Definitions
- the present invention relates to the field of modular support frames for supporting a slab formwork or the like, and more particularly relates to a secondary support beam, intended to be arranged between two primary beams to form a modular support frame to support a formwork of slab or the like.
- FIG. 1 An example of a modular support frame for supporting a slab formwork or the like is illustrated on the figure 1 of the document FR 2 900 176 A1 .
- Such a frame comprises primary beams carried by props. Between the primary beams are arranged secondary support beams.
- To form a slab or the like on the top of the modular framework wooden plywood plates are placed on the upper bearing surfaces of the primary beams and secondary support beams. The concrete slab or the like is then poured onto the plywood plates. 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 comprise adjustment means in length. These means allow to freely adjust the length of the secondary support beam to adapt to a specific gap between two primary beams of a modular support frame to support a slab formwork or the like.
- the wall panel M1 forms an angle A1 greater than 90 ° with the wall panel M2.
- the wall panel M2 forms an angle A2 greater than 90 ° with the wall panel M3.
- the wall panel M3 connects to a panel of M4 wall at an angle A3 greater than 90 °.
- the wall panel M4 forms a 90 ° angle A4 with the wall panel M1.
- the secondary support beams P2A to P2X are arranged perpendicularly to the primary beams P1A to P1D which are parallel to the wall panel M1.
- the primary beam P1 B and the secondary support beam P2F there remains an empty TR2 trapezium between the wall panel M3, the secondary support beam P2L and the primary beams P1 B and P1 C.
- the secondary support beam P2X runs along the wall panel M4 which is perpendicular to the wall. wall 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 trapezium TR2 resting only on the secondary support beams P2A to P2X and the primary beams P1 A to P1 D.
- a problem proposed by the present invention is to allow a simple and fast way of adapting a modular support frame, to support a slab formwork or the like, the walls of a building forming between them angles different from 90 ° to better secure operators and effectively support the slab.
- the present invention aims to provide a secondary support beam for positioning more accurate than the beams of the prior art, to adapt even more precisely a modular support frame for slab formwork or the like to the angles formed between the walls of a building, while effectively limiting the risk of rotation of the secondary support beam when an operator walks on it.
- the invention provides 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 supporting 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 primary beams and secondary support beam.
- the secondary support beam can thus be arranged between the primary beams at an angle, in particular enabling it to pass along a wall that forms an angle different from 90 ° with respect to the primary beams.
- the secondary support beam according to the invention can thus be arranged in the right triangle TR1 or in the trapezium TR2 to support a plywood plate.
- connection structures having different widths are particularly advantageous.
- the width of the second connecting structure can be chosen on the one hand sufficiently small so that the second connecting structure can be arranged in the immediate vicinity of the wall panel along and making an angle different from 90 ° with the primary beams between which is disposed the secondary support beam.
- the second connection structure can also be arranged in the immediate vicinity of the second connecting structure of an adjacent secondary support beam, the two adjacent beams being arranged in a converging beam towards their second end with the first longitudinal directions of the two beams. adjacent not parallel to each other.
- the width of the first connecting structure can be chosen to be sufficiently large so as to effectively limit the risks of rotation of the secondary support beam around the first longitudinal direction when an operator is walking on the modular frame of Support works on the upper bearing surface of the secondary support beam.
- the length adjustment means may comprise a first section and a second section extending respectively along second and third longitudinal directions and arranged to slide relative to one another in the first longitudinal direction by means of slideway to be movable between a retracted position, in which the overlap of one section by the other is the largest, and at least one extension position, in which the overlap of one section by the other is less only in a fallback position.
- the length adjustment means thus have a very simple constitution, robust, and can be easily and quickly implemented to adjust the length of the secondary support beam.
- the width of the first connecting structure greater than the maximum width of the secondary support beam, effectively limits the risk of rotation of the secondary support beam around the first longitudinal direction when an operator walking on the frame Modular support works on the upper bearing surface of the secondary support beam.
- the first connecting structure may extend in width equally on both sides and away from the first pivoting direction.
- the risk of rotation of the secondary support beam around the first longitudinal direction is thus identically limited in both directions of rotation about the first longitudinal direction.
- the first connecting structure when the transverse direction along which the first connecting structure extends in width is perpendicular to the first longitudinal direction, the first connecting structure may extend in width away from the first pivoting direction and beyond the maximum width of the secondary support beam, in at least one direction, with a maximum distance of approximately 10 cm.
- the gap between the adjacent secondary support beams will be maximum in the vicinity of their first connection structures and will be at most about 20 cm. Such a gap limits the risks that an operator can fall into the space between the two adjacent secondary support beams so arranged.
- the second connecting structure can thus be arranged even more in the immediate vicinity of the wall panel along and forming an angle different from 90 ° with the primary beams between which is disposed the secondary support beam.
- the second connecting structure can also be arranged even more in close proximity to the second connecting structure of an adjacent secondary support beam, the two adjacent beams being arranged in a converging beam towards their second ends with the first longitudinal directions not parallel to each other.
- the first and second connection structures are respectively pivotable about the first and second pivotal directions at an angular amplitude of about 80 degrees.
- Such pivoting amplitude allows the secondary support beam to adapt to the majority of angles that can form a wall section with the two primary beams between which is disposed the secondary support beam.
- each connection structure may comprise a lower hooking structure shaped to come into vertical support simply by moving downward on a lateral structure for receiving a primary beam or a stay in a vertical support zone, and to cling to the receiving side structure so as to oppose any axial displacement to and away from the primary beam or strut.
- connection structures allow an easy and quick installation of the secondary support beam on the lateral structure of receiving a primary beam or a strut by a pose performed in a simple movement. After this installation, the inhibition of any axial displacement towards and away from the primary beam or the strut helps to maintain good place secondary support beam, which increases the safety of the operators.

Comme enseigné dans le document
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
Lorsqu'une ossature modulaire de soutien OMS pour soutenir un coffrage de dalle ou analogue est mise en place, comme illustré sur la
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 supporting beam in the right triangle TR1 and in the trapezoid TR2 constitutes a danger for a user wandering on the plywood plates, which can accidentally pass through the WHO modular support frame (through the right triangle TR1 or through trapezium TR2). The lack of support also affects the strength of the formwork to support the slab before concrete setting.

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 allow a simple and fast way of adapting a modular support frame, to support a slab formwork or the like, the walls of a building forming between them angles different from 90 ° 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 for positioning more accurate than the beams of the prior art, to adapt even more precisely a modular support frame for slab formwork or the like to the angles formed between the walls of a building, while effectively limiting the risk 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 and other objects, the invention provides a secondary support beam according to
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 supporting 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 primary beams and secondary support beam. The secondary support beam can thus be arranged between the primary beams at an angle, in particular enabling it to pass along a wall that forms an angle different from 90 ° with respect to the primary beams. The secondary support beam according to the invention can thus be arranged in the right triangle TR1 or in the trapezium 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 connecting structure can be chosen on the one hand sufficiently small so that the second connecting structure can be arranged in the immediate vicinity of the wall panel along and making an angle different from 90 ° with the primary beams between which is disposed the secondary support beam. The second connection structure can also be arranged in the immediate vicinity of the second connecting structure of an adjacent secondary support beam, the two adjacent beams being arranged in a converging beam towards 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 connecting structure can be chosen to be sufficiently large so as to effectively limit the risks of rotation of the secondary support beam around the first longitudinal direction when an operator is walking on the modular frame of Support works on the upper bearing 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 along second and third longitudinal directions and arranged to slide relative to one another in the first longitudinal direction by means of slideway to be movable between a retracted position, in which the overlap of one section by the other is the largest, and at least one extension position, in which the overlap of one section by the other is less only in a fallback 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 constitution, robust, and can be easily and quickly implemented to adjust the length of the secondary support beam.
De préférence, 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 première structure de raccordement s'étend en largeur, selon la direction transversale perpendiculaire à la première direction longitudinale et à la première direction de pivotement, selon une distance supérieure à la largeur maximale de la poutrelle secondaire de soutien.
- the secondary supporting beam has a maximum cross section defined by a height according to the first or second pivoting direction, and defined by a width in a transverse direction perpendicular to the pivoting directions,
- the first connecting structure extends in width, in the transverse direction perpendicular to the first longitudinal direction and the first pivoting direction, at a distance greater than the maximum width 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 connecting structure, greater than the maximum width of the secondary support beam, effectively limits the risk of rotation of the secondary support beam around the first longitudinal direction when an operator walking on the frame Modular support works on the upper bearing surface 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 connecting structure may extend in width equally on both sides and away from the first pivoting direction. The risk of rotation of the secondary support beam around the first longitudinal direction is thus identically limited in both directions of rotation about 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 along which the first connecting structure extends in width is perpendicular to the first longitudinal direction, the first connecting structure may extend in width away from the first pivoting direction and beyond the maximum width of the secondary support beam, in at least one direction, with 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 supporting beams are disposed adjacent their first connecting structure in abutment against each other and the first longitudinal directions of the two secondary support beams converge toward their second connecting structure or are parallel, the gap between the adjacent secondary support beams will be maximum in the vicinity of their first connection structures and will be at most about 20 cm. Such a gap limits the risks that an operator can fall into the space between the two adjacent secondary support beams so 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.
- the secondary supporting beam has a maximum cross section defined by a height according to the first or second pivoting direction, and defined by a width in a transverse direction perpendicular to the pivoting directions,
- the second connecting structure extends in width, in a transverse direction perpendicular to the first longitudinal direction and the second pivoting direction, at 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 connecting structure can thus be arranged even more in the immediate vicinity of the wall panel along and forming an angle different from 90 ° with the primary beams between which is disposed the secondary support beam. The second connecting structure can also be arranged even more in close proximity to the second connecting structure of an adjacent secondary support beam, the two adjacent beams being arranged in a converging beam towards 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 are respectively pivotable about the first and second pivotal directions at an angular amplitude of about 80 degrees. Such pivoting amplitude allows the secondary support beam to adapt to the majority of angles that can form a wall section with the two primary beams between which is disposed the secondary support beam.
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 may comprise a lower hooking structure shaped to come into vertical support simply by moving downward on a lateral structure for receiving a primary beam or a stay in a vertical support zone, and to cling to the receiving side structure so as to oppose any axial displacement to and away from the primary beam or strut.
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 an easy and quick installation of the secondary support beam on the lateral structure of receiving a primary beam or a strut by a pose performed in a simple movement. After this installation, the inhibition of any axial displacement towards and away from the primary beam or the strut helps to maintain good place secondary support beam, which increases the safety of the operators.
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.
- at least one primary support beam provided on its sides with lateral structures for receiving a connection structure of a secondary support beam as described above, and / or at least one stay with a lateral receiving structure, a connection structure of a secondary support beam as described above,
- at least one secondary support beam as described above.
