Description
POUTRE MIXTE ALVEOLAIREALVEOLAR JOINT BEAM
La présente invention concerne une poutre mixte sur base de profilés en acier et d'une dalle en béton collaborante.The present invention relates to a composite beam based on steel profiles and a collaborating concrete slab.
La construction mixte béton-acier a de tout temps été bien adaptée à des sollicitations statiques et dynamiques exceptionnelles. Pour ce type de construction, on soude des goujons sur l'aile supérieure d'un profilé en acier servant de support au plancher. Après la coulée du plancher, les goujons sont noyés dans le béton, alors que les poutrelles se retrouvent en entier à l'air libre. Ces rangées de poutrelles peuvent ensuite être cachées par de faux plafonds, disposés à une certaine distance sous les poutres pour pouvoir abriter les tuyauteries et conduites des systèmes d'éclairage, de climatisation, d'eau, d'électricité, etc.Mixed concrete-steel construction has always been well suited to exceptional static and dynamic stresses. For this type of construction, studs are welded to the upper wing of a steel profile that supports the floor. After pouring the floor, the studs are embedded in the concrete, while the beams are found entirely in the open air. These rows of beams can then be hidden by false ceilings, placed at a certain distance under the beams to be able to shelter the pipes and conduits of lighting, air conditioning, water, electricity, etc. systems.
La présente invention a comme but de proposer une poutre, qui, tout en étant de hauteur minimale pour ce genre de construction, facilite le passage des gaines et des tuyauteries de toute sorte et qui soit particulièrement bien adaptée à la construction mixte. Ce but est atteint par la poutre mixte selon l'invention telle qu'elle est caractérisée dans la revendication 1. Des variantes d'exécution préférentielles sont décrites dans les revendications dépendantes. L'invention sera mieux comprise à l'aide de dessins qui en montrent de manière non-limitative des formes d'exécution possibles. Il est représenté: - dans les figures la, lb et le, des vues de côté et des coupes schématiques à travers 3 poutres conformes à la présente invention; - dans la figure 2a, une vue de côté d'une poutrelle découpée, pouvant être utilisée pour réaliser la poutre mixte de la présente invention; et - dans la figure 2b, différents schémas de découpe.The present invention aims to provide a beam, which, while being of minimum height for this type of construction, facilitates the passage of ducts and pipes of all kinds and which is particularly well suited to mixed construction. This object is achieved by the composite beam according to the invention as it is characterized in claim 1. Preferential alternative embodiments are described in the dependent claims. The invention will be better understood with the aid of drawings which show in a non-limiting manner possible embodiments. It is shown: - in Figures la, lb and le, side views and schematic sections through 3 beams according to the present invention; - In Figure 2a, a side view of a cut beam, which can be used to make the composite beam of the present invention; and - in Figure 2b, different cutting diagrams.
On distingue en Fig.l une poutre 1, constituée par deux demi-profilés 2 et 3 de dimension différente. Ces deux demi-profilés sont orientés de la même façon, à savoir en T renversé. La semelle 5 de la section supérieure 3, à savoir la petite section, est soudée sur l'âme 4 de la grande section 2 qui constitue la partie inférieure. Des évidements 8 sont prévus dans l'âme 4 de la section inférieure de façon à faciliter la pose de toutes sortes de gaines, conduites et câblages. Ces évidements 8 ont de préférence une forme telle qu'expliquée à l'aide de la Fig.2 et sont obtenus de la façon suivante :We distinguish in Fig.l a beam 1, consisting of two half-sections 2 and 3 of different size. These two half-sections are oriented in the same way, namely in inverted T. The sole 5 of the upper section 3, namely the small section, is welded to the core 4 of the large section 2 which constitutes the lower part. Recesses 8 are provided in the core 4 of the lower section so as to facilitate the laying of all kinds of sheaths, conduits and cables. These recesses 8 preferably have a shape as explained with the aid of FIG. 2 and are obtained in the following way:
Une poutrelle 11, par exemple du type IPE ou HE, obtenue par laminage est découpée le long d'un tracé trapézoïdal 12 en deux parties égales ce qui minimise au maximum les chutes 13 et donc le gaspillage de matières premières. D'autres schémas de découpe à amplitude modifiée ou dissymétrique, représentés à laA beam 11, for example of the IPE or HE type, obtained by rolling is cut along a trapezoidal line 12 into two equal parts which minimizes as much as possible the falls 13 and therefore the waste of raw materials. Other modified or asymmetrical amplitude cutting diagrams, shown in
Fig.2b, sont possibles mais qui, pour les derniers, ne donnent pas deux parties égales.Fig.2b, are possible but which, for the latter, do not give two equal parts.
Le profilé laminé de base peut varier en hauteur, section et hauteur de découpe selon les besoins statiques et géométriques. La section supérieure par contre a une hauteur unique adaptée à l'épaisseur de la dalle. La semelle 5 de la section supérieure constitue la semelle supérieure de la section mixte sur laquelle vient s'appuyer la dalle en béton armé 6. L'âme 7 de cette section supérieure, qui est intégrée dans la dalle en béton a la fonction de connecteur et remplace donc le système de goujons classiques. L'âme 7 de la section supérieure est pourvue de trous 9, généralement oxycoupés, qui permettent de faire passer des armatures. D'autre part la découpe supérieure 10, qui a un module de 150 mm, permet de poser des armatures en treillis soudés. Cette découpe 10 peut être de façon non- limitative, de différents types : alvéolaire à angles aigus (Fig. la), alvéolaire à angles droits (Fig. lb) ou perforée (Fig. le).The basic laminated profile can vary in height, section and cutting height according to static and geometric needs. The upper section on the other hand has a unique height adapted to the thickness of the slab. The sole 5 of the upper section constitutes the upper sole of the mixed section on which the reinforced concrete slab 6 rests. The core 7 of this upper section, which is integrated into the concrete slab has the function of connector and therefore replaces the conventional stud system. The core 7 of the upper section is provided with holes 9, generally flame-cut, which allow the reinforcement to pass through. On the other hand, the upper cutout 10, which has a module of 150 mm, makes it possible to lay welded mesh reinforcements. This cut 10 can be non-limiting, of different types: honeycomb with acute angles (Fig. La), honeycomb with right angles (Fig. 1b) or perforated (Fig. Le).
La méthode décrite dans la présente invention pour la fabrication de la section mixte permet de créer une section dissymétrique spécialement adaptée à la construction mixte. En effet, la semelle supérieure d'une poutre mixte est généralement localisée près de l'axe neutre plastique et est soumise de ce fait à une très faible sollicitation. D'où l'intérêt de la présente invention de réduire à un minimum cette section. Un autre avantage de l'invention est de supprimer complètement l'usage des goujons.The method described in the present invention for manufacturing the mixed section makes it possible to create an asymmetrical section specially adapted for mixed construction. Indeed, the upper flange of a composite beam is generally located near the plastic neutral axis and is therefore subject to very low stress. Hence the interest of the present invention in reducing this section to a minimum. Another advantage of the invention is to completely eliminate the use of studs.
