Abstract
Description
La présente invention a pour objet des glissières de sécurité en bois ronds destinées à être placées dans tous les lieux où les véhicules sont susceptibles de s'écarter volontairement ou accidentellement des voies qui leur sont affectées, notamment le long des routes et autoroutes ou en lisière des parcs de stationnement. Le secteur technique est donc celui de la construction des dispositifs de sécurité routiers.The present invention relates to round wooden safety barriers intended to be placed in all places where vehicles are likely to deviate voluntarily or accidentally from the lanes assigned to them, in particular along roads and motorways or on the edge parking lots. The technical sector is therefore that of the construction of road safety devices.
On connaît le système mixte ayant fait l'objet d'un brevet d'invention publié sous le N° FR-B-2 663 968.We know the mixed system which was the subject of a patent for invention published under the number FR-B-2 663 968.
La présente invention a pour objet la réalisation de lisses en bois rond armées de fer encastré alliant avantageusement les propriétés complémentaires de ces deux matériaux. L'invention permet un procédé de montage et de fabrication qui augmente la fiabilité des systèmes connus et diminue sensiblement le coût de fabrication, de transport et de mise en oeuvre. Il s'adapte avantageusement à toutes les situations de montage : courbes, haut de côte, fin de glissière.The present invention relates to the production of smooth wooden round armored iron recessed advantageously combining the complementary properties of these two materials. The invention allows a mounting and manufacturing method which increases the reliability of known systems and significantly reduces the cost of manufacturing, transport and implementation. It adapts advantageously to all mounting situations: curves, top of hill, end of slide.
Les problèmes à résoudre sont les suivants :
- 1. Le bois est un matériau naturel hétérogène susceptible de présenter des points de moindre résistance et sous le choc d'un véhicule il plie peu, mais peut casser. Par contre le coefficient de frottement fer bois est très important et c'est une propriété qu'on mettra à profit pour freiner les véhicules.
- 2. Les supports métalliques sont inesthétiques.
- 3. Les supports métalliques doivent être écartés de la lisse pour éviter le choc avec le véhicule. Un écarteur est donc nécessaire.
- 4. Les procédés connus sont difficiles à monter et font appel à de multiples pièces. Il est donc nécessaire de simplifier et de rendre le montage polyvalent.
- 1. Wood is a heterogeneous natural material likely to present points of less resistance and under the shock of a vehicle it bends little, but can break. On the other hand, the coefficient of iron-on-wood friction is very important and it is a property that we will take advantage of to brake vehicles.
- 2. The metal supports are unsightly.
- 3. The metal supports must be moved away from the arm to avoid impact with the vehicle. A retractor is therefore necessary.
- 4. The known methods are difficult to assemble and use multiple parts. It is therefore necessary to simplify and make the assembly versatile.
Pour résoudre ces problèmes, les solutions suivantes ont été trouvées :
- 1. Les lisses sont renforcées du côté opposé à la route par un fer profilé encastré dans la lisse bois. Les ailes du profilé sont logées dans deux fentes parallèles à l'axe de la lisse et sont ainsi invisibles.
- 2. L'écarteur est constitué d'un bois rond placé verticalement entre le support métallique et la lisse. De cette façon le support est caché mais l'écarteur s'arrête à 5 cm du sol pour éviter tout risque de pourriture. Pour les mêmes raisons l'extrémité supérieure est coupée en biais.
- 3. Pour éviter de gêner le glissement du véhicule le long de la glissière, l'écarteur peut avantageusement tourner autour de l'axe du boulon de fixation. La structure est renforcée par un cerclage métallique galvanisé pour éviter tout risque de projection.
- 4. Pour faciliter le montage les éclisses métalliques de fixation opposées à la route sont avantageusement solidaires du fer profilé encastré et montés en usine. Toutes les éclisses sont avantageusement munies de trous oblongs permettant le montage dans toutes les situations. Selon la nécessité les éléments de la lisse horizontale seront de deux ou quatre mètres. Ils peuvent aussi être montés sur des supports existants en remplacement des glissières de sécurité métalliques, sans changer le support et éventuellement sans changer l'écarteur métallique existant.
- 1. The beams are reinforced on the side opposite the road by a profiled iron embedded in the wood beam. The wings of the profile are housed in two slots parallel to the axis of the heald and are thus invisible.
- 2. The spacer consists of a round wood placed vertically between the metal support and the rail. In this way the support is hidden but the spacer stops at 5 cm from the ground to avoid any risk of rot. For the same reasons the upper end is cut at an angle.
- 3. To avoid interfering with the sliding of the vehicle along the slide, the spacer can advantageously rotate around the axis of the fixing bolt. The structure is reinforced by a galvanized metal band to avoid any risk of projection.
- 4. To facilitate assembly, the metal fastening plates opposite the road are advantageously secured to the recessed profiled iron and fitted in the factory. All the fishplates are advantageously provided with oblong holes allowing mounting in all situations. Depending on the need, the elements of the horizontal rail will be two or four meters. They can also be mounted on existing supports to replace the metal safety barriers, without changing the support and possibly without changing the existing metal spacer.
Le dispositif de sécurité selon l'invention peut être mis en place avec les matériels disponibles dans les entreprises posant habituellement des glissières métalliques, sans formation particulière du personnel.The safety device according to the invention can be put in place with the materials available in companies that usually install metal slides, without special training for personnel.
Le dispositif comporte un nombre limité de pièces standard
- piquets métalliques standard
- écarteurs bois selon invention
- lisses selon invention de quatre mètres pour lignes droites et courbes ou de deux mètres pour usages spéciaux et courbes serrées.
- boulons de fixation TRCC 16 x 200 avec écrou à épaulement ou écrou et rondelle large
