Definitions

  • the subject of the invention is a construction panel made of light insulating material, not very fragile, capable of receiving on each face a final coating, comprising tubular passages parallel to one of the sides of the panel and in which cardboard tubes are arranged. or plastic or the like intended to be filled with concrete.
  • the invention also relates to a method of building construction by the implementation of this panel.
  • FR-A-1 495 245 discloses a construction panel made up of juxtaposed tubular elements. These tubular elements can be filled with concrete to become load-bearing.
  • the major drawback lies in the absence of transverse connections between the tubes, hence an insufficient rigidity of this panel perpendicular to the axis of the tubes, which limits its use.
  • the present invention aims to remedy the difficulties which have just been described, and to provide a panel which combines the qualities of lightness, good insulation, high mechanical resistance with the possibility of a very rapid construction process.
  • the invention as characterized by the claims, provides a panel comprising tubes parallel to each other provided with radial openings on the generators facing each other, so as to constitute transverse passages extending from both sides other over the entire width of the panel so that once the concrete has been poured into the tubular passages, a wall is obtained having a light, almost continuous structure.
  • the invention also provides a method of building construction by juxtaposition along their edges of said panels used as lost formwork into which is introduced as needed reinforced concrete or not after having cut the doors and windows.
  • tubes of cardboard, plastic or similar material to serve as lost formwork has the advantage of offering very great resistance during concreting and vibrating, the circle having the property of making the walls work by traction only; therefore these walls do not need to be very thick where reduction in the weight of the panels, the construction cost and ease of implementation.
  • the advantages obtained thanks to this invention are multiple and allow to quickly build, according to the technique of lost formwork, the basement walls in solid concrete, the storey walls with interposition of insulation on the outside, the walls of separation in light concrete, plaster or any other material.
  • the panels can directly receive the final covering, for example a rustic coating for the exterior and wallpaper for the interior. Cutting out doors and windows in solid walls before concreting greatly simplifies construction.
  • Figures 1 to 3 show, in the three orthogonal views, a panel 1 consisting of two blocks 2 and 3 of expanded polystyrene juxtaposed according to their faces, providing between them parallel hollow cylinders 10 and transverse passages 14.
  • the cylinders 10 are lined of cardboard, plastic or similar material tubes 11 in order to resist vibration of the concrete.
  • the panels are assembled to each other by means of the teeth 12 and 13, which by their alternating male 12 and female 13, per put their casing. Flat joint-tongue and groove joints are also possible.
  • the panel and the cardboard tubes have radial perforations 14 which extend right through the entire width of the panel.
  • the two blocks 2 and 3 can also be molded in one piece from synthetic foam.
  • the radial perforations 14 pass right through the entire width of the panel, from one face to the other.
  • the cardboard, plastic or similar material tubes 11 are perforated radially with the same diameter 14 and spacing as the molded block.
  • the tubes are coated with glue and introduced into the foam block. Expanded by making their perforations 14 coincide with those of the molded block.
  • the cardboard tubes 11a are joined and joined by their generatrices by means of windows 4 and points 5 which fit together according to the principle of the hinge, as shown in Figure 5.
  • a generatrix of the cardboard tube 11a is cut a row of beams 4 leaving between them bridges 5 of height a substantially equal to the height of single windows, however that on the opposite generatrix the height b of the windows 6 is equal to approximately three times the height a of the bridges, so that one single window in three constitutes a transverse passage 15 corresponding with the middle of the opposite window 6 of height triple.
  • FIG. 7 It is also possible to produce a tube-to-tube panel as shown in FIG. 7.
  • the tubes 11a are joined together as described above by sockets according to FIG. 5 and are coated on one side with insulating material 7 and the other of plasterboard 8 or any other similar material.
  • the panels, as described, will be coated with plates or sheets of very diverse composition such as vegetable or mineral fibers with or without the addition of agglomerated glass fibers with the addition of synthetic resins, plaster or cement.
  • a slightly brittle material will be chosen, the surface of which is possibly suitable for receiving a final coating, inside and outside.
  • the tubes can be made of ordinary cardboard, fireproof (phenol) cardboard or synthetic material.
  • Tube to tube panels can, in the case of basement formwork, be made of synthetic material (plastic) and left in their natural state, both indoors and outdoors. It is not necessary to make a waterproof coating because for the exterior these panels are waterproof by themselves.
  • the void between the tubes can be filled by foam injection and on the outer face a coating of insulating material such as expanded polystyrene receiving a rustic coating, the coating panel can follow the shape of the tubes which increases the adhesion surface.
  • the tubes are filled with light concrete, mortar or any other binder.
  • the panel according to the invention which has transverse passages 14 ensuring transverse solidity by continuous connections, it is possible to construct a building according to the process below shown diagrammatically in FIG. 8.
  • planar panels 1 and corner panels la solid walls are mounted by juxtaposition and gluing of panels. Then we cut with a saw the outline of the doors and windows. In the slot left by the saw, a sheet 16 of sheet metal or other material slides. Reinforcement and any pipes are introduced into the empty passages. Concrete is poured into the vertical tubes, this concrete is vibrated to make it flow in the horizontal transverse passages and thus forms uninterrupted horizontal connections. When the concrete has set, the sheets of sheet metal and the cutouts of the doors and windows are removed, and all that remains is to place the frames according to known methods.
