Abstract
Description
L'invention se rapporte aux bâtiments et, plus particulièrement, à ceux qui sont destinés à des usages industriels et commerciaux.The invention relates to buildings and, more particularly, to those which are intended for industrial and commercial uses.
Elle a pour objet une ossature constituée à partir d'un petit nombre de types d'éléments préfabriqués en béton, de forme rectiligne, donc relativement faciles à transporter. Cette ossature destinée à recevoir la couverture, éventuellement par l'intermédiaire de pannes, présente, par rapport aux charpentes métalliques souvent utilisées dans les bâtiments industriels, les avantages inhérents au béton (inaltérabilité, stabilité au feu, etc...), tout en étant, grâce à ses particularités structurelles, compétitive sur le plan des prix de fabrication et de pose. En outre, elle présente un aspect esthétique attrayant et, utilisant un nombre relativement réduit de poteaux, laisse le sol dégagé sur de grandes surfaces.It relates to a frame made up of a small number of types of precast concrete elements, of rectilinear shape, therefore relatively easy to transport. This frame intended to receive the cover, possibly by means of purlins, has, compared to the metal frames often used in industrial buildings, the advantages inherent in concrete (inalterability, fire stability, etc.), while being, thanks to its structural features, competitive in terms of manufacturing and installation prices. In addition, it has an attractive aesthetic appearance and, using a relatively small number of posts, leaves the ground clear over large areas.
On connaît déjà, par FR-A-489802, les ossatures porteuses constituées par un assemblage d'éléments préfabriqués en ciment armé, à savoir colonnes et poutres, destinés à supporter des dalles de planchers en ciment armé. FR-A-1111844 décrit un procédé de construction de telles ossatures, selon lequel les poutres s'encastrent dans des encoches verticales ménagées à l'extrémité supérieure du poteau de support.We already know, from FR-A-489802, the load-bearing structures constituted by an assembly of prefabricated elements of reinforced cement, namely columns and beams, intended to support slabs of reinforced cement floors. FR-A-1111844 describes a method of constructing such frameworks, according to which the beams fit into vertical notches formed at the upper end of the support post.
Ces ossatures constituent des structures lourdes, complexes et difficiles à mettre en place. Elles conviennent au support des charges considérables qui correspondent à un plancher, mais ne résolvent pas le problème de la réalisation d'une ossature de support de couverture qui soit apte à concurrencer une charpente métallique.These frames constitute heavy structures, complex and difficult to set up. They are suitable for supporting considerable loads which correspond to a floor, but do not solve the problem of producing a roof support frame which is capable of competing with a metal frame.
Les fermes traditionnelles qui portent le faîte d'un comble telles que décrites par exemple dans le "Larousse du XXe siècle" édité à Paris en 1930, tome III, pages 450-451, comprennent des pièces horizontales, appelées entraits ou tirants, qui absorbent la composante horizontale des poussées exercées par la couverture.The traditional farms which carry the roof of an attic as described for example in the "Larousse du XXe siècle" published in Paris in 1930, volume III, pages 450-451, include horizontal pieces, called ties or tie rods, which absorb the horizontal component of the thrusts exerted by the cover.
L'invention propose de résoudre le problème susvisé au moyen d'une ossature porteuse constituée par un assemblage d'éléments préfabriqués en béton armé verticaux et horizontaux de forme sensiblement parallélepipédique, jouant le rôle d'un support de couverture traditionnelle comportant, de façon connue en soi, un réseau de poutres et de fermes soutenu par des poteaux et absorbant la composante horizontale des poussées exercées par la couverture, caractérisée par le fait que ce résultat est obtenu sans devoir munir les fermes des éléments horizontaux traditionnels qui absorbent la dite composante horizontale, que ledit réseau comprend des poutres faîtières et sablières, que certains au moins des noeuds dudit réseau et, avantageusement, un noeud sur deux le long de la poutre, ne comporte pas de poteau et que les poutres sont constituées en une seule pièce et chacune des fermes est constituée de deux demi-fermes dont les extrémités en regard s'appuient obliquement sur les faces respectives de chaque poutre, de part et d'autre d'un évidement ménagé dans la tranche supérieure de l'épaisseur de la poutre, ledit évidement autorisant le passage de fers incorporés à la poutre et aux demi-fermes, du béton étant coulé dans ledit évidement pour lier lesdits fers entre eux et deux éléments de béton appliqués sur les faces respectives de la poutre, ménageant chacun une échancrure trapézoïdale dont la petite base est en bas et dans laquelle se coince la section de même forme de l'extrémité de chaque demi-ferme, la poutre ayant elle-même une section droite de même forme et que lesdits éléments sont constitués par des augets en béton solidaires des faces respectives de chaque poutre aux noeuds sans poteau, tandis qu'à chaque noeud du réseau qui comporte un poteau, lesdits éléments sont obtenus en conformant ledit poteau de manière qu'il ait une tête parallélépipédique dont l'extrémité supérieure est sensiblement située dans le plan défini par les tranches supérieures des demi-fermes et des poutres, ladite tête étant munie de deux feuillures verticales disposées en croix dans lesquelles s'engagent respectivement les portions terminales des demi-fermes et des poutres qui aboutissent audit noeud.The invention proposes to solve the aforementioned problem by means of a load-bearing framework constituted by an assembly of prefabricated elements of vertical and horizontal reinforced concrete of substantially parallelepiped shape, playing the role of a traditional roofing support comprising, in known manner in itself, a network of beams and trusses supported by poles and absorbing the horizontal component of the thrusts exerted by the roof, characterized in that this result is obtained without having to provide the trusses with the traditional horizontal elements which absorb the said horizontal component , that said network comprises ridge beams and sand pits, that at least some of the nodes of said network and, advantageously, one node out of two along the beam, does not have a post and that the beams are made in one piece and each trusses is made up of two half trusses whose opposite ends bear obliquely on the respective faces s of each beam, on either side of a recess formed in the upper edge of the thickness of the beam, said recess allowing the passage of irons incorporated into the beam and the half-trusses, concrete being poured into said recess to link said bars between them and two concrete elements applied to the respective faces of the beam, each providing a trapezoidal notch whose small base is at the bottom and in which the section of the same shape is wedged at the end of each semi-firm, the beam itself having a cross section of the same shape and that said elements consist of concrete troughs secured to the respective faces of each beam at the nodes without posts, while at each node of the network which has a pole, said elements are obtained by shaping said pole so that it has a parallelepiped head whose upper end is substantially situated in the plane defined by the upper edges of the half-trusses and beams, said head being provided with two vertical rabbets arranged in a cross in which respectively engage the terminal portions of the half-trusses and beams which terminate at said node.
D'autres particularités, ainsi que les avantages de l'invention apparaîtront clairement à la lumière de la description ci-après.Other particularities, as well as the advantages of the invention will become clear in the light of the description below.
Au dessin annexé:
- la figure 1 est une vue en perspective d'une ossature de bâtiment conforme à un mode d'exécution préféré de l'invention ; et
- la figure 2 est une vue en perspective de trois noeuds de l'ossature, dont deux comportent un poteau.
- Figure 1 is a perspective view of a building frame according to a preferred embodiment of the invention; and
- Figure 2 is a perspective view of three nodes of the frame, two of which have a post.
L'ossature représentée à la figure 1 est, à titre d'exemple, destinée à la réalisation d'un magasin rectangulaire de 80 m de long et 48 m de large. Elle est constituée de poutres faîtières 2-3-4 et sablières 1-5 et de demi-fermes transversales en béton armé telles que 6-7-8-9, 10-11-12-13, supportées par des poteaux en béton armé tels que 14-19.The frame shown in Figure 1 is, by way of example, intended for the realization of a rectangular store 80 m long and 48 m wide. It is made up of ridge beams 2-3-4 and sand pits 1-5 and transverse reinforced concrete half-trusses such as 6-7-8-9, 10-11-12-13, supported by reinforced concrete posts. such as 14-19.
Chacun des deux murs-pignons comporte, par exemple, un poteau 14-15-16 tous les 20 m tandis que chacun des deux longs-pans comporte un poteau, tel que 14-17-20, tous les 12 m.Each of the two gable walls comprises, for example, a post 14-15-16 every 20 m while each of the two long sections has a post, such as 14-17-20, every 12 m.
On voit que, suivant une particularité importante de cette ossature, le long d'une poutre longitudinale 1 à 5, dans l'intervalle entre deux poteaux 15-18 il y a une file de demifermes. On pourrait d'ailleurs prévoir deux ou trois files de demi-fermes dans cet intervalle.We see that, according to an important feature of this framework, along a
En définitive, d'une part, chaque demi-ferme franchit, sans aucun appui, un intervalle d'environ 20 m, d'autre part, tous les appuis d'une demi-ferme sur deux ou plus (telle que 10 ou 11) sont réalisés sans poteau et résultent de l'assemblage avec une poutre longitudinale.Ultimately, on the one hand, each half-farm crosses, without any support, an interval of approximately 20 m, on the other hand, all the supports of one half-farm on two or more (such as 10 or 11 ) are made without a post and result from assembly with a longitudinal beam.
L'avantage important de cette structure est que le sol de chacune des mailles de 12x20 m ne comporte qu'un poteau à chaque coin, sans poteau central ou intermédiaire. Outre qu'elle dégage le sol, la réduction du nombre des poteaux constitue évidemment une économie.The important advantage of this structure is that the ground of each of the 12x20 m meshes has only one post at each corner, with no central or intermediate post. In addition to clearing the ground, reducing the number of posts is obviously a saving.
Les demi-fermes étant des pièces droites à appui dénivelé, elles ne développent aucune poussée horizontale à leurs extrémités, en dépit de leur inclinaison ; cela rend possible la suppression des poteaux à certains noeuds.The half-trusses being straight support pieces uneven, they develop no horizontal thrust at their ends, despite their inclination; this makes it possible to delete the posts at certain nodes.
Comme le montre la figure 2, l'assemblage entre la poutre longitudinale 2-2" et deux demi-fermes 21-22 s'effectue au moyen d'un ancrage 23 constitué de fers soudés entre eux et respectivement solidaires des extrémités en regard des deux demi-fermes et des deux bords opposés d'un évidement ménagé dans la poutre. Ces fers peuvent être rectilignes et soudés, comme dans le cas de la figure, ou en forme de boucles d'ancrage traditionnelles, ou autres et ils sont recouverts d'un clavetage en béton protecteur qui comble l'évidement.As shown in FIG. 2, the assembly between the longitudinal beam 2-2 "and two half-trusses 21-22 is carried out by means of an
Des augets 24-25, avantageusement en béton et solidaires des deux faces respectives de la poutre, recoivent les extrémités des demi-fermes 21-22, qui se trouvent ainsi positionnées correctement dans le prolongement l'une de l'autre et ne peuvent tourner latéralement après pose. Ces augets ne subissent aucune poussée latérale.Buckets 24-25, advantageously made of concrete and integral with the two respective faces of the beam, receive the ends of the half-trusses 21-22, which are thus positioned correctly in the extension of one another and cannot rotate laterally after installation. These buckets do not undergo any lateral thrust.
L'assemblage entre les poutres (portion 2-2') et les deux demi-fermes correspondant à un noeud qui comporte un poteau 18 s'effectue de la manière suivante :
- La tête du poteau est munie de deux feuillures verticales perpendiculaires entre elles 180-181, de section trapézoïdale et dont le fond (petite base du trapèze) a une largeur qui correspond respectivement à la largeur d'une poutre et à celle d'une demi-ferme. La hauteur de la
feuillure 180 correspond à celle d'une poutre, tandis que la hauteur de lafeuillure 181 correspond à celle d'une demi-ferme. Les liaisons entre la poutre et les deux demi-fermes s'effectuent, comme aux noeuds sans poteau, par des fers tels que 183 protégés par un recouvrement de béton. Ces feuillures transmettent la charge verticale au poteau et assurent le guidage de la poutre (ou de la demi-ferme) qui, une fois posée, ne peut plus tourner.
- The head of the post is provided with two vertical rebates perpendicular to each other 180-181, of trapezoidal section and the bottom (small base of the trapezoid) has a width which corresponds respectively to the width of a beam and that of a half -closed. The height of the
rabbet 180 corresponds to that of a beam, while the height of therabbet 181 corresponds to that of a half-truss. The connections between the beam and the two half-trusses are made, as at knots without a post, by irons such as 183 protected by a concrete covering. These rebates transmit the vertical load to the pole and guide the beam (or the half-truss) which, once installed, can no longer rotate.
Dans certains cas, pour des raisons de commodité, on remplacera une feuillure par deux augets.In certain cases, for reasons of convenience, a rebate will be replaced by two buckets.
On notera que les dimensions des mailles données à titre d'exemple ne sont nullement limitatives et que les pentes des poutres et des demi-fermes peuvent être de valeurs et de signes quelconques. De même le nombre des demi-fermes fixées sur une même poutre variera suivant le projet.It will be noted that the dimensions of the meshes given by way of example are in no way limiting and that the slopes of the beams and of the half-trusses can be of any value and of signs. Similarly the number of half-trusses fixed on the same beam will vary depending on the project.
