The attaching arrangement 48 differs from the attaching arrangement 48 in that, in addition to a bayonet fitting comprising the bolt 92 extending through the hollow 74, the receiving member 70 also includes a bayonet fitting comprising a pair of opposed channel portions 192 (see Figure 7).
When the bolt 92 is received through the aperture 90, the L shaped slot 96 in the securing region 94 of the support member 16 receives the bolt 92 therein and by twisting the support member 16 in the direction indicated by the arrow D, the support member 16 is secured to the attaching arrangement 48.
Referring to Figure 7 and 10, each of the channel portions 192 defines a channel 192A. The securing region 94 is provided with two opposite radially outwardly extending pins 192B. When the support member 16 is inserted in to the hollow 74, the pins 192B are received in the channels 192A. When the pins 192B reach the lower end of the channels, the support member 16 can be twisted in the direction indicated by the arrow E to secure the support member 16 to the attaching arrangement 48.
Figures 8 and 9 show the steps for installing the attaching arrangement 48 and support member 16 on the base member 18 and thereafter installing decking 110 thereon. In order to install the decking, it needs to be mounted on the base member 18. As a result, the decking 110 has to be cut around the attaching arrangement 48.
The first V shaped clamping member 76 comprises an upper portion 76A of the V and a lower portion 76B. In the second embodiment, the upper portion 76A is in the form of a rectangular flat plate. The shape of the upper portion 76A facilitates the cutting of the decking 110 around the upper portion 76A, thereby making it easier to install.
The fastening means for fastening the first and second clamping members 76, 78 to each other is not shown in Figures 6 to 10. An example of fastening means is shown in Figure 11.
The fastening means comprises a first co-operating formation in the form of a first bolt receiving formation 182 attached to the receiving member 70 and to the upper portion 76A. A first through aperture 183 extends through the bolt receiving formation 182.
The fastening means further includes a second co-operating formation comprising a second bolt receiving formation 184 attached to the second clamping member 78. A second through aperture 185 extends through the second bolt receiving formation 184.
A tightening member in the form of a threaded fastener, such as a bolt 180, is received through the first and second through apertures 183, 185, and a nut 181 is screwed onto the bolt 180. The nut 181 is then tightened onto the bolt 180 thereby pulling the first and second clamping members 76, 78 towards each other and clamping them onto the base member 18.
Figures 12 to 16 show a third embodiment of the attaching arrangement 48 for holding a fall prevention apparatus 10. In Figures 12 to 16, the attaching arrangement 48 comprises many of the features of the first and second embodiments of the attaching arrangement 48 described above and these features are designated with the same reference numerals as in Figures 1 to 11.
The embodiment shown in Figures 12 to 16 includes the clamping means 72, which comprises the first and second clamping members 76, 78. The clamping means 72 further includes a locking arrangement 250 disposed within the hollow 74 of the receiving member 70.
The locking means 250 comprises the bolt 180, a locking member 252 and urging means in the form of a spring 254, such as a compression spring. An aperture 256 is defined in the receiving member 70 through which the bolt 180 can be inserted, thereby allowing the bolt 180 to be received in the hollow 74, as shown in Figures 15 and 16.
The locking member 252 and the spring 254 are disposed within the hollow 74 defined by the receiving member 70. The locking member 252 is pivotally mounted on the receiving member 70 and is pivotally movable between a locking position shown in Figure 16 and a non-locking position shown in Figure 15. The spring 254 urges the locking member 252 to the locking position.
The locking member 252 defines a hole 258 (see Figure 13) through which the bolt extends when the bolt 180 has been inserted in the hollow 74 via the aperture 256. When the locking member 252 is in the locking position, shown in Figure 16, it is canted relative to the bolt 180 so that the edge of the hole 258 engage the threads on the bolt 182, thereby securing the locking member 252 to the bolt 180.
In this position of the locking member 252, the bolt 180 can be screwed into the hole 258, thereby tightening the second clamping member 78 onto the I beam 18. The spring 254 ensures that the locking member 252 is pushed into engagement with the bolt 180.
When the locking member 252 is in the non-locking position, shown in Figure 15, the bolt 180 can be slid relative to the locking member 252 as indicated by the arrow A in Figure 28.
Referring to Figures 14 to 16, the first and second clamping members 76, 78 are arranged on the I beam 18. The bolt 180 is inserted through the second clamping member 78 into the receiving member 70 via the aperture 256. When the bolt 180 is so inserted, the locking member 252 is initially in the locking position, being urged to the locking position by the spring 254. The hole 258 in the locking member 252 is aligned with the aperture 256, so that insertion of the bolt 180 into the receiving member 70 causes the bolt 180 to be received by the hole 258.
With the locking member 252 in the locking position, the threads on the bolt engage the edge of the hole 258. Further insertion of the bolt 180 pushes the locking member 252 to the non-locking position, thereby allowing the bolt 180 to be inserted through the hole 258 to the position shown in Figure 15. With the locking member in the non-locking position, the bolt 180 can then be screwed into the hole 258 in the locking member 252.
The screwing of the bolt 180 into the hole 258 in the locking member 252 moves the locking member 252 to the locking position, as shown in Figure 16 and further screwing of the bolt 180 into the hole 258 tightens the first and second clamping members 76, 78 on the I beam 18.
The first and second clamping members 76, 78 can be removed from the T beam 18 by unscrewing the bolt 180 from the locking member 252.
Figures 17 to 19 show third embodiment of the attaching arrangement 48, which comprises many of the features of the first and second embodiments of the attaching arrangement 48 described above and these features are designated with the same reference numerals as in Figures 1 to 16.
In the embodiment shown in Figures 17 to 19, the upstanding member 16 is received within the tubular receiving member 70 by means of a bayonet fitting, as described above. Although not shown in Figures 17 to 19, a cylindrical pin or bolt extends across the inside of the receiving member 70 at the aperture 90 so that the upright member 16 can be secured thereto arranging the upright member so that the pin or bolt is received in the L shaped slot 96.
The attaching arrangement shown in Figures 17 to 19 comprises first and second clamping assemblies 280, 282. The first clamping assembly 280 includes the receiving member 70 for receiving the upstanding member 16.
Each of the first and second clamping assemblies 280, 282 comprises a fixed clamping member 284, in the form of a substantially flat plate, for engaging the top face of the upper flange 22A of the base member 18. The fixed clamping member 284 of each of the first and second clamping assemblies 280, 282 is formed of a plastics material.
Each of the first and second clamping assemblies 280, 282 further includes a moveable clamping member 286 which comprises a bolt receiving member 288 and a pair of downwardly extending clamping portions 290. The bolt receiving element 288 is substantially U shaped.
A tightening member in the form of bolt 289 is screwed into the bolt receiving element 288. The fixed clamping member 284 defines a pair of apertures 292 through which the downwardly extending clamping portions 290 can extend. Each movable clamping member 286 is a push fit into the apertures 292 of the respective fixed clamping member 284, and is slidable relative to the fixed clamping member 284.
Each of the clamping portions 290 includes a clamping foot 294 which can engage the underside of the upper flange 22A of the base member 18 to apply the clamping force thereto.
An elongate rectangular connecting member 296 is provided. The connecting member 296 separate from, and extends between, the first and second clamping assemblies 280, 282. The U shaped bolt receiving element 288 of each of the moveable clamping members 286 can receive the end regions of the connecting member 296 therethough. The clamping portions 290 of each moveable clamping member 286 extend downwardly on opposite sides of the connecting member 296.
The receiving member 70 defines a pair of aligned slots 312 (see Figure 21) to allow the connecting member 296 to extend through the receiving member 70.
In order to secure the attaching arrangement 48 to the base member 18, the first and second clamping assemblies 280, 282 are arranged thereon as shown in Figure 18.
The connecting member 296 is arranged to extend between the first and second clamping assemblies 280, 282, and extends beneath the bolts 289 in each of the bolt receiving elements 288.
The bolts 289 are then tightened into the bolt receiving elements 288, thereby engaging the connecting member 296 and urging the connecting member 296 onto the fixed clamping members 284.
The connecting member 296 transmits the clamping force applied by the bolts 289 to the fixed clamping members 284, thereby urging the fixed clamping members 284 into clamping engagement with the base member 18 (see Figures 18 and 19).
The moveable clamping member 286 is urged upwardly by the tightening of the bolt 289 so that the clamping portions 290 engage the underside of the upper flange 22A of the base member 18, thereby clamping the upper flange 22A between the fixed clamping member 284 and the clamping portions 290 of the moveable clamping member 286, and clamping the attaching arrangement 48 to upper flange 22A of the base member 18.
As indicated above, each of the fixed clamping members 284 is in the form of a respective substantially flat plate, which is engaged by decking disposed on the area adjacent the fall prevention apparatus 10 to form a floor. The substantially flat fixed clamping members 284 form a seal against the decking. The fixed clamping members 284 are formed of a plastics material.
It will be appreciated that the elongate connecting member 296 allows different widths of the upper flange 22A to be accommodated by the attaching arrangement 48. The co-operation of the fixed clamping members 284 with the moveable clamping members 286 allows different thicknesses of the upper flange 22A to be clamped by the first and second clamping assemblies 280, 282. In one embodiment, the upper flange 22A desirably has a thickness in the range of 8 Lo 20 mm, akhough the fixed and moveable damping members 284. 286 may be used with a base member 18 having an upper flange 22A with a thickness greater than 20 mm, Figures 20 to 41 depict a fourth embodiment of the attaching arrangement 48, which is similar to the third embodiment described with reference to Figures 17 to 19 and comprises many of the features of the third embodiment of the attaching arrangement 48 described above and these features are designated with the same reference numerals as in Figures 17 to 19. The first clamping assembly 280 of the attaching arrangement 48 shown in Figure 20 has a socket portion 302 on the fixed clamping member 284. The socket portion 302 is integral with the fixed clamping member 284 of the first clamping assembly 280, and is formed of the same plastics material as the socket portion 302.
In the fourth embodiment, the tubular receiving member 70 is separate from, and received in, the socket portion 302. The socket portion 302 defines a pair of opposed aligned slots 310 (see Figure 21), through which the elongate connecting member 296 can extend.
The tubular receiving member 70 also defines opposed slot 312 (see Figure 21) which can be aligned with the slots 310 in the socket portion 302 so that the elongate connecting member 296 can extend through the tubular receiving member 70 as well as through the socket portion 302.
Figure 21 shows an exploded view of the attaching arrangement 48 shown in Figure 20. Figure 21 shows a pin 492 which is inserted into the aperture 90 to co-operate with the L shaped slot 96 in the lower end region of the support member 16 to provide a bayonet fitting of the support member 16 in the receiving member 70.
Figures 22 and 23 shows the attaching arrangement 48 on the upper flange 22A of a base member 18. As can be seen from Figure 23, the upper flange 22A is clamped between the clamping feet 294 and the fixed clamping member 284 of each of the first and second clamping assemblies 280, 282.
The bolts 289 can be tightened to clamp the first and second clamping assemblies firmly to the upper flange 22A. By releasing the bolts 289, the attaching arrangement can be moved along the upper flange 22A, as indicated by the doubled headed arrow X. Figures 24 to 29 show fourth embodiment of the attaching arrangement 48 attaching the fall prevention apparatus 10 to the base member 18. Referring to Figures 24 and 25, the fall prevention apparatus 10 is shown attached to the base member 18 by the attaching arrangements 48. Figure 25 shows the first and second clamping assemblies 280, 282 clamping the upper flange 22A of the base member 18. The support members 16 are received in the receiving members 70, thereby attaching the fall prevention apparatus 10 to the base member 18.
The attaching arrangements 48 are clamped to the upper flange 22A of the base member 18 when the base member 18 is at ground level. The fall prevention apparatus 10 is secured to the attaching arrangements 48 and thereby attached to the base member 18 also at ground level. The base member 18 with the fall prevention apparatus attached thereto is then lifted by a crane, as shown in Figure 24A, to an upper storey of a building. Two ropes 600 are attached to the upper flange member 22A at the lower ends of the ropes 600 and at their upper ends to a hook 602. Cables 604 are attached to the hook 602 and to a crane (not shown) to lift the base member 18 and the fall prevention apparatus 10 attached thereto to an upper storey of a building.
As shown in Figures 26 and 27, the fall prevention apparatus 10 is arranged on the upper storey of the building adjacent an area 100 in which is disposed floor decking 450 comprising elongate parallel peak formations 452 and trough formations 454.
The supports 16 are received in the receiving members 70 and secured thereto by bayonet fittings as described above.
In Figures 26 and 27, the fall prevention apparatus 10 is arranged adjacent the floor decking 450 along a first edge 456 of the floor decking 450, where the peak formations 452 and trough formations 454 extend perpendicular to the first edge 456.
In Figures 28 and 29, the fall prevention apparatus 10 is arranged adjacent the floor decking 450 along a second edge 458 of the floor decking 450, where the peak formations 452 and trough formations 454 extend parallel to the second edge 458.
Referring to Figures 26 and 27, an edge trim 460 is provided adjacent the first edge 456. The edge trim 460 has a substantially L shaped end profile, having an elongate horizontal limb 460A and an elongate vertical limb 460B. The affixing members 462 are secured to the vertical limb 460B. Cut-outs 466 are formed in the horizontal limb 460A to receive the moveable clamping member 286 of the first clamping assembly 280 therethrough. In view of this, the cut-outs 466 enable the horizontal limb 460A to engage the upper flange 22A, which thus supports the edge trim 460.
The edge trim 460 is initially secured to the upper flange 22A of the base member 18 by the use of self drilling screws through the horizontal limb 460A. The edge trim 460 is affixed to the floor decking 450 by means of elongate flexible affixing members 462. The horizontal limb 460A rests on the fixed clamping member 284 of the first clamping assembly 280. The shape of the fixed clamping member 284, being in the form of a substantially flat radially extending plate, creates a seal between the horizontal limb 460A of the edge trim 460 and the fixed clamping member 284. This seal prevents leakage through the cut-outs 466 of the viscous concrete eventually poured over the floor decking 450 to form the floor.
End caps 470 are provided on the ends of the peak formations 452. Each end cap 470 has a substantially L shaped end profile, having a horizontal limb 470A and a vertical limb 470B. Cut-outs 472 are formed in the vertical limb 470B of those of the end caps 470 arranged over one of the attaching arrangements. The cut-outs 472 receive therethrough the connecting members 296 of each attaching arrangement 48. This allows the floor decking 450 to rest on, and be supported by, the upper flange 22A of the base member 18. The location of the attaching arrangements 48 so that they coincide with the trough formations 454 is desirable, because it minimises the amount of work involved in forming the cut-outs 472 and reduces the tendency for leakage of the concrete. However, it will be appreciated that the attaching arrangements can be located at any other suitable positions on the upper flange 22A.
Referring to Figures 28 and 29, a further edge trim 460 is provided adjacent the second edge 458, and is also affixed to the floor decking 450 by means of the elongate flexible affixing members 462. The further edge trim 460 also comprises an elongate horizontal limb 460A and an elongate vertical limb 460B. The affixing members 462 are secured to the vertical limb 460B.
The horizontal limb 460A defines the cut-outs 466 to receive the attaching moveable clamping member 286 of the first clamping assembly 280 therethrough. The upper flange 22A thus supports the further edge trim 460. The horizontal limb 460A engages the fixed clamping member 284 of the first clamping assembly 280 and creates a seal therebetween, in the same way as described above The floor decking 450 includes a horizontal edge member 474, which extends from the second edge 458 to a first of the peak formations 452.
Cut-outs 476 are formed in the edge member 474 to receive therethrough the moveable clamping member 286 of the second clamping assembly 282. This allows the edge member 474 to rest on the upper flange 22A of the base member 18, thereby allowing the floor decking 450 to be supported by the upper flange 22A of the base member 18.
The edge member 474 rests on the fixed clamping member 284 of the second clamping assembly 282. The shape of the fixed clamping member 284, being in the form of a substantially flat radially extending plate, creates a seal between the edge member 474 and the fixed clamping member 284. This seal prevents leakage through the cut-outs 476 of the viscous concrete eventually poured over the floor decking 450 to form the floor.
Figure 30 shows an exploded view of a modified version of the fourth embodiment of the attaching arrangement 48 shown in Figures 20 to 29. The attaching arrangement shown in Figure 30 comprises many of the features of the attaching arrangement 48 shown in Figures 20 to 29 and these features are designated with the same reference numerals as in Figures 17 to 19.
The attaching arrangement 48 shown in Figure 30 differs from the attaching arrangement 48 shown in Figures 20 to 29 as follows. The attaching arrangement 48 shown in Figure 30 possesses a connecting member 496 that is longer than the connecting member 296 shown in Figures 20 to 29.
Figure 31 shows an assembled view of the attaching arrangement 48 shown in Figure 30, from which it can be seen that the connecting member 496 comprises a main portion 496A extending between the first and second clamping assemblies 280, 282, and provides a carrying portion 496B that projects beyond the first clamping assembly 280 away from the second clamping assembly 282.
The length of the main portion 496A is dependent upon the width of the upper flange 22A. The length of the carrying portion 496B is also dependent upon the width of the upper flange 22A.
The attaching arrangement 48 includes a mounting member 500 which can be provided on the carrying portion 496B. The mounting member 500 may be slidable along on the carrying portion 496B.
The mounting member 500 may comprise a substantially rectangular main portion 502 and at least one securing flange 504 on the main portion 502. In the embodiment shown, the mounting member 500 has two securing flanges 504 on respective opposite sides of the main portion 503.
Each securing flange 504 defines a plurality of securing apertures 506 for receiving fastener (such as self drilling screws) therethrough. The fasteners are drilled through the apertures 506 in the flanges 504, into the horizontal limb 460A of the edge trim 460, thereby securing the edge trim 460 to the mounting members 500 and, thereby, to the base member 18 via the attaching arrangements 48. Thus, when a plurality of the attaching arrangements 48 are clamped to the base member 18, the edge trim 460 can be mounted on the base member 18 by fastening the edge trim 460 to the mounting member 500 on the connecting member 496 of each of the attaching arrangements 48.
The mounting member 500 being slidable on the carrying portion 496B of the connecting member 496 allows the position of the mounting member 500 on the carrying portion 496B to be adjusted therealong. Thus, when the edge trim 460 is attached to the mounting member 500, the position of the edge trim relative to the base member 18 can be adjusted by sliding the mounting member 500 along the carrying portion by 496B.
The attaching arrangement 48 also includes an affixing member 510 to affix the edge trim 460 to the attaching arrangement 48. The affixing member 510 comprises a first securing portion 512 for securing the affixing member 510 on the first clamping assembly 280. The first securing portion 512 may define an aperture 514 to allow the first securing portion 512 to extend around the receiving member 70. The aperture 514 allows the affixing 510 member to be attached to the receiving member 70.
If desired, the first securing portion can be configured to engage the receiving member 70 and the support member 16, thereby forming a seal therebetween to prevent concrete entering the receiving member 70. This engagement may also reduce play between the receiving member 70 and the support member 16.
The first securing portion 512 is annular and is configured to receive the receiving member 70 therein. The first securing portion 512 comprises a substantially flat annular member 512A and a cylindrical member 512B on the substantially flat annular member 51 2A.
The affixing member 510 comprises an elongate flexible second securing portion 516 for securing the affixing member 510 to the edge trim 460 (see Figures 33 to 41).
The second securing portion 516 define a plurality of apertures 518, through a selected one of which a fastener 520 (see Figure 34), such as a bolt or a screw, can extend to fasten the second securing portion 516 to the edge trim 460.
Figures 32 and 33 show the mounting member 500 on the carrying portion 496B of the connecting member 496, and the edge trim 460 attached to the mounting member 500. Figures 32 and 33 also show the attachment of the affixing member 510 to the edge trim 460. Figure 34 is a sectional side view of the view shown in Figure 32, from which it can be seen that the receiving member 70 is received within the substantially flat annular member 51 2A and within the cylindrical member 51 2B.
In Figure 32, the attaching arrangement 48 is clamped onto the upper flange 22A of the base member 18, at a safe level, such as ground level. In the first stage of securing the edge trim 460 on the base member 18, the horizontal limb 460A of the edge trim 460 is attached to the mounting member 500, and the mounting member 500 is then slidably mounted on the carrying portion 496B of the connecting member 496. In Figure 32, the affixing member 510 is pivoted away from the edge trim 460 so as not to inhibit the mounting of the edge trim 460 on the attaching arrangement 48.
Figures 33 and 34 show the second stage of securing the edge trim 460 on the base member 18. In this stage, the affixing member 510 is pivoted to the position at which the second securing portion 516 engages the vertical limb 460B. In Figures 32 and 33, it is shown that the vertical limb 460B has a lip portion 461 to which the second securing portion 516 of the affixing member 510 is attached. The fastener 520 fastens the second securing portion 516 to the lip portion 461, thereby affixing the edge trim 460 to the attaching arrangement 48, and thereby mounting the edge trim 460 on the base member 18. When edge trim 460 has been mounted on the base member 18, as described above, the fall prevention apparatus 10 can be attached to the base member 18 by means of the attaching arrangements 48, as shown in Figure 35 and 37. The edge trim 460 is shown attached to the receiving members by the affixing members 510, which are attached to the lip 461. The edge trim 460 is also attached to the connecting members 496 by means of the mounting members 500, as shown in Figure 37.
After the fall prevention apparatus 10 has been attached to the base member 18 by the attaching arrangements 48, the base member 18, with the fall prevention apparatus 10 and the edge trim 460 thereon, can then be lifted, for example by the use of a crane, to the area 100 at which the floor is to be installed, in an upper storey of a building.
Figure 35A shows the lifting of the base member 18 with the fall prevention apparatus 10 attached thereto to an upper storey of a building. Two ropes 600 are attached to the upper flange member 22A at the lower ends of the ropes 600 and at their upper ends to a hook 602. Cables 604 are attached to the hook 602 and to a crane (not shown) to lift the base member 18 and the fall prevention apparatus 10 attached thereto to the upper storey of a building.
Referring to Figure 39, cut-outs 466 are formed in the horizontal limb 460A. The cut-outs 466 are provided to receive the moveable clamping member 286 of the first clamping assembly 280 therethrough, so that the horizontal limb 460A can engage the upper flange 22A. The edge trim 460 is thus supported by the base member 18.
The horizontal limb 460A also engages the fixed clamping member 284 of the first clamping assembly 280. The fixed clamping member 284 is formed of a plastics material. In view of this, a seal is created between the horizontal limb 460A and the fixed clamping member 284, thereby preventing leakage through the cut-outs 466 of concrete eventually poured over the floor decking 450 to form the floor.
Referring to Figures 38 and 39 the area 100 is shown, in which floor decking 450 is disposed. The floor decking 450 comprises elongate parallel peak formations 452 and trough formations 454.
The floor decking 450 is arranged adjacent the fall prevention apparatus 10. In Figures 38 and 39, the fall prevention apparatus 10 is arranged along an edge of the floor decking 450 where the peak formations 452 and trough formations 454 extend perpendicular to the fall prevention apparatus 10.
End caps 470 are provided on the ends of the peak formations 452. Each end cap 470 has a substantially L shaped end profile, having a horizontal limb 470A and a vertical limb 470B. Cut-outs 472 are formed in the vertical limb 470B of those of the end caps 470 arranged over one of the attaching arrangements. The cut-outs 472 receive the connecting members 296 of each attaching arrangement 48 therethrough. This allows the floor decking 450 to rest on, and be supported by, the upper flange 22A of the base member 18. The floor decking 450 can be secured to the upper flange 22A of the base member 18 by fasteners, such as self drilling screws.
As shown in Figure 38, the edge trim 460 is then secured to the decking 450 by further affixing members 462, which extend from the lip 461 to the end caps 470.
In Figures 40 and 41, the fall prevention apparatus 10 is shown arranged adjacent the floor decking 450 in a region where the peak formations 452 and trough formations 454 extend parallel to the fall prevention apparatus 10.
A further edge trim 460 is affixed to the receiving members 70 by means of the elongate flexible affixing members 510 as described above. The further edge trim 460 also comprises an elongate horizontal limb 460A and an elongate vertical limb 460B.
The horizontal limb 460A defines the cut-outs 466, which receive the moveable clamping member 286 of each first clamping assembly 280 therethrougb. The upper flange 22A thus supports the further edge trim 460.
