Definitions

  • the present invention relates to the field of elaborate materials intended for the construction of the building.
  • the invention relates to a masonry block intended in particular for the construction of an individual dwelling or of a small building.
  • the masonry block must have the following characteristics: low weight to be portable, high crush resistance, low thermal conductivity, mechanical and chemical compatibility with the other materials used for the construction of buildings and in particular plasters and plasters, a satisfactory surface appearance after treatment on site, good fire resistance and a cost price per square meter of finished wall, with chains, lintels and frames, as low as possible.
  • the masonry block placed at the foot of the wall must withstand the permanent loads of the building and the service loads carried by the floors. It is recognized that the block must withstand, without crushing, a compression ratio of 3 MPa when it is used in the construction of a building having a ground floor topped by three floors.
  • Wood has a low conductivity and a high resistance to compression, but it has the major disadvantage of being of high cost.
  • the object of the present invention is to propose an elementary block of masonry which overcomes the aforementioned drawbacks, which is both portable, insulating and load-bearing, which is chemically compatible with the other materials used in the building such as plaster and coatings, which has a satisfactory surface appearance after treatment on site, good fire resistance and which is of a low cost price.
  • the proposed masonry block intended more especially for the construction of a dwelling or a building, is characterized in that it comprises: an external water and gas tight envelope delimiting an internal cavity having substantially the shape of a straight parallelepiped, and a dose of a granular and dry material filling the whole of said cavity, and in that the interstitial voids existing between the grains of the granular material contain a gas or a mixture of dry gases in depression with respect to the outside.
  • the proposed block retains its initial parallelepiped shape.
  • the vacuum existing inside the sealed envelope increases the friction and the cohesion of the grains of the material filling the internal cavity of the envelope. Thanks to the friction existing between the grains of the aggregate, the assembly of granular material and vacuum envelope is then able to withstand mechanical loading.
  • the block also comprises continuous or sufficiently long fibers to be assimilated to continuous fibers, resistant to traction and arranged in the dose of granular material.
  • the continuous or long fibers are arranged in horizontal layers.
  • the horizontal plies are formed by the folds of a geotextile band resistant to traction and little deformable, arranged in superposed folds in said cavity, and the dose of granular material comprises several superposed layers separated by the folds of the strip of geotextile.
  • the block may also include, in addition to the geotextile strip, continuous or long fibers arranged randomly in the superposed layers of the dose of granular material.
  • the granular material is advantageously constituted by light aggregates.
  • the selected aggregates have a useful conductivity less than or equal to 0.10 W / m. o C and a compressive strength greater than or equal to 3 MPa.
  • the aggregates being dry and the air or other gas filling the interstitial voids existing between the aggregates also being dry, the block has a low useful conductivity, and this conductivity is preserved over time as a result of the tightness of the envelope.
  • the aggregate is roughened by crushing which has, in addition, the advantage of reducing the average size of the interstitial voids of the aggregate, which reduces the convection of air or other gas in this material with macro-porosity.
  • the aggregates chosen are shales or expanded clays, the basic materials being very common in nature and at a low cost price.
  • the geotextile strip used is preferably made of fiberglass. Fiberglass is indeed tensile, without excessive deformation and behaves very well in the event of fire, while having a low thermal conductivity.
  • the proportion of the equivalent thickness of the geotextile strip compared to the thickness of a layer of aggregates is of the order of 0.2%.
  • This volume proportion of geotextile strip in relation to the aggregate volume allows the proposed masonry block to withstand a compression ratio of 3 MPa without excessive deformation and without appreciably altering the thermal conductivity of the block.
  • the envelope In order to keep the masonry block its low thermal conductivity, the envelope must be waterproof against water vapor and sufficiently airtight or other gas tight.
  • the envelope is preferably produced from a heat-sealable composite strip comprising an aluminum film placed between a polyester film and a polyethylene film and firmly adhering to the latter. These three materials forming a single composite strip allow the envelope to resist tearing, to be waterproof and heat sealable.
  • the polyester film placed outside the envelope allows the block to receive joint adhesives and coatings without special treatment.
  • the dry air of the internal cavity can be replaced by carbon dioxide.
  • the present invention also provides a method of manufacturing the masonry block described above.
  • a sealed rectangular bag provided with a cover sheet intended to form the upper opening of the bag, from a complex band which is waterproof against water vapor and gases
  • the rectangular bag is placed in a suitable mold so as to cover the five internal faces of the mold, one end of a band of geotextile having a width slightly less than that of the bag applied against the internal faces of the mold in the bottom of the bag
  • a first layer of aggregates is poured into the bag placed in the mold while the mold is subjected to vibrations
  • a first fold of the geotextile strip over the first layer of aggregates
  • a new layer of aggregates is deposited on the geotextile fold while vibrating the mold
  • we fold another fold of the geotextile strip in the direction opposite to the drawdown of the first ply, and we continue to deposit other layers of aggregates with the interposition of a ply of geotextile strip between two neighboring layers until the last layer of aggregates
  • the masonry block 1 comprises a sealed external envelope 2 having the shape of a rectangular parallelepiped delimiting a cavity 3 in which are arranged layers 4a, 4b, 4c of light mineral aggregates 5.
  • the layers superimposed 4a, 4b, 4c are separated from each other and from the lower and upper walls of the envelope 2 by a geotextile strip 6 resistant to traction and non-deformable.
  • the geotextile strip 6 has portions of horizontal strips 6a, 6b, 6c, 6d parallel to the upper 7a and lower faces 7b of the masonry block 1 and portions of vertical strips 8a, 8b and 8c, arranged alternately against the internal walls 9a front 10a and rear 10b faces of the casing 2, and respectively connecting the strip portions 6a and 6b, 6b and 6c, 6c and 6d.
  • the interstitial voids 11 existing between the aggregates 5 of the layers 4a, 4b and 4c are filled with air or another dry gas in depression relative to the pressure prevailing outside the envelope 2.
  • the dimensions of the masonry block 1 are chosen overall so that its weight is not excessive and that the block remains manipulated by the mason.
  • the height of the block 1 can be close to 20 cm and its width and thickness close to 30 cm.
  • the weight of block 1 is then close to 10 kg depending on the density of the aggregates 5.
  • envelope 2 and the geotextile strip 6 are chosen on the one hand, in such a way that the masonry block 1 withstands a compression rate of 3 MPa which is significantly higher than the rates of the real stresses to which it will be subjected, and, on the other hand, that the wall produced with such blocks has a thermal conductivity less than or equal to 0.12 W / m. o C.
  • the preceding table seems to indicate that there is a fairly general correlation between the bulk density of light and dry aggregate, its compressive strength and its thermal conductivity.
  • the light aggregate 5 will be chosen from the range of shales or clays with a density slightly less than 400 kg / m3, which corresponds to a thermal conductivity less than or equal to 0.10 W / m. o C and a compressive strength greater than or equal to 3 MPa. This compressive strength corresponds to the crushing of loose aggregates.
  • the envelope 2 is produced from a composite strip 12 comprising an aluminum film 13 placed between a polyester film 14 and a polyethylene film 15.
  • the polyester film located at the exterior of the block provides the tear resistance function
  • the aluminum film provides the sealing function
  • the polyethylene film allows the edges of the envelope to be welded during the manufacture of the masonry block 1 .
  • the envelope 2 is waterproof against water vapor, since it is well known that the conductivity of a material increases with its water content.
  • the geotextile strip 6 is made of the stiffest material possible, so as to avoid the deformability of the masonry block 1, chemically compatible with light aggregates, fire resistant, and of low conductivity, because its horizontal arrangement makes it a vector of heat transport between the internal faces 10a and external 10b of the wall.
  • Kevlar and carbon fiber cannot be used for the moment because of their cost, and between steel and glass, we prefer the one with the lowest thermal conductivity, namely glass.
  • the geotextile layers 6a, 6b, 6c, 6d must withstand the horizontal stresses due to the weight of the structure; it has been calculated that with a geotextile thickness corresponding to 0.2% of the thickness of the aggregate layers, the geotextile strip 6 is stretched at a stress rate of 500 MPa balancing the lateral compression of the granular stack . With this percentage of geotextile density compared to the density of the aggregate, the contribution of the grid formed by the glass fibers to the thermal conductivity is almost negligible.
  • FIG. 4 indicates a qualitative appearance of the behavior in vertical compression of the masonry block 1.
  • the first part 16 of the curve corresponds to low forces under the action of which the masonry block 1 is little compressed.
  • This part of the curve 16 ranges between a zero force and a force of 3 MPa.
  • the plasticity of the block is considerable, this appears thanks to the crushing of the light aggregates 5 under an effort between 3MPa and 4MPa, to their rearrangement under strong compression and to the sliding of the geotextile 6.
  • the wall produced with the blocks of masonry 1 can thus perfectly adapt to areas with concentration of stresses such as beam supports or in the event of an earthquake.
  • Under the action of forces greater than 4MPa the masonry block 1 stiffens again thanks to the rigidity of the geotextile strip 6, up to the extreme stress rates corresponding to the rupture of the geotextile strip 6.
  • the vacuum inside the block 1 is balanced with the ambient atmospheric pressure.
  • the behavior in vertical compression is then slightly different from that of the block in depression and is represented by the curve having the reference 17 in FIG. 4.
  • Masonry block 1 is manufactured as follows:
  • the aggregates 5 received by the factory for manufacturing the masonry blocks 1 will be sieved and dried after being possibly crushed so as to have a dry product of controlled density.
  • the casing 2 of the masonry block 1 is produced from an exploded parallelepiped which is cut in a known manner from a complex strip which is impermeable to water vapor and to gases and which is heat-sealable.
  • the exploded parallelepiped has four sides aligned rectangles corresponding respectively to a lateral face 18a, the front face 10a, the second lateral face 18b and the rear face 10b of the parallelepiped envelope 2 of the masonry block 1, and two rectangular faces corresponding respectively to the upper face 7a and to the lower face 7b of the envelope 2 and available on either side of the alignment of the four preceding faces in the vicinity of the face corresponding for example to the front face 10a of the envelope 2.
  • a bag 19 having the shape of a rectangular parallelepiped is formed using a mandrel 20, the upper part 21 of which has the shape and the dimensions of the cavity 3 of the casing 2 of the masonry block 1 from exploded parallelepiped, covering the upper face 22 of the mandrel 20 with the face of the exploded parallelepiped corresponding to the lower face 7b of the casing 2 and covering the four lateral faces of the upper part 21 of the mandrel 20 respectively by the four aligned faces of the exploded parallelepiped.
  • the faces of the exploded parallelepiped corresponding to the faces 18a and 10b of the casing 2 are extended at their opposite ends with flanges 23a and 23b, one of which, 23a is disposed under the lateral face 18a and the other 23b covers the rear face 10b of the bag 19.
  • the free edges of the faces of the exploded parallelepiped corresponding to the upper 7a and lower 7b faces of the envelope 2 are provided with edges 24 and 25 respectively.
  • the parallelepiped bag 19 is placed in a mold 28 comprising a parallelepiped cavity 29 having the dimensions of the masonry block 1 and open upwards, such that the face 7b of the bag 19 covers the bottom of the mold 28, that the faces 18a, 10a, 18b and 10b of the bag 19 cover the internal lateral faces of the mold 28, and that the cover sheet 26 is located outside the mold 28.
  • the five faces 7b, 18a, 10a, 18b and 10b of the bag 19 are pressed against the walls of the mold 28 to 1 using channels 30 formed in the wall of the mold 28, opening into the cavity 29 and connected to a vacuum pump not shown.
  • a metering overflow 31 of aggregates 5 which undergoes a back-and-forth movement between the vertical planes of the front walls 10a and rear 10b of the bag 19 disposed in the mold 28.
  • a reel 34 of a geotextile strip 6 which is movably mounted above the mold 28 between two extreme positions situated beyond the vertical planes front 10a and rear 10b walls of the bag 19 placed in the mold 28.
  • the mold 28 rests by means of elastic elements, such as springs 35 on a frame 36 and the geotextile strip 6 has a width slightly less than the distance separating the lateral faces 18a, 18b of the bag 19.
  • the end 6a of the geotextile strip 6 is disposed in the bottom of the bag 19 and covers the lower wall 7b of the bag 19 by displacement of the reel 34 from the right to the left as seen in FIG. 7.
  • the mold 28 is subjected to vibrations which make it possible to compact the various layers 4a, 4b, 4c formed in the bag 19 located in the mold 28, using a vibration device not shown.
  • the geotextile strip is cut transversely by a knife or a blade not shown, and the cover sheet 26 is folded over the fold upper 6d of the geotextile strip and the rim 24 of the cover sheet 26 is sealed on the upper edge 37 of the side walls 18a, 18b and of the rear wall 10b of the filled bag 19, while retaining an orifice in an upper corner of the casing 2 of the masonry block 1.
  • the interior of the masonry block is placed under vacuum by sucking in the air or the gas contained in the envelope through said orifice, then the orifice is closed by welding.
  • the depth of the mold is slightly less than the height of the bag 19 so as to allow the edge or rim 24 of the cover sheet 26 to be folded against the upper edge 37 of the side walls 10b, 18a, 18b of the bag 19 placed in the mold .
  • the sealing by welding of the edges 23e, 23b, 24 and 25 on the corresponding walls of the bag 19 is carried out in a known manner either by heating or by ultrasound.
  • the implementation of the masonry block is understandable easily.
  • the 20 x 30 x 30 block with a volume of 18 l weighs between 7 and 10 kg.
  • the blocks 1 are stacked and joined by an adhesive mortar.
  • the surface roughness of block 1 depends on the size of the coarse aggregate. This roughness is however corrected and in some way smoothed by the skin of the envelope 2.
  • the outer film 14 of the envelope 2 can be fiberized so as to give the envelope 2 better resistance to tearing and adhesion with the mortar.
  • the block 1 is arranged in the wall in such a way that the portions of strips 8a, 8b and 8c connecting two superimposed folds, for example 6b and 6c of the geotextile strip 6 are vertical and arranged near the faces of the wall.
  • the mason will be able to have a certain number of standard blocks, allowing him to execute the current parts of the structural work, but also the singular parts, such as the supports of slabs and beams, lintels and chaining.
  • the treatment of thermal bridges can be done according to the techniques used in constructions in blocks of autoclaved aerated concrete.
  • the masonry blocks serve mainly as filler material and are subject to low loads
  • Continuous fibers or fibers long enough to be assimilated to continuous fibers, and tensile strength can be randomly placed in the aggregate dose 5 at the time of the aggregates 5 discharge into the bag 19.
  • These continuous or long fibers improve the cohesion of the aggregates in depression in the outer casing 2, are preferably glass fibers, and the masonry block 1 contains about 0.2% glass fibers by volume.
  • the masonry block reinforced by the geotextile strip 6 arranged in folds in the external envelope 2 may also comprise continuous or long glass fibers arranged in layers 4a, 4b, 4c of aggregates 5.
