Definitions

• the object of the present invention is to remedy this drawback and to this end it proposes a method of construction, and structural elements for implementing this method, making it possible to carry out constructions and more particularly walls of constructions, without tools or special equipment, and using only small lifting devices.
• the method of the invention is to transport the known construction of building elements flat, light and occupying only a small volume compre * - "ant only shuttering elements, the metal mesh elements and elements stackable spacing, to mount on each side of the spacing elements a formwork element and a wire mesh element spaced apart to constitute a rigid and self-supporting structure, and to perform the pouring or spraying of concrete or mortar. '
• the wire mesh elements and the casing elements are fixed in a simple manner to the spacer elements, for example by keying, the trellis elements being arranged internally with respect to formwork elements.
• the spacing elements then allow sufficient interior and exterior support of the formwork elements, so as to make the latter stationary for the entire duration of the casting, and they also make it possible to have sufficient fastening elements for the props of maintenance of walls.
• one then uses " lost formwork can possibly be made of cardboard with outside, at a suitable distance, the wire mesh elements of the structure.
• the whole structure thus formed forms a rigid panel which can be connected to similar neighboring panels by ligation of the lattices, these panels then constituting, by projection of micro-concrete, finished walls of the chosen dimension and with the vacuum longed for.
• This vacuum also allows the installation of an insulation either powdery or injected in the form of foam in order to improve the insulation qualities of the construction.
• the vacuum could be filled with heavy materials, powdery clay for example, allowing a thermal inertia effect on the wall rather than insulation.
• the empty ' may also receive stanchions carriers constituting the structure of the constructi
• the spacer elements may be made of round acy, previously formed, forming a portion of the spacer structure of the panels and, for the other part giving the three-dimensional rigidity to the constit assembly with the panels *
• the spacer elements can also be produced from a metal profile of folded and cut sheet metal, for example a U-shaped profile, which provides increased rigidity and can serve as a scaffolding structure before projection of the concrete.
• the spacer elements can also be made of an extruded plastic material, ensuring high insulation of the two sails, but providing less projection of concrete before projection.
• the lost formwork elements can be made of cardboard, inexpensive, light material, sufficiently resistant and which only occupies a small volume for its transport. These cardboard elements can receive no specific impressions (directions for use, traces for both their implementation, location, leveling, alignment, etc ... These cardboard elements - can also receive impressions of specific implementation in c specific sites.
• transverse tube elements playing the role of ani ⁇ elambage meeting bridges. It will be noted that the structure according to the invention, intended to receive the projection of concrete, makes it possible to read very easily all the necessary openings which are to be made in the walls and partitions.
• FIG. 1 is a top view, partially in section, showing a spacer element cooperating with lost formwork elements and with wire mesh elements for the production of a wall with internal void; and
• FIG. 2 is a side view of the spacer device of FIG. 1.
• the spacer element 1 comprises an oblique intermediate part 2 terminated laterally, at each end, by a practically horizontal part 3 -
• Each horizontal part 3 presents outwards portions 4 in the form of loops.
• the lost formwork elements 5 of cardboard, perforated accordingly, are fixed in a vertical position by keying at the inner end of each horizontal part 3 of the spacer element.
• a wire mesh element 6 On the outside of each lost formwork element 5 is arranged a wire mesh element 6 which is fixed, also by keying, at the end of the end portions 4 in the form of a loop of the spacer element 1.
• a self-supporting panel of sufficient rigidity has thus been formed, which can be connected to similar neighboring panels by ligation of the trellis 6, and which allows, by projection of micro-concrete, the constitution of a finished wall of the chosen dimension.
• a virtually continuous vacuum 7 inside which can be passed at will pipes and cables and into which can be easily inserted an insulator (for example pulverulent or injected in the form of foam).
• the construction elements used according to the invention that is to say the cardboard forms 5, the wire mesh elements 6 and the spacers 1 (which can be stacked in a small volume), are light and transportable flat so that the site can be supplied without difficulty, whatever the conditions of access.
• currently known concrete spraying machines can be used at a relatively large distance from the site and are therefore not hampered by possible access difficulties.
• spacers 1 can advantageously be provided . spacers 1 of different lengths, while keeping the same structure, so as to use spacers of the length corresponding to the desired vacuum dimension.
• the spacer elements could also, according to the invention, be articulated on the metal trellis elements. and be attached to them in the workshop.
• the trellis and formwork elements could be delivered flat and simply relaxed on the site thanks to the articulated spacer elements, spacing keys then being used to immobilize the assembly during implementation and prevent it from folds.
