Definitions

  • interlocking blocks can serve as formwork for the compression slab that covers them.
  • interlocking blocks have a load-bearing role or not. They also help to enhance the performance of a floor, for example, thermal or sound insulation.
  • the invention aims to obtain a concrete beam floor with preserved mechanical properties while reducing the use of non-renewable raw materials, in particular steel, and reducing its carbon footprint.
  • the invention provides a concrete floor comprising the characteristics of claim 1.
  • the connecting element is formed from a wooden strip which extends along a main longitudinal axis and which has a lower face for fixing to the beam and an upper face for contact with the concrete slab, the wooden strip comprising hollows produced by removal of material in its upper face into which the concrete of the slab is poured, the generally transverse walls delimiting the hollows being capable of transmitting the shear forces exerted generally longitudinally by the slab on the wooden strip during bending of the floor.
  • This feature ensures that the concrete slab remains fixed to the beams even in the event of significant flexion of the floor. In particular, it prevents the concrete slab from slipping relative to the beams.
  • the hollows are formed by grooves which extend generally transversely.
  • Such hollows are easy, quick and inexpensive to make on wooden slats.
  • the wooden strip is delimited by at least two edges which are provided with means to resist vertical tearing of the slab relative to the wooden strip.
  • the means for resisting tearing are formed by grooves which extend longitudinally and into which the concrete of the slab is poured.
  • grooves are easy, quick and inexpensive to make on wooden slats.
  • the means for resisting tearing are formed by a beveled shape of the edges.
  • the beam is made of soft wood, while the wooden strip is made of hard wood.
  • the wooden strip is fixed by gluing its lower fixing face to the upper face of the beam.
  • the lower face of the wooden blade attachment comprises longitudinal relief slots which make it possible to absorb the dimensional variations of the beam depending on the hygrometric conditions.
  • the wooden strip is fixed to the beam by screwing or nailing.
  • the floor comprises at least one wooden strip whose main longitudinal axis extends parallel to the main axis of the beams, called a stringer.
  • At least one beam comprises a spar which extends substantially over the entire length of the face upper part of the section of the beam intended to receive the concrete slab.
  • At least one beam comprises several side members which are distributed in an aligned manner over the entire length of the upper face of the beam intended to receive the concrete slab.
  • This feature allows part of the slab's support function to be carried out using wooden slats. This allows, in particular, to reduce the dimensions of the metal frame, and therefore the quantity of metal present in the floor.
  • the wooden slats are treated with a water-repellent product.
  • This feature prevents the water present in the concrete during the pouring of the slab from being absorbed by the wooden slats.
  • the wooden slats are protected against rotting, while the concrete retains its mechanical characteristics, including at the interface with the wooden slats during setting.
  • longitudinal, vertical and transverse orientations will be adopted without limitation.
  • the longitudinal and transverse directions are applied locally for each wooden strip 32.
  • the vertical direction is indicated by the arrow "V” in the figures which is conventionally oriented from bottom to top.
  • the term "horizontal” will be used to designate a plane parallel to the upper longitudinal transverse face of the floor slab, the vertical direction extending orthogonally to the horizontal upper face of the slab.
  • the vertical direction often corresponds to the direction of gravity, however the invention is also applicable to floors intended to be inclined relative to the direction of gravity.
  • the concrete floor 10 comprises at least one beam 12 having a main axis "X".
  • Each beam 12 here has a rectangular cross-section.
  • each beam 12 is delimited vertically by an upper face 14 and a lower face 16, and transversely by two lateral faces 18.
  • each beam 12 generally comprises two end sections 20 which are intended to allow it to rest on supports 16 and a central section, called the span section 22, which is intended to extend between the two supports 16.
  • the support 16 can be formed by the level of a wall 23, by a support beam, called a sail working at the belt fixed to a wall 25, as shown in the Figure 5 , or a metal shoe (not shown) which is fixed to a wall.
  • the floor 10 has several beams 12, as shown in figures 1 And 2 , they are preferably arranged in parallel.
  • Floor 10 here has four identical beams 12. They are spaced transversely at a spacing "E" relative to the axis "X" of the beams 12.
  • the beams can be arranged in a manner which is not parallel to each other.
  • the floor 10 also has a concrete slab 24 which is poured so as to rest on the upper face 14 of the beam 12.
  • the concrete slab 24 has the shape of a plate which is delimited vertically by an upper horizontal floor face 26 and a lower horizontal floor face 28.
  • the slab 24 has a substantially constant vertical thickness, for example between 4 cm and 10 cm, preferably approximately 7 cm. In general, the slab 24 rests on the span section 22, while the end sections 20 protrude on either side of the slab 24.
  • the slab 24 is here reinforced by a metal reinforcement 30 which is taken into the concrete constituting the slab 24.
  • the reinforcement 30 is shown in broken lines at figure 1 and it is visible on the exploded view shown in the figure 6 Here it presents the form of a grid-like lattice formed by crossing metal rods, particularly steel.
  • the beam 12 is made of wood.
  • This is, for example, a soft wood, such as coniferous wood, in particular spruce.
  • Such wood has mechanical properties that are entirely suitable for construction, in particular in terms of breaking strength and elasticity.
  • the use of a wooden beam 12 instead of a reinforced concrete beam, as is the case in the prior art, is a solution with numerous advantages, in particular from the point of view of environmental protection.
  • the softwood of the beam 12 risks absorbing the moisture contained in the concrete when the slab 24 is poured. This risks causing a structural disparity in the slab 24, the areas dried out too quickly by absorption of water being less resistant due to poor setting of the concrete than the areas where the water has evaporated more slowly. In addition, the water absorbed by the beams 12 risks causing play and, ultimately, causing fungal degradation to start in the softwood and thus significantly reducing the breaking strength of the beam.
  • Connecting elements are also made of wood.
  • this is wood treated to resist moisture, particularly by means of a water-repellent treatment.
  • These are, for example, connecting elements made of hardwood, such as beech or oak.
  • the water-repellent treatment is carried out, for example, by applying one or more layers of a water-repellent product such as a varnish, possibly preceded by the application of a primer.
  • the wooden blade 32 has a lower horizontal face 34 for fixing to the beam 12 and an upper face 36 for contact with the concrete slab 24.
  • the wooden blade 32 has lateral edges 38 which extend longitudinally and which join its lower face 34 to its upper face 36.
  • the vertical thickness of the blade is generally much less than the dimensions of its lower and upper faces 34, 36, for example of the order of a centimeter.
  • the wooden blade 32 is more particularly intended to be taken into the concrete of the slab 24 over its entire thickness so that its lower face 34 is flush with the lower face 28 of the slab 24.
  • the invention thus makes it possible to increase the bending rigidity of the floor 10 by associating the wooden beam 12 subjected to tension with the concrete slab 24 subjected to compression by means of the wooden blade 32 forming a very rigid connection element.
  • the lateral edges 38 are here provided with grooves 42 which extend longitudinally.
  • the concrete of the slab 24 is poured into the grooves 42.
  • the grooves 42 are capable of transmitting orthogonal loosening forces to the slab 24 as far as the wooden strip 32 in order to prevent the slab 24 from being torn away from the wooden strip 32.
  • At least one wooden blade 32 which extends parallel to the main axis "X" of the beams 12, is called a stringer 32A.
  • the side members 32A are intended to be fixed directly to the upper face 14 of each beam 12 in order to guarantee good fixing of the slab 24 to each beam 12.
  • the side members 32A advantageously have the same width as the upper face 14 of the beam 12. They are here arranged so that their lateral edges 38 are in the extension of the lateral faces 18 of the beams 12. Thus, the shear forces applied to the side members 32A during bending of the assembly formed by the beam 12 and the slab 24 are distributed over a larger surface area.
  • a beam 12 comprises several longitudinal members 32B which are aligned on the upper face 14 of the beam 12 which is intended to receive the slab 24.
  • the longitudinal members 32A of the same beam 12 are arranged at a longitudinal distance from each other, with a regular interval "I", over the entire length of the upper face 14 of the beam 12 which is intended to receive the slab 24.
  • the hollows 39 are distributed regularly on the upper face 36 of each longitudinal member 32A.
  • the side members 32A are distributed unevenly, with a greater density near the end sections 20, the density gradually decreasing as one approaches the middle of the span section 22. Indeed, the shear forces "C" are much greater near the end sections 20 bearing on the supports 16 than in the middle of the span section 22 of the beam 12.
  • each beam comprises a spar which extends substantially over the entire length of the upper face of the beam which is intended to receive the slab.
  • the hollows, in particular grooves can then be distributed regularly over the entire length of the spar, or according to a gradual distribution in which the hollows, in particular the grooves, are arranged with greater density near the end sections 20, the density gradually decreasing as one approaches the middle of the span section 22.
  • the 32A beams and the 12 beams are made of different types of wood which react differently to hygrometric variations.
  • the 12 beams made of soft wood are particularly likely to have dimensions which vary with a greater amplitude than the 32B hardwood beams depending on the hygrometric conditions, which are dependent on humidity and temperature.
  • the lower face 34 for fixing the spar has longitudinal discharge slots 44 which make it possible to absorb the dimensional variations of the beam 12 depending on the hygrometric conditions, as illustrated in figure 7 .
  • each crosspiece 32B is arranged across the beams 12.
  • a crosspiece 32B rests on several beams 12. More particularly, each crosspiece 32B is arranged in the interval "I" reserved between two longitudinal members 32A of each beam 12. Thus, the crosspieces 32B are located in the same horizontal plane as the longitudinal members 32A.
  • the lower fixing face 34 of each crosspiece 32B is arranged directly in contact with the upper face 14 of each beam 12.
  • the crosspieces 32B are preferably fixed to the beams 12 by screwing or nailing. Alternatively, the crosspieces are fixed to the beams by gluing.
  • This grid arrangement of the side members 32A and the cross members 32B thus makes it possible to provide good support to the slab 24. This at least makes it possible to reduce the section of the metal rods used to form the frame 30.
  • the floor 10 may also include interjoists 46 which are inserted into the spacing "E" between two beams 12.
  • the beams 12 are also equipped with means for supporting the interjoists 46.
  • This is a wooden board 48 fixed flat under the lower face 16 of each beam 12.
  • the board 48 has a width greater than that of the beam 12 so that two lateral strips 50 of the board 48 protrude laterally on either side of the beam 12 to serve as support for the interjoists 46.
  • Each board 48 is fixed to the beam 12, for example by gluing if it participates mechanically in the longitudinal behavior, by nailing or by screwing.
  • the board 48 can be made of hardwood or softwood depending on the desired strength.
  • each side member 32B is fixed to the upper face 14 of each beam 12.
  • the side members 32A are, for example, glued by their lower fixing face 34 to the upper face 14 of the associated beam 12.
  • the board 48 is positioned and fixed against the lower face 16 of the beam 12. This gives the structural element shown in figure 15 .
  • the beams are possibly connected to each other by crosspieces 32B.
  • each skirt 56 is arranged so as to cover an associated lateral face 18 of the beam.
  • the upper face 14 is in fact protected by the side members 32A and by the water-repellent treatment, while the lower face 16 is protected by the boards 48.
  • the protective skirts 56 can also be used to create formwork for the concrete slab 24 as will be explained later.
  • the beams 12 are positioned in the structure, then they are fixed in place, as shown in figure 19 .
  • the skirts 56 are raised, then interjoists 46 intended to form a formwork are arranged in the spaces "E" reserved between two adjacent beams.
  • the interjoists 46 rest on the strips 50 of boards 48 which protrude from the two beams 12 on either side of the space "E".
  • the skirts 56 are then folded flat onto the upper surface of the interjoists 46 and fixed edge to edge, for example by adhesive strips, to produce a waterproof horizontal surface 62 which is flush with the upper face 14 of the beams 12 for the purpose of pouring the slab, as illustrated in figure 20 .
  • crosspieces 32B are then arranged across the beams 12, over the horizontal waterproof surface 62, then fixed to the beams 12, as illustrated in figure 21 .
