Building Methods

Abstract

A method of building a structure, the method including the steps of: 1. fabricating a generally longitudinal, non-steel sub-structure of the structure with a cable retainer attached to, or forming a part of, the substructure and that extends substantially longitudinally therealong; 2. assembling the sub-structure into the structure; 3. inserting a cable into the cable retainer; 4. after step 2, applying a tensile force to the cable relative to the cable retainer; and 5. after step 4, bonding the cable to the cable retainer.

1 . A method of building a structure, the method including the steps of:

       2 . A method of building a structure, the method including the steps of:
 1. fabricating a generally longitudinal, non-steel sub-structure of the structure with a cable retainer attached to, or forming part of, the sub-structure and that extends substantially longitudinally therealong;   2. inserting cable into the cable retainer;   3. after step  2 , applying a tensile force to the cable, relative to the cable retainer; and   4. after step  3 , bonding the cable to the cable retainer; and   5. assembling the sub-structure into a structure.   
   
   
       3 . A method of strengthening, or reducing the deflection of, a built structure, the method including the steps of:
 1. attaching a cable retainer to a generally longitudinal, non-steel sub-structure of the structure with the cable retainer extending substantially longitudinally therealong;   2. inserting cable into the cable retainer;   3. applying a tensile force to the cable, relative to the cable retainer; and   4. after step  3 , bonding the cable to the cable retainer.   
   
   
       4 . The method as claimed in  claim 1 , wherein the cable retainers is adapted to follow the tensile line of resistance the sub-structure is subjected when loaded during use. 
   
   
       5 . The method as claimed in  claim 1 , wherein the method includes assembling at least two sub-structures into a the structure. 
   
   
       6 . The method as claimed in  claim 1 , wherein the method includes inserting at least two cables into the cable retainer. 
   
   
       7 . The method as claimed in  claim 1 , wherein the cable is bonded to the cable retainer by welding. 
   
   
       8 . The method as claimed in  claim 1 , wherein the cable is bonded to the cable retainer by gluing. 
   
   
       9 . The method as claimed in  claim 1 , wherein the cable is bonded to the cable retainer by grouting. 
   
   
       10 . The method as claimed in  claim 1 , wherein the cable is bonded to the cable retainer by expanding the cable retainer relative to the cable or shrinking the cable relative to the cable retainer prior to inserting the cable into the cable retainer. 
   
   
       11 . The method as claimed in  claim 1 , wherein the tensile force is applied to the cable by jacking. 
   
   
       12 . The method as claimed in  claim 1 , wherein the structure is a steel portal frame structure. 
   
   
       13 . The method as claimed in  claim 12 , wherein the structure is produced from I or T section beams or from tubular truss assemblies. 
   
   
       14 . The method as claimed in  claim 13 , wherein when the sub-structure is in the form of an I or T section beam, the cable retainer are is attached to the web of the beam. 
   
   
       15 . The method as claimed in  claim 14 , wherein the cable passes through the flange of the beam. 
   
   
       16 . The method as claimed in  claim 13 , wherein when the sub-structure is a truss assembly, the cable retainer is in the form of one of the tubular members integral with the truss.

       18 . The method as claimed in  claim 11 , wherein the sub-structure is utilised in the columns or walls of the structure. 
   
   
       19 . The method as claimed in  claim 11 , wherein the cable retainer extends within the boundaries of its associated sub-structure. 
   
   
       20 . The method as claimed in  claim 11 , wherein the cable retainer is attached to the sub-structure external the boundaries of the sub-structure. 
   
   
       21 . The method as claimed in  claim 1 , wherein the non-steel sub-structure includes any one of: aluminum and other alloys; carbon fibre; plastics; ceramics; timber; or glass.
