Abstract
Description
L'invention concerne une planche de coffrage montée à demeure sur un ouvrage en béton. The invention relates to a formwork board permanently mounted on a concrete structure.
Des panneaux et/ou des planches de coffrage sont utilisés pour la construction des ouvrages en béton. Indépendamment des coffrages en bois orientés vers le sous-sol d'une fouille les coffrages en bois ou en tôle d'acier sont récupérés. Le coffrage est coûteux et exige du temps. Panels and / or formwork boards are used for the construction of concrete structures. Regardless of the wooden formwork oriented towards the basement of a dig, the wooden or sheet steel formwork is recovered. Formwork is expensive and time consuming.
Lorsque des mesures sont prévues pour calorifuger les surfaces non enterrées d'un ouvrage en béton, des éléments de constructions appropriés sont de nouveau appliqués après le décoffrage sur les parties correspondantes de l'ouvrage.When measures are planned to insulate the non-buried surfaces of a concrete structure, suitable construction elements are again applied after formwork removal to the corresponding parts of the structure.
Partant de l'état de la technique qui vient d'être décrit,
I'invention se propose de créer un coffrage pouvant être laissé à demeure sur l'ouvrage d'une part et qui, le cas échéant, rerrplit alors également des fonctions.Starting from the state of the art which has just been described,
The invention proposes to create a formwork which can be left permanently on the structure on the one hand and which, if necessary, then also fulfills functions.
L'invention pernet de réaliser cet objet par une planche de coffrage en béton présentant une résistance et une ténacité accrues obtenues par des adjonctions appropriées et qui comprend d'un côté au groins des saillies s'engageant positivement dans le béton se trouvant derrière La résistance et la ténacité plus. grandes qui sont nécessaires pour l'utili: sation prévue sont obtenues par du béton de ciment et de fibres ou par un béton mélangé avec un composant élastique tel que par exenple un polymère approprié. La planche en béton résiste alors également aux intenpéries. The invention makes it possible to achieve this object by a concrete formwork board having increased strength and toughness obtained by appropriate additions and which comprises on one side at the edges of the projections positively engaging in the concrete lying behind The resistance and toughness more. large that are necessary for the intended use are obtained by cement and fiber concrete or by concrete mixed with an elastic component such as for example a suitable polymer. The concrete plank then also resists bad weather.
La nouvelle planche de coffrage est utilisée, le cas échéant, en étant incorporée dans des coffrages standard, et elle est laissée sur place après le décoffrage. Les saillies de la planche noyées dans le béton assurent une excellente liaison avec l'ouvrage. The new formwork board is used, if necessary, by being incorporated into standard formwork, and is left in place after formwork is removed. The protrusions of the board embedded in the concrete provide an excellent connection with the structure.
Selon la présente invention la planche: - est en béton de ciment et de fibres; - consiste en un béton né langé avec un compostant élastique tel que par exemple un polymère approprié; - conporte des saillies de section en forme de queue d'aronde écartées les unes des autres et s'étendant sur toute la longueur de la planche; - comporte des passages pour des fers d'armature en porte-b-faux sur la planche et devant être noyés dans le béton coulé derrière; - a une section en forme de V; - comprend sur les deux côtés des saillies rendues solidaires du béton coulé et/ou à incorporer dans le béton sur le côté en contact; - comprend une couche d'isolation sur le côté opposé aux saillies adhérant à la planche;; - présente une structure à trois couches de telle sorte que la couche d'isolation est encadrée par deux planches disposées synétriquenent l'une par rapport à l'autre. According to the present invention, the board: - is made of cement and fiber concrete; - consists of a concrete born changed with an elastic compostant such as for example a suitable polymer; - has section projections in the form of a dovetail spaced from each other and extending over the entire length of the board; - Has passages for rebars in cantilever on the board and to be embedded in the concrete poured behind; - has a V-shaped section; - comprises on both sides of the projections made integral with the poured concrete and / or to be incorporated into the concrete on the side in contact; - includes a layer of insulation on the side opposite the projections adhering to the board; - Has a three-layer structure so that the insulation layer is framed by two boards arranged synetrically relative to each other.
La planche peut servir de délimitation du joint lors de la coulée de tronçons successifs en béton tels que des chaussées, des sols de halle, des faux-planchers et analogues et également lorsqu'un autre élé nuent en béton est à couler à la suite d'un ouvrage en béton tel qu'une bordure d'une construction de pont. Dans ces cas, la planche de coffrage conporte de manière appropriée sur les deux côtés des saillies dont les unes assurent la liaison avec le tronçon et/ou l'ouvrage de base construit préalablenent et les autres la liaison avec le tronçon et/ou l'élément suivant en béton à couler. Des passages ménagés dans la planche servent à la mise en place des armatures reliant ensemble l'ouvrage de base et l'élément de construction coulé .Une planche ayant une section en forme de V offre un blocage supplémentaire par exemple entre un tronçon d'un sol de halle déjà coulé en béton et un tronçon qui fait suite à ce dernier. The board can serve as a delimitation of the joint during the pouring of successive sections of concrete such as pavements, hall floors, raised floors and the like and also when another bare element of concrete is to be poured following '' a concrete structure such as a border of a bridge construction. In these cases, the formwork board has suitably protrusions on both sides, some of which ensure the connection with the section and / or the basic structure constructed beforehand and the others the connection with the section and / or the next element in concrete to be poured. Passages made in the board are used to install the reinforcements connecting together the basic structure and the cast building element. A board having a V-shaped section provides additional blocking, for example between a section of a hall floor already poured in concrete and a section that follows it.
Une planche en béton de ciment et de fibres ou en béton né langé avec un polymère approprié procure peu d'isolation thermique. Lorsqu'une isolation thermique plus puissante est souhaitée eu niveau des appuis audessus des ouvertures ménagées dans la maçonnerie, il sera possible d'utiliser des planches munies de prince abord d'une couche d'isolation supplémentaire telle qu'une couche en laine de verre ou en polystyrène expansible . Des unités de planches sur lesquelles la couche d'isolation est encadrée selon l'invention par deux planches symétriquement opposées, sont destinées à être mises en oeuvre dans le domaine des joints de dilatation. A concrete board made of cement and fibers or of concrete born swadded with an appropriate polymer provides little thermal insulation. When more powerful thermal insulation is desired at the level of the supports above the openings made in the masonry, it will be possible to use planks provided with a prince first of an additional layer of insulation such as a layer of glass wool or in expandable polystyrene. Board units on which the insulation layer is framed according to the invention by two symmetrically opposite boards, are intended to be used in the field of expansion joints.
Une unité de ce genre dont la couche d'isolation offre une capacité suffisante, permet d'éviter avantageusement des joints ouverts.A unit of this kind, the insulation layer of which provides sufficient capacity, advantageously avoids open joints.
L'invention n'est pas limitée par de sirrples dimensions de planche : elle peut être appliquée de la même manière à des panneaux de coffrage. The invention is not limited by small plank dimensions: it can be applied in the same way to formwork panels.
