Description

TITLE

Structural support unit for floorings.

DESCRIPTION

The present invention relates to a structural support unit for floorings, especially, even if not exclusively, for use in the shipbuilding field.

It is known that, to ensure a perfect flatness of carpets, vynil flooring tiles etc., the underlying surface must be perfectly leveled.

The present invention relates, specifically, to the realization of surfaces on which it is possible to apply a flooring made of conventional materials and possibly also a sound insulation layer, ensuring maximum simplicity and speed in carrying out the assembly operations of these surfaces and, at the same time, ensuring the perfect planarity thereof. This result is achieved, according to the present invention, by adopting the idea to realize a module having the characteristics indicated in claim 1. Other features of the present invention are object of the dependent claims.

Further advantages and features of the present invention will be apparent from the following description and the accompanying drawings, given by way of example but not to be considered in ' a limiting sense, wherein:

Fig.l is a schematic perspective view, partially exploded, of a construction module in accordance with the present invention;

Fig.2 is a schematic plan view of a leg;

Fig.3 is a side view of a leg;

Fig.4 is a sectional view along line A-A of Figure 3; Figs 5 and 6 are two views in perspective exploded view of the leg shown in Figs. 2-4;

- Fig.7 is a partial plan view of a longitudinal member;

Fig.8 is a schematic cross-sectional view of the longitudinal member of Fig.7;

- Fig.9 is a partial side view of a cross- member;

- Fig.10 is a partial side view of a longitudinal member.

Reduced to its basic structure and with reference to the attached drawings, a constructive module (M) according to the present invention comprises two longitudinal members (1) connected to each other by cross-members (2) and provided with adjustable legs (3) that are on the lower side of each longitudinal member (1) .

Each leg (3) has a disc-shaped base (30) from whose upper side emerge, orthogonally, a threaded pin (31) having an axial through hole; and an upper connecting part (32) by which the leg (3) is connected with the lower side of the longitudinal member (1) .

With reference to the example shown in the drawings, said connecting part (32) is made by two rings (33, 34) between which there is a rubber dampening cylinder (35) having a central through hole (36) . The unit formed by the two rings (33, 34) and the rubber cylinder (35) is subjected to vulcanization so as to form a single body (32). The lower ring (33) has, at the center, on its upper face, an axial cylindrical extension (37) with internal thread in which is screwed the pin (31) of the base (30) . The upper ring (34) also has, at the center, on its upper face, an axial cylindrical extension (38) but with external thread which is screwed into a corresponding nut thread (12) presented by the lower side of the side member (1 ) at the point where the leg (3) must be connected. In practice, the body (33, 34, 35) is fixed on the lower side of the longitudinal member (1) in the predetermined point, and the discoid base (30) is screwed into the aforementioned extension (37) , such that the height of the foot (3) can be adjusted simply by screwing or unscrewing the base (30) .

The base (30) of the leg (3) has a peripheral edge (39) of predetermined height that defines, in cooperation with the lower surface of the same base (30), a chamber (4) in which it is possible to inject the adhesive as further described in the following.

The point of attachment of the leg to the longitudinal member (1) is perforated. In the drawings, the hole is indicated by the numeral reference "10".

The leg (3) is positioned under the longitudinal member (1) such that the pin (31) passes through the body (32) and is coaxial with the hole (10) .

The body (32) is fixed to the lower side of the longitudinal member (1), while the distance of the base (30) from that side, or the overall height of the foot (3), is adjusted by rotating the pin (31) into the thread of the appendix (37) .

The accessibility of the pin (31) through the hole (10) of the longitudinal member (1) offers the possibility to act on the pin (31) by means of a tool (such as a hexagonal key acting on a portion 38 also formed on the hexagonal head of the pin 31) inserted into the hole (10) so as to adjust the height of the foot (3) by acting from above with respect to the longitudinal member (1); and allows the use of the axial bore of the pin (31) to inject the adhesive into the aforesaid chamber (4) .

In practice, the module ( ) already provided with legs (3) is put on the surface to be paved, and then, by acting on the pin (31) of each leg (3) the

height of the latter is .adjusted up to have the module (M) positioned according to the desired attitude. Subsequently, to secure the module (M) on the surface concerned, the adhesive is injected through the pins (31) by making the adhesive itself to flow in the chamber (4). Practically, the pins (31) act as a channel of communication between the holes (10) and the respective cavities (4) .

It is obtained, therefore, the advantage of being able to adjust the height of the individual legs (3) by acting through the holes (10) after laying the modules (M) on the surface to be paved and to be able to inject the adhesive into the chambers (4) without having to lift the modules (M) .

The adhesive injected into the chambers (4) can be of the type commercially available. For example, it can be used an adhesive commercially known as PROMAT PROMASEAL S.

The cylinder (35) can also be provided with internal reinforcement (formed, for example, by a helical spring of stiffness less than that of the material of which the same cylinder 35 is made) .

Said longitudinal members (1) have, on each flank, a plurality of slots (11) in which are inserted corresponding interlocking projections (21) of the crosspieces (2) . This allows to realize a modular structure with modules (M) fixed to one another by means of interlocking instead of by means of screws or welds as in traditional systems.

Preferably, said slots (11) are arranged such that a slot (11) is on the left and another one is on the right of each hole (10) .

As shown in Fig.10, preferably said slots (11) extend on the sides of the side members (1) having, on these sides, an "L"-shaped profile with the horizontal part (110) wider than the vertical part (111) to facilitate the positioning of said projections (21) during assembly of the modules (M) . The connection of the longitudinal members (1) by means of the crosspieces (2) formed by interlocking of the projections (21) in the slots (11) prevents, or at least minimizes, the use of screw means and welding normally used to assemble this type of structures .

The longitudinal members (1) are formed by bending of metal sheets of the type normally used in this field.

The longitudinal members (1) can be covered with a sound insulation material (for example the material commercially known as PROMAT PROMASOUND TL) and/or dampening material for example the material commercially known as PROMAT PROMADAMP CL SK) .

The desired flooring is positioned on the modules (M) . For example, the flooring positioned on the modules (M) can be the flooring commercially known as PROMAT SYSTEMFLOOR.

In practice the details of execution may vary in any equivalent way as for what concerns the shape, arrangement and number of the individual elements described, without departing from the scope of the adopted solution and thus remaining within the limits of the protection granted by this patent.
