Definitions

  • the present invention relates to a method of building walls, including walls without bricks with a self-supporting formwork and insulation, and a wall constructed according to this method.
  • formwork techniques is well known to overcome the use of bricks when erecting walls.
  • This technique involves pouring concrete into the space formed between two vertical walls formed by the assembly of prefabricated panels; Among other things, it makes it possible to install different types of ducts intended for sanitary installations, electrical installations, etc. before pouring concrete, avoiding drilling steps that can be tedious when the wall is already built, including to determine the most appropriate places where to start and finish the ducts.
  • Insulating forms use this technique to obtain good thermal insulation properties with the advantage over traditional techniques of easier assembly and a lighter structure. Furthermore, the fact of performing the insulation operation together with the construction of the house without requiring a subsequent step results in a significant decrease in construction costs.
  • the formwork panels made of an insulating material, are intended to remain permanently against the outer and inner faces of the walls after pouring the concrete. In this case, we generally speak of a formwork of the lost type.
  • the insulating walls are formed of a regular assembly of elementary panels, which are fixed the others for example by means of fasteners with screws or rivets, or by a tongue-and-groove interlocking. In order to guarantee a better sealing of the wall, the panels can also be glued at the joints of assembly.
  • the panels are often profiled to facilitate their horizontal assembly; the patent EP0374064 describes for example a formwork technique using profiled panels of complementary shapes of the male female type for forming lap joints at the longitudinal interfaces.
  • guide rails can be provided at the base of the wall, where the forces are greatest, to ensure better stability. Such rails are described for example in the patent EP1061193 . Stays can also be provided and horizontal rules to maintain the verticality of the walls despite the thrust of the concrete, as described in the patent FR2754285 .
  • the fastening or reinforcing elements are often embedded during pouring of concrete and lost with the rest of the formwork structure.
  • the document FR2720426 describes for example a lost formwork structure containing spacing profiles screwed to the panels and intermediate longitudinal rails before pouring the concrete.
  • the document DE2144523 discloses a formwork technique using struts 13 and fasteners 18 between the panels; these fasteners are embedded in resin concrete.
  • the document DE2228967 relates to a wall structure formed by shuttering panels held by bars 3 then embedded in concrete.
  • the document EP0491394 relates to a formwork system in which reinforcing rods are lost in the concrete.
  • An object of the present invention is to provide a system and a method of construction free from known limitations of the state of the art.
  • an object of the invention is to provide a self-supporting insulating formwork structure in which a minimum of building elements are required apart from the formwork panels, and whose construction is simple and practical.
  • Another object of the invention is to provide a faster method of assembling the formwork walls and dispensing reinforcing elements in particular at the corners of the building through the use of new tools.
  • the method according to the invention is characterized by a step of removing the clamping pieces 9, the retaining plates 8 and the rod 6 after said concrete has hardened.
  • the spacers are lost in the resulting final structure consisting of formwork walls 3,4 and concrete.
  • the figure 1 illustrates a perspective view of a wall erected according to the method of the invention.
  • the Figure 2a and 2b respectively illustrate a sectional view of a wall erected according to the method of the invention, under construction, and a front view of the retaining plates and clamping pieces.
  • the figure 3 shows the specialized tools used for the assembly of the walls.
  • the figure 4 illustrates the additional scaffolding tools according to a preferred embodiment of the invention.
  • the figure 1 illustrates a preferred embodiment of the realization of a wall according to the method of the invention, showing all the building elements apart from the concrete.
  • the formwork elements are panels 1 provided with profiled slices 16 by grooves and ribs facilitating their mutual interlocking. Although only vertical grooves are visible in the figure, those skilled in the art will understand that the use of profiled slices 16 is also conceivable for the horizontal assembly of the panels 1.
  • the outer wall 3 is insulating; however, it is possible to envisage that the internal form wall 4 is insulating, or even that the two walls 3 and 4 are both insulating.
  • the material used for the insulating wall 3 is, for example, expanded polystyrene (for example SAGEX), the cutting of which of any geometrical shape is relatively easy, a characteristic which may prove useful for the formation of doorways. or windows.
  • any other type of rigid insulating material may also be retained for the outer wall 3.
  • the inner form wall 4 may be mounted for example with rigid prefabricated panels 2 made of a material based on plaster and / or agglomerate bonded to cement, or with wooden panels, for example with OSB thin oriented slats.
  • This wall may also be coated with an insulating material and / or contain a complementary insulating coating, for example on the inner face of the wall intended to adhere to the concrete.
  • the size of the spacers 6, illustrated in more detail later on figure 2 can also be adjusted according to the desired thickness of the walls.
  • the panels are simply glued to each other, without requiring fasteners between the panels 1.
  • the method of gluing with the special tools is described later on the basis of the figure 3 .
  • the resulting wall thus comprises no reinforcement element.
  • Reinforcing lattices (not shown) can also be added for example for the walls located in the ground.
  • formwork elements 1 ' preferably also insulating, are located under or against the external formwork wall 3, itself also insulating, and serve as formwork for the edges of the formwork.
  • the insulating formwork elements for the edges of raft 1 ' are slightly different from those used for the outer wall 3; they are generally denser and less thick.
  • a preliminary step of digging a super-depth around the raft 17 is necessary.
  • the figure 2a illustrates a sectional view of a building wall using the construction method of the invention, before the clamping pieces 9, the retaining plates 8 and the rod 7 are removed.
  • the rod 7 is threaded and the clamping pieces 9 are nuts.
  • This variant has the advantage of being able to fine-tune the tightening.
  • this embodiment should not be interpreted in a limiting manner; it is for example possible to use pins of any section (cylindrical, square) or a cotter pin which for example would separate branches at opposite ends of the holes for clamping and fixing.
  • the clamping pieces 9 can also for example consist of plugs driven on the ends of the rod 7.
  • the rods 7 are introduced into the holes 5 and the spacers 6 are threaded along the rod 7 between the walls 3,4.
  • the retaining plates 8 are threaded along the rod 7 on the outside of the walls 3,4 before or after this step, and the nuts 9 screwed up to feel the retention of the spacers 6.
  • the figure 2b shows a front view of the retaining plates 8 - here in the form of disks - and nuts 9.
  • the plates can take any other geometric shape easy to machine (for example, square or rectangular).
  • the number of retaining plates 8 will preferably be greater towards the bottom of the wall, where the pressure is greatest. strong.
  • an alternative variant (not shown) to the wall illustrated by the figure 1 may provide that the walls are erected on base rails.
  • the figure 3 illustrates a preferred mode of assembly of the wall 3, preferably insulating, by gluing and the special tools that are used to do this. It is possible to distinguish the plates provided with tips 11 which are inserted into the formwork elements 1, preferably insulating, and thus maintain in mutual compression their adjacent slices.
  • the adhesive used can also be expansive, in which case the plates also serve to retain the thrust during the drying of the glue.
  • the plates provided with spikes 11 are used for the slice-to-slice assembly of the shuttering elements 1 to form a wall section; they make it possible to dispense with any fastening element between the formwork elements 1.
  • these tools illustrated on the figure 3 consists of a bracket 12 provided with tips whose end is a profiled spring metal plate 13.
  • This bracket 12 serves the same purpose of keeping two formwork elements 1 in compression as the plates 11, but applies to angulated parts of the wall to be built, the angle represented here being right according to the figure 3 .
  • These brackets therefore act as clamps for these angled parts.
  • the walls are assembled according to the preferred embodiment corresponding to the illustration of the figure 1 , in which formwork elements 1 'are added under or against the insulating outer wall 3 at right angles in order to form the edges of the slab 17.
  • the assembly described in this figure corresponds to the preferred embodiment of the slab formwork 17 illustrated by the figure 1 , on which it can be seen that the slices of the shuttering elements 1 'are glued to the shuttering wall 3; however it is also possible to consider sticking the lower slices of the wall 3 on the side of formwork elements 1 '.
  • the formwork technique according to the invention can also be advantageously used to realize the door and window embrasures, by covering the concrete slices with shuttering elements 1, preferably insulating, then by sticking these insulating elements 1 on those of the outer wall 3.
  • the brackets 12 make it possible to maintain the compression during the gluing and are therefore a preferred tool to ensure insulating formwork also at the embrasures.
  • FIGS. 4a and 4b respectively illustrate a front view and profile of other new tools that are used to facilitate the construction according to a preferred embodiment of the invention.
  • Vertical assembly rules 14 can be distinguished, situated according to the embodiment illustrated on the internal form wall 4 of the wall. Similar assembly rules 14 are preferably used together on the outer form wall 3 to allow mutual cooperation.
  • the assembly rules 14 comprise holes (not referenced), for example regularly spaced, and preferably with a doubling of the number of holes in the lower part to be able to fix more retaining plates 8 and thus better withstand the pressure of the concrete, as explained previously. However, they are only intended for temporary use as scaffolding and not as reinforcement.
  • the rulers 14 will preferably be threaded vertically along a series of rods 7, behind the plates 8 to thereby consolidate the entire building by rows of retaining plates 8.
  • the clamping pieces 9 are preferably fixed directly on the rulers
  • this embodiment should not be considered as limiting and the aforementioned parts can be threaded in a different order.
  • retaining plates 8 may be used together with the assembly rules 14 for the erection of the internal formwork walls 4 or external 3, or both.
  • props 15 are used parallel to ensure the vertical formwork walls 3,4, and if necessary readjust. These struts 15 may for example be screwed onto the floor 17.
  • the struts 15 differ from those of the prior art in that they are preferably hollow in order to facilitate the step of drilling holes 5, which are made then in the alignment of the holes of the assembly rule 14.
  • the construction method according to the invention also makes it possible to guarantee an insulating formwork for the slab heads (not shown). for example by choosing a formwork outer wall height 3 slightly greater than that of the inner wall 4, a thickness preferably about equal to that of the slab.
  • the described construction method makes it possible to guarantee a reduction of the work necessary for the construction by avoiding the formation of recesses, sheathings, reweaving, concreting of openings, etc. which constitute construction works in general very expensive.
  • the ease of assembly of walls 3,4 and wall mounting minimizes labor costs on site by reducing the time required for building construction by approximately 20%.
  • the new tools used for the assembly of the walls make it possible to minimize the reinforcement elements required for the construction of the wall; once poured concrete, a priori only spacers 6 are lost as building elements, but clamps and all other fasteners are reusable.
  • This modularity is practical to realize different types of walls, different thicknesses, without requiring the use of different tools each time.
  • the thermal insulation provided by the construction method according to the invention is very good since all thermal bridges are removed from basements to the roof, including the embrasures and slab heads on each floor. These insulating properties are very important to guarantee the award of Minergie and Minergie Plus quality labels.
