Description
La présente invention est relative à un dispositif de maintien et de blocage utilisé pour positionner et fixer en une seule opération des protections horizontales de garde-corps temporaires de chantiers sur des protections grimpantes lors de l’élévation de bâtiments et plus généralement d’ouvrages.The present invention relates to a holding and blocking device used to position and fix in a single operation horizontal protections of temporary guardrails for construction sites on climbing protections during the elevation of buildings and more generally works.
L’état des technologies relatives aux dispositifs de maintien des éléments horizontaux de sécurité peuvent se distinguer selon deux familles technologiques :
- La première relative au principe de fixation par blocage volontaire qui permet de maintenir la lisse sur le poteau ou le montant avec une action d’une deuxième main ou bien encore dans un deuxième temps.
- La deuxième relative à un positionnement sans blocage de la lisse lors de sa mise en position The state of technologies relating to devices for holding horizontal safety elements can be distinguished according to two technological families:
- The first relating to the principle of fixing by voluntary blocking which makes it possible to maintain the beam on the post or the amount with the action of a second hand or even in a second time.
- The second relates to a positioning without blocking the beam when it is put in position
La première famille est utilisée pour les protection périphérique et aussi des protections grimpantes pour laquelle nous pouvons citer les brevets FR 3047030 et FR2979931 qui permettent le positionnement et le blocage d’une lisse tubulaire mais qui présentent deux inconvénients : le premier inconvénient de ne pas permettre l’utilisation planches de sécurité ce qui ne confère pas un caractère universel à ce système de fixation; le deuxième inconvénient est de nécessiter une action supplémentaire pour le blocage ou de déblocage de la protection horizontale.The first family is used for peripheral protection and also climbing protections for which we can cite the patents FR 3047030 and FR2979931 which allow the positioning and blocking of a tubular rail but which have two disadvantages: the first disadvantage of not allowing the use of safety boards which does not confer a universal character on this fixing system; the second disadvantage is to require an additional action for the blocking or unblocking of the horizontal protection.
La deuxième famille mentionne un principe de positionnement de la lisse et de maintien de celle-ci pour laquelle nous pouvons citer le brevet FR2895003 «Potelet garde-corps de sécurité » qui présente l’avantage de maintenir la lisse après sa mise en position mais qui présente deux autres inconvénients :
- le premier est que le dispositif ne bloque pas totalement la protection horizontale, la fixation ne disposant pas de fermeture sur le haut de la protection, la protection horizontale peut à tout moment et par un geste involontaire sortir de son logement, ce qui annihile l’objet même de sa présence (sécurité des personnes),
le deuxième est que ce dispositif est vétuste, se basant sur un ressort placé dans la cuvette recevant la protection horizontale, qui ressort pouvant très facilement être déformé par chocs résultants des manipulations successives sur le chantier.The second family mentions a principle of positioning the rail and maintaining it for which we can cite the patent FR2895003 "Safety railing post" which has the advantage of maintaining the rail after it has been put in position but which has two other drawbacks:
- the first is that the device does not completely block the horizontal protection, the binding not having a closure on the top of the protection, the horizontal protection can at any time and by an involuntary gesture come out of its housing, which annihilates the the very purpose of his presence (safety of persons),
the second is that this device is outdated, based on a spring placed in the bowl receiving the horizontal protection, which spring can very easily be deformed by shocks resulting from successive manipulations on the site.
En l’état des techniques, aucun dispositif connu ne permet d’assurer une fixation universelle de tout élément de protection horizontale, qui de plus est se place et se fixe en une seule action. Plus précisément, les dispositifs existants sont contraints en ce que :
- les principes existants pour maintenir les lisses en acier ou les planches demandent de réaliser deux opérations distinctes pendant laquelle la sécurité n'est pas garantie.
- l'accès est limité en ce que l'opérateur est à l'intérieur alors que la protection est à l'extérieure
- ils ne permettent pas l'utilisation de tous les types de lisses (tube et planche) or les gardes corps qui sont généralement utilisés sont soit des tubes, soit des planches de sécurité, soit encore les deux en même temps.In the state of the art, no known device makes it possible to ensure universal fixing of any horizontal protection element, which moreover is placed and fixed in a single action. More specifically, the existing devices are constrained in that:
- the existing principles for maintaining steel stringers or planks require two distinct operations to be carried out during which safety is not guaranteed.
- access is limited in that the operator is inside while the guard is outside
- they do not allow the use of all types of heddles (tube and board) or the guardrails which are generally used are either tubes or safety boards, or even both at the same time.
Enfin les dispositifs de gardes corps comprenant à la fois les poteaux, leur fixation et les lisses dépendent des matériaux avec lesquels ils sont constitués et aussi des conditions d’utilisations relativement à la norme NF EN13374.Finally, the guardrail devices including both the posts, their fixing and the rails depend on the materials with which they are made and also on the conditions of use relative to standard NF EN13374.
Présentation de l’invention: L’invention est relative à un dispositif de maintien et de blocage en une seule opération de protections horizontales de garde-corps temporaires de chantiers pour toutes protections grimpantes , caractérisé par :
- deux montants verticaux (a) placés de part et d’autre du mât et le constituant par liaison de séries de deux plats (b),
- ces séries de deux plats (b) sont soudées sur les montants verticaux (a) et forment une échelle (c) sur le montant,
- au moins un clinquant (ressort) (d) en acier se positionne verticalement entre les deux montants verticaux (a), la longueur du clinquant est supérieure à la hauteur des montants (a) aux fins de lui permettre un champs de latitude transversal lui donnant une forme de vague,
- un bloqueur(e) composé d’un plat recourbé (f) avec au moins 3 ouvertures (g) en son centre qui correspondent aux passage des tubes et du (ou des) clinquant, ce bloqueur (e) est traversé par les montants (a) et le clinquant (d) aux fins de se déplacer pour bloquer verticalement la protection horizontale (h),
- la distance (i) entre le cliquant (d) et l'un des montant (a) est telle qu'elle peut accepter toute dimension de protection horizontale (h), en forçant sa mise en place par le déplacement transversal du clinquant (d) qui maintien par coincement la dite protection horizontale (h),
- dans le même mouvement le bloqueur (e) se positionne sur la protection horizontale (h) par gravité. Presentation of the invention : The invention relates to a device for holding and blocking in a single operation horizontal protections for temporary guardrails on construction sites for all climbing protections, characterized by:
- two vertical uprights (a) placed on either side of the mast and making it up by linking a series of two plates (b),
- these series of two plates (b) are welded to the vertical uprights (a) and form a ladder (c) on the upright,
- at least one shim (spring) (d) in steel is positioned vertically between the two vertical uprights (a), the length of the shim is greater than the height of the uprights (a) in order to allow it a transverse latitude field giving a wave shape,
- a blocker(e) composed of a curved flat (f) with at least 3 openings (g) in its center which correspond to the passage of the tubes and the foil(s), this blocker(e) is crossed by the uprights (a) and the foil (d) for the purpose of moving to vertically block the horizontal protection (h),
- the distance (i) between the click (d) and one of the uprights (a) is such that it can accept any dimension of horizontal protection (h), by forcing its installation by the transverse displacement of the click ( d) which maintains the said horizontal protection (h) by wedging,
- in the same movement the ascender (e) is positioned on the horizontal protection (h) by gravity.
Ainsi la protection horizontale (h) ne peut plus se soulever car un phénomène d'arc-boutement se produit si l'effort vertical est appliqué sur la protection horizontale (h).Thus the horizontal protection (h) can no longer rise because an arching phenomenon occurs if the vertical force is applied to the horizontal protection (h).
Pour enlever la protection horizontale (h), il convient de lever le bloqueur (e), le clinquant(d) reprenant alors du mouvement qui libère la protection horizontale (h).
: Vue en perspective de l’ensemble du dispositif
To remove the horizontal protection (h), it is necessary to lift the blocker (e), the shim (d) then resuming movement which releases the horizontal protection (h).
