Abstract

The invention relates to a device intended for equipping structures subjected to variations in dimensions, generally bridges, with expansion joints. This device consists of two openworked metal parts 1 placed next to each other and fixed or anchored rigidly on either side of the joint and used to hold a central elastomer member 2 by snap-fitting, the locking of which is ensured by a snap-ring. By virtue of its design, the invention makes it possible to take up a greatly reduced area of the road, to increase in this way the safety of the users, to reduce the quantities of products employed without, as a result, reducing its base surface required for its stability, to have virtually no slippery surface on the road, to facilitate the inspection and maintenance of the groove separating the structures, and to enable the sealing member to be easily changed without having to dismantle mechanical parts.

DESCRIPTION
JOINT FOR EXPANSION OF CONSTRUCTION WORK
REDUCED AND CONTINUOUSLY INTERCHANGEABLE SEAL
The present invention relates to a device intended to fill the void in the expansion joints of road and building works, while allowing movements due to dimensional variations caused by expansion, shrinkage or any other external stresses.
The device ensures continuity of road surface, sealing, reinforcement of the lips of the histus to resist heavy traffic without hampering the various movements of the structure.

Des systèmes répondant à ces fonctions existent déjà, mais ils comportent plusieurs incouvénients, soit leur conception ne permet pas une fixation par un organe liant le vieux béton à le pièce St dans ce cas la tenue du système se fait par simple adhérence, soit sus les pièces mises en oeuvre nécessitent de réserver un espace de coulage entre le joint et la chaussée augmentant ainsi inutilement l'emprise sur la route, soit que les pièces assurant l'étanchéité ne sont pas continues, soit qu'elles sont fixées par des organes mécaniques en contact avec la circulation et susceptibles de se desserrer, soit qu'elles sont encliquetées de manière latérale rendant difficile leur mise en oeuvre quand le joint est fermi, soit qu'elles ne sont pas accessibles et difficilement nettoyables. Systems meeting these functions already exist, but they have several drawbacks, either their design does not allow a fixing by a member linking the old concrete to the part St in this case the holding of the system is done by simple adhesion, either on parts used require reserving a pouring space between the joint and the roadway thus unnecessarily increasing the footprint on the road, either because the parts ensuring the sealing are not continuous, or because they are fixed by mechanical members in contact with traffic and liable to loosen, either because they are snapped sideways making it difficult to use when the seal is closed, or because they are not accessible and difficult to clean.

Le dispositif selon l'invention est constitué de deux pièces métalliques, en troncons de un mètre environ, ajouré@s, obtenues par mécanosoudure ou fonderie (1) Fig 1 . Ces pièces sont fixées ou scellées à la structure dans l'épaisseur du revêtement routier, en vis à vis, de part et d'autre de la feuillure séparant les ouvrages; elles servent à renforcer les bords extrèmes du joint et à assurer la fixation étanche du profilé central en élastomère (2) Fig 1
Les pinces métalliques (1) Fig 1 , sont concues pour offrir un maximum de résistance mécanique dans l'espace le plus réduit possible
Constitues d'une ossature ajourée, les éléments (3) Fig 2 en appui sur l'ouvrage sont situées plus bas que le niveau de circulation des véhicules de telle sorte que la partie émergeant se trouve extrèmement réduite
Les membrures (3) et (5) Fig 2 constituent des raidisseurs qui permettent de réduire à 3cms l'épaisseur des éléments, ce qui constitue un avantage notable, compte tenu de la tendance qu'ont les revâtements routiers à diminuer en épasisseur .
The device according to the invention consists of two metal parts, in sections of about one meter, perforated @ s, obtained by mechanic welding or foundry (1) Fig 1. These parts are fixed or sealed to the structure in the thickness of the road surface, facing each other, on either side of the rebate separating the works; they serve to reinforce the extreme edges of the joint and to ensure the watertight fixing of the central elastomer profile (2) Fig 1
The metal clamps (1) Fig 1, are designed to offer maximum mechanical resistance in the smallest possible space
Consisting of an openwork frame, the elements (3) Fig 2 resting on the structure are located lower than the level of vehicle traffic so that the emerging part is extremely reduced
The frames (3) and (5) Fig 2 constitute stiffeners which make it possible to reduce the thickness of the elements to 3 cm, which constitutes a notable advantage, taking into account the tendency of road surfaces to decrease in thickener.

D'autre part, l'ossature ajourée (1) Fig 1 autorise plusieurs modes de fixation des éléments à l'ouvrage telles que 2
- Fixation par scellement à l'aide de mortiers spéciaux . Les jours permettant en plus de déverser le produit de scellement au travers des pinces métalliques, sans qu'il soit nécessaire de réserver un espace de coulage entre ces pièces métalliques et la chaussée
- Fixation par vis en acier haute résistance ancrées dans des douilles métalliques
- Fixation par des tiges filetées en acier haute résistance, scellées dans des trous forés sans qu'il soit nécéssaire de prévoir des aménagements spéciaux sur l'ouvrage puisque les possibilités de déplacement de ces fixations sont multiples du fait de la forme des jours, permettant ainsi d'éviter dans tous les cas les armatures ds l'ouvrage
Les membrures (5) Fig 2 remontent à fleur de la surface circulée, elles constituent un renfort qui limite I'ornièrage au droit du joint et forment une défense protégeant de l'action des chasse.- neige dans les régions montagneuses . L'ossature (i) Fig 1 permet,du fait qu'elle soit ajourée, de réduire les côuts du produit par un gain de matière et un gain de poids appréciable au transport
Le dispositif est en trois parties . La partie centrale (2) Fig 1 qui constitue Vétanchéité continue, est un profilé en élastomère qui s'encliqubte dans les rainures d'ancrage (6) Fig 2 .La fixation est assurée par la réalisation d'une forme adéquate des extrémités du profilé (7) Fig 2, permettant son introduction aisée- dans la rainure (6) Fig 2 ,et son blocage
Le verrouillage de l'ancrage du profilé d'élastomère (2) Fig 1 , est garanti par la mise en place (4) Fig 2 d'une résine formant jonc ou l'enfilage dans l'orifice tubulaire (9) Fig 2 , d'une tige métallique ou plastique
Cette conception permet de ne pas avoir d'organe de serrage en contact avec la circulation tout en étant pourvu d'une sécurité de verrouillage
L'encliquetage du profilé en élastomère (2) Fig 1 peut se faire auprès la fixation des pièces (1) Fig 1 posées en vis à vis sans qu'il soit nécessaire de procéder à un démontage meme partiel des pièces mises en place, et permet un démontage aisé des coffrages de pose ainsi qu'une vérification et un nettoyage,- sur toute sa hauteur,de la feuillure séparant les ouvrages
Pour les joints de grande ouverture les pièces métalliques (1) Fig 1 peuvent être munies de dents ou de saillies supportant par en dessous ou protégeant par en dessus le profilé continu en élastomère (2) Fig 1
On the other hand, the openwork frame (1) Fig 1 allows several methods of fixing the elements to the structure such as 2
- Fixing by sealing with special mortars. On days which allow, in addition, to pour the sealant through metal clips, without the need to reserve a pouring space between these metal parts and the roadway
- Fixing by high resistance steel screws anchored in metal sockets
- Fixing by threaded rods in high resistance steel, sealed in drilled holes without it being necessary to provide special arrangements on the structure since the possibilities of displacement of these fixings are multiple due to the shape of the days, allowing thus avoiding in all cases the armatures of the structure
The frames (5) Fig 2 rise flush with the circulated surface, they constitute a reinforcement which limits the rutting to the right of the joint and form a defense protecting from the action of snow plows in mountainous regions. The framework (i) Fig 1 allows, because it is perforated, to reduce the costs of the product by saving material and appreciable weight gain during transport
The device is in three parts. The central part (2) Fig 1 which constitutes the continuous seal, is an elastomer profile which snaps into the anchoring grooves (6) Fig 2. The fixing is ensured by making an adequate shape of the ends of the profile (7) Fig 2, allowing its easy introduction into the groove (6) Fig 2, and its blocking
The locking of the anchoring of the elastomer profile (2) Fig 1, is guaranteed by the installation (4) Fig 2 of a resin forming a rod or the threading in the tubular orifice (9) Fig 2, a metal or plastic rod
This design makes it possible not to have a clamping member in contact with the circulation while being provided with a locking security
The snap-fastening of the elastomer profile (2) Fig 1 can be done with the fixing of the parts (1) Fig 1 placed facing each other without it being necessary to disassemble even partially the parts put in place, and allows easy dismantling of laying formwork as well as verification and cleaning, - over its entire height, of the rebate separating the works
For large opening joints the metal parts (1) Fig 1 can be provided with teeth or projections supporting from below or protecting from above the continuous elastomer profile (2) Fig 1
