Ces conduits ou joints techniques ont par exemple pour fonction de permettre la mise en place de tuyaux qui assureront l'ecoulement des eaux usees, etc. De maniere traditionnelle, lorsque l'on realise le coffrage du plancher a mettre en place, on positionne dans le (ou les) endroit(s) voulu(s) une piece en bois formant reservation. On procede alors au courage du beton puts, lorsque celui ci a opere sa prise, on enleve la reservation en bois. Le trou ainsi degage peut etre These technical conduits or seals have the function, for example, of allowing the installation of pipes which will ensure the flow of used water, etc. Traditionally, when the formwork for the floor to be put in place is placed in the (or the) place (s) desired (s) a wooden piece forming a reservation. We then proceed to the courage of the put concrete, when it has set, we remove the wooden reservation. The hole thus cleared can be

conduits ou de gaines.conduits or sheaths.
Le procede de percage selon ['invention est realise au moyen d'un The drilling method according to the invention is carried out by means of a
outil tel que celui visible aux figures 3 et 4 notamment. tool such as that visible in Figures 3 and 4 in particular.
Cet outil 1 est par exemple realise en acier trempe, du type de celui This tool 1 is for example made of hardened steel, of the type of that
utilise pour la fabrication de buries. used for the manufacture of buries.
I1 comprend essentiellement une tige longitudinale l'axe X-X' qui, dans l'exemple represente ici, a une section hexagonale. Sa plus grande dimension I1 essentially comprises a longitudinal rod the axis XX ′ which, in the example shown here, has a hexagonal section. Its greatest dimension
transversale est de l'ordre de 20 millimetres. transverse is of the order of 20 millimeters.
A une extremite, cette tige presente un alesage 12, parfaitement cylindrique, autorisant sa mise en place sur le mandrin d'une perceuse portative du commerce. A l'extremite opposee, la tige 10 se pour-quit par une pointe 11 qui At one end, this rod has a bore 12, perfectly cylindrical, allowing it to be placed on the mandrel of a portable commercial drill. At the opposite end, the rod 10 is quit by a point 11 which
forme, comme on le verra plus loin, une pointe de centrage. forms, as will be seen below, a centering point.
En partie basse, ctest-a-dire au voisinage de la partie superieure de la pointe 11, la tige porte une padre de palettes 2 et 3 qui s'etendent sensiblement dans le prolongement l'un de 1'autre. Toutefois, dans l'exemple represente, elles vent In the lower part, that is to say in the vicinity of the upper part of the tip 11, the rod carries a pad of pallets 2 and 3 which extend substantially in the extension of one another. However, in the example shown, they wind
decalees de quelques millimetres de part et d'autre de l'axe X-X'. shifted by a few millimeters on either side of the axis XX '.
La largeur totale d des deux palettes 2 et 3 et de la tige 10 est egale au diametre de l'ouverture a percer. De preference, ce diametre est compris entre 60 The total width d of the two pallets 2 and 3 and of the rod 10 is equal to the diameter of the opening to be drilled. Preferably, this diameter is between 60
et 250 millimetres.and 250 millimeters.
En se reportant a la figure 4, on constate que les palettes 2 et 3 vent formees chacune d'une partie superieure 20, respectivement 30, qui s'etend longitudinalement, parallelement a l'axe X-X', et d'une - partie inferieure 21, respectivement 31, qui forme un angle obtus par rapport a la partie superieure Referring to FIG. 4, it can be seen that the pallets 2 and 3 are each formed of an upper part 20, respectively 30, which extends longitudinally, parallel to the axis XX ', and of a - lower part 21, respectively 31, which forms an obtuse angle with respect to the upper part
correspondante. Cet angle a est de preference compris entre 150 et 160 . corresponding. This angle a is preferably between 150 and 160.
Ainsi que le montre aussi la figure 4, les parties inferieures 21 et 31 des deux palettes 2 et 3 s'etendent selon des directions opposees l'une a l'autre, de As also shown in FIG. 4, the lower parts 21 and 31 of the two pallets 2 and 3 extend in opposite directions to one another, from
sorte que, vues de cote, elles forment en quelque sorte un "X". so that, seen from the side, they sort of form an "X".
Dans le cas represente ici, les parties superieure et inferieure de chaque palette constituent une senle et meme piece. Toutefois, dans un mode de realisation different, il pourrait s'agir de deux pieces fixees l'une a l'autre, In the case represented here, the upper and lower parts of each pallet constitute a single part and the same part. However, in a different embodiment, it could be two pieces fixed to each other,
notamment par soudage.especially by welding.
On a reference 22, respectivement 32, les aretes coupantes qui We have reference 22, respectively 32, the cutting edges which
stetendent en partie inferieure des palettes, perpendiculairement a l'axe X-X'. stetendent in the lower part of the pallets, perpendicular to the axis XX '.
L'arete 22 de la palette 2 est dblimitee par une face 220 de la partie The edge 22 of the pallet 2 is delimited by a face 220 of the part
22 et un pan coupe 222 de sa seconde face 221. 22 and a cross section 222 of its second face 221.
Il en est de mCme de l'arEte 32 de la palette 3, dblimitb par une face The same is true of edge 32 of palette 3, defined by one face
310 et le pan coupb 312 de sa seconde face 311. 310 and the pan coupb 312 of its second face 311.
Les deux diedres qui dblimitent les arOtes 22 et 32 vent done orientes The two mortres which delimit arOtes 22 and 32 are therefore oriented
selon des directions opposees, de part et d'autre de l'axe longitudinal XX'. in opposite directions, on either side of the longitudinal axis XX '.
Cette orientation particuliere des ar8tes, combinee au fait que les parties inferieures 21 et 31 des palettes soient orientbes en biais, va contribuer, comme on le verra plus loin, a faciliter ltevacuation de la matiere This particular orientation of the edges, combined with the fact that the lower parts 21 and 31 of the pallets are oriented at an angle, will contribute, as will be seen below, to facilitate the evacuation of the material.

De prEfirence, des renforts (non representes sur les figures) vent utilists pour fixer les palettes a la tige 1, ceci afin de pouvoir rbsister au couple qui Preferably, reinforcements (not shown in the figures) are used to fix the pallets to the rod 1, in order to be able to resist the torque which
s'applique sur les palettes en rotation, du fait de leur grande largeur. applies to rotating pallets, due to their large width.
s En se referent aux figures 5 a 7, nous allons maintenant expliquer s Referring to Figures 5 to 7, we will now explain
comment on met en ccuvre le procede selon ['invention. how the process according to the invention is implemented.
La tige ayant ete prealablement montee a l'extremite du mandrin d'une perccuse portative, on positionne l'outil de maniere a ce que sa pointe 11 s'appuie a la surface de la reservation R a percer. Dans cette position (voir figure 5), les arCtes 22 et 32 de 1'outil s'etendent parallelement a la surface superieure de la The rod having been previously mounted at the end of the mandrel of a portable perccuse, the tool is positioned so that its tip 11 rests on the surface of the reservation R to be drilled. In this position (see Figure 5), the edges 22 and 32 of the tool extend parallel to the upper surface of the
reservation et a distance de celle-ci. reservation and at a distance from it.
On actionne alors la perceuse portative, de facon a ce que la tige 10 We then operate the portable drill, so that the rod 10
soit animee d'un mouvement de rotation f autour de l'axe X-X'. be driven by a rotational movement f around the axis XX '.
A titre indicatif, on peut utiliser une perceuse portative d'une puissance de 650 Watts, entranant la tige 10 a une vitesse de l'ordre 500 tours par minute. Le mouvement de rotation de l'outil, combine a l'enfoncement de l'outil dans le sens de la fleche g fait que les arOtes coupantes 22 et 32 attaquent la matiere tendre de la reservation, de facon a y former une ouverture. L'orientation particuliere des palettes 2 et 3 et, notamment de leurs parties inferieures respectives 21 et 31, contribue a faciliter ltevacuation vers ltexterieur de la matiere desagregee par ltoutil, comme le montre les fleches h. Enfin, le mouvement de percage est poursuivi, comme le montre la figure 7, jusqu'a l'obtention d'une ouverture cylindrique O qui fait communiquer As an indication, one can use a portable drill with a power of 650 Watts, driving the rod 10 at a speed of the order of 500 revolutions per minute. The rotational movement of the tool, combined with the insertion of the tool in the direction of the arrow g causes the cutting edges 22 and 32 to attack the tender material of the reservation, so as to form an opening therein. The particular orientation of the pallets 2 and 3 and, in particular of their respective lower parts 21 and 31, contributes to facilitating the evacuation towards the outside of the material disaggregated by the tool, as shown by the arrows h. Finally, the drilling movement is continued, as shown in FIG. 7, until a cylindrical opening O is obtained which causes communication
les faces superieure et inferieure de la reservation l'une avec l'autre. the upper and lower sides of the reservation with each other.
