Detailed Description
Referring to the drawings there is illustrated a framing system comprising a number of frame elements typically of metal, in this case rolled steel sections.
The framing system comprises a plurality of laterally spaced-apart studs 1 or uprights. The studs 1 are interconnected by a header 2 which extends generally horizontally. Each stud 1 comprises an elongated generally C-shaped lipped channel having a web 3 and side flanges 4, 5 which extend continuously the length of the element. The side flanges 4, 5 have inturned lips 7, 8 at the upper edge to define a generally C-shapted form. Each of the flanges 4, 5 has an elongate slot 6 therein which is typically punched out. The slot 6 is located on the central longitudinal axis of the flanges 4, 5.
The header 2 is of channel section comprising a web 10 and a pair of flanges 11, 12 which extend to embrace the web 3 and flanges 4, 5 of the studs 1 as illustrated. The header 2 is sized such that the depending flanges 11, 12 embrace the studs 1 to which it is to be secured in a relatively tight fit.
The header 2 is mounted to the studs 1 in such a way as to accommodate limited vertical movement of the header 2 relative to the studs 1. Fixings 20 are screwed through the flanges 115 12 of the header and extend to engage in the slots 6 in the stud flanges 4, 5.
The fixings 20 preferably have shallow heads in order to eliminate a bulging effect on boarding which is subsequently applied over the stud and track system. The overall shaft length will generally be a minimum length of 26mm with coarse thread. The minimum design capacity of the fixings is 2.28 fcN.
To assemble a framing system of the invention a number of vertical studs 1 are arranged with their elongate slots 6 at the uppermost ends thereof. The studs 1 are spaced-apart in accordance with the specification required. A header 2 is then placed over the studs 1 and fasteners or fixings 20 are used to secure the header 2 to the studs 1. The fixings 20 are tightened to secure the joint whilst still permitting movement of the header 2 relative to the studs 1 in response to structure settlement during construction.
In the invention the header 2 can move vertically relative to the studs 1. In this way structural parts such as walls carried by the studs 1 are isolated from stresses that may be applied to the header 2, for example from a structure 25 above the header 2 to which the header is attached by fixings 26. For flexibility in fixing it is preferred that the header flanges 11, 12 do not have fixing holes therein. In the preferred embodiment the fixings 20 may comprise self piercing rivets for connecting the header 2 to the studs 1 through the corresponding fixing regions.
Alternatively the header flanges 11, 12 may comprise fixing holes for reception of fixings. In one case such holes may comprise pilot holes in which case pop rivets may be used as fixings. In another case such holes may be sized for use with a staked fixing. In a further case the fixing hole may comprise a clearance hole for use with a self tapping screw.
Referring to Figs. 11 and 12 there is illustrated another framing system according to the invention which is similar to that described with reference to Figs. 1 to 10 and like parts are assigned the same reference numerals. In this case the flanges 11, 12 of the header track 2 have an indicator thereon, in this case in the form of a line 30 which extends along the length of the header 2. The marker line 30 indicates to the installer the location to which the fixings 20 should be inserted to guarantee the structure performance because of consistent fixing location.
The indicator line 30 may be provided on the header flanges 11, 12 in any suitable manner. For example, it can be applied using dedicated marking rollers or may be created using a suitable roll/marking device or printer. The line may be applied before or after roll forming of the track.
It will be appreciated that the framing system may be used in any suitable application. For example, the system may be used as a wall type frame to which cladding panels may be attached. Such as wall may be load bearing or non load bearing and may, for example, form part of a modular building point.
In the invention, there is no pre-punched hole or slot in the track 2. During the installation, the stud slot 6 is visible below the edge of the track for alignment. A fixing screw 20 is screwed into the track and passes the slot 6 of stud 1.
The screw 20 is fixed in the middle of the stud 1 which improves torsional stability.
In addition, because the slot 6 is on the centre line of stud 1, the fixing point is same for all the studs 1 regardless the stud spacing. Thus the loading capacity for the connection is consistent. Referring to Figs. 13 to 20 there is illustrated a framing system according to the invention in which parts similar to those of Figs. 1 to 12 are identified by the same reference numerals.
The framing system comprising a number of frame elements typically of metal, in this case rolled steel sections.
The framing system comprises a plurality of laterally spaced-apart studs 41 or uprights. The studs 41 are interconnected by a header 2 which extends generally horizontally.
Each stud 41 comprises an elongated generally C-shaped lipped channel having a web 3 and side flanges 4, 5 which extend continuously the length of the element. The side flanges 4, 5 have inturned lips 7, 8 at the upper edge to define a generally C-shapted form. Each of the flanges 4, 5 has an elongate slot 6 therein which is typically punched out. The slot 6 is located on the central longitudinal axis of the flanges 4, 5.
The header 2 is of channel section comprising a web 10 and a pair of flanges 11, 12 which extend to embrace the web 3 and flanges 4, 5 of the studs 41 as illustrated. The header 2 is sized such that the depending flanges 11, 12 embrace the studs 41 to which it is to be secured in a relatively tight fit.
The header 2 is mounted to the studs 41 in such a way as to accommodate limited vertical movement of the header 2 relative to the studs 1. Fixings 42 or 43 are screwed through the flanges 11, 12 of the header and extend to engage in the slots 6 in the stud flanges 4, 5.
The web 3 of a stud 41 has a pair of longitudinally extending elongate slots 40 with closed ends. The slots 40 are equi-spaced from a central longitudinal axis of the web 3. The slots 40 are typically punched out.
The system also comprises an ancillary element, such as a structural element, in this case an angle cleat 50 having a stud portion 51 and a track portion 52 which extend in use along the web 3 of the stud 41 and the web 10 of the header track 10 respectively. The stud portion 51 of the cleat 50 is attached to the web 3 of the stud 41 by fixings 42 or 43 which extend through the slots 40. Fixing screws 45 may be used to fix the header portion 52 of the cleat through the header 2 to an upper support. The fixings 42, 43 preferably have shallow heads in order to eliminate a bulging effect on boarding which is subsequently applied over the stud and track system. The overall shaft length will generally be a minimum length of 26mm with coarse thread. The minimum design capacity of the fixings is 2.28 kN.
The system of Figs. 13 to 20 is especially advantageous in that it allows the system to be readily reinforced at the joint between the studs and the header. The cleat 50 fixed to the web slots 40 increases the shear capacity of the connection. Thus the cleat 50 reinforces the joint for improved structural properties. The web slots 40 allow the cleat to be readily fitted and also facilitate any required movement between the cleat to which the header is attached and the stud 41.
In addition, in some situations an installer does not have ready access to both of the flange fixing slots 6. For example, a part (such as a structural beam) of the main structure may render access to one of the slots difficult or impossible. The cleat 50 can be fixed/anchored upwards into the head track web 10 and through to a structural substrate using suitable fixings 45. Fixings 42 or 43 may be inserted through the slots 40 in the web 3 of the stud 41 and into the stud portion 51 of the cleat 50.
In some cases the studs 41 can be directly fixed to the face of a slab/structural beam through the slots with no additional cleat or bracket.
Oversail studs would not require the slots in the oversail cleat which would reduce the cost of this component.
To assemble a framing system of the invention a number of vertical studs 41 are arranged with their elongate slots 6, 40 at the uppermost ends thereof. The studs 41 are spaced-apart in accordance with the specification required. A header 2 is then placed over the studs 41 and fasteners or fixings 42,43 are used to secure the header 2 to the studs 41. Cleats 50 may be used at some or all of the joints between the studs 41 and header 2. The fixings 42, 43 are tightened to secure the joint whilst still permitting movement of the header 2 relative to the studs 41, for example in response to structure settlement during construction.
In the invention the header 2 can move vertically relative to the studs 41. In this way structural parts such as walls carried by the studs 41 are isolated from stresses that may be applied to the header 2, for example from a structure 25 above the header 2 to which the header is attached by fixings 45.
For flexibility in fixing it is preferred that the header flanges 11, 12 do not have fixing holes therein. In the preferred embodiment the fixings 42,43 may comprise self piercing rivets for connecting the header 2 to the studs 1 through the corresponding fixing regions.
Alternatively the header flanges 11, 12 may comprise fixing holes for reception of fixings, hi one case such holes may comprise pilot holes in which case pop rivets may be used as fixings. In another case such holes may be sized for use with a staked fixing, hi a further case the fixing hole may comprise a clearance hole for use with a self tapping screw.
Similar to the version illustrated in Figs. 11 and 12 the flanges 11, 12 of the header track 2 may have an indicator thereon, such as in the form of a line which extends along the length of the header 2. The marker line indicates to the installer the location to which the fixings 20 should be inserted to guarantee the structure performance because of consistent fixing location. The indicator line may be provided on the header flanges 11, 12 in any suitable manner. For example, it can be applied using dedicated marking rollers or may be created using a suitable roll/marking device or printer. The line may be applied before or after roll forming of the track.
It will be appreciated that the framing system may be used in any suitable application. For example, the system may be used as a wall type frame to which cladding panels may be attached. Such as wall may be load bearing or non load bearing and may, for example, form part of a modular building point.
In the invention, there is no pre-punched hole or slot in the track 2. During the installation, the stud slot 6 is visible below the edge of the track for alignment. A fixing screw 42,43 is screwed into the track and passes the slots 6,40 of stud 41.
A fixing screw 42, 43 may be fixed in the middle of the stud 41 which improves torsional stability.
In addition, because the slot 6 is on the centre line of stud 1, the fixing point is same for all the studs 1 regardless the stud spacing. Thus the loading capacity for the connection is consistent. Because the slots 40 are equi-spaced from a central longitudinal axis of the web of the stud 41, the fixing points are same for all the studs 41 regardless the stud spacing. Thus the loading capacity for the connection is consistent.
The invention is not limited to the embodiments hereinbefore described which may be varied in detail.
