Abstract
A method of forming a lift shaft or similar in a multi-storey building is disclosed. The method includes the casting the shaft in segments (typically in the order of 800 mm deep) and then assembling the segments atop each other to form the shaft. The segments have vertical passages which align to form channels in which rebar can be inserted to tie the structure together.
Description
- The present application relates and claims priority to Australian Innovation Patent number 2021107156, filed 25 Aug. 2021, the entirety of which is hereby incorporated by reference.
- The present invention relates to the construction of buildings. The invention has been primarily created in relation to lift shafts, stair cores and similar inter-storey structures in multi-storey buildings, but is considered to have wider application including to the construction of columns and walls.
- In “mid-rise” (typically two to eight storey) construction there must be means to travel between storeys. Typically, this is done via lifts (elevators) or stairs. In both cases, a four-walled structure is required which extends through multiple building storeys. For convenience, the following description will refer to lift shafts, although it is equally applicable to stair cores.
- In mid-rise construction there are three methods which are commonly used to form lift shafts. The first is to lay load bearing masonry blocks in a traditional manner, then add reinforcement, and core-fill. The second is to use precast panels. The third method is to cast in situ by pouring concrete within a formwork system which includes reinforcing. The latter can include systems where the formwork forms an outer skin on the finished lift shaft, or formwork arranged to be removed to leave a concrete wall.
- There are difficulties involved with each of these methods. Block walls are slow to erect, and require skilled tradespeople. Precast panels are heavy, and require a large crane on-site. Poured concrete in finished formwork systems provide little ability to verify reinforcement and concrete condition. Removable formwork is both expensive and labour-intensive.
- The present invention seeks to propose an alternative system for the construction of lift shafts, stair cores and the like.
- According to one aspect of the present invention there is provided a method of constructing an inter-storey structure within a multi-storey building, the method including the steps of:
- pre-forming shaft segments, each shaft segment being rectangular in cross section;
- locating a first shaft segment at a required location within the multi-storey building; and
- sequentially mounting additional shaft segments atop the first shaft segment to form the inter-storey structure.
- The term ‘shaft segment’ will be understood to refer to segments of lift shafts, stair cores and other similar inter-storey structures.
- It will be appreciated that although the shaft segments have been described as being rectangular in cross section, this includes segments which have gaps in one wall, for instance to form openings into the inter-storey structure.
- It is preferred that each shaft segment has at least one vertical passage extending within a wall of the shaft segment. The passage is preferably formed by a tube cast within a wall of the shaft segment, the tube extending vertically. These passages can be aligned to form a vertically extending channel through the inter-storey structure.
- The method includes the further step of locating reinforcing rods within the vertically extending channel(s) of the inter-storey structure. The vertically extending channel(s) can then be filled with a curable substance such as a grout.
- It is preferred that the reinforcing rods are longer than the vertically extending channels. In a preferred embodiment, the reinforcing rods extend through the first shaft segment and into aligned holes beneath the first shaft segment. In the preferred embodiment the reinforcing rods also extend above the top of the inter-storey structure, providing a ‘tie point’ for a higher structure (which may be a further inter-storey structure).
- It will be appreciated that each shaft segment has four corners which are cast into position, thus providing structural integrity. This is in contrast to the use of pre-cast panels, in which the corners must be joined by a weld plate.
- It is anticipated that each shaft segment is likely to have a height in the order of 800 mm.
- According to a second aspect of the present invention there is provided a method of constructing a building wall, the method including the steps of:
- pre-forming wall segments, each wall segment being rectangular in cross section and having at least one vertical channel extending therethrough;
- locating a wall segment at a required location within the building;
- sequentially mounting additional wall segments atop the first wall segment to form the building wall;
- locating reinforcing rods within the vertically extending channel(s) of the wall segments; and
- filling the vertically extending channel(s) with a curable substance.
- According to a third aspect of the present invention there is provided a method of constructing a building column, the method including the steps of:
- pre-forming column segments, each column segment being T-shaped in cross section and having at least one vertical channel extending therethrough;
- locating a column segment at a required location within the building;
- sequentially mounting additional column segments atop the first column segment to form the building column;
- locating reinforcing rods within the vertically extending channel(s) of the column segments; and
- filling the vertically extending channel(s) with a curable substance.
- According to a fourth aspect of the present invention there is provided a method of constructing a building corner, the method including the steps of:
- pre-forming corner segments, each corner segment being L-shaped in cross section and having at least one vertical channel extending therethrough;
- locating a corner segment at a required location within the building;
- sequentially mounting additional corner segments atop the first corner segment to form the building corner;
- locating reinforcing rods within the vertically extending channel(s) of the corner segments; and
- filling the vertically extending channel(s) with a curable substance.
- It will be convenient to further describe the invention with reference to preferred embodiments of the present invention. Other embodiments are possible, and consequently the particularity of the following discussion is not to be understood as superseding the generality of the preceding description of the invention.

FIGS. 3 to 5 show alift shaft 20 formed in accordance with the present invention. Thelift shaft 20 has arear wall 22, twoside walls 24, and afront wall 26. Thefront wall 26 includes anopening 28 to serve as a doorway. - The
lift shaft 20 is formed of four segments: afirst segment 30, asecond segment 32, athird segment 34 and afourth segment 36. - The
first segment 30 is rectangular in cross section, having a height of about 800 mm. Thefirst segment 30 has arear wall 22, twoside walls 24 perpendicular to therear wall 22, and afront wall 26 parallel to therear wall 22. Thefront wall 26 has afirst portion 38 spaced from asecond portion 40 by anopening 28. - The
second segment 32 is the same size and shape as thefirst segment 30. - The
third segment 34 is similar to the first andsecond segments front wall 26 extends from oneside wall 24 to theother side wall 24, with anopening 28 extending only about half-way up the height of thefront wall 26. - The
fourth segment 36 is similar again, but with a completefront wall 26 having no opening. - Each
segment vertical passages 42 formed in itsfront wall 26, in thefirst portion 38. Thevertical passages 42 are formed by tubes cast with thefront wall 26. Thevertical passages 42 of eachsegment vertical channels 44 which extend through thelift shaft 20. - The
lift shaft 20 is constructed by first locating thefirst segment 30 in its required position within a building. The building includes apertures (not shown) arranged to align with thevertical tubes 42 of thefirst segment 30. - The
second segment 32 can then be lowered into position atop thefirst segment 30, with theopening 28 and thetubes 42 of thesecond segment 32 aligning with theopening 28 and thetubes 42 of thefirst segment 30. - Similarly, the
third segment 34 and thefourth segment 36 can be lowered into position to complete thelift shaft 20. - The
segments rods 46 such as 20 mm rebar. Arod 46 is inserted within eachchannel 44, extending into the aligned aperture in the building. Therod 46 is long enough to protrude from the top of thechannel 44. Thechannels 44 can then be filled with grout. - The protruding portions of the
rod 46 can be used to provide a ‘starter’ bar for another section of the shaft. - It will be appreciated that the weight of each
segment - It will be further appreciated that the corners of the
lift shaft 20 are cast as such, rather than requiring panels to be bolted together. - Although the invention has been described with the use of two
