Description

AN ACCESS FLOORING SYSTEM
Introduction
This invention relates to an access flooring system of the type comprising a plurality of floor panels and a plurality of support pedestals for supporting the floor panels.
The pedestals are distributed over a subfloor, such as a floor of a multistorey building, and the pedestals are arranged to support the floor panels such that floor panels may be individually removed to gain access to the chamber below the floor panels. When assembled, the floor panels provide a relatively flat and strong floor to support office personnel, furniture and the like.
There is a potential problem of floor panels contacting adjacent floor panels and whilst being walked upon causing a noise to be created in the form of a metallic squeak.
: ** In one current approach a spacer may be placed between the top side edges of adjacent floor panels. However, this has the problems of affecting aesthetic appearance and additionally of being difficult to install on-site. I. * *.*
* There is therefore a need for an improved access flooring system which addresses at least some of these problems.
*S..*.

Detailed Description
Referring to the drawings, and initially to Figs. I to 4 thereof, there are illustrated various elements of an access flooring system according to the invention. The system comprises a plurality comprising a plurality of floor panels 10 and a plurality of support pedestals for supporting the floor panels 10. Each pedestal has a pedestal cap 1, as illustrated in the drawings, mounted to the pedestal. A gap is provided between adjacent panels 10.
The cap 1 has at least one, and in this case four equi-spaced apart separators 2. The separators 2 comprise a base portion 3 and a top separator portion 4. The separators 2 are connected to the pedestal cap I at the base portion 3 and extend upwardly from the pedestal cap 1. In lateral cross-section, the separators 2 taper inwardly from the base portion 3 to the top separator portion 4 thereof. The top portion 4 of the separator 2 typically has a width of between 30 and 50 per cent of the width of the base 3 thereof. The angle of the taper is essentially determined by the angle of the sides of the panels 10 being separated. The form of the separator 2 is such as to avoid contact between the panels 10 and the separator 2 at the base 3 and to bias the contact between them to the upper edge or top portion 4 of the separator 2, as illustrated in Fig. 1. * ** * I I *1I*
In this case, the separators 2 also taper inwardly from the base 3 to the top 4 in longitudinal cross-section. The separators 2 extend radially relative to the centre of thepedestalcapl.
I I..
The pedestal cap 1 comprises a lower face 7, a top face 8 and a raised platform portion 9. As shown in the drawings in this case, the raised platform portion 9 has a cross-form. The pedestal cap 1 has an increased thickness at the raised platform portion 9. This is determined by the construction of the panel 10 and accommodates the rebate used on the underside of the panel 10 whilst ensuring the load transfer point is on the edge of the panel 10.
In this case, the top of the separator 2 comprises a groove 5 provided between two ridge portions 6 (Fig. 4). The groove 5 and ridge portions 6 extend the length of the top of the separator 2. The arrangement of the groove 5 between the ridges 6 permits some deformation of the top portion 4 of the separator 2 on contacting the side walls of adjacent panels 10. This arrangement facilitates lateral compliance in the system but ensures that the gap between the adjacent panels 10 is maintained. Under the forces exerted by adjacent panels 10 on the top portion 4 of the separator 2, the top of the separator 2 is compressed and the ridge portions 6 moved towards each other.
The groove 5 has a substantially u-shaped or v-shaped form and is located at the centre of the top portion 4 of the separator 2. The groove 5 has a width of between and 70 per cent of the width of the top of the separator 2 to provide the required lateral compliance.
The separator 2 on engaging the side walls of adjacent panels 10 acts to control the gap between adjacent panels 10 so as to prevent contact between adjacent panels 10.
The separator 2 is robust and of a material which has sufficient mechanical strength to maintain a gap between adjacent panels 10. Taking account of the form of the side walls of the panel 10, the separator 2 is formed, so as to provide adequate * ** positive contact between the top portion 4 and the side walls, and having sufficient mechanical strength to maintain that gap. S...
The panel 10, in this case, comprises a central core or substrate 13 which may be of chipboard or the like, and an envelope comprising a top 15 and a base 14 enclosing the core 13. Side walls 17 of the panel 10 are typically inclined at an angle of *: * between 3 and 10 degrees, preferably between 5 and 7 degrees. As shown in Fig. 1, the side walls 17 are inclined outwardly from the base 14 to the top 15 of the panel 10.
In practice, within the limits of the panel production process, there is often tolerance in the geometry of the panel 10, with the tolerance being greatest at the base 14 and the lower portions of the side walls 17. Typically in production, the dimensions which are most carefully controlled are those of the top IS of the panel JO since this traditionally sets the grid and is visible when the floor is laid. The dimensions of the base 14 are often less stringently controlled in both dimension and position, making the base 14 a poor surface from which to datum.
As shown in the drawings, the separator 2 extends upwardly from the pedestal cap 1 and is configured to be positioned between adjacent panels 10 so that it contacts the side walls 17 of the panels 10 near to the top 15 thereof and acts to control the gap between the panels 10.
The separator 2 of the invention has a height of between 7 and 20 times the thickness of the pedestal cap 1, preferably between 10 and 15 times the thickness of the pedestal cap 1.
For a panel 10 having a depth D, the separator 2 has a height> D/2, and preferably = 3/4D.
It has been found that by providing a separator 2 having a relatively high vertical I...
* *** extent, relative to the depth of the panel 10, the effectiveness of the separator 2 is increased since it is designed to contact the panels 10 near the top portion 4 thereof where the tolerance in the geometry of the side walls 17 of the panel 10 is reduced.
* * This ensures that an improved contact is provided between the separator 2 and the adjacent panels 10.
Example
Referring to Figs. 5 (a), 5(b) and 5(c), a pedestal cap 1 according to the invention is shown.
In this case the separator 2 have an overall height of 23mm when measured from the face 8 of the cap I and 22mm from the platform portion 9 of the pedestal cap 1.
The pedestal cap I has an increased thickness at the raised platform portion 9, for example for a pedestal having a thickness of 1.5 mm, the thickness at the platform portion 9 may be 2.3 to 2.7mm, preferably 2.5mm.
The separator 2 in this case has a height 15 times the thickness of the pedestal cap I and substantially 9 times the thickness of the pedestal cap I at the platform portion 9 thereof.
Taking the lateral cross-section of the separator 2. At the base thereof the separator 2 has a width of 5mm and tapers inwardly to a width of 2.05mm at the top thereof.
Overall the width decreases by 2.95mm from the base to the top, i.e. the width at the top is 41% of the width at the base. Taking the decrease in width of the separator 2 as a percentage of the height of the separator 2, the overall taper from base to top is between 12 and 14 per cent.
Taking the longitudinal cross-section of the separator 2. At the base thereof the p...
separator 2 has a length of 18mm which tapers inwardly to a length of 16 mm at the top thereof, an overall decrease in length by 2mm, i.e. the length at the top is 88% of thelengthatthebase. .4
As noted above the width of the top portion of the separator 2 is 2.05mm, and in this case the groove 5 has a width of 1.05mm and a depth of 1.5mm. e.
In this case the separator 2 has a height of 23mm which is suitable for use with a panel 10 having a depth of 30 to 33mm.
The system of the invention provides means for engagement of adjacent panels 10 with the pedestal separator 2 which enables accurate control of the gap between adjacent panels 10 and avoids the problem of adjacent panels 10 touching. This minimises the risk of squeaking or grinding noises at the joints between panels 10 when personnel walk over the panels 10.
Referring to Figs. 6 to 10 there is illustrated another pedestal cap 30 according to the invention, which is similar to the pedestal cap I of Figs. I to 4, and similar elements in Figs. 6 to 10 are assigned the same reference numerals.
In this case no groove is provided at the top of the separator 2, as illustrated in Fig. 7.
A metallic plate 31 is coupled to the pedestal cap I on the upper side of the raised platform portion 9 (Fig. 6). The plate 31 comprises two securment fingers 32 to couple the plate 31 to the pedestal cap 1. Each finger 32 extends through an opening 33 in the pedestal cap I and extends along the underside 7 of the pedestal cap I (Fig. 9). In this manner the fingers 32 act as hooks to couple the plate 31 to the pedestal cap 1.
The plate 31 acts as an electrical conductor. 0.Sa * .
In Fig. 11 there is illustrated another pedestal cap 40 according to the invention, which is similar to the pedestal cap 30 of Figs. 6 to 10, and similar elements in Fig. 11 are assigned the same reference numerals.
In this case the separator 41 has a substantially dumb-bell shape in plan view at the top portion 42. The top portion 42 defines a panel engaging portion 43 at each end of the top portion 42, and a non-engaging portion 44 at the centre of the top portion 42.
In use, the engaging portions 43 engage the adjacent floor panels 10. The non- engaging portion 44 does not engage the floor panels 10. Because the non- engaging portion 44 does not engage the floor panels 10, this facilitates local deformation of the panels 10. In this manner the pedestal cap 40 facilitates lateral compliance while maintaining the gap between adjacent floor panels 10.
The invention is not limited to the embodiments hereinbefore described, with reference to the accompanying drawings, which may be varied in construction and detail.
