Description

OUTIL FOREUR DE POLYSTYRENE SEMI-AUTONOME La présente invention concerne un outil destiné à forer en aveugle, aux fins de passage de conduits électriques, le polystyrène de doublage thermique et/ou phonique des contre-cloisons ou celui des cloisons. Ce procédé trouve son application dans le domaine du bâtiment et ne fragilise pas le parement des matériaux sus-cités : plaque de plâtre ou briquette. The present invention relates to a tool intended for blind drilling, for the purpose of passing electrical conduits, the thermal and / or phonic doubling polystyrene of the against-partitions or that of the partitions. This process finds its application in the building field and does not weaken the facing of the aforementioned materials: plasterboard or briquette.
En l'état actuel de la technique, il est en effet nécessaire, pour procéder à la mise en place de ces gaines, de réaliser au préala- ble une saignée dans la plaque de plâtre et le polystyrène ou la briquette et le polystyrène. D'où : une perte conséquente de temps, des salissures importantes, de bruit, la création de ponts thermiques dans le cas des cloisons de doublage et, pour finir, l'obligation de reboucher au plâtre ou au mortier de ciment, puis de lisser, les saignées ainsi réalisées après pose des conduits.In the current state of the art, it is indeed necessary, in order to install these sheaths, to carry out beforehand a grooving in the plasterboard and the polystyrene or the briquette and the polystyrene. From where: a consequent loss of time, important stains, noise, the creation of thermal bridges in the case of the lining partitions and, finally, the obligation to recap with plaster or cement mortar, then to smooth , the grooves thus produced after laying the conduits.
En solution à la technique actuelle, peu évidente, de la réalisation des saignées, l'outil proposé permet, en une seule opération, le forage cylindrique du polystyrène, afin de permettre le passage des conduits électriques. Cet outil se compose de deux parties :In solution to the current technique, which is not very obvious, for making grooves, the proposed tool allows, in a single operation, the cylindrical drilling of polystyrene, in order to allow the passage of electrical conduits. This tool consists of two parts:
- le foreur,- the driller,
- le support du foreur.- the support of the driller.
Le foreur, destiné à forer le polystyrène, comporte :The driller, intended for drilling polystyrene, comprises:
- une partie métallique destinée à être chauffée, - une résistance électrique destinée à chauffer la partie métallique,- a metal part intended to be heated, - an electrical resistance intended to heat the metal part,
- une partie isolante formant corps, abritant les connexions électriques et assemblée à la partie métallique,- an insulating part forming a body, housing the electrical connections and assembled to the metal part,
- une vis creuse d'assemblage,- a hollow assembly screw,
- des rondelles isolantes, - un câble électrique, repéré étriquement, alimentant [L'outil. Le support du foreur se compose :- insulating washers, - an electric cable, spotted tightly, supplying [The tool. The support of the driller consists of:
- d'un axe recevant :- an axis receiving:
- un 1er bras permettant le maintien horizontal du support,- a 1st arm allowing the horizontal support of the support,
- un 2ème bras assurant le guidage et la mise en pression du galet presseur,- a 2nd arm ensuring the guiding and pressurizing of the pressure roller,
- un 3ème bras articulé permettant l'assise du support sur le parement de la cloison ou de la contre-cloison, - un galet presseur assurant le plaquage du câble d'alimentation dans une gorge de la poulie,- a 3rd articulated arm allowing the support to sit on the facing of the partition or counter-partition, - a pressure roller ensuring the plating of the supply cable in a groove of the pulley,
- une poulie comprenant 2 gorges, l'une destinée à assurer la demande de câble électrique du foreur et l'autre assurant le déroulage d'une câblette et la descente de masses de poids différents.- a pulley comprising 2 grooves, one intended to ensure the demand for the driller's electric cable and the other ensuring the unwinding of a cable and the descent of masses of different weights.
Les dessins annexés illustrent l'invention en 3 figures :The accompanying drawings illustrate the invention in 3 figures:
- La figure 1/3 représente, en coupe, le dispositif du foreur,- Figure 1/3 shows, in section, the driller's device,
- La figure 2/3 représente, vues de côté et en position de travail, les différentes pièces composant le support mural, - La figure 3/3, représente, selon le plan de coupe A.A, ces mêmes pièces.- Figure 2/3 represents, seen from the side and in the working position, the different parts making up the wall support, - Figure 3/3, represents, according to the cutting plane A.A, these same parts.
En référence à ces dessins, le foreur comporte à son extrémité, une partie métallique, de forme cylindro-conique (1) capable, grâce à sa résistance chauffante (11), située en son milieu, de faire fondre le polystyrène.With reference to these drawings, the driller comprises at its end, a metal part, of cylindro-conical shape (1) capable, thanks to its heating resistor (11), located in the middle, of melting the polystyrene.
Le corps isolant (2) permet la prise en main de l'outil grâce à ses empreintes (8) et abrite les connexions électriques (13). Il est assemblé à la partie métallique (1) par la vis creuse (3).The insulating body (2) allows the grip of the tool thanks to its imprints (8) and shelters the electrical connections (13). It is assembled to the metal part (1) by the hollow screw (3).
Le corps isolant (2) comporte un plan de joint plat sur lequel s'articulent, grâce aux charnières plastique (9), deux demi-coquilles. Le corps isolant (2) porte des picots (6) permettant de positionner et de limiter le glissement des conducteurs du câble d'alimentation (12).The insulating body (2) has a flat joint plane on which are articulated, thanks to the plastic hinges (9), two half-shells. The insulating body (2) carries pins (6) making it possible to position and limit the sliding of the conductors of the power cable (12).
En complément des picots { ' 6) , la partie à bossages (7) vient bloquer le câble d'alimentation (12) en le comprimant lorsque les demi- coquilles du corps isolant (2) sont refermées et assemblées, grâce aux clips de fermeture mâle et femelle (10).In addition to the pins { ' 6), the boss part (7) blocks the power cable (12) by compressing it when the half-shells of the insulating body (2) are closed and assembled, thanks to the closing clips. male and female (10).
Deux rondelles isolantes (4) limitent le rayonnement de la chaleur dans le corps isolant (2). Les évents (5) assurent la mise à l'air libre de l'outil et la dissipation de la chaleur.Two insulating washers (4) limit the radiation of heat in the insulating body (2). The vents (5) ensure that the tool is vented and the heat is dissipated.
Une cosse électrique (14) reçoit le conducteur de mise à la terre. Elle est bloquée grâce à la vis creuse (3) et mise en contact avec le corps chauffant (1) par le taraudage qui y est usiné.An electrical terminal (14) receives the grounding conductor. It is blocked by the hollow screw (3) and brought into contact with the heating body (1) by the thread which is machined there.
En référence à ces dessins, le support mural comporte un axe (15) de section carrée, fileté à ses extrémités, dans lequel viendra se loger un bras (16) assurant le maintien vertical de l'ensemble du support.With reference to these drawings, the wall support comprises an axis (15) of square section, threaded at its ends, in which an arm (16) will be housed ensuring the vertical support of the entire support.
Ce bras (16) se compose d'un tube métallique rond, courbé à sa première extrémité de façon à rentrer dans le trou percé préalablement dans la cloison par l'utilisateur. Ce trou est destiné, par la suite, à recevoir les boîtes de cloisons creuses permettant l'encastrement des mécanismes d'appareillage électrique dans les cloisons ou contre-cloisons. A l'autre extrémité du bras (16), le tube sera aplati et poinçonné en forme de carré, de façon à rentrer dans l'axe (15), sans tourner.This arm (16) consists of a round metal tube, curved at its first end so as to enter the previously drilled hole in the partition by the user. This hole is intended, thereafter, to receive the boxes of hollow partitions allowing the embedding of the electrical equipment mechanisms in the partitions or counter-partitions. At the other end of the arm (16), the tube will be flattened and punched in the shape of a square, so as to enter the axis (15), without turning.
Un bras (17) composé de 2 demi-bras articulés, permettra l'assise axiale et horizontale du support. Il sera lui aussi usiné de façon à rentrer dans l'axe (15), sans tourner.An arm (17) composed of 2 articulated half-arms, will allow the axial and horizontal seat of the support. It will also be machined so as to enter the axis (15), without turning.
Une poulie (18) à 2 gorges, recevra dans l'une des gorges une câblette (19) enroulée. Au bout de cette câblette viendront s'accrocher, en phase de travail, différentes masses (20) de lestage.A pulley (18) with 2 grooves, will receive in one of the grooves a coiled cable (19). At the end of this cable will come to hang, during the working phase, different ballast masses (20).
Les différentes masses (20) assureront la rotation de la poulie (18) afin de pousser le câble d'alimentation (12) du foreur dans sa descente dans le polystyrène. Ces différentes masses (20) présentent l'avantage, puisque leur phase de travail débute au même niveau que celle du foreur, d'indiquer à tout moment le niveau de descente aveugle du foreur dans la cloison. Elles indiquent aussi que le forage est achevé lorsque les masses (20) touchent le sol, dans le cas d'un forage vertical.The different masses (20) will rotate the pulley (18) in order to push the supply cable (12) of the driller in its descent into the polystyrene. These different masses (20) have the advantage, since their work phase begins at the same level as that of the driller, to indicate at any time the level of blind descent of the driller into the partition. They also indicate that drilling is completed when the masses (20) touch the ground, in the case of vertical drilling.
Pour forer obliquement, un aimant puissant guidé par la main de l'utilisateur, attirera le foreur dans la direction voulue ; le support mural n'est alors pas nécessaire pour ce cas précis. En forage vertical, l'utilisateur, pour assurer la synchronisation avec le foreur, devra adapter les masses en fonction de la hauteur du forage.To drill obliquely, a strong magnet guided by the user's hand will draw the driller in the desired direction; the wall support is then not necessary for this specific case. In vertical drilling, the user, to ensure synchronization with the driller, will have to adapt the masses according to the height of the drilling.
Une manette (21) permet le re bobinage de la câblette (19) dans sa gorge de poulie, ainsi que la remontée du foreur. Deux rondelles plastique ou métalliques (22) sont placées latéralement de chaque côté de la poulie (18) et contre l' entretoise (25) afin de limiter le déplacement axial de cette dernière.A handle (21) allows the rewinding of the cable (19) in its pulley groove, as well as the ascent of the driller. Two plastic or metal washers (22) are placed laterally on each side of the pulley (18) and against the spacer (25) in order to limit the axial movement of the latter.
Une autre rondelle (23) répartira la force de serrage des écrous papillon (24) sur le tube métallique (17). Une entretoise (25) permettra la rotation de la poulie, malgré le serrage de l'ensemble des pièces par les écrous (24).Another washer (23) will distribute the tightening force of the wing nuts (24) on the metal tube (17). A spacer (25) will allow the pulley to rotate, despite the tightening of all the parts by the nuts (24).
Un galet presseur (26) assure le plaquage du câble d'alimentation (12) du foreur dans sa phase de forage afin d'éviter les glisssements du câble dans sa gorge. Ce galet presseur (26) est soutenu par les tubes métalliques (27) et (28).A pressure roller (26) ensures the plating of the supply cable (12) of the driller during its drilling phase in order to avoid slipping cable in its throat. This pressure roller (26) is supported by the metal tubes (27) and (28).
Ces mêmes tubes abritent à l'intérieur le ressort (29) assurant le plaquage du galet presseur (26) contre le câble (12) du foreur. Les 2 tubes creux (27) et (28), de section différente, coulissent l'un dans l'autre - l'extrémité du tube (27), lui aussi aplati, permettra le pincement du ressort (29) et sera, lui aussi, poinçonné en forme de carré de façon à rentrer dans l'axe (15).These same tubes shelter the spring inside (29) ensuring the pressing of the pressure roller (26) against the cable (12) of the driller. The 2 hollow tubes (27) and (28), of different section, slide one inside the other - the end of the tube (27), also flattened, will allow the spring (29) to be pinched and will be also, punched in the shape of a square so as to enter the axis (15).
Le tube (28) sera aplati à son extrémité de façon à recevoir la vis (30) servant d'axe au galet presseur (26). La vis sera bloquée perpendiculairement au tube (28) grâce aux écrous (31). Le galet presseur (26) se compose d'un cylindre métallique ou en plastique venant se glisser sur la vis (30), de façon à tourner librement.The tube (28) will be flattened at its end so as to receive the screw (30) serving as an axis for the pressure roller (26). The screw will be locked perpendicular to the tube (28) using the nuts (31). The pressure roller (26) consists of a metal or plastic cylinder sliding on the screw (30), so as to rotate freely.
A titre d'exemple non limitatif, le foreur aura des dimensions de l'ordre de 22 mm pour le diamètre, de 68 mm pour la longueur et de 15 m pour le câble d'alimentation.By way of nonlimiting example, the driller will have dimensions of the order of 22 mm for the diameter, 68 mm for the length and 15 m for the power cable.
