  Process for assembling the constituent elements of a boiler in.

  for.te and devices for carrying out this method.

  Currently most accessories of boilers in fontu:

  hoses, Ltrappeu de l '' lIonige,) nozzles, burner support plates, habi] -

  lages ... are fixed with screws, through holes peri '(s and.

  tapped into the elements of the cast iron heater.

  This method of attaching accessories and other items requires

  machining, its cost is high.

  The object of the present invention is to provide a less expensive assembly method while simplifying the assembly of parts, this goal has been achieved by achieving a universal mode of attachment that is to say, able to fix or receive indifferently l any of the boiler accessories mentioned above.

  The invention will be better understood on reading the description of

  after, made with reference to the appended figures for which: - Figure 1 is a perspective view of a first example of

  realization of a facade element for cast iron boiler.

  FIG. 2 is a technical equivalent of the first exemplary embodiment. FIGS. 3, 4, 5, 6, 7, 8 show different modes of assembly which can be provided on the front element or elements of the cast iron boiler.

  - Figure 8a shows on a larger scale a tab of laz 'igur-t.

  The embodiment shown in FIG. 1 is given to

non-limiting example.

  FIG. 1 shows in perspective a front element (1) having the rear end of a boiler (2) made of cast iron, comprising covering panels (t),

  the other constituent elements not being reprocessed.

  The facade element (1) comprises one or more peripheral nervdis (4l) directly from the foundry, having a plurality of housings (5) for receiving fastening accessories: char'n.% Re (6),

  bolts or clips not shown etc ...

  The embodiment shown in FIG. 2 is an equivalent

technique of that of Figure 1.

  The front element (1) shown in FIG.

  periphery, a plurality of auricles (7) coming directly from londer, ..

  Each ear (7) has a fastening plane (7a) and two tabs ('b) perpendicular to the plane (7a) to ensure rigidity and strength. The fixing plane (7a) comprises at least one light whose function is the

  same as the housing (5) of Figure 1.

  According to the two embodiments, the plane for fixing the ribs (4) or the lugs (7) is perpendicular to the main plane (la) of

the facade element (1).

  The facade element (1) may be a front facade element or a rear facade element, it may comprise, as the case may be, a cylindrical boss (8) coming from a foundry to cooperate with a flue nozzle (9) ( facade

  rear) or a hatch (10) (front panel).

  Two modes of attachment of nozzle or trap are presented in FIGS.

  and 4, by way of non-limiting examples.

  In FIG. 3, the boss (8) has two lugs (11) comprising

  each a fixing light (lia) coming from foundry.

  It is expected, on the smoke nozzle (9) two ears (12) comprising

  each a light (12a), placed next to the lights (11a).

  The assembly (nozzle (9) - boss (8)) is made by means of bolts.

  In FIG. 4, the boss (8) also has two lugs (11) with lights (11a), the intermediate nozzle (9) has two lugs (13) perpendicular to the axis of the nozzle and having two holes (13a) come from foundry, the hatch (10) has two ears or extensions with holes (14a). The assembly of the three parts (hatch (10), nozzle (9), boss (8) is produced by means of bent screws (15) passing through the holes (13a) and (14a), positioned as shown in FIG. cooperating with nuts (not shown) 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 by way of example

in Figure 5.

  The front element (1) comprises at least one blocking rib (16) coming from a casting, the thickness of which is, for example, less than that of the element (1), at least partially closing a cavity or notch of

  fastening (17) provided on the periphery of the facade element (1).

  The locking rib (16) has a lumen or a housing (18), preferably open, for receiving a threaded connecting rod (18) of the not shown heating elements. The assembly is carried out by washer system (19) and nut (20) in known manner, a ridge (16a) coming from casting on the rib (16) prevents slippage of the washer (19) towards

outside and serves as stops.

  Figures 6, 7, 8 show 3 variants of the assembly means of

  cladding panels (3) with the facade element (1).

  In FIG. 6, the front element (1) has on its circumferential flanks

  a plurality of pins (21) coming from the foundry and cooperating with - 3 -

clips (22).

  The pin assemblies (21) and clips (22) simultaneously hold and position the insulation (23) and the cladding (3). FIG. 6a shows in detail an assembly, the pin (21) comprises a body (21a). ) of a length appropriate to the thickness of the insulation (23) and a head (21b) suitable for

receive a clip (22).

  According to another variant represented in FIG. 7, the panels of

  Lage have "L" -shaped fastening notches (24) cooperating by gravity with bushes (25) to be attached to lugs (7) or to the ribs (4) previously described. The notches (24) are made

  in a folding strip (3b) parallel to the panel (3).

  According to another variant represented in FIG. 8, the hatch panel

  blasting (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).

  Said folding strip (3b) comprises at least one notch (27), for

rectangular example.

  There is provided a tab (26), for example 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) by 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).

  FIG. 8a shows on a larger scale a reversible lug (26) which preferably has 2 slots (26b) for an assembly on the left or on the right

of the facade element (1).

  Of course, for the sake of clarity, only one boiler facade panel has been included in the diagrams, but the boiler may have two, each of which may include one or more of the elements of the boiler. assembly that have just been described, depending on the type of boiler on

which it will be mounted.

  Compared with the facade elements of the prior art, the facade element according to the invention has, whatever the variant chosen, manufacturing advantages (economy of foundry core), machining (which is reduced). or zero), on the assembly plan (which is simplified), and

  this results in a decrease in the cost price of the boiler.

  Whatever the implementation variant chosen, the method for assembling the constituent elements of the boiler is therefore characterized in that said constituent elements (9, 10, 3, 23 ...) are maintained by one at least front elements (1), front and / or rear, of the

boiler.

2590002-

  - 4 - The variants of implementations are characterized in that they consist at least of a front-rear facade element (1) comprising at least one element of the type (rib (4) (16), ear ' 7), boss (8), pin 2 ') Foundry gains with said facade element, and provided for fixing at least one of the other elements of the boiler.

  Throughout the description and the claims it will be understood that the

  terms "come (s) of foundry" mean "come (s) of foundry with the element of facade (1)", and that the shapes of the ribs, ears, bosses and spikes are non-limiting examples whose variants will be considered as

technical equivalents.
