Definitions

  • the present invention relates generally to the prefabricated construction elements used for the construction of different kinds of buildings and it relates more particularly to a composite construction element of the cellular plastic type having metallic reinforcing elements.
  • construction elements are usually composite panels comprising a cellular core of foam material coated for example with a reinforced skin by means of reinforcing elements incorporated therein for example, as described in French patent n ° 1 206 284 which for object a building panel having a cellular foam core coated on both sides with a resistant metal sheet coated with synthetic resin which can itself be loaded and in which all the materials participate in the resumption of forces.
  • Porous lightweight concrete panels are also used, as described in U.S. Patent 2,850,890 having a coating of synthetic resin reinforced with fibers and metal rebar.
  • the aim of the present invention is to produce a self-supporting composite construction element which can be used for the construction of buildings of geometric shapes, for example, pyramidal or parallelepipedal, or in the form of solids of revolution, such as domes, domes, cylinders, or other non-regular shapes by assembling a certain number of identical or different elements adapted to constitute at the same time the frame, or supporting framework, by ensuring the bracing of this one, the closing and the covering of the building .
  • the subject of the invention is for this purpose a composite construction element of the type comprising a body of a foam synthetic material coated with a skin of a plastic material of a different nature and comprising metal reinforcing members, characterized in that it comprises at least two spaced-apart carrier elements each consisting of a metal or other profile entirely contained in a body of cellular plastic material, these carrier profiles being arranged parallel or not and connected together by a web formed by a sandwich formed from a plastic material cellular of identical or different nature to that coating the profiles and of a relatively hard plastic skin, glued, which also envelops the bodies containing the profiles, and assembly means being provided at the ends of said support profiles.
  • the building element according to the invention shown diagrammatically in FIG. 1 has in section the shape of a U having two parallel branches 1a, 1b which are connected by their lower edges by means of a planar web 2.
  • the two wings 1a, 1b being identical, only one will be described.
  • the wing shown in FIG. 2 comprises a metal support profile 3 which, in this example, consists of a vertically disposed iron I, which is enclosed in a body 4 made of a foam synthetic material, preferably a flame resistant phenolic foam.
  • the body 4 is preferably formed of at least two blocks of material machined in shape between which the profile) 3 is disposed without connection. This body 4 is connected along one of its end edges to the end edge of the corresponding wing lb identical opposite al using a web consisting of a plate 5 in a cellular synthetic material, preferably a polyvinyl chloride foam also flame resistant but having good mechanical properties and thermal insulation.
  • the assembly constituted by the bodies 4 and the veil 5 is kept assembled by means of an envelope or skin 6 which is constituted for example by a laminate of glass fibers and polyester resin bonded by polymerization to the cellular materials of the veil and bodies in order to constitute with them a composite sandwich element.
  • This skin is applied by conventional molding methods for example, by means of two half-molds in which the skin is first formed and in one of which the blocks of material are arranged comprising the metal support profiles and the veil , and that one applies to the other to ensure the establishment of all the elements as well as the bonding of the skin on the whole of the element.
  • the metallic support profile 3 preferably comprises an anti-corrosion coating 7 of any type which may be galvanization, metallization, enameling, painting or coating of a synthetic protective resin.
  • Figs. 3A and 3B are views similar to those of FIG. 2 showing two exemplary embodiments in which the supporting sections 8 and 9 have sections of different shapes, for example inverted or tubular enC.
  • each metal support profile do not protrude beyond the skin 6 of the body 4 of sandwich material in which it is enclosed and are preferably covered by this skin, for certain applications they can however be discovered.
  • these fixing and / or connecting means consist of a metal plate 10 or gusset plate which is fixed for example, welded laterally on two corresponding edges of the iron I, the arrangement being such that each plate 10 is immediately adjacent to the skin 6 which envelops the entire element, inside of it.
  • Each plate 10 has several tapped holes 11 which are drilled in the plate through the skin 6.
  • FIG. 4 also shows an example of connection of two self-supporting construction elements according to the invention, end to end, according to which a connecting member designated as a whole is used to connect the ends of the support profiles 3, 3 ′ of the two elements by the reference 12 and which is advantageously constituted by a metal plate which may have two parallel flanges 13 whose spacing corresponds to the height of the wings la and la 'and which is pierced with holes 14 at points which correspond to the holes 11 of the plates 10, 10 'when the elements are in end-to-end contact. It then suffices to introduce screws (not shown) into the holes 11, 11 'tapped on the plates 10 and 10' through the holes 14 and tighten the assembly.
  • end of a building element according to the invention can be fixed for example on a concrete foundation, vertically, using a simple metal bracket (not shown) having in one of its wings holes corresponding to the holes 11 of the plates 10 and the other wing of which can be fixed to studs embedded in the foundation.
  • Fig. 5 shows another embodiment of a construction element according to the invention, this element having the shape of a portion of a spherical sector and being intended for the construction of a building having as a whole the shape of a dome, or spherical cap.
  • This construction element is produced in an identical manner to that described in the previous example, the only difference being that the load-bearing metal sections are not parallel and have identical curvatures so that the edge-to-edge connection of a number of identical elements constitutes a spherical cap.
  • the construction element according to the invention can also have in section the shape of an H, that is to say that the web 5 connecting the wings 1A and 1B can also be attached the latter at an intermediate point of the width of these wings.
  • the construction elements according to the invention are self-supporting, this property being conferred on them by the profiles contained in the wings and which support the loads and ensure the rigidity of the construction carried out.
  • the construction elements according to the invention allow the realization of many types of buildings without any framework or supporting structure, aPParente in a fast and simple way. Without: specialized labor and only using devices for the placement of the panels. For this purpose, hooking members can be used which can be screwed into the threaded holes 11 at the ends of the support profiles.
  • the fixing means can, if desired, be constituted by tapped holes formed directly in one of the lateral parts of the profile which is located adjacent to, or very close to the skin 6, below the latter in each wing of the element.
  • the plates or gussets 10 can be welded to the profile by means of supports of suitable shape in a manner well known to technicians.
  • the cellular material of the body 4 containing the profiles 3 is a foam having high fire resistance properties, -ses mechanical properties is relatively less important.
  • the cellular material constituting the core of the sandwich forming the veils must, on the other hand, have in addition to good mechanical resistance properties, good thermal insulation properties as well as, of course, fire resistance properties satisfying safety standards in force.
  • plastic material reinforced or not, constituting the skin of the sandwich material, for example a polyester resin, can be tinted in order to provide a decorative effect.
  • a polyester resin for example a polyester resin
  • the cellular material constituting the wings and the veil may be the same provided that the material used has the desired properties.
  • the elements according to the invention can, of course, comprise more than two support profiles embedded in bodies made of cellular material linked together by webs and the assembly being coated with the skin, thus constituting a sandwich material.
  • FIG. 6 There is shown in FIG. 6 an alternative embodiment of a construction element according to the invention, more particularly suitable for being used for the construction of large buildings in which the construction elements may have to withstand significant stresses exerted in one direction transverse to the profiles enclosed in the lateral wings, in one direction or the other, that is to say tending to bring the profiles closer to one another (compressive stresses) or tending to move them apart from one other (tensile stress).
  • the element shown in FIG. 6 is of the type having an H section, symmetrical or not, in which the web 25 is connected to the wings 21A, 21B at any point of their width.
  • This element comprises a reinforcing member 30 adapted to withstand the tensile as well as compressive stresses, which can be constituted by a metal or other profile, having any cross-section in shape, embedded in the thickness of the web 25 and whose the ends are in contact with a lateral surface of each of the sections 23, to which can be fixed by any suitable means, for example by welding, bolting or the like.
  • the bodies made of cellular material between which the bearing profiles 23 and the veil 25 are enclosed are made up of separate blocks of different materials or of identical material and the assembly is wrapped and held by the skin 2 6.
  • the reinforcing member or members may be of a flexible nature but preferably relatively inextensible, for example a strip, a cable or the like.
