The second formation 160 may be provided at the upper end 102 of the second member 100. Alternatively, the second formation 160 may be provided on the sidewall 122 of the second member 100.

As mentioned above, the device 200 includes a second device member 205. In the present embodiment the second device member 205 includes a second device member generally upwardly extending part 220 defined by a sidewall 222 which extends away from the first device member 202 in a generally perpendicular direction to a plane in which the first device member 202 lies. The second device member generally upwardly extending part includes a recess 224 within which a portion of a temporary flooring or structure may be received. The sidewall 222 may include apertures 226 which extend in a direction which is generally orthogonal to the side wall 222 and parallel to the plane in which the first device member 202 lies. The apertures 226 are configured to receive fastener devices to secure the temporary flooring or structure to the device 200, and therefore the apparatus 1. In the present embodiment four such apertures 226 are provided arrange in pairs generally opposite each other to receive fastener devices.

The device 200 may be configured to permit a fastener device 210 to fasten the first device member 202 to the second member 100. In particular, the device 200 may include at least one aperture 210 configured to receive at least one generally elongate member and the second member 100 may include at least one aperture 170 configured to receive at least one generally elongate member to couple the device 200 to the second member 100.

A further device 400 may also be provided, as shown in the present embodiment. The device 400 is substantially the same as the device 200. Therefore, only the differences therebetween will be described.

Device 400 is positioned, in use, on the sidewall 122 of the second member 100 of the apparatus 1. The device 400 includes a first formation for cooperating with a second formation 180 provided on the sidewall 122 of the second member 100 of the apparatus 1 to permit a coupling therebetween. The device 400 includes a second device member 405 which may be configured, in use, to receive cross-members for temporary flooring. The second device member 405 may include an outwardly extending part 408. The outwardly extending part 408 may extend away from the first device member 402. In particular, the outwardly extending part 408 may extend in a direction which is generally orthogonal to a plane in which the first device member 402 lies. First and second protrusions 406, 407 are provided on the outwardly extending part 408. The protrusions 406, 407 are both provided on an upwardly facing surface of the outwardly extending part 408. The protrusions 406, 407 may be configured to pass through apertures, or recesses, in temporary flooring, or a cross-member for temporary flooring.

The second formation 180 may include first and second channels 181, 182 which in use receive the first formation which may include first and second protrusions. The first and second channels 181, 182 may taper towards each other as they extend from the upper end 102 towards the lower end 101. The first and second protrusions may also taper towards each other from a first side to second side.

The apparatus 1 may be used as part of a temporary flooring or temporary structure (not shown). The temporary flooring or structure may include one or more of the apparatus 1 or may be supported entirely by a plurality of apparatus 1.

Operation of the apparatus 1 will now be described.

Firstly, the first member 10, or the first portion 12 of the first member 10, is placed on the surface on which the temporary flooring or structure is to be erected. The first member 10 is secured to the surface by passing securing devices through the apertures 22. Optionally, when present, the second portion 14 including the pivot member 30 is then positioned on top of the first portion 12. Bolts are provided on the underneath of the first member 10 which pass through the apertures 28 in the first and second portions 12, 14.

The second member 100 is then placed onto the first member 10. In particular the second member 100 is slid over the upwardly extending elongate member 24. The first height adjustment member 108 then rests on a top of the upwardly extending elongate member 24.

The second member 100, or the second portion 14 of the first member 10, is then oriented using the pivot member 30. The second member 100, or the second portion 14 of the first member 10, is pivoted relative to the first member 10, or the first portion 12 of the first member 10, about first and second axes to a desired position. The desired position may be a position in which a top, or upper end 102, of the second member 100 lies in a generally horizontal plane. This may be achieved through the use of a tool for measuring the orientation of the upper end 102, e.g. a spirit level or level laser tool.

The first and second portions 12, 14 of the first member 10, and thus the first and second members 10, 100 are then fixed in the desired position. This is achieved by fastening nuts 32 onto the bolts which extend through the apertures 28. The nuts 32 are tightened onto the bolts so as to engage with respective portions of the upwardly facing surface 34 of the second portion 14 to inhibit pivotal movement of the second portion 14 therepast. The provision of multiple nuts and bolts assists in fixing the second portion 14 in position relative to the first portion 12. For example, if the planar formation 20 of the second portion 14 attempts to move downwardly from its fixed position at a first nut and bolt fastening this would require the planar formation 20 to move upwardly at a second nut and bolt fastening. Since the nut and bolt fastening at the second position will not inhibit movement of the planar formation 20 past the nut it is not possible for the planar formation 20 to move downwardly at the first nut and bolt fastening. Therefore, the first and second portions 12, 14 are fixed in position. This position may be an inclined position with respect to the floor surface.

The device 400 is then slid into the formation 180 on the sidewall 122 of the second member 100 to permit flooring to be supported thereon. The device 400 is held in position by virtue of gravity.

A height of the apparatus 1 and device 400 is then altered to a desired height (h). The height of the apparatus 1 is adjusted using a tool on a head of the bolt 110. Rotation of the bolt 110 causes a linear movement of the second member 100 relative to the first member 10. This is because the first height adjustment member 108 is inhibited from rotation within the space 104 defined by the second member 100 and because the first height adjustment member 108 lies on the top of the upwardly extending elongate member 24.

Once the apparatus 1 has been adjusted to a desired height (h), the elongate members 42, provided as bolts onto which nuts are threaded, are passed through apertures in the first and second members 38, 124 and then tightened to fasten the second member 100 at the desired height (h), relative to the first member 10.

Device 200 is then attached to the top of the second member 100. This is achieved by sliding the device 200 onto the top of the second member 100 such that grooves of the first device member 202 receive protrusions 160 of the top of the second member 100. The device 200 may then be secured in position by passing a fastening device through apertures 170, 210.

The steps above are then repeated for each of the apparatus 1 which are to be used in support the flooring and/or temporary structure. For example, the apparatus 1 may be arranged in a matrix configuration with each of the apparatus 1 being equi-spaced with respect to one another over a desired floor area the flooring is required to cover.

Bracing members of respective apparatus are then connected together by tensioning means such as ropes or other suitable means to reinforce the temporary flooring or structure once erected. In particular the tensioning means are connected at one end to the brace member 50, which is positioned towards a lower end of a first apparatus 1, and, connected at another end, to the brace member 150 of a second apparatus 1 which is positioned towards an upper end of the second apparatus 1. This provides for structural support against any sideward forces that may be experienced by the apparatus 1 that could otherwise cause the apparatus 1 to topple sidewards, for example.

Once all of the apparatus 1 are sufficiently secured and braced, the temporary flooring is laid onto the apparatus 1. In particular, cross-members for the flooring are laid onto the device 400. In particular, the apparatus 1 are spaced at distances that permit the protrusions 406, 407 of the outwardly extending part 408 to pass through corresponding apertures or be received in recesses in the cross-members for the temporary flooring to permit the cross-members to be secured relative to the apparatus 1. Flooring is then laid on top of the cross members.

Once the flooring has been laid the temporary structure is erected. This includes component parts of the temporary structure, such as column members for supporting a roof of the temporary structure, being inserted intorespective recesses 224 of the devices 200. This is completed for all of the necessary component parts of the temporary structure to enable erection of the temporary structure. Following this the components of the temporary structure are then fastened to the device 200 by passing fastening devices through respective apertures of the component parts and through apertures 226 in the sidewall 222 of the device 200.

In embodiments there may be no devices used and the temporary flooring or structure may be attached directly to the apparatus 1, e.g. the second member 100. The height (h) is used to refer to the distance between the respective position at which the temporary flooring or structure is attached to the apparatus 1 and the floor surface on which the apparatus 1 rests. The temporary flooring or structure may be attached at different positions or portions of the apparatus 1.

In embodiments the apparatus 1, devices 200, 400, extension 300 and system may be fabricated from sheet metal. In particular, the apparatus 1, devices 200, 400, extension 300 and system may be fabricated from plate steel. However, it should be appreciated that other fabrication methods and other materials could be used to form the apparatus 1, devices 200, 400, extension 300 and system without departing from the scope of the present invention provided that the materials used and/or structures fabricated are capable of supporting the load of the temporary flooring and/or temporary structure.

Embodiments according to aspects of the present invention provide advantages over the prior art. For example, the height adjustment device forms a fixed component of the apparatus which means that one can conveniently install the apparatus as the apparatus is self-contained. Also, in embodiments, the configuration of the first and second members provides for an elegant design that is more easily manufactured compared to the prior art and/or the fastening devices for the members are readily available rather than the bespoke fastening devices required by the prior art. In embodiments, the configuration of the first and second members, and the height adjustment device, permits for a continuous range of heights to be achieved unlike the prior art which often only permits a discrete height adjustments.

In embodiments, the apparatus provides for levelling of the temporary flooring or structure about one or more pivot axes which may be important for applications where the floor surface is not level or homogenous.

In embodiments, an advantageous system is provided that permits one to connect multiple, different, component parts of a temporary structure or flooring through the use of devices that are adapted for this purposes, i.e. the devices are adaptor devices that transform the apparatus for multiple purposes. Such a system is thus multi-functional and flexible over the prior art.

In embodiments, the apparatus is relatively straightforward to install with reductions in installation, skill and effort required compared to the prior art.
