Abstract

The equipment has horizontal metallic installation plates (4), and a gangway (5) arranged between the plates for circulation of an operator. The plates support a beam (2) during a wedging operation, where the plates are fixed on vertical supports (1) e.g. shoring towers. Each plate has a mecano-soldered metallic frame on which a planking made of sheet is fixed, where each planking has an opening for passage of an operator. Guide-rails are arranged on three sides of the plates, where guide-rails are retractable and lockable from ground.

Description

La présente invention concerne un équipement servant à supporter et àThe present invention relates to equipment for supporting and

maintenir une poutre en béton en position horizontale pendant le clavetage de celle ci au dessus d'un poteau.  maintain a concrete beam in horizontal position during the keying of the latter above a post.

Cette fonction est traditionnellement effectuée par un ensemble de tours d'étaiement ou d'étais simples surmontés de poutres en bois sur lesquelles on solidarise la poutre à claveter. Le poteau sur lequel la poutre doit être clavetée est ainsi entourée par ces tours ou étaies.  This function is traditionally performed by a set of shoring towers or simple props topped with wooden beams on which is secured the beam to key. The post on which the beam is to be keyed is thus surrounded by these towers or stalls.

Le principal inconvénient de ce type de solution est que d'une part la 1s poutre à claveter est très difficilement maintenue horizontalement pendant le clavetage, et d'autre part la sécurité des opérateurs n'est pas parfaitement assurée.  The main disadvantage of this type of solution is that on the one hand the 1s beam claveter is very difficult to maintain horizontally during keying, and secondly the safety of operators is not perfectly ensured.

L'équipement selon l'invention permet de remédier à ces 20 inconvénients. La figure 1 illustre le principe de l'équipement. Il comporte selon une première caractéristique :  The equipment according to the invention overcomes these disadvantages. Figure 1 illustrates the principle of equipment. It comprises according to a first characteristic:

sur cette figure sont également représentés la poutre à claveter (2) et le poteau (3). 30 Les supports sont des structures tubulaires mécano soudées ils sont munis d'un dispositif d'accès à la partie supérieure. Sur ces supports sont fixés les plateaux proprement dits. Ceux-ci sont constitués d'un châssis rigide sur lequel est soudée une tôle pour former le platelage.  in this figure are also shown the key beam (2) and the post (3). The supports are welded tubular structures they are provided with a device for access to the upper part. On these supports are fixed the trays themselves. These consist of a rigid frame on which is welded a sheet to form the decking.

Ce platelage est muni d'une trappe d'accès et d'une passerelle et est bordé de garde-corps escamotables manoeuvrables depuis le sol. Chaque plateau est broché sur son support afin que l'ensemble puisse être déplacé à la grue ceci grâce à des anneaux de levage. Les supports sont modulaires de façon à adapter la hauteur de l'ensemble à la hauteur du poteau. Le contrôle de l'horizontalité de l'ensemble se fait par un niveau intégré au plateau.  This decking is equipped with an access hatch and a walkway and is lined with retractable railings that can be maneuvered from the ground. Each tray is stuck on its support so that the whole can be moved to the crane this through lifting rings. The supports are modular so as to adapt the height of the assembly to the height of the post. The control of the horizontality of the whole is done by a level integrated in the plateau.

Selon les modes particuliers de réalisation :  According to the particular embodiments:

-le support mécano-soudé peut être composé de plusieurs modules superposés afin d'atteindre la hauteur du poteau. -le dispositif de contrôle de l'horizontalité peut être constitué soit de soit de un niveau à bulle, soit de deux niveaux à bulle, soit d'un système laser.  the mechanically welded support can be composed of several superimposed modules in order to reach the height of the post. the horizontality control device may consist of either a bubble level, two bubble levels, or a laser system.

-la partie basse du support peut être munie d'un dispositif qui lors du montage du support facilite le positionnement de celui-ci par rapport au poteau.  the lower part of the support may be provided with a device which, during mounting of the support, facilitates the positioning thereof relative to the post.
