Abstract

Method making it possible to convert the lost spaces by demolishing only part of the roof and without causing any building work in the existing building. This technique consists in introducing, sliding on purlins 2, joining and fixing industrially produced truncated structures 1 of the supporting tie-beam type in the existing frame 4, forming ribs 5 and 6 (Figure 12), joining and crossbracing the latter by means of truss girders 7 and 8 and wind-bracing girders 9, cutting the triangulation beams 11 in the habitable area, and finally putting the joists 13 into position to receive the flooring 15.

Description

DESCRIPTION a) Titre de l'invention
Procédé de transformation de charpentes industrielles en bois à comble perdu en comble à usage d'habitation par adjonction d'éléments industrialises en bois.DESCRIPTION a) Title of the invention
Process for transforming industrial timber framing from a lost roof to a roof for residential use by adding industrialized wooden elements.

b) Indication du domaine technique de l'invention
Transformation des charpentes industrielles en bois, dont la triangulation ne permet pas l'aménagement de comble, en charpente-bois avec comble à usage d'habitation c) Etat de la technique antérieure et problème posé
Les méthodes actuelles de transformation de comble sont complexes et onéreuses et nécessitent des travaux importants de dépose et repose de la toiture, avec adjonction de poteaux métalliques dans les pièces d'habitation des appartements existants, poteaux reposant souvent sur une dalle en béton non-prévue pour reprendre ces efforts ponctuels. D'autres méthodes consistent à faire supporter aux chaînages en béton armé ceinturant toute la construction, des efforts ponctuels importants issus de poutres métalliques ou structuresbois porteuses. Ces chaînages n'étant pas conçus pour reprendre ces efforts ponctuels.b) Indication of the technical field of the invention
Transformation of industrial wood frames, whose triangulation does not allow the development of an attic, into a timber frame with an attic for residential use c) State of the prior art and problem posed
Current methods of attic transformation are complex and expensive and require significant work of removal and installation of the roof, with the addition of metal poles in the living rooms of existing apartments, poles often resting on an unexpected concrete slab. to resume these ad hoc efforts. Other methods consist in making the reinforced concrete chains surrounding the entire construction bear significant point forces from metal beams or load-bearing timber structures. These linkages are not designed to take up these punctual efforts.

d) Exposé de l'invention dégageant la solution apportée
Ce procédé permet un travail rapide, rationnel et utilise la technique usuelle de fabrication et mise en oeuvre des charpentes industrielles en bois bien connue et totalement dominée quant aux calculs de résistance.d) Statement of the invention releasing the solution provided
This process allows a fast, rational work and uses the usual technique of manufacturing and implementation of industrial wood frames well known and totally dominated in terms of resistance calculations.

Le résultat souhaité est obtenu sans dépose totale de la toiture et sans intervenir dans les appartements existants. The desired result is obtained without total removal of the roof and without intervening in existing apartments.

Le procédé consiste à introduire des structures industrielles en bois aites "à entrait porteur" dans la toiture après découverture d'une petite partie de celle-ci et de les accoler aux structures industrielles existantes, dont le profil et les sections de bois les composant ne permettent pas la création de pièces d'habitation. The process consists in introducing industrial wooden structures with "load-bearing" into the roof after uncovering a small part of it and joining them to existing industrial structures, whose profile and sections of wood composing them not allow the creation of living rooms.

Lesphénomènes vibratoires et le fluage de l'ensemble de la structure sous l'effet des charges d'exploitation du comble sont supprimés par la création de deux nervures intermédiaires constituées par le triplage des structures industrielles en bois dites "à entrait porteur" et par l'adjonction de deux poutres treillis longitudinales reliant les nervures entre elles ainsi que celles-ci aux murs pignons.  The vibrational phenomena and the creep of the entire structure under the effect of the operating loads of the roof space are eliminated by the creation of two intermediate ribs formed by the tripling of industrial wooden structures called "load-bearing" and by l 'addition of two longitudinal truss beams connecting the ribs together and these to the gable walls.

Ces deux poutres longitudinales constituent deux appuis supplémentaires, outre les appuis normaux des murs, pour l'ensemble des structures industrielles en bois dltes "à entrait porteur". These two longitudinal beams constitute two additional supports, in addition to the normal supports of the walls, for all the industrial wooden structures "with load-bearing entry".

Une fois les structures à entrait porteur solidarisées aux structures existantes par vissage, et l'ensemble des nervures-poutres treillis mises en place, la suppression des contrefiches situées dans la partie habitable est réaliséeaprès la recouverture et le contreventement de la toiture. Once the load-bearing structures joined to the existing structures by screwing, and all the ribs-lattice beams put in place, the removal of the struts located in the habitable part is carried out after the covering and bracing of the roof.

f) Exposé détaillé - mode de réalisation
Transformation des charpentes composées de structures industrielles en pios (figure 1) initialement prévues pour supporter uniquement les charges permanentes de couverture et plafond ainsi que les surcharges climatiques (neige et vent) en charpentes pouvant supporter en plus des charges et surcharges ci-dessus décrites les surcharges d'exploitation engendrées par la création de piéces d'habitation dans le volume de la charpente. (Figure 2).f) Detailed presentation - embodiment
Transformation of frameworks composed of industrial structures into pios (figure 1) initially intended to support only the permanent loads of cover and ceiling as well as climatic overloads (snow and wind) into frames which can support in addition to the loads and overloads described above operating overloads caused by the creation of living spaces in the volume of the frame.
