A.ss for A D D E SS FO R SE Invetion T ite: AEt De Tails of Associated Provisional Applications: NOs: I The following statement is a full description of this invention, incl"~l best method of performing it known to me:- This invention relates generally to building structures and relates in particular to a building structure with a central load-bearing column for supporting a roof canopy and a floor or floors suspended below the roof canopy, The invention in one respect provides a building structural unit or module including a central, load-bearing column adapted, when in use, to be positioned vertically with one end thereof at or below ground, the other end of the column adapted to be attached to and support a roof structure above the ground, said unit or module further including a plurality of vertically aligned elongate tensioning and stabilizing members, one end of each of said elongate tensioning and stabilizing members are adapted to be attached underneath the periphery of the roof structure, the other ends of which are adapted to be anchored at or below ground level to maintain the column in correct vertical attitude.
More particularly and preferably, the central column is provided with a base plate which is adapted to be bolted upon a performed concrete or reinforced et...
concrete base pad and is provided with at least one flange forming a support and S attachment points for said roof structure.
pr Preferably, or more particularly, the column is provided on its upper part with at least one horizontal, circumferential flange as a support and providing attachment points for trusses of said roof structure and is provided with intermediate vertical, circumferentially spaced flanges for attachment and support of floor supporting joists, beams or the like.
V .9 Preferably, said roof structure is constructed as a pre-assembly unit of a plurality of steel trusses joined to form a central vertical socket portion which when oriented in an assembly attitude is adapted to be suspended upon the loadsupporting column and fixed onto supportive fixing means on the column by bolting or welding or the like means of attachment.
The invention further provides a method of building a building structural unit or module comprising placing vertically upon the ground or upon a preformed structural base at ground level, ene end of a central, load-bearing column, the other end of the column having roof structure fixture means provided thereon and being adapted to support a roof structure, canopy or the like above the ground, stabilizing or tensioning members such as steel cables, rods, pipes or the like then being attached under the roof and to anchor means in the ground in vertical alignment with the periphery of the roof structure.
According to one alternative of a specific method of construction falling within the general concept of the foregoing method, the column is placed upon a pad of concrete or other suitable material at the bottom of a prepared excavation I hole of larger diameter than the column and wherein after installation of the
I
column, any void between the column and the hole perimeter is filled with concrete to maintain the column in a vertical position.
Preferably, in the above described method at least the roof structure is constructed as pre-assembled unit comprising a plurality of trusses including truss frame members formed into a vertical, central female socket portion so that when Q 71 C Ir W 3 the roof structure is lifted up from ground level as a unitary structure by erection means such as an extendible boom crane and then over and then lowered down upon a circumferential flange adjacent the upper end of the erected column the pre-assembled unit is fixed onto the column by fastening means bridging the column and roof frame socket portion.
Throughout this specification the term "load-bearing" means that all loads subject to gravity are borne by the load-bearing column and includes both dead loads and live loads. Dead loads being the weight of the roof structure including roof frame, roof covering, ceiling and where there is more than one or ground floor the weight of the floor and bearers, the walls, doors, windows, wall linings external and internal, internal fitting. fixtures and furniture. Live loads being a o 0** a 0* 0* a

Figure 2 is a vertical sectional partial view on an enlarged scale of the upper portion of the column and inner roof frame structure of the embodiment of Figure 1.
Figure 3 is a plan view of a tie plate for attachment of roof frame trusses to the support column in accordance with the invention.
Figure 4 is a vertical, sectional partial view on an enlarged scale of the mid suspended floor portion of the column of the embodiment of Figure 1.
Figure 5 is a cross section of the portion of the column shown in Figure 4.
Figure 6 is a vertical sectional partial view of the bottom of the column of Figures 2 and 4 of the drawings.
Figures 7 and 8 are sequential diagrams of steps in a preferred method of erection of the building structure in accordance with the invention.
Referring to the drawings there is generally shown a building structural unit or module which is constructed generally in the form of a central, loadbearing column, cylindrical or other shape in cross-section, 10 which may be variable in cross-sectional geometry thus it can be square or 10 circular and selected from various materials of 0*0 S.o" construction such as reinforced or pre-stressed concrete or a slotted or unslotted pole of plain or laminated wood but in this particular example the column is in the form S' of a circular tubular stanchion of structural steel having an apertured steel base plate 11 welded thereto to enable it to be bolted to threaded bolts previously o embedded into pre-formed load-bearing base pad 12 of reinforced concrete. After the stanchion (wooden post or the like, with base plate 11) has been fixed vertically in place upon the structural base 12, a canopy-like roof 13 is fabricated on site while on temporary supports 13a and 13b and is then socketed onto and then fixed to the stanchion by means of a fixing member.
Referring in general to Figures 7 and 8 of the drawings which show one erection technique which may be preferred, after pouring of the pad of reinforced concrete and fixing of bolts therein and hardening or curing of the concrete, the column or stanchion 10 is lifted up vertically by suitable erection means such as a 6 mobile, extensible boom crane, temporary supports 10a and lOb are positioned in place against the column 10, and the base plate 11 of the column is fixed to the pad, the roof is pre-assembled on the ground either in situ or prefabricated in a factory or the like and brought to the site then lifted up above and centred over the pre-erected stanchion by suitable mechanical means such as a mobile extensible boom crane and is lowered over the stanchion with the socket centrally placed over and 10 installed on top of the stanchion to be supported by the *e stanchion 10 and the tie piece is bolted both to the truss members and to the apertured internal top flange of the sitanchion and the bottom of the truss members is bolted to flange 23.
The roof preferably, comprises a pitched or sloping structure of a plurality of trusses formed by joined members of structural material comprising vertical members such as the two shown and labelled 14, 15 forming &Sol a socket for fitment upon the column, horizontal bearers 16, 16a inclined rafters 17, 18 and diagonal struts 19, 20. A roof covering is denoted by reference numeral 21 and can be any material suitable for roofing such as steel or aluminium sheets, for example corrugated steel sheeting or galvanised steel, asphaltic shingles, tiles or the like.
In more detail, the structure for fixing the roof frame members to the top of the column or stanchion is shown more clearly in Figure 2 of the drawings wherein the column is provided with an apertured, upper and inwardly-facing load-bearing support flange 22 and an apertured, lower and outwardly-facing support flange 23 to which are bolted upper and lower and apertured portions of eight trusses such as the two shown in Figure 1 and labelled 24 and 25. Referring to Figures 2 and 3 of the drawings, a dished, top truss chord ring 26 has a central annular portion or collar 27 provided with circumferential bolt holes such as the one labelled 28 and a plurality of inclined radial arms such as the one labelled 29 the arms also being provided with bolt holes such as those labelled 30, 31 which align with those of S. the truss top chords such as the one labelled 17. The top truss chord ring 26 bridges the top of the column and top truss chords 17, 18 and is bolted both to the column and to each top truss by nut and bolt sets such as those labelled 32, 33. The bottoms of the radially inwardly-facing truss members 16, 16a are bolted to the lower peripheral and cutwardly-facing supporting flange 23. A floor 34 is constructed of steel floor beams 36 which are attached both to the vertical fins 37, 38 having fixing holes such as those labelled 37a and 38a are affixed to or formed as part of the central column or stanchion 10 as shown on Figures 4 and 5. A plurality of elongate, vertical tensioning and stabilizing members such as the cables, rods or pipes labelled 39, 40 are attached to the roof eaves and to the suspended floor 34 and are anchored into earth anchors 41, 42. One of the functions of these tensioning and stablizing members is to maintain the column in a vertical position. Walls 8 such as the external walls labelled 43, 44 are fixed to the outside of the structure between the roof and the suspended floor and ceilings 45, 46 are installed. A ground level floor 47 is installed at ground level if required.
Alternatively, the column may be placed upon a pad of concrete or other suitable material at the bottom of a prepared excavated hole of larger diameter than the column and then after installation of the column, any 10 void left between the column and the hole perimeter is .6 6.4" filled with concrete to maintain the column in a vertical position.
Alternatively, the truss chord members may be pre-assenbled by attaching one end of each to cleats welded to column 10. After mounting the column in the vertical mode, the truss chord members are lifted and bolted together at the outer ends, forming a complete triangular truss structure.
.Alternatively, the load-bearing column may be of cylindrical or other shape in cross-section, and may be solid or hollow.
