Definitions

  • the present invention relates to the field of modular support frames for supporting slab formwork or the like, and more particularly concerns a secondary support beam, intended to be placed between two primary beams to form a modular support frame for supporting a formwork of slab or the like.
  • FIG. 1 An example of a modular support frame for supporting slab formwork or the like is illustrated in the figure 1 of the document FR 2 900 176 A1 .
  • Such a framework comprises primary beams carried by props. Between the primary beams are placed secondary support beams.
  • To form a slab or the like on top of the modular frame wooden plywood plates are placed on the upper carrying surfaces of the primary beams and secondary support beams. The concrete slab or similar is then poured onto the plywood sheets. After drying, the concrete slab or the like is self-supporting, so that the modular support frame can be removed.
  • the secondary support beam may include length adjustment means. These means make it possible to freely adjust the length of the secondary support beam to adapt it to a specific gap between two primary beams of a modular support frame to support a slab formwork or the like.

  • the secondary support beam P2X runs along the wall section M4 which is perpendicular to the wall section M1.
  • plywood plates are placed on the secondary support beams P2A to P2X and the primary beams P1A to P1D. These plywood plates cover the right triangle TR1 and the trapezoid TR2 resting only on the secondary support beams P2A to P2X and the primary beams P1A to P1D.
  • a problem proposed by the present invention is to make it possible to adapt in a simple and rapid manner a modular support framework, to support a slab formwork or the like, to the wall sections of a building forming between them angles different from 90° in order to better secure operators and effectively support the slab.
  • the present invention aims to provide a secondary support beam allowing more precise positioning than the beams of the prior art, to adapt even more precisely a modular support framework for slab formwork or the like to the angles formed between the sections of walls of a building, while effectively limiting the risks of rotation of the secondary support beam when an operator walks on it.
  • the invention proposes a secondary support beam according to claim 1.
  • the pivoting articulation of the first and second connection structures, combined with the adjustable length of the secondary support beam, makes it possible to arrange the secondary support beam according to the invention between two primary beams with an angle different from 90° between the primary beams and the secondary support beam.
  • the secondary support beam can thus be placed between the primary beams at an angle allowing it in particular to run along a section of wall forming an angle different from 90° relative to the primary beams.
  • the secondary support beam according to the invention can thus be arranged in the right triangle TR1 or in the trapezoid TR2 to support a plywood plate.
  • connection structures having different widths are particularly advantageous.
  • the width of the second connection structure can on the one hand be chosen sufficiently small so that the second connection structure can be arranged in the immediate vicinity of the section of wall to be extended and making an angle different from 90° with the primary beams between which the secondary support beam is placed.
  • the second connection structure can also be arranged in the immediate vicinity of the second connection structure of an adjacent secondary support beam, the two adjacent beams being arranged in a converging beam in the direction of their second end with the first longitudinal directions of the two beams adjacent not parallel to each other.
  • the width of the first connection structure can also be chosen sufficiently large so as to effectively limit the risks of rotation of the secondary support beam around the first longitudinal direction when an operator walks on the modular framework of support walks on the upper carrying surface of the secondary support beam.
  • the width of the first connection structure greater than the maximum width of the secondary support beam, makes it possible to effectively limit the risks of rotation of the secondary support beam around the first longitudinal direction when an operator walks on the framework modular support steps on the upper carrying surface of the secondary support beam.
  • the length adjustment means may comprise a first section and a second section extending respectively in second and third longitudinal directions and arranged to slide relative to each other in the first longitudinal direction by slide means to be movable between a folded position, in which the covering of a section by the the other is the largest, and at least one extended position, in which the covering of one section by the other is less than in the folded position.
  • the length adjustment means thus have a very simple, robust constitution, and can be easily and quickly used to adjust the length of the secondary support beam.
  • the first connection structure can extend equally in width on either side and away from the first direction of pivoting.
  • the risk of rotation of the secondary support beam around the first longitudinal direction is thus limited in the same way in both directions of rotation around the first longitudinal direction.

  • the distance between the adjacent secondary support beams will be maximum in the vicinity of their first connecting structures and will be a maximum of approximately 20 cm. Such a gap limits the risk that an operator could fall into the space between the two adjacent secondary support beams thus arranged.

  • the second connection structure can also be arranged even more closely in the immediate vicinity of the second connection structure of an adjacent secondary support beam, the two adjacent beams being arranged in a converging beam in the direction of their second ends with the first longitudinal directions not parallel to each other.
  • the first and second connection structures can pivot respectively around the first and second pivoting directions with an angular amplitude of approximately 80 degrees.

  • connection structures allow easy and rapid installation of the secondary support beam on the lateral structure receiving a primary beam or a prop by installation carried out in a simple movement. After this installation, the inhibition of any axial movement towards and away from the primary beam or the prop helps to keep the secondary support beam in place, which increases operator safety.

Description

La présente invention concerne le domaine des ossatures modulaires de soutien pour soutenir un coffrage de dalle ou analogue, et concerne plus particulièrement une poutrelle secondaire de soutien, destinée à être disposée entre deux poutres primaires pour former une ossature modulaire de soutien pour soutenir un coffrage de dalle ou analogue.The present invention relates to the field of modular support frames for supporting slab formwork or the like, and more particularly concerns a secondary support beam, intended to be placed between two primary beams to form a modular support frame for supporting a formwork of slab or the like.

Un exemple d'ossature modulaire de soutien pour soutenir un coffrage de dalle ou analogue est illustré sur la figure 1 du document FR 2 900 176 A1 . Une telle ossature comporte des poutres primaires portées par des étais. Entre les poutres primaires sont disposées des poutrelles secondaires de soutien. Pour coffrer une dalle ou analogue sur le dessus de l'ossature modulaire, on met en place des plaques de contreplaqué en bois sur les surfaces supérieures de portage des poutres primaires et des poutrelles secondaires de soutien. La dalle de béton ou analogue est ensuite coulée sur les plaques de contreplaqué. Après séchage, la dalle de béton ou analogue est autoportante, de sorte que l'ossature modulaire de soutien peut être retirée.An example of a modular support frame for supporting slab formwork or the like is illustrated in the figure 1 of the document FR 2 900 176 A1 . Such a framework comprises primary beams carried by props. Between the primary beams are placed secondary support beams. To form a slab or the like on top of the modular frame, wooden plywood plates are placed on the upper carrying surfaces of the primary beams and secondary support beams. The concrete slab or similar is then poured onto the plywood sheets. After drying, the concrete slab or the like is self-supporting, so that the modular support frame can be removed.

De façon connue, une poutrelle secondaire de soutien s'étend selon une première direction longitudinale entre une première extrémité et une deuxième extrémité, et comporte :

  • une surface supérieure de portage définissant un plan de portage, destinée à porter le coffrage de dalle ou analogue,
  • une première structure de raccordement, disposée à une extrémité libre du premier tronçon et adaptée pour venir se fixer à une poutre primaire respective ou à un étai,
  • une deuxième structure de raccordement, disposée à une extrémité libre du deuxième tronçon et adaptée pour venir se fixer à une poutre primaire respective ou à un étai.
In known manner, a secondary support beam extends in a first longitudinal direction between a first end and a second end, and comprises:
  • an upper carrying surface defining a carrying plane, intended to carry the slab formwork or the like,
  • a first connection structure, arranged at a free end of the first section and adapted to attach to a respective primary beam or to a prop,
  • a second connection structure, arranged at a free end of the second section and adapted to attach to a respective primary beam or to a prop.

Comme enseigné dans le document EP 2 754 778 A1 , la poutrelle secondaire de soutien peut comporter des moyens de réglage en longueur. Ces moyens permettent d'ajuster librement la longueur de la poutrelle secondaire de soutien pour l'adapter à un écart spécifique compris entre deux poutres primaires d'une ossature modulaire de soutien pour soutenir un coffrage de dalle ou analogue.As taught in the document EP 2 754 778 A1 , the secondary support beam may include length adjustment means. These means make it possible to freely adjust the length of the secondary support beam to adapt it to a specific gap between two primary beams of a modular support frame to support a slab formwork or the like.

Pour des raisons d'esthétisme architectural, de plus en plus de bâtiments ont des pans de mur qui présentent entre eux des angles différents de 90°, comme illustré sur la figure 1. En l'espèce, le pan de mur M1 forme un angle A1 supérieur à 90° avec le pan de mur M2. Le pan de mur M2 forme un angle A2 supérieur à 90° avec le pan de mur M3. Le pan de mur M3 se raccorde à un pan de mur M4 selon un angle A3 supérieur à 90°. Le pan de mur M4 forme quant à lui un angle A4 de 90° avec le pan de mur M1.For reasons of architectural aesthetics, more and more buildings have sections of wall which have angles between them different from 90°, as illustrated in the figure 1 . In this case, the wall section M1 forms an angle A1 greater than 90° with the wall section M2. The wall section M2 forms an angle A2 greater than 90° with the wall section M3. The M3 wall section connects to a section of M4 wall at an angle A3 greater than 90°. The M4 wall section forms an angle A4 of 90° with the M1 wall section.

Lorsqu'une ossature modulaire de soutien OMS pour soutenir un coffrage de dalle ou analogue est mise en place, comme illustré sur la figure 1, les poutrelles secondaires de soutien P2A à P2X sont disposées perpendiculairement aux poutres primaires P1A à P1D qui sont parallèles au pan de mur M1. Il en résulte qu'il subsiste un triangle rectangle TR1 vide entre le pan de mur M2, la poutre primaire P1B et la poutrelle secondaire de soutien P2F. Et il subsiste un trapèze TR2 vide entre le pan de mur M3, la poutrelle secondaire de soutien P2L et les poutres primaires P1B et P1C. La poutrelle secondaire de soutien P2X longe quant à elle le pan de mur M4 qui est perpendiculaire au pan de mur M1. Pour couler la dalle, des plaques de contreplaqué sont disposées sur les poutrelles secondaires de soutien P2A à P2X et les poutres primaires P1A à P1D. Ces plaques de contreplaqué viennent recouvrir le triangle rectangle TR1 et le trapèze TR2 en reposant seulement sur les poutrelles secondaires de soutien P2A à P2X et les poutres primaires P1A à P1D.When a modular OMS support frame to support slab formwork or the like is installed, as illustrated in figure 1 , the secondary support beams P2A to P2X are arranged perpendicular to the primary beams P1A to P1D which are parallel to the wall section M1. As a result, there remains an empty right triangle TR1 between the wall section M2, the primary beam P1B and the secondary support beam P2F. And there remains an empty trapezoid TR2 between the wall section M3, the secondary support beam P2L and the primary beams P1B and P1C. The secondary support beam P2X runs along the wall section M4 which is perpendicular to the wall section M1. To pour the slab, plywood plates are placed on the secondary support beams P2A to P2X and the primary beams P1A to P1D. These plywood plates cover the right triangle TR1 and the trapezoid TR2 resting only on the secondary support beams P2A to P2X and the primary beams P1A to P1D.

L'absence de poutrelle secondaire de soutien dans le triangle rectangle TR1 et dans le trapèze TR2 constitue un danger pour un utilisateur déambulant sur les plaques de contreplaqué, celui-ci pouvant accidentellement passer à travers l'ossature modulaire de soutien OMS (à travers le triangle rectangle TR1 ou à travers le trapèze TR2). L'absence de soutien nuit également à la solidité du coffrage pour supporter la dalle avant prise du béton.The absence of a secondary support beam in the right triangle TR1 and in the trapezoid TR2 constitutes a danger for a user walking on the plywood plates, who may accidentally pass through the modular OMS support frame (through the right triangle TR1 or through the trapezoid TR2). The lack of support also affects the strength of the formwork to support the slab before the concrete sets.

Les documents JP H05-12544 U et CN 2 649 697 Y décrivent des poutrelles secondaires de soutien selon le préambule de la revendication 1, comportant des première et deuxième structures de raccordement pivotantes s'étendant en largeur selon une même distance.The documents JP H05-12544 U And CN 2 649 697 Y describe secondary support beams according to the preamble of claim 1, comprising first and second pivoting connection structures extending in width at the same distance.

Un problème proposé par la présente invention est de permettre d'adapter de façon simple et rapide une ossature modulaire de soutien, pour soutenir un coffrage de dalle ou analogue, aux pans de murs d'un bâtiment formant entre eux des angles différents de 90° afin de mieux sécuriser les opérateurs et de supporter efficacement la dalle.A problem proposed by the present invention is to make it possible to adapt in a simple and rapid manner a modular support framework, to support a slab formwork or the like, to the wall sections of a building forming between them angles different from 90° in order to better secure operators and effectively support the slab.

Simultanément, la présente invention vise à fournir une poutrelle secondaire de soutien permettant un positionnement plus précis que les poutrelles de l'art antérieur, pour adapter de façon plus précise encore une ossature modulaire de soutien pour coffrage de dalle ou analogue aux angles formés entre les pans de murs d'un bâtiment, tout en limitant efficacement les risques de rotation de la poutrelle secondaire de soutien lorsqu'un opérateur marche dessus.Simultaneously, the present invention aims to provide a secondary support beam allowing more precise positioning than the beams of the prior art, to adapt even more precisely a modular support framework for slab formwork or the like to the angles formed between the sections of walls of a building, while effectively limiting the risks of rotation of the secondary support beam when an operator walks on it.

Pour atteindre ces objets ainsi que d'autres, l'invention propose une poutrelle secondaire de soutien selon la revendication 1.To achieve these objects as well as others, the invention proposes a secondary support beam according to claim 1.

L'articulation à pivotement des première et deuxième structures de raccordement, combinée à la longueur ajustable de la poutrelle secondaire de soutien, permet de venir disposer la poutrelle secondaire de soutien selon l'invention entre deux poutres primaires avec un angle différent de 90° entre les poutres primaires et la poutrelle secondaire de soutien. La poutrelle secondaire de soutien peut ainsi être disposée entre les poutres primaires avec un angle lui permettant notamment de longer un pan de mur formant un angle différent de 90° par rapport aux poutres primaires. La poutrelle secondaire de soutien selon l'invention peut ainsi être disposée dans le triangle rectangle TR1 ou dans le trapèze TR2 pour venir soutenir une plaque de contreplaqué.The pivoting articulation of the first and second connection structures, combined with the adjustable length of the secondary support beam, makes it possible to arrange the secondary support beam according to the invention between two primary beams with an angle different from 90° between the primary beams and the secondary support beam. The secondary support beam can thus be placed between the primary beams at an angle allowing it in particular to run along a section of wall forming an angle different from 90° relative to the primary beams. The secondary support beam according to the invention can thus be arranged in the right triangle TR1 or in the trapezoid TR2 to support a plywood plate.

Le fait de disposer de deux structures de raccordement ayant des largeurs différentes est tout particulièrement avantageux.The fact of having two connection structures having different widths is particularly advantageous.

En effet, la largeur de la deuxième structure de raccordement peut d'une part être choisie suffisamment petite de façon que la deuxième structure de raccordement puisse être disposée à proximité immédiate du pan de mur à longer et faisant un angle différent de 90° avec les poutres primaires entre lesquelles est disposée la poutrelle secondaire de soutien. La deuxième structure de raccordement peut également être disposée à proximité immédiate de la deuxième structure de raccordement d'une poutrelle secondaire de soutien adjacente, les deux poutrelles adjacentes étant disposées en faisceau convergent en direction de leur deuxième extrémité avec les premières directions longitudinales des deux poutrelles adjacentes non parallèles entre elles.Indeed, the width of the second connection structure can on the one hand be chosen sufficiently small so that the second connection structure can be arranged in the immediate vicinity of the section of wall to be extended and making an angle different from 90° with the primary beams between which the secondary support beam is placed. The second connection structure can also be arranged in the immediate vicinity of the second connection structure of an adjacent secondary support beam, the two adjacent beams being arranged in a converging beam in the direction of their second end with the first longitudinal directions of the two beams adjacent not parallel to each other.

Et la largeur de la première structure de raccordement peut d'autre part être choisie suffisamment grande de façon à limiter efficacement les risques de rotation de la poutrelle secondaire de soutien autour de la première direction longitudinale lorsqu'un opérateur déambulant sur l'ossature modulaire de soutien marche sur la surface supérieure de portage de la poutrelle secondaire de soutien.And the width of the first connection structure can also be chosen sufficiently large so as to effectively limit the risks of rotation of the secondary support beam around the first longitudinal direction when an operator walks on the modular framework of support walks on the upper carrying surface of the secondary support beam.

La largeur de la première structure de raccordement, supérieure à la largeur maximale de la poutrelle secondaire de soutien, permet de limiter efficacement les risques de rotation de la poutrelle secondaire de soutien autour de la première direction longitudinale lorsqu'un opérateur déambulant sur l'ossature modulaire de soutien marche sur la surface supérieure de portage de la poutrelle secondaire de soutien.The width of the first connection structure, greater than the maximum width of the secondary support beam, makes it possible to effectively limit the risks of rotation of the secondary support beam around the first longitudinal direction when an operator walks on the framework modular support steps on the upper carrying surface of the secondary support beam.

Avantageusement, les moyens de réglage en longueur peuvent comprendre un premier tronçon et un deuxième tronçon s'étendant respectivement selon des deuxième et troisième directions longitudinales et disposés à coulissement l'un par rapport à l'autre selon la première direction longitudinale par des moyens de glissière pour être déplaçables entre une position de repli, dans laquelle le recouvrement d'un tronçon par l'autre est le plus grand, et au moins une position d'extension, dans laquelle le recouvrement d'un tronçon par l'autre est moindre qu'en position de repli.Advantageously, the length adjustment means may comprise a first section and a second section extending respectively in second and third longitudinal directions and arranged to slide relative to each other in the first longitudinal direction by slide means to be movable between a folded position, in which the covering of a section by the the other is the largest, and at least one extended position, in which the covering of one section by the other is less than in the folded position.

Les moyens de réglage en longueur ont ainsi une constitution très simple, robuste, et peuvent être facilement et rapidement mis en oeuvre pour ajuster la longueur de la poutrelle secondaire de soutien.The length adjustment means thus have a very simple, robust constitution, and can be easily and quickly used to adjust the length of the secondary support beam.

Avantageusement, la première structure de raccordement peut s'étendre en largeur de façon égale de part et d'autre et à l'écart de la première direction de pivotement. Le risque de rotation de la poutrelle secondaire de soutien autour de la première direction longitudinale est ainsi limité de façon identique dans les deux sens de rotation autour de la première direction longitudinale.Advantageously, the first connection structure can extend equally in width on either side and away from the first direction of pivoting. The risk of rotation of the secondary support beam around the first longitudinal direction is thus limited in the same way in both directions of rotation around the first longitudinal direction.

De préférence, lorsque la direction transversale selon laquelle s'étend en largeur la première structure de raccordement est perpendiculaire à la première direction longitudinale, la première structure de raccordement peut s'étendre en largeur à l'écart de la première direction de pivotement et au-delà de la largeur maximale de la poutrelle secondaire de soutien, dans au moins un sens, selon une distance maximale d'environ 10 cm.Preferably, when the transverse direction in which the first connection structure extends in width is perpendicular to the first longitudinal direction, the first connection structure can extend in width away from the first direction of pivoting and at -beyond the maximum width of the secondary support beam, in at least one direction, over a maximum distance of approximately 10 cm.

Ainsi, lorsque deux poutrelles secondaires de soutien sont disposées de façon adjacente avec leur première structure de raccordement en appui l'une contre l'autre et que les premières directions longitudinales des deux poutrelles secondaires de soutien convergent en direction de leur deuxième structure de raccordement ou sont parallèles, l'écart entre les poutrelles secondaires de soutien adjacentes sera maximal au voisinage de leurs premières structures de raccordement et sera d'au maximum environ 20 cm. Un tel écart limite les risques qu'un opérateur puisse tomber dans l'espace compris entre les deux poutrelles secondaires de soutien adjacentes ainsi disposées.Thus, when two secondary support beams are arranged adjacently with their first connection structure bearing against each other and the first longitudinal directions of the two secondary support beams converge towards their second connection structure or are parallel, the distance between the adjacent secondary support beams will be maximum in the vicinity of their first connecting structures and will be a maximum of approximately 20 cm. Such a gap limits the risk that an operator could fall into the space between the two adjacent secondary support beams thus arranged.

Avantageusement, on peut prévoir que :

  • la poutrelle secondaire de soutien comporte une section transversale maximale définie par une hauteur selon la première ou la deuxième direction de pivotement, et définie par une largeur selon une direction transversale perpendiculaire aux directions de pivotement,
  • la deuxième structure de raccordement s'étend en largeur, selon une direction transversale perpendiculaire à la première direction longitudinale et à la deuxième direction de pivotement, selon une distance inférieure ou égale à la largeur maximale de la poutrelle secondaire de soutien.
Advantageously, we can predict that:
  • the secondary support beam has a maximum cross section defined by a height according to the first or second direction of pivoting, and defined by a width according to a transverse direction perpendicular to the directions of pivoting,
  • the second connection structure extends in width, in a transverse direction perpendicular to the first longitudinal direction and to the second direction of pivoting, according to a distance less than or equal to the maximum width of the secondary support beam.

La deuxième structure de raccordement peut ainsi être disposée encore plus à proximité immédiate du pan de mur à longer et faisant un angle différent de 90° avec les poutres primaires entre lesquelles est disposée la poutrelle secondaire de soutien. La deuxième structure de raccordement peut également être disposée encore plus à proximité immédiate de la deuxième structure de raccordement d'une poutrelle secondaire de soutien adjacente, les deux poutrelles adjacentes étant disposées en faisceau convergent en direction de leurs deuxièmes extrémités avec les premières directions longitudinales non parallèles entre elles.The second connection structure can thus be placed even closer in the immediate vicinity of the section of wall to be extended and making an angle different from 90° with the primary beams between which the secondary support beam is arranged. The second connection structure can also be arranged even more closely in the immediate vicinity of the second connection structure of an adjacent secondary support beam, the two adjacent beams being arranged in a converging beam in the direction of their second ends with the first longitudinal directions not parallel to each other.

De préférence, les première et deuxième structures de raccordement peuvent pivoter respectivement autour des première et deuxième directions de pivotement selon une amplitude angulaire d'environ 80 degrés. Une telle amplitude de pivotement permet à la poutrelle secondaire de soutien de s'adapter à la majorité des angles que peut former un pan de mur avec les deux poutres primaires entre lesquelles est disposée la poutrelle secondaire de soutien.Preferably, the first and second connection structures can pivot respectively around the first and second pivoting directions with an angular amplitude of approximately 80 degrees. Such an amplitude of pivoting allows the secondary support beam to adapt to the majority of angles that a section of wall can form with the two primary beams between which the secondary support beam is arranged.

Avantageusement, chaque structure de raccordement peut comporter une structure inférieure de crochetage conformée pour venir en appui vertical par simple déplacement vers le bas sur une structure latérale de réception d'une poutre primaire ou d'un étai selon une zone d'appui vertical, et pour s'accrocher à la structure latérale de réception de façon à s'opposer à tout déplacement axial vers et à l'écart de la poutre primaire ou de l'étai.Advantageously, each connection structure can include a lower hooking structure shaped to come into vertical support by simple downward movement on a lateral structure for receiving a primary beam or a prop according to a vertical support zone, and to hook onto the receiving side structure so as to oppose any axial movement towards and away from the primary beam or prop.

De telles structures de raccordement permettent une mise en place facile et rapide de la poutrelle secondaire de soutien sur la structure latérale de réception d'une poutre primaire ou d'un étai par un posage s'effectuant selon un mouvement simple. Après cette mise en place, l'inhibition de tout déplacement axial vers et à l'écart de la poutre primaire ou de l'étai contribue à maintenir en bonne place la poutrelle secondaire de soutien, ce qui accroît la sécurité des opérateurs.Such connection structures allow easy and rapid installation of the secondary support beam on the lateral structure receiving a primary beam or a prop by installation carried out in a simple movement. After this installation, the inhibition of any axial movement towards and away from the primary beam or the prop helps to keep the secondary support beam in place, which increases operator safety.

Selon un autre aspect de l'invention, il est proposé une ossature modulaire de soutien pour coffrage de dalle ou analogue, comportant :

  • au moins une poutre primaire de soutien munie sur ses côtés de structures latérales de réception d'une structure de raccordement d'une poutrelle secondaire de soutien telle que décrite précédemment, et/ou au moins un étai muni d'une structure latérale de réception d'une structure de raccordement d'une poutrelle secondaire de soutien telle que décrite précédemment,
  • au moins une poutrelle secondaire de soutien telle que décrite précédemment.
According to another aspect of the invention, a modular support framework is proposed for slab formwork or the like, comprising:
  • at least one primary support beam provided on its sides with lateral structures for receiving a connection structure for a secondary support beam as described above, and/or at least one prop provided with a lateral structure for receiving 'a connection structure for a secondary support beam as described previously,
  • at least one secondary support beam as described previously.

Sur les figures 2 à 7 est illustré un mode de réalisation particulier de poutrelle secondaire de soutien 1 selon l'invention. Cette poutrelle secondaire de soutien est destinée à être disposée entre deux poutres primaires P1A, P1B ou P1C (figure 1) pour former une ossature modulaire de soutien pour soutenir un coffrage de dalle ou analogue. La poutrelle secondaire de soutien 1 s'étend selon une première direction longitudinale I-I entre une première extrémité 2 et une deuxième extrémité 3. La poutrelle secondaire de soutien 1 comporte une surface supérieure de portage 4 définissant un plan de portage PP, destinée à porter le coffrage de dalle ou analogue.On the figures 2 to 7 a particular embodiment of secondary support beam 1 according to the invention is illustrated. This secondary support beam is intended to be placed between two primary beams P1A, P1B or P1C ( figure 1 ) to form a modular support framework for supporting slab formwork or the like. The secondary support beam 1 extends in a first longitudinal direction II between a first end 2 and a second end 3. The secondary support beam 1 comprises an upper carrying surface 4 defining a carrying plane PP, intended to carry the slab formwork or the like.

Des moyens de réglage 5 permettent de régler la longueur L de la poutrelle secondaire de soutien 1, faisant ainsi varier la distance séparant les première et deuxième extrémités 2 et 3. En l'espèce, les moyens de réglage 5 comprennent un premier tronçon 6 et un deuxième tronçon 7 s'étendant respectivement selon des deuxième et troisième directions longitudinales II-II et III-III. Les premier et deuxième tronçons 6 et 7 sont disposés à coulissement l'un par rapport à l'autre selon la première direction longitudinale I-I (qui coïncide avec les deuxième et troisième directions longitudinales II-II et III-III) par des moyens de glissière 8 pour être déplaçables entre une position de repli (figure 6), dans laquelle le recouvrement R du premier tronçon 6 par le deuxième tronçon 7 est le plus grand, et au moins une position d'extension (figure 2), dans laquelle le recouvrement R du premier tronçon 6 par le deuxième tronçon 7 est moindre qu'en position de repli.Adjustment means 5 make it possible to adjust the length L of the secondary support beam 1, thus varying the distance separating the first and second ends 2 and 3. In this case, the adjustment means 5 comprise a first section 6 and a second section 7 extending respectively in second and third longitudinal directions II-II and III-III. The first and second sections 6 and 7 are arranged to slide one relative to the other in the first longitudinal direction II (which coincides with the second and third longitudinal directions II-II and III-III) by slide means 8 to be movable between a folded position ( Figure 6 ), in which the overlap R of the first section 6 by the second section 7 is the greatest, and at least one extension position ( figure 2 ), in which the coverage R of the first section 6 by the second section 7 is less than in the folded position.

Les surfaces supérieures 6b et 7b des premier et deuxième tronçons 6 et 7 (définissant la surface supérieure de portage 4) sont comprises dans le même et unique plan de portage PP de façon que le coffrage de dalle ou analogue soit porté par les premier et deuxième tronçons 6 et 7 à une seule et même hauteur par rapport au sol.The upper surfaces 6b and 7b of the first and second sections 6 and 7 (defining the upper carrying surface 4) are included in the same and single carrying plane PP so that the slab formwork or the like is carried by the first and second sections 6 and 7 at the same height relative to the ground.

Une première structure de raccordement 9 est disposée à la première extrémité 2 et est adaptée pour venir se fixer à une poutre primaire respective ou à un étai. La première extrémité 2 de la poutrelle secondaire de soutien 1 est constituée par une première extrémité 6a du premier tronçon 6.A first connection structure 9 is arranged at the first end 2 and is adapted to attach to a respective primary beam or to a prop. The first end 2 of the secondary support beam 1 is constituted by a first end 6a of the first section 6.

Une deuxième structure de raccordement 10 est disposée à la deuxième extrémité 3 et est adaptée pour venir se fixer à une poutre primaire respective ou à un étai. La deuxième extrémité 3 de la poutrelle secondaire de soutien 1 est constituée par une extrémité 7a du deuxième tronçon 7.A second connection structure 10 is arranged at the second end 3 and is adapted to attach to a respective primary beam or to a prop. The second end 3 of the secondary support beam 1 is constituted by an end 7a of the second section 7.

Comme on le voit plus particulièrement sur la figure 3, la première structure de raccordement 9 est articulée sur la première extrémité 2 par l'intermédiaire d'une liaison pivot 11 autorisant un pivotement de la première structure de raccordement 9 autour d'une première direction de pivotement IV-IV perpendiculaire au plan de portage PP. Et on voit plus particulièrement sur la figure 4 que la deuxième structure de raccordement 10 est articulée sur la deuxième extrémité 3 par l'intermédiaire d'une liaison pivot 12 autorisant un pivotement de la deuxième structure de raccordement 10 autour d'une deuxième direction de pivotement V-V perpendiculaire au plan de portage PP.As we see more particularly on the Figure 3 , the first connection structure 9 is articulated on the first end 2 via a pivot connection 11 authorizing pivoting of the first connection structure 9 around a first pivoting direction IV-IV perpendicular to the carrying plane PP. And we see more particularly on the figure 4 that the second connection structure 10 is articulated on the second end 3 via a pivot connection 12 authorizing pivoting of the second connection structure 10 around a second pivoting direction VV perpendicular to the carrying plane PP.

Les surfaces supérieures 9b et 10b des première et deuxième structures de raccordement 9 et 10 sont situées en hauteur, selon les directions de pivotement IV-IV ou V-V, à des hauteurs inférieures ou égales à celle du plan de portage PP. Ici, les surfaces supérieures 9b et 10b sont comprises dans le plan de portage PP pour contribuer à soutenir le coffrage de dalle ou analogue à une seule et même hauteur par rapport au sol.The upper surfaces 9b and 10b of the first and second connection structures 9 and 10 are located in height, according to the pivoting directions IV-IV or V-V, at heights less than or equal to that of the carrying plane PP. Here, the upper surfaces 9b and 10b are included in the carrying plane PP to help support the slab formwork or the like at a single height relative to the ground.

On voit plus particulièrement sur les figures 2 et 3 que la poutrelle secondaire de soutien 1 comporte une section transversale maximale définie par une hauteur H selon la première IV-IV ou la deuxième V-V direction de pivotement, et est définie par une largeur L1 selon une direction transversale VI-VI perpendiculaire aux directions de pivotement IV-IV et V-V.We see more particularly on the figures 2 And 3 that the secondary support beam 1 has a maximum cross section defined by a height H according to the first IV-IV or the second VV pivoting direction, and is defined by a width L1 according to a transverse direction VI-VI perpendicular to the pivoting directions IV-IV and VV.

Sur la figure 6, on voit que la première structure de raccordement 9 s'étend en largeur, selon la direction transversale VI-VI perpendiculaire à la première direction longitudinale I-I et à la première direction de pivotement IV-IV, selon une distance L2 supérieure à la largeur L1 maximale de la poutrelle secondaire de soutien 1.On the Figure 6 , we see that the first connection structure 9 extends in width, in the transverse direction VI-VI perpendicular to the first longitudinal direction II and to the first pivoting direction IV-IV, according to a distance L2 greater than the width L1 maximum of the secondary support beam 1.

De façon plus précise, la première structure de raccordement 9 s'étend en largeur de façon égale de part et d'autre et à l'écart de la première direction de pivotement IV-IV. Lorsque la première structure de raccordement 9 s'étend en largeur selon la direction transversale VI-VI perpendiculaire à la première direction longitudinale I-I et à la première direction de pivotement IV-IV, elle s'étend en largeur à l'écart de la première direction de pivotement IV-IV, et au-delà de la largeur L1 maximale de la poutrelle secondaire de soutien 1, dans les deux sens, selon une distance D2 maximale d'environ 10 cm. Dans le mode de réalisation illustré sur les figures 2 à 7, la poutrelle secondaire de soutien 1 a une largeur L1 de 10 cm et la première structure de raccordement 9 a une largeur L2 de 30 cm (15 cm de part et d'autre du plan défini par la première direction longitudinale I-I et les première et deuxième directions de pivotement IV-IV et V-V).More precisely, the first connection structure 9 extends in width equally on both sides and away from the first pivoting direction IV-IV. When the first connection structure 9 extends in width in the transverse direction VI-VI perpendicular to the first longitudinal direction II and the first pivoting direction IV-IV, it extends in width away from the first pivoting direction IV-IV, and beyond the maximum width L1 of the secondary support beam 1, in both directions, at a maximum distance D2 of approximately 10 cm. In the embodiment illustrated on the figures 2 to 7 , the secondary support beam 1 has a width L1 of 10 cm and the first connection structure 9 has a width L2 of 30 cm (15 cm on either side of the plane defined by the first longitudinal direction II and the first and second pivot directions IV-IV and VV).

Sur cette même figure 6, on voit que la deuxième structure de raccordement 10 s'étend en largeur, selon une direction transversale VII-VII perpendiculaire à la première direction longitudinale I-I et à la deuxième direction de pivotement V-V selon une distance L3 inférieure à la largeur L2 de la première structure de raccordement 9, et même inférieure ou égale à la largeur L1 maximale de la poutrelle secondaire de soutien 1. En l'espèce, la deuxième structure de raccordement 10 a une largeur L3 de 5 cm (la deuxième structure de raccordement 10 s'étend en largeur selon la distance D1 de 2,5 cm de part et d'autre du plan défini par la première direction longitudinale I-I et les première et deuxième directions de pivotement IV-IV et V-V).On this same Figure 6 , we see that the second connection structure 10 extends in width, in a transverse direction VII-VII perpendicular to the first longitudinal direction II and to the second pivoting direction VV at a distance L3 less than the width L2 of the first connection structure 9, and even less than or equal to the maximum width L1 of the secondary support beam 1. In this case, the second connection structure 10 has a width L3 of 5 cm (the second connection structure 10 is extends in width according to the distance D1 of 2.5 cm on either side of the plane defined by the first longitudinal direction II and the first and second pivoting directions IV-IV and VV).

Les première et deuxième structures de raccordement 9 et 10 pivotent respectivement autour des première et deuxième directions de pivotement IV-IV et V-V selon des amplitudes angulaires A5 et A6 d'environ 80° (environ 40° de part et d'autre du plan défini par la première direction longitudinale I-I et les première et deuxième directions de pivotement IV-IV et V-V).The first and second connection structures 9 and 10 pivot respectively around the first and second pivoting directions IV-IV and V-V according to angular amplitudes A5 and A6 of approximately 80° (approximately 40° on either side of the defined plane by the first longitudinal direction I-I and the first and second pivoting directions IV-IV and V-V).

On voit plus particulièrement sur les figures 3 et 4 que les première et deuxième structures de raccordement 9 et 10 comportent chacune une structure inférieure de crochetage 13 conformée pour venir en appui vertical par simple déplacement vers le bas sur une structure latérale de réception 14 d'une poutre primaire P1A, P1B, P1C ou P1D ou sur une structure latérale de réception 15 d'un étai E1, E2, E3, E4, E5, E6, E7 ou E8 selon une zone d'appui verticale, et pour s'accrocher à la structure latérale de réception 14 ou 15 de façon à s'opposer à tout déplacement axial vers et à l'écart de la poutre primaire P1A, P1B, P1C ou P1D ou de l'étai E1, E2, E3, E4, E5, E6, E7 ou E8 (figure 7). A noter que, bien que présentant des formes différentes, les structures latérales de réception 14 et 15 permettent de recevoir en appui la structure inférieure de crochetage 13 des première et deuxième structures de raccordement 9 et 10 d'une même façon, c'est-à-dire avec le plan de portage PP de la poutrelle secondaire de soutien 1 sensiblement coplanaire avec le plan de portage PP1 de la poutre primaire P1A, P1B, P1C ou P1D et de l'étai E1, E2, E3, E4, E5, E6, E7 ou E8. Ainsi, les première et deuxième structures de raccordement 9 et 10 peuvent venir en appui vertical sur la structure latérale de réception 14 et/ou sur la structure latérale de réception 15.We see more particularly on the figures 3 And 4 that the first and second connection structures 9 and 10 each comprise a structure lower hook 13 shaped to come into vertical support by simple downward movement on a lateral receiving structure 14 of a primary beam P1A, P1B, P1C or P1D or on a lateral receiving structure 15 of a prop E1, E2 , E3, E4, E5, E6, E7 or E8 according to a vertical support zone, and to attach to the lateral receiving structure 14 or 15 so as to oppose any axial movement towards and away of the primary beam P1A, P1B, P1C or P1D or of the prop E1, E2, E3, E4, E5, E6, E7 or E8 ( Figure 7 ). Note that, although having different shapes, the lateral receiving structures 14 and 15 make it possible to receive in support the lower hooking structure 13 of the first and second connection structures 9 and 10 in the same way, that is to say, that is to say with the carrying plane PP of the secondary support beam 1 substantially coplanar with the carrying plane PP1 of the primary beam P1A, P1B, P1C or P1D and of the prop E1, E2, E3, E4, E5, E6, E7 or E8. Thus, the first and second connection structures 9 and 10 can come into vertical support on the lateral receiving structure 14 and/or on the lateral receiving structure 15.

Lors de l'utilisation de la poutrelle secondaire de soutien 1, celle-ci se présente tout d'abord avec ses premier et deuxième tronçons 6 et 7 en position de repli (figure 6), position dans laquelle elle est stockée de façon compacte. La structure inférieure de crochetage 13 de la première ou de la deuxième structure de raccordement 9 ou 10 est ensuite amenée en appui vertical sur une structure latérale de réception 14 de poutre primaire P1A-P1D et/ou sur une structure latérale de réception 15 d'étai E1-E8. La structure inférieure de crochetage 13 de l'autre de la première ou de la deuxième structure de raccordement 9 ou 10 est ensuite amenée en appui vertical sur une autre structure latérale de réception 14 de poutre primaire P1A-P1D et/ou structure latérale de réception 15 d'étai E1-E8. Pour ce faire, la longueur L de la poutrelle secondaire de soutien 1 peut être ajustée en faisant coulisser les premier et deuxième tronçons 6 et 7 vers une position d'extension.When using the secondary support beam 1, it is first presented with its first and second sections 6 and 7 in the folded position ( Figure 6 ), position in which it is stored compactly. The lower hooking structure 13 of the first or second connection structure 9 or 10 is then brought into vertical support on a lateral receiving structure 14 of primary beam P1A-P1D and/or on a lateral receiving structure 15 of prop E1-E8. The lower hooking structure 13 of the other of the first or second connection structure 9 or 10 is then brought into vertical support on another lateral receiving structure 14 of primary beam P1A-P1D and/or lateral receiving structure 15 of stay E1-E8. To do this, the length L of the secondary support beam 1 can be adjusted by sliding the first and second sections 6 and 7 towards an extension position.

Lors de la mise en place des première et deuxième structures de raccordement 9 et 10, il peut être nécessaire d'orienter la première direction longitudinale I-I de la poutrelle secondaire de soutien 1 selon un angle différent de 90° avec les directions d'allongement des poutres primaires P1A-P1D sur lesquelles repose la poutrelle secondaire de soutien 1. Pour ce faire, les première et deuxième structures de raccordement 9 et 10 sont pivotées, grâce aux liaisons pivot 11 et 12, autour des directions de pivotement IV-IV et V-V.When installing the first and second connection structures 9 and 10, it may be necessary to orient the first longitudinal direction I-I of the secondary support beam 1 at an angle different from 90° with the directions of elongation of the primary beams P1A-P1D on which the secondary support beam 1 rests. To do this, the first and second connecting structures 9 and 10 are pivoted, thanks to the pivot connections 11 and 12, around the pivoting directions IV-IV and V-V .

Sur les figures 8 et 9 est illustrée l'ossature modulaire de soutien OMS de la figure 1 comprenant quatre poutres primaires de soutien P1A à P1D munies sur leur côté, comme sur la figure 7, de structures latérales de réception 14 d'une première ou d'une deuxième structure de raccordement 9 ou 10. Les poutres primaires de soutien P1A à P1D sont soutenues par des étais E1 à E8 également munis, comme sur la figure 7, de structures latérales de réception 15 d'une première ou deuxième structure de raccordement 9 ou 10.On the figures 8 And 9 is illustrated the modular OMS support framework of the figure 1 comprising four primary support beams P1A to P1D equipped on their side, as on the Figure 7 , lateral reception structures 14 of a first or second connection structure 9 or 10. The primary support beams P1A to P1D are supported by props E1 to E8 also provided, as on the Figure 7 , lateral receiving structures 15 of a first or second connection structure 9 or 10.

On voit plus particulièrement sur les figures 8 et 9 que le triangle rectangle TR1 a été comblé par une poutrelle secondaire de soutien 1A similaire à la poutrelle de soutien 1 des figures 2 à 7. La poutrelle secondaire de soutien 1A repose selon sa deuxième structure de raccordement 10 sur l'étai E2 et repose selon sa première structure de raccordement 9 sur la poutre primaire P1B et sur l'étai E4.We see more particularly on the figures 8 And 9 that the right triangle TR1 was filled by a secondary support beam 1A similar to the support beam 1 of the figures 2 to 7 . The secondary support beam 1A rests according to its second connection structure 10 on the prop E2 and rests according to its first connection structure 9 on the primary beam P1B and on the prop E4.

Le trapèze TR2 a lui aussi été comblé par un groupe de poutrelles secondaires de soutien 1B, 1C, 1D et 1E similaires à la poutrelle secondaire de soutien 1 illustrée sur les figures 2 à 7. Les poutrelles secondaires de soutien 1B à 1E sont disposées en faisceau et convergent au niveau de leur deuxième extrémité 3. Les poutrelles secondaires de soutien 1B et 1C reposent selon leur deuxième structure de raccordement 10 sur la poutre primaire de soutien P1B, tandis que les poutrelles secondaires de soutien 1D et 1E reposent selon leur deuxième structure de raccordement 10 sur l'étai E4. Les poutrelles secondaires de soutien 1B, 1C et 1D reposent en appui selon leur première structure de raccordement 9 sur la poutre primaire de soutien P1C tandis que la poutrelle secondaire de soutien 1E repose selon sa première structure de raccordement 9 simultanément sur la poutre primaire de soutien P1C et sur l'étai E6.The trapezoid TR2 was also filled by a group of secondary support beams 1B, 1C, 1D and 1E similar to the secondary support beam 1 illustrated on the figures 2 to 7 . The secondary support beams 1B to 1E are arranged in a bundle and converge at their second end 3. The secondary support beams 1B and 1C rest according to their second connection structure 10 on the primary support beam P1B, while the beams secondary support 1D and 1E rest according to their second connection structure 10 on the prop E4. The secondary support beams 1B, 1C and 1D rest in support according to their first connection structure 9 on the primary support beam P1C while the secondary support beam 1E rests according to its first connection structure 9 simultaneously on the primary support beam P1C and on the E6 stay.

On voit plus particulièrement sur la figure 9 que les premières structures de raccordement 10 des poutrelles secondaires de soutien 1B à 1E sont en contact les unes à la suite des autres. Du fait de la largeur L2 des premières structures de raccordement 9 par rapport à la largeur L1 des poutrelles secondaires de soutien 1B à 1E, l'écart entre les poutrelles secondaires adjacentes 1B et 1C, ou 1C et 1D, ou 1D et 1E (pris perpendiculairement à la première direction longitudinale I-I de l'une ou l'autre des poutrelles adjacentes 1B ou 1C, 1C ou 1D, 1D ou 1E) sera maximal au voisinage des premières structures de raccordement 9 et sera d'au maximum environ 20 cm. Les espaces intercalaires E1, E2 et E3 entre les poutrelles secondaires de soutien 1B, 1C, 1D et 1E sont ainsi dimensionnés de façon à limiter efficacement les risques qu'un opérateur passe à travers l'ossature modulaire de soutien OMS.We see more particularly on the Figure 9 that the first connection structures 10 of the secondary support beams 1B to 1E are in contact one after the other. Due to the width L2 of the first connection structures 9 relative to the width L1 of the secondary support beams 1B to 1E, the distance between the adjacent secondary beams 1B and 1C, or 1C and 1D, or 1D and 1E (taken perpendicular to the first longitudinal direction II of one or the other of the adjacent beams 1B or 1C, 1C or 1D, 1D or 1E) will be maximum in the vicinity of the first connection structures 9 and will be at most approximately 20 cm. The intermediate spaces E1, E2 and E3 between the secondary support beams 1B, 1C, 1D and 1E are thus dimensioned so as to effectively limit the risks of an operator passing through the modular support frame OMS.

La présente invention n'est pas limitée aux modes de réalisation qui ont été explicitement décrits, mais elle en inclut les diverses variantes et généralisations contenues dans le domaine des revendications ci-après.The present invention is not limited to the embodiments which have been explicitly described, but it includes the various variants and generalizations contained in the field of the claims below.
