Description

STEEL FRAME SYSTEM
FIELD OF THE INVENTION
The present invention relates to a steel frame system for a building.
The present invention relates to a steel frame system for a multiple storey building.
The present invention also relates to a multistory building that includes the steel frame system of the invention.
BACKGROUND
Steel frame systems are a lightweight (compared to equivalent timber frame systems) and termite proof option for use in the construction of buildings .
The structural properties of members of steel frame systems can be specified with accuracy and with consistency across members of the same type.
In any multi-storey building, there is a need to have load transfer from upper storeys of the building to the ground.
In buildings that are constructed using load- bearing studs in walls, such as buildings constructed from steel frame systems, it is highly recommended to have the load-bearing studs aligned vertically in each storey of the buildings . If the load-bearing studs are not aligned vertically, there will be eccentric loads, with a need for horizontal load transfer, and generally this is not desirable.
The steel frame system of the invention facilitates the construction of a building with vertical load transfer through multiple storeys to the ground.
The above description is not an admission of the general knowledge in Australia or elsewhere. SUMMARY OF THE INVENTION
In broad terms, the present invention is a steel frame system for a multi-storey building, with the steel frame being characterised by vertical load-bearing studs that form at least part of a wall frame of a lower storey of the building that extend into a floor cavity of a floor above the lower storey and form mounting locations for floor joists of the floor and, as a consequence of
extending into the floor cavity, facilitate connecting vertical load-bearing studs of an upper storey frame in vertical alignment with the vertical load-bearing studs of the lower storey frame.
More particularly, the present invention provides a steel frame system for a multi-storey building, which may be any suitable number of storeys, with the building including successive storeys and a floor cavity separating successive storeys, with the steel frame at least
including :
(a) a lower storey frame including vertical load-bearing studs;
(b) an upper storey frame connected to the floor frame and including vertical load-bearing studs that are aligned vertically with studs in the lower storey frame, whereby there is load transfer directly through the vertical studs in the upper storey frame to the vertically aligned studs in the lower storey frame ; and
(c) a floor frame connected to and extending transversely from the lower storey frame;
with the steel frame system being characterised in that the studs of the lower storey frame extend into the floor cavity that separates the lower storey frame and the upper storey frame and in that the floor frame is connected to the studs .
The above feature of vertical load-bearing studs of the lower floor frame extending into the floor cavity that separates the lower storey frame and the upper storey frame makes it possible to connect a floor frame
accurately and conveniently to the lower storey frame . This provides an opportunity to decrease the construction time and minimise construction issues . The above feature also makes it possible to accurately and conveniently align vertically the vertical load-bearing studs of the upper storey frame with the studs of the lower floor frame. This is possible because the studs of the lower floor frame extend into the floor cavity, making alignment of the studs visually easier.
The lower storey frame may define the upper and lower levels of the floor cavity.
The floor frame may include a plurality of floor joists .
Each floor joist may include an upper chord member, a parallel lower chord member, and a plurality of cross-bracing web members interconnecting the upper and lower chord members .
Each upper chord member and lower chord member may be connected to one of the studs of the lower storey frame .
The lower storey frame may include an upper plate that extends across and is connected to the upper ends of studs of the lower storey frame and defines an upper level of the floor cavity.
The upper plate may be a channel section with a web and two sides extending from the web and include notches in at least one side at spaced intervals along the length of the upper plate to allow the upper chord members of the floor joist to be positioned to extend into the upper plate.
The channel section of the upper plate may be formed from of steel, typically lightweight steel sheet.
The lower storey frame may include a lower plate that extends across and is connected to the studs of the lower storey frame and defines a lower level of the floor cavity.
The lower plate may be a channel section with a web and two sides extending from the web and include apertures in the web at spaced intervals along the length of the lower plate to allow the studs of the lower storey frame to be located to extend through the lower plate into the floor cavity.
The lower chord members of the floor joists may be located on the lower plate .
The channel section of the lower plate of the lower storey frame may be formed from of steel, typically lightweight steel sheet .
Typically, the upper plate and the lower plate of the lower storey frame are parallel and spaced apart.
Typically, the spacing between the upper plate and the lower plate of the lower storey frame is the depth of the floor cavity with a small crib allowance.
The studs may be formed from C-section channels made of steel, typically lightweight steel, for example by roll forming steel sheet, typically 0.5—1.2mm thick sheet.
The upper and lower chord members and the cross- bracing web members of the floor joists may be made from steel , typically lightweight steel , for example by roll forming steel sheet, typically 0.5—1.2mm thick sheet.
The upper and lower chord members of the floor joists may also be boxed such that 2 chord C-sections are nested inside each other .
The upper storey frame may be the same structure as the lower storey frame.
The present invention also provides an opportunity to construct the above-described floor joists as prefabricated modules off-site that can be lifted as units into position on the lower floor frame on a building site in the construction of the building.
The present invention also provides an opportunity to construct the lower and upper storey frames as modules off-site that can be lifted as units into position in the construction of the building.
The load-bearing studs may be for internal walls .
The load-bearing studs may be for external walls .
The steel frame of the present invention is suitable to multiple storey buildings . There is an increasing move towards the construction of multiple storey buildings , including buildings that are more than two storeys. The invention is an opportunity for all of the steel requirements for buildings of this size. By way of comparison, typically 10 plus storey high rise
buildings are more complicated structures that require a combination of materials, particularly steel and
reinforced concrete .
The present invention also provides a multistorey building that includes the above-described steel frame system.

Figure 7 is a side elevation of a floor joist that forms part of the steel frame system shown in Figures 1-6. DESCRIPTION OF EMBODIMENT OF THE INVENTION
The multi-storey building shown in the Figures includes a lower storey 3, an upper storey 5, and a floor 7 that separates the upper and lower storeys .
The building comprises a steel frame system that is the main structural component of the building and is described further below.
The building also comprises external walls (not shown) and internal walls (not shown) . The walls may be of any suitable construction.
The steel frame system shown in the Figures includes :
(a) a lower storey frame that includes a
plurality of vertical load-bearing studs 9, a plurality of parallel spaced-apart horizontal lower plates 17 (only one of which is shown in the Figures) , and a plurality of parallel spaced-apart
horizontal upper plates 19 (only one of which is shown in the Figures) ;
(b) a floor frame connected to and extending transversely from the lower storey frame, with the floor frame comprising a plurality of parallel, horizontal floor joists 25; and
(c) an upper storey frame connected to the
floor frame and including vertical load- bearing steel studs 33 that are aligned vertically with studs 9 in the lower storey frame, whereby there is load transfer directly through the vertical studs 33 in the upper storey frame to the vertically aligned studs 9 in the lower story frame; The lower plates 17 and the upper plates 19 of the lower storey frame define the upper and lower levels of a floor cavity 13 (see Figure 6) between the upper and lower storeys 3, 5.
In effect, the lower floor frame is constructed to define the frame for the lower floor and the floor cavity 13. Specifically, the lower floor frame is formed so that the studs 9 extend into the floor cavity 13 of the floor 7 and the floor joists 25 are connected to the studs 9. This arrangement provides an in-built stabilisation of the floor joists 25 from roll-over as well as having a ready-made connection point for the roof joists 25 to the wall frame .
Each floor joist 25 includes a lower chord member 21, a parallel upper chord member 23, and a cross- bracing web member 27 interconnecting the upper and lower chord members 21, 23.
The connections are via any suitable fasteners , such as locating fasteners, self-tapping fasteners, and bolts . The connections are between the studs 9 and each of the upper and lower plates 17, 19 and each of the upper and lower chord members 21, 23.
Each upper plate 19 of the lower storey frame is a channel section with a web and two sides extending from the web and includes notches in at least one side at spaced intervals along the length of the upper plate 19 to allow the upper chord members 23 of the floor joists 25 to be positioned to extend into the upper plate 19.
Each lower plate 17 of the lower storey frame is a channel section with a web and two sides extending from the web and includes apertures in the web at spaced intervals along the length of the lower plate 17 to allow the studs 9 of the lower storey frame to be located to extend through the lower plate 17 into the floor cavity 13.
As described above, the above feature of the vertical load-bearing studs 9 of the lower floor frame extending into the floor cavity 13 makes it makes it possible to locate the floor frame accurately and
efficiently on the lower storey frame. This provides an opportunity to decrease the construction time and minimise construction issues. In addition, described above, the above feature also makes it possible to accurately and conveniently align vertically the vertical load-bearing studs 9 , 33 of the upper storey frame with the lower floor frame. This is possible because the studs 9 of the lower floor frame extend into the floor cavity 13, making alignment of the studs 9, 33 visually easier.
The upper storey frame is the same structure as the lower storey frame.
The lower storey frame, the upper storey frame and the floor joists 25 can be constructed off-site as modules and transported to site and lifted into position.
Alter the construction of a reinforced concrete floor slab or other suitable floor system is completed, the lower storey frame modules can be lifted into position and connected to the floor slab to define the lower storey frame. The floor joists 25 can then be lifted into position and bolted or otherwise fastened to the studs 9 of the lower storey frame. After the floor joists 25 are connected to the studs 9 of the lower storey frame, the upper storey frame is constructed by lifting the upper storey frame modules into position on the upper plates 19 of the lower storey frame and connecting the load-bearing studs 33 of the upper storey frame onto the upper plates 19 of the lower floor frame, while ensuring that the studs 33 are vertically-aligned with the studs 9 of the lower storey frame . The same procedure can be used to construct successive floors of the building.
Many modifications may be made to the embodiment of the steel frame of the invention shown in the Figure without departing from the spirit and scope of the
invention .
By way of example, whilst the embodiment includes the load-bearing studs 9 of the lower storey frame
extending all of the way into the floor cavity 13 and being connected to the upper plates 19 and the upper chord members 23, the present invention is not confined to this arrangement and in some situations where the floor frame is sufficiently stable structurally, the load-bearing studs 9 of the lower storey frame may extend part way only into the floor cavity 13 and be connected only to the lower chord members 17 and the lower chord members 21 only.
