Abstract
Description
La présente invention concerne un dispositif d'ossature mixte du type décrit dans le brevet principal nO 8903067 du 6 mars 1989. The present invention relates to a mixed framework device of the type described in main patent No. 8903067 of March 6, 1989.
Le présent additif à l'invention concerne un dispositif de connexion un procédé de réalisation de ce dernier, des domaines d'application. The present additive to the invention relates to a connection device, a method for producing the latter, fields of application.
La figure 1 représente le dispositif. Les figures 2 à 9 représentent plusieurs types de dispositif. La figure 10 représente un profilé ouvert. Figure 1 shows the device. Figures 2 to 9 show several types of device. Figure 10 shows an open profile.
Jusqu'à présent la connexion entre le profilé (1) et la dalle en béton (2) était assurée par un connecteur rapporté, fixé le plus souvent par soudage. Until now, the connection between the profile (1) and the concrete slab (2) has been ensured by an attached connector, most often fixed by welding.
Le dispositif selon l'invention permet d'éliminer toute opération de soudage du connecteur puisque ce dernier est obtenu directement dans la masse du profilé. Profilé et connexion forment un seul élément. The device according to the invention makes it possible to eliminate any welding operation of the connector since the latter is obtained directly in the mass of the profile. Profile and connection form a single element.
La connexion est réalisée dans la partie noyée du profilé et est assurée par des saillies dont la géométrie et l'orientation permet de s opposer aux effets de glissement et de soulèvement de la dalle béton par rapport au profilé, sans addition d'autres éléments étrangers au profilé. The connection is made in the submerged part of the profile and is ensured by projections whose geometry and orientation allow to oppose the effects of sliding and lifting of the concrete slab relative to the profile, without the addition of other foreign elements to the profile.
Le dispositif permet la répartition rationnelle et maitrisée des contraintes mécaniques de manière à ne pas dépasser les valeurs admissibles de chaque matériau. The device allows the rational and controlled distribution of mechanical stresses so as not to exceed the admissible values of each material.
Sur un même profilé il peut être envisagé une ou plusieurs géométries de saillies permettant ainsi de répondre exactement aux sollicitations locales que doit équilibrer un connecteur. One or more projection geometries can be envisaged on the same profile, thus making it possible to respond exactly to local stresses that a connector must balance.
On sait notamment que les sollicitations que doit équilibrer le connecteur sont maximales dans les zones d'about et minimales en milieu de travée, la géométrie des connecteurs d'un même profilé pourra alors varier le long du profilé en fonction de la répartition de l'effort ou être constante dans un souci de standardisation, de simplification des calculs et mise en oeuvre. We know in particular that the stresses that the connector must balance are maximum in the end zones and minimum in the middle of the span, the geometry of the connectors of the same profile can then vary along the profile depending on the distribution of the effort or be constant for the sake of standardization, simplification of calculations and implementation.
La fonction connectrice peut alors être rationnellement assurée. The connecting function can then be rationally ensured.
La présente invention permet une infinité de cas de constructions autorisées par le sens de coulage. The present invention allows an infinite number of construction cases authorized by the direction of flow.
L'écartement des profilés est modulable, la distance entre profilé et le fond de coffrage est modulable, l'épaisseur de la dalle est modulable. The spacing of the profiles is adjustable, the distance between the profile and the bottom of the formwork is adjustable, the thickness of the slab is adjustable.
Deux profilés délimitent un espace dans lequel l'épaisseur de la dalle peut être identique ou différente des espaces voisins par le jeu des caractéristiques rhéologiques du béton frais et par la perte de charge qu'entraine l'espace libre entre le profilé et le fond de moule. Two profiles delimit a space in which the thickness of the slab can be identical or different from neighboring spaces by the play of the rheological characteristics of fresh concrete and by the pressure drop caused by the free space between the profile and the bottom of mold.
Le dispositif peut alors mécaniquement répondre exactement et rationnellement aux efforts mécaniques causés par des actions externes et internes. The device can then mechanically respond exactly and rationally to the mechanical stresses caused by external and internal actions.
Le profilé peut être brut de laminage, figures 2,4. The profile can be roughly rolled, Figures 2,4.
Le profilé peut être issu de la découpe d'un autre profilé figures 3, 5, 6, 7. La découpe peut être droite et continue, parallèle à l'axe longitudinal du profilé, elle peut aussi être ordonnée pour former des créneaux et des redans, ces derniers constituants les saillies après torsion. The profile can come from the cutting of another profile Figures 3, 5, 6, 7. The cutting can be straight and continuous, parallel to the longitudinal axis of the profile, it can also be ordered to form slots and steps, the latter constituting the projections after twisting.
Le profilé peut être reconstitué soudé sans que le connecteur soit soudé, le profilé peut être formé d'un profil mince ouvert ou fermé obtenu par formage d'une plaque mince par exemple d'acier inoxydable tel que représenté à la figure 9. The profile can be reconstituted welded without the connector being welded, the profile can be formed from a thin open or closed profile obtained by forming a thin plate, for example of stainless steel as shown in FIG. 9.
Un matériau rigidifiant par exemple du polyuréthane pouvant inclure des armatures longitudinales peut être logé à l'intérieur du profil mince. A stiffening material, for example polyurethane, which may include longitudinal reinforcements, can be housed inside the thin profile.
La présente invention permet d'envisager l'utilisation de plusieurs matériaux ou éléments constitutifs par exemple de la dalle (2). Ces matériaux peuvent être préfabriqués et posés en fond de coffrage par exemple : carreaux de céramiques, prédalles bétons, moquette routière, revêtement de sol. The present invention makes it possible to envisage the use of several materials or constituent elements for example of the slab (2). These materials can be prefabricated and placed at the bottom of the formwork, for example: ceramic tiles, concrete slabs, road carpet, floor covering.
Les éléments préfabriqués peuvent alors remplir les fonctions de coffrages, de couche d'usure, d'isolation thermique, phonique, d'étanchéité, de propreté, d'esthétique. The prefabricated elements can then fulfill the functions of formwork, wear layer, thermal, sound insulation, sealing, cleanliness, aesthetics.
Le procédé d'exécution de la connexion consiste à réaliser dans un premier temps des coupes au plasma, à l'oxycoupage, au laser, à l'eau, à l'emporte pièces, au cisaillement, certaines coupes peuvent être suffisamment larges pour permettre le passage d'armature. Les saillies à leur base ont une largeur permettant la résistance mécanique en service, minimisant l'énergie de déformation, par torsion au moyen d'un couple de torsion défini par deux efforts opposés de même intensité et dont les points d'application respectifs se situent sur deux saillies successives. The method of performing the connection consists in first making plasma cuts, flame cutting, laser, water, cookie cutters, shearing, some cuts may be wide enough to allow the frame passage. The projections at their base have a width allowing mechanical strength in service, minimizing the deformation energy, by torsion by means of a torsional torque defined by two opposite forces of the same intensity and whose respective points of application are located. on two successive projections.
Le dispositif selon l'invention peut être utilisé, après durcissement du béton, comme éléments successifs appuyés sur des longrines ou de chaussée directement appuyés sur une couche de forme par appui partiel ou généralisé des profilés. La légèreté de la construction mixte permet d'envisager des éléments de plusieurs mètres carrés de surface. Facilement maniable le sens du coulage permet de coffrer la surface de roulement de la chaussée et de répondre ainsi aux impératifs de sécurité et d'esthétique. La construction mixte libère un espace entre le sol et le béton utilisable pour le passage des réseaux. The device according to the invention can be used, after hardening of the concrete, as successive elements supported on sills or road directly supported on a form layer by partial or general support of the profiles. The lightness of the mixed construction makes it possible to envisage elements of several square meters of surface. Easily manageable, the direction of the pouring makes it possible to form the running surface of the roadway and thus meet the requirements of safety and aesthetics. The mixed construction frees up a space between the ground and the concrete usable for the passage of the networks.
Les matériaux du dispositif à savoir acier pour le profilé et béton pour la dalle peuvent être remplacés par d'autres matériaux respectivement aluminium, bois, poutres de béton armé ou précontraint, composite, pour le profilé et béton haute performance, béton de fibres, matière organique, composite pour la dalle. The materials of the device, namely steel for the profile and concrete for the slab can be replaced by other materials respectively aluminum, wood, reinforced or prestressed concrete beams, composite, for the profile and high performance concrete, fiber concrete, material organic, composite for the slab.
