Description

La présente invention a pour objet un cintre métallique pour la réalisation d'arcs ou de voûtes dans l'industrie du bâtiment.
Les cintres à cet usage sont généralement réalisés en bois et comportent un plancher ou paletage en arc de cercle épousant la forme de l'intrados de l'arc ou de la voûte à réaliser qui est soutenu par un bâti de poutres et fermes.
   Ces cintres en bois sont de dimensions invariables et donc adaptés à un seul type d'arc ou de voûte.
Dans le cas d'arcs ou de voûtes avec un arc de cintrage différent, il est nécessaire d'utiliser d'autres cintres.
En fait, il apparaít que ces cintres en bois sont pratiquement réalisés à la demande en fonction du chantier et qu'ils sont d'un remploi réduit d'autant qu'ils sont sujets à des détériorations, notamment au démontage et à des déformations par exemple du fait de l'humidité.The present invention relates to a metal hanger for the production of arches or vaults in the building industry.
The hangers for this use are generally made of wood and have a floor or pallet in an arc conforming to the shape of the underside of the arch or vault to be made which is supported by a frame of beams and trusses.
These wooden hangers are invariable in size and therefore suitable for a single type of arch or arch.
In the case of arches or vaults with a different bending arc, it is necessary to use other hangers.
In fact, it appears that these wooden hangers are practically produced on demand depending on the site and they are of a reduced re-use as far as they are subject to deterioration, in particular to disassembly and deformation by example due to humidity.

La présente invention se propose de remédier aux inconvénients ci-dessus par la conception d'un cintre tel que défini en une matière qui ne soit pas sensible à l'humidité, qui peut être du métal ou des matières synthétiques et/ou une combinaison de différents matériaux de ce type et qui soit adaptable en dimension à partir d'une dimension de base donnée, en sorte d'être réutilisable pour obtenir des arcs ou voûtes avec différentes longueurs, ce qui les rend d'emploi polyvalent et réutilisables.The present invention proposes to remedy the above drawbacks by the design of a hanger as defined in a material which is not sensitive to humidity, which can be metal or synthetic materials and / or a combination of different materials of this type which is adaptable in dimension from a given base dimension, so be reusable to get arches or vaults with different lengths, which makes them versatile and reusable.

A cet effet, le cintre selon l'invention comportant un paletage primaire constitué d'une paroi en arc de cercle supporté par un châssis se caractérise essentiellement en ce que le paletage cintré et son châssis ont une longueur variable à partir d'une valeur prédéterminée de base.To this end, the hanger according to the invention comprising a primary palletizing consisting of an arc wall supported by a chassis is characterized essentially in that the curved pallet and its frame have a length variable from a predetermined basic value.

Suivant une autre caractéristique de l'invention, le paletage cintré est porté par un châssis à montants inférieurs longitudinaux extensibles à partir d'une longueur donnée et à montants latéraux verticaux, à chaque extrémité des montants longitudinaux, qui sont également extensibles à partir d'une hauteur donnée.According to another characteristic of the invention, the curved pallet is carried by a chassis with longitudinal lower uprights extendable from of a given length and with vertical lateral uprights, at each end of the longitudinal uprights, which are also extendable from a height given.

Suivant encore une autre caractéristique de l'invention, sous le paletage primaire est articulée transversalement à deux montants verticaux parallèles extensibles, au moins une rallonge de paletage qui est extraite du paletage primaire par extension des montants longitudinaux du châssis.According to yet another characteristic of the invention, under the pallet primary is hinged transversely to two parallel vertical uprights extendable, at least one pallet extension which is extracted from the pallet primary by extension of the longitudinal uprights of the chassis.

Suivant encore une autre caractéristique de l'invention, sous le paletage primaire, est articulée à chacun des deux montants verticaux de chacune des extrémités du châssis une rallonge de paletage, les deux rallonges étant extraites par extension des montants longitudinaux parallèles du châssis à chacune de leurs extrémités.According to yet another characteristic of the invention, under the pallet primary, is articulated to each of the two vertical uprights of each of the ends of the chassis a pallet extension, the two extensions being extracted by extension of the parallel longitudinal uprights of the chassis to each of their ends.

Tel que représenté aux dessins annexés, le cintre selon l'invention (figures 1 et 2) présente un plancher ou paletage 1 en arc de cercle de la valeur correspondant au cintre ou à l'intrados à réaliser.
Le paletage 1 est relié par des flancs verticaux 2 parallèles formant coque autoporteuse à un fond 3 horizontal.
Sur le fond 3 sont disposés deux tubes carrés parallèles, un sur chaque paroi formant les flancs ; le fond et les montants longitudinaux et horizontaux du châssis ainsi que les tubes 4 constituent avec le paletage 1 les premiers éléments du châssis supportant le paletage 1 dit paletage primaire.As shown in the accompanying drawings, the hanger according to the invention (Figures 1 and 2) has a floor or pallet 1 in an arc of a value corresponding to the hanger or the underside to be produced.
The pallet 1 is connected by parallel vertical sides 2 forming a self-supporting shell to a horizontal bottom 3.
On the bottom 3 are arranged two parallel square tubes, one on each wall forming the sides; the bottom and the longitudinal and horizontal uprights of the chassis as well as the tubes 4 constitute with the pallet 1 the first elements of the chassis supporting the pallet 1 said primary pallet.

En figures 3, 4 et 5 est représenté l'ensemble des composants essentiels du cintre selon l'invention.
   En figure 3 est représentée une rallonge de paletage 5 constituée d'une paroi qui peut être cintrée en arc de courbe dont une extrémité 6 est libre et dont l'autre extrémité 7 est reliée par une articulation 8 à deux montants parallèles verticaux 9, lesquels sont fixés en extrémité de deux montants parallèles horizontaux 10.
Les montants verticaux 9 et horizontaux 10 sont constitués de tubes carrés.
Les montants horizontaux 10 s'engagent et coulissent dans les montants 4 parallèles horizontaux du châssis du cintre.In Figures 3, 4 and 5 is shown all of the essential components of the hanger according to the invention.
In Figure 3 is shown a pallet extension 5 consisting of a wall which can be bent in a curved arc, one end 6 of which is free and the other end 7 of which is connected by a hinge 8 to two vertical parallel uprights 9, which are fixed at the end of two horizontal parallel uprights 10.
The vertical uprights 9 and horizontal uprights 10 consist of square tubes.
The horizontal uprights 10 engage and slide in the horizontal parallel uprights 4 of the hanger frame.

Le montant 4 est doté d'une série de perçages sur une même ligne destinés à venir en regard l'un de l'autre lorsque les montants 10 sont extraits des montants 4 ou inversement lorsqu'ils sont rentrés dans les montants 4. Ces perçages permettent un réglage au moyen de goupilles traversantes non représentées.Amount 4 has a series of holes on the same line intended to come opposite each other when the amounts 10 are extracted amounts 4 or vice versa when they are entered in amounts 4. These holes allow adjustment by means of through pins not represented.

Le montant 9 est constitué de deux éléments tubulaires carrés verticaux dont un 9A est soudé à l'extrémité du montant 10 correspondant, l'autre 9B coulisse dans le premier et porte l'articulation 8 de la rallonge de paletage.
La position de 9A dans 9B est réglable par des perçages dont ils sont munis, qui reçoivent des goupilles.
Cette disposition permet de régler la hauteur du montant 9 entre une position basse (figure 4) et une position haute (figure 5). The upright 9 consists of two vertical square tubular elements, one of which 9A is welded to the end of the corresponding upright 10, the other 9B slides in the first and carries the articulation 8 of the pallet extension.
The position of 9A in 9B is adjustable by holes with which they are provided, which receive pins.
This arrangement makes it possible to adjust the height of the upright 9 between a low position (figure 4) and a high position (figure 5).

A chacune des extrémités des deux tubes 4 correspondent deux montants coulissants 10 avec leurs montants 9 correspondants.
Les montants 10 et 9 sont réunis de toute manière connue par exemple par une tôle entretoise réunissant deux montants parallèles fixés et verticaux 9A.At each end of the two tubes 4 correspond two sliding uprights 10 with their corresponding uprights 9.
The uprights 10 and 9 are joined in any known manner for example by a spacer sheet uniting two fixed and vertical uprights 9A.

A chaque extrémité du châssis primaire de la figure 1 correspond un système de rallonge de paletage avec deux montants verticaux 9, à coulisse, et deux montants horizontaux 10.At each end of the primary chassis of Figure 1 corresponds a pallet extension system with two vertical uprights 9, sliding, and two horizontal uprights 10.

Comme représenté en figures 1 et 2, à chaque extrémité du châssis primaire entre les flancs 2 et à faible distance du paletage fixe 1, un rondin soudé transversal 11 qui est disposé parallèlement à l'axe d'articulation 8 de la rallonge 5 et à un niveau supérieur à cet axe.
Les rondins 11 servent à la fois de soutien des rallonges 5 et d'organe de glissement de celles-ci lors de l'extraction de dessous, le paletage primaire.As shown in FIGS. 1 and 2, at each end of the primary chassis between the sides 2 and a short distance from the fixed pallet 1, a transverse welded log 11 which is arranged parallel to the articulation axis 8 of the extension 5 and at a level higher than this axis.
The logs 11 serve both to support the extensions 5 and to slide them during extraction from below, the primary palletizing.

Cette organisation du cintre selon l'invention permet à volonté comme représenté en figure 6 d'accroítre la longueur du cintre à partir d'une longueur prédéterminée de base qui est la longueur du paletage primaire tel que représenté à la figure 1.
Il est important pour que la ou les rallonges 5, lors de leur extraction, restent dans l'alignement de l'arc du cintre primaire 1, que la hauteur en extrémité des rallonges définie par les montants verticaux 9 soit réglable entre une hauteur maximum qui correspond à la position dans laquelle la rallonge est complètement dans le châssis primaire, la hauteur du montant 9 étant égale à la hauteur des flancs 2 en extrémité (figure 5) et une hauteur minimum qui est celle de l'extraction complète des rallonges comme représentée en figure 6.This organization of the hanger according to the invention allows at will as shown in Figure 6 to increase the length of the hanger from a predetermined base length which is the length of the primary pallet as shown in Figure 1.
It is important that the extension or extensions 5, during their extraction, remain in alignment with the arc of the primary hanger 1, that the height at the end of the extensions defined by the vertical uprights 9 is adjustable between a maximum height which corresponds to the position in which the extension is completely in the primary chassis, the height of the upright 9 being equal to the height of the sidewalls 2 at the end (FIG. 5) and a minimum height which is that of the complete extraction of the extensions as shown in figure 6.

A cet effet, le réglage s'effectue conjointement sur la longueur par allongement de celle-ci et sur la hauteur par réduction de celle-ci.
Dans le cas contraire, il y aurait désalignement des surfaces de l'arc du cintre. To this end, the adjustment is carried out jointly on the length by lengthening the latter and on the height by reducing the latter.
Otherwise, there will be misalignment of the surfaces of the arch of the hanger.

Le cintre selon l'invention et notamment le paletage est réalisé en tous matériaux adaptés présentant les qualités de résistance mécaniques requises et de résistance à l'humidité.
De préférence, le cintre selon l'invention est réalisé en métal inoxydable ou en aluminium mais il peut être également réalisé en tous matériaux synthétiques ou en une combinaison métal, matériaux synthétiques.The hanger according to the invention and in particular the pallet is made of all suitable materials having the qualities of mechanical resistance required and resistance to humidity.
Preferably, the hanger according to the invention is made of stainless metal or aluminum but it can also be made of all synthetic materials or a combination of metal and synthetic materials.

En figures 7, 8 et 9 est représenté un élément de coffrage pour le cintre selon l'invention, ledit élément de coffrage faisant également partie de l'invention.
Cet élément de coffrage est constitué par une tôle pliée, de préférence en métal, par exemple en aluminium en forme de «U» avec une paroi supérieure 12, deux flancs parallèles 13 et une ouverture inférieure 14.In Figures 7, 8 and 9 is shown a formwork element for the hanger according to the invention, said formwork element also forming part of the invention.
This formwork element consists of a folded sheet, preferably of metal, for example aluminum in the shape of a "U" with an upper wall 12, two parallel sides 13 and a lower opening 14.

Comme illustré aux figures 8/9, les flancs 13 du coffrage ont une hauteur supérieure aux flancs 2 du cintre.
Le coffrage s'emboíte sur le cintre et il est doté sur ses flancs de lumières 15 horizontales suivant une même ligne à travers lesquelles pénètrent des boulons horizontaux transversaux aux flancs 2 du cintre.
Le blocage en position s'obtient par des écrans à ailettes 16.As illustrated in Figures 8/9, the sides 13 of the formwork have a height greater than the sides 2 of the hanger.
The formwork fits on the hanger and it is provided on its sides with horizontal lights 15 along a same line through which penetrate horizontal bolts transverse to the sides 2 of the hanger.
Locking in position is obtained by fin screens 16.

La paroi supérieure 12 est dotée d'ouvertures 16 qui permet le coulage du béton après mise en place des éléments d'armature.
   Dans l'exemple de réalisation, le coffrage est représenté d'une seule longueur.
Cependant, dans le cadre de l'invention du cintre extensible, ledit coffrage est également conçu en au moins deux tronçons l'un coulissant dans l'autre pour en régler la longueur à celle du cintre.The upper wall 12 is provided with openings 16 which allows the concrete to be poured after the reinforcement elements have been placed.
In the exemplary embodiment, the formwork is shown of a single length.
However, in the context of the invention of the extendable hanger, said formwork is also designed in at least two sections, one sliding in the other to adjust the length to that of the hanger.
