Definitions
- the present invention relates to an anchor connector for a concrete slab on a metal support, such as a steel profile of a metal frame, comprising a base, arranged to be pressed and fixed to the support, and a metal rod, fixed to the base and extending perpendicular to the base to serve as a reinforcement for the concrete slab.
- a metal support such as a steel profile of a metal frame
- connectors of this type aim to oppose a net relative slippage of the slab and the support but allowing tiny amounts displacements when the entire composite structure is loaded, everything preserving the resistance of the connectors.
- these connectors and a concrete slab being "hooked" to a plurality thereof should be with good ductility and support with a harmonious distribution between them the load forces, mainly shear and tearing.
- EP-A-0 504 500 we know a connector comprising a base and a rod riveted in a central opening of the base. Connectors of this type, to rod fixed to the base, allow a harmonious distribution of the charge. However, the rods of these connectors are subjected to efforts important and may therefore break. Such connectors do not have a satisfactory ductility.
- the invention therefore relates to an anchoring connector for a concrete slab on a support metallic, said connector comprising a base, arranged to be plated and fixed to the support, and a metal rod, fixed to the base and extending perpendicular to the base to serve as a reinforcement for the concrete slab, characterized in that the rod is rigidly articulated to the base by at less a hinge gusset arranged to deform and extend the base perpendicular to it and fixed to the rod near an edge of the gusset away from the base and it is welded to it by its foot.
- the rod is thus fixed to the base by two upper and lower zones separated from each other and transmitting its forces to the base by the gusset deformable joint. Thanks to this, the rod can bend and deform, which avoids any abutment effect detrimental to the good performance of the concrete slab.
- the base is designed to be fixed to the support along a line outside of which is the lower area for fixing the rod to the base.
- the articulation gusset is fixed to the rod by welding.
- the rod is articulated to the base of the connector by two substantially trapezoidal gussets extending the base by their large bases and welded to the rod in the areas of the ends opposite the base on their sides extending along the stem.
- the base and the gusset are formed by folding a sheet blank.
- the base is extended by stiffeners, a frontal stiffener and a lateral stiffener extending laterally the gusset of articulation.
- the rod has an enlarged section head arranged to transmit the tearing forces of the support slab to the base.
- the anchoring connector which will now be described comprises a rod cylindrical metal 1, here made of steel, and a base 2
- the base 2 obtained after cutting and folding a sheet blank 3 (FIG. 4), has here an overall shape of an isosceles triangle, with a frontal base 4, a vertex rear 5 opposite the base, two long sides 6, 7 from the top 5 and connected to base 4, not to vertices, but by two short sides 8, 9 perpendicular to the base 4.
- the base 2 is pierced with three holes, one 10, near the top 5, to receive the stem base 11, and the other two 12, 13, the along a line 16 parallel to the base 4, between this base 4 and the vertex 5, to receive fixing pads 14, 15 ( Figure 3).
- the rod 1 is therefore fixed in the lower part to the base 2 in a area thereof spaced from line 16 of its attachment to the support.
- Base 2 is extended, beyond its two long sides 6, 7, by two trapezoids rectangles 17, 18 raised, after folding around these long sides, in planes perpendicular to the base.
- trapezoids serve as gussets of articulation.
- the small bases 19, 20 of the trapezoidal gussets are connected to the large bases 6, 7 by sides 21, 22 extending the short sides 8, 9 of the base 2, on the one hand, and by sides 23, 24 substantially perpendicular to the base-sides 6, 7, on the other hand. After having raised the trapezoidal portions 17, 18 of the blank 3, the sides 23, 24 are practically adjacent.
- Base 2 is also extended beyond its base 4 and its two short sides 8, 9, by three rectangular portions 25, 26, 27 raised, after folding around these bases and short sides, in planes perpendicular to the base. These rectangles serve as front and side stiffeners.
- the lateral stiffeners 26, 27 also extend laterally and substantially at right angles to the trapezoidal gussets 17, 18 which, respectively two by two, are practically adjacent.
- the rod 1 at the end opposite to its foot 11, has a section head 28 enlarged.
- the rod 1 is slightly fitted into the base 2 by its foot 11 and the base hole 10, to extend perpendicular to the base and is there fixed, in this lower zone, by an inner weld 29.
- the rod 1 is also attached to the articulation gussets 17, 18, in an upper zone, by another weld, outside, 30.
- This weld 30 is produced in the zone of the ends, opposite to the base 2, of the sides 23, 24 of the gussets articulation 17, 18, which extend along the rod 1. It can also be said that the rod is fixed to the gussets 17, 18 near their edges 19, 20 distant from base 2.
- the rod 1 is rigidly articulated to the base 2 via the gussets 17, 18 and the two zones 29, 30 separated from one another, for fixing from the rod 1 to the gussets 17, 18 and to the base 2. It is by these gussets deformable articulation 17, 18 that the rod 1 transmits its forces to the base.
- a plurality of connectors are used for anchoring a concrete slab 31 on a metal support 32 of the profiled type in steel with a metal frame, with or without tray 33 in ribbed sheet like the one shown in figure 8.
- the support 32 here comprises an upper sole 34 on which are fixed the connector bases 2.
- Each connector is therefore fixed to the support by two buffers 14, 15 passed through the base holes 12, 13 and sealed in the support using a cartridge sealing tool of the type gun.
- Figure 5 illustrates the effect of a load on the rod 1 directed forward perpendicularly to the line 16 for fixing the base 2 on the support, with bending deformation of the two articulation gussets 17, 18.
- the load is directed backwards perpendicular to the fixing line 16. In this case, the gussets 17, 18 are not deformed.
- the load is directed parallel to the fixing line 16. In this case, the rod 1 being offset relative to this line, the gusset upstream articulation 17, subjected to traction, is not deformed, but the downstream gusset 18, subjected to compression, the east, by buckling.
- the front and side stiffeners not only stiffen the base 2 in bending but contribute to increasing the sections of the critical zones at the shear.
Abstract
Description
La présente invention concerne un connecteur d'ancrage d'une dalle en béton sur un support métallique, tel un profilé en acier d'une charpente métallique, comprenant une embase, agencée pour être plaquée et fixée au support, et une tige métallique, fixée à l'embase et s'étendant perpendiculairement à l'embase pour servir d'armature à la dalle en béton.The present invention relates to an anchor connector for a concrete slab on a metal support, such as a steel profile of a metal frame, comprising a base, arranged to be pressed and fixed to the support, and a metal rod, fixed to the base and extending perpendicular to the base to serve as a reinforcement for the concrete slab.
On connait déjà des connecteurs de ce type. Ils visent à s'opposer à un net glissement relatif de la dalle et du support mais en autorisant d'infimes déplacements lorsque l'ensemble de la structure composite est en charge, tout en préservant la résistance des connecteurs. En un mot, ces connecteurs et une dalle en béton étant "accrochée" à une pluralité de ceux-ci, devraient être dotés d'une bonne ductilité et supporter avec une répartition harmonieuse entre eux les efforts de la charge, principalement de cisaillement et d'arrachement.We already know connectors of this type. They aim to oppose a net relative slippage of the slab and the support but allowing tiny amounts displacements when the entire composite structure is loaded, everything preserving the resistance of the connectors. In a nutshell, these connectors and a concrete slab being "hooked" to a plurality thereof, should be with good ductility and support with a harmonious distribution between them the load forces, mainly shear and tearing.
Par FR-A-2 317 438, on connaít un connecteur de type cornière comportant une patte d'appui, formant embase, prolongée par une branche d'ancrage, le tout d'une seule pièce. La branche d'ancrage de ce connecteur ne peut pas bien fléchir et se déformer dans toutes les directions. Il en résulte qu'une pluralité de tels connecteurs ne se répartissent pas harmonieusement entre eux les efforts de charge.By FR-A-2 317 438, there is known an angle type connector comprising a support leg, forming a base, extended by an anchoring branch, the whole in one piece. The anchor branch of this connector cannot flex and deform in all directions. As a result, a plurality of such connectors do not distribute the forces harmoniously between them dump.
Par EP-A-0 504 500, on connaít un connecteur comportant une embase et une tige rivetée dans une ouverture centrale de l'embase. Les connecteurs de ce type, à tige fixée à l'embase, permettent une répartition harmonieuse des efforts de charge. Toutefois, les tiges de ces connecteurs sont soumis à des efforts importants et risquent par conséquent de se rompre. De tels connecteurs ne présentent dont par une ductilité satisfaisante.By EP-A-0 504 500, we know a connector comprising a base and a rod riveted in a central opening of the base. Connectors of this type, to rod fixed to the base, allow a harmonious distribution of the charge. However, the rods of these connectors are subjected to efforts important and may therefore break. Such connectors do not have a satisfactory ductility.
Les connecteurs du commerce ne donnent donc pas entière satisfaction et l'inventeur s'est attaché à en inventer un dont la ductilité soit très bonne.Commercial connectors are therefore not entirely satisfactory and the inventor set out to invent one whose ductility is very good.
L'invention concerne donc un connecteur d'ancrage d'une dalle en béton sur un support métallique, ledit connecteur comprenant une embase, agencée pour être plaquée et fixée au support, et une tige métallique, fixée à l'embase et s'étendant perpendiculairement à l'embase pour servir d'armature à la dalle en béton, caractérisé par le fait que la tige est articulée rigidement à l'embase par au moins un gousset d'articulation agencé pour se déformer et prolongeant l'embase perpendiculairement à elle et fixé à la tige près d'un bord du gousset éloigné de l'embase et elle y est soudée par son pied.The invention therefore relates to an anchoring connector for a concrete slab on a support metallic, said connector comprising a base, arranged to be plated and fixed to the support, and a metal rod, fixed to the base and extending perpendicular to the base to serve as a reinforcement for the concrete slab, characterized in that the rod is rigidly articulated to the base by at less a hinge gusset arranged to deform and extend the base perpendicular to it and fixed to the rod near an edge of the gusset away from the base and it is welded to it by its foot.
La tige est ainsi fixée à l'embase par deux zones supérieure et inférieure écartées l'une de l'autre et transmettant ses efforts à l'embase par le gousset d'articulation déformable. Grâce à cela, la tige peut fléchir et se déformer, ce qui évite tout effet de butée préjudiciable à la bonne tenue de la dalle de béton.The rod is thus fixed to the base by two upper and lower zones separated from each other and transmitting its forces to the base by the gusset deformable joint. Thanks to this, the rod can bend and deform, which avoids any abutment effect detrimental to the good performance of the concrete slab.
Avantageusement, l'embase est agencée pour être fixée au support le long d'une ligne hors de laquelle se trouve la zone inférieure de fixation de la tige à l'embase. Advantageously, the base is designed to be fixed to the support along a line outside of which is the lower area for fixing the rod to the base.
De préférence, le gousset d'articulation est fixé à la tige par soudure.Preferably, the articulation gusset is fixed to the rod by welding.
De préférence encore, la tige est articulée à l'embase du connecteur par deux goussets sensiblement trapézoïdaux prolongeant l'embase par leurs grandes bases et soudés à la tige dans les zones des extrémités opposées à l'embase de leurs cotés s'étendant le long de la tige.More preferably, the rod is articulated to the base of the connector by two substantially trapezoidal gussets extending the base by their large bases and welded to the rod in the areas of the ends opposite the base on their sides extending along the stem.
De préférence toujours, l'embase et le gousset sont formés par pliage d'un flan de tôle.Still preferably, the base and the gusset are formed by folding a sheet blank.
Avantageusement aussi, l'embase est prolongée par des raidisseurs, un raidisseur frontal et un raidisseur latéral prolongeant latéralement le gousset d'articulation.Advantageously also, the base is extended by stiffeners, a frontal stiffener and a lateral stiffener extending laterally the gusset of articulation.
Avantageusement encore, la tige possède une tête de section élargie agencée pour transmettre à l'embase les efforts d'arrachement de la dalle du support.Advantageously also, the rod has an enlarged section head arranged to transmit the tearing forces of the support slab to the base.

Le connecteur d'ancrage qui va maintenant être décrit comporte une tige
cylindrique métallique 1, ici en acier, et une embase 2The anchoring connector which will now be described comprises a rod
L'embase 2, obtenue après découpe et pliage d'un flan de tôle 3 (figure 4), a ici
une forme globale de triangle isocèle, avec une base frontale 4, un sommet
arrière 5 opposé à la base, deux grands côtés 6, 7 issus du sommet 5 et
raccordés à la base 4, non pas à des sommets, mais par deux petits côtés 8, 9
perpendiculaires à la base 4. L'embase 2 est percée de trois trous, l'un 10,
près du sommet 5, pour recevoir le pied de tige 11, et les deux autres 12, 13, le
long d'une ligne 16 parallèle à la base 4, entre cette base 4 et le sommet 5,
pour recevoir des tampons de fixation 14, 15 (figure 3). On notera d'ores et
déjà ici que la tige 1 est donc fixée en partie inférieure à l'embase 2 dans une
zone de celle-ci écartée de la ligne 16 de sa fixation au support. L'embase 2
est prolongée, au-delà de ses deux grands côtés 6, 7, par deux trapèzes
rectangles 17, 18 relevés, après pliage autour de ces grands côtés, dans des
plans perpendiculaires à l'embase. Ces trapèzes servent de goussets
d'articulation. Avant pliage, les petites bases 19, 20 des goussets trapézoïdaux
sont raccordés aux grandes bases 6, 7 par des côtés 21, 22 prolongeant les
petits côtés 8, 9 de l'embase 2, d'une part, et par des côtés 23, 24
sensiblement perpendiculaires aux côtés-bases 6, 7, d'autre part. Après avoir
relevé les portions trapézoïdales 17, 18 du flan 3, les côtés 23, 24 sont
pratiquemernt adjacents.The
L'embase 2 est également prolongée au-delà de sa base 4 et de ses deux
petits côtés 8, 9, par trois portions rectangulaires 25, 26, 27 relevées, après
pliage autour de ces base et petits côtés, dans des plans perpendiculaires à
l'embase. Ces rectangles servent de raidisseurs frontal et latéraux.
Après avoir relevé les portions trapézoïdales 17, 18 et rectangulaires 26, 27 du
flan 3, les raidisseurs latéraux 26, 27 prolongent aussi latéralement et
sensiblement à angle droit les goussets trapézoïdaux 17, 18 qui,
respectivement deux à deux, sont pratiquement adjacents.After having noted the
La tige 1, à l'extrémité opposée à son pied 11, possède une tête 28 de section
élargie. The
La tige 1 est légèrement emmanchée dans l'embase 2 par son pied 11 et le
trou d'embase 10, pour s'étendre perpendiculairement à l'embase et elle y est
fixée, dans cette zône inférieure, par une soudure intérieure 29. La tige 1 est
également fixée aux goussets d'articulation 17, 18, dans une zone supérieure,
par une autre soudure, extétieure, 30. Cette soudure 30 est réalisée dans la
zone des extrémités, opposées à l'embase 2, des côtés 23, 24 des goussets
d'articulation 17, 18, qui s'étendent le long de la tige 1. On peut aussi dire que
la tige est fixée aux goussets 17, 18 près de leurs bords 19, 20 éloignés de
l'embase 2.The
Ainsi, la tige 1 est articulée rigidement à l'embase 2 par l'intermédiaire des
goussets 17, 18 et des deux zones 29, 30 écartées l'une de l'autre, de fixation
de la tige 1 aux goussets 17, 18 et à l'embase 2. C'est par ces goussets
d'articulation déformables 17, 18 que la tige 1 transmet ses efforts à l'embase.Thus, the
Une pluralité de connecteurs, comme celui qui vient d'être décrit, sont utilisés
pour ancrer une dalle de béton 31 sur un support métallique 32 du type profilé
en acier d'une charpente métallique, avec ou sans bac 33 en tôle nervurée
comme celui représenté sur la figure 8. Toujours comme représenté sur cette
figure, le support 32 comporte ici une semelle supérieure 34 sur laquelle sont
fixées les embases de connecteurs 2. Chaque connecteur est donc fixé au
support par deux tampons 14, 15 passés à travers les trous d'embase 12, 13 et
scellés dans le support à l'aide d'un outil de scellement à cartouches du type
pistolet.A plurality of connectors, like the one just described, are used
for anchoring a
En référence aux figures 5-7, la figure 5 illustre l'effet d'une charge sur la tige 1
dirigée vers l'avant perpendiculairement à la ligne 16 de fixation de l'embase 2
sur le support, avec déformation par cintrage des deux goussets d'articulation
17, 18. Sur la figure 6, la charge est dirigée vers l'arrière perpendiculairement à
la ligne de fixation 16. Dans ce cas, les goussets 17, 18 ne sont pas déformés.
Sur la figure 7, la charge est dirigée parallèlement à la ligne de fixation 16.
Dans ce cas, la tige 1 étant déportée par rapport à cette ligne, le gousset
d'articulation amont 17, soumis à une traction, n'est pas déformé, mais le
gousset aval 18, soumis à une compression, l'est, par flambage. Referring to Figures 5-7, Figure 5 illustrates the effect of a load on the
De façon générale, l'ensemble des déformations de la tige et de l'embase
permet un léger glissement relatif de la dalle 31 et du support 32 avec un
excellent niveau de ductilité.In general, all the deformations of the rod and the base
allows a slight relative sliding of the
Les raidisseurs frontal et latéraux non seulement rigidifient l'embase 2 en
flexion mais contribuent à augmenter les sections des zones critiques au
