Abstract

The invention relates to a device making it possible to reduce the concentration of forces at the border of the concrete panel in all the phases of the operation. Use is thus made of a constant couple for distributing the forces at the foot of the anchor which is embedded in the panel. The invention consists of an anchor (2) embedded in the concrete, of a linking piece (1) articulated to the parallelogram system closed by the body (4) equipped with the safety rod (15) of the adjustable compression rod (6-16-17-) of the rocking (tipping) bar (9). The length of the rocking (tipping) bar (9) can vary as a function of the different lengths of the anchor (2) which are used according to the weight of the concrete panels. In order to manipulate the panel flat, use is then made of two opposite anchoring points for all the phases of the operation. The device according to the invention is intended particularly for manipulating panels in young (fresh) concrete, eliminating the risk of them breaking at the handling points.

- The connecting piece (T) between the hook and the anchor (2) embedded in the concrete panel (3) of approximately ovoidal shape constituting one of the sides of the parallelepiped, comprising a groove of shape suitable for receiving the anchor head (2) embedded in concrete (3).

Cette pièce de liaison est traversée par deux axes(5) qt (7) permettant l'articulation du parallépipède déformable représentant l'essentiel du squelette du CROCHET à BASCULE. This connecting piece is crossed by two axes (5) qt (7) allowing the articulation of the deformable parallelepiped representing the essential part of the skeleton of the HOOK TO ROCKER.

Cette pièce de liaison comporte deux ouvertures latérales de forme adaptée à la cinématique du crochet,afin de laisser libre passage à la tige de sécurité(15). This connecting piece has two lateral openings of shape adapted to the kinematics of the hook, in order to allow free passage to the safety rod (15).

-La manille(13)s'articule autour de l'axe(14) et permet l'ac crochage à l'appareil de levage. -The shackle (13) revolves around the axis (14) and allows hooking the lifting device.

-La tige de sécurité(15) liée au corps(4) permet le blocage de l'ancre (2) noyée dans le panneau en béton(3) lorsqu1elle est engagée dans la pièce de liaison(I),assurant ainsi la sécurité, lors des différentes phases d'utilisation du CROCHET àBASCULE. -The safety rod (15) linked to the body (4) allows the anchor (2) embedded in the concrete panel (3) to be blocked when it is engaged in the connecting piece (I), thus ensuring safety, during the different phases of use of the TILT HOOK.

-L'axe(5)assure la rotation entre la pièce de liaison et le corps(4). -The axis (5) ensures rotation between the connecting piece and the body (4).

Le dessin 6/6,figure6 représente pour la mise en oeuvre du crochet à bascule(crochet replié et ancre à l'horizontale).LA figure6 représente la configuration du CROCHET à à lors de la phase initiale consistant à libérer la gorge de la pièce de liaison(I),afin d'y introduire la tête de l'ancre moyée dans le béton étant en position horizontale. The drawing 6/6, figure 6 represents for the implementation of the rocking hook (folded hook and horizontal anchor). THE figure 6 represents the configuration of the HOOK at during the initial phase consisting in releasing the groove from the part of connection (I), in order to introduce the head of the anchor in the concrete being in the horizontal position.

Le dessin I/6,figure I représente le CROCHET à BASCULE en configuration développée après une légère traction sur la manille (I3), l'ancre(2) noyée dans le béton étant toujours à l'horizon- tale. Drawing I / 6, FIG. I represents the ROCKER HOOK in the configuration developed after a slight pull on the shackle (I3), the anchor (2) embedded in the concrete being always horizontal.

Après cette mise en configuration intervient la phase de décoffrage proprement dite. After this configuration takes place the formwork phase proper.

Dans cette configuration et le le eu des bras ce evier et de la longueur de l'ancre,les couples ainsi générés parm@ttent une distribution des efforts plus harmonieuse le long de l'ancre noyée dans le panneau en béton.Nous obtenons ainsi un @oefficient significativement plus élevé,et ce au cours de toutes les phase (décoffrage,relevage et pose à plat),que celui obtenu avec les méthodes employées jusqu'à ce jour.Autrement dit,par cette méthode,la force concentration à la bordure du panneau est diminuée. In this configuration and the size of the arms of this sink and of the length of the anchor, the torques thus generated by m @ ttent a more harmonious distribution of forces along the anchor embedded in the concrete panel. @oefficient significantly higher, and this during all the phases (formwork removal, lifting and laying flat), than that obtained with the methods used to date. In other words, by this method, the force concentration at the edge of the panel is decreased.

Le dessin 4/6,figure4 représente l'opération dite de relevage,venant juste après le décoffrage du panneau en béten.Lors de cette opération de relevage l'utilité du paraliépipède déformable apparaitra clairement.Le parallépipède déformable permet du panneau en béton,de sa valeur maximale à la valaur nulle, adaptant ainsi au mieux les efforts répartis suivant les différents angles adoptés par le panneau en béton lors de son opération de relevage. Drawing 4/6, figure 4 represents the so-called lifting operation, coming just after the formwork of the concrete panel has been stripped. During this lifting operation the usefulness of the deformable paralepiped will become clear. The deformable parallelepiped allows the concrete panel, its maximum value at zero valaur, thus optimally adapting the forces distributed according to the different angles adopted by the concrete panel during its lifting operation.

Le dessin5/6,figure5 représente l'opération de levage; la configuration autorise une dépose du panneau à l'horizontale regroupant tous les avantages énu@érés pour l'opératicn de relevage. The drawing 5/6, figure 5 represents the lifting operation; the configuration allows removal of the panel horizontally grouping all the advantages enu @ ered for the lifting operation.

Le dessin 5/6,figure 5 représente le décroche n distance en tirant la ficelle(15) à travers la poulie(17)qui commande par mécanicien.  Drawing 5/6, Figure 5 shows the distance n hook by pulling the string (15) through the pulley (17) which controls by mechanic.
