frame is not in direct contact with the support.
• a slab is proposed for producing a floor, comprising a plate as defined above, and a concrete covering covering the formwork parts and the housing of the plate.
• the curable material for fixing each beam may be concrete, the proportions of which are identical to that of the concrete covering the shuttering parts and the housings.

• a method of manufacturing a slab as defined above comprising:
• FIG. 1 schematically illustrates a sectional view of an embodiment of a support for beams according to the invention
• - Figure 2 schematically illustrates a sectional view of an embodiment of a plate
• FIG. 3 schematically illustrates a sectional view of an embodiment of a slab.
• FIG 1 there is shown an embodiment of a support 6, in Figure 2, there is shown an embodiment of a plate 1, and in Figure 3, there is shown an embodiment of 'a slab 2.
• Slab 2 is used, in particular, for covering floors, for example a floor, or walls.
• the plate 1 is intended to make a floor or a wall. That is to say that the plate 1 can be placed horizontally to make a floor, or vertically to make a wall.
• the frame 4 has a parallelepiped shape or can have a triangular section.
• the beam 3 extends along a longitudinal axis A of the support 6.
• the length of a beam 3 is greater than its height and its width.
• the support 6 is intended, in particular to support the beams 3.
• the support 6 comprises several formwork parts 7 projecting from a receiving surface 8 of the support 6. More generally, the formwork parts 7 form housings 9 shaped for receive respectively the beams 3 to support.
• a housing 9 has a bottom corresponding to the receiving surface 8 of the support 6, and side walls 10, 11 corresponding to the side walls of two formwork parts 7 located consecutively on the support 6.
• each beam 3 is located in a housing 9.
• the base 5 of a beam 3 is fixed to the bottom of the housing, that is to say on the receiving surface 8 of the support 6.
• the support 6 is a single piece, that is to say - say that the support is made from a single piece.
• an easily transportable plate is provided because the beams 3 are held by mechanical fixing to the support 6.
• the construction of the floors is better controlled since it is no longer necessary to assemble the beams 3 at the place of production of the floor. .
• a support 6 is provided, a contact surface 13 of which, opposite the receiving surface 8, is continuous.
• the support 6 has no cracks and therefore no brittleness zones.
• the plate 1 therefore has better resistance to bending and offers a fire-fighting property since the support 6 partially protects the beams 3.
• the support 6 is made from a curable support material in which are embedded wooden elements.
• the wooden elements can be of different sizes.
• the curable support material can be a binder, such as a cement, and in this case the support is made of concrete-wood.
• the concrete-wood material provides an improved fire-fighting property on the floor. Wood is a better thermal insulator than sand used in conventional concrete.
• the binder coats the wooden elements and protects them from the flames.
• the support 6 can be produced at starting from, or understanding, a material comprising an organic element of plant origin.
• An organic element of plant origin can be wood, straw, cellulose, hemp or cork.
• An organic element includes carbon.
• a support 6, produced from, or comprising, a material comprising an organic element of vegetable origin makes it possible to produce floors from carbon of natural origin, that is to say an organic element which was not produced by the chemical industry, and which did not require additional energy expenditure.
• each beam 3 is configured so that its frame 4 is isolated from the support 6 so that its frame 4 is not in direct contact with the support 6.
• the base 5 is fixed directly to the support
• the armature 4 is fixed directly to the base, and the armature 4 is not in direct contact with the support 6. That is to say that each armature 4 has an exposed part to the air free located outside the base 5.
• the plate 1 is therefore lightened since the beams 3 are not fully coated.
• the fire-fighting property of the floor is improved, because when flames are in contact with the contact surface 13, opposite the receiving surface 8, of the support, the flames are not in direct contact with the beams 3
• Such a support 6 thus limits the propagation of heat in the event of a fire.
• the support 6 made from a concrete-wood material protects the beams from excessive expansion which could occur in the event of a fire.
• the base 5 is preferably made of concrete, so as to securely fix the base 5 to the support 6.
• the concrete forming the base 5, when cast, easily penetrates into the microcavities of support 6.
