Abstract
A metal stud 1 for spacing apart the skins 11, 12 of a partition comprises a pair of flanges 3, 4 spaced apart by a web 2 which includes, along its whole length, a section of expanded metal thus reducing the amount of metal which has to be used in the stud and reducing heat transfer by conduction from one flange to the other. To make the stud, the central portion of a metal strip is expanded and then the edge strips are bent to form the flanges 3, 4. <IMAGE>
Description
SPECIFICATION
Partition Stud
The present invention relates to partitions of the type comprising a pair of outer skins internally supported by structural strengthening studs. More particularly, the invention relates to the formation of the studs.
Partitions of the type referred to above are well known and are produced in many forms with the skins comprising plaster-board, chip-board, steel backed plaster-board etc. In order to space the two skins apart from one another and to provide a degree of strengthening to the skins it is known to provide studs between the skins, the studs comprising various materials; and, particularly when using steel backed plaster-board for the skins, metal studs are frequently used. These may comprise a standard I-sectioned member, the respective skins being fixed to the outer chords of the member by, for example self-tapping screws, to support and provide suitable spacing between them.It will be appreciated that a not inconsiderable amount of metal must be used in a partition panel incorporating such studs and, furthermore, because of the solid nature of the studs significant heat transfer between the two skins may take place, particularly in the case of a fire on one side of the partition.
It would be desirable to reduce both the amount of metal used and the heat transfer through such studs.
Therefore, in accordance with the present invention a metal stud for use in spacing apart the skins of a partition comprises a pair of chords, spaced apart by a web which includes, along its whole length, a section of expanded metal.
Expanded metal is well known and comprises a metal sheet which has been slit or sheared to produce a number of closely spaced slits which are then expanded into diamond or other shaped apertures by pulling apart the edges of the sheet.
By i#ncorporating a section of expanded metal in the web, for the same given width of the stud between the chords as in a conventional Isectioned stud, the weight of metal used can be significantly reduced and valuable material can be saved. Furthermore, the reduction in material will also help to reduce heat transfer as the conduction paths for heat from one chord to the other comprise merely a plurality of strands between the opened apertures in the expanded metal rather than a full solid sheet.
Preferably, the expanded metal section will extend across substantially the full width of the web and will comprise a series of rows of apertures on either side of a central strip, the strands between the apertures extending in herring-bone fashion from the central strip.
Preferably, the stud will comprise a single member integrally formed from a metal sheet, the chords being formed by unexpanded edge portions of the sheet bent out of the plane of the sheet so as to provide the stud with a substantially I-sectioned shape.
In accordance with the second aspect of the invention a metal stud for a partition is formed by forming an expanded metal portion in a metal strip and thereafter bending unexpanded edge portions of the strip out of the plane of the strip to form a pair of chords, spaced apart by a web comprising the expanded metal portion.
Two examples of a stud according to the present invention will now be described with reference to the accompanying drawings in which:~
Figure 1 A comprises a side elevation and
Figure 1 B a cross-section through a first stud and partition; and,
Figure 2A comprises a side elevation and
Figure 2B a cross-section of a second stud.
The stud 1 shown in Figures 1 A and 1 B is substantially I-shaped in cross-section, comprising a central web 2 and a pair of chords 3, 4. The stud
1 is formed as an integral member from sheet steel of .475mm thickness, tight coat galvanised to BS2989, the central portion of the web being slit in a conventional slitting machine and expanded through a series of pinch rollers to the form shown in Figure 1 A, so that the central portion of the web 2 comprises four rows of apertures 5 (dimensions 7 xl Omm), two arranged on either side of a central strip 6 with their respective strands 7 and 8 disposed in herringbone fashion. On either side of the web 2 a pair of connecting portions 9 are bent out of the plane of the web by a series of profiled rollers, simultaneously with the expansion of the web 2, joining with the chords 3, 4 at one edge of each chord.The opposite edge of each chord is formed with a strengthening flange 10.
The chords 3, 4 support respective skins 11, 12 of a partition, the skins being of conventional plaster-board, chipboard or other sheet material as known in the building industry and attached for example by self tapping screws (not shown) to the chords 3, 4.
It will be appreciated, by looking at the side elevation in Figure 1 A, that the overall width of the web 2 has been considerably increased by the expansion process. Before expansion the nowexpanded portion would have occupied only the width of two of the strands on either side of the central strip 4, whereas the same portion when expanded comprises substantially the length of two of the strands on either side of the central strip. The increase in width of the web 2 has a corresponding reduction in material over that used for an equivalent I-sectioned stud having a plain, unexpanded web, and thereby considerably reduces the weight of the stud. At the same time, the full length of the web 2 is not available for conduction of heat, the heat having to pass through individual strands 7 and 8, and conduction thereby being reduced between the two chords.
The stud shown in Figures 2 is similar to that of
Figure 1, but the connecting portions 9 both extend from the same side of the web 2 and, furthermore, are closed up against the adjacent chord 3, 4. This construction may stiffen the sides of the stud somewhat. However, the other features of the stud shown in Figure 2 are substantially the same as that of Figure 1 and do not need to be described in detail.
Claims (8)
1. A metal stud for use in spacing apart the skins of a partition, comprising a pair of chords, spaced apart by a web which includes, along its whole length, a section of expanded metal.
2. A metal stud according to claim 1, wherein the expanded metal section extends across substantially the full width of the web.
3. A metal stud according to claim 1 or claim 2, wherein the expanded metal section comprises a series of rows of apertures on either side of a central strip, the strands between the apertures extending in herring bone fashion from the central strip.
4. A metal stud according to any of claims 1 to 3, which comprises a single member integrally formed from a metal sheet, the chords being formed by unexpanded edge portions of the sheet bent out of the plane of the sheet so as to provide the stud with a substantially I-sectioned shape.
5. A metal stud according to claim 1, substantially as described with reference to the accompanying drawings.
6. A method of forming a metal stud for a partition, the method comprising forming an expanded metal portion in a metal strip and thereafter bending unexpanded edge portions of the strip out of the plane of the strip to form a pair of chords, spaced apart by a web comprising the expanded metal portion.
7. A method according to claim 6, wherein the expanded metal portion is first slit and thereafter passed through a series of pinch rollers to expand it.
8. A method according to claim 6 or claim 7, wherein the chords are bent out of the plane of the web by being passed through a series of profiled rollers.
