Abstract
Description
L'invention se rapporte à un procédé de transformation d'une charpente et aux éléments de charpente en vue de la mise en oeuvre de ce procédé.The invention relates to a method of transforming a frame and to the frame elements with a view to implementing this method.
Elle s'applique à la transformation des charpentes des combles non aménageables d'aménager ces combles.It applies to the transformation of the frames of non-convertible attics to develop these attics.
On sait que ces charpentes sont constituées d'une série de fermettes s'étendant d'un mur de façade à un autre, entre lesquelles façades, ces fermettes sont placées à faible distance les unes des autres et sont maintenues entre elles par des entretoises et contreventements d'un mur pignon à un autre et sur lesquelles fermettes, la toiture prend appui.We know that these frames consist of a series of small farms extending from one facade wall to another, between which facades, these small farms are placed at a short distance from each other and are held together by spacers and bracing from one gable wall to another and on which trusses, the roof is supported.
Les fermettes comprennent principalement une poutre horizontale dite »entrait« reliant donc les murs des façades avant et arrière et de deux pièces de bois inclinées dites »arbalétriers«, s'élevant jusqu'au fait du toit.The farmhouses mainly include a horizontal beam called "entry" therefore connecting the walls of the front and rear facades and two pieces of inclined wood called "crossbowmen", rising to the fact of the roof.
Ces fermettes sont toutefois légères et doivent donc être renforcées.These farmhouses are however light and must therefore be reinforced.
Leurs renforts consistent en une triangulation formée d'éléments dont certains, travaillant en traction depuis le sommet de la fermette, soutiennent l'entrait alors que les autres, travaillant en compression en prenant appui au pied des précédents, soutiennent, généralement en leur milieu, les arbalétriers qui sans cela seraient trop flexibles pour soutenir la toiture.Their reinforcements consist of a triangulation formed of elements of which some, working in traction from the top of the farmhouse, support the entry while the others, working in compression by taking support at the foot of the preceding, support, generally in their middle, rafters who would otherwise be too flexible to support the roof.
Cette triangulation, qui se répète à chaque fermette et qui constitue un obstacle à l'aménagement du comble, ne peut évidemment être ôtée, sans autres précautions, sans mettre en péril les arbalétriers, la couverture et le plafond.This triangulation, which is repeated at each farmhouse and which constitutes an obstacle to the development of the attic, can obviously not be removed, without other precautions, without jeopardizing the rafters, the cover and the ceiling.
En travaux neufs (brevet français A-2 411 283), avant couverture, il est bien sûr connu et aisé de prévoir des poutres s'étendant d'un mur pignon à un autre et sur lesquelles prendront appui les arbalétriers des fermettes qui, au moins dans la zone apte à constituer la partie habitable du comble, pourront alors être dépourvues de triangulation de soutien.In new works (French patent A-2 411 283), before covering, it is of course known and easy to provide beams extending from one gable wall to another and on which will support the rafters of small farms which, at less in the area capable of constituting the habitable part of the attic, can then be devoid of support triangulation.
Lors de la transformation de constructions existantes, il est évidemment possible de découvrir la charpente pour permettre le passage et la mise en place des poutres ainsi que la rectification des fermettes mais cela constitue un travail extrêmement important et coûteux qui, de plus, pendant un certain temps, expose le reste de la construction aux intempéries.During the transformation of existing constructions, it is obviously possible to discover the frame to allow the passage and the installation of the beams as well as the rectification of the farmhouses but this constitutes an extremely important and expensive work which, moreover, during a certain time, expose the rest of the construction to the weather.
Afin de permettre le retrait de la triangulation sans pour autant déposer le toiture, il est connu de placer, au préalable, sous les arbalétriers, des piliers de soutien. Malheureusement, ces piliers ne peuvent, quant à eux, pas prendre appui sur l'entrait qui n'avait pas été prévu pour une telle charge mais doivent donc descendre jusqu'à la première dalle en béton qu'il rencontre dans la construction et qui constitue généralement le plancher du dernier étage de la construction dans les pièces duquel étage, ces piliers ne peuvent pas toujours être facilement masqués par des placards ou cloisons.In order to allow the removal of the triangulation without depositing the roof, it is known to place, beforehand, under the rafters, support pillars. Unfortunately, these pillars cannot, for their part, be supported on the entry which had not been planned for such a load but must therefore descend to the first concrete slab which it meets in construction and which generally constitutes the floor of the last floor of the construction in the rooms of which floor, these pillars cannot always be easily hidden by cupboards or partitions.
Un résultat que l'invention vise à obtenir est un procédé de transformation de charpente qui sans mettre en péril les arbalétriers et la couverture, ne nécessite ni de déposer cette couverture, ni de prévoir sous les arbalétriers des piliers qui, pour leur appui, doivent descendre jusqu'à une dalle en béton qui, de surcroît, elle non plus, n'a pas été prévue pour une telle charge.One result that the invention aims to obtain is a frame transformation process which, without endangering the rafters and the cover, does not require either depositing this cover or providing under the rafters pillars which, for their support, must descend to a concrete slab which, moreover, it too was not intended for such a load.
A cet effet, l'invention a pour objet un procédé du type précité, notamment caractérisé en ce qu'avant retrait des éléments de triangulation de chaque arbalétrier:
- - tout d'abord, on fixe entre l'arbalétrier et l'entrait, d'au moins plusieurs fermettes, une coulisse verticale, composée de pièces de bois, dites »bracons«, solidarisant l'arbalétrier et l'entrait,
- - dans le même temps, on apporte dans le comble et on engage dans les coulisses des poutres que l'on a préalablement scindées en plusieurs tronçons et on scelle dans chacun des murs pignons l'une des extrémités de la poutre dont on relie les tronçons par des moyens de liaison sous chacun desquels on a fixé un poinçon,
- - ensuite, on saisit la base de chacun des poinçons par l'une des extrémités de deux tirants dont, au moins indirectement, on relie les autres extrémités à celles des tronçons de poutre situés de part et d'autre du poinçon considéré,
- - enfin, par manoeuvre de tendeurs appropriés, on fait agir les tirants qui, par réaction sur leur poinçon avec lequel ils forment une triangulation, soutiendront la poutre qui elle-même alors, au moins indirectement, soutiendra les arbalétriers, la toiture et les entraits,
- - après contrôle de la levée de la toiture, on dépose alors la triangulation initiale des fermettes puis on habille le comble.
- - first of all, a vertical slide, made up of pieces of wood, called "bracons", is fixed between the crossbowman and the entry, at least several small farms, joining the crossbowman and the entry,
- - At the same time, we bring in the roof and we engage in the slides beams that have been previously split into several sections and we seal in each of the gable walls one of the ends of the beam whose sections are connected by connecting means under each of which a punch has been fixed,
- - then, the base of each of the punches is grasped by one of the ends of two tie rods, of which, at least indirectly, the other ends are connected to those of the beam sections situated on either side of the punch considered,
- - finally, by maneuvering suitable tensioners, the tie rods are made to act, which, by reaction on their punch with which they form a triangulation, will support the beam which itself then, at least indirectly, will support the crossbowmen, the roof and the ties ,
- - after checking the lifting of the roof, the initial triangulation of the trusses is then deposited, then the roof is dressed.
Elle à également pour objet les éléments de charpente en vue de la mise en oeuvre de ce procédé.It also relates to the structural elements for the implementation of this process.
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:
- - figure 1: un comble non aménageable avant la transformation selon le procédé de l'invention,
- - figure 2: ce comble après sa transformation selon le procédé de l'invention,
- - figure 3: une coupe selon Ill-lll de la figure 2,
- - figure 4: à plus grande échelle, un détail d'une fermette transformée.
- FIG. 1: an attic which cannot be converted before transformation according to the method of the invention,
- - Figure 2: this roof after its transformation according to the method of the invention,
- FIG. 3: a section along Ill-III of FIG. 2,
- - Figure 4: on a larger scale, a detail of a transformed farmhouse.
En se reportant au dessin, on voit que la charpente 1, comprend une série de fermettes 2 s'étendant d'un mur de façade 3 à un autre 4 entre lesquelles façades 3, 4, ces fermettes sont placées à faible distance »D«, les unes des autres, et sur lesquelles la toiture (non représentée) prend appui.Referring to the drawing, it can be seen that the
Les fermettes 2 comprennent principalement une poutre horizontale 5 dite »entrait« reliant les murs des façades 3, 4 et deux pièces de bois inclinées dites »arbalétriers« 6, 7 s'élevant jusqu'au faît du toit.The
La charge »P« du toit sollicite en flexion ces arbalétriers 6, 7 qui comme les entraits doivent donc être soutenus.The load "P" of the roof biases these
A cet effet, avant transformation, les arbalétriers 6, 7 et l'entrait 5 sont reliés entre eux par des éléments 8, 9, 10, 11 formant une triangulation.For this purpose, before transformation, the
Selon une caractéristique essentielle du procédé selon l'invention, avant retrait de la triangulation,
- - tout d'abord, on fixe, entre l'arbalétrier 6 et/ ou 7 et l'entrait 5 d'au moins plusieurs
fermettes 2 et de préférence de toutes lesfermettes 2, une coulisse verticale 12 formée par l'interstice entre deux pièces de 13, 14 dites »bracons«, fixées chacune par leurs extrémités à l'entrait et à l'arbalétrier correspondant, par tout moyen connu tel que clouage, vissage, agrafage, rivetage, boulonnage ou même soudure dans le cas de fermettes métalliques,bois - - dans le même temps, on apporte dans le comble et on engage, dans les
coulisses 12, despoutres 15 que l'on a préalablement scindées en plusieurstronçons 16,17,18,19 chacun de dimensions réduites en fonction des possibilités d'accès et on scelle dans chacun des 20, 21, l'une des extrémités de lamurs pignons poutre 15 dont on relie lestronçons 16, 17, 18, 19 par des moyens de 22, 23, 24, sous chacun desquells on fixe unliaison poinçon 25,26 ou 27, - - ensuite, on saisit la base de chacun des poinçons par l'une des extrémités de deux
31, 32 dont, directement ou indirectement, on relie les autres extrémités aux extrémités des tronçons de poutre situés de part et d'autre du poinçon considéré,tirants - - enfin, on place un cordeau témoin entre les pignons et on trace des repères sur chaque fermette, puis on agit sur les tirants qui, par réaction sur leur poinçon avec lequel ils forment une triangulation, soutiendront la poutre qui, elle-même, pourra alors directement ou indirectement soutenir les arbalétriers et tant la toiture que le futur plancher.
- - First of all, a
vertical slide 12 formed by the gap between two is fixed between thecrossbowman 6 and / or 7 and theentry 5 of at leastseveral farms 2 and preferably of allfarms 2 pieces of 13, 14 called "bracons", each fixed by their ends to the tie and the corresponding crossbowman, by any known means such as nailing, screwing, stapling, riveting, bolting or even welding in the case of small farms metallic,wood - - At the same time, we bring in the roof and we engage, behind the
scenes 12,beams 15 that have been previously divided intoseveral sections 16,17,18,19 each of reduced dimensions according to the possibilities of access and one seals in each of the 20, 21, one of the ends of thegable walls beam 15 of which thesections 16, 17, 18, 19 are connected by connecting 22, 23, 24, under each of which one fixes ameans 25, 26 or 27,punch - - Then, the base of each of the punches is grasped by one of the ends of two
31, 32 of which, directly or indirectly, the other ends are connected to the ends of the sections of beam located on either side of the punch considered ,tie rods - - Finally, we place a witness line between the gables and we draw marks on each farm, then we act on the tie rods which, by reaction on their punch with which they form a triangulation, will support the beam which, itself, can then directly or indirectly support the rafters and both the roof and the future floor.
Dès que la titure s'est levée d'au moins quelques millimètres, après un éventuel renforcement du plancher, on autorise alors la dépose des éléments 8, 9, 10, 11, de la triangulation initiale qui est devenue inutile.As soon as the titration has risen by at least a few millimeters, after a possible reinforcement of the floor, the elements 8, 9, 10, 11 are then allowed to be removed, from the initial triangulation which has become useless.
Les coulisses verticales 12 seront maintenues pour éviter tout déplacement latéral de la poutre et de son système de mise sous tension.The
Ces coulisses et/ou les poutres 15 pourront d'ailleurs servir de support pour l'habillage 37, des parois verticales de la pièce à aménager, tel des plaques de plâtre, contreplaqué, aggloméré, etc.... et pour soutenir, si besoin est, une traverse 38 que recevra des renforts 39 de plancher 40. Ce renfort pourra être construit de même manière qui la poûtre 15.These slides and / or the
L'habillage masquera alors toute cette ossature.The covering will then mask all this framework.
Les renforts de plancher pourront être conçus en plusieurs tronçons reliés et soustendus de manière semblable à la poutre 15.The floor reinforcements may be designed in several sections connected and subtended in a manner similar to the
Outre le procédé de transformation, l'invention concerne également les coulisses 12 et les poutres 15 ainsi que les éléments qui les composent et qui donc assurent la mise en oeuvre du procédé.In addition to the transformation process, the invention also relates to the
A ce sujet, les moyens de liaison 22, 23, 24 des tronçons de poutres 16, 17, 18, 19 pourront consister en des axes d'articulation mais, de préférence, ils consisteront en de simples fourches portées en tête des poinçons 25, 26, 27 dans lesquelles les extrémités des dits tronçons seront simplement déposées et placées en appui l'une sur l'autre.In this regard, the
Quant aux tendeurs 41 des tirants dont les sections pourront être de forme circulaire ou prismatique, ils pourront avantageusement être constitués par une pièce pourvue de taraudages à pas contraires.As for the
Pour leur assemblage aux points de rappel, les extrémités des tirants seront de préférence pourvues d'un moyen démontable tel un boulon ou un crochet s'engageant dans un oeillet d'une patte.For their assembly at the return points, the ends of the tie rods will preferably be provided with a removable means such as a bolt or a hook engaging in an eyelet of a tab.
Bien que l'invention ait été décrite à partir d'une toiture à deux versants, elle peut évidemment, même si la surface habitable récupérée est plus faible, s'appliquer aux toitures ayant plus de deux versant, ou moins certains des tronçons de poutre étant alors inclinés pour reporter sur le dessus des pignons, la charge des fermettes.Although the invention has been described from a two-slope roof, it can obviously, even if the recovered living area is smaller, apply to roofs with more than two slopes, or some of the beam sections then being inclined to transfer onto the top of the gables, the load of the farms.
