Description
-1- On a souvent besoin d'assembler des poutrelles,en génie civil ou-1- We often need to assemble joists, in civil engineering or
batiment.Généralement les deux poutrelles à assembler sont posées l'une sur l'autre et perpendiculaires entre elles.C'est le cas par exemple dans les tables de coffrage ou les coffrages de dalles traditionnels ou les banches:il y a un premier lit de poutrelles (longerons ou raidisseurs) et un deuxième lit de Generally, the two beams to be joined are placed one on top of the other and perpendicular to each other. This is the case, for example, in formwork tables or traditional slab formwork or formwork: there is a first bed beams (beams or stiffeners) and a second bed
poutrelles sur lesquelles prend appui la peau de coffrage. beams on which the formwork skin is supported.
On comnnait différents moyens d'assembler entre elles deux We knew different ways of joining together two
poutrelles orthogonales:Généralement les poutrelles sont des profi- orthogonal beams: Generally the beams are profi-
lés en I (poutrelles métalliques ou poutrelles bois ou poutrelles mixtes (métal + bois ou matériau de remplacement).On peut,par exemple les assembler à l'aide de crapauds maintenus par des étriers ou les boulonner l'une sur l'autre en perçant des trous dans les ailes (ce qui n'est pas toujours possible) ou percer des trous dans I-strips (metal beams or wooden beams or mixed beams (metal + wood or replacement material). We can, for example, assemble them using toads held by stirrups or bolt them together drilling holes in the wings (which is not always possible) or drilling holes in
les ailes d'une seule poutrelle pour y passer des boulons mainte- the wings of a single beam to pass bolts now-
nant des crapauds.Ces solutions sont lentes à mettre en oeuvre et elles sont onéreuses.De plus,percer des trous dans les ailes des These solutions are slow to implement and expensive, and drill holes in the wings of the toads.
poutrelles est une détérioration qui nuit à leur réemploi. joists is a deterioration that hinders their reuse.
La présente invention permet d'éviter ces inconvénients. The present invention avoids these drawbacks.
Elle permet d'assembler deux poutrelles possédant des ailes,même de petites dimensions,sans percer de trous et sans avoir d'écrous à It allows to assemble two beams having wings, even of small dimensions, without drilling holes and without having nuts to
serrer.C'est de plus une solution économique et rapide. It is also an economical and quick solution.

ment accidentel.accidentally.
On voit sur la figure i les deux poutrelles 1 et 2 qui sont assemblées par deux agrafes 3 situées de part et d'autre de la poutrelle 1. Chaque agrafe comporte un ou plusieurs crochets 4 qui We see in Figure i the two beams 1 and 2 which are assembled by two clips 3 located on either side of the beam 1. Each clip has one or more hooks 4 which

porte également un talon 6 qui enveloppe l'aile 7 de la poutrelle 2. also carries a heel 6 which envelops the wing 7 of the beam 2.
A l'opposé du talon 6,chaque agrafe comporte une languette 8 munie d'un ergot 9 quipar élasticité,vient se loger sous l'aile 7 de la poutrelle 2.L'agrafe est réalisée en un matériau à haute limite Opposite the heel 6, each clip has a tongue 8 provided with a lug 9 which is elastic, comes to be housed under the wing 7 of the beam 2. The clip is made of a material with a high limit
élastique,comme,par exemple,un feuillard d'acier à ressort trempé. elastic, such as, for example, a hardened spring steel strip.
La mise en place du dispositif se fait de la façon suivante: Les deux poutrelles 1 et 2 ayant été placées dans leur position The installation of the device is done as follows: The two beams 1 and 2 having been placed in their position
définitive,on met en place une première agrafe 3 contre la poutrel- final, we put in place a first clip 3 against the beam-
le 1 en glissant son talon 6 sous l'aile 7 de la poutrelle 2.Puis on la fait pivoter autour de son talon 6 en la pressant vers le bas 1 by sliding its heel 6 under the wing 7 of the beam 2.Then we rotate it around its heel 6 by pressing it down
avec un effort suffisant pour que son ergot 9 s'engage par élasti- with sufficient effort so that its lug 9 engages by elastic-
cité sous l'aile 7 de la poutrelle 2.Les crochets 4 enveloppent cited under wing 7 of the beam 2. Hooks 4 wrap around
alors parfaitement 1 ' aile 5 de la poutrelle 1. then perfectly the wing 5 of the beam 1.
On procède de même avec une deuxième agrafe pour fixer l'autre aile inférieure de la poutrelle I.Cette dernière est alors prisonnière entre les deux agrafes qui maintiennent fermement ses deux ailes inférieures. Pour démonter l'assemblegeon procède de la manière inverse: On soulève la languette 8 à la main ou à l'aide d'un tourne-vis ou de tout autre levier pour faire échapper l'ergot 9,ce qui libère We proceed in the same way with a second clip to fix the other lower wing of the beam I. This latter is then trapped between the two clips which firmly hold its two lower wings. To disassemble the assembly proceed in the opposite way: We lift the tongue 8 by hand or using a screwdriver or any other lever to make the pin 9 escape, which releases
l'agrafe 3.clip 3.
Pour que l'ergot 9 ait une résistance suffisante,il est souhai- In order for lug 9 to have sufficient strength, it is desirable to
table que ce ne soit pas une simple languette découpée et pliée, mais un "crevé" obtenu par découpage-emboutissagede façon que les -3- c8tés 11 de l'ergot 9 restent rattachés à la languette 8,seule la partie supérieure du"crevé"étant ouverte.Un "crevé" cylindrique, table that it is not a simple cut and folded tongue, but a "punctured" obtained by cutting-stamping so that the -3- c8tés 11 of the lug 9 remain attached to the tongue 8, only the upper part of the "punctured "being open. A cylindrical" punctured ",
comme représenté sur la figure 4 permet d'obtenir ce résultat. as shown in Figure 4 provides this result.
Les poutrelles comportent des tolérances de fabrication, de sorte que,d'une poutrelle à l'autre, il peut y avoir de petites différences d'épaisseur des ailes.De même,d'une agrafe à l'autre, il peut y avoir de petites différences de cotes.On sera donc obligé de prévoir la fabrication pour que toutes les agrafes puissent se The beams have manufacturing tolerances, so that from one beam to another there may be small differences in wing thickness, and from one clip to another there may be small differences in dimensions, so we will have to plan the manufacturing so that all staples can be
monter sur les poutrelles dont les ailes sont les plus épaisses. climb on the beams with the thickest wings.
Mais alorsdans le cas des ailes les plus minces,on aura un jeu, d'o un risque de glissement des agrafes pouvant conduire les ailes à s'échapper des crochets.Pour éviter ce risque,il sera bon de donner à l'agrafe une forme telle que,par élasticité,elle reste toujours en contact énergique avec les deux poutrelles.On pourra par exemple leur donner la forme représentée sur la figure 5: Le talon 6 possède un retour 10 qui s'appuie sous l'aile 7 de la poutrelle 2.0u bien encore,comme représenté sur la figure 6,1e dos de l'agrafe comporte,à l'intérieur,un bossage (qui peut être une nervure obtenue par emboutissage) transversal 12 situé à quelques millimètres du retour 10 en direction de la languettede façon à constituer un levier du premier genre quipar élasticité,applique But then in the case of the thinnest wings, there will be a clearance, hence a risk of slipping of the staples which can lead the wings to escape from the hooks. To avoid this risk, it will be good to give the staple a shape such that, by elasticity, it always remains in energetic contact with the two beams. We could for example give them the shape shown in FIG. 5: The heel 6 has a return 10 which rests under the wing 7 of the beam 2.0 or else again, as shown in FIG. 6.1 on the back of the clip comprises, inside, a transverse boss (which may be a rib obtained by stamping) 12 located a few millimeters from the return 10 towards the tongue so as to constitute a lever of the first kind which by elasticity, applies
énergiquement le retour 10 sous l'aile 7 de la poutrelle 2. energetically the return 10 under the wing 7 of the beam 2.
Le glissement de l'agrafe est ainsi rendu impossible. The sliding of the staple is thus made impossible.
Bien entendusur une m9me agrafe,on peut réunir les deux solutions Of course on the same clip, we can combine the two solutions
et avoir à la fois un retour du talon et un bossage,comme repré- and have both a heel return and a boss, as shown
senté sur la figure 6.felt in figure 6.
Ce genre de dispositif est utilisable pour toutes les pou- This kind of device can be used for all
