Abstract

The present invention relates to a method for readapting dwellings comprising apartments of small or large living surface by uniting in duplex rooms of two superimposed floors, and a construction element for implementing such method. According to the invention, two façade openings, belonging to rooms to be united, are vertically interconnected by a staircase housed in a construction element (19) built in the façade, of which the horizontal cross-section is defined by an outline, polygonal or arc of a circle, exinscribed to the outer section of the staircase cage, which outline is extended, in general by straight lines, up to the extremities of the base, said base having a width corresponding to a modular spacing such that the vertical loads may be reported to the façade posts of the construction.

Description

Procédé et éléments constructifs de réadaptation d'habi¬ tats . Process and constructive elements of rehabilitation of homes.
La présente invention concerne l'habitat dit collectif. A l'époque du développement du type d'habitat en grands en¬ sembles, la crise du logement a conduit à réaliser des lo¬ gements standard généralement groupés par un ou deux ty¬ pes dans un même bâtiment. La demande actuelle porte sur une typologie plus variée et une actualisation du loge¬ ment. Elle varie dans le temps avec l'évolution de la fa¬ mille. La satisfaction de cette demande est obtenue ac¬ tuellement par des réalisations immobilières qui impli¬ quent en tout ou en grande partie le transfert des deman¬ deurs de logements plus vastes dans d'autres bâtiments.The present invention relates to so-called collective housing. At the time of the development of the type of housing in large apartments, the housing crisis led to the creation of standard accommodation generally grouped by one or two types in the same building. The current demand relates to a more varied typology and an updating of the accommodation. It varies over time with the evolution of the family. The satisfaction of this demand is currently obtained by real estate projects which involve all or a large part of the transfer of applicants for larger dwellings in other buildings.
La présente invention a pour' but d'éviter ces déplace- ' ments de population en intervenant ponctuellement, sur. les seuls logements pour lesquels la demande et les be¬ soins nécessitent une modification de la répartition du volume habitable.The present invention 'to avoid such displacement' population elements intervening punctually on. the only dwellings for which demand and needs require a change in the distribution of living space.
La solution envisagée couramment pour accroître ou dimi¬ nuer le nombre de pièces habitables d'un logement est la réunion de deux logements contigus situés au même étage par percement de mur séparatif lors de la libération d'un logement. Mais ce type d'opportunité est rare. L'élargis¬ sement des solutions par réunion sous forme d'apparte¬ ments dits "duplex" de logements situés à deux étages su¬ perposés en les réunissant par un escalier intérieur se heurte à la difficulté d'implantation dudit escalier. Cet¬ te difficulté d'implantation résulte, d'une part, de la réduction de surface habitable qu'elle entraîne et, d'au¬ tre part, de la nécessité de percer les planchers exis¬ tants qui constituent souvent des éléments participant à la stabilité mécanique de la construction et dans les¬ quels sont souvent noyées les canalisations de chauffage par le sol .The solution currently envisaged for increasing or decreasing the number of habitable rooms in a dwelling is the meeting of two contiguous dwellings located on the same floor by piercing a dividing wall when a dwelling is released. But this type of opportunity is rare. The enlargement of the solutions by meeting in the form of so-called "duplex" apartments of dwellings located on two floors su¬ superposed by joining them together by an internal staircase comes up against the difficulty of installing said staircase. This installation difficulty results, on the one hand, from the reduction in living space that it entails and, on the other hand, from the need to pierce the existing floors which often constitute elements participating in the mechanical stability of the construction and in which the heating pipes are often buried by the ground.
La présente invention a pour but de résoudre ces problè¬ mes et elle a pour objet un procédé de réadaptation qui permet de modifier la typologie dans l'habitat compor¬ tant des appartements aussi bien de faible que de forte surface habitable par réunion en duplex de pièces si¬ tuées à deux étages superposés , caractérisé en ce que l'on met en intercomraunication verticale deux ouvertures en façade, appartenant à des pièces à réunir, par un esca¬ lier logé dans un élément constructif rapporté en façade.The purpose of the present invention is to solve these problems and it relates to a rehabilitation process which makes it possible to modify the typology in the habitat comprising apartments, both small and large, living space by duplex meeting of rooms si¬ killed on two superimposed floors, characterized in that two vertical openings in front intercomunication, belonging to rooms to be joined together, by a staircase housed in a constructive element attached to the front.
Lorsque les ouvertures en façade ne sont pas des portes- fenêtres donnant sur un balcon, cas qui est choisi de pré¬ férence dans toute la mesure du possible pour éviter la démolition des balcons, au moins une allège des fenêtres situées sur la largeur en façade de l'élément est démo¬ lie pour donner accès à un palier réalisé dans l'élément, palier sur lequel débouche la cage d'escalier.When the openings on the front are not French windows leading to a balcony, a case which is preferably chosen as far as possible to avoid the demolition of the balconies, at least one light of the windows located across the width on the front of the element is demolished to give access to a landing made in the element, a landing onto which the staircase opens.
Selon un mode de réalisation préférentiel, l'élément cons¬ tructif rapporté en façade a une section horizontale dont la base correspond à un écartement modulaire tel que deux poteaux porteurs éloignés d'une trame ou d'un multiple de trame de la construction puissent reprendre les charges verticales de l'élément. Dans le cas où la largeur de la trame des poteaux porteurs de la construction contre la¬ quelle est appliqué l'élément constructif englobe un écar¬ tement entre poteaux ne correspondant pas à celui utili¬ sé pour la détermination de la largeur de la base de la section horizontale, une structure porteuse en drapeau est ajoutée sur au moins un côté de cette base. La sec¬ tion horizontale de l'élément constructif est de préféren¬ ce symétrique par rapport à la médiane de la base et, la cage d'escalier étant aménagée dans le sommet extérieur de la section, ladite section est définie par un tracé, polygone ou arc de cercle, exinscrit à la section exté- rieure de la cage d'escalier qui est prolongé, en géné¬ ral par des droites, jusqu'aux extrémités de la base. Il en résulte que cette section peut être un triangle rectan¬ gle isocèle, un trapèze dont les trois côtés sont tan¬ gents au cercle exinscrit à la cage d'escalier, un polygo¬ ne dont les quatre côtés sont tangents audit cercle, un trapèze curviligne dont la petite base est constituée par un arc dudit cercle exinscrit ou une courbe en anse de pa¬ nier dont le sommet est tangent à ce cercle exinscrit. Par cercle exinscrit à la cage d'escalier,, on entend un cercle centré sur l'axe du noyau et ayant un rayon égal à la largeur minimale des marches. Les sections voisines de la base de la section de l'élément constructif laissées libres par la cage d'escalier peuvent être aménagées en volumes habitables avec vitrages dans les faces de l'élé¬ ment constructif.According to a preferred embodiment, the constructive element added on the front has a horizontal section, the base of which corresponds to a modular spacing such that two supporting posts distant from a frame or a frame multiple of the construction can resume the vertical loads of the element. In the case where the width of the frame of the supporting posts of the construction against which the building element is applied includes a spacing between posts not corresponding to that used for determining the width of the base of the horizontal section, a flag-bearing structure is added on at least one side of this base. The horizontal section of the constructive element is preferably symmetrical with respect to the median of the base and, the staircase being arranged in the outer top of the section, said section is defined by a line, polygon or circular arc, not included in the external section of the stairwell which is extended, in general by straight lines, to the ends of the base. As a result, this section can be an isosceles right triangle, a trapezoid whose three sides are tangent to the circle exinscribed to the stairwell, a polygo¬ ne whose four sides are tangent to said circle, a trapezoid curvilinear whose small base is constituted by an arc of said exinscribed circle or a curve in handle of pa¬ nier whose apex is tangent to this exinscribed circle. The expression circle outside the staircase means a circle centered on the axis of the core and having a radius equal to the minimum width of the steps. The neighboring sections of the base of the section of the constructive element left free by the stairwell can be arranged in habitable volumes with glazing in the faces of the constructive element.
Lorsque l'étage supérieur du duplex n'est pas l'étage su¬ périeur de la construction, le toit de l'élément construc¬ tif rapporté est,de préférence, aménagé en balcon ouvert pour l'étage immédiatement au-dessus.When the upper floor of the duplex is not the upper floor of the building, the roof of the added building element is preferably arranged in an open balcony for the floor immediately above.
La présente invention a également pour objet l'élément constructif rapporté en façade pour la mise en oeuvre du procédé.The present invention also relates to the constructive element added on the front for the implementation of the method.
La section horizontale de cet élément est définie par un tracé polygone ou arc de cercle, exinscrit à la section extérieure de la cage d'escalier, tracé qui est prolongé, en général par des droites, jusqu'aux extrémités de la ba¬ se, cette base ayant une largeur correspondant à un écar- tement modulaire tel que les charges verticales puissent être reportées sur les poteaux de façade de la construc¬ tion.The horizontal section of this element is defined by a polygon or arc of a circle outline, not included in the outside section of the stairwell, a layout which is extended, in general by straight lines, to the ends of the base, this base having a width corresponding to a modular spacing such that the vertical loads can be transferred to the facade posts of the construc¬ tion.
Selon une autre caractéristique de l'invention, l'élé¬ ment constructif comporte le long d'au moins l'un des bords de la base de sa section une structure porteuse en drapeau pour couvrir un écartement entre poteaux supé¬ rieur à l'écartement modulaire auquel correspond l'élé¬ ment.According to another characteristic of the invention, the constructive element comprises along at least one of the edges of the base of its section a supporting structure in the form of a flag to cover a spacing between posts greater than the modular spacing to which the element corresponds.
Son ossature est constituée par au moins trois poteaux contreventés dont deux sont disposés aux deux extrémités de la base et un autre au sommet extérieur du prisme cons¬ titué par les faces en encorbellement de l'élément.Its framework is constituted by at least three braced posts, two of which are arranged at the two ends of the base and another at the outer top of the prism cons¬ constituted by the cantilevered faces of the element.
L'élément constructif rapporté en façade peut être réali¬ sé au moins partiellement in situ par assemblage d'élé¬ ments constituants préfabriqués. Des poteaux libres peu¬ vent descendre jusqu'au sol lorsque l'ossature porteuse du bâtiment est insuffisante pour absorber la charge sup¬ plémentaire de l'élément constructif rapporté. Selon un mode de réalisation préférentiel, l'élément constructif, qui est en général standard pour les grands ensembles de même conception architecturale, est préfabriqué et accro¬ ché à la ois sur les poteaux de façade de 1' immeuble et aux planchers haut du logement desservi au niveau supé¬ rieur de l'élément.The constructive element attached to the facade can be made at least partially in situ by assembling prefabricated constituent elements. Free poles can descend to the ground when the load-bearing structure of the building is insufficient to absorb the additional load of the added construction element. According to a preferred embodiment, the constructive element, which is generally standard for large complexes of the same architectural design, is prefabricated and hung in the eye on the front posts of the building and on the upper floors of the accommodation. served at the upper level of the element.
On décrira ci-après un exemple de mise en oeuvre de l'in¬ vention avec référence aux dessins ci-annexés dans les¬ quels :An example of implementation of the invention will be described below with reference to the accompanying drawings in which:
les figures 1A, 1B et 1C sont des plans au niveau de trois étages illustrant la réadaptation de trois loge¬ ments en deux duplex par application du procédé con¬ forme à l'invention et la figure 2 est une vue en élé¬ vation de la façade correspondant aux figures 1.FIGS. 1A, 1B and 1C are plans at the level of three floors illustrating the readjustment of three housings in two duplexes by application of the method according to the invention and FIG. 2 is a view in elevation of the front corresponding to figures 1.
La réadaptation envisagée porte sur trois appartements du type trois pièces-cuisine situés aux deux, trois et qua¬ trième étages d'un immeuble. La réadaptation a pour but d'ajouter une pièce I de l'appartement du troisième éta- ge à celui A du deuxième étage et une pièce II et la cui¬ sine III de l'appartement du troisième étage à l'apparte¬ ment C du quatrième étage, la troisième pièce B de l'ap¬ partement du troisième étage étant réunie par un perce¬ ment de cloison 10 à un appartement contigu du même éta¬ ge.The planned rehabilitation involves three apartments of the three-room kitchen type located on the two, three and fourth floors of a building. The purpose of the rehabilitation is to add room I to the apartment on the third floor ge to that A of the second floor and a room II and the kitchen III of the apartment of the third floor to the apartment C of the fourth floor, the third room B of the apartment of the third floor being joined through a wall opening 10 to an adjoining apartment of the same floor.
Les pièces I, B et II de l'appartement du troisième étage sont tout d'abord isolées par des cloisons séparatrices 11.Rooms I, B and II of the third floor apartment are firstly insulated by dividing partitions 11.
Les appartements occupent en façade quatre travées entre les poteaux d'ossature 12 de l'immeuble.The apartments occupy in front four spans between the studs 12 of the building.
Comme travail préparatoire, on supprime les allèges 13 des deux travées de gauche du deuxième étage, les allè¬ ges 14 des trois travées de gauche et l'allège 15 de la travée de droite du troisième étage et les allèges 16 des deux travées centrales du quatrième étage avec l'allège 17, de la travée de droite. Certaines des allèges telles que 14' , 16', éventuellement les vitrages qui les surmon¬ tent, peuvent être conservées ou remplacées par des pa¬ rois en glace pour isoler la pièce qu'elles délimitent du palier de l'élément de construction rapporté, la communi¬ cation se faisant par une porte 18.As preparatory work, we remove the lighters 13 of the two left spans of the second floor, the lighters 14 of the three left spans and the lighters 15 of the right span of the third floor and the lighters 16 of the two central spans of the fourth floor with sill 17 , from the right bay. Some of the lighters such as 14 ′, 16 ′, possibly the glazing which overhangs them, can be preserved or replaced by glazed walls to isolate the part which they delimit from the bearing of the added construction element, the communication takes place through a door 18.
Un élément constructif est désigné dans son ensemble par la référence 19. Il présente une section horizontale en triangle isocèle rectangle dont la base correspond à la largeur de deux travées courantes entre poteaux 12 de la façade. Du fait que l'élément constructif est appliqué contre une partie de façade comportant une travée plus large au droit des allèges 15 et 17, l'accrochage de l'é¬ lément constructif sur le poteau 12' se fait par l'inter¬ médiaire d'une structure en drapeau (prolongement de la façade latérale ou de la base du triangle rectangle isocè¬ le) . La structure porteuse de l'exemple représenté comporte six poteaux dont deux 20 aux extrémités de la base, l'un 21 au milieu de cette base qui vient au droit du poteau 12 central, un autre 22 au sommet du dièdre et deux au¬ tres 23 au milieu des faces latérales, cet ensemble étant contreventé soit dans le plan des façades , soit dans l'é¬ paisseur des planchers. La référence 35 désigne une stru- ture porteuse en drapeau ajoutée sur un côté de la base de l'élément constructif pour compenser la surlargeur de la travée correspondant aux allèges 15 et 17 et permet¬ tre l'accrochage de l'élément constructif sur le poteau 12' .A constructive element is designated as a whole by the reference 19. It has a horizontal section in an isosceles right triangle whose base corresponds to the width of two current spans between posts 12 of the facade. Due to the fact that the constructive element is applied against a part of the facade comprising a wider span in line with the sills 15 and 17, the attachment of the constructive element to the post 12 ′ is done by the intermediary of a flag structure (extension of the side façade or the base of the isocè¬ le right triangle). The supporting structure of the example shown comprises six posts, two of which 20 at the ends of the base, one 21 in the middle of this base which comes in line with the central post 12, another 22 at the top of the dihedral and two others 23 in the middle of the side faces, this assembly being braced either in the plane of the facades, or in the thickness of the floors. The reference 35 designates a flag-bearing structure added on one side of the base of the constructive element to compensate for the extra width of the span corresponding to the lighters 15 and 17 and allows the constructive element to be attached to the 12 'post.
La cage de l'escalier 24 est disposée dans le carré en¬ tre les poteaux 21, 22 et 23. A chaque étage et entre les deux groupes de poteaux 20, 21, 23 sont réalisé's deux pa¬ liers 25. Chaque palier est séparé de la cage .d'escalier soit par des cloisons pleines 26,soit par des cloisons mu¬ nies d'une porte 27 débouchant sur le palier 28' de l'esca¬ lier soit, enfin, par un garde-corps 26'. Les parois laté¬ rales de l'élément 19 comportent, dans leurs parties si¬ tuées entre les parties 20 et 23, des fenêtres 29 qui éclairent le palier 25 et la pièce attenante. D'autres fe¬ nêtres 30 dans la paroi entre les poteaux 22 et 23 éclai¬ rent la cage d'escalier. Pour alléger l'ensemble et limi¬ ter l'ombre sur les fenêtres telles que 31 (figure 2) se trouvant à l'étage inférieur, on peut ménager un vide 32 sous la volée 33 de l'escalier.The stairwell 24 is arranged in the square between the posts 21, 22 and 23. On each floor and between the two groups of posts 20, 21, 23 are made with two brackets 25. Each landing is separate of the staircase either by solid partitions 26, or by partitions provided with a door 27 opening onto the landing 28 ' of the staircase, or, finally, by a railing 26'. The lateral walls of the element 19 comprise, in their parts si¬ killed between the parts 20 and 23, windows 29 which illuminate the bearing 25 and the adjoining room.
