Description

1 DISPOSITIF DE SUPPRESSION DES APPUIS PRECAIRES POUR MATS ET BRACONS. LaDEVICE FOR SUPPRESSING PRECARIOUS SUPPORT FOR MATS AND BRACONS. The

présente invention a pour objet un dispositif de suppression des appuis précaires pour mâts et bracons. Les mâts et bracons destinés à supporter les antennes téléphoniques ou autres sont maintenus dans des éléments de support. Les personnes chargées des interventions sur les antennes utilisent ces éléments de suppot comme appui, ce qui présente un danger réel d'une part en raison du fait que ces éléments ne sont pas adaptés pour supporter le poids d'une personne et les garde-corps prévus autour des mâts pour garantir la sécurité du personnel intervenant n'auront plus alors la hauteur règlementaire. Les inventeurs ont trouvé qu'il était possible de sécuriser ces éléments en plaçant autour des mâts ou bracons, au-dessus de la face supérieure de l'élément support un élément creux à paroi inclinée.  The present invention relates to a device for eliminating precarious supports for poles and masts. Masts and bracons for supporting telephone or other antennas are held in support elements. The persons in charge of the interventions on the antennas use these elements of suppot as support, which presents a real danger on the one hand because of the fact that these elements are not adapted to support the weight of a person and the railings provided around the masts to ensure the safety of the personnel involved will no longer have the regulatory height. The inventors have found that it was possible to secure these elements by placing a hollow element with an inclined wall above the upper face of the support element around the masts or bracons.

Ainsi, la présente invention porte sur un dispositif pour mâts et bracons comprenant au moins un élément plan entourant le mât ou bracon, ledit élément plan étant incliné, son extrémité inférieure étant en appui sur l'élément support du mât ou bracon et l'extrémité supérieure se trouvant à proximité du mât ou bracon. Selon un premier mode de réalisation, ledit élément plan forme un tronc de cône ouvert sur une partie de sa circonférence. Selon un autre mode de réalisation, ledit élément 30 plan forme trois faces d'un tronc de pyramide à base carré. 2903443 2 Le fait qu'une partie du dipositif reste ouverte permet un accès facile aux cables. En outre lorsque le dispositif est utilisé pour un bracon, celui-ci est placé dans la zone ouverte, comme illustré sur la figure 3. Il 5 est bien évident que dans le cas d'un bracon le dispositif n'est pas nécessairement sous forme de cône ou pyramide tronqué. Le dispositif peut être maintenu autour du mât par un collier entourant ledit mât et s'appuyant sur 10 l'extrémité supérieure du plan incliné. Afin de dissuader plus encore les personnes de monter sur le dispositif, celui-ci est réalisé en un matériau peu résistant et les parois sont inclinées. Ainsi la paroi inclinée peut être réalisée en polymère ou 15 en tôle fine, de préférence en polyéthylène haute densité ou en polyuréthane dur ou en tôle d'aluminium. L'angle formé entre l'axe du mât et la paroi interne inclinée est compris entre 10 et 60 , de préférence entre 20 et 45 . 20 Il est également possible de fragiliser le dispositif afin que si une personne prenait appui sur celui-ci il se plierait ou se casserait immédiatement. Pour ce faire, le plan incliné comporte au moins une découpe. Cette découpe peut être présente sur chacune des 25 faces de la pyramide. Elle peut prendre la forme d'un motif décoratif ou d'un élément d'identification, par exemple les lettres d'une marque. Ces découpes permettent également le contrôle visuel des boulonneries et/ou de l'ancrage du mât ou du bracon.  Thus, the present invention relates to a device for masts and bracons comprising at least one plane element surrounding the mast or bracon, said plane element being inclined, its lower end being in abutment on the support element of the mast or bracon and the end upper located near the mast or bracon. According to a first embodiment, said planar element forms a conical frustum open over part of its circumference. According to another embodiment, said planar element forms three faces of a truncated pyramid with a square base. 2903443 2 The fact that part of the device remains open allows easy access to the cables. Furthermore, when the device is used for a breast, it is placed in the open zone, as illustrated in FIG. 3. It is obvious that in the case of a breast the device is not necessarily in the form of a breast. cone or truncated pyramid. The device can be held around the mast by a collar surrounding said mast and resting on the upper end of the inclined plane. In order to further deter people from getting on the device, it is made of a weak material and the walls are inclined. Thus the inclined wall can be made of polymer or thin sheet, preferably high density polyethylene or hard polyurethane or aluminum sheet. The angle formed between the axis of the mast and the inclined inner wall is between 10 and 60, preferably between 20 and 45. It is also possible to weaken the device so that if a person leaning on it it would bend or break immediately. To do this, the inclined plane comprises at least one cut. This cut can be present on each of the 25 faces of the pyramid. It can take the form of a decorative pattern or an identifying element, for example the letters of a mark. These cuts also allow the visual control of the bolts and / or the anchoring of the mast or the bracon.

L'invention porte également sur un procédé de suppression des appuis précaires dus à l'élément support de mât ou bracon caractérisé par le fait que l'on fixe 2903443 3 sur la partie supérieure dudit élément support de mât ou bracon un dispositif tel que décrit précédemment. Lorsque le dispositif est destiné à être utilisé pour un mât, celui-ci est disposé suivant l'axe central 5 dudit dispositif. Lorsque le dispositif des destiné à être utilisé pour un bracon, celui-ci est disposé de telle sorte qu'il passe par la partie libre du tronc de cône ou la face libre de la pyramide à base carrée.  The invention also relates to a method for eliminating precarious supports due to the mast or brace support element, characterized in that a device as described in FIG. 2 is attached to the upper part of said mast support member or a brace member. previously. When the device is intended to be used for a mast, it is arranged along the central axis 5 of said device. When the device intended to be used for a bracon, it is arranged so that it passes through the free portion of the truncated cone or the free face of the square-based pyramid.

10 L'invention sera mieux comprise à l'aide des dessins annexés sur lesquels les figures 1 et 2 représentent une vue générale d'un dispositif de l'invention utilisé pour un mât selon deux angles différents et la figure 3 represente une vue générale d'un dispositif de 15 l'invention utilisé pour un bracon. Sur les figures 1 et 2 est représenté un dispositif conforme à l'invention installé autour d'un mât 2. Le mât qui comporte en sa partie inférieure une plaque de fixation 7, est placé sur un élément support 3 comprenant 20 une partie plane carrée 4 venant s'appuyer sur la toiture où le mât doit être installé. Cette partie plane est surmontée en sa partie centrale par un élément parallèlépipédique 5 sur lequel est fixée la plaque de fixation 7 du mât 2. L'élément support 3 est fixé sur la 25 toiture en quatre points placés aux coins de la partie plane carrée 4. Sur la face supérieure de la plaque de fixation 7 est fixé un élément de protection 6 en forme de pyramide tronquée à base carrée, ledit élément 6 comportant uniquement trois plans inclinés 9. Le haut de 30 l'élément pyramidal tronqué est maintenu par un cerclage 10 disposé autour du mât 2.The invention will be better understood with the aid of the accompanying drawings in which FIGS. 1 and 2 show a general view of a device of the invention used for a mast from two different angles and FIG. a device of the invention used for a bracon. Figures 1 and 2 show a device according to the invention installed around a mast 2. The mast which comprises in its lower part a fixing plate 7, is placed on a support member 3 comprising 20 flat square part 4 coming to rest on the roof where the mast must be installed. This flat part is surmounted in its central part by a parallelepipedal element 5 on which is fixed the fixing plate 7 of the mast 2. The support element 3 is fixed on the roof at four points placed at the corners of the flat square part 4 On the upper face of the fixing plate 7 is fixed a square-base truncated pyramid shaped protection element 6, said element 6 having only three inclined planes 9. The top of the truncated pyramidal element is held by a strapping 10 arranged around the mast 2.

2903443 4 Sur la figure 3 est représenté un dispositif selon l'invention adapté pour un bracon. Ainsi, un bracon 11 est disposé sur un élément parallélépipédique support 12 dont la face supérieure 14 5 constitue une plaqque de fixation du bracon. Sur cet élément support est fixé un élément de protection 13 en forme de pyramide tronquée à base carrée placé sur la partie supérieure de l'élément support 12. Ledit élément 13 comporte uniquement trois plans inclinés 15, la partie 10 libre de la pyramide permettant le passage du bracon. Sur la figure 3 est également représenté le garde-corps. Ainsi, on voit bien que si un homme grimpe sur l'élément support 12 la hauteur du garde-corps sera alors insuffisante pour retenir sa chute. 15 20 25In Figure 3 is shown a device according to the invention adapted for a bracon. Thus, a brace 11 is disposed on a support parallelepipedic element 12 whose upper face 14 5 constitutes a plate for fixing the bracon. On this support element is fixed a truncated pyramid-shaped protection element 13 with a square base placed on the upper part of the support element 12. Said element 13 comprises only three inclined planes 15, the free part 10 of the pyramid allowing the passage of the bracon. In Figure 3 is also shown the guardrail. Thus, it is clear that if a man climbs on the support member 12 the height of the guardrail will then be insufficient to retain its fall. 15 20 25
