Abstract

Improvement in tubular telescopic struts for ensuring greater safety. The improvement involves adding to the base of the shank a tubular abutment 15 force-fitted into the tube 8 and welded to the plate 3. The stroke of the slide 7 is limited in this way, to prevent the possibility that the hand will be crushed between the plate 11 and the nut 6, and the fingers between the slide 7 and the plate 3. The abutment also reinforces the base of the shank which better withstands sledgehammer blows. It is also possible to place at the head of the slide a reinforcement 16 which is also capable of receiving sledgehammer blows if the strut is arranged with the slide downwards. This improvement can apply to all conventional tubular telescopic struts used particularly on public works sites, civil engineering sites, building sites, etc. <IMAGE>

Description

La présente invention concerne les étais télescopiques tubulaires,utilisés en particulier sur les chantiers de Travaux Publics, de Génie Civil,de Batiment etc...The present invention relates to tubular telescopic props, used in particular on public works, civil engineering, building sites, etc.

On connait les étais tubulaires télescopiques classiques,comportant un fût constitué d'un tube métallique dont une extrêmité est filetée pour recevoir un écrou,l'autre extrêmité étant soudée sur une platine,et une coulisse constituée d'un tube métallique de plus petit diamètre percé de trous diamètraux pour recevoir une broche,l'extrêmité libre étant également soudée sur une platine.En charge,la broche prend appui sur l'écrou,de sorte qu'on peut régler au millimètre près la longueur de l'étai.We know the conventional telescopic tubular stays, comprising a barrel made of a metal tube, one end of which is threaded to receive a nut, the other end being welded to a plate, and a slide made of a metal tube of smaller diameter. drilled with diametrical holes to receive a spindle, the free end also being welded to a plate. When loaded, the spindle rests on the nut, so that the length of the forestay can be adjusted to the nearest millimeter.

Pour décharger l'étai,il faudrait normalement desserrer l'écrou avant d'enlever la broche,mais,en pratique,pour aller plus vite,on frappe à coups de masse sur la partie inférieure du fût pour faire riper la platine sur le sol et dégager ainsi l'étai.En procèdant ainsi,on déforme le tube du fût,ce qui détériore la base de l'étai.To unload the forestay, it would normally be necessary to loosen the nut before removing the spindle, but, in practice, to go faster, we strike with blows of mass on the lower part of the barrel to make the plate slide on the ground and thus release the forestay. By doing so, the barrel tube is deformed, which deteriorates the base of the forestay.

Dans ce type d'étai,la coulisse ayant sensiblement la même longueur que le fût (conception économique permettant d'obtenir le maximum de longueur de l'étai pour le minimum de matière),la platine de la coulisse peut venir au contact de l'écrou lorsque l'étai est fermé.Si on manipule l'étai sans précautions particulières après avoir enlevé la broche,on peut se faire écraser la main entre la platine de la coulisse et l'écrou, si l'étai se ferme brutalement sous l'effet du simple poids de la coulisse (plus de 10 Kg pour certains étais ).In this type of forestay, the slide having substantially the same length as the bole (economical design allowing to obtain the maximum length of the forestay for the minimum of material), the plate of the slide can come into contact with the nut when the forestay is closed. If the forestay is handled without special precautions after removing the spindle, you can get your hand crushed between the plate of the slide and the nut, if the forestay suddenly closes under the effect of the simple weight of the runner (more than 10 kg for some struts).

Autre risque d'accident:Les platines sont souvent percées d'un trou central dans lequel on peut introduire les doigts,ce qui est bien pratique pour manipuler l'étai.Si la coulisse a la même longueur que le fût,ou si elle est plus longue que le fût (ce qui est souvent le cas,car on réserve ainsi une garde d'une dizaine de centimètres pour éviter qu'on puisse se faire écraser la main entre la platine de la coulisse et l'écrou) sa partie inférieure peut venir écraser les doigts qu'on aurait malencotreusement introduits dans le trou central de la platine du fût.Another risk of accident: The plates are often pierced with a central hole in which one can introduce the fingers, which is very practical for handling the forestay. If the slide has the same length as the barrel, or if it is longer than the barrel (which is often the case, because we reserve a guard of ten centimeters to avoid that we can be crushed by the hand between the plate of the slide and the nut) its lower part can come to crush the fingers which one would have inadvertently introduced into the central hole of the plate of the barrel.

La présente invention permet de remèdier à ces inconvénients:
Un étai fabriqué suivant l'invention comporte,comme les étais classiques:

  • Un fût avec platine (percée ou non d'un trou central) et un écrou.
  • Une coulisse avec platine (percée ou non d'un trou central) et des trous diamètraux pour recevoir la broche.
En plus de ces éléments traditionnels,il comporte une butée tubulaire ou bien une ou plusieurs butées de forme appropriée,fixées à l'intérieur du fût,par exemple par soudure sur la platine ou sur la paroi du tube du fût. Cette butée (ou ces butées) limite la course de la coulisse,ce qui a deux effets favorables:
  • Même si la coulisse est plus longue que le fût,elle ne pourra jamais venir à proximité de la platine du fût,donc le risque d'écrasenent des doigts malencontreusement introduits dans le trou central de la platine du fût est supprimé.
  • En choisissant une coulisse plus longue que le fût d'une dizaine de centimètres,la platine de celle-ci ne pourra jamais venir au contact de l'écrou.Le risque d'écrasement de la main est donc supprimé.
The present invention makes it possible to remedy these drawbacks:
A forestay manufactured according to the invention comprises, like the conventional forestays:
  • A barrel with plate (pierced or not with a central hole) and a nut.
  • A slide with plate (with or without a central hole) and diametric holes to receive the spindle.
In addition to these traditional elements, it includes a tubular stop or one or more stops of suitable shape, fixed inside the barrel, for example by welding on the plate or on the wall of the barrel tube. This stop (or these stops) limits the travel of the slide, which has two favorable effects:
  • Even if the slide is longer than the barrel, it can never come close to the barrel stage, so the risk of crushing fingers inadvertently inserted into the central hole of the barrel stage is eliminated.
  • By choosing a slide longer than the barrel of about ten centimeters, the plate of this one can never come into contact with the nut. The risk of crushing of the hand is therefore eliminated.

En choisissant correctement la forme et les dimensions de la butée tubulaire (ou des butées multiples),on peut obtenir un autre résultat. Ces butées peuvent servir à renforcer le tube du fût dans sa partie inférieure,ce qui permet d'éviter (ou au moins de limiter) ses déformations sous l'effet des coups de masse.By correctly choosing the shape and dimensions of the tubular stop (or multiple stops), another result can be obtained. These stops can be used to reinforce the barrel tube in its lower part, which makes it possible to avoid (or at least limit) its deformations under the effect of mass blows.

La figure 1 représente en coupe longitudinale un étai tubulaire télescopique classique.Figure 1 shows in longitudinal section a conventional telescopic tubular stay.

La figure 2 représente en coupe longitudinale un étai tubulaire télescopique classique dont la sécurité est améliorée.Figure 2 shows in longitudinal section a conventional telescopic tubular stay whose safety is improved.

La figure 3 représente en coupe longitudinale un étai tubulaire télescopique classique renforcé.FIG. 3 represents in longitudinal section a conventional reinforced telescopic tubular stay.

La figure 4 représente en coupe longitudinale un étai tubulaire classique renforcé,dont la sécurité a été améliorée.FIG. 4 shows a longitudinal section of a reinforced conventional tubular stay, the safety of which has been improved.

La figure 5 représente en coupe longitudinale un étai tubulaire télescopique de sécurité suivent l'invention .Figure 5 shows in longitudinal section a telescopic tubular safety stay according to the invention.

La figure 6 représente une variante de réalisation de la base du fût d'un étai suivant l'invention.FIG. 6 represents an alternative embodiment of the base of the barrel of a forestay according to the invention.

L'étai classique représenté sur la figure 1 en position "fermé" comporte :

  • Le fût 1 constitué d'un tube 2 sur lequel est soudée une platine 3 percée d'un trou central 4,l'autre extrêmité 5 du tube 2 étant filetée pour recevoir un écrou 6.
  • La coulisse 7 constituée d'un tube 8 percé de trous diamètraux 9 destinés à recevoir une broche 10,et d'une platine soudée 11 percée d'un trou central 12.
On voit qu'il est facile de se faire écraser la main entre la platine 11 et l'écrou 6.De même on voit que si on introduit les doigts dans le trou 4 on peut se faire pincer par l'extrêmité inférieure du tube 8 s'il retombe brutalement sur la platine 3.The conventional forestay shown in FIG. 1 in the "closed" position comprises:
  • The barrel 1 consisting of a tube 2 on which is welded a plate 3 pierced with a central hole 4, the other end 5 of the tube 2 being threaded to receive a nut 6.
  • The slide 7 consists of a tube 8 pierced with diametrical holes 9 intended to receive a pin 10, and a welded plate 11 pierced with a central hole 12.
We see that it is easy to be crushed by the hand between the plate 11 and the nut 6. Similarly we see that if we introduce the fingers in the hole 4 we can be pinched by the lower end of the tube 8 if it falls suddenly on the plate 3.

L'étai classique représenté sur la figure 2 est déja plus perfectionné car on ne peut pas se faire écraser la nain entre la platine 11 et l'écrou 6.En effet,la coulisse 7 a une longueur supérieure de 10 cm à 15 cm à celle du fût 1,de sorte qu'elle vient en butée sur la platine 3 en laissant une garde de 10 cm à 15 cm entre la platine 11 et l'écrou 6. On ne peut plus se faire écraser la main à cet endroit,mais on peut encore se faire pincer les doigts entre la coulisse 7 et la platine 3.The classic forestay shown in Figure 2 is already more refined because we can not be crushed the dwarf between the plate 11 and the nut 6.In fact, the slide 7 has a length greater than 10 cm to 15 cm to that of the barrel 1, so that it abuts on the plate 3 leaving a guard of 10 cm to 15 cm between the plate 11 and the nut 6. We can no longer be crushed by hand at this point, but you can still get your fingers pinched between the slide 7 and the plate 3.

L'étai classique représenté sur la figure 3 comporte deux renforts 13 et 14 pour éviter que le fût et la coulisse soient détériorés par les coups de masse,lorsqu'on pose ou dépose l'étai sans jouer sur l'écrou.Le renfort 13 ne présente aucun inconvénient pour la sécurité.Par contre,on voit aisément que le renfort 14 dont la longueur est de l'ordre de 10 cm à 15 cm risque de pincer la main s'il peut venir trop près de l'écrou 6. Pour conserver la sécurité obtenue par la disposition de la figure 2,il faut allonger la coulisse d'environ 10 cm à 15 cm,comme représenté sur la figure 4,ce qui,pour une même longueur d'étai,réduit d'autant sa course.The conventional forestay shown in Figure 3 has two reinforcements 13 and 14 to prevent the barrel and the slide being damaged by ground blows, when the forestay is placed or removed without playing on the nut. does not present any disadvantage for safety. On the other hand, it is easily seen that the reinforcement 14 whose length is of the order of 10 cm to 15 cm risk of pinching your hand if it can come too close to the nut 6. To maintain the security obtained by the arrangement of Figure 2, you must lengthen the slide about 10 cm to 15 cm, as shown in the figure 4, which, for the same forestay length, correspondingly reduces its travel.

L'étai conforme à l'invention représenté sur la figure 5 comporte,comme l'étai télescopique classique:

  • Un fût 1 constitué d'un tube 2 avec une platine soudée 3 percée ou non d'un trou central 4,et une extrêmité filetée 5 recevant un écrou 6.
  • Une coulisse 7 constituée d'un tube 8 parcé de trous diamètraux 9 destinés à recevoir une broche 10,et d'une platine soudée 11 percée ou non d'un trou central 12.
En plus de ces éléments classiques,il comporte :
  • Pour le fût,une butée tubulaire 15 d'une hauteur de 10 cm à 15 cm soudée sur la platine à l'intérieur du fût.Cette butée 15 permet de réserver une garde de 10 cm à 15 cm entre la platine 11 de la coulisse et l'écrou 6,de sorte qu'on ne peut pas se faire écraser la main.
The forestay according to the invention shown in FIG. 5 comprises, like the conventional telescopic forestay:
  • A barrel 1 consisting of a tube 2 with a welded plate 3 pierced or not with a central hole 4, and a threaded end 5 receiving a nut 6.
  • A slide 7 consisting of a tube 8 with diametric holes 9 intended to receive a pin 10, and a welded plate 11 pierced or not with a central hole 12.
In addition to these classic elements, it includes:
  • For the barrel, a tubular stop 15 of a height of 10 cm to 15 cm welded to the plate inside the barrel. This stop 15 allows to reserve a guard of 10 cm to 15 cm between the plate 11 of the slide and nut 6, so you can't get your hand crushed.

Cette butée tubulaire 15 peut également jouer le rôle de renfort du tube 2 au voisinage de la platine 3.Pour cela,la butée tubulaire 15 doit avoir un diamètre extérieur très voisin du diamètre intérieur du tube 2, et doit avoir une épaisseur de paroi suffisante paur résister aux coups de masse.

  • Pour la coulisse,un renfort tubulaire 16 d'une hauteur de 10 cm à 15 cm soudé sur la platine 11 à l'intérieur du tube 8.Pour être efficace,ce renfort doit avoir un diamètre extérieur très voisin du diamètre intérieur du tube 8 et doit avoir une épaisseur de paroi suffisante pour résister aux coups de masse.
Les renforts tubulaires 15 et 16 peuvent d'ailleurs avantageusement être emmanchés à force respectivement dans les tubes 2 et 8.En effet,l'effet de frettage ainsi obtenu améliorera la résistance des couples de tubes 2 et 15 et des couples de tubes 8 et 16 .This tubular stop 15 can also play the role of reinforcement of the tube 2 in the vicinity of the plate 3. For this, the tubular stop 15 must have an outside diameter very close to the inside diameter of the tube 2, and must have a sufficient wall thickness could resist mass blows.
  • For the slide, a tubular reinforcement 16 from a height of 10 cm to 15 cm welded to the plate 11 inside the tube 8. To be effective, this reinforcement must have an outside diameter very close to the inside diameter of the tube 8 and must have a sufficient wall thickness to withstand ground blows.
The tubular reinforcements 15 and 16 can moreover advantageously be force-fitted into the tubes 2 and 8 respectively. Indeed, the hooping effect thus obtained will improve the resistance of the pairs of tubes 2 and 15 and of the pairs of tubes 8 and 16.

La figure 7 est une variante de réalisation de l'invention. Pour simplifier,on n'a représenté en coupe longitudinale que le pied du fût.Pour assurer la sécurité et renforcer le tube 2 au voisinage de la platine 3,on peut remplacer la butée tubulaire 15 par un ensemble de rondelles ou de disques métalliques 17 fixés à l'intérieur du tube 2 , par exemple par soudure.Tout comme la butée tubulaire 15,l'ensemble des disques ou rondelles 17 assurent la sécurité et renforcent le pied du fût. Les rondelles sont préférables aux disques,car elles permettent de conserver une ouverture à la base du fût.
Bien évidemment,on peut adopter la même disposition pour renforcer la tête de la coulisse.Figure 7 is an alternative embodiment of the invention. For simplicity, only the bottom of the barrel has been shown in longitudinal section. To ensure safety and reinforce the tube 2 in the vicinity of the plate 3, the tubular stop 15 can be replaced by a set of washers or metal discs 17 fixed inside the tube 2, for example by welding. Like the tubular stop 15, all of the discs or washers 17 provide security and strengthen the base of the barrel. The washers are preferable to the discs, because they allow to keep an opening at the base of the barrel.
Obviously, we can adopt the same arrangement to strengthen the head of the slide.

Les étais télescopiques suivant l'invention peuvent être utilisés avantageusement pour toutes les utilisations des étais classiques car ils apportent plus de sécurité et possèdent une plus grande longévité. Ils peuvent ainsi être utilisés comme supports de coffrages pour les planchers coulés en place,comme supports provisoires pour les planchers coulés sur prédalles,comme supports de coffrages de poutres,comme étaiement provisoire de poutres préfabriquées,comme étais de séchage soutenant les poutres ou les planchers après décoffrage,pendant la période de durcissement du béton et d'une façon générale pour toutes les opérations d'étaiement.The telescopic struts according to the invention can be advantageously used for all uses of conventional struts because they provide more security and have a longer service life. They can thus be used as formwork supports for floors cast in place, as temporary supports for floors cast on slabs, as beam formwork supports, as temporary shoring of prefabricated beams, as drying props supporting beams or floors after formwork removal, during the concrete hardening period and generally for all shoring operations.
