Skeleton frames: Assembling Chris Gorse, Joseph Kangwa and Ian Dickinson These slides should be read in conjunction with Emmitt, S. and Gorse, C. (2010) Barry’s Advanced Construction of Buildings. Oxford, Blackwell Publishing
Multi-story skeleton frame
Skeleton frames The following drawing shows a three dimensional view of a steel frame
The completed building
precast stairs are provide a fast and safe installation into the steel frame
Lining the building up The building will twist slightly as it is erected. Before casting any concrete any movement in the structure needs to be corrected. Winches are used to pull the building back in line.
As the building is erected it will need to be pulled into line.
Bracing Triangulation and solid infill walls are used to hold the structure rigid and resist horizontal loads such as wind.
Roof bracing and composite floor provide lateral resistance against wind loads
Fixing the frame together
Roof beam to column connection Beam to column connection
Column to column – spliced and bolted connection Universal column Column prefabricated with end plate All holes for bolts are accurately predrilled off site Splice plate bolted to both top and bottom column End plates welded to the end of each column and bolted together
Splice fixing ready to receive next column
Column to column splice fixing
Steel wedge holds the base in the correct line (position) Base plate welded to column (plate minimum 12mm thick) Steel packing shims fix column at correct level Temporary bund wall (sand) None shrinkable grout fills void left below plate (liquid grout poured into voids) Void formed by cardboard or polystyrene cones, which allows +/- 20mm horizontal tolerance is filled with grout Large washer fixed to bolt to prevent pull out Column base and holding down bolts
Holding down bolts cast in concrete
Holding down bolt in temporary frame which would be cast into a concrete base
Beam connection using end plates welded to the beam Universal column Beam prefabricated with end plate welded to the beam. End plate Holes for bolts predrilled in column and beam end plate ensuring accurate fixing
