Description

La présente invention concerne un dispositif d'assemblage d'éléments de structure, tels que des poutres de charpente, et plus particulièrement un tel dispositif d'assemblage comportant un étrier ou sabot. La présente invention concerne aussi un procédé d'assemblage correspondant.The present invention relates to a device for assembling structural elements, such as frame beams, and more particularly to such an assembly device comprising a stirrup or shoe. The present invention also relates to a corresponding assembly method.

Les éléments de structure peuvent être de tout type, et l'invention n'est pas limitée à la fixation de poutres de charpente.The structural elements may be of any type, and the invention is not limited to the attachment of structural beams.

Il est connu d'utiliser des étriers pour assembler rapidement et avec une grande sécurité les différents éléments d'une structure, telle qu'une charpente, notamment dans un bâtiment. Ces étriers sont généralement réalisés en métal et de préférence formées d'un bloc qui comporte une surface de base destinée à recevoir un élément de structure, telle qu'une poutre en bois, et deux surfaces de fixation destinées à se fixer à un élément de support ou porteur. Une difficulté avec ce type d'assemblage est qu'il est nécessaire de fixer précisément l'étrier sur le porteur, avant d'assembler la poutre. Il n'est plus alors possible de modifier, même légèrement, la position de l'étrier sur l'élément porteur. Une autre solution consisterait à fixer l'étrier sur la poutre, puis de fixer cet étrier avec sa poutre sur le porteur. Cette solution nécessite soit deux personnes (une pour maintenir la poutre avec l'étrier au bon endroit, et l'autre pour procéder à la fixation sur le porteur), soit l'utilisation d'un dispositif de support de la poutre au bon endroit. Dans les deux cas, l'assemblage en devient compliqué et donc coûteux. Le document US-3 601 428 décrit des étriers ayant des pointes de fixation monoblocs pour remplacer ou compléter les clous de fixation.It is known to use stirrups to assemble quickly and with great security the various elements of a structure, such as a frame, especially in a building. These stirrups are generally made of metal and preferably formed of a block which comprises a base surface intended to receive a structural element, such as a wooden beam, and two attachment surfaces intended to be attached to an element of carrier or carrier. A difficulty with this type of assembly is that it is necessary to precisely fix the stirrup on the carrier, before assembling the beam. It is no longer possible to modify, even slightly, the position of the stirrup on the carrier element. Another solution would be to fix the stirrup on the beam, then fix the stirrup with its beam on the carrier. This solution requires either two people (one to hold the beam with the stirrup in the right place, and the other to fix it on the carrier), ie the use of a support device of the beam in the right place . In both cases, the assembly becomes complicated and therefore expensive. The document US-3,601,428 discloses stirrups having one-piece fastening spikes for replacing or supplementing the fastening nails.

La présente invention a pour but de remédier à ces inconvénients en réalisant un dispositif et un procédé d'assemblage plus simple à utiliser, de faible coût, et permettant d'améliorer l'assemblage des éléments de structure, tels que des poutres de charpente.The present invention aims to overcome these disadvantages by providing a device and a connection method easier to use, low cost, and to improve the assembly of structural elements, such as structural beams.

Avantageusement, ladite surface de base comporte un bord arrière saillant parallèle auxdites surfaces de fixation et adapté, lorsque l'élément de structure à assembler est disposé sur ladite surface de base, à appuyer sur ledit élément porteur pour éviter un basculement de l'étrier avant que celui-ci ne soit fixé à l'élément porteur au moyen des organes de fixation.Advantageously, said base surface comprises a rear edge projecting parallel to said attachment surfaces and adapted, when the structural element to be assembled is disposed on said base surface, to press on said support member to prevent tilting of the front caliper that it is attached to the carrier element by means of fasteners.

Avantageusement, ledit bord arrière saillant de la surface de base est coplanaire avec lesdites surfaces de fixation.Advantageously, said rear edge projecting from the base surface is coplanar with said fixing surfaces.

Avantageusement, ladite surface de base comporte des moyens de rigidification pour rigidifier ladite surface de base.Advantageously, said base surface comprises stiffening means for stiffening said base surface.

Avantageusement, lesdits moyens de rigidification comportent au moins une nervure de renfort s'étendant parallèlement auxdites surfaces de fixation.Advantageously, said stiffening means comprise at least one reinforcing rib extending parallel to said attachment surfaces.

La présente invention a aussi pour objet un dispositif d'assemblage d'éléments de structure, tels que des poutres de charpentes, comportant au moins un élément porteur et au moins un élément de structure à assembler, et comportant au moins un étrier tel que décrit ci-dessus.The present invention also relates to a device for assembling structural elements, such as structural beams, comprising at least one less a carrier element and at least one structural element to be assembled, and comprising at least one stirrup as described above.

  • la figure 1 est une vue schématique en perspective d'un étrier selon un mode de réalisation avantageux de l'invention,
  • la figure 2 est une vue schématique de face de l'étrier représentée sur la figure 1, et
  • la figure 3 est une vue schématique de coté de l'étrier représentée sur la figure 1.
Other features and advantages of the present invention will appear in the course of the following detailed description of an advantageous embodiment of the invention with reference to the accompanying drawings given by way of non-limiting examples, in which:
  • the figure 1 is a schematic perspective view of a stirrup according to an advantageous embodiment of the invention,
  • the figure 2 is a schematic front view of the stirrup shown on the figure 1 , and
  • the figure 3 is a schematic side view of the stirrup shown on the figure 1 .

La présente invention fournit un dispositif d'assemblage d'éléments de structure, tels que des poutres de charpente comportant un étrier 1, de préférence métallique.The present invention provides a device for assembling structural elements, such as structural beams comprising a stirrup 1, preferably metal.

L'invention s'applique avantageusement aux éléments de charpente, tels que des poutres, mais il est entendu que l'invention n'est pas limitée à ce type de structure, mais au contraire s'applique à tous les types de structure comportant des éléments de structure à assembler.The invention is advantageously applied to structural elements, such as beams, but it is understood that the invention is not limited to this type of structure, but on the contrary applies to all types of structure comprising structural elements to be assembled.

L'étrier 1 comporte avantageusement une forme générale en U, avec une surface de base 10, entourée de deux parois latérales parallèles 30 et 30'. L'élément de structure à assembler (non représenté) est ainsi reçu sur cette surface de base 10, entre lesdites deux parois latérales 30 et 30'. Avantageusement, chaque paroi latérale 30 et 30' comporte un pan coupé 35 et 35' facilitant la mise en place de l'élément de structure à assembler.The stirrup 1 advantageously comprises a generally U-shaped, with a base surface 10, surrounded by two parallel side walls 30 and 30 '. The structural element to be assembled (not shown) is thus received on this base surface 10, between said two side walls 30 and 30 '. Advantageously, each side wall 30 and 30 'comprises a cut-off 35 and 35' facilitating the establishment of the structural element to be assembled.

De préférence, la surface de base 10 et les parois latérales 30 et 30' comportent des trous de fixation, pour permettre la fixation de l'étrier 1 à l'élément de structure à assembler, par exemple à l'aide de clous, boulons, ou tout autre organe de fixation approprié.Preferably, the base surface 10 and the side walls 30 and 30 'comprise fixing holes, to allow the fixing of the stirrup 1 to the structural element to be assembled, for example by means of nails, bolts , or any other suitable fastener.

L'étrier 1 comporte également des surfaces de fixation 20 et 20' pour fixer ledit étrier 1 sur un élément porteur (non représenté), qui peut être une autre poutre, un mur, ou plus généralement tout type de porteur approprié. Ces surfaces de fixation 20 et 20' sont de préférence solidaires chacune d'une paroi latérale respective 30 et 30', en étant avantageusement sensiblement perpendiculaires à ces parois latérales. Les deux surfaces de fixation 20 et 20' sont donc coplanaires, pour être disposées contre l'élément porteur afin d'y être fixées.The stirrup 1 also has attachment surfaces 20 and 20 'for fixing said stirrup 1 on a carrier element (not shown), which may be another beam, a wall, or more generally any type of suitable carrier. These attachment surfaces 20 and 20 'are preferably each integral with a respective side wall 30 and 30', advantageously being substantially perpendicular to these side walls. The two attachment surfaces 20 and 20 'are coplanar, to be arranged against the carrier element to be fixed.

Pour assurer cette fixation, lesdites surfaces de fixation 20 et 20' comportent également au moins un, de préférence une pluralité de trous de fixation, respectivement référencés 25 et 25', permettant fixer l'étrier 1 sur l'élément porteur avec des organes de fixation, tels que par exemple des clous, boulons ou tout autre organe de fixation approprié.To ensure this fixation, said attachment surfaces 20 and 20 'also comprise at least one, preferably a plurality of fixing holes, respectively referenced 25 and 25', for fixing the stirrup 1 to the carrier element with the support members. fasteners, such as, for example, nails, bolts or any other suitable fastener.

Selon l'invention, lesdites surfaces de fixation 20 et 20' comportent des moyens de pré-positionnement permettant de pré-positionner l'étrier 1 sur l'élément porteur sans le fixer. Ce pré-positionnement est suffisant pour permettre de placer l'élément de structure à assembler dans l'étrier, puis de fixer définitivement l'étrier 1 à l'élément porteur au moyen des organes de fixation. Parallèlement et/ou avant et/ou après cette fixation de l'étrier à l'élément porteur, l'élément de structure à assembler peut aussi être fixé de manière définitive dans l'étrier.According to the invention, said attachment surfaces 20 and 20 'comprise pre-positioning means for pre-positioning the stirrup 1 on the carrier element without fixing it. This pre-positioning is sufficient to allow placing the structural element to be assembled in the stirrup, then to permanently fix the stirrup 1 to the carrier element by means of the fasteners. Parallel and / or before and / or after this fixing of the stirrup to the carrier element, the structural element to be assembled can also be permanently fixed in the stirrup.

L'invention permet donc à une seule personne de réaliser l'assemblage, sans utilisation d'aide (homme ou appareil de support) coûteuse.The invention thus allows a single person to perform the assembly without the use of expensive help (man or support device).

Les moyens de pré-positionnement sont de préférence réalisés par des encoches 22 et 22' réalisées dans le bord latéral externe 21 et 21' de chaque surface de fixation 20 et 20'.The pre-positioning means are preferably made by notches 22 and 22 'made in the outer lateral edge 21 and 21' of each fastening surface 20 and 20 '.

Ces encoches 22 et 22'sont donc distinctes des trous de fixation 25 et 25'.These notches 22 and 22 'are therefore distinct from the fixing holes 25 and 25'.

De préférence, chaque bord latéral externe 21 et 21' comporte une seule encoche 22 et 22', ces deux encoches étant prévues avantageusement au même niveau dans la direction verticale desdits bords latéraux externes.Preferably, each external lateral edge 21 and 21 'comprises a single notch 22 and 22', these two notches being advantageously provided at the same level in the vertical direction of said external lateral edges.

Avantageusement, chaque encoche 22 et 22' comporte une surface inférieure sensiblement horizontale, un fond arrondi et une surface supérieure inclinée par rapport à la surface inférieure. Ceci permet un pré-positionnement aisé de l'étrier sur l'élément porteur.Advantageously, each notch 22 and 22 'has a substantially horizontal bottom surface, a rounded bottom and an upper surface inclined with respect to the lower surface. This allows easy pre-positioning of the stirrup on the carrier element.

En utilisation, l'ouvrier fixe deux organes de pré-positionnement, tels que des pointes ou des clous, au même niveau sur l'élément porteur. Avantageusement, l'écartement desdits organes de pré-positionnement est prédéterminé le plus précisément possible pour obtenir un pré-positionnement de l'étrier 1 en une position qui sera de préférence sa position définitive. II positionne ensuite une première encoche 22 sur l'un des deux organes de pré-positionnement, puis resserre, de préférence manuellement, les deux parois latérales 30 et 30' de l'étrier 1. Ce resserrement est rendu possible par la forme en U de l'étrier 1. Il place alors la seconde encoche 22' face au second organe de pré-positionnement, puis relâche lesdites parois latérales 30 et 30' qui reprennent élastiquement leur position initiale, parallèle l'une à l'autre, de sorte que la seconde encoche va se positionner sur le second organe de pré-positionnement. Les surfaces supérieures inclinées des encoches 22 et 22' facilitent ce pré-positionnement. Une fois l'étrier 1 pré-positionné sur l'élément porteur, l'ouvrier peut disposer l'élément de structure à assembler dans l'étrier 1, sans que celui-ci ne bouge ou ne se détache de l'élément porteur. Sans le tenir, il peut ensuite le fixer dans l'étrier, et fixer l'étrier sur l'élément porteur. S'il constate que le positionnement de l'étrier n'est pas optimal, il peut très aisément désengager l'étrier des organes de pré-positionnement, et modifier leur position, pour affiner celle de l'étrier sur l'élément porteur. L'invention simplifie donc l'assemblage, et le rend plus modulable en cas de besoin.In use, the worker fixes two pre-positioning members, such as points or nails, at the same level on the carrier element. Advantageously, the spacing of said pre-positioning members is predetermined as accurately as possible to obtain a pre-positioning of stirrup 1 in a position which will preferably be its final position. II then positions a first notch 22 on one of the two pre-positioning members, then tightens, preferably manually, the two side walls 30 and 30 'of the stirrup 1. This tightening is made possible by the U-shape of the stirrup 1. It then places the second notch 22 'opposite the second pre-positioning member, then releases said sidewalls 30 and 30' which elastically take up their initial position, parallel to each other, so that the second notch will be positioned on the second pre-positioning member. The inclined upper surfaces of the notches 22 and 22 'facilitate this pre-positioning. Once the stirrup 1 pre-positioned on the carrier element, the worker can arrange the structural element to be assembled in the stirrup 1, without it moving or detaching from the carrier element. Without holding it, he can then fix it in the stirrup, and fix the stirrup on the carrier element. If it finds that the positioning of the stirrup is not optimal, it can very easily disengage the stirrup of the pre-positioning members, and change their position, to refine that of the stirrup on the carrier element. The invention thus simplifies assembly, and makes it more flexible when needed.

De plus, lorsque ledit élément porteur est en matériau moyennement dur, tel que du bois, ledit bord arrière 15 est adapté à pénétrer, au moins légèrement, dans ledit élément porteur lorsque l'élément de structure à assembler est disposé sur ladite surface de base 10, renforçant encore davantage le pré-positionnement de l'étrier 1 avant sa fixation sur ledit élément porteur.Advantageously, the base surface 10 has a rear edge projecting parallel to said attachment surfaces 20 and 20 ', and preferably coplanar therewith. This protruding rear edge is adapted, when the structural element to be assembled is disposed on said base surface 10, to strongly press on said support member to prevent tilting of the stirrup 1 before it is fixed to the carrier element by means of fasteners. In addition, when said carrier element is of moderately hard material, such as wood, said rear edge 15 is adapted to penetrate, at least slightly, into said carrier element when the structural element to be assembled is disposed on said base surface. 10, further reinforcing the pre-positioning of the stirrup 1 before its attachment to said carrier element.

Avantageusement, ladite surface de base 10 comporte des moyens de rigidification 16 pour rigidifier ladite surface de base, lesdits moyens de rigidification comportant de préférence au moins une nervure de renfort 16 s'étendant parallèlement auxdites surfaces de fixation 20 et 20'. Cette nervure permet non seulement de rigidifier le fond de l'étrier 1, mais aussi de ramener les efforts sur celle-ci.Advantageously, said base surface 10 comprises stiffening means 16 for stiffening said base surface, said means for stiffening preferably comprising at least one reinforcing rib 16 extending parallel to said attachment surfaces 20 and 20 '. This rib allows not only to stiffen the bottom of the stirrup 1, but also to reduce the efforts on it.

Avantageusement, pour éviter tous risques de blessures, tous les angles de l'étrier 1 sont arrondis, comme visible notamment sur la figure 1.Advantageously, to avoid any risk of injury, all the angles of the stirrup 1 are rounded, as visible in particular on the figure 1 .
