DEMANDE DE PREMIER CERTIFICAT D'ADDITION
A LA DEMANDE DE BREVET N" 84 13471 DU 29.08.84
RADIER SUR PICOTS, ET DISPOSITIFS POUR SA MISE EN OEUVRE
La présente invention concerne des perfectionnements aux radiers sur picots décrits dans le brevet principal N 84 13471.APPLICATION FOR FIRST ADDITION CERTIFICATE
AT THE PATENT APPLICATION NO. 84 13471 OF 29.08.84
DELETE ON SPOTS, AND DEVICES FOR ITS IMPLEMENTATION
The present invention relates to improvements to the rafts on pins described in the main patent N 84 13471.
Dans ce type de radier on a prévu dans ledit brevet principal une liaison par acier, et de renfort dans le cas des picots béton et une collerette soudée dans le cas des picots métalliques. Or, il 5 ' avère plus économique conformément à la présente invention d'effectuer un élargissement des têtes qui, dans le cas du battage à l'aide d'un mandrin1 est réalisé en mettant en forme la tête du mandrin et, dans le cas du picot métallique pour dallage existant, en terrassant la tête du picot dans le support du dallage. Ces élargissements permettent une meilleure liaison radier/picot et réduisent la portée entre appuis. In this type of raft is provided in said main patent a steel connection, and reinforcement in the case of concrete pins and a welded flange in the case of metal pins. Now, it turns out to be more economical in accordance with the present invention to carry out a widening of the heads which, in the case of threshing using a mandrel1 is carried out by shaping the head of the mandrel and, in the case metallic stud for existing paving, by digging the stud head into the paving support. These widenings allow a better connection to radiate / spike and reduce the range between supports.
La présente invention a donc pour objet un radier sur picots comportant une dalle en béton armé prenant appui sur des éléments cylindriques ou picots fichés dans le sol, caractérisé en ce que chaque picot se raccorde à la dalle par l'intermédiaire d'une section qui va en s'élargissant au fur et à mesure que l'on se rapproche de la dalle. The present invention therefore relates to a raft on spikes comprising a reinforced concrete slab bearing on cylindrical elements or spikes stuck in the ground, characterized in that each spike is connected to the slab via a section which widens as you get closer to the slab.
L'invention concerne également un radier plus particulièrement destiné à un dallage préexistant dans lequel sont réalisés des trous, la tête des picots étant scellée dans le dallage, ledit radier étant caractérisé en ce que chaque picot est constitué par un tube métallique scellé dans son trou de logement ainsi que dans une tête en micro-béton, de préférence de forme conique, réalisée dans le sol sous le dallage. The invention also relates to a slab more particularly intended for a pre-existing paving in which holes are made, the head of the pins being sealed in the paving, said slab being characterized in that each spike is constituted by a metal tube sealed in its hole housing as well as in a micro-concrete head, preferably conical, made in the ground under the paving.
Enfin, l'invention concerne en outre des dispositifs pour la mise en oeuvre de ces radiers et plus précisément un mandrin télescopique ainsi qu'un batteur pour la réalisation des picots autour des bâtiments existants ou à l'intérieur. Finally, the invention also relates to devices for the implementation of these rafts and more specifically a telescopic mandrel and a beater for the production of pins around existing buildings or inside.

tion du picot suivant la figure 3.Other characteristics and advantages of the invention will appear on reading the detailed description which follows and which is given with reference to the appended drawings, in which
- Figure 1 shows a longitudinal section of a
concrete stud according to the invention
- Figure 2 shows a longitudinal section of a
mandrel according to the invention for producing the
spike of figure 1
- Figure 3 shows a longitudinal section of a
metal pin for pre-existing paving, and;
- Figure 4 shows a longitudinal section of a bat
automatic teur according to the invention for carrying out
tion of the pin according to figure 3.
A la figure 1, on a représenté en 41 la partie élargie d'un picot en béton 42. Cette partie 41 de raccordement du picot à la dalle peut avoir une forme tronconique de préférence, ou autre, et est destinée à assurer une meilleurs assise à la superstructure de l'ouvrage. In Figure 1, there is shown at 41 the enlarged part of a concrete pin 42. This part 41 for connecting the pin to the slab may preferably have a frustoconical shape, or other form, and is intended to ensure better seating. to the superstructure of the structure.
A la figure 2, est représenté un mandrin télescopique permettant de former dans le sol les élargissements 41 des picots en béton 42. In FIG. 2, a telescopic mandrel is shown making it possible to form in the ground the enlargements 41 of the concrete studs 42.
Le mandrin est conforme du brevet principal et comprend un élément métallique cylindrique inférieur 43 muni d'un fond et un élément métallique cylindrique supérieur 44 pouvant coulisser coaxialement sur l'élément inférieur d'une certaine amplitude grâce à un jeu de tenons et fentes 45. A la partie supérieure l'élément 44 s'élargit par une paroi tronconique 46. The mandrel conforms to the main patent and comprises a lower cylindrical metallic element 43 provided with a bottom and an upper cylindrical metallic element 44 which can slide coaxially on the lower element of a certain amplitude by means of a set of tenons and slots 45. At the upper part, the element 44 widens by a frustoconical wall 46.
A la figure 3, qui est une coupe sur un dallage existant 47, est représenté un tube métallique 48 d'un picot, fermé à son extrémité inférieure et engagé dans un trou 49 réalisé à cet effet dans le dallage 47 et scellé dans une tête en micro-béton 50, taillée dans le sol support du dallage. La tête 50 a une forme générale, de préférence, de cône inversé. In Figure 3, which is a section on an existing paving 47, is shown a metal tube 48 of a spike, closed at its lower end and engaged in a hole 49 made for this purpose in the paving 47 and sealed in a head in micro-concrete 50, cut in the soil supporting the paving. The head 50 has a general shape, preferably, of an inverted cone.
A la figure 4, est représenté un batteur automatique plus spécialement destiné à la réalisation des picots de la figure 3, et qui se compose d'un mouton 51 constitué d'un barreau métallique coulissant dans un tube de picot 48 et manoeuvré par un câble 52 passant sur un jeu de poulies fixes de renvoi 53a,53b,53c,53d,53e et sur une poulie d'entraînement mobile 54 solidaire de la tige d'un vérin à air comprimé 55. In Figure 4, there is shown an automatic mixer more specifically intended for the production of the pins of Figure 3, and which consists of a sheep 51 consisting of a metal bar sliding in a spike tube 48 and operated by a cable 52 passing over a set of fixed return pulleys 53a, 53b, 53c, 53d, 53e and over a movable drive pulley 54 secured to the rod of a compressed air cylinder 55.
L'extrémité du brin du câble 52 est tenue par un treuil 56 solidaire de la tête du tube 48.The end of the cable strand 52 is held by a winch 56 secured to the head of the tube 48.
A ce système de mouflage, une course de la poulie 54 provoque pour le mouton 51 une chute de hauteur double. In this hauling system, a stroke of the pulley 54 causes the sheep 51 to drop from double height.
Le treuil 56 permet de régler la longueur du câble52 afin que l'on obtienne une bonne percussion du mouton sur le fond du tube. The winch 56 makes it possible to adjust the length of the cable 52 so that a good impact of the sheep is obtained on the bottom of the tube.
La fixation du treuil 56 sur le tube permet de maintenir constante la frappe du mouton puisque le câble s'allonge côté mouton de la même longueur que celle de la descente du tube. Attaching the winch 56 to the tube keeps the strike of the sheep constant since the cable lengthens on the sheep side of the same length as that of the descent of the tube.
Deux vannes de fin de course 57a et 57b réglables, permettent d'automatiser le mouvement du vérin 55 et la course. Two adjustable limit switches 57a and 57b, automate the movement of the jack 55 and the stroke.
