Complete Specification for the invention entitled: P000 57 0 Q 8Cp000057"A METHOD OF BUILDING STRUCTURES" The following statement is a full description of this invention, including the oest method of performing it known to me:- -1Iv--2 THIS INVENTION relates to the erection of buildings. In particular the invention relates to a method of erection buildings to increase the height thereof and facilitate the erection of a ro ,f structure on the ground or at a relatively low height.

In one form the invention resides in a method of building construction comprising erecting a roof structure, fixing a plurality of first columns to one side of the roof structure at spaced locations therealong, wherein said first columns are pivotally mounted to the roof structure about a substantially horizontal pivot axis to extend inwardly from the pivot axis, causing pivotal movement of the first columns with respect to the roof structure towards a raised position at which position the first columns are located substantially below the pivot axis, locking the first columns in the raised position, pivotally mounting a set of second columns to the other side of the roof structure at spaced locations therealong wherein said second columns are pivotable about a substantially horizontal second pivot axis causing pivotal movement of the second columns towards a raised

S

position at which the second columns are located substantially below the second pivot axis and locking the second columns in the raised position.

The invention will be more fully understood in the light of the following description of one specific embodiment.

The description is made with reference to the accompanying Idrawings of which:- Figure 1 is a schematic view of a roof in the unerected position; Figure 2 is a schematic view of a roof in the first stage of erection; Lit FT N.

-3 Figure 3 is a schematic elevation of a roof according to the embodiment showing the first strut in the raised position sh-wing the mounting of a second strut; and Figure 4 is a schematic elevation of the embodiment showing the first and second struts in the raised position.

The embodiment is directed to erection of a building incorporating a roof structure of any desired form. The difficulty with buildings having conventional roof structures arises from the limitations of the free space available below the truss structure. It is an object of a -the embodiment to provide a method whereby the height of S such structures can be increased. The embodiment as shown 0-0 in the drawings comprises a roof structure of conventional form which is erected in position on fixed columns 12. If desired the columns may be shorter than usual to facilitate construction of the roof structure at or close to ground level. On completion of the erection of the roof a plurality of first columns 14 are pivotally mounted at one end along one side of the roof structure, at the junctions of the fixed columns 12 with the roof structure, for pivotal movement about a transverse horizontal pivot S axis 13 thereof. The first columns 14 are mounted to extend inwardly from the one side of the pivot axis 13. A tensioning means is then installed between the lower end 000 of the fixed columns 12 and the lower end of the respective first columns 14. The tensioning means may take the form of a winch, a block and tackle, or a mechanical or hydraulic jack or like means. Activation of the tensioning means to shorten the distance between the lower end of the fixed column and the first column causes pivotal movement of the first columns about the pivot axis 13 to raise the one side of the roof structure. To ensure 4 against collapse of the structure in the event of the failure of the tensioning mean prior to fixing a safety tie 16 is provided between the first columns 14 and the fixed columns 12 or roof structure 11 which will decrease in length in accordance with the increase in height of the roof structure.

If desired the tensioning means as described above can be applied between the free ends of the first column 14 and fixed ground anchors in addition to, or as alternatives to, the tensioning means previously described.

Once the first columns 14 are raised to a position at e which they substantially underlie the pivot axis they are s then lockingly engaged with the respective fixed column 12 and a set of second columns of similar form to the first columns 14 are mounted at spaced locations along the other o side of the roof structure to be pivoted in a similar S manner to raise the roof structure.

o It should be appreciated that the first and second columns 14 may take any desired form to provide a load supporting o column for the roof structure. In addition if desired the raising operation effected by the first and second columns as described above may be repeated by mounting a further set of columns to the lower end of the first set of first and second columns and causing corresponding pivotal movement of the further set of columns to raise the roof structure and repeating the exercise until the building has achieved the required height.

It should be appreciated that the scope of the present invention need not be limited to the particular scope of the embodiment described above. In particular the embodiment has application to any form of roof structure.

Claims

1. A method of building a construction comprising creating a roof structure fixing a plurality of first columns to one side of the roof structure at spaced locations therealong wherein said first columns are pivotally mounted to the roof structure about a substantially horizontal pivot axis to extend inwardly from the pivot axis, causing pivotal movement of the first columns with respect to the roof structure towards a raised position at which the first column is located substantially below the pivot axis locking the first columns in the raised position, pivotally mounting a set of second columns to the other side of the roof structure a at spaced locations therealong wherein said second columns are pivotable about a substantially horizontal second 9 pivot axis causing pivotable movement of the second columns towards a raised position at which the second **gill columns are located substantially below the second pivot axis and locking the second columns in the raised position.

2. A method as claimed at claim 1 wherein means for causing pivotable movement of the first and second columns comprises a tensioning means between a fixed point to the respective side of the building and a point on the first or second column spaced from the pivot axis said tensioning means being capable of reducing its length.

3. A method as claimed at any one of the preceding claims wherein a fixed column is mounted to the roof structure at said spaced locations to support the roof structure and said first and second columns are lockingly engaged with the respective fixed column when in their raised positions. -6

4. A method as claimed at claim 3 as dependant on claim 3 wherein the fixed columns comprise said fixed If points.

A nmethod as claimed at any one of the preceding claims wherein additional first and second columns are fixed to the lower ends of the first set of first and second columns when the latter are in their raised positions said additionalfirst and second columns being pivotable about a second horizontal pivot axes at said lower ends said method comprising causing pivotable movement of the first columns and then the second columns to cause them to be moved to a raised position substantially below the respective pivot axes and locking the additional first and second columns in their raised Q Co position. :9

6. A method of building substantially as herein described.

7. A construction built according to the method as claimed at any one of claims 1 to 6. DATED this SEVENTH day of JUNE 1990. LEWIS RONALD HARDING Applicant. Wray Associates, Perth, Western Australia, Patent Attorneys for Applicant. A )NT 0
