Abstract

This comprises an adjustable head 14 mounted on a threaded spigot 12 in turn secured to a base boss 13. Base bosses 13 may be threaded into base channels 18 in grid formation on a solid base floor. The head 14 may pivot at 24 to allow the formation of sloping ramps. <IMAGE>

Description

SPECIFICATION Support means for raised floors The present invention concerns raised floors adapted to provide a series of hollow chambers or a network of channels therebelow.

With the advent of modern technology it has been found necessary to provide channels belowthe finished floorfor pipework, electrical cables etc. which latter can be easily accessibleforthe repair or renewal thereof.

Therefore it has also been found necessary to provide a means for retaining the finished floor at a fixed distance above the solid base formation level.

Modern office buildings have solid floors made of reinforced concrete and the cost offinishing such a floor accurately with a screed becomes high due to the necessity of using skilled labour.

An object ofthe present invention is to provide a plurality of individually adjustable support means for the finished floor so that the level of the base is not critical.

According to the present invention a support means for a raised floor comprises a vertically adjustable head connected to a spigot secured to a base boss.

Such support means may be arranged at regular intervals to form a grid and, to ensure that they remain in position on a solid base, each base boss isthreaded into a base channel secured to the solid base. For easy adjustmentthe spigot is screwthreaded and the head member is held in the correct position by an adjusting nut. The head is preferably of such construction that a main channel and a cross channel can be snap fixed thereto to provide a complete supporting grid for a boardfloorfinish.

The invention will now be described further, byway of example, with reference to the accompanying drawings, in which: Fig. 1 is an elevation of a support means constructed in accordance with the invention; Fig 2 is afragmentaryside elevation oftheflooring boards positioned over the main floor runners mounted on the support means; Fig. 3 is a fragmentary perspective view ofthe support means located in a base channel and supporting a main runner; and Fig. 4 is an elevation of a support means incorporating flanges for use when the system has to form sloping ramps.

Asupport means 11 shown in Fig. 1 comprises threaded spigot 12 secured on a circular base member 13.Asupport head 14is bored in its centre 15 (Fig. 3) to fit over the top of the spigot 12 and is adjustably secured in position by a nut 16. The support head 14 has four upstanding arms 1 4a each ofwhich has an upper central groove 14b. In practice the support head 14with grooves 14b, is stamped out of a metal plate and the arms 1 4a are subsequentlyfolded upwardly by any suitable means. To ensure the correct position ing of the support means 11 on a solid floor base 17, channel members 18 are secured by any suitable means to this base 17 in grid formation.

In use, each circular base member 13 is threaded into the channels 18 at pre-arranged positions, suitably at 600 mm centres. Main head channels 19 are snap fitted over opposite arms 1 4b whilst cross channels (not shown) are snap fitted overthe other two opposite arms 14b. A board floorfinish 20 is then laid over the main and cross channels. It can be seen that a void 21 (Fig. 2) is left below the support channels above the floor base 17; suitablythis void hasa minimumdepth of25 mm.

Fig. 4 shows an alternative embodiment incorporating two pairs of pivotal flanges. One pa ir of flanges is formed by an upper, generally U-shaped, member comprising two depending parallel arms and a base 22a, and a similar member23 comprising two upstanding parallel arms and a base 23a. The base 22a is secured to the base ofthe support head 14whilstthe base 23a, having a bore therethrough rests on the nut 16. Each pair of juxtaposed arms of the members 22 and 23 are pivotably connected at 24to each other.

The provision of these pivotal members 22 and 23 permits the head to assume a sloping position when the head channel 19 is placedthereoveratan angleto the horizontal.

CLAIMS (filed on 22 Feb.83) 1. Asupport means for a raised floor comprising a vertically adjustable head connected to a spigot secured to a base boss.

2. Asupport means as claimed in claim 1, in which a plurality of support means are arranged at regular intervals(on a base) to form a grid.

3. Asupport means as claimed in claim 1 or2, in which each base boss is threaded into a base channel secured to a solid base floor.

4. A support means as claimed in claim 1,20r3, in which the spigot is screwthreaded and the head member is held in position thereon by an adjusting nut.

5. Asupport means as claimed in claim 4, in which a pair of parallel flanges depend from the adjustable head and are pivotally mounted on a pair of parallel flanges upstanding from the adjusting nut.

6. A support means as claimed in any preceding claim, in which the head is formed with two upstanding pairs of arms arranged at right angles to one another.

7. A support means constructed and arranged to operate substantially as herein described with referenceto and as illustrated in Figs. 1,2 and 3 of the accompanying drawings.

8. A support means constructed and arranged to operate substantially as herein described with referenceto and as illustrated in Fig. 4 of the accompanying drawings.
