Abstract

Protective system for carpenters, roofers and zinc workers while they are working on the building and repair of roofs. The guard rail includes a U-shaped rider 1 consisting of three tubes welded at right angles or of one arch-shaped tube only. One end of a branch 2 of the rider 1 is fitted with a clamp 3 for straddling over the underside of the rafter. The stirrup part 4 of the clamp 3 is placed transversely relative to the rider plane and carries at the two ends of its branches 4a and 4b means for anchoring 5 into a lateral face of the rafter and a clamping screw 6 also carrying means for anchoring 7 into the opposite face of the rafter. The other branch of the rider 10 constitutes an upright which carries placements 11 for the mounting of boards forming the guard rail barrier. The internal face of the horizontal portion of the stirrup part 4 is welded onto the end of one branch 2 of the rider. A plate 8 which is fillet-welded onto the bottom of the horizontal portion of the stirrup part 4 and which bears against the frontal face of the rafter prevents the rider 1 from pivoting. This system is easily mounted and demounted and enables the works to be completed without demounting the guard rail.

Description

La présente invention se rapporte à un garde corps de protection pour les travailleurs opérant sur des toitures comportant une charpente en bois à chevrons apparents.The present invention relates to a protective body guard for workers operating on roofs comprising a wooden frame with visible rafters.

On connait de différents systèmes protégeant les charpentiers, les couvreurs et les zingueurs au cours de leurs travaux de construction et de réfection de toitures.We know of different systems protecting carpenters, roofers and zinc workers during their construction and roof repair work.

Un de ces systèmes scellés au mur de l'édifice nécessite le percement du mur pour la pose des cavaliers fixés à travers le mur. D'autres systèmes comportent une suspension des cavaliers au moyen d'une élingue à un élément de la charpente. Les deux systèmes ont pour l'inconvénient la nécessité de refaire les murs et de démonter les organes d'accrochage au mur ou à la charpente en fin de chantier et, par conséquent, comportent des opérations longues et coûteuses.One of these systems sealed to the wall of the building requires the drilling of the wall for the installation of jumpers fixed through the wall. Other systems include a suspension of the jumpers by means of a sling to an element of the frame. The two systems have the disadvantage of having to redo the walls and dismantle the fastening members to the wall or to the frame at the end of the work and, consequently, involve long and costly operations.

Selon un autre système connu, le système est accroché sur la partie supérieure du chevron et maintenu en équilibre au moyen d'une béquille prenant appui sur le mur. Ce dernier système présente également un inconvénient, car le mode d'accrochage par dessus le chevron ne permet pas d'achever la couverture ni de poser des dalles avant le démontage des garde corps.According to another known system, the system is hung on the upper part of the rafter and kept in balance by means of a crutch resting on the wall. This latter system also has a drawback, because the method of hanging over the rafter does not allow the roof to be completed or the tiles to be laid before the guardrails are dismantled.

L'achèvement des travaux doit donc s effectuer avec le port obligatoire d'un équipement encombrant3 tel que baudrier de sécurité.The completion of the work must therefore be carried out with the compulsory wearing of bulky equipment3 such as a safety harness.

Le garde corps faisant l'ob3eb de l'invention permet de remédier aux in convénients signalés, car la pose est simple et ne nécessite aucune préparation, telle que le perchage des murs ou mise en place des élingues, tandis que le garde corps peut rester en place jusqu'à l'achèvement des travaux.The bodyguard making the ob3eb of the invention makes it possible to remedy the inconveniences reported, because the installation is simple and does not require any preparation, such as perching the walls or setting up slings, while the bodyguard can remain in place until completion of the work.

Le garde corps de protection pour travailleurs opérant sur des toitures comportant une charpente en bois à chevrons apparents selon l'invention, est caractérisé en ce qu'il comprend au moins un cavalier en U, dont une branche se termine par une extrémité munie d'un serre-joint pour l'engagemment à cheval sur le chevron, dont l'étrier transversal par rapport au plan du cavalier porte aux deux extrémités de ses branches, respectivement, des moyens d'ancrage dans une face latérale du chevron et une vis de serrage dont l'extrémité porte également des moyens d'ancrage dans la face latérale opposée du chevron, l'autre branche du cavalier constituant un montant portant des moyens pour le montage des planches formant la barrière du garde corps.The protective body guard for workers operating on roofs comprising a wooden frame with visible rafters according to the invention, is characterized in that it comprises at least one U-shaped jumper, one branch of which ends at one end provided with a clamp for engagement straddling the rafter, the transverse stirrup relative to the plane of the rider carries at the two ends of its branches, respectively, anchoring means in a lateral face of the rafter and a screw tightening whose end also carries anchoring means in the opposite lateral face of the rafter, the other branch of the rider constituting an upright carrying means for mounting the boards forming the barrier of the bodyguard.

De préférence, l'extrémité de la branche du cavalier est soudée à la face inférieure de la partie horizontale de l'étrier du serre-joint.Preferably, the end of the rider's branch is welded to the underside of the horizontal part of the clamp clamp.

Le cavalier en U peut être constitué de trois tubes de section ronde ou carrée soudés à angle droit, il peut également être constitué d'un seul tube formé en arc de cercle. Dans les deux cas, le cavalier comporte à ses extrémités deux branches droites, une plus courte portant le serre-joint, l'autre plus longue portant les planches formant barrière.The U-shaped jumper can be made up of three tubes of round or square section welded at right angles, it can also be made up of a single tube formed in an arc. In both cases, the rider has two straight branches at its ends, one shorter carrying the clamp, the other longer carrying the boards forming a barrier.

L'étrier du serre-joint est en profilé métallique, par exemple en T. Des moyens sont prévus pour empêcher le pivotement du cavalier autour de l'axe passant par les points d'ancrage du serre-joint. Ces moyens sont constitués par exemple par une plaque soudée à angle sur le fond de la partie horizontale de l'étrier et destinée à s'appliquer sur la face frontale du chevron. Lorsque les branches du cavalier sont reliées par une partie horizontale, ces moyens peuvent être consitués par un fourreau soudé à la partie horizontale du cavalier et par une béquille susceptible de coulisser à l'intérieur du fourreau pour une prise d'appui de son extrémité sur le mur du bâtiment et d'être bloquée en position au moyen d'une goupille.The clamp clamp is made of metal profile, for example in T. Means are provided to prevent pivoting of the jumper around the axis passing through the anchor points of the clamp. These means consist for example of a plate welded at an angle to the bottom of the horizontal part of the stirrup and intended to be applied to the front face of the rafter. When the arms of the rider are connected by a horizontal part, these means can be constituted by a sheath welded to the horizontal part of the rider and by a crutch capable of sliding inside the sheath for a grip on its end on the wall of the building and be locked in position by means of a pin.

Figures 4 and 5 are, respectively, side and front views
of the body guard according to an alternative embodiment.

Le cavalier du garde corps 1 est un profilé de section ronde ou carré en forme de U, dont une branche 2 plus courte porte soudé à son extrémité un serre-joint 3, transversal par rapport au plan du cavalier 1, comportant un étrier 4 formé d'un profilé en T. Une des extrémité 4a de l'étrier est munie d'une pointe 5 tournée vers l'intérieur duserre-joint 3, tandis que l'autre extrémité 4b est percée et taraudée pour permettre le passage d'une vis de serrage 6, dont l'extrémité porte également une pointe 7. Lors du serrage, les deux pointes 5 et 7 s'enfonceront de part et d'autre du chevron et constitueront un bon point d'ancrage.The rider of the bodyguard 1 is a profile of round or square U-shaped section, of which a shorter branch 2 carries at its end welded a clamp 3, transverse to the plane of the rider 1, comprising a stirrup 4 formed of a T-profile. One of the ends 4a of the stirrup is provided with a point 5 turned towards the inside of the clamp 3, while the other end 4b is drilled and tapped to allow the passage of a clamping screw 6, the end of which also carries a point 7. When tightening, the two points 5 and 7 will sink on either side of the rafter and will constitute a good anchoring point.

Sur la face inférieure de la partie horizontale de l'étrier 4 est soudée à angle oblique une plaque 8, dont l'angle qu'elle fait avec la horizontale épouse l'angle oblique du chevron. La plaque 8 a pour rôle d'empêcher tout pivotement de l'étrier 4 autour de l'axe passant par les points d'ancrage 5 et 7 du serre-joint.On the underside of the horizontal part of the stirrup 4 is welded at an oblique angle a plate 8, the angle of which it makes with the horizontal follows the oblique angle of the rafter. The role of the plate 8 is to prevent any pivoting of the stirrup 4 around the axis passing through the anchor points 5 and 7 of the clamp.

L'étrier 4 du serre-joint est rendu solidaire du cavalier 1 par soudure de l'extrémité de la branche 2 du cavalier sur la face inférieure de la partie horizontale de l'étrier 4.The stirrup 4 of the clamp is made integral with the rider 1 by welding the end of the branch 2 of the rider on the underside of the horizontal part of the stirrup 4.

L'autre branche plus longue 10 du cavalier constitue un montant, à la face intérieure duquel sont fixés des logements 11 pour des planches servant de barrières du garde corps. The other longer branch 10 of the rider constitutes an upright, to the inner face of which are fixed housings 11 for boards serving as barriers of the bodyguard.

Les branches courte 2 et longue 10 du cavalier sont reliées entre elles par une partie horizontale 9. Du fait de l'existence de la branche courte 2, la barre horizontale 9 se trouve en contre-bas par rapport à l'extrémité du chevron et ménage un dégagement entre le bord de la toiture et la barrière de protection Ce dégagement permet de terminer entièrement la couverture du toit et la pose des dalles avant le démontage du garde corps.The short 2 and long 10 branches of the rider are connected together by a horizontal part 9. Due to the existence of the short branch 2, the horizontal bar 9 is located below against the end of the rafter and provides a clearance between the edge of the roof and the protective barrier This clearance allows the roof covering and the installation of the tiles to be completed before dismantling the railing.

Selon une autre variante du système proposé (figures 4 et 5), on fixe de la même manière le cavalier 1 sur l'étrier 4 en ménageant un dégage ment suffisant par rapport au bord du toit, mais en supprimant la plaque B. According to another variant of the proposed system (Figures 4 and 5), the rider 1 is fixed in the same way on the stirrup 4 while providing sufficient clearance relative to the edge of the roof, but by removing the plate B.

On soude alors un morceau de tube faisant fonction de fourreau 16 sur la partie horizontale 9 du cavalier, dans lequel coulisse une barre d'appui ou béquille 17, dont l'extrémité 17a est. destinée à prendre appui sur le mur de l'édifice. La barre 17 et le fourreau 16 étant munis de perçages espacés, un système de goupille 18 permet de bloquer en position ba barre et le forreau. La rotation du serre-joint 3 autour ses points de fixation au chevron est ainsi supprimée. A piece of tube acting as a sheath 16 is then welded on the horizontal part 9 of the rider, in which slides a support bar or crutch 17, the end of which 17a is. intended to rest on the wall of the building. The bar 17 and the sheath 16 being provided with spaced holes, a pin system 18 makes it possible to block in position ba barre and the sheath. The rotation of the clamp 3 around its attachment points to the rafter is thus eliminated.

La pose du garde corps selon l'invention s'effectue de façon simple. On place le serre-joint à cheval par en dessous le chevron, et dans le cas de la réalisation représentée aux figures 1 à 3, en applique la plaque 8 contre la face inférieure oblique du chevron @n opère le serrage au moyen de la vis 6, jusqu'à ce que les pointes 5 et 7 rentrent profondément dans le bois. On place des planches formant barrière dans les logements il et d'autres planches formant le plancher.The installation of the body guard according to the invention is carried out in a simple manner. We place the clamp on horseback below the rafter, and in the case of the embodiment shown in Figures 1 to 3, apply the plate 8 against the oblique underside of the rafter @n tightens by means of the screw 6, until the points 5 and 7 go deep into the wood. Plates forming a barrier are placed in the housings II and other boards forming the floor.

Dans le cas de la variante selon les figures 4 et 5, on ajuste la longueur de la béquille 17 que l'on bloque dans le fourreau 16 au moyen de la goupille 18.In the case of the variant according to FIGS. 4 and 5, the length of the stand 17 is adjusted and blocked in the sheath 16 by means of the pin 18.

Le montant 10 peut être démontable en forme de montant s'emmanchant sur la partie inférieure du cavalier
Les avantages du système selon l'invention découlent principalement du mode de fixation du cavalier au moyen de 1 l'étrier du serre-joint que 1 on plage par en dessous le chevron Ainsi la pose est Grès simple et ne nécessite aucune préparation, telle que perçage des murs ou mise en place des élingues. En outre, le système peut rester n place jusqu'à l'achèvement de travaux de couverture. Le système de sécurité peut servir sans préparation particulière dans les opérations de réfection de toitures existantes.The upright 10 can be dismantled in the form of an upright which fits onto the lower part of the rider
The advantages of the system according to the invention derive mainly from the method of fixing the rider by means of 1 the clamp clamp that 1 is beached from below the rafter. The installation is simple sandstone and requires no preparation, such as drilling walls or installing slings. In addition, the system can remain in place until completion of roofing work. The security system can be used without special preparation in existing roof repair operations.

Le temps employé pour la pose et la dépose du garde corps est très court et permet de réaliser une économie non négligeable
L'invention n'est pas limitée aux formes de réalisation décrits précédemment, elle est susceptible de nombreuses variantes, notamment en ce qui concerne la configuration et la forme du profilé utilisé pour la réalisation du cavalier, du serre-joint et du montant servant à loger les planches formant la barrière. The time used for the installation and removal of the body guard is very short and allows a significant saving
The invention is not limited to the embodiments described above, it is susceptible of numerous variants, in particular as regards the configuration and the shape of the profile used for the production of the jumper, the clamp and the upright used to house the boards forming the barrier.
