Description
1 L'invention concerne un dispositif de protection frontale anti-chuteThe invention relates to a frontal fall protection device
pour un opérateur appelé à se tenir sur une plate-forme située en partie haute d'une banche, par exemple pour surveiller la mise en place d'armatures, sans risque de chuter du côté de la face coffrante de la banche. Un but de l'invention est un dispositif qui soit escamotable à la demande en restant solidaire de la banche, notamment pour le transport et le stockage de la banche. On y parvient selon l'invention avec un dispositif qui comprend deux montants verticaux tenus dans des guides fixés à la face non coffrante de la banche sous la plate-forme de façon à ce que les montants puissent coulisser verticalement dans les guides à partir d'une position basse de transport ou de stockage de la banche dans laquelle les montants sont escamotés sous la plate-forme en arrière de la face non coffrante, jusque dans une position haute de service où les montants présentent au dessus de la plate-forme une partie de montant moyenne et une partie de montant supérieure, avec des lisses horizontales portées par les montants pour constituer un garde-corps devant l'opérateur entre la plate-forme et la banche, et des moyens étant prévus pour maintenir le garde-corps en position de service, la partie de montant supérieure et la partie de montant moyenne ayant sensiblement même hauteur et étant articulées à pivotement l'une sur l'autre autour d'un axe parallèle aux lisses pour que les parties supérieures puissent se rabattre du côté de la plate-forme sur les parties moyennes en portant les lisses. for an operator called to stand on a platform located in the upper part of a banche, for example to monitor the establishment of frames, without risk of falling on the side of formwork formwork. An object of the invention is a device that is retractable on demand by remaining integral with the form, especially for the transport and storage of the form. It is achieved according to the invention with a device which comprises two vertical uprights held in guides fixed to the non-formwork side of the board under the platform so that the uprights can slide vertically in the guides from a low transport position or stowage storage in which the amounts are retracted under the platform behind the non-formwork face, to a high service position where the amounts have above the platform a part of average amount and a portion of upper amount, with horizontal rails carried by the amounts to form a railing in front of the operator between the platform and the box, and means being provided to maintain the guardrail in position of service, the upper amount portion and the average amount portion having substantially the same height and being hinged to pivot about each other about a parallel axis with the rails so that the upper parts can be folded on the side of the platform on the middle parts while carrying the smooth ones.
2909698 2 Les lisses comportent une lisse supérieure fixée aux extrémités supérieures des parties de montant supérieures, et une lisse inférieure mobile montée à coulisse verticale sur les parties de montant 5 supérieures à partir d'une position basse ou la lisse mobile empêche le pivotement des parties de montant supérieures, la lisse mobile pouvant être sollicitée manuellement vers le haut pour permettre ledit pivotement ou pour permettre l'escamotage des montants.The heddles comprise an upper heald fixed to the upper ends of the upper upright portions, and a lower hoop mounted vertically slidably on the uppermost leg portions from a lower position or the hinged hob prevents pivoting of the hob portions. upper amount, the movable boom can be manually biased upwards to allow said pivoting or to allow the retraction of the amounts.
10 On décrira ci-après un exemple de réalisation d'un dispositif conforme à l'invention en référence aux figures du dessin joint sur lequel : • les figures 1 à 3 sont des vues schématiques d'un montant du dispositif, respectivement en position 15 d'escamotage pour le transport, en position de service et à l'état rabattu ; • la figure 4 est une vue en perspective du dispositif en position de service prise du côté de la face coffrante de la banche, et 20 • la figure 5 est une vue du dispositif à l'état rabattu depuis la plate-forme. Le dispositif comporte deux montants parallèles identiques (2a, 2'a) qui peuvent coulisser verticalement dans des guides (3) fixés à la face non coffrante (la) 25 d'une banche (1), et deux lisses horizontales (5, 6). Sur les figures 1 à 3, on a représenté l'un des montants qui présente une partie de montant supérieure (2a), une partie de montant moyenne (2b) et une partie de montant inférieure (2c). L'autre montant est 30 identique. La partie de montant inférieure (2c) restera sous la plate-forme (7) tandis que les deux autres parties 2909698 3 seront en dessous ou au dessus de la partie selon que le dispositif sera escamoté (figure 1) ou en service (figures 2 et 3)). Une traction vers le haut sur la lisse fixe permet de faire passer le garde-corps d'une 5 position d'escamotage (figure 1) à sa position de service (figure 2). Pour maintenir le dispositif en service, des broches (4) ou tout moyen équivalent bloquent les montants dans les guides. La partie de montant supérieure (2a) coopère avec 10 la partie correspondante (2'a) de l'autre montant pour porter une lisse horizontale fixe (5) située sensiblement aux sommets des montants et pour porter une lisse mobile (6) qui est fixée à des fourreaux (10) qui peuvent coulisser le long des parties de montant 15 supérieures. La partie de montant supérieure (2a) peut pivoter sur l'extrémité de la partie moyenne (2b) autour d'un axe (8) parallèle aux lisses. Lorsque les parties de montant supérieures et 20 moyennes sont au dessus de la plate-forme (7), • soit ces deux parties sont maintenues dans le prolongement l'une de l'autre parce que les fourreaux de la lisse mobile sont en position basse sur les parties supérieures (figure 2) et empêchent 25 le pivotement des parties supérieures, • soit par une traction vers le haut exercée sur la lisse mobile, la lisse et ses fourreaux ont été soulevés et permettent ce pivotement au terme duquel la lisse mobile est descendue et s'est 30 rapprochée de la lisse fixe (figure 3). Dans le premier cas, le garde-corps est en position de service, avant l'installation du coffrage.An exemplary embodiment of a device according to the invention will be described below with reference to the figures of the accompanying drawings in which: FIGS. 1 to 3 are diagrammatic views of an amount of the device, respectively in position 15; retractable for transport, in the service position and in the folded state; FIG. 4 is a perspective view of the device in the service position taken on the side of the formwork face of the formwork, and FIG. 5 is a view of the device in the folded state from the platform. The device comprises two identical parallel uprights (2a, 2'a) which can slide vertically in guides (3) fixed to the non-formworked face (la) of a formwork (1), and two horizontal rails (5, 6 ). In Figures 1 to 3, there is shown one of the amounts having a portion of upper amount (2a), a portion of average amount (2b) and a portion of lower amount (2c). The other amount is 30 identical. The lower leg portion (2c) will remain under the platform (7) while the other two portions 2909698 3 will be below or above the portion depending on whether the device will be retracted (Figure 1) or in service (Figures 2). and 3)). Pulling upwards on the stationary rail makes it possible to move the railing from a retracted position (FIG. 1) to its operating position (FIG. 2). To keep the device in use, pins (4) or equivalent equivalent block the amounts in the guides. The upper upright portion (2a) cooperates with the corresponding portion (2'a) of the other upright to carry a stationary horizontal bar (5) substantially at the tops of the uprights and to carry a movable bar (6) which is attached to sleeves (10) which are slidable along the upper leg portions. The upper amount portion (2a) can pivot on the end of the middle portion (2b) about an axis (8) parallel to the rails. When the upper and middle upright portions are above the platform (7), either these two parts are held in the extension of one another because the sleeves of the movable boom are in the lower position. on the upper parts (FIG. 2) and prevent the upper parts from pivoting, or by an upward traction exerted on the movable rail, the rail and its sleeves have been raised and allow this pivoting, at the end of which the mobile rail is descended and approached the stationary rail (Figure 3). In the first case, the railing is in the service position, before the installation of the formwork.
4 2909698 Dans le deuxième cas, il a pour fonction, après coffrage, de permettre le passage de la benne à béton pour le remplissage de la banche tout en empêchant de débloquer les écrous des tubes de serrage des banches. A 5 cette fin, la lisse supérieure est dotée d'excroissances (11) qui empêchent ce déblocage. De fait, la lisse mobile a deux positions stables vers lesquelles elle est conduite par l'effet de la gravité : 10 • l'une dans laquelle elle se trouve en bas des parties supérieures des montants, maintenant ces montants dressés dans le prolongement des parties inférieures des montants, • l'autre dans laquelle elle se trouve en haut des 15 parties supérieures des montants, soit parce que ces parties sont escamotées sous la plate-forme (à l'exception des lisses), soit parce que les parties supérieures des montants ont été basculées vers le bas sur les parties inférieures.4 2909698 In the second case, it has the function, after formwork, to allow the passage of the concrete bucket for filling the box while preventing unblocking the nuts of the clamping tubes of the panels. To this end, the top rail is provided with protrusions (11) which prevent this release. In fact, the movable rail has two stable positions towards which it is driven by the effect of gravity: • one in which it is at the bottom of the upper parts of the uprights, keeping these uprights erected in line with the parts • the other in which it is at the top of the upper 15 of the uprights, either because these parts are retracted under the platform (with the exception of the rails), or because the upper parts of the uprights uprights were tilted down on the lower parts.
20 Les montants sont par exemple tubulaires à section carrée ou rectangulaire et les lisses sont par exemple des tubes à section circulaire. La hauteur de chacune des parties supérieure et moyenne d'un montant est d'environ 50cm pour que le 25 garde-corps ait une hauteur d'environ 1 mètre. A titre indicatif, le garde-corps à une hauteur totale d'environ 1 mètre. Selon une autre caractéristique de l'invention, la plate-forme 7 est située à distance de l'extrémité 30 supérieure de la banche pour qu'en position d'escamotage des montants les lisses soient sensiblement dans l'intervalle entre cette extrémité et la plate-forme. L'invention n'est pas limitée aux réalisations qui ont été décrites.The uprights are, for example, tubular with a square or rectangular cross-section and the rails are, for example, tubes with a circular section. The height of each of the upper and middle parts of an upright is about 50cm so that the guardrail has a height of about 1 meter. As an indication, the guardrail at a total height of about 1 meter. According to another characteristic of the invention, the platform 7 is located at a distance from the upper end of the formwork so that in the retracted position of the struts the stringers are substantially in the interval between this end and the platform. The invention is not limited to the embodiments that have been described.
