Abstract

The moulding shutter back plate (1) is fixed to open profile traverses (4) by a Z shaped clip (2) pulled tight by bolts with countersunk heads (3). The traverses are in turn fixed to runners (8) by stirrups (6) spanning the runner and held by a clip (5). The traverses are made up of a combination of Z and angle profiles. The platform is supported on adjustable legs (9) and reinforced by cross bracing (15) fixed at one end to a cope (12) and at the other end to a frame (13) which provides longitudinal bracing to the vertical legs.

Description

La présente invention concerne les tables de coffrage extensibles, plus particulièrement en largeur et aussi éventuellouent en longueur.  The present invention relates to extendable formwork tables, more particularly in width and also optionally in length.

On connait des tables de coffrage extensibles en largeur comportant une peau,généralement en contre-plaqué,fixée sur des traverses extensibles constituées par des éléments femelles fixés sur des longerons extensibles ou non, et des éléments mâles qui coulissent dans les éléments femelles.There are known formwork tables that can be extended in width, comprising a skin, generally made of plywood, fixed on extendable crosspieces constituted by female elements fixed on beams which may or may not be extendable, and male elements which slide in the female elements.

Les éléments femelles sont en général des tubes carrés ou rectangulaires.The female elements are generally square or rectangular tubes.

Les éléments mâles sont en général des tubes carrés ou rectangulaires plus petits susceptibles de coulisser avec un jeu convenable dans les éléments femelles.On utilise aussi des tubes ronds ou des profilés à section en U.The male elements are generally smaller square or rectangular tubes capable of sliding with a suitable clearance in the female elements. Round tubes or profiles with U-section are also used.

De telles traverses extensibles présentent un certain nombre d'inconvé- nients:
-L'élément femelle est différent de l'élément mâle,donc la fabrication
nécéssite deux types de profilés.Such extendable sleepers have a number of drawbacks:
-The female element is different from the male element, so the manufacturing
two types of profiles are required.

-A résistance égale,l'élément niale,obligatoirement plus petit que
l'élément -femellesest plus lourd,donc plus onéreux.-A equal resistance, the nial element, necessarily smaller than
the female element is heavier, therefore more expensive.

-La fixation du contre-plaqué sur des traverses tubulaires n'est pas
simple.-The fixing of plywood on tubular sleepers is not
simple.

- Le jeu nécéssaire au coulissement nuit au bon alignement des éléments
male et femelle
La présente invention permet d'éviter ces inconvénients; en particulier elle permet de réaliser tous les éléments coulissants des traverses avec un sel type de profilé qui peut être considéré indifféremment comme nâle ou fenelle.Le contreplaqué peut être fixé facilement à l'aide de crapauds par des vis à bois ou des vis å étaux sans avoir à percer des trous dans les traverses et sans avoir a faire un traçage
préalable sur le contre-plaqué.- The play required for sliding interferes with the proper alignment of the elements
male and female
The present invention makes it possible to avoid these drawbacks; in particular, it allows all the sliding elements of the crosspieces to be made with a standard type of salt which can be considered indifferently as male or fenelle. The plywood can be easily fixed with the help of toads by wood screws or clamp screws. without having to drill holes in the sleepers and without having to make a tracing
prior to plywood.

La table de coffrage objet de l'invention comporte des traverses. The formwork table object of the invention comprises crosspieces.

extensibles dont les éléments mâles et femelles sont constitués de profilés ouverts en tôle pliée de section rigoureusement identiques puisque tirés dans la même barre,caractérîsés par le fait qu'ils sont superposables à eux-mêmes et empilables en nombre illimité.A titre d'exemple,parmi les profilés possèdant ces caractéristiques,on peut citer les cornières,les profilés en V ou en aY ou en Z,les profilés augedont la section est une fraetion de couronne circulaire plus petite qu'un quart de cercle.extendable, the male and female elements of which consist of open sections of folded sheet metal of strictly identical section since drawn in the same bar, characterized by the fact that they are stackable on themselves and stackable in unlimited numbers. , among the profiles having these characteristics, there may be mentioned the angles, the V-shaped or aY or Z-shaped profiles, the auged profiles of which the section is a cut of circular crown smaller than a quarter of a circle.

A titre d'exemple purement indicatif et nullement limitatif,la figure 1 représente en élévation une table extensible réalisée selon l'invention avec des traverses Z profilées à froid.La figure 4 représente la même table vue de face.La figure 3 représente un mode de fixation des traverses extensibles sur les longerons.La figure $ représente un mode de fixation des longerons coulissants extensibles sur les pieds de la table.Le contre-plaqué 1 est fixé sur les traverses extensibles 4 constituées par les éléments coulissants 4a et 4b,a l'aide de crapauds 2 serrés par des boulons à tête fraisée 3.Les traverses 4 sont fixées stoe longerons 8 à l'aide de crapauds 5 serrés par des étriers 6 qui traversent des guides 7 qui permettent le coulissement des traverses mais les empêchent de s'écarter l'une de l'autre.Sans percer aucun trou dans Iti traverses ni dans les longerons, on peut ainsi fixer très solidement Ieg traverses sur les longerons en ayant la possibilité de régler au préalable la longueur des traverses et leur espacement.Sous les longerons sont fixés,
l'aide d'étriers 6 des chapes 10 sur lesquelles s'articulent les montants 9 qui tourillonnent sur les axes 11.Dans le sens transversal, les montants S sont contreventés par des cadres 13 extensibles ou non, bridées par des étriers 14.Dans le sens longitudinal,les montants 9 sont contreventés par des bracons '5 articulés d'une part sur des axes 16 portés par des chapes 12 bridées sur les longerons 8 par des étriers 6 et d'autre part sur des broches à lumière 17 portées par les cadres 13.As a purely indicative and in no way limitative example, FIG. 1 shows in elevation an extendable table produced according to the invention with cross members Z cold profiled. FIG. 4 represents the same table seen from the front. FIG. 3 represents a mode for fixing the extendable rails to the side rails. Figure $ represents a method of fixing the extendable sliding beams to the legs of the table. The plywood 1 is fixed to the extendable beams 4 formed by the sliding elements 4a and 4b, a using toads 2 tightened by countersunk bolts 3. The crosspieces 4 are fixed stoe longitudinal members 8 using toads 5 tightened by stirrups 6 which pass through guides 7 which allow the crosspieces to slide but prevent them from deviate from each other.Without drilling any holes in Iti crosspieces or in the longitudinal members, one can thus very securely fix Ieg sleepers on the longitudinal members, having the possibility of adjusting the length beforehand. cross beams and their spacing. Under the side rails are fixed,
using stirrups 6 of the yokes 10 on which the uprights 9 which revolve on the axes 11 are articulated. In the transverse direction, the uprights S are braced by frames 13 extendable or not, clamped by stirrups 14.In in the longitudinal direction, the uprights 9 are braced by struts' 5 articulated on the one hand on axes 16 carried by clevis 12 flanged on the side members 8 by stirrups 6 and on the other hand on light pins 17 carried by the frames 13.

Il est ainsi possible de déverrouiller rapidement la broche a lumière 17 qui maintient l'extrêmité du bracon 15,de rabattre le bracon sous le longeron et de rabattre les montants sous les longerons.L'encombrement vertical de la table se trouve ainsi pratiquement réduit à l'épaisseur du coffrage augmentée des épaisseurs des montants et du cadre 13.It is thus possible to quickly unlock the light pin 17 which maintains the end of the container 15, to fold the container under the side member and to fold the uprights under the side members. The vertical size of the table is thus practically reduced to the thickness of the formwork increased by the thicknesses of the uprights and the frame 13.

Si on désire utiliser des longerons extensiblesson peut les réaliser avantageusement,comme représenté sur la figure 4,à l'aide de deux ou plusieurs profilés métalliques U en tôle pliée, coulissant l'un dans l'autre en se faisant vis à vis.Ces profilés à froid, de sections rigoureusecent identiques,8a et 8b,sont maintenus solidement bridés l'un sur l'autre par les étriers 6 qui servent à fixer les chapes 10 et par tous ceux qui servent à fixer les traverses extensibles 4.Grâce à tous ces bridages,la continuité du longeron est parfaitement assurée. If one wishes to use extensiblesson beams can realize them advantageously, as shown in Figure 4, using two or more metal profiles U in folded sheet, sliding one inside the other while facing each other. cold sections, of identical rigorous sections, 8a and 8b, are held securely clamped one on the other by the stirrups 6 which serve to fix the yokes 10 and by all those which serve to fix the extendable sleepers 4.Thanks to all these clamps, the continuity of the spar is perfectly ensured.
