Selon les deux variantes de réalisation, le plan de fixation des nervures (4) ou des oreilles (7) est perpendiculaire au plan principal (la) de l'élément de façade (1).According to the two alternative embodiments, the plane of attachment of the ribs (4) or the ears (7) is perpendicular to the main plane (la) of the facade element (1).
L'élément de façade (1) peut être un élément de façade avant ou un élément de façade arrière, il peut comporter selon le cas un bossage cylindrique (8) venu de fonderie pour coopérer avec une buse (9) de fumées (façade arrière) ou une trappe (10) (façade avant).The facade element (1) can be a front facade element or a rear facade element, it can comprise, as the case may be, a cylindrical boss (8) coming from the foundry to cooperate with a smoke nozzle (9) ) or a hatch (10) (front panel).
Deux modes de fixation de buse ou de trappe sont présentés en figures 3 et 4, à titre d'exemples non limitatifs.Two methods of fixing the nozzle or hatch are presented in FIGS. 3 and 4, by way of nonlimiting examples.
A la figure 3, le bossage (8) présente deux oreilles (11) comportant chacune une lumière de fixation (11a) venue de fonderie.In Figure 3, the boss (8) has two ears (11) each comprising a fixing lumen (11a) from the foundry.
On prévoit, sur la buse de fumées (9) deux oreilles (12) comportant chacune une lumière (12a), placées en regard des lumières (lla).There are two ears (12) on the smoke nozzle (9) each comprising a light (12a), placed opposite the lights (lla).
L'assemblage (buse (9) - bossage (8)) est réalisé au moyen de boulons.The assembly (nozzle (9) - boss (8)) is carried out by means of bolts.
A la figure 4, le bossage (8) présente également deux oreilles (11) avec lumières (lla), la buse intermédiaire (9) comporte deux oreilles (13) perpendiculaires à l'axe de la buse et présentant deux trous (13a) venus de fonderie, la trappe (10) comporte deux oreilles ou prolongements avec trous (14a).In Figure 4, the boss (8) also has two ears (11) with lights (lla), the intermediate nozzle (9) has two ears (13) perpendicular to the axis of the nozzle and having two holes (13a) Coming from the foundry, the hatch (10) has two ears or extensions with holes (14a).
L'assemblage des trois pièces (trappe (10), buse (9), bossage (8) est réalisé au moyen de vis coudées (15) traversant les trous (13a) et (14a), positionnées comme le montre la figure 4 et coopérant avec des écrous non représentés.The assembly of the three parts (hatch (10), nozzle (9), boss (8) is carried out by means of angled screws (15) passing through the holes (13a) and (14a), positioned as shown in Figure 4 and cooperating with nuts not shown.
On peut encore prévoir sur l'élément de façade (1) un ou une pluralité de moyens pour fixer les tiges d'assemblage, on se reportera à titre d'exemple à la figure 5.It is also possible to provide on the front element (1) one or a plurality of means for fixing the assembly rods, reference will be made, for example, to FIG. 5.
L'élément de façade (1) comporte au moins une nervure de blocage (16) venue de fonderie, dont l'épaisséur est par exemple inférieure à celle de l'élément (1), obturant au moins partiellement une cavité ou une encoche de fixation (17) prévue sur le pourtour de l'élément de façade (1).The facade element (1) comprises at least one blocking rib (16) from the foundry, the thickness of which is for example less than that of the element (1), at least partially closing a cavity or a notch of fixing (17) provided on the periphery of the facade element (1).
La dite nervure de blocage (16) présente une lumière ou un logement (18), de préférence ouvert, pour recevoir une tige d'assemblage filetée (18) des éléments de chauffe non représentés. L'assemblage est réalisé par système rondelle (19) et écrou (20) de façon connue en soi, une arête (16a) venue de fonderie sur la nervure (16) empêche le glissement de la rondelle (19) vers l'extérieur et sert de butées.Said locking rib (16) has a slot or housing (18), preferably open, for receiving a threaded assembly rod (18) of the heating elements not shown. The assembly is carried out by washer system (19) and nut (20) in a manner known per se, an edge (16a) coming from foundry on the rib (16) prevents the sliding of the washer (19) outwards and serves as stops.
Les figures 6, 7, 8 montrent 3 variantes des moyens d'assemblage des panneaux d'habillage (3) avec l'élément de façade (1).Figures 6, 7, 8 show 3 variants of the means of assembling the covering panels (3) with the facade element (1).
Sur la figure 6, l'élément de façade (1) comporte sur ses flans périphériques une pluralité de picots (21) venus de fonderie et coopérant avec des clips (22).In Figure 6, the facade element (1) has on its peripheral blanks a plurality of pins (21) from the foundry and cooperating with clips (22).
Les ensembles picots (21) et clips (22) maintiennent et positionnent simultanément l'isolation (23) et l'habillage (3) - La figure 6a montre en détail un assemblage, le picot (21) comporte un corps (21a) de longueur appropriée à l'épaisseur de l'isolation (23) et une tête (21b) appropriée pour recevoir un clip (22).The sets of pins (21) and clips (22) simultaneously maintain and position the insulation (23) and the covering (3) - Figure 6a shows in detail an assembly, the pin (21) comprises a body (21a) of length appropriate to the thickness of the insulation (23) and a head (21b) suitable for receiving a clip (22).
Selon une autre variante représentée en figure 7, les panneaux d'habillage présentent des encoches de fixation (24), en forme de "L", coopérant par gravité avec des douilles (25) destinées à être fixées sur des oreilles (7) ou sur les nervures (4) décrites précédemment. Les encoches (24) sont réalisées dans une bande de pliage (3b) parallèle au panneau (3).According to another variant shown in FIG. 7, the covering panels have fixing notches (24), in the shape of an "L", cooperating by gravity with sockets (25) intended to be fixed on ears (7) or on the ribs (4) described above. The notches (24) are produced in a folding strip (3b) parallel to the panel (3).
Selon une autre variante représentée en figure 8, le panneau d'habillage (3) présente sur ses côtés une bande de pliage (3a), comme en figure 7, perpendiculaire au plan du panneau (3), et une bande de pliage (3b) parallèle au plan du panneau (3).According to another variant shown in FIG. 8, the covering panel (3) has on its sides a folding strip (3a), as in FIG. 7, perpendicular to the plane of the panel (3), and a folding strip (3b ) parallel to the plane of the panel (3).
La dite bande de pliage (3b) comporte au moins une encoche (27), par exemple rectangulaire.Said folding strip (3b) comprises at least one notch (27), for example rectangular.
On prévoit une patte (26), par exemple en tôle et obtenue par pliage, comportant un perçage (26a) et une fente (26b). La dite patte (26) coopère d'une part avec le panneau (3) par la fente (26b) et d'autre part avec une des oreilles (7) par système vis-écrou. Le panneau (3) est maintenu dans la fente (26b) par gravité au niveau de l'encoche (27).A tab (26) is provided, for example made of sheet metal and obtained by folding, comprising a bore (26a) and a slot (26b). Said tab (26) cooperates on the one hand with the panel (3) through the slot (26b) and on the other hand with one of the ears (7) by screw-nut system. The panel (3) is held in the slot (26b) by gravity at the notch (27).
La figure 8a montre à plus grande échelle une patte (26) réversible qui comporte de préférence 2 fentes (26b) pour un assemblage à gauche ou à droite de l'élément de façade (1).FIG. 8a shows on a larger scale a reversible tab (26) which preferably comprises 2 slots (26b) for an assembly on the left or on the right of the facade element (1).
Bien entendu, par souci de clarté, on n'a fait figurer sur les schémas qu'un panneau de façade de chaudière, mais la chaudière peut en comporter 2, chacun pouvant comporter l'un 'ou l'autre ou plusieurs des éléments d'assemblage qui viennent d'être décrits, selon le type de chaudière sur laquelle il sera monté.Of course, for the sake of clarity, only the boiler front panel has been shown in the diagrams, but the boiler may include 2, each of which may include one or the other or more of the elements of 'assembly which have just been described, depending on the type of boiler on which it will be mounted.
Par rapport aux éléments de façade de l'art antérieur, l'élément de façade conforme à l'invention présente, quelle que soit la variante choisie, des avantages au plan fabrication (économie de noyau de fonderie), au plan usinage (qui est réduit ou nul), au plan montage (qui est simplifié), et il en résulte une diminution du prix de revient de la chaudière.Compared to the facade elements of the prior art, the facade element according to the invention has, whatever the variant chosen, advantages in terms of manufacturing (economy of foundry core), in terms of machining (which is reduced or zero), on the assembly plan (which is simplified), and this results in a reduction in the cost price of the boiler.
Quelles que soient les variantes de mise en oeuvre choisies, le procédé d'assemblage des éléments constitutifs de la chaudière se caractérise donc en ce que les dits éléments constitutifs (9, 10, 3, 23...) sont maintenus par l'un au moins des éléments de façade (1), avant et /ou arrière, de la chaudière.Whatever the implementation variants chosen, the method of assembling the constituent elements of the boiler is therefore characterized by that the said constituent elements (9, 10, 3, 23 ...) are held by at least one of the front elements (1), front and / or rear, of the boiler.
Les variantes de mises en oeuvre se caractérisent en ce qu'elles se composent au moins d'un élément de façade (1) avant-arrière comportant au moins un élément du type (nervure (4) (16), oreille (7), bossage (8), picot (21) venus de fonderie avec le dit élément de façade, et prévus pour la fixation d'au moins l'un des autres éléments de la chaudière.The variant embodiments are characterized in that they consist of at least one front-rear element (1) comprising at least one element of the type (rib (4) (16), ear (7), boss (8), pin (21) from the foundry with said facade element, and provided for fixing at least one of the other elements of the boiler.
Dans toute la description et les revendications on comprendra que les termes "venu (s) de fonderie" signifient "venu (s) de fonderie avec l'élément de façade (1)", et que les formes des nervures, oreilles, bossages et picots sont des exemples non limitatifs dont les variantes seront considérées comme des équivalents techniques.Throughout the description and the claims, it will be understood that the terms "foundry member (s)" mean "foundry member (s) with the facade element (1)", and that the shapes of the ribs, ears, bosses and pins are non-limiting examples, the variants of which will be considered as technical equivalents.
