Definitions

the thickness of the panels is conditioned by the thickness of the bales of straw.
This standard thickness is due to existing presses to make these bales.
this thickness must be minimal to allow easy handling and to maintain their parallelepiped shape.
a feature of the invention lies in the implementation of rigid walls including plant aggregates and thus having mechanical and, in particular, thermal properties. Indeed, thanks to the plant aggregates, air is trapped in the rigid walls, which allows to lower their thermal conductivity, and thus to improve the thermal resistance of the building element. In addition, these rigid walls are made at an advantageous cost with binders and inexpensive aggregates.
construction element according to the invention further comprises spacers to keep said two walls at a distance from each other. This also makes it possible to stiffen the construction element.
FIGs 1 and 2 illustrate a modular building element 10 according to a first embodiment of the invention, the first having its front wall 12, the second, its front walls 12 and rear 14.
the first having its front wall 12, the second, its front walls 12 and rear 14.
peripheral walls an upper wall 16 opposite a lower wall 18 and a first lateral 20.
the plant aggregates of the aforementioned type are firstly milled inside a knife mill, for example. This grinding makes it possible to give them a particle size having a size whose distribution is comprised, for example, between 2 mm and 10 mm.
these plant aggregates are mixed with a binder in mass proportions included, for example, between one for one and one for two.
a binder in mass proportions included, for example, between one for one and one for two.
suitable binders are given below.
the mixture is then kneaded to be homogenized. Under certain circumstances, the mixture is heated, for example at temperatures between 70 ° and 90 ° C, so as to promote chemical reactions where appropriate. In addition, heating reduces the viscosity of the mixture and therefore accelerates homogenization. This heating is for example carried out by means of microwaves.
the front 12 and rear 14 walls have the aforesaid dimensions of 1.20 m by 2.50 m and a thickness of 7.5 cm each and are kept spaced from each other by a distance D of 25 mm. cm through the side walls 20, 22, lower 18 and upper 16.
the walls 12, 14, 16, 18, 20, 22 are held together by gluing and / or by metal fasteners.
the insulating material of plant origin intended to be housed inside the cavity is relatively homogeneous and bonded so that it can be maintained between the two rigid walls without the need for a side wall. restraint.
