Definitions

  • the present invention relates to a construction element making it possible, for example, to build a wall or a vertical wall.
  • the document US3885363 A describes a construction element comprising a preformed insulating insert placed in a cavity of a concrete frame.
  • Such construction elements can be used to build a wall by assembling them with mortar for example. This assembly requires precision so that the construction elements are well aligned and time to place the mortar and also because of this precision.
  • An object of the present invention is to provide a construction element that is easy and quick to assemble, and does not require the installation of mortar.
  • the block when two frames are superimposed so that the cavities are aligned, the upper end of the block can be engaged in the cavity of the frame above while the lower end of the block can be engaged in the cavity of the frame below.
  • the block itself serves as a means of fixing and alignment between the construction element and a second element of identical construction. It is therefore not necessary to put mortar between two superimposed construction elements.
  • the fixing between two superimposed construction elements is particularly solid. We can consider that the two frames are fitted snugly onto the block.
  • each block can be retracted as much as possible into the frame during transport, in order to reduce the transport volume and for the block to be at least partially protected by the frame during transport and on the site, before construction.
  • the block remains blocked in the cavity by lateral mechanical compression when it is not subjected to any pressure in a first direction, but it moves relative to the frame when it is subjected to external pressure in the first direction.
  • the block is intended to be fitted snugly into the cavity.
  • the first direction is preferably a vertical direction.
  • the block can for example be made of a compressible material or have a surface structure allowing this movement under pressure and blocking in the absence of pressure.
  • the block is such that the action of a force causes it to slide in the cavity, but if it is not subject to forces other than gravity it is stuck immovable in the cavity.
  • human force is sufficient to slide the block into the frame.
  • external pressure is pressure sufficient to move the block within the cavity.
  • the force corresponding to the external pressure is greater than the force of gravity, so that the block remains immobilized by the frame when it is only subjected to the action of gravity.
  • the external pressure is preferably a pressure in the first direction.
  • the construction element is arranged to weigh less than 20 kg, more preferably less than 15 kg.
  • a prototype of a construction element measuring 300 mm x 300 mm x 300 mm in which the frame is made of OSB and the block is made of expanded polystyrene weighs approximately 4 kg.
  • the frame is preferably an object formed of a plurality of plane walls parallel to the first direction, so as to delimit the cavity in any direction perpendicular to the first direction.
  • Each wall can for example be formed from a panel.
  • the frame is preferably free of grooves on its exterior surface.
  • the cavity is arranged to allow the block to slide from its lower end towards its upper end.
  • the frame can for example be between 100 and 800 mm in height, preferably around 300 mm.
  • the frame can for example be between 100 and 800 mm deep, preferably around 300 mm.
  • the frame can for example be between 100 and 800 mm wide, preferably around 300 mm.
  • the walls of the frame are for example of a thickness between 10 and 30 mm, preferably around 18 mm.
  • the frame can for example be cubic.
  • One function of the frame is to provide the exterior walls of the wall. It also makes it possible to permanently fix several construction elements together so as to form removable modules in relation to each other. A wall can thus be built by placing modules offset from each other, for example staggered.
  • the frame is preferably formed of a thermal insulating material.
  • the upper opening of the cavity is located on an upper end of the frame and the lower opening of the cavity is located on a lower end of the frame.
  • the upper opening of the cavity is identical to the lower opening of the cavity.
  • the block is preferably a solid and solid object.
  • the block is preferably formed in a homogeneous and isotropic material.
  • the block is thermally insulating.
  • the block may for example be made of or include expanded polystyrene, graphitized expanded polystyrene, or polyurethane foam.
  • THE block can for example be in one or more material(s) having a Young's modulus greater than 1.0 GPa, preferably between 2.0 and 4.0 GPa, more preferably between 2.5 and 3.5 GPa.
  • the block is rigid enough to block the frame when partially engaged in the frame cavity.
  • the block is preferably made of a flame-resistant material.
  • the block preferably extends between all the side walls of the frame, so as to be in contact with them.
  • the block is preferably such that it extends between all the side walls of the two frames, so as to be in contact with them.
  • the height of the block is equal to the height of the frame.
  • the block extends laterally between several parts of surfaces forming a triangle, a rectangle or a square.
  • These surface parts preferably comprise a flat part intended to be in contact with the interior surface of the cavity and a recessed part so as to form a chamfer at the upper end of the block.
  • the block can for example be between 100 and 800 mm in height, preferably around 300 mm.
  • the block can for example be between 100 and 800 mm deep, preferably around 263 mm.
  • the block can for example be between 100 and 800 mm wide, preferably around 263 mm.
  • the width of the block is preferably equal to its depth.
  • One function of the block is to form the male part of the arrangement by nesting while the frames form the female parts. Another function of the block is to provide excellent thermal and sound insulation.
  • the cavity and the block are such that the block can enter the cavity through its lower opening and exit through its upper opening. Thus, it is possible to completely slide the block completely out of the cavity.
  • the difference, taken as an absolute value, between at least one lateral extent of the cavity and a corresponding lateral extent of the block measured when the block is outside the cavity is less than 3 mm, preferably less than 2 mm, more preferably less than 1 mm.
  • the lateral extent of the block may be less, greater than or equal to the lateral extent of the cavity, but the difference between these two extents is preferably less than 3 mm, 2 mm or 1 mm.
  • the block is designed to be inserted particularly closely into the cavity.
  • a “lateral extent” of an element can be for example its length, its width, its depth.
  • a lateral extent of the block generally corresponds to a lateral extent of the cavity: for example the width of the block corresponds to the width of the cavity and the depth of the block corresponds to the depth of the cavity.
  • the absolute value of the difference between the lateral extent of the block and the corresponding lateral extent of the cavity is preferably less than 1% of the lateral extent of the block, more preferably less than 0.5% of the lateral extent of the block.
  • the block may be sufficiently compressible laterally so that its lateral extent decreases when it is engaged, at least partially, in the cavity.
  • the difference, in absolute value, between the width of the cavity and the width of the block measured when the block is outside the cavity is less than 3 mm, preferably less than 2 mm, more preferably less than 1 mm and/or the difference, in absolute value, between the depth of the cavity and the depth of the block measured when the block is outside the cavity is less than 3 mm, preferably less than 2 mm, more preferably less than 1 mm.
  • the upper end of the block is chamfered and/or corners of the upper end of the block are rounded.
  • This chamfer makes it possible to reduce the width and/or depth of the block at its upper end in order to be able to easily enter the block into the cavity through the lower opening of the frame, particularly if the lateral dimension of the block outside the cavity is close to the corresponding lateral dimension of the cavity.
  • the chamfer can, for example, be approximately 1 cm.
  • the frame comprises side walls delimiting the cavity laterally, and the block is provided to be in mechanical contact with all the side walls of the frame when it is blocked, at least partially, in the cavity.
  • the block is in mechanical contact with all the side walls over at least 50% or 80% of the height of the block which is in the cavity.

  • the horizontal section of the frame and that of the block are preferably rectangular, more preferably square.
  • the cavity is delimited by flat surfaces parallel to the first direction.
  • the flat surfaces which delimit the cavity are not inclined relative to the first direction. This notably avoids any shrinkage of the cavity upwards or downwards.
  • the frame is at least partially made of wood and/or polymer.
  • the frame can be made of any material including wood.
  • it can be made from called oriented strand board, which is sometimes known as OSB. MDF is also possible.
  • the frame can also be made of a polymer.
  • the frame does not include concrete.
