Description

       

  "Eléments composites pour la construction de joints de

  
retrait ou de dilatation" L'invention concerne des éléments composites pour la construction de joints de retrait ou de dilatation. Plus spécialement, l'invention a pour objets des éléments pour la réalisation de joints de retrait ou de dilatation sans tassement différentiel pour tous ouvrages de géniecivil, tels que routes, pistes d'aviation, aires de circulation, de parkings ou de stockages, entrepôts frigorifiques, dalles ou chapes flottantes, pertuis, tunnels, bâtiments et similaires.

  
Un premier objet de l'invention consiste à relier entre eux, par une liaison rigide, au moins deux éléments de transfert de charge, du type plaque mince connu en soi, de façon à éviter le déplacement relatif de ces éléments isolés légers.

  
Un autre objet de l'invention est que ces éléments composites, étant plus lourds que les éléments isolés, ont

  
une meilleure stabilité lors de leur mise en oeuvre.

  
Un autre objet de l'invention consiste en ce que ces éléments composites facilitent considérablement la manutention et la rapidité de pose par rapport aux éléments isolés connus.

  
Un autre objet de l'invention est que les éléments de transfert de charge de l'élément composite sont disposés de telle façon qu'ils augmentent la longueur de la zone où doit s'effectuer le sciage; on obtient donc la certitude d'un sciage correct.

  
Un autre objet de l'invention consiste à relier des éléments composites entre eux au moyen d'un dispositif permettant une solidarisation et un alignement aisés de ces éléments.

  
Un autre objet de l'invention consiste en ce que les dispositifs parallèles à l'axe des joints servent également

  
de supports pour les armatures de la dalle.

  
Un autre objet de l'invention consiste à utiliser des éléments de transfert de charge et leurs dispositifs de liaison parallèles à l'axe des joints d'une hauteur telle que l'ensemble se trouve toujours sous la nappe d'armatures de la dalle et permettent, ainsi, l'utilisation de tous les susdits types d'armatures quelle que soit la dimension de leurs mailles.

  
Les éléments selon l'invention permettant d'obtenir les susdits avantages sont essentiellement constitués par au moins deux plaques minces quadrangulaires dont la moitié

  
de la surface supérieure présente des éléments d'ancrage ou barres d'attente, ces plaques étant placées et mutuellement solidarisées l'une derrière l'autre,les barres d'attente

  
étant disposées en quinconce.

  
Afin de mieux faire ressortir les caractéristiques

  
de la présente invention, une forme d'exécution préférée est décrite ci-apr ès, à titre d'exemple, sans caractère limitatif, en se référant aux dessins annexés dans lesquels :
la figure 1 représente en vue perspective un élément composite selon l'invention; la figure 2 représente, en vue en plan et schématiquement, une aire de roulement à l'endroit d'un joint de retrait ou de dilatation,exécutée selon l'invention; la figure 3 représente une coupe à échelle agrandie, selon la ligne III-III de la figure 2; la figure 4 est un agrandissement de la partie indiquée en F4 à la figure 2.

  
Dans la figure 1 est illustré un élément composite

  
 <EMI ID=1.1> 

  
soi. Chaque élément isolé est constitué par une assise 3 et des moyens d'accrochage ou barres d'attente 4 en forme d'étrier. Ces barres d'attente 4 sont situées sur la face supérieure de l'assise 3 et, ce, d'une manière telle qu'elles se présentent uniquement sur la moitié de la surface supérieure de l'assise.

  
Dans l'exemple de la figure 1, quatre éléments 2 sont placés l'un derrière l'autre afin de former un alignement, les étriers 4 étant disposés en quinconce et les plaques 2 étant mutuellement solidarisées à la partie supérieure de leurs barres d'attente 4 par un élément de liaison constitué par

  
 <EMI ID=2.1> 

  
rence, fixées à une certaine distance de l'extrémité des longerons 5 et 6 de manière à former des tiges de guidage, respectivement 10-11-12 et 13.

  
Ces éléments composites seront mis en alignement en dessous de la dalle 14, des éléments composites 1 étant de préférence fixés l'un à l'autre au moyen de manchons 15 dans lesquels sont engagées les tiges de guidage co-axiales 10-11-12

  
et 13 des éléments composites voisins.

  
La résistance des traverses 7-8-9 doit être telle que ces dernières puissent se déformer ou se rompre lors des mouvements de retrait et de dilatation de la dalle, sans perturber le fonctionnement du joint.

  
 <EMI ID=3.1> 

  
riau adéquat. Toutefois, ces éléments seront'de préférence, exécutés en acier.

  
Dans une exécution préférentielle, les longerons 5 et 6 ainsi que les traverses 7-8-9 sont fixés entre eux et sur les barres d'attente 4 des éléments 2 par soudage.

  
Il va de soi que l'invention n'est nullement limitée à l'exécution décrite ci-dessus et représentée aux dessins annexés. Toutes variantes peuvent y être apportées sans, pour autant, sortir du cadre de l'invention.

  "Composite elements for the construction of

  
shrinkage or expansion "The invention relates to composite elements for the construction of contraction or expansion joints. More specifically, the invention relates to elements for the production of contraction or expansion joints without differential settlement for all structures civil engineering, such as roads, runways, traffic areas, parking lots or storage areas, cold stores, slabs or floating screeds, sluices, tunnels, buildings and the like.

  
A first object of the invention consists in connecting together, by a rigid connection, at least two load transfer elements, of the thin plate type known per se, so as to avoid the relative displacement of these light isolated elements.

  
Another object of the invention is that these composite elements, being heavier than the isolated elements, have

  
better stability during their implementation.

  
Another object of the invention consists in that these composite elements considerably facilitate the handling and the speed of installation compared to known isolated elements.

  
Another object of the invention is that the load transfer elements of the composite element are arranged in such a way that they increase the length of the zone where the sawing is to be carried out; one thus obtains the certainty of a correct sawing.

  
Another object of the invention consists in connecting composite elements to one another by means of a device allowing easy joining and alignment of these elements.

  
Another object of the invention is that the devices parallel to the axis of the joints also serve

  
supports for the slab reinforcements.

  
Another object of the invention is to use load transfer elements and their connecting devices parallel to the axis of the joints of a height such that the assembly is always located under the layer of reinforcements of the slab and allow, thus, the use of all the aforesaid types of reinforcements whatever the dimension of their meshes.

  
The elements according to the invention making it possible to obtain the aforesaid advantages are essentially constituted by at least two quadrangular thin plates, half of which

  
of the upper surface has anchoring elements or waiting bars, these plates being placed and mutually secured one behind the other, the waiting bars

  
being arranged in staggered rows.

  
In order to better highlight the characteristics

  
of the present invention, a preferred embodiment is described below, by way of example, without limitation, with reference to the accompanying drawings in which:
FIG. 1 represents in perspective view a composite element according to the invention; FIG. 2 shows, in plan view and schematically, a running surface at the location of a shrinkage or expansion joint, made according to the invention; FIG. 3 represents a section on an enlarged scale, along the line III-III of FIG. 2; Figure 4 is an enlargement of the part indicated at F4 in Figure 2.

  
In figure 1 is illustrated a composite element

  
 <EMI ID = 1.1>

  
self. Each isolated element consists of a seat 3 and hooking means or waiting bars 4 in the form of a stirrup. These waiting bars 4 are located on the upper face of the seat 3 and, this, in such a way that they are present only on half of the upper surface of the seat.

  
In the example of Figure 1, four elements 2 are placed one behind the other to form an alignment, the brackets 4 being staggered and the plates 2 being mutually secured to the upper part of their bars. hold 4 by a connecting element consisting of

  
 <EMI ID = 2.1>

  
rence, fixed at a certain distance from the end of the side members 5 and 6 so as to form guide rods, respectively 10-11-12 and 13.

  
These composite elements will be placed in alignment below the slab 14, the composite elements 1 preferably being fixed to each other by means of sleeves 15 in which the co-axial guide rods 10-11-12 are engaged.

  
and 13 neighboring composite elements.

  
The strength of cross members 7-8-9 must be such that they can deform or break during the retraction and expansion movements of the slab, without disturbing the operation of the joint.

  
 <EMI ID = 3.1>

  
adequate sound. However, these elements will preferably be made of steel.

  
In a preferred embodiment, the side members 5 and 6 as well as the cross members 7-8-9 are fixed to each other and to the waiting bars 4 of the elements 2 by welding.

  
It goes without saying that the invention is in no way limited to the embodiment described above and shown in the accompanying drawings. All variants can be made thereto without, however, departing from the scope of the invention.
