AU740788B3 - Re-usable zinc-alume shed as cover for extended building time of concrete house - Google Patents

Description

This final application for a Petty Patent follows provisional application PQ6849 of the 13th. of April,2000. The petty patent application involves the use of a pre-fabricated zinc-alume shed as a Tempory enclosure or cover for a internal all concrete building. The all concrete building takes a considerable amount of time whereas the Zinc-Alume shed can go up within a day. The Zinc-Alume shed can be taken down with each piece marked for position and orientation and re-erected on another site for another concrete building. Basically the concrete slab on the ground is slightly larger than the concrete building but is of sufficient size for the Zinc- Alume shed to enclose and also concrete building or house when exposed (zinc-alume shed taken away) has a protruding portion of slab. The main problem with concrete buildings with wall systems described in applications 69,983/91 of the 25/1/91 and 15,179/97 the 10/3/97 and 50,082/99 of the 23/9/99 all by this inventor is that starter bars (12mm. diameter bar) coming out of the floor makes it difficult to smooth concrete during pouring operation.

To make pouring and smoothing off easier it is neccessary to introduce steel strip, preferably 20mm. by 3mm. with the 20mm. side bevertical and supported by a 12mm. (about 12mm.) diameter rod which penetrates ground and substrate that slab is to go on. So a series of parallel strips of these supported 20mm. by 3mm. strips such that top edge is surface level of slab with parallel strips up to Ix meter apart to make smoothing of poured concrete (during alot easier. Figure la shows a cross-section of the slab with 1 the ground the slab is on with 2 the fine sand layer over this (about 50mm. thick) with 4 the moisture proofing plastic film over sand layer with plastic chairs 3 over plastic film with chair 3 supporting re-inforcement mesh 8 to which bar starters 7 are 2 welded to 7a (welded to re-inforcement mesh 3) and protrude out of slab and anchor wall frames of 69,983/91 when concrete is poured.

The thin vertical steel strip 5a is welded 5c to rod (about 12mm.

diameter) 5b which is pushed through plastic film and sand layer into ground and the top edge of strip makes it easier to level concrete off during pouring. Figure lb shows the plain view of the slab when finished with parallel strip edges 5a exposed on surface of slab 6 with starter bars 7 marking the profile of where the concrete wall is to go. Surface of concrete slab can be rendered by tough cement plaster with rubberizing compound added to help adhesion and increase flexability of increased cement powder plaster as slab flexes and bends slightly over time. So with the improved means of doing slabs with numerous starter bars protruding from slab it means that the property security of doing frames (69,983/91) within a Zinc-Alume shed means building can be assembled on site over a period of time with better security against theft than a open building site, giving protection against weather as well as not being a unsightly unfinished building during a slow construction schedule which is hampered by financial restraints.

The size of the Zinc-Alume shed is a 7.5 meter by 9.0 meters prefabricated shed that can be purchased off any of a number of prefabricated shed manufacturers and the concrete building planned for a proposed development site is 7.0 meters by 8.5 meters fitting easily within pre-fabricated shed with no horizontal rafters so working near the top of concrete building's wall is not japered by space.

Claims (1)

1. 2. The improved method of constructing a full concrete building inside a demountable or easy to assemble or disassemble shed as claimed in claim 1 so the rows of thin steel strips welded to top of rod embedded in ground where fine edge aids in concrete leveling and allows sectioning of slab to be poured in parts over extended period if need arises.
