DESCRIPTION

MODULAR STRUCTURE OF STRAW WALLS FOR BUILDINGS

OBJECT OF THE INVENTION

The present invention refers to a new type of construction, both for its shape and for the materials used, based on the union and coupling of modules in straw segments.

It comes to propose a new concept in the manufacture and construction of homes and buildings, of a sustainable and ecological nature, which is both easy and fast to execute, while reducing the costs to achieve it.

For this, the object of the present invention is to build a house or building in the shape of a hemisphere or dome, using only straw bales as material, and reinforced by adobe, where both its interior and its dimensions (radii of the base of the cap spherical) can be very varied.

Straw bales have been used in traditional construction but never for spherical-shaped houses, and with prefabricated modules such as those proposed by the requested invention, so that the traditional rectangular straw bales would be replaced by structural modules in the form of sections of precast spherical hull.

The industrial application of this invention is within the construction systems, elements and methods, and more specifically, the construction of houses from modular structures of straw segments.

BACKGROUND OF THE INVENTION

Although no invention identical to the one described has been found, we present below the documents found that reflect the state of the art related to it.

Thus, document WO2019048725 refers to a construction material that comprises: - at least between 0.1-6.9% by weight of vegetable straw, - 0.1-25% by weight of carboxymethylcellulose (CMC), methylcellulose (MC ) or a combination of both, - 0.1-12% by weight of natural polysaccharide selected from the group consisting of D-galactose, L-arabinose, L-rhamnose, D-glucuronic acid, natural gums and combinations thereof, preferably gum arabic or gum tragacanth, - water, at least between 0.1 and 45% by weight, where all percentages are percentages by weight with respect to weight total construction material, and its use in molding, extrusion or 3D printing, particularly preferably for the manufacture of furniture or Fallas monuments.

ES2356877 proposes a construction material, a procedure for obtaining said material, a constructive element made using said material and the use of the material as a CO2 sink to immobilize carbon in the long term. Used both in civil construction and in building, it includes the production of construction materials, preferably bituminous mixtures and hydraulic cement or plaster mortars, based on vegetable aggregates such as sawdust, shavings and/or wood fibers, as well as straw, by means of of a method that includes a thermal treatment of heating of the aggregates. The aggregates can be obtained from wood from industrial waste from logging or agricultural companies, as well as from renewable forest plantations.

ES0250060 describes a system for the construction of light and isothermal buildings, essentially characterized in that the walls or walls of the buildings are built by coupling a series of frames that constitute previously prepared construction elements, formed by one or several thicknesses of reeds. , reeds, straw, sticks or similar material, as well as a mixture of these materials, arranged in parallel and with a suitable orientation, which are kept together and fixed to each other on crossbars or strips of wood, metal or suitable material, by means of staples, sewing or other binding elements.

DOP2003000695 claims some blocks that we have in mind is radically different from other traditional blocks. While the traditional blocks are piled up without any security; ours are placed in an orderly manner with mutual intertwining, an arrangement that is determined by their shape. These characteristics, the obligatory interlocking of a block with other Three blocks by four of its six counted, makes a wall built with these like a reinforced concrete wall. Having seen all of the aforementioned, we can say that the time has come for any humble family to have every possibility of building their house with a small amount of resources, since the whole family will be able to participate in the construction process, thus obtaining great savings in money, by raising the building with more or less half the money that is normally used. It does not use a mix joint for construction.

ES2083312 refers to a procedure for manufacturing vaults for construction. Various homogenized materials are involved in the process, such as paper or cellulosic fibers, composed of barley flour, wheat and rice husks, esparto grass, plastics and resins, obtaining a triple action of protection of cellulosic fibers from the attack of alkaline or acid components. ; a degree of incombustibility to organic compounds; and an optimal mechanical resistance of the piece. the addition of cement, lime, plaster and plaster provides consistency and impermeability to the pieces and facilitates subsequent plastering. From this homogenized material, the pieces are obtained, either by molding or through an "extruder", continuously, and subsequent cutting. apart from one Greater resistance, lightness, ease of placement and other advantages help to solve the ecological problem, since they largely use recycled materials.

ES2372073 describes a flexible modular construction system, in which modules are used, each of which comprises three parallel functional zones, one of which is a corridor zone, another a service zone and the third a private space zone. , forming consecutive dwellings with said modules, so that the service area determines a hollow space, in which elements of the service facilities are repeatedly arranged, in correspondence with each module, which are established in connection with the respective general connections. supply of construction services.

ES2707740 claims a device for depositing pasty material intended for the layer-by-layer manufacturing of a large-dimensional three-dimensional structure comprising: -at least three first supports at a distance from the ground, not aligned, respectively supporting three first tensioning devices cables, and - at least a second support kept at a distance from the ground, and supporting a second tensioning device, and - a material supply conduit, kept suspended above the ground, capable of moving at least above of the area between said first three supports, and - a deposition head at the end of said supply conduit suspended, preferably by means of a suspension cable, from said second tensioning device, and - three so-called positioning cables of respective lengths attached to said deposition head at the level of a guide support, at one end and respectively in the first three tensioning devices at its other end, said three positioning cables being able to be tensioned with a differentiated adjustable length by differentiated actuation of the first three tensioning devices and of said second tensioning device, and able to define due to their adjustable lengths, an inverted pyramid with a triangular upper base, the lower tip of said inverted pyramid defining a deposition point in space located substantially at the level of the deposition head at the lower end of the supply conduit, said deposition point being capable of moving in the three XYZ dimensions in the space between the first three supports, by differentiated activation of at least one of said first three tensioning devices.

ES2221494 proposes an ecological block or piece for construction consisting of the combination of chopped or crushed hemp mixed with vegetable fibers and bound in a mortar or mass composed of binders, mineral powders and water-soluble binders that, when mixed in a mixer, give a mortar. of high density to be molded in formats and sizes of pieces for the construction that set in raw.

Conclusions: As can be seen from the research carried out, none of the documents found solve the problems posed as does the proposed invention.

DESCRIPTION OF THE INVENTION

The modular structure of straw segments for buildings, object of the present invention, is constituted from a bale of pressed and prefabricated straw, which comprises a section shape of a spherical hull, although they can also be wedge-shaped modules, complementary to others. with traditional rectangular shapes, to gradually adapt a continuity of curved shape.

The basic segment will determine the diameter and size of the dwelling/building in question, as well as the number of modules necessary to close the spherical hull shape. These segments can have straight sides, or have protrusions and recesses on opposite sides, so that they help to better fit and couple some modules to others.

The basic segment modules are fixed to each other by means of interior rods that are inserted into both adjacent modules, and to hold the bales placed at a higher level, straps can be used to support them while the structure is closed. or lateral supports in the form of cord ribs from side to side, chicken coop cloth, etc.
