Abstract

Prefabricated slabs for the construction of buildings comprise vertical slabs having a male fitting 113 of square cross-section at the top of the slab and may have a female cavity 114 equipped with a flat fitting 113 at the bottom of the slab; as well as floor slabs 200 which for their part have a cavity which is open at one edge and on both sides of the slab and wherein is situated a U-shaped fitting 201. During the assembling operation, the male fitting is inserted into the U fitting 201 and then into the female cavity 114 whilst being held fast by the flat fitting 113. These fittings are then welded together, and the next floor may be installed without any delay. The cavities are then filled with a fluid mortar which protects the fittings against corrosion. <IMAGE>

Description

La présente invention se rapporte aux panneaux préfabriqués pour construction d'immeubles, qui permettent de construire un tel immeuble en assemblant des panneaux préfabriqués à l'avance.The present invention relates to prefabricated panels for building construction, which make it possible to construct such a building by assembling prefabricated panels in advance.

Il est connu dans l'industrie du batiment de préfabriquer des panneaux en béton, qui servent par exemple de mur de façade, de mur de refend, de pignon, ou de plancher. Il existe différentes méthodes pour assembler entre-eux ces panneaux, et la plus connue consiste à mettre en place les panneaux d'un premier niveau en réservant entre-eux certains intervalles adaptés, complétés par un ferraillage en rond à béton constituant ainsi une armature secondaire. On coule ensuite du béton dans cette ossature, et lorsque le chainage ou l'assemblage ainsi obtenu sont secs, on peut monter le niveau supérieur. Il est bien clair qu'un tel procédé nécessite un main d'oeuvre qualifiée rare et coûteuse pour procéder à un tel assemblage. Par ailleurs, au temps nécessaire pour l'assemblage, s'ajoute le temps de séchage du béton. Même si l'on peut employer la main- d'oeuvre ailleurs, où à d'autres taches, sur un chantier suffisamment important, on immobilise un matériel coûteux, notamment un nombre important d'étais pendant toutes ces opérations.It is known in the building industry to prefabricate concrete panels, which serve for example as a facade wall, a dividing wall, a gable, or a floor. There are different methods for joining these panels together, and the best known is to install the panels at a first level, reserving between them certain suitable intervals, supplemented by reinforcement in the form of concrete rounds thus constituting a secondary reinforcement. . Concrete is then poured into this framework, and when the chaining or the assembly thus obtained are dry, the upper level can be raised. It is quite clear that such a process requires a rare and expensive skilled workforce to carry out such an assembly. In addition, the time required for assembly is added to the drying time of the concrete. Even if the labor can be employed elsewhere, or at other tasks, on a sufficiently large site, one immobilizes an expensive material, in particular a significant number of props during all these operations.

On a déjà proposé des pièces métalliques incorporées dans les panneaux, accessibles par des ouvertures sur les chants de ces panneaux, et qui permettent un assemblage plus rapide des panneaux par fixation des armatures de l'un sur celles du panneau contigu. Toutefois les dispositifs ainsi décrits jusqu'à présent ne permettent pas de dépasser dans la pratique une hauteur de construction supérieure à un, voir deux, niveaux.We have already proposed metal parts incorporated in the panels, accessible by openings on the edges of these panels, and which allow faster assembly of the panels by fixing the frames of one on those of the adjoining panel. However, the devices thus described so far do not allow in practice to exceed a construction height greater than one, or even two, levels.

Pour permettre des constructions de plus grande hauteur, l'invention propose un panneau préfabriqué pour construction d'immeubles, du type vertical, caractérisé en ce qu'il comprend au moins une ferrure mâle de section carrée, dont une partie est noyée dans le corps du panneau, et dont l'autre partie émerge du chant supérieur du panneau en étant parallèle aux chants latéraux et de longueur supérieure à l'épaisseur d'un panneau de plancher.To allow constructions of greater height, the invention provides a prefabricated panel for building construction, of the vertical type, characterized in that it comprises at least one male fitting of square section, part of which is embedded in the body of the panel, and the other part of which emerges from the upper edge of the panel while being parallel to the lateral edges and of length greater than the thickness of a floor panel.

Sur la figure 1 un panneau de façade supérieur 100 est placé au-dessus d'un panneau de façade inférieur 300, dans la position qu'il occupe lors du montage, juste avant la descente pour procéder à l'assemblage final. Entre ces deux panneaux se situe un panneau de plancher 200, dont on n'a représenté qu'une ferrure 201 pour la compréhension de la figure. Ce panneau 200 sera représenté plus complétement dans les figures suivantes, qui sont des vues en coupe selon divers plans au niveau des ferrures d'assemblage.In FIG. 1, an upper front panel 100 is placed above a lower front panel 300, in the position it occupies during assembly, just before the descent to proceed with the final assembly. Between these two panels is a floor panel 200, of which only one fitting 201 has been shown for the understanding of the figure. This panel 200 will be shown more fully in the following figures, which are sectional views along various planes at the level of the assembly fittings.

Dans l'exemple décrit, les panneaux de façade sont du type composite à structure extérieure flottante. Ils comportent des parois internes, respectivement 110 et 310 pour les panneaux 100 et 300, et des parois externes, respectivement 112 et 312, séparées des parois internes par des couches isolantes respectivement 111 et 311.In the example described, the facade panels are of the composite type with floating exterior structure. They have internal walls, respectively 110 and 310 for the panels 100 and 300, and external walls, respectively 112 and 312, separated from the internal walls by insulating layers respectively 111 and 311.

Le panneau inférieur 300 comprend à sa partie supérieure des tubes ou profilés métalliques de section carrée par exemple tels que 313, qui sont noyés dans le béton et débordent du chant supérieur de la paroi interne 310. Il comprend également des drageoirs tels que 314, qui permettent de délimiter un jeu volontaire avec la face inférieure de la pièce qui vient prendre appui sur le chant du panneau.The lower panel 300 comprises, at its upper part, metal tubes or sections of square section, for example such as 313, which are embedded in the concrete and project beyond the upper edge of the internal wall 310. It also includes bezers such as 314, which allow to define a voluntary play with the underside of the part which comes to rest on the edge of the panel.

En se plaçant à un stade de l'assemblage où le panneau 300 est déjà maintenu en place par des moyens non représentés tels que des étais, on place ensuite sur ce panneau le panneau de plancher horizontal 200 qui comporte une cavité à l'intérieur de laquelle est scellée la pièce métallique 201, qui a la forme d'un U muni de deux ailes. Les ailes et une partie des bras verticaux du U sont scellées dans le béton, et le restant de la ferrure vient faire saillie dans l'ouverture du panneau de manière à présenter à l'intérieur du U un espace libre dont la section est sensiblement égale à celle du tube 313.By placing oneself at a stage of assembly where the panel 300 is already held in place by means not shown, such as struts, the horizontal floor panel 200 which then has a cavity inside is then placed on this panel. which is sealed the metal part 201, which has the shape of a U provided with two wings. The wings and part of the vertical arms of the U are sealed in the concrete, and the rest of the fitting protrudes into the opening of the panel so as to present inside the U a free space whose section is substantially equal. to that of tube 313.

Ainsi, lorsque l'on pose le panneau de plancher, le tube 313 vient s'enfoncer dans la ferrure 201, ce qui maintient fermement ensemble les deux panneaux.Thus, when the floor panel is installed, the tube 313 sinks into the fitting 201, which firmly holds the two panels together.

Le chant supérieur de la paroi 310 comporte en outre des drageoirs tels que 314 qui permettent de délimiter un jeu volontaire entre ce chant et la face inférieure du panneau de plancher. Ce jeu permettra ultérieurement de couler un produit de remplissage, tel qu'un mortier relativement fluide, qui n'aura aucun rôle mécanique de maintien, mais qui servira à protéger les ferrures métalliques de l'oxydation et à présenter un joint d'aspect régulier. Ce produit peut être aussi une résine collante si besoin est.The upper edge of the wall 310 further comprises bezers such as 314 which make it possible to define a voluntary clearance between this edge and the underside of the floor panel. This set will later allow a filling product to be poured, such as a relatively fluid mortar, which will have no mechanical holding role, but which will serve to protect the metal fittings from oxidation and to present a seal of regular appearance. . This product can also be a sticky resin if necessary.

Dès ce stade, on peut solidariser les ferrures 313 et 201, par exemple en soudant à l'arc les parties de ces ferrures qui sont en contact et qui sont accessibles de l'extérieur, c'est-à-dire les deux ailes latérales de la tranche supérieure de la ferrure 201 avec le pourtour du tube 313.From this stage, the fittings 313 and 201 can be secured, for example by arc welding the parts of these fittings which are in contact and which are accessible from the outside, that is to say the two lateral wings. of the upper edge of the fitting 201 with the periphery of the tube 313.

Lorsque l'assemblage de ce premier niveau est ainsi terminé, par l'achèvement de la pose du plancher sur les chants supérieurs des panneaux de façade, on peut procéder à l'édification du niveau supérieur en venant placer les panneaux de façade 100. La paroi extérieure 112 de ce panneau de façade comprend une aile 115 qui déborde vers le bas, afin de venir prendre place dans un dégagement 315, formé par la paroi extérieure 312 dont l'extrémité supérieure s'arrête à une distance déterminée en dessous de l'extrémité supérieure du panneau 300. Ceci permet à l'aile 115 de venir recouvrir l'isolant 311 pour protéger celui-ci et d'offrir les étanchéités utiles.When the assembly of this first level is thus completed, by the completion of the laying of the floor on the upper edges of the facade panels, it is possible to build the upper level by placing the facade panels 100. The exterior wall 112 of this front panel comprises a wing 115 which projects downwards, in order to take place in a clearance 315, formed by the external wall 312, the upper end of which stops at a determined distance below the upper end of the panel 300. This allows the wing 115 to come and cover the insulation 311 to protect the latter and to provide useful seals.

L'isolant 111 lui vient au contact de l'isolant 311, de manière à réaliser la continuité de l'isolation thermique directement ou indirectement.The insulator 111 comes into contact with the insulator 311, so as to achieve the continuity of the thermal insulation directly or indirectly.

La paroi intérieure 110 du panneau supérieur 100 comprend elle un dégagement 116 qui permet de loger le panneau de plancher 200 inséré entre les deux panneaux de façade 100 et 300, et qui comporte la ferrure 201.The inner wall 110 of the upper panel 100 includes a clearance 116 which makes it possible to house the floor panel 200 inserted between the two front panels 100 and 300, and which comprises the fitting 201.

Cette paroi intérieure 110 comprend également une cavité 114, qui débouche sur sa face intérieure et sur le chant inférieur. A l'intérieur de cette cavité se trouve une ferrure 113 transversale, qui comprend deux ailes noyées dans le béton et une partie médiane qui traverse la cavité 114 de part en part. De cette manière lorsque l'on vient descendre le panneau de façade 100 à son emplacement, la partie du tube profilé 313 qui déborde de la face supérieure de la dalle de plancher 200 vient pénétrer dans l'ouverture 114. Elle se trouve emprisonnée entre la paroi intérieure de cette ouverture et la ferrure 113 pour laquelle ce tube s'appuie.This inner wall 110 also includes a cavity 114, which opens on its inner face and on the lower edge. Inside this cavity there is a transverse fitting 113, which comprises two wings embedded in the concrete and a middle part which crosses the cavity 114 right through. In this way, when the front panel 100 is lowered to its location, the part of the profiled tube 313 which projects from the upper face of the floor slab 200 comes into the opening 114. It is trapped between the inner wall of this opening and the fitting 113 for which this tube rests.

On peut alors solidariser la ferrure 113 avec le tube 313, par exemple par une soudure à l'arc. Sur le chant inférieur de la paroi 110, on trouve également des drageoirs tels que ceux du chant supérieur de la paroi 310, qui permettent eux aussi de délimiter un jeu volontaire entre ce champ et la face supérieure du panneau du plancher. Ce jeu permet alors de couler un mortier de remplissage, qui vient remplir aussi bien cette cavité 114, que celle où se trouve la ferrure 201, et les deux jeux volontaires entre le panneau de plancher et les panneaux de façade. Cette opération peut être effectuée à tout moment adéquat après la solidarisation des ferrures entre-elles, sans entrainer aucun retard sur la suite du chantier, puisqu'elle ne joue aucun rôle dans la solidité mécanique de l'ensemble, et sert seulement à la protection contre la corrosion et à la finition de l'assemblage.We can then secure the fitting 113 with the tube 313, for example by an arc weld. On the lower edge of the wall 110, there are also bezels such as those of the upper edge of the wall 310, which also make it possible to define a voluntary clearance between this field and the upper face of the floor panel. This game then allows a filling mortar to be poured, which fills this cavity 114 as well as that where the fitting 201 is located, and the two voluntary games between the floor panel and the front panels. This operation can be carried out at any suitable time after the fittings are joined together, without causing any delay on the rest of the site, since it plays no role in the mechanical strength of the assembly, and is only used for protection against corrosion and finish of the assembly.

Sur la figure 2 on a représenté une coupe selon un plan vertical, perpendiculaire aux panneaux de façade et formant un plan de symétrie pour les trois ferrures 113, 201 et 313. Dans cette figure, seuls les panneaux de façade et la ferrure 113 sont vus en coupe, alors que les deux autres ferrures et le panneau de plancher ne sont pas coupés, ceci pour une meilleure compréhension de la figure.In Figure 2 there is shown a section along a vertical plane, perpendicular to the facade panels and forming a plane of symmetry for the three fittings 113, 201 and 313. In this figure, only the facade panels and the fitting 113 are seen in section, while the other two fittings and the floor panel are not cut, this for a better understanding of the figure.

On remarque notamment sur cette figure le cordon de soudure 115, qui relie le sommet du tube 313, à la ferrure 113, et le cordon de soudure 203, qui relie le sommet de la ferrure 201 au tube 313.We note in particular in this figure the weld bead 115, which connects the top of the tube 313, to the fitting 113, and the weld bead 203, which connects the top of the fitting 201 to the tube 313.

On remarque également un joint d'étanchéité 202, placé entre le chant avant du panneau 200 et l'isolant 111, qui permet au mortier de remplissage de ne pas s'étaler dans l'intervalle séparant cet isolant et ce chant.There is also a seal 202, placed between the front edge of the panel 200 and the insulation 111, which allows the filling mortar not to spread out in the interval separating this insulation and this edge.

Sur la figure 3 on voit une vue en coupe selon un plan horizontal, médian du panneau de plancher 200. On remarque sur cette figure la position des joints 202 cités plus haut, et la forme en U avec deux ailes transversales de la ferrure 201. Ces ailes permettent de fixer solidement cette ferrure dans le panneau de plancher.In FIG. 3 is seen a sectional view along a horizontal, median plane of the floor panel 200. In this figure, we note the position of the joints 202 mentioned above, and the U shape with two transverse wings of the fitting 201. These wings allow this fitting to be firmly fixed in the floor panel.

Sur la figure 4 on voit une vue en coupe selon un plan horizontal, médian de la ferrure 113. On remarque sur cette figure la forme de la ferrure 113, qui présente une partie transversale allongée 117 sur laquelle s'appuie le tube 313, puis deux ailes 118 qui se recourbent une première fois vers le centre du panneau, et une deuxième fois pour se situer dans le plan médian de ce panneau, ceci afin d'affermir l'ancrage de cette ferrure dans le panneau.In FIG. 4 is seen a sectional view along a horizontal, median plane of the fitting 113. In this figure, we note the shape of the fitting 113, which has an elongated transverse part 117 on which the tube 313 rests, then two wings 118 which curl a first time towards the center of the panel, and a second time to lie in the median plane of this panel, this in order to firm the anchoring of this fitting in the panel.

On remarque également sur cette figure, ainsi que sur la figure 3, que l'intérieur même du tube 313 est rempli de mortier, afin de le protéger dans tous les cas contre la corrosion.It is also noted in this figure, as in Figure 3, that the very interior of the tube 313 is filled with mortar, in order to protect it in all cases against corrosion.

Pour fixer les murs de refend, on utilise le même procédé, et l'on a représenté sur la figure 5 une vue en coupe d'un noeud entre deux panneaux de refend 151 et 351, et deux panneaux de plancher 251 et 252.To fix the cross walls, the same method is used, and there is shown in Figure 5 a sectional view of a knot between two cross panels 151 and 351, and two floor panels 251 and 252.

La tête du panneau de refend inférieur 351 comprend une ferrure tubulaire 352, qui fait saillie vers le haut et sur laquelle viennent se fixer les ferrures des autres panneaux. Cette ferrure 352 peut être un profilé.The head of the bottom splitting panel 351 comprises a tubular fitting 352, which projects upwards and on which is fixed the fittings of the other panels. This fitting 352 can be a profile.

Les panneaux 251 et 252 comportent à l'emplacement de ce noeud, respectivement deux cavités 253 et 254, dans lesquelles font saillie deux ferrures 255 et 256. Ces ferrures sont semblables aux ferrures 201, mais elles sont moins hautes, de façon à pouvoir se superposer dans l'espace délimité par les cavités 253 et 254.The panels 251 and 252 comprise at the location of this node, respectively two cavities 253 and 254, in which two fittings 255 and 256 protrude. These fittings are similar to the fittings 201, but they are less high, so that they can be superimpose in the space delimited by the cavities 253 and 254.

On commence par poser le panneau de plancher 252 sur la tête du panneau de refend 351, en engageant la ferrure 256 sur le tube 352. On soude cette ferrure avec le tube en formant un cordon de soudure 257, puis on place le deuxième panneau de plancher 251, dont la ferrure 255 vient prendre place sur le tube 352 au-dessus de la ferrure 256. On soude alors cette ferrure 255 au tube 352 par un autre cordon de soudure 258. Selon une variante les soudures peuvent être simultanées.We start by placing the floor panel 252 on the head of the splitting panel 351, engaging the fitting 256 on the tube 352. We weld this fitting with the tube by forming a weld bead 257, then place the second panel floor 251, the fitting 255 of which takes its place on the tube 352 above the fitting 256. This fitting 255 is then welded to the tube 352 by another weld bead 258. According to a variant, the welds can be simultaneous.

Le panneau de refend supérieur 151 comporte, à l'emplacement du noeud de jonction, une cavité 152 traversée par deux ferrures paralléles 153 et 154.The upper split panel 151 comprises, at the location of the junction node, a cavity 152 crossed by two parallel fittings 153 and 154.

Dans une troisième étape, on vient placer ce panneau 151 sur les panneaux 251 et 252, en enfilant le tube 352 entre les ferrures 153 et 154. On soude ensuite ce tube à ces ferrures par deux cordons de soudure 155 et 156.In a third step, this panel 151 is placed on the panels 251 and 252, by threading the tube 352 between the fittings 153 and 154. This tube is then welded to these fittings by two weld beads 155 and 156.

On remplira ensuite, dans une étape de finition, les cavités 253, 254, et 152 avec un mortier fluide qui viendra les combler en protégeant les ferrures de l'oxydation et en offrant un bel aspect de finition. Des drageoirs sont également prévus, pour ménager entre les différents panneaux des jeux volontaires dans lesquels le mortier viendra refluer.Then, in a finishing step, the cavities 253, 254, and 152 will be filled with a fluid mortar which will fill them, protecting the fittings from oxidation and offering a nice finish. Drageers are also provided, to provide voluntary games between the various panels in which the mortar will flow back.

Sur la figure 6, on voit une vue en coupe horizontale du noeud de jonction de la figure 5, dans un plan médian de la ferrure 256. On remarque sur cette figure la forme en U munie de deux ailes de la ferrure 256, qui est bien semblable à celle de la ferrure 201 sur la figure 3.In Figure 6, we see a horizontal sectional view of the junction node of Figure 5, in a median plane of the fitting 256. We note in this figure the U shape with two wings of the fitting 256, which is very similar to that of the fitting 201 in FIG. 3.

Sur la figure 7, on a représenté une vue en coupe du noeud de jonction de la figure 5, selon un plan horizontal sensiblement médian aux ferrures 153 et 154. Les ferrures 255 et 256 n'ont pas été représentées pour la clarté de la figure.In Figure 7, there is shown a sectional view of the junction node of Figure 5, along a substantially median horizontal plane to the fittings 153 and 154. The fittings 255 and 256 have not been shown for clarity of the figure .

On remarque sur cette vue la forme des ferrures 153 et 154, qui sont simplement composées de deux lames d'acier paralléles au plan du panneau de refend 151, et qui traversent de part en part la cavité 152 pour encadrer le tube 352.Note on this view the shape of the fittings 153 and 154, which are simply composed of two steel blades parallel to the plane of the splitting panel 151, and which pass right through the cavity 152 to frame the tube 352.

Dans l'exemple représenté sur la figure 5, les deux panneaux de plancher sont fixés à un même noeud aux deux panneaux de refend, ce qui impose que les deux ferrures 255 et 256 de ces panneaux de plancher soient décalées dans le sens vertical pour pouvoir se superposer.In the example shown in Figure 5, the two floor panels are attached to the same node to the two split panels, which requires that the two fittings 255 and 256 of these floor panels are offset in the vertical direction to be able overlap.

On a représenté sur la figure 8 une vue en coupe semblable à celle de la figure 5, d'un noeud de fixation entre deux panneaux de refend et deux panneaux de plancher, mais dans un mode de fixation dit alterné où seul l'un des panneaux de plancher, ici 252, posséde une ferrure 256, qui vient se fixer au tube de départ 352 sortant du panneau de refend inférieur 351. Dans ce cas un autre noeud, situé plus loin sur le chant des panneaux de refend, comportera au contraire une ferrure solidaire du panneau de plancher 251, et racco-dée à d'autres ferrures des deux panneaux de refend.There is shown in Figure 8 a sectional view similar to that of Figure 5, of a fixing node between two splitting panels and two floor panels, but in a so-called alternating fixing mode where only one of the floor panels, here 252, has a fitting 256, which is fixed to the starting tube 352 coming out of the lower split panel 351. In this case another node, located further on the edge of the split panels, will on the contrary comprise a fitting integral with the floor panel 251, and connected to other fittings of the two split panels.

Les panneaux de façade étant fixés en tête et en pied, il est utile de les solidariser en au moins un point de leurs chants verticaux. Il en est de même à la jonction entre deux panneaux de façade, tels que 290 et 291, et un panneau de refend, tel que 190 sur la figure 9.The facade panels being fixed at the head and at the foot, it is useful to join them at at least one point of their vertical edges. The same is true at the junction between two front panels, such as 290 and 291, and a cross panel, such as 190 in FIG. 9.

Pour cela on prévoit dans les panneaux de façade, à la hauteur désirée pour la solidarisation entre-eux, respectivement deux cavités où plus 292 et 293. Le panneau de refend 290 vient pénétrer dans l'ensemble formé par ces deux cavités.For this, provision is made in the front panels, at the desired height for joining together, respectively, two cavities where more 292 and 293. The splitting panel 290 comes into the assembly formed by these two cavities.

On a fixé, lors de la préfabrication des panneaux de façade, deux ferrures, respectivement dans les cavités 292 et 293, de telle manière qu'elles soient fixées dans le panneau et qu'elles aient une partie apparente. Dans l'exemple décrit, ces ferrures 294 et 295 sont formées de portions de corniéres, dont une aile est noyée dans la masse du panneau, et dont l'autre aile affleure la surface parallélement à celle-ci.Two fittings were fixed during the prefabrication of the front panels, respectively in the cavities 292 and 293, in such a way that they are fixed in the panel and have an exposed part. In the example described, these fittings 294 and 295 are formed by sections of angles, one wing of which is embedded in the mass of the panel, and the other wing of which is flush with the surface parallel to it.

On a de même noyé une ferrure dans le panneau de refend 190, de telle manière qu'elle déborde de chaque face latérale de ce panneau, près du chant extérieur de celui-ci et à proximité des ferrures des panneaux de façade. Dans l'exemple décrit, cette ferrure est formé d'une lame dont les deux extrémités sont repliées pour former un U ayant une partie horizontale très allongée. Cette partie horizontale est noyée dans la masse du panneau, et les deux ailes de U affleurent les surfaces latérales du panneau, en étant parallèles à celles-ci.A fitting was likewise embedded in the splitting panel 190, in such a way that it projects beyond each lateral face of this panel, near the outer edge thereof and near the fittings of the front panels. In the example described, this fitting is formed by a blade whose two ends are folded back to form a U having a very elongated horizontal part. This horizontal part is embedded in the mass of the panel, and the two wings of U are flush with the side surfaces of the panel, being parallel to these.

Pour solidariser ces trois ferrures, on utilise des ferrures complémentaires 296 et 297, qui forment des jonctions entre la ferrure 192 et respectivement les ferrures 294 et 295. Ces ferrures de jonction sont des lames d'acier qui sont soudées à l'arc sur les ferrures des panneaux.To join these three fittings together, complementary fittings 296 and 297 are used, which form junctions between the fitting 192 and respectively the fittings 294 and 295. These joining fittings are steel blades which are welded with an arc on the panel fittings.

Une telle méthode de soudure indirecte des ferrures entre-elle, pourrait être utilisée pour les jonctions de tête et de pied de panneau, en cas par exemple de difficultés d'accès des électrodes de soudure.Such a method of indirect welding of the fittings therebetween, could be used for the head and foot joints of the panel, in the case for example of difficulties in accessing the welding electrodes.

A l'inverse, on pourrait aussi prévoir dans le panneau 190, que la ferrure 192 soit rectiligne et déborde de chaque côté des faces latérales de ce panneau de refend 190, pour rejoindre les ferrures 294 et 295, sur lesquelles elle serait soudée directement.Conversely, one could also provide in the panel 190, that the fitting 192 is rectilinear and projects on each side of the lateral faces of this splitting panel 190, to join the fittings 294 and 295, on which it would be welded directly.

La jonction par soudure, décrite tout au long de ce texte, n'est qu'un exemple de solidarisation des ferrures entre-elle, et on peut utiliser tout autre procédé équivalent. Cet ainsi que l'on peut par exemple percer de part en part l'ensemble formé par les ferrures 153, 154 et 352, au travers de la cavité 152 dans la figure 8. Pour fixer ces ferrures ensemble, on peut alors faire passer ensuite un boulon à travers les trous ainsi pratiqués et visser ce boulon.The welded joint, described throughout this text, is only one example of joining the fittings together, and any other equivalent process can be used. This so that one can for example drill right through the assembly formed by the fittings 153, 154 and 352, through the cavity 152 in Figure 8. To fix these fittings together, we can then pass then a bolt through the holes thus made and tighten this bolt.

Le procédé ainsi décrit permet un montage très rapide d'immeubles de grande hauteur, à l'aide de panneaux préfabriqués, sans avoir à attendre la prise du ciment entre deux niveaux successifs, et en utilisant un minimum d'étais pour maintenir un panneau de départ.The process thus described allows very rapid assembly of tall buildings, using prefabricated panels, without having to wait for the cement to set between two successive levels, and using a minimum of props to maintain a panel of departure.
