Abstract
The rails of e.g. a suspended ceiling grid are of I-section with the lower flange 6 wider than the upper flange 5 and are suspended by means of hangers 4 which have a bifurcated end with a transverse slot 13 which snaps over the upper flange. Holes 8 in the rails' web 7 serve both to retain the ends of cross-members of ceiling grid and to hold spring wedges 14 to clamp panels 15 against lower flange 6. <IMAGE>
Description
SPECIFICATION
Lining system
This invention relates to lining systems for buildings, both of the commervial and industrial variety.
The invention is concerned with providing lining systems for both horizontai cffind vertical structural elements, e.g. for roofs and walls. The invention is more especially concerned with providing lining systems enabling walls and roofs to achieve good fire resistance.
Lining systems of the general type with which the present invention is concerned are well known. They consist of a grid structure formed by main members and cross members, the grid being suspended from or supported by an adjacent constructional element, e.g. rafters, purlins, sheeting rails or columns. Building boards are assembled on the grid structure and retained therein by spring clips or other suitable devices.
It is an object of the present invention to provide a lining system, especially one giving good fire resistance, which is easy to assemble and install.
According to the present invention a lining system comprises a plurality of lining boards held in a grid, the grid being formed by parallel main members interconnected by cross members, the main and/or cross members being generally of Tshaped cross-section having generally parallel first and second flanges connected through an intermediate web, said boards being situated and retained in position between said first and second flanges, said grid being supported by fixing straps, each said fixing strap being of metal and having a bifurcated end adapted to snap over said first flange and retain said first flange in a transverse slot formed in the bifurcations.
Preferably the fixing straps are made of spring steel, and in a preferred embodiment the strap may have a width between 1.4 and 2.2 cm, the bifurcations being from 4 to 6 cm. long and the transverse slot having a width of 0.5 to 1.1 cm.
The bifurcations may be formed by simply slitting one end of the fixing strap to an extent of, for example, 4 to 6 cm. The transverse slot, which may suitably have a depth of 0.1 to 0.3 cm. may be punched out of the bicurfations.
Preferably the free end of at least one of the bifurcations is bent along an axis parallel with the width of the slot. Suitably both bifurcations are so bent, in opposite directions.
The main members and the cross members are suitably made from galvanised or similarly rustprotected cold rolled mild steel, and are rolled into their generally "T"-shaped in known manner.
Holes, e.g. square-shaped holes, are punched at spaced positions along the central web of each main and cross member to allow for easy assembly of the cross members to the main members and also to accommodate spring wedges (see below). Thus, the cross members are suitably provided with hook-shaped ends which fit into and are retained by the holes in the main members. By way of example, the main members may have individual lengths of the order of 3.6 metres, and the cross members may have individual lengths of approximately 0.6 metres.
The main members may be spaced in the grid structure slightly farther apart (centre to centre) than the nominal width of the lining boards making up the structure. This aliows for standard size boards to be used.
The lining boards are suitably held in the grid structure by spring wedges which pass through the holes in the main members mentioned above and bear on the backs of the boards. In accordance with one feature of the present invention, the spring wedges are so shaped as to be able to be used with lining boards of different thicknesses.
The main and/or cross members of the grid structure may be provided with shaped cut-outs, in addition to the holes mentioned above, to allow for expansion of the metal members under fire conditions.
The invention is illustrated in the accompanying drawings in which: Figure 1 is a perspective view of part of a grid structure suspended from a purlin, for forming a roof lining;
Figue 2 is a side view of a fixing strap;
Figure 3 shows the fixing strap being snapped on to a main grid member;
Figure 4 is an end view of a main grid member supported by a fixing strap;
Figure 5 shows the method of retaining lining boards on a main grid member by means of a spring wedge;
Figure 6 is a view similar to that of Figure 5, but showing the use of a modified spring wedge; and
Figure 7 is a perspective view of part of a grid structure supported on a sheeting rail, for forming a wall lining.
With reference to the drawings, the grid structure shown in Figure 1 consists of a plurality of interconnected main members 1 and cross members 2, the main members 1 being suspended from a roof purlin 3 by means of fixing straps 4. The main and cross members 1, 2 respectively are generally of T-shape, as may be seen more clearly in Figures 3 to 6, and comprise an upper flange 5 and a lower flange 6 interconnected by a web 7. The main and cross members 1, 2 respectively are suitably formed from galvanised mild steel, for example of thickness 0.55 millimetres, and rolled into Tshape in known manner.
If the grid structure is to be used with lining boards of nominal width 600 millimetres, then the main members 1 are suitably spaced at, say, 603 millimetres centre to centre, to allow for small variations in the width of the boards as supplied. The cross members 2 are provided with hook-shaped ends (not shown) which pass through and are retained by square-shaped holes 8 punched out of the webs 7 of the main members 1. The holes 8 are suitably spaced at 100 to 200 e.g. 150 millimetres centres. The web 7 of each individual main member making up the grid is also explained with an expansion hole 9, which allows for expansion of the system under fire conditions, so that if the lining boards used in the system of the invention are fire-resistant boards, a completely fire-resistant system results.
An important feature of the invention is the fixing strap 4. This is provided at one end with a longitudinal slit 10 providing two bifurcations 11, 12. A transverse slot 13 is cut or punched from the bifurcations 11, 12 and has a width just slightly in excess of the width of the flange 5 of the main grid members.
The free end of the bifurcation 11 is bent, as
best seen in Figure 2 and 3, to assist the
assembly of the strap on the main grid member.
The strap may be attached to the main grid
member 1 in very simple manner. It is first placed on the top flange 5 of the main grid member so that the bifurcations 11, 1 2 contact opposite edges of the flange 5. Downward pressure of the strap on the flange cause the bifurcations to splay outwardly, as illustrated in Figure 3, and when the transverse slot 13 reaches the flange 5 the strap 4 turns about a right angle to assume the position illustrated in Figure 4. (Removal of the strap 4 from the main grid member 1 maybe accomplished by simply turning the strap 4 through a right angle and pulling it away from the
grid member). The free end of the strap 4 may be attached to the purlin 3 in a conventional manner.
Lining boards (not shown) are then placed in position on the lower flanges 6, and are held tightly in position by means of spring wedges 14 which pass through holes 8 and bear downwardly upon the lining boards 15. The use of a modified spring wedge 16 (see Figure 6), having an upwardly joggled lower limb 17 enables lining boards of differnt thicknesses (e.g. 6 millimetre
and 9 millimetre boards) to be used.
The lining boards themselves may be any
commercially available building board. For
example, the lining board may be a plaster board,
but it is preferably a fire-resistant board such as
those sold under the Trade Names "Supalux" and
"Masterboard".
Figures 1 to 6 of the drawings illustrate the use
of the invention in a roof lining system. The use
of the invention in a wall lining system is illustrated in Figure 7. Broadly speaking, the wall
lining system is similar in all respects to the roof lining system, except that it is attached to spaced sheeting rails rather than purlins.
Thus, referring to Figure 7, the grid structure consists of interconnected main and cross members 21 and 22 respectively, constructed and assembled in identical manner to the members 1 and 2 respectively of Figures 1 to 6.
The grid structure is supported on horizontal sheeting rails 23, forming the shell of the wall, by means of fixing straps 23, identical in form and manner of attachment to main members 21 to fixing straps 4 of Figures 1 to 4.
A wall lining system is built up by constructing
a grid structure from main members 21 and cross members 22, placing lining boards between the flanges 25 and 26 of the main members and
holding them there by means of spring wedges
14, snapping fixing straps 24 over the flanges 25 of the main grid members 21, and then hanging the fixing 9traps 24 over the sheeting rails 23, as shown in Figure 7, the free ends of the fixing straps 24 being bent as required.
