According to a preferred embodiment, the opposite parts of the annular non ^- supporting plate 10 passing through the socket 3 are preferably ^rectilinear , or these parts have the same so that each annular non-supporting plate 10 can be connected to the head 7 and base 6 of the structure 1 in a manner completely similar to the respective annular supporting plates 2, 2 ^I , . . . , 2 ^N.

In the example shown in the figures, each annular non-bearing plate 10 has a polygonal outer perimeter configuration. In any event, it is to be understood that the annular non ^- supporting plate 10 may have any outer perimeter configuration, for example circular or elliptical, so long as the configuration does not interfere between two consecutive annular supporting plates 2, 2 ^I , . . . The device 8 for connection is enough.

In any case, nothing prevents the base 13 of the support means 11 from extending transversely along the entire in-use underside of the respective annular support plate 2, ^2I , ..., ^2N or along a part of this underside, so that, depending on the case, The base 13 supports the respective ^annular support plates 2, 2 ^I , .

According to a preferred variant of the structure for the pressing device, the transverse walls 14 and 15 comprise two respective flat sections arranged perpendicular to the axis xx; in each section a through opening 16 is obtained.

The through openings 16 of each transverse wall 14 , 15 are aligned with each other on the same axis zz substantially parallel to said axis xx and are intended to receive the fixing means 12 in use. For this purpose, also in the ^annular support plates 2 , 2 ^I , .

Fixing means 12 comprises at least one pin constrained to each transverse wall 14 and 15 in any suitable manner. In any event, it is understood that any other suitable removable fixing means may be implemented at the transverse walls 14 and 15, such as calibration screws with, for example, threaded shafts, and if desired Through-holes 16 are formed with threads of the same pitch. Furthermore, any suitable removable fixing means may be provided, as long as they allow a firm engagement between the support means 11 and the respective annular support plate 2, ^2I , ..., ^2N .

As will be observed, in some cases the fixing means 12 may be of a type that does not require through-openings to be obtained in the support means 11, nor in the respective annular support plates 2, 2 ^I , . . . , 2 ^N obtains a through opening.

The supporting device 11 for a structure for pressing equipment according to the invention may also comprise adjusting means, such as a plurality of adjusting screws 17, intended to adjust the position of the structure for pressing equipment so that the structure rests evenly on the ground . Each adjusting screw 17 is arranged to pass through a corresponding base 13 of the support device 11 , the adjusting screw being screwable in and out of a corresponding housing 18 obtained in the base 13 if required. The in-use lower end of each adjusting screw is intended to rest on the ground or base or plate on which the structure for the pressing apparatus is mounted. Preferably, for ^each base 13 of the support means 11, as ^seen in FIG. 2, two The adjusting screw 17 is arranged in a corresponding housing 18 obtained on the opposite side. Each screw 17 can be screwed in and out of a corresponding seat 18 by means of a corresponding adjusting nut 19 in a known manner.

With this construction, the person skilled in the art will readily understand that, once the structure for the pressing device is assembled, it is possible to adjust the position of the structure by means of the adjusting screw 17 and adjusting nut 19, and, once the desired position has been achieved , it is possible to constrain the structure to the ground or base or plate on which it rests by welding each base 13 to the ground or base or plate.

As will be readily understood, the above-described non-welded structure for the pressing apparatus 1 can be assembled easily and quickly.

The assembly process begins with arranging the annular support plates 2, ²¹ , ..., ^2N next to each other and preferably at a distance from each other, wherein the individual through-seats 3 are aligned along the same longitudinal axis of symmetry xx. The ^annular support plates 2, 2 ^I , .

^Next , the head 7 is fixed to all or some of the ^annular support plates 2, ^{2 I ,} . The base 6 of the structure 1 is also fixed to all or some of the annular support plates 2, 2 ^I , . . . , 2 ^N . The method for assembling the structure for the pressing device is to constrain the two continuous annular support plates 2, 2 ^I , ..., 2 ^N by means of the above-mentioned connecting means 8 before or after the step of connecting the head 7 and the base 6 together such that each intermediate annular support plate (2 ^I , . . . , 2 ^{N -1} ) is connected in use to the preceding plate and the rear board.

If the structure for the pressing apparatus according to the invention comprises at least one annular non-supporting plate 10, the method consists in constraining successive pairs of annular supporting plates 2, 2 ^I , ..., 2 ^N together by means of connecting means 8 Before the step, and before fixing the base 6 or the head 7, at least one annular non-supporting plate 10 is arranged between at least one annular supporting plate 2, 2 ^I , . . . , 2 ^N and the next annular supporting plate. In this case, the respective annular support plates 2, 2 ^I , ..., 2 ^N will be arranged parallel to each other at a distance sufficient for interposing at least one or more annular non-support plates 10 between the respective annular support plates . Thus, the step of fixing the base 6 and the head 7 to the structure 1 in this case also includes fixing the head 7 and the base 6 to all or some of the annular non-bearing plates 10, so that the head 7 and the base are firmly connected to Annular unsupported plate 10 .

Thus, it will be appreciated that the above described non-welded structure for a pressing device solves the technical problem outlined. This structure allows obtaining a non-welded structure for pressing equipment. The structure is easy to transport as it is lightweight and detachable. The structure can be easily installed since it is provided in any case with a limited number of components. Furthermore, the construction according to the invention for a pressing plant has a lower weight for the same dimensions compared to conventional constructions of a pressing plant provided only with a support plate. The means 8 for connecting between two successive ^annular support plates 2, 2 ^I , .

In particular, the non-welded structure 1 for pressing equipment according to the invention has a particularly easy assembly process since only some of the annular plates making up the structure are support plates, i.e. only some of these need to be fixed to the ground .

For example, in the presented embodiment, out of a total of 15 annular plates constituting the structure 1, only eight are bearing plates, while the rest are constituted by annular non-supporting plates 10, which are easily connected by means of connecting means 8. Constrained to other support plates.

As will be appreciated, this approach allows to significantly limit the assembly time relative to conventional types of structures.

However, as the annular non-supporting plate 10 helps to give the structure the necessary rigidity and strength during execution of the product pressing cycle, doing so does not result in any impairment of the performance of the structure in operation.

Another significant advantage deriving from the complete absence of welding between the annular plates forming the structure of the pressing device consists in the fact that the annular plates themselves can thus be made of non-weldable materials, i.e. Weldable steel Higher quality steel for use in press equipment for large format ceramic products.

The above-described structure for the pressing device and its method of assembly are susceptible to various modifications and variations.
