Definitions

  • This presentation relates to a building element, in particular a building element that can form all or part of a floor, a staircase or a wall.
  • the present presentation relates to such a construction element of the type comprising at least a first and a second sheet superimposed at a distance from each other, in a direction of superposition, and means for fixing the first and second sheets between them, arranged between said sheets.
  • Floors, stairs or walls are today made of a wide variety of materials and in particular noble materials, for example transparent glass or lacquered glass, to give an architectural style to the building, to increase the luminosity of the rooms, or even to allow a visibility between different rooms or levels of a building.
  • noble materials for example transparent glass or lacquered glass
  • a typical 200 glass floor is shown as an example in the figure 1 .
  • the floor is formed by juxtaposition of construction elements 110 each comprising the superposition of a lower sheet of glass 112 and an upper sheet of glass 114.
  • Each building element 110 is typically supported at its periphery by one or more support brackets 190 generally made of metal, to which the lower glass sheet 112 is often adhered by means of an adhesive 194.
  • a seal 180 is formed between the edge of the upper glass sheet 114 of a building element 110 and the edge of the upper glass sheet 114 of an adjacent building element 110.
  • the facing faces of the lower and upper glass sheets of the same construction element are held at a distance from each other by spacers 170, and fixed directly to each other by means of a cord of glue 130.
  • This transparent sheet must therefore be changed regularly.
  • this change requires time and manpower: the seal between the various construction elements must first be removed. Then the bead of glue between the two transparent sheets is cut. For this, it is necessary to break the upper transparent sheet beforehand, which can also prove to be dangerous.
  • the document FR1469605A discloses a construction panel comprising at least two superposed rigid walls fixed to each other by their periphery.
  • One of the objectives of the present invention is to provide a construction element of the aforementioned type making it possible to solve the aforementioned problems, and in particular allowing a quick and safe change of one of the sheets forming the construction element.
  • a construction element for a floor, staircase or wall comprising at least a first and a second sheet superimposed at a distance from each other, in a direction of superposition, and means for fixing the first and second sheets between them, arranged between said sheets
  • the construction element being characterized in that the fixing means comprise at least one retaining element fixed on the first sheet and at least one adhesive product adhering to the second sheet, the the retaining element forming a receiving groove that can be filled by the adhesive product in an uncured state and having at least one anchoring part adapted to retain the adhesive product in a cured state, the retaining element and the adhesive product each being made of a material such that the adhesive product in the hardened state can be extracted from said groove without damaging the retaining element.
  • the two sheets can easily be attached to each other: the retaining element, attached to one of the sheets, retains the adhesive product which has hardened inside its groove and additionally adheres to the another sheet, against a lateral displacement (i.e. which would cause a lateral sliding of the transparent sheets) and a transverse displacement (i.e. which would cause a spacing/separation of the two transparent sheets).
  • the adhesive product is a product suitable for pass from an unhardened state in which it can be introduced inside the groove conforming to the profile of said groove, to a hardened state in which it has sufficient cohesion and rigidity to be mechanically retained by the anchoring part of the retaining element when a tensile force is applied to it away from the retaining element.
  • the adhesive product is in pasty form in the uncured state and becomes an elastomer in the cured state.
  • the hardening of the adhesive product can result from a chemical reaction or from cooling.
  • the chemical reaction is in particular a polymerization and/or crosslinking reaction initiated by at least contact with humidity in the air, heating, radiation, or a mixture between two previously separated components.
  • At least one of the retainer and the adhesive in the cured state is flexible or soft
  • at least one of the retainer and the adhesive in the cured state, and in particular each of them, is made of a material having a Shore A hardness of at most 70, in particular between 30 and 60, or even between 50 and 60.
  • the retaining element and the adhesive product in the cured state do not adhere to each other in a way that would prevent their detachment.
  • the retaining element is based on a thermoplastic polymer material, for example polyvinyl chloride (PVC) or polypropylene (PP), or based on an elastomer, in particular a thermoplastic elastomer based olefin (TPE-O), for example comprising a mixture of polypropylene and EPDM rubber.
  • a thermoplastic polymer material for example polyvinyl chloride (PVC) or polypropylene (PP)
  • PP polypropylene
  • TPE-O thermoplastic elastomer based olefin

  • a curable polymer in particular a polyurethane or a silane-modified polymer (in particular a silane-modified polyether or a silane-modified polyurethane) or a polysiloxane.
  • a particularly preferred combination of materials is an olefinic thermoplastic elastomer for the retainer and a polyurethane for the adhesive product.
  • the first sheet and/or the second sheet is made of a transparent material.
  • a transparent material should be understood here as a material having the property of allowing light to pass. It can therefore be truly transparent (in the sense that one can clearly distinguish objects through it) or translucent.
  • the first or the second sheet can also be made of an opaque material (for example opaque glass).
  • the first sheet and/or the second sheet is made of glass.
  • each sheet can also be made of a plastic material, a combination of glass and plastic or any other suitable material.

  • the first and the second sheet have dimensions, measured perpendicular to the superposition direction, which are substantially identical, in other words which differ by at most 10% (the width of a sheet is equal to at most 1.1 times the width of the other sheet and in the same way the length of one sheet is equal to at most 1.1 times the length of the other sheet), preferably by at most 5%.
  • the first and the second sheet face each other, in the overlapping direction, over at least 80%, preferably over at least 90%, of the extent of one of the first and the second sheet.
  • the first and the second sheet face each other, in the superposition direction, over the entire extent of one of the first and the second sheet.
  • the two sheets have identical dimensions, and are arranged so that their edges (edges) face in a direction orthogonal to their main faces.
  • the fastening means typically arranged at the edge of the first and second sheets, generally delimit a solid and continuous intermediate space between the first and the second sheet.
  • the intermediate space is delimited by the first and the second sheet in the direction of superposition, and, laterally, by the interior side of the retaining element(s) and the adhesive product.
  • the intervening space typically has a generally rectangular extent, in section in a plane orthogonal to the direction of superposition.
  • the retaining element forms a continuous frame closed on itself, and the adhesive product forms a continuous adhesive bead over the entire length of the frame, delimiting an intermediate space between the first and the second sheet.
  • sealing means are provided between the first and the second sheet, ensuring the sealing of this intermediate space.
  • the building element further comprises moisture absorption means suitable for absorbing moisture inside the intermediate space.
  • the construction element comprises, inside the intermediate space, a profile forming a continuous frame and closed on itself, filled with a material with moisture absorption properties.
  • the construction element further comprises, at a distance from the retaining element, at least one spacer placed between the first sheet and the second sheet.
  • the construction element comprises a plurality of spacers distributed in the intermediate space at a distance from the retaining element.

  • the construction system comprises the juxtaposition of at least a first and a second construction element as defined above.
  • a seal is formed between a sheet of the first construction element and a sheet of the second construction element.
  • the invention finally relates to a method for maintaining a construction element, in particular for a floor, staircase, or wall, as defined above, in which a tensile force is exerted on at least one of the first and second sheet in the overlapping direction, away from the other sheet, whereby the cured adhesive product is extracted from the receiving groove, without damage to the retainer, and the first and the second sheet are separated l each other.
  • the tensile force is for example exerted by means of at least one suction cup, preferably placed at a corner of the construction element.

  • the sheets coincide and face each other over their entire extent. Their edges (edges) are aligned in the direction of overlap Z.
  • the external faces 14b of the second sheets 14 constitute the upper face of the floor 100. This is directly subjected to wear linked to the normal use of the building (passage of users, shocks linked to falling objects, etc.).
