DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

La présente invention concerne le domaine du bâtiment, plus particulièrement de la construction de maisons ou d'immeubles à partir de blocs de construction. Plus particulièrement, l'invention se rapporte à la construction d'un mur ou analogue à partir de blocs de construction superposables. L'invention concerne la construction de type mur ou analogue, s'étendant au moins sur une direction horizontale et une direction verticale. Cette construction comporte une pluralité de rangées de blocs de construction superposées, et a un bloc de construction de forme sensiblement parallélépipédique. Chaque bloc de construction comprenant une face supérieure au moins apte à être associée avec la ou les faces inférieures d'un ou de deux autres blocs de construction analogues, une face inférieure au moins apte à être associée avec la ou les faces supérieures d'un ou de deux autres blocs de construction analogues.The present invention relates to the field of building, more particularly the construction of houses or buildings from building blocks. More particularly, the invention relates to the construction of a wall or the like from stackable building blocks. The invention relates to wall-type construction or the like, extending at least in one horizontal direction and one vertical direction. This construction comprises a plurality of rows of superimposed building blocks, and has a building block of substantially parallelepiped shape. Each building block comprising an upper face at least capable of being associated with the lower face(s) of one or two other similar building blocks, a lower face at least capable of being associated with the upper face(s) of a or two other similar building blocks.

ETAT DE LA TECHNIQUESTATE OF THE ART

Les parpaings en béton ou en mortier sont très couramment utilisés pour la réalisation d'ouvrages de construction.Concrete or mortar blocks are very commonly used for the construction of construction works.

Par exemple, les publications suivantes montrent des exemples de parpaings : EP0726369 , US5775047 , FR3032735 et DE4402135 .For example, the following posts show examples of concrete blocks: EP0726369 , US5775047 , FR3032735 And DE4402135 .

De nombreuses problématiques se posent alors vis-à-vis de ces parpaings, qui doivent à la fois être facilement manipulables pour la construction, et présenter des caractéristiques intéressantes notamment en termes d'isolation thermique et phonique.Many problems then arise with regard to these concrete blocks, which must both be easily handled for construction, and present interesting characteristics, particularly in terms of thermal and sound insulation.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

La présente invention vise à remédier à ces inconvénients.The present invention aims to remedy these drawbacks.

A cet effet, la présente invention vise un bloc de construction de forme sensiblement parallélépipédique et comprend une face supérieure au moins apte à être associée avec la ou les faces inférieures d'un ou de deux autres blocs de construction analogues, une face inférieure au moins apte à être associée avec la ou les faces supérieures d'un ou de deux bloc de construction analogues, au moins deux ouvertures verticales, le bloc de construction comprend une face avant, une face arrière et deux faces latérales avec un renfoncement faisant apparaître deux bourrelets sur les côtés des deux faces latérales, ledit bloc de construction est remarquable en ce que

  • ledit bloc de construction (20) est constitué de mousse expansive et de sable, ladite mousse expansive étant une mousse polyuréthane, la quantité de mousse expansive est comprise entre 0,5% à 15% du poids en sable, de préférence entre 2% à 8%, de préférence entre 3% et 6%,
  • entre la face arrière (23) et la face avant (24) se trouve une partie en isolation (29) s'étendant dans la largeur du bloc de construction (20), ladite partie en isolation (29) étant de forme sensiblement parallélépipédique et dont la hauteur et la longueur est identique au bloc de construction (20).
For this purpose, the present invention aims at a building block of substantially parallelepiped shape and comprises an upper face at least capable of being associated with the lower face(s) of one or two other similar building blocks, a lower face at least capable of being associated with the upper face(s) of one or two similar building blocks, at least two vertical openings, the building block comprises a front face, a rear face and two side faces with a recess revealing two beads on the sides of the two lateral faces, said building block is remarkable in that
  • said building block (20) is made up of expanding foam and sand, said expanding foam being a polyurethane foam, the quantity of expanding foam is between 0.5% to 15% of the weight of sand, preferably between 2% to 8%, preferably between 3% and 6%,
  • between the rear face (23) and the front face (24) there is an insulating part (29) extending across the width of the building block (20), said insulating part (29) being of substantially parallelepiped shape and whose height and length is identical to the building block (20).

Grâce à ces dispositions, le bloc de construction permet d'isoler et d'insonoriser. Il est également plus léger, plus facile à transporter et à manipuler.Thanks to these provisions, the building block makes it possible to insulate and soundproof. It is also lighter, easier to transport and handle.

On entend par mousse expansive, une mousse polyuréthane « monocomposant » qui gonfle en séchant.By expanding foam we mean a “single-component” polyurethane foam which expands as it dries.

Le polyuréthane liquide se transforme en mousse par une réaction chimique (appelée polymérisation) grâce à l'humidité de l'air ou à un apport en eau. Il est généralement conditionné en bombe aérosol à secouer avant usage. Elle peut s'utiliser à l'intérieur et à l'extérieur, adhère extrêmement bien à la plupart des matériaux (béton, brique, plastique, plâtre, métaux, etc.), a des qualités isolantes exceptionnelles (1 centimètre de mousse équivaudrait à 40 mètres de béton) et gonfle énormément (une bombe de 500 millilitres donne approximativement 20 litres de mousse).Liquid polyurethane transforms into foam through a chemical reaction (called polymerization) using humidity in the air or an addition of water. It is generally packaged in an aerosol can to be shaken before use. It can be used indoors and outdoors, adheres extremely well to most materials (concrete, brick, plastic, plaster, metals, etc.), has exceptional insulating qualities (1 centimeter of foam would be equivalent to 40 meters of concrete) and swells enormously (a 500 milliliter bomb gives approximately 20 liters of foam).

L'invention est avantageusement mise en oeuvre selon les modes de réalisation et les variantes exposées ci-après, lesquelles sont à considérer individuellement ou selon toute combinaison techniquement opérante.The invention is advantageously implemented according to the embodiments and the variants set out below, which are to be considered individually or according to any technically effective combination.

Le bloc de construction 20 comprend deux faces latérales avec un renfoncement 21 et une face avant 24 et une face arrière 23.There figure 1 represents a building block 20 of substantially parallelepiped shape and comprises an upper face 25 at least capable of being associated with the lower face(s) of one or two other similar building blocks (not shown), a lower face (not shown ) at least capable of being associated with the upper face(s) of one or two similar building blocks 20 (not shown), at least two vertical openings 22. The building block 20 comprises two lateral faces with a recess 21 and a front face 24 and a rear face 23.

Le bloc de construction 20 comprend une quantité de mousse expansive qui est de 4,6% le poids sable. Selon un exemple, la quantité de mousse expansive est de 70 ml et la quantité de sable est de 1,5kg.Building block 20 includes a quantity of expanding foam which is 4.6% by weight sand. According to an example, the quantity of expanding foam is 70 ml and the quantity of sand is 1.5 kg.

Le pourcentage entre 3 et 6% du poids en sable correspond au bon compromis entre la quantité de mousse expansive et la bonne tenue mécanique du bloc de construction 20.The percentage between 3 and 6% of the weight of sand corresponds to the good compromise between the quantity of expanding foam and the good mechanical strength of the building block 20.

La figure 2 représente une vue du dessus d'un autre exemple d'un bloc de construction 20. Cette figure reprend certains éléments de la figure précédente.There figure 2 represents a top view of another example of a building block 20. This figure repeats certain elements of the previous figure.

La face avant 24 comporte un parement 26 rectangulaire, de section normalement rectangulaire.The front face 24 comprises a rectangular facing 26, of normally rectangular section.

The joint extends all around the facing 26 on the horizontal edge of the front face 24 and the vertical edge.

Le bloc de construction 20 comporte deux ouvertures verticales 22. Les deux ouvertures verticales 22 sont rectangulaires et disposées symétriquement de part et d'autre du plan médian transversal du bloc de construction 20.The building block 20 has two vertical openings 22. The two vertical openings 22 are rectangular and arranged symmetrically on either side of the transverse median plane of the building block 20.

Sur les deux faces latérales, chaque renforcement 21 fait apparaître un bourrelet 28 vertical en relief destiné respectivement à venir en appui contre les bourrelets 28 verticaux des blocs de construction 20 adjacents.On the two lateral faces, each reinforcement 21 reveals a vertical bead 28 in relief intended respectively to come to bear against the vertical bead 28 of the adjacent building blocks 20.

La figure 3 représente une vue en perspective d'un autre exemple d'un bloc de construction 20. Cette figure reprend certains éléments de la figure précédente.There Figure 3 represents a perspective view of another example of a building block 20.

La face avant 24 comporte deux parements 26 rectangulaires, de section normalement rectangulaire. Entre les deux parements 26 rectangulaires se trouve un joint creux 27. Autrement dit, chaque parement 26 est bordé sur une de ses arêtes verticales par un joint creux 27.The front face 24 comprises two rectangular facings 26, of normally rectangular section. Between the two rectangular facings 26 there is a hollow joint 27. In other words, each facing 26 is bordered on one of its vertical edges by a hollow joint 27.

On entend par joint creux 27, un rainurage ou une gorge dans la matière.Hollow joint 27 means a groove or groove in the material.

Lors de l'empilement des blocs de construction 20, chaque parement 26 est toujours séparé d'un des parements 26 adjacents par un joint 27 : soit constitué entre deux parements 26 d'un même bloc de construction 20, soit constitué par un parement 26 d'un bloc et d'un autre parement 26 adjacent d'un autre bloc de construction 20 adjacent.When stacking the building blocks 20, each facing 26 is always separated from one of the adjacent facings 26 by a joint 27: either constituted between two facings 26 of the same building block 20, or constituted by a facing 26 of a block and another adjacent facing 26 of another adjacent building block 20.

Les joints jouent le rôle des joints en creux réalisés, dans le montage traditionnel avec du mortier.The joints play the role of hollow joints made, in traditional assembly with mortar.
