Description
<Desc/Clms Page number 1>
Agents Ref : P15666GB-NHF/SJP/mm IMPROVEMENTS IN OR RELATING TO SCAFFOLDING DECKS
THE PRESENT INVENTION relates to a scaffolding deck and a method of assembling a scaffolding deck.
Scaffolding decks are well-known and are widely used to provide a generally horizontal working surface extending between a pair of spaced-apart horizontal scaffold members (ledgers) forming part of a scaffolding structure.
Typically, scaffolding decks are generally elongate in configuration and carry at each end, a pair of hooks or the like to releasably engage a ledger.
One known type of scaffolding deck comprises three major components, namely a pair of elongate beams (each carrying a hook at each end) and an elongate, generally planar deck plate. The two beams are arranged so as to be substantially parallel with one another, with the deck plate extending therebetween, the deck plate being secured along its longitudinal edges to a respective beam by way of a plurality of rivets.
The above-mentioned type of scaffolding deck has been found to suffer from certain disadvantages. For example, initial assembly of this type of scaffolding deck is complicated and time consuming by virtue of the need properly to install each of said plurality of rivets along the length of the deck plate. Thereafter, it is inconvenient to disassemble the scaffolding deck, for example for storage or transportation. Removal of rivets is typically done by
<Desc/Clms Page number 2>
drilling out each rivet which, in the case of the prior art scaffolding decks described above, involves many manual drilling steps with the effect that disassembly of the above-mentioned prior art scaffolding decks can take considerable time.
It is therefore an object of the present invention to provide an improved scaffolding deck and an improved method of assembling a scaffolding deck.
According to a first aspect of the present invention, there is provided a scaffolding deck comprising a pair of elongate beams, a deck plate, and engaging means configured to slidingly engage each beam with the deck plate along a respective edge of the deck plate.
Preferably, the engaging means comprises a respective beam-channel formed along at least part of the length of each beam, each beam-channel being configured to slidingly receive part of the deck plate.
Advantageously, the engaging means comprises a respective beamchannel formed along at least part of the length of each beam, each beamchannel being configured to slidingly receive part of the deck plate.
Conveniently, each deck-channel is configured to slidingly engage a respective beam-channel.
Preferably, the deck-channels and the beam-channels are configured to be secured to one another by a mechanical deformation.
<Desc/Clms Page number 3>
Advantageously, each beam-channel is defined between a flange projecting outwardly from the beam and an inwardly turned lip carried by the outermost edge of the flange.
Conveniently, each said flange projects outwardly from a substantially planar side wall of the beam, and wherein the edge of the lip carried by each flange is spaced from the respective side wall to define therebetween an opening to the channel.
Preferably, each deck-channel is defined between one surface of the deck plate and an inwardly turned lip carried by the respective edge of the deck plate.
Advantageously, each beam comprises an aluminium extrusion.
Preferably, the deck plate is steel.
Advantageously, each beam has a substantially planar upper surface which lies substantially co-planar with a substantially planar upper surface of the deck plate when the deck plate is engaged with the beams.
According to a second aspect of the present invention, there is provided a pair of elongate beams and a deck plate; and slidingly engaging each beam with the deck plate along a respective edge of the deck plate.
Preferably, each beam is provided with a respective beam-channel formed along at least part of its length, and wherein said step of slidingly engaging each beam with the deck plate comprises slidingly inserting part of the deck plate in each beam-channel.
<Desc/Clms Page number 4>
Advantageously, the deck plate is provided with a respective deck- channel formed along at least part of the length of each said edge, and wherein said step of slidingly engaging each beam with the deck plate comprises slidingly inserting part of a respective beam in each deck-channel.
Conveniently, each deck-channel is slidingly received within a respective beam-channel.
Preferably, the step of securing each deck-channel to the respective beam-channel by mechanically deforming the channels.
Advantageously, said mechanical deformation comprises crimping.
Conveniently, said mechanical deformation comprises rolling.
Preferably, each beam-channel is defined between a flange projecting outwardly from the beam and an inwardly turned lip carried by the outermost edge of the flange.
Advantageously, each said flange projects outwardly from a substantially planar side wall of the beam, and wherein the edge of the lip carried by each flange is spaced from the respective side wall to define therebetween an opening to the channel.
Conveniently, each deck-channel is defined between one surface of the deck plate and an inwardly turned lip carried by the respective edge of the deck plate.
<Desc/Clms Page number 5>
Preferably, each beam has a substantially planar upper surface which lies substantially co-planar with a substantially planar upper surface of the deck plate when the deck plate is engaged with the beams.
So that the invention may be more readily understood, and so that further features thereof may be appreciated, an embodiment will be now described, by way of example, with reference to the accompanying drawings, in which :-
FIGURE 1 is a perspective view from above and one end of an assembled deck plate in accordance with the present invention;
FIGURE 2 is a transverse cross-sectional view through part of the assembled scaffolding deck illustrated in Figure 1; and
FIGURE 3 is a perspective view from above and one end of a scaffolding deck plate in accordance with the present invention, illustrating the deck plate in an alternate position.
Figures 1 to 3 illustrate a scaffolding deck 1 of the present invention, which comprises a pair of elongate beams 2 slidably engaged with respective longitudinal edges of an elongate deck plate 3.
As illustrated most clearly in Figure 3, which shows the deck plate 3 being slidably engaged between the beams 2, the deck plate 3 is generally planar in configuration. The two longitudinal edges 4 of the deck plate 3 are substantially parallel with one another and each carries, preferably along substantially its entire length, a downwardly and inwardly turned plate-lip 5.
Each plate-lip 5 extends generally inwardly towards the central region of the deck plate 3 and is spaced from the undersurface 6 of the deck plate 3 in the region of the respective longitudinal edges 4. It will therefore be appreciated
<Desc/Clms Page number 6>
that between each plate-lip 5 and the undersurface 6 of the deck plate 3 in the region thereof, there is defined a longitudinal deck-channel 7 which preferably runs substantially the entire length of the deck plate 3. Each deck-channel 7 is open, at 8, along its entire length.
The deck plate 3 is preferably fabricated from steel and more preferably still from galvanised steel. Also, in a preferred embodiment, the deck plate 3 is provided with a plurality of lightening apertures (not illustrated) therethrough to reduce the overall mass of the deck plate 3 whilst maintaining strength and also presenting a substantially planar uppermost surface which is safe for persons to walk on.
Each beam 2 preferably comprises a box-type section extruded from a suitable metal such as, for example, aluminium. As illustrated most clearly in Figure 2, each beam 2 comprises a substantially planar uppermost surface 9 having a substantially planar side wall 10 depending perpendicularly therefrom.
Whilst the uppermost surface 9 of each beam 2 is substantially planar, the uppermost surfaces 9 can be provided with a plurality of longitudinal raised ridges 11 (illustrated only in Figure 2) or other suitable relief patterns to provide improved grip between the footwear of a person standing and walking on the scaffolding deck and the uppermost surfaces 9 of the beams 2. It will, of course, be appreciated from the drawings that when in use, the uppermost surfaces 9 of the beams 2 and the uppermost surface of the deck plate 3, are intended to be substantially horizontal so as to define a working platform.
As illustrated most clearly in Figure 2, the side wall 10 of each beam 2 carries a longitudinal flange 12 projecting outwardly from the opposite side of the side wall to the upper surface 9. The longitudinal flange 12 preferably runs substantially the entire length of the beam 2 and is spaced slightly below the
<Desc/Clms Page number 7>
junction between the side wall 10 and the upper surface 9. The flange 12 carries an upperwardly and inwardly directed beam-lip 13 which again preferably runs substantially the entire length of the beam 2. The inwardly directed beam-lip 13 is spaced from the flange 12 to define therebetween a beam-channel 14. The beam-lip 13 is also spaced from the side wall 10 so as to define an opening 15 to the beam-channel 14.
In order to assemble the deck plate 1 of the present invention, the beam- channel 14 of each beam 2 is slidably engaged with a respective deck-channel 7 of the deck 3. As illustrated most clearly in Figure 2, the inwardly-directed plate-lip 5 along each longitudinal edge of the deck plate 3 is slidably received within a respective beam-channel 14, whilst the beam-lip 13 defining the beamchannel 14 is similarly received within the deck-channel 7. The deck-channels and respective beam-channels therefore interlock in a sliding relationship to prevent non-axial movement therebetween.
Typically, each beam 2 is separately engaged with a respective longitudinal edge of the deck plate in turn, although it will be appreciated that the beams 2 could initially be arranged so as to be substantially parallel with one another and spaced apart by a width substantially equal to the width of the deck plate 3, whereafter the deck plate 3 could be slidingly engaged with each beam 2 substantially simultaneously. Figure 3 illustrates the two beams 2 being arranged substantially parallel to one another and spaced apart in this manner, with the deck plate 3 being slidably inserted therebetween in the direction indicated by arrow A.
In one embodiment of the present invention, it is envisaged that the deck-channels 7 and the beam-channels 14 will be dimensioned so that they engage one another as an interference fit. This type of arrangement will enable
<Desc/Clms Page number 8>
relative axial movement between the channels, and hence, between the beams 2 and the deck plate 3 providing a sufficient axial force is applied, but will prevent, or at least reduce the risk of inadvertent axial movement, thereby preventing accidental disengagement of the deck plate from the longitudinal beams 2 during, for example, manipulation of the scaffolding deck 1 during installation in the scaffolding system. However, it is also proposed that the beam-channels 14 and respective deck-channels 7 could be mechanically deformed so as to engage one another in a more permanent manner. For example, after the deck plate 3 has been slidably engaged with the longitudinal beams 2, the interlocked deck and beam-channels could be crimped at intervals along their length, by applying crimping forces along arrows Bl and B2 illustrated in Figure 2, in a manner known per se. Providing the crimping forces are of sufficient magnitude, this would mechanically deform the interlocked beam-channels and deck-channels into one another, thereby securing each deck-channel to the respective beam-channel and preventing axial movement therebetween. Alternatively, the mechanical deformation could be effected by rolling the interlocked channels along substantially their entire length in a manner known per se.
In the present specification"comprise"means"includes or consists of' and"comprising"means"including or consisting of.
The features disclosed in the foregoing description, or the following claims, or the accompanying drawings, expressed in their specific forms or in terms of a means for performing the disclosed function, or a method or process for attaining the disclosed result, as appropriate, may, separately, or in any combination of such features, be utilised for realising the invention in diverse forms thereof.
