Abstract

The construction can be used on light concrete or ceramic sections which are compressible but offer high resistance mechanically. The metal rod (1) has a fixed stop (2) at one end and is threaded at the other end so that when it is passed through preformed holes in the sections, a screw (4) can tighten them together so that the whole assembly is in compression. The screw can be replaced by a ratchet lever and the construction is completed by filling the holes with a protective layer of synthetic resin.

Description

L'objet de l'invention concerne un dispositif d'assemblage provisoire ou définitif d'éléments préfabri- qués pour la construction. The object of the invention relates to a device for provisional or definitive assembly of prefabricated elements for construction.

Il est destiné à permettre la réalisation économi- que et homogène d'éléments porteurs et autoporteurs à destinations multiples, tels que planchers porteurs ou non, faux plafonds, murs, revêtements muraux et coffrages
Dans les dispositifs connus les éléments simples utilisés danq la construction en céramique ou ciment étaient assemblés sur chantier ou en usine pour constituer des chaînages, poutres, et autres.It is intended to allow economical and uniform production of load-bearing and self-supporting elements for multiple destinations, such as load-bearing or non-load-bearing floors, false ceilings, walls, wall coverings and formwork
In known devices, the simple elements used in the ceramic or cement construction were assembled on site or in the factory to form chaining, beams, and the like.

Ils étaient stockés et transportés par unité, ce qui demandait une main-d'oeuvre importante et augmentait les risques de déterioration.  They were stored and transported per unit, which required significant labor and increased the risk of deterioration.

Le dispositif suivant l'invention supprime ces inconvénients et permet d'utiliser les unités d'éléments par juxtaposition ou superposition en nombre variable, en les tendant et les mettant en compression, afin de les rendre homogènes et monolithiques, mais prêts à leur utilisation comme éléments porteurs ou autoporteurs. The device according to the invention eliminates these drawbacks and makes it possible to use the units of elements by juxtaposition or superposition in variable number, by stretching them and putting them in compression, in order to make them homogeneous and monolithic, but ready for their use as load-bearing or self-supporting elements.

Il est constitué par la combinaison d'éléments compressibles de forte résistance mécanique compacte en béton lourd ou léger ou céramique et d'éléments étirables mStal- liques avec système de mise en tension et de blocage int4- gré. It is made up of a combination of compressible elements with high compact mechanical strength in heavy or light concrete or ceramic and metallic stretch elements with integrated tensioning and blocking system.

Sur les dessins annexés, donnés à titre d'exemple non limitatif, d'une des formes de réalisation de l'objet de l'invention s
ha figure 1 représente vu en élévation l'élément étirable mécanique avec son dispositif de tension et d'arrOt.In the accompanying drawings, given by way of nonlimiting example, of one of the embodiments of the subject of the invention s
ha Figure 1 shows in elevation the mechanical stretchable element with its tensioning and stopping device.

Les figures 2 et 3 montrent des variantes d'exécu- tion de l'élément tendeur. Figures 2 and 3 show alternative embodiments of the tensioning element.

Les figures 4, 5, 6, 7, 8 représentent certaines des applications du dispositif.  Figures 4, 5, 6, 7, 8 show some of the applications of the device.

L'élément tendeur élastique est constitué par
une tige métallique 1, fig 1, 2, 3, comportant à une extré- mité une plaque formant butée d'arr & fixe 2.The elastic tensioning element is constituted by
a metal rod 1, fig 1, 2, 3, comprising at one end a plate forming a fixed stop 2.

Son extrémité opposée est filetée 3, et reçoit un écrou de tension 4, avec ou sans contre-plaque de pression 5. Its opposite end is threaded 3, and receives a tension nut 4, with or without pressure counter plate 5.

On peut utiliser un levier d'encliquetage tendeur 6, ou un double écrou 7, avec contre-plaque 8, qu'on bloque à la place de la plaque fixe 2.ou clavette conique. One can use a tensioning snap lever 6, or a double nut 7, with counter plate 8, which is blocked in place of the fixed plate 2. or conical key.

Ces tiges sont passées dans les orifices 9-, 10 des séries deléments 11, 12, 13 juxtaposées. These rods are passed through the holes 9-, 10 of the series of elements 11, 12, 13 juxtaposed.

Ce dispositif est utilisable pour l'assemblage de de tous les types dtélements généralement utilisés en construction 14, 15 dans les plans horizontaux ou verticaux pourvus de perforations 16, 17. This device can be used for the assembly of all types of elements generally used in construction 14, 15 in the horizontal or vertical planes provided with perforations 16, 17.

Les piliers 18, 19, ou les canaux, et les éléments de tous profils, ainsi que pour toutes les applications sont assemblables par paires et en nombre variable suivant leurs applications. The pillars 18, 19, or the channels, and the elements of all profiles, as well as for all the applications, can be assembled in pairs and in variable number according to their applications.

L'ensemble peut 8trie associé à des éléments de remplissage et peut constituer un tout, à destination multiples. The assembly can be combined with filling elements and can constitute a whole, for multiple purposes.

La stabilité et la pérennité de 1 1ouvrage est obtenue par l'injection dans les orifices 9. 10 et autres de liants hydrauliques ou de résines synthétiques. The stability and durability of the structure is obtained by the injection into the orifices 9, 10 and the like of hydraulic binders or synthetic resins.

L'assemblage ainsi constitué peut entre complété par le coulage de béton hydraulique avec ou sans armature. The assembly thus formed can be completed by pouring hydraulic concrete with or without reinforcement.

Cet assemblage peut être provisoire ou définitif et opérer avec les moyens de fabrication simplifiée et économiques ne nécessitant aucun outillage spécial.  This assembly can be temporary or final and operate with simplified and economical manufacturing means requiring no special tools.

C'est ainsi, qu'on peut à tout moment réduire, augmenter ou séparer les éléments suivant les besoins du moment. Thus, we can at any time reduce, increase or separate the elements according to the needs of the moment.

Il est non seulement possible de réaliser à sec des coffrages de longueurs classiques, mais encore de doubler ou tripler la longueur des éléments par cette "précontrainte" et de réaliser ainsi, des blocs autonomes autoporteurs et autordsistantss. It is not only possible to dry formwork of conventional lengths, but also to double or triple the length of the elements by this "preload" and thus achieve self-supporting, self-supporting and self-supporting blocks.

Toutefois les formes, dimensions et dispositions des différents éléments pourront varier dans la limite des équivalents, comme d'ailleurs les moyens utilisés pour leur fabrication sans changer pour cela la conception gé- neurale de l'invention qui vient d'8tre décrite0  However, the shapes, dimensions and arrangements of the various elements may vary within the limit of the equivalents, like the means used for their manufacture without thereby changing the general conception of the invention which has just been described.
