Definitions

  • the present invention relates to the production or reinforcement of floors formed on wooden beams. It applies in particular when such beams can be brought to the site of an existing construction to renovate, transform, or consolidate, such constructions can be for example residential buildings, workshops, walkways or bridges.
  • Its resistant profile is a T-profile, the lower part of which is a wooden beam and the upper part of a concrete slab, generally of compression. This slab was cast on a formwork lost or not, placed on the beams or between them.
  • a distribution trellis made of steel and embedded in the concrete ensures the resistance of the slab to punctures and transverse bending.
  • the composite beams formed by this T-shaped profile are most often simply supported on their ends.
  • This case is the simplest and will be considered below by way of example, it being understood that, if the beams are locally embedded or bear on intermediate supports, the forces are locally reversed.
  • the composite beams work in simple bending.
  • Their neutral fiber is preferably located in the vicinity of the lost formwork, the dimensions of the wood and the concrete being chosen accordingly. Concrete works in compression, wood in tension, in the longitudinal direction, and the connectors support the internal shearing effects which are exerted between wood and concrete in the same direction.
  • the connectors are formed by vertical nails partially driven into the upper faces of the joists through the formwork before the slab is poured. The head and the upper part of each of these nails is embedded in the concrete during this pouring.
  • a floor is described in an article by Godycki et al. "Verbunddecke aus Holzrippen und Betonplatte” (Bauingenieur 59 (1984) 477-483, Springer-Verlag, German Federal Republic).
  • Such connectors have the disadvantage that their middle and lower sections flex easily under the internal longitudinal forces mentioned above. They then tilt in the wood. This bending of the connectors results in deformation of the floor and a reduction in its resistance.
  • the connectors are also metallic and they are rigid. They are formed by connection plates made of sheet metal and extending vertically and longitudinally in contact with the two sides of each beam. Pointed transverse horizontal nailing teeth can be formed by cutting and bending horizontally certain areas of each such plate. They penetrate into the side of the beams to fix the plate during an operation which can be called "nailing". This operation can however also be carried out using ordinary horizontal transverse nails passing through the plate. The upper part of the plate overflows above the beam and is cut to form pointed vertical connection teeth which pass through the formwork when it is placed on these beams and which are then embedded in the concrete of the slab.
  • the object of the present invention is to economically produce a wood-concrete collaboration floor of increased strength. It aims more particularly to produce connectors and to put them into service in such a floor in a simple and effective manner which avoids the drawbacks indicated above.
  • the floor according to the invention comprises certain elements which are analogous to elements of the known floor with rigid metal connectors previously described. These are wooden beams extending in a longitudinal direction and succeeding each other in a transverse direction in a substantially horizontal beam plane, these beams resting on supports for supporting the floor, each of them having an upper face, a face lower and two lateral sides, - a concrete slab formed on these beams to constitute the surface of the floor and participate in the resistance of the latter, - And connectors each embedded on the one hand by a lower section in one of these beams on the other hand by an upper section in this slab, these connectors having a stiffness allowing them, without significant deformation, to transmit between the concrete of said slab and wood of said beams, the internal longitudinal forces which result from the bending loads applied to the floor.
  • the floor according to the invention is characterized in that each of said connectors in the form of a tube, said lower section of this tube occupying a housing hollowed out in the wood of the upper face of a said beam so that this section constitutes, with respect to said internal longitudinal forces, an extended bearing surface of this tube on the wall of this housing and that the stiffness of this tube distributes these forces over this entire bearing surface.
  • This tube will hereinafter be called connector tube.
  • - Said housing and said lower section of said connector tube are made so that the outer wall of this section is in permanent support over substantially its entire surface against the wall of this housing.
  • This housing is made in the form of a groove leaving a core of the wood of said beam.
  • the diameter of said connector tube is sufficient to allow the concrete to penetrate without appreciable segregation into the interior space of said upper section of this tube during the pouring of said concrete slab, so as to reinforce the embedding of this section in this slab after the concrete has hardened.
  • - Said connector tube is made of a material having a higher and / or more homogeneous mechanical resistance than that of the wood of said beams and the concrete of said slab.
  • - Said connector tube has vertical generators and a circular section so as to allow a simple manufacture and to allow an easy realization of its housing in said wooden beam.
  • - Its diameter is between 30 and 130mm and preferably between 40 and 100mm approximately.
  • - Its height is between 6 and 15cm and preferably between 8 and 12cm approximately.
  • - Said lower section of said connector tube penetrates into the upper face of said wooden beam over a fraction less than half the height of this beam.
  • - It has a diameter less than the width of this beam in said transverse direction, and its said lower section remains at a distance from the sides so as to be protected against heat and / or corrosion by a thickness of wood from these sides. This latter arrangement also makes it possible to lay rectangular beams between the beams which rest on the edges of these beams.
  • said beams When producing such a floor, said beams are placed in said longitudinal direction which is horizontal.
  • said connector tubes which are for example metallic. Their lower sections are driven into grooves provided for this purpose in the upper faces of the beams, their axes being vertical. Their upper sections are then embedded in the concrete when the slab is poured. Their role is to prevent the relative horizontal displacement of the wooden beams and the concrete slab when the floor is subjected to bending forces.
  • the floor given by way of example comprises wooden beams or joists such as 2 which can be solid or laminated, and which extend longitudinally as well as their fibers.
  • a lost formwork 4 of known type rests on these beams.
  • a layer of sound and thermal insulation 6 is placed on this formwork, it being understood that this layer can be omitted without loss of the specific advantages of the present invention.
  • a concrete slab 8 is poured on this layer. It is reinforced in a known manner by a metallic distribution trellis which comprises transverse reinforcements such as 10 and longitudinal reinforcements such as 12.
  • the center distance between beams can be from 0.6 to 1.2 m approximately, for example 0 , 7m.
  • Connector tubes 14 extend vertically and each have a lower section 14B embedded in a beam 2, and an upper section 14A embedded in the slab 8 up to, for example, 2 cm from the upper face thereof.
  • the trellis 10, 12 is placed on these connector tubes which makes it possible to maintain its altitude before and during the pouring of this slab.
  • Such connector tubes could also have a non-embedded intermediate section at the level of the formwork 4 and of the insulation layer 6.
  • the formwork 4 and the insulation layer 8 have been drilled with holes 5 which are wider than the connector tubes so that, when the slab is poured, the concrete fills them without segregation on either side of the walls of the connectors 14.
  • the diameter of each hole in the formwork 4 is however sufficiently limited so that the edge of the latter rests on the beam 2 all around the hole.
  • the connector tubes 14 have a circular section of 40 to 100 mm in diameter depending on the span of the beams and a height of 8 to 12 cm.
  • the thickness of the sheet which constitutes them is for example 2mm.
  • the depth of the groove 15 is for example 4 cm.
  • outside and inside diameters of this tool are for example chosen exactly equal to those of the connector tubes, which then requires the application of a moderate vertical force to drive these tubes.
  • the connector tubes are made of structural steel. They could be made of other materials with high and homogeneous mechanical resistance, such as resins reinforced with glass fibers, for example.
  • a vertical slip between the concrete slab and the connector could occur for example in the presence of high frequency alternating loads. It is prevented by simply leaving the saw burrs of the tubes on the upper edge for example. It could also be by welding the reinforcements.
  • cylindrical connector tubes of circular section could be produced in the form of tubes split along a generator so as to be able to easily adapt to housings of slightly different diameters.
