Description
- The present invention relates to a supporting structure particularly but not exclusively for modular flooring elements.
- It is known that in recent times there is an increased use of raised floors constituted by a plurality of modular plate-like elements made of various flooring materials, such as slabs or crushed-marble tiles made of natural and synthetic stone-like materials, supported at a variable height from a bottom surface, usually made of concrete, by a metal frame which is in turn supported by a plurality of spacer posts which rest on the bottom surface.
- Examples of raised floors are available from documents DE-A-3 721 195, DE-U-85 31 810 and FR-A-2 662 728.
- DE-A-3 721 195, in particular, discloses features comprised in the preamble of
claim 1. - The aim of the present invention is to provide an improved supporting structure for modular flooring elements which allows quick installation and ensures high stability and reliability over time.
- Within the scope of this aim, an object of the present invention is to provide a new coupling node in the supporting frame which ensures the provision of stable and safe connections among a plurality of frame elements.
- Another object of the present invention is to provide a supporting structure which can be manufactured at a very low cost.
- This aim, these objects and others which will become apparent hereinafter are achieved by a supporting structure, according to the invention, having the features set forth in
claim 1. - Advantageously, each base trunk comprises a base sleeve in which one end is rigidly coupled to a plate or pedestal for resting on the ground or on the floor and the other end is affected by a threaded nut in order to allow to adjust and set the height of the post to the chosen level.
- The present invention is described in greater detail hereinafter with reference to the accompanying drawings, wherein:
- figure 1 is a front elevation view, with parts shown in cross-section, of a portion of a supporting structure according to the present invention at a supporting post;
- figure 2 is a front elevation view, similar to figure 1, of a second embodiment at the region for joining a raised floor to the supporting frame of an overlying machine;
- figure 3 is an enlarged-scale plan view, with some parts shown in cross-section, of the structure of figure 1;
- figure 4 is a front elevation view, with some parts shown in cross-section, of a supporting base for a base trunk or telescopic post;
- figures 5, 6 and 7 are respectively a plan view, a side view and a front view of an upper plate;
- figure 8 is a front elevation view of an upper plate or head with four recesses, rigidly coupled to a threaded stem;
- figure 9 is a bottom view of the plate of figure 8;
- figures 10 and 11 are front views of a C-shaped profiled element having respectively a rectangular hollow and a square hollow and constituting the horizontal frame of the structure;
- figure 12 is a partial plan view of a wing nut; and
- figure 13 is a sectional view, taken along the plane XIII-XIII of figure 12.
-
- In the various figures of the accompanying drawings, identical or similar parts or components have been designated by the same reference numerals.
- With reference to the above figures, a supporting
structure 1 according to the present invention is formed by a plurality of supportingposts 2 for resting on aresting surface 3, by a plurality ofstringers 4 andtubular cross-members 5 with alongitudinal slot 6 which form a supporting frame for a plurality ofmodular flooring elements 7. - Each supporting
post 2 comprises atrunk 8, astem 9 which can be telescopically coupled to the trunk orpost 8, for example by screwing therein or by simple insertion with adjustment of the position by means of anut 14, and an upper plate orhead 10 with fourcrossing recesses 11 provided with a respective notch orslot 12. Thetrunk 8 is formed by a sleeve the lower end whereof is fixed, for example welded, to a plate orpedestal 13 for resting on the ground or on thefloor 3, while its upper end constitutes the resting and contrast element for thenut 14 that is normally screwed on the threadedstem 9. - The upper plate or
head 10 abuts against thestem 9 and is fixed below it, for example welded (figure 8), while in an upward region it has two pairs of alignedshoulders slotted recesses 11 and form the seat for accommodating the tubular profiledelements - The
plate 10 has a substantially rectangular configuration and is meant to constitute a resting and locking element for the ends of twostringers 4 and of one or twocross-members 5. Arecess 11 thereof, located at a longer side of theplate 10, has anextension 17 in order to increase the resting surface for thetubular stringers 4 andcross-members 5. The asymmetrical shape and support of theplate 10 against thestem 9 allows to easily form perimetric structure regions, for example at the area of contact with walls, where the system of stringers and cross-members must form a T. - The stringers and the cross-members can be constituted by a same C-shaped profiled element (figure 2) with a longitudinal slot 6 (figure 1) or by profiled elements having a different cross-section, for example a rectangular or square one (figure 2).
- The means for removably mutually fixing the
plate 10 and the tubular stringer orcross-member bolts 19 the head whereof abuts against the lower face of theplate 10 and the threaded stem whereof passes through arespective notch 12 to screw into a respective rhomboid nut 20 (figures 1 to 3, 12 and 13) inserted beforehand through theslot 6 into the overlying stringer or cross-member. Eachnut 20, during use, engages against the inside walls of the respective profiled element (figure 3), so that it is possible to quickly and safely tighten thebolts 19 by acting only on the head of said bolts. - A structure is thus obtained which is resistant not only to vertical stresses but also to horizontal stresses, such as for example the dynamic stresses produced by moving vehicles.
- The above-described supporting structure is susceptible of numerous constructive modifications and variations within the protective scope defined by the appended claims.
- The materials and the dimensions may be various according to requirements.
- Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly, such reference signs do not have any limiting effect on the interpretation of each element identified by way of example by such reference signs.
