Abstract

The present invention relates to a scaffolding floor provided with a removable access trap door having two leaves. Floor characterised in that each trap door 1 consists of a removable frame 2 and has an opening 3 having two leaves 4, 5 which are installed on hinges 6 and open upwards by pivoting about the said hinges 6.

Description

La présente invention concerne le domaine des échafaudages et a pour objet un plancher amovible muni d'une trappe d'accès amovible à deux battants. The present invention relates to the field of scaffolding and relates to a removable floor provided with a removable access hatch with two leaves.

Actuellement, les planchers amovibles d'échafaudages sont munis de trappes à un seul battant, pivotable sur charnière ou coulissant, le cadre de la trappe étant intégré de manière non démontable dans le plancher de l'échafaudage. Currently, removable scaffolding floors are fitted with single-leaf hatches, pivotable on a hinge or sliding, the hatch frame being integrated in a non-removable manner into the scaffolding floor.

Ces trappes présentent donc un double inconvénient. D'une part, elles sont à un seul battant, ce qui les rend difficilement manoeuvrables. En effet, lorsque le battant est monté sur charnière, l'utilisateur parvenant au sommet de l'échelle le soulève à l'aide de sa tête. These hatches therefore have a double drawback. On the one hand, they are single-leaf, which makes them difficult to maneuver. When the leaf is hinged, the user reaching the top of the ladder lifts it with his head.

Le poids élevé d'un battant d'un seul tenant, ainsi que sa surface importante le rendent particulièrement peu maniable à l'ouverture. Ceci est également le cas en ce qui concerne les battants coulissants. Ces battants demeurent donc très souvent en position ouverte, ce qui est dangereux et contraire aux normes de sécurité.The high weight of a single leaf, as well as its large surface area make it particularly difficult to open. This is also the case with regard to the sliding leaves. These leaves therefore very often remain in the open position, which is dangerous and contrary to safety standards.

D'autre part, le cache de ces trappes est solidaire du plancher de l'échafaudage. Seul le battant est démontable, ce qui, lors du montage ou du démontage de l'échafaudage, implique une perte de temps considérable. On the other hand, the cover of these hatches is integral with the floor of the scaffolding. Only the leaf is removable, which, when assembling or disassembling the scaffolding, involves a considerable loss of time.

La présente invention a pour but de pallier ces inconvénients. The present invention aims to overcome these drawbacks.

Elle a, en effet, pour objet, un plancher amovible pour échafaudages muni d'une ou plusieurs trappes d'accès disposées au sommet de chaque échelle d'accès permettant le passage d'un niveau à l'autre de l'échafaudage, caractérisé en ce que chaque trappe est constituée par un cadre amovible et présente une ouverture à deux battants montés sur charnières et s'ouvrant vers le haut par pivotement autour desdites charnières. It has, in fact, for object, a removable floor for scaffolding provided with one or more access hatches arranged at the top of each access ladder allowing the passage from one level to the other of the scaffolding, characterized in that each hatch is constituted by a removable frame and has an opening with two leaves mounted on hinges and opening upwards by pivoting around said hinges.

L'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence aux dessins schématiques annexés, dans lesquels la figure 1 est une vue en perspective d'un plancher amovible muni d'une trappe d'accès conforme à l'invention la figure 2 est une vue éclatée en perspective de la trappe, et la figure 3 est une vue en perspective d'un échafaudage muni de planchers amovibles avec trappes d'accès. The invention will be better understood thanks to the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawings, in which FIG. 1 is a view in perspective of a removable floor provided with an access hatch according to the invention, FIG. 2 is an exploded perspective view of the hatch, and FIG. 3 is a perspective view of a scaffolding provided with removable floors with access hatches.

Conformément à l'invention, la trappe 1 est constituée par un cadre amovible 2 et présente une ouverture 3 à deux battants 4, 5 montés sur charnières 6 et s'ouvrant vers le haut par pivotement autour desdites charnières 6 (figure 1). According to the invention, the hatch 1 is constituted by a removable frame 2 and has an opening 3 with two leaves 4, 5 mounted on hinges 6 and opening upwards by pivoting around said hinges 6 (FIG. 1).

Lorsque les deux battants 4, 5 de la trappe 1 sont rabattus et qu'un utilisateur parvenu au sommet de l'échelle d'accès disposée sur chaque niveau veut passer d'un niveau inférieur à un niveau supérieur de l'échafaudage, il continue de grimper le long de l'échelle, rencontrant ainsi avec sa tête les deux battants 4, 5 de la trappe 1 qu'il pousse de ce fait vers le haut en direction des flèches 7. Ainsi, les battants 4, 5 de la trappe s'ouvrent très facilement en raison de leur faible poids respectif et de leur faible surface. When the two leaves 4, 5 of the hatch 1 are folded down and a user who has reached the top of the access ladder arranged on each level wants to go from a lower level to an upper level of the scaffolding, he continues to climb along the ladder, thus meeting with its head the two leaves 4, 5 of the hatch 1 which it therefore pushes upwards in the direction of the arrows 7. Thus, the leaves 4, 5 of the hatch open very easily due to their respective low weight and small surface.

Bien entendu, au sommet de chaque échelle d'accès est disposée une trappe 1. Une échelle d'accès est, de préférence, prévue pour chaque plancher, soit une trappe d'accès 1 par plancher amovible, ces derniers étant soit grillagés, soit en contre-plaqué, ou autres. Les trappes 1 peuvent être réalisées en bois, en contre-plaqué, en aluminium ou tout autre matériau. Selon la figure 1, le cadre amovible 2 est fixé au plancher amovible 8 à l'aide d'éléments 9 en forme de L, fixés le long des parois longitudinales du plancher 8 par des vis 10, lesdits éléments 9 bloquant ainsi ledit cadre 2 en position horizontale dans le prolongement du plancher 8. Of course, at the top of each access ladder is disposed a hatch 1. An access ladder is preferably provided for each floor, either an access hatch 1 by removable floor, the latter being either screened or plywood, or other. The hatches 1 can be made of wood, plywood, aluminum or any other material. According to FIG. 1, the removable frame 2 is fixed to the removable floor 8 using L-shaped elements 9, fixed along the longitudinal walls of the floor 8 by screws 10, said elements 9 thus blocking said frame 2 in a horizontal position in line with the floor 8.

Lors du montage de l'échafaudage, la trappe 1 peut donc être très rapidement mise en place par insertion dans une ouverture 14, de même dimension et de même forme que la trappe 1, prévue dans le plancher 8. Pour maintenir la trappe 1 en place, il suffit de bloquer son cadre 2 dans le plancher 8. Pour cela, deux éléments9 seulement sont nécessaires, chacun étant fixé à l'aide d'une vis 10 sur une paroi latérale du plancher 8. Ainsi, le montage ou le démontage d'une trappe 1 conforme à l'invention ne nécessite que le serrage ou le desserrage de deux vis 10. During assembly of the scaffolding, the hatch 1 can therefore be very quickly put in place by insertion into an opening 14, of the same dimension and the same shape as the hatch 1, provided in the floor 8. To maintain the hatch 1 in place, just block its frame 2 in the floor 8. For this, only two elements9 are necessary, each being fixed with a screw 10 on a side wall of the floor 8. Thus, mounting or dismounting of a hatch 1 according to the invention requires only the tightening or loosening of two screws 10.

Selon une autre caractéristique de l'invention, le cadre amovible 2 est muni, à hauteur de l'une des charnières 6 disposées le long de chaque paroi latérale du cadre 2, d'au moins un arrêt 11 sous forme d'une languette maintenue en place par collage, soudage ou vissage. According to another characteristic of the invention, the removable frame 2 is provided, at the height of one of the hinges 6 disposed along each side wall of the frame 2, with at least one stop 11 in the form of a maintained tongue in place by gluing, welding or screwing.

Cet arrêt 11 évite que les battants 4, 5 ne retombent brutalement, soit sur les côtés longitudinaux du plancher 8, détériorant ainsi les charnières 6, soit contre les façades contre lesquelles sont placés les échafaudages.This stop 11 prevents the leaves 4, 5 from falling suddenly, either on the longitudinal sides of the floor 8, thus damaging the hinges 6, or against the facades against which the scaffolding is placed.

Selon une autre caractéristique de l'invention, les deux battants 4, 5 présentent chacun une surface équivalente à celle de la moitié de l'ouverture 3, et comportent chacun un évidement-12 le long de leur arête intérieure 13 et situé à égale distance de l'un des côtés latéraux du cadre 2, de telle manière que, lorsque les arêtes intérieures 13 sont en contact et que la trappe est fermée, les deux évidements 12 forment un trou dans lequel l'utilisateur situé sur le plancher 8 peut introduire l'ùn de ses doigts. According to another characteristic of the invention, the two leaves 4, 5 each have an area equivalent to that of half of the opening 3, and each have a recess-12 along their inner edge 13 and located at equal distance from one of the lateral sides of the frame 2, so that, when the internal edges 13 are in contact and the hatch is closed, the two recesses 12 form a hole in which the user located on the floor 8 can introduce one of his fingers.

Chaque évidement 12 sera, de préférence, semicirculaire, deux évidements 12 formant ainsi un trou circulaire. Each recess 12 will preferably be semi-circular, two recesses 12 thus forming a circular hole.

La trappe 1 pourra alors être facilement ouverte par un utilisateur se trouvant sur le plancher 8 et désirant descendre au niveau inférieur. En introduisant l'un de ses doigts dans le trou circulaire formé par les deux évidements circulaires 12, il lui sera aisé d'ouvrir la trappe 1 du fait du faible poids de chacun des battants 4, 5. The hatch 1 can then be easily opened by a user on the floor 8 and wishing to descend to the lower level. By inserting one of his fingers into the circular hole formed by the two circular recesses 12, it will be easy for him to open the hatch 1 because of the light weight of each of the leaves 4, 5.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments, ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.  Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements, or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
