4 The web part may comprise metal plate.
The edge pieces may comprise rolled metal sections The invention will now be described by way as an example only with reference to the accompanying drawings, wherein; Figure I shows an apparatus for manufacturing a structural element by means of a method according to the first aspect of the invention, and Figure 2 is a plan view of the apparatus of Figure 1.
Figure 3 is a side view of a structural element embodying the invention.
Referring now to Figure 1, a structural element 10 according to the second aspect of the invention is shown in an apparatus 14. The structural element 10 comprises a pair of end pieces 11, each of said end pieces comprising a metal element generally "T"-shaped in cross section having a projecting part 12a and a limb 12b. Said end pieces 11 are disposed such that the projecting part 12a of each said piece I I is directed towards and aligned with the corresponding projecting part 12a of the other edge piece 11, i.e. such that the projecting parts 12a are generally mutually co-planar. Connected between the projecting parts 12a is a web part 13, opposite the edge regions of the web part being attached to the projecting parts 12a.
Although the edge pieces shown herein are "T"-shaped in cross-section, the limb and projecting part need not be perpendicular, and any suitable crosssection may be used as desired, for example an "L"-shaped or "Y"shaped cross-section.
As shown in the Figures, the apparatus 14 comprises a first part 15 and a second part 16 of known and conventional type. The first part 15 comprises a support 17 on which is mounted holding means in the form of a jig 18 (not shown in Figure 2). The jig 18 is provided with a first clamp 19a and a second clamp 19b. Each clamp 19a, l9b is operable to engage a limb 21b of an edge part I I and comprises a clamp 20 vertically movable on a post 21 such that the clamp means 19a, l9b can accommodate edge pieces 11 of varying dimensions.
The clamp means 19a is fixed relative to the support 17, while the clamp means 19b is movable relative to the support 17 by an actuating means 22 in a direction towards and away from the clamp means 19a.
A plurality of pairs of clamp means 19a, l9b may be provided to clamp said edge pieces 11 at a plurality of longitudinally separated positions, such that the relative spacing and orientation of the edge pieces I I may be varied. Where such a plurality of pairs of clamp means is provided, the clamp means l9b may be moveable relative to the clamp means 19a by one or more linked actuating means. Alternatively, the clamps means l9b may be moved by separate actuating means, or a plurality of groups of clamp means l9b may be provided, each group being mutually linked, and movable by one or more actuating means per group.
The actuating means 22 may comprise a fluid operated ram, or may comprise an electrical operating means such as a solenoid or motor, or any other suitable mechanism as desired.
The second part 16 comprises an upright 30 with a transverse element 31 mounted thereon. The transverse element 31 extends above the first part 15, in a direction transverse to the support 17, and is movable in a direction longitudinally of the support means 17 on tracks 40 only shown in Figure 2.
Mounted on the transverse part 3) I are a pair of arms 32, each of which is provided at one end with a welding head -3)3. The arms 32 are mounted on carriers 34 disposed on the transverse element 31 such that the arms 32 are able to move along the transverse part 311. The arms 32 are also be movable in a generally vertical direction to vary the vertical disposition of the welding heads 33 relative to the first part 15.
As seen in Figure 2, in the present example a cutter 41, shown diagrammatically in Figure 2, is provided disposed on the opposite side of the first part 15 to the second part 16. The cutter is movable in a direction generally parallel to the support means 17 on tracks 42 only shown in Figure 2.
6 In Figure 2, a pair of longitudinally spaced support means 17 are shown, although of course one or a plurality of such support means may be provided.
To manufacture a structural element 10, a pair of edge pieces I I are provided. The edge pieces I I may each comprise 'T'-shaped rolled sections, conventionally referred to as 'structural Ts', or may be provided by cutting a universal beam or universal column to provide at least one edge piece.
A universal beam or universal column may be cut by for example sawing, gas cutting, plasma cutting or laser cutting. The shape and dimensions of the edge pieces 11 may be selected according to the desired shape of the structural element 10. The projecting part 12a of each edge piece 11 may have an edge which is substantially parallel to the limb 12b or inclined relative thereto. XVhere one or more of the edge pieces I I is provided by cutting a universal beam or universal column, the universal beam or universal column may be cut by one or more cuts to provide a structural T of the desired configuration. The edge pieces 11 may each be of the same cross section or may be of differing cross section, depending whether a structural element comprising a symmetric beam or an asymmetric beam is desired.
Where the edge pieces are of other than "T"-shaped they may be provided by cutting an appropriately shaped section. For example, a channel section beam may be cut along its web to provide two "L"-shape end pieces.
One edge piece I I is mounted on the jig means 18 by engaging the limb 12b of the edge piece 11 by the clamp means 19a. Similarly, a further edge piece 11 is engaged with the clamp means 19b. The position of the clamp 20 of the clamp means 19a, 19b is varied to accommodate each edge piece 11. The edge pieces I I are mounted in the jig means 18 such that the projecting parts 12a of each edge piece I I are directed mutually inwardly and are generally mutually coplanar. The spacing and relative orientation of the edge pieces I I is varied by operating the actuating means 22 to move the clamp means 19b relative to the clamp means l9a to provide the desired spacing. Where it is 7 desired that the edge pieces I I are not generally parallel and a plurality of clamp means l9b are provided, the plurality of clamp means l9b may be disposed using respective actuating means 22 such that the edge pieces I I are inclined relative to one another.
A web part 13 is cut to a desired shape prior to introduction between the edge piece 11. The web part may be cut by sawing, gas cutting, plasma cutting or laser cutting, and the cutting may be performed by the cutter 4 1. The web part 13 is then located between the projecting parts 12a and is welded thereto. During the step of welding, the web part 13 is supported on a suitable support comprising a block 23 of appropriate height. The block 23 may be provided with a layer of copper or other suitable material in its upper surface to facilitate welding. It may be envisaged that other support means may be used as desired. The actuating means 22 is operated during welding to urge the clamp means l9b towards the clamp means 19,a to ensure good contact between the abutting edges of the edge parts I I and the web part 13.
The web part 13 may extend along the whole or part of the length of the edge parts 11 and may be continuous or discontinuous. The welding may be manual, stick welding, submerged arc welding or laser welding, and the welds may be continuous or discontinuous.
Where the apparatus of Figure I is used, the welding step may be performed using the apparatus shown, the spacing of the welding heads 33 being varied by movement of the carriages 34, and the arms 32, by suitable means such as a cable drive. The welding heads 33 are moved longitudinally of the structural element by means of a motor driven pinion carried by the upright 30 engaged with a floor mounted rack, not shown, such that the welding heads 33 follow the line of the desired welded join. The web part 13 may have a thickness equal to one, both, or neither of the projecting means pails 12a.
Openings 50 are formed in the web part 13 and/or at least in one of the edge pieces and/or at least one of said limbs as desired. The openings may be 8 formed by cutting or punching or other means, either before or after connection of the web piece to the edge pieces. In the present example the openings 50 are cut by the cutter 4 1, and may be cut by sawing, gas putting, plasma cutting or laser cutting. The openings may be circular, rectangular, oval, elliptical, obround, polygonal or irregular. The openings may be at regular or irregular intervals. An opening may be cut which extends in at least two of, the web parts projecting parts, limbs.
The cutter is moved transversely and longitudinally by analogous means to those described hereinbefore in respect of the welding means.
It will be apparent that any desired configuration of a structural element comprising a cellular beam may be provided using this highly flexible method, which permits a much wider range of opening height, width and geometrical shapes in the cellular beam than was previously achievable.
The size and distribution of the openings may be selected according to the desired use of the beam, and may for example permit the passage of building services. Where passages for building services are provided, this reduces the need for building services to pass below the structural element and permits a decrease in the floor depth of a structure comprising such a structural element.
The combination of rolled metal section and metal plate is particularly advantageous because it permits of a wider range of beam depths, and opening sizes and distribution than hitherto was possible. In particular, the thickness of the web part may be selected as desired to optimise the desired characteristics of the structural element, and is not limited to the thickness of standard rolled structural Ts, columns or beams as before.
It will be apparent that although a particular apparatus is described herein, such a method may be performed using any other desirable apparatus, or indeed may be performed entirely manually. Where a suitable apparatus is 9 provided, it would be possible to provide suitable computer control means to control the various parts of the apparatus.
Although in the example described hereinbefore a single edge piece has been connected to an edge region of the web and another single edge piece has been connected to the opposite edge region of the web, if desired at least two edge pieces may be connected to one edge region of the web and at least another two edge pieces may be connected to the opposite edge region of the web.
Where a single edge piece is so connected it may be connected in edge to edge relationship with the web.
When at least two edge pieces are so connected one may be connected in face to face relationship with opposite faces of the edge region of the web. For example when each edge piece is of "L"-shape in cross-section they will together form a "T"-shape.
Such a single or at least two edge pieces connected to an edge region of the web may extend along the whole length of the structural member or only over a part thereof The remainder of the shoulder member may have an another edge piece or edge pieces connected thereto. In all these cases there will be at least one longitudinal position at which the single or at least two edge peices are connected to an edge region of the web.
If desired instead of connecting by welding as described above the web part may be connected to the edge pieces by bolting, adhering or other means.
In the present specification "comprise" means "includes or consists of' and "comprising" means "including or consisting of'.
