Abstract
Description
La présente invention a pour objet de présenter un nouveau dispositifThe present invention aims to present a new device
d'accrochage au parement des armatures métalliques en treillis soudé, pour la réalisation des murs de soutènement à partir de la technique de renforcement de sol ou pour la réalisation d'un revêtement minéral constitué de parements en treillis soudé, fixés par fastening to the siding of the welded wire reinforcements, for the realization of the retaining walls from the soil reinforcement technique or for the realization of a mineral coating consisting of welded mesh facings, fixed by
scellement sur une paroi existante.sealing on an existing wall.
Nous ne traiterons pas les modalités propres à la réalisation de ce type d'ouvrage, exposées dans d'autres textes ou brevets. We will not deal with the specific modalities for the realization of this type of work, exposed in other texts or patents.
L'armature du renforcement est constituée soit d'une barre isolée en acier, soit d'un treillis soudé métallique dont au moins une des barres longitudinales dans la 10 direction perpendiculaire au parement est accrochée audit parement. The reinforcing reinforcement consists of either an insulated steel bar or a welded wire mesh with at least one of the longitudinal bars in the direction perpendicular to the facing being attached to said facing.
Les figures 1-1 à 6 présentent le contexte ainsi que l'objet et la nouveauté de la présente invention. Figures 1-1 to 6 show the context as well as the object and novelty of the present invention.
La figure 1-1 montre la configuration de soutènement visée par l'invention. Il s'agit d'un remblai renforcé (1) par des armatures en treillis soudé (2), dite par la suite: RENFORT . Le parement du massif (3) est en béton, en bois, en panneau de treillis soudé ou d'autres matériaux de construction. Figure 1-1 shows the support configuration of the invention. It is a reinforced embankment (1) by welded mesh reinforcements (2), hereinafter called: REINFORCEMENT. The facing of the solid (3) is concrete, wood, welded mesh panel or other building materials.
La figure 1-2 présente un autre créneau de l'invention. Il s'agit d'une paroi en béton, en terre ou en maçonnerie existante (3-a), revêtue de pierres montées à sec et logées entre ladite paroi et un parement (3) constitué de panneaux en treillis soudé (10). Figure 1-2 shows another slot of the invention. It is an existing concrete, earth or masonry wall (3-a), covered with dry-mounted stones and housed between said wall and a facing (3) consisting of welded mesh panels (10).
Ce dernier étant fixé sur la paroi par scellement des éléments d'accroche, dits renforts (2-a). The latter being fixed on the wall by sealing of the attachment elements, said reinforcements (2-a).
Les figures 2-1 à 2-3 présentent la forme générale d'un renfort en treillis soudé (2). Le renfort se trouve toujours à l'horizontale dans le plan XY. Figures 2-1 to 2-3 show the general shape of a welded mesh reinforcement (2). The reinforcement is always horizontal in the XY plane.
A son extrémité, coté parement, le renfort comporte une boucle ouverte (4) , obtenue par cintrage à environ 180 des barres longitudinales (5) du renfort, autour d'un axe (6). L'axe du cintrage (6) peut être suivant l'axe Y ou Z. La Figure 2-1 montre le pliage autour de Y. L'objectif étant d'accrocher le renfort (2) au parement moyennant une barre (8) ou un tube (9) dite barre de liaison , inclue dans le parement (3) et parallèle à l'axe du cintrage (6). La barre (8) correspond à une des barres du parement en treillis soudé (10), Figure 2-2 et le tube (9) est intégré dans un parement en béton, Figure 2-3. At its end, side facing, the reinforcement comprises an open loop (4), obtained by bending about 180 longitudinal bars (5) of the reinforcement, about an axis (6). The axis of the bending (6) can be along the Y or Z axis. Figure 2-1 shows the folding around Y. The objective is to hang the reinforcement (2) to the facing with a bar (8) or a tube (9) called connecting bar, included in the facing (3) and parallel to the axis of the bending (6). The bar (8) corresponds to one of the bars of the welded mesh facing (10), Figure 2-2 and the tube (9) is integrated in a concrete facing, Figure 2-3.
Précisons qu'au cas où le parement (3) est un constitué d'un treillis soudé (10), la barre du treillis soudé (8) sur laquelle on accroche la boucle (4) se trouve toujours coté extérieur du parement, que la barre soit horizontale ou verticale. It should be noted that in the case where the facing (3) is made of a welded mesh (10), the welded mesh bar (8) on which the loop (4) is fastened is always on the outside of the facing, which the bar either horizontal or vertical.
-2- 2869051 Par exemple, dans la configuration montrée sur la figure 2-2, les boucles (4) du renforts (2) sont dans un plan vertical en position de pose, elles s'accrochent donc sur une barre horizontale du treillis (8), cette barre horizontale se trouvant à l'extérieur du parement. For example, in the configuration shown in Figure 2-2, the loops (4) of the reinforcements (2) are in a vertical plane in the laying position, so they hang on a horizontal bar of the lattice ( 8), this horizontal bar being on the outside of the facing.
Ainsi, ladite barre de liaison (8) est horizontale si l'axe du cintrage (6) est horizontal, c'est à dire la boucle verticale: configuration A. La barre de liaison (8) est verticale si l'axe du cintrage (6) est vertical, c'est à dire la boucle horizontale: configuration B. Dans la suite du texte, nous aborderons la configuration A; la configuration 10 B en sera facilement déductible. Thus, said connecting bar (8) is horizontal if the bending axis (6) is horizontal, ie the vertical loop: configuration A. The connecting bar (8) is vertical if the bending axis (6) is vertical, ie the horizontal loop: configuration B. In the rest of the text, we will discuss the configuration A; the configuration 10 B will be easily deductible.
Lors du montage du mur, la barre de liaison (8) se trouvant au fond de la boucle ouverte, l'accrochage est ainsi obtenu. When mounting the wall, the connecting bar (8) located at the bottom of the open loop, the attachment is thus obtained.
Ce dispositif d'accrochage comporte un inconvénient technique et donc économique. Le renfort subi de la traction due aux poussées des pierres (cas de la figure 1-2) ou due aux efforts d'ancrage dans le massif renforcé (cas de la figure 1-1). Des tests d'arrachement montrent que la résistance de la boucle ouverte n'est que de l'ordre de 30 à 40% de la résistance d'une boucle fermée. En effet, suite à ces efforts de traction dans le renfort, la boucle a tendance à s'ouvrir autour de l'axe du cintrage (6), voir la Figure 3. D'autre part, pour des raisons de montage sur chantier, il n'est pas toujours possible de préfabriquer le renfort avec une boucle fermée, en usine. C'est le cas, par exemple, lorsque la barre d'accrochage (8) fait partie intégrante du treillis soudé du parement. This attachment device has a technical disadvantage and therefore economical. The reinforcement undergone by the pulling of stones (case of Figure 1-2) or due to the anchoring efforts in the reinforced solid (case of Figure 1-1). Pullout tests show that the resistance of the open loop is only in the order of 30 to 40% of the resistance of a closed loop. Indeed, following these tensile forces in the reinforcement, the loop tends to open around the axis of the bending (6), see Figure 3. On the other hand, for reasons of assembly on site, it is not always possible to prefabricate the reinforcement with a closed loop, at the factory. This is the case, for example, when the attachment bar (8) is an integral part of the welded mesh of the facing.
La figure 4 expose une première solution proposée par la présente invention. La démonstration est illustrée pour une des barres longitudinales (5) des renforts. La même démarche est appliquée à toutes les barres longitudinales (5) devant être accrochées au parement. Figure 4 shows a first solution proposed by the present invention. The demonstration is illustrated for one of the longitudinal bars (5) reinforcements. The same approach is applied to all the longitudinal bars (5) to be hung on the facing.
Il s'agit d'empêcher l'ouverture de la boucle ouverte, grâce à un élément linéaire et creux type profilé à section préférentielle circulaire en forme tube (I l), ovoïde (1 1-1) ou polygone (1 1-2), en acier ou d'autres matériaux type composite, qui enveloppe 3o à la fois la barre longitudinale (5) et son retour (7) obtenu par l'opération de cintrage. This is to prevent the opening of the open loop, thanks to a linear element and hollow type profiled circular preferential section tube (I l), ovoid (1-1 1) or polygon (1 1-2 ), steel or other composite type material, which wraps 3o both the longitudinal bar (5) and its return (7) obtained by the bending operation.
Afin d'un meilleur blocage des barres (5) et (7), un second élément linéaire, plein ou creux, (1 Lb), sera inséré à l'intérieur de l'élément creux (Il) entre les deux barres (5) et (7), les mettant en butée contre la paroi intérieure de l'élément (1 1). In order to better block the bars (5) and (7), a second linear element, solid or hollow, (1 Lb), will be inserted inside the hollow element (II) between the two bars (5). ) and (7), abutting them against the inner wall of the element (1 1).
-3- 2869051 La figure 5 montre comment on procède à l'accrochage des renforts au parement. La démonstration est faite pour un élément constitutif du parement en treillis soudé (I 0) ; le principe s'applique à d'autres types de parement avec des adaptations nécessaires, au cas échéant. -3- 2869051 Figure 5 shows how we attach the reinforcements to the facing. The demonstration is made for a constituent element of welded mesh facing (I 0); the principle applies to other types of siding with necessary adaptations, if necessary.
/ ETAPE 1: On glisse dans le renfort (2), du coté de la boucle (4), un tube (Il) de diamètre intérieur (13) légèrement supérieur au diamètre extérieur de la boucle. Ce tube a une épaisseur plutôt faible, de l'ordre de quelques millimètres s'il est en acier. La longueur du tube (14) est inférieure à la distance (16) entre la première barre transversale (15) Ill du renfort et l'extrémité de la partie pliée (7) de la barre longitudinale (5). Ce tube reste en attente des opérations suivantes. Les éléments (11-1) ou (11-2). peuvent être indifféremment employés au lieu de l'élément (11). / STEP 1: In the reinforcement (2), on the side of the loop (4), a tube (II) of inner diameter (13) is slightly greater than the outer diameter of the loop. This tube has a rather low thickness, of the order of a few millimeters if it is steel. The length of the tube (14) is less than the distance (16) between the first transverse bar (15) of the reinforcement and the end of the folded portion (7) of the longitudinal bar (5). This tube remains waiting for the following operations. Elements (11-1) or (11-2). may be used interchangeably instead of the element (11).
/ ETAPE 2: On positionne l'élément constitutif du parement (10). On 15 positionne ensuite le renfort (2) muni du tube (11), face au parement (10). / STEP 2: The component of the facing (10) is positioned. The reinforcement (2) is then positioned with the tube (11) facing the facing (10).
/ ETAPE 3: On fait traverser le renfort muni du tube dans les mailles (17) de l'élément constitutif du parement (10), le tube ne traversant pas la maille du parement. / STEP 3: The reinforcement provided with the tube is passed through the mesh (17) of the component of the facing (10), the tube not passing through the mesh of the facing.
/ ETAPE 4: On remonte le renfort de telle sorte que la boucle se trouve face de la barre de liaison (8) de l'élément constitutif du parement. / STEP 4: Raise the reinforcement so that the loop is facing the connecting bar (8) of the component of the facing.
/ ETAPE 5: On retire le renfort vers le remblai pour créer le contact entre le renfort et le parement en mettant en butée le fond de la boucle ouverte contre la barre de liaison (8). / STEP 5: Remove the reinforcement towards the backfill to create the contact between the reinforcement and the facing by putting the end of the open loop against the connecting bar (8).
/ ETAPE 6: On déplace le tube, préalablement positionné dans le renfort, vers le parement de sorte qu'il enveloppe la boucle en contenant aussi bien la barre longitudinale (5) que son retour (7). / STEP 6: The tube, previously positioned in the reinforcement, is moved towards the facing so that it envelops the loop by containing both the longitudinal bar (5) and its return (7).
/ ETAPE 7: On insère, éventuellement, l'élément linéaire (1 Lb) entre les deux barres (5) et (7). / STEP 7: Optionally insert the linear element (1 Lb) between the two bars (5) and (7).
3o L'opération d'accrochage est ainsi achevée. On peut alors procéder au remblaiement sur le renfort et continuer les opérations en réitérant les différentes étapes ci-dessus. 3o The snap operation is thus completed. We can then backfill the reinforcement and continue operations by repeating the steps above.
Dans le cas du revêtement d'une paroi existante par des panneaux en treillis et pierres, figure 1-2, le renfort 2-a, étant scellé dans la paroi, reste figé et c'est le treillis du -4- 2869051 parement (10) qui fait l'objet des déplacements des étapes 2 à 5 indiquées dans la figure 5. In the case of the coating of an existing wall with lattice and stone panels, Figure 1-2, the reinforcement 2-a, being sealed in the wall, remains fixed and it is the lattice of the facing. 10) which is the subject of the displacements of steps 2 to 5 indicated in FIG.
L'avantage apporté par la mise en place de l'élément (11), (1 l -1) ou (11-2) dans les conditions décrites ci-dessus consiste à empêcher l'ouverture de la boucle d'accrochage suite aux efforts d'ancrage sur le renfort en fonctionnement. Ce dispositif a donc comme conséquence de supprimer la zone de faible résistance dans la zone de l'accrochage au parement. The advantage provided by the introduction of the element (11), (1 l -1) or (11-2) under the conditions described above is to prevent the opening of the snap loop following the anchoring efforts on the reinforcement in operation. This device therefore has the effect of eliminating the zone of low resistance in the zone of clinging to the cladding.
Comme le montre la figure 6, une seconde solution consiste à remplacer le tube (l 1) précédemment décrit par un corps plein d'une forme préférentielle io parallélépipédique (18) ou cylindrique (18-b) ou un profilé (18-a), comportant au moins deux trous traversant et parallèles (19), de diamètre (20) légèrement supérieur au diamètre (21) des barres (5) et (7). L'entraxe (22) des trous correspond sensiblement à l'entraxe (12) entre la barre longitudinale (5) et son retour (7). As shown in FIG. 6, a second solution consists in replacing the tube (11) previously described by a solid body of a preferred parallelepipedic (18) or cylindrical (18-b) shape or a profile (18-a). , having at least two through-holes and parallel (19), of diameter (20) slightly greater than the diameter (21) of the bars (5) and (7). The spacing (22) of the holes substantially corresponds to the spacing (12) between the longitudinal bar (5) and its return (7).
Suivant ce dispositif, la barre longitudinale (5) du renfort (2) et le retour plié (7) de cette même barre, rentrent dans les deux trous (19). L'élément (18) , (18-a) ou (18-b), reliant les deux barres, empêche la boucle de s'ouvrir sous effet desdits efforts de traction. De même qu'envisagé pour les tubes (11), la longueur (23) de l'élément (18), (18-a) ou (18-b), est inférieure à la distance (16), définie précédemment dans la Figure 5. According to this device, the longitudinal bar (5) of the reinforcement (2) and the folded return (7) of this same bar, fit into the two holes (19). The element (18), (18-a) or (18-b), connecting the two bars, prevents the buckle from opening under the effect of said traction forces. As is envisaged for the tubes (11), the length (23) of the element (18), (18-a) or (18-b) is smaller than the distance (16) defined previously in FIG. Figure 5
