Definitions

  • the present invention relates to a device for suspending a tube horizontal heat exchange on a vertical support tube a flat profile being welded to the vertical support tube externally to its wall and parallel to its axis, said flat profile comprising a rounded notch for receiving a support piece for receiving said horizontal tube.
  • Patent FR 2 741 706 describes such a device.
  • Such a device uses a molded bearing part of complex shape may crack.
  • the present invention aims to provide a suspension device simpler using no complicated molded parts.
  • the subject of the invention is therefore a device for suspending a tube horizontal heat exchange on a vertical support tube, a flat profile being welded to the vertical support tube outside its wall and parallel to its axis, said flat profile comprising a rounded notch for receiving a part support for receiving said horizontal tube, characterized in that said piece receiving support is a folded sheet marrying said notch and enveloping a part of the outer periphery of the tube, the upper and lower ends of which are each folded towards said flat profile to be welded therein, and in that a collar closing on the horizontal tube is fixed against said support piece reception.
  • said ends folded towards the flat profile carry each cut so that these ends embrace the flat profile and be welded to it.
  • Figure 1 shows in elevation a device according to the invention for the suspension of a horizontal heat exchange tube on a vertical support tube.
  • Figure 2 is a section on II-II of Figure 1.
  • Tube 1 is part of a vertical sheet of horizontal tubes such as 1 heat exchanger suspended from a few vertical support tubes such as 2 connected to a fixed structure not shown. A second layer of tubes 1A horizontal is also supported by the carrier tubes 2 facing the tubes 1. Only the suspension device for a single tube, tube 1, is shown in the drawing.
  • the suspension device comprises a welded flat profile 3 outside the tube 2 parallel to its axis 4.
  • This profile 3 is used for the suspension of the whole ply of tubes such as 1 (for tubes 1A, a profile 3A is also welded on the other side of the vertical tube 2).
  • the profile 3 includes a rounded notch 5 for receive a receiving support piece which consists of a simple folded sheet 6 which marries by its external face the rounded notch 5 and which envelops internally part of the outer periphery of the tube 1.
  • the ends 7 and 8 of the sheet 6 are folded towards the flat profile 3 and each carry a cutout 9 of so as to embrace the flat profile 3 to which each end is welded at 10.
  • a collar 11 also consisting of a simple folded sheet comes close on the tube 1 and its ends 12 and 13 are welded to the folded sheet 6.
  • a metal round 14 fills, when welding, the clearance between the ends of the collar 11 and the folded sheet 6.
  • the shrinkage after welding wedges the tube 1 between the two half-shells formed by parts 6 and 11.
  • the tube 1 is thus firmly held.
  • the suspension device according to the invention is very simple and economical since it only includes laminated and notched parts.

Description

La présente invention concerne un dispositif pour la suspension d'un tube horizontal d'échange de chaleur sur un tube porteur vertical un profilé plat étant soudé au tube porteur vertical extérieurement à sa paroi et parallèlement à son axe, ledit profilé plat comportant une encoche arrondie de réception d'une pièce support de réception dudit tube horizontal.
Le brevet FR 2 741 706 décrit un tel dispositif.
Un tel dispositif utilise une pièce porteuse moulée de forme complexe pouvant se fissurer.
La présente invention a pour but de proposer un dispositif de suspension plus simple n'utilisant aucune pièce compliquée moulée.
L'invention a ainsi pour objet un dispositif pour la suspension d'un tube horizontal d'échange de chaleur sur un tube porteur vertical, un profilé plat étant soudé au tube porteur vertical extérieurement à sa paroi et parallèlement à son axe, ledit profilé plat comportant une encoche arrondie de réception d'une pièce support de réception dudit tube horizontal, caractérisé en ce que ladite pièce support de réception est une tôle pliée épousant ladite encoche et enveloppant une partie du pourtour externe du tube, et dont les extrémités supérieure et inférieure sont, chacune, repliées vers ledit profilé plat pour y être soudées, et en ce qu'un collier venant se refermer sur le tube horizontal est fixé contre ladite pièce support de réception.
Avantageusement, lesdites extrémités repliées vers le profilé plat portent chacune une découpe de façon à ce que ces extrémités embrassent le profilé plat et y soient soudées.
On va maintenant donner la description d'un exemple de mise en oeuvre de l'invention, en se référant au dessin annexé dans lequel :
La figure 1 montre en élévation un dispositif selon l'invention pour la suspension d'un tube horizontal d'échange de chaleur sur un tube porteur vertical.
La figure 2 est une coupe selon II-II de la figure 1.
En se référant aux figures, on voit ainsi représenté, un dispositif selon l'invention pour la suspension d'un tube horizontal 1 d'échangeur de chaleur sur un tube porteur vertical 2.
Le tube 1 fait partie d'une nappe verticale de tubes horizontaux tels que 1 d'échangeur de chaleur suspendus à quelques tubes porteurs verticaux tels que 2 reliés à une structure fixe non représentée. Une deuxième nappe de tubes 1A horizontaux est également supportée par les tubes porteurs 2 face aux tubes 1. Seul le dispositif de suspension d'un seul tube, le tube 1, est représenté sur le dessin.
Le dispositif de suspension comprend un profilé plat 3 soudé extérieurement au tube 2 parallèlement à son axe 4. Ce profilé 3 est utilisé pour la suspension de toute la nappe de tubes tels que 1 (pour les tubes 1A, un profilé 3A est également soudé de l'autre côté du tube vertical 2).
Au droit du tube 1, le profilé 3 comprend une encoche arrondie 5 pour recevoir une pièce support de réception qui est constituée d'une simple tôle pliée 6 qui épouse par sa face externe l'encoche arrondie 5 et qui envelopppe intérieurement une partie du pourtour externe du tube 1. Les extrémités 7 et 8 de la tôle 6 sont repliées vers le profilé plat 3 et portent, chacune, une découpe 9 de façon à embrasser le profilé plat 3 auquel chaque extrémité est soudée en 10.
Enfin, un collier 11 constitué également d'une simple tôle pliée vient se refermer sur le tube 1 et ses extrémités 12 et 13 sont soudées à la tôle pliée 6. Un rond métallique 14 comble, lors de la soudure, le jeu entre les extrémités du collier 11 et la tôle pliée 6.
Le retrait après soudage coince le tube 1 entre les deux demi-coquilles formées par les pièces 6 et 11. Le tube 1 est ainsi fermement maintenu.
Ainsi, le dispositif de suspension selon l'invention est très simple et économique puisqu'il ne comprend que des pièces laminées et encochées.
