Panels designed for producing a wall and methods for producing such panels
Panel designed for making a wall, including a monobloc part made from concrete inside which pieces of wood are sunk, at least one through aperture being formed inside the monobloc part, the panel including at least one reinforcement element providing a bending resistance and housed inside said at least one through aperture, said at least one reinforcement element being formed by an armature coated with a hardening product including a binder.
1 . A panel designed for fabrication of a wall, comprising:
at least one monobloc part made from wood chips covered by concrete, the wood chips having a length between 20 mm and 60 mm and a thickness between 1 mm and 5 mm, the at least one monobloc part having a weight ratio of wood chips between 30% and 70% of a total weight of the at least one monobloc part, the at least one monobloc part having microcavities at a surface and the microcavities representing between 30% and 50% of the surface, the at least one monobloc part defining at least one through aperture designed to form a housing, the at least one monobloc part forming a ring around the housing;
at least one reinforcement element housed in the housing, the at least one reinforcement element comprising an armature comprising one or more rods or bars, the armature being coated with a hardening product comprising an additional concrete, the hardening product being present in the microcavities.
2 . The panel according to claim 1 , wherein the hardening product is chemically different from the concrete of the at least one monobloc part, the hardening product having a Young's modulus at least 10% higher than the Young's modulus of the concrete of the at least one monobloc part.
3 . The panel according to claim 2 , wherein the hardening product comprises a volume content of wood chips that is at least 10% lower than a volume content of wood chips of the at least one monobloc part.
4 . The panel according to claim 3 , wherein the hardening product is devoid of wood chips.
5 . The panel according to claim 1 , wherein the hardening product comprises wood chips having an average size at least 30% smaller than an average size of the wood chips of the at least one monobloc part.
6 . The panel according to claim 1 , wherein several reinforcement elements are housed in said at least one housing and wherein the hardening product comprising a binder arranged between the reinforcement elements, the binder being a concrete devoid of wood chips.
7 . The panel according to claim 1 comprising first and second monobloc parts of the at least one monobloc part each made from concrete and wood chips, the first and second monobloc parts being separated from one another by the housing, said at least one reinforcement element being fixed to said first and second monobloc parts.
8 . The panel according to claim 7 , wherein the first monobloc part is provided with a first shoulder and the second monobloc part is provided with a second shoulder complementary to the first shoulder so that the first and second shoulders form the housing.
9 . The panel according to claim 8 , wherein the first monobloc part is perpendicular to the second monobloc part.
10 . The panel according to claim 7 , wherein the housing is formed in at least one monobloc part, said at least one reinforcement element is fixed to a first surface of said at least one monobloc part and an additional reinforcement element is fixed on a second surface of said at least one monobloc part opposite the first surface.
11 . A method for manufacturing a panel according to claim 7 , wherein it comprises provision of at least two monobloc parts each made from concrete in which pieces of wood are sunk and separated from one another by at least one housing, placing an armature in said at least one housing, and pouring of a hardening product comprising a binder into said at least one housing to coat the armature and fix the latter to said at least two monobloc parts.
