Abstract

A reinforcement includes two parallel walls formed with braces arranged along two orthogonal directions, the walls being spaced apart by tie rods. The structure further includes on at least one of its formwork surfaces a permeable structure for retaining aggregate and allowing excess water of cast concrete to escape. According to the invention, at least one of the parallel walls includes two mutually independent grates, one the grates being associated with the other wall by a first set of tie rods, and the other of the grates being associated with the other wall by a second set of tie rods, independent of the first set. When the grates are displaced in opposite directions along an axis parallel to the plane of the grates, the spacing between the walls is modified.

Description

L'invention se rapporte à une armature pour paroi en béton.The invention relates to a reinforcement for a concrete wall.

Elle se rapporte également à l'utilisation de cette armature dans un coffrage perdu.It also relates to the use of this frame in a lost formwork.

La réalisation de paroi en béton coulé nécessite, avant la coulée du béton de délimiter le volume dans lequel sera coulé le matériau à l'aide de parois coffrantes.The production of a poured concrete wall requires, before pouring the concrete, to delimit the volume into which the material will be poured using formwork walls.

Pour renforcer la résistance des murs, il est connu d'y loger des fers à béton qui, assemblés entre eux, constituent une armature.To strengthen the resistance of the walls, it is known to house concrete irons which, assembled together, constitute a frame.

La technique consiste généralement à fixer ces armatures sur place voire éventuellement, hors site mais se pose le problème du transport qui grève fortement le prix car ces armatures sont alors volumineuses.The technique generally consists in fixing these reinforcements on site or even possibly, off site but there is the problem of transport which strongly increases the price because these reinforcements are then bulky.

Si la technique de coulage du béton à l'aide de banches de coffrage est largement utilisée, il y a quelques années la technique du coffrage filtrant perdu est apparue sur le marché (cf, WO 97/31165 A).If the technique of pouring concrete using formwork formwork is widely used, a few years ago the technique of lost filtering formwork appeared on the market (cf., WO 97/31165 A).

Cette technique a l'avantage de permettre l'évacuation de l'eau excédentaire du béton.This technique has the advantage of allowing the evacuation of excess water from the concrete.

En effet, avec une paroi filtrante, le béton contenu dans le coffrage ne se comporte plus comme un fluide créant une pression hydrostatique, laquelle est proportionnelle à la hauteur de béton coulé au dessus du niveau considéré et de ce fait, les forces développées par ce béton sont beaucoup plus faibles.Indeed, with a filtering wall, the concrete contained in the formwork no longer behaves like a fluid creating a hydrostatic pressure, which is proportional to the height of concrete poured above the level considered and therefore the forces developed by this concrete are much weaker.

Cela permet notamment d'utiliser des coffrages légers qui peuvent être mis en place sans nécessiter de recourir à un engin de levage.This allows in particular the use of light formwork which can be put in place without requiring the use of a lifting device.

Dans les réalisations connues à ce jour, ce coffrage filtrant se présente sous la forme de deux parois :

  • obtenues par assemblage de panneaux perméables retenant les agrégats et laissant s'échapper l'eau, les panneaux étant alors en métal déployé et,
  • maintenues à l'écartement requis par la présence d'entretoises qui, lorsque le coffrage est en place, s'étendent dans des plans perpendiculaires aux faces coffrantes.
In the embodiments known to date, this filtering formwork is in the form of two walls:
  • obtained by assembling permeable panels retaining the aggregates and letting the water escape, the panels then being made of expanded metal and,
  • maintained at the spacing required by the presence of spacers which, when the formwork is in place, extend in planes perpendicular to the formwork faces.

Pour permettre le transport de ces coffrages perdus, les entretoises sont reliées aux parois coffrantes par des articulations de sorte que, lorsque l'une des parois coffrante est déplacée en translation, les entretoises se rabattent toutes d'un même côté.To allow the transport of these lost forms, the spacers are connected to the formwork walls by joints so that, when one of the formwork walls is moved in translation, the spacers are all folded down on the same side.

En réalité, les entretoises sont associées à des raidisseurs sur lesquels sont fixés les panneaux en métal déployé.In reality, the spacers are associated with stiffeners on which the expanded metal panels are fixed.

Selon la forme des entretoises, il est possible de faire participer celles-ci à la résistance de la paroi coulée notamment en créant un effet de frette mais, essentiellement, dans un plan perpendiculaire au plan dans lequel s'étend cette entretoise.Depending on the shape of the spacers, it is possible to make them participate in the resistance of the poured wall in particular by creating a hoop effect but, essentially, in a plane perpendicular to the plane in which this spacer extends.

L'invention a pour objectif d'accroître la résistance des murs.The invention aims to increase the resistance of the walls.

Elle a également pour but d'améliorer les performances des coffrages perdus du type précité.It also aims to improve the performance of lost formwork of the aforementioned type.

A cet effet, l'invention a pour objet une armature pour paroi en béton comprenant une structure porteuse constituée de deux parois parallèles, formées chacune de ferrures disposées selon deux directions orthogonales et ces parois sont maintenues à l'écartement requis par des entretoises, cette armature étant caractérisée en ce que :

  • l'une des deux parois parallèles est constituée de deux grilles indépendantes l'une de l'autre,
  • l'une des deux grilles indépendantes est associée à l'autre paroi par un premier ensemble d'entretoises et
  • l'autre grille de cette paroi est associée également à l'autre paroi par un deuxième ensemble d'entretoises indépendantes de celles du premier ensemble de sorte qu'en déplaçant les grilles en sens opposé et selon un axe parallèle au plan des grilles, on modifie l'écartement des parois.
To this end, the subject of the invention is a reinforcement for a concrete wall comprising a supporting structure consisting of two parallel walls, each formed of fittings arranged in two orthogonal directions and these walls are maintained at the spacing required by spacers, this armature being characterized in that:
  • one of the two parallel walls consists of two grids independent of each other,
  • one of the two independent grids is associated with the other wall by a first set of spacers and
  • the other grid of this wall is also associated with the other wall by a second set of spacers independent of those of the first set so that by moving the grids in opposite directions and along an axis parallel to the plane of the grids, changes the spacing of the walls.

Elle a également pour objet l'utilisation de cette armature.It also relates to the use of this frame.

L'invention sera bien comprise à l'aide de la description ci-après faite à titre d'exemple non limitatif en regard du dessin ci-annexé qui représente schématiquement :

  • figures 1 et 2 : vues d'une structure en position utilisable,
  • figure 3 : une vue de côté d'un coffrage montrant la cinétique de mise en position,
  • figure 4 : une vue de dessus d'un coffrage,
  • figures 5 et 6 : des détails de réalisation,
  • figure 7 : une vue en perspective montrant la cinétique
The invention will be clearly understood with the aid of the description below given by way of nonlimiting example with regard to the appended drawing which schematically represents:
  • Figures 1 and 2: views of a structure in a usable position,
  • FIG. 3: a side view of a formwork showing the kinetics of positioning,
  • Figure 4: a top view of a formwork,
  • Figures 5 and 6: details of construction,
  • Figure 7: a perspective view showing the kinetics

En se reportant au dessin, on voit une armature 1 de renfort d'une paroi en béton.Referring to the drawing, we see a reinforcement 1 for reinforcing a concrete wall.

On y voit également un coffrage perdu filtrant.We also see a lost filtering formwork.

Ce coffrage perdu peut être utilisé pour obtenir des parois verticales ou horizontales.This lost formwork can be used to obtain vertical or horizontal walls.

Classiquement, ce coffrage comprend une structure porteuse 1 comprenant deux parois 2, 3 parallèles formées chacune de ferrures disposées selon deux directions orthogonales et ces parois 2, 3 sont maintenues à l'écartement requis par des entretoises 4, 5.Conventionally, this formwork comprises a support structure 1 comprising two parallel walls 2, 3 each formed of fittings arranged in two orthogonal directions and these walls 2, 3 are maintained at the spacing required by spacers 4, 5.

Dans le cas de l'utilisation de cette armature, en tant que structure de coffrage perdu à paroi filtrante 100, cette armature présente en outre sur au moins l'une de ses faces coffrantes une structure perméable retenant les agrégats et laissant s'échapper l'eau excédentaire du béton coulé.In the case of the use of this frame, as a lost formwork structure with a filtering wall 100, this frame also has, on at least one of its formwork faces, a permeable structure retaining the aggregates and letting escape. excess water from poured concrete.

Selon une autre variante, au moins l'une des parois coffrantes est imperméable.According to another variant, at least one of the formwork walls is impermeable.

Selon une caractéristique de l'invention :

  • l'une (2) des deux parois 2, 3 parallèles est constituée de deux grilles indépendantes l'une de l'autre ,
  • l'une (2A) des deux grilles 2A, 2B indépendantes est associée à l'autre paroi 3 par un premier ensemble d'entretoises 4 et
  • l'autre grille 2B de cette paroi est associée également à l'autre paroi 3 par un deuxième ensemble d'entretoises 5 indépendantes de celles (4) du premier ensemble de sorte qu'en déplaçant les grilles en sens opposé et selon un axe parallèle au plan des grilles, on modifie l'écartement des parois.
According to a characteristic of the invention:
  • one (2) of the two parallel walls 2, 3 consists of two grids independent of each other,
  • one (2A) of the two independent grids 2A, 2B is associated with the other wall 3 by a first set of spacers 4 and
  • the other grid 2B of this wall is also associated with the other wall 3 by a second set of spacers 5 independent of those (4) of the first set so that by moving the grids in opposite directions and along an axis parallel to the plane of the grids, the spacing of the walls is modified.

Avantageusement :

  • les entretoises 4 du premier ensemble d'entretoises s'étendent dans des premiers plans parallèles et inclinés par rapport à un plan perpendiculaires aux deux parois parallèles,
  • les entretoises 5 du second ensemble d'entretoises s'étendent également dans des seconds plans parallèles et inclinés par rapport à un plan perpendiculaire aux deux parois parallèles,
  • lesquels premier et second plans sont, entre eux, sécants et alternés.
Advantageously:
  • the spacers 4 of the first set of spacers extend in first parallel planes and inclined with respect to a plane perpendicular to the two parallel walls,
  • the spacers 5 of the second set of spacers also extend in second parallel planes and inclined relative to a plane perpendicular to the two parallel walls,
  • which foreground and second planes are, intersecting and alternating.

Ce coffrage est donc repliable malgré l'orientation des entretoises qui constituent, lorsque la structure porteuse est en position dépliée, une structure triangulée.This formwork is therefore foldable despite the orientation of the spacers which constitute, when the support structure is in the unfolded position, a triangulated structure.

Les entretoises 4, 5 sont, par exemple, obtenues par pliage d'un fil en zigzag qui s'accroche derrière certaine des barres de la grille.The spacers 4, 5 are, for example, obtained by bending a zigzag wire which hangs behind some of the bars of the grid.

Les points d'accrochage des fils pliés en zig zag du premier ensemble d'entretoises sont, pour une paroi, matérialisés par les barreaux ou ferrures de numéros pairs tandis que les points d'accrochage des fils pliés en zig zag du second ensemble d'entretoises sont, pour la même paroi, matérialisés par les barreaux de numéros impairs.The attachment points of the zig zag folded wires of the first set of spacers are, for a wall, materialized by bars or fittings of even numbers while the attachment points of the zig zag wires of the second set of spacers are, for the same wall, materialized by the bars of odd numbers.

Ainsi, vus de dessus, les fils en zig zag délimitent des losanges et demi-losanges.Thus, seen from above, the zig zag threads define diamonds and half-diamonds.

Les deux grilles 2A, 2B sont maintenues entre elles à une distance prédéterminée par des moyens 10 d'association, lesquels moyens d'association comprennent un moyen de guidage en translation des deux grilles dans un plan parallèles au deux grilles.The two grids 2A, 2B are held together at a predetermined distance by means of association, which association means comprise means for guiding in translation the two grids in a plane parallel to the two grids.

Ces moyens 10 d'association sont, par exemple, constitués par un pièce de retenue ou épingle élastique formant autour du barreau deux crochets 11, 12 ou boucles réunis par une lame 13 élastique qui, par réaction sur une barre transversale, maintient les barres et barreaux et/ou entretoises.These association means 10 are, for example, constituted by a retaining piece or elastic pin forming around the bar two hooks 11, 12 or loops joined by an elastic blade 13 which, by reaction on a transverse bar, maintains the bars and bars and / or spacers.

Les entretoises sont ainsi réalisées par des épingles en acier à ressort.The spacers are thus produced by spring steel pins.

Les ressorts ont une forme étudiée de façon à développer les forces d'action et de réaction sur chacune des armatures horizontale et verticale.The springs have a shape studied in order to develop the forces of action and reaction on each of the horizontal and vertical reinforcements.

Au contact des barres, ces efforts développent une force de frottement proportionnelle à la raideur du ressort-clips.In contact with the bars, these forces develop a friction force proportional to the stiffness of the clip spring.

Il est à noter que cette force de frottement est considérablement augmentée dans le cas d'utilisation de fer « Tor » grâce à la présence des aspérités de ces derniers.It should be noted that this friction force is considerably increased in the case of using “Tor” iron thanks to the presence of the roughness of the latter.

La figure 6 représente un exemple de réalisation de clips de blocage pour armatures horizontale et verticale/crochet.FIG. 6 represents an exemplary embodiment of locking clips for horizontal and vertical armatures / hook.

La figure 5 représente un exemple de réalisation de clips de blocage pour armature verticale et horizontale.FIG. 5 represents an exemplary embodiment of locking clips for vertical and horizontal reinforcement.
