Abstract
Description
L'objet de l'invention a pour but la réalisation d'ouvrages en béton en se servant de panneaux métalliques adaptés de façon particulière permettant la mise en oeuvre du procédé. The object of the invention is to produce concrete structures using specially adapted metal panels allowing the implementation of the process.
Le procédé de réalisation d'ouvrages en béton de l'invention est du type comportant des maillages externes à travers lesquels l'ouvrage est réalisé par un coulage de béton frais ou par application de mortier ou de plâtre sur ses faces. The process for producing concrete structures of the invention is of the type comprising external meshes through which the structure is produced by pouring fresh concrete or by applying mortar or plaster to its faces.
Différents procédés de construction existent permettant de réaliser des ouvrages de bâtiment. Different construction methods exist which make it possible to carry out building works.
La technique fait appel à une structure interne métallique sur laquelle on agrafe des grillages aciers afin de créer les supports permettant la mise en place du béton ou l'application d'enduits. The technique uses an internal metallic structure on which steel mesh is stapled in order to create the supports allowing the placement of concrete or the application of coatings.
L'inconvénient de ces procédés c'est qu'ils font appel à différentes phases d'interventions longues et coûteuses. The disadvantage of these methods is that they use different phases of long and expensive interventions.
L'invention a pour objet de résoudre ces difficultés. The object of the invention is to solve these difficulties.
Le procédé de l'invention du type général, ci-dessus mentionné, se caractérise par les étapes successives suivantes: - on met en place, sur le lieu de la construction, une structure composée de deux panneaux de lattis métalliques nervurés, étirés et ajourés à mailles fines dont un de ces lattis ajouré à mailles fines présente des ondes répétitives suivant un entraxe donné. Ces deux panneaux étant appliqués l'un contre l'autre et fixés au moyen d'agrafes métalliques, - on coule du béton dans le volume de cette structure entre les deux surfaces de lattis. The process of the invention of the general type, mentioned above, is characterized by the following successive steps: - a structure is put in place, on the place of construction, made up of two ribbed, stretched and perforated metal lath panels with fine meshes of which one of these openwork lattices with fine meshes presents repetitive waves according to a given center distance. These two panels being applied one against the other and fixed by means of metal staples, - concrete is poured into the volume of this structure between the two lath surfaces.
Le lattis présentant des ondes répétitives peut épouser n'importe quelle courbe désirée grâce à l'articulation de ses ondes. The lattice with repetitive waves can follow any desired curve thanks to the articulation of its waves.
Le lattis, non modifié, utilisé dans le sens vertical de son nervurage, peut-être courbé naturellement, suivant ainsi la forme de la structure composée, et créé tous les types de parois droites, courbes ou angulaires d'un bâtiment. The lath, unmodified, used in the vertical direction of its ribbing, can be bent naturally, thus following the shape of the composite structure, and creates all types of straight, curved or angular walls of a building.
Il est possible de rigidifier l'ensemble dans la forme définitive en incorporant des armatures métalliques qui vont traverser les ajours de cette structure et, de ce fait, la renforcer. It is possible to stiffen the assembly in the final form by incorporating metal reinforcements which will cross the openings of this structure and, therefore, strengthen it.
On comprend qu'il soit facile d'appliquer du béton dans le volume de la structure, les lattis maintenant en place le béton le temps du séchage. We understand that it is easy to apply concrete in the volume of the structure, the laths holding the concrete in place during drying.
Dans un autre mode de mise en oeuvre, on coule par injection au moyen d'un système de pompage du béton à travers l'un des lattis jusqu'à refus du béton à travers ce lattis. In another embodiment, the injection is poured by means of a concrete pumping system through one of the laths until the concrete is rejected through this lath.
Dans un, autre mode de mise en oeuvre, encore de l'invention, on projette du mortier ou du plâtre sur chaque face de lattis, créant ainsi une cloison évidée en son centre. In another embodiment, still of the invention, mortar or plaster is sprayed on each face of the lath, thus creating a partition hollowed out at its center.
La description qui va suivre, faite en référence aux dessins annexés, donne uniquement, à titre d'exemples, quelques modes de mise en oeuvre. The description which follows, given with reference to the appended drawings, gives only, by way of examples, some modes of implementation.

In these drawings - Figure 1 shows a front view of part of a corrugated lath panel object of the invention, - Figure 2 shows a cross section through the ribs of the lath of Figure 1, - Figure 3 shows schematically a longitudinal section of the corrugated lath in the direction of the ribs of this lath, - Figure 4 shows, in horizontal section, the assembly of the two metal lath panels, - Figure 5 shows, in horizontal section, the assembly of the two lath panels in convex shape, - - Figure 6 shows, in horizontal section, the assembly of the two lath panels in concave shape, - Figure 7 shows a horizontal section of a structure complete just before pouring the concrete in its volume, - Figure 8 shows, schematically, the construction of a vertical wall, made of lightweight concrete, positioned on a concrete support, from a structure such as that illustrated in figure 7, - figure 9 shows the reco uvrement of metal lath plates between them, - Figure 10 shows a horizontal section of a complete structure in another mounting mode but whose construction characteristics are comparable to Figure 7.
En se référant, tout d'abord, aux figures 1, 2 et 3, on a montré la structure d'un panneau de lattis métallique nervuré, étiré, ajouré et ondulé, adapté à la mise en oeuvre du procédé. Referring, first of all, to FIGS. 1, 2 and 3, the structure of a ribbed, stretched, perforated and corrugated metal lath panel is shown, suitable for the implementation of the method.
Ce matériau, du commerce, trouve ses applications dans les techniques du bâtiment. This commercial material finds its applications in building techniques.
Avantageusement, le panneau de lattis métallique en question sera constitué en acier galvanisé, par exemple en tôle de 2/1ou à 3/10 de millimètres, perforée puis étirée formant ainsi des losanges (référencées A figure 1) de diagonales de 10 millimètres pour la diagonale la plus courte et 20 millimètres pour la diagonale la plus longue. Advantageously, the metal lath panel in question will be made of galvanized steel, for example of sheet metal of 2/1 or 3/10 of millimeters, perforated and then drawn, thus forming diamonds (referenced in FIG. 1) with diagonals of 10 millimeters for the shortest diagonal and 20 millimeters for the longest diagonal.
Des nervures longitudinales, plièes dans le sens de la longueur, créant un profil en V, feront office de raidisseurs. Ces nervures seront espacèes de 10 centimètres (référencées C figure 1). Longitudinal ribs, bent lengthwise, creating a V-shaped profile, will act as stiffeners. These ribs will be spaced 10 centimeters apart (referenced C in figure 1).
A partir d'un tel panneau, initialement plan, on forme un panneau ondulé tel qu'il apparait plus clairement sur les figures 1, 2 et 3. From such a panel, initially planar, a corrugated panel is formed as it appears more clearly in FIGS. 1, 2 and 3.
En pliant par emboutissage (référencé B figure 1), le panneau régulièrement suivant un espacement constant (référencé F figures 1 et 3), on crée des ondes pour former des sommets (référencés S figure 3). By bending by stamping (referenced B in figure 1), the panel regularly at a constant spacing (referenced in F 1 and 3), waves are created to form vertices (referenced in S 3).
La hauteur (référencée H figures 2 et 3) des ondes (référencées S figure 3) peut être, dans l'exemple envisagé, de 5 centimètres, la longueur peut-être de 7 centimètres (référencée L figure 3). The height (referenced H in FIGS. 2 and 3) of the waves (referenced S in FIG. 3) can be, in the example envisaged, of 5 centimeters, the length perhaps 7 centimeters (referenced L in FIG. 3).
Bien évidemment, les dimensions ci-dessus indiquées, ne le sont qu'à titre d'exemple et peuvent être modifiées considérablement, selon la nature de l'ouvrage que l'on veut réaliser. Obviously, the dimensions indicated above are only by way of example and can be modified considerably, depending on the nature of the work that one wishes to achieve.
On fera, maintenant, référence à la figure 7 dans laquelle on a montré que l'on pouvait renforcer une telle structure ajourée, ondulée, au moyen d'armatures de renforcement telles que 3 introduites dans les ajours du lattis parallèlement à la direction x, x' et 4 en position verticale dans l'onde du lattis. Reference will now be made to FIG. 7 in which it has been shown that such an openwork, wavy structure could be reinforced by means of reinforcements such as 3 introduced into the openings of the lattice parallel to the direction x, x 'and 4 in vertical position in the lath wave.
De façon plus précise, chaque face de panneaux de lattis métalliques se recouvre en leurs nervures d'une façon identique pour les lattis plans que les lattis ondulés entre eux (référencée 11 et 12 figure 9). Ils sont agrafés entre eux (6). More precisely, each face of metal lath panels is covered in their ribs in an identical manner for flat laths as the laths corrugated with one another (referenced 11 and 12 in FIG. 9). They are stapled together (6).
Les ondes des lattis ondulés ayant un espacement constant (F), elles
se retrouvent systèmatiquement en bonne position, lors de leur
recouvrement, faisant coincider le maillage, ce qui permet l'incorporation des armatures de renforcement horizontales (3); celle-ci bloquant les armatures de renforcement verticales (4) positionnées en fond de l'onde du lattis métallique.The waves of the wavy laths having a constant spacing (F), they
are systematically in a good position when they are
overlap, making the mesh coincide, which allows the incorporation of the horizontal reinforcements (3); this blocking the vertical reinforcement frames (4) positioned at the bottom of the wave of the metal lath.
Dans le mode de réalisation, illustré à la figure 7, on vient appliquer sur les deux lattis, agrafés entre eux (6), formant la structure, une couche de mortier ou de plâtre (5) en prenant soin d'appliquer une couche de remplissage du volume de l'onde (7). Le tout constituant ainsi une cloison. In the embodiment, illustrated in FIG. 7, a layer of mortar or plaster (5) is applied to the two battens, stapled together (6), forming the structure, taking care to apply a layer of filling the volume of the wave (7). The whole thus constituting a partition.
Pour la construction d'un mur plein en béton allégé (figure 8), il suffit, à partir d'une installation schématisée (9), d'injecter le béton à l'intérieur du volume (8) de la structure positionnée sur une embase béton (10), directement, à travers le lattis jusqu'à refus du béton. On prendra, également, soin de remplir le volume de l'onde (7). For the construction of a full wall of lightened concrete (Figure 8), it suffices, from a schematic installation (9), to inject the concrete inside the volume (8) of the structure positioned on a concrete base (10), directly, through the lath until concrete refuses. We will also take care to fill the volume of the wave (7).
Il est ainsi possible de constituer, à partir de l'invention, toutes épaisseurs de parois voulues, suivant l'importance de l'onde. It is thus possible to constitute, from the invention, any desired wall thickness, depending on the importance of the wave.
On fera, maintenant, référence à la figure 10 dans laquelle on a illustré une autre application de l'invention. Reference will now be made to FIG. 10 in which another application of the invention has been illustrated.
Dans cette application, on utilise deux panneaux de lattis métalliques, ondulés, suivant l'invention. On positionne ces deux panneaux face à face en raccordant, par agrafage, les ondes entre elles (6), les armatures de renforcement (3et 4) pouvant être incorporées de la même façon que dans la figure 7. In this application, two corrugated metal lath panels are used according to the invention. These two panels are positioned face to face by connecting, by stapling, the waves between them (6), the reinforcing reinforcements (3 and 4) being able to be incorporated in the same way as in FIG. 7.
Parmi les nombreux avantages de l'invention, on citera la souplesse et la facilité d'emploi du procèdé, son application à tous types de construction et la possibilité d'employer le type de béton approprié (lourd, léger, isolant, phonique ou thermique). Among the many advantages of the invention, mention will be made of the flexibility and ease of use of the process, its application to all types of construction and the possibility of using the appropriate type of concrete (heavy, light, insulating, sound or thermal). ).
