Description
Dispositif d'assemblage bout à bout de pièces métalliques profilées. L'objet de l'invention est un dispositif d'assemblage bout à bout -de pièces métalli ques profilées, telles que fers à simple et dou ble<B>T,</B> en<B>U,</B> cornières, poutrelles à ailes lar ges ou normales, rails à patin.
Les assemblages exécutés couramment au moyen de simples fers plats fixés sur l'âme des poutrelles à assembler peuvent suffire lorsqu'il s'agit uniquement d'assurer la, liai son de deux barres de poutrelles; par contre là où il s'agit de transmettre également les efforts que subissent les poutrelles, ce mode d'assemblage, en raison de sa faible rigidité, ne peut. être appliqué, à moins toutefois de prévoir également une liaison .des ailes.
Ces inconvénients sont évités selon l'in vention grâce au fait que le dispositif com porte au moins une éclisse qui présente au minimum deux parties faisant un angle en tre elles et dont les faces extérieures épou sent au moins de façon générale la disposi tion de celles des faces des pièces métalli ques en regard desquelles elles se trouvent. Le dessin annexé représente, à titre d'exemple, plusieurs formes d'exécution du dispositif.
La fig. 1. est une vue en perspective d'une première forme d'exécution; Les fig. 2 à 9 montrent chacune en coupe transversale une autre forme d'exécution. La première forme d'exécution (fig. 1) sert à assembler deux poutrelles<I>a, b</I> ayant une section transversale en double<B>T,</B> dans laquelle l'âme et les ailes à leur naissance ont à peu près la même épaisseur. Elle com porte dans ce but deux éclisses c, ayant une section en<B>U</B> et présentant par suite trois faces extérieures planes<I>d, e, f</I> faisant des angles entre elles; ces trois faces épousent exactement la disposition :de celles des faces des poutrelles<I>a, b</I> sur lesquelles elles s'ap pliquent.
Les éclisses c sont rivées en g aux poutrelles a, b. On obtient de cette façon un assemblage très rigide susceptible de transmettre d'une poutrelle à l'autre les ef forts que l'une d'elles subit, sans qu'il soit nécessaire de placer des fers plats -d'assem blage sur les faces extérieures -des ailes des poutrelles.
D'après les fig. 2 et 3 les éclisses c épou sent exactement la disposition :des poutrelles telles que a, sauf aux angles où elles présen tent soit -des congés h (fig. 2), soit des pans coupés i (fig. 3); leurs angles présentent des arrondis dont les rayons de courbure sont sensiblement égaux à ceux des arrondis exis tant entre les faces intérieures des poutrelles. Sur la fig. 2, éclisses et poutrelles sont réu nies par des boulons j. Les âmes :des pou trelles ont ici une épaisseur moindre que les parties les plus minces des ailes.
Selon la fig. 4 les éclisses c sont réunies aux poutrelles par soudure en k dans les trous l et en ira aux extrémités latérales des ailes de ces poutrelles.
Les éclisses n de la fig. 5 ont aussi une section en<B>U,</B> mais présentent en outre des rebords o s'appuyant latéralement sur la tranche p -des ailes des poutrelles. De ce fait- leurs âmes q se trouvent à une faible distance des âmes r des poutrelles.
La fi-. 6 montre des éclisses s dont les faces extérieures épousent assez exactement la disposition des faces correspondantes des poutrelles<I>a,</I> mais dont les ailes t présentent toutefois une inclinaison un peu plus forte que les ailes 2a -de ces poutrelles. Lors de l'assemblage, elles sont donc forcées entre les ailes u, ce qui augmente encore la rigi dité de l'assemblage.
D'après la fig. 7 il s'agit d'assembler deux fers v en<B>U,</B> ce qui a lieu au moyen d'une éclisse 2o en<B>U</B> épousant fort exacte ment la disposition des faces intérieures -des poutrelles, tout en présentant cependant des congés h à ses angles. La liaison entre pou trelles et éclisse a lieu au moyen de boulons j réunissant deux à deux les âmes, d'une part, les ailes, d'autre part.
Selon la fig. 8 les poutrelles x à assem bler ont une section en<B>T</B> renversé. Il y a deux éclisses y qui ont la forme de cornières et dont les faces extérieures épousent exac- tement la disposition des faces intérieures des ailes et les faces -des âmes des poutrelles.
Enfin, la fig. 9 représente l'assemblage de deux cornières z au moyen d'une éclisse 9 épousant extactement la disposition des faces intérieures des cornières.
Les éclisses peuvent être faites de fers plats enboutis ou être laminées au profil voulu; elles peuvent être obtenues soit en barres profilées :de longueur normale, plus grande que la leur, soit en pièces ayant leur longueur.
End-to-end assembly device for profiled metal parts. The object of the invention is a device for butt-joining profiled metal parts, such as single and double <B> T, </B> <B> U, </B> irons. angles, beams with wide or normal flanges, shoe rails.
The assemblies commonly executed by means of simple flat bars fixed to the web of the joists to be assembled may be sufficient when it is only a question of ensuring the, liai sound of two joist bars; on the other hand where it is a question of also transmitting the forces to which the beams are subjected, this method of assembly, because of its low rigidity, cannot. be applied, unless however also providing a connection .des wings.
These drawbacks are avoided according to the invention thanks to the fact that the device comprises at least one fishplate which has at least two parts forming an angle between them and the outer faces of which at least generally match the arrangement of those. of the faces of the metal parts opposite which they are located. The accompanying drawing shows, by way of example, several embodiments of the device.
Fig. 1. is a perspective view of a first embodiment; Figs. 2 to 9 each show in cross section another embodiment. The first embodiment (fig. 1) is used to assemble two beams <I> a, b </I> having a double cross section <B> T, </B> in which the web and the flanges to their births have about the same thickness. It comprises for this purpose two ribs c, having a section in <B> U </B> and consequently having three plane outer faces <I> d, e, f </I> forming angles between them; these three faces exactly match the arrangement: those of the faces of the beams <I> a, b </I> on which they are applied.
The fishplates c are riveted at g to the joists a, b. In this way, a very rigid assembly is obtained capable of transmitting from one joist to another the stresses that one of them undergoes, without it being necessary to place flat connecting bars on the beams. exterior faces of the beams of the joists.
According to fig. 2 and 3 the ribs c marry exactly the arrangement: joists such as a, except at the angles where they present either - leaves h (fig. 2), or cut sides i (fig. 3); their angles have rounded shapes whose radii of curvature are substantially equal to those of the rounded edges existing between the internal faces of the beams. In fig. 2, fishplates and joists are joined by bolts j. Souls: dustbins here are thinner than the thinnest parts of the wings.
According to fig. 4 the fishplates c are joined to the joists by welding in k in the holes l and will go to the lateral ends of the flanges of these joists.
The ribs n in fig. 5 also have a <B> U, </B> section but also have flanges o resting laterally on the edge p-of the flanges of the joists. Therefore their cores q are at a short distance from the webs r of the joists.
The fi-. 6 shows fish plates s whose outer faces quite exactly match the arrangement of the corresponding faces of the joists <I> a, </I> but whose flanges t nevertheless have a slightly greater inclination than the flanges 2a of these joists. During assembly, they are therefore forced between the wings u, which further increases the rigidity of the assembly.
According to fig. 7 it is a question of assembling two irons v in <B> U, </B> which takes place by means of a 2o splice in <B> U </B> matching very exactly the arrangement of the internal faces - joists, while however having fillets h at its angles. The connection between trellis and fishplate takes place by means of bolts joining two by two the webs, on the one hand, and the wings, on the other hand.
According to fig. 8 x joists to be assembled have an inverted <B> T </B> section. There are two fishplates y which have the form of angles and whose outer faces exactly match the arrangement of the inner faces of the wings and the faces of the webs of the joists.
Finally, fig. 9 shows the assembly of two angles z by means of a joint 9 exactly matching the arrangement of the internal faces of the angles.
The ribs can be made of butted flat bars or be rolled to the desired profile; they can be obtained either in profiled bars: of normal length, greater than theirs, or in parts having their length.
