Abstract

The bolt has shank (1) with different diameters, formed by plastic deformation of material for forming a fiber. The shank has smooth zones (6-1, 7-1, 8-1), which are corrected and adjusted with a bore of a smooth bush, where the bush receives grooves that house O-ring joints for sealing a smooth zone of the bush, on its outer diameter. Opening elements i.e. straight plates, are positioned in a groove (3-1) of the shank.

Description

1 La présente invention est un boulon aveugle de pré assemblage destiné àThe present invention is a blind pre-assembly bolt for

maintenir sous tension des éléments pré usinés et devant être assemblés définitivement. De part sa haute résistance il permet le déplacement et le transport des éléments. Il offre l'avantage d'être démontable facilement et réutilisable immédiatement.  keep pre-machined and permanently assembled components under tension. Due to its high resistance it allows the movement and transportation of the elements. It offers the advantage of being removable easily and reusable immediately.

Il est doté sur sa longueur d'une douille qui a pour but de servir de centrage des éléments pré assemblés. Avec l'ensemble des joints toriques, il offre également une bonne étanchéité empêchant le fluage des mastics destinés à créer l'étanchéité entre les éléments qui seront définitivement assemblés. Sa pose et sa dépose sont rapides.  It is equipped on its length with a socket which aims to center the pre-assembled elements. With all the O-rings, it also offers a good seal preventing creep sealants intended to create the seal between the elements that will be permanently assembled. Its installation and removal are fast.

1 La tige (1) est composée de plusieurs diamètres et d'un filetage. Elle est obtenue par déformation plastic du matériau matriçage afin d'obtenir un fibrage ce qui lui donne une bonne résistance à la tension.1 The rod (1) is composed of several diameters and a thread. It is obtained by plastic deformation of the matrix material in order to obtain a fiber drawing which gives it good resistance to tension.

10 Elle a une tête (1/1) suivie d'une face angulaire (2/1) raccordée par un rayon gaieté et une gorge (3/1) offrant une petite zone lisse raccordée elle aussi par un rayon gaieté rejoignant la zone lisse (6/1) et l'épaulement (4/1) qui lui aussi est raccordé par un rayon gaieté rejoignant la zone lisse (7/1) puis la gorge (5/1) et la zone lisse (8/1) et ensuite les zones 15 (9/1) et (10/1). Les zones (9/1) et (10/1) de cette tige sont parfaitement concentriques et reçoivent un usinage très fin sans trace d'outil pouvant provoquer une amorce de rupture. La zone (10/1) est raccordée par un rayon entre le dernier filet et la zone (9/1). Ce rayon est 20 tangent au diamètre de fond de filet et se raccorde à la face angulaire de l'amorce de rupture. Les zones (6/1) (7/1) (8/1) sont rectifiées et ajustées avec l'alésage (5/3) de la douille (3) Fig.3 afin d'obtenir un parfait glissement sans jeu. La zone (9/1) est usinée sans trace 25 d'outil, la zone (10/1) le filetage est obtenu par déformation plastic roulage avec entrée de filet rayonné, elle reçoit un chanfrein en entrée de filetage pour lui permettre une bonne prise de vissage dans la douille (2).It has a head (1/1) followed by an angular face (2/1) connected by a cheerful ray and a groove (3/1) providing a small smooth zone also connected by a cheerful ray joining the smooth zone (6/1) and the shoulder (4/1) which is also connected by a cheerful ray joining the smooth zone (7/1) then the groove (5/1) and the smooth zone (8/1) and then zones 15 (9/1) and (10/1). The zones (9/1) and (10/1) of this rod are perfectly concentric and receive a very fine machining without trace of tool that can cause a beginning of rupture. The zone (10/1) is connected by a radius between the last thread and the zone (9/1). This radius is tangent to the bottom diameter of the thread and is connected to the angular face of the breakaway leader. The zones (6/1) (7/1) (8/1) are ground and adjusted with the bore (5/3) of the sleeve (3) Fig.3 to obtain a perfect slip without play. zone (9/1) is machined without any trace of a tool, the zone (10/1) the threading is obtained by plastic deformation rolling with entry of radiated net, it receives a chamfer at the thread inlet to allow it a good grip screwing in the socket (2).

3 2909143 5 LES ELEMENTS OUVRANTS (5) Fig.5 Les éléments ouvrants sont des lames droites de différentes épaisseurs ajustées en fonction du diamètre du boulon de pré assemblage. Elles ont une extrémité avec un pli à 90 (3/5) à angle droit qui se loge dans la gorge (3/1) de la tige (1) Fig.1. Elles sont maintenues en 10 place par un joint torique dans la zone (1/5) suivie d'une zone lisse (7/5) qui rejoint une seconde gorge plus large (8/5) suivie d'une zone lisse (10/5) et d'une face (2/5) qui prend appui sur la face des éléments à assembler côté inaccessible. Par ailleurs la face inférieure des éléments ouvrants 5 (Fig. 5) est dotée après la zone de pli 15 à 90 (3/5) d'une zone lisse (11/5) et d'une gorge (4/5) dans laquelle prend place l'épaulement (4/1) de la tige (1) Fig. 1 dans la position "éléments fermés" suivie d'une zone lisse (9/5) qui rejoint par un angle la zone (5/5) des éléments ouvrants qui sont au nombre de 3 disposés à 120 . Leurs faces supérieures sont usinées de forme cylindrique zone (12/5), prenant le même rayon que celui de la douille (3) du boulon avant introduction. Ceci 20 permet une bonne introduction dans l'alésage prévu à cet effet et une extraction facile. Pour obtenir la dépose de ce boulon il suffit de libérer la tension sur la tige (1) en dévissant la douille (2) et en provoquant un jeu, puis une poussée sur la douille (2). Ceci facilite le retour en position initiale des éléments (5) sur le diamètre de la tige (1).3 2909143 5 THE OPENING ELEMENTS (5) Fig.5 The opening elements are straight blades of different thicknesses adjusted according to the diameter of the pre-assembly bolt. They have an end with a fold at 90 (3/5) at right angle which is housed in the groove (3/1) of the rod (1) Fig.1. They are held in place by an O-ring in the zone (1/5) followed by a smooth zone (7/5) which joins a second wider groove (8/5) followed by a smooth zone (10 / 5) and a face (2/5) which bears on the face of the elements to be assembled inaccessible side. Furthermore, the underside of the opening elements 5 (FIG 5) is provided after the fold zone 15 to 90 (3/5) of a smooth zone (11/5) and a groove (4/5) in which takes place the shoulder (4/1) of the rod (1) FIG. 1 in the position "closed elements" followed by a smooth zone (9/5) which joins by an angle the zone (5/5) of the opening elements which are 3 in number arranged at 120. Their upper faces are machined cylindrical zone (12/5), taking the same radius as that of the sleeve (3) of the bolt before introduction. This allows a good introduction into the bore provided for this purpose and easy extraction. To remove this bolt simply release the tension on the rod (1) by unscrewing the sleeve (2) and causing a game, then a push on the sleeve (2). This facilitates the return to initial position of the elements (5) on the diameter of the rod (1).

Par ailleurs son alésage (5/3) est ajusté avec le diamètre de la zone (7/1) et(8/1) de la tige (1) afin d'obtenir un centrage parfait des éléments constitutifs de ce boulon aveugle de pré 20 assemblage.3 The smooth bush (3) consists of a smooth zone (2/3) and receives on its outer diameter two grooves (3/3) intended to house O-rings for sealing this zone and then a second smooth zone (4/3) for extending the smooth bushing to the second zone 10 of the elements to be assembled by are outer diameter adjusted to the different bores of the elements to be assembled. Its outer diameter also aims to index the elements between them which allows the user to use this bolt as a basis for a final fixation. It also has a face (1/3) perfectly perpendicular with its bore (5/3) and its outside diameter which is also reproduced on the face (6/3). Moreover its bore (5/3) is adjusted with the diameter of the zone (7/1) and (8/1) of the rod (1) in order to obtain a perfect centering of the constituent elements of this blind blind bolt.
