Abstract
Description
La présente invention est relative à un dispositif pour noyer des douilles filetées,ou analogues, dans une dalle de béton coulée à plat. The present invention relates to a device for embedding threaded bushings, or the like, in a concrete slab cast flat.
En l'état actuel de la technique, on connait un procédé qui consiste à couler des dalles de béton à plat, dans un moule formé par la coopération d'une surface plane et d'un cadre,ce dernier étant constitué par des règles disposées sur chant et formant bordures de contenance. In the current state of the art, a process is known which consists in pouring concrete slabs flat, in a mold formed by the cooperation of a flat surface and a frame, the latter being constituted by rules arranged on edge and forming capacity borders.
Dans la demande de brevet Français N0 88 02752 du 4 Mars I988 aux noms des demandeurs, on avait décrit et revendiqué des moyens permettant de noyer des douilles filetées dans une dalle de béton, l'axe du filetage étant disposé perpendiculairement au plan de la dalle. In the French patent application N0 88 02752 of March 4, I988 in the names of the applicants, we had described and claimed means allowing to drown threaded sleeves in a concrete slab, the thread axis being arranged perpendicular to the plane of the slab .
Les moyens décrits dans cette demande nécessitaient l'utilisation de blocs de réserve et de supports compliqués et coûteux ces derniers restant noyés dans le béton. The means described in this application required the use of complicated and expensive reserve blocks and supports, the latter remaining embedded in the concrete.
De plus, les moyens de mise en oeuvre impliquaient que l'orifice de la douille filetée débouche sur l'une des faces de la dalle. In addition, the means of implementation implied that the orifice of the threaded sleeve opens onto one of the faces of the slab.
Parfois, on n'utilise pas de blocs de réservation et d'éléments d'entretoisement permettant leur calage et, dans ce cas, les moyens décrits dans la demande de brevet précitée,pour positionner une douille filetée,ne peuvent pas être utilisés. Sometimes, use is not made of reservation blocks and bracing elements allowing their setting and, in this case, the means described in the aforementioned patent application, for positioning a threaded sleeve, cannot be used.
La présente invention, qui remédie à ces inconvénients, est remarquable en ce que la douille filetée est maintenue par une barre fixée par l'une de ses extrémités,au moins,contre la face interne d'une règle,parallèlement au plan de la dalle à couler, ladite douille étant engagée dans un orifice de la barre et maintenue sur celle-ci durant le coulage du béton par un manchon de positionnement comportant une vis susceptible de coopérer avec le filetage de la douille. The present invention, which overcomes these drawbacks, is remarkable in that the threaded sleeve is held by a bar fixed by one of its ends, at least, against the internal face of a rule, parallel to the plane of the slab. to be cast, said sleeve being engaged in an orifice of the bar and held thereon during the pouring of the concrete by a positioning sleeve comprising a screw capable of cooperating with the thread of the sleeve.

En se reportant aux dessins, on voit que le problème à résoudre consiste à noyer une douille filetée du commerce dans une dalle en béton coulée à plat,dans un moule constitué par une surface plane 1 et par des règles 2 formant bordures de contenance. Referring to the drawings, it can be seen that the problem to be solved consists in embedding a commercial threaded bush in a concrete slab cast flat, in a mold constituted by a flat surface 1 and by rulers 2 forming capacity borders.
La douille présente une partie cylindrique 3 filetée intérieurement en 4 et dont une extrémité 5 est écrasée et repliée pour former une patte d'ancrage. The sleeve has a cylindrical part 3 internally threaded at 4 and one end of which 5 is crushed and folded back to form an anchoring lug.
Selon l'invention, la douille est engagée dans une barre 6, perpendiculairement à cette dernière qui est maintenue par une de ses extrémités, au moins,contre la règle 2 parallèlement au plan de la dalle à réaliser. According to the invention, the sleeve is engaged in a bar 6, perpendicular to the latter which is held by one of its ends, at least, against the rule 2 parallel to the plane of the slab to be produced.
Selon un mode de réalisation, la barre 6 est constituée par un tronçon de tube de section rectangulaire présentant, en coïncidence selon deux faces opposées,des trous 7 et 8,circulaires. According to one embodiment, the bar 6 is constituted by a section of tube of rectangular section having, coincidentally on two opposite faces, holes 7 and 8, circular.
Le maintien de la douille est assuré par un manchon 9,susceptible de coiffer l'extrémité cylindrique de la douille et présentant une vis 10 pouvant coopérer avec le filetage 4 de ladite douille. The sleeve is maintained by a sleeve 9, capable of covering the cylindrical end of the sleeve and having a screw 10 which can cooperate with the thread 4 of said sleeve.
L'extrémité du manchon 9, disposée vers la barre 6,présente une partie épaulée 11 qui pénètre et s'ajuste dans le trou 8 en prenant appui contre la face correspondante de la barre 6. The end of the sleeve 9, disposed towards the bar 6, has a shoulder portion 11 which penetrates and adjusts in the hole 8 by pressing against the corresponding face of the bar 6.
I1 s'avère donc que le manchon 9 remplit une pluralité de fonctions:
-il maintient la douille sur la barre;
-il protège le filetage intérieur 4;
-il coopère avec la barre à positionner, l'axe du filetage perpendiculairement à ladite barre.It therefore turns out that the sleeve 9 fulfills a plurality of functions:
-it keeps the socket on the bar;
-it protects the internal thread 4;
it cooperates with the bar to be positioned, the axis of the thread perpendicular to said bar.
L'extrémité du manchon 9,opposée à l'épaulement ll,est pourvue de moyens permettant sa manoeuvre. Ainsi,elle peut présenter un évidement 12 et une goupille transversale 13. The end of the sleeve 9, opposite the shoulder ll, is provided with means allowing its operation. Thus, it can have a recess 12 and a transverse pin 13.
I1 faut noter que les manchons 9 sont récupérés après la prise du béton et peuvent être réutilisés. It should be noted that the sleeves 9 are recovered after the concrete has set and can be reused.
La barre 6 comporte à l'une de ses extrémités, au moins,un écrou 14 permettant sa fixation à l'aide d'un boulon 15. The bar 6 has at least one of its ends at a nut 14 allowing it to be fixed using a bolt 15.
Pour fixer la barre 6 et la positionner correctement, on utilise une équerre 16 qui présente,au moins, un chant parallèle ou perpendiculaire au chant de la règle 2. L'équerre 16 est rendue solidaire d'une réglette 17 susceptible de prendre appui contre le chant supérieur de la règle ( figure 6). To fix the bar 6 and position it correctly, a bracket 16 is used which has, at least, a edge parallel or perpendicular to the edge of the rule 2. The bracket 16 is made integral with a strip 17 capable of bearing against the upper edge of the ruler (figure 6).
Selon un mode de réalisation,la barre 6 est formée de plusieurs tronçons tels que celui 6a qui peut coulisser librement et sans jeu dans celui 6, l'immobilisation axiale des deux tronçons aboutés s'effectuant très simplement à l'aide d'une clavette 18,plate et à bords parallèles 18a, engagée dans les trous 7-8,la largeur de la clavette étant égale au diamètre desdits trous et le coincement étant d'autant plus important que ladite clavette est plus épaisse. According to one embodiment, the bar 6 is formed of several sections such as that 6a which can slide freely and without play in that 6, the axial immobilization of the two butted sections being carried out very simply using a key 18, flat and with parallel edges 18a, engaged in the holes 7-8, the width of the key being equal to the diameter of said holes and the wedging being all the more important as said key is thicker.
Bien entendu, la présente invention ne se limite pas au mode de réalisation décrit et représenté mais s'étend, au contraire, à toutes variantes de formes et dimensions. Of course, the present invention is not limited to the embodiment described and shown but extends, on the contrary, to all variants of shapes and dimensions.
C'est ainsi,entre autres, que la barre 6 et les tronçons 6a peuvent affecter,en section,une forme en U couché,comme montré sur la figure 5. Thus, among other things, the bar 6 and the sections 6a can have, in section, a coated U-shape, as shown in FIG. 5.
