Definitions
- the present invention relates to some improvement features made to the support columns used to lay down superelevated modular flooring.
- the superelevated modular flooring is made up of a structure which can be composed of single height adjustable columns, or (more frequently) columns that are interconnected by cross-beams, upon which the panels are supported and possibly fixed.
- the support column of the panels is extremely important and it should be made in such a way as to satisfy all of the following main requirements.
- the support column should first of all be height adjustable, in a simple, fast and convenient manner for the staff in charge of laying the flooring, in order to allow for perfect reciprocal levelling of the panels.
- the height adjustability of the support column should also be possible once the floor has been laid, removing the smallest number of panels possible, preferably just one.
- the structure of the column should allow for the creation of columns of different heights, according to requirements, without having the precise need of having available more special components, especially produced for the objective, with the obvious inconveniences that may arise.
- the support column should have a structure which may be produced at a low cost, with the possibility of assembly starting from all of the loose components (separate) and starting from the different undergroups which may be assembled reciprocally.
- the column structure should be capable of supporting heavy loads even though of a small size (diameter).
- the height of the support column should be finely adjusted (micrometric regulation) and slackening means should be provided for to prevent possible variations in the predefined adjustment, due to the vibrations that the floor is submitted to, originating from the various levels of strength.
- the regulation mechanism of the column should be completely hidden, in order to create a column with the most pleasant appearance possible, especially for flooring made with transparent materials, such as glass for example.
- the general object of the present invention is that of creating a height adjustable support column, for superelevated modular flooring, capable of satisfying all of the above mentioned requirements.
- Column 10 is structurally made up of a support base 11 and a top support 12 aimed at receiving, directly the panels 13 of the floor, or a system of cross beams 14 upon which these panels 13 rest (Figure 8).
- the base 11 and the top support 12 are interconnected by means of telescopic support 15 ( Figures 13, 14) containing the height adjustable mechanism (hidden) of the column 10.
- such telescopic support 15 includes a first internal tubular element 16 trigged, for example for interference, on a male pierced attachment 17 which extends centrally from the base 11. In this way, the base 11 and the internal tubular element 16 are firmly fixed between themselves.
- a second external tubular element 18 is mounted and translates, which is also fixed to the support 12.
- the support 12 is structurally formed by a glass 19 upon which the external tubular element 18 is fitted with interference.
- the bottom of this glass 19 has a hole 20, while numerous spokes 21 appear from its top edge (in the example illustrated, there are four), aimed at receiving the panels 13 and the cross beams 14 ( Figure 8).
- the height of the telescopic support 15, and therefore of the column 10, can be adjusted by a micrometric adjustment mechanism which is generally accessible from the top, and is completely contained within the telescopic support 15 itself.
- Such micrometric adjustment mechanism is a screw mechanism 22 and a female screw 23, wherein the female screw 23 is blocked with interference at the top of the internal tubular element 16, while the screw 22 is fitted, at the highest extremity, with a manoeuvre head 24, which is easily adjoined against the pierced base 25 of the glass 19. Furthermore, the head 24 of the screw 22 has a seat 26, for example hexagonal, which can be accessed through the hole 20 of the glass 19, for a manoeuvre tool 27 ( Figure 8).
- the female screw 23 presents, for example, lines 28 or similar (conicity) for stable coupling with interference, at the top of the internal tubular element 16. In this way, the female screw 23 is inserted using pressure into the tubular element 16 until it reaches one of its circumferential undercuts 29 against the edge of the tubular element 16 itself.
- the height adjustable mechanism of the column 10 includes a washer which is resiliently pliable 30 ( Figures 1, 12, 13, fitted onto the screw stem 22 and abutting against the lower face of the head 24.
- the screw stem 22 has an unthreaded restraint area 33 ( Figure 9) with gripping ridges (or equivalent).
- such washer 30 has a series of interspaced external circumferential teeth 31, slightly bent (just a few degrees) downwards, and a series of internal teeth 32, intercalated to teeth 31, bent downwards, by approximately 90°, in order to identify a stop neck which puts pressure on the stem of the screw 22, opportunely predisposed with the above mentioned area 33 of fixing.
- the external teeth 31 act using a friction movement over the internal surface area of the external tubular element 18, as illustrated in the Figures, in particular in Figure 9.
- FIGS 14-16 illustrate another possible realization of the support column of the present invention, where similar elements are indicated with the same reference numbers.
- the washer 30 is not present and a support 112 is provided for, of an almost flat shape, welded to the external tubular element 18.
- the hole 20 provides for four stalks 40 placed at 90° from one another, aimed at abutting against a border 41 made above the head 24 of the screw 22 and engaging itself with it.
- the head 24, furthermore, has a central protuberance 42 which fixes itself between the hole 20 and the housing 26 is left empty for the maneouvre tool 27.
- the stalks 40 of any number whatsoever, engage themselves with the head 24 of the screw 22 and prevent unscrewing even in this case.
- the support columns 10 of the tubular flooring are placed on the concrete slab of the building, and possibly fixed to the base 11, and possibly also interconnected between themselves, using the cross beams 14, as illustrated in Figure 9.
- the height adjustment of the column 10 is conveniently carried out from above, without any problems whatsoever for the operator, using the tool 27 (or any other tool suitable for the task, introduced - through the pierced bottom of the glass 19 - in the housing 26 of the head 24 of the screw 22), in the screwing or unscrewing direction, as indicated by arrows 33 of Figure 8, depending if the height of the column 10 is to be increased or reduced.
- We must point out that such an operation may be carried out automatically through the use of motorized systems that are controlled by level sensors.
- the prefixed height of the column 10 is guaranteed throughout time, even in the presence of relevant stresses transmitted by the overhanging flooring.
- the column support 10 can be reached simply by removing just one of the panels 13 which puts pressure on it, as illustrated in Figure 8, through the introduction from above of tool 27 which can be inserted into the hexagonal head 26 of the head 24 of the screw 22 passing easily through the hole 20 at the bottom of the glass 19.
- Another important advantage of the support column according to the invention is that columns of different heights are achieved by simply modifying the length (an operation that can easily be done on site) of the tubular elements 16 and/or 18, with equal regulation fields, without the need to keep special components in stock, or to carry out on site inappropriate cutting operations of existing components.
- the height adjustment mechanism of the column is completely hidden, therefore the column has a pleasant appearance and can be used when laying transparent flooring.
- the vertical load is supported by the screw system, bolt and internal tubular element, while the side or radial load is supported by two internal and external telescopic tubular elements and guided between themselves.
- the column support is made of seven members, which can be packed and assembled in different ways, all at very low costs.
- the seven members can be packed loose, as illustrated in Figure 1, and assembled one at a time.
- a package can be prepared, as illustrated in Figure 5, where the screw 22, the female screw 23 and the washer 30 are assembled in a subgroup, which are in turn assembled to the other loose members.
- the column may be packaged with the base 11 and with the internal sleeve 16 loose, together with two subgroups made up of: a first subgroup of screw 22, female screw 23 and washer 30 and a second subgroup made up of the head and the external tubular element 18, as illustrated in Figure 6.
- the column may be packed with the base 11 and the internal tubular element 16 loose, and with all the other components mounted into a single subgroup, as illustrated in Figure 7.

Abstract
Description
- The present invention relates to some improvement features made to the support columns used to lay down superelevated modular flooring.
- As men skilled in the art well know, the adoption of superelevated modular flooring, in any kind of construction, is rapidly expanding.
- In fact, in a construction built adopting superelevated modular flooring, the installation of the entire plant engineering network, besides being simple, rapid and rational, also has the advantage of allowing for future intervention, be it maintenance or according to contingent requirements, by simply raising one or more panels, with the objective of gaining access to the system underneath, for example to create a new job-station, or other.
- Once all of the connections required have been made, it is only necessary to reposition the panel, or the panels, removed to restore the flooring as it was originally, without having carried out any complicated or costly destructive intervention.
- The superelevated modular flooring is made up of a structure which can be composed of single height adjustable columns, or (more frequently) columns that are interconnected by cross-beams, upon which the panels are supported and possibly fixed.
- Superelevated modular flooring of the type known is described, for example, in US Patents 4.279.109, 4.676.036, 4.685.258, 4.719.727, 4.850.162, 5.088.251, 5.412.914.
- In a superelevated modular flooring, of the type briefly described above, the support column of the panels is extremely important and it should be made in such a way as to satisfy all of the following main requirements.
- The support column should first of all be height adjustable, in a simple, fast and convenient manner for the staff in charge of laying the flooring, in order to allow for perfect reciprocal levelling of the panels.
- The height adjustability of the support column should also be possible once the floor has been laid, removing the smallest number of panels possible, preferably just one.
- Beyond the maximum adjustability field (excursion between the minimum and maximum heights), the structure of the column should allow for the creation of columns of different heights, according to requirements, without having the precise need of having available more special components, especially produced for the objective, with the obvious inconveniences that may arise.
- In addition, the support column should have a structure which may be produced at a low cost, with the possibility of assembly starting from all of the loose components (separate) and starting from the different undergroups which may be assembled reciprocally.
- Then, the column structure should be capable of supporting heavy loads even though of a small size (diameter).
- Furthermore, the height of the support column should be finely adjusted (micrometric regulation) and slackening means should be provided for to prevent possible variations in the predefined adjustment, due to the vibrations that the floor is submitted to, originating from the various levels of strength.
- Finally, the regulation mechanism of the column should be completely hidden, in order to create a column with the most pleasant appearance possible, especially for flooring made with transparent materials, such as glass for example.
- Support columns like the ones that are well known are not capable of adequately satisfying all of the above mentioned requirements.
- The general object of the present invention is that of creating a height adjustable support column, for superelevated modular flooring, capable of satisfying all of the above mentioned requirements.
- This object is achieved by a column with the features indicated in the main claim attached hereto and in the dependent claims.
- The structural and functional features of the invention and the advantages thereof with regards to the known technique can be clearly understood from an examination of the following description, referring to the drawings attached, which illustrate an example of embodiment of the invention itself. In the drawings:

- Figure 4 is a view, as Figure 3, illustrating the column in a raised state according to the regulation allowed for;
- Figures 5, 6 and 7 are perspective views illustrating three assembling possibilities of the column according to the invention, starting from various sub-groups;
- Figure 8 is a perspective view illustrating the possibility of height adjustability from the top of the column according to the invention, by removing only one of the panels (generally four), which rest onto the column itself;

- Figure 15 is an enlarged section view of a detail of Figure 14; and
- Figure 16 is a view in plant from the top of the support of Figure 14.
- With reference to the drawings, the support column for superelevated modular flooring according to the invention is indicated in its whole with 10.
-
Column 10 is structurally made up of asupport base 11 and atop support 12 aimed at receiving, directly thepanels 13 of the floor, or a system ofcross beams 14 upon which thesepanels 13 rest (Figure 8). - The
base 11 and thetop support 12 are interconnected by means of telescopic support 15 (Figures 13, 14) containing the height adjustable mechanism (hidden) of thecolumn 10. - More precisely, such
telescopic support 15 includes a first internaltubular element 16 trigged, for example for interference, on a male piercedattachment 17 which extends centrally from thebase 11. In this way, thebase 11 and the internaltubular element 16 are firmly fixed between themselves. - Upon the first internal tubular element 16 a second external
tubular element 18 is mounted and translates, which is also fixed to thesupport 12. In this way, thesupport 12 is structurally formed by aglass 19 upon which the externaltubular element 18 is fitted with interference. The bottom of thisglass 19 has ahole 20, whilenumerous spokes 21 appear from its top edge (in the example illustrated, there are four), aimed at receiving thepanels 13 and the cross beams 14 (Figure 8). - The height of the
telescopic support 15, and therefore of thecolumn 10, can be adjusted by a micrometric adjustment mechanism which is generally accessible from the top, and is completely contained within thetelescopic support 15 itself. - Such micrometric adjustment mechanism is a
screw mechanism 22 and afemale screw 23, wherein thefemale screw 23 is blocked with interference at the top of the internaltubular element 16, while thescrew 22 is fitted, at the highest extremity, with amanoeuvre head 24, which is easily adjoined against the piercedbase 25 of theglass 19. Furthermore, thehead 24 of thescrew 22 has aseat 26, for example hexagonal, which can be accessed through thehole 20 of theglass 19, for a manoeuvre tool 27 (Figure 8). - As clearly illustrated in Figures 10, 11 the
female screw 23 presents, for example,lines 28 or similar (conicity) for stable coupling with interference, at the top of the internaltubular element 16. In this way, thefemale screw 23 is inserted using pressure into thetubular element 16 until it reaches one of itscircumferential undercuts 29 against the edge of thetubular element 16 itself. - The height adjustable mechanism of the
column 10 according to the invention includes a washer which is resiliently pliable 30 (Figures 1, 12, 13, fitted onto thescrew stem 22 and abutting against the lower face of thehead 24. - In this way, the
screw stem 22 has an unthreaded restraint area 33 (Figure 9) with gripping ridges (or equivalent). - As is clearly illustrated in Figures 1, 12, 13,
such washer 30 has a series of interspaced externalcircumferential teeth 31, slightly bent (just a few degrees) downwards, and a series ofinternal teeth 32, intercalated toteeth 31, bent downwards, by approximately 90°, in order to identify a stop neck which puts pressure on the stem of thescrew 22, opportunely predisposed with the above mentionedarea 33 of fixing. - However, the
external teeth 31 act using a friction movement over the internal surface area of the externaltubular element 18, as illustrated in the Figures, in particular in Figure 9. - Figures 14-16 illustrate another possible realization of the support column of the present invention, where similar elements are indicated with the same reference numbers.
- In this example the
washer 30 is not present and asupport 112 is provided for, of an almost flat shape, welded to the externaltubular element 18. Thehole 20 provides for fourstalks 40 placed at 90° from one another, aimed at abutting against aborder 41 made above thehead 24 of thescrew 22 and engaging itself with it. Thehead 24, furthermore, has acentral protuberance 42 which fixes itself between thehole 20 and thehousing 26 is left empty for themaneouvre tool 27. Thestalks 40, of any number whatsoever, engage themselves with thehead 24 of thescrew 22 and prevent unscrewing even in this case. - The operation of the support column according to the invention is clear as described above with reference to the drawings, and briefly is the following.
- The
support columns 10 of the tubular flooring are placed on the concrete slab of the building, and possibly fixed to thebase 11, and possibly also interconnected between themselves, using thecross beams 14, as illustrated in Figure 9. - The height adjustment of the
column 10 is conveniently carried out from above, without any problems whatsoever for the operator, using the tool 27 (or any other tool suitable for the task, introduced - through the pierced bottom of the glass 19 - in thehousing 26 of thehead 24 of the screw 22), in the screwing or unscrewing direction, as indicated byarrows 33 of Figure 8, depending if the height of thecolumn 10 is to be increased or reduced. We must point out that such an operation may be carried out automatically through the use of motorized systems that are controlled by level sensors. - Thanks to the action of the
anti-unscrewing washer 30, acting in a positive manner between thescrew 22 and the externaltubular element 18, the prefixed height of thecolumn 10 is guaranteed throughout time, even in the presence of relevant stresses transmitted by the overhanging flooring. - Characteristically, in case of need, the
column support 10 can be reached simply by removing just one of thepanels 13 which puts pressure on it, as illustrated in Figure 8, through the introduction from above oftool 27 which can be inserted into thehexagonal head 26 of thehead 24 of thescrew 22 passing easily through thehole 20 at the bottom of theglass 19. - Another important advantage of the support column according to the invention is that columns of different heights are achieved by simply modifying the length (an operation that can easily be done on site) of the
tubular elements 16 and/or 18, with equal regulation fields, without the need to keep special components in stock, or to carry out on site inappropriate cutting operations of existing components. - As can be clearly seen from the drawings, the height adjustment mechanism of the column is completely hidden, therefore the column has a pleasant appearance and can be used when laying transparent flooring.
- A column that is produced according to the regulations of this invention, despite the relatively small diameter of the
telescopic support 15, is capable of bearing extremely heavy weights, as the only function of thescrew 22 is that of contrasting the compression loads, while the flexural loads are contrasted by thetelescopic support 15. - More precisely, the vertical load is supported by the screw system, bolt and internal tubular element, while the side or radial load is supported by two internal and external telescopic tubular elements and guided between themselves.
- According to the invention the column support is made of seven members, which can be packed and assembled in different ways, all at very low costs.
- The seven members can be packed loose, as illustrated in Figure 1, and assembled one at a time.
- On the other hand a package can be prepared, as illustrated in Figure 5, where the
screw 22, thefemale screw 23 and thewasher 30 are assembled in a subgroup, which are in turn assembled to the other loose members. Or, according to the invention the column may be packaged with thebase 11 and with theinternal sleeve 16 loose, together with two subgroups made up of: a first subgroup ofscrew 22,female screw 23 andwasher 30 and a second subgroup made up of the head and the externaltubular element 18, as illustrated in Figure 6. - Finally, according to the invention the column may be packed with the
base 11 and the internaltubular element 16 loose, and with all the other components mounted into a single subgroup, as illustrated in Figure 7. - The objective mentioned in the preamble of the description is therefore achieved.
- The scope of protection of the invention is defined in the following claims.
