Abstract

The base (1) of the clamp has a central section which is toothed or serrated (7). Each vertical leg (2, 3) has similar sections (8, 9) respectively. The two legs are closed by a tie bolt (4) and nuts (5, 6). The serrated sections grip the tube (10) in three places thus preventing movement in a linear and angular direction. ADVANTAGE - Clamp is positive and can accommodate clearance without the use of separate keys.

Description

L'objet de l'invention concerne un perfectionnement apporté aux étriers d'assemblage et de fixation des éléments tubulaires de structuration pour serres tunnels. The object of the invention relates to an improvement made to the stirrups for assembling and fixing tubular structuring elements for tunnel greenhouses.

Il a pour but de permettre la fixation stabilisée avec rattrapage de jeu des structures auto-portantes. Its purpose is to allow stabilized fixing with backlash of self-supporting structures.

Jusqu'à ce jour les étriers soudés sur les entretoises étaient clavetés avec l'aide de cales de de butées empêchant leur déplacement aussi bien rotatif que translatif, les assemblages étaient coûteux, complexes et il suffisait de quelques millimètres de différence de diamètre pour déstabiliser les structures. Until now the stirrups welded on the spacers were keyed with the help of shims of stops preventing their displacement as well rotary as translative, the assemblies were expensive, complex and it was enough a few millimeters of difference in diameter to destabilize the structures.

Le dispositif suivant l'invention supprime ces inconvénients, permet de rattraper les différences de diamètres des éléments tubulaires et de les immobiliser sur tous points empêchant omnidirectionnellement tous les maniements. The device according to the invention eliminates these drawbacks, makes it possible to make up for the differences in diameters of the tubular elements and to immobilize them on all points preventing omnidirectionally all handling.

Il est constitué par le crantage d'au moins trois parois de l'étrier avec ou sans méplat du tube au point d'immobilisation. It consists of the notching of at least three walls of the stirrup with or without the flat part of the tube at the point of immobilization.

Sur les dessins annexés, donnés à titre d'exemple non limitatif, d'une des formes de réalisation de l ' objet de l'invention
La figure 1 représente vu en élévation l'étrier avec ses profils d'ancrage.In the accompanying drawings, given by way of nonlimiting example, of one of the embodiments of the subject of the invention
Figure 1 shows in elevation the stirrup with its anchoring profiles.

La figure 2 montre une variante d'exécution du même dispositif. Figure 2 shows an alternative embodiment of the same device.

Les figures 3, t, 5 représentent les mêmes applications -du dispositif pour la structuration des serres. tunnels. Figures 3, t, 5 show the same applications of the device for structuring greenhouses. tunnels.

L'étrier, figures 1, 2, 3, 4, est constitué par une surface portante ou fond 1 et deux branches de serrage 2, 3 formant mâchoires rapprochées par le boulon 4 avec écrous de serrage 5, 6. The stirrup, FIGS. 1, 2, 3, 4, is constituted by a bearing surface or bottom 1 and two clamping branches 2, 3 forming jaws brought together by the bolt 4 with clamping nuts 5, 6.

Le fond ou traverse 1 de l'étrier comporte un profil d'ancrage 7 formé par un crantage avec pointes. The bottom or cross member 1 of the stirrup has an anchoring profile 7 formed by a notching with spikes.

Les branches 2, 3 comportent symétriquement opposées des profils crantés identiques 8, 9 de sorte que l'élément tubulaire 10 est immobilisé sur trois points d'ancrage par contact de plusieurs dentures supprimant toute possibilité de rotation ou de translation.  The branches 2, 3 have symmetrically opposite identical notched profiles 8, 9 so that the tubular element 10 is immobilized on three anchoring points by contact with several teeth eliminating any possibility of rotation or translation.

Le serrage des branches 2, 3 par le boulon L rappro- che les machoires et crante les pointes dans la périphérie du tube 10 avec triple points de contacts immobilisateurs omnidirectionnels suivant une variante d'exécution, fig 2, l'élément tubulaire 11 est ovale est comporte des méplats 12, 13. The tightening of the branches 2, 3 by the bolt L brings the jaws together and notches the points in the periphery of the tube 10 with triple omnidirectional immobilizing contact points according to an alternative embodiment, fig 2, the tubular element 11 is oval is has flats 12, 13.

Des crantages latéraux 14, 14', 15, 15', suffisent pour ancrer l'élément tubulaire sur les points de contacts séparés. Lateral notches 14, 14 ′, 15, 15 ′ are sufficient to anchor the tubular element on the separate contact points.

Le boulon avec écrous 16, 17, 18 rapproche les mâchoires.The bolt with nuts 16, 17, 18 brings the jaws together.

L'étrier 19, fig 3, peut être fixé sur un tube 20 à sa partie supérieure 21. On peut également inverser le sens de fixation de l'étrier 22, fig 4, s'immobilisant sur les faces latérales 23 avec ancrage à la partie inférieure 24. The stirrup 19, fig 3, can be fixed on a tube 20 at its upper part 21. It is also possible to reverse the direction of fixing of the stirrup 22, fig 4, immobilizing on the lateral faces 23 with anchoring to the lower part 24.

Les structures longitudinales 25, 26, 27 sont assemblées sur les arceaux 28, 29 et autres. The longitudinal structures 25, 26, 27 are assembled on the arches 28, 29 and the like.

Les assemblages sont rapides, auto-stabilisants et suppriment tout jeu et toutes vibrations quelles que soient les sollicitations reçues ou transmises. The assemblies are fast, self-stabilizing and eliminate all play and all vibrations whatever the stresses received or transmitted.

Le dispositif d'assemblage par étriers permet de réaliser des points d 'ancrages fermés et stables et donne la possibilité d'appliquer à la structure des serres chapelles et tunnels, le principe de la poutre échelle continue. The assembly device by stirrups allows to realize closed and stable anchor points and gives the possibility of applying to the structure of greenhouses chapels and tunnels, the principle of the continuous scale beam.

La structuration des serres tunnels plus particulière
ment est améliorée dans des proportions importantes et les prix de revient des montages considérablement abaissés.The more specific structure of tunnel greenhouses
ment is improved in significant proportions and the cost of assemblies considerably lowered.

De plus le rattrapage des différents diamètres d'éléments tubulaires est obtenu en tout état de cause quelle que soit l'importance des irrégularités. In addition, the take-up of the different diameters of tubular elements is obtained in any event regardless of the size of the irregularities.

Car à l'effet combiné des crantages et du boulon s'ajoute la légère flexibilité des branches qui cerclent la monture. Because to the combined effect of the notches and the bolt is added the slight flexibility of the branches that encircle the frame.

Les formes, dimensions et dispositions des différents éléments comme d ' ailleurs les matières utilisées pour leur fabrication pourront varier dans la limite des équivalents,sans changer pour cela, la conception générale de l'invention qui vient d'être décrite.  The shapes, dimensions and arrangements of the various elements as well as the materials used for their manufacture may vary within the limit of equivalents, without changing the general conception of the invention which has just been described.
