Description
SCAFFOLDING
This invention relates to scaffolding and in particular to guard frames for attachment between vertical members of a scaffolding structure.
There is a requirement that such guard rails should be capable of being positioned in operating position on an upper level of an associated scaffolding by operators standing on a lower level.
This mounting of such guard rails is problematical particularly if the guard rail has a wedge-type coupler at one or both ends of the guard rail which has a hook-shaped fastening member which engages an open topped support member carried by a vertical member of the scaffolding and a wedge member moveable between an inoperative position to an operative position in which it wedges a pivoting bracing member of the coupling against the vertical scaffold member below the support member to prevent disengagement of the hook-shaped fastening member from the support member.
It is an object of the present invention to provide a hand tool which can be used by operators stood one at each end of the guard frame to raise the guard frame into its operating position.
Thus according to the present invention there is provided a hand tool for positioning a scaffolding guard frame having upper and lower rails in its operating position on an upper level of an associated scaffolding by operators standing on a lower level, at least one end of the guard frame having a wedge-type coupler which has a hook-shaped fastening member which engages an open topped support member carried by a vertical member of the scaffolding and a wedge member moveable between an inoperative position to an operative position in which it wedges a pivoting bracing member of the coupling against the vertical scaffold member below the support

member to prevent disengagement of the hook-shaped fastening member from the support member, the tool comprising a pole member with upper and lower hook portions which receive end portions of the upper and lower rails for lifting one end of the guard frame to engage its hook-shaped member with the associated support member, and a coupler operating member carried by the pole which can be manipulated by the operator, after engaging the hook-shaped fastening member with its associated support member and disengaging the hook portions from the rails, to move the wedge member to its operative position to wedge the bracing member against the vertical scaffold member to prevent disengagement of the hook-shaped fastening member from the support member and thus secure the guard frame to the support member of the scaffolding.
The tool preferably has a bracing member support carried by the pole to assist in holding the bracing member in a disengaged position prior to its engagement with the vertical scaffold member.
The bracing member support can be rotated about the pole member through 180 degrees so that the tool is not handed and can be used at either end of the guard frame.
The pole member may carry a pull-down member for contact with one of the rails to pull the guard frame downwards after the hook portions of the tool have disengaged the rails to engage the hook-shaped fastening member in its associated open-topped support member.
The present invention also provides a method of positioning a scaffolding guard frame having upper and lower rails in its operating position on an upper level of an associated scaffolding by operators standing on a lower level and using two hand tools as described above, the method comprising providing two hand tools for use by the operators stood one at each end of the guard frame, raising the guard rail to the upper level using the upper and lower hook portions provided on each hand tool which receive end portions of the upper and lower rails, lowering the guard rail by
3
lowering the hand tools to engage the hook-shaped fastening member or members with their respective support members, disengaging the hook portions from their respective rails, and manipulating the coupler operating members carried by each tool to move the wedge members to their operative positions to wedge the bracing members against the vertical scaffold members to secure the guard frame to the support members of the scaffolding.
The present invention will now be described with reference to and as shown in the accompanying drawings in which :-
Figure 1 shows a perspective view of a hand tool in accordance with the present invention;
Figure 2 shows two operators using the hand tool of Figure 1 to mount a guard rail in its operating position on an upper level of an associated scaffolding;
Figures 3 to 8 show details of the wedge-type coupler used to secure the guard rail in its operating position;
Figures 9 to 12 show the sequence of moves used in mounting the guard frame on the scaffolding, and
Figures 13 and 14 show how a bracing member support of the tool can be rotated about the pole member of the tool so that the tool is not handed and can be used on both ends of the guard rail.
Referring to the drawings, as shown in Figures 2 and 9 to 12, a scaffolding guard rail 100 has upper and lower rails 100a and 100b, inclined members 100c and vertical end members 100d.
At each upper corner of the guard rail a coupler 10 is provided of the so-called wedge-type coupler 10 which has a body member 11 attached to upper rail 100a
4
and adjacent vertical end member 100d. Each coupler 10 is used to connect the guard rail 100 to adjacent vertical scaffold member 13 which has an open topped cup-like support member 14. A hook-shaped member 15 extends from body member 11 for engagement inside the open topped support member 14 (see Figures 5 and 6) provided on the vertical scaffold member 13.
The coupler 10 includes a bracing member 16 pivoted by a rivet pin 17 on the body memberl 1 and has a first bracing surface 18 for contact with the vertical scaffold member 13 below the support member 14 to prevent disengagement of the hook-shaped member 15 from the support member 14 of the vertical scaffold member. A wedging member 19 captive via a slot 19a on pin 17 acts between a bracing surface 20 on the body member 11 and a second bracing surface 21 on the bracing member 16 to hold the first bracing surface 18 of the bracing member 16 against the vertical scaffold member 13 to prevent disengagement of the hook-shaped member 15 from the support member 14 of the vertical scaffold memberl 3.
As can be seen from the drawings the bracing member 16 and wedging member 19 are both mounted within the body member 11 which comprises a generally U-shaped component with which the hook-shaped member 15, in the form of two hook-shaped portions 15a, is integrally formed. A fill in piece 15b (see Figure 6) is welded between hook-shaped portions 15a.
In accordance with the Applicants earlier pending patent application No. 1201697.8 the coupler may be provided with a fastening member in the form of a bolt 22 and co-operating nut 23 (see Figures 3 to 8) which, when in its operating position, extends through slots 24 provided in body member 11. Bolt 22 extends through the body member 11 and engages the bracing member 16 at a location 25 displaced from its pivotal attachment at 17 to the body member to prevent pivoting of the bracing member 16 relative to the body member 11 so that the hook-shaped member 15 coupler cannot disengage the support member 14 of the vertical scaffold member.
5
Each lower corner of the guard rail is provided with a coupler 10' which has a hook-shaped member 15 only and no bracing member 16 or wedge member 19. These lower hook-shaped members 15 again engage support members 14 on the vertical members 13.
In accordance with the present invention a hand tool 30 is provided which has a pole member 31 with upper and lower hook portions 32 and 33 which receive end portions of the upper and lower rails 100a and 100b of the guard rail for lifting one end of the guard frame to engage its hook-shaped member 15 with the associated support member 14. Two such tools are used by two operators "O" one at each end of the guard rail to raise the guard rail into its upper operating position as shown in Figure 2.
Each tool also carries a coupler operating member 34a, 34b which can be manipulated by the operators (after engaging the hook-shaped fastening members 15 with their associated support members 14 and disengaging the hook portions 32 and 33 from the rails) to move the wedge members 19 to their operative positions in which the wedge members 19 fall between the bracing surfaces 20 and 21 to wedge the bracing members 16 against the vertical scaffold members 13 to prevent disengagement of the hook-shaped fastening members 15 from the support member 14 and thus secure the guard framelOO to the support members 14 of the scaffolding. The operating members 34a, 34b are brought into contact with wedge members 19 by moving the tools perpendicular to the vertical members 13 as indicated by the arrow X of Figure 12.
As can be seen in Figures 9 to 11, the wedge 19 of each coupler 10 is inserted within the base of each body member 11 of the coupler. Each pole 31 is also preferably provided with a bracing member support 35 which is located to assist in holding the bracing member in a disengaged position well clear of the vertical member 13 and support member 14 prior to its engagement with the vertical scaffold member. The supports 35 are also used to release the wedges 19 when it is desired to remove the guard frame 100 as described below.
6
The bracing member support 35 can be rotated about the pole member on a sleeve 35a through 180 degrees (see Figures 13 and 14) so that the tool is not handed and can be used at either end of the guard frame. The support 35 is located in its two positions by a removable pin 36.
Each pole 31 also carries at its upper end a pull-down member 37 for contact with one of the rails to pull the guard frame downwards (as indicated by the arrow Y in Figure 11) after the hook portions 32 and 33 of the tool have disengaged the rails to ensure that the hook-shaped fastening members 15 engage their associated open-topped support members 14. For convenience the pull-down members 37 may be mounted on the upper ends of upper hook portions 32.
Pull-down members 37 also include a cup hook 38 which can be engaged in the open-topped support members 14 to move the vertical members 13 slightly horizontally if difficulty is experienced in aligning the hook-shaped members 15 with the support members 14.
The guard rail is mounted in its upper operating position as follows.
Two operators are provided with tools 30 as described above and are located one at each end of the guard frame.
The operators engage the upper and lower hook portions 32 and 33 with the upper and lower rails 100a and 100b of the guard frame 100 and lift the guard frame as shown in Figures 2 and 9. The hook-shaped members 15 of the upper and lower couplers 10 and 10' are then positioned above their respective support members 14 as shown in Figure 10 and the poles of the tools are lowered to engage the members 15 into the support members 14(see Figure 11). As the poles are lowered and the members 15 engage the support members 14 the upper and lower hook portions 32 and 33 disengage the rails 100a and 100b and the pull-down members 37 contact the top of the upper rail 100a to ensure that the hook-shaped members 15 engage the support members 14 (see Figure 11).
7
The operators then move their poles towards the associated vertical member 13 as indicated by the arrow X in Figure 12 to drive the wedge members 19 from within the coupling body members 11 to allow the wedge members 19 to drop between the bracing surfaces 20 and 21 to wedge the bracing members 16 against the vertical scaffold members 13 to prevent disengagement of the support members 14 and secure the guard frame in position.
With the guard rail located in its upper operating position, after the installation of suitable upper level decking, the operators can safely climb to the upper level and drive the wedges firmly home to complete the installation of the guard frame.
The guard frame is demounted by the operators by driving the wedges upwards using the members 35 and then using members 35 to rest the wedges inside the body members 11 so that the frame can be lifted clear of the support members 14 by engaging the upper and lower hook portions 32 and 33 with the upper and lower rails 100a and 100b.
The present invention thus provides a hand tool and a method for safely mounting a guard frame fitted with a wedge-type coupler in an upper operating position by two operators standing on a lower level.
