Abstract
Description
La présente invention a trait au domaine de la préfabrication de pièces en béton ou analogue et concerne tout spéciale- ment l'apport de perfectionnements à l'appareillage objet du brevet principal N080.00273, publié sous le N"2.472.967, du 8 Janvier 1980. The present invention relates to the field of prefabrication of concrete or similar parts and relates very specifically to the provision of improvements to the apparatus which is the subject of main patent N080.00273, published under No. 2,472,967 of 8 January 1980.
On a decrit dans ce brevet de base un dispositif de moulage par vibration constitué essentiellement par la combinaison de chevalets munis de vibrateurs et qui supportent une poutre longitudinale modulaire, avec des moules indépendants et interchangeables assujettis à la poutre (ou fausse poutre) par des moyens d'attaches rapides. In this basic patent, a vibration molding device has been described, essentially constituted by the combination of trestles provided with vibrators and which support a modular longitudinal beam, with independent and interchangeable molds secured to the beam (or false beam) by means quick couplers.
Dans ce système, on règle la puissance des vibrateurs en fonction du poids de la matière de moulage. La fausse poutre, non fixée par rapport aux chevalets, ne reçoit qu'une accélération et ne subit pas les jeformations imposes par les vibrateurs. In this system, the power of the vibrators is adjusted according to the weight of the molding material. The false beam, not fixed relative to the trestles, receives only an acceleration and does not undergo the jeformations imposed by the vibrators.
Un tel dispositif donne toute satisfaction et permet d'obtenir une vibration unidirectionnelle de bonne qualité. Toutefois, il présente l'inconvénient de provoquer beaucoup de bruit du fait de la difficulté de maintenir en contact la poutre et les chevalets par le seul réglage de la puissance des vibrateurs. Such a device is entirely satisfactory and makes it possible to obtain a good quality unidirectional vibration. However, it has the drawback of causing a lot of noise due to the difficulty of keeping the beam and the trestles in contact by the sole adjustment of the power of the vibrators.
L'invention a pour but d'obvier à cet inconvénient et d'éviter les phenomènes de battement de la fausse poutre sur les chevalets, tout en conservant le principe de base du dispositif susvise, selon lequel on évite de faire subir à la poutre la déformation imposée par les chevalets vibrants. The object of the invention is to obviate this drawback and to avoid the phenomena of the flapping of the false beam on the trestles, while retaining the basic principle of the above-mentioned device, according to which the beam is prevented from undergoing the deformation imposed by vibrating easels.
Conformément au perfectionnement apporte à machine du brevet principal, les chevalets et la fausse poutre sont rendus solidaires par la fixation sur les chevalets, de ventouses reliées à un système de vide et qui permettent de tirer la poutre sur les chevalets lorsque le vide est enclenché. In accordance with the improvement brought to machine of the main patent, the easels and the false beam are made integral by fixing on the easels, suction cups connected to a vacuum system and which allow the beam to be pulled on the easels when the vacuum is engaged.
Par ailleurs, une plaque de caoutchouc ou analogue est avantageusement intercalée entre les ventouses et la poutre de façon à mieux reduire le bruit et augmenter la plage de réglage de la puissance du vibrateur par rapport à la charge de matériau à mouler. Furthermore, a rubber plate or the like is advantageously interposed between the suction cups and the beam so as to better reduce the noise and increase the range of adjustment of the power of the vibrator relative to the load of material to be molded.
L'invention est illustrée par un mode d'exécution non limitatif représenté sur les dessins annexés qui montrent schematique ment.:
Figure 1 : une vue de profil d'un'dispositif de prefabrica-
tison de matériau durcissable (par exemple poteaux en beton)
par vibration, avec les perfectionnements de l'invention ;
Figure 2 : une vue en coupe de la même machine.The invention is illustrated by a non-limiting embodiment shown in the accompanying drawings which schematically show:
Figure 1: a profile view of a prefabricated device
brand of hardenable material (e.g. concrete posts)
by vibration, with the improvements of the invention;
Figure 2: a sectional view of the same machine.
On retrouve sur ces figures la structure générale de la machine objet du brevet principal, a savoir : le ou les moules 1 disposes sur la poutre (ou fausse poutre) 2 au moyen de systèmes d'attaches rapides (non représentés ici) ; les chevalets 3 équipés des vibrateurs 4, avec groupe vibreur 5, qui permettent de transmettre à la poutre 2 une vibration verticale et unidirectionnelle. These figures show the general structure of the machine which is the subject of the main patent, namely: the mold (s) 1 arranged on the beam (or false beam) 2 by means of quick coupler systems (not shown here); the easels 3 equipped with vibrators 4, with vibrator group 5, which transmit to the beam 2 a vertical and unidirectional vibration.
Conformement a l'invention, on a équipe les chevalets 3 de ventouses 6 qui sont reliées à un systeme d'aspiration par le vide (non représenté) et sur lesquelles on peut éventuellement disposer des plaquettes de caoutchouc 7. Lorsque la fausse poutre 2 parvient en position de vibration, on enclenche le vide ce qui provoque une traction de la poutre sur les chevalets. Ainsi la fixation entre la poutre et les chevalets garde une bonne élasticité, réglée par la puissance de la dépression. In accordance with the invention, the trestles 3 are fitted with suction cups 6 which are connected to a vacuum suction system (not shown) and on which it is possible to have rubber pads 7. When the false beam 2 reaches in the vibration position, the vacuum is triggered which causes the beam to pull on the trestles. Thus the fixing between the beam and the trestles keeps a good elasticity, regulated by the power of the depression.
En outre, il a été prevu tout autour de la machine des séries de panneaux 8, montés sur joints d'isolation 9 en mousse, destines à constituer une enveloppe d'insonorisation pendant les opérations de moulage. In addition, it has been provided all around the machine series of panels 8, mounted on insulation joints 9 in foam, intended to constitute a soundproofing envelope during the molding operations.
Comme dans le cas du brevet principal, le dispositif est utilisable pour tout type de matériau durcissable à mouler par vibration; comme par exemple du béton pour la réalisation d'éléments préfabriqués. As in the case of the main patent, the device can be used for any type of vibration-hardenable material; such as concrete for the production of prefabricated elements.
