Abstract

The invention relates to a device preventing the unauthorised removal of the elements for closing technical trunking used by the public services for distribution of cable networks; this device which can be fitted to all access points of the type closed off by multiple slabs includes a system for recovering foreign bodies capable of slipping through the openings via which the slabs are handled and of presenting a risk of injury for those making the intervention. The device consists in fitting to each of the existing closure slabs (1), male metal fingers (2) and female inserts (3) allowing immobilisation by degrees, and in the installation of the civil engineering works of a raisable metal plate (4) allowing the whole unit to be locked. The recovery system is made up of a raisable articulated chute (channel, gutter) (5) located on the underside of the slabs.

Description

La présente invention concerne un système de sécurisation adaptable aux trappes de visite, à fermeture par dalles juxtaposées, que l'on rencontre au sol et qui assurent la desserte des caniveaux techniques qu'exploitent les services publics pour la distribution des réseaux câblés, téléphoniques, électriques ou de fibres optiques. The present invention relates to a security system adaptable to inspection hatches, closed by juxtaposed slabs, which are encountered on the ground and which provide service to the technical channels used by the public services for the distribution of cable, telephone, electrical or optical fibers.

Ces trappes sont actuellement obturées par de simples dalles amovibles réalisées en béton armé, généralement non verrouillables, laissant ainsi toute liberté d'action à des actes de vandalisme ou de sabotage sur les installations qu'elles sont sensées protéger. These hatches are currently closed by simple removable slabs made of reinforced concrete, generally not lockable, thus leaving all freedom of action to acts of vandalism or sabotage on the installations that they are supposed to protect.

Le système présenté permet, par des adaptations simples, réalisables sur site, l'installation sans reprise du gros oeuvre existant, d'une sécurisation a posteriori des accès par adjonction d'ensembles mécaniques préfabriqués de protection et de verrouillage. The system presented allows, by simple adaptations, achievable on site, the installation without resumption of the existing structural work, of an a posteriori securing of the accesses by addition of prefabricated mechanical assemblies of protection and locking.

Le système de sécurisation consiste dans l'adaptation dans le dormant existant et sur le flanc des dalles de fermeture (la) (lb) à l'exception de la dalle d'extrémité (lc) d'un clavetage de proche en proche réalisé par des doigts métalliques mâles (2) et des inserts femelles (3) et par l'adjonction en sous face de la dalle d'extrémité (lc) d'une plaque métallique de blocage (4), relevable par une poignée de manoeuvre, verrouillable, articulée sur une platine (8) fixée au dormant d'ouverture. Cette plaque assure l'occultation de l'espace libre correspondant à l'emplacement de la dalle d'extrémité et le blocage en position de Ia dalle clé (lb) en venant prendre appui sur un patin antisoulèvement (6) soudé en sous-face de celle-ci. The security system consists in adapting the existing frame and on the side of the closing slabs (la) (lb) with the exception of the end slab (lc) of a keying step by step made by male metal fingers (2) and female inserts (3) and by the addition on the underside of the end plate (lc) of a metal blocking plate (4), liftable by an operating handle, lockable , articulated on a plate (8) fixed to the opening frame. This plate ensures the concealment of the free space corresponding to the location of the end slab and the locking in position of the key slab (lb) by coming to bear on an anti-lifting pad (6) welded on the underside of it.

Le système comporte en outre une goulotte en U (5) de récupération des corps étrangers susceptibles de pénétrer dans la trémie. The system further includes a U-shaped chute (5) for recovering foreign bodies likely to enter the hopper.

Les schémas annexés illustrent l'invention. The attached diagrams illustrate the invention.

La figure t représente la coupe en long d'une trémie à occultation par trois dalles : le dormant (0) et les dalles existantes (1) sont représentées en coupe hachurée, les adaptations et installations complémentaires correspondant au dispositif de sécurisation sont représentées en traits continus. Figure t represents the cross section along a hopper occulted by three slabs: the frame (0) and the existing slabs (1) are shown in hatched cross-section, the adaptations and additional installations corresponding to the safety device are shown in lines continuous.

La figure 2 représente la même trémie en vue de dessus avec ses trois dalles représentées en tirets courts et la trémie d'ouverture représentée en tirets longs alors que les adaptations et installations complémentaires correspondant au dispositif de sécurisation sont représentés en traits continus.FIG. 2 represents the same hopper in top view with its three slabs represented in short dashes and the opening hopper represented in long dashes while the adaptations and complementary installations corresponding to the securing device are shown in solid lines.

La figure 3 représente la même coupe en long, dalles enlevées, les inserts de verrouillage (3) de première dalle scellés dans le dormant avant (0), et la plaque métallique de verrouillage (4) accrochée en place sur le dormant arrière est montée en position ouverte livrant l'accès aux intervenants.Figure 3 shows the same cross-section, tiles removed, the locking inserts (3) of the first tile sealed in the front frame (0), and the metal locking plate (4) hung in place on the rear frame is mounted in the open position providing access to responders.

En référence aux figures 1 et 2 et selon la nécessité de modifier les dalles de béton qui se succèdent pour assurer le verrouillage de proche en proche, la modification consiste dans le rapport sur la tranche avant des dalles de doigts métalliques (2) qui viennent se loger dans des inserts femelles (3) scellés dans le dormant avant (0) de l'ouverture ou sur la tranche arrière des dalles. En sous face de la tranche arrière de l'avant dernière dalle ou dalle clé, on vient rapporter par soudure un patin antisoulèvement (6) qui sert d'appui à la plaque métallique articulée lorsqu'elle est rabattue et verrouillée. With reference to FIGS. 1 and 2 and according to the need to modify the concrete slabs which follow one another to ensure the locking step by step, the modification consists in the report on the front edge of the metal finger slabs (2) which come place in female inserts (3) sealed in the front frame (0) of the opening or on the rear edge of the tiles. On the underside of the rear edge of the penultimate slab or key slab, there is brought by welding an anti-lifting pad (6) which serves as a support for the articulated metal plate when it is folded down and locked.

En référence aux figures 1 et 2 et selon la nécessité de blocage de l'ensemble des dalles de verrouillage (la) (lb) par une plaque métallique (4), celle-ci est réalisée à partir d'une tôle acier pliée mécanosoudée galvanisée à chaud, le pliage forme un caisson rentrant qui permet la manoeuvre du bloc de verrouillage et le dégagement pour la prise de la poignée de relevage (17). La plaque métallique étant protégée de la circulation par une dalle de béton (lc) sa réalisation est de construction suffisamment légère pour être facilement relevable.Une serrure à commande par clé à quatre pans (12) et à accès protégé par un canon amovible (11) en est solidaire, cette serrure est montée horizontalement (afin d'être protégée de toute entrée d'eau) boulonnée en applique extérieure sur le flanc du caisson de la plaque, et accessible l'intérieur du caisson rentrant après enlèvement de la plaque en béton (lc). With reference to FIGS. 1 and 2 and according to the need to block all of the locking slabs (la) (lb) by a metal plate (4), this is made from a folded galvanized mechanically welded sheet steel when hot, the folding forms a re-entrant box which allows the operation of the locking block and the clearance for taking the lifting handle (17). The metal plate being protected from circulation by a concrete slab (lc), its construction is of sufficiently light construction to be easily lifted. A lock controlled by a Allen key (12) and access protected by a removable barrel (11 ) is integral with it, this lock is mounted horizontally (in order to be protected from any ingress of water) bolted on the outside wall on the side of the plate casing, and accessible inside the returning casing after removal of the plate in concrete (lc).

En référence aux figures 1 et 2 et selon la nécessité de récupérer les corps étrangers susceptibles d'être introduits par les opercules de manoeuvre des dalles un dispositif récupérateur est monté longitudinalement en sous face des dalles de verrouillage. I1 s'agit d'une goulotte (5) en U composée de deux tronçons articulés, relevables, autour d'un axe horizontal monté dans un sabot (14) scellée dans le génie civil. Chacun des deux tronçons est solidaire d'une barre de contact (15) transversale aux fins d'assurer les appuis intermédiaires sur des cornières (16) scellées latéralement dans l'ouverture. With reference to FIGS. 1 and 2 and according to the need to recover the foreign bodies liable to be introduced by the covers for operating the slabs, a recovery device is mounted longitudinally below the locking slabs. I1 is a U-shaped chute (5) composed of two articulated sections, liftable, around a horizontal axis mounted in a shoe (14) sealed in civil engineering. Each of the two sections is integral with a transverse contact bar (15) in order to provide intermediate supports on angles (16) laterally sealed in the opening.

En référence à ces dessins et selon la nécessité de réaliser le scellement des doigts (2) et des inserts (3) la première intervention consiste dans le perçage à l'aide d'un gabarit, du dormant avant (0) et des tranches avant et arrière des dalles à verrouiller (la) (lb).  With reference to these drawings and according to the need for sealing the fingers (2) and the inserts (3), the first intervention consists in drilling with a template, the front frame (0) and the front edges. and rear of the slabs to be locked (la) (lb).

En référence à la figure 1 et selon la nécessité d'adaptations différentes sur les dalles selon leurs positions respectives dans la trémie on distingue trois types de dalles: - dalle arrière (Ic) : sur laquelle aucune adaptation n'est réalisée cette dalle n'assurant qu'un rôle de protection de la plaque métallique de verrouillage, - avant dernière dalle (lb) ou dalle clé : l'adaptation consiste dans le perçage de la tranche avant et le scellement de deux doigts de verrouillage (2) et dans la soudure en sous face du flanc arrière de trois pattes de liaison (7) supports du patin d'appui (6) de la plaque métallique articulée (4). With reference to FIG. 1 and according to the need for different adaptations on the slabs according to their respective positions in the hopper, there are three types of slabs: - rear slab (Ic): on which no adaptation is made this slab does not ensuring that a protective role of the metal locking plate, - penultimate slab (lb) or key slab: the adaptation consists in drilling the front edge and sealing two locking fingers (2) and in the welding on the underside of the rear flank of three connecting lugs (7) supports of the support shoe (6) of the articulated metal plate (4).

- dalle avant (la) ou dalles avants dans le cas d'une trémie à quatre dalles et plus l'adaptation consiste dans le perçage des flancs avant et arrière et dans le scellement sur le flanc avant de deux doigts de verrouillage (2) et sur le flanc arrière de deux inserts femelles (3).- front slab (la) or front slabs in the case of a hopper with four slabs and more the adaptation consists in drilling the front and rear flanks and in the sealing on the front flank of two locking fingers (2) and on the rear flank of two female inserts (3).

En référence aux figures 1 et 3 et selon la nécessité d'une installation rapide et exempte de règlage de l'ensemble articulé de verrouillage, on procède de la façon suivante: - une contreplaque (10), rigidifiée par deux goussets d'angle (18), percée de deux trous filetés servant au logement des vis de règlage (13), est positionnée sur le dormant arrière de la trémie et fixée au génie civil, soit par soudure sur le cadre métallique d'origine soit par scellement dans le parement de l'ouverture, - puis les dalles de verrouillage (la) et (lb) sont mises en place et l'ensemble, plaque métallique (4) et sa platine charnière (8) qui porte également le bloc verrou du pène de serrure (9), est présenté dans l'espace restant à obturer : la platine (8), qui porte deux lumières de passage des vis de règlage et d'appui (13) sur la contreplaque, est règlée, bloquée puis définitivement solidarisée par soudure avec la contreplaque (10). With reference to FIGS. 1 and 3 and according to the need for rapid installation, free of adjustment of the articulated locking assembly, the procedure is as follows: - a counterplate (10), stiffened by two corner gussets ( 18), pierced with two threaded holes used to house the adjusting screws (13), is positioned on the rear frame of the hopper and fixed to civil engineering, either by welding on the original metal frame or by sealing in the facing of the opening, - then the locking slabs (la) and (lb) are put in place and the assembly, metal plate (4) and its hinge plate (8) which also carries the lock block of the lock bolt ( 9), is presented in the space remaining to be closed: the plate (8), which carries two lights for passage of the adjustment and support screws (13) on the plywood, is adjusted, blocked then definitively secured by welding with the plywood (10).

En référence aux figures 1 et 2 et selon la nécessité de venir fixer la goulotte articulée de récupération des corps étrangers en sous face des opercules de manoeuvre des dalles, celles-ci sont enlevées, les cornières servant aux appuis latéraux (16) sont fixées par pistolet de scellement sur les parements de l'ouverture puis l'ensemble de la goulotte en U (5) avec ses barres transversales d'appui (15) et son sabot (14) d'articulation et de blocage en position de relevage, est mis en place, les barres transversales reposant sur leurs appuis. I1 ne reste plus alors qu'à fixer le sabot d'articulation par pistolet de scellement sur le parement avant.  With reference to FIGS. 1 and 2 and according to the need to fix the articulated chute for recovering foreign bodies on the underside of the slab maneuvering covers, these are removed, the angles used for the lateral supports (16) are fixed by sealing gun on the faces of the opening then the whole of the U-shaped chute (5) with its transverse support bars (15) and its hinge (14) for articulation and locking in the lifting position, is installed, the crossbars resting on their supports. I1 then remains only to fix the articulation shoe by sealing gun on the front facing.
