Abstract
Description
L'invention concerne un procédé pour réaliser dans une excavation, un ouvrage comportant un mur extérieur en limite de propriété et des murs de refend. The invention relates to a method for producing, in an excavation, a structure comprising an exterior wall at the property line and cross walls.
Une technique connue pour réaliser le mur extérieur consiste à réaliser un talus stable en bordure de la limite, à réaliser de place en place des massifs en pied de talus, à descendre des voiles préfabriqués dans le talus, en limite de propriété, pour réaliser le mur extérieur en assurant au fur et à mesure la stabilité des voiles par des liaisons de soutien établies entre les voiles et les massifs, à réaliser les murs de refend. et à supprimer les massifs et les liaisons devenus inutiles. A known technique for making the exterior wall consists in making a stable embankment at the edge of the boundary, in carrying out massifs from place to place at the foot of the embankment, in descending prefabricated sails in the embankment, at the property boundary, to carry out the exterior wall, gradually ensuring the stability of the sails by supporting links established between the sails and the walls, to make the cross walls. and to remove massifs and links that have become useless.
La présente invention vise à simplifier cette technique. The present invention aims to simplify this technique.
Selon l'invention, on fixe provisoirement des banches aux emplacements désignés pour un ou plusieurs des murs de refend, on met en place une ou des voiles préfabriqués en avant de ces banches pour constituer une partie du mur extérieur en utilisant les banches pour assurer la stabilité de ce ou ces voiles, on coule du béton dans les banches pour réaliser le ou les murs de refend concernés et on retire les banches après durcissement du béton, en répétant les opérations en tant que de besoin. According to the invention, the formwork is temporarily fixed to the locations designated for one or more of the crosswalls, one or more prefabricated sails are put in front of these formwork to form part of the exterior wall using the formwork to ensure the stability of this or these sails, concrete is poured into the formwork to make the affected wall or walls and the formwork is removed after the concrete has hardened, repeating the operations as necessary.
Les figures schématiques du dessin joint illustrent la cinématique d'un exemple non limitatif de mise en oeuvre du procédé de l'invention. The schematic figures of the attached drawing illustrate the kinematics of a nonlimiting example of implementation of the method of the invention.
Sur les figures: - la fig. 1 est une vue du talus réalisé en bordure de propriété; - la fig. 2 montre deux semelles de fondation réalisées en pied du talus; - la fig. 3 montre des saignées réalisées dans le talus; - la fig. 4 montre des banches en cours de mise en place dans les saignées et sur les semelles; - la fig. 5 montre les banches en place, fixées aux semelles; - la fig. 6 montre des voiles mis en place dans le talus en avant des banches, à la limite de propriété, stabilisés par les banches; - la flg. 7 montre les banches en cours de remplissage pour le moulage des murs de refend et, - la flg. 8 montre un mur de refend ainsi réalisé, après enlèvement de la banche correspondante. In the figures: - fig. 1 is a view of the slope made on the edge of the property; - fig. 2 shows two foundation soles made at the foot of the slope; - fig. 3 shows grooves made in the slope; - fig. 4 shows forms in the process of being installed in the grooves and on the soles; - fig. 5 shows the formwork in place, fixed to the soles; - fig. 6 shows sails set up in the slope in front of the formwork, at the property line, stabilized by the formwork; - fig. 7 shows the forms being filled for the molding of the cross walls and, - flg. 8 shows a cross wall thus produced, after removal of the corresponding form.
Le mode opératoire consiste, après avoir creusé l'excavation, à - terrasser l'excavation en réalisant un talus stable (1) en périphérie de l'excavation (2) dont la limite est schématisée par une clôture (3), (figi); - réaliser la ou les semelles (4) de l'un ou de plusieurs des murs de refend en béton en dehors du talus (fig.2); - faire une saignée verticale (5) dans le talus en prolongement de chaque semelle (fig. 3); - mettre en place dans chaque saignée et sur la semelle correspondante un train de banches (6) fermées. serrées et ferraillées (fig. 4); - assurer la reprise des efforts de butées entre les banches et la fondation, par des liaisons provisoires appropriées (7), fig. 5) par exemple des tirants; - faire descendre dans le talus en limite de propriété au moins un voile préfabriqué (8) en excavant le merlon de talus situé devant le voile (fig. 6); - assurer le butonnage définitif du ou des voiles préfabriqués en coulant dans le ou les trains de banches (6) le béton (9) du ou des murs de refend perpendiculaires (fig. 7); - retirer les banches (6) qui ont servi à mouler le ou les murs de refend (9) (fig. 8). The operating mode consists, after having dug the excavation, to - excavate the excavation by making a stable slope (1) on the periphery of the excavation (2), the limit of which is shown diagrammatically by a fence (3), (figi) ; - make the sole (s) (4) of one or more of the concrete cross walls outside the slope (fig.2); - make a vertical groove (5) in the slope as an extension of each sole (fig. 3); - set up in each groove and on the corresponding sole a train of closed forms (6). tight and scrapped (fig. 4); - ensure the resumption of the abutment efforts between the formwork and the foundation, by suitable temporary connections (7), fig. 5) for example tie rods; - lower at least one prefabricated veil (8) into the slope at the edge of the property, excavating the slope merlon located in front of the veil (fig. 6); - ensure the final butonnage of the prefabricated wall (s) by pouring the concrete (9) of the perpendicular cross-section wall (s) into the rail (s) (6); - remove the formwork (6) which was used to mold the cross wall (s) (9) (fig. 8).
I1 est entendu que l'on peut appliquer le procédé à un ou simultanément à plusieurs des voiles du mur extérieur en utilisant le nombre de trains de banches approprié. It is understood that the method can be applied to one or simultaneously to several of the sails of the external wall by using the appropriate number of formwork trains.
Les opérations sont renouvelées en tant que de besoin et on scelle au moment approprié les Joints entre les voiles du mur extérieur. The operations are repeated as necessary and the Joints between the sails of the exterior wall are sealed at the appropriate time.
L'invention s'applique notamment à la construction de parkings ou de caves. The invention is particularly applicable to the construction of parking lots or cellars.
