Abstract

The installation of a steam boiler involves using a carrying structure (1) in the form of a tower of a determined height (H). A ceiling (2), of a height (h) less than that of the tower, is fixed to the top of the tower and boiler parts (3) are suspended from it. The procedure involves assembling the ceiling on the ground on which the tower is erected. The ceiling is then raised progressively to a determined height (hn) and the boiler parts suspended some metres from the ground. That height is less than or equal to the height of the boiler parts and is attained in stages. If it is less than the height of the boiler parts, the structure is erected to a determined height (h(n+1)). The ceiling is raised to this height and the boiler parts successively suspended. These stages are repeated until it reaches a height equal to that of the ceiling.

Description

La présente invention se rapporte à un procédé de montage d'une chaudière de production de vapeur.The present invention relates to a method of mounting a steam generating boiler.

Elle concerne plus précisément un procédé de montage d'une chaudière de production de vapeur constituée d'une structure porteuse en forme de tour de hauteur totale H, d'un plafond fixé au sommet de cette structure et de parties de chaudière suspendues à ce plafond de hauteur totale h, selon lequel

  • (a) on assemble ledit plafond porteur sur le sol cependant qu'on érige ladite structure porteuse à une hauteur hn,
  • (b) on lève progressivement le plafond jusqu'à la hauteur hn et monte successivement des parties de chaudière suspendues dans une position à quelques mètres du sol.
It relates more precisely to a method of mounting a steam generating boiler consisting of a support structure in the form of a tower of total height H, a ceiling fixed at the top of this structure and parts of the boiler suspended from this ceiling. total height h, according to which
  • (a) assembling said load-bearing ceiling on the ground, however, erecting said load-bearing structure at a height h n ,
  • (b) the ceiling is gradually raised to the height h n and successively raises parts of the boiler suspended in a position a few meters from the ground.

Un tel procédé de montage est décrit dans le brevet FR-2 648 216. Selon ce procédé connu, la hauteur hn est égale à la hauteur totale H de la chaudière, c'est-à-dire que pendant l'assemblage du plafond au sol, on érige toute la structure porteuse, le plafond est ensuite désassemblé en deux parties dont la partie centrale est levée progressivement jusqu'à la hauteur totale, les parties de chaudière étant suspendues à cette partie successivement dans une position à quelques mètres du sol.Such a mounting method is described in patent FR-2,648,216. According to this known method, the height h n is equal to the total height H of the boiler, that is to say that during the assembly of the ceiling. on the ground, the entire supporting structure is erected, the ceiling is then disassembled into two parts, the central part of which is gradually raised to full height, the parts of the boiler being suspended from this part successively in a position a few meters from the ground .

Selon ce procédé, le montage de toute la structure porteuse prend un délai important, avant lequel il est impossible de lever le plafond et de suspendre des parties de chaudière.According to this process, the assembly of the entire supporting structure takes a long time, before which it is impossible to raise the ceiling and suspend parts of the boiler.

L'invention propose un procédé de montage plus rapide.The invention provides a faster mounting method.

Pour ce faire, selon le procédé conforme à l'invention, ladite hauteur hn est inférieure à la hauteur totale H de la structure porteuse et on réalise pas à pas des étapes de levage du plafond et de montage des parties de chaudière simultanément à des étapes d'érection de la structure porteuse jusqu'à sa hauteur totale H.To do this, according to the method according to the invention, said height h n is less than the total height H of the support structure and steps for lifting the ceiling and mounting the boiler parts are performed step by step simultaneously with stages of erection of the supporting structure up to its total height H.

De préférence, ladite hauteur hn est inférieure ou égale à la hauteur des parties de chaudière h et le procédé comporte également les étapes suivantes:

  • (c) si hn est inférieure à h, on érige la structure porteuse à au moins une hauteur hn+1, simultanément à l'étape précédente,
  • (d) on lève progressivement le plafond jusqu'à la hauteur hn+1 et monte successivement des parties de chaudière suspendues dans une position à quelques mètres du sol,
  • on répète les étapes (c) et (d) jusqu'à ce que hi soit sensiblement égale à h,
  • on érige la structure porteuse à sa hauteur totale H, simultanément à l'étape précédente,
  • on lève ensuite le plafond jusqu'à la hauteur H.
Preferably, said height h n is less than or equal to the height of the boiler parts h and the method also includes the following steps:
  • (c) if h n is less than h, the supporting structure is erected at least at a height h n + 1 , simultaneously with the preceding step,
  • (d) the ceiling is gradually raised to the height h n + 1 and successively parts of the boiler suspended in a position a few meters from the ground,
  • steps (c) and (d) are repeated until h i is substantially equal to h,
  • the supporting structure is erected at its total height H, simultaneously with the previous step,
  • the ceiling is then raised to height H.

Dans le cas d'une chaudière de production de vapeur comportant une structure porteuse constitué de pylônes reliés par des poutres horizontales et de contreventements, le plafond peut être provisoirement posé aux hauteurs hi sur des poutres de pose provisoires supportées par des poutres maîtresses horizontales de la structure porteuse.In the case of a steam generating boiler comprising a support structure consisting of pylons connected by horizontal beams and bracing, the ceiling can be temporarily placed at heights h i on temporary laying beams supported by horizontal master beams of the supporting structure.

Dans le cas d'une chaudière de production de vapeur comportant une structure porteuse constitué de pylônes reliés par des contreventements, le plafond peut être provisoirement posé aux hauteurs hi sur des plots de pose supportés par les pylônes de la structure porteuse.In the case of a steam generating boiler comprising a support structure consisting of pylons connected by braces, the ceiling can be temporarily placed at heights h i on mounting pads supported by the pylons of the support structure.

Le levage du plafond peut être réalisé par des vérins hydrauliques fixés sur des poutres de support provisoires supportées par des poutres maîtresses horizontales de la structure porteuse ou sur des rehausses provisoires supportées aux hauteurs hi par des poutres horizontales de la structure porteuse.The lifting of the ceiling can be carried out by hydraulic jacks fixed on temporary support beams supported by horizontal main beams of the support structure or on temporary extensions supported at heights h i by horizontal beams of the support structure.

L'invention est décrite ci-après plus en détail à l'aide de figures ne représentant qu'un mode de réalisation préféré de l'invention.The invention is described below in more detail using figures showing only a preferred embodiment of the invention.

Les figures 1 à 5 représentent en perspective les différentes étapes du montage d'une chaudière selon le procédé conforme à l'invention.Figures 1 to 5 show in perspective the different stages of mounting a boiler according to the method according to the invention.

La figure 6 est une vue partielle en perspective d'une variante de réalisation.Figure 6 is a partial perspective view of an alternative embodiment.

Une chaudière de production de vapeur est constituée d'une structure porteuse 1 en forme de tour de hauteur totale H , d'un plafond 2 fixé au sommet de cette structure et de parties de chaudière 3 suspendues à ce plafond 2 et de hauteur totale h. La structure porteuse 1 est constitué de pylônes 1A reliés par des poutres horizontales 1B et de contreventements 1C. Une telle chaudière, une fois montée, est représentée sur la figure 6.A steam generating boiler consists of a support structure 1 in the form of a tower of total height H, a ceiling 2 fixed at the top of this structure and boiler parts 3 suspended from this ceiling 2 and of total height h . The supporting structure 1 consists of pylons 1A connected by horizontal beams 1B and braces 1C. Such a boiler, once mounted, is shown in Figure 6.

Le procédé conforme à l'invention commence par les étapes suivantes, après préparation des massifs supports des pylônes 1A de la structure porteuse 1 et du sol à un niveau 0:

  • (a) on assemble le plafond 2 sur le sol dans un gabarit légèrement inférieur au gabarit intérieur de la structure porteuse 1, cependant qu'on érige ladite structure porteuse 1 au moins à une hauteur h1, comme représenté sur la figure 1, au moyen d'une grue 7;
  • (b) on installe sur la structure porteuse 1 des vérins hydrauliques 5, comme représenté sur la figure 2; ils sont fixés sur des poutres de support provisoires 6 supportées par les poutres horizontales 1B de la structure porteuse 1, au-dessus de la hauteur h1; grâce aux vérins 5, on lève progressivement le plafond 2 jusqu'à la hauteur h1 et monte successivement, tranche par tranche, des parties de chaudière 3A suspendues dans une position à quelques mètres du sol, comme représenté sur la figure 3; une fois la hauteur h1 atteinte, le plafond 2 est stabilisé comme représenté sur la figure 4; pour ce faire, il est provisoirement posé sur des poutres de pose 4 provisoires supportées par les poutres maîtresses horizontales 1B de la structure porteuse 1.
The process in accordance with the invention begins with the following steps, after preparation of the solid supports for the pylons 1A of the supporting structure 1 and of the ground at a level 0:
  • (a) the ceiling 2 is assembled on the ground in a template slightly lower than the inside template of the support structure 1, however that said support structure 1 is erected at least at a height h 1 , as shown in FIG. 1, at by means of a crane 7;
  • (b) hydraulic cylinders 5 are installed on the support structure 1, as shown in FIG. 2; they are fixed on temporary support beams 6 supported by the horizontal beams 1B of the supporting structure 1, above the height h 1 ; thanks to the jacks 5, the ceiling 2 is gradually raised to the height h 1 and successively rises, section by section, parts of the boiler 3A suspended in a position a few meters from the ground, as shown in FIG. 3; once the height h 1 has been reached, the ceiling 2 is stabilized as shown in FIG. 4; to do this, it is temporarily placed on 4 temporary laying beams supported by the horizontal master beams 1B of the supporting structure 1.

On érige la structure porteuse 1 à sa hauteur totale H, simultanément à l'étape précédente, comme représenté sur les figures 3 et 4 et on lève ensuite le plafond 2 jusqu'à la hauteur H, grâce aux vérins 5 installés au sommet de la structure porteuse 1, comme représenté sur les figures 4 et 5. Eventuellement des parties de chaudière 3 peuvent encore être montées à quelques mètres du sol, lors de cette dernière opération de levage du plafond 2.The supporting structure 1 is erected at its total height H, simultaneously with the previous step, as shown in FIGS. 3 and 4 and the ceiling 2 is then raised to the height H, thanks to the jacks 5 installed at the top of the supporting structure 1, as shown in FIGS. 4 and 5. Optionally, parts of the boiler 3 can still be mounted a few meters from the ground, during this last operation for lifting the ceiling 2.

Au sommet de la structure porteuse 1, les vérins 5 sont fixés sur des rehausses 8 en forme de portique pour permettre le levage du plafond 2 jusqu'au niveau des dernières poutres horizontales 1B.At the top of the supporting structure 1, the jacks 5 are fixed on risers 8 in the form of a gantry to allow the lifting of the ceiling 2 to the level of the last horizontal beams 1B.

En variante, ce type d'installation des vérins 5 peut également être utilisé pour les installations intermédiaires de vérins 5, à la place des poutres de support provisoires 6. Cette variante permet de disposer les vérins 5 à la hauteur hi de pose du plafond 2.As a variant, this type of installation of the jacks 5 can also be used for intermediate installations of jacks 5, in place of the temporary support beams 6. This variant makes it possible to arrange the jacks 5 at the height h i for installing the ceiling 2.

Selon le mode de réalisation décrit ci-dessus, par l'intermédiaire des poutres de pose provisoires 4, le plafond 2 est supporté par des poutres horizontales 1B qui doivent être maîtresses et dimensionnées en conséquence. En variante, la pose et fixation du plafond 2 peut être réalisée sur les pylônes 1A de la structure porteuse 1. Ceci peut être obtenu par exemple en installant sur les pylônes 1A, aux hauteurs hi, des plots de pose 9 latéraux de liaison avec le plafond 2. Cette variante, représentée sur la figure 6, permet d'alléger les poutres horizontales 1B de la structure porteuse 1 et donc nécessite une grue 7 moins puissante.According to the embodiment described above, by means of the temporary laying beams 4, the ceiling 2 is supported by horizontal beams 1B which must be central and dimensioned accordingly. As a variant, the installation and fixing of the ceiling 2 can be carried out on the pylons 1A of the supporting structure 1. This can be obtained for example by installing on the pylons 1A, at heights h i , lateral mounting pads 9 connecting with the ceiling 2. This variant, shown in FIG. 6, makes it possible to lighten the horizontal beams 1B of the supporting structure 1 and therefore requires a less powerful crane 7.

Selon le procédé décrit ci-dessus, la hauteur h1 est sensiblement égale à la hauteur h des parties de chaudière 3.According to the method described above, the height h 1 is substantially equal to the height h of the boiler parts 3.

Les étapes (a) et (b) décrites peuvent être décomposées en plusieurs étapes successives de levage du plafond 2 et de suspension des parties de chaudière 3.The steps (a) and (b) described can be broken down into several successive steps of lifting the ceiling 2 and suspending the boiler parts 3.

Dans ce cas, h1 est inférieure à la hauteur h des parties de chaudière (3) et le procédé comporte également les étapes suivantes:

  • (c) on érige la structure porteuse 1 à au moins une hauteur h2, simultanément à l'étape (b),
  • (d) on lève progressivement le plafond 2 jusqu'à la hauteur h2 et monte successivement des parties de chaudière 3 suspendues dans une position à quelques mètres du sol,
  • on répète les étapes (c) et (d) jusqu'à ce que hi soit sensiblement égale à h.
In this case, h 1 is less than the height h of the boiler parts (3) and the method also includes the following steps:
  • (c) the supporting structure 1 is erected at at least one height h 2 , simultaneously with step (b),
  • (d) the ceiling 2 is gradually raised to the height h 2 and successively raises parts of the boiler 3 suspended in a position a few meters from the ground,
  • repeating steps (c) and (d) until h i is substantially equal to h.

On érige ensuite la structure porteuse 1 à sa hauteur totale H, simultanément à l'étape précédente, comme représenté sur les figures 4 et 5 et on lève ensuite le plafond 2 jusqu'à la hauteur H, grâce aux vérins 5 installés au sommet de la structure porteuse 1, comme représenté sur les figures 5 et 6. Eventuellement des parties de chaudière 3 peuvent encore être montées à quelques mètres du sol, lors de cette dernière opération de levage du plafond 2.The supporting structure 1 is then erected at its total height H, simultaneously with the previous step, as shown in FIGS. 4 and 5 and the ceiling 2 is then raised to the height H, thanks to the jacks 5 installed at the top of the supporting structure 1, as shown in FIGS. 5 and 6. Optionally, parts of the boiler 3 can still be mounted a few meters from the ground, during this last operation for lifting the ceiling 2.
