Construction of a building

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.

What is claimed is: 
     
         1 . 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.   
     
     
         2 . A method of constructing an inter-storey structure as claimed in  claim 1 , wherein each shaft segment has at least vertical passage extending within a wall of the shaft segment. 
     
     
         3 . A method of constructing an inter-storey structure as claimed in  claim 2 , wherein each passage is formed by a tube cast within a wall of the shaft segment, the tube extending vertically. 
     
     
         4 . A method of constructing an inter-storey structure as claimed in  claim 2 , wherein the passages are aligned to form a vertically extending channel through the inter-storey structure. 
     
     
         5 . A method of constructing an inter-storey structure as claimed in  claim 4 , wherein the method includes the further step of locating reinforcing rods within the vertically extending channel(s) of the inter-storey structure. 
     
     
         6 . A method of constructing an inter-storey structure as claimed in  claim 5 , wherein the method includes the further step of filling the vertically extending channel(s) with a curable substance. 
     
     
         7 . A method of constructing an inter-storey structure as claimed in  claim 5 , wherein the reinforcing rods are longer than the vertically extending channels. 
     
     
         8 . A method of constructing an inter-storey structure as claimed in  claim 7 , wherein the reinforcing rods extend through the first shaft segment and into aligned holes beneath the first shaft segment. 
     
     
         9 . A method of constructing an inter-storey structure as claimed in  claim 7 , wherein the reinforcing rods extend above the top of the inter-storey structure. 
     
     
         10 . A method of constructing an inter-storey structure as claimed in  claim 1 , wherein each shaft segment has a height in the order of 800 mm. 
     
     
         11 . A method of constructing a 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;   sequentially mounting additional wall segments atop the first wall segment to form the 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.   
     
     
         12 . A method of constructing a building wall as claimed in  claim 11 , wherein the method includes the further steps of:
 preforming footing blocks, each footing block being L-shaped in cross section and having at least one vertical channel extending through a vertical portion thereof; and   locating the first wall segment atop the footing blocks such that the vertically extending channel(s) of the wall segment aligns with that of the footing blocks.   
     
     
         13 . 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.   
     
     
         14 . 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.
