Description
Pointe de fixation de panneaux de tôle ondulée, de fibrociment ou panneaux analogues.
La présente invention concerne une pointe de fixation de panneaux de tôle ondulée, de fibrociment ou panneaux analogues.Attachment point for corrugated iron panels, fiber cement or similar panels.
The present invention relates to a fixing point for corrugated sheet panels, fiber cement or similar panels.
Les panneaux de tôle ondulée, de fibrociment ou des bacs en acier, en tôle galvanisée ou prélaquée, sont fixés selon les règles de l'art et les prescriptions
DTU (documents techniques unifiés du bâtiment).Corrugated sheet, fiber cement or steel, galvanized or prepainted sheet panels are fixed in accordance with industry standards and regulations
DTU (unified technical building documents).
Cette fixation se fait a l'aide de vis avec interposition d'une rondelle au sommet ou au creux de tonde du panneau ondulé. Lorsque la fixation se fait au sommet de l'onde, la rondelle suffit alors que, si la fixation se fait au creux de l'onde, pour des raisons d'étanchéité, il faut interposer une rondelle d'étanchéité en caoutchouc ou une matière synthétique. This fixing is done using screws with the interposition of a washer at the top or the hollow of the corrugated panel. When the fixing is done at the top of the wave, the washer is sufficient whereas, if the fixing is done in the hollow of the wave, for sealing reasons, it is necessary to interpose a sealing washer of rubber or a material synthetic.
L'inconvénient-de ces fix est que leur mise en place est longue puisqu'il faut les visser. The disadvantage of these fix is that their installation is long since it must be screwed.
I1 existe également un autre type de moyen de fixation constitué par une pointe torsadée, qui s'enfonce non par vissage mais au marteau. Cette mise en place est beaucoup plus rapide que le vissage, mais la tenue à l'arrachement est nettement plus réduite. Dans certaines conditions, notamment dans les régions à fort vent, ce mode de fixation n'est pas satisfaisante car la résistance à l'arrachement est trop faible. I1 also exists another type of fixing means constituted by a twisted point, which is inserted not by screwing but with a hammer. This installation is much faster than screwing, but the resistance to tearing is much reduced. Under certain conditions, especially in regions with strong winds, this method of attachment is not satisfactory because the resistance to tearing is too low.
La présente invention a pour but de créer une pointe pour la fixation de panneaux de couverture
ou de bardage tels que des panneaux de tôle ondulée, des
panneaux de fibrociment, des panneaux de tôle galvanisée ou prélaquée permettant une mise en place rapide des pan
neaux tout en offrant une excellente tenue à l'arrachement
et en permettant le démontage.The object of the present invention is to create a point for fixing cover panels.
or cladding such as corrugated iron panels,
fiber cement panels, galvanized or prepainted sheet panels allowing rapid installation of the panes
while offering excellent resistance to tearing
and allowing disassembly.
A cet effet, l'invention concerne une
pointe caractérisée en ce qu'elle comprend
- une tige ayant une extrémité filetée
par un filetage à section en dents de scie ;
- une tête avec un épaulement ;
- une rondelle rivée sur l'épaulement de
la tete.To this end, the invention relates to a
tip characterized in that it comprises
- a rod having a threaded end
by a sawtooth section thread;
- a head with a shoulder;
- a washer riveted on the shoulder of
the head.
Une pointe, selon l'invention, permet
une fixation particulièrement rapide de panneaux de couver
ture ou de bardage, tels que des panneaux de telle, notamment
de tale ondulée, de fibrociment, etc... puisque cette
pointe s'enfonce à l'aide d'un mateau sans nécessiter de
vissage.A tip according to the invention allows
particularly fast fixing of hatch covers
wall or cladding, such as such panels, in particular
corrugated sheet, fiber cement, etc ... since this
tip sinks with a mat without requiring
screwing.
La pointe présente une résistance à
l'arrachement très grande, par rapport aux pointes torsadées connues. La résistance à l'arrachement d'une telle pointe est assimilable à celle d'une vis enfoncée par vissage.The tip has resistance to
very large pullout, compared to known twisted tips. The pull-out resistance of such a point is comparable to that of a screw driven in by screwing.
I1 est également possible d'enlever une
telle pointe par vissage à l'aide d'une pince.It is also possible to remove a
such point by screwing using pliers.
La pointe, selon l'invention, peut recevoir des rondelles de forme et de dimensions différentes. De façon préférentielle, les rondelles ont une frme circulaire ; toutefois, les rondelles de forme elliptique ou polygonale, notamment carrée ou rectangulaire, sont également envisageables, suivant les applications. The tip according to the invention can receive washers of different shape and dimensions. Preferably, the washers have a circular shape; however, washers of elliptical or polygonal shape, in particular square or rectangular, are also conceivable, depending on the applications.
La présente invention sera décrite de façon plus détaillée à l'aide des figures annexées dans lesquelles
- la figure 1 est une vue ne perspective d'une pointe, selon l'invention
- la figure 2 est une vue de détail en demi-coupe de la pointe selon l'invention
- la figure 3 est un schéma de mise en oeuvre de pointes selon l'invention.The present invention will be described in more detail with the aid of the appended figures in which
- Figure 1 is a perspective view of a tip, according to the invention
- Figure 2 is a detail view in half-section of the tip according to the invention
- Figure 3 is a diagram of implementation of tips according to the invention.
Selon les figures 1 et 2, la pointe se compose d'une tige 1 ayant une extrémité 2 filetée et une extrémité 3 comprenant une tête avec un épaulement 9 (figure 2) portant une rondelle 4, rivée sur cette tête. According to Figures 1 and 2, the tip consists of a rod 1 having a threaded end 2 and an end 3 comprising a head with a shoulder 9 (Figure 2) carrying a washer 4, riveted on this head.
De façon plus détaillée, l'extrémité filetée 2 se compose d'un filetage 5 à section en dents de scie (figure 2) le plan incliné 7 du filet 5 étant tourné vers la pointe 6 et le flanc droit 8 tourné vers la te te 3. In more detail, the threaded end 2 consists of a thread 5 with a sawtooth section (FIG. 2) the inclined plane 7 of the thread 5 being turned towards the point 6 and the straight flank 8 facing towards the te 3.
Le flanc droit 8 est sensiblement une surface hélicoTdale engendrée par une génératrice pratiquement perpendiculaire àl'axe X-X de la vis. The right flank 8 is substantially a helicoTdale surface generated by a generator practically perpendicular to the axis X-X of the screw.
De cette manière, l'extrémité 2 s'enfonce facilement mais est retenue bien à l'arrachement. Comme il s'agit d'un filetage de pas assimilable à celui d'une vis à bois classique, une telle pointe peut se dévisser sans avoir à être arrachée. In this way, the end 2 is easily inserted but is retained well when torn off. As it is a thread of pitch comparable to that of a conventional wood screw, such a point can be unscrewed without having to be torn off.
La tête 3 comporte un épaulement 9 sur lequel s'appuie la rondelle 4 qui est elle-même fixée par écrasement de l'extrémité de la tige 1 pour former la rivure 10. The head 3 has a shoulder 9 on which the washer 4 rests, which is itself fixed by crushing the end of the rod 1 to form the rivet 10.
La figure 3 montre deux possibilités d'utilisation de la pointe, selon l'invention. Figure 3 shows two possibilities of using the tip according to the invention.
Cette pointe sert à fixer un panneau 11 à section ondulée (tôle ondulée, panneau de fibrociment etc...) sur des tasseaux ou chevrons 12. Pour cela, on peut fixer le panneau 11 soit au sommet d'une onde du panneau par une pointe 13 de longueur appropriée. Dans ce cas, il n'est pas nécessaire de prévoir un Joint d'étanchéité entre la rondelle de la pointe 13 et le panneau 11. This point is used to fix a panel 11 with corrugated section (corrugated sheet, fiber cement panel, etc.) on battens or rafters 12. For this, the panel 11 can be fixed either at the top of a wave of the panel by a tip 13 of appropriate length. In this case, it is not necessary to provide a seal between the washer of the tip 13 and the panel 11.
Une seconde manière de fixer le panneau 11 consiste à le fixer dans le creux d'une onde à l'aide d'une pointe 14 de longueur plus courte. Dans ce cas, pour tenir compte de la courbure au fond de l'onde et pour assurer l'étanchéité, il est nécessaire de prévoir un joint d'étanchéité 15 en matière synthétique, caoutchouc ou analogue. A second way of fixing the panel 11 consists in fixing it in the hollow of a wave using a point 14 of shorter length. In this case, to take account of the curvature at the bottom of the wave and to ensure sealing, it is necessary to provide a seal 15 made of synthetic material, rubber or the like.
Des essais d'arrachement faits à l'aide de prototypes de pointes, selon l'invention, ont permis de confirmer la très grande tenue à l'arrachement. Pull-out tests carried out using tip prototypes, according to the invention, made it possible to confirm the very high pull-out resistance.
Ainsi, pour une pointe d'une section de tige de l'ordre de 3,8 Mm, enfoncée dans une poutre de sapin, on a mesuré des efforts d'arrachement de l'ordre de 220 à 270 kg alors que, pour des pointes torsadées, connues, la résistance à l'arrachement dans les mêmes conditions est de l'ordre de 80 à 140 kg. Thus, for a tip with a section of rod of the order of 3.8 mm, driven into a fir beam, we measured pullout forces of the order of 220 to 270 kg whereas, for twisted points, known, the pull-out resistance under the same conditions is of the order of 80 to 140 kg.
I1 convient de remarquer que les tiges de mêre longueur peuvent être munies de rondelles de diamètre ou de forme différentes. It should be noted that the same length rods can be provided with washers of different diameter or shape.
De façon usuelle, les rondelles 4 ont une forme circulaire. I1 est toutefois également possible de prévoir -des rondelles de forme elliptique, carrée, polygonale etc... Usually, the washers 4 have a circular shape. However, it is also possible to provide elliptical, square, polygonal, etc. washers.
Une vis, telle que celle décrite cidessus, se fabrique de la manière suivante
Partant d'une tige, on réalise par frappe à froid, l'épaulement de tête 9 puis, par roulage, on réalise le filetage 5. Dans une seconde série d'opérations, on met en place la rondelle (plate) sur la tête et on la fixe par la rivure. Puis, on donne à la rondelle ainsi mise en place, la concavité appropriée. A screw, such as the one described above, is manufactured in the following manner
Starting from a rod, the head shoulder 9 is produced by cold striking, then, by rolling, the thread 5 is produced. In a second series of operations, the washer (flat) is placed on the head and we fix it by the rivet. Then, the washer thus placed is given the appropriate concavity.
