Applicant: RISING ACRES PTY LTD A.C.N. 070 921 970 Invention Title: A DEVICE FOR MOUNTING A SAFETY RAIL AND/OR WALKWAY The following statement is a full description of this invention, including the best method of performing it known to us: 2 A DEVICE FOR MOUNTING A SAFETY RAIL AND/OR WALKWAY Background and Field of the Invention The present invention relates to a device for mounting a safety rail and/or walkway to a structural frame of a building to prevent a person falling therefrom.
Occupational health and safety requirements often prescribe that safety rails and walkways must be erected around the perimeter of a roof of a building while being constructed. In the past, safety rails and walkways have been erected around a roof using complex scaffolding systems that are often time consuming to assemble and expensive to hire.
It is an object of the present invention to provide alternative means for mounting a safety rail and/or walkway to a building frame.
Summary of the Invention According to the present invention there is provided a device for mounting a safety rail and/or walkway to a building frame including upright stud members and a top plate member that spans between upper ends of adjacent upright stud members, the device including: two interconnected engaging members that in use, can be positioned on an upper end of the upright stud member and one of the engaging members overlaps a part of the top plate member and thereby enables the device to be directly fastened to the upright stud member and/or top plate member of the building frame; a load carrying member forming part of, or capable of being connected to the safety rail and/or walkway, the load carrying member connected to the engaging members.
It is possible that the engaging members can be interconnected so as to form an L-shaped member that contacts adjacent sides of the upright stud member.
However, it is preferred that the engaging members be \\melb files\home$\Byron\Keep\speci\P 51714 .2.doc 23/12/03 3 interconnected in a spaced relationship and extend from a base plate.
According to the present invention there is also provided a device for mounting a safety rail and/or walkway to a building frame including upright stud members and a top plate member that spans between upper ends of adjacent upright stud members, the device including: two engaging members that are interconnected in spaced relationship so that in use, the engaging members can be positioned on opposite sides of an upper end of the upright stud member and at least one of the engaging members overlaps a part of the top plate member and thereby enables the engaging members to be directly fastened to the upright stud member and/or top plate member of the building frame; a load carrying member forming part of, or capable of being connected to the safety rail and/or walkway, the load carrying member connected to the engaging members such that a load applied to the load carrying member tends to pivot the device and thereby forces the engaging members against the sides of the upright member.
It will be appreciated that the engaging members can be fastened to the upright stud member and/or the top plate member using any suitable fastening means including bolts, screws and nails.
An advantage provided by the present invention is that forces applied to the device via the load carrying member acts as a moment on the device and forces the engaging members against the upright and top plate members so that frictional forces, in addition to the fastening means, assists in preventing the device from sliding down the upright members.
A further advantage provided by the invention is that as the load applied to the device increases the frictional forces between the engaging members and the upright member also increases.
\\melb_files\homeS$\Byron\Keep\speci\P 51714 .2.doc 23/12/03 4 It will be appreciated that the load carrying member may form part of a safety rail or walkway or provide a foundation to which a safety rail or walkway can be mounted.
It is preferred that device includes a base plate and the engaging members are in the form of elongated plates that extend from the base plate such that in use, the elongated plates extend longitudinally along the upright stud member.
In the situation when only one of the engaging members is adapted to overlap the top plate member for fastening thereto, it is preferred that the load carrying member and said engaging member for overlapping the top plate extend from opposite sides of the base plate of the device.
It will be appreciated that the base plate, like the engaging members, can be fastened to the upright stud member of the building frame using any suitable means including bolts, screws and nails.
According to the present invention there is also provided an assembly including: a plurality of the devices according to any one of the preceding claims mounted to a building frame; and one or more safety rails, walkways or alike safety barriers directly or indirectly mounted to and spanning between the load carrying members of the devices.
Brief Description of the Drawings A preferred embodiment of the present invention will now be described with reference to the following drawings, of which: Figure 1 is a front perspective view of a device fitted to a building frame for mounting a safety rail and/or walkway thereto; Figure 2 is a side view of the device in Figure 1 fitted to the building frame; \\melb_files\home$\Byron\Keep\speci\p5171 4 .2.d o c 23/12/03 5 Figure 3 is a back perspective view of the device illustrated in Figures 1 and 2; Figure 4 is a front view of the device on which a safety rail has been mounted; and Figures 5 to 8 are a series of examples in which the device shown in Figures 1 to 4 has been used for mounting a safety rail to a building framework.
Detailed Description of a Preferred Embodiment The preferred embodiment of the present invention is a device for mounting a safety rail and/or walkway to a building structural frame including upright stud members and a top plate member that spans between upper ends of adjacent upright stud members. The top plate member 14 may have a horizontal or inclined orientation depending on the relative heights of the upright stud members The device can either form part of, or be used for mounting a safety rail and/or a walkway around the perimeter of a building to prevent a person falling from the building during construction.
The device of the preferred embodiment includes: a base plate 10 for positioning against a face defining the width of the upright stud member 11; a load carrying member 12 extending from the base plate 10; and a pair of engaging members in the form of elongated flanges 13a and 13b extending from opposite sides of the base plate Although not shown in the drawings, the base plate and flanges 13 form a C-shape when seen in an elevated view.
The base plate 10 of the device is essentially a flat piece of metal and the flanges 13 extend outwardly from the base plate 10 at a spacing suitable to be fitted over the width of the upright stud member 11 and for engaging opposite sides thereof.
As can bee seen in Figure 3, flanges 13a extends above and below the base plate 10. The length of the other flange 13b is limited to the height of the base \\melb_files\home$\Byron\Keep\speci\P5171 4 .2.doc 23/12/03 6 plate 10 and therefore does not extend above and below the base plate 10. Portions of the flange 13a extending above the base plate 13a have an opening 15 for receiving a fastening means such as a bolt, screw or nail for attaching the device to the top plate 14 of the building frame. Additional openings 16 are also formed in the base plate 10 and may also be formed in the other flange 13b for receiving fastening means for securing the device to the building frame.
In use, the device is secured to a stud member 11 by placing the flanges 13 against opposite sides of the upright member 10 with the load carrying member 12 extending outwardly of the building. As can be seen in Figure 1, the base plate 10 is positioned so that it abuts against the top plate 14 of the building frame such that a bolt, screw or nail can be received by hole 15 of flange 13a to secure the device to the top plate 14. In addition, a load applied to the load carrying member 12 applies a moment to the base plate 10 which tends to pivot the device and forces the flanges 13 against the top plate 14 and upright stud member 11 so that frictional forces assist in securing the device in position.
As can be seen in the figures the load carrying member 12 is the form of a rectangular steel section that is welded at one end to the base plate 10. The load carrying member 12 and flange 13a overlaps the top plate 14 of the building frame extend from opposite sides of the base plate As can be seen in Figure 4, a post and safety rail assembly can be mounted to the load carrying member 12 by a sleeve 17 slidably mounted over the load carrying member 12. The sleeve 17 and load carrying member 12 include pairs of co-operating holes 18 which when aligned allow fastening pins 19 to be passed through the holes 18 to secure the sleeve 17 in position on the load carrying member 12.
\\melb_files\home$\Byron\Keep\speci\P51714.2.doc 23/12/03 7 Figures 5 to 8 illustrate four different scenarios in which the device is used for mounting a safety rail around the perimeter of a building. Specifically, in the case of Figure 5, the device is used for mounting a safety rail around the perimeter of a building during the construction of the roof truss of a single storey building. Figures 6 and 7 illustrate the device fitted to the stud members of a lower floor of a multi-storey building during the construction of the floor and frame of the second level of the building. Finally, Figure 8 illustrates the device fitted to the stud members of a second floor of a building for mounting a safety rail during a construction of the roof of the building.
Furthermore, although not shown in the figures, the load carrying member 12 can also form the base of a walkway. Specifically, by mounting a plurality of the devices to a series of upright stud members 12 of the building frame, planks can be positioned to span the load carrying members 12 to form a walkway. A safety rail may also be fitted if required.
A person skilled in the art of the present invention will understand that modifications may be made to the preferred embodiment without departing from the spirit and scope of the present invention.
