DESCRIPTION
La présente invention concerne un dispositif et procédés d'assemblages de poutrelles enrobées préfabriquées pour planchers ou ouvrages d'art de génie civil.DESCRIPTION
The present invention relates to a device and methods for assembling prefabricated coated beams for floors or civil engineering structures.
Les poutrelles en acier sont utilisées en particulier pour les tabliers des ponts, elles offrent l'avantage par leurs ailes d'offrir un appui aux coffrages perdus et permettent de s'affranchir de la réalisation d'un cintre. Steel beams are used in particular for decks of bridges, they offer the advantage by their wings of offering support to the lost formwork and allow to overcome the realization of a hanger.
Ces ponts sont le plus souvent de construction économique, d'une très grande résistance, très fiables, utilisés par la
Société Nationale des Chemins de Fer, le ministère de l'Equipement, les sociétés concessionnaires des autoroutes et autres collectivités.These bridges are most often of economical construction, of a very high resistance, very reliable, used by
National Railway Company, the Ministry of Equipment, motorway concession companies and other communities.
Le dispositif et procédé selon l'invention apporte l'avantage de réaliser en usine la préfabrication et de s'affranchir de toutes les contraintes d'une coulée en place à plusieurs mètres de hauteur, coulée trop souvent réalisée dans des conditions climatiques peu favorables, donc de maîtrise délicate. The device and method according to the invention provides the advantage of carrying out prefabrication in the factory and eliminating all the constraints of casting in place several meters in height, casting too often carried out in unfavorable climatic conditions, therefore delicate mastery.
Le dispositif comporte un ou plusieurs éléments longs préfabriqués formés chacun par une ou plusieurs poutrelles d'acier entières ou découpées enrobées de béton, le procédé d'assemblage et de fonctionnement consistant à lier transversalement et verticalement les éléments sur toute leur longueur pour constituer un ouvrage monolithique montable et démontable de par le couplage et découplage longitudinal de l'ouvrage possible par la decoupe longitudinale. The device comprises one or more prefabricated long elements each formed by one or more whole or cut steel beams coated with concrete, the assembly and operating process consisting in linking the elements transversely and vertically over their entire length to constitute a structure. monolithic mountable and dismountable by the coupling and longitudinal decoupling of the structure possible by the longitudinal cutting.
La solidarisation entre les éléments est réalisée sur différents profils en travers des éléments par le double contact et blocage - transversal d'une part, entre les faces longitudinales et latérales de chacun des éléments par précontrainte transversale. The joining between the elements is carried out on different profiles across the elements by the double contact and blocking - transverse on the one hand, between the longitudinal and lateral faces of each of the elements by transverse prestressing.
- vertical d'autre part entre des facettes d'appui spécialement aménagées sur chacun des éléments. Ces facettes pouvant être: * horizontales sur l'intrados et l'extrados par précontrainte verticale au moyen d'un goujon placé à l'interface des éléments dans des réservations.- vertical on the other hand between specially fitted support facets on each of the elements. These facets can be: * horizontal on the lower surface and upper surface by vertical prestressing by means of a stud placed at the interface of the elements in reservations.
* inclinées ménagées sur les faces longitudinales et latérales des éléments y compris leurs entretoises, de type tenon, mortaise ou empreinte destinée à coopérer avec une clé ou clavette. * inclined formed on the longitudinal and lateral faces of the elements including their spacers, of the tenon, mortise or indentation type intended to cooperate with a key or key.
Dans ces différents cas le transfert des contraintes d'un élément à l'autre passe par une pièce intermédiaire, goulon,tenon, clé, clavette. In these different cases, the transfer of stresses from one element to the other goes through an intermediate piece, goulon, tenon, key, key.

En référence à ces dessins, le dispositif comporte au moins deux éléments, un élément est constitué par une poutrelle (1) enrobée dans du béton (2) ménageant une réservation tubulaire (3) transversale et un assemblage (4) vertical par exemple par réservation d'empreintes femelles ou mâles sur au moins une face verticale latérale de l'élément longitudinal. With reference to these drawings, the device comprises at least two elements, one element consists of a beam (1) embedded in concrete (2) providing a tubular reservation (3) transverse and an assembly (4) vertical for example by reservation female or male imprints on at least one lateral vertical face of the longitudinal element.
Le procédé d'assemblage consiste par l'intermédiaire d'une barre filetée ou d'une barre ou câble de précontrainte (5) à exercer une précontrainte transversale entre au moins deux éléments par le dispositif de serrage et de blocage d'about (6) immobilisant latéralement et verticalement un élément par rapport à l'autre ou aux autres, rendant l'ensemble monolithe. The assembly process consists of using a threaded bar or a prestressing bar or cable (5) to exert a transverse prestress between at least two elements by the end clamping and locking device (6 ) laterally and vertically immobilizing an element with respect to the other or to the others, making the whole monolith.
Dans la forme de réalisation de la figure 2 chaque élément comporte deux profilés (1). In the embodiment of Figure 2 each element has two sections (1).
Dans la forme de réalisation de la figure 3 des élégissements sont pratiqués et l'assemblage (4) s'opère sur la tranche de la dalle de façon continue ou discontinue. In the embodiment of FIG. 3, elegance is practiced and the assembly (4) takes place on the edge of the slab continuously or discontinuously.
Dans la forme de réalisation de la figure 4 l'élément peut comporter des entretoises et les entretoises porter le dispositif d'assemblage, par exemple tenon mortaise, mais aussi il peut être femelle sur l'un et l'autre élément, une clé polydièdre (10) figure 5 prise en sandwich entre les entretoises (9) assure le clavetage des éléments par l'intermédiaire du dispositif de serrage et de blocage (6) mis en jeu par la précontrainte transversale, une réservation tubulaire pouvant être pratiquée dans la clé pour le passage de la barre ou du câble de précontrainte (5)
Dans la forme de réalisation de la figure 6 on perçoit bien le montage précité de la clé. II est à noter qu'avec une entretoise d'about les câbles peuvent se placer plus en dessous de la table de compression.In the embodiment of Figure 4 the element may include spacers and the spacers carry the assembly device, for example mortise tenon, but also it may be female on one and the other element, a polydièdre key (10) figure 5 sandwiched between the spacers (9) ensures the keying of the elements by means of the tightening and blocking device (6) brought into play by the transverse prestressing, a tubular reservation can be made in the key for the passage of the prestressing bar or cable (5)
In the embodiment of Figure 6 we clearly perceive the aforementioned mounting of the key. It should be noted that with an end spacer the cables can be placed further below the compression table.
Dans la forme de réalisation de la figure 7, I'assemblage vertical est assuré par une série de goujons (11) verticaux placés à l'interface des éléments dans une réservation aménagée. In the embodiment of FIG. 7, the vertical assembly is ensured by a series of vertical studs (11) placed at the interface of the elements in a fitted reservation.
Dans la forme de réalisation de la figure 8 des éléments éllégis de section U renversée sont solidarisés par une barre ou câble (5) de précontrainte sur la longueur réduite des poutres accolées. In the embodiment of Figure 8 of the elegant elements of inverted U section are secured by a bar or cable (5) prestressing on the reduced length of the adjoining beams.
Dans la forme de réalisation de la figure 9 il y a combinaison entre des éléments élégis U et T avec des poutrelles découpées et un clavetage vertical par goujons. In the embodiment of FIG. 9 there is a combination of elegant elements U and T with cut beams and a vertical keying by studs.
Le dispositif selon l'invention est particulièrement destiné à la réalisation des planchers, ponts et ouvrages d'art de génie civil. The device according to the invention is particularly intended for the production of floors, bridges and civil engineering structures.
