DESCRIPTION:
BRIEF SUMMARY
The invention relates to flooring systems with service trunking facilities.
So-called suspended floors using pillars readily afford maximum flexibility in arrangement of service feeds, including electrical cable of various classes, between support pillars at corners of rectangular floor panels. Other "added-on" flooring systems use corrugated sheet material between the base or substrate to be floored and the actual floor sheeting or boarding to be installed, and there is less flexibility in arrangement of service feeds, albeit with greater potential discipline in the sense that individual corrugation channels can be dedicated to specific types or classes of service, which are thus kept segregated by sides of the corrugation channels. Manifestly, however, such rigid discipline presents problems for running services transversely of their dedicated channel or channels to outlets or even other similarly dedicated channels, whether from loss of segregation discipline in passage-ways formed transversely to the corrugated sheet, or from difficulty of "fishing" for electrical cable if such segregation is maintained by transverse ducting such as using one or more dividers and upwardly-closed channel members at base/substrate level to and between apertures at corresponding levels in the dividers (see British patent specification no. 2121450A), or from difficulty of affording full "metal-shell" type isolation for electrical power feed services.
Objects of this invention include satisfying one or more of improving upon added-on flooring systems and improving upon the system of British patent specification no. 2121450A and affording viable alternative(s) thereto.
According to one aspect of this invention, a flooring system to go onto an existing base or substrate avoids use of corrugated sheet to support the flooring panels intended to be added on, such flooring system comprising discrete elongate flooring panel supports to extend in parallel spaced relation from sides of transversely extending segregation ducting, the supports and the ducting affording mutual communicating accommodation for service feeds in and between their respective directions.
Such a system is suited to installation using its transverse segregation ducting for reference purposes, i.e. installing the latter at suitable spaced intervals so as then to be suitably interconnected via said elongate flooring panel supports, rather than using spaced corrugated sheeting as reference for installing the segregation ducting. There is, of course, also self-evident scope for saving material relative to systems using corrugated sheet, and at least some of the elongate supports may serve simply as dividers rather than service passages in themselves.
In one preferred embodiment of said one aspect of this invention, at least some elongate flooring panel supports comprise upwardly open members of channel section and top closures therefor to provide fully isolated feedways, say of the aforementioned "metal-shell" type for electrical power outfeeds. Spacings between parallel-installed such elements can serve for other services, i.e. segregated from electrical power. Moreover, other elongate flooring panel supports could, if desired, divide such spacings to further segregate such other services, and may suitably comprise downwardly open elements of channel section, conveniently or as may be desired, narrower than those first-mentioned. We do not, of course, rule out the possibility that such downwardly open elements are themselves traversed by service feeds.
Turning to another aspect of this invention, segregation ducting is proposed having spaced parallel sides, at least one medial divider parallel to the sides, and trough- or tray-like elements extending selectively between aperturing of the sides and divider(s) at upper parts thereof, thereby leaving room below for passage of segregated service feeds with appropriate access therefor up into said trough- or tray-like elements.
Suitable sides and divider(s) are each plates having slotting from their upper edges to mat
