Base for the construction of raised floors

The present invention relates to a base for the construction of raised floors.

5 The raised floors are made by placing modular panels on a plurality of bases capable of supporting them at the corners, with the possible presence of spacers which connect these same bases to each other.

Given the possibility of encountering expensive plan-10 or insufficiently flat or non-flat bearing surfaces. horizontal, these bases have an adjustable length so as to be able to compensate, within certain limits, for these same irregularities, so as to be able to produce a perfectly flat and horizontal floor.

The support base of these bases is usually made by stamping, in a metallic material, and is designed sufficiently wide to ensure the stability of the base itself. However, due to this same characteristic, it proves to be ill-suited to rely on regular or rough ir-20 slabs.

In practice, we have to face the problem that the base is only supported by a single point on its base, which has the consequence of creating a lack of stability.

The object of the present invention is therefore that of providing a base for raised floors capable of eliminating the problems associated with the drawbacks mentioned above.

Another object of the invention is that of providing a base with a support base capable of adapting even to locally irregular surfaces.

Another object of the invention is to provide a base capable of ensuring stability in any support condition, even on irons or regular ir-35 slabs.

Another object of the invention is to provide a base in which the weight of the floor and the objects placed on it can always be discharged along the axis of the base.

Without being the last, yet another object of the present invention is to provide a base which can allow the installation of the floor without the need to provide a special preparation of the support base 5.

These aims, as well as others which will appear more clearly hereinafter, are achieved by a base for raised floors comprising a support head, a rod and a support base, characterized in that said base 10 of support comprises an essentially cylindrical body associable with the lower part of said rod, on said body ♦ being welded a deformable support plate thanks to the presence of one or more circumferential undulations.

Other characteristics and advantages of the in-vention will emerge more clearly from the detailed description which follows of a preferred, but not exclusive, embodiment given here by way of nonlimiting example with regard to the appended drawing, in which: Figure 1 shows a side view of the base according to the invention, with a sectional view of the support base, supporting a panel floor; 2 shows the base of Figure 1 with a sectional view of the support base along a median plane; FIG. 3 represents the same support base of the base, in section on a median plane, in the condition of support on an irregular bottom.

According to the figures, the base according to the invention essentially comprises an upper support head 1, a vertical rod 2 and a support base 3.

30 On the support head 1 come to bear the panels 4 which constitute the floor either directly or with the interposition of a reticle of spacers not shown in FIG. 1.

The length of the rod 2 is variable by screwing 35 of the head 1 or of the base 3.

The support base 3 is constituted by a cylindrical body 5, integral with or screwed onto the lower part of | the rod 2 onto which a deformable support plate 7 is welded, along a circumferential line 6.

This plate 7, preferably obtained by stamping from a metal sheet disc, has one or more circumferential undulations produced so as to have, according to the sectional view of FIG. 2, 5 at least one flat outer circular ring 8 , at least one raised area 9 where welding 6 takes place, and a central support boom 10 which is at the same level as the crown 8.

In the case of an irregularity 11 of the support base 10 12, while the load is still transmitted to the latter especially through the bending 10, the circular crown 8 is deformed 3 allowing the adaptation of the plate 7 and the stability of the base.

Ultimately, the central zone characterized by the presence of the bending 10 transfers the entire load to the support bottom 12, while the deformability of the plate 7 allows stable support on any support bottom.

The circumferential undulations may be as many as one or more. On the other hand, the depth of these pendulations may be different.

It appears from the above that the envisaged goals are all achieved, thanks to the production of a base which proves to be stable and secure in any support condition, thereby making it easier and less costly to produce and the implementation of raised floors.

As far as the materials and the dimensions are concerned, it goes without saying that these can be any i according to the requirements.
